Abstract

The invention provides a communication method applied to a mobile phone. When a handset using a 2G network receives a signal for processing a CS (or PS) service in the course of processing the CS (or PS) service, a modem in the handset checks whether the 2G network supports DTM. If the 2G network supports DTM, the modem sets the flag of the wireless communication interface layer to 1 to inform an application program in the mobile phone that the mobile phone supports DTM. The application program sends a DTM request to the mobile phone network through the wireless communication interface layer and the modem, and the modem receives the DTM distribution command replied by the mobile phone network and forwards the DTM distribution command to the application program. And then, the mobile phone executes the application program according to the DTM distribution command and simultaneously processes the PS service and the CS service.

Description

Communication method applied in mobile phone

technical field

The invention relates to a communication method, in particular to a communication method applied in a mobile phone.

Background technique

General Packet Radio Service (GPRS) mobile phones mainly include three types: A, B, and C. Category A: Data switching (Packet Switch, PS) mode and circuit switching (Circuit Switch, CS) mode can exist at the same time. The PS mode refers to the data service of the GPRS standard, and the CS mode refers to the voice service of the Global system for Mobile communications (GSM) standard. For example, when a class A mobile phone calls a class A mobile phone with an ordinary mobile phone during data transmission, the class A mobile phone should be able to answer the call and talk, and continue to maintain data transmission during the call. Category B: can be used for data business and voice business, but both cannot work at the same time. When the class B mobile phone is in the data transmission period, ordinary mobile phones can also dial the class B mobile phone, and the class B mobile phone will have a corresponding prompt. After answering, it will switch to the voice service, while the data service will be suspended. You can switch back to the data service. Category C: Similar to category B. But the switching between the data service and the voice service is manual. At present, most mobile phones use the second generation (Second Generation, 2G) network, such as Class B mobile phones of the GPRS standard.

The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings.

Detailed ways

Referring to FIG. 1 , it is an application environment diagram of a preferred embodiment of the communication method applied in a mobile phone according to the present invention. This method is applied to the mobile phone 10 . The mobile phone 10 includes an application program 11, a radio interface layer (Radio Interface Layer) 12 and a modem 13. The wireless communication interface layer 12 is responsible for data transmission between the application program 11 and the modem 13 . The application program 11 includes a call application program (Call Tracker), a short message application program (SMS Tracker), a service application program (Service Tracker) and a data application program (Data Tracker).

The modem 13 receives the broadcast information of the mobile phone network 20, and judges whether the mobile phone network 20 is a second generation (Second Generation, 2G) network or a third generation (Third Generation, 3G) network and whether the mobile phone network 20 supports a two-way transmission mode according to the broadcast information (Dual Transfer Mode, DTM), and whether to support data exchange (PacketSwitch, PS) mode and circuit switching (Circuit Switch, CS) mode at the same time. According to judgment result modem 13 sets corresponding sign for wireless communication interface layer 12, for example if this mobile phone network 20 is 2G network and does not support DTM, then modem 13 sets the sign of wireless communication interface layer 12 as " 0 ", if this mobile phone network 20 is a 2G network and supports DTM, then the modem 13 sets the flag of the wireless communication interface layer 12 to "1". In other embodiments, the logo of the wireless communication interface layer 12 may also be set to other numbers or characters.

The application program 11 judges whether the mobile phone 10 supports DTM according to the sign of the wireless communication interface layer 12 . If it is determined that the mobile phone 10 supports DTM, the application program 11 sends a DTM request to the modem 13 through the wireless communication interface layer 12 . The modem 13 forwards the DTM request to the mobile network 20 , requests the mobile network 20 to activate the DTM, receives the DTM allocation command replied by the mobile network 20 and forwards it to the application program 11 . The application program 11 executes services in the PS mode and CS mode according to the DTM distribution command, for example, using the mobile phone 10 to browse webpages during a call. The DTM allocation command includes the time slots (Timeslot) allocated by the mobile phone network 20 to the CS service and the PS service.

DTM provides services in the form of channels, and a channel is a group of time slots with one sender and several receivers. In DTM, CS service and PS service can work at the same time, but work together. That is to say, the two know each other and coordinate to receive control information. The mobile 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 on the same frequency point and the time slots must be adjacent, and the CS service can use the time slot of the PS service (that is, in a time slot Half-rate CS service and PS service can be realized on the slot), and the time slot adjacent to the CS service can also be used.

Referring to FIG. 2 , it is a flowchart of a preferred embodiment of the communication method applied in the mobile phone according to the present invention.

In step S201, the mobile phone 10 runs the corresponding application program 11 to process CS service or PS service. For example, the mobile phone 10 runs a call application to perform a call service, that is, makes a call or receives 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 the website.

In step S202, the mobile phone 10 receives a trigger signal for processing PS services or CS services. For example, the user of the mobile phone 10 may want to query data online during a call, or the mobile phone 10 receives an incoming call during the process of downloading data from a website.

Step S203, the modem 13 receives the broadcast information of the mobile phone network 20, and judges whether the mobile phone network 20 is a 2G network or a 3G network according to the broadcast information. At present, 2G networks include GPRS, GSM and other networks, and 3G networks include Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) and other networks. If the mobile phone network 20 is a 3G network, the mobile phone using the 3G network can process the CS service and the PS service at the same time, so the process ends. If the mobile phone network 20 is a 2G network, the process goes to step S204.

In step S204, the modem 13 judges whether the 2G network supports DTM according to the broadcast information. If the 2G network supports DTM, the process goes to step S206. If the 2G network does not support DTM, the process enters step S205, and the modem 13 sets the flag of the wireless communication interface layer 12 to "0". Afterwards, flow process enters step S212, and mobile phone 10 needs to process the application program 11 of PS service or CS service, such as data application program or call application program, knows that mobile phone network 20 does not support DTM according to the mark " 0 " of wireless communication interface layer 12, The modem 13 is requested to suspend the CS service or PS service being processed so as to process the PS service or CS service that needs to be processed.

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

Step S207, the mobile phone 10 needs to process the application program 11 corresponding to the PS service or the CS service, such as a data application program or a call application program. According to the sign "1" of the wireless communication interface layer 12, it is known that the mobile phone network 20 supports DTM, and sends to the modem 13 DTM request.

Step S208, the modem 13 forwards the DTM request to the mobile network 20, and requests the mobile network 20 to activate the DTM.

In step S209, the modem 13 receives the DTM allocation command replied by the mobile phone network 20 and forwards it to the corresponding application program 11 of the PS service or CS service. The DTM allocation command includes the time slots (Timeslot) allocated by the mobile phone network 20 to the CS service and the PS.

In step S210, the modem 13 replies to the mobile network 20 that the DTM assignment command has been received.

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

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation.
