- Message or processing CS domain communication service receiving a broadcast message in response to the first user card, receiving a broadcast message on the first user card and processing; and processing the first user in response to the first user card needing to process the CS domain communication service CS domain communication service on the card.
- the second service processing unit 605 when the second service processing unit 605 receives the broadcast message on the first user card and performs processing, it may specifically receive the broadcast message on the first user card, and identify the multi-card multi-standby mobile terminal according to the information in the broadcast message. Whether the location area changes; and in response to the change of the location area where the multi-card multi-standby mobile terminal is located, the location area update is performed on the first user card.
- the first use can be received.
- the CS domain paging message and the broadcast message on the card and the location area update of the first user card maintain the synchronization state between the first user card and the mobile communication network, thereby preventing the first user card from dropping the network. Effectively guarantee the success rate of subsequent communication service operations.
- the first monitoring unit 602 may be in the first user card.
- the second service processing unit 605 receives the broadcast message on the first user card and performs processing according to the instruction of the scheduling unit 604, or performs location area update on the first user card.
- the multiple user cards inserted by the multi-card multi-standby mobile terminal may specifically include any one of a SIM card, an R-UIM card, a UIM card, and a USIM card.
- the third user card and the first user card may be the same user card, or may be two different user cards.
- the multi-card multi-standby mobile terminal is a GSM system terminal
- the first user card and the second user card may be the same user card.
- FIG. 8 is a schematic structural diagram of an embodiment of a mobile terminal according to the present invention.
- the mobile terminal provided by this embodiment can adopt the single radio frequency single baseband scheme to implement the functions of the multi-card multi-standby mobile terminal in the above embodiments of the present invention. As shown in FIG. 8, it includes a radio frequency chip 1, a baseband processing chip 2, and a plurality of user card slots 3.
- the radio frequency chip 1 is used to implement data and message transmission between the baseband processing chip 2 and the communication network, for example, in the general packet radio service (General Packet Radio Service, hereinafter referred to as GPRS) network and the baseband processing chip 2
- the service processing unit 601 forwards the PS domain data, and forwards the CS domain service message, the CS domain PS domain data, and the like between the GMS network and the second service processing unit 605 of the baseband processing chip 2.
- Multiple user card slots 3 are used to insert multiple users Card.
- the baseband processing chip 2 is configured to process the high real-time service in response to the first user card in the network state, and identify whether the PS domain data being transmitted and received in the PS domain service of the currently processed second user card is used to maintain the PS domain.
- the high-real-time service is higher than the real-time requirement of the PS domain service, and the first user card and the second user card belong to multiple user cards inserted by multiple user card slots 3.
- the baseband processing chip 2 may specifically include the baseband processing chip provided by any one of the embodiments of FIG. 6 to FIG.
- Fig. 8 only shows the structure in which the baseband processing chip 2 employs an embodiment shown in Fig. 7.
- the specific structure of the baseband processing chip of the other embodiment of the present invention is used, and the connection relationship with the radio frequency chip 1 and the plurality of user card slots 3 is similar to that of FIG. 8 and will not be described again.
- the baseband processing chip 2 can identify the PS domain of the currently processed second user card when the first user card in the network state in the plurality of user cards needs to process the high real-time service. In the service, whether the PS domain data being sent or received is the key data for maintaining the quality of the PS domain service. If the PS domain data being sent and received is non-critical data, the PS domain service is suspended and the high real-time service is processed.
- a single-radio single-baseband solution can be used to process high-real-time services on other user cards in a process of performing PS domain services on one of the user cards.
- the high-real-time service has higher real-time requirements than the PS domain service.
- the PS domain service When the PS domain data being sent and received in the PS domain service is not critical data, the PS domain service is suspended and the high real-time service is processed first, thereby effectively avoiding high real-time service failure caused by not processing in time, and improving other users.
- the success rate of the high-real-time service on the card; and, because the PS domain data being sent and received in the PS domain service is not critical data, suspending the processing of the PS domain service does not reduce the service quality of the PS domain service, for example, the PS domain service. Interrupt or data transfer rate drops significantly.
- the components of the multi-card multi-standby mobile terminal and the baseband processing chip of the foregoing embodiments of the present invention are not necessarily required or limited to implement the embodiments of the present invention, for example, multi-card multi-standby mobile
- the terminal can also set the display, keyboard, antenna and other peripherals according to actual needs.
- the constituent units of the baseband processing chip may be distributed among other constituent units in the multi-card multi-standby mobile terminal according to actual requirements.
- a plurality of constituent units may be combined into one unit, or one unit may be used.
- the constituent unit is split into multiple subunit implementations.
- connection relationship between the constituent units of the baseband processing chip, and the constituent units of the baseband processing chip and other constituent units of the terminal only shows an example of the information flow direction relationship based on the present invention, and is not limited to the physical connection relationship, and Nor is it necessarily necessary or limited to implement the embodiments of the present invention.
- the embodiment of the invention avoids the conflict between the PS domain service and the high real-time service between the same user card and different user cards in the multiple user cards inserted by the multi-card multi-standby mobile terminal, and solves the single radio single baseband solution.
- the user card or other user card in the process of performing a PS domain service by a user card, cannot handle the problem of high real-time service, and does not cause the service quality of the PS domain service to be degraded; No need for manual operation by the user to handle PS domain services and high realities Switching between time-based services does not result in the loss of data being sent and received in the PS domain service, which improves user satisfaction.
