In a Time Division Duplex (TDD) system of a fifth generation (5G) network, there are diversified network application scenarios. In order to adapt to diversified network application scenarios, different access network devices may configure 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) may cause interference to an uplink time slot of another adjacent access network device (denoted as access network device 2), which may cause interference to the access network device 2 when the access network device 1 transmits data using the downlink time slot, and affect the uplink transmission performance of the access network device 2.

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

Hereinafter, terms related to the embodiments of the present application are explained for the convenience of the reader.

(1) Co-construction sharing

The co-establishment sharing refers to a network establishment scheme for sharing carrier resources among different operators. Through co-construction and sharing, one access network device can bear services of a plurality of operators, or one access network device can bear a plurality of types of services, so that the network construction cost of the operators is reduced.

The co-construction sharing comprises the following steps: independent carrier sharing, carrier-level shared carrier sharing, service 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 equipment configures a separate carrier C for type B traffic of operator a.

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

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

Under the application scene of unlimited-level sharing of shared carriers, the access network equipment configures one shared carrier for multiple types of services of multiple operators. For example, the access network device configures a shared carrier M for type J, type Q, and type L services 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 increased, the coverage area of the access network device is correspondingly reduced, and the number of the access network devices to be deployed for covering the same area is continuously increased. In addition, the current access network devices usually adopt Multiple In Multiple Out (MIMO) technology, and the number of antennas of the access network devices is greatly increased, 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 for network construction of the operator is also greatly increased. The co-construction sharing network construction scheme can well solve the problem that the network construction cost of an operator is increased due to the increase of access network equipment at present.

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

The 5QI is used to indicate the traffic characteristics of different traffic in the 5G network. For example, traffic characteristics of Guaranteed Bit Rate (GBR) traffic, and traffic characteristics of non-guaranteed bit rate (non-GBR) traffic. In a fourth generation (4G) network, the service characteristics of different services may be represented by quality of service (QCI) identifiers.

It should be noted that the 5QI may be acquired through session management function-unified data management function 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 PDU 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, and may also be used to characterize the service characteristics of one service (which may be multiple services).

As an example, table 1 below is a 5QI for various types of GBR traffic.

As shown in table 1, the 5QI may include at least one of: a 5QI Value (5QI Value), a Default Priority Level (Default Priority Level), a Packet Delay Budget (Packet Delay Budget), a Packet Error Rate (Packet Error Rate), a Default Averaging Window (Default Averaging Window), and typical Services (Example Services).

TABLE 1

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

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

TABLE 2

It should be noted that a 5QI Value (i.e. 5QI Value) in 5QI can be used to distinguish between GBR traffic and non-GBR traffic. For example, when the 5QI value is 1, 2, 3, 4, 65, 66, 67, it can 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) Allocation and Retention Priority (ARP)

The APR value is used to characterize the priority of resource allocation and maintenance of an Evolved Packet System (EPS) bearer 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).

A higher ARP value indicates a lower priority for the user. The access network device may classify the users into four classes (e.g., gold, silver, copper, iron) based on the ARP value.

For example, the following table 3 shows ranges of ARP values respectively corresponding to the above-mentioned four levels of users.

As shown in Table 3, the ARP values for gold-rated users ranged from 0 to 5. The ARP value of silver-rated users is in the range of 6-10. The ARP value for copper class users is in the range of 11-12. The ARP value for iron grade users is in the range of 13-15.

TABLE 3

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

It should be noted that the ARP value may also be used to indicate whether the service of the user can be preempted. If the preemption virtualization field in ARP is "pre-empty", it indicates that the user's service can be preempted. If the prediction virtualization field in ARP is ' not pre-empty ', it indicates that the user's service can not be preempted.

(4) Releasing traffic

Releasing the service means that the access network device disconnects the data transmission of the service.

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

(5) TDD system

The TDD system is a system in which a radio frequency point is shared for transceiving and different time slots are used for uplink and downlink communications.

It should be noted that, in the current TDD system, in order to effectively improve the uplink and downlink throughput of the network, different frames need to be allocated to different access network devices to transmit data. In this case, different access network devices configure different frames (i.e., the uplink and downlink time-frequency resource configurations are inconsistent), so that there is severe cross interference between different access network devices, which may cause severe impact on data transmission between adjacent access network devices.

(6) Cross interference

Cross interference refers to interference between signals transmitted on uplink time slots and signals transmitted on downlink time slots 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 the uplink time slot to signals transmitted on the downlink time slot, and interference caused by signals transmitted on the downlink time slot to signals transmitted on the uplink time slot.

It should be noted that interference caused by a signal transmitted on an uplink time slot to a signal transmitted on a 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 mainly occurs between devices (e.g., access network devices) on the radio network side.

For example, as shown in fig. 1, a terminal 1 accesses an access network device 1 through a communication link, and a terminal 2 accesses a base station 2 through the communication link, when the access network device 1 currently uses a downlink subframe 103 (denoted as DL103 in fig. 1) and the access network device 2 currently uses an uplink subframe 203 (denoted as UL103 in fig. 1), a downlink signal transmitted by the terminal 1 and the access network device 1 may cause interference to an uplink signal transmitted by the terminal 2 and the access network device 2, where the interference is cross interference.

It should be noted that cross interference exists between access network devices. Namely, the access network device 1 causes interference to the access network device 2; alternatively, the access network device 2 causes interference to the access network device 1.

It should be noted that, in the scenario of cross interference, there may also 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 a plurality of frames. One frame may include a plurality of slots, and the plurality of slots may include: an uplink time slot, a downlink time slot, and a special time slot.

The frequency domain resources refer to frequency resources and may include a variety of carriers. The carrier may include: an independent carrier and a shared carrier.

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

The service data of multiple access network devices may be carried on the same carrier. For example, service data interacted between the access network device 1 and the access network device 2 and the terminal device are both carried on the carrier a.

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

TABLE 4

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

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

The above is a brief introduction to some of the concepts involved in the embodiments of the present application.

The technical solution of the embodiment of the present application can be applied to various communication systems, for example, the communication system can be a third generation partnership project (3 GPP) communication system, such as a 5G communication system, an NR vehicle-to-electronic (V2X) system, and other next-generation communication systems, and can also be a non-3 GPP communication system, which is not limited.

Acts, terms, etc. referred to between the embodiments of the present application may be mutually referenced and are not limiting. In the embodiment of the present application, the name of the message exchanged between the devices or the name of the parameter in the message, etc. are only an example, and other names may also be used in the specific implementation, which is not limited.

In addition, the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and it is known by a person of ordinary skill in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems with the evolution of network architecture and the appearance of new communication systems.

In a Time Division Duplex (TDD) system of a fifth generation (5G) network, there are diversified network application scenarios. In order to adapt to diversified network application scenarios, different access network devices may configure 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) may cause interference to an uplink time slot of another adjacent access network device (denoted as access network device 2), which may cause interference to the access network device 2 when the access network device 1 transmits data using the downlink time slot, and affect data transmission performance of a 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 may exist between the two adjacent access network devices. For example, if the service #1 accesses the access network device 1 and transmits data in the downlink time slot 1 of the access network device 1, and at this time, the service #2 accesses the access network device 2 and transmits data in the uplink time slot 2 of the access network device 2, a collision may occur between a transmission signal of the service #1 in the downlink time slot 1 and a transmission signal of the service #2 in the uplink time slot 2, and the data transmission performance of the service may also be affected.

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

The method comprises the following steps: physical isolation, i.e. increasing the degree of isolation in the 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 coverage overlap between the two access network devices.

As another example, the degree of separation in physical space between two access network devices may be increased by increasing the distance between the two access network devices.

Problems with method 1: increasing the degree of isolation in physical space between two access network devices has significant scenario limitations in the implementation. For example, method 1 cannot be applied in a dense networking scenario.

The method 2, according to the frame structure of the adjacent access network equipment, determining the downlink time slot which may interfere with other access network equipment between the adjacent access network equipment; and when the interference of the downlink time slot to other access network equipment is large, closing the downlink time slot.

Problems with method 2: by adopting the method 2, the utilization rate of time-frequency resources of the access network equipment can be reduced, and further the downlink capacity of the access network equipment is greatly reduced. That is to say, although the method 2 can mitigate the influence of data transmission caused by cross interference to some extent, the method 2 can greatly reduce the utilization rate of the time-frequency resource of the access network device, and also influence the transmission performance of the access network device to some extent.

In order to solve the problem of data transmission performance reduction caused by cross interference in the prior art, the embodiment of the present 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 obtains service information of at least one service.

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

The home operator information may be determined based on Public Land Mobile Network (PLMN) information. The first access network device may obtain PLMN information from a System Information Block (SIB) 1.

The service types in the service information can be classified into public network type services and private network type services. The public network type service refers to a service carried on a public network; private network type traffic refers to traffic carried over a private network.

In a possible implementation manner, the first access network device may determine the service type of each service according to a Data Network Name (DNN) corresponding to each service.

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

In another possible implementation manner, the first access network device may determine the service type of each service according to an Access Point Name (APN) of each service.

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

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

In the case that 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 include 15 services (i.e., all services of the above 5 terminal devices).

In the case that the at least one service is a partial service of a plurality of terminal devices accessing the first access network device, the at least one service may include 10 services of the above 15 services, that is, 2 services of the terminal device D1, 2 services of the terminal device D2, 1 service of the terminal device D3, 3 services of the terminal device D4, and 2 services of the 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 include which terminal devices can be set by the first access network device according to an actual situation, which is not limited in the present application.

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

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

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 may be specifically classified into the following scenarios: scenario 1, the service information only includes home operator information. Scenario 2, the service information includes only the service type. Scenario 3, the service information includes both home operator information and service type. Scene 1, scene 2, and scene 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 the services with the same operator information are the first services.

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

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

Scenario 2, the service information includes only the service type.

In this scenario, the first access network device determines that the services with the same service type are the first services.

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

After the first access network equipment acquires the service type of each service in at least one service, the first access network equipment determines that the service with the public network service A is a first service; the first access network equipment determines that the service with the public network service B is another first service; the first access network equipment determines that the service with the public network service A and the public network service B is the other 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.

In an example, the home operator related to the present application includes an operator a, an operator B, and an operator C, and the service types related to the present application include a public network service D and a private network service E.

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

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

The service guarantee rate is used for representing the requirement of the service on the data transmission rate. The first access network device may obtain the service guarantee rate from the core network side.

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

The priority value of the user to which the service belongs is used for representing the priority of the user supporting the service. The priority value of the user 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 equipment 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 for representing the priority degree of time frequency resource allocation for the first service.

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

wherein, i is the ith first service in at least one first service; ap (Ap)_iAn access priority parameter for the ith first service; g_iA rate guarantee factor for the ith first service; pl_iThe priority value of the ith first service is the priority value of the ith first service; arp_iThe priority value of the user to which the ith first service belongs; k is the highest value of the priority value of the user to which the service belongs; wherein i is a positive integer and K is a positive number.

It should be noted that the rate guarantee factor needs to be determined by the first access network device according to the service guarantee rate. For a specific determination, the following formula 2 can be referred to, and details are not repeated here.

In a possible implementation, the rate guarantee factor G_iThe following equation 2 may be satisfied:

wherein, Gbr_iAnd the service guarantee rate of the ith first service.

It should be noted that there is a service guarantee rate for the GBR service. And the non-GBR service has no service guarantee rate, so the first access network equipment sets the service guarantee rate of the non-GBR service as a fixed value in order to calculate the rate guarantee factor of the non-GBR service. For example, the service guaranteed rate of non-GBR traffic is set to 1.

S405, the first access network equipment determines the non-interference time-frequency resource of the first access network equipment.

And under different scenes, the interference-free time-frequency resources of the first access network equipment are different. Scene 4 and scene 5 are described below, respectively: and in the scenario 4, the first access network device is an interfered access network device. And in the scene 5, the first access network device is an access network device which emits interference.

And in the scenario 4, the first access network device is an interfered access network device.

In this scenario, the non-interference 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.

And in the scene 5, the first access network device is an access network device which emits interference.

In this scenario, the non-interference 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 device allocates non-interference time-frequency resources for the first service with the access priority parameter meeting the preset condition.

In a possible implementation manner, the first service meeting the preset condition includes: the first N services in the first queue. The first queue is a queue determined by ordering the at least one first service according to the access priority parameter. The value of N is determined according to the number of services distributed by the non-interference time-frequency resources, 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) sorted 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-interference time-frequency resource is 5 (that is, the value of N is 5), the first 5 first services in the first queue may be determined as the first services meeting the preset condition by the first access network device. That is, the first access network device determines that M15, M16, M23, M24, M31 are the first traffic satisfying the preset condition.

TABLE 5

It should be noted that, the specific implementation process of S406 may be: the first access network equipment arranges at least one first service from big to small according to the time-frequency access priority parameter, and determines a first queue. And the first access network equipment sequentially allocates the non-interference time-frequency resources to the first service in the first queue until the non-interference time-frequency resources are allocated completely.

Note that the execution order of the steps shown in fig. 4 may be S401 → S402 → S403 → S404 → S405 → S406, or S405 → S402 → S403 → S404 → S401 → S406. The above two sequences are only two examples of the execution sequence of the steps shown in fig. 4, and the steps shown in fig. 4 may also have other execution sequences, which is not limited in this application.

The application provides a resource allocation method, wherein first access network equipment determines an access priority parameter of each first service according to a service quality parameter, and then allocates interference-free time-frequency resources to services with larger access priority parameters (namely more important services) preferentially according to the size of the access priority parameter of each first service. Therefore, the service with higher priority of the access network equipment allocates the non-interference time-frequency resource, thereby reducing the influence of cross interference and uplink and downlink resource conflict on the important service, ensuring the normal transmission of the important service and further improving the transmission performance of the access network equipment.

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

As shown in fig. 5, the first access network device may allocate interference time-frequency resources to the services to which no interference-free time-frequency resources are allocated by the following methods described in S501 to S503.

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

The second queue is determined after the first access network device sorts at least one second service according to the access priority parameter. The second service includes at least one of: at least one service without interference-free time frequency resource is not allocated in the first service, and a service without interference-free time frequency resource is not allocated in the second access network equipment.

The following describes a process of determining the second queue by the first access network device:

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

Step two, the second access network device also determines the third queue according to the similar process described in the above S401-S406. The third queue is determined after the first service in the second access network equipment is sequenced according to the access priority parameter. And the second access network equipment allocates the non-interference time-frequency resource of the second access network equipment to the first service in the third queue. After that, there may be some traffic in the third queue that is not allocated interference-free time-frequency resources. And the second access network equipment sends first indication information to the first access network equipment to indicate the services which are not allocated with the 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 also the second service.

And step three, the first access network equipment sorts the second service according to the access priority parameter of the second service determined in the step one and the step two, and determines a second queue.

The second queue and the third queue are exemplified below.

Illustratively, Table 6 below is one arrangement of the third queue.

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

In this example, if the second access network device determines that the number of services allocated by the non-interference time-frequency resource is 5 (that is, the value of N is 5), the second access network device may determine that the first 5 first services in the third queue are the first services meeting the preset condition. That is, the second access network device determines N55, N56, N63, N64, N71 as the first service 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 (the 7 second services are the first services (M24, M31, M42, M47)) sorted according to the access priority parameters, services (N71, N82, N87) of the second access network device to which no interference-free time-frequency resources are 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 interference time-frequency resource pairs.

Wherein, the interference time-frequency resource pair includes: a first interference time-frequency resource of the first access network device, and a second interference time-frequency resource of the 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 second access network equipment, the first interference time-frequency resource causes interference to the 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 interference time-frequency resource pairs.

TABLE 8

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

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

It should be noted that the first information and the second information may be combined into one information by the first access network device and transmitted, or may be separately transmitted by the first access network device. This is not a limitation of the present application.

S503, the first access network device sequentially allocates one of the interference time-frequency resource pairs 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 device corresponding to the second service in the interference time frequency resource pair.

In conjunction with table 7 and table 8 above, for example, the first access network device may assign the pair of interference resources P1 in table 8 to the second service E24 in table 7. As can be seen from table 5, E24 is the first traffic of the terminal device D2 of the first access network device. Therefore, the first access network device allocates the interference resource pair P1 with the first interference time-frequency resource UL11 to the second service E24. In this case, no traffic is allocated to the second interfering time-frequency resource DL21 in P1 for the interfering resource pair to avoid interference between the first interfering time-frequency resource UL11 and the second interfering time-frequency resource DL 21.

The first access network equipment firstly determines a second queue and an interference time-frequency resource pair, and then allocates one 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 resource pair, the other interference time-frequency resource does not bear other services, the problem that the two interference time-frequency resources in the interference time-frequency resource pair bear services simultaneously to cause mutual interference is further avoided, and the transmission performance of the access network equipment can be further improved. In addition, when the first access network equipment allocates the interference time-frequency resource pairs to the second service in the second queue, the interference time-frequency resource pairs are also allocated according to the access priority parameters from large to small, so that the interference time-frequency resources are allocated to the service with higher priority of the access network equipment, the service with higher priority of the access network equipment is convenient to preferentially transmit data, and the transmission performance of the access network equipment is further improved.

It should be noted that the allocation of the non-interference timeslot and the allocation of the interference timeslot 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 an actual situation, which is not limited in this application.

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

After the first access network device allocates the corresponding time-frequency resource to the first service, the first access network device further needs to determine whether the GRB service in the first service allocated with the time-frequency resource can access the first access network device according to the satisfaction degree of the service.

As shown in fig. 6, the process that the first access network device determines whether the GRB service in the first service of the allocated time-frequency resource can access the first access network device according to the service satisfaction may be implemented through the following steps S601 to S607.

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

And the third service is the GRB service in the first service which is allocated with the time-frequency resource.

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

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

wherein, Bs_iThe service satisfaction degree of the ith third service is obtained; DA_iThe total sum of actual transmission data volumes of all services with the same service type as the ith third service in the services accessed to the first access network equipment; DB_iFor all the services having the same service type as the ith third service among the services accessed to the first access network equipmentThe sum of the amounts of data to be transmitted.

Illustratively, the service satisfaction degree Bs of the third service S1 is calculated at the first access network device₁In time, 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 services (for example, service #1 and service #2) with the same service type as QCI-1 from the services that the first access network device has accessed. The first access network equipment determines the actual transmission data volume and the data volume to be transmitted of the service #1 and the service #2, and the first access network equipment determines the sum of the actual data volume of the service #1 and the actual transmission data volume of the service #2 and records the sum as DA_S1；DB_S1Is the sum of the data volume to be transmitted of the service #1 and the data volume to be transmitted of the service #2, and further according to the DA_S1And the above DB_S1Calculating to obtain Bs₁。

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

If the first access network device determines that the service satisfaction 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 the terminal device (denoted as terminal device D9) corresponding to the third service (third service S2). The first indication information is used to instruct the terminal device to access the third service S2 to the first access network device. 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 establishment request information is used to request establishment of the third service S2. Accordingly, 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 of the third service is less 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.

And the priority value of the user to which the fourth service belongs is greater than that of the user to which the third service belongs.

Illustratively, 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 the characteristics of allowing release and allowing preemption in the third service which has accessed to the first access network equipment.

It should be noted that, even when 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 the characteristics of allowing release and allowing preemption, the first access network device cannot release the service.

S605, the first access network device determines the Physical Resource Block (PRB) numbers of the third service and the fourth service.

S606, the first access network equipment judges whether the PRB number of the fourth service is larger 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: and the first access network device sends the second indication information to the terminal device (marked 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. Accordingly, the terminal device_D3And after receiving the second indication information from the first access network equipment, sending third indication information to the first access network equipment. The third indication information is used to indicate that the terminal device has stopped the data transmission of the third service S3. Correspondingly, the first access network device receives the third finger from the terminal device D10After the information is displayed, the first indication information is sent to the terminal device D10. The first indication information is used for characterizing 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 establishment request information is used to request establishment of the third service S3. Accordingly, 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 the 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 to instruct the terminal device to reject the third service S4 to access the first access network device. Accordingly, the terminal device D11 receives the third indication information from the first access network device.

The application provides a resource allocation method, wherein a first access network device determines whether to allow access to a third service by judging whether the service satisfaction of the third service is greater than or equal to a preset threshold, 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 of the third service, the situation that the transmission performance of the newly accessed service is reduced due to blind access to the new service under the condition that the time-frequency resource of the first access network device is congested is avoided, and the transmission performance of the service is further ensured.

In addition, for a third service with the service satisfaction degree smaller than the preset threshold, the service of the time-frequency resource can be occupied by the third service according to the priority value of the user to which the service belongs and the number of PRBs (physical resource blocks), so that the service with the 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 the high priority value of the user to which the service belongs is further ensured.

Before the first access network device allocates the time-frequency resources for the service, it is further required to determine, in the set of access network devices having an adjacent relationship, a second access network device that has cross interference with the time-frequency resources of the first access network device.

As shown in fig. 7, the process of the first access network device determining the second access network device in the set of access network devices having the adjacent relationship may be implemented through the following S701 to S705.

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

Wherein, 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-small slot relationship, slot-to-small slot relationship, null resource information, resource configuration information, frame structure, carrier information, pattern index number, dynamic resource information, and fixed resource information. The above 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 this 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: a broadcast channel, a control channel, a traffic channel, and an access channel. The above-mentioned various channels are merely an exemplary illustration, and the above-mentioned various channels may also include other channels, which is not limited in this application.

It should be noted that the access network devices in the adjacent relationship refer to the access network devices whose distance between the access network devices is smaller than a preset value.

Or, the access network devices having an adjacent relationship refer to the access network devices in which the distance between the access network devices is smaller than a preset value and the directions of the coverage directions of the sectors of the access network devices are the same.

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

The target carrier is any one of at least one carrier carried by the first access equipment.

For example, if the first access network device can 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, and may also determine that carrier B is the target carrier.

And S703, the first access network device determines a set of target access network devices from all the obtained access network devices in the target area, wherein the access network devices have an adjacent relationship.

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.

And the second access network equipment is access network equipment which has interference with the first access network equipment.

Illustratively, the first access network device determines a frame structure of a target carrier (carrier a) of the first access network device according to the uplink and downlink resource configuration information (frame a 1). The first access network equipment determines a frame structure (frame A2) of a target carrier (carrier A) of the target access network equipment according to the uplink and downlink resource configuration information. As can be seen from table 9 below, the value of the uplink timeslot in frame a1 is 4, and the value of the downlink timeslot is 6; the value of the uplink timeslot of frame a2 is 7 and the value of the downlink timeslot is 3. In this case, the first access network device may determine that 3 uplink timeslots in frame a2 would be interfered by 3 downlink timeslots in frame a1 (i.e., downlink timeslot DL12 would cause interference to uplink timeslot UL 22; downlink timeslot DL13 would cause interference to uplink timeslot UL 23; downlink timeslot DL17 would cause interference to uplink timeslot UL 27), and thus, the first access network device determines that the target access network device is the second access network device.

TABLE 9

When the number of the second target access network devices determined by the first access network device is plural, the second target access network devices may be sequentially allocated according to the above-described actions.

The application provides a resource allocation method, wherein 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. Under the condition, the non-interference time-frequency resource of the first access network equipment is preferentially distributed to the service with larger access priority parameter, the non-interference time-frequency resource of the second access network equipment is preferentially distributed to the service with larger access priority parameter, and the interference time-frequency resource is also distributed to the service which is not distributed with the non-interference time-frequency resource in the first access network equipment and the second access network equipment in a resource pair mode, so that the service which is not distributed with the non-interference time-frequency resource in the first access network equipment and the second access network equipment only uses one resource in the interference time-frequency resource pair for data transmission, and the transmission performance of the access network equipment can be effectively improved.

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