When second modem 60 receives the downlink network data of operator's transmission of the second LTE network communication, second modem 60 controls port by Ethernet and downlink network data is sent to the second application processor 50, downlink network data are sent to second modem 60 by the second application processor 50, and it is transmitted to the first application processor 10, complete the transmission of downlink network data in second modem 60.

Should be understood that, corresponding with the first radio-frequency module is the operator of the first LTE network communication, corresponding with the second radio-frequency module is the operator of the second LTE network communication, wherein, the operator that the operator of the first LTE network communication communicates with the second LTE network can be identical, it is also possible to different, if the operator of the first LTE network communication is for time mobile, the operator of the second LTE network communication can be mobile, UNICOM or telecommunications, and other situations repeat no more.

When the first modem 20 and second modem 60 are simultaneously received data transfer instruction, the first modem 20 and second modem 60 can use LTE network to carry out data transmission according to data transfer instruction simultaneously.Namely, when the second Subscriber Identity Module 90 connected when the first user identification card 80 that the first modem 20 connects and second modem 60 needs to carry out data service simultaneously, first user identification card 80 and the second Subscriber Identity Module 90 can carry out data service by LTE network by corresponding modem simultaneously. Such as, user is when the operator using the first LTE network communication of first user identification card 80 correspondence of mobile terminal 100 is downloaded movies by LTE network on backstage, still can carry out web page browsing on foreground by LTE network by the carrier network of the second LTE network communication of the second Subscriber Identity Module 90 correspondence, and the two is independent of each other.

When mobile terminal 100 carries out speech business and data service simultaneously, as when first user identification card 80 carries out speech business, the second Subscriber Identity Module 90 carries out data service simultaneously. first user identification card 80 carries out the process of speech business: after calling subscribe clicks dial key from the first application processor 10, and mobile terminal 100 receives the instruction called, and the instruction called is handed down to the first modem 20. first modem 20 is interacted with network by the first radio-frequency module 33, then at network side through a series of process and Signalling exchange, beep-page message corresponding to the instruction called is sent to called subscriber, if beep-page message sends successfully, then erecting a wireless channel between calling subscribe and called subscriber by Signalling exchange, wireless channel is for the transmission of user's communication data. communicating data in the transmitting procedure of calling subscribe place mobile terminal 100 is: communicating data is sent to the first coding/decoding module 50 by microphone by calling subscribe, after the first coding/decoding module 50 processes, communicating data is sent to the first data processing module 70 by the first coding/decoding module 50, communicating data is after the first data processing module 70 processes, communicating data is sent to the first modem 20 by the first data processing module 70, after the first modem 20 processes, communicating data is sent to the first radio-frequency module 33 by the first modem 20 again, by the first radio-frequency module 33, communicating data is sent the operator of the first LTE network communication. communicating data is (in the present embodiment in the transmitting procedure of called subscriber place mobile terminal 100, called subscriber place mobile terminal 100 only one of which modem): radio-frequency module receives the communicating data that carrier network sends, communicating data is sent to modem by radio-frequency module, after modem processes, communicating data is sent to data processing module by modem again, communicating data is after data processing module processes, communicating data is sent to coding/decoding module by data processing module, after coding/decoding module processes, communicating data is sent to loudspeaker by coding/decoding module, after loudspeaker receive communicating data, output communicating data, complete the call between calling subscribe and called subscriber.

Now the second Subscriber Identity Module 90 carries out the process of data service and is: uplink user data: when the first application processor 10 receives user data, after user data is processed, it is sent to the second application processor 50 by ether Controlling model port, and it is pass-through to second modem 60 by the second application processor 50, second modem 60 processes user data, user data after processing is sent to the second radio-frequency module 22, user data is sent to the operator of the second LTE network communication by the second radio-frequency module 22, user data is sent to Internet by the operator of the second LTE network communication,Down user data: user data is sent to the carrier network of the second LTE network communication by Internet, user data is sent to the second radio-frequency module 22 by the carrier network of the second LTE network communication, second radio-frequency module 22 processes user data, and the user data after processing is sent to second modem 60, second modem 60 processes user data, and the user data after processing is sent to the second application processor 50, and send to the first application processor 10 through the ether Controlling model port of the second application processor 50, complete the data service of the second Subscriber Identity Module 90.

The first user identification card 80 of mobile terminal 100 and the second Subscriber Identity Module 90 can carry out data service simultaneously, and first user identification card 80 and the second Subscriber Identity Module 90 do not interfere with each other when carrying out data service simultaneously. When first user identification card 80 and the second Subscriber Identity Module 90 carry out data service simultaneously, the process that first user identification card 8011 carries out data service is consistent with the workflow that above-mentioned second Subscriber Identity Module 90 carries out data service, does not repeat them here. Such as, user, when using mobile terminal 100 to be made a phone call by the CS speech business of the carrier network of first user identification card 80 correspondence, still can be downloaded movies on backstage by the carrier network of the second Subscriber Identity Module 90 correspondence.

Mobile terminal 100 provided by the invention, by being arranged to the too Controlling model port of data interaction and for the mutual modem port of control command, realize being normally carried out the mutual of control command and data between two application processors, the support of the bottom is concurrently provided for realizing business datum; And realize supporting that two Subscriber Identity Modules all reside in LTE network, available two LTE passages carry out the concurrent transmission of data service, improve efficiency of transmission; Additionally, when carrying out data traffic transmission, speech business transmission also can be carried out, improve Consumer's Experience; And only with a set of audio-frequency module and codec, hardware cost can be saved.
