Description

User access method and access network equipment

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

Fifth generation mobile communication technology (5 th-generation, 5G) networks provide multiple slicing modes that can meet both consumer (customer to customer, 2C) and enterprise (business to business, 2B) needs.

The transceiving devices (e.g. access network devices) in a 5G network are typically multi-antenna devices, such as: 64 transceiving (transmitter and receiver, TR) devices, resulting in extremely high networking costs. Therefore, operators begin to seek a scheme of co-building base stations by multiple operators and performing network deployment by using the co-built base stations. Co-building a base station means that one base station can meet the needs of multiple operators, and does not concentrate the equipment of multiple operators in the same base station.

How to meet the access requirements of 2B (which can be understood as private network) users and 2C (which can be understood as public network) users of different operators as far as possible under the condition of limited resources of the co-established shared base station becomes a problem to be solved urgently.

Disclosure of Invention

The invention provides a user access method and access network equipment, which solve the problem that how to meet 2B (can be understood as private network) users and 2C (can be understood as public network) users of different operators as much as possible under the condition of limited resources of a shared base station after co-establishment becomes urgent to be solved.

In order to achieve the above purpose, the invention adopts the following technical scheme:

in a first aspect, an embodiment of the present invention provides a user access method, applied to an access network device, where the access network device provides support for public network service and private network service of an operator through a carrier wave, including: and acquiring network data of the target service of each of N operators in the current unit time. The target services comprise K private network services, the network data at least comprise RRC connection numbers and data transmission connection numbers, N is an integer greater than or equal to 2, and K is an integer greater than or equal to 1. And determining the bandwidth demand of the kth private network service in the current unit time according to the network data of the N operators when the RRC connection number of the kth private network service of the nth operator is determined to be larger than a first threshold value and/or the data transmission connection number of the kth private network service is determined to be larger than a second threshold value. Wherein n is an integer, k is an integer, and n is an integer. And when the residual bandwidth of the nth operator is determined to be larger than the bandwidth demand, allowing a new user of the kth private network service to access core network equipment corresponding to the kth private network service in the current unit time.

It can be seen that, according to the network data of the current unit time, the access network device can determine whether the RRC connection number of the kth private network service of the nth operator is greater than the first threshold value, and/or whether the data transmission connection number of the kth private network service is greater than the kth private network service of the second threshold value, so as to determine whether a new user of the kth private network service can access the core network device corresponding to the kth private network service in the current unit time. When the number of RRC connections of the kth private network service of the nth operator is determined to be greater than the first threshold value and/or the number of data transmission connections of the kth private network service is determined to be greater than the second threshold value, the method indicates that the kth private network service requests more new users to be accessed in the current unit time at the moment, so that the bandwidth demand of the kth private network service in the current unit time needs to be determined. And when the residual bandwidth of the nth operator is determined to be larger than the bandwidth demand, allowing a new user of the kth private network service to access core network equipment corresponding to the kth private network service in the current unit time. Therefore, the problem of how to meet the access requirements of 2B (which can be understood as private network) users and 2C (which can be understood as public network) users of different operators as far as possible under the condition that resources of the commonly-built shared base station are limited is solved.

And the processing unit is used for determining the bandwidth demand of the kth private network service in the current unit time according to the network data of the N operators acquired by the acquisition unit when the RRC connection number of the kth private network service of the nth operator acquired by the acquisition unit is larger than a first threshold value and/or the data transmission connection number of the kth private network service acquired by the acquisition unit is larger than a second threshold value. Wherein n is an integer, k is an integer, and n is an integer. And the processing unit is further configured to allow the new user of the kth private network service to access the core network device corresponding to the kth private network service in the current unit time when the remaining bandwidth of the nth operator is determined to be greater than the bandwidth demand.

Detailed Description

Embodiments of the present invention are described below with reference to the accompanying drawings.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In order to clearly describe the technical solution of the embodiments of the present invention, in the embodiments of the present invention, the terms "first", "second", etc. are used to distinguish the same item or similar items having substantially the same function and effect, and those skilled in the art will understand that the terms "first", "second", etc. do not limit the number and execution order.

In view of the above problems, an embodiment of the present invention provides a user access method, which can satisfy access requirements of user terminals corresponding to different services carried by a shared base station (access network device) co-established by different operators based on a radio resource control (radio resource control, RRC) connection number and a data transmission connection number (which indicates the RRC connection number with data transmission). The method is applied to the system architecture shown in fig. 1, and the system can comprise: 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), each core network device 03 corresponding to one operator core network (private network core network (supporting 2B services) or public network core network (supporting 2C services)). Illustratively, referring to FIG. 1, 03-1 may correspond to a public network core network of operator A, 03-2 may correspond to a private network core network of operator A, 03-3 may correspond to a public network core network of operator B, and 03-4 may correspond to a private network core network of operator B. After the terminal 01 access network device 02 is connected with the access network device, the terminal can access the public network core network or the private network core 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 plurality of core network devices may be completed.

In the present invention, public network service (2C service) refers to all services in the public network, and private network service (2B service) refers to all services in the private network.

As an example, referring to fig. 2, the functional modules in the core network device 03 may include a service distribution requirement collection module 031, a service dependency analysis module 032, a critical user parameter customization module 033, and an operator carrier bandwidth customization module 034. The service distribution requirement collection module 031 may collect network data of a private network service or a public network service of a corresponding operator of the access network device 02 (e.g., a base station) to which the service distribution requirement collection module is connected. The network data may include: the related data (average RRC connection number per unit time (e.g., hour)/average RRC connection number with data transmission, maximum RRC connection number per unit time (e.g., hour)/maximum RRC connection number with data transmission) of the service corresponding to the network, traffic of the service, or the number of users, etc.

The service dependency analysis module 032 may determine, through a certain calculation, whether the service in the actual scenario corresponding to the network data is mainly dependent on the RRC connection number and the RRC connection number with data transmission 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 other core network devices 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 in the core network device independently completes the calculation process.

The key user number parameter customizing module 033 is configured to calculate, through cooperation of the key user number parameter customizing module 033 in other core network devices corresponding to the access network device 02 connected thereto, a contracted RRC connection number (first threshold) and a contracted data transmission RRC connection number (second threshold) per target unit time recommended for public network services and private network services of different operators according to the network data acquired by the service distribution demand collecting module 031 corresponding to each key user number parameter customizing module. Of course, if all the core networks correspond to the same core network device, the key capacity customization module included in the core network device independently completes the calculation process.

Illustratively, taking 1 second per unit time and 1 hour per unit time as an example, the first threshold and the second threshold of the private network service may be calculated by the following formula:

wherein ,

representing contracted private network user access number per second,/->

Representing the agreed subscriber access number of private network-specific data transfer per second +.>

Indicating the maximum RRC connection number per hour of private network,/->

Represents the average RRC connection number per hour of private network,/->

RRC connection number indicating maximum data transmission per hour of private network,/H>

The RRC connection number indicating the average number of data transmissions per hour for the private network.

And the carrier bandwidth customizing module 034 is configured to obtain the RRC connection numbers of different carriers and the RRC connection numbers with data transmission in the area where the base station is to be deployed, and determine the initial bandwidth of each carrier.

Wherein the initial bandwidth satisfies

Wherein i represents carrier i, j is the j-th private network under carrier i, W is the total bandwidth supported by the base station, and floor represents the downward rounding of the calculated value.

For example, referring to fig. 2, the access network device 02 includes a user real-time monitoring module 021, a user discriminating module 022, and a network load balancing module 023. The user number real-time monitoring module 021 can collect the RRC connection number and the RRC connection number with data transmission of private network service and public network service of each operator according to the time granularity of unit time (1 second). The user number discriminating module 022 may determine whether the subsequent network load balancing module 023 is required to reject or allow the access request of the user terminal of each service according to the RRC connection number and the RRC connection number with data transmission collected by the service distribution demand collecting module 031.

By way of example, and taking a 5G communication network as an example, referring to fig. 3, the actual means in the access network device 02 may comprise a radio frequency unit and a baseband processing unit. The radio frequency unit is connected with the baseband processing unit through a common public radio interface (common public radio interface, CPRI (eCRPI)), and the public network core network (5 GC 1) of the operator a, the public network core network (5 GC 2) of the operator B, the private network core network (5 GC 3) of the operator a, and the private network core network (5 GC 4) of the operator B are all connected with the baseband processing unit of the access network device 2 through NG interfaces.

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

The 5G radio frequency unit comprises an antenna unit, a switch, a first combiner, a second combiner, a first transceiver and a second transceiver. Each transceiver includes, among other things, digital up-conversion (digital up conversion, DUC), digital-to-analog converter (digital to analog converter, DAC), transmit antenna (TX), receive antenna (RX), analog-to-digital converter (analog to digital converter, ADC), and digital down-conversion (digital down conversion, DDC).

Specifically, in the technical solution provided in the present invention, the access network device 02 allocates a carrier to each operator to carry the public network service and the private network service of the operator. Each carrier comprises an uplink carrier and a downlink carrier, the communication link corresponding to the uplink carrier is composed of an antenna unit, a switch, RX, ADC, DDC and a 5G baseband processing unit in fig. 3, and the communication link corresponding to the downlink carrier is composed of an antenna unit, a switch, TX, DAC, DUC and a 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 in the access network device, the user terminal of the operator a may transmit through a first carrier when initiating a private network service or a public network service, and the user terminal of the operator B may transmit through a second carrier when initiating a private network service or a public network service. The first carrier comprises a first transceiver, a first combiner, a switch and an antenna unit; the second carrier includes a second transceiver, a second combiner, a switch, and an antenna unit.

In an embodiment of the present invention, the access network device 02 may be an access network device (basetransceiver station, BTS) in a global system for mobile communications (globalsystem formobilecommunication, GSM), a code division multiple access (code division multiple access, CDMA), an access network device (node B, NB) in a wideband code division multiple access (wideband code division multiple access, WCDMA), an access network device (evolvedNode B, eNB) in a long term evolution (Long Term Evolution, LTE), an eNB in an internet of things (internet of things, ioT) or a narrowband internet of things (NB-IoT), an access network device in a future 5G mobile communication network or a future evolved public land mobile network (public land mobile network, PLMN), which is not limited in any way by the embodiments of the present invention.

By way of example, the terminal 01 in the embodiments of the present invention may be named differently, such as a 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 vehicle user equipment, a terminal agent, or a terminal apparatus, etc. It may specifically be a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, a cellular phone, a personal digital assistant (personal digital assistant, PDA), an augmented reality (augmented reality, AR) \virtual reality (VR) device, and the like, which may communicate with the base station, and the specific form of the terminal is not limited in the embodiments of the present invention.

The user access method provided by the embodiment of the present invention is described below with reference to the communication system shown in fig. 1, taking the access network device 02 as an example of a base station.

As shown in fig. 4, the user access method provided by the embodiment of the present invention is applied to a base station, where the base station provides support for public network service and private network service of an operator through a carrier wave, and includes:

S11, the base station acquires network data of the target service of each operator in N operators in the current unit time. The target services comprise K private network services, the network data at least comprise RRC connection numbers and data transmission connection numbers, N is an integer greater than or equal to 2, and K is an integer greater than or equal to 1.

Illustratively, in order to ensure timely processing of the access request of the user terminal based on the RRC connection number and the data transfer connection number (also referred to as the RRC connection number with data transfer), the unit time may be one second. Of course, the unit time may be smaller as the technology allows in practice, and there is no specific limitation here.

For example, in practice S11 may be executed by the foregoing flow real-time monitoring module, and the record after the data is collected is as follows in table 1:

TABLE 1

Wherein YY represents year, MM represents month, DD represents day of MM month, HH: SS stands for time minutes and seconds.

Optionally, referring to fig. 5, because the technical solution provided in the embodiment of the present invention determines whether the ue of each service is accessible based on the RRC connection number and the RRC connection number with data transmission, if the RRC connection number required by each service and the RRC connection number with data transmission are not large, and do not affect the performance of the co-established shared base station, the technical solution does not need to be executed, so before step S11, the core network device 03 further needs to execute the following steps:

S1, core network equipment 03 obtains the average RRC connection number and average RRC connection number with data transmission of each target unit time in busy time in a preset time period before the current unit time of each service borne by a base station.

Illustratively, the target unit time may be 1 hour; in order to save the computing resources and ensure that the collected data can reflect the RRC connection number of each service carried by the base station and the RRC connection number usage condition with data transmission, the preset time period may be two consecutive weeks (all days of work) and weekdays (all days of rest). The busy hour can be determined by the operator according to the traffic use condition of the corresponding user, for example, the busy hour can be 9:00-11:00 and 14:00-17:00 on the working day, and the busy hour can be 10:00-17:00 on the non-working day.

Illustratively, the step S1 is mainly performed by the service dependency analysis module 032 in the core network device 03 shown in fig. 2.

S2, the core network device 03 determines a large-flow target unit time according to the average RRC connection number and the average RRC connection number with data transmission of each target unit time of all the services in the busy hour in a preset time period.

For example, when the sum of the average RRC connection numbers of all the services in the target unit time in busy hours in the preset period is greater than the third preset duty ratio, the target unit time is determined to be a large-traffic target unit time.

And when the sum of the average number of RRC connection with data transmission in the target unit time in busy hours in the preset time period of all the services is larger than the fourth preset duty ratio in the target unit time, determining that the target unit time is the large-flow target unit time.

And S3, the core network device 03 judges whether the number of the large-flow target unit time is larger than a preset percentage or not according to the ratio of the number of the large-flow target unit time to the total target unit time corresponding to busy hours in the preset time period.

S4, executing when the number of the large-flow target unit time is larger than a preset percentage and 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 preset percentage; and when the number of the large-flow target unit time is not larger than the preset percentage, executing S1.

The preset percentage may be 30% or any other feasible number, and is not particularly limited herein.

And S4, the core network equipment 03 sends a corresponding instruction to the base station so as to acquire the RRC connection number and the transmitted RRC connection number of each service carried by the base station in the current unit time.

Because the traffic used by each service in the time of the large traffic target unit time is more, the large traffic target unit time can be considered to be very dependent on the number of RRC connections and the number of RRC connections with transmission, and if the ratio of the total target unit time in the busy time exceeds a certain ratio, the traffic carried by the base station is indicated to be relatively dependent on the number of RRC connections and the number of RRC connections with transmission, and a corresponding instruction needs to be sent to the base station to enable the base station to execute the technical scheme provided by the embodiment of the invention.

Illustratively, the steps S2-S4 described above 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, directly determine whether to execute the step S1 or send a corresponding instruction to the core network device according to the ratio of the number of large-flow target unit times to the total number of target unit times corresponding to the busy time in the preset time period, so that the step S12 may be executed. In addition, the ratio of the number of the large-flow target unit times to the total target unit times corresponding to all busy hours is equal to the preset percentage, which may be attributed to the case where the ratio of the number of the large-flow target unit times to the total target unit times corresponding to all busy hours is greater than the preset percentage, or the case where the ratio of the number of the large-flow target unit times to the total target unit times corresponding to all busy hours is less than the preset percentage, and the example corresponding to fig. 5 takes the case where the ratio of the number of the large-flow target unit times to the total target unit times corresponding to all busy hours is less than the preset percentage as an example, but the invention is not limited thereto.

And S12, the base station determines the bandwidth demand of the kth private network service in the current unit time according to the network data of the N operators when the RRC connection number of the kth private network service of the nth operator is greater than a first threshold value and/or the data transmission connection number of the kth private network service is greater than a second threshold value. Wherein n is an integer, k is an integer, and n is an integer.

Alternatively, the first threshold may be

The second threshold is->

Therefore, the problem that the base station cannot allow a new user to access when the number of RRC connections corresponding to the accessed user is excessive can be prevented.

And S13, when the base station determines that the residual bandwidth of the nth operator is larger than the bandwidth demand, allowing a new user of the kth private network service to access core network equipment corresponding to the kth private network service in the current unit time.

From the above, the base station may determine, according to the network data of the current unit time, whether the RRC connection number of the kth private network service of the nth operator is greater than the first threshold, and/or whether the data transmission connection number of the kth private network service is greater than the kth private network service of the second threshold, so as to determine whether a new user of the kth private network service in the current unit time can access the core network device corresponding to the kth private network service. When the base station determines that the RRC connection number of the kth private network service of the nth operator is greater than the first threshold value and/or the number of data transmission connections of the kth private network service is greater than the second threshold value, it is indicated that the kth private network service requests more new users to be accessed in the current unit time at this time, so that it is required to determine the bandwidth demand of the kth private network service in the current unit time. And when the base station determines that the residual bandwidth of the nth operator is greater than the bandwidth demand, allowing a new user of the kth private network service to access core network equipment corresponding to the kth private network service in the current unit time.

In one implementation manner, when the target service further includes the public network service, in this case, as shown in fig. 6 in conjunction with fig. 4, the user access method provided in the embodiment of the present invention further includes S14.

S14, the base station determines that the RRC connection number of the public network service of the nth operator is larger than a third threshold value, and/or the data transmission connection number of the public network service of the nth operator is larger than a fourth threshold value, and forbids a new user of the public network service of the nth operator from accessing core network equipment corresponding to the public network service of the nth operator in the current unit time.

For example, taking 1 second per unit time and 1 hour per unit time as an example, the third threshold and the fourth threshold of the public network service may be calculated by the following formulas:

wherein ,

represents the contracted public network user access number per second, < >>

Representing agreed user access number with data transmission per second of public network, < >>

Indicating the maximum RRC connection number per hour of the public network,/->

Showing average RRC connection number per hour for public network,/->

RRC connection number indicating maximum data transmission per hour of public network,/for the public network>

The public network has average number of RRC connections per hour.

The third threshold value may be

The fourth threshold is +.>

In one implementation manner, when it is determined that the RRC connection number of the kth private network service of the nth operator is less than or equal to the first threshold and the number of data transmission connections of the kth private network service of the nth operator is less than or equal to the second threshold and it is determined that the RRC connection number of the public network service of the nth operator is less than or equal to the third threshold and the number of data transmission connections of the public network service of the nth operator is less than or equal to the fourth threshold, the base station normally accesses the public network service of the nth operator and the new user of the K private network service. The normal access refers to a case of maintaining the current 5QI (5G QoS Identifier) (QoS (Quality of Service, quality of service) for identifying 5G) unchanged, and allowing a new user terminal corresponding to each service to access.

In practical application, the priority of the public network service is lower than that of the private network service, so that in case of the bandwidth resource shortage of the base station (for example, the RRC connection number of the public network service of the nth operator is greater than the third threshold value and/or the data transmission connection number of the public network service of the nth operator is greater than the fourth threshold value), the user experience of the private network user of the nth operator can be ensured by prohibiting the user access of the public network service of the nth operator.

In an implementation manner, in connection with fig. 4, the user access method provided in the embodiment of the present invention as shown in fig. 7 further includes S15 and S16.

And S15, when the base station determines that the residual bandwidth of the nth operator is smaller than or equal to the bandwidth demand, and operators with the residual bandwidth larger than the bandwidth demand exist in operators except the nth operator, allocating resources from any one of the operators with the residual bandwidth larger than the bandwidth demand in the operators except the nth operator.

It should be noted that allocating resources refers to allocating part of bandwidth resources in the residual bandwidth of the jth operator (which is an operator with a residual bandwidth greater than the bandwidth demand among operators other than the nth operator) to the nth operator, so that the bandwidth resources of the nth operator increase allocated bandwidth resources on the original basis, and the bandwidth resources of the corresponding jth operator reduce allocated bandwidth resources on the original basis.

In one implementation, when the bandwidth resources of the jth operator (also referred to as other operators) in the current unit time are insufficient, the base station preferentially reallocates the bandwidth resources allocated to the nth operator from the jth operator back to the jth operator, and if the bandwidth resources of the jth operator are still insufficient, allocates the resources from the other operators. Wherein j is different from n, and j is an integer.

In another embodiment, when the bandwidth resources of the current unit time are insufficient, the base station preferentially reallocates the bandwidth resources allocated to the nth operator from the jth operator back to the jth operator, if the bandwidth resources of the jth operator and the bandwidth resources of the nth operator are both insufficient, the base station preferentially allocates the resources to the nth operator from the other operators, and if the bandwidth resources of the jth operator are insufficient, the base station allocates the resources to the jth operator from the other operators.

In another implementation manner, when the bandwidth resources of the jth operator in the current unit time are insufficient, the base station preferentially reallocates the bandwidth resources allocated to the nth operator from the jth operator back to the jth operator, and if the bandwidth resources of the jth operator and the bandwidth resources of the nth operator are insufficient, preferentially allocates resources to the jth operator from other operators, and then allocates resources to the nth operator from the other operators.

In another embodiment, the base station sets different priorities for each of the operators (such as the operator a, the operator B and the operator C), so that when the residual bandwidths of the operator a and the operator B are smaller than or equal to the bandwidth demand and the residual bandwidth of the operator C is greater than the bandwidth demand, if the priority of the operator a is greater than the priority of the operator B, the resource is preferentially allocated to the operator a (resource is allocated from the public network carrier of the operator C), and after the resource is allocated by the operator a, if the residual resource is still available by the operator C, the resource is allocated to the operator B (resource is allocated from the public network carrier of the operator C).

S16, the base station distributes the allocated resources to the nth operator, and allows the new user of the kth private network service to access the core network equipment corresponding to the kth private network service in the current unit time.

It should be noted that, in an actual application, when the nth operator allocates resources from the other operators, the preset time (including at least one time) may be continued, and when the bandwidth resources of the other operators are insufficient, the allocated resources are reallocated to the other operators. When the remaining bandwidth of the nth operator is greater than the bandwidth demand after subtracting the resources allocated from the other operators, then reallocating the allocated resources to the other operators.

In the user access method provided by the embodiment of the invention, each carrier corresponds to one carrier, so that when the bandwidth resource of the carrier corresponding to the nth carrier is smaller than or equal to the bandwidth demand, whether the carrier corresponding to the other carrier has the residual bandwidth resource is required to be judged, and when the carrier corresponding to the other carrier has the residual bandwidth resource, the bandwidth resource is acquired from the other carrier, thereby ensuring the user experience of the private network user of the nth carrier and further improving the bandwidth resource utilization rate of the base station.

In an implementation manner, in connection with fig. 4, the user access method provided in the embodiment of the present invention as shown in fig. 8 further includes S17.

And S17, the base station determines that the residual bandwidth of the nth operator is smaller than or equal to the bandwidth demand, and when no operators with the residual bandwidth larger than the bandwidth demand exist in operators except the nth operator, the new user of the kth private network service is forbidden to access the core network equipment corresponding to the kth private network service in the current unit time.

It should be noted that, in the kth private network service of the nth operator in the current unit time, the user accessing the base station, the base station needs to continue to provide service for the user, and the new user requesting to access the kth private network service of the nth operator needs to prohibit access. When the residual bandwidth of each operator in the base station is smaller than or equal to the bandwidth demand, the number of users currently served by each operator is larger, so that resources cannot be allocated to the nth operator from other operators, and each operator is guaranteed to provide services for the respective users.

In one implementation, the target service further includes a public network service, in which case, in conjunction with fig. 4, the step S12 described above may be implemented through the step S120 as shown in fig. 9.

S120, the base station determines that the RRC connection number of the kth private network service of the nth operator is greater than a first threshold value, and/or the data transmission connection number of the kth private network service is greater than a second threshold value, and determines the bandwidth demand of the kth private network service of the nth operator in the current unit time according to a bandwidth demand formula and the network data of the target service of each operator in the N operators in the current unit time. Wherein, the bandwidth demand formula satisfies:

In one implementation manner, the network data further includes a residual bandwidth, in which case, in conjunction with fig. 4, the user access method provided in the embodiment of the present invention as shown in fig. 10 further includes S18 and S19.

And S18, the base station determines the bandwidth used by the nth operator in the current unit time according to the bandwidth formula and the network data of the target service of each operator in the N operators in the current unit time. Wherein, the bandwidth formula satisfies:

wherein ,W_NT Indicating the bandwidth used, RCC _PU Sigma RCC representing RRC connection number of public network service of nth operator in current unit time _Pr Indicating that all private network services of nth operator are in current unit timeIs defined as the sum of the number of RRC connections,

Where a=b-c, a represents the remaining bandwidth, b represents the nominal bandwidth of the nth operator, and c represents the bandwidth that the nth operator has used in the current unit time.
