Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a method for realizing localized roaming of a mobile terminal, the mobile terminal and a roaming server.
Background
The mobile communication system provides roaming capability for users, and the users can realize communication in different places and different cellular network cells. In the roaming process of the existing mobile terminal, the call of the mobile user in the roaming state is to establish a communication link through the mobile network of the home location and the roaming location, so that the mobile terminal user uses various telecommunication services in the roaming state. Because the communication route is longer in the roaming state and the consumed network resources are more, the service charge of the mobile terminal user using the roaming service is much higher than that of the local user, and particularly when using the data service, the service charge is more expensive. It is clear that this is in conflict with the increasing data service usage demands of current mobile terminal users.
In order to reduce the high service charge of the mobile terminal user when using the roaming service, some mobile terminal manufacturers have adopted a method of cooperating with the home network operator so as to dynamically adjust the user identity according to the roaming position of the mobile terminal user to obtain the home user service, thereby avoiding the problem of high service charge caused by using the roaming service. Specifically, the following two methods are mainly used for implementing the dynamic adjustment of the user identity according to the roaming location of the mobile terminal user in the prior art:
soft SIM card technology
The soft SIM card technology is to write a soft SIM card in the mobile terminal, so that the SIM card information in the mobile terminal can be dynamically updated according to the roaming location of the mobile terminal user.
(II) cloud SIM card technology
The cloud SIM card technology is realized through a background server, specifically, when a mobile terminal requests for registration to an operator network, the mobile terminal sends an authentication request issued by the operator network to the background server, and the background server calculates an authentication result and sends the calculated authentication result to the operator network through the mobile terminal.
In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:
in a region with more operators, the soft SIM card technology is implemented, and the problem of frequently updating SIM card information occurs at the mobile terminal side, thereby causing a large overhead and affecting the continuity of services.
For the implementation of the cloud SIM card technology, when the mobile terminal and the background server perform the authentication request and the authentication result interaction, it is necessary to rely on an available data link, that is, another available data link is needed to perform the authentication request and the authentication result interaction between the mobile terminal and the background server in the initial registration process of the local card. If no WIFI network is available currently, the functions cannot be realized by the single-card mobile terminal, and the double-card mobile terminal also needs to ensure double-card double-pass. Moreover, this implementation method will also increase the time delay of the authentication process, which may result in authentication failure or timeout if the current data link is unstable or the time delay is relatively large.

the second receiving module is configured to receive a feedback message that the network registration is successful, where the feedback message is sent by the roaming destination network side.
9. The mobile terminal of claim 8, further comprising a detection module, wherein the detection module is configured to detect whether the mobile terminal user roams.
10. The mobile terminal of claim 8, wherein the first subscriber identity is a subscriber identity provided by the mobile terminal provider in advance, and the second subscriber identity is a home subscriber identity allocated on the roaming-site network side.
11. The mobile terminal of claim 8, further comprising a closing module configured to close a physical SIM card of the mobile terminal to answer the incoming call transfer on the physical SIM card through the second subscriber identity.
12. The mobile terminal according to claim 8, wherein the mobile terminal further comprises a shutdown module, and the shutdown module is configured to shut down the data service of the physical SIM card of the mobile terminal, so as to perform the data service through the second subscriber identity.
13. A roaming server is characterized in that the roaming server comprises a confirmation module, a first receiving module, a second receiving module, a first sending module and a second sending module;
the first receiving module is used for receiving the position information of the mobile terminal, the mobile terminal identification, the first user identity identification and the corresponding password which are sent by the mobile terminal;
the confirmation module is used for confirming whether the mobile terminal is a legal user or not according to the mobile terminal identification of the mobile terminal, the first user identity identification and the password;
the first sending module is used for sending a request for acquiring a second user identity and corresponding authentication parameters to a roaming area network side to which the position of the mobile terminal belongs when the confirmation module confirms that the mobile terminal is a legal user;
the second receiving module is configured to receive the second subscriber identity and the corresponding authentication parameter allocated by the roaming destination network side;
the second sending module is configured to send the second user identity and the corresponding authentication parameter to the mobile terminal, so that the mobile terminal sends a network registration request to the roaming destination network side for network registration according to the second user identity and the corresponding authentication parameter.
14. The roaming server of claim 13, wherein the first subscriber identity is a subscriber identity provided by the mobile terminal provider in advance, and the second subscriber identity is a home subscriber identity allocated on the roaming-destination network side.
