Description
Technical field
The present invention relates to mobile communication terminal, particularly relate to a kind of many card multimode terminals and access module method for synchronous and device.
Background technology
In second generation mobile communication (2G) technology, global system for mobile communications (GSM, Globe System of Mobile Communication), and evolution system General Packet Radio System (GPRS, General Packet Radio System), strengthening data rate GSM business (EDGE, Enhanced Data rates for GSM service) is one of most widely used in the world mobile communication system.At present, along with popularizing gradually of 3G (Third Generation) Moblie (3G) technology, for example based on Time Division-Synchronous Code Division Multiple Access access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) the 3G business of technology is carried out in the whole nation, increasing people brings into use 3G mobile, but owing to use the crowd of 2G mobile phone still to occupy the majority after all, in the transition stage of 2G to 3G, with a subscriber equipment (UE, User Equipment) standby that realizes 2G and 3G simultaneously then can seem quite convenient, and therefore many card multimode terminals arise at the historic moment.
The 3G system also comprises Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband CDMA), and the evolution system of 3G is Long Term Evolution (LTE, a Long Term Evolution) system.
Employed many terminal cards of terminal, typically refer to SIM card (Subscriber Identity Module, client identification module card), usim card (Universal Subscriber Identity Module, the global customers identification module card) or UIM card (User Identity Model, subscriber identification module).
The multimode that terminal is supported is often referred to and supports GSM/GPRS/EDGE, TD-SCDMA, WCDMA, the access technology that two or more among the LTE are different.
With two card dual-mode terminals is example, along with the variation of wireless environment on every side, terminal card can switch to the sub-district (by the automatic gravity treatment triggering of UE or by network-triggered) of another kind of network schemer automatically from a kind of sub-district of network schemer, just switch to another access technology (for example: automatically switch to the TD-SCDMA pattern) from the GSM pattern from a kind of access technology, so for double-terminal, two cards can switch by independent implementation pattern, if but two independent fully switchings of card, uncorrelated mutually, these terminal cards resident (Camping) and the pattern of being worked and roaming between different mode and handoff procedure, in the specified standard of normal structures such as 3GPP, clear and definite regulation is arranged all.When a certain card resident environmental changes such as district wireless signals intensity when satisfying the trigger condition of agreement regulation, terminal can be roamed between different access technologies or switch, and makes this card resident and work on the another one pattern.So very likely two cards are in different access technology patterns, and this just needs the hardware device of terminal to support two kinds of different access technologies simultaneously.The method of associated terminal card gravity treatment can be the Chinese invention patent application of CN 101583167A with reference to publication number, and this patent application discloses a kind of method of cell reselection and device.
Roam between different patterns or switch conversion between the isotype, roaming ordinary representation terminal works is in idle condition, as holding state; Switch the ordinary representation terminal works in connection status, as talking state.But be commonly referred to as the switching between the pattern sometimes, and the operating state of distinguishing terminal not,, and judge and belong to the above the switching of roaming or agreement according to the state of terminal works at that time.
In addition, for the many cards multimode terminal that only uses a cover communication module (comprising radio frequency chip and baseband processing chip), if many terminal cards reside in different sub-districts, paging reception and nearby region measurement at each sub-district can only adopt the mode of timesharing to switch in turn, many terminal cards reside in its paging receiving efficiency on the different sub-districts respectively and are inversely proportional to the card number of standby simultaneously usually, can reduce along with the increase of the card number of while standby the measuring machine of adjacent area.
For power consumption, because every terminal card resides on the different sub-districts separately, need timesharing on different sub-districts, to carry out paging reception and nearby region measurement in turn, the free time of terminal will be lacked a lot, and correspondingly power consumption will be than higher.

If described other-end card switches to the failure of described second sub-district, then control other sub-districts that described other-end card switches to described second network schemer.
If described other-end card switches to other sub-district failures of described second network schemer, then control described other-end card and switch to other sub-districts of described first network schemer or continue to reside in current area.
In addition, after described other-end card switching cell finishes, successful switch other sub-districts for example to described second sub-district or successful switch to second network schemer or first network schemer, perhaps continue to reside in current area, can recover the action before described other-end card interrupts according to the current state information of the described other-end card that writes down.
Described first network schemer is a kind of in TD-SCDMA pattern, WCDMA pattern, LTE pattern and the GSM pattern, and described second network schemer is the another kind in TD-SCDMA pattern, WCDMA, LTE pattern and the GSM pattern.
Be that example is elaborated with two card dual-mode handsets below, in the present embodiment, terminal card 1 is installed two card dual-mode handsets and 2, two cards of terminal card can be operated in the sub-district of GSM pattern or the sub-district of TD-SCDMA pattern.
The terminal card 1 current sub-district 1 that resides in the TD-SCDMA pattern, the terminal card 2 current sub-districts 2 that reside in the TD-SCDMA pattern please refer to Fig. 2, at first carry out step S11, and switch the be triggered sub-district of rete mirabile network pattern of terminal card 1.
Be triggered situation that the sub-district switches of terminal card can comprise that the sub-district that two card dual-mode handsets trigger automatically and terminal card is resident triggers, and specifically, the situation that triggering terminal sticks into the switching of capable rete mirabile network sub-district under the TD-SCDMA pattern can be one of the following:
(1) mobile phone triggers gravity treatment automatically, is meant under holding state, by rete mirabile network nearby region measurement, finds to be more suitable for resident GSM sub-district;
(2) switching is triggered in resident sub-district: when inserting on the TD-SCDMA pattern, receive the RRC CONNECT REJ message of the base station transmission of sub-district, indication is redirected to the GSM sub-district in this message;
(3) switching is triggered in resident sub-district: switch in circuit domain/data field (CS/PS) communication process, refer to because network finds to have the GSM sub-district (more suitably standard is: signal is stronger or the network element device load is more sufficient) of the more suitable CS/PS of carrying out business, network can require terminal to switch so.
In the present embodiment, terminal card 1 is triggered and switches to the sub-district A (second sub-district) of GSM pattern from the sub-district 1 of TD-SCDMA pattern (first sub-district).
Step S12, control terminal card 1 switches to sub-district A.Triggering terminal card 1 is selected the sub-district A of GSM pattern and is attempted persistent district A, promptly attempts receiving the system message of sub-district A.
Step S13, control terminal card 2 enters interrupt status.Control terminal card 2 enters interrupt status and comprises: send interrupt message to terminal card 2; After terminal card 2 receives described interrupt message, interrupt the current action of terminal card 2, the current state information of record terminal card 2.The execution sequence of step S12 and S13 can be not limited to the order that present embodiment limits, in other embodiments, also can first execution in step S13 execution in step S12 again, perhaps begin execution in step S12 and S13 simultaneously.
Step S14, whether successful switch is to sub-district A to judge terminal card 1, if then carry out step S15, then carries out step S16 if not.Terminal card 1 successful switch is that terminal card 1 successfully resides in sub-district A and is meant that terminal card 1 receives whole system messages of sub-district A to sub-district A, and can judge according to system message: the received signal intensity of this sub-district meets the minimum access thresholding of network requirement, lane place under the sub-district is not under an embargo, the sub-district does not get clogged (bar), and the network No. of sub-district belongs to the network of terminal card 1 operator.Switch in the process of sub-district A at terminal card 1, terminal card 1 can be stored the system message of the sub-district A that receives.If terminal card 1 resides in sub-district A, then carry out step S15; If step S16 is then carried out in terminal card 1 persistent district A failure.
Step S15, control terminal card 2 switches to sub-district A, then carries out step S17.If terminal card 1 successfully resides in sub-district A, then force terminal card 2 to switch to sub-district A.After the success of terminal card 1 switching cell, triggering terminal card 2 carries out the sub-district and switches, terminal card 2 is attempted persistent district A, because terminal card 1 successfully resides in sub-district A, terminal card 1 has been stored the system message of sub-district A, terminal card 2 does not need to receive again the system message of sub-district A, can the shared terminal card system message of sub-district A of 1 storage, promptly directly read the system message of sub-district A from terminal card 1, judge that according to system message terminal card 2 whether can persistent district A then, for example whether the network No. of sub-district A belongs to the network of terminal card 2 operators.
Step S16, control terminal card 1 switch to other sub-districts or continue to reside in sub-district 1.If terminal card 1 persistent district A failure, then terminal card 1 can be resident to other sub-districts or continue to reside in sub-district 1 by modes such as automatic gravity treatments, decide according to the actual residing wireless environment of terminal the sub-district that terminal card 1 switches, can be the sub-district of TD-SCDMA pattern, also can be the sub-district of GSM pattern.If terminal card 1 switches to other sub-districts, can also triggering terminal card 2 switch to the sub-district of identical network pattern.
Step S17, whether successful switch is to sub-district A to judge terminal card 2, if then finish, then carries out step S18 if not.If it is resident that sub-district A can be fit to terminal card 2, terminal card 2 can arrive sub-district A by successful switch, terminal card 1 and terminal card 2 reside in the same sub-district of identical network pattern simultaneously like this, be the sub-district A of GSM pattern, realized that thus two cards switch to the identical network sub-district of same access technology synchronously.
Step S18, control terminal card 2 switch to other sub-districts or continue to reside in sub-district 2.If it is resident that sub-district A is not suitable for terminal card 2, terminal card 2 persistent district A failure, then terminal card 2 can be resident to other sub-districts or continue to reside in sub-district 2 by modes such as automatic gravity treatments, decide according to the actual residing wireless environment of terminal the sub-district that terminal card 2 switches, can be the sub-district of TD-SCDMA pattern, also can be the sub-district of GSM pattern.In the present embodiment, the sub-district that terminal card 2 switches can be to belong to identical network schemer with the resident sub-district of terminal card 1, if promptly terminal card 1 resides in the sub-district of GSM pattern, then terminal card 2 switches to the sub-district of suitable GSM pattern; If terminal card 2 resides in the sub-district of TD-SCDMA pattern, then terminal card 2 switches to the sub-district of suitable TD-SCDMA pattern; The access technology that so also can realize two terminal card persistent districts is synchronous.
Above-mentioned flow process is the process of terminal card from the TD-SCDMA mode switch to the GSM pattern, please continue with reference to figure 3, below goes on to say the process of terminal card from the GSM mode switch to the TD-SCDMA pattern.
Terminal card 1 and the terminal card 2 current sub-district A that reside in the GSM pattern at first carry out step S21, and switch the be triggered sub-district of rete mirabile network pattern of terminal card 2.
Be triggered situation that the sub-district switches of terminal card can comprise that the sub-district that two card dual-mode handsets trigger automatically and terminal card is resident triggers, and specifically, the situation that triggering terminal sticks into the switching of capable rete mirabile network sub-district under the GSM pattern can be one of the following:
(1) mobile phone triggers gravity treatment automatically, is meant under holding state, by rete mirabile network nearby region measurement, finds to be more suitable for resident TD-SCDMA sub-district;
(2) switching is triggered in resident sub-district: when inserting on the GSM pattern, receive PCCO (the packet cell change order) message of the base station transmission of sub-district, indication is redirected to the TD-SCDMA sub-district in this message;
(3) switching is triggered in resident sub-district: switch in the CS/PS communication process, refer to because network finds to have the TD-SCDMA sub-district (more suitably standard is: signal is stronger or the network element device load is more sufficient) of the more suitable CS/PS of carrying out business, network can require terminal to switch so;
(4) resident sub-district is triggered and is switched: connect network when discharging in the GSM circuit domain and require terminal to switch on the sub-district of appointment (fast return process) in release command.
In the present embodiment, terminal card 2 is triggered and switches to the sub-district 3 (second sub-district) of TD-SCDMA pattern from the sub-district A of GSM pattern (first sub-district).
Step S22, control terminal card 2 switches to sub-district 3.Triggering terminal card 2 is selected the sub-district 3 of TD-SCDMA pattern and is attempted persistent district 3, promptly attempts receiving the system message of sub-district 3.
Step S23, control terminal card 1 enters interrupt status.Control terminal card 1 enters interrupt status and comprises: send interrupt message to terminal card 1; After terminal card 1 receives described interrupt message, interrupt the current action of terminal card 1, the current state information of record terminal card 1.The execution sequence of step S22 and S23 can be not limited to the order that present embodiment limits, in other embodiments, also can first execution in step S23 execution in step S22 again, perhaps begin execution in step S22 and S23 simultaneously.
Step S24, judge terminal card 2 whether successful switch if then carry out step S25, then carry out step S26 if not to the sub-district 3.Terminal card 2 successful switch 3 are that terminal card 2 successfully resides in sub-district 3 and is meant that terminal card 2 receives whole system messages of sub-district 3 to the sub-district, and can judge according to system message: the received signal intensity of this sub-district meets the minimum access thresholding of network requirement, lane place under the sub-district is not under an embargo, the sub-district does not get clogged (bar), and the network No. of sub-district belongs to the network of terminal card 2 operators.Switch in the process of sub-district 3 at terminal card 2, terminal card 2 can be stored the system message of the sub-district 3 that receives.If terminal card 2 resides in sub-district 3, then carry out step S25; If step S26 is then carried out in 3 failures of terminal card 2 persistent districts.
Step S25, control terminal card 1 switches to sub-district 3, then carries out step S27.If terminal card 2 successfully resides in sub-district 3, then force terminal card 1 to switch to sub-district 3.Behind terminal card 2 handover success, triggering terminal card 1 carries out the sub-district and switches, terminal card 1 is attempted persistent district 3, because terminal card 2 successfully resides in sub-district 3, terminal card 2 has been stored the system message of sub-district 3, terminal card 1 does not need to receive again the system message of sub-district 3, can the shared terminal card system message of sub-district 3 of 2 storages, promptly directly read the system message of sub-district 3 from terminal card 2, judge that according to system message terminal card 1 whether can persistent district 3 then, for example whether the network No. of sub-district 3 belongs to the network of terminal card 1 operator.
Step S26, control terminal card 2 switch to other sub-districts or continue to reside in sub-district A.If terminal card 2 persistent districts 3 failures, then terminal card 2 can be resident to other sub-districts or continue to reside in sub-district A by modes such as automatic gravity treatments, decide according to the actual residing wireless environment of terminal the sub-district that terminal card 2 switches, can be the sub-district of TD-SCDMA pattern, also can be the sub-district of GSM pattern.If terminal card 2 switches to other sub-districts, can also triggering terminal card 1 switch to the sub-district of identical network pattern.
Step S27, judge terminal card 1 whether successful switch if then finish, then carry out step S28 if not to the sub-district 3.If it is resident that sub-district 3 can be fit to terminal card 1, terminal card 1 can arrive sub-district 3 by successful switch, terminal card 1 and terminal card 2 reside in the same sub-district of identical network pattern simultaneously like this, be the sub-district 3 of TD-SCDMA pattern, realized that thus two cards switch to the network cell of same access technology synchronously.
Step S28, control terminal card 1 switch to other sub-districts or continue to reside in sub-district A.If it is resident that sub-district 3 is not suitable for terminal card 1,3 failures of terminal card 1 persistent district, then terminal card 1 can be resident to other sub-districts or continue to reside in sub-district A by modes such as automatic gravity treatments, decide according to the actual residing wireless environment of terminal the sub-district that terminal card 1 switches, can be the sub-district of TD-SCDMA pattern, also can be the sub-district of GSM pattern.In the present embodiment, the sub-district that terminal card 1 switches can be to belong to identical network schemer with the resident sub-district of terminal card 2, if promptly terminal card 2 resides in the sub-district of GSM pattern, then terminal card 1 switches to the sub-district of suitable GSM pattern; If terminal card 2 resides in the sub-district of TD-SCDMA pattern, then terminal card 1 switches to the sub-district of suitable TD-SCDMA pattern; The access technology that so also can realize two terminal card persistent districts is synchronous.
Above-mentioned flow process can realize that two terminal cards switch to a kind of access technology as much as possible synchronously, such two card standbies in one mode and carry out business (for example paging is answered, caller dialing etc.).
Need to prove, the foregoing description is to be that example has been described in detail with two card dual-mode handsets, in fact, the technical scheme of embodiment of the present invention is applicable to that equally also many cards multimode terminal of supporting more than two terminal cards above (for example three cards, four cards) and the two kinds of network schemers switches to the sub-district of another kind of network schemer from a kind of sub-district of network schemer, in many terminal cards, there is a terminal card to be triggered and switches to the sub-district of another kind of network schemer, then force the other-end card to switch to (attempting resident) identical sub-district.Further, can specify the terminal card that is triggered is main card, main card carries out rete mirabile network sub-district earlier and switches, the other-end card carries out the switching of rete mirabile network sub-district more then, the switching of other-end card also is another Zhang Jinhang switching again after the finishing switching, avoided like this switching conflict, improved switching efficiency.
In addition, the mode switch of above-mentioned many card multimode terminals are to be that example describes with TD-SCDMA and GSM mode switch, switching that in fact also can other network schemers.For example, be applicable to WCDMA and GSM mode switch, perhaps TD-SCDMA and WCDMA mode switch, its process is roughly the same, just the situation of triggering terminal card switching cell is slightly different according to the network schemer at actual place, for example, if from the WCDMA mode switch to the GSM pattern or the TD-SCDMA pattern, the terminal card situation of switching that is triggered can be one of the following:
(1) mobile phone triggers gravity treatment automatically, is meant under holding state, by rete mirabile network nearby region measurement, finds to be more suitable for resident GSM sub-district or TD-SCDMA sub-district;
(2) switching is triggered in resident sub-district: when inserting on the WCDMA pattern, receive the RRC CONNECT REJ message of the base station transmission of sub-district, indication is redirected to GSM sub-district or TD-SCDMA sub-district in this message;
(3) switching is triggered in resident sub-district: switch in circuit domain/data field (CS/PS) communication process, refer to because network finds to have GSM sub-district or TD-SCDMA sub-district (more suitably standard is: signal is stronger or the network element device load is more sufficient) of the more suitable CS/PS of carrying out business, network can require terminal to switch so.
The access module method for synchronous of corresponding above-mentioned many card multimode terminals, the embodiment of the invention also provide a kind of access module synchronizer of many card multimode terminals, and as shown in Figure 4, the access module synchronizer 4 that blocks multimode terminal comprises more:
