Description

Multicast service transmission device and method

Technical field

本发明涉及无线通信领域，尤其涉及一种多播业务传输装置及方法。The present invention relates to the field of wireless communications, and in particular, to a multicast service transmission apparatus and method.

Background technique

多播技术是一种点对多点发送数据的技术，具体的，多播技术是指一个数据发送设备通过同一共享信道向多个数据接收设备发送相同的数据。The multicast technology is a technology for transmitting data from point to multipoint. Specifically, the multicast technology refers to a data transmitting device transmitting the same data to multiple data receiving devices through the same shared channel.

目前，第三代合作伙伴计划(英文：3rd Generation Partnership Project，简称：3GPP)中使用多播技术的有多媒体广播组播业务(英文：Multimedia Broadcast Multicast Services，简称：MBMS)和单小区点到多点(英文：single cell point to multipoint，简称：SC-PTM)技术。以利用多播技术传输多媒体广播组播业务为例，基站通过物理多播信道(英文：Physical Multicast Channel，简称：PMCH)向小区内的多个用户设备(英文：User Equipment，简称：UE)同时发送MBMS，使得多个UE同时通过读取PMCH获取MBMS。At present, the 3rd Generation Partnership Project (English: 3rd Generation Partnership Project, 3GPP) uses multimedia broadcast multicast service (English: Multimedia Broadcast Multicast Services, MBMS for short) and single-cell point-to-multiple Point (English: single cell point to multipoint, referred to as: SC-PTM) technology. For example, the multicast broadcast service is transmitted by using the multicast technology. The base station uses a physical multicast channel (English: Physical Multicast Channel, PMCH for short) to simultaneously access multiple user equipments in the cell (English: User Equipment, UE for short). The MBMS is transmitted such that multiple UEs simultaneously acquire the MBMS by reading the PMCH.

如图1所示，UE正在通过多播承载接收小区1发送的多播业务A，当UE从小区1切换至没有发送多播业务A的小区2时，UE通过读取小区2的广播消息确定小区2没有发送多播业务A后，先与小区2建立单播承载，以便通过单播承载继续接收多播业务A。在UE先切换至小区2、再建立单播承载的过程中，UE接收多播业务A会出现业务中断现象。为避免出现业务中断现象，如图2所示，UE在从小区1移动至小区2的过程中，UE先与小区1建立单播承载，以继续通过单播承载接收小区1发送的多播业务A，再从小区1切换至小区2。但采用这种技术方案，由于小区1通过多播承载和建立单播承载分别调度UE接收多播业务A的数据包，造成资源浪费。As shown in FIG. 1, the UE is receiving the multicast service A sent by the cell 1 through the multicast bearer. When the UE switches from the cell 1 to the cell 2 that does not send the multicast service A, the UE determines by reading the broadcast message of the cell 2. After the cell 2 does not send the multicast service A, it first establishes a unicast bearer with the cell 2, so as to continue to receive the multicast service A through the unicast bearer. In the process of the UE first switching to the cell 2 and then establishing the unicast bearer, the UE receives the multicast service A and the service interruption occurs. To avoid the service interruption phenomenon, as shown in FIG. 2, in the process of the UE moving from the cell 1 to the cell 2, the UE first establishes a unicast bearer with the cell 1 to continue to receive the multicast service sent by the cell 1 through the unicast bearer. A, then switch from cell 1 to cell 2. However, in this technical solution, the cell 1 schedules the UE to receive the data packet of the multicast service A through the multicast bearer and the unicast bearer, respectively, resulting in waste of resources.

实施例五Embodiment 5

实施例五与实施例一对应的，Embodiment 5 corresponds to the first embodiment,

如图16所示，本发明实施例提供了一种多播业务传输方法，该方法执行主体为基站，包括：As shown in FIG. 16, an embodiment of the present invention provides a method for transmitting a multicast service, where the method is performed by a base station, including:

S1601：基站建立与用户设备UE的单播承载；S1601: The base station establishes a unicast bearer with the user equipment UE.

S1602：基站确定建立的单播承载用于传输UE接收的多播业务；S1602: The eNB determines that the established unicast bearer is used to transmit the multicast service received by the UE.

S1603：基站在确定UE所在的当前小区正在利用多播承载传输多播业务时，调度多播承载传输多播业务的数据包，以使UE在多播承载上接收多播业务的数据包，且不调度UE在单播承载上接收多播业务的数据包。S1603: The base station determines that the current cell where the UE is located is using the multicast bearer to transmit the multicast service. When the multicast bearer transmits the data packet of the multicast service, the UE receives the data packet of the multicast service on the multicast bearer, and does not schedule the UE to receive the data packet of the multicast service on the unicast bearer.

本实施例中，基站建立与UE的单播承载可以避免UE从当前小区切换到目标小区时，基站向UE传输多播业务中断。In this embodiment, the base station establishes a unicast bearer with the UE to prevent the UE from transmitting the multicast service interruption to the UE when the UE switches from the current cell to the target cell.

本实施例中，基站建立与UE的单播承载后，单播承载关联的多播业务的数据包到达基站时，若基站不调度UE在单播承载上接收多播业务的数据包，则不会占用单播承载资源，以达到节省资源的目的。避免现有技术中基站调度其他UE在多播承载上接收多播业务，调度当前UE在单播承载上接收多播业务，造成的资源浪费问题。In this embodiment, after the base station establishes a unicast bearer with the UE, when the data packet of the multicast service associated with the unicast bearer arrives at the base station, if the base station does not schedule the UE to receive the data packet of the multicast service on the unicast bearer, The unicast bearer resources are occupied to save resources. In the prior art, the base station schedules other UEs to receive the multicast service on the multicast bearer, and schedules the current UE to receive the multicast service on the unicast bearer, which causes waste of resources.

本实施例中，基站在确定所述UE所在的当前小区没有利用多播承载传输所述多播业务时，调度所述UE在所述单播承载上接收所述多播业务的数据包。In this embodiment, the base station, when determining that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service, schedules the UE to receive the data packet of the multicast service on the unicast bearer.

可选的，基站可以通过以下方法确定所述UE所在的当前小区没有利用多播承载传输所述多播业务：Optionally, the base station may determine, by using the following method, that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service:

方法1、基站收到控制多播业务的服务器发送的停止多播业务的通知消息时，确定所述UE所在的当前小区没有利用多播承载传输所述多播业务。Method 1, when the base station receives the notification message of stopping the multicast service sent by the server that controls the multicast service, it is determined that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service.

方法2、基站确定当前小区内接收多播业务的UE数量小于预设的数值时，确定所述UE所在的当前小区没有利用多播承载传输所述多播业务。Method 2: The base station determines that the number of UEs receiving the multicast service in the current cell is less than a preset value, and determines that the current cell where the UE is located does not use the multicast bearer to transmit the multicast service.

方法2中基站会要求UE上报是否接收多播业务，基站根据各UE上报的该信息，确定当前小区内接收该多播业务的UE的数量。In the method 2, the base station may request the UE to report whether to receive the multicast service, and the base station determines the number of UEs that receive the multicast service in the current cell according to the information reported by each UE.

本实施例中，基站可以在接收到核心网设备发送的单播承载建立请求时，确定UE处在当前小区的边缘区域，该单播承载建立请求用于请求基站建立与UE的单播承载，核心网设备向基站发送单播承载建立请求是UE通过应用服务器向核心网设备发送单播承载建立请求触发的。In this embodiment, when receiving the unicast bearer setup request sent by the core network device, the base station may determine that the UE is in an edge region of the current cell, where the unicast bearer setup request is used to request the base station to establish a unicast bearer with the UE. The sending of the unicast bearer setup request by the core network device to the base station is triggered by the UE sending a unicast bearer setup request to the core network device by using the application server.

可选的，基站在建立与UE的单播承载之前，可以向UE发送单播承载建立阈值，以使UE根据接收的单播承载建立阈值确定需要建立单播承载时，触发基站建立与UE的单播承载。具体的，基站向UE发送单播承载建立阈值， UE确定当前小区的单播承载建立指标，当单播承载建立指标小于或等于单播承载建立阈值时，可以确定自身处在当前小区的边缘区域。此时，UE通过应用服务器向核心网设备发送单播承载建立请求，以触发核心网设备请求基站建立与UE的单播承载。可选的，基站通过广播消息或专用消息向UE发送单播承载建立阈值，专用消息包括单播承载重配置消息，但不限于此。Optionally, the eNB may send a unicast bearer setup threshold to the UE before establishing the unicast bearer with the UE, so that the UE determines that the unicast bearer needs to be established according to the received unicast bearer setup threshold, and triggers the base station to establish the UE with the UE. Unicast bearer. Specifically, the base station sends a unicast bearer establishment threshold to the UE, The UE determines the unicast bearer establishment indicator of the current cell. When the unicast bearer setup indicator is less than or equal to the unicast bearer setup threshold, the UE may determine that it is in the edge region of the current cell. At this time, the UE sends a unicast bearer setup request to the core network device through the application server, to trigger the core network device to request the base station to establish a unicast bearer with the UE. Optionally, the base station sends a unicast bearer setup threshold to the UE by using a broadcast message or a dedicated message, where the dedicated message includes a unicast bearer reconfiguration message, but is not limited thereto.

其中，单播承载建立阈值可以为信号强度的阈值，此时单播承载建立指标为信号强度；单播承载建立阈值可以为信号质量指标的阈值，此时单播承载建立指标包括信号质量指标，但不限于此。以信号强度的阈值作为单播承载建立阈值为例，由于信号强度随着当前地理位置与小区中心位置的距离的增加而减弱，当UE处于小区的边缘区域时，信号强度较弱。因此，UE可以通过检测当前地理位置的信号强度，并比较当前地理位置的信号强度和信号强度的阈值，来判断UE是否处于当前小区的边缘区域，进而在确定处于当前小区的边缘区域时，确定需要触发基站建立与UE的单播承载。The unicast bearer establishment threshold may be a signal strength threshold, and the unicast bearer establishment indicator may be a signal strength; the unicast bearer establishment threshold may be a signal quality indicator threshold, and the unicast bearer establishment indicator includes a signal quality indicator. But it is not limited to this. Taking the threshold of the signal strength as a unicast bearer establishment threshold, the signal strength is weakened as the distance between the current geographic location and the cell center location increases, and the signal strength is weak when the UE is in the edge region of the cell. Therefore, the UE can determine whether the UE is in the edge region of the current cell by detecting the signal strength of the current geographic location and comparing the signal strength of the current geographic location with the threshold of the signal strength, and then determining when the edge region of the current cell is determined. The base station needs to be triggered to establish a unicast bearer with the UE.

本实施例中，针对基站确定建立的单播承载用于传输UE接收的多播业务，可以有两种实现方式：In this embodiment, the unicast bearer that is determined by the base station to be used for transmitting the multicast service received by the UE may be implemented in two ways:

Indicators, but are not limited to this. Taking the threshold of the signal strength as a unicast bearer establishment threshold, the signal strength is weakened as the distance between the current geographic location and the cell center location increases, and the signal strength is weak when the UE is in the edge region of the cell. Therefore, the UE can detect the signal strength of the current geographic location and compare the signal strength and the current geographic location. The threshold of the strength of the number is used to determine whether the UE is in the edge region of the current cell. When determining the edge region of the current cell, it is determined that the base station needs to be triggered to establish a unicast bearer with the UE.
