Referring to FIG. 1, the present invention is applied to a preferred embodiment of a communication method in a mobile phone. Application environment diagram. This method is applied to the mobile phone 10. The mobile phone 10 includes an application 11, a radio interface layer 12, and a data machine 13. The wireless communication interface layer 12 is responsible for the transfer of data between the application 11 and the data machine 13. The application 11 includes a Call Tracker, a SMS Tracker, a Service Tracker, and a Data Tracker.

The data machine 13 receives the broadcast information of the mobile phone network 20, and determines whether the mobile phone network 20 is a second generation (Second Generation, 2G) network or a third generation (Third Generation, 3G) network and the mobile phone network according to the broadcast information. 20 Whether to support Dual Transfer Mode (DTM), and whether to support both the Packet Switch (PS) mode and the Circuit Switch (CS) mode. According to the determination result, the data machine 13 sets a corresponding flag for the wireless communication interface layer 12. For example, if the mobile phone network 20 is a 2G network and does not support the DTM, the data machine 13 sets the flag of the wireless communication interface layer 12 to “0”. If the mobile phone network 20 is a 2G network and supports DTM, the data set 13 sets the flag of the wireless communication interface layer 12 to "1".

The application 11 determines whether the mobile phone 10 supports the DTM based on the flag of the wireless communication interface layer 12. If it is determined that the mobile phone 10 supports the DTM, the application 11 transmits a DTM request to the data machine 13 via the wireless communication interface layer 12. The data machine 13 forwards the DTM request to the mobile phone network 20, requests the mobile phone network 20 to enable the DTM, receives the DTM allocation command replied by the mobile network 20, and forwards it to the application 11. The application 11 executes the services in the PS mode and the CS mode according to the DTM allocation command, for example, browsing the webpage using the mobile phone 10 during the call. The DTM allocation command includes a time slot (Timeslot) allocated by the cellular network 20 to the CS service and the PS service.

The DTM provides services in a channel manner, and a channel is a set of time slots with one sender and several receivers. In the DTM, the CS service and the PS service can work simultaneously, but work together. That is to say, the two know each other and coordinate the acceptance of control information. The mobile phone network 20 can only allocate one time slot to the CS service. The time slots allocated by the CS service and the PS service must be at the same frequency point and the time slots must be adjacent. The CS service can use the time slot of the PS service (ie, in one The half-rate CS service and the PS service are implemented on the time slot, and the time slot adjacent to the CS service may also be used.

Referring to Figure 2, there is shown a flow chart of a preferred embodiment of the communication method of the present invention applied to a mobile phone.

In step S201, the mobile phone 10 runs the corresponding application 11 to process the CS service or the PS service. For example, the mobile phone 10 runs a call application to perform a call service, that is, makes a call or accepts an incoming call, or the mobile phone 10 runs a data application to perform a data service, such as logging in to a website and downloading data from a website.

If the 2G network does not support the DTM, the flow proceeds to step S205, and the data machine 13 sets the flag of the wireless communication interface layer 12 to "0". Then, the process proceeds to step S212, and the mobile phone 10 needs to process the PS service or the CS service application 11, such as a data application or a call application. According to the flag "0" of the wireless communication interface layer 12, the mobile phone network 20 does not support the DTM. The request data machine 13 suspends the processing of the CS service or the PS service to process the PS service or the CS service that needs to be processed.

In step S206, the data machine 13 sets the flag of the wireless communication interface layer 12 to "1".

In step S207, the mobile phone 10 needs to process an application 11 corresponding to the PS service or the CS service, such as a data application or a call application. According to the identifier “1” of the wireless communication interface layer 12, the mobile phone network 20 supports the DTM to the data machine. 13 Send a DTM request.

In step S208, the data machine 13 forwards the DTM request to the mobile phone network 20, and requests the mobile phone network 20 to enable the DTM.

In step S209, the data machine 13 receives the DTM allocation command replied by the mobile phone network 20 and forwards it to the application 11 corresponding to the PS service or the CS service. The DTM allocation command includes a time slot (Timeslot) allocated by the cellular network 20 to the CS service and the PS.

In step S210, the data machine 13 replies to the mobile phone network 20 that the DTM allocation command has been received.

In step S211, the mobile phone 10 simultaneously processes the PS service and the CS service according to the DTM allocation command. For example, the corresponding application 11 such as the data application and the call application are executed according to the time slot allocated by the mobile phone network 20 to the CS service and the PS.
