Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a user access method and an access network device.
Background
With the continuous evolution of networks, diversified industrial application requirements 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 to meet the access complaints of 2B (which can be understood as private network) users and 2C (which can be understood as public network) users of different operators as much as possible under the condition that resources of the shared base station after co-construction are limited becomes a problem to be solved urgently.
Disclosure of Invention
The invention provides a user access method and access network equipment, which can meet the access requirements of user terminals corresponding to different services borne by a shared base station based on flow, total RRC connection number and data transmission RRC connection number.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides a user access method, which is applied to an access network device, where the access network device provides support for public network services and private network services of each operator in multiple operators through a single carrier. The user access method comprises the following steps: the method comprises the steps that the access network equipment acquires network data of each service in the public network service and the private network service of each operator in current unit time, wherein the network data comprise reserved flow, reserved Radio Resource Control (RRC) connection number and data transmission RRC connection number; determining a composite parameter corresponding to each service according to the network data of each service; when determining that a first service exists in all public network services and private network services and a composite parameter corresponding to the first service is larger than the product of a preset parameter corresponding to the first service and a preset percentage, determining that the service priority is smaller than or equal to the sum of composite parameters corresponding to a second service of the first service; and when the sum of the composite parameters corresponding to the second service is smaller than the preset threshold value, allowing the new user terminal corresponding to the first service to access in the current unit time.
According to the user access method provided by the invention, after the access network equipment acquires the network data of each service in all public network services and private network services in the current unit time, wherein the network data comprises the reserved flow, the reserved RRC connection number and the RRC connection number with data transmission, the composite parameter corresponding to each service is determined according to the network data of each service. And then judging whether the composite parameter corresponding to the first service is larger than the product of the preset parameter corresponding to the first service and the preset percentage. If the composite parameter corresponding to the first service is about to exceed the preset parameter corresponding to the first service, it needs to determine whether a new user terminal corresponding to the first service is allowed to access the access network device in time. Because the priorities of the public network service and the private network service are different, it is necessary to ensure that the user terminal corresponding to the service with the higher priority is accessed, after the first service is determined to exist, it can be determined that the service priority is less than or equal to the sum of the composite parameters corresponding to the second service of the first service, and it is determined whether the sum of the composite parameters corresponding to the second service is less than a preset threshold. If the sum of the composite parameters corresponding to the second service is determined to be smaller than the preset threshold, it indicates that the composite parameters corresponding to the second service do not exceed the agreed composite parameters, and the unused bandwidth of the second service can be allocated to the new user terminal of the first service, so that the access network device can allow the new user terminal corresponding to the first service to access in the current unit time. Therefore, the access requirements of the user terminals corresponding to different services borne by the shared base station are met based on the flow, the total RRC connection number and the data transmission RRC connection number.

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.
In the related art, 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, currently, a shared base station is established by multiple operators to carry service requirements of the multiple operators. However, how to satisfy the access requirements of users corresponding to private network services and users corresponding to public network services of different operators for the co-established shared base station is a problem to be solved urgently.
In order to solve the above problem, embodiments of the present invention provide a user access method, which can satisfy access requirements of user terminals corresponding to different services carried by a shared base station based on a traffic, a total RRC connection number, and a number of RRC connections with data transmission.
The user access method provided by the embodiment of the invention can be applied to the system architecture shown in fig. 1. As shown in fig. 1, the system architecture may include: a terminal 01, an access network device 02 and at least one core network device 03. Each core network device 03 corresponds to an operator core network, and the operator core network is a private network core network or a public network core network. Wherein, the private network core network supports 2B service or private network service, and the public network core network supports 2C service or public network service.
It should be noted that, in the embodiment of the present invention, one operator core network corresponds to one public network and multiple private networks. Public network services (also called 2C services) refer to all services in a public network, and private network services (also called 2B services) refer to all services in a private network.
Illustratively, referring to fig. 1, the core network device 03 includes four core network devices 03-1, 03-2, 03-3, and 03-4, which are described as examples. The 03-1 may correspond to a core network of a public network of the operator 1, the 03-2 may correspond to a core network of a private network of the operator 1, the 03-3 may correspond to a core network of a public network of the operator 2, and the 03-4 may correspond to a core network of a private network of the operator 2. In this way, after the terminal 01 and the access network device 02 are connected, 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.
In some embodiments, the access network device 02 may be an access network device (BTS) in a global system for mobile communication (GSM), a Code Division Multiple Access (CDMA), an access network device (Node B, NB) in a Wideband Code Division Multiple Access (WCDMA), an access network device (evolved Node B, eNB) in a Long Term Evolution (Long Term Evolution, LTE), an access network device (eNB) in an internet of things (IoT) or a narrowband internet of things (NB-B ), an access network device in a future 5G mobile communication network or a future evolved Public Land Mobile Network (PLMN), which is not limited in any way by the embodiments of the present invention.
In some embodiments, terminal 01 is known by a different name, such as User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a vehicular user equipment, a terminal agent or terminal device, and so forth. The terminal may be a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) Virtual Reality (VR) device, and other devices that can communicate with a base station.
Referring to fig. 2 in conjunction with fig. 1, functional modules in the core network device 03 may include: a service distribution requirement collection module 031, a service dependency analysis module 032, and a composite parameter customization module 033.
The service distribution requirement collecting module 031 may collect network data of a private network service or a public network service of an operator corresponding to the access network device 02 (e.g., a base station) connected thereto. The network data may include: traffic related data (average capacity/traffic per hour, maximum capacity/traffic per hour) of the traffic corresponding to the network, maximum number of RRC connections per hour, average number of RRC connections with data transfer per hour, maximum number of RRC connections with data transfer per hour, and the like.
The service dependency analysis module 032 may determine, through matching with the service dependency analysis module 032 in another core network device corresponding to the access network device 02 connected thereto, the service dependency degree of the service in the actual scene corresponding to the network data on the traffic and the user connection number by using the network data acquired by the service distribution requirement collection module 031 corresponding to the service dependency analysis module 032 through a certain calculation, thereby obtaining a service dependency ratio between the traffic and the user connection number, so as to be used for subsequent composite parameter calculation. Of course, if all the core networks correspond to the same core network device, the service dependency analysis module 032 included therein independently completes the above calculation process.
In a specific implementation, the process of determining the service dependency ratio between the traffic and the number of user connections by the service dependency analysis module 032 is as follows:
1. and acquiring the average flow and the average RRC connection number of each service in each hour during busy hours in a preset time period.
For example, the preset time period may be two weeks (any working day) and two weeks (any resting day) in succession. Busy hours may be determined by the operator as a practical matter, for example, on weekdays 9:00-11:00 and 14:00-17:00, and on non-weekdays 10:00-17: 00.
2. And determining the second unit time of the large flow and the second unit time of the RRC according to the average flow and the average RRC connection number of all the services in busy hours in a preset time period.
When the sum of average traffic of all the services in a first target hour of busy hours in a preset time period is greater than a preset ratio (for example, 30%) of the access network device capable of carrying the maximum traffic in one hour, determining that the first target hour is a second unit time of the large traffic.
When the sum of the average RRC connection number in the second target hour of all the services in busy hours in a preset time period is larger than a preset ratio (for example, 30%) of the ratio of the average RRC connection number in the second target hour to the maximum RRC connection number which can be carried by the access network equipment in one hour, the second target hour is determined to be RRC second unit time. Or, when the ratio of the sum of the average number of data-transferred RRC connections in the second target hour of busy hours of all the services in the preset time period to the maximum number of data-transferred RRC connections that the access network device can carry in one hour is greater than the preset ratio (for example, 30%), determining that the second target hour is the second unit time of RRC.
3. And judging whether the ratio of the number of the first target hours to the total number of busy hours in a preset time period is greater than a preset percentage, or judging whether the ratio of the number of the second target hours to the total number of busy hours in the preset time period is greater than the preset percentage.
When the ratio of the total number of hours when the first target hour is busy in a preset time period is less than or equal to a preset percentage (for example, 30%), or the ratio of the total number of hours when the second target hour is busy in the preset time period is less than or equal to the preset percentage, it is determined that the user access method of the embodiment of the present invention is executed by using an algorithm based on a composite parameter.
4. And determining the influence coefficient of the flow in the composite parameter and the influence coefficient of the RRC connection number in the composite parameter.
The following formula can be used to determine the influence coefficient of the flow rate in the composite parameter:
wherein Z isTAs a factor of influence of the flow in the composite parameter, HFlow rate Is effectiveIs the ratio of the number of the first target hours to the total number of the hours of busy hour in the preset time period, HRRC Is effectiveIs the ratio of the total number of hours when the number of second target hours is busy within a preset time period.
The following formula can be adopted to determine the influence coefficient of the RRC connection number in the composite parameter:
and the composite parameter customizing module 033 is configured to calculate, through cooperation of the composite parameter customizing modules 033 in other core network devices corresponding to the access network device 02 connected thereto, preset parameters recommended for the public network service and the private network service of different operators according to network data acquired by the service distribution demand collecting module 031 corresponding to each composite parameter customizing module. Of course, if all the core networks correspond to the same core network device, the composite parameter customization module 033 included therein independently completes the above calculation process.
Illustratively, assuming a unit time of 1 second, then:
1. the preset flow of the public network service can be calculated by the following formula:

401. and acquiring network data of each service in the current unit time in the public network service and the private network service of each operator.
The network data may include reserved traffic, the number of reserved RRC connections, and the number of data-carrying RRC connections. It is to be understood that the reserved RRC connection number refers to the maximum number of RRC connections in the current unit time, and the number of RRC connections that are in data transfer refers to the number of RRC connections that are in data transfer in the reserved RRC connection number.
Optionally, in the embodiment of the present invention, in order to ensure that the access request of the ue is processed in time based on the traffic, the total RRC connection number, and the number of RRC connections with data transmission, the unit time here may be one second. Of course, the unit time may be smaller as the technology actually allows, and is not particularly limited herein.
For example, step 401 may be executed by the traffic and connection number real-time monitoring module 021, where the network data obtained by the module in real time is shown in table 1.
TABLE 1
Wherein YY represents the year, MM represents the month, DD represents the day of the MM month, HH: SS stands for time minute second.
402. And determining a composite parameter corresponding to each service according to the network data of each service.
Optionally, in this embodiment of the present invention, this step 402 may be performed by the above-mentioned composite parameter calculation module 022. After the real-time traffic and connection number monitoring module acquires the network data of each service in the current unit time in real time, the real-time traffic and connection number monitoring module can send the network data to the composite parameter calculating module. The composite parameter calculation module may calculate a composite parameter corresponding to each service according to the network data of each service.
Specifically, the following formula is adopted by the composite parameter calculation module to calculate the composite parameter corresponding to the public network service:
wherein, Ki PUA composite parameter, T, corresponding to the public network service of operator ii PUFor the reserved flow of the public network service of the operator i in the current unit time, RRCi PUThe number of reserved RRC connections, RSC, of the public network service of the operator i in the current unit timei PUThe number of RRC connections which are transmitted in the current unit time for the public network service of the operator i.
The composite parameter calculating module may adopt the following formula for calculating the composite parameter corresponding to the private network service:
wherein, Kij PrIs a composite parameter, T, corresponding to the private network service j of the operator iij PrReserved flow of private network service j of operator i in current unit time, RRCij PrThe number of reserved RRC connections, RSC, of the private network service j of the operator i in the current unit timeij PrAnd the number of the RRC connections with data transmission of the private network service j of the operator i in the current unit time.
403. And when determining that the first service exists in all the public network services and the private network services and the composite parameter corresponding to the first service is greater than the product of the preset parameter corresponding to the first service and the preset percentage, determining that the service priority is less than or equal to the sum of the composite parameters corresponding to the second service of the first service.
The preset parameter corresponding to the first service is data calculated by the composite parameter customization module in the embodiment.
After determining the composite parameter corresponding to each service, the composite parameter calculation module may send the determined composite parameter to the composite parameter determination module. The composite parameter judging module can judge whether a first service exists in all public network services and private network services, wherein the composite parameter corresponding to the first service is larger than the product of a preset parameter corresponding to the first service and a preset percentage. And if the first service does not exist, the access network equipment allows the user terminals corresponding to all the services to normally access the access network equipment in the current unit time. If the first service exists, the network load balancing module judges whether to start the load balancing in the carrier. Specifically, the network load balancing module may determine that the service priority is less than or equal to the sum of the composite parameters corresponding to the second service of the first service.
It can be understood that the above normal access network device refers to a situation that the current 5QI (5G QoS Identifier) is maintained, and a new user terminal corresponding to each service is allowed to access the access network device. The 5QI is used to identify the Qos (Quality of Service) of 5G. In addition, since the base station needs to be set aside a part of the emergency bearer capacity, the first preset percentage may be 95% (for example only, and may be any other feasible value in practice).
Optionally, in the embodiment of the present invention, when the first service is a public network service, the second service is a public network service other than the first service in public network services of all operators. When the first service is a private network service, the second service is other services except the first service in public network services and private network services of all operators.
For example, when the first service is a public network service, the network load balancing module may determine that the sum of the composite parameters corresponding to the second service is the following formula:
wherein, KPU nowIs the sum of composite parameters, K, corresponding to the second servicek PUA composite parameter corresponding to the kth public network service in all public network services (N in total) loaded by the access network equipment, Ky PUAnd the composite parameter is corresponding to the first service. N is a positive integer, and k is a positive integer.
When the first service is a private network service, the network load balancing module determines that the sum of the composite parameters corresponding to the second service can adopt the following formula:
wherein, KA nowIs the sum of composite parameters, K, corresponding to the second servicek PUA composite parameter corresponding to the kth public network service in all public network services (N in total) loaded by the access network equipment, Km PrA composite parameter, K, corresponding to the mth private network service in all the private network services (M in total) carried by the access network equipmenty PrAnd the composite parameter is corresponding to the first service. N, k, M and M are positive integers.
404. And when the sum of the composite parameters corresponding to the second service is smaller than the preset threshold value, allowing the new user terminal corresponding to the first service to access in the current unit time.
After determining the sum of the composite parameters corresponding to the second service, the network load balancing module may determine whether the sum of the composite parameters corresponding to the second service is smaller than a preset threshold. And if the sum of the composite parameters corresponding to the second service is less than the preset threshold, allowing the new user terminal corresponding to the first service to access in the current unit time.
It can be understood that, when the first service is a private network service, since the service priority of the private network service is higher than that of the public network service, the service usage of the private network user needs to be preferentially guaranteed, so as long as the access network device itself can bear the load, the usage of the private network service needs to be satisfied, that is, a new user terminal corresponding to the private network service is allowed to access.
When the first service is a public network service, the public network service is considered only on the basis of ensuring the use of the private network service because the service priority of the public network service is lower, so that for the over-standard public network service, only when the sum of the composite parameters corresponding to other public network services is smaller than the sum of the corresponding preset parameters, the new user terminal corresponding to the public network service can be allowed to access.
Optionally, in the embodiment of the present invention, when the first service is a public network service, the preset threshold is a sum of preset parameters corresponding to the second service. When the first service is a private network service, the preset threshold is a difference value between the maximum composite parameter which can be carried by the access network equipment and the composite parameter corresponding to the first service.
Optionally, in the embodiment of the present invention, the allowing may be that the access network device allows the service request of the user terminal and establishes a response connection and issues a response configuration; but any other feasible way.
It should be noted that, in the embodiment of the present invention, there is also a case that the user terminal corresponding to the public network service or the private network service in the previous unit time does not access the network any more in the current unit time, in this case, the new user terminal may refer to an optional part of the user terminals in the current unit time as the new user terminal, and the number of the user terminals remaining after the selection is the same as the number of the user terminals in the previous unit time. Of course, there may be any other possible situations (for example, if the priorities of the user terminals belonging to the same service (public network service or private network service) are different, a new user terminal needs to be selected from a part of user terminals with a lower priority according to the priority), and the new user terminal is specifically selected according to the specific situation.
According to the user access method provided by the invention, after the access network equipment acquires the network data of each service in all public network services and private network services in the current unit time, wherein the network data comprises the reserved flow, the reserved RRC connection number and the data-transmitted RRC connection number, the composite parameter corresponding to each service is determined according to the network data of each service. And then judging whether the composite parameter corresponding to the first service is larger than the product of the preset parameter corresponding to the first service and the preset percentage. If the composite parameter corresponding to the first service is about to exceed the preset parameter corresponding to the first service, it needs to determine whether a new user terminal corresponding to the first service is allowed to access the access network device in time. Because the priorities of the public network service and the private network service are different, it is necessary to ensure that the user terminal corresponding to the service with the higher priority is accessed, after the first service is determined to exist, it can be determined that the service priority is less than or equal to the sum of the composite parameters corresponding to the second service of the first service, and it is determined whether the sum of the composite parameters corresponding to the second service is less than a preset threshold. If the sum of the composite parameters corresponding to the second service is determined to be smaller than the preset threshold, it indicates that the composite parameters corresponding to the second service do not exceed the agreed composite parameters, and the unused bandwidth of the second service can be allocated to the new user terminal of the first service, so that the access network device can allow the new user terminal corresponding to the first service to access in the current unit time. Therefore, the access requirements of the user terminals corresponding to different services borne by the shared base station are met based on the flow, the total RRC connection number and the data transmission RRC connection number.
Optionally, in this embodiment of the present invention, with reference to fig. 4, as shown in fig. 5, the user access method provided in this embodiment of the present invention may further include step 405.
405. And when the sum of the composite parameters corresponding to the second service is determined to be larger than a preset threshold value, forbidding the access of a new user terminal corresponding to the first service in the current unit time.
It can be understood that the prohibition here may be that the access network device rejects the service request of the user terminal; but any other feasible way.
