Description

Competitive random access method and device

Technical field

本发明涉及通信技术领域，尤其涉及一种竞争性随机接入方法及装置。The present invention relates to the field of communications technologies, and in particular, to a competitive random access method and apparatus.

Background technique

现有移动通信技术中，用户设备(user equipment，UE)在同无线通信网络传输业务数据之前，需先通过随机接入(Random Access)过程来完成连接建立。用户设备随机接入过程可以分为基于非竞争的随机接入和基于竞争的随机接入两种。In the existing mobile communication technology, the user equipment (UE) needs to complete the connection establishment through a random access (Random Access) process before transmitting the service data with the wireless communication network. The user equipment random access procedure can be divided into two types: non-contention based random access and contention based random access.

在基于竞争的随机接入过程中，由用户设备自行选择随机接入资源进行随机接入，若两个用户设备使用相同的随机接入资源(如在LTE某个时频资上两个UE使用相同的前导码)发送接入信号，此时随机接入信号互相干扰而产生碰撞，基站无法识别其中任何一个信号，最终导致随机接入失败，UE需要重新发起接入使得业务发起的接入时延增大。当大量用户设备同时使用基于竞争的随机接入方法接入无线通信网络时，不同用户设备选用相同的随机接入资源进行接入的概率将大大增加，结果会导致大量用户设备无法正常接入，随机接入信道的利用率较低。In the contention-based random access procedure, the user equipment selects the random access resource to perform random access, if two user equipments use the same random access resource (for example, two UEs in the LTE frequency band) The same preamble transmits an access signal. At this time, the random access signals interfere with each other to generate a collision. The base station cannot identify any one of the signals, and finally the random access fails. The UE needs to re-initiate the access so that the service initiates the access. The increase is increased. When a large number of user equipments use the contention-based random access method to access the wireless communication network at the same time, the probability of different user equipments using the same random access resources for access is greatly increased, and as a result, a large number of user equipments cannot be accessed normally. The utilization of the random access channel is low.

detailed description

下面结合说明书附图对本申请实施例做详细描述。The embodiments of the present application are described in detail below with reference to the accompanying drawings.

本申请实施例中用户设备可以为有线终端，也可以为无线终端，例如可以为移动电话、计算机、平板电脑、个人数码助理(英文：personal digital assistant，缩写：PDA)、移动互联网设备(英文：mobile Internet device，缩写：MID)、可穿戴设备、互联网协议(英文：Internet Protocol，缩写：IP)电话、网络打印机和电子书阅读器(英文：e-book reader)等。In the embodiment of the present application, the user equipment may be a wired terminal or a wireless terminal, for example, a mobile phone, a computer, a tablet computer, or a personal digital assistant (English: personal digital Assistant, abbreviation: PDA), mobile Internet device (English: mobile Internet device, abbreviation: MID), wearable device, Internet Protocol (English: Internet Protocol, abbreviation: IP) phone, network printer and e-book reader (English: E-book reader) and so on.

本申请实施例中，第一设备可以为用户设备，可以为基站，可以为家庭基站，例如，Home eNodeB。In this embodiment, the first device may be a user equipment, and may be a base station, and may be a home base station, for example, a Home eNodeB.

本申请实施例中，第二设备可以是指接入网中在空中接口上通过一个或多个扇区或小区与无线终端通信的设备。第二设备可以是全球移动通信系统(Global System for Mobile Communications，GSM)中的基站收发信台(Base Transceiver Station，BTS)，也可以是宽带码分多址移动通信系统(Wideband Code Division Multiple Access，WCDMA)中的基站(Node B)，还可以是LTE中的演进型基站(evolutional Node B，eNB)，本申请实施例对此并不限定。In this embodiment of the present application, the second device may refer to a device in the access network that communicates with the wireless terminal through one or more sectors or cells on the air interface. The second device may be a Base Transceiver Station (BTS) in a Global System for Mobile Communications (GSM), or a Wideband Code Division Multiple Access (Wideband Code Division Multiple Access, The base station (Node B) in the WCDMA system may also be an evolutional Node B (eNB) in the LTE, which is not limited in this embodiment of the present application.

本申请实施例中，用户设备以及作为志愿设备的第一设备是具有D2D(Device-to-Device，设备到设备)能力的设备。D2D能力是指设备之间可以在近距离范围内通过直连链路进行数据传输，不需要通过中心节点进行转发。传统的蜂窝通信技术中，两个用户设备的语音和数据等业务经过各自驻留的基站以及核心网进行交互，当用户设备之间距离很近时可以通过D2D技术实现用户设备之间的交互。In the embodiment of the present application, the user equipment and the first device as the volunteer device are devices with D2D (Device-to-Device) capabilities. The D2D capability means that data can be transmitted between devices through a direct link in a short range without forwarding through the central node. In the traditional cellular communication technology, services such as voice and data of two user equipments interact with each other through the base station and the core network where the user equipment resides. When the distance between the user equipments is very close, the interaction between the user equipments can be realized through the D2D technology.

D2D技术本身的短距离通信特点和直接通信方式使其具有如下优势：UE近距离直接通信方式可实现较高的数据速率、较低的延迟和较低的功耗；利用网络中广泛分布的用户设备以及D2D通信链路的短距离特点，可以实现频谱资源的有效利用；D2D的直接通信方式能够适应本地数据共享需求，提供具有灵活适应能力的数据服务；D2D直接通信能够利用网络中数量庞大且分布广泛的UE以拓展网络的覆盖范围。The short-distance communication characteristics and direct communication mode of D2D technology itself have the following advantages: UE short-distance direct communication mode can achieve higher data rate, lower delay and lower power consumption; utilizes widely distributed users in the network. The short-distance characteristics of the equipment and the D2D communication link can realize the effective utilization of spectrum resources; the direct communication method of D2D can adapt to the local data sharing requirements and provide flexible data services; D2D direct communication can utilize a large number of networks and A wide range of UEs to expand the coverage of the network.

如图1所示，为本申请实施例提供的一种D2D场景示意图。图1中，用户设备可以和基站之间通过蜂窝信号进行通信；用户设备之间也可以通过D2D信号进行通信。FIG. 1 is a schematic diagram of a D2D scenario provided by an embodiment of the present application. In Figure 1, the user equipment can communicate with the base station via cellular signals; the user equipment can also communicate via the D2D signal.

本申请实施例中，志愿设备用于获取第二设备分配的第二随机接入资源，并在接收到用户设备发送的接入请求之后，从获取到的第二随机接入资源中选择出第一随机接入资源，并分配给向其发送接入请求的用户设备。由于第二设备将原来用户设备通过竞争方式获取的随机接入资源通过志愿设备分配给用户设备，避免了用户设备由于在进行随机接入时，采用竞争的方式获得随机接入资源时产生的资源碰撞，提高了用户设备随机接入的成功率，从而提高随机接入资源的利用率。In the embodiment of the present application, the volunteer device is configured to acquire the second random access resource allocated by the second device, After receiving the access request sent by the user equipment, the first random access resource is selected from the obtained second random access resources, and is allocated to the user equipment to which the access request is sent. The second device is configured to allocate the random access resource obtained by the original user equipment in the contention mode to the user equipment through the volunteer device, thereby avoiding the resource generated when the user equipment obtains the random access resource in a competitive manner when performing random access. Collision improves the success rate of random access of user equipment, thereby improving the utilization of random access resources.

基于上述论述，如图2所示，本申请实施例提供的一种竞争性随机接入方法流程示意图。Based on the above discussion, as shown in FIG. 2, a schematic flowchart of a competitive random access method provided by an embodiment of the present application is shown.

如图2所示，该方法具体包括以下步骤：As shown in FIG. 2, the method specifically includes the following steps:

步骤201：第一设备确定成为志愿设备后，接收用户设备发送的接入请求；Step 201: After the first device determines to become a volunteer device, receiving an access request sent by the user equipment.

步骤202：所述第一设备根据所述接入请求向所述用户设备分配第一随机接入资源，以便所述用户设备根据所述第一随机接入资源接入第二设备，所述第一随机接入资源为所述第二设备分配给所述第一设备的第二随机接入资源的子集。Step 202: The first device allocates a first random access resource to the user equipment according to the access request, so that the user equipment accesses the second device according to the first random access resource, where the A random access resource is a subset of the second random access resource allocated by the second device to the first device.

步骤201中，第一设备可以通过以下方式成为志愿设备：In step 201, the first device can become a volunteer device by:

第一设备接收第二设备广播的志愿设备招募消息；其中，第二设备广播的志愿设备招募消息用于指示需要成为志愿设备的第一设备向第二设备发送志愿设备招募响应消息。由于第二设备不确定哪些第一设备可以成为志愿设备，因此，第二设备需要通过志愿设备分配随机接入资源时，可以通过广播志愿设备招募消息指示需要成为志愿设备的第一设备向第二设备发送志愿设备招募消息，从而将发送志愿设备招募消息的第二设备确定为志愿设备。The first device receives the volunteer device recruitment message broadcasted by the second device; wherein the volunteer device recruitment message broadcasted by the second device is used to indicate that the first device that needs to be the volunteer device sends the volunteer device recruitment response message to the second device. Since the second device is not sure which first device can become the volunteer device, when the second device needs to allocate the random access resource through the volunteer device, the first device that needs to be the volunteer device can be indicated by the broadcast volunteer device recruitment message to the second device. The device sends a volunteer device recruitment message, thereby determining the second device that sends the volunteer device recruitment message as the volunteer device.

举例来说，第二设备在检测到网络发生拥塞时，为了减少拥塞，可以通过发送志愿设备招募消息确定出能够分配随机接入资源的志愿设备。For example, when detecting that the network is congested, the second device may determine a volunteer device capable of allocating random access resources by sending a volunteer device recruitment message in order to reduce congestion.

第一设备在确定需要成为志愿设备后，向所述第二设备发送志愿设备招募响应消息,招募响应消息用于指示所述第二设备将所述第一设备确定为志愿设备。第一设备在接收到志愿设备招募消息之后，可以根据自身实际情况确定是否发送志愿设备招募响应消息。可选的，第一设备在确定自身具有D2D 能力时，发送志愿设备招募响应消息。After determining that the device needs to be the volunteer device, the first device sends a volunteer device recruitment response message to the second device, where the recruitment response message is used to instruct the second device to determine the first device as the volunteer device. After receiving the volunteer device recruitment message, the first device may determine whether to send the volunteer device recruitment response message according to its actual situation. Optionally, the first device determines that it has D2D When the ability is available, the volunteer device recruitment response message is sent.

第二设备在接收到第一设备发送的志愿设备招募响应消息之后，可以根据实际情况从发送志愿设备招募响应消息的第一设备中选择多个第一设备作为志愿设备。第二设备也可以将发送志愿设备招募响应消息的所有第一设备都确定为志愿设备。After receiving the volunteer device recruitment response message sent by the first device, the second device may select multiple first devices as the volunteer device from the first device that sends the volunteer device recruitment response message according to actual conditions. The second device may also determine all of the first devices that send the volunteer device recruitment response message as volunteer devices.

举例来说，第二设备将发送志愿设备招募响应消息的所有第一设备中，具备D2D能力的第一设备确定为志愿设备。For example, in the first device that the second device sends the volunteer device recruitment response message, the D2D-capable first device is determined as the volunteer device.

可选的，第二设备在接收到第一设备发送的志愿设备招募响应消息之后，可以向第一设备发送确认消息，以便第一设备确定其已经成为志愿设备。此时，第一设备在接收到所述第二设备根据所述志愿设备招募响应消息发送的确认消息后，确定成为志愿设备。Optionally, after receiving the volunteer device recruitment response message sent by the first device, the second device may send an acknowledgement message to the first device, so that the first device determines that it has become a volunteer device. At this time, after receiving the confirmation message sent by the second device according to the volunteer device recruitment response message, the first device determines to become a volunteer device.

第二设备在接收到第一设备发送的志愿设备招募响应消息之后，若确定所述第一设备可以成为志愿设备，也可以不用特地的向所述第一设备发送确认消息，而是通过向所述第一设备分配第二随机接入资源，从而使得所述第一设备确认自己成为志愿设备。After the second device receives the volunteer device recruitment response message sent by the first device, if it is determined that the first device can become a volunteer device, the second device may not send a confirmation message to the first device, but The first device allocates a second random access resource, so that the first device confirms that it is a volunteer device.

需要说明的是，本申请实施例中的第一随机接入资源可以为以下一种或多种任意组合：时域资源；频域资源；码资源。It should be noted that the first random access resource in the embodiment of the present application may be any one or more of the following combinations: a time domain resource, a frequency domain resource, and a code resource.

相应的，本申请实施例中的第二随机接入资源可以为以下一种或多种任意组合：时域资源；频域资源；码资源。Correspondingly, the second random access resource in the embodiment of the present application may be any one or more of the following combinations: a time domain resource; a frequency domain resource; a code resource.

举例来说，GSM系统中，不包括码资源，那么第一随机接入资源或者第二随机接入资源可能为时域资源和频域资源。For example, in the GSM system, the code resource is not included, and the first random access resource or the second random access resource may be a time domain resource and a frequency domain resource.

举例来说，WCDMA系统中，第一随机接入资源或者第二随机接入资源可能为时域资源和前导码资源。For example, in a WCDMA system, the first random access resource or the second random access resource may be a time domain resource and a preamble resource.

举例来说，LTE系统中，第一随机接入资源或者第二随机接入资源可以为：时域资源、频域资源以及前导码资源。For example, in the LTE system, the first random access resource or the second random access resource may be: a time domain resource, a frequency domain resource, and a preamble resource.

所述第一设备接收用户设备发送的接入请求之前，还可能广播志愿设备指示消息，以便所述用户设备根据所述志愿设备指示消息确定作为志愿设备的第一设备。所述第一设备广播的志愿设备指示消息中可以包括第一设备的标识等信息，用于指示所述第一设备为志愿设备。Before receiving the access request sent by the user equipment, the first device may also broadcast a volunteer device indication message, so that the user equipment determines, as the volunteer device, according to the volunteer device indication message. The first device. The volunteer device indication message broadcasted by the first device may include information such as an identifier of the first device, and is used to indicate that the first device is a volunteer device.

可选的，所述第一设备可以通过D2D资源广播志愿设备指示消息。Optionally, the first device may broadcast the volunteer device indication message by using the D2D resource.

在第一设备广播志愿设备指示消息之后，第一设备就可能接受到用户设备发送的接入请求。After the first device broadcasts the volunteer device indication message, the first device may accept the access request sent by the user device.

第一设备可以通过D2D广播信道接收到用户设备发送的接入请求。第一设备接收到的接入请求为用户设备在确定需要发起随机接入后向所述第一设备发送的。The first device may receive the access request sent by the user equipment through the D2D broadcast channel. The access request received by the first device is sent by the user equipment to the first device after determining that the random access needs to be initiated.

第一设备接收到的接入请求可以为用户设备发起随机接入的条消息，此时用户设备会接收到第二设备发送的随机接入响应。The access request received by the first device may be a message for the user equipment to initiate a random access, and the user equipment receives the random access response sent by the second device.

第一设备接收到的接入请求也可以为用户设备请求第一随机资源的消息，此时用户设备可能会获得第一设备为其分配的第一随机接入资源。The access request received by the first device may also be a message for the user equipment to request the first random resource, and the user equipment may obtain the first random access resource allocated by the first device.

步骤202中，第一设备为用户设备分配的第一随机接入资源是由第二设备分配给第一设备的第二随机接入资源的子集。第一设备会接收到第二设备分配的包括1个或多个第一随机资源的第二随机资源，第一设备会根据用户设备发送的接入请求，从第二随机资源中挑选出一个第一随机资源，并分配给用户设备。In step 202, the first random access resource allocated by the first device to the user equipment is a subset of the second random access resource allocated by the second device to the first device. The first device may receive the second random resource that is allocated by the second device, including one or more first random resources, and the first device selects one of the second random resources according to the access request sent by the user equipment. A random resource and assigned to the user device.

第一设备可以在被第二设备确定为志愿设备之后，接收到用户设备发送接入请求之前，获得第二设备分配的第二随机接入资源。The first device may obtain the second random access resource allocated by the second device after receiving the access request by the user equipment after being determined by the second device as the volunteer device.

此时，第二设备可以根据自身拥有的随机接入资源的数量以及作为志愿设备的第一设备的数量，确定每个第一设备的分配的第二随机接入资源的数量。例如，第二设备将自身拥有的80％的随机接入资源平均分配给所有确定作为志愿设备的第一设备。At this time, the second device may determine the number of allocated second random access resources of each first device according to the number of random access resources owned by the second device and the number of the first devices that are the volunteer devices. For example, the second device distributes 80% of the random access resources owned by itself to all the first devices determined to be volunteer devices.

如果第一设备是接收到用户设备发送接入请求之前，获得第二设备分配的第二随机接入资源，第二设备不能确定向第一设备分配的第二随机接入资源有没有全部被分配给用户设备，因此，第一设备向所述用户设备分配第一随机接入资源之后，还可能需要向第二设备发送随机接入资源分配通知消息，所述随机接入资源分配通知消息用于向所述第二设备指示所述第一设备为所述用户设备所分配的第一随机接入资源，以便所述第二设备根据所述第一设备为所述用户设备所分配的第一随机接入资源向所述用户设备发送随机接入响应。If the first device obtains the second random access resource allocated by the second device before receiving the access request by the user equipment, the second device cannot determine whether all the second random access resources allocated to the first device are all allocated. After the first device allocates the first random access resource to the user equipment, the first device may also need to send a random access resource allocation notification message to the second device. The random access resource allocation notification message is used to indicate to the second device that the first device is the first random access resource allocated by the user equipment, so that the second device is configured according to the first device And transmitting, to the user equipment, a random access response to the first random access resource allocated by the user equipment.

举例来说，第二设备向第一设备分配的第二随机接入资源包括：随机接入资源A、随机接入资源B、随机接入资源C。第一设备将随机接入资源A分配给用户设备之后，向第二设备发送随机接入资源分配通知消息，通知第二设备随机接入资源A已经进行了分配。第二设备接收到随机接入资源分配通知消息之后，可以向用户设备发送与随机接入资源A对应的随机接入响应。For example, the second random access resource allocated by the second device to the first device includes: a random access resource A, a random access resource B, and a random access resource C. After the first device allocates the random access resource A to the user equipment, the first device sends a random access resource allocation notification message to the second device to notify the second device that the random access resource A has been allocated. After receiving the random access resource allocation notification message, the second device may send a random access response corresponding to the random access resource A to the user equipment.

第一设备也可以不向第二设备发送随机接入资源分配通知消息，此时用户设备会通过随机接入信道使用第一设备分配的第一随机接入资源向第二设备发送随机接入请求，从而发起随机接入。The first device may also send a random access resource allocation notification message to the second device, where the user equipment sends a random access request to the second device by using the first random access resource allocated by the first device by using the random access channel. , thereby initiating random access.

举例来说，以LTE系统为例，第一设备向用户设备分配了第一随机接入资源之后，所述用户设备通过所述第一随机接入资源中的时域资源、频域资源以及前导码资源向所述第二设备发送所述随机接入请求，从而发起随机接入。For example, after the first device allocates the first random access resource to the user equipment, the user equipment passes the time domain resource, the frequency domain resource, and the preamble in the first random access resource. The code resource sends the random access request to the second device, thereby initiating random access.

上述方案中，第二设备将原来用于竞争的随机接入资源通过第一设备分配给用户设备，从而避免了用户设备在进行随机接入时的资源碰撞，从而提高了随机接入资源的利用率。In the foregoing solution, the second device allocates the random access resource originally used for the contention to the user equipment by using the first device, thereby avoiding resource collision when the user equipment performs random access, thereby improving the utilization of the random access resource. rate.

第一设备也可以在接收到用户设备发送接入请求之后，获得第二设备分配的第二随机接入资源。此时，第一设备在接收到用户设备发送接入请求之后，先确定向所述第一设备发送接入请求的用户设备的数量；并向所述第二设备发送所述用户设备的数量，再接收所述第二设备根据所述用户设备的数量为所述第一设备分配的第二随机接入资源。The first device may also obtain the second random access resource allocated by the second device after receiving the access request by the user equipment. At this time, after receiving the user equipment to send the access request, the first device determines the number of the user equipment that sends the access request to the first device, and sends the number of the user equipment to the second device. And receiving, by the second device, a second random access resource allocated to the first device according to the number of the user equipment.

举例来说，第一设备可以在接收到第一个接入请求之后，将接收到该接入请求的时间点作为时间起点，并等待预设时间段；所述第一设备确定在该预设时间段内发送接入请求的用户设备的数量，然后将确定出的用户设备的数量发送给第二设备。For example, after receiving the first access request, the first device may use the time point of receiving the access request as a time start point and wait for a preset time period; the first device determines that the preset is The number of user devices that send access requests within the time period, and then the determined user equipment The quantity is sent to the second device.

举例来说，第一设备可以周期性的将一个周期中向所述第一设备发送接入请求的用户设备的数量确定出来，并发送给第二设备。所述周期可以根据实际情况确定，本申请实施例对此并不限定。For example, the first device may periodically determine the number of user equipments that send access requests to the first device in one cycle, and send the information to the second device. The period can be determined according to the actual situation, which is not limited by the embodiment of the present application.

如果第一设备是在接收到用户设备发送接入请求之后获得第二设备分配的第二随机接入资源，第一设备根据用户设备发送的接入请求向所述用户设备分配第一随机接入资源之后，可以向第二设备发送随机接入资源分配通知消息，也可以不向第二设备发送随机接入资源分配通知消息。If the first device obtains the second random access resource allocated by the second device after receiving the access request, the first device allocates the first random access to the user device according to the access request sent by the user device. After the resource, the random access resource allocation notification message may be sent to the second device, or the random access resource allocation notification message may not be sent to the second device.

上述方案中，第一设备接收到的第二设备分配的第二随机接入资源，是第二设备根据向所述第一设备发送接入请求的用户设备的数量确定的，从而能够更有效的利用随机接入资源，降低用户设备进行竞争性随机接入时发生冲突的概率，提高随机接入信道的利用率。In the above solution, the second random access resource allocated by the second device received by the first device is determined by the second device according to the number of user devices that send the access request to the first device, thereby being more effective. The random access resource is used to reduce the probability of collision when the user equipment performs competitive random access, and improve the utilization rate of the random access channel.

第一设备根据用户设备发送的接入请求向所述用户设备分配第一随机接入资源之后，还可能会接收到用户设备根据所述第一随机接入资源发送的用于发起随机接入的随机接入请求。第一设备接收到所述随机接入请求之后，将所述随机接入请求转发给所述第二设备。第一设备可以通过D2D广播信道接收到用户设备发送的随机接入请求。After the first device allocates the first random access resource to the user equipment according to the access request sent by the user equipment, the first device may also receive the user equipment, according to the first random access resource, used to initiate random access. Random access request. After receiving the random access request, the first device forwards the random access request to the second device. The first device may receive the random access request sent by the user equipment through the D2D broadcast channel.

第一设备可以周期性的将接收到的用户设备发送的随机接入请求发送给第二设备，从而实现汇聚用户设备发送的随机接入请求，减少了资源的开销。当然，用户设备还可以直接通过空口将所述随机接入请求发送给第二设备。The first device may periodically send the received random access request sent by the user equipment to the second device, so as to implement a random access request sent by the user equipment, which reduces resource overhead. Of course, the user equipment can also send the random access request to the second device directly through the air interface.

所述第一设备根据所述接入请求向所述用户设备分配第一随机接入资源之后，或者，所述第一设备将用户设备发送的随机接入请求转发给第二设备之后，还可能接收所述第二设备发送的随机接入响应，所述第一设备接收到随机接入响应之后将所述随机接入响应转发给所述用户设备。所述第一设备可以通过D2D广播信道将第二设备发送的随机接入响应发送给用户设备，避免用户设备由于利用较差的蜂窝信号传输随机接入响应而导致用户设备无法接收到随机接入响应或接收随机接入响应时出错，从而避免已发起接入请求的用户设备在认为接入失败时重新发起新的接入或重发接入请求，这些都会使用随机接入资源。因此，通过上述方法，可以减少随机接入资源的使用，提高了随机接入资源的利用率。After the first device allocates the first random access resource to the user equipment according to the access request, or after the first device forwards the random access request sent by the user equipment to the second device, Receiving a random access response sent by the second device, the first device forwarding the random access response to the user equipment after receiving the random access response. The first device may send the random access response sent by the second device to the user equipment by using the D2D broadcast channel, to prevent the user equipment from receiving the random access by using the poor cellular signal to transmit the random access response. An error occurred in response to or receiving a random access response, thereby avoiding an access request being initiated The user equipment re-initiates a new access or retransmission access request when it considers that the access fails, and these all use random access resources. Therefore, by using the foregoing method, the use of random access resources can be reduced, and the utilization rate of random access resources is improved.

当然，所述第二设备也可以将随机接入响应通过空口直接发送给所述用户设备，此时第一设备不会接收到第二设备发送的随机接入响应。Of course, the second device may also directly send the random access response to the user equipment through the air interface, and the first device does not receive the random access response sent by the second device.

第二设备发送的随机接入响应中可以包括多种信息。举例来说，以LTE系统为例，第二设备发送的随机接入响应中可以包括分配给用户设备的临时的C-RNTI(Cell Radio Network Temporary Identity，小区无线网络临时标识)、上行调度授权(Up-Link grant)、TA(Timing Advance，时间提前量)等信息。The random access response sent by the second device may include a variety of information. For example, in the LTE system, the random access response sent by the second device may include a temporary C-RNTI (Cell Radio Network Temporary Identity) allocated to the user equipment, and an uplink scheduling grant ( Up-Link grant), TA (Timing Advance, etc.).

第二设备向用户设备发送随机接入响应之后，可以按照现有的竞争性随机接入的方式继续后面的随机接入过程。举例来说，在LTE系统中，用户设备接收到第二设备发送的随机接入响应之后，会向第二设备发送连接建立请求，并在接收到第二设备发送的连接建立响应之后完成随机接入过程。对于其他系统，在此不再赘述。After the second device sends the random access response to the user equipment, the subsequent random access procedure may be continued according to the existing competitive random access manner. For example, in the LTE system, after receiving the random access response sent by the second device, the user equipment sends a connection establishment request to the second device, and completes the random connection after receiving the connection establishment response sent by the second device. Into the process. For other systems, we will not repeat them here.

下面以第二设备侧为例，描述本申请实施例提供的另一种竞争性随机接入方法。Another competitive random access method provided by the embodiment of the present application is described below by taking the second device side as an example.

如图3所示，本申请实施例提供的一种竞争性随机接入方法流程示意图。As shown in FIG. 3, a schematic flowchart of a competitive random access method provided by an embodiment of the present application is shown.

参见图3，该方法具体包括以下步骤：Referring to FIG. 3, the method specifically includes the following steps:

步骤301：第二设备将第一设备确定为志愿设备；Step 301: The second device determines the first device as a volunteer device.

The first random access resource is a subset of the second random access resource.

步骤301中，第二设备可以有多种实现方式将第一设备确定为志愿设备，一种可能的实现方式为：In the step 301, the second device may determine the first device as the volunteer device in multiple implementation manners. One possible implementation manner is as follows:

第二设备向第一设备发送志愿设备招募消息，志愿设备招募消息用于指示需要成为志愿设备的第一设备向第二设备发送志愿设备招募响应消息；第二设备可以通过广播的方式发送志愿设备招募消息。 The second device sends a volunteer device recruitment message to the first device, where the volunteer device recruiting message is used to indicate that the first device that needs to be the volunteer device sends the volunteer device recruitment response message to the second device; the second device can send the volunteer device by means of broadcast Recruitment news.

所述第二设备接收所述第一设备根据所述志愿设备招募消息发送的志愿设备招募响应消息,招募响应消息用于指示所述第二设备将所述第一设备确定为志愿设备。第二设备可以根据所述志愿设备招募响应消息将所述第一设备确定为志愿设备。第二设备可以将向所述第二设备发送志愿设备招募响应消息的第一设备全部都确定为志愿设备，也可以将其中的一部分确定为志愿设备，本申请实施例对此并不限定。The second device receives the volunteer device recruitment response message sent by the first device according to the volunteer device recruitment message, and the recruitment response message is used to instruct the second device to determine the first device as a volunteer device. The second device may determine the first device as a volunteer device according to the volunteer device recruitment response message. The second device may determine the first device that sends the volunteer device recruitment response message to the second device as the volunteer device, and may also determine a part of the device as the volunteer device, which is not limited in this embodiment of the present application.

第二设备可以是在检测到网络发生拥塞时，发送志愿设备招募消息，以便确定出志愿设备。当然，第二设备在发送志愿设备招募消息时，也可以不用考虑网络是否发生拥塞。The second device may send a volunteer device recruitment message to detect the volunteer device when it detects congestion in the network. Of course, when the second device sends the volunteer device recruitment message, it is also unnecessary to consider whether the network is congested.

可选的，所述第二设备根据接收到的志愿设备招募响应消息确定作为志愿设备的第一设备之后，还可以广播第一设备列表，所述第一设备列表指示出成为志愿设备的第一设备，以便用户设备根据所述第一设备列表确定作为志愿设备的第一设备。第一设备列表中可以包括第一设备标识等信息。Optionally, after determining, by the second device, the first device that is the volunteer device according to the received volunteer device recruitment response message, the first device may also broadcast the first device list, where the first device list indicates that the first device becomes the volunteer device. The device, so that the user equipment determines the first device as the volunteer device according to the first device list. The first device list may include information such as the first device identifier.

步骤302中，第二设备确定作为志愿设备的第一设备之后，可以直接向所述第一设备分配第二随机接入资源。In step 302, after the second device determines the first device as the volunteer device, the second random access resource may be directly allocated to the first device.

需要说明的是，本申请实施例中的所述第一随机接入资源包括以下一种或多种：时域资源；频域资源；码资源。第二随机接入资源可以为以下一种或多种任意组合：时域资源；频域资源；码资源。具体的，可以参考步骤201中的描述，在此不再赘述。It should be noted that the first random access resource in the embodiment of the present application includes one or more of the following: a time domain resource, a frequency domain resource, and a code resource. The second random access resource may be any combination of one or more of the following: a time domain resource; a frequency domain resource; a code resource. For details, refer to the description in step 201, and details are not described herein again.

所述第二设备向所述第一设备分配第二随机接入资源之后，还可能接收到第一设备发送的随机接入资源分配通知消息，随机接入资源分配通知消息用于指示所述第一设备为所述用户设备所分配的第一随机接入资源。 After the second device allocates the second random access resource to the first device, the second device may also receive a random access resource allocation notification message sent by the first device, where the random access resource allocation notification message is used to indicate the A device is a first random access resource allocated by the user equipment.

第二设备可以根据接收到的所述第一设备发送的随机接入资源分配通知消息确定所述第一设备为所述用户设备所分配的第一随机接入资源。当然，第一设备也可以不向第二设备发送随机接入资源分配通知消息。The second device may determine, according to the received random access resource allocation notification message sent by the first device, the first random access resource allocated by the first device to the user equipment. Of course, the first device may also not send a random access resource allocation notification message to the second device.

第二设备还可以根据向第一设备发送接入请求的用户设备的数量确定向第一设备分配的第二随机接入资源。具体的，第二设备接收所述第一设备发送的用户设备的数量；所述第二设备根据所述用户设备的数量确定分配给所述第一设备的第二随机接入资源。The second device may further determine the second random access resource allocated to the first device according to the number of user equipments that send the access request to the first device. Specifically, the second device receives the number of user equipments sent by the first device, and the second device determines, according to the number of the user equipments, a second random access resource that is allocated to the first device.

举例来说，第二设备可以周期性的接收到第一设备发送的用户设备的数量，并根据所述用户设备的数量向第一设备分配第二随机接入资源。For example, the second device may periodically receive the number of user equipments sent by the first device, and allocate the second random access resources to the first device according to the number of the user equipments.

同样的，第二设备向所述第一设备分配随机接入资源之后，还可能接收到第一设备发送的随机接入资源分配通知消息。Similarly, after the second device allocates the random access resource to the first device, the second device may also receive the random access resource allocation notification message sent by the first device.

第二设备向所述第一设备分配随机接入资源之后，会根据所述第一设备为所述用户设备所分配的第一随机接入资源向所述用户设备发送随机接入响应。After the second device allocates the random access resource to the first device, the second device sends a random access response to the user equipment according to the first random access resource allocated by the first device for the user equipment.

本申请实施例中，第二设备可以在接收到第一设备发送的随机接入资源分配通知消息之后，向用户设备发送随机接入响应。第一设备一般是在向用户设备分配了随机资源之后，向第二设备发送随机接入资源分配通知消息。In this embodiment, after receiving the random access resource allocation notification message sent by the first device, the second device may send a random access response to the user equipment. The first device generally sends a random access resource allocation notification message to the second device after the random resource is allocated to the user equipment.

第二设备接收到第一设备发送的随机接入资源分配通知消息之后，就可以确定第一设备已经分配给用户设备的第一随机接入资源，因此第二设备可以根据已经分配给用户设备的第一随机接入资源向用户设备发送随机接入响应。此时，用户设备相当于是通过发送的接入请求发起随机接入。After the second device receives the random access resource allocation notification message sent by the first device, the first device may determine the first random access resource that the first device has allocated to the user device, so the second device may be configured according to the device that has been allocated to the user device. The first random access resource sends a random access response to the user equipment. At this time, the user equipment is equivalent to initiating random access by using the sent access request.

本申请实施例中，第二设备还可以在根据用户设备的数量向第一设备分配第二随机接入资源之后，向用户设备发送随机接入响应。In the embodiment of the present application, the second device may further send a random access response to the user equipment after allocating the second random access resource to the first device according to the number of the user equipment.

由于第二设备是根据用户设备的数量向第一设备分配的随机接入资源，因此第二设备可以确定第一设备已经分配给用户设备的第一随机接入资源，因此便可以向用户设备发送随机接入响应。此时，用户设备相当于是通过发送的接入请求发起随机接入。 Since the second device is a random access resource allocated to the first device according to the number of the user equipment, the second device may determine that the first device has been allocated to the first random access resource of the user equipment, and thus may send the information to the user equipment. Random access response. At this time, the user equipment is equivalent to initiating random access by using the sent access request.

本申请实施例中，第二设备还可以在接收到用户设备根据第一设备分配的随机接入资源发送的随机接入请求之后，向所述用户设备发送随机接入响应。所述第二设备还可以接收所述第一设备转发的用于发起随机接入的随机接入请求，所述随机接入请求为所述用户设备根据所述第一随机接入资源发送给所述第一设备的。第一设备在接收到用户设备发送的用于发起随机接入的随机接入请求之后，将所述随机接入请求转发给所述第一设备。In this embodiment, the second device may further send a random access response to the user equipment after receiving the random access request sent by the user equipment according to the random access resource allocated by the first device. The second device may further receive, by the first device, a random access request for initiating a random access, where the random access request is sent by the user equipment according to the first random access resource. The first device. After receiving the random access request sent by the user equipment for initiating the random access, the first device forwards the random access request to the first device.

举例来说，以LTE系统为例，第一设备向用户设备分配了第一随机接入资源之后，所述用户设备通过所述第一随机接入资源中的时域资源以及频域资源向所述第二设备发送所述第一随机接入资源中的前导码资源，从而发起随机接入。For example, after the first device allocates the first random access resource to the user equipment, the user equipment uses the time domain resource and the frequency domain resource in the first random access resource. The second device sends the preamble resource in the first random access resource, thereby initiating random access.

上述三种情况中，第二设备向用户设备发送随机接入响应之后，可以按照现有的竞争性随机接入的方式继续后面的随机接入过程，在此不再赘述。同时，需要说明的是，第二设备发送的随机接入响应中可以包括分配给用户设备的临时的C-RNTI、Up-Link grant、TA等信息。第二设备发送的随机接入响应的具体内容可以参考现有通信标准中的规定，在此不再赘述。In the foregoing three cases, after the second device sends the random access response to the user equipment, the subsequent random access process may be continued according to the existing competitive random access mode, and details are not described herein again. In addition, it should be noted that the random access response sent by the second device may include temporary C-RNTI, Up-Link grant, TA, and the like allocated to the user equipment. The specific content of the random access response sent by the second device may be referred to the provisions in the existing communication standard, and details are not described herein again.

第二设备发送随机接入响应时，可以根据所述第一设备为所述用户设备所分配的随机接入资源在空口直接向所述用户设备发送随机接入响应，也可以根据所述第一设备为所述用户设备所分配的第一随机接入资源向所述第一设备发送随机接入响应，以便所述第一设备将所述随机接入响应转发给所述用户设备。When the second device sends the random access response, the random access resource that is sent by the first device to the user equipment may be directly sent to the user equipment in the air interface, or may be sent according to the first The device sends a random access response to the first device for the first random access resource allocated by the user equipment, so that the first device forwards the random access response to the user equipment.

第二设备将随机接入响应通过第一设备转发给用户设备，可以避免第二设备由于利用较差的蜂窝信号传输随机接入响应而导致用户设备无法接收到随机接入响应或接收随机接入响应时出错，从而避免已发起接入请求的用户设备在认为接入失败时重新发起新的接入或重发接入请求，这些都会使用随机接入资源。因此，通过上述方法，可以减少随机接入资源的使用，提高了随机接入资源的利用率。The second device forwards the random access response to the user equipment by using the first device, and may prevent the second device from receiving the random access response by using the poor cellular signal, and the user equipment cannot receive the random access response or receive the random access. An error occurs in response, so that the user equipment that has initiated the access request re-initiates a new access or retransmission access request when it considers that the access fails, and these all use random access resources. Therefore, by using the foregoing method, the use of random access resources can be reduced, and the utilization rate of random access resources is improved.

下面以用户设备侧为例，描述本申请实施例提供的另一种竞争性随机接入方法。The following uses the user equipment side as an example to describe another competitive random connection provided by the embodiment of the present application. Into the method.

The first device list may include information such as an identifier of the first device. For example, the user equipment may determine, according to the first device list, a first device with a strong signal strength and a small load in the first device list, and send an access request to the first device.

步骤402中，用户设备在接收到所述第一设备分配的第一随机接入资源之后，可以根据所述第一接入随机资源向第二设备发送随机接入请求，从而发起随机接入，并在发起随机接入之后接收第二设备发送的随机接入响应。用户设备也可以不发送随机接入请求消息，并在接收到第一设备分配的第一随机接入资源之后接收第二设备发送的随机接入响应。In step 402, after receiving the first random access resource allocated by the first device, the user equipment may send a random access request to the second device according to the first access random resource, thereby initiating random access. And receiving a random access response sent by the second device after initiating the random access. The user equipment may also not send the random access request message, and receive the random access response sent by the second device after receiving the first random access resource allocated by the first device.

举例来说，LTE系统中，用户设备在接收到第一设备分配的第一随机接入资源之后，通过所述第一随机接入资源中的时域资源以及频域资源将所述随机接入资源中的前导码资源发送给第二设备，从而发起随机接入。当然，用户设备也可以不用发送前导码资源，用户设备可以通过步骤401中发送给第一设备的接入请求发起随机接入。 For example, in the LTE system, after receiving the first random access resource allocated by the first device, the user equipment uses the time domain resource and the frequency domain resource in the first random access resource to perform the random access. The preamble resource in the resource is sent to the second device to initiate random access.

需要说明的是，本申请实施例中的第一随机接入资源可以包括以下一种或多种：时域资源；频域资源；码资源。第二随机接入资源可以包括以下一种或多种：时域资源；频域资源；码资源。具体可以参考步骤201中的描述，在此不再赘述。It should be noted that the first random access resource in the embodiment of the present application may include one or more of the following: a time domain resource, a frequency domain resource, and a code resource. The second random access resource may include one or more of the following: a time domain resource; a frequency domain resource; a code resource.

Forwarding by the first device to the user equipment.

可选的，用户设备接收到第一设备通过D2D广播信道发送的随机接入响应。第二设备将随机接入响应通过第一设备转发给用户设备，可以避免第二设备由于利用较差的蜂窝信号传输随机接入响应而导致用户设备无法接收到随机接入响应或接收随机接入响应时出错，从而避免已发起接入请求的用户设备在认为接入失败时重新发起新的接入或重发接入请求，这些都会使用随机接入资源。因此，通过上述方法，可以减少随机接入资源的使用，提高随机接入信道的容量。Optionally, the user equipment receives the random access response sent by the first device by using a D2D broadcast channel. The second device forwards the random access response to the user equipment by using the first device, and may prevent the second device from receiving the random access response by using the poor cellular signal, and the user equipment cannot receive the random access response or receive the random access. An error occurs in response, so that the user equipment that has initiated the access request re-initiates a new access or retransmission access request when it considers that the access fails, and these all use random access resources. Therefore, by the above method, the use of random access resources can be reduced, and the capacity of the random access channel can be improved.

用户设备接收到第二设备发送的随机接入响应中可以包括多种信息，具体可以参考现有通信标准中的规定，在此不再赘述。The user equipment may receive a variety of information in the random access response sent by the second device. For details, refer to the provisions in the existing communication standards, and details are not described herein.

举例来说，在LTE系统中，用户设备接收到第二设备发送的随机接入响应中可以包括分配给用户设备的前导码资源的索引、临时的C-RNTI、Up-Link grant、TA等信息。用户设备若确定接收到的随机接入响应中前导码资源的索引与自己发送前导码资源时使用的索引相同，则认为成功接收到对应的随机接入响应。TA用于指定用户设备上行同步所需要的时间调整量。Up-Link grant指定了分配给用户设备发送后续的连接请求消息(如RRC Connection Request)所使用的上行时频资源。For example, in the LTE system, the user equipment receives the index of the preamble resource allocated to the user equipment, the temporary C-RNTI, the Up-Link grant, the TA, and the like in the random access response sent by the second device. . If the user equipment determines that the index of the preamble resource in the received random access response is the same as the index used when transmitting the preamble resource, the user equipment considers that the corresponding random access response is successfully received. TA is used to specify the amount of time adjustment required for uplink synchronization of user equipment. The Up-Link grant specifies the uplink time-frequency resource used by the user equipment to send subsequent connection request messages (such as RRC Connection Request).

用户设备向第二设备发送连接请求消息之后，还会接收到第二设备发送的连接请求响应消息(如RRC Connection Setup)，用户设备从而完成随机接入。After the user equipment sends the connection request message to the second device, it also receives a connection request response message (such as RRC Connection Setup) sent by the second device, and the user equipment completes the random connection. In.

用户设备向第二设备发送的连接请求消息，以及接收到的第二设备发送的连接请求响应消息中携带的参数，以及发送的方式可以参考现有竞争性随机接入中的规定，在此不再赘述。The connection request message sent by the user equipment to the second device, and the parameter carried in the connection request response message sent by the second device, and the manner of sending may refer to the provisions in the existing competitive random access, and Let me repeat.
