Description

Resource allocation method and access network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource allocation method and an access network device.

Background

With the continuous evolution of networks, diversified industry application demands have exploded greatly. Network requirements for industry users have become an important deployment requirement for 5G. The fifth generation mobile communication technology (5th-generation, 5G) network provides multiple slicing modes, which can satisfy the demands of both customers (2C) and enterprises (2B). However, the 5G device (5G base station) uses 192-element multi-element antenna devices, and the frequency band used by the 5G device is 3.5GHz, and the coverage range is significantly smaller than that of the device in the frequency band of 2GHz or less, which results in the multiplied number of stations (number of base stations) in a unit area, and thus, the high base station cost and the dense number of stations result in the exponential increase of the network construction cost. Therefore, operators are seeking a solution for co-establishing a base station by multiple operators and performing network deployment by using the co-established base station. The co-building of the base station means that one base station can meet the requirements of multiple operators, and the equipment of the multiple operators is not centralized in the same base station for deployment.

How a shared base station after co-construction supports public network services (2C services) and private network services (2B services) of multiple operators and reasonably distributes resources becomes a problem to be solved urgently.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.

At present, because the single cost of the 5G base station is high, and because the coverage area of the base station is small, the number of sites to be arranged in a unit area is large, and the cost of completing the deployment of the 5G communication network is high. Therefore, at present, a shared base station is co-established by a plurality of operators, so that the service requirements of the plurality of operators can be borne. However, how to satisfy resource allocation of services of different network classes of different operators is an urgent problem to be solved for a co-established shared base station.

In view of the above problems, embodiments of the present application provide a resource allocation method, which can reasonably allocate resources to services with different priorities based on capacity (traffic). The method is applied to the system architecture as shown in fig. 1, and the system may include: a terminal 01, an access network device 02 and at least one core network device 03(03-1, 03-2, 03-3 and 03-4), where each core network device 03 corresponds to an operator core network (a private network core network (supporting 2B services) or a public network core network (supporting 2C services) or other network core networks of possible network types); for example, referring to fig. 1 (taking the example that only the private network corresponding to the 2B service and the public network corresponding to the 2C service exist, 03-1 may correspond to the core network of the public network of the operator a, 03-2 may correspond to the core network of the private network of the operator a, 03-3 may correspond to the core network of the public network of the operator B, and 03-4 may correspond to the core network of the private network of the operator B. After the access network device 02 of the terminal 01 is connected with the access network device, the terminal can access the core network of the public network or the core network of the private network of the corresponding operator through different core network devices 03. Of course, only one core network device 03 may actually exist, and the functions of the above-mentioned multiple core network devices may be completed.

It should be noted that, in the present application, one operator core network corresponds to one public network and a plurality of private networks.

Illustratively, referring to fig. 2, the functional modules in the core network device 03 may include a service distribution requirement collecting module 031, a service dependency analyzing module 032, and a critical traffic customizing module 033. The service distribution requirement collecting module 031 may collect network data of various private networks or public networks of the corresponding operators of the access network device 02 (e.g., a base station) connected thereto. The network data may include: traffic related data of a service corresponding to the network (average capacity/traffic per target unit time (e.g., hour), maximum capacity/traffic per target unit time (e.g., hour)), traffic flow or the number of users, and the like.

The service dependency analysis module 032 may determine, through a certain calculation, whether the service in the actual scene corresponding to the network data mainly depends on the capacity (flow) by using the network data acquired by the corresponding service distribution demand collection module 031 in cooperation with the service dependency analysis module 032 in the other core network device corresponding to the access network device 02 connected thereto. Of course, if all the core networks correspond to the same core network device, the service dependency analysis module included therein independently completes the above calculation process.

The critical traffic customizing module 033 may calculate, through cooperation with the critical traffic customizing modules 033 in other core network devices corresponding to the access network device 02 connected thereto, the agreed capacity (preset unit traffic) per unit time recommended for the public networks and private networks of different operators according to the network data acquired by the respective corresponding service distribution demand collecting module 031. Of course, if all the core networks correspond to the same core network device, the key traffic customization modules included therein independently complete the above calculation process. For example, taking a unit time of 1TTI (transmission time interval) and a target unit time of 1 hour as an example, the preset unit traffic of the public network of a certain operator can be calculated by the following formula:

wherein, T^PU _YIs a predetermined unit flow, T, of the public network of the operator^PU _MaxIs the maximum hourly flow, T, of the operator's public network^PU _meanThe average hourly traffic for the operator's public network.

The preset unit flow of a private network of an operator can be calculated by the following formula:

wherein, T^Pr _YA predetermined unit flow, T, for the private network of the operator^Pr _MaxMaximum hourly traffic, T, for the private network of the operator^Pr _meanThe average hourly traffic for the private network for that operator.

Illustratively, referring to fig. 2, the access network device 02 includes a network parameter collection module 021, a service guarantee parameter collection module 022, a priority parameter calculation module 023, and a user access and resource allocation module 024.

The network parameter collection 021 may collect information such as frequency point information, PLMN information, and DNN information of all services (services to be accessed) that need to access the access network device, so as to identify an operator and a network of each service, and specifically, the collected data may refer to data shown in table 1 below.

Service identification	Frequency point information	Public and private network identification	DNN
				1	A	PU	—
2	B	PU	—
				3	A	Pr	1
4	A	Pr	i
				5	B	Pr	1
n	B	Pr	j

TABLE 1

Wherein, a represents that the service belongs to a carrier of an operator a, B represents that the service belongs to a carrier of an operator B, PU represents that the network type of the service is a public network, Pr represents that the network type of the service is a private network, DNN is 1 represents a private network 1, DNN is i represents a private network i, and DNN is j represents a private network j.

The service assurance parameter collecting module 022 may extract parameters related to service characteristics of a service to be accessed, such as information of a priority level, a service demand flow in a current unit time, service arrival time, service demand duration, and the like, which are provided to the priority parameter calculating module 023 for calculating a service priority parameter, and specifically collected data may refer to the following table 2.

TABLE 2

Taking a 5G communication system as an example, the priority level needs to collect 5QI (5G QoS Identifier) (used to identify QoS (Quality of Service) of 5G), index the 5G QoS characteristics according to the value of 5QI, refer to table 3 for specific contents of mapping standard 5QI to 5G QoS characteristics, and refer to table 4 for meaning of 5G QoS characteristics.

TABLE 3

TABLE 4

The user access and resource allocation module 024 is configured to determine the resource allocation condition of each service to be accessed according to the priority parameter calculated by the priority parameter calculation module 023, the traffic demand flow acquired by the traffic guarantee parameter acquisition module 022, and the preset unit flow of each network obtained by the key flow customization module 033.

Illustratively, taking a 5G communication network as an example, referring to fig. 3, a practical device in the access network device 02 may include a radio frequency unit and a baseband processing unit. The radio frequency unit is connected to the baseband processing unit through a common public radio interface (CPRI (eCRPI)), and a public network core network (5GC1) of the operator a, a public network core network (5GC2) of the operator B, a private network core network (5GC3) of the operator a, and a private network core network (5GC4) of the operator B are connected to the baseband processing unit of the access network device 2 through an NG interface.

The 5G baseband processing unit includes a Control Plane (CP) and a User Plane (UP). The control plane has an identification module (specifically, the identification module can be judged by a PLMN (public land mobile network), an APN (access point name), a DNN (Data network name), and the like) for the private network core network and the public network core network of different operators, so that the public network core network and the private network core network of different operators can be distinguished. The traffic real-time monitoring module 021, the traffic discrimination module 022, and the network load balancing module 023 may also all be disposed in the CP.

The 5G radio frequency unit comprises an antenna unit, a switch and a transceiver. The transceiver includes a Digital Up Conversion (DUC), a digital to analog converter (DAC), a transmission antenna (TX), a reception antenna (RX), an analog to digital converter (ADC), and a Digital Down Conversion (DDC).

Specifically, in the technical scheme provided by the present invention, the access network device 02 configures one carrier for each operator, and each carrier provides support for the public network service and the private network service of the corresponding operator. Each carrier includes an uplink carrier and a downlink carrier, the communication link corresponding to the uplink carrier is composed of the antenna unit, the switch, the RX (RX1 and RX2), the ADC (ADC1 and ADC2), the DDC (DDC1 and DDC2), and the 5G baseband processing unit in fig. 3, and the communication link corresponding to the downlink carrier is composed of the antenna unit, the switch, the TX (TX1 and TX2), the DAC (DAC1 and DAC2), the DUC (DUC1 and DUC2), and the 5G baseband processing unit in fig. 3.

For example, as shown in fig. 3, when 2 operators (operator a and operator B, respectively) are accessed into the access network device, the operator a performs data transmission through the first carrier when initiating a public network service or a private network service, and the user terminal of the operator B performs data transmission through the second carrier when initiating a private network service. Wherein the first carrier comprises a first transceiver (DUC1, DAC1, TX1, DDC1, ADC1, RX1), a first combiner, a switch, and an antenna unit; the second carrier includes a second transceiver (DUC2, DAC2, TX2, DDC2, ADC2, RX2), a second combiner, a switch, and an antenna unit.

Based on the contents shown in fig. 1 to fig. 3, an embodiment of the present application provides a resource allocation method, which is applied to the access network device 02. Referring to FIG. 4, the method includes 401-404:

401. determining the network type of each quasi-access service in at least one quasi-access service corresponding to a target carrier; the target carrier is any one of the multi-path carriers configured by the access network equipment.

Optionally, because the access network device is configured with multiple carriers, before step 401, in order to ensure that step 401 is smoothly implemented, it is necessary to first determine which services to be accessed belong to one carrier, so with reference to fig. 4, as shown in fig. 5, step 401 further includes 400A and 400B:

400A, obtaining the frequency point information of all the services to be accessed of the access network equipment.

For example, the frequency point information may be obtained by the network parameter acquisition module, and the specific frequency point information example may refer to table 1, which is not described herein again.

And 400B, determining the quasi-access service with the same frequency point information as the quasi-access service belonging to the same carrier.

Note that the frequency point information is actually a number given to a fixed frequency. The frequency intervals are all 200 khz. Thus, 125 radio frequency bands are divided from 890mhz, 890.2mhz, 890.4mhz, 890.6mhz, 890.8mhz, 891mhz … … 915mhz at a frequency interval of 200khz, and each band is numbered from 1, 2, 3, 4 … … 125.

Optionally, as shown in fig. 6, because the technical solution provided in the embodiment of the present application determines resource allocation of each service based on traffic, and if the traffic required by each service is not large, and after corresponding resources are allocated completely, performance of the co-established shared base station is not affected at all, the technical solution does not need to be executed, and the corresponding resources are directly allocated according to requirements, so before step 401, the core network device 03 further needs to execute the following steps:

and S1, acquiring the average flow of each target unit time of each network loaded by the access network equipment in busy hour in a preset time period before the current unit time.

The network here includes a public network and a private network.

For example, the target unit time may be 1 hour; in order to save computing resources and ensure that the collected data can reflect traffic usage of each network carried by the access network device, the preset time period may be two consecutive weeks of tuesday (any working day) and sunday (any holiday). The busy hour can be determined by the traffic using condition of the corresponding user of the operator, for example, the busy hour can be 9:00-11:00 and 14:00-17:00 in working days, and the non-working day can be 10:00-17: 00.

Illustratively, the step S1 is mainly performed by the service distribution requirement collecting module 031 in the core network device 03 shown in fig. 2.

And S2, determining the large flow target unit time according to the average flow of each target unit time of all networks in busy hours in a preset time period.

For example, when the sum of average traffic of all networks in the target unit time in busy hour within a preset time period is greater than a third preset ratio, the target unit time is determined to be the target unit time of high traffic, where the ratio of the average traffic to the maximum traffic that can be carried by the access network device within one target unit time is greater than the third preset ratio.

And S3, judging whether the ratio of the number of the large-flow target unit time to the total target unit time corresponding to busy hours in a preset time period is larger than a second preset percentage.

When the ratio of the number of the large-flow target unit time to the total target unit time corresponding to all busy hours is larger than a second preset percentage, executing S4; when the ratio of the number of the large flow target unit times to the total target unit times corresponding to all busy hours is not greater than the second preset percentage, S1 is performed.

Illustratively, the second predetermined percentage may be 30%, or any other feasible value, and is not limited herein.

And S4, sending a corresponding instruction to the access network equipment to enable the access network equipment to acquire the reserved traffic of each network carried by the access network equipment in the current unit time.

Because the flow used by each network in the time of the large flow target unit time is more, the network can be considered to be very dependent on the flow, and if the ratio of the large flow target unit time to the total target unit time in the busy hour exceeds a certain ratio, the network carried by the access network equipment is relatively dependent on the flow, and a corresponding instruction needs to be sent to the access network equipment to enable the access network equipment to execute the technical scheme provided by the embodiment of the application.

For example, the steps S2-S4 are performed by the service dependency analysis module 032 in the core network device 03 shown in fig. 2.

It should be noted that, in practice, the core network device may not execute the step S3, and after the step S2, it is determined whether to execute the step S1 or send a corresponding command to the core network device to execute the step 401 according to the ratio of the number of the large flow target unit time to the total target unit time number corresponding to the busy hour in the preset time period. In addition, the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is equal to a second preset percentage, which can be attributed to a case that the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is greater than the second preset percentage, or can be attributed to a case that the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is less than the second preset percentage, and the case that the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is less than the second preset percentage in the example corresponding to fig. 6 is taken as an example, but the present application does not specifically limit this.

Optionally, with reference to fig. 7 in conjunction with fig. 5, when the network type is a public network or a private network, the step 401 specifically includes 4011 and 4012:

4011. and acquiring public and private network identification and data network name DNN information of at least one service to be accessed.

Specifically, the public and private network identifier and the DNN information are acquired by the network parameter acquisition module. Specifically, the contents of table 1 can be referred to.

4012. And determining the network category of each service to be accessed according to the public and private network identification and the DNN information.

Specifically, how to determine the network type of each service to be accessed according to the public-private network identifier and the DNN information may refer to the content expressed below table 1, which is not described herein again.

402. And acquiring the priority level of the service to be accessed and the service demand flow in the current unit time.

Specifically, the priority level and the traffic demand in the current unit time are obtained by the service guarantee parameter acquisition module, which can refer to table 2.

403. Calculating a priority parameter of the service to be accessed according to the priority level of the service to be accessed and the service demand flow of all the services to be accessed in a first service set to which the service to be accessed belongs; the first service set consists of proposed access services belonging to the same network class.

Because each person of the source to be accessed has practical significance only in the network where the person is located when the priority parameter is considered, the condition of other services to be accessed of the network where the person is located, namely the set of services to be accessed which are the same as the service operator and the network category of the service to be accessed, needs to be considered when the priority parameter of the service to be accessed is calculated.

Optionally, with reference to fig. 5 and fig. 8, since the service arrival time and the service requirement duration of the service to be accessed also affect the priority parameter of the service to be accessed, step 403 may include 4031 and 4032:

4031. and acquiring the service arrival time of the service to be accessed and the service requirement time of all the service to be accessed in the first service set.

Specifically, the service arrival time and the service requirement duration are obtained by the service provisioning parameter acquisition module, which can refer to table 2.

4032. And calculating the priority parameters of the service to be accessed according to the priority level and the service arrival time of the service to be accessed, and the service demand flow and the service demand duration of all the services to be accessed in the first service set to which the service to be accessed belongs.

Illustratively, when only the priority level and the traffic demand traffic are considered, step 403 calculates the priority parameter according to the following formula:

wherein Pa is_iFor the priority parameter of the ith service to be accessed, T_iThe service demand flow, T, of the ith service to be accessed in the current unit time₁To T_NTraffic demand flow for all intended access services in the first traffic set in which the ith intended access is located, PrL_iIs the priority level of the ith service to be accessed.

Illustratively, when considering the priority level, the traffic demand flow, the traffic arrival time, and the traffic demand duration, step 403 calculates the priority parameter according to the following formula:

wherein, Time_iFor the service arrival time of the ith service to be accessed, LastT_iService demand duration, LastT, for the ith service to be accessed₁To LastT_NThe service requirement duration and TTI of all the intended access services in the first service set where the ith intended access is located_preIs the time when the previous unit time starts.

404. And distributing resources for all the services to be accessed in the current unit time according to the magnitude relation of the priority parameters of at least one service to be accessed in the target carrier and the service demand flow.

Optionally, with reference to fig. 9 in combination with fig. 5, the step 404 specifically includes 4041-4043:

4041. and selecting the pre-distribution service according to a preset rule according to the magnitude relation of the priority parameter of at least one service to be accessed in the target carrier.

For example, referring to fig. 10 in conjunction with fig. 9, generally, resources are first allocated to a to-be-accessed service with a high priority, so the step 4041 may specifically be: and determining the quasi-access service with the largest priority parameter in the unallocated services except the allocated service in at least one quasi-access service corresponding to the target carrier as the pre-allocated service.

For example, taking two operators and the network type as a public network as an example, the operators, the public network, the service to be accessed and the corresponding manner of the priority parameters can be referred to as the following table 5.

TABLE 5

For example, taking two operators and the network type as a public network as an example, the corresponding manner of the operators, the private network, the service to be accessed and the priority parameter can be referred to table 6 below.

TABLE 6

Before the step 4041 is executed, for the carrier of the operator a, the intended access services belonging to the same operator in tables 5 and 6 need to be arranged in the order of priority parameter from large to small or from small to large, so as to conveniently execute the step 4041, and the operator B performs the same operation.

4042. And when determining that the corresponding resources are allocated to the pre-allocated service, increasing the total flow in the target carrier in the current unit time, and when the sum of the service demand flows of all allocated services and the services to be allocated in a second service set to which the services to be allocated belong is less than a preset threshold value, allocating the corresponding resources to the pre-allocated service in the current unit time.

The distributed service is a proposed access service distributed with corresponding resources; the preset threshold value formed by the intended access services belonging to the same network category of the same operator in the second service set may be a preset flow rate of a network (for example, a private network j of the operator a) to which the second service set belongs in a unit time, and may be specifically obtained by the aforementioned differentiated carrier capacity customization module.

For example, the corresponding resource may be an RB (resource block, resource element) or an RE (resource element). The resources may be specifically allocated to the service to be accessed according to the current communication protocol standard. Allocating corresponding resources for the service, which may be understood herein as accessing the user terminal corresponding to the service to the access network device according to 5 QI.

Specifically, in the practical case of allocating resources (e.g. RBs) for a service, if there are more services to be allocated (there are more corresponding user terminals), some resources need to be used for distinguishing resources of different services, so that some resources cannot be effectively utilized, and thus, traffic that can be provided by a carrier where the service is located in a unit time is reduced, and this situation may cause waste of resources and is therefore not allowed.

Optionally, with reference to fig. 11 in conjunction with fig. 10, the method further includes 4042A:

4042A, when it is determined that the pre-allocated service is allocated with the corresponding resource, the total traffic of the target carrier in the current unit time is reduced, or the sum of the traffic demand flows of all allocated services in the second service set to which the service to be allocated belongs is greater than a preset threshold, the resource allocated for the pre-allocated service in the current unit time is empty.

It should be noted that, the fact that the resource allocated to a certain service is empty may be understood as rejecting the access of the user terminal corresponding to the service. In addition, in this embodiment of the present application, "the total traffic in the target carrier at the current unit time is not changed" may be attributed to a case of "the total traffic in the target carrier at the current unit time is decreased", or may be attributed to a case of "the total traffic in the target carrier at the current unit time is increased", which is not specifically limited in this application; the "sum of the service demand flows of all allocated services in the second service set to which the service to be allocated belongs is equal to the preset unit flow of the network in which the second service set is located" may be attributed to a case that "the sum of the service demand flows of all allocated services in the second service set to which the service to be allocated belongs is greater than the preset unit flow of the network in which the second service set is located", or may be attributed to a case that "the sum of the service demand flows of all allocated services in the second service set to which the service to be allocated belongs is less than the preset unit flow of the network in which the second service set is located", which is not specifically limited by the present application.

4043. And determining the pre-allocated service as the allocated service.
