Embodiment
Below in conjunction with the drawings and specific embodiments preferred embodiment of the present invention is described in further detail.
Mobile phone of the present invention adopts based on dual-CPU architecture, the software platform of application subsystem (TE) is selected the foreground MMI subsystem of (SuSE) Linux OS in conjunction with QTopia for use, the software platform of wireless telecommunications subsystem (ME) is selected the whole method for designing that solves of the TTPCOM of ADI platform for use, and the serial ports passage adopts the method for designing that is multiplexed into a plurality of logic channels (MUX) on a physical serial interface.
A kind of IPv6 cell phone software method for designing preferred embodiment provided by the invention based on ppp protocol, the performing step of its method for designing is as follows:
At first, according to mobile phone CPU operation system function difference, operating system is divided into application subsystem and radio communication subsystem, as shown in Figure 1.System divides is finished his corresponding operating of laggard Xingqi: the foreground MMI subsystem of (SuSE) Linux OS in conjunction with QTopia is written in the application subsystem, and the ADI system is written in the radio communication subsystem, AT command software module is written in the application subsystem.
Application subsystem is as the master control system of mobile phone, be responsible for finishing and the user between mutual, if the user need carry out the operation of wireless telecommunications aspect or SIM card aspect, then export corresponding command information in the wireless telecommunications subsystem by application subsystem, control wireless telecommunications subsystem is finished correlation function (the wireless telecommunications subsystem is finished the function of GSM/GPRS wireless telecommunications, can regard a wireless modem as).
Come mutual transferring command information by the AT order between application subsystem and the wireless telecommunications subsystem.Be provided with a module of being responsible for AT order transmitting-receiving specially in application subsystem one side, after the AT order that this module reception user sends, (MUX) sends to the wireless telecommunications subsystem by logic channel, then, application subsystem receives the AT command response that sends from the wireless telecommunications subsystem and sends to corresponding user by logic channel (MUX).
Then, between application subsystem, wireless telecommunications subsystem, GPRS protocol stack (GPRS PS), set up ppp link; By ppp protocol (Point to Point Protocol, point-to-point protocol; This agreement is divided into LCP LCP, authentication protocol AUTH and Network Control Protocol NCP three phases; Wherein, LCP agreement and AUTH agreement and network layer protocol version independent, and be the portable terminal of IPv6 for network layer protocol NCP, the option that NCP consults is the compression protocol of 64 bit identifiers in the IP address.) between application subsystem, radio communication subsystem, GPRS protocol stack, set up ppp link, subsequently application subsystem is connected on the Internet network, thus the function of surfing the Net of realization mobile phone.
That wherein, consults that accompanying drawing 2 can recognize ppp link sets up flow process stage partition process:
Ppp link establishing stage: will select to basic communication modes, both link ends equipment sends configuration information message (Configure Packets) by LCP to the other side, in case a configuration successful packets of information (Configure-Ack packet) is sent out and is received, just finish exchange, entered the LCP opening.
The user rs authentication stage: in this stage, cell-phone customer terminal can send to the identity of oneself access server of far-end.This stage uses a kind of safety verification mode to avoid the third party to steal data or pretends to be the remote handset client to take over and being connected of cell-phone customer terminal.Before authentication is finished, forbid advancing to network layer protocol phase from authentication phase.If authentification failure, the authenticator should transit to the link termination phase.
In this stage, have only LCP LCP, authentication protocol AUTH and link-quality to monitor that the Packets of agreement is allowed to, and other the Packets that receives in this stage must be dropped.
The network layer protocol negotiation phase: after finishing the user rs authentication stage, PPP will be invoked at selected diverse network control protocol (NCP) of link establishment stage.Selected NCP solves the upper-layer protocol problem on the ppp link, for example, can distribute dynamic address to the dial-in customer in this Phase I P control protocol (IPCP).
Like this, through the work of preceding three phases, a complete ppp link has just been set up.
After ppp link is set up and is finished, mobile phone by the GPRS terminal attached to the Internet network terminal after, from PDP (the Packet Data Protocol that activates, packet data protocol) the context stateless obtains 64 bit identifiers in the IP address of IPv6 automatically, and sends application subsystem by the NCP agreement in the ppp protocol to from the wireless telecommunications subsystem; And 64 global address prefix, then by sending to router to network, and the IP packet of receiving router broadcast, send the application subsystem receiving network data to or send data from the wireless telecommunications subsystem by the ppp protocol relaying again, as shown in Figure 3 to network.
Wherein, application subsystem divides two stages to be connected on the Internet network by the wireless telecommunications subsystem:
First stage GPRS network connects, and claims that again GPRS adheres to
Mobile phone sends to the Internet network and adheres to message, SGSN (Serving GPRS Support Node, the GPRS serving GPRS support node) from HLR (Home Location Register, the user attaching location register) collects user data, the user is carried out authentication, adhere to the Internet terminal then;
Second Phase I P network connects, and claims PDP to move scene again and activates
After the GPRS terminal was attached to the Internet terminal, mobile phone obtained the IP address from the PDP Context that activates, receiving network data or send data to network.
In addition, after ppp link foundation was finished, the effect of ppp protocol module was exactly a relaying IP layer data bag between application subsystem and wireless telecommunications subsystem, is transparent for bottom.When link was cancelled, a side PPP initiated the LCP link and stops request, and the opposing party confirms get final product, need not cancel at each NCP initiation link, thereby can reduce the logical complexity of agreement.
Yet, for the present invention, can also adopt other technical design method, such as, the mobile phone application subsystem can adopt operating systems such as Windows Mobile, Symbian, Palm; The wireless telecommunications subsystem can adopt the solution method for designing of platforms such as TI, spreadtrum, MTK, PHILIPS, SKYWORKS.
In a word, the present invention is not limited to above-mentioned execution mode, anyly is familiar with this operator, without departing from the spirit and scope of the present invention, all should drop within protection scope of the present invention.
