In the embodiment of the invention, can carry out service distributing, that is: bigger at the 3G network bandwidth, be fit to data service, and 2G network optimization work accumulation is more, to 2G business supports such as voice characteristics preferably, utilizes 2G, 3G dual-network and dual-standby to realize that PS (Packet Service), CS (Circuit Service) service distributing (are 2G network carrying CS business in end side, 3G network carrying PS data service), evade the network coexisted problem of bringing of current 23G.
Particularly, when the user of described dual-network and dual-standby terminal initiates business, described application subsystem is selected network according to type of service, when the business of being initiated is the PS business, when perhaps being the visual telephone service in the CS business, described application subsystem is selected 3G network, when the business of being initiated during for the business of the CS except that visual telephone service, and described application subsystem selection 2G network; When selected network satisfied the condition of signal strength signal intensity, the wireless telecommunications subsystem of selected network correspondence carried out communication by selected network.
Wherein, though visual telephone service is based on the business of CS circuit domain,, when the user initiates visual telephone service, need to select 3G network owing to must carry out service bearer by 3G network.
The above-mentioned condition that satisfies signal strength signal intensity is meant that the signal strength signal intensity of network can be carried related service (being the business of being initiated).During specific implementation, can be signal strength signal intensity when network during, judge the condition that satisfies signal strength signal intensity greater than the appointed threshold value.
In the present invention, can adjust the PS business of being initiated in the following way, comprise:
1, when the business of being initiated be the PS business, when described application subsystem is selected 3G network, if the signal strength signal intensity of the current 3G network that described application subsystem monitors according to described 3G wireless telecommunications subsystem, judgement can't be initiated described PS when professional, notify described 2G wireless telecommunications subsystem to activate the 2G data link of 2G network, initiate described business;
2, when the business of being initiated is the PS business, described 3G wireless telecommunications subsystem is undertaken in the process of communication by 3G network, if the signal strength signal intensity of the current 3G network that described application subsystem monitors according to described 3G wireless telecommunications subsystem, the signal strength weakening of judging current 3G network is to carrying described PS when professional, then described application subsystem is notified described 3G wireless telecommunications subsystem and 2G wireless telecommunications subsystem, professional corresponding PDP (Packet Data Protocol, the packet data protocol) data link of described PS is switched to the 2G data link from the 3G data link.
When 3, described 2G wireless telecommunications subsystem uses the 2G data link to carry out the PS business, the signal strength signal intensity of the current 3G network that monitors according to described 3G wireless telecommunications subsystem when described application subsystem, the signal strength signal intensity of judging current 3G network is strengthened to can carry described PS when professional, then described application subsystem is notified described 3G wireless telecommunications subsystem and 2G wireless telecommunications subsystem, and the professional corresponding PDP data link of described PS is switched to the 3G data link from the 2G data link.
During specific implementation, can be the signal strength signal intensity that application subsystem is judged current 3G network,, then judge and to initiate described PS business or carry described PS business,, then judge and to carry described PS business if greater than the appointed threshold value if smaller or equal to the appointed threshold value.Certainly, the employed appointed threshold value of above-mentioned three kinds of situations can equate, also can not wait.
In addition, at the business of being initiated is visual telephone service, but the signal strength signal intensity of the current 3G network that application subsystem monitors according to described 3G wireless telecommunications subsystem, judgement can't be initiated the situation of described visual telephone service, application subsystem control is fallen back to common speech business with this visual telephone service, reinforms 2G wireless telecommunications subsystem and initiates this speech business.
Above-mentioned 3G network can be TD network, WCDMA (Wideband Code Division MultipleAccess, Wideband Code Division Multiple Access (WCDMA)) network, CDMA2000 network, the 2G network can be GSM network, CDMA (Code Division Multiple Access, code division multiple access) network etc., in embodiments of the invention and application example, it mainly is the TD network with the 3G network, the 2G network is described for the GSM network, but be not limited thereto, the 3G network of other type and 2G network are applicable to the present invention too.
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, the TD/GSM dual-network and dual-standby mobile phone of this example utilization " AP (application)+TD Modem (wireless)+GSM Modem (wireless) " three nuclear frameworks is realized the 23G network carrying shunting of CS, PS business, wherein AP partly is the primary module of be responsible for using, and two wireless telecommunications subsystem TDmodem and GSM modem are responsible for mutual with 2G, 3G network respectively.In order to realize the common function of using a SIM card of two wireless modules, because the user uses the frequency of CS business more than using PS traffic frequencies height, so sim card slot (identification module) is articulated on the GSM Modem wireless telecommunications subsystem.Go out a SIM Proxy at the RIL of AP subsystem layer building, when the AP subsystem is started shooting to GSM MODEM, GSMmodem can directly visit SIM card, and the data of SIM card are saved among the SIM Proxy of AP subsystem by the AT order, and TD Modem is by the SIM Proxy visit SIM card of visit AP, on the realization theory two independently wireless communication module visit the function of same SIM card, reach the purpose of dual-network and dual-standby single deck tape-recorder odd numbers.
As shown in Figure 2, the device based on dual-network and dual-standby single deck tape-recorder odd numbers realization 23G dual-network and dual-standby terminal CS, PS service distributing of present embodiment comprises with lower module:
A, AP (application) subsystem
The AP subsystem has the application processor module of separate CPU, it is the master control system of mobile phone terminal, be responsible for finishing mutual with the user,, then be responsible for controlling corresponding wireless telecommunication system and finish correlation function by this system if the user need carry out the operation of wireless telecommunications aspect or SIM card aspect.This subsystem has following function in this example:
By " the CS business is walked the 2G network, and the PS business is walked 3G network " principle, each business is classified, when the user initiates business, judge if the CS business is then initiated from the gsm wireless communication subsystem, if the PS business is then initiated from TD wireless telecommunications subsystem.Wherein, in view of the CS64kbps video telephone is the peculiar business of TD network, so visual telephone service also is to initiate by TD wireless telecommunications subsystem.
Application subsystem manages the relevant information that two wireless telecommunications subsystems relate to SIM card by SIM proxy.
TD network signal intensity of living in according to the monitoring of TD wireless telecommunications subsystem responsible is adjusted the current PS business game of terminal.As:
When the TD network signal intensity of living in of TD wireless telecommunications subsystem monitoring was not enough to support the initiation data services related, application subsystem can activate the 2G data link by the gsm wireless communication subsystem initiate related service.
Using the TD network of acquiescence when terminal carries out in the data service process, the network signal of present position dies down when being not enough to support related service and normally carrying out, application subsystem is responsible for relevant PDP data link is switched on the responsible 2G data link of gsm wireless communication subsystem, with normally carrying out of continuity related service.
B, gsm wireless communication subsystem
The gsm wireless communication subsystem is responsible for carrying out carrying various CS business alternately with the GSM network, and is responsible for SIM is carried out initial work, can comprise AT command interface layer and gsm wireless protocol stack.
The gsm wireless communication subsystem comprises that GSM Modem is (in this example, can think that the gsm wireless communication subsystem is GSM Modem), the main carrying of being responsible for 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.
In start process, the gsm wireless communication subsystem is responsible for the initialization SIM card, and the most parameter of SIM card is read and is kept among the SIM Proxy of AP subsystem, as PLMN sign, TMSI, LAI etc., preparation allows TD wireless telecommunications subsystem visit, and finishes the network registry of TD wireless telecommunications subsystem.
The gsm wireless communication subsystem is responsible for the data sync between SIM proxy and the SIM card.
C, TD wireless telecommunications subsystem
TD wireless telecommunications subsystem responsible and TD network carry out carrying various PS business and video telephone function alternately, can comprise AT command interface layer and TD radio protocol stack.
TD wireless telecommunications subsystem comprises TD Modem (in this example, can think that TD wireless telecommunications subsystem is TD Modem).The TD Modem of present embodiment is different from commercial at present TDModem, and it does not possess TD/GSM bimodulus handoff functionality, only is operated in ' TD ONLY ' pattern.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 monitoring, when a little less than the signal during to certain value, notice AP application subsystem switches to the gsm wireless communication subsystem with the PS business.
TD wireless telecommunications subsystem side orders the most of parameter of the SIM proxy that reads the AP subsystem to carry out initialization by AT when start, does not need directly to visit SIM card, can save initialization time.Still need TD modem to initiate the AT order to GSM side SIM card asynchronous access but relate to identifying algorithm (network side needs the IMSI information of SIM card), need usually to guarantee that 200ms finishes with interior, so the channels drive of hardware will guarantee rate requirement by AP.
D, SIM card module
Be inserted with a SIM card in the SIM card module, preserve in this SIM card and be used for the information that GSM network and TD network carry out authentication.
In the opening initialization process, because SIM card is actually and is articulated on the GSM Modem, TD modem visits SIM card by virtual mode, so in start process, at first tackling GSMModem powers on, finish the SIM card initialization earlier by GSM Modem, be responsible for the most parameter of SIM card is read among the SIM Proxy that is kept at the AP subsystem, as PLMN sign, TMSI, LAI etc.Afterwards TD Modem is powered on, TD Modem orders relevant parameters among the SIMProxy that reads the AP subsystem by AT, the initialization flow process of initiation protocol stack again, relating to identifying algorithm still needs TDmodem to pass through the AP subsystem again by GSM asynchronous access SIM card, finally IMSI number of same SIM card can be reported each self-corresponding TD network and GSM network.
With the normal speech telephone service is example, 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.
Need to prove 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.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, 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 again.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, kept 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 earlier sent to the application subsystem of terminal to relevant PUSH notification message by GSM network and GSM communication subsystem, and application subsystem is dispatched according to the current network situation and according to relevant PS business game again.
