Method for realizing localized roaming of mobile terminal, mobile terminal and roaming server

Abstract

The invention provides a method for realizing localized roaming of a mobile terminal, a mobile terminal and a roaming server. Including: when it is detected that the mobile terminal user is roaming, obtain its own location information and send its own location information, mobile terminal identification, first user identification and corresponding password to the roaming server; receive the second user identification and corresponding authentication sent by the roaming server; Authorization parameters; send a network registration request including the second user identity and corresponding authentication parameters to the roaming network side, so that the roaming network side can confirm that the mobile terminal is pre-registered according to the second user identity and corresponding authentication parameters Accept the registration request directly after authenticating the user; receive the feedback message of successful network registration sent by the roaming network side. The invention can realize the localized roaming service of the mobile terminal and does not need to frequently update SIM card information and additionally provide an available data link to carry out the authentication interaction process between the mobile terminal and the background server during the realization process.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for realizing localized roaming of a mobile terminal, a mobile terminal and a roaming server. Background technique [0002] The mobile communication system provides users with roaming capabilities, and users can communicate in different places and in different cellular network cells. During the roaming process of the existing mobile terminal, the call of the mobile user in the roaming state has to establish a communication link through the mobile network of the home location and the roaming location, so that the mobile terminal user can use various telecommunication services in the roaming state. Since the communication route is longer in the roaming state and more network resources are consumed, the service charge for mobile terminal users using roaming services is much higher than that of local users, especially when using data services, the service charge...

Moreover, this implementation method will also increase the delay of the authentication process. If the current data link is unstable or the delay is relatively large, it may cause authentication failure or timeout
