[0016] However, in this case, image 3 The above-mentioned processing flow cannot meet the needs of users of private base stations, because in the above-mentioned processing, it is only through authentication processing that it is judged whether the user requesting access is a legal subscriber, but it cannot be judged whether the user is It is the user that the equipment owner of the private base station expects to access. Therefore, the access of other legal subscribers cannot be rejected based on the actual needs of the private base station user, that is, the access authority of the user cannot be effectively controlled, so it cannot prevent illegal Intended users use private cells to provide wireless access services

example 1

[0048] Example 1: Allow terminal access

[0049] Specifically, in the case that the radio access network allows the terminal to access, after step S406, the following processing is further included: the radio access network returns an access control success indication message to the core network. And in this instance, after the access control operation, the user is authenticated.

[0050] Such as Figure 5 As shown, it specifically includes the following processing:

[0051] 501: The terminal sends a wireless access request to the wireless access network;

[0052] 502: The base station or controller processes the access request, allocates corresponding wireless resources to the terminal, and establishes a communication connection between the terminal and the wireless access network;

[0053] 503: The terminal requests the core network to establish a service, which carries a user ID, that is, a core network user ID;

[0054] 504: The wireless access network forwards the ser...

[0065] Example 2: Deny terminal access

[0066] The access control operation and the operations before the access control operation in this example are similar to steps 501-507 of Example 1, and repeated descriptions of the same parts are omitted in order to unnecessarily obscure the present invention.

[0067] In the case that the wireless access network rejects terminal access, if Image 6 As shown, the access control process is executed during the terminal access service process (corresponding to Figure 4 In step S406), and after rejecting the user access (601), further include the following processing:

[0068] Step 602, the core network notifies the terminal to reject the service request;

[0069] Step 603, the core network commands the radio access network to release the connection; and

[0070] Step 604, the radio access network releases the radio resource allocated to the terminal before establishing the communication connection.

[0071] Wherein, optionally, in s...

Abstract

An access control method for a private base station, comprising: step S402, after establishing a communication connection between a terminal and a wireless access network, the terminal sends a service request message to the core network, and carries the core network user information of the user in the service request message identification; step S404, in response to the service request message, the core network queries the database according to the core network user identification to obtain the wireless access network user identification of the user; step S406, the core network transmits the obtained wireless access network user identification to the wireless access network network access, and the wireless access network implements access control on the terminal according to the user identifier of the wireless access network. By using the present invention, the owner of the private base station can directly control the user's access authority on the wireless access network side, preventing unexpected users from using the wireless access service provided by the private cell; The data records of the private base station are placed in the private base station, which is convenient for the owner of the private base station to maintain the user's access rights in real time.

Description

technical field [0001] The present invention relates to a distributed cellular wireless communication system, and in particular relates to an access control method of a private base station. Background technique [0002] A distributed cellular wireless communication system is composed of terminals, base stations, and a core network (CN) (see figure 1 ), there may also be a base station controller or a distributed network controller between the base station and the core network (see figure 2 ), used to manage the base station and aggregate the connection between the base station and the core network. The network composed of base stations and network controllers is called the radio access network (RAN), which is responsible for access layer affairs, such as the management of radio resources. Each base station or network controller can be connected to one or more core networks. The core network is responsible for non-access stratum affairs, such as mobility management. A t...
