Illegal position updating processing method

Abstract

The method includes following steps: the mobile station originates a location renew request; after network side receives the location renew request, it is decided if the request is the first one; if yes, then makes validity estimation, if it is validity, then makes normal location renew process; if it is invalidity user, then it will be labeled, and the message for confirming false location will be returned to the mobile station; if it is not a first location renew request , then it will be inquired if the user has been labeled as invalidity user; if yes, the message for confirming false location will be returned to mobile station; if not, the normal location renew will be made.

Description

technical field [0001] The invention relates to a method for processing location update in the field of mobile communication, in particular to a method for processing illegal location update. Background technique [0002] In the field of mobile communications, a user's mobile phone must first update its location before accessing the network. For example, when the user's mobile phone moves from one location area (LA) to another location area, it must be registered, that is to say, once the user's mobile phone finds that the location area identifier (LAI) in its memory and the received LAI have changed, In addition, when the user turns on the phone for registration, or within a certain period of time, if there is no contact between the network and the user's mobile phone, the user's mobile phone also needs to get in touch with the network to update the location. [0003] The purpose of location update in the mobile system is to keep the user's mobile phone in touch with the n...

Problems solved by technology

In addition to the above reasons, channel blockage or interference may also cause location update failure, and the user's mobile phone will make a new location update attempt

[0005] Due to various objective reasons, there are some illegal users on the actual network, such as users who have not assigned numbers in the network, users who have been shut down, users without roaming rights, and users with illegal authentication parameters. Sometimes the location update fails due to failure of authentication or other reasons

After the location update fails, the mobile phones of these illegal users will keep trying to update the location, causing the system to repeatedly process these illegal location update requests, causing a great waste of system resources

Especially when these users reach a certain number, it will cause catastrophic consequences to the system. For example, some local communication users frequently go online in other places. Always fail authentication, which will greatly increase the signaling load
