Description

User access method and access network device

Technical Field

The present invention relates to the field of communication technology, and in particular to a user access method and access network equipment.

Background Art

The fifth-generation mobile communication technology (5th-generation, 5G) network provides a variety of slicing modes that can meet the needs of both consumers (customer to customer, 2C) and enterprises (business to business, 2B).

The transceiver equipment in the 5G network (such as access network equipment) is usually multi-antenna equipment, such as 64 transmitter and receiver (TR) equipment, which leads to extremely high network construction costs. Therefore, operators began to seek a solution for multiple operators to jointly build base stations and use the jointly built base stations for network deployment. Jointly building base stations means that one base station can meet the needs of multiple operators, not that the equipment of multiple operators is concentrated in the same base station.

How to meet the access demands of 2B (which can be understood as private network) and 2C (which can be understood as public network) users of different operators as much as possible under the condition of limited resources after the shared base stations are jointly built has become an urgent problem to be solved.

Summary of the invention

The present invention provides a user access method and access network equipment, which solves the problem of how to meet the access demands 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 limited resources after the shared base station is jointly built, which has become an urgent problem to be solved.

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

In a first aspect, an embodiment of the present invention provides a user access method, which is applied to an access network device, and the access network device provides support for a public network service and a private network service of an operator through a carrier, including: obtaining network data of a target service of each operator in N operators in the current unit time. Wherein, the target service includes K private network services, and the network data includes at least the number of RRC connections and the number of data transmission connections, N is an integer greater than or equal to 2, and K is an integer greater than or equal to 1. When it is determined that the number of RRC connections of the kth private network service of the nth operator is greater than the first threshold, and/or the number of data transmission connections of the kth private network service is greater than the second threshold, the bandwidth demand of the kth private network service in the current unit time is determined according to the network data of the N operators. Wherein, n∈[1,N], and n is an integer, k∈[1,K], and k is an integer. When it is determined that the remaining bandwidth of the nth operator is greater than the bandwidth demand, a new user of the kth private network service is allowed to access the core network device corresponding to the kth private network service in the current unit time.

It can be seen that the access network device can determine whether the number of RRC connections of the kth private network service of the nth operator is greater than the first threshold, and/or whether the number of data transmission connections of the kth private network service is greater than the kth private network service of the second threshold, based on the network data of the current unit time, so as to determine whether the 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 it is determined that the number of RRC connections of the kth private network service of the nth operator is greater than the first threshold, and/or the number of data transmission connections of the kth private network service is greater than the second threshold, it means that there are many new users requesting access to the kth private network service in the current unit time, so it is necessary to determine the bandwidth demand of the kth private network service in the current unit time. When it is determined that the remaining bandwidth of the nth operator is greater than the bandwidth demand, the new user of the kth private network service is allowed to access the core network device corresponding to the kth private network service in the current unit time. This solves the problem of how the shared base stations after co-construction can meet the access demands of 2B (which can be understood as private network) and 2C (which can be understood as public network) users of different operators as much as possible under the condition of limited resources.

In a second aspect, the present invention provides an access network device, which provides support for public network services and private network services of an operator through a carrier, and the access network device includes various modules for executing the user access method of the first aspect.

Specifically, the access network device includes: an acquisition unit and a processing unit. The acquisition unit is used to acquire the network data of the target service of each operator in the N operators in the current unit time; wherein the target service includes K private network services, and the network data includes at least the number of RRC connections and the number of data transmission connections, N is an integer greater than or equal to 2, and K is an integer greater than or equal to 1. The processing unit is used to determine that when the number of RRC connections of the kth private network service of the nth operator acquired by the acquisition unit is greater than the first threshold, and/or the number of data transmission connections of the kth private network service acquired by the acquisition unit is greater than the second threshold, determine 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. Wherein, n∈[1,N], and n is an integer, k∈[1,K], and k is an integer. The processing unit is also used to determine that when the remaining bandwidth of the nth operator is greater than the bandwidth demand, allow new users of the kth private network service to access the core network device corresponding to the kth private network service in the current unit time.

In a third aspect, the present invention provides an access network device, comprising: a communication interface, a processor, a memory, and a bus; the memory is used to store computer-executable instructions, and the processor and the memory are connected via the bus. When the access network device is running, the processor executes the computer-executable instructions stored in the memory, so that the access network device executes the user access method provided in the first aspect above.

In a fourth aspect, the present invention provides a computer-readable storage medium, comprising instructions. When the instructions are executed on a computer, the computer executes the user access method provided in the first aspect.

In a fifth aspect, the present invention provides a computer program product. When the computer program product runs on a computer, the computer executes the user access method as described in the design mode of the first aspect.

It should be noted that the above computer instructions may be stored in whole or in part on a first computer-readable storage medium, wherein the first computer-readable storage medium may be packaged together with the processor of the access network device, or may be packaged separately from the processor of the access network device, which is not limited in the present invention.

The description of the second, third, fourth and fifth aspects of the present invention can refer to the detailed description of the first aspect; and the beneficial effects of the description of the second, third, fourth and fifth aspects can refer to the beneficial effect analysis of the first aspect, which will not be repeated here.

In actual implementation, these devices or functional modules may appear with other names. As long as the functions of each device or functional module are similar to those of the present invention, they fall within the scope of the claims of the present invention and their equivalent technologies.

DETAILED DESCRIPTION

The embodiments of the present invention are described below in conjunction with the accompanying drawings.

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish between identical items or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order.

In response to the above problems, an embodiment of the present invention provides a user access method, which can meet the access demands of user terminals corresponding to different services carried by shared base stations (access network devices) jointly built by different operators based on the number of radio resource control (RRC) connections and the number of data transmission connections (indicating the number of RRC connections with data transmission). The method is applied to the system architecture shown in Figure 1, which may include: terminal 01, 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 corresponds to an operator core network (private network core network (supporting 2B services) or public network core network (supporting 2C services)). Exemplarily, as shown in Figure 1, 03-1 can correspond to the public network core network of operator A, 03-2 can correspond to the private network core network of operator A, 03-3 can correspond to the public network core network of operator B, and 03-4 can correspond to the private network core network of operator B. After the terminal 01 accesses the network device 02 and is connected to the access network device, it can access the public network core network or private network core network of the corresponding operator through different core network devices 03. Of course, in practice, there may be only one core network device 03, which can complete the functions of the above-mentioned multiple core network devices.

It should be noted that, in the present invention, public network services (2C services) refer to all services in the public network, and private network services (2B services) refer to all services in the private network.

Exemplarily, as shown in FIG. 2 , the functional modules in the core network device 03 may include a service distribution demand collection module 031, a service dependency analysis module 032, a key user number parameter customization module 033, and an operator carrier bandwidth customization module 034. Among them, the service distribution demand collection module 031 may collect network data of the private network service or public network service of the corresponding operator of the access network device 02 (e.g., base station) to which it is connected. The network data may include: relevant data of the service corresponding to the network (average number of RRC connections per unit time (e.g., hour)/average number of RRC connections with data transmission, maximum number of RRC connections per unit time (e.g., hour)/maximum number of RRC connections with data transmission), traffic or number of users of the service, etc.

The service dependency analysis module 032 can cooperate with the service dependency analysis module 032 in other core network devices corresponding to the access network device 02 connected thereto, and use the network data obtained by the corresponding service distribution demand collection module 031 to determine through certain calculations whether the service in the actual scenario corresponding to the network data mainly depends on the number of RRC connections and the number of RRC connections with data transmission. Of course, if all core networks correspond to the same core network device, the service dependency analysis module included therein independently completes the above calculation process.

The key user number parameter customization module 033 is used to calculate the agreed RRC connection number (first threshold) and the agreed data transmission RRC connection number (second threshold) per target unit time recommended for the public network services and private network services of different operators according to the network data obtained by their respective corresponding service distribution demand collection modules 031 through the key user number parameter customization modules 033 in other core network devices corresponding to the access network device 02 connected thereto. Of course, if all core networks correspond to the same core network device, the key capacity customization module included therein independently completes the above calculation process.

For example, taking the unit time as 1 second and the target unit time as 1 hour, the first threshold and the second threshold of the private network service can be calculated by the following formula:

Indicates the agreed number of users accessing the private network with data transmission per second.

Indicates the maximum number of RRC connections per hour in the private network.

Indicates the average number of RRC connections per hour in the private network.

Indicates the maximum number of RRC connections with data transmission per hour in the private network.

Indicates the average number of RRC connections with data transmission per hour in the private network.

The operator carrier bandwidth customization module 034 is used to obtain the number of RRC connections and the number of RRC connections with data transmission of different operators in the area where the base station is to be deployed, and determine the initial bandwidth of each carrier.

The initial bandwidth satisfies

Among them, 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 means that the calculated value is rounded down.

Exemplarily, as shown in FIG. 2 , the access network device 02 includes a user number real-time monitoring module 021, a user number determination module 022, and a network load balancing module 023. Among them, the user number real-time monitoring module 021 can collect the number of RRC connections and the number of RRC connections with data transmission of the private network services and public network services of each operator at a time granularity of unit time (1 second). The user number determination module 022 can determine whether the subsequent network load balancing module 023 needs to reject or allow the access request of the user terminal of each service based on the number of RRC connections and the number of RRC connections with data transmission collected by the service distribution demand collection module 031.

Exemplarily, taking the 5G communication network as an example, as shown in FIG3 , the actual 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 via a common public radio interface (CPRI (eCRPI)), and the public network core network (5GC1) of operator A, the public network core network (5GC2) of operator B, the private network core network (5GC3) of operator A, and the private network core network (5GC4) of operator B are all connected to the baseband processing unit of the access network device 2 via an NG interface.

The 5G baseband processing unit includes a control plane (CP) and a user plane (UP). The control plane contains an identification module for the private core network and public core network of different operators (specifically, it can be judged by PLMN (public land mobile network), APN (access point name), DNN (data network name), etc.), so as to distinguish the public core network and private core network under different operators. The above-mentioned user number real-time monitoring module 021, user number determination module 022, and network load balancing module 023 can also be set in the CP.

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

Specifically, in the technical solution provided by the present invention, the access network device 02 allocates a carrier to each operator to carry the public network services and private network services of the 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, switch, RX, ADC, DDC, and 5G baseband processing unit in Figure 3, and the communication link corresponding to the downlink carrier is composed of the antenna unit, switch, TX, DAC, DUC, and 5G baseband processing unit in Figure 3.

For example, as shown in FIG3, when two operators (operator A and operator B) are connected to the access network device, the user terminal of operator A can transmit through the first carrier when initiating a private network service or a public network service, and the user terminal of operator B can transmit through the second carrier when initiating a private network service or a public network service. The first carrier includes 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 a global system for mobile communication (GSM), an access network device (base transceiver station, BTS) in code division multiple access (CDMA), an access network device (node B, NB) in wideband code division multiple access (WCDMA), an access network device (evolved Node B, eNB) in long term evolution (LTE), an eNB in the internet of things (IoT) or 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 (PLMN), and the embodiment of the present invention does not impose any restrictions on this.

For example, the terminal 01 in the embodiment of the present invention has different names, such as user equipment (UE), access terminal, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile device, wireless communication device, vehicle user equipment, terminal agent or terminal device, etc. It can be a mobile phone, tablet computer, desktop, laptop, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phone, personal digital assistant (PDA), augmented reality (AR)\virtual reality (VR) equipment and other equipment that can communicate with the base station. The embodiment of the present invention does not impose any special restrictions on the specific form of the terminal.

In conjunction with the communication system shown in FIG. 1 , the user access method provided by the embodiment of the present invention is introduced by taking the access network device 02 as a base station as an example.

As shown in FIG4 , the user access method provided in the embodiment of the present invention is applied to a base station, and the base station provides support for a public network service and a private network service of an operator through one carrier, including:

S11. The base station obtains network data of a target service of each operator among N operators in a current unit time, wherein the target service includes K private network services, the network data includes at least the number of RRC connections and the number of data transmission connections, N is an integer greater than or equal to 2, and K is an integer greater than or equal to 1.

For example, in order to ensure timely processing of the access request of the user terminal based on the RRC connection number and the data transmission connection number (also referred to as the RRC connection number with data transmission), the unit time here may be one second. Of course, under the actual technical conditions, it may also be a smaller unit time, which is not specifically limited here.

For example, in practice, S11 may be executed by the aforementioned real-time traffic monitoring module, and the data collected is recorded as shown in Table 1 below:

Table 1

Among them, YY represents the year, MM represents the month, DD represents the day of the month MM, and HH:SS represents hours, minutes and seconds.

Optionally, as shown in FIG. 5, because the technical solution provided in the embodiment of the present invention is based on the number of RRC connections and the number of RRC connections with data transmission to determine whether the user terminal of each service is accessible, and if the number of RRC connections required by each service and the number of RRC connections with data transmission are not large, and the performance of the co-built and shared base station is not affected at all, there is no need to execute the technical solution, so before step S11, the core network device 03 also needs to perform the following steps:

S1. The core network device 03 obtains the average number of RRC connections and the average number of RRC connections with data transmission for each target unit time that is busy during a preset time period before the current unit time for each service carried by the base station.

Exemplarily, the target unit time may be 1 hour; in order to save computing resources while ensuring that the collected data can reflect the number of RRC connections of each service carried by the base station and the usage of the number of RRC connections with data transmission, the preset time period may be Tuesdays (any working day) and Sundays (any rest day) for two consecutive weeks. The busy hours may be determined by the operator based on the traffic usage of its corresponding users, for example, on working days it may be 9:00-11:00 and 14:00-17:00, and on non-working days it may be 10:00-17:00.

Exemplarily, 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 the high-traffic target unit time according to the average number of RRC connections per target unit time that is busy for all services within a preset time period and the average number of RRC connections with data transmission.

Exemplarily, when the sum of the average number of RRC connections within a target unit time in the busy hour of all services within a preset time period accounts for a proportion of the maximum number of RRC connections that the base station can carry within a target unit time that is greater than a third preset proportion, the target unit time is determined to be a high-traffic target unit time.

When the sum of the average number of RRC connections with data transmission within a target unit time in the busy hour of all services within the preset time period accounts for a proportion of the maximum number of RRC connections with data transmission that the base station can carry within a target unit time that is greater than the fourth preset proportion, the target unit time is determined to be a high-traffic target unit time.

S3. The core network device 03 determines whether the proportion of the number of high-flow target unit times to the total number of target unit times corresponding to the busy time in the preset time period is greater than a preset percentage.

When the proportion of the number of high-flow target unit times to the total target unit times corresponding to all busy hours is greater than the preset percentage, execute S4; when the proportion of the number of high-flow target unit times to the total target unit times corresponding to all busy hours is not greater than the preset percentage, execute S1.

Exemplarily, the preset percentage may be 30%, or any other feasible value, which is not specifically limited here.

S4. The core network device 03 sends a corresponding instruction to the base station so that it obtains the number of RRC connections and the number of RRC connections with transmission for each service carried by the base station in the current unit time.

Because the traffic used by various services during the time period of high-traffic target unit time is relatively large, it can be considered that it is very dependent on the number of RRC connections and the number of RRC connections with transmission. If the proportion of high-traffic target unit time to the total target unit time during busy hours exceeds a certain ratio, it indicates that the services carried by the base station are relatively dependent on the number of RRC connections and the number of RRC connections with transmission, and corresponding instructions need to be sent to the base station to enable the base station to execute the technical solution provided by the embodiment of the present invention.

Exemplarily, the above steps S2-S4 are executed 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 above-mentioned step S3. After step S2, it can directly determine whether to execute step S1 or send a corresponding instruction to the core network device to execute step S12 according to the proportion of the number of large traffic target unit times to the total target unit times corresponding to the busy hours in the preset time period. In addition, the proportion of the number of large traffic target unit times to the total target unit times corresponding to all busy hours is equal to the preset percentage, which can be attributed to the situation that the proportion of the number of large traffic target unit times to the total target unit times corresponding to all busy hours is greater than the preset percentage, or it can be attributed to the situation that the proportion of the number of large traffic target unit times to the total target unit times corresponding to all busy hours is less than the preset percentage. The example corresponding to Figure 5 takes the situation that the proportion of the number of large traffic 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 present invention does not make specific restrictions on this.

S12. When the base station determines that the number of RRC connections of the kth private network service of the nth operator is greater than the first threshold, and/or the number of data transmission connections of the kth private network service is greater than the second threshold, the bandwidth demand of the kth private network service in the current unit time is determined according to the network data of the N operators. Where n∈[1,N], and n is an integer, and k∈[1,K], and k is an integer.

第二阈值为

从而可以防止接入的用户对应的RRC连接数过多时，导致基站无法让新的用户接入的问题。Optionally, the first threshold may be

The second threshold is

This can prevent the problem that the base station cannot allow new users to access when there are too many RRC connections corresponding to the accessed users.

S13. When the base station determines that the remaining bandwidth of the nth operator is greater than the bandwidth demand, a new user of the kth private network service is allowed to access the core network device corresponding to the kth private network service in the current unit time.

As can be seen from the above, the base station can determine whether the number of RRC connections of the kth private network service of the nth operator is greater than the first threshold, and/or whether the number of data transmission connections of the kth private network service is greater than the kth private network service of the second threshold according to the network data of the current unit time, thereby determining whether the 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 number of RRC connections of the kth private network service of the nth operator is greater than the first threshold, and/or the number of data transmission connections of the kth private network service is greater than the second threshold, it means that there are many new users requesting access to the kth private network service in the current unit time, so it is necessary to determine the bandwidth demand of the kth private network service in the current unit time. When the base station determines that the remaining bandwidth of the nth operator is greater than the bandwidth demand, the new user of the kth private network service is allowed to access the core network device corresponding to the kth private network service in the current unit time.

In an achievable manner, when the target service also includes a public network service, in this case, in combination with FIG. 4 , as shown in FIG. 6 , the user access method provided by the embodiment of the present invention further includes S14 .

S14. When the base station determines that the number of RRC connections of the public network service of the nth operator is greater than the third threshold, and/or the number of data transmission connections of the public network service of the nth operator is greater than the fourth threshold, new users of the public network service of the nth operator are prohibited from accessing the core network equipment corresponding to the public network service of the nth operator in the current unit time.

Exemplarily, taking the unit time as 1 second and the target unit time as 1 hour as an example, the third threshold and the fourth threshold of the public network service can be calculated by the following formula:

第四阈值为

The fourth threshold is

This can prevent the problem that the base station cannot allow new users to access when there are too many RRC connections corresponding to the accessed users.

In an implementable manner, when it is determined that the number of RRC connections 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 the number of RRC connections 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 new users of K private network services. Among them, normal access refers to maintaining the current 5QI (5G QoS Identifier) (used to identify 5G QoS (Quality of Service)) unchanged, allowing new user terminals corresponding to each service to access.

It should be noted that in actual applications, since the priority of public network services is lower than that of private network services, when the bandwidth resources of the base station are tight (such as: the number of RRC connections of the public network services of the nth operator is greater than the third threshold, and/or the number of data transmission connections of the public network services of the nth operator is greater than the fourth threshold), the user access of the public network services of the nth operator can be prohibited, thereby ensuring the user experience of the private network users of the nth operator.

In one achievable manner, in combination with FIG. 4 , as shown in FIG. 7 , the user access method provided by the embodiment of the present invention further includes S15 and S16.

S15. When the base station determines that the remaining bandwidth of the nth operator is less than or equal to the bandwidth demand, and there is an operator other than the nth operator whose remaining bandwidth is greater than the bandwidth demand, resources are allocated from any operator other than the nth operator whose remaining bandwidth is greater than the bandwidth demand.

It should be noted that resource allocation means that the base station allocates part of the remaining bandwidth of the j-th operator (an operator other than the n-th operator whose remaining bandwidth is greater than the bandwidth demand) to the n-th operator, so that the bandwidth resources of the n-th operator are increased by the allocated bandwidth resources on the original basis, and the bandwidth resources of the j-th operator are correspondingly reduced by the allocated bandwidth resources on the original basis.

In an implementable manner, when the bandwidth resources of the jth operator (also referred to as other operators) are insufficient in the current unit time, the base station will preferentially reallocate the bandwidth resources allocated from the jth operator to the nth operator back to the jth operator. If the bandwidth resources of the jth operator are still insufficient, resources will be allocated from other operators. Wherein, j is different from n, and j∈[1, N], and j is an integer.

In another feasible manner, when the bandwidth resources of the j-th operator are insufficient in the current unit time, the base station will prioritize reallocating the bandwidth resources allocated from the j-th operator to the n-th operator back to the j-th operator. If the bandwidth resources of the j-th operator and the bandwidth resources of the n-th operator are both insufficient, the base station will prioritize allocating resources from other operators to the n-th operator. If the bandwidth resources of the j-th operator are still insufficient, resources will be allocated from other operators to the j-th operator.

In another feasible manner, when the bandwidth resources of the j-th operator are insufficient in the current unit time, the base station will prioritize reallocating the bandwidth resources allocated from the j-th operator to the n-th operator back to the j-th operator. If the bandwidth resources of the j-th operator and the bandwidth resources of the n-th operator are both insufficient, the base station will prioritize allocating resources from other operators to the j-th operator, and then allocate resources from other operators to the n-th operator.

In another feasible manner, the base station sets different priorities for each operator (such as operator A, operator B and operator C), so that when the remaining bandwidth of operator A and operator B is less than or equal to the bandwidth demand, and the remaining bandwidth of operator C is greater than the bandwidth demand, if the priority of operator A is greater than the priority of operator B, resources are first allocated to operator A (resources are allocated from the public network carrier of operator C). After operator A has allocated resources, if operator C still has remaining resources, resources are allocated to operator B (resources are allocated from the public network carrier of operator C).

S16. The base station allocates the allocated resources to the nth operator, and allows new users of the kth private network service to access the core network device corresponding to the kth private network service in the current unit time.

It should be noted that in actual applications, when the nth operator allocates resources from other operators, it can continue for a preset time (including at least one moment), and when the bandwidth resources of other operators are insufficient, the allocated resources are reallocated to other operators. When the remaining bandwidth of the nth operator is greater than the bandwidth demand after deducting the resources allocated from other operators, the allocated resources are reallocated to other operators.

In the user access method provided by the embodiment of the present invention, each operator corresponds to a carrier. Therefore, when the bandwidth resources of the carrier corresponding to the nth operator are less than or equal to the bandwidth demand, it is necessary to determine whether the carriers corresponding to other operators have remaining bandwidth resources. When the carriers corresponding to other operators have remaining bandwidth resources, the bandwidth resources are retrieved from other operators to ensure the user experience of the private network users of the nth operator, thereby further improving the bandwidth resource utilization rate of the base station.

In one achievable manner, in combination with FIG. 4 , as shown in FIG. 8 , the user access method provided by the embodiment of the present invention further includes S17 .

S17. When the base station determines that the remaining bandwidth of the nth operator is less than or equal to the bandwidth demand, and there is no operator other than the nth operator whose remaining bandwidth is greater than the bandwidth demand, new users of the kth private network service are prohibited from accessing the core network device corresponding to the kth private network service in the current unit time.

It should be noted that the base station needs to continue to provide services to users who have accessed the base station in the kth private network service of the nth operator in the current unit time, while new users who request to access the kth private network service of the nth operator need to be prohibited from accessing. When the remaining bandwidth of each operator in the base station is less than or equal to the bandwidth demand, it means that the number of users currently served by each operator is large, so resources cannot be allocated from other operators to the nth operator, so as to ensure that each operator provides services to its own users.

In one achievable manner, the target service also includes a public network service. In this case, in combination with FIG. 4 , the above step S12 can be implemented through step S120 as shown in FIG. 9 .

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

Wherein, a=b-c, a represents the remaining bandwidth, b represents the rated bandwidth of the nth operator, and c represents the bandwidth used by the nth operator in the current unit time.
