Abstract
The invention provides a method for implementing GSM support in an android system. The method includes the following steps of using a pppd service dialing module to start pppd service dialing; using a monitoring module to monitor whether a ppp0 network interface is activated, and if the ppp0 is not activated within a prescribed time, which indicates that the pppd service dialing fails, then restarting the service dialing; and simulating two pseudo-terminals ps0 and ps1 via a simulation module, wherein one of the terminals is used for AT command transmission and the other for data transmission. The method achieves phone communication and data connectivity functions in a Gsm module having only one physical serial port.
Description
Technical field
The present invention relates to Mobile portable terminal, relate in particular to the Mobile portable terminal that uses Android (android) system.
Background technology
The development of 3G technology and maturation, be widely used 3G module, and become gradually the standard configuration of consumer electronics product.Android system is as a operation system of smart phone, is taking the chip of high pass as foundational development, because high pass chip has been realized ppp dialing with hardware, and in current Android Android system, do not possess again the support to ppp dialing.Due to little in the transmission of the industry such as the tax, logistics data volume, use 3G function not only to make cost uprise, and cause the waste of bandwidth resources, use so GSM service module can significantly reduce costs, and can meet project demands.Meanwhile, at present, GSM service module, with its cheap price and stable performance, is still widely used on some industry special equipments.
That 3G module or 2G module all will provide two passages: AT instruction path and data transmission channel.3G module is all generally that USB mouth receives and send data.USB kernel-driven can simulate at least two serial ports, and access issues has just solved like this, does not have the competition of resource.GSM service module only has a physical serial interface, so just cannot meet when sending AT instruction simultaneously and transmit data, must realize two same physical serial interface of channel time-sharing multiplexing.
Summary of the invention
This invention is the support by realize ppp dialing in Android Android system, thereby realizes gsm communication.
The present invention proposes a kind of method that GSM supports that realizes on Android system, it comprises the following steps:
Use pppd service dial module to start pppd service dialing;
Use monitoring modular to be used for monitoring ppp0 network interface and whether activate, if ppp0 is not activated in official hour, not success of pppd service dialing is described, restart described service dialing;
Simulate two pseudo-terminal ps0 and ps1 by analog module, one of them terminal is for AT command, and another is for transfer of data.
Wherein, the data packing of sending from pseudo-terminal, become GSM0710 protocol format packet, send to modulation /demodulation module by serial ports; Resolve on the other hand the packet being received by described modulation /demodulation module, be distributed to each pseudo-terminal.
The invention allows for a kind of device that GSM supports of realizing on Android system, it comprises:
Pppd service dial module is used for starting pppd dialing;
Whether monitoring modular is used for monitoring ppp0 network interface and activates, if ppp0 is not activated in official hour, not success of pppd service dialing is described, restarts service dialing;
Analog module is used for simulating two pseudo-terminal ps0 and ps1.
Wherein, a described terminal ps0 is for AT command, and another terminal ps1, for transfer of data, becomes GSM0710 protocol format packet from pseudo-terminal the data of sending packing, send to modulation /demodulation module by serial ports; Resolve on the other hand the packet being received by described modulation /demodulation module, be distributed to each pseudo-terminal.
Brief description of the drawings
Fig. 1 is the method flow diagram of on Android system realizing GSM support consistent with the embodiment of the present invention;
Fig. 2 is consistent with the embodiment of the present invention schematic diagram of realizing the device that GSM supports on Android system.
Specific embodiment
Fig. 1 is the method that on Android system realizes GSM support consistent with the embodiment of the present invention, and it comprises the following steps:
Step 1, use pppd service dial module start pppd service dialing, and above-mentioned pppd service is a kind of monitor service based on point-to-point protocol.
Whether step 2, use monitoring modular are used for monitoring ppp0 network interface and activate, if ppp0 is not activated in official hour, not success of pppd service dialing are described, restart and serve dialing.
Step 3, simulate two pseudo-terminal ps0 and ps1 by analog module, one of them terminal is for AT command, and another is for transfer of data.AT instruction is generally applied to being connected and communicating by letter between terminal equipment and PC application.AT command set is from terminal equipment (Terminal Equipment, or data terminal equipment (Data Terminal Equipment TE), DTE) to terminal adapter (Terminal Adapter, TA) or data circuit termination equipment (Data Circuit Terminal Equipment, DCE) send.
So, the data packing of sending from pseudo-terminal, become GSM0710 protocol format packet, send to modulation /demodulation module by serial ports; Resolve on the other hand the packet being received by modulation /demodulation module, be distributed to each pseudo-terminal.
Fig. 2 is the device (1) of on Android system realizing GSM support consistent with the embodiment of the present invention, and it comprises with lower device:
In system, build pppd service dial module, monitoring modular.Wherein, pppd service dial module is used for starting pppd dialing; Whether monitoring modular is used for monitoring ppp0 network interface and activates.If ppp0 is not activated in official hour, not success of pppd service dialing is described, restart service dialing.After service dial-up success starts, transfer to GSM service module to carry out, by analog module wherein, simulate two pseudo-terminal ps0 and ps1, one of them terminal is for AT command, another becomes GSM0710 protocol format packet for transfer of data data packing of sending from pseudo-terminal, sends to modulation /demodulation module by serial ports; Resolve on the other hand the packet being received by modulation /demodulation module, be distributed to each pseudo-terminal.
Above execution mode is only for illustrating the present invention; and be not limitation of the present invention; those of ordinary skill in the art; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
