Embodiment
For making the object of the invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, scheme according to the invention is done to specify further.
Core concept of the present invention is: portable terminal counts self terminal traffic attribute and setting terminal service attribute parameter (UE voice usage setting) according to self business characteristic.When portable terminal is accomplished circuit domain business in 2G or 3G network after, confirm standby in which network according to the terminal traffic attribute.Making with the speech business to be that main user priority is set up speech business in 2G or 3G network, is that main user enjoys the service of two-forty and big bandwidth at the LTE network with the data service, uses professional impression thereby improved the user greatly.
Portable terminal of the present invention is bimodulus or the multimode terminal with TD-LTE and 2G/3G access capability, but when using LTE to insert, can't the sending and receiving circuit domain business, singly treat hand-held digital mobile terminal like multimode.
Referring to Fig. 1, Fig. 1 is a mobile terminal network system of selection flow chart in the embodiment of the invention.Concrete steps are:
When step 101, portable terminal receive circuit domain business at the LTE network, fall back to 2G or 3G network and accomplish this circuit domain business.
2G in this step or 3G network both can be accomplished circuit domain business through circuit domain, also can handle the data service that the LTE network is being handled through packet network.Wherein, circuit domain business comprises callings such as initiating voice, video telephone, and receives pagings such as voice, video telephone.
In this step, if do not receive data service always, then standby in 2G or 3G network always if receive data service, is directly transferred to the LTE network and is accomplished the data service of receiving.
Receive circuit domain business if be in the portable terminal of LTE network, when falling back to 2G or 3G network, in the LTE networking, when there was ongoing data service in this portable terminal, this data service was also accomplished in 2G that falls back to or 3G network.If the circuit domain business in 2G or the 3G network is accomplished, but the data service in this 2G or 3G network also imperfect tense, before the LTE network is transferred in decision, needs this data service is accomplished, and then transfer in the LTE network.Certainly,, directly in this 2G or 3G network, accomplish this data service, when portable terminal need carry out new data service, transfer to the LTE network again if this moment, portable terminal was confirmed is standby in 2G or 3G network.Handle the data service of in 2G or 3G network, carrying out in the embodiment of the invention like this, purpose is to improve the user to use professional impression, in order to avoid same business frequent switching in heterogeneous networks carries out.
The terminal traffic attribute UE voice usage setting that portable terminal obtains in the step 102 is that portable terminal is added up according to the own service characteristics.Referring to Fig. 2, Fig. 2 is a mobile terminal to update own service attribute flow chart in the specific embodiment of the invention.Concrete steps are:
Step 201, portable terminal is in the predetermined period circuit domain business that then statistics is carried out self in the Preset Time window and the quantity of data service.
Preset Time window in this step is the value that is provided with in advance, and this value is much bigger with respect to a data business of execution or time value that circuit domain business spent.Such as being set to 48 hours or 96 hours etc., purpose is not frequent transfer between two networks, makes the user enjoy better professional impression.
The quantity of circuit domain business be this portable terminal 3G the summation of quantity of the circuit domain business accomplished of network; The quantity of data service for this portable terminal 3G the summation of quantity of the data service accomplished in network and the LTE network.
Predetermined period in this step can be set according to practical application, even can the preset time window unanimity.Suppose that predetermined period is 48 hours, then portable terminal is every at a distance from 48 hours statistics each number of services once, and the Preset Time window scope of statistics can be perhaps each professional quantity summation in 96 hours of statistics before constantly 48 hours.
Whether step 202, the professional quantity in portable terminal decision circuitry territory less than data field professional quantity and default bias amount sum, if, execution in step 203; Otherwise, execution in step 204.
Confirm N in this step
Cs＜N
DataWhether+offset sets up, wherein, and N
CsBe the quantity of circuit domain business, N
DataBe the quantity of data service, offset is the default bias amount, and this value is confirmed according to operator's operation policy-flexible.
Based on above-mentioned same inventive concept, the invention allows for a kind of network selecting portable terminal based on the circuit domain dropping technology.Referring to Fig. 3, Fig. 3 is the mobile terminal structure sketch map of network selecting in the specific embodiment of the invention.This portable terminal comprises: receive to initiate unit 301, first processing unit 302, acquiring unit 303 and second processing unit 304.
Receive and initiate unit 301, be used for receiving or initiate circuit domain business at Long Term Evolution LTE network.
Acquiring unit 303, when being used for first processing unit 302 and accomplishing said circuit domain business, the terminal traffic attribute user speech usage of obtaining the portable terminal at self place is provided with UE voice usage setting.
Preferably, this portable terminal further comprises: confirm unit 305.
Confirm unit 305, be used in predetermined period is then added up the Preset Time window the circuit domain business that self place portable terminal carries out and the quantity of data service; Whether the quantity of confirming circuit domain business less than data field professional quantity and default bias amount sum, if self terminal traffic attribute UE voice usage setting is updated to data centric; Otherwise, self terminal traffic attribute is updated to voice centric.
Acquiring unit 303 is used for from confirming that unit 305 obtains the terminal traffic attribute UE voice usage setting of the portable terminal that self belongs to.
Preferably,
Receive to initiate unit 301, the portable terminal that is further used for self place during standby, receives data service in 2G or 3G network.
Preferably,
The unit of the foregoing description can be integrated in one, and also can separate deployment; A unit can be merged into, also a plurality of subelements can be further split into.
In sum, portable terminal receives circuit domain business at the LTE network, falls back to accomplish after this circuit domain business in 2G or the 3G network; The service attribute of portable terminal identification terminal; If portable terminal is to be main (voice centric) with the speech business, then preferentially reside in 2G or 3G network, if the user is main (data centric) with the data service; Then transfer to the LTE network; Like this, portable terminal just can use circuit domain business at circuit domain business performance good 2G or 3G network, and the LTE network good in the data service performance uses packet switch domain service.Pass through said method; Make with the speech business to be that main user priority is set up speech business at 2G, 3G network; Improved the success rate that receives and initiate paging; With the data service is that main user priority uses Packet Service at the LTE network, enjoys the service of LTE two-forty and big bandwidth, improves the user greatly and uses professional impression.
If after the completion circuit domain business, and confirm to transfer to before the LTE network, have uncompleted data service, use professional impression, need in 2G or 3G network, accomplish this data service and transfer to the LTE network again in order to improve the user.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
