Embodiment Construction

[0031] First, the basis of the present invention is explained: the CDMA wireless access system is connected with the local exchange through the V5.2 interface, and the V5.2 interface does not transmit the roaming information of the terminal, so the roaming restriction will only be completed inside the wireless access system. Therefore, it is necessary to develop and add VLR / HLR software or hardware function modules similar to mobile communication systems in the CDMA wireless access system, that is, the VLR / HLR module on the BSC side, and this module completes terminal information management, mobility management, and roaming areas. Judgment and Limitation. In order to distinguish it from the module in the mobile communication system, the present invention uses V5VLR (V5.2 interface access location register) and V5HLR (V5.2 interface home location register) for short.

[0032] Second step, explain the working principle of the present invention:

[0033] (1) Establish V5VLR / HLR ...

Abstract

The invention relates to a method of limiting mobile terminal roaming in a CDMA wireless access system (1), comprising: using one or more location area codes LAC and cell identification codes CI to set a user roaming rule in a HLR database; in the call control process of a user mobile terminal (11), VLR inquiries the roaming rule to allow or limit the call according to one or more location area codes LAC and cell identification codes CI therein. The method satisfies flexible limit requirements of user roaming zone for telecommunication traders, and the limit is only set in the HLR database without bringing more terminal design and modification cost, users can select diversified terminals conveniently. The invention has good utility and popularized value for telecommunication traders and users.

Description

technical field [0001] The invention relates to mobile terminal roaming, in particular to a method for restricting mobile terminal roaming in a CDMA wireless access system. Background technique [0002] Roaming is an inherent feature of mobile terminals. Due to the characteristics of wireless networks, terminals can work as usual when moving within a certain range. Roaming restrictions, that is, restricting the movement and use of terminals outside the specified geographical or logical range, usually come from two needs. One is the mandatory requirement of fixed network licenses. Roaming is a unique function of mobile networks, and wireless access cannot meet this requirement. Features; the second is the needs of the operator's own network positioning and planning. At this time, the operator requires restrictions on the roaming of the terminal according to different charging strategies and user positioning. [0003] At present, most wireless access systems either cannot eff...
