Application scenarios of the present invention is below described.
Shown in accompanying drawing 8, this flow process of dispatching method that realizes described neighbor cell task is following:
The first kind is the task of known adjacent district observation time difference, is called Case1.Case1 is applicable to the situation of obtaining synchronizing information.For example adjacent sub-district is assessed through measuring, and signal quality is good, and perhaps adjacent sub-district is through synchronous, and the terminal can find the corresponding observed time difference in adjacent sub-district in adjacent district observation time difference the results list; In this task type, the fine tune of sync bit only need be carried out in the terminal.As, adjacent system information of subdistricts can be directly read at the terminal, has omitted and has carried out again the time that cell search process is come synchronous adjacent sub-district.
Second type is the task of unknown adjacent district observation time difference, is called Case2.Among the Case2, adjacent sub-district is clear and definite, but needs synchronous adjacent sub-district, on adjacent sub-district, need carry out synchronous adjustment by a relatively large margin this moment.
The 3rd type is to need not the task of adjustment synchronously, is called Case3.Case3 is applicable to and obtains the process that scans frequency in the network PLMN information process, detects frequency intensity that this generic task need not adjusted synchronously.
The terminal synchronizes position deviation is designated as TBU, the skew that the current sync bit of GC group connector is synchronous with respect to Serving cell.Under the synchronous situation of terminal and Serving cell, TBU (initially) equals 0.The sync bit adjusted value is designated as TBUadjust, and GC group connector is the sync bit adjusting range of carrying out synchronously that reaches with adjacent sub-district.Wherein, initial synchronisation position adjusted value is designated as TBUadjust_0, and representative gets into the needed adjusted value in adjacent sub-district from Serving cell; Adjusted value performed on adjacent sub-district is designated as TBUadjust_i.Local service sub-district, terminal frame number is designated as LocalSFN, and is resident down at Serving cell, and through after the reception of system information, LocalSFN is consistent with the network service district System Frame Number, thereby supports the scheduling decoding of paging and system information.
For Case1, initial synchronisation position adjusted value (TBUadjust_0) equals the adjacent district observation time difference (OTDneighbor-cell).That is TBUadjust_0=OTDneighbor-cell; That is to say,,, obtain the sync bit adjusted value that gets into adjacent sub-district through searching adjacent district observation time difference the results list for the task of known adjacent district observation time difference.When the terminal got into the adjacent sub-district of known observed time difference, the sync bit adjusted value was the observed time difference of adjacent sub-district; Can be directly through the sync bit adjustment reach with adjacent sub-district synchronously, thereby can begin the processing such as reception of system information fast.
For Case2 and Case3, initial synchronisation position adjusted value equals 0, means when getting into neighbor cell task, need not carry out the adjustment of terminal synchronizes position.That is TBUadjust_0=0; That is to say that for the task of the adjacent district observation of the unknown time difference with for need not the task of adjustment synchronously, the sync bit adjusted value that gets into adjacent sub-district is 0.
Step 83, according to the sync bit adjusted value, terminal synchronizes to adjacent sub-district, and safeguard local frame number.After neighbor cell task triggered, neighbor cell task was dispatched in the terminal in the free time of Serving cell task section.The sync bit adjusted value adjustment sync bit that the terminal was obtained according to a last step, reach with adjacent sub-district synchronously, thereby can begin neighbor cell task.At this moment, need to upgrade terminal synchronizes position deviation TBU:
TBU＝TBUadjust_0；
Simultaneously, the terminal is safeguarded local service sub-district frame number to the process of adjacent sub-district according to the sync bit adjusted value is synchronous, is made local service sub-district frame number consistent with the Serving cell frame number.Fig. 9 is the sketch map of adjustment synchronously when shifting between Serving cell and the adjacent sub-district in the application scenarios of dispatching method of neighbor cell task shown in Figure 8.As shown in Figure 9, can safeguard the sub-district frame number according to the long cycle of subframe, that is, in the cycle of a sub-frame length of every mistake, the Serving cell frame number of terminal local record is added 1 operation.If adjustment causes the terminal to miss the statistics of a system-frame like the figure sync bit, need add 1 operation to the Serving cell frame number of local record, make the Serving cell frame number of terminal local record consistent with the Serving cell System Frame Number.
And; Safeguard that local service sub-district frame number is consistent with the Serving cell System Frame Number; If the sync bit adjustment causes the terminal to miss the statistics of a system-frame; Need add 1 operation to the Serving cell frame number of local record, make the Serving cell frame number of terminal local record consistent with the Serving cell System Frame Number.
In addition, for Case2, the terminal can be behind the adjacent sub-district of synchronous unknown observed time difference, and the observed time difference of adjacent sub-district is measured and stored to execution in step 61, realizes the parallel scheduling of neighbor cell task and service cell task, simplifies the neighbor cell task process.
Step 85, in the time of need returning Serving cell, according to the terminal synchronizes deviation of upgrading, terminal synchronizes is to Serving cell.That is to say, finish that in the time of perhaps need returning Serving cell paging receiving or system information, the adjustment of reverse sync position is carried out according to the synchronism deviation TBU that is write down in the terminal, returns Serving cell at neighbor cell task.
Return sync bit adjusted value=subframe lengths-TBU;
And; As shown in Figure 9; Safeguard that local service sub-district frame number is consistent with the Serving cell System Frame Number; If the sync bit adjustment causes the terminal to miss the statistics of a system-frame, need add 1 operation to the Serving cell frame number of local record, make the Serving cell frame number of terminal local record consistent with the Serving cell System Frame Number.
Additionally, after execution in step 85 was returned Serving cell, execution in step 81 once more, made the parallel scheduling of Serving cell task and neighbor cell task.
The present invention has following effect:
1) based on Serving cell synchronously, safeguard the synchronized relation of a plurality of adjacent sub-districts, through the adjustment of terminal synchronizes position can conveniently realize to adjacent sub-district synchronously, the quick redirect in the minizone of known synchronized relation;
2) terminal is synchronized to adjacent sub-district fast through sync bit adjustment, can save the independent adjacent cell synchronizing time, can directly receive adjacent domain system information, simplifies district reselecting and obtains adjacent sub-district process such as PLMN information;
3) neighbor cell task scheduling is based on that Serving cell realizes with service cell task dispatching priority synchronously; Be equal to the normal residence time that has increased the terminal; Avoided adjacent sub-district process the influence of service to be provided, improved terminal originating service and call successful rate the terminal;
4) take into full account Serving cell task gap, realize the integrated dispatch of neighbor cell task and service cell task, reduce the terminal overall work time, improve power saving performance.
The further application of the invention scene is below described.The present invention provides the method for the neighbor cell task scheduling on a kind of TDSCDMA Serving cell synchronous foundation, comprising:
Step 3, according to the sync bit adjusted value, terminal synchronizes to adjacent sub-district, and safeguard local frame number;
Step 4 during neighbor cell task, is upgraded the terminal synchronizes position deviation, and is safeguarded local frame number;
Step 5, in the time of need returning Serving cell, according to the terminal synchronizes deviation, terminal synchronizes is to Serving cell, and safeguards local frame number.
Wherein, after neighbor cell task triggered, neighbor cell task was dispatched in the terminal in the free time of Serving cell task section.In this section, the task of completion comprises that synchronous adjustment gets into that carry out adjacent sub-district, neighbor cell task, Serving cell is returned in adjustment synchronously free time.
In the prior art, when carrying out neighbor cell task, the terminal can lose the synchronous of Serving cell is in the Cell searching state, upgrades thereby can not monitor the Serving cell paging and carry out system information, causes initiating the professional incoming call that perhaps misses.And among the present invention, the TD-SCDMA system is synchronous.Based on this system features, the synchronized relation of a plurality of minizones can be kept in the terminal.Utilize the synchronous difference in minizone, the terminal can be on the Serving cell synchronous foundation, and the process sync bit is adjusted and reached adjacent cell synchronizing.Wherein, the terminal comprises frame synchronization synchronously to the sub-district, as far as Serving cell also comprise System Frame Number synchronously.Based on this synchronous, can support the correct reception of cell system information.Based on the consideration to the terminal power saving performance, the reception activity of paging information is discontinuous, so just forms the free time section of Serving cell task.When carrying out the adjacent domain system message pick-up or obtaining network PLMN information, in order not influence the reception of Serving cell paging information, the terminal can utilize the free time section of Serving cell task.Utilize the terminal to safeguard multiple sectors at same step relation; Realize the synchronous Target cell of change flexibly; Can go up the scheduling of optimizing Serving cell task and neighbor cell task largely; Improve the terminal power saving performance, also improved the actual residence time at terminal, reduction can not be initiated the professional probability that perhaps misses incoming call.
