具体而言，该通信资源分配方法是用于在通信系统中将原本指派给蜂窝网络用户的通信资源分配给设备到设备对。其中，在该通信系统中，同时存在若干个传统蜂窝网络用户、若干个设备到设备对用户以及作为无线通信节点的基站；并该不同的传统蜂窝网络用户通过向该基站发送相应的数据信号来实现通信，而该设备到设备对用户还能够相互之间直接进行数据信号的传输，而不需要借助该基站。该设备到设备对用户和传统蜂窝网络用户所使用的终端可为但不限于是智能手机、平板电脑和可穿戴电子设备等便携式电子设备，并且该终端都能够进行关于蜂窝网络协议的无线数据传输。此外，该设备到设备对用户相互之间进行直接数据信号传输时，其满足一定的通信距离约束条件，一般来说，某一设备到设备对信号发射器与另一设备到设备对信号接收器之间的最大距离必须在一阈值限制距离之内，否则，该设备到设备对中的两个终端将无法实现数据信号的直接传输。进一步，两个终端进行设备到设备对的通信时需要 满足一定的数据传输速率和/或数据吞吐量条件，并且该基站还能够检测两个已经构建设备到设备对通信的终端是否需要切换到传统蜂窝网络通信模式。Specifically, the communication resource allocation method is for allocating communication resources originally assigned to a cellular network user to a device-to-device pair in a communication system. Wherein, in the communication system, there are several traditional cellular network users, several device-to-device-to-users, and a base station as a wireless communication node; and the different traditional cellular network users send corresponding data signals to the base station. Communication is achieved, and the device-to-device is also capable of directly transmitting data signals to each other without the need for the base station. The device-to-device terminal for users and traditional cellular network users may be, but is not limited to, portable electronic devices such as smart phones, tablets, and wearable electronic devices, and the terminal is capable of wireless data transmission with respect to cellular network protocols. . In addition, when the device-to-device performs direct data signal transmission to users, it satisfies certain communication distance constraints. Generally, a device-to-device pair signal transmitter and another device-to-device pair signal receiver The maximum distance between them must be within a threshold limit. Otherwise, the two terminals in the device-to-device pair will not be able to directly transmit data signals. Further, two terminals need to perform device-to-device pair communication. A certain data transmission rate and/or data throughput condition is met, and the base station is also capable of detecting whether two terminals that have built device-to-device pair communication need to switch to the traditional cellular network communication mode.
该通信资源分配方法首先通过一设备到设备对识别单元对相应区域内的用户实施需要进行资源分配的设备到设备对的判断划分处理。该设备到设备对识别单元通过获取该区域内不同终端与基站之间的数据传输状态以及不同终端相互之间的数据传输状态，来确定相应的终端是否构成设备到设备对，该设备到设备对识别单元实施该判断划分处理的具体过程为：该设备到设备对识别单元指示基站向该区域内的所有终端发送一短信消息，并获取每个终端针对该短信消息向该基站传送一反馈的响应消息，该设备到设备对识别单元将该每个终端对应的响应时间与一预设响应阈值时间进行比较处理，并基于该比较处理的结果判断某一终端是否处于设备到设备对状态中。当某一终端与该基站处于传统蜂窝网络通信状态，则该终端接收到来自该基站的短信消息后，其会在一定时间长度内向该基站反馈响应消息，而该一定时间长度的最大上限被设为该预设响应阈值，反之，当某一终端处于设备到设备对状态中，则该终端并不会针对来自该基站的短信消息进行一响应消息的反馈，即该基站在任何时段都不会接收到该响应消息；因此，若该响应时间小于或者等于该响应阈值时间，则该设备到设备对识别单元将对应的终端标识为处于设备到设备对状态中，若该响应时间大于该响应阈值时间，则设备到设备对识别单元将对应的终端标识为处于非设备到设备对状态中。随后，该设备到设备对识别单元基于判断为处于设备到设备对状态的终端的地址信息创建设备到设备对集合列表，并将该集合列表保存到一存储单元中，其中该地址信息优选为该终端的MAC地址或者IP地址。此外，该设备到设备对识别单元还能够基于该基站的信号检测结果对该设备到设备对集合列表进行数据修改，以保证该区域中的所有终端的通信状态能够进行更新。The communication resource allocation method first performs a judgment division process of a device-to-device pair that needs to perform resource allocation to a user in a corresponding area by a device-to-device identification unit. The device-to-device pair identification unit determines whether the corresponding terminal constitutes a device-to-device pair by acquiring data transmission status between different terminals and base stations in the area and data transmission status between different terminals, and the device-to-device pair The specific process of the determining unit performing the determining and dividing process is: the device-to-device identification unit instructs the base station to send a short message to all terminals in the area, and obtains a response that each terminal transmits a feedback to the base station for the short message. The device-to-device pair identification unit compares the response time corresponding to each terminal with a preset response threshold time, and determines whether a terminal is in the device-to-device pair state based on the result of the comparison process. When a terminal is in a traditional cellular network communication state with the base station, after receiving the short message from the base station, the terminal feeds back a response message to the base station for a certain length of time, and the maximum upper limit of the certain length of time is set. Responding to the threshold for the preset. Conversely, when a terminal is in the device-to-device pair state, the terminal does not provide feedback for a response message from the base station, that is, the base station does not at any time. Receiving the response message; therefore, if the response time is less than or equal to the response threshold time, the device-to-device identification unit identifies the corresponding terminal as being in the device-to-device pair state, if the response time is greater than the response threshold At the time, the device-to-device pair identification unit identifies the corresponding terminal as being in a non-device-to-device pair state. Then, the device-to-device pair identification unit creates a device-to-device pair set list based on the address information of the terminal determined to be in the device-to-device pair state, and saves the set list to a storage unit, wherein the address information is preferably the The MAC address or IP address of the terminal. In addition, the device-to-device pair identification unit can also perform data modification on the device-to-device pair set list based on the signal detection result of the base station to ensure that the communication status of all terminals in the area can be updated.
一控制单元基于该设备到设备对集合列表，将该集合列表中的所有设备到设备对作为操作目标对象。该控制单元指示一信道信息获取单元获取该设备到设备对中的信道状态信息，其中，该信道状态信息可为但不限于是信道的数据传输速率、信道的信噪比、信道的路径传输损耗、信道的路径传输增益或者信道的数据传输延迟值等信道参数，本领域的技术人员可根据实际需要来设置该 信道状态信息的参数类型。该信道信息获取单元将检测到的信道状态信息传送至一排序单元中，接着该排序单元基于上述某一信道状态信息中的信道参数，对设备到设备对集合列表执行降序排列处理，该降序排列处理的结果为具有较高信道参数的设备到设备对被设置到较靠前的位置，而具有较低信道参数的设备到设备对被设置到较靠后的位置，显然地，具有较高信道参数的设备到设备对，其信道状态好，而具有较低信道参数的设备到设备对，其信道状态较差。同时，该排序单元创建关于该设备到设备对的降序排列表，并将该降序排列表传送至该存储单元中进行保存。随后，该控制单元基于该设备到设备对的降序排列表，选择该降序排列表中排列位置最靠前的设备到设备对作为下一步骤的操作目标对象。A control unit is based on the device-to-device pair list, and all device-to-device pairs in the set list are used as operation target objects. The control unit instructs a channel information acquiring unit to acquire channel state information in the device-to-device pair, where the channel state information may be, but is not limited to, a data transmission rate of the channel, a signal-to-noise ratio of the channel, and a path transmission loss of the channel.

The channel information acquiring unit transmits the detected channel state information to a sorting unit, and then the sorting unit performs a descending order processing on the device-to-device pair set list based on the channel parameters in the certain channel state information, the descending ordering The result of the processing is that the device-to-device pair with higher channel parameters is set to a higher position, while the device-to-device pair with lower channel parameters is set to a later position, apparently, with a higher channel The device-to-device pair of parameters has a good channel state, while the device-to-device pair with lower channel parameters has a poor channel state. At the same time, the sorting unit creates a descending list of the device-to-device pair and transfers the descending row list to the storage unit for saving. Subsequently, the control unit selects the device-to-device pair that is the most advanced in the descending row list as the operation target object of the next step based on the descending list of the device-to-device pair.

The control unit acquires frequency band information corresponding to data communication between the device and the device pair, and performs matching processing on the frequency band information with current frequency band information of all traditional cellular network users in the area, and determines a certain one based on the result of the matching processing. Whether the cellular network user has potential resource sharing with the device-to-device pair. The specific process of the control unit performing the matching process is: the control unit first acquires frequency band information of wireless communication of all cellular network users in the area, and then the control unit uses the band value in the device-to-device pair frequency band information with all the cells. The frequency band corresponding to the network user is compared. If the band value of the device-to-device pair is within the range of the frequency band value of a certain cellular network user, the cellular network user is identified as a potential cellular network user capable of resource sharing. If the band values of several device-to-device pairs are not within the range of the band values of a certain cellular network user, then the cellular network user is identified as a cellular network user that is not capable of resource sharing.
随后，该控制单元创建关于该潜在蜂窝网络用户的列表，并将该列表传送至该信道信息获取单元。该信道信息获取单元基于该潜在蜂窝网络用户列表，获取出该潜在蜂窝网络用户对应的信道系统信息和数据传输速率。其中，该信道系统信息是指某一蜂窝网络用户与某一设备到设备对组成的通信系统中信道的相关参数信息。该信道信息获取单元获取该信道系统信息的具体过程为： 该信道信息获取单元首先获取每个蜂窝网络用户的信道数据传输速率，接着该控制单元将该设备与设备对中的信道数据传输速率与所有蜂窝网络用户的信道数据传输速率进行匹配处理，其中，若该设备与设备对中的信道数据传输速率与某一蜂窝网络用户的信道数据传输速率相匹配，则将该设备与设备对与该蜂窝网络用户构建成一通信系统，并获取其对应的信道系统信息。Subsequently, the control unit creates a list of the potential cellular network users and transmits the list to the channel information acquisition unit. The channel information acquiring unit acquires channel system information and a data transmission rate corresponding to the potential cellular network user based on the potential cellular network user list. The channel system information refers to related parameter information of a channel in a communication system composed of a certain cellular network user and a certain device-to-device pair. The specific process of the channel information acquiring unit acquiring the channel system information is: The channel information acquiring unit first acquires a channel data transmission rate of each cellular network user, and then the control unit matches the channel data transmission rate of the device and the device pair with the channel data transmission rate of all the cellular network users, where If the channel data transmission rate of the device-to-device pair matches the channel data transmission rate of a certain cellular network user, the device and device pair is constructed into a communication system with the cellular network user, and the corresponding channel system is obtained. information.

具体而言，该控制单元在上一步骤中由设备与设备对与蜂窝网络用户构建成的通信系统中进行通信资源的分配操作。该控制单元首先获取该蜂窝网络用户中当前所有频带的使用状态信息，以确定该蜂窝网络用户中处于空闲状态的频带信息；实际上，该控制单元获取该蜂窝网络用户中所有频带的数据吞吐量，若某一频带的数据吞吐量小于一预设标准阈值，则将对应的频带标识为空闲频带，若某一频带的数据吞吐量大于或者等于该预设标准阈值，则将该对应的频带标识为繁忙频带，同时，该控制单元创建关于该空闲频带的列表。随后，该控制单元基于该空闲频带列表，将相应的通信资源分配给该设备到设备对中。Specifically, the control unit performs a resource resource allocation operation in the communication system constructed by the device and the device with the cellular network user in the previous step. The control unit first acquires usage status information of all current frequency bands in the cellular network user to determine frequency band information of the cellular network user in an idle state; in fact, the control unit acquires data throughput of all frequency bands in the cellular network user If the data throughput of a certain frequency band is less than a preset standard threshold, the corresponding frequency band is identified as an idle frequency band. If the data throughput of a certain frequency band is greater than or equal to the preset standard threshold, the corresponding frequency band identifier is identified.
