Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The communication base station sharing method provided by the application can be applied to the application environment shown in fig. 1. Wherein, each terminal (i.e. User Equipment: UE, User Equipment) communicates with each operator core network through a base station. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices; the base station may be a 2G (2-Generation with free telephone technology)/3G (3rd-Generation)/4G (the 4th Generation mobile communication technology)/5G (5th-Generation) system base station. In addition, the telecommunication core network, the mobile core network, the connectivity core network, etc. shown in fig. 1 are only for illustrative purposes and do not limit the kinds of operators; the examples of the present invention are not limited to the following examples, but may be implemented by any means.
The traditional base station deployment mode has the defects; in order to more fully share hardware resources, such as base station resources, and further to reduce purchase cost of an operator base station and subsequent maintenance cost, and solve the problem of complex deployment environment during network deployment, the application provides a method for sharing a mobile communication LTE base station, which can solve the problems of complex deployment environment, inflexibility, high purchase cost of the base station, high subsequent maintenance cost and the like of the existing mobile communication network.
In an embodiment, as shown in fig. 2, a method for sharing a communication base station is provided, and the method is applied to the base station in fig. 1 as an example for description, it should be noted that the present application is applicable to base stations of 2G, 3G, 4G, and 5G systems, and is not necessarily limited to the 4G base station. The 4G standard base station is taken as an example for explanation, and may include the following steps:
step 202, establishing a cell;
wherein, in the step of establishing the cell: confirming that the link is successfully established with each operator core network respectively S1.
Specifically, the base station establishing a cell requires S1 links to core networks of multiple operators. Further, the base station may establish S1 links with core networks of a plurality of different operators simultaneously.
It should be noted that a cell in this application may refer to an area covered by one base station or a part of a base station (sector antenna) in a mobile communication system, and in this area, a mobile station can reliably communicate with the base station through a radio channel. In the present application, the base station first establishes an S1 path with multiple operator core networks, and then establishes a cell to execute step 204, thereby implementing communication with a terminal (i.e. user equipment).
And step 204, when the cell is established, sending the broadcast carrying the identifier of each operator by using the shared carrier.
Specifically, after the cell is established, a shared carrier is used to send a broadcast carrying multiple operator identifiers, and a terminal (i.e., user equipment) receives the broadcast sent by the base station; in one specific example, the operator identification may include a PLMN ID (Public Land Mobile Network ID);
that is, for multiple operators, the present application proposes to use the same carrier and use the carrier to broadcast PLMN IDs of multiple operators simultaneously, so that multiple operators can use the same cell-level feature.
The steps 202 and 204 may be unified into a base station starting procedure as shown in fig. 3; as shown in fig. 3, after the base station is powered on and started, in the process of establishing a cell, it is necessary to establish S1 links with core networks of multiple operators; after the cell is established, the shared carrier is used for sending the broadcast carrying the PLMN IDs of the multiple operators, so that the terminal receives the broadcast sent by the base station.
Step 206, receiving a random access request based on broadcast feedback from the user equipment; wherein, the random access request carries the operator identification; and selecting a corresponding operator core network according to the operator identification carried by the random access request, and sending an indication of successful random access to the user equipment.
Specifically, when the base station receives a random access related signaling message (i.e., a random access request) sent by the UE, the base station may determine the load of each core network with which the link S1 is successfully established, select a suitable core network, and indicate that the random access of the user equipment is successful.
In a specific example, the random access request may be an RRC (Radio Resource Control) connection setup complete message; and the inside of the base station selects a proper core network for the UE according to a load balancing principle, and then the terminal interacts with the base station and the core network, and the terminal is finally successfully accessed to the base station (namely, the random access is successful).
Step 208, receiving a service request initiated by the user equipment; performing data interaction with a corresponding operator core network according to the service request, and obtaining interaction information; and sending the interactive message to the user equipment.
Specifically, the base station receives a service request initiated by user equipment, performs data interaction with a corresponding operator core network according to the service request to obtain interaction information, and sends an interaction message to the user equipment; the base station can judge whether the terminal carries out data service according to the type of the service request, and if so, the base station instructs the terminal to configure a corresponding identifier on a data plane according to the selected core network and carry out data interaction with the core network. That is, based on the present application (taking a 4G network as an example), the 4G core network of the operator shares the same set of LTE base station equipment, so as to provide signaling interaction and data service.
For another example, the base station determines whether the service is a voice service according to the type of the service request, and if so, the base station only shares the LTE network and the 2/3G network does not share the LTE network, so that the voice service needs to be dropped to the respective 2/3G network (i.e., the base station instructs the terminal to perform a voice drop process); namely, taking the 4G network as an example, by applying the present application, the 4G core network of the operator shares the same set of LTE base station equipment for providing signaling interaction and data service, and simultaneously uses the 2/3G networks of the operators for providing voice service. Furthermore, different operators only share the 4G LTE network, but do not share other networks, and when using the voice service, call is made, and the call falls back to the 2/3G network to perform the voice service (i.e., voice fall-back process).
In a specific embodiment, the service request is a dedicated bearer establishment request;
specifically, the base station determines the type of the service according to the dedicated bearer type requested to be established.
In the application, the same base station is connected with the 4G LTE network shared among different operators, which means that compared with the traditional mode, one operator corresponds to one base station, and the cost for purchasing the base station and the subsequent maintenance cost are lower. Meanwhile, the interference on the air interface side is reduced, the interference among different base stations is avoided, and the base stations are deployed simply and quickly. The application can be applied to base stations of 2G, 3G, 4G, 5G and other systems, and is not necessarily limited to 4G.
It should be noted that, in the present application, terminals of different systems may respectively refer to a unicom terminal, a mobile terminal, and a telecommunication terminal in fig. 1. And the terminals of different systems are finally served by the operator matched with the system through the scheme provided by the application.
The network sharing architecture of the present application should allow different operators' core networks to connect to the shared radio access network. Different operators establish connection with the same base station and share the same base station, so that one base station can provide services for terminals of different systems, the purchase cost and the layout cost of the base station are saved, and the maintenance cost of the operators is relatively reduced; the method realizes the method that a plurality of operator core networks share one base station, and has low research and development maintenance cost and great benefit.
How to more efficiently perform base station layout, and meanwhile, the purchase cost and the layout cost of the base station are lower, which is very important in commercial deployment and product operation and maintenance. According to the base station sharing method, the core network of the operator shares the same set of base station equipment, so that various costs are greatly reduced, the layout difficulty of the base station is reduced, the problems can be well solved by using the method, and the base station sharing method has a good market prospect.
In an embodiment, as shown in fig. 4, a method for sharing a communication base station is provided, which is exemplified by the application of the method to a terminal (i.e., user equipment) in fig. 1, and may include the following steps:
step 402, receiving a broadcast carrying an identifier of each operator sent by a base station; the broadcast is sent by the base station by adopting a shared carrier when the cell establishment is finished;
step 404, confirming whether the base station can be accessed according to the broadcast; if yes, feeding back a random access request; the random access request is used for indicating the base station to select a corresponding operator core network according to an operator identifier carried by the random access request;
specifically, the UE determines whether it can access the base station according to the received base station broadcast, and initiates a random access procedure if it supports access at the base station. And meanwhile, the base station selects a corresponding operator core network according to a load balancing principle, carries the data identifier of the corresponding selected operator core network, and transmits a random access request to the selected operator core network, so that the terminal and the base station, and the base station and the core network interact with each other, and the terminal is finally and successfully accessed into the base station.
Step 406, if receiving an indication of successful random access sent by the base station, initiating a service request to the base station;
specifically, the terminal initiates a service request, i.e., a dedicated bearer establishment request flow. The base station can judge the service type according to the service request type and the special bearing type requested to be established.
And step 408, receiving the interactive information sent by the base station, wherein the interactive information is obtained by the base station performing data interaction with the corresponding operator core network according to the service request.
Specifically, the terminal receives the interaction message sent by the base station, and according to the selected core network, may perform configuration on the data plane, and then perform data interaction with the core network.
In a specific embodiment, the operator core network is a core network that successfully establishes an S1 link with the base station in the cell establishment process.
In a particular embodiment, the operator identification comprises a PLMN ID; the random access request is a message for establishing RRC connection; the service request is a dedicated bearer establishment request.
It should be noted that, the specific process performed from the base station side may refer to the aforementioned method for sharing a communication base station performed from the base station perspective, and is not described herein again.
In this application multiple operators use the same cell level feature. Taking the 4G network as an example, different operators in the application only share the 4G LTE network, and other networks do not share the same, and when using the voice service, the operators dial a call and fall back to the respective 2/3G networks to perform the voice service. Specifically, the 4G core network of the operator shares the same set of LTE base station equipment to provide signaling interaction and data service, and uses the 2/3G network of the operator to provide voice service.
As described above, based on the network sharing architecture provided in the present application, it is possible to allow core networks of different operators to connect to a shared radio access network. Different operators establish connection with the same base station and share the same base station, so that one base station can provide services for terminals (namely user equipment) with different systems, the purchase cost and the layout cost of the base station are saved, and the maintenance cost of the operators is relatively reduced.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
