Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
A kind of standard changing method is provided in the present embodiment, and Fig. 1 is the flow chart according to the standard changing method of the embodiment of the invention, and as shown in Figure 1, this method comprises:
Step S102, whether the data bandwidth that detecting the current standard network of living in of multimode terminal provides satisfies the required data bandwidth of current data service, and wherein, above-mentioned multimode terminal is for supporting the terminal of multiple standard;
Step S104, the data bandwidth that provides at the current standard network of living in of multimode terminal does not satisfy under the situation of the required data bandwidth of current data service, and this multimode terminal is switched to the standard that has higher data bandwidth than current place standard by current place standard.
Present embodiment passes through above-mentioned steps, when the data bandwidth that detects the current standard network of living in of multimode terminal and provide does not satisfy the required data bandwidth of current data service, this multimode terminal is switched to the standard with higher data bandwidth by current place standard, thereby can determine whether to carry out standard according to the data bandwidth of multimode terminal demand switches, and in the prior art by the judgement of signal quality being carried out the switching between different systems, still can't satisfy the situation of user data service demand in the time of current standard network conforms demanding terminal of living in can occurring, and carry out switching between different systems by the judgement of whether the data bandwidth being satisfied the terminal traffic demand in the present embodiment, solved that UE current demand signal quality meets the requirements but still the problem that can't satisfy the demand of user data service, thereby satisfied the demand of user data service effectively, improved user's experience.
In the specific implementation, the mode whether data bandwidth that detecting the current standard network of living in of multimode terminal provides satisfies the required data bandwidth of current data service has a variety of, a kind of preferred implementation is provided in the present embodiment, this mode detects according to the data volume of the data service that sends from terminal, concrete mode can for: whether the data volume that detects the data buffer zone of multimode terminal surpasses predetermined threshold value, data volume in the data buffer zone surpasses under the situation of threshold value, determines that the data bandwidth that the current standard network of living in of multimode terminal provides does not satisfy the required data bandwidth of current data service.Wherein, above-mentioned data buffer zone is used for buffer memory from the data of the data service of multimode terminal transmission, for example, and under the GSM standard, above-mentioned data buffer zone is that subnet is assembled convergence protocol (SubNetwork Dependent Convergence Protocol abbreviates SNDCP as) data buffer zone; Under the TD standard, above-mentioned data buffer zone is packet data convergence protocol (Packet Data Convergence Protocol abbreviates PDCP as) data buffer zone.This mode is easy to implement, and realizability is strong.
Consider that the user wishes that usually the data bandwidth that uses is bigger, for all promising policy user's request as far as possible, shorten switching time, improving the user experiences, when multimode terminal is switched to the standard that has higher data bandwidth than current place standard by current place standard, can search for whole standards that multimode terminal can switch by searching the net module; In the standard that can switch that searches, preferentially select the highest standard of data bandwidth to switch.For example, be under the GSM standard when the user is current, when needing to switch, can switch to TD standard and LTE standard by searching the net block search, at this moment, because the LTE data bandwidth is higher than the TD standard, therefore the preferential LTE standard of selecting is switched, behind LTE standard handoff failure, reattempt to the TD standard and switch.
But because under some situation, the higher standard of data bandwidth might (for example not supported the user's voice business, the LTE standard), and when the user need use speech business, this moment is if the current data flow is less, current bandwidth is enough to satisfy, then continue to reside in current standard and needn't be to (for example having more the standard of high bandwidth, LTE) switch, like this, when the user initiates voice again, just needn't under the LTE standard, switch to TD by CSFB (Circuit Switched Fallback) or GSM does speech business, reduce switching times.And if current standard can not satisfy the required data bandwidth of user, then can be when multimode terminal be switched to the standard that has higher data bandwidth than current place standard by current place standard, judge at first that multimode terminal is current whether to use speech business; Being judged as under the situation not, again multimode terminal is switched to the standard that has higher data bandwidth than current place standard by current place standard.In this way, avoided causing the user to interrupt speech business because standard is switched, thereby guaranteed quality of service.
Consider with multimode terminal by current place standard after the standard that has higher data bandwidth than current place standard is switched, be might handoff failure, at this moment, according to related protocol, terminal might attempt switching always, thereby influences the use of other business on the terminal.Therefore, preferably, can carry out under the situation of handoff failure than the standard that current place standard has higher data bandwidth to all, first scheduled duration is set, when surpassing first scheduled duration, multimode terminal is switched to the standard that has higher data bandwidth than current place standard by current place standard again.
And when repeatedly still not having handover success above first scheduled duration, may show that active user's condition of living in is difficult to carry out corresponding switching, at this moment, carry out the standard switching to the influence of other business of terminal in order further to reduce, can also subtend all standards that have a higher data bandwidth than current place standard situation of carrying out handoff failure count, reach in count value under the situation of predetermined value, second scheduled duration is set, when surpassing second scheduled duration, multimode terminal is switched to the standard that has higher data bandwidth than current place standard by current place standard again, wherein, second scheduled duration is greater than first scheduled duration.In this way, switch repeatedly surpassing first scheduled duration still under the unsuccessful situation, the second longer scheduled duration can be set, to switching again constantly, saved system resource in second scheduled duration, improve user's experience.
For example, it is 5 minutes that the initial duration of data service switching timer is set, and data service toggle count device initial value is set is 0.When UE resides on the GSM, when if the SNDCP data buffer zone is full, send the full Indication message in data field to searching the net module, search the net module at first attempt carrying out to the LTE standard resident, if resident not going up, carry out resident toward TD again, if still resident not going up proves current no LTE or TD available cell, then get back to the GSM standard, and the professional switching timer of log-on data, timer duration is made as 5 minutes (first scheduled duration), attempts counter and counts (for example, Counter Value increases 1), when the timer run duration, do not reattempt. behind the timer expiry, attempt again, if unsuccessful again, then start timer again, counter increases 1; If the number of times (for example, 5 times) of predetermined value is all unsuccessful continuously, then start timer, timer duration is 1 hour (second scheduled duration), Counter Value replacement (herein for putting 0); After switching on other standards, stop timer and with counter reset (herein for putting 0).
When UE resides in TD and goes up, if when the PDCP data buffer zone is full, send the full Indication message in data field to searching the net module.Search the net module and at first attempt carrying out to the LTE standard resident, if resident not going up, prove current no LTE available cell, then get back to the TD standard, and the professional switching timer of log-on data, timer duration is made as 5 minutes (first scheduled duration), attempt counter and count (for example, Counter Value increases 1), when the timer run duration, do not reattempt, behind the timer expiry, attempt again, if unsuccessful again, then start timer again, counter increases 1; If the number of times (for example, 5 times) of predetermined value is all unsuccessful continuously, then start timer, timer duration is 1 hour (second scheduled duration), Counter Value replacement (herein for putting 0); After switching on other standards, stop timer and with counter reset (herein for putting 0).
