In the embodiment of the present invention, utilize when authentication request is initiated to the communication network (also referred to as second communication network) of random zone to the second virtual user identification module card data that the first modem module in user terminal loads, inventor finds that second communication network possesses the tenability (transfer of data is carried out in the communication link support between second communication network and user terminal) of carrying out transfer of data to user terminal in enforcement process of the present invention, therefore for second communication network, user terminal can initiate to utilize existing communication link in user terminal (to be called the first communication link when authentication request is registered to second communication network first, set up based on loaded subscriber identify module card data by the second modem module in user terminal) the second virtual user identification module card data are sent to server, authentication is carried out in conjunction with KI and the second virtual user identification module card data of receiving and second communication network mutual by server, when authentication success, by the first modem module to the first communication link being established to second communication network based on the second virtual user identification module card data be loaded on the first modem module, follow-up preferential use second communication link, authentication request is sent to second communication network via server, authentication mutual (concrete authentication interaction flow follows the specification that second communication Virtual network operator is formulated) is carried out based on the KI safeguarded in conjunction with the second virtual user identification module card data and second communication network by server, without the need to again utilizing the first communication link set up via second modem module, such second modem module can load the entity user identification module card (as the SIM card 1 in Fig. 2 or the data in SIM card 2) of user, like this can either with the rate usage data transport service of random zone this locality at random zone, can support that again user uses privately owned entity user identification module card to carry out speech business and short message service.
Based on the scheme of above-mentioned user terminal and data traffic transmission, the following embodiment of the present invention is proposed.
Embodiment one
The present embodiment records a kind of data business transmission method, can be applied to above-mentioned user terminal, and as shown in Figure 3, composition graphs 4, comprises the following steps:
In step 101, when user terminal is in random zone, the subscriber identify module card data that the Modem2 (second modem module) arranged in the subscriber identify module card data that load of Modem1 (the first modem module) in adjustment user terminal and user terminal loads; The result of adjustment is loaded with first user identification module card data in Modem2, and first user identification module card data can make Modem2 be supported in the data traffic transmission of random zone, following several situation is existed for first user identification module card data:
1) first user identification module card data are the subscriber identify module card data in the entity user identification module card (being such as in SIM card 1 in Fig. 4 and SIM card 2) of user, and the roaming of the user contracting data supported data business that this entity user identification module card is corresponding, that is, Modem2 can be established to the communication link (the first communication link) of the communication network (the first communication network) of random zone based on these first user identification module card data;
2) first user identification module card data are virtual user identification module card data, and described first user identification module card data include KI (KI), in this case, first user identification module card data can be inserted in Modem2 in advance, and be loaded on Modem2 where necessary, authentication request is sent based on the virtual user identification module card data loaded to the first communication network to make Modem2, to register at the first communication network, be established to the communication link (the first communication link) of the first communication network.
In step 102, be established to the first communication link of the first communication network based on the first user identification module card data be loaded in second modem module after adjustment process.
As described in step 101, first communication network is the communication network of random zone, the transmission of the first communication link in order to make user terminal carry out data service at random zone based on Modem2, it is to be noted, no matter first user identification module card data are the data in the entity user identification module card of user, or first user identification module card itself is the virtual user identification module card data be set in advance in Modem2, first user Module recognition module card data are only can make user terminal at different random zones based on Modem2 transmitting data service, but be difficult to ensure that user terminal can use the rate of random zone this locality to carry out the transmission of data service.
In step 103, the first communication link is utilized to obtain the second virtual user identification module card data from server.
Second virtual user identification module card data refer to the virtual user identification module card data obtained from server, are only and aforesaid first user identification module card data separation, not refer in particular to some virtual user identification module card data of server maintenance; In practical application, server can safeguard the set of the virtual user identification module card data corresponding from multiple different region, thus can when user terminal roams to corresponding region to the different virtual subscriber identify module card data in multiple user terminal authorizes user terminal current roaming region.
Exemplarily, server support maintenance shown in Fig. 4 belongs to the virtual user identification module card data of the communication network of random zone, as a rule, complete subscriber identify module card data comprise authentication information (also namely for the information at network registry), as the international mobile station equipment identity (IMSI be made up of MCC and MNC, InternationalMobileSubscriberIdentificationNumber), integrated circuit card identification code (ICCID, IntegrateCircuitCardIdentity), cryptographic algorithm (for authentication) and KI (KI, KeyIdentifier), in order to ensure the access security of communication network, when server is to user terminal mandate virtual user identification module card data, can retain at KI in this locality, when user terminal needs access communications network, the virtual user identification module card data of correspondence can be sent to server, be that user terminal completes the authentication interaction flow of network registration (this flow process follows the specification of the formulation of communication network operator by server, difference depending on operator may be distinguished to some extent), and by authentication successful information informing user terminal, to make user terminal access communications network, be established to the communication link of communication network.
In step 104, by the second virtual user identification module card Data import to the first modem module.
In step 105, the first communication link is utilized to initiate the authentication request first to the second virtual user identification module card data to second communication network, authentication by time be established to the second communication link communication network of random zone (use) of second communication network, second communication link is for carrying the data service of user terminal at random zone, and second communication network is the communication network belonging to random zone.
As previously mentioned, because KI can be retained in this locality by the server shown in Fig. 4, if the Modem1 of user terminal needs based on the second virtual user identification module card data access second communication network, the second virtual user identification module card data based on loading just are needed to send authentication request to server, it is mutual that the KI stored based on this locality by server and the second virtual user identification module card data and second communication network carry out authentication, informing user terminal (the Modem2 in informing user terminal when authentication success, by Modem2, authentication successful information is notified Modem1), to make the Modem1 in user terminal when knowing authentication success based on the second virtual user identification module card data access second communication network, thus set up the second communication link of user terminal and second communication network, after user terminal sets up the second communication link with second communication network, second communication link transmission data business can be used, this makes it possible to use the rate of random zone this locality at random zone transmitting data service, save rate.
In step 106, utilize the subsequent authentication request of second communication chain road direction second communication network initiation to the second virtual user identification module card data.
After the above-mentioned authentication first success of the user terminal that second communication network is right, follow-uply may have second communication network side or subscriber terminal side initiates authentication (concrete initiator depends on the networking authentication specification of operator) again;
When needing the legitimacy again verifying the second virtual user identification module card data, because the tenability of second communication link to data traffic transmission is not lost, therefore can continue to utilize second communication link, send authentication request via second communication network to the server shown in Fig. 4, ensure that Modem1 is based on the access state of the second virtual user identification module card data at second communication network, thus the rate of random zone this locality can be used to carry out the transmission of data service;
Because follow-up authentication request can send based on second communication link, Modem2 does not need the first user identification module card data of the data traffic transmission continuing to be carried in random zone, thus the first user identification module card data that Modem2 loads can be unloaded, and on Modem2, load the data in the privately owned entity user identification module card of user; As shown in Figure 5, exemplarily, can by the subscriber identify module card Data import in the SIM card 2 in Fig. 5 to Modem2, user terminal provides circuit domain business as speech business or short message service based on entity SIM card 2 couples of users of user.
Embodiment two
