Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a user access method and an access network device.
Background
With the continuous evolution of networks, diversified industry application demands have exploded greatly. Network requirements for industry users have become an important deployment requirement for 5G. The fifth generation mobile communication technology (5th-generation, 5G) network provides multiple slicing modes, which can satisfy the demands of both customers (2C) and enterprises (2B). However, the 5G device (5G base station) uses 192-element multi-element antenna devices, and the frequency band used by the 5G device is 3.5GHz, and the coverage range is significantly smaller than that of the device in the frequency band of 2GHz or less, which results in the multiplied number of stations (number of base stations) in a unit area, and thus, the high base station cost and the dense number of stations result in the exponential increase of the network construction cost. Therefore, operators are seeking a solution for co-establishing a base station by multiple operators and performing network deployment by using the co-established base station. The co-building of the base station means that one base station can meet the requirements of multiple operators, and the equipment of the multiple operators is not centralized in the same base station for deployment.
How to meet the access complaints of 2B (which can be understood as private network) users and 2C (which can be understood as public network) users of different operators as much as possible under the condition that resources of the shared base station after co-construction are limited becomes a problem to be solved urgently.
Disclosure of Invention
Embodiments of the present invention provide a user access method and an access network device, 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).
In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:
in a first aspect, a user access method is provided, which is 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 single carrier, and the method includes: acquiring the reserved flow of each service borne by the access network equipment in the current unit time; when determining that the first service exists in all services carried by the access network equipment, calculating that the service priority is less than or equal to the sum of the reserved flows of all second services 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 a preset flow in unit time; and when the sum of the reserved flow rates of all the second services is determined to be less than the second preset unit flow rate 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 acquiring reserved traffic of all services carried by the access network device in the current unit time (that is, traffic that needs to be used in the current unit time), the access network device first determines whether there is a first preset percentage that a reservation of a first service is greater than a preset unit traffic of the first service, and if there is a description that the reservation of the first service is greater than the preset unit traffic, it needs to determine in time whether a new user terminal corresponding to the first service can be allowed to access the access network device. Then, because the public network service and the private network service exist in all services carried by the access network, and the difference of the priorities of the two services requires that the access of the user terminal corresponding to the service with the highest priority be guaranteed as much as possible, when the existence of the first service is determined, the sum of the reserved flows of all second services of which the service priority is less than or equal to that of the first service needs to be calculated, and then the size relationship between the sum of the reserved flows of the second services and the second preset unit flows corresponding to all the second services is judged. When the sum of the reserved flow rates of the second services is determined to be smaller than the second preset unit flow rates corresponding to all the second services, the current priority is considered to be smaller than or equal to the flow rate required by all the services of the first services and not exceed the unit flow rate which is defined by the first services, and on the basis that the priority is higher than the requirement of the first services, the flow rate share which is not used by the second services can be distributed to the first services, so that the access network equipment can allow a new user terminal corresponding to the first services to access at the moment. In summary, the technical solution provided in the embodiments of the present application can satisfy, based on the capacity (flow), the access requirements of the user terminals corresponding to different services carried by the shared base station (access network device) co-established by different operators.
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 single 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 borne by the access network equipment in the current unit time; the computing module is used for computing the sum of the reserved flow of all second services of which the service priority is less than or equal to that of the first service when the judging module determines that the first service exists in all services borne 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 a preset flow in unit time; the processing module is further configured to allow a 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 traffic of all the second services is smaller than a second preset unit traffic corresponding to all the second services.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.
For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order.
At present, because the single cost of the 5G base station is high, and because the coverage area of the base station is small, the number of sites to be arranged in a unit area is large, and the cost of completing the deployment of the 5G communication network is high. Therefore, at present, a shared base station is co-established by a plurality of operators, so that the service requirements of the plurality of operators can be borne. However, how to satisfy the access requirements of users corresponding to private network services and users corresponding to public network services of different operators for the co-established shared base station is a problem to be solved urgently.
In view of the above problems, embodiments of the present application provide a user access method, which can meet 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 as shown in fig. 1, and the system may include: the terminal 01, the access network device 02 and at least one core network device 03(03-1, 03-2, 03-3 and 03-4), wherein each core network device 03 corresponds to an operator core network (a private network core network (supporting 2B services) or a public network core network (supporting 2C services)); for example, referring to fig. 1, 03-1 may correspond to a core network of a public network of an operator a, 03-2 may correspond to a core network of a private network of the operator a, 03-3 may correspond to a core network of a public network of an operator B, and 03-4 may correspond to a core network of a private network of the operator B. After the access network device 02 of the terminal 01 is connected with the access network device, the terminal can access the core network of the public network or the core network of the private network of the corresponding operator through different core network devices 03. Of course, only one core network device 03 may actually exist, and the functions of the above-mentioned multiple core network devices may be completed.
It should be noted that, in the present application, one operator core network corresponds to one public network and a plurality of private networks, a public network service (2C service) refers to all services in one public network, and a private network service (2B service) refers to all services in one private network.
Illustratively, referring to fig. 2, the functional modules in the core network device 03 may include a service distribution requirement collecting module 031, a service dependency analyzing module 032, and a critical capacity customizing module 033. The service distribution requirement collecting module 031 may collect network data of a private network service or a public network service of an operator corresponding to the access network device 02 (e.g., a base station) connected thereto. The network data may include: traffic related data of a service corresponding to the network (average capacity/traffic per target unit time (e.g., hour), maximum capacity/traffic per target unit time (e.g., hour)), traffic flow or the number of users, and the like.
The service dependency analysis module 032 may determine, through a certain calculation, whether the service in the actual scene corresponding to the network data mainly depends on the capacity (flow) 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 thereto. Of course, if all the core networks correspond to the same core network device, the service dependency analysis module included therein independently completes the above calculation process.
The critical capacity customizing module 033 is configured to calculate, through cooperation with the critical capacity customizing module 032 in the other core network device corresponding to the access network device 02 connected thereto, a contracted capacity (a first preset unit flow) per unit time 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 thereto. Of course, if all the 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 a unit time of 1 second and a target unit time of 1 hour as an example, the preset unit flow rate of the public network service can be calculated by the following formula:
wherein, TPU YIs the first preset unit flow, T, of the public network servicePU MaxIs the maximum hourly flow, T, of the public network trafficPU meanThe average hourly flow of the public network traffic.
The preset unit flow of the private network service can be calculated by the following formula:
wherein, TPr YIs the first preset unit flow, T, of the private network servicePr MaxFor the maximum hourly flow, T, of the private network trafficPr meanThe average hourly flow of the public network traffic.
Illustratively, referring to fig. 2, the access network device 02 includes a traffic real-time monitoring module 021, a traffic distinguishing module 022, and a network load balancing module 023. The traffic real-time monitoring module 021 can collect the reserved traffic of private network service and public network service of each operator according to the time granularity of unit time (1 second). The traffic determination module 022 may determine whether to deny or allow the subsequent network load balancing module 023 to the access request of the user terminal of each service according to the traffic of each service and the reserved traffic corresponding to each service collected by the traffic real-time monitoring module 021.
Illustratively, taking a 5G communication network as an example, referring to fig. 3, a practical 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 through a common public radio interface (cpri (ecrpi)), and the public network core network (5GC1) of the operator a, the public network core network (5GC2) of the operator B, the private network core network (5GC3) of the operator 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 NG interfaces.
The 5G baseband processing unit includes a Control Plane (CP) and a User Plane (UP). The control plane has an identification module (specifically, the identification module can be judged by a PLMN (public land mobile network), an APN (access point name), a DNN (Data network name), and the like) for the private network core network and the public network core network of different operators, so that the public network core network and the private network core network of different operators can be distinguished. The traffic real-time monitoring module 021, the traffic discrimination module 022, and the network load balancing module 023 may also all be disposed in the CP.
The 5G radio frequency unit comprises an antenna unit, a switch and a transceiver. The transceiver includes a Digital Up Conversion (DUC), a digital to analog converter (DAC), a transmission antenna (TX), a reception antenna (RX), an analog to digital converter (ADC), and a Digital Down Conversion (DDC).
Specifically, in the technical scheme provided by the present invention, the access network device 02 only carries the public network service and the private network service of all operators through one path of carrier. The channel of carrier includes an uplink carrier and a downlink carrier, a communication link corresponding to the uplink carrier is composed of the antenna unit, the switch, the RX, the ADC, the DDC, and the 5G baseband processing unit in fig. 3, and a communication link corresponding to the downlink carrier is composed of the antenna unit, the switch, the TX, the DAC, the DUC, and the 5G baseband processing unit in fig. 3. When the user terminals corresponding to the operator a and the operator B initiate private network service or public network service, the user terminals transmit the relevant data through the communication link corresponding to the uplink carrier and the communication link corresponding to the blind carrier.
In this embodiment, the access network device 02 may be an access network device (BTS) in a global system for mobile communication (GSM), a Code Division Multiple Access (CDMA), an access network device (Node B, NB) in a Wideband Code Division Multiple Access (WCDMA), an access network device (evolved Node B, eNB) in a Long Term Evolution (Long Term Evolution, LTE), an access network device (eNB) in an internet of things (IoT) or a narrowband internet of things (IoT-NB-PLMN), an access network device in a future 5G mobile communication network or a future evolved Public Land Mobile Network (PLMN), which is not limited in this respect.
For example, the terminal 01 in the embodiment of the present application may be named differently, such as a User Equipment (UE), an access terminal, a terminal unit, a terminal station, a mobile station, a remote terminal, a mobile device, a wireless communication device, a vehicle user equipment, a terminal agent, or a terminal device. The terminal may specifically be a mobile phone, a tablet computer, a desktop, a laptop, a handheld computer, a notebook, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) Virtual Reality (VR) device, and other devices that can communicate with a base station, and the specific form of the terminal is not particularly limited in the embodiment of the present application.
Based on the contents shown in fig. 1 to fig. 3, an 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-:
401. and acquiring the reserved flow of each service carried by the access network equipment in the current unit time.
Illustratively, to ensure that access requests of the user terminal are processed based on capacity in time, the unit time may be one second. Of course, the unit time may be smaller as the technology actually allows, and is not limited specifically here.
For example, in practice, step 401 may be executed by the aforementioned real-time flow monitoring module, and the record after data collection is as follows:
TABLE 1
Wherein YY represents the year, MM represents the month, DD represents the day of the MM month, HH: SS stands for time minute second.
Optionally, as shown in 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 the performance of the co-established shared base station is not affected at all, 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:
and S1, acquiring the average flow of each target unit time of each service loaded by the access network equipment in busy hour in a preset time period before the current unit time.
For example, the target unit time may be 1 hour; in order to save the computing resources and ensure that the collected data can reflect the traffic usage of each service carried by the access network device, the preset time period may be two consecutive weeks of tuesday (any working day) and sunday (any resting day). The busy hour can be determined by the traffic using condition of the corresponding user of the operator, for example, the busy hour can be 9:00-11:00 and 14:00-17:00 in working days, and the non-working day can be 10:00-17: 00.
Illustratively, the step S1 is mainly performed by the service distribution requirement collecting module 031 in the core network device 03 shown in fig. 2.
And S2, determining the large flow target unit time according to the average flow of each target unit time of all services belonging to busy hours in a preset time period.
Illustratively, when the sum of average flows of all the services in a target unit time in busy hours in a preset time period is greater than a third preset ratio of the average flows in the target unit time in busy hours, the target unit time is determined to be a large flow target unit time.
And S3, judging whether the ratio of the number of the large-flow target unit time to the total target unit time corresponding to busy hours in a preset time period is larger than a second preset percentage.
When the ratio of the number of the large-flow target unit time to the total target unit time corresponding to all busy hours is larger than a second preset percentage, executing S4; when the ratio of the number of the large flow target unit times to the total target unit times corresponding to all busy hours is not greater than the second preset percentage, S1 is performed.
Illustratively, the second predetermined percentage may be 30%, or any other feasible value, and is not limited herein.
And S4, sending a corresponding instruction to the access network equipment 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 traffic used by each service in the time of the large flow target unit time is more, it can be considered as very traffic dependent, and if the ratio of the large flow target unit time to the total target unit time in busy exceeds a certain ratio, it indicates that each service carried by the access network device is more traffic dependent, and a corresponding instruction needs to be sent to the access network device to enable the access network device to execute the technical scheme provided by the embodiment of the present application.
For example, the steps S2-S4 are performed by the service dependency analysis module 032 in the core network device 03 shown in fig. 2.
It should be noted that, in practice, the core network device may not execute the step S3, and after the step S2, it is determined whether to execute the step S1 or send a corresponding command to the core network device to execute the step 401 according to the ratio of the number of the large flow target unit time to the total target unit time number corresponding to the busy hour in the preset time period. In addition, the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is equal to a second preset percentage, which can be attributed to a case that the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is greater than the second preset percentage, or can be attributed to a case that the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is less than the second preset percentage, and the case that the ratio of the number of the large flow target unit time to the total target unit time number corresponding to all busy hours is less than the second preset percentage in the example corresponding to fig. 5 is taken as an example, but the present application does not specifically limit this.
402. And judging whether the 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 calculated by the key capacity customization module in the above embodiment.
Illustratively, since the base station needs to be given a portion of emergency bearer capacity, the first predetermined percentage may be 95% (for example only, and may be any other feasible value).
When determining that the first service exists, executing 403; when it is determined that the first traffic is not present, 404 is performed.
It should be noted that, in practice, the step 402 may not exist, after the step 401, when it is determined that the first service exists in all services carried by the access network device, 403 is executed, and when it is determined that the first service does not exist in all services carried by the access network device, 404 is executed.
403. And calculating that the service priority is less than or equal to the sum of the reserved flows of all the second services of the first service.
Illustratively, when the first service is a private network service, the second service is a service other than the first service among 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 the public network services carried 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, TA nowIs the sum of the actual flows of the second traffic,
for the reserved traffic of the kth public network service (N) of all public network services carried by the access network device,
for the reserved flow of the mth private network service in all the private network services carried by the access network equipment,
a reserved flow 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, TPU nowIs the sum of the subscribed flows for the second service,
for the reserved flow of the kth public network service in all the public network services (N) carried by the access network equipment,
a reserved flow for a first service; n is a positive integer, and k is a positive integer.
404. And allowing the user terminals corresponding to all services carried by the access network equipment to access the access network equipment in the current unit time.
Here, the normal access refers to a case where a current 5QI (5G QoS Identifier) (used to identify QoS (Quality of Service)) is maintained, and a new ue corresponding to each Service is allowed to access.
For example, in practice, there is a situation where a certain user terminal needs more traffic in the current unit time than in the previous unit time, and in this case, the new user terminal may refer to a specific service corresponding to the newly added traffic; in practice, there is a case that the user terminal corresponding to the public network service or the private network service in the previous unit time is no longer accessed to the network 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 the new user terminal, and the number of the user terminals remaining after the selection is the same as the number of the user terminals in the previous unit time. Of course, there may be any other possible situations (for example, if the priorities of the user terminals belonging to the same service (public network service or private network service) are different, a new user terminal needs to be selected from a part of user terminals with a lower priority according to the priority), and the new user terminal is specifically selected according to the specific situation.
405. And judging whether the sum of the reserved flow rates of all the second services is greater than a second preset unit flow rate 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 the 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 bearable by the access network equipment in unit time minus the reserved flow of the first service.
When the sum of the reserved flow rates of all the second services is determined to be larger than the second preset unit flow rate corresponding to all the second services, 406 is executed; when it is determined that the sum of the reserved traffic of all the second services is not greater than the second preset unit traffic corresponding to all the second services, 407 is performed.
When the first service is a private network service, the service priority of the private network service itself is higher, and the service use of the private network user needs to be guaranteed preferentially, so as long as the base station itself can carry, the use of the private network service needs to be satisfied continuously, that is, a new user terminal corresponding to the private network service is allowed to access (step 407); the new ue corresponding to the private network service is not allowed to access only when 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 ensuring the use of the private network service, so for the public network service (the reserved flow is greater than the first preset percentage of the first preset unit flow), the user terminal corresponding to the public network service can be allowed to access only if the flow (the sum of the reserved flows) occupied by other public network services is not greater than the sum of the flow agreed by the public network service (step 407), and when the flow occupied by other public network services is greater than the sum of the flow agreed by the public network services (the sum of the first preset unit flow), the access of a new user terminal corresponding to the public network service is forbidden (step 406).
It should be noted that the step 405 may not be actually present, and after the step 403, it is only necessary to determine whether to execute the step 406 or 407 according to the magnitude relationship between the sum of the reserved traffic volumes of all the second services and the second preset unit traffic volume corresponding to all the second services. In addition, the sum of the reserved traffic of all the second services is equal to the second preset unit traffic corresponding to all the second services, which may be attributed to a case that the sum of the reserved traffic of all the second services is greater than the second preset unit traffic corresponding to all the second services, or attributed to a case that the sum of the reserved traffic of all the second services is less than the second preset unit traffic corresponding to all the second services, and the case that the sum of the reserved traffic of all the second services is less than the second preset unit traffic corresponding to all the second services in the example corresponding to fig. 4 is taken as an example, but the present application does not specifically limit this.
406. And forbidding a new user terminal corresponding to the first service to access the access network equipment in the current unit time.
Illustratively, the prohibition here may be that the access network device rejects the service request of the user terminal; but any other feasible way.
When it is determined that the sum of the reserved traffic of the second service is greater than the second preset unit traffic corresponding to all the second services, it may be considered that the traffic required by all the services having the current priority level that is less than or equal to the first service exceeds the predefined unit traffic, and on the basis of ensuring that the priority level is greater than the requirement of the first service, the access network device may no longer allow a new user terminal corresponding to the first service (i.e., a user terminal to which the first service is newly added in the current unit time relative to the previous unit time) to access.
407. And allowing the new user terminal corresponding to the first service to access the access network equipment in the current unit time.
For example, the allowing here may be that the access network device allows the service request of the user terminal and establishes the response connection and issues the response configuration; but 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 further includes, in addition to step 403:
408. and allowing the access of the user terminal corresponding to the services except the first service in all the services carried by the access network equipment in the current unit time.
In the technical scheme provided by the embodiment of the present application, after acquiring reserved traffic of all services carried by an access network device in a current unit time (i.e. traffic that needs to be used in the current unit time), the access network device first determines whether a first service is reserved by a first preset percentage that is greater than a preset unit traffic of the first service, and if the first service is reserved by the first preset percentage, the traffic of the first service is about to exceed the preset unit traffic, and it needs to determine in time whether a new user terminal corresponding to the first service can be allowed to access the access network device. Then, because the public network service and the private network service exist in all services carried by the access network, and the difference of the priorities of the two services requires that the access of the user terminal corresponding to the service with the highest priority be guaranteed as much as possible, when the existence of the first service is determined, the sum of the reserved flows of all second services of which the service priority is less than or equal to that of the first service needs to be calculated, and then the size relationship between the sum of the reserved flows of the second services and the second preset unit flows corresponding to all the second services is judged. When the sum of the reserved flow rates of the second services is determined to be smaller than the second preset unit flow rates corresponding to all the second services, the current priority is considered to be smaller than or equal to the flow rate required by all the services of the first services and not exceed the unit flow rate which is defined by the first services, and on the basis that the priority is higher than the requirement of the first services, the flow rate share which is not used by the second services can be distributed to the first services, so that the access network equipment can allow a new user terminal corresponding to the first services to access at the moment. In summary, the technical solution provided in the embodiments of the present application can satisfy, based on the capacity (flow), the access requirements of the user terminals corresponding to different services carried by the shared base station (access network device) co-established by different operators.
