Abstract
The invention provides a method and a terminal for residing a network. When the terminal needs to perform business, a network which can support the terminal's business to be performed is chosen to perform the business, so that when the terminal is standby and the networks that perform the terminal's business are different, for each time the terminal performs the business, system overhead of returning to the network in which the terminal is standby is reduced at least once. When the terminal needs to use the different networks from the network in which the terminal is standby for a plurality of times, the returning overhead is reduced, meanwhile, the overhead of accessing to the network for performing the business from the network in which the terminal is standby is also possibly reduced. Therefore, frequency of interoperate among the networks is greatly reduced, load of the networks is reduced, and reduction of paging call completing rate of a user caused by frequent intersystem re-selection is prevented.
Description
Technical field
The present invention relates to communication technical field, relate in particular to resident method of a kind of network and terminal.
Background technology
Along with developing rapidly of the communication technology, legacy networks such as GSM network, TD-SCDMA network are ripe gradually, and in order to promote network communications capability; Produced multiple new network again; Like the LTE network, therefore various types of networks (comprising legacy network and various new network) are present in the communication system, simultaneously; In communication system, the terminal selects the network of which kind of type to communicate becomes a problem of needing solution badly.
To this problem, point out in the standard agreement, can priority be set for various networks of different type; Priority level is divided into 0～7 totally eight grades from low to high, and issues the network priority configuration information through broadcast, and the terminal is after listening to broadcast; Can be according to the priority of network; And near the network supported of sub-district, preferentially resident in the high-priority network corresponding district, thus be implemented in the resident of high-priority network.
In the prior art, be generally the high more priority of the strong more network settings of communication capacity, make the terminal preferentially resident in the strong network of communication capacity.But; There is partial service prematurity still usually in some network (like the new network of some new construction) in the construction period, covers not congruent defective; Need through with other internetwork interoperability behaviors, could fully ensure the business continuance and the seamless covering of communicating by letter at terminal, so the terminal usually can covering Network Based or business demand; Utilize circuit domain dropping (CSFB; Circuit SwitchedFall Back) technology, the resident or execution business through the more weak network of falling (like gravity treatment, switching) mode access communications ability is after the network coverage that standby service finishes or communication capacity is stronger recovers; The terminal will be according to the precedence information that issues in the broadcast, and the network that is back to high priority is resident.
Perhaps; Can be the priority that condition is come setting network also according to network coverage, network design integrity; The high more priority of network settings wider for network coverage, that network design is perfect more makes in the network that the terminal is preferentially wide at network coverage, network design is perfect resident.But some network (like some legacy network) is because communication capacity is limited, also need through with other internetwork interoperability behaviors, could fully ensure the business at terminal, like the normal execution of video call service.Therefore the terminal usually can be based on business demand; Mode access network coverage is narrow more through falling after rise, the incomplete relatively network of network design is carried out professional; After standby service finished, the terminal will be according to the precedence information that issues in the broadcast, and the network that is back to high priority is resident.
Be illustrated in figure 1 as in the prior art, carry out the resident sketch map of network, suppose to exist simultaneously in the communication system LTE network; TD-SCDMA network and GSM network, according to the rule of the high more priority of the strong more network settings of communication capacity, if priority from low to high respectively by 0～7 totally 8 grades represent; The priority that then can set the LTE network is 7; The priority of TD-SCDMA network is 3, and the priority of GSM network is 0, and then the terminal is carried out the resident flow process of network and specifically comprised in the prior art:
The first step, terminal can be searched for, measured each sub-district according to the network of self supporting after start, and in the network of selecting self to support, the best network corresponding district of signal quality inserts, thereby inserts the best network of signal quality.
In this step, if the terminal is supported LTE network, GSM network and TD-SCDMA network simultaneously, then the best network insertion of signal quality in LTE network, GSM network and the TD-SCDMA network is selected in the terminal after start, for example inserts the LTE network.
Second step, terminal monitoring cell broadcast messages according to the priority configuration information in the broadcast, are initiated the measurement to highest priority network.
In communication system as shown in Figure 1; The priority of each network is followed successively by LTE network, TD-SCDMA network and GSM network from high to low; In this step, the highest LTE network of access priority will be attempted in the terminal, thereby be implemented in standby in the highest network of priority.
If terminal GSM network in the first step, then in this step, the measurement to the LTE network can be at first initiated at the terminal, and it is resident after the LTE signal strength signal intensity satisfies certain condition, to access to the LTE network of limit priority.
If the measurement result of LTE network is found that the LTE signal strength signal intensity can not satisfy access conditions; Then the terminal continues the TD-SCDMA network is measured; When the TD-SCDMA signal strength signal intensity satisfies access conditions, the terminal will be inserted the TD-SCDMA network earlier, and constantly initiate the measurement to the LTE network.
If what the terminal inserted in the first step is the TD-SCDMA network, then in this step, the measurement to the LTE network can be initiated in the terminal, and it is resident after the LTE signal strength signal intensity satisfies certain condition, to access to the LTE network of limit priority.
If the LTE network is inserted at the terminal in the first step, then there be not the network higher in the cell broadcast messages than LTE network priority, the terminal can not initiate to measure to other networks so, but resident in the LTE network always.
The 3rd step, terminal are carried out professional.
Suppose that the terminal resides in the LTE network in a last step, then in a single day the terminal has data traffic requirement, but the high-speed transfer service that very first time acquisition LTE network provides, and after business is finished, continue to reside in the LTE network.
And in a single day the terminal has the voice service demand, because LTE network technology prematurity still at present, directly voice-over is professional; As among Fig. 12, shown in 4, the terminal will be fallen after rise to TD-SCDMA network or GSM network by the LTE network, in TD-SCDMA network or GSM network, carry out voice service; And after business is finished, as among Fig. 11, shown in 3, once more the LTE network is measured; When the LTE signal strength signal intensity satisfied certain condition, it was resident to return the LTE network again.
Need to prove; In second step went on foot with the 3rd, the terminal was in the resident process of LTE network, in case the LTE network coverage area is left at the terminal; Be that current LTE signal quality is when being lower than a certain thresholding; As among Fig. 12, shown in 4, the measurement to other low priority networks can be initiated in the terminal, and falls after rise and access to low priority network corresponding district.But in case monitor the LTE network of limit priority again; As among Fig. 11, shown in 3, the terminal can be initiated the measurement to the LTE network again, when satisfying the LTE signal strength signal intensity and satisfy access conditions; Return the LTE network, thereby realization resides in the purpose of the LTE network of high priority as far as possible.
Equally; The terminal is if insert the GSM network after leaving the LTE network; Return once more the process of LTE network from the GSM network at the terminal, if the LTE signal strength signal intensity can not satisfy access conditions, but the TD-SCDMA signal strength signal intensity satisfies access conditions; Then the terminal will be inserted the TD-SCDMA network earlier, and constantly initiate the measurement to the LTE network.
In the above-mentioned prior art, the problem that the scheme of terminal processes rete mirabile network interoperability exists is:
The scheme in the first step～the 3rd step can find out that start is to carrying out in the professional process certainly at the terminal, and the network that belongs to when network of selecting during as if starting up of terminal and terminal standby is a various network; And when professional network is carried out at the network that belongs to during terminal standby and terminal also for various network, the terminal will be carried out three networks at least and come and gone, the business that especially can't carry out at high-priority network for the core business that needs often to carry out (as; The voice service that the LTE network can't be carried out); And cover the border district signal fashion of the high-priority network (time bad) at high-priority network, and all will cause the terminal constantly to be travelled to and fro between between the various network, carry out operations such as network falling, measurement and gravity treatment continually; Make that the frequency of interoperability is high between the heterogeneous networks; Produce a large amount of signaling consumptions, emphasis network burden, waste Internet resources; Simultaneously, when carrying out network (sub-district) gravity treatment, for network; The terminal is in unreachable state, and promptly the terminal can not be paged, and network (sub-district) reselection operation need be repeatedly carried out at the terminal of existing scheme; Therefore also can influence paging call completing rate largely, reduce network service quality.
And be that condition comes the priority of setting network to have the problems referred to above too according to network coverage, network design integrity; And because change has taken place in imposing a condition of network priority; The priority of each network also must change, and therefore, the service propelling mechanism of network side also corresponding variation need take place; And network side transformation is adapted to new service propelling mechanism; The difficulty of implementing is bigger, and also can influence stability of network to the transformation of network side, and the business that influences the terminal is carried out.
Summary of the invention
The embodiment of the invention provides resident method of a kind of network and terminal, thereby solves the height of the interoperability frequency between the network in the prior art, causes the burden of network big, and the low problem of paging call completing rate.
The method that a kind of network is resident, this method comprises:
Whether terminal judges first network that resides in first network support terminal business to be carried out;
First network is being judged not during to be carried out professional of support terminal in the terminal, from the network that the terminal can be inserted, confirms second network of business can support terminal to be carried out; And
Access and after the business said to be carried out that in second network, is finished, continues to reside in second network in second network.
A kind of terminal, this terminal comprise first judge module, second judge module and insert resident module, wherein:

Embodiment
In order to solve in the prior art,, carry out operations such as network falling, measurement and gravity treatment continually because the terminal is constantly travelled to and fro between between the various network; Interoperability frequency between the network that is caused is high, causes the burden of network big, and the low problem of paging call completing rate; The scheme that the embodiment of the invention provides is from the terminal; End side is transformed, and it is provided by the invention at terminal idle state (during terminal standby) with carry out the access, resident of network when professional to utilize the terminal to be implemented in, and reduces the number of times that various network is travelled to and fro between at the terminal; Thereby the interoperability frequency between the reduction network solves the technical problem that the present invention proposes.Simultaneously, the difficulty of the terminal being transformed enforcement is less, realizes fairly simplely, and can not influence stability of network.
Through each embodiment and accompanying drawing technical scheme of the present invention is elaborated below.
Embodiment one,
The embodiment of the invention one provides a kind of network resident method, and the steps flow chart of this method is as shown in Figure 2, specifically may further comprise the steps:
Whether step 101, terminal judges first network support terminal business to be carried out.
Wait to carry out professional network priority configuration information and be meant to said,, supports saidly to wait to carry out in the professional network, the said magnitude relationship of waiting the tenability of the business of carrying out to business to be carried out.
In this step, the terminal that resides in first network judges whether the network that self belongs to supports the business that self is to be carried out when needs are carried out business; Specifically comprise: judge whether first network reaches setting priority to the said priority of carrying out business of waiting; If do not reach, then confirm not support terminal business to be carried out of first network, continue execution in step 102; Otherwise confirm first network support terminal business to be carried out, in first network, carry out business said to be carried out.
Wait to carry out professional to said in the network that said setting priority can insert for the terminal, prioritization is at the network of preceding M position, and M is a positive integer.As, set M=3, according to being directed against the said professional network priority configuration information of waiting to carry out; Can judge that then whether first network is in the network that can insert of terminal; To business to be carried out, prioritization is at preceding 3 network: if not, then continue execution in step 102; If then in first network, carry out business said to be carried out.
Step 102, terminal are confirmed to be used to carry out to wait to carry out the second professional network.
This step specifically comprises: the terminal is according to the said professional network priority configuration information of having stored of waiting to carry out that is directed against; In the network that the terminal can be inserted; Confirm to reach the network of setting priority, and in the network of confirming, select a network as second network to service priority said to be carried out.
Confirm to reach the network of setting priority, can wait to carry out the network of service priority ordering to said for confirming in preceding M position to service priority said to be carried out, as; Set M=3; Then can select to business to be carried out, prioritization is at preceding 3 network, and from 3 networks determining; Select a network as second network, be used to carry out business said to be carried out.
Step 103, terminal are inserted and are continued to reside in second network.
The terminal is inserted in second network; And after the business said to be carried out that in second network, is finished; Continue to reside in second network, and need not as prior art, resident network (network of high priority) again when standby accesses terminal; Thereby reduce the number of times that the terminal comes and goes between network, reduce interoperability frequency between network.
More excellent; In order further to reduce the number of times that the terminal comes and goes between network, if said first network is a network resident first behind the starting up of terminal, then the terminal be positioned at first network coverage and terminal before access second network; The terminal continues to reside in first network; And need not as prior art, the network of resident first network insertion high priority after the start, thus interoperability frequency between network can further be reduced.
The terminal is finished in second network after the business said to be carried out; When the signal strength signal intensity of second network does not reach setting intensity; The terminal can be from the network that can insert; Confirm a network, and continue to reside in this network, to support of the smooth execution of this terminal as passive side's business (like called business).
Business to be carried out comprises multinomial when professional at the terminal; Be said multinomial traffic set priority; The preferential network of selecting is carried out the highest business of professional medium priority that is not finished as yet; Repeat the following step, be finished, the network at place, terminal when residing in last business and being finished until all business:
In a plurality of business (business that is not finished as yet) that needs are carried out, select the highest business of priority as terminal business to be carried out,, confirm second network to this business to be carried out;
Determine be used to carry out said wait to carry out second network of professional (the highest business of a plurality of professional medium priority of needs execution) after; Confirm in a plurality of business that needs are carried out in the business except that the highest business of priority the business that can in second network of determining, carry out;
Except that the highest business of priority, utilize second network to carry out the business of determining that can in second network, carry out simultaneously.
Owing to reasons such as constantly moving of terminal, the terminal is in the difference moment, and the network that can insert possibly change, and promptly the terminal in difference constantly maybe be from the coverage of heterogeneous networks.Smooth execution in order to ensure terminal traffic; The terminal is after inserting second network; And before the business said to be carried out that in second network, is finished; The terminal repeats following process, and till the terminal is finished business said to be carried out, and the terminal resides in the said network at place when professional that is finished:
Whether terminal judges is in the coverage of second network, if then continue in second network, to carry out business said to be carried out; Otherwise the terminal is confirmed again from the network that can insert and can be waited to carry out professional network as second network by support terminal, and continues to carry out business said to be carried out.
For example; Carry out in the process of data service (business to be carried out) at LTE network (second network) at the terminal, can constantly judge whether to be in the coverage of LTE network, if; Then continue in the LTE network, to carry out said data service; Otherwise,, confirm not to be in the coverage of LTE network if constantly at T1; The network that the terminal is confirmed to support data service from the network that T1 can insert constantly again is as second network; If the network that T1 can insert at moment terminal is TD-SCDMA network and GSM network, then can confirms TD-SCDMA network (perhaps GSM network) again as second network, and in the TD-SCDMA network of confirming again (second network of confirming again), continue to carry out said data service.And; The terminal is in the process of the said data service of the continuous execution of the TD-SCDMA network trunk of confirming again; Also can constantly judge whether to be in the coverage of TD-SCDMA network; If confirm constantly not to be in the coverage of TD-SCDMA network at T2, then the terminal network from the network that T2 can insert constantly, confirming again to support data service is as second network, and constantly whether duplicate detection is in the coverage of second network of determining again; Be finished until data service, reside in the network that belongs to when being finished said data service.
In order to be directed against business to be carried out; Can keep utilizing the highest network of priority to carry out this business to be carried out as far as possible; Thereby guaranteeing the implementation quality of the business that this is to be carried out, is that the terminal is after inserting second network when carrying out the highest network of the priority of business said to be carried out in the network that can insert of terminal at said second network; And before the business said to be carried out that in second network, is finished; The terminal repeats following process, and till the terminal is finished business said to be carried out, and the terminal resides in the said network at place when professional that is finished:
Whether the terminal is detected the current network that can insert and is changed; When in confirming the current network that can insert, other networks occurring; Other networks are continued to carry out business said to be carried out as second network, and said other networks are the highest networks of priority of carrying out said business in the current network that can insert.
For example, the network that T1 can insert constantly at the terminal has only the GSM network, to data service; Whether the terminal will confirm that the GSM network is the highest network of priority, and carry out in the process of data service in the GSM network at the terminal, can detect the current network that can insert and change; If detect the network that can insert constantly at T2 is TD-SCDMA network and GSM network; Then the TD-SCDMA network will be inserted in the terminal, utilize the TD-SCDMA network to carry out data service, in the TD-SCDMA network, carry out in the process of data service; The detection to the current network that can insert still can constantly be initiated in the terminal; If detecting the network that can insert constantly at T3 is LTE network, TD-SCDMA network and GSM network, then the LTE network will be inserted in the terminal, utilize the LTE network to carry out data service.Certainly; Carry out in the process of data service at the LTE network, also can constantly initiate detection, in case have to data service to the current network that can insert; Priority is higher than other networks of LTE network; To utilize other networks to carry out data service, till data service was finished, the terminal resided in the network that belongs to when being finished data service.
In the method that the embodiment of the invention one provides; Network side can transmit control message to the terminal through air interface; This control messages is used for the method whether control terminal select for use the embodiment of the invention one to provide and realizes that network is resident; The resident method of network that the embodiment of the invention one provides is carried out in the terminal when confirming that according to this control messages the method that can select for use the embodiment of the invention one to provide realizes that network is resident.
Be elaborated through the scheme of two concrete instances below to the embodiment of the invention one.Suppose to exist simultaneously in the communication system LTE network; TD-SCDMA network and GSM network through embodiment two, are a business with business to be carried out respectively; With embodiment three, being a plurality of business with business to be carried out is elaborated to the scheme of the embodiment of the invention one.
Embodiment two,
The embodiment of the invention two provides a kind of network resident method, and then the steps flow chart of this method is as shown in Figure 3, specifically may further comprise the steps:
Access network and resident behind step 201, the starting up of terminal.
The terminal according to the network schemer of self supporting, is searched for, is measured each network after start, selects the best network corresponding district of signal quality to insert this network.After inserting the sub-district, terminal monitoring also reads broadcast, confirms the neighboring BS information of this sub-district.But even the corresponding network in sub-district, place, terminal is not the highest network of priority that defines in the standard agreement, the terminal also resides in this network with continuing, and need not to insert the highest network of priority that defines in the standard agreement.
Suppose that in this step the GSM network is inserted and resides at the terminal.
Whether step 202, terminal judges GSM network support terminal business to be carried out.
In the present embodiment; Wait to carry out professional priority and whether reach the condition enactment of setting priority and be said judging first network: judge that first network waits to carry out professional priority and whether reach the highest said, and be that voice service and data service are that example describes with business to be carried out respectively.
Among the embodiment four below present embodiment reaches; All set: the network priority configuration information to data service is higher than the TD-SCDMA network for the LTE network; And the TD-SCDMA network is higher than the GSM network; Promptly in current communication system, the professional tenability of data putting in order from high to low is LTE network, TD-SCDMA network, GSM network.Network priority configuration information to voice service is higher than the TD-SCDMA network for the GSM network, and promptly in current communication system, the professional tenability of voice putting in order from high to low is GSM network, TD-SCDMA network.
Suppose in this step that terminal business to be carried out is data service:
According to the network priority configuration information of having stored, judge whether the GSM network satisfies predetermined condition to data service.Owing to (comprise the GSM network in the network that the GSM network is not the terminal can be inserted; TD-SCDMA network and LTE network), to data service, (network is not to data service in the network that can insert of terminal to the network that priority is the highest; Prioritization is at preceding 1 network); That is, the GSM network satisfies predetermined condition, continues execution in step 203.
Again, suppose in this step that terminal business to be carried out is a voice service:
According to the network priority configuration information of having stored, judge whether the GSM network satisfies predetermined condition to voice service.Since in the network that the GSM network is the terminal can be inserted (comprising GSM network and TD-SCDMA network), to voice service, the network that priority is the highest; Promptly; The GSM network does not satisfy predetermined condition, then, carries out voice service at the GSM network; And when voice service is finished, continue to reside in the GSM network.
Concrete, the terminal is in the network that the support voice service of determining and terminal can be inserted, and the GSM network that priority is the highest is carried out in the process of voice service; Owing to reasons such as moving of terminal, if the signal strength signal intensity of GSM network does not reach when setting intensity, the terminal will be inserted the TD-SCDMA network and continue to carry out voice service; The terminal is continued to carry out in the process of voice service at the TD-SCDMA network; Can constantly detect and whether can insert the GSM network, and in the time can inserting the GSM network, insert the GSM network again and continue to carry out voice service; And when residing in voice service and being finished, the TD-SCDMA network or the GSM network at place, terminal.
The terminal is after voice service is finished, when residing in voice service and being finished in the process of the TD-SCDMA network at place, terminal or GSM network, if the signal strength signal intensity of TD-SCDMA network or GSM network does not reach when setting intensity; For guarantee the terminal as passive side's business (as; By call business) smooth execution, the terminal can be from the LTE network and GSM network (or TD-SCDMA network) that can insert, according to the definition of standard agreement; Confirm the network that priority satisfies condition; Like condition is that priority is the highest, then can confirm as the LTE network, and continues to reside in this network.
The network of data service is confirmed to be used to carry out in step 203, terminal.
The terminal according to stored to the network priority configuration information of data service, confirm the GSM network that can insert at the terminal, in TD-SCDMA network and the LTE network, to data service, it is the LTE network that priority satisfies the highest network of priority.
The LTE network that is used to carry out data service is inserted at the terminal, after the LTE network is finished data service, continues to reside in the LTE network.
The terminal is in determining the network that can insert at the terminal, and to data service, the LTE network that priority is the highest is carried out in the process of data service; If the signal strength signal intensity of LTE network does not reach when setting intensity, the terminal will continue to select to data service from TD-SCDMA network and GSM network that the terminal can be inserted; The TD-SCDMA network that priority is the highest; Insert the TD-SCDMA network and continue to carry out data service, the terminal continues to carry out in the process of data service at the TD-SCDMA network, can continuous detection whether can insert the LTE network; And in the time can inserting the LTE network; Again insert the LTE network and continue to carry out data service, and when residing in data service and being finished, the TD-SCDMA network or the LTE network at place, terminal.
Certainly, carry out in the process of data service at the LTE network at the terminal, when the signal strength signal intensity of LTE network of network does not reach setting intensity; If the signal strength signal intensity of TD-SCDMA network does not reach setting intensity yet, the terminal will be inserted the GSM network and continue to carry out data service, and the terminal can constantly detect whether to insert TD-SCDMA network or LTE network; If can insert the LTE network, will preferentially insert the LTE network and continue to carry out data service, otherwise; When the signal strength signal intensity of TD-SCDMA network reaches setting intensity, will insert the TD-SCDMA network and continue to carry out data service, and constantly whether monitoring can insert the LTE network; In case can insert the LTE network; Insert the LTE network at once and continue to carry out data service, and when residing in data service and being finished, GSM network, TD-SCDMA network or the LTE network at place, terminal.
The terminal is after data service is finished; The network at place, terminal when residing in data service and being finished; If the signal strength signal intensity of this network does not reach when setting intensity, the terminal also can be from the network that can insert, according to the definition of standard agreement; Confirm the network that priority is the highest, and continue to reside in this network.
When step 203 is confirmed to be used to carry out the network of data service; If the LTE network can't be inserted in this moment terminal; Determine GSM network that then can insert from the terminal and the TD-SCDMA network to data service, the network that priority is the highest is the TD-SCDMA network.
Then in step 204, insert the TD-SCDMA network and be used to carry out data service; And in the process of carrying out data service; Constantly whether detection can insert the LTE network, if can insert the LTE network, will insert the LTE network and continue to carry out data service; And when residing in data service and being finished, the network at place, terminal.
Embodiment three,
The embodiment of the invention three provides a kind of network resident method, and then the steps flow chart of this method is as shown in Figure 4, specifically may further comprise the steps:
Access network and resident behind step 301, the starting up of terminal.
Suppose that in this step the TD-SCDMA network is inserted and resides at the terminal.
The multinomial professional priority of waiting to carry out is confirmed at step 302, terminal.
When the business that carry out at needs at the terminal is multinomial, can be according to the multinomial significance level of waiting to carry out business, perhaps other factors are confirmed the multinomial professional priority of waiting to carry out.
As, when business to be carried out is voice service and data service, can require to set priority according to the real-time of business.Because voice service is had relatively high expectations to real-time, need the preferential execution that ensures voice service, therefore voice service is set to high priority, and data service is set to low priority.In the present embodiment, be voice service and data service with multinomial business to be carried out, and voice service is set to high priority, it is that example describes that data service is set to low priority.
Whether step 303, terminal judges TD-SCDMA network support voice service.
In the present embodiment, with judging that first network waits to carry out professional priority and whether reach the condition enactment of setting priority and be said: judge that first network waits to carry out professional priority and whether reach the highest said.
According to the network priority configuration information of having stored to voice service, whether terminal judges TD-SCDMA network supports the highest voice service of professional medium priority multinomial to be carried out, and judges promptly whether the TD-SCDMA network satisfies predetermined condition.Since in the network that the TD-SCDMA network is not said voice service of support and terminal can be inserted (comprising GSM network and TD-SCDMA network), to voice service, the network that priority is the highest; Promptly; The TD-SCDMA network does not satisfy predetermined condition, then, continues execution in step 304.
The network of the highest voice service of execution priority is confirmed to be used in step 304, terminal.
In this step, the terminal is determined to voice service from the GSM network and TD-SCDMA network that can insert, and the network that priority is the highest is the GSM network.
The GSM network is inserted at step 305, terminal.
The terminal is inserted the GSM network and is carried out voice service, and can judge whether the GSM network supports the parallel processing of voice service and data service: when definite GSM network can be supported the parallel processing of voice service and data service, carry out voice service and data service simultaneously; And when voice service is finished; Detect data service and whether be finished,, will reside in the GSM network if data service is finished; Otherwise, execution in step 306; When definite GSM network is not supported the parallel processing of voice service and data service, after voice service is finished, execution in step 306.
The network of data service is confirmed to be used to carry out in step 306, terminal.
The method of network of confirming to be used to carry out data service (the highest business of professional medium priority that is not finished as yet) is identical with the method for the network of confirming to be used to carry out voice service, repeats no more at this.
