A resource allocation method according to an embodiment of the present invention, a resource allocation method includes: acquiring a group priority of a target group; defining a group priority range of each resource pool, where the number of the resource pools is not less than one; Counting the number of user terminals that are in communication with the target group, setting the size of each resource pool according to the group priority, the group priority range, and the number of the user terminals; and sending the resource pools The size is given to the user terminal. If the group priority of the target group that the user terminal requests for communication is higher than or equal to the group priority range of the resource pool, the user terminal is allowed to access the resource pool.

Referring first to FIG. 1, FIG. 1 is a schematic flowchart diagram of a resource allocation method according to a first embodiment of the present invention. As shown in FIG. 1 , a resource allocation method provided by the first embodiment of the present invention may include:

S101. Acquire a group priority of the target group.

The group refers to a group of UEs that include multiple UEs in the same communication network as the UE. The target group refers to the target UE group that performs D2D communication with the UE. The UE refers to the connection in the communication network. Acquiring network resources, UEs having information transmitting and receiving functions to be able to establish communication with other UEs, UE groups or eNBs in the communication network;

The UE may perform D2D communication with the target group after acquiring the resource, and the same UE may perform D2D communication with different target groups at the same time. In the same network, the proximity service function entity (Prose Function) manages all groups in a unified manner, giving each group a unique identifier, that is, the group ID, when the same UE and different target groups When D2D communication is performed, the group ID can be distinguished; and when D2D communication is performed between different UEs and different target groups, the group ID of the same group does not change with respect to different UEs.

The group priority is a parameter used to distinguish related groups from different groups to obtain related resources or obtain related rights when there are different groups in the same network.

Optionally, in some possible implementation manners of the present invention, the smaller the value of the Group Priority of the target group that communicates with the UE, the higher the priority level for obtaining the related resource or obtaining the related authority on the target group. On the contrary, the lower.

Optionally, in some possible implementation manners of the present invention, the group priority of the target group that communicates with the UE may be uniquely mapped by the group ID, that is, different groups have different Group IDs, and the UE performs When communicating, it has a different Group Priority.

Optionally, in some possible implementation manners of the present invention, the manner in which the eNB obtains the target group priority may be a process that the eNB actively requests, or may be a process in which the eNB passively receives the target group priority.

It can be understood that, when D2D communication is performed between different UEs and different target groups, the group ID of the same group does not change with respect to different UEs, so that when a certain group needs and different UEs at the same time, When establishing D2D communication, the group priority of the group is unchanged relative to other groups.

S102. Define a group priority range of each resource pool, where the number of the resource pools is not less than one.

The resource pool (Tx Pool) refers to a set of resources, and the eNB can allocate resources to the UE through the resource pool. Therefore, the UE can select a transmission resource that is required by the UE from the resource pool to establish with other UEs or UE groups. connection. Currently, under 3GPP Rel-12, up to four resource pools can be configured for the UE at the same time.

The group priority range (Group Priority Range) may be a parameter defined by the eNB for the Tx Pool, and is used to limit the UE when selecting a transmission resource from the resource pool.

S103. Count the number of user terminals that communicate with the target group, and set the size of each resource pool according to the group priority, the group priority range, and the number of the user terminals.

Optionally, in some possible implementation manners of the present invention, the number of user terminals that communicate with each target group having different group priorities is counted, and the group priority falls within each group priority range according to the group priority. Set the number of user terminals that the target group communicates, and set the size of each resource pool corresponding to the group priority range.

Among them, the larger the resource pool, the more resources that can be allocated, the less anyway.

It can be understood that, after the size of the Tx Pool is set according to the values, the size of each Tx Pool reflects the amount of resources that can be allocated in the priority range, so that the UE can reasonably facilitate resource selection.

S104. Send the size of each resource pool to the user terminal.

It can be understood that after the size of each Tx Pool is set, the size information of each Tx Pool is sent to the user terminal, so that the UE can select the transmission resource in each Tx Pool.

S105. If the group priority of the target group that the user terminal requests to communicate is higher than or equal to the group priority range of the resource pool, the user terminal is allowed to access the resource pool.

It can be understood that, by using such a manner that the UE accesses the Tx Pool, the Tx Pool range that the UE can select is higher, and the target that communicates with the UE, the higher the group priority of the target group that the user terminal requests to communicate. The more communication groups, the more Tx Pools the UE can select, so that the success rate of selecting high-priority target groups for transmission resources is higher.

It should be noted that, in the embodiment of the present invention, step S104 and step S105 have no necessary sequence, that is, the execution order can be replaced.

It can be seen that, in the solution of this embodiment, the group priority of the target group is obtained; the group priority range of each resource pool is defined, and the number of the resource pool is not less than one; the statistics and the target group are The number of the user terminals to be communicated, the size of each resource pool is set according to the group priority, the group priority range, and the number of the user terminals; and the size of each resource pool is sent to the user terminal. . If the group priority of the target group that the user terminal requests for communication is higher than or equal to the group priority range of the resource pool, the user terminal is allowed to access the resource pool. Therefore, the resource allocation can be fully utilized by each Tx Pool, and the UE can flexibly select the transmission resource from each Tx Pool to establish D2D communication with the target group, and the implementation efficiency is high.

Optionally, in some possible implementation manners of the present invention, the number of the resource pools is four.

Optionally, in some possible implementation manners of the present invention, each resource pool group priority range may be defined by halving the total group priority.

For example, in some possible implementation manners of the present invention, when the Group Priority defined by the Prose Function has a total of Pmax=12 levels, that is, 1, 2, . . . 12, and the number of Tx Pools is 4 in total, each can be The Group Priority Range of Tx Pool is defined as: [1-3], [4-6], [7-9], and [9-12].

Optionally, in some possible implementation manners of the present disclosure, the statistics, the number of user terminals that communicate with the target group, according to the group priority, the group priority range, and the user terminal Quantity, set the size of each resource pool, including:

Counting the number of user terminals that communicate with the target group, and setting the group priority based on the positive correlation rule according to the number of the user terminals and the mapping relationship between the group priority and the group priority range The size of the resource pool corresponding to the scope.

The group priority of the target group must fall within a group priority range of one of the resource pools, and the number of the user terminals and the mapping between the group priority and the group priority range The relationship is that the number of user terminals is the number of all user terminals that communicate with a target group whose group priority falls within the group priority range.

Optionally, in some possible implementation manners of the present invention, the determining, according to a positive correlation rule, a size of a resource pool corresponding to the group priority range, including:

When the number of all user terminals that communicate with the target group whose group priority falls within the group priority range is larger, the resource pool corresponding to the group priority range is larger;

The smaller the number of all user terminals communicating with the target group whose group priority falls within the group priority range, the smaller the resource pool corresponding to the group priority range.

For example, in some possible implementation manners of the present invention, when the Group Priority defined by the Prose Function has a total of Pmax=12, that is, 1, 2, . . . 12, the total number of Tx Pools is 4, and each Tx Pool is set. The Group Priority Range is defined as: [1-3], [4-6], [7-9], and [9-12], if the target with the group priority in [1-3] is counted. The number of UEs for group communication is 14, the number of UEs communicating with the target group whose group priority is in the range of [4-6] is 10, and the target with the group priority within the range of [7-9] The number of UEs for group communication is 10, and the number of UEs communicating with the target group whose group priority is in the range of [9-12] is 6, and the Group Priority Range is [1-3], [4- The size ratio of each resource pool of 6], [7-9], and [9-12] is 14:10:10:6.

Optionally, in some possible implementation manners of the present invention, the UE requests a Prose Function to communicate with the target group, and the UE obtains the Group Priority directly from the Prose Function through the PC3 interface.

Optionally, in some possible implementation manners of the present disclosure, the manner of obtaining a group priority of a target group includes:

Obtaining a group priority of the target group from the user terminal by using a RRC message, or acquiring a group priority of the target group from the neighboring service function through a preset interface.

Optionally, in some possible implementation manners of the present invention, the eNB may obtain the Group Priority by the UE through RRC message reporting, or may interact with the Prose Function to obtain the Group Priority through an existing interface, such as S1, S6a, PC4a, and the like.

It can be understood that the manner in which the eNB acquires the Group Priority is the passive acquisition mode, that is, the process is acquired along with the process of receiving the Group Priority sent by the Prose Function.

Optionally, in another possible implementation manner of the present invention, the obtaining a group priority of the target group includes:

Sending a group priority acquisition request to the user terminal or an adjacent service function;

Receiving a group priority returned by the user terminal or the proximity service function entity.

Optionally, in some possible implementation manners of the present invention, the eNB first sends a Group Priority acquisition request to the UE or the Prose Function, and the eNB receives the Group Priority returned by the UE through the RRC message, or through an interface, such as S1, S6a, and PC4a. Indirectly interact with the Prose Function to get the Group Priority returned by the Prose Function.

It can be understood that the manner in which the eNB acquires the Group Priority is the active acquisition mode.

Optionally, in some possible implementation manners of the present invention, the method further includes:

If the user terminal selects a resource that uses the resource pool to communicate with the target group, the user terminal is instructed to wait for the preset time to continue using the resource of the resource pool, where the preset The time is inversely related to the group priority of the target group, and is positively correlated with the preset port average throughput of the user terminal.

Optionally, in some possible implementation manners of the present invention, the average throughput (Tpt) of the preset port is data obtained by the UE to monitor its own PC5 port.

Optionally, in some possible implementation manners of the present invention, when the UE selects a transmission resource that is unsuccessful, the UE waits for a preset time (Backoff_Time) before selecting, and the preset time may be determined by considering Group Priority and Tpt. It is also possible to consider only one of the parameters, and determine that the rule is that Backoff_Time is inversely related to the group priority of the target group, and is positively correlated with the average throughput of the preset port of the UE, that is, if the target group has the group priority. The higher the value of Group Priority, the larger the average throughput. The larger the value of Tpt, the more it can be expressed as Backoff_Time∝Group Priority·Tpt.

It can be understood that, in the above manner, when the group priority is higher, the shorter the waiting time, the smaller the average throughput, and the shorter the waiting time, the UE can make the group with higher Group Priority have more chance to compete for resources. And, if the UE occupies a transmission resource that is not particularly large, there is a certain opportunity to preferentially compete for resources.

Optionally, in some possible implementation manners of the present invention, after the eNB configures the UE with a limited Group ID supported Group Priority and an available Tx Pool in the absence of network coverage, the UE still uses the method from the Tx. The D2D communication is established between the selected transmission resource and the target group in the Pool.

In order to facilitate the better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following is exemplified in conjunction with some specific application scenarios.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a resource allocation method according to a second embodiment of the present invention. As shown in FIG. 2, a resource allocation method according to a second embodiment of the present invention may include:

S201. Obtain a group priority of the target group from the user terminal by using a RRC message.

Optionally, in some possible implementation manners of the present invention, the target group that communicates with the UE The group priority can be uniquely mapped by the Group ID, that is, different groups have different Group IDs, and have different Group Priority when communicating with the UE.

S202. Define a group priority range of each resource pool.

S203. Count the number of user terminals that communicate with the target group, and set the group according to the positive correlation rule according to the number of the user terminals and the mapping relationship between the group priority and the group priority range. The size of the resource pool corresponding to the priority range.

S204. Send the size of each resource pool to the user terminal.

S205. If the group priority of the target group that the user terminal requests to communicate is higher than or equal to the group priority range of the resource pool, the user terminal is allowed to access the resource pool.

S206. If the user terminal selects a resource that uses the resource pool to communicate with the target group, the user terminal is instructed to wait for a preset time before continuing to select and use the resource of the resource pool.

The preset time is inversely related to the group priority of the target group, and the user The preset port average throughput of the terminal is positively correlated.

Optionally, in some possible implementation manners of the present invention, when the UE selects a transmission resource that is unsuccessful, the UE waits for a preset time (Backoff_Time) before selecting, and the preset time may be determined by considering Group Priority and Tpt. It is also possible to consider only one of the parameters, and determine that the rule is that Backoff_Time is inversely related to the group priority of the target group, and is positively correlated with the average throughput of the preset port of the UE, that is, if the target group has the group priority. The higher the value of Group Priority, the larger the average throughput, and the larger the value of Tpt, the more it can be expressed as Backoff_Time∝Group Priority·Tpt.

Optionally, in some possible implementation manners of the present invention, after the eNB configures the UE with a limited Group ID supported Group Priority and an available Tx Pool without network coverage, the UE can still use the method from the UE. A D2D communication is established between the selected transmission resource and the target group in the Tx Pool.

For a better understanding of the present invention and the above-described implementation of the embodiments of the present invention, an embodiment will be described in an interactive manner. Referring to FIG. 3, FIG. 3 is a resource allocation method according to a third embodiment of the present invention. A schematic diagram of a process, wherein, as shown in FIG. 3, a resource allocation method provided by a third embodiment of the present invention may include:

S301. The user terminal requests a group priority of the target group from the neighboring service function entity.

Among them, in the same network, Group Priority is managed by the Prose Function.

Optionally, in a possible implementation manner of the present invention, the UE first requests, from the UE, the Group Priority of the UE to communicate with the target group.

S302. The neighboring service function entity sends the group priority of the target group to the user terminal.

It can be understood that, after the UE requests the Prose Function for the Group Priority of the UE to communicate with the target group, the Prose Function feeds back the Group Priority of the target group to the UE.

S303. The base station simultaneously acquires a group priority of the target group from the neighboring service function entity.

Optionally, in a possible implementation manner of the present invention, the base station acquires the group priority of the target group in a passive manner, that is, when the Prose Function feeds back the Group Priority of the target group to the UE, and the Prose Function passes through the S1. Interfaces such as S6a and PC4a interact to obtain the Group Priority of the target group.

S304. The base station defines a group priority range of each resource pool.

S305. The base station counts the number of user terminals that communicate with the target group, and sets the group priority range according to a positive correlation rule according to the number of user terminals and the mapping relationship between the group priority and the group priority range. The size of the corresponding resource pool.

S306. The base station sends the size of each resource pool to the user terminal.

For example, in some possible implementation manners of the present invention, when the Group Priority defined by the Prose Function has a total of Pmax=12 levels, that is, 1, 2, . . . 12, the total number of Tx Pools is 4, and each Tx is set. The Group Priority Range of the Pool is defined as: [1-3], [4-6], [7-9], and [9-12], if the statistics are in the range of [1-3] with the group priority. The number of UEs communicating by the target group is 14, the number of UEs communicating with the target group whose group priority is in the range of [4-6] is 10, and the group priority is within the range of [7-9]. The number of UEs that the target group communicates is 10, and the number of UEs that communicate with the target group whose group priority is in the range of [9-12] is 6, and the Group Priority Range is [1-3], [4, respectively. The size ratio of each resource pool of -6], [7-9], and [9-12] is 14:10:10:6.

S307. If the group priority of the target group that the user terminal requests to communicate is higher than or equal to the group priority range of the resource pool, the base station allows the user terminal to access the resource pool.

S308. The user terminal selects a resource that uses the resource pool to collide with the target group, where Then, the user terminal waits for the preset time and then continues to select the resource that uses the resource pool.

The preset time is inversely related to the group priority of the target group, and is positively correlated with the preset port average throughput of the user terminal.

For example, in some possible implementation manners of the present invention, when the UE selects a transmission resource unsuccessfully, that is, when a resource selection conflict occurs with other UEs, the UE waits for a certain time (Backoff_Time) to perform selection. The determination of the Backoff_Time is determined according to the average throughput Tpt of the PC5 port monitored by the UE, and the Group Priority of the target group. The determining rule is that the Backoff_Time is inversely related to the group priority of the target group, and the preset port of the UE is The average throughput is positively correlated. That is, if the group priority of the target group is higher, the smaller the value of the Group Priority, the larger the average throughput, and the larger the value of Tpt, that is, the value of Backoff_Time ∝ Group Priority·Tpt.

S309. The user terminal establishes device-to-device communication with the target group by using the selected resource.

It can be understood that, by using the foregoing steps, the UE can select D2D communication from the resource pool to the required transmission resource and the target group, and the group with the higher Group Priority has a chance to compete for resources, and the UE occupies the transmission resource. In exceptional circumstances, there is a certain opportunity to prioritize competition for resources.

The embodiment of the invention further provides a resource allocation device, the device comprising:

An obtaining module, configured to obtain a group priority of the target group;

Specifically, please refer to FIG. 4. FIG. 4 is a schematic structural diagram of a resource allocation apparatus according to a fourth embodiment of the present invention. FIG. 4 is a resource allocation apparatus 400 according to a fourth embodiment of the present invention. Can include:

The second setting module 450 is configured to allow the user terminal to access the resource pool if the group priority of the target group requested by the user terminal is higher than or equal to the group priority range of the resource pool.

It can be understood that, by using such a manner that the UE accesses the Tx Pool, the Tx Pool range that the UE can select is higher, and the target that communicates with the UE, the higher the group priority of the target group that the user terminal requests to communicate. The more communication groups, the more Tx Pools the UE can select, so that it can be guaranteed. The success rate of the target group selected by the high priority is higher.

It should be noted that the signal transmission sequence of the sending module 440 and the second setting module 450 may be transmitted from the sending module 440 to the second setting module 450, or may be transmitted from the second setting module 450 to the sending module 440.

If the group priority of the target group that the user terminal requests for communication is higher than or equal to the group priority range of the resource pool, the resource allocation device 400 allows the user terminal to access the resource pool. Therefore, the resource allocation can be fully utilized by each Tx Pool, and the UE can flexibly select the transmission resource from each Tx Pool to establish D2D communication with the target group, and the implementation efficiency is high.
