Method for realizing roaming limitation

Abstract

The invention discloses a method to realize limiting cruise by setting admitted cruise zone list for terminal, which also comprises: A. terminal sends wireless business request with one or more enabled subzone information to mobile exchange center of local network; B. the exchange center decides whether the carried subzone information belongs to said list, if yes, executes the wireless business; or else, rejects the business. This method needs not to modify IMIS or MIN of terminal one by one when subzone information varies, and realizes cruise limit when terminal is on overlap zone of two subzones.

Description

technical field [0001] The invention relates to a technology for realizing terminal roaming in a wireless local network, in particular to a method for realizing roaming restriction in a wireless local network. Background technique [0002] At present, there are many wireless local network operators, which have the right to operate wireless local networks, but cannot operate mobile networks. In places with relatively strict regulations, the roaming area of ​​terminals is required not to exceed the area under the jurisdiction of the wireless local network operator. The range of the base station or the range of multiple base stations, beyond the range, the call service cannot be provided to the terminal. This situation is called roaming restriction of the terminal. [0003] Now, the process of realizing terminal roaming restriction is: dividing the wireless local network into multiple cells, and each cell is identified by a number segment. When the terminal is allowed to roam...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the network optimization, capacity expansion and relocation of the wireless local network, the cell will increase or change. IMSI or MIN, it is cumbersome to modify one by one, not suitable for commercial use;

[0007] 2. For a terminal in the overlapping area covered by two cells, it may not be able to initiate a call or be called. This is because: when one of the two cells is a cell where the terminal is restricted from roaming, and the other is a cell where the terminal is allowed to roam, Due to the change of the wireless environment, it is very likely that the terminal receives the call signal of the terminal restricting roaming cell for a period of time, so it cannot initiate a call or be called
