Wherein, with the process of 2G/3G network communication, the read operation to this identification card is usually only performed; The write operation of identification card is comprised address list or note are written to identification card.
Application subsystem can at RIL(Radio interface Layer, radio interface layer) build a 2/3G service management module, when described double-network double-standby terminal start, the start of this service management module first in control 3G wireless telecommunications subsystem and 2G wireless telecommunications subsystem, then control another one start.In addition, this service management module can be used for preserving according to the type of service of 2 wireless telecommunications subsystem responsible and current signal strength signal intensity state after address list information that 2/3G wireless telecommunications subsystem reports when starting shooting and short message information, start, and adjustment business game is to realize CS, PS service distributing.
The strategy of above-mentioned CS, PS service distributing refers to: larger for 3G network bandwidth, be applicable to data service, and the accumulation of 2G network optimization is more, to good features of 2G business support such as voice, utilize 2G, 3G dual-network and dual-standby to realize PS(Packet Service in end side), CS(Circuit Service) service distributing (i.e. 2G network carrying CS business, 3G network carrying PS data service), evade the network coexisted problem brought of current 23G.
Particularly, when the user of described double-network double-standby terminal initiates business, described service management module selects network according to type of service, when initiated business is PS business, or when being the visual telephone service in CS business, described service management model choice 3G network, when initiated business is the CS business except visual telephone service, described service management model choice 2G network; When selected network meets the condition of signal strength signal intensity, the wireless telecommunications subsystem that selected network is corresponding carries out communication by selected network.
Wherein, 3G wireless telecommunications subsystem monitors the signal strength signal intensity of current 3G network, and the signal strength signal intensity of current 3G network is informed described service management module; When service management model choice 3G network, and when 3G network meets the condition of signal strength signal intensity, carry out communication by 3G network; When service management model choice 2G network, and when 2G network meets the condition of signal strength signal intensity, 2G wireless telecommunications subsystem carries out communication by 2G network.
Wherein, although visual telephone service is the business based on CS circuit domain, due to service bearer must be carried out by 3G network, so when user initiates visual telephone service, need selection 3 G network.
The above-mentioned condition meeting signal strength signal intensity refers to, the signal strength signal intensity of network can carry related service (being initiated business).During specific implementation, can be when the signal strength signal intensity of network is greater than appointed threshold value, judge the condition meeting signal strength signal intensity.
In the present invention, can adjust initiated PS business in the following way, comprise:
1, when initiated business is PS business, during described service management model choice 3G network, if the signal strength signal intensity of the current 3G network that described service management module monitors according to described 3G wireless telecommunications subsystem, when judgement cannot initiate described PS business, notify that described 2G wireless telecommunications subsystem activates the 2G data link of 2G network, initiate described business;
2, when initiated business is PS business, described 3G wireless telecommunications subsystem is undertaken by 3G network in the process of communication, if the signal strength signal intensity of the current 3G network that described service management module monitors according to described 3G wireless telecommunications subsystem, judge that the signal strength weakening of current 3G network is to when cannot carry described PS business, then described service management module notifies described 3G wireless telecommunications subsystem and 2G wireless telecommunications subsystem, by PDP(Packet Data Protocol corresponding for described PS business, packet data protocol) data link is switched to 2G data link from 3G data link.
3, when described 2G wireless telecommunications subsystem uses 2G data link to carry out PS business, when the signal strength signal intensity of the current 3G network that described service management module monitors according to described 3G wireless telecommunications subsystem, judge that the signal strength signal intensity of current 3G network is strengthened to when can carry described PS business, then described service management module notifies described 3G wireless telecommunications subsystem and 2G wireless telecommunications subsystem, and PDP data link corresponding for described PS business is switched to 3G data link from 2G data link.
During specific implementation, can be the signal strength signal intensity that service management module judges current 3G network, if be less than or equal to appointed threshold value, then judge cannot initiate described PS business or carry described PS business, if be greater than appointed threshold value, then judge to carry described PS business.Certainly, the appointed threshold value that above-mentioned three kinds of situations use can be equal, also can not wait.
In addition, be visual telephone service for initiated business, but the signal strength signal intensity of the current 3G network that service management module monitors according to described 3G wireless telecommunications subsystem, judgement cannot initiate the situation of described visual telephone service, this visual telephone service is fallen back to common speech business by service management module controls, reinforms 2G wireless telecommunications subsystem and initiates this speech business.
Above-mentioned 3G network can be TD network, WCDMA(Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) network, CDMA2000 network, 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, main is TD network with 3G network, 2G network is that GSM network is described, but be not limited thereto, 3G network and the 2G network of other type are applicable to the present invention too.
Be TD network below with 3G network, 2G network is that the application example of GSM network further describes.
As shown in Figure 2, this example uses " AP(application)+TD Modem(is wireless)+GSM Modem(is wireless) " the TD/GSM dual-network and dual-standby mobile phone of the three core frameworks 23G network carrying that realizes CS, PS business shunts, wherein AP part is responsible for the primary module of application, two wireless telecommunications subsystem TD Modem and GSM Modem be responsible for respectively with 2G, 3G network mutual.Jointly using the function of a SIM card in order to realize two wireless modules, increasing by 2 GPIO between two wireless Modems and controlling as to the concurrent operations of SIM card.Go out a 2/3G service management module at the RIL layer building of AP, when starting shooting, AP first powers on to one of them Modem, such as GSM Modem, and then powers on to TD Modem.There is the situation reading while write SIM card in 2 Modem in start process, at this time need by GPIO SIM card Read-write Catrol, such as when GSM Modem reads and writes SIM card, first GPIOa(first is controlled pin) draw high, such TD Modem is before read-write SIM card, first read the state of GPIOa, if be high, just wouldn't read and write; If be low, just read-write; In like manner, TD Modem, when reading and writing SIM card, first controls pin GPIOb(second) draw high, so just can notify that GSM Modem wouldn't read and write SIM card.By the effective control and management of GPIO to SIM card, two on realization theory independently wireless communication module access the function of same SIM card, reach the object of dual-network and dual-standby single deck tape-recorder odd numbers.
As shown in Figure 2, the device realizing 23G double-network double-standby terminal CS, PS service distributing based on dual-network and dual-standby single deck tape-recorder odd numbers of the present embodiment comprises with lower module:
A, AP(apply) subsystem
AP subsystem has the application processor module of separate CPU, it is the master control system of mobile phone terminal, that has been responsible for user is mutual, if user needs the operation carrying out wireless telecommunications aspect or SIM card aspect, is then responsible for controlling corresponding wireless telecommunication system by this system and completes correlation function.This subsystem comprises a service management module in this example, and this module has following functions:
1, by " CS business walks 2G network, and PS business walks 3G network " principle, each business is classified, when user initiates business, judge if CS business, then initiate from gsm wireless communication subsystem, if PS business, then initiate from TD wireless telecommunications subsystem.Wherein, in view of CS64kbps video telephone is the peculiar business of TD network, so visual telephone service is also initiated by TD wireless telecommunications subsystem.
2, the PS business game that TD network signal intensity is current to terminal residing for the monitoring of TD wireless telecommunications subsystem responsible adjusts.As:
When TD network signal intensity residing for the monitoring of TD wireless telecommunications subsystem is not enough to support initiation data services related, service management module activates 2G data link by gsm wireless communication subsystem and initiates related service.
When terminal is using the TD network of acquiescence to carry out in data service procedures, the network signal of present position die down to be not enough to support related service normally carry out time, relevant PDP data link is switched in the responsible 2G data link of gsm wireless communication subsystem by service management module in charge, to continue normally carrying out of related service.
B, gsm wireless communication subsystem
Gsm wireless communication subsystem, is responsible for carrying out alternately, carrying various CS business with GSM network, and is responsible for carrying out initial work to SIM, can comprise AT command interface layer and gsm wireless protocol stack.
1, gsm wireless communication subsystem comprises in this example of GSM Modem(, can think that gsm wireless communication subsystem is GSM Modem), the carrying of the whole terminal of primary responsibility all CS circuit domain business except video telephone, and carry data services related when TD signal is not good by the data link of 2G temporarily.
2, by GPIO, SIM read-write is controlled, before read-write SIM card, first judge the state of GPIOb, if be high, then do not read and write SIM card; If be low, then GPIOa drawn high, then read and write SIM card.After read-write SIM card terminates, then GPIOa is dragged down, to notify that TD Modem can read and write SIM card.
C, TD wireless telecommunications subsystem
TD wireless telecommunications subsystem responsible and TD network carry out alternately, carrying various PS business and video telephone function, can comprise AT command interface layer and TD radio protocol stack.
1, TD wireless telecommunications subsystem comprises in this example of TD Modem(, can think that TD wireless telecommunications subsystem is TD Modem).The TD Modem of the present embodiment is different from TD Modem commercial at present, and it does not possess TD/GSM bimodulus handoff functionality, is only operated in ' TD ONLY ' pattern.The data service of its primary responsibility based on TD network and the data interaction of visual telephone service.And the signal strength signal intensity monitoring of TD network residing for present terminal, when signal weak to certain value time, PS business is switched to GSM wireless telecommunications subsystem by notice AP application subsystem.
2, by GPIO, SIM read-write is controlled, before read-write SIM card, first judge the state of GPIOa, if be high, then do not read and write SIM card; If be low, then GPIOb drawn high, then read and write SIM card.After read-write SIM card terminates, then GPIOb is dragged down, to notify that GSM Modem can read and write SIM card.
D, SIM card module
Be inserted with a SIM card in SIM card module, in this SIM card, preserve the information of carrying out authentication for GSM network and TD network.
In start process, AP can first power on to one of them Modem, then powers on to another Modem, in power up initialization process, relates to two wireless Modems and can be solved by above-mentioned mode the concurrent operations of SIM card.Two wireless Modems finally complete the initialization of protocol stack according to respective independently initialize flow, by the IMSI(International Mobile Subscriber Identification Number of same SIM card, international mobile subscriber identity) report each self-corresponding TD network and GSM network.
For normal speech telephone service, when user is by dialing interface exhalation voice call, application subsystem is according to the logic of " CS business walks GSM network; PS business walks TD network ", call gsm wireless communication subsystem and GSM network is carried out alternately, and carry out business by GSM network carrying with the other side.Time called, the information (IMSI number of mainly endpoint registration GSM network use) that the network equipment is registered at network side according to terminal, and the gsm wireless communication subsystem of terminal establishes the link and bearer service.Other CS operation flows such as note are also like this.
It should be noted that, based on the TD visual telephone service of CS circuit domain, because needs TD network carries, after user makes a call, application subsystem will call TD wireless telecommunications subsystem and TD network carries out mutual and Deta bearer.And time called, the information (mainly the IMSI number of endpoint registration TD Web vector graphic) that the network equipment is registered at network side according to terminal, and the TD wireless telecommunications subsystem of terminal establishes the link and bearer service.
When user is by browser during the Internet, after user inputs address correlation in a browser, application subsystem is first by the signal strength signal intensity of TD network residing for TD wireless telecommunications subsystem inquiry present terminal.When application subsystem learns that network signal meets the demands, then to be gone forward side by side line correlation service data interaction by TD wireless telecommunications subsystem and the network server device corresponding with it data link channel set up based on TD network.When application subsystem learns that network signal does not meet the demands, application subsystem completes business of networking by initiatively carrying out alternative TD network by gsm wireless communication subsystem and network server device corresponding with it foundation based on the data link channel of GSM network.Certainly, when terminal uses TD wireless telecommunications subsystem and the online of TD network of acquiescence, when network signal decay to and does not meet business need, the PDP data link that terminal applies subsystem will initiatively be disconnected by TD wireless telecommunications subsystem based on TD network, and call gsm wireless communication subsystem immediately and set up data link by terminal and GSM network, maintain the carrying out of business of networking.Otherwise, when terminal Interim use gsm wireless communication subsystem and GSM network online, application subsystem by TD wireless telecommunications subsystem learn TD network signal return to meet data service requirement time, relevant PDP data link can be switched back TD data link again.
The basic flow process with being surfed the Net by browser of other forms of data service is similar, does not repeat here.But, MMS and PushMail(mail push service) mail service due to PUSH notification message special in its operation flow mechanism, passive reception be correlated with multimedia message and PushMail mail time interaction flow more complex.Because PUSH notification message belongs to CS circuit domain category, network side first will send to relevant PUSH notification message the application subsystem of terminal by GSM network and GSM communication subsystem, application subsystem is dispatched according to relevant PS business game according to current network conditions again.
