To accommodate a diversified network application scenario, different access network devices may be configured with different frame structures. If different frame structures are configured between two adjacent access network devices, a downlink timeslot of one access network device (denoted as access network device 1) will cause interference to an uplink timeslot of another adjacent access network device (denoted as access network device 2), which will cause interference to the access network device 2 when the access network device 1 uses the downlink timeslot to transmit data, and affect uplink transmission performance of the access network device 2.

In the description of the present application, unless otherwise indicated, the meaning of "a plurality" means two or more.

The following explains terms related to the embodiments of the present application, so as to facilitate the understanding of readers.

(1) Co-building sharing

Co-building sharing refers to a networking scheme for sharing carrier resources among different operators. Through co-building sharing, the service of a plurality of operators can be borne on one access network device, or a plurality of types of service can be borne on one access network device, so that the networking cost of the operators is reduced.

Co-building sharing includes: independent carrier sharing, carrier-level shared carrier sharing, traffic-type-level shared carrier sharing, and unlimited-level shared carrier sharing.

In the application scenario of independent carrier sharing, the access network device configures an independent carrier for one type of service of one operator. For example, the access network device configures an independent carrier C for the type B traffic of operator a.

In an application scenario of carrier-level shared carrier sharing, an access network device configures one shared carrier for multiple types of services of one carrier. For example, the access network device configures the shared carrier G for all of the type D, type E, and type F traffic of operator a.

In an application scenario of shared carrier sharing at the traffic type level, an access network device configures one shared carrier for one type of traffic of multiple operators. For example, the access network device configures a shared carrier Q for each of the traffic of type J of operator a, operator H, and operator I.

Under the application scenario of unlimited level shared carrier sharing, the access network device configures one shared carrier for multiple types of services of multiple operators. For example, the access network device configures the shared carrier M for each of the type J, type Q, and type L traffic of operator a, operator H, and operator I.

It should be noted that, the frequency band of the antenna radio frequency of the current access network device is continuously improved, the coverage area of the access network device is correspondingly reduced, and the number of access network devices required to be deployed for covering the same area is continuously increased. In addition, current access network devices typically employ multiple-in multiple-out (multiple in multiple out, MIMO) technology, and the number of antennas of the access network devices increases substantially, which also results in an increase in the number of access network devices deployed in the same area. In the case that the number of the access network devices to be deployed is increased, the cost of network construction of the operators is also greatly increased. The above-mentioned shared networking scheme of co-building can solve the problem that the network construction cost of the operator increases that the access network equipment increases at present very well.

(2) 5G quality of service identification code (5G quality of service identifier,5QI)

The 5QI is used to indicate the traffic characteristics of different traffic in the 5G network. For example, the traffic characteristics of guaranteed bit rate (guaranteed bit rate, GBR) traffic, the traffic characteristics of non-guaranteed bit rate (non-guaranteed bit rate, non-GBR) traffic. In fourth generation (fourth generation, 4G) networks, the traffic characteristics of different traffic can be represented by quality of service class identification codes (QCI) of SERVICE CLASS IDENTIFIER.

The 5QI may be acquired by session management function-unified data management function registration information (session management function-unified DATA MANAGEMENT registration, SMF-UDM registration). The 5QI may also be obtained from an initial context setup request (i.e. INITIAL CONTEXT SETUP REQUEST) message or a protocol data unit session resource setup request (i.e. PDU SESSION RESOURCE SETUP REQUEST) message of the N2 interface when the terminal device initiates a service request.

It should be noted that 5QI may be used to characterize the service characteristics of one service, or may be used to characterize the service characteristics of one service (or multiple services).

Table 1 below is 5QI for multiple types of GBR traffic, as an example.

As shown in table 1, 5QI may include at least one of: a 5QI Value (5 QI Value), a default priority (Default Priority Level), a packet delay Budget (PACKET DELAY Budget), a packet error rate (Packet Error Rate), a default average window (Default Averaging Window), typical traffic (sample Services).

TABLE 1

As yet another example, table 2 below is a 5QI mapping table for multiple types of non-GBR traffic.

As shown in table 2, the category of information included in the 5QI of the non-GBR service is the same as the category of information included in the 5QI of the GBR service.

TABLE 2

It should be noted that the 5QI Value (i.e., 5QI Value) in 5QI may be used to distinguish GBR traffic from non-GBR traffic. For example, when the 5QI value is 1,2, 3, 4, 65, 66, 67, it may be used to characterize the traffic as GBR traffic. When the 5QI value is 5, 6, 7, 8, 9, 69, 70, it can be used to characterize the traffic as non-GBR traffic.

(3) Distribution of retention priority (allocation and retention priority, ARP)

The APR value is used to characterize the priority of resource allocation and retention of Evolved Packet System (EPS) bearers in the network. In the network, when a new EPS bearer needs to be established but the resources are insufficient, the access network device may determine whether to remove the original EPS bearer according to the APR value, and establish the new EPS bearer.

It should be noted that the ARP value may be used to characterize the priority of the user (i.e. the terminal device).

The higher the ARP value, the lower the priority of the user. The access network device may divide the user into four classes (e.g., gold, silver, copper, iron) based on the ARP value.

For example, table 3 below shows the ARP value ranges corresponding to the four classes of users.

As shown in table 3, ARP values for gold grade users are in the range of 0-5. The ARP value of silver rated users is in the range of 6-10. The ARP value of copper rated users is in the range of 11-12. The ARP value of the iron grade user is in the range of 13-15.

TABLE 3 Table 3

User rating	ARP value
		Gold medal	1～5
Silver plate	6～10
		Copper plate	11～12
Iron plate	13～15

It should be noted that the ARP value may also be used to characterize whether the user's traffic can be preempted. If preemption vulnerability field in ARP is "pre-emptable", it indicates that the user's traffic can be preempted. If preemption vulnerability field in ARP is "not pre-emptable", it indicates that the user's service can not be preempted.

(4) Releasing traffic

Releasing the service refers to the access network device disconnecting the data transmission of the service.

It should be noted that, after the access network device releases the service, the resources occupied by the service that previously transmitted data are correspondingly released, and the subsequent access network device can normally establish a new service on the resources.

(5) TDD system

The TDD system refers to a system in which transceivers share one radio frequency point, and uplink and downlink use different time slots for communication.

In the current TDD system, different frames need to be allocated to different access network devices to transmit data in order to effectively improve uplink and downlink throughput of the network. In this case, different access network devices are configured with different frames (i.e. the uplink and downlink time-frequency resource configurations are inconsistent), so that serious cross interference exists between different access network devices, and serious influence is caused on data transmission between adjacent access network devices.

(6) Cross interference

Cross interference refers to interference between signals transmitted on uplink timeslots and signals transmitted on downlink timeslots of different access network devices.

The interference between the signal transmitted on the uplink time slot and the signal transmitted on the downlink time slot includes: interference caused by signals transmitted on uplink time slots on signals transmitted on downlink time slots and interference caused by signals transmitted on downlink time slots on signals transmitted on uplink time slots.

The interference caused by the signal transmitted in the uplink time slot to the signal transmitted in the downlink time slot mainly occurs between devices (e.g., terminal devices) on the user plane side. Interference caused by signals transmitted on the downlink time slots to signals transmitted on the uplink time slots occurs mainly between devices on the wireless network side (e.g., access network devices).

For example, as shown in fig. 1, when the terminal 1 accesses the access network device 1 through a communication link and the terminal 2 accesses the base station 2 through a communication link, when the access network device 1 uses a downlink subframe 103 (DL 103 in fig. 1) and the access network device 2 uses an uplink subframe 203 (UL 103 in fig. 1), downlink signals transmitted by the terminal 1 and the access network device 1 will cause interference to uplink signals transmitted by the terminal 2 and the access network device 2, where the interference is cross interference.

It should be noted that there is cross interference between access network devices. I.e. the access network device 1 causes interference to the access network device 2; or the access network device 2 causes interference with the access network device 1.

It should be noted that in the cross interference scenario, there may be adjacent channel interference of resource blocks, interference of other control channels, and interference of broadcast channels between access network devices.

(7) Time-frequency resource

The time-frequency resources include time-domain resources and frequency-domain resources.

The time domain resource refers to a time resource, and may include multiple frames. A frame may include a plurality of time slots, which may include: uplink time slot, downlink time slot, and special time slot.

The frequency domain resource refers to a frequency resource and may include a plurality of carriers. The carrier wave may include: independent carriers and shared carriers.

It should be noted that, the access network device uses a specific time-frequency resource to perform data transmission, that is, the access network device carries service data on a specific frequency domain resource in a specific time domain resource to perform transmission. For example, the access network device carries, in frame 1, data of service B on carrier C for transmission. For another example, the access network device carries data of the service D on the carrier C for transmission within the frame 2.

Traffic data for multiple access network devices may be carried on the same carrier. For example, service data interacted with the terminal device in the access network device 1 and the access network device 2 are both carried on the carrier a.

The timeslot resource configuration of the service data carried by the access network device 1 on the carrier a is as follows: the time slot resources of the frame structure 1 and the service data of the access network device 2 carried on the carrier A are configured as follows: frame structure 2. The structures of the uplink and downlink slots in frame structure 1 and frame structure 2 are shown in table 4.

TABLE 4 Table 4

Where DL denotes a downlink slot and UL denotes an uplink slot.

Illustratively, during transmission, DL12 in frame structure 1 may interfere with UL22 in frame structure 2; DL13 in frame structure 1 may interfere with UL23 in frame structure 2; DL17 in frame structure 1 may interfere with UL27 in frame structure 2.

The foregoing is a simplified description of some of the concepts involved in the embodiments of the present application.

The technical solution of the embodiment of the present application may be applied to various communication systems, for example, the communication system may be a third generation partnership project (3rd generation partnership project,3GPP) communication system, for example, a 5G communication system, an NR internet of vehicles (V2X) system, and other next generation communication systems, and may also be a non-3 GPP communication system, without limitation.

In addition, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and does not constitute a limitation on the technical solution provided in the embodiments of the present application, and as a person of ordinary skill in the art can know, with evolution of network architecture and appearance of a new communication system, the technical solution provided in the embodiments of the present application is applicable to similar technical problems.

In the time division duplex (time division duplexing, TDD) system of the fifth generation (fifth generation, 5G) network, there are diversified network application scenarios. To accommodate a diversified network application scenario, different access network devices may be configured with different frame structures.

If different frame structures are configured between two adjacent access network devices, a downlink time slot of one access network device (denoted as access network device 1) will cause interference to an uplink time slot of another adjacent access network device (denoted as access network device 2), which will cause interference to the access network device 2 when the access network device 1 uses the downlink time slot to transmit data, and affect the data transmission performance of the service.

In addition, if different frame structures are configured between two adjacent access network devices, there is a possibility that uplink and downlink resource conflicts exist between two adjacent access network devices. For example, when the service #1 accesses the access network device 1 and transmits data in the downlink timeslot 1 of the access network device 1, and when the service #2 accesses the access network device 2 and transmits data in the uplink timeslot 2 of the access network device 2, the transmission signal of the service #1 in the downlink timeslot 1 and the transmission signal of the service #2 in the uplink timeslot 2 collide, and the data transmission performance of the service is also affected.

At present, a processing method for reducing data transmission performance caused by cross interference or uplink and downlink resource conflict between adjacent access network devices mainly comprises the following method 1 and method 2.

Method 1: physical isolation, i.e. increasing the degree of isolation in physical space between two access network devices.

For example, the degree of isolation in physical space between two access network devices may be increased by reducing the overlap of coverage between the two access network devices.

As another example, the physical spatial isolation between two access network devices may be increased by increasing the distance between the two access network devices.

The method 1 has the following problems: increasing the degree of isolation in physical space between two access network devices presents a significant scenario limitation in a particular implementation. For example, method 1 is not applicable in a dense networking scenario.

Determining downlink time slots which possibly interfere with other access network devices between adjacent access network devices according to the frame structures of the adjacent access network devices; and closing the downlink time slot when the interference of the downlink time slot to other access network equipment is large.

The method 2 has the following problems: the adoption of the method 2 can reduce the utilization rate of time-frequency resources of the access network equipment, thereby greatly reducing the downlink capacity of the access network equipment. That is, although the method 2 can reduce the influence of the data transmission caused by the cross interference to a certain extent, the method 2 greatly reduces the utilization rate of the time-frequency resource of the access network device, and also affects the transmission performance of the access network device to a certain extent.

In order to solve the problem of reduced data transmission performance caused by cross interference in the prior art, the embodiment of the application provides a resource allocation method, which can effectively improve the transmission performance of access network equipment. As shown in fig. 4, the method includes:

S401, the first access network equipment acquires service information of at least one service.

Wherein the service information includes at least one of: home operator information, service type.

The home operator information may be determined based on public land mobile network (public land mobile network, PLMN) information. The first access network device may obtain PLMN information from a system information block (system information block, SIB) 1.

The service types in the above service information may be classified into a public network type service and a private network type service. Wherein, the public network type service refers to a service carried on a public network; private network type services refer to services carried on a private network.

In one possible implementation, the first access network device may determine a service type of each service according to a data network name (data network name, DNN) corresponding to each service.

Specifically, the first access network device obtains DNN corresponding to each service from the protocol data unit session establishment request (i.e. PDU session establishment request). And then the first access network equipment determines the service type of each service according to the DNN corresponding to each service.

In yet another possible implementation, the first access network device may determine a service type for each service based on an access point name (access point name, APN) for each service.

It should be noted that at least one service is all or part of services of a plurality of terminal devices accessing the first access network device.

An example is that there are 5 terminal devices accessing the first access network device (terminal device D1, terminal device D2, terminal device D3, terminal device D4, and terminal device D5, respectively). There are 3 services of the terminal device D1. There are 2 services of the terminal device D2. There are 1 traffic of the terminal device D3. There are 5 services of the terminal device D4. There are 4 services of the terminal device D5.

In case the at least one service is all services of a plurality of terminal devices accessing the first access network device, the at least one service may comprise 3+2+1+5+4=15 services (i.e. all services of the above 5 terminal devices).

In case the at least one service is part of a plurality of terminal devices accessing the first access network device, the at least one service may comprise 10 of the above 15 services, namely 2 services of terminal device D1, 2 services of terminal device D2, 1 service of terminal device D3, 3 services of terminal device D4, and 2 services of terminal device D5.

It should be noted that the plurality of terminals may be all or part of the terminal devices accessing the first access network device. The plurality of terminal devices specifically includes which terminal devices may be set by the first access network device according to actual situations, which is not limited by the present application.

It should be noted that, the first access network device may be an access network device that is subject to interference, or may be an access network device that emits interference, which is not limited in the present application. For example, the first access network device may be the access network device 1 in fig. 1 (i.e. the interfering access network device). As another example, the first access network device may be the access network device 2 in fig. 1 (i.e. an access network device that is subject to interference).

S402, the first access network equipment determines at least one first service from at least one service according to the service information.

In one possible implementation manner, the first service is a service with the same service information in at least one service.

When the parameters in the service information are different, the first service determined by the first access network device is also different. The parameters in the service information can be specifically divided into the following scenarios: scenario 1, the service information only includes home operator information. Scenario 2, service information includes only the service type. Scenario 3, the service information includes both home operator information and service type. Scenario 1, scenario 2, and scenario 3 are described below, respectively:

Scenario 1, the service information only includes home operator information.

In this scenario, the first access network device determines that a service having the same operator information is a first service.

An example, home operator to which the present application relates, includes operator a, operator B, and operator C.

After the first access network device obtains the home operator information of each service in at least one service, the first access network device determines the service with the operator A as a first service; the first access network equipment determines the service with the operator B as another first service; the first access network equipment determines the service with the operator C as another first service; the first access network device determines a service having an operator a, an operator B, and an operator C as another first service.

Scenario 2, service information includes only the service type.

In this scenario, the first access network device determines that a service having the same service type is a first service.

The service types related to the application comprise public network service A and private network service B.

After the first access network device obtains the service type of each service in at least one service, the first access network device determines the service with the public network service A as a first service; the first access network equipment determines the service with the public network service B as another first service; the first access network equipment determines the service with the public network service A and the public network service B as another first service.

Scenario 3, the service information includes both home operator information and service type.

In this scenario, the first access network device determines that the service having the home operator information and the service type is the first service.

An example, the home operator related to the application comprises an operator A, an operator B and an operator C, and the service types related to the application comprise a public network service D and a private network service E.

After the first access network equipment acquires the home operator information and the service type of each service in at least one service, the first access network equipment determines that the service of an operator A and a public network service D is a first service; the first access network equipment determines the service with the operator B and the public network service D as another first service; the first access network equipment determines the service with the operator C and the public network service D as another first service; the first access network equipment determines the service with the operator A and the public network service E as another first service; the first access network equipment determines the service with the operator B and the public network service E as another first service; the first access network device determines that the service with the operator C and the public network service E is another first service.

S403, the first access network equipment determines the service quality parameter of at least one first service.

Wherein the quality of service parameter comprises at least one of: the service guarantee rate, the priority level value of the service, and the priority value of the user to which the service belongs.

The service guarantee rate is used to characterize the service's requirements for data transmission rate. The first access network device may obtain the service guarantee rate from the core network side.

The priority level value of the service is used to represent the priority of service resource scheduling. The smaller the priority level value, the higher the priority of the resource scheduling of the service. The first access network device may obtain a priority level value from 5QI (i.e., the default priority level in 5QI (Default Priority Level)).

The priority value of the belonging user of a service is used to characterize the priority of the user supporting the service. The priority value of the subscriber to which the service belongs can be represented by an ARP value. The smaller the ARP value, the higher the priority of the user supporting the service.

S404, the first access network device determines an access priority parameter of each first service according to the service quality parameter of each first service in at least one first service.

The access priority parameter is used to characterize the priority of time-frequency resources allocated for the first service.

In one possible implementation, the access priority parameter may satisfy the following equation 1:

Wherein i is the i first service of the at least one first service; ap _i is an access priority parameter of the ith first service; g _i is the rate guarantee factor of the ith first service; pl _i is the priority level value of the ith first service; arp _i is the priority value of the user to which the ith first service belongs; k is the highest value of the priority values of the users to which the service belongs; wherein i is a positive integer, and K is a positive integer.

It should be noted that the rate guarantee factor requires that the first access network device determines according to the service guarantee rate. The specific determination method can refer to the following formula 2, and is not described herein.

In one possible implementation, the rate guarantee factor G _i may satisfy the following equation 2:

wherein, gbr _i ith service guarantee rate of the first service.

It should be noted that, there is a service guarantee rate for GBR service. And the non-GBR service does not have a service guarantee rate, so the first access network equipment sets the service guarantee rate of the non-GBR service to a fixed value for calculating the rate guarantee factor of the non-GBR service. For example, the service provisioning rate of non-GBR service is set to 1.

S405, the first access network equipment determines interference-free time-frequency resources of the first access network equipment.

The interference-free time-frequency resources of the first access network device are different when in different scenes. Scenario 4 and scenario 5 are described below: scenario 4, first access network device is an interfered access network device. Scene 5, the first access network device is the access network device which sends out interference.

Scenario 4, first access network device is an interfered access network device.

In this scenario, the interference-free time-frequency resource of the first access network device is a time-frequency resource that is not interfered by the second access network device in the time-frequency resources of the first access network device.

Scene 5, the first access network device is the access network device which sends out interference.

In this scenario, the interference-free time-frequency resource of the first access network device may also be a time-frequency resource that does not cause interference to the time-frequency resource of the second access network device in the time-frequency resources of the first access network device.

S406, the first access network equipment allocates non-interference time-frequency resources for the first service with the access priority parameter meeting the preset condition.

In one possible implementation manner, the first service meeting the preset condition includes: the first N traffic in the first queue. The first queue is a queue determined by ordering at least one first service according to the access priority parameter. The value of N is determined according to the service number of the interference-free time-frequency resource allocation, and N is a positive integer.

Illustratively, table 5 below is one arrangement of the first queue.

As shown in table 5 below, the first queue includes 7 first services (the 7 first services are M15 and M16 of the terminal device D1, M23 and M24 of the terminal device D2, M31 of the terminal device D3, and M42 and M47 of the terminal device D4, respectively) ordered according to the access priority parameters, and the access priority parameters corresponding to the 7 services, respectively. The access priority parameter of the first service M15 is the highest and the access priority parameter of the first service M47 is the lowest.

In this example, if the first access network device determines that the number of services allocated by the non-interfering time-frequency resource is 5 (i.e., the N value is 5), the first access network device may determine the first 5 first services in the first queue to be the first services that satisfy the preset condition. That is, the first access network device determines M15, M16, M23, M24, M31 as the first service satisfying the preset condition.

TABLE 5

It should be noted that, the specific implementation process of S406 may be: the first access network device firstly ranks at least one first service from big to small according to the time-frequency access priority parameter, and determines a first queue. The first access network equipment sequentially distributes the interference-free time-frequency resources to the first service in the first queue until the interference-free time-frequency resources are distributed.

The steps shown in fig. 4 may be performed in the order of S401, S402, S403, S404, S405, S406, or in the order of S405, S402, S403, S404, S401, S406. The above two sequences are merely two examples of the execution sequence of the steps shown in fig. 4, and other execution sequences of the steps shown in fig. 4 are possible, and the present application is not limited.

The application provides a resource allocation method, a first access network device determines access priority parameters of each first service according to service quality parameters, and then allocates interference-free time-frequency resources to the service with larger access priority parameters (namely important service) preferentially according to the size of the access priority parameters of each first service. Therefore, the service with higher priority of the access network equipment allocates the interference-free time-frequency resource, reduces the influence of cross interference and uplink and downlink resource conflict on the important service, ensures the normal transmission of the important service, and further improves the transmission performance of the access network equipment.

It should be noted that, after the first access network device allocates the interference-free time-frequency resource to the first service in the first queue according to the steps described in S401 to S406, some services not allocated with the interference-free time-frequency resource may still exist in the first queue. The first access network device needs to allocate the interference time-frequency resources to the above-mentioned traffic to which the non-interference time-frequency resources are not allocated.

As shown in fig. 5, the first access network device may allocate the interference time-frequency resources to the traffic to which the non-interference time-frequency resources are not allocated by the following methods S501 to S503.

S501, the first access network equipment determines a second queue.

The second queue is a queue determined after the first access network device orders at least one second service according to the access priority parameter. The second service includes at least one of: and the service of which the interference-free time-frequency resource is not allocated in the at least one first service and the service of which the interference-free time-frequency resource is not allocated in the second access network equipment.

The following describes the procedure of determining the second queue by the first access network device in detail:

step one, the first access network equipment determines that the service which is not allocated with the interference-free time-frequency resource in the first queue is a second service.

And step two, the second access network equipment also determines a third queue according to the similar process described in the steps 401-406. The third queue is a queue determined after the first service in the second access network device is ordered according to the access priority parameter. The second access network device allocates the interference-free time-frequency resources of the second access network device to the first traffic in the third queue. After this, there may be some traffic in the third queue that is not allocated interference free time-frequency resources. The second access network device sends first indication information to the first access network device, and indicates services which are not allocated with interference-free time-frequency resources in the third queues. After the first access network device receives the first indication information, it is determined that the service, which is indicated by the first indication information and is not allocated with the interference-free time-frequency resource, is the second service.

And thirdly, the first access network equipment orders the second service according to the access priority parameters of the second service determined in the first step and the second step, and a second queue is determined.

The second queue and the third queue are exemplarily described below.

Illustratively, table 6 below is a permutation of the third queue.

As shown in table 6 below, the third queue includes 7 first services (N55 and N56 of the terminal device D5, N63 and N64 of the terminal device D6, N71 of the terminal device D7, and N82 and N87 of the terminal device D8, respectively) ordered according to the access priority parameters, and the access priority parameters corresponding to the 7 services, respectively. The access priority parameter of the first service N55 is the highest, and the access priority parameter of the first service N87 is the lowest.

In this example, if the second access network device determines that the number of services allocated by the non-interfering time-frequency resource is 5 (i.e., the N value is 5), the second access network device may determine the first 5 first services in the third queue to be the first services that satisfy the preset condition. That is, the second access network device determines that N55, N56, N63, N64, N71 are the first services satisfying the preset condition.

TABLE 6

It should be noted that, the first service in the first queue and the first service in the third queue have the same service information.

Illustratively, table 7 below is one arrangement of the second queue.

As shown in table 7 below, the second queue includes 7 second services (7 second services are first services (M24, M31, M42, M47), respectively) ordered according to the access priority parameters, and services (N71, N82, N87) of the second access network device to which no interference time-frequency resource is not allocated, and access priority parameters corresponding to the 7 services, respectively. The access priority parameter of the second service M24 is the highest and the access priority parameter of the second service N87 is the lowest.

TABLE 7

S502, the first access network equipment determines an interference time-frequency resource pair.

Wherein, the interference time-frequency resource pair includes: first interfering time-frequency resources of a first access network device and second interfering time-frequency resources of a second access network device.

When a signal transmitted on a downlink time slot of a first access network causes interference to a signal transmitted on an uplink time slot of a second access network device, a first interference time-frequency resource causes interference to a second time-frequency resource. When the signal transmitted on the downlink time slot of the second access network causes interference to the signal transmitted on the uplink time slot of the first access network device, the second time-frequency resource causes interference to the first time-frequency resource.

Illustratively, table 8 below is a plurality of interfering time-frequency resource pairs.

TABLE 8

/>

As shown in table 8 above, the second interfering time-frequency resource DL21 in the pair P1 (i.e. the downlink time-frequency resource DL21 of the second access device) will cause interference to the first interfering time-frequency resource UL11 in the pair P1 (the uplink time-frequency resource UL11 of the first access device). The first interference time-frequency resource DL11 in the P4 (i.e. the downlink time-frequency resource DL11 of the first access device) will cause interference to the second interference time-frequency resource UL21 in the P4 (the uplink time-frequency resource UL21 of the second access device) by the interference time-frequency resource.

In a possible implementation manner, the specific implementation process of S502 may be: the second access network device determines an interfering time-frequency resource (i.e., a second interfering time-frequency resource) of the second access network device and sends second information to the first access network device. The second information is used to indicate second interfering time-frequency resources of the second access network device. The first access network device receives second information from the second access network. The first access network device determines an interference time-frequency resource (i.e., a first interference time-frequency resource) of the first access network device, and then forms an interference time-frequency resource pair from the first interference time-frequency resource and the second interference time-frequency resource.

It should be noted that, the first information and the second information may be combined into one information to be sent by the first access network device, or may be separately sent by the first access network device. The application is not limited in this regard.

S503, the first access network equipment sequentially distributes one of the interference time-frequency resources of the interference time-frequency resource pair to the second service in the second queue according to the arrangement sequence of the services in the second queue.

The time-frequency resource allocated to the second service is the time-frequency resource of the access network equipment corresponding to the second service in the interference time-frequency resource pair.

In combination with table 7 and table 8, the first access network device may allocate the interference resource pair P1 in table 8 to the second service E24 in table 7. As can be seen from table 5, E24 is the first service of the terminal device D2 of the first access network device. Thus, the first access network device allocates the first interference time-frequency resource UL11 in the interference resource pair P1 to the second service E24. In this case, the second interfering time-frequency resource DL21 in the interfering resource pair P1 is not allocated traffic to avoid interference between the first interfering time-frequency resource UL11 and the second interfering time-frequency resource DL 21.

The application provides a resource allocation method, a first access network device determines a second queue and an interference time-frequency resource pair, and allocates one of the interference time-frequency resources of the interference time-frequency resource pair to a second service in the second queue according to an access priority parameter, so that when the second service uses one of the interference time-frequency resources of the interference resource pair, the other interference time-frequency resource does not bear other services, thereby avoiding the problem of mutual interference caused by the simultaneous bearing of the two interference time-frequency resources of the interference time-frequency resource pair, and further improving the transmission performance of the access network device. In addition, when the first access network equipment allocates interference time-frequency resource pairs to the second service in the second queue, interference time-frequency resource pairs are allocated from large to small according to the access priority parameter, so that the access network equipment allocates interference time-frequency resources for the service with higher priority, the service is convenient to carry out data transmission preferentially, and the transmission performance of the access network equipment is further improved.

It should be noted that, the allocation of the interference-free time slot and the allocation of the interference time slot may be performed periodically by the first access network device. The specific execution period may be set by the first access network device according to the actual situation, which is not limited by the present application.

In fig. 4 and fig. 5 above, the process of allocating time-frequency resources for traffic by the first access network device is described.

After the first access network device allocates corresponding time-frequency resources for the first service, the first access network device also needs to determine whether the GRB service in the first service with the allocated time-frequency resources can be accessed to the first access network device according to the satisfaction degree of the service.

As shown in fig. 6, the procedure of the first access network device determining whether the GRB service in the first service with the allocated time-frequency resources can be accessed to the first access network device according to the satisfaction degree of the service may be implemented as follows S601 to S607.

S601, the first access network equipment determines service satisfaction degree of the third service.

The third service is a GRB service in the first service of the allocated time-frequency resource.

The service satisfaction is used for representing the ratio of the actual transmission data quantity of the service to the data quantity to be transmitted of the service.

In one possible implementation, the service satisfaction may satisfy the following equation 3:

Wherein Bs _i is the service satisfaction degree of the ith third service; DA _i is the sum of the actual transmission data amounts of all the services having the same service type as the ith third service in the services accessed to the first access network device; DB _i is the sum of the data amount to be transmitted of all the services having the same service type as the ith third service in the services accessed to the first access network device.

For example, when the first access network device calculates the service satisfaction Bs ₁ of the third service S1, it is necessary to determine the service type of the third service S1 (for example, the service type of the third service S1 is QCI-1), and then determine the service whose service type is also QCI-1 (for example, service #1 and service # 2) from the services already accessed by the first access network device. The first access network device determines the actual transmission data amount and the to-be-transmitted data amount of the service #1 and the service #2, the first access network device determines the sum of the actual transmission data amount and the actual transmission data amount of the service #1 and the service #2, and marks the sum as DA _S1;DB_S1 as the sum of the to-be-transmitted data amount of the service #1 and the to-be-transmitted data amount of the service #2, and then calculates Bs ₁ according to the DA _S1 and the DB _S1.

S602, the first access network device judges whether the service satisfaction degree of the third service is larger than or equal to a preset threshold value.

If the first access network device determines that the service satisfaction degree of the third service is greater than or equal to the preset threshold, the first access network device executes S603.

S603, the first access network device allows the third service to access the first access network device.

It should be noted that, the specific implementation process of S603 may be: the first access network device sends the first indication information to a terminal device (denoted as terminal device D9) corresponding to the third service (third service S2). The first indication information is used for indicating the terminal equipment to access the third service S2 to the first access network equipment. Correspondingly, the terminal device D9 receives the first indication information from the first access network device, generates service establishment request information according to the identifier of the third service S2 carried in the first indication information, and sends the service establishment request information to the first access network device. The service set-up request information is used to request the set-up of the third service S2. Correspondingly, the first access network device receives the service establishment request information from the terminal device D9.

If the first access network device determines that the service satisfaction degree of the third service is smaller than the preset threshold, the first access network device executes S604-S607.

S604, the first access network equipment determines a fourth service according to the priority value of the user to which the service belongs.

Wherein, the priority value of the user to which the fourth service belongs is larger than the priority value of the user to which the third service belongs.

For example, if the priority value of the user to which the third service belongs is 12, the priority value of the user to which the fourth service belongs needs to be greater than 12.

The fourth service is a service with a characteristic of allowing release and preemption in the third service accessed to the first access network equipment.

It should be noted that, even in the case where the priority value of the user to which the service belongs is greater than the priority value of the user to which the third service belongs, if the service needs to have no characteristics of allowing release and allowing preemption, the first access network device cannot perform the operation of releasing the service.

S605, the first access network device determines the number of physical resource blocks (physical resource block, PRBs) of the third service and the fourth service.

S606, the first access network device judges whether the PRB number of the fourth service is greater than or equal to the PRB number of the third service.

If the first access network device determines that the number of PRBs of the fourth service is greater than or equal to the number of PRBs of the third service, the first access network device executes S607.

S607, the first access network device releases the fourth service and allows the third service to access the first access network device.

It should be noted that, the specific implementation process of S607 may be: the first access network device sends the second indication information to the terminal device (denoted as terminal device D10) corresponding to the third service (third service S3). The second indication information is used to instruct the terminal device to stop the data transmission of the third service S2. Correspondingly, after receiving the second indication information from the first access network device, the terminal device _D3 sends third indication information to the first access network device. The third indication information is used to indicate that the terminal device has stopped the data transmission of the third service S3. Correspondingly, after receiving the third indication information from the terminal device D10, the first access network device sends the first indication information to the terminal device D10. The first indication information is used to characterize that the third service S3 is allowed to access the first access network device. Correspondingly, the terminal device D10 receives the first indication information from the first access network device, generates service establishment request information according to the identifier of the third service S3 carried in the first indication information, and sends the service establishment request information to the first access network device. The service set-up request information is used to request the set-up of the third service S3. Correspondingly, the first access network device receives the service establishment request information from the terminal device D10.

If the first access network device determines that the number of PRBs of the fourth service is smaller than the number of PRBs of the third service, the first access network device executes S608.

And S608, the first access network equipment refuses the third service to access the first access network equipment.

It should be noted that, the specific implementation process of S608 may be: the first access network device sends third indication information to the terminal device (denoted as terminal device D11) corresponding to the third service (third service S4). The third indication information is used for indicating the terminal equipment to reject the third service S4 to access the first access network equipment. Correspondingly, the terminal device D11 receives the third indication information from the first access network device.

The application provides a resource allocation method, a first access network device determines whether to allow access to a third service by judging whether the service satisfaction degree of the third service is larger than or equal to a preset threshold value, so that the normal access of the third service is allowed only under the condition that the time-frequency resource of the first access network device can meet the service satisfaction degree of the third service, and the situation that new service is blindly accessed under the condition that the time-frequency resource of the first access network device is congested is avoided, so that the transmission performance of the newly accessed service is reduced, and the transmission performance of the service is further ensured.

In addition, for the third service with service satisfaction less than the preset threshold, the service of the third service which can preempt the time-frequency resource can be determined according to the priority value and PRB number of the user to which the service belongs, so that the service with high priority value of the user to which the service belongs can be preferentially allowed to be accessed, and the transmission performance of the service with high priority value of the user to which the service belongs is further ensured.

Before the first access network device allocates time-frequency resources for the service, a second access network device which has cross interference with the time-frequency resources of the first access network device is also required to be determined in the access network device set with adjacent relation.

As shown in fig. 7, the procedure of determining, by the first access network device, the second access network device among the set of access network devices having the adjacency relationship may be implemented by the following S701 to S705.

S701, the first access network equipment acquires uplink and downlink resource configuration information of all the access network equipment with adjacent relation in the target area in each carrier.

The uplink and downlink resource configuration information comprises at least one of the following items: parameter set (numerology) parameters, subframe type, slot information, subframe to slot relationship, subframe to minislot relationship, slot to minislot relationship, empty resource information, resource configuration information, frame structure, carrier information, pattern index number, dynamic resource information, and fixed resource information. The foregoing is merely an exemplary description of the uplink and downlink resource configuration information, and the uplink and downlink resource configuration information may further include other information, which is not limited in any way by the present application.

It should be noted that the above various information can be obtained through various channels. The plurality of information may include at least one of: broadcast channels, control channels, traffic channels, and access channels. The above-described various channels are merely exemplary, and the above-described various channels may also include other channels, and the present application is not limited in any way.

It should be noted that the access network devices having the adjacency relationship refer to access network devices having a distance between the access network devices smaller than a preset value.

Or the access network devices with adjacent relation refer to the access network devices with the distance between the access network devices smaller than a preset value and the coverage directions of the sectors of the access network devices facing the same direction.

S702, the first access network equipment determines a target carrier.

The target carrier is any one of at least one carrier borne by the first access device.

For example, if the first access network device may carry two carriers (i.e., carrier a and carrier B), in this case, the first access network device may determine that carrier a is the target carrier or that carrier B is the target carrier.

S703, the first access network equipment determines a set of target access network equipment from all access network equipment with adjacent relations in the acquired target area.

The target access network device is an access network device supporting a target carrier.

S704, the first access network device determines uplink and downlink resource configuration information of each target access network device in the set of target access network devices.

S705, the first access network device determines a second access network device from the set of target access network devices.

The second access network device is an access network device having interference with the first access network device.

Illustratively, the first access network device determines a frame structure (frame A1) of a target carrier (carrier a) of the first access network device according to the uplink and downlink resource configuration information. The first access network device determines a frame structure (frame A2) of a target carrier (carrier a) of the target access network device according to the uplink and downlink resource configuration information. As can be seen from the following table 9, the value of the uplink time slot of the frame A1 is 4, and the value of the downlink time slot is 6; the value of the uplink slot of frame A2 is 7 and the value of the downlink slot is 3. In this case, the first access network device may determine that 3 uplink timeslots in frame A2 will be interfered by 3 downlink timeslots in frame A1 (i.e., downlink timeslot DL12 will interfere with uplink timeslot UL22, downlink timeslot DL13 will interfere with uplink timeslot UL23, and downlink timeslot DL17 will interfere with uplink timeslot UL 27), so that the first access network device determines that the target access network device is the second access network device.

TABLE 9

When the first access network device determines that the number of the second target access network devices is plural, the second target access network devices are sequentially allocated according to the above actions.

The application provides a resource allocation method, a first access network device determines a second access network device with interference in a plurality of adjacent access network devices in a designated area according to uplink and downlink configuration information. In this case, not only the interference-free time-frequency resource of the first access network device is preferentially allocated to the service with the larger access priority parameter, but also the interference-free time-frequency resource of the second access network device is preferentially allocated to the service with the larger access priority parameter, and the interference-free time-frequency resource is allocated to the service which is not allocated to the interference-free time-frequency resource in the first access network device and the second access network device in the form of resource pairs, so that the service which is not allocated to the interference-free time-frequency resource in the first access network device and the second access network device uses only one resource in the interference-free time-frequency resource pair for data transmission, thereby effectively improving the transmission performance of the access network device.

It should be noted that the above embodiments are described by taking the first access network device as an example. In an actual process, the second access network device may also allocate non-interference time-frequency resources and/or interference time-frequency resources for the service in the second access device by executing S401-S401 in fig. 4, S501-S503 in fig. 5, S601-S607 in fig. 6, and S701-S705 in fig. 7.
