Method and system for controlling boundary roaming of mobile terminals

Abstract

The present invention provides a method and system for controlling border roaming of a mobile terminal, sorting out the border area through the location registration messages of all mobile terminals in the border area between the local operator network and its adjacent foreign operator network All local mobile terminals in the area, and through the location registration message sent by the VLR of the foreign operator network to the local operator network, screen out the mobile terminals that are roaming in the border area, and finally pull them back to the local operation In this way, it can effectively control the border roaming of the mobile terminal in the border area that is still covered by the operator's network, and prevent it from roaming into the network because of the strong wireless signal of the neighboring operator's network. Terminals generate additional roaming charges in border areas, reduce communication costs, avoid roaming charge disputes, and improve operator service quality.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a method and system for controlling border roaming of a mobile terminal. Background technique [0002] Mobile communication networks (or wireless communication networks) provide coverage for mobile terminals to communicate with wired / wireless communication networks, usually with multiple mobile communication networks provided and operated by multiple different mobile communication network operators. The process in which a mobile terminal subscribed by one mobile communication network operator communicates on the mobile communication network of another mobile communication network operator is called roaming. A mobile communication network usually divides its coverage area into a number of small geographic areas. In mobile communication networks compliant with the GSM protocol, these areas are called location areas. When a mobile terminal travels from on...

Problems solved by technology

In the state of international roaming, mobile terminals such as mobile phones with mobile phone number A must use the roaming service provided by the operator that issued the user identification card of mobile phone number A. Therefore, mobile terminals such as mobile phones with mobile phone number A will check B The local network of the operator in country B reports the basic information of the operator in country B to the operator in China to which the mobile phone number A belongs, and then requests the operator in country B to identify the mobile phone number A according to the agreement between the Chinese operator and the operator in country B And allow the mobile phone number A to communicate under the network of the operator in country B. After going abroad, the mobile terminal where the mobile phone number A is located can access the local mobile communication network abroad for voice or data services, but additional international roaming fees will be incurred.

[0006] However, border roaming charges incurred in some of the above cases where roaming border areas may be unnecessary

Among them, border roaming refers to the border areas between different cities, different provinces, and different countries at the junction of administrative divisions. The signal cross coverage of the base station signal occurs. If the signal strength of two base stations in the border area is different , the user's mobile terminal should still belong to the local operator's network geographically, but it occupies the base station signal in other places because the local signal is weak, and becomes a roaming state, resulting in roaming It brings great inconvenience and dissatisfaction to users, and it is also easy to cause problems such as roaming charges and settlement disputes
