Fig. 1 is the schematic flow sheet that the present invention roams processing method embodiment mono-, and the executive agent of the present embodiment is mobile terminal, and the mobile terminal that the present embodiment provides can be by software and/or hardware are realized arbitrarily.As shown in Figure 1, the roaming processing method that the present embodiment provides, comprising:

Step 101, mobile terminal receive the first virtual subcard that vcard server sends by packet-switched domain or the Internet in roaming place, wherein, the first virtual subcard is that vcard server is according to the spendable virtual subcard of the definite mobile terminal of the positional information of mobile terminal, the first service operator that the service provider of the first virtual subcard is described roaming place;

In mobile terminal, be provided with virtual main card, virtual main card can set in advance in mobile terminal in the time that mobile terminal dispatches from the factory, and also can be arranged in mobile terminal by alternate manner, for example, by the customization of service provider, is stored in mobile terminal.Virtual main card has ownership place service provider, supports roaming, and in the time that mobile terminal is positioned at the roaming place of virtual main card, this virtual main card is roaming state in roaming place.User is in unpaid situation, and virtual main card can connect roaming place service provider, completes the registration to virtual main card, and after virtual main card succeeds in registration, virtual main card is supported communication in the mode of roaming, and carries out charging by roaming place service provider.Virtual main card and virtual subcard in the present embodiment are virtual card, for hard card, there is no concrete physical carrier, are stored in mobile terminal with software form.Virtual subcard can be supported roaming, also can not support roaming, and virtual subcard can use in the roaming place of described virtual main card, and while use in described roaming place, rate are lower than the rate of the virtual main card arranging in the hard card of installing in mobile terminal or mobile terminal.Preferably, virtual subcard can be non-roaming state in described roaming place.

Step 102, mobile terminal send the registration request for the first virtual subnet card is registered to first service operator, so that first service operator registers the first virtual subnet card;

The first virtual subcard that step 103, mobile terminal receive the transmission of first service operator authenticates the certification of passing through by information, and mobile terminal sticks into Serial Communication in roaming place by the first virtual subnet.

The application scenarios of the present embodiment be mobile terminal in roaming state, comprise National roaming and international roaming.The rate that it will be understood by those skilled in the art that international roaming are higher, and therefore, the present embodiment is more suitable for mobile terminal in international roaming state.For the concrete residing roaming state of mobile terminal, the present embodiment is not particularly limited herein.

Service provider in the present embodiment, as communication when main body, to the certification that networks of virtual main card or virtual subnet card, or carry out and send or when reception is moved, concrete executive agent is carrier network devices, and this carrier network devices can be the various servers in carrier network.

Vcard server in the present embodiment, independent setting, can the virtual subcard list of maintenance and management, communicates by letter, for issuing virtual subcard to each mobile terminal with each network by mobile terminal; Can also carry out network service with each service provider, carry out authentication for the virtual subnet card that each service provider is served.

In specific implementation process, in step 101, mobile terminal receives the first virtual subcard that vcard server sends by packet-switched domain or the Internet.Wherein, the first virtual subcard is that vcard server is according to the spendable virtual subcard of the definite mobile terminal of the positional information of mobile terminal.

Because packet-switched domain can provide Packet data service at a high speed, use IP communication, can make mobile terminal Internet access; And mobile terminal is by the internet communication of WLAN or wireline interface realization, all makes mobile terminal communicate by letter easily and fast with vcard server.Mobile terminal can directly be received the first virtual subcard that vcard server sends, and directly uses.

Alternatively, the positional information that vcard server is obtained mobile terminal comprises following possible implementation.

A possible implementation, mobile terminal obtains the positional information of mobile terminal by navigation system; Mobile terminal sends the positional information of mobile terminal to vcard server by the Internet.

Particularly, can obtain WLAN (wireless local area network) (Wireless LAN at mobile terminal, be called for short WLAN) WIFI when service of providing, mobile terminal can pass through global positioning system (Global Positioning System, be called for short GPS) etc. navigation system obtain the positional information of mobile terminal, and send the positional information of mobile terminal to vcard server by the Internet.

Another kind of possible implementation, mobile terminal is determined the second service operator of the first virtual main card in roaming place, send the registration request for the first virtual main card is registered to described second service operator, so that described second service operator registers the first virtual main card, and send the positional information of mobile terminal to vcard server, preset the first virtual main card in mobile terminal, the first virtual main card support roaming, the first virtual main card is roaming state in roaming place.

After mobile terminal is determined second service operator, send the registration request for the first virtual main card is registered to second service operator, second service operator registers the first virtual main card, comprise circuit switching (the Circuit SwitchedDomain to the first virtual main card, be called for short CS) registration in territory and packet switching (Packet Switch is called for short PS) territory.

After second service operator succeeds in registration to the first virtual main card, in the time that the residing lane place of mobile terminal changes, the mobile communications network of second service operator can upgrade attaching position register (home location register, be called for short HLR) or VLR Visitor Location Register (Visitor Location Register, be called for short VLR) in Location Area Identification (the Location Area Identity of this mobile terminal that preserves, LAI), certificate server corresponding to second service operator can obtain the current LAI of mobile terminal from HLR or VRL, thereby obtain the positional information of mobile terminal.It will be understood by those skilled in the art that second service operator can also obtain by alternate manner the positional information of mobile terminal, the present embodiment repeats no more herein.

The implementation that another is possible, mobile terminal is determined the second service operator of the first virtual main card in roaming place, the public land mobile network that mobile terminal is corresponding according to second service operator is determined the positional information of mobile terminal; Mobile terminal sends the positional information of mobile terminal to vcard server by packet-switched domain or the Internet.

It will be appreciated by those skilled in the art that, in the time that mobile terminal can be communicated by letter with vcard server by the Internet, mobile terminal can not initiated to the registration request of second service operator, and mobile terminal sends the positional information of mobile terminal to vcard server by the Internet.

In the time that mobile terminal can not be communicated by letter with vcard server by the Internet, after mobile terminal is determined the second service operator of the first virtual main card in roaming place, mobile terminal is initiated the registration request to second service operator, after succeeding in registration, mobile terminal can send by packet-switched domain the positional information of mobile terminal to vcard server.

In two kinds of above-mentioned implementations, in mobile terminal, be provided with the first virtual main card of supporting roaming, when mobile terminal is started shooting in roaming place or gets back to signal coverage from blind area, mobile terminal all needs to search net, determines the second service operator of the first virtual main card.

Particularly, mobile terminal is first in the roaming place definite second service of start operator.
