Be the TD network below with the 3G network, the 2G network is that the application example of GSM network further describes.
As shown in Figure 2, should with the hardware module of example part can regard as by three independently system form: application subsystem, TD wireless telecommunications subsystem and gsm wireless communication subsystem, each subsystem all framework on separate processor.
Application subsystem is the master control system of mobile phone terminal, is responsible for finishing mutual with the user, if the user need carry out the operation of wireless telecommunications aspect or SIM card aspect, then controls corresponding wireless telecommunication system by this subsystem responsible and finishes correlation function.This subsystem also is responsible for the Client-initiated business being distinguished, and according to the TD network condition bearer network being adjusted when data service by " the CS business is walked the GSM network, and the PS business is walked the TD network " logic in this example.
TD wireless telecommunications subsystem responsible TD network carries out the operation of wireless telecommunications aspect or UIM card aspect.This subsystem also is responsible for the relevant parameter of monitoring and reporting terminal TD network of living in power in this example.This subsystem is made up of TD Modem module with separate CPU and corresponding UIM card module.
The TD Modem module of this example is different from commercial at present TD Modem, and it does not possess TD/GSM bimodulus handoff functionality, and ' TD ONLY ' pattern is only arranged.It mainly is responsible for based on the data service of TD network and the data interaction of visual telephone service.And the signal strength signal intensity of current terminal TD network of living in monitored, when signal changes, in time notify application subsystem by the form of AT order.
By the UIM card module, TD Modem module can with TD pattern draw-in groove in that carry out alternately with the data on the UIM card of the different IMSI of MSISDN with the GSM pattern.Comprise that the customer identification information that reads on the card and authentication information and TD network side carry out alternately; By the wireless air interface mode business datum on the card is upgraded and managed; Manage etc. being stored in userspersonal informations such as telephone number in the card, short message.
The gsm wireless communication subsystem is responsible for the operation that the GSM network carries out wireless telecommunications aspect or SIM card aspect.Similar with TD wireless telecommunications subsystem, also form by GSM Modem module with separate CPU and corresponding SIM card module.
GSM Modem module mainly be responsible for the carrying of whole terminal all CS circuit domain business except that video telephone, and the data link by 2G is carried data services related temporarily when the TD signal is not good.
By the SIM card module, GSM Modem module can with GSM pattern draw-in groove in that carry out alternately with the data in the SIM card of the different IMSI of MSISDN with the TD pattern.Comprise that the customer identification information that reads on the card and authentication information and TD network side carry out alternately; By the wireless air interface mode business datum on the card is upgraded and managed; Manage etc. being stored in userspersonal informations such as telephone number in the card, short message.
Behind the mobile phone terminal openings of the two cards of dual-network and dual-standby, can be initiatively with two different IMS I numbers with (U) SIM card of MSISDN number, report each self-corresponding TD network and GSM network.
Use telephone service to be example with the user, as user during by dialing interface exhalation voice call, application subsystem is according to the logic of " the CS business is walked the GSM network; the PS business is walked the TD network ", call gsm wireless communication subsystem and GSM network and carry out alternately, and carry out business by the GSM network carrying and the other side.When called, the network equipment is set up link and bearer service according to terminal at the information (mainly being IMSI number that endpoint registration GSM network uses) and the terminal GSM wireless telecommunications subsystem of network side registration.Other CS operation flows such as note also are like this.
Special is that based on the TD visual telephone service of CS circuit domain, owing to need the TD network to carry, after the user made a call, application subsystem will call TD wireless telecommunications subsystem and the TD network carries out mutual and Data-carrying equally.And when called, the network equipment is set up link and bearer service according to terminal at the information (mainly being IMSI number that endpoint registration TD network uses) and the TD wireless telecommunications subsystem of terminal of network side registration.
When the user by browser on during the Internet, when the user imports address correlation in browser after, the signal strength signal intensity that application subsystem is inquired about current terminal TD network of living in by TD wireless telecommunications subsystem earlier.When application subsystem learns that network signal meets the demands, will set up based on the data link channel of the TD network line correlation service data interaction of going forward side by side by TD wireless telecommunications subsystem and corresponding with it network server device.When application subsystem learnt that network signal does not meet the demands, application subsystem will be initiatively substitutes the TD network by gsm wireless communication subsystem and corresponding with it network server device foundation based on the data link channel of GSM network and finishes business of networking.Certainly, when terminal is used the TD wireless telecommunications subsystem of acquiescence and the online of TD network, network signal decay to when not satisfying business need, the terminal applies subsystem will initiatively disconnect PDP data link based on the TD network by TD wireless telecommunications subsystem, and call the gsm wireless communication subsystem immediately and set up data link by terminal and GSM network, to keep the carrying out of business of networking.Otherwise, when terminal is used gsm wireless communication subsystem and the online of GSM network temporarily, application subsystem learns that by TD wireless telecommunications subsystem the TD network signal returns to when satisfying the data service requirement, can switch back the TD data link with the PDP data link of being correlated with again.
Other forms of data service is basic and similar by the flow process of browser online, does not do here and gives unnecessary details.But, MMS and PushMail (mail push service) mail service is owing to special P USH notification message mechanism in its operation flow, and the interaction flow when relevant multimedia message of passive reception and PushMail mail wants complicated.Because the PUSH notification message belongs to CS circuit domain category, network side will be sent to the terminal applies subsystem to relevant PUSH notification message by GSM network and GSM communication subsystem earlier, and the terminal applies subsystem is dispatched according to the current network situation and according to relevant PS business game again.
