Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a user access method and an access network device.
Background
As networks continue to evolve, the needs of diverse industry applications have exploded tremendously. Network requirements for industry users have become an important deployment requirement for 5G. 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. However, the 5G device (5G base station) adopts multiple multi-array antenna devices such as 192 array elements, and the frequency band adopted by the 5G device is 3.5GHz, and the coverage range is obviously smaller than that of the devices with the frequency band of 2GHz or below, which results in a multiple increase of the number of stations (the number of base stations) in a unit area, so that the high base station cost and the intensive station building number will cause an exponential increase of the network building cost. 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 requirements of multiple operators, and does not concentrate the equipment of multiple operators on the same base station for deployment.
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 embodiment of the invention provides a user access method and access network equipment, which can meet access requirements of user terminals corresponding to different services borne by shared base stations (access network equipment) co-established by different operators based on capacity (flow).
In order to achieve the above purpose, the embodiment of the present invention adopts the following technical scheme:
in a first aspect, a user access method is provided, applied to an access network device, where the access network device provides support for public network services and private network services of multiple operators through a carrier, and the method includes: acquiring reserved traffic of each service carried by access network equipment in the current unit time; when determining that the first service exists in all the services carried by the access network equipment, calculating the sum of reserved flows of all the second services of which the service priority is smaller than or equal to that of the first service; the reserved flow of the first service is larger than a first preset percentage of a first preset unit flow of the first service, and the first preset unit flow is preset flow in unit time; and when the sum of the reserved flows of all the second services is smaller than the second preset unit flow corresponding to all the second services, allowing the new user terminal corresponding to the first service to access the access network equipment in the current unit time.
In the technical solution provided in the foregoing embodiment, after obtaining the reserved traffic of all the services carried by the access network device in the current unit time (i.e., the traffic that needs to be used in the current unit time), the access network device will first determine whether there is a first preset percentage of the reserved traffic of the first service that is greater than the preset unit traffic of the first service, and if there is a description that the traffic of the first service is about to exceed the preset unit traffic, it needs to determine in time whether a new user terminal corresponding to the first service can also be allowed to access the access network device. Then, because the public network service and the private network service exist in all the services borne by the access network, and the access of the user terminal corresponding to the service with the highest priority needs to be ensured as much as possible due to the different priorities of the two services, when the first service is determined to exist, the sum of reserved flows of all the second services with the service priority smaller than or equal to the first service needs to be calculated, and then the size relation between the sum of reserved flows of the second services and the second preset unit flow corresponding to all the second services is judged. When the sum of the reserved flows of the second services is determined to be smaller than the second preset unit flow corresponding to all the second services, the flow which is required by all the services with the current priority being smaller than or equal to the first service is considered to be not exceeding the reserved unit flow, and the unused flow share of the second service can be distributed to the first service on the basis that the priority is ensured to be higher than the requirement of the first service, so that the access network equipment can allow the new user terminal corresponding to the first service to be accessed. In summary, the technical solution provided by the embodiments of the present application may satisfy access requirements of user terminals corresponding to different services carried by shared base stations (access network devices) co-established by different operators based on capacity (traffic).
In a second aspect, an access network device is provided, where the access network device provides support for public network services and private network services of multiple operators through a carrier, and the access network device includes: the device comprises an acquisition module, a judgment module, a calculation module and a processing module; the acquisition module is used for acquiring the reserved flow of each service carried by the access network equipment in the current unit time; the computing module is used for computing the sum of reserved flows of all second services of which the service priority is smaller than or equal to that of the first service when the judging module determines that the first service exists in all services carried by the access network equipment; the reserved flow of the first service is larger than a first preset percentage of a first preset unit flow of the first service, and the first preset unit flow is preset flow in unit time; the processing module is further configured to allow the new user terminal corresponding to the first service to access the access network device in the current unit time when the judging module determines that the sum of the reserved flows of all the second services is smaller than a second preset unit flow corresponding to all the second services.
In a third aspect, an access network device is provided, where the access network device provides support for public network services and private network services of multiple operators through a carrier, and the access network device includes: memory, processor, bus and communication interface; the memory is used for storing computer execution instructions, and the processor is connected with the memory through a bus; when the access network device is running, the processor executes computer-executable instructions stored in the memory to cause the access network device to perform the user access method as provided in the first aspect.

Currently, because the single cost of the 5G base station is high, and because the coverage area of the 5G base station is small, the number of sites needing to be arranged in a unit area is large, and thus the cost of the 5G communication network needing to be deployed is high. Therefore, a shared base station is commonly built by a plurality of operators at present, and can bear the service demands of the operators. However, how to meet access requirements of users corresponding to private network services and users corresponding to public network services of different operators for co-established shared base stations is a problem to be solved.
In view of the above problems, an embodiment of the present application 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 capacity (traffic). 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 this application, an operator core network corresponds to a public network and a plurality of private networks, a public network service (2C service) refers to all services in a public network, and a private network service (2B service) refers to all services in a private network.
Illustratively, 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, and a critical capacity customization module 033. 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: traffic related data (average capacity/traffic per target unit time (e.g., hour), maximum capacity/traffic per target unit time (e.g., hour)), traffic or the number of users, etc. of traffic corresponding to the network.
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 capacity (traffic) by using the network data acquired by the corresponding service distribution demand collection module 031 in cooperation with the service dependency analysis module 032 in the other core network device corresponding to the access network device 02 connected to the service dependency analysis module. 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 critical capacity customizing module 033 is configured to calculate, through cooperation of the critical capacity customizing module 032 in other core network devices corresponding to the access network device 02 connected thereto, the contracted capacity per unit time (the first preset unit flow) recommended for the public network service and the private network service of different operators according to the network data acquired by the service distribution demand collecting module 031 corresponding to each critical capacity 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. For example, taking 1 second per unit time and 1 hour per unit time as an example, the preset unit flow of the public network service can be calculated by the following formula:
wherein T is PU Y For the first preset unit flow of the public network service, T PU Max T is the maximum flow of the public network service per hour PU mean Is the average flow per hour of the public network service.
The preset unit flow of private network service can be calculated by the following formula:
wherein T is Pr Y For the first preset unit flow of the private network service, T Pr Max T is the maximum flow of the private network service per hour Pr mean Is the average flow per hour of the public network service.
For example, referring to fig. 2, the access network device 02 includes a traffic real-time monitoring module 021, a traffic discriminating module 022, and a network load balancing module 023. The traffic real-time monitoring module 021 can collect reserved traffic of private network traffic and public network traffic of each operator according to time granularity of unit time (1 second). The flow judgment 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 flow of each service and the reserved flow corresponding to each service collected by the flow real-time monitoring module 021.
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 flow real-time monitoring module 021, the flow 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 and a transceiver. The 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 scheme provided by the invention, the access network device 02 only carries public network services and private network services of all operators through one carrier. The carrier wave comprises an uplink carrier wave and a downlink carrier wave, the communication link corresponding to the uplink carrier wave is composed of an antenna unit, a switch, RX, ADC, DDC and a 5G baseband processing unit in the figure 3, and the communication link corresponding to the downlink carrier wave is composed of an antenna unit, a switch, TX, DAC, DUC and a 5G baseband processing unit in the figure 3. When the user terminals corresponding to the operator A and the operator B initiate private network service or public network service, related data are transmitted through the communication links corresponding to the uplink carrier and the communication links corresponding to the blind carrier.
In the embodiment of the present application, the access network device 02 may be an access network device (base transceiver station, BTS) in a global system for mobile communications (global system for mobile communication, GSM), an access network device (base transceiver station, BTS) in 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 (evolutiond Node 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 this way by the embodiment of the present invention.
By way of example, the terminal 01 in the embodiments of the present application may have different names, 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, or the like, which may communicate with a base station, and the specific form of the terminal is not limited in the embodiments of the present application.
Based on the content shown in fig. 1-3, the embodiment of the present application provides a user access method, which is applied to the access network device 02. Referring to fig. 4, the method includes 401-407:
401. and acquiring the reserved flow of each service carried by the access network equipment in the current unit time.
Illustratively, to ensure timely handling of access requests of user terminals on a capacity basis, the unit time here 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, the step 401 may be performed 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 application determines whether the user terminal of each service is accessible based on the traffic, and if the traffic required by each service is not large, and does not affect the performance of the co-established and shared base station, the technical solution does not need to be executed, so before step 401, the core network device 03 further needs to execute the following steps:
s1, acquiring average flow of each service carried by access network equipment in each target unit time in busy hours in a preset time period before the current unit time.
Illustratively, the target unit time may be 1 hour; in order to save computing resources and ensure that the collected data can reflect traffic usage conditions of services carried by the access network device, the preset time period can be two consecutive weeks (all weekdays) and sundays (all holidays). 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 traffic distribution requirement collection module 031 in the core network device 03 shown in fig. 2.
S2, determining the large-flow target unit time according to the average flow of all the businesses in each target unit time in busy hours in a preset time period.
For example, when the sum of average flows of all services in a preset time period and in a target unit time in busy hours is larger than a third preset duty ratio, determining that the target unit time is a large-flow target unit time.
S3, judging whether the number of the large-flow target unit time is larger than a second 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.
When the number of the large-flow target unit time is larger than the second preset percentage, executing S4; and when the number of the large-flow target unit time is not larger than the second preset percentage, executing S1.
The second preset percentage may be, for example, 30%, or any other feasible number, and is not particularly limited herein.
S4, sending a corresponding instruction to the access network equipment so as to enable the access network equipment to acquire the reserved flow of each service carried by the access network equipment in the current unit time.
Because the flow used by each service is more in the time of the large-flow target unit time, the large-flow target unit time can be considered as very dependent on the flow, and if the duty ratio of the total target unit time number in the busy hour exceeds a certain ratio, the fact that each service carried by the access network equipment is relatively dependent on the flow is indicated, and a corresponding instruction needs to be sent to the access network equipment to enable the access network equipment to execute the technical scheme provided by the embodiment of the application.
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.
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 401 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 second 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 second 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 second preset percentage, which is taken as an example in the example corresponding to fig. 5, but the present application is not limited to this.
402. Judging whether a first service exists in all the services carried by the access network equipment.
The reserved flow of the first service is larger than a first preset percentage of a first preset unit flow of the first service. The first preset unit flow is preset flow in unit time, that is, data obtained by calculation of the key capacity customization module in the above embodiment.
Illustratively, the first preset percentage may be 95% (by way of example only, and may be any other feasible value in practice) because it is actually necessary to set aside a portion of the emergency-capable bearer capacity for the base station.
Executing 403 when it is determined that the first service exists; when it is determined that the first service does not exist, 404 is performed.
It should be noted that, in practice, step 402 may not exist, and after step 401, step 403 may be executed when it is determined that the first service exists in all the services carried by the access network device, and step 404 may be executed when it is determined that the first service does not exist in all the services carried by the access network device.
403. And calculating the sum of reserved traffic of all second services with service priority less than or equal to that of the first service.
When the first service is a private network service, the second service is other services except the first service in all services carried by the access network device; when the first service is a public network service, the second service is other public network services except the first service in all public network services borne by the access network equipment.
When the first service is a private network service, the sum of the actual flows of all the second services can be calculated according to the following formula:
wherein T is A now Is the sum of the actual flows of the second traffic,
reserved flow of kth public network service (N) carried by access network equipment>
Reserved flow of mth private network service in all private network services carried by access network equipment>
Reserving traffic for a first service; n is a positive integer, k is a positive integer, and m is a positive integer.
When the first service is a public network service, the sum of the actual flows of all the second services can be calculated according to the following formula:
wherein T is PU now Reserving traffic for a second serviceAnd, a step of, in the first embodiment,
reserved flow for kth public network service in all public network services (N) carried by access network equipment,/for the public network service>
Reserving traffic for a first service; n is a positive integer, and k is a positive integer.
404. And allowing the user terminals corresponding to all the services borne by the access network equipment to access the access network equipment in the current unit time.
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 practice, there is a flow that a certain user terminal needs in a current unit time is more than a previous unit time, and in this case, a new user terminal may refer to a specific service corresponding to the newly added flow; in practice, there is a case that a user terminal corresponding to a public network service or a private network service in a previous unit time is not connected to the network any more in the current unit time, and in this case, the new user terminal may refer to an optional part of the user terminals in the current unit time as a new user terminal, and the number of the remaining user terminals after the selection is the same as the number of the user terminals in the previous unit time. Of course, in reality, there may be any other possible situations (for example, the priorities corresponding to the user terminals belonging to the same service (public network service or private network service) are different, and a "new user terminal" needs to be selected from a part of user terminals with low priorities according to the priority, so that a new user terminal is specifically selected according to the specific situation.
405. And judging whether the sum of the reserved flows of all the second services is larger than a second preset unit flow corresponding to all the second services.
When the first service is a public network service, the second service is other public network services except the first service in all public network services borne by the access network equipment; the second preset unit flow is the sum of the first preset unit flows of all the second services in unit time. When the first service is a private network service, the second service is other services except the first service in all services borne by the access network equipment; the second preset unit flow is the difference value of the maximum flow which can be borne by the access network equipment in unit time minus the reserved flow of the first service.
Executing 406 when it is determined that the sum of the reserved flows of all the second services is greater than a second preset unit flow corresponding to all the second services; when it is determined that the sum of the reserved flows of all the second services is not greater than the second preset unit flow corresponding to all the second services, 407 is performed.
When the first service is private network service, because the priority of the private network service is higher, the service use of the private network user needs to be guaranteed preferentially, so as long as the base station itself can bear the load, the use of the private network service needs to be met continuously, i.e. a new user terminal corresponding to the private network service is allowed to be accessed (407); the access of the new user terminal corresponding to the private network service is not allowed only if the base station itself cannot carry too much traffic (step 406).
When the first service is a public network service, because the service priority is lower, the public network service is considered on the basis of guaranteeing the use of the private network service, for the superfluid public network service (the reserved flow is larger than the first preset percentage of the first preset unit flow), only if the flow occupied by other public network services (the reserved flow sum) is not larger than the reserved flow sum (the first preset unit flow sum), the user terminal corresponding to the public network service can be allowed to access (407), and when the flow occupied by other public network services is larger than the reserved flow sum (the first preset unit flow sum), the new user terminal corresponding to the public network service is forbidden to access (406).
In practice, step 405 may not be present, and step 406 or step 407 may be performed directly according to the relationship between the sum of reserved flows of all the second services and the second preset unit flow corresponding to all the second services after step 403. In addition, the sum of the reserved flows of all the second services is equal to the second preset unit flow corresponding to all the second services, which may be the case where the sum of the reserved flows of all the second services is greater than the second preset unit flow corresponding to all the second services, or the case where the sum of the reserved flows of all the second services is less than the second preset unit flow corresponding to all the second services, which is exemplified in the example corresponding to fig. 4 by the fact that the sum of the reserved flows of all the second services is less than the second preset unit flow corresponding to all the second services, but the present application is not limited thereto specifically.
406. And prohibiting the new user terminal corresponding to the first service from accessing the access network equipment in the current unit time.
Illustratively, the prohibiting may be that the access network device refuses the service request of the user terminal; but may be any other feasible way.
When the sum of the reserved flows of the second services is determined to be greater than the second preset unit flow corresponding to all the second services, it can be considered that the required flows of all the services with the current priority being less than or equal to the first service have exceeded the reserved unit flow, and the access network device can not allow the new user terminal corresponding to the first service (i.e. the user terminal of which the first service is newly added in the current unit time relative to the previous unit time) to be accessed on the basis that the priority is ensured to be higher than the requirement of the first service.
407. And allowing the new user terminal corresponding to the first service to access the access network equipment in the current unit time.
The permission here may be that the access network device allows the service request of the user terminal and establishes a response connection and issues a response configuration; but may be any other feasible way.
Optionally, referring to fig. 6, when it is determined that the first service exists in all services carried by the access network device, the method includes, in addition to step 403:
408. and allowing the user terminals corresponding to the services except the first service in all the services borne by the access network equipment to be accessed in the current unit time.
In the technical solution provided in this embodiment of the present application, after obtaining reserved traffic of all the services carried by the access network device in the current unit time (i.e., traffic that needs to be used in the current unit time), the access network device will first determine whether there is a first preset percentage of the reserved traffic of the first service that is greater than the preset unit traffic of the first service, and if there is a description that the traffic of the first service is about to exceed the preset unit traffic, it needs to determine in time whether a new user terminal corresponding to the first service can also be allowed to access the access network device. Then, because the public network service and the private network service exist in all the services borne by the access network, and the access of the user terminal corresponding to the service with the highest priority needs to be ensured as much as possible due to the different priorities of the two services, when the first service is determined to exist, the sum of reserved flows of all the second services with the service priority smaller than or equal to the first service needs to be calculated, and then the size relation between the sum of reserved flows of the second services and the second preset unit flow corresponding to all the second services is judged. When the sum of the reserved flows of the second services is determined to be smaller than the second preset unit flow corresponding to all the second services, the flow which is required by all the services with the current priority being smaller than or equal to the first service is considered to be not exceeding the reserved unit flow, and the unused flow share of the second service can be distributed to the first service on the basis that the priority is ensured to be higher than the requirement of the first service, so that the access network equipment can allow the new user terminal corresponding to the first service to be accessed. In summary, the technical solution provided by the embodiments of the present application may satisfy access requirements of user terminals corresponding to different services carried by shared base stations (access network devices) co-established by different operators based on capacity (traffic).
