Embodiment Construction

[0020] The essence of the implementation method of mobile phone localized roaming provided by the present invention is that the home network of the mobile phone of the user automatically assigns a local roaming area to the mobile phone user when the area is a roaming area according to the roaming area of ​​the mobile phone of the user. Mobile phone number, which is notified to the user. When the user leaves the contracted roaming area, take back the temporary number used by the user. In the contracted roaming area, the user can use the local number to make a call or answer the call, and can enjoy the localized roaming service. Taking the country as the roaming area as an example, the user does not need to pay the international long-distance fee to answer the call in the contracted roaming country, which greatly reduces The communication fee when the user roams is reduced.

[0021] The present invention will be further described below by taking inter-country roaming as an exam...

Abstract

The invention provides a method for realizing localized roaming of a mobile phone. Firstly, the mobile phone at home obtains the mobile number of the contracted roaming area. HLR requests the RNM at the home location to assign a roaming mobile phone number to the user's mobile phone, and the HLR inserts the above number and other data into the VLR where the user is currently located, and notifies the user of the above number, and updates the location of the user's mobile phone in the HLR In this way, when an incoming or outgoing call occurs on the user's mobile phone, the feedback from the roaming number manager in the user's home area is used to process the call; the above-mentioned solution can enable roaming users to enjoy localized roaming services, reducing the number of mobile users in roaming. The communication fee in the state.

Description

technical field [0001] The invention relates to a method for realizing mobile phone roaming. Background technique [0002] In the existing implementation method of mobile phone roaming, the call of the mobile user in the roaming state must establish a communication link through the mobile network of the home location and the roaming location, and the mobile phone user can use various telecommunication services in the roaming state. Such as initiating a call, answering an incoming call, etc. However, since the communication route in the roaming state is longer and consumes more network resources, the cost of the roaming service is higher than that in the non-roaming state. Especially when the user is in the state of international roaming, any call received is an international long-distance call, that is, the call must be completed through the communication link established by the mobile network of the home country and the roaming country, and the roaming user must pay from t...
