Abstract
The invention discloses a method and a system for realizing a multiplexing peer-to-peer protocol (PPP) data channel to report an attention (AT) command. The method comprises the following steps that: mobile data terminal equipment packs a received AT command report message to form a PPP data packet during PPP data transmission together with mobile data user equipment and transmits the data packet to an opposite end through the PPP data channel between the data packet and the mobile data user equipment; and the mobile data user equipment decodes the PPP data packet, extracts the AT command report message from the data packet and correspondingly processes the message. By reporting the AT command through the multiplexing PPP data channel, the mobile data terminal equipment receives incoming calls/short messages while dialing up through the PPP data channel; and the method has the obvious advantage of low cost, is easy to realize and does not increase equipment volume.
Description
Technical field
The present invention relates to the mobile data communication field, relate in particular to implementation method and system that a kind of multiplexing PPP information passage reports the AT order.
Background technology
Along with mobile communication technology especially EVDO, the develop rapidly of high speed mobile communication technologies such as HSPA, moving data terminal equipments such as card of surfing Internet, U cat become the favor that is subjected to the consumer more and more, become the communication commodity.Yet, these moving data terminal equipments exist a common defective: setting up in the process that the PPP information passage dials up on the telephone with the mobile data subscriber equipment, owing to being taken by the PPP information passage, port do not have unnecessary port to use, so can't receive incoming call/note, bring inconvenience to the user so undoubtedly.
At this defective, two kinds of solutions are arranged usually, a kind of port of on moving data terminal equipment, setting up exactly, be the PPP information passage port different with the AT call allocation, but will certainly cause the increase of production cost of moving data terminal equipment and the increase of volume like this, this does not just satisfy day by day miniaturization, the thing U.S. valency more honest and cleaner market demand of active user at communication apparatus.
Another kind of scheme is exactly to solve above-mentioned defective by the serial port agreement that 3GPP standard agreement GSM07.10 stipulates.The serial port agreement of GSM07.10 regulation be the 3GPP tissue in order to support the tunnel agreement of multi-business flow, accept incoming call or transmitting-receiving note when can be used for supporting dialling up on the telephone by the PPP information passage.Yet, because this serial port agreement is used for reference communications protocol model, to stipulate detailedly, the modular requirement height causes the realization workload of agreement big, thereby the disposal ability of the processor of moving data terminal equipment is had high requirement.
Thereby a kind of new being easy to of needs proposition realizes, low cost solution.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that realizes that multiplexing PPP information passage reports AT to order, and corresponding system, realizes that moving data terminal equipment can receive incoming call/note when dialling up on the telephone.
For solving the problems of the technologies described above, the present invention adopts following solution: a kind of method that realizes that multiplexing PPP information passage reports AT to order comprises:
Carrying out in the process of PPP information transmission with the mobile data subscriber equipment, moving data terminal equipment is packaged into the PPP information bag with received AT command report message, and with its by and the mobile data subscriber equipment between the PPP information passage be sent to the opposite end, the mobile data subscriber equipment carries out respective handling to the decoding of described PPP information bag and after extracting wherein AT command report message.
Said method also comprises: when described moving data terminal equipment is packaged into the PPP information bag with received AT command report message, to the AT order flag bit set of wherein reserving.
Described mobile data subscriber equipment is only decoded to the PPP information bag that carries AT order sign and is therefrom extracted AT command report message.
In the said method, described AT command report message is positioned over the information field of PPP information bag; Described AT order flag bit is arranged at the address field of PPP information bag.
A kind of system that realizes that multiplexing PPP information passage reports AT to order, comprise moving data terminal equipment and mobile data subscriber equipment, and described moving data terminal equipment and mobile data subscriber equipment include AT command response/report processing module, PPP information line module, PPP information protocol module, described moving data terminal equipment and mobile data subscriber equipment and also comprise AT order Multiplexing module;
At the moving data terminal equipment end, described AT order Multiplexing module is used in AT command response/when reporting processing module to receive AT command report message, this AT command report message is packaged into the PPP information protocol module by local terminal is sent to the opposite end behind the PPP information bag;
At mobile data subscriber equipment end, described AT order Multiplexing module is used for therefrom extracting AT command report message after the received PPP information bag decoding that carries AT command report message of the PPP information protocol module of local terminal, and sends it to the AT command response of local terminal/report processing module to carry out respective handling.
In the said system, at the moving data terminal equipment end, described AT order Multiplexing module also is used for when received AT command report message is packaged into the PPP information bag, to the AT order flag bit set of wherein reserving.
The present invention has following beneficial effect:
The present invention reports AT order by multiplexing PPP information passage, has realized accepting incoming call/note when moving data terminal equipment dials up on the telephone by the PPP information passage, and has had low cost, is easy to realize, do not increase the remarkable advantage of equipment volume.
Description of drawings
