Embodiment

Below in conjunction with drawings and the specific embodiments, the present invention is further detailed explanation.

Mobile communication equipment in the embodiment of the present invention can be various mobile terminal, such as mobile phone, flat computer and notebook, can also be portable, pocket, hand-hold type, built-in computer or vehicle-mounted mobile device.Mobile communication equipment can perform wireless access network switched voice under various communication network and/or data.Typically, this communication network can be global mobile communication (GSM, GlobalSystemforMobileCommunication) network, code division multiple access (CDMA, CodeDivisionMultipleAccess) network, Wideband Code Division Multiple Access (WCDMA) (WCDMA, WidebandCodeDivisionMultipleAccess) network, Long Term Evolution (LTE, LongTermEvolution) communication network etc.Dissimilar communication network may be runed described in different operators.The type of communication network does not form the restriction to the embodiment of the present application.

Fig. 1 is the application scenarios schematic diagram of the data service method of the embodiment of the present invention.In FIG, be that mobile phone is described for mobile communication equipment.Typically, the user of mobile phone is positioned at permanent residence, but may transfer to described roaming place due to the reason such as need of work, travelling from described permanent residence.

In permanent residence, user may have two subscriber identify module cards, such as the first SIM card and the second SIM card.Here SIM card is only example, and described subscriber identify module card can also be subscriber identification module (UIM, UserIdentityModule) card.The type of described subscriber identify module card can change according to the type of communication network.Mobile phone can be communicated with the first communication network NM1 by the first SIM card, also can be communicated with second communication network N M2 by the second SIM card.The communication network corresponding with each subscriber identify module card is referred to according to each communication network in the embodiment of the present application.Correspondingly, the first communication network NM1 is usually different from second communication network N M2 and communicates.Such as, the first SIM card can belong to the GSM network of the mobile operator operation of China, and the second SIM card can belong to the WCDMA network of CHINAUNICOM's operation of China.Certainly, described two SIM cards also can be two telephone numbers under same communication network, and now described first communication network NM1 and second communication network N M2 is such as GSM network.

Cellphone subscriber leaves permanent residence and arrives roaming place and be in roaming state.For international roaming, cellphone subscriber uses the network of operator overseas under international roaming state, international roaming expenses standard be based on the operator of two countries between agreement determine, the data service rate of the international roaming in most countries or area are higher than domestic data service rate.In order to save rate, terminal use may need the subscriber identify module card buying roaming place, and the operator business hall to the communication network of roaming place is gone to handle relevant business, and buys the phonecard of roaming place, and operation is inconvenience comparatively.

In the embodiment of the application, described mobile communication terminal comprises the first modulation /demodulation module and the second modulation /demodulation module, thus mobile communication terminal can side by side use two subscriber identify module cards to perform data traffic transmission.After mobile communication terminal arrives roaming place, can be retained and the data traffic transmission under the communication network in a subscriber identify module card of permanent residence by a communication port, another communication port is set to sky, i.e. the described not corresponding insertion SIM card of another communication port.Load the subscriber identify module card corresponded under second communication network of roaming place in mobile communication terminals, and the subscriber identify module card of roaming place is registered to the second communication network N M2 of roaming place.Like this, mobile communication terminal can utilize the subscriber identify module card under second communication network N M2 to perform data traffic transmission by another communication port, thus saves roaming data traffic rate.Like this, the user of mobile communication equipment is after arrival roaming place, do not need the entity obtaining subscriber identify module card, only need to obtain its card information, thus mobile communication equipment can use the second communication network N M2 of roaming place to carry out data traffic transmission easily.
