Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of the invention provides the method for a kind of terminal bearing data service, and the method for present embodiment is the performed method of single deck tape-recorder double-standby terminal, and flow chart comprises as shown in Figure 1:
There are two network processing units at the terminal that is appreciated that the embodiment of the invention, is used for the business of processing terminal in two networks respectively.The terminal is after start; Only open first network processing unit, reside in first network, carry out the carrying of speech business by the CS territory of first network processing unit with the terminal; Here first network is meant that voice signal covers more network, and resident being meant here is attached to first network with the terminal; And for the PS territory at terminal, can reside in first network by the PS territory of first network processing unit with the terminal, also can not reside in any network.
With the existing mobile communication network is the example explanation, and first network processing unit can reside in the CS territory at terminal in the 2G network, particularly, first network processing unit initiation location area updating (Location Area Update, LAU) process is attached to the 2G network; Alternatively; First network processing unit can also reside in the PS territory at terminal in the 2G network; Particularly, (General Packet Radio Service, attachment flow GPRS) is attached to the 2G network with the PS territory to first network processing unit initiation general packet radio service technology.
The user can initiate the data service of PS through the terminal; Then second network processing unit can be opened in the terminal; Such as the operations such as transmit receive antenna that are ready to second network; Detect the signal of second network by second network processing unit; Particularly; Can detect receive signal from second network property parameters whether in the scope that presets, if confirm that the terminal can detect the signal of second network.For example: (whether Received Signal Strength Indication RSSI) can be greater than certain value, or (whether Signal to Noise Ratio SNR) can be greater than certain value etc. to receive the signal to noise ratio of signal in the signal strength signal intensity indication that detect to receive; Second network processing unit can also be through other method detection signal.
Need to prove that if the data service of the PS that initiate at the terminal need be carried, then second network processing unit need be closed in the terminal, by first network processing unit this data service is handled in first network.Then if the PS territory at terminal has resided in first network at this moment, then when setting up the professional connection of packet-switched data, first network processing unit can directly carry out the data establishment of connection; If this moment, the PS territory at terminal did not reside in any network, then first network processing unit in setting up the process that data service connects, earlier that the PS territory is resident in first network.
At this moment; The data service of the PS that initiate at the terminal need be carried in second network; Then (GPRS Attach) flow process and protocol data bag (Packet Data Protocol need be adhered to through second network processing unit initiation GPRS in the terminal; PDP) context active flow (context Activate Procedure); Thereby the data service of setting up PS connects, and so just can come bearing data service through second network.If before second network carrying data service, the PS territory at terminal has resided in first network, then need withdraw from PS territory resident at first network earlier, particularly, can initiate the attachment removal flow process through GPRS by first network processing unit.
Be appreciated that; The professional connection gets nowhere if second network processing unit is set up packet-switched data in second network; Then in first network, set up the professional connection of packet-switched data, and pass through the data service of first network carrying PS by first network processing unit.
It is thus clear that; In the embodiment of the invention; The single deck tape-recorder double-standby terminal is when start; Only the CS territory with the terminal resides in first network; When the data service of PS is initiated; If the terminal detects the signal of second network, then just in second network, set up the professional connection of packet-switched data, and pass through the data service of second network carrying PS.Make the single deck tape-recorder double-standby terminal when not initiating data service, only be operated under a kind of network schemer; And initiate when there is data service at the terminal; And the running of just opening another kind of network schemer in the time of detecting the signal of second network has reduced the power consumption of single deck tape-recorder double-standby terminal to a certain extent.
Be appreciated that; In a concrete embodiment, if first network processing unit at terminal is after carrying out above-mentioned steps 103, promptly after the data service end through first network carrying PS; Can withdraw from PS territory resident at first network, also can continue the PS territory is resided in first network.
Particularly; If first network processing unit withdraws from the PS territory when first network resident; Can initiate GPRS attachment removal flow process (GPRS Deattach Procedure), perhaps initiate context deexcitation flow process (PDP context Deactivate Procedure) and the GPRS attachment removal flow process of PDP.Make the terminal only when the data service of initiating PS like this, just the PS territory is resided in the network, reduced the power consumption at terminal further.
Be appreciated that when first network processing unit can finish in the data service of PS, confirm the concluding time of the data service of PS earlier,, just initiate the PS territory is withdrawed from the resident flow process of first network if the concluding time surpasses preset time; If when the process ends of the data service of PS did not surpass preset time, the data service of new PS was initiated at the terminal again, then can be through the current resident new PS data service of first networking carrying in terminal;
After new PS data service finishes, in preset time, there is not the PS data service of renewal if confirm the concluding time of new PS data service, just initiate the PS territory is withdrawed from the resident flow process of first network.
Particularly, first network processing unit starts a timer, if timer expiry then initiates the PS territory is withdrawed from the resident flow process at first networking after can finishing in the data service of PS; If there is new PS data service at timer terminal when not overtime, then, restart timer through after the new PS data service of current resident first network carrying in terminal, carry out the circulation of a new round again.
In another concrete embodiment, if second network processing unit at terminal after carrying out above-mentioned steps 104, after promptly the data service through second network carrying PS finishes, can withdraw from PS territory resident at second network.
The PS territory that is appreciated that the terminal can the PS territory be resided in first network by first network processing unit at terminal, and the PS territory at terminal also can reside in any network after withdrawing from resident in second network.
Need to prove, when second network processing unit can finish in the data service of PS, confirm the concluding time of the data service of PS earlier,, just initiate the PS territory is withdrawed from the resident flow process of second network if the concluding time surpasses preset time; If when the process ends of the data service of PS did not surpass preset time, new PS data service was initiated at the terminal again, then can be through the current resident new PS data service of second networking carrying in terminal;
After the data service of new PS finishes, confirm the concluding time of new PS data service, if in preset time, there is not the PS data service of renewal, just initiate the PS territory is withdrawed from the resident flow process of second network.
Particularly, second network processing unit starts a timer, if timer expiry then initiates the PS territory is withdrawed from the resident flow process at second networking after can finishing in the data service of PS; If there is new PS data service at timer terminal when not overtime, then, restart timer through after the new PS data service of current resident second network carrying in terminal, carry out the circulation of a new round again.
Be appreciated that; After having carried out above-mentioned steps 104; When second network processing unit is lower than the threshold value that presets at the signal quality information of confirming second network; Just withdraw from PS territory resident in second network; In this case; When terminal data service is relatively frequent, reduced second network in frequent initiation PS territory resident with withdraw from the complexity of resident flow process, thereby further reduced the power consumption at terminal.
Here signal quality information is meant the power that is used for representing network signal, or coverage rate, or the information such as service quality of signal.
Need to prove, be applied in the foregoing description in the mobile communication system that first network can be the 2G network, second network can be 3G or 4G network; Perhaps first network is a 3G network, and second network is the 4G network.

301, behind the starting up of terminal, only open first network processing unit, initiate the LAU flow process by first network processing unit CS territory at terminal is attached to the 2G network, carry out the carrying of speech business; And the PS territory does not reside in any one network.
302, when the user initiated the data service of PS through the terminal, second network processing unit was opened at the terminal; Do not detect the signal of 3G network if confirm second network processing unit; Then execution in step 305, if detect the signal of 3G network, then execution in step 303.
303, second network processing unit at terminal is initiated the context active flow of GPRS attachment flow, PDP, in 3G network, sets up after data service connects the data service of preferentially carrying PS through 3G network.
304; After the data service of PS finishes; Timer of starting terminal; Behind timer expiry; Second network processing unit is initiated GPRS attachment removal flow process, and perhaps the deexcitation flow process of PDP Context and GPRS attachment removal flow process are closed second network processing unit then; And return step 302, wait for that the data service of PS is initiated next time.
305, second network processing unit is closed at the terminal, in the 2G network, is set up after data service connects the data service of preferentially carrying PS through the 2G network by first network processing unit; And after the data service of PS finished, the starting terminal timer waited behind the timer expiry and the PS territory at terminal to be withdrawed from resident at the 2G network, and returns step 302, waits for that the data service of PS is initiated next time.
Present embodiment and embodiment one and twos' difference is when the data service that does not have PS; The PS territory at terminal does not reside in any network; Make when data service is fewer, reduced the signaling processes such as periodic location update after the residing network of terminal, further reduced the power consumption at terminal.
