Description

A user access method and access network equipment

technical field

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

Background technique

With the continuous evolution of the network, a large number of diversified industry application requirements have exploded. Network requirements for industry users have become an important deployment requirement for 5G. The fifth-generation mobile communication technology (5th-generation, 5G) network provides a variety of slicing modes, which can meet the needs of both consumers (customer to customer, 2C) and businesses (business to business, 2B). However, 5G equipment (5G base station) uses multiple antenna equipment such as 192 antennas, and the frequency band used by 5G equipment is 3.5GHz, and the coverage area is significantly smaller than that of equipment with frequency bands below 2GHz. The number of base stations (the number of base stations) has doubled. In this way, the high base station cost and the dense number of stations will lead to an exponential increase in network construction costs. Therefore, operators began to seek a solution in which multiple operators jointly build base stations and use the jointly built base stations for network deployment. Co-construction of base stations means that one base station can meet the needs of multiple operators, rather than deploying equipment of multiple operators in the same base station.

How to meet the access requirements of 2B (can be understood as private network) users and 2C (can be understood as public network) users of different operators in the case of limited resources after co-construction of shared base stations has become an urgent problem to be solved .

Contents of the invention

Embodiments of the present invention provide a user access method and access network equipment, which are used to handle the access demands of user terminals corresponding to private network services and public network services carried by shared base stations co-built by different operators based on capacity, The resource utilization rate of the shared base station is guaranteed.

In order to achieve the above object, embodiments of the present invention adopt the following technical solutions:

In the first aspect, a user access method is provided, which is applied to an access network device. The access network device provides carrier carriers corresponding to a plurality of operators one by one, and each carrier carrier is the carrier of the corresponding carrier. Provide support for public network services and private network services, including: obtaining the reserved traffic of each service carried by the access network equipment in the current unit time; when it is determined that there is a target service among all the services carried by the access network equipment, determine the type; the scheduled traffic of the target business is greater than the first preset percentage of the preset unit traffic of the target business, and the preset unit traffic is the preset traffic in a unit time; when the type of the target business is determined to be a public network business, the current Prohibit the access of new user terminals corresponding to the target service within a unit time; when it is determined that the type of the target service is a private network service, determine the target bandwidth required by the target service in the current unit time and correspond to the target service according to the reserved traffic of the target service The first remaining bandwidth of the carrier of the target operator, and according to the target bandwidth of the target service, determine whether to allow the new user terminal corresponding to the target service to access within the current unit time.

In the technical solution provided by the above-mentioned embodiments, after the access network device obtains the reserved traffic (that is, the traffic that needs to be used in the current unit time) of each service carried by it in the current unit time, it will first determine whether there is The target business whose preset traffic is greater than the first preset percentage of its preset unit traffic, because the traffic required by the target business will soon exceed the preset traffic for it in advance, if it is not determined in time whether to allow its corresponding new user terminal to access direct all access or prohibition will result in an unreasonable allocation of resources corresponding to the entire shared base station (for example, allocating most of the resources to a certain service of a certain operator, causing some users of other operators to be unable to use the service normally), The resource utilization rate is low, and the user experience will also be reduced. Therefore, it is necessary to determine in time whether the corresponding new user terminal can still access, so as to ensure that the corresponding resources of the entire shared base station can be fully utilized. The specific judgment method is: if the target service is a public network service, because it has a lower priority than the private network service, for the carrier carrier where the target service is located, it is necessary to give priority to ensuring the normal operation of the private network service. Considering that the resource demand of subsequent private network services suddenly increases, once the public network services exceed the preset value, the corresponding new user terminals are no longer allowed to access. If the target service is a private network service, because its priority is higher, it needs to be based on the required target bandwidth and the first remaining bandwidth of its corresponding target carrier carrier (that is, consider whether the target carrier carrier has sufficient resources to supply the new user terminal corresponding to the target service), and determine whether to allow the corresponding new user terminal to access. To sum up, from the technical solution provided by the embodiment of the present application, the access requests corresponding to all users carried by the shared base station co-built by multiple operators can be processed based on the capacity (allow access or not allow access), and super Whether the new user terminal corresponding to the stream service (reserved traffic is greater than the first preset percentage of the preset unit traffic) can be accessed is judged in a timely manner, ensuring a reasonable allocation of resources of the shared base station.

At present, because the single cost of 5G base stations is relatively high, and because of its small coverage area, the number of sites that need to be deployed per unit area is large, which results in the high cost of deploying 5G communication networks. Therefore, at present, multiple operators jointly build a shared base station to carry the service requirements of multiple operators. However, for co-built shared base stations, how to meet the access requirements of users corresponding to private network services of different operators and users corresponding to public network services is an urgent problem to be solved.

In view of the above problems, the embodiment of the present application provides a user access method, which can meet the access requirements of user terminals corresponding to different services carried by shared base stations (access network equipment) co-built by different operators based on capacity (traffic).

After the terminal 01 access network device 02 is connected to the access network device, it can access the corresponding operator's public network core network or private network core network through different core network devices 03 . Of course, there may be only one core network device 03 in practice, which can complete the functions of the above-mentioned multiple core network devices.

In the embodiment of the present application, the access network device 02 may be a global system for mobile communication (GSM), a base transceiver station in code division multiple access (CDMA), BTS), access network equipment (node B, NB) in wideband code division multiple access (WCDMA), access network equipment (evolved Node B, eNB) in long term evolution (Long Term Evolution, LTE) ), the eNB in the Internet of Things (Internet of Things, IoT) or narrowband Internet of Things (narrow band-internet of things, NB-IoT), the future 5G mobile communication network or the future evolution of the public land mobile network (public land mobile network, PLMN), the embodiment of the present invention does not impose any limitation on this.

Exemplarily, the terminal 01 in this embodiment of the present application may have different names, such as user equipment (userequipment, UE), access terminal, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile equipment, wireless communication equipment, vehicle user equipment, terminal agent or terminal device, etc. Specifically, it can be a mobile phone, tablet computer, desktop, laptop, handheld computer, notebook computer, ultra-mobile personal computer (ultra-mobile personalcomputer, UMPC), netbook, and cellular phone, personal digital assistant (personal digital assistant, PDA) ), augmented reality (augmented reality, AR)\virtual reality (virtual reality, VR) equipment and other equipment that can communicate with the base station, the embodiment of the present application does not specifically limit the specific form of the terminal.

It should be noted that in this application, an operator's core network corresponds to a public network and multiple private networks, public network services (2C services) refer to all services in a public network, and private network services (2B services) refer to a private network. All business in the network.

Exemplarily, as shown in 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 key capacity customization module 033 and an operator carrier bandwidth customization module 034 . Wherein, the service distribution requirement collection module 031 can collect the network data of the private network service or the public network service of the corresponding operator of the access network device 02 (such as a base station) to which it is connected. Network data may include: flow-related data of services corresponding to the network (average capacity/flow per target unit time (such as hour), maximum capacity/flow per target unit time (such as hour), service flow or number of users, 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 to it, and use the network data obtained by its corresponding service distribution demand collection module 031 to pass certain The calculation of determines whether the service in the actual scene corresponding to the network data mainly depends on capacity (traffic). Of course, if all the core networks correspond to the same core network device, the service dependency analysis module included therein can independently complete the above calculation process.

The key capacity customization module 033 can cooperate with the key capacity customization module 033 in other core network devices corresponding to the access network device 02 connected to it, and calculate different The agreed capacity per unit of time (preset unit traffic) recommended by the operator for public network services and private network services. Of course, if all the core networks correspond to the same core network device, the key capacity customization module included in it can independently complete the above calculation process. Exemplarily, taking the unit time as 1 second and the target unit time as 1 hour as an example, the preset unit traffic of public network services can be calculated by the following formula:

Among them, T ^PU _Y is the preset unit flow of the public network service, T ^PU _Max is the maximum hourly flow of the public network service, and T ^PU _mean is the hourly average flow of the public network service.

The preset unit traffic of the private network service can be calculated by the following formula:

Among them, T ^Pr _Y is the preset unit flow of the private network service, T ^Pr _Max is the maximum hourly flow of the private network service, and T ^Pr _mean is the hourly average flow of the public network service.

The operator carrier bandwidth customization module 034 can cooperate with the key capacity customization module 033 in other core network equipment corresponding to the access network equipment 02 connected to it, and according to the network data (capacity demand case), calculate the preset total bandwidth (initial bandwidth) of each carrier. Of course, if all the core networks correspond to the same core network device, the operator carrier bandwidth customization module included in it can independently complete the above calculation process.

Exemplarily, when the access network equipment corresponding to the core network equipment provides each operator with a corresponding operator carrier to carry corresponding public network services and private network services, the preset total bandwidth of any operator carrier can be Calculated according to the following formula:

Among them, W _NTi is the preset total bandwidth of the operator carrier i, T ^PU _Yi is the preset unit traffic of the public network service in the operator carrier i, T ^Pr _Yij is the preset value of the jth private network service in the operator carrier i Unit traffic, T ^PU _Yn is the preset unit traffic of the nth public network service carried by the access network device, T ^Pr _Ym is the preset unit traffic of the mth private network service carried by the access network device, floor is the Rounded down, W is the total bandwidth of the access network equipment.

Exemplarily, referring to FIG. 1 and referring to FIG. 2 , the access network device 02 includes a real-time traffic monitoring module 021 , a traffic judging module 022 , and a network load balancing module 023 . Wherein, the traffic real-time monitoring module 021 can collect the reservation traffic of private network services and public network services of an operator at a time granularity of unit time (1 second). The traffic judging module 022 can determine whether the subsequent network load balancing module 023 needs to deny or allow the access request of the user terminal of each service according to the traffic of each service collected by the real-time traffic monitoring module 021 and the corresponding reservation traffic of each service.

Exemplarily, taking a 5G communication network as an example, as shown in FIG. 3 , actual devices in the access network device 02 may include a radio frequency unit and a baseband processing unit. Among them, the radio frequency unit is connected to the baseband processing unit through the common public radio interface (common public radio interface, CPRI (eCRPI)), the public network core network (5GC1) of operator A, the public network core network (5GC2) of operator B, the operator Both the private network core network (5GC3) of the provider A and the private network core network (5GC4) of the operator B are connected to the baseband processing unit of the access network device 2 through the NG interface.

The 5G baseband processing unit includes a control plane (control plane, CP) and a user plane (user plane, UP). In the control plane, there are identification modules for private network core network and public network core network access of different operators (specifically, through PLMN (public land mobile network, public land mobile network), APN (access point name, access point name) ), DNN (Data network name, data network name) and other judgments), so as to realize the distinction between the public network core network and the private network core network under different operators. The above-mentioned real-time traffic monitoring module 021, traffic judging module 022, and network load balancing module 023 may also all be set in the CP.

5G radio frequency unit includes antenna unit, switch and transceiver. Among them, the transceiver includes digital up conversion (digital up conversion, DUC), digital to analog converter (digital to analog converter, DAC), transmitting antenna (transport, TX), receiving antenna (receive, RX), analog to digital converter ( analog to digital converter, ADC) and digital down conversion (digital down conversion, DDC).

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

Exemplarily, as shown in FIG. 3, when two operators (operator A and operator B) are connected to the access network device, when operator A initiates public network services or private network services, through The carrier of the first operator performs data transmission, and the user terminal of operator B can perform data transmission through the carrier of the second operator when initiating a private network service. Wherein, the first carrier includes a first transceiver (DUC1, DAC1, TX1, DDC1, ADC1, RX1), a first combiner, a switch, and an antenna unit; the second carrier includes a second transceiver (DUC2, DAC2, TX2, DDC2, ADC2, RX2), second combiner, switch and antenna unit.

Based on the content shown in FIGS. 1-3 above, the embodiment of the present application provides a user access method, which is applied to the above-mentioned access network device 02 . Referring to Figure 4, the method includes 401-407:

401. Acquire the scheduled traffic of each service carried by the access network device in the current unit time.

Exemplarily, in order to ensure timely processing of the access request of the user terminal based on the capacity, the unit time here may be one second. Of course, under the condition that technology permits in practice, it can also be a smaller unit time, which is not specifically limited here.

Exemplarily, step 401 can be executed by the aforementioned real-time traffic monitoring module in practice, and the records after data collection are as follows in Table 1:

Table 1

Among them, YY represents the year, MM represents the month, DD represents the day of the MM month, and HH:SS represents the hour, minute and second.

Optionally, as shown in Figure 5, because the technical solution provided by the embodiment of the present application is based on traffic to determine whether the user terminal of each service is accessible, and if the traffic required by each service itself is not large, it will not affect at all To jointly build and share the performance of the base station, this technical solution does not need to be implemented, so the core network device 03 also needs to perform the following steps before step 401:

S1. Obtain the average traffic per target unit time of each service carried by the access network device before the current unit time and during the preset time period that is busy.

Exemplarily, the target unit time may be 1 hour; in order to ensure that the collected data can reflect the traffic usage of each service carried by the access network equipment while saving computing resources, the above preset time period may be two consecutive weeks on Tuesday (any working day) and Sunday (any rest day). The busy time can be determined by the operator according to the traffic usage of its corresponding users. For example, it can be 9:00-11:00 and 14:00-17:00 on working days, and it can be 10:00-17 on non-working days: 00.

Exemplarily, step S1 is mainly executed by the service distribution requirement collection module 031 in the core network device 03 shown in FIG. 2 .

S2. Determine the large flow target unit time according to the average flow of each target unit time when all services are busy within the preset time period.

Exemplarily, when all services are busy within the preset period of time, the sum of the average traffic in the target target unit time accounts for a proportion of the maximum traffic that the access network device can carry in a target unit time that is greater than the third When the ratio is preset, the target unit time is determined to be the high flow target unit time.

S3. Determine whether the proportion of the quantity of the large traffic target unit time to the total target unit time corresponding to the busy time within the preset time period is greater than the second preset percentage.

When the quantity of the large-traffic target unit time accounts for the total target unit time corresponding to all busy hours, and is greater than the second preset percentage, execute S4; when the large-traffic target unit time accounts for the total target corresponding to all busy hours When the proportion of the unit time is not greater than the second preset percentage, execute S1.

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

S4. Send a corresponding instruction to the access network device to obtain the reserved traffic of each service carried by the access network device in the current unit time.

Because the traffic used by each business during the time of the high-traffic target unit time is relatively large, it can be considered that it is very dependent on the traffic, and if the high-traffic target unit time is busy, the proportion of the total target unit time exceeds a certain ratio , it indicates that each service carried by the access network device is relatively traffic-dependent, and corresponding instructions need to be sent to the access network device to make the access network device execute the technical solution provided in the embodiment of the present application.

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 equipment may not perform the above S3 step, and directly determine according to the proportion of the large traffic target unit time to the total target unit time corresponding to the busy time within the preset time period after the S2 step It only needs to execute step S1 or send a corresponding instruction to the core network device to make it execute step 401 . In addition, the proportion of the amount of high-traffic target unit time to the total target unit time corresponding to all busy hours is equal to the second preset percentage, which can be attributed to the amount of high-traffic target unit time accounting for the total target unit time corresponding to all busy hours The situation that the proportion of is greater than the second preset percentage can also be attributed to the fact that the proportion of the number of large traffic target unit time to the total target unit time corresponding to all busy hours is less than the second preset percentage, the corresponding example in Figure 5 In the above example, the proportion of the amount of target unit time attributed to large traffic to the total target unit time corresponding to all busy hours is less than the second preset percentage, but this application does not specifically limit this.

402. Determine whether there is a target service in all services carried by the access network device.

Wherein, the scheduled traffic of the target service is greater than the first preset percentage of the preset unit traffic of the target business, and the preset unit traffic is the preset traffic in a unit time, that is, the data calculated by the key capacity customization module in the above embodiment. Exemplarily, because it is necessary to reserve some emergency bearing capacity for the base station in practice, the first preset percentage here may be 95% (just an example, and may be any other feasible value in practice).

When it is determined that the target service exists, perform 403; when it is determined that there is no target service, perform 407.

It should be noted that the above-mentioned step 402 may not exist in practice. After step 401, when it is determined that there is a target service in all the services carried by the access network device, execute 403. When it is determined that there is no target service in all the services carried by the access network device Execute 407 during business.

403. Determine the type of the target service.

Wherein, the type of the target service may be a public network service or a private network service.

404. When it is determined that the type of the target service is a public network service, prohibit access of a new user terminal corresponding to the target service within the current unit time.

Because the public network service has a lower priority than the private network service, for the carrier carrier where the target service is located, it is necessary to give priority to ensuring the normal operation of the private network service, and it is necessary to consider the sudden increase in the resource demand of the subsequent private network service , so once the public network service exceeds the preset value, its corresponding new user terminal is no longer allowed to access.

Exemplarily, in reality, there is a user terminal that requires more traffic in the current unit time than in the previous unit time. In this case, the new user terminal can refer to the specific service corresponding to its newly added traffic; In the case that the user terminal corresponding to the network service or private network service in the previous unit time no longer accesses the network in the current unit time, in this case, the new user terminal can refer to an optional part of the user terminal in the current unit time As new user terminals, the number of user terminals remaining after the selection is the same as the number of user terminals in the previous unit time. Of course, there may be any other possible situations in practice (for example, user terminals belonging to the same service (public network service or private network service) have different priorities, and it is necessary to start from a part of user terminals with lower priorities according to the priority. Select "New User Terminal" in ), and select a new user terminal according to the specific situation.

Exemplarily, the prohibition here may be that the access network equipment rejects the service request of the user terminal; it may also be in any other feasible manner.

405. When it is determined that the type of the target service is a private network service, determine the target bandwidth required by the target service in the current unit time according to the reserved traffic of the target service.

Exemplarily, the target bandwidth can be calculated according to the following formula:

为目标业务的预约流量，

为公网载波中第k个公网业务的预约流量，

为专网载波中第m个专网业务的预约流量，W为接入网设备的总带宽。Among them, W ^w _NTadd is the target bandwidth of the target service,

is the booking traffic of the target business,

is the reserved traffic of the kth public network service in the public network carrier,

is the reserved traffic of the m-th private network service in the private network carrier, and W is the total bandwidth of the access network equipment.

406. According to the target bandwidth of the target service and the first remaining bandwidth of the target operator carrier corresponding to the target service, determine whether to allow the new user terminal corresponding to the target service to access within the current unit time.

Optionally, as shown in FIG. 6 , 406A1-406A2 are also included before step 406:

406A1. Calculate the first total bandwidth required by other services in the carrier of the target carrier according to the reserved traffic of services other than the target service carried on the carrier of the target carrier; the carrier of the target carrier is the carrier of the carrier corresponding to the target service .

Exemplarily, the first total bandwidth can be calculated according to the following formula:

为目标运营商载波l中公网业务的预约流量，

为目标运营商载波l中除目标业务以外的所有专网业务中第x个专网业务的预约流量，

为接入网设备承载的所有公网业务第k个公网业务的预约流量，

为接入网设备承载的所有专网业务中第m个专网业务的预约流量，W为接入网设备的总带宽。Wherein, W ^l _NT is the first total bandwidth,

is the reserved traffic of the public network service in carrier l of the target operator,

is the reserved traffic of the xth private network service in all private network services except the target service in carrier l of the target operator,

Reservation traffic for the kth public network service of all public network services carried by the access network equipment,

is the reserved traffic of the m-th private network service among all private network services carried by the access network equipment, and W is the total bandwidth of the access network equipment.

406A2. Calculate the first remaining bandwidth of the target operator carrier according to the first total bandwidth and the preset total bandwidth of the target operator carrier.

Specifically, the first remaining bandwidth is a difference between the preset total bandwidth and the first total bandwidth.

Exemplarily, as shown in FIG. 6, step 406 includes 4061-4066:

4061. Determine whether the target bandwidth is greater than the first remaining bandwidth.

When it is determined that the target bandwidth is less than or equal to the first remaining bandwidth, perform 4062; when it is determined that the target bandwidth is greater than the first remaining bandwidth, perform 4063.

It should be noted that the case where the target bandwidth is equal to the first remaining bandwidth can be attributed to the case where the target bandwidth is greater than the first remaining bandwidth, or it can be attributed to the case where the target bandwidth is smaller than the first remaining bandwidth. In the above-mentioned embodiments, it is attributed to the target The situation that the bandwidth is less than the second preset percentage of the first remaining bandwidth is only an example, and the present application does not specifically limit it.

In practice, step 4061 may not exist, and step 4063 is executed when the target bandwidth is determined to be greater than the first remaining bandwidth, and step 4062 is executed when the target bandwidth is determined to be less than or equal to the first remaining bandwidth.

4062. Allow the new user terminal corresponding to the target service to access within the current unit time.

Exemplarily, the permission here may be that the access network device allows the service request of the user terminal, establishes a corresponding connection, and issues a corresponding configuration; it may also be any other feasible manner.

为运营商载波o中第x个专网业务的预约流量，

为接入网设备承载的所有公网业务中第k个公网业务的预约流量，

为接入网设备承载的所有专网业务中第m个专网业务的预约流量，W为接入网设备的总带宽。Wherein, W ^o _NT is the second total bandwidth of operator carrier o (any one of other operator carriers),

is the reserved traffic of the xth private network service in carrier o of the operator,

is the reserved traffic of the kth public network service among all public network services carried by the access network equipment,

is the reserved traffic of the m-th private network service among all private network services carried by the access network equipment, and W is the total bandwidth of the access network equipment.

4064. Determine whether there are available carrier carriers in all other carrier carriers.

Wherein, the target bandwidth is less than or equal to the second remaining bandwidth of the available operator carrier.

When it is determined that there are available carrier carriers in all other carrier carriers, perform 4065; when it is determined that there is no available carrier carrier in all other carrier carriers, perform 4066.

In practice, the above step 4064 may not exist. When it is determined that there are available carrier carriers in all other carrier carriers, perform step 4065. When it is determined that there is no available carrier carrier in all other carrier carriers, perform step 4066. .

4065. Within the current unit time, after allocating resources corresponding to the second remaining bandwidth of the available operator carrier to the target operator carrier, allow a new user terminal corresponding to the target service to access.

The allocation of resources refers to that the access network equipment allocates the second remaining bandwidth of the available operator carrier to the target operator carrier, so that the bandwidth resources of the target operator carrier increase the allocated bandwidth resources on the original basis, correspondingly The bandwidth resources of the available carrier carriers are reduced on the basis of the original allocated bandwidth resources.

In an implementable manner, the access network device sets different priorities for each operator (such as operator A, operator B, and operator C), so that when a private network service of operator A And when a private network service of operator B needs to use resources from the available carrier carrier, if the priority of operator A is higher than that of operator B, the allocated resources are preferentially allocated to operator A's The operator's carrier where the private network service is located is used for access by new user terminals corresponding to the private network service. In addition, if there are multiple available operator carriers, resources are first allocated from the available operator carrier corresponding to the operator with a lower priority.

It should be noted that, in practical applications, when the access network device allocates the resources of the available carrier of the carrier to the carrier of the target carrier, after a certain period of time, the target service and its bandwidth requirements in the foregoing embodiments may be redone. It is determined that if the target operator carrier no longer needs additional resources, the resource is reallocated to an available operator carrier.

4066. Forbid the new user terminal corresponding to the target service from accessing within the current unit time.

Exemplarily, the prohibition here may be that the access network equipment rejects the service request of the user terminal; it may also be in any other feasible manner.

407. Allow user terminals corresponding to all services to access during the current unit time.

It should be noted that all the allowed access in the foregoing embodiments (allowing some new user terminals to access or allowing some user terminals to access) all refer to maintaining the current 5QI (5G QoS Identifier) (used to identify 5G If the Qos (Quality of Service, service quality)) remains unchanged, each corresponding user terminal is allowed to access.

Optionally, as shown in FIG. 7, when it is determined that there is a target service in all services carried by the access network device, the method further includes step 408 in addition to step 403:

408. Allow user terminals corresponding to services other than the target service among all services carried by the access network device to access within the current unit time.

In the technical solution provided by the embodiment of the present application, after the access network device acquires the reserved traffic (that is, the traffic that needs to be used in the current unit time) of each service carried by it in the current unit time, it will first determine whether There is a target business whose preset traffic is greater than the first preset percentage of its own preset unit traffic, because the traffic required by the target business will soon exceed the traffic preset for it in advance, if it is not determined in time whether to allow its corresponding new user terminal Access, direct all access or prohibition, will cause unreasonable allocation of resources corresponding to the entire shared base station (for example, most resources are allocated to a certain service of a certain operator, causing some users of other operators to be unable to use the service normally) , the resource utilization rate is low, and the user experience will also be reduced. Therefore, at this time, it is necessary to determine in time whether the corresponding new user terminal can still access, so as to ensure that the corresponding resources of the entire shared base station can be fully utilized. The specific judgment method is: if the target service is a public network service, because it has a lower priority than the private network service, for the carrier carrier where the target service is located, it is necessary to give priority to ensuring the normal operation of the private network service. Considering that the resource demand of subsequent private network services suddenly increases, once the public network services exceed the preset value, the corresponding new user terminals are no longer allowed to access. If the target service is a private network service, because its priority is higher, it needs to be based on the required target bandwidth and the first remaining bandwidth of its corresponding target carrier carrier (that is, consider whether the target carrier carrier has sufficient resources to supply the new user terminal corresponding to the target service), and determine whether to allow the corresponding new user terminal to access. In summary, according to the technical solution provided by the embodiment of the present application, the access requests corresponding to all users carried by the shared base station co-built by multiple operators can be processed based on the capacity (access is allowed or not allowed), and super Whether the new user terminal corresponding to the stream service (reserved traffic is greater than the first preset percentage of the preset unit traffic) can be accessed is judged in a timely manner, ensuring a reasonable allocation of resources of the shared base station.
