Problems solved by technology

However, in the existing process, the home base station as a candidate target base station will not and cannot judge whether the terminal user is a member of its CSG, that is, it cannot decide whether to allow the terminal to access according to the CSG information, let alone notify the terminal, so It will cause the terminal to select the home base station that cannot be accessed when performing the handover during the handover execution phase, thus resulting in a decrease in the handover success rate, an increase in the network burden, and a prolonged handover process

Embodiment 1

[0115] Figure 4 It is a flow chart of Embodiment 1 of the method for switching a terminal to a home base station in the present invention, as shown in Figure 4 As shown, in the handover preparation stage, the home base station as a candidate target base station, after receiving the handover preparation request, the home base station obtains the user identification number (SIS) corresponding to the real user identification of the terminal user from the anchor authenticator of the terminal. ), and then use the SIS and the corresponding CSG information to perform switching control on the terminal; specifically, the following steps are included:

[0116] Step 401: The terminal has connected to the mobile communication network and is ready to perform a handover operation; in the handover preparation stage, the terminal initiates a move request to the serving base station currently serving it, and the request carries a group of candidate target base stations that the terminal cons...

Embodiment 2

[0146] Figure 5 It is a flow chart of Embodiment 2 of the method for switching a terminal to a home base station in the present invention, as shown in Figure 5 As shown, before the serving base station sends a ready handover request message to the candidate target base station in the handover preparation stage, it first obtains the subscriber identity code (SIS) corresponding to the real user identity of the terminal user from the anchor authenticator of the terminal; then the serving base station The SIS is sent to the corresponding candidate target base station; finally, the home base station as the candidate target base station uses the SIS and the corresponding CSG information to control the handover of the terminal. Specifically include the following steps:

[0147] Step 501: same as step 401.

[0148] Step 502: The serving base station sends a context information request message to the anchor authenticator of the terminal, requesting context information related to th...

Embodiment 3

[0161] In the above-mentioned methods of Embodiment 1 and Embodiment 2, the entire process of preparing for handover is triggered by the terminal sending a mobile request to the serving base station. In fact, the serving base station itself can also initiate this process. This scenario can be called The handover initiated by the network is not substantially different from Embodiments 1 and 2. Image 6 It is a flow chart of Embodiment 3 of the method for switching a terminal to a home base station in the present invention, as shown in Image 6 As shown, it specifically includes the following steps:

[0162] Step 601: The terminal has already connected to the serving base station, and the serving base station decides to perform a switching operation according to the communication status of the terminal, for example, according to the load condition of the current serving base station, decides to switch the terminal currently receiving its service to a base station with a smaller ...

Abstract

The invention discloses a method for switching a terminal to a home base station. In the method, when the terminal is determined to be switched to a target home base station, the target home base station performs switching control according to an acquired real user identifier of a terminal user or a user identifier code SIS corresponding to the real user identifier of the terminal user. The invention simultaneously discloses a management method of a closed user group identifier of the home base station, which comprises the following steps of: after finishing executing an initial networking process of the terminal, authenticating an authorized charging AAA server to receive a message for updating the real user identifier of the terminal user or the SIS of the terminal user; and synchronizing the updated real user identifier of the terminal or the updated SIS of the terminal user to an anchor point authentication device of the terminal. The invention simultaneously discloses a device for implementing the method. The scheme of the invention is simple to implement and is practical.

Description

technical field [0001] The present invention relates to a handover technology of a terminal, in particular to a method and a device for handing over a terminal to a home base station. Background technique [0002] In order to provide users with a higher service rate and reduce the cost of using high-rate services, and at the same time, in order to make up for the lack of coverage of existing distributed cellular wireless communication systems, Femtocells are usually set up in places such as homes and office areas. A femtocell is a small, low-power base station with the advantages of affordability, convenience, and low power output. [0003] figure 1 is a schematic diagram of a communication network structure including a femtocell, such as figure 1 As shown, the femtocell can access the core network through the logical network element of the access gateway. A security gateway may exist between the femtocell and the access gateway. The security gateway can be set up togeth...
