Description

A kind of method for searching network of portable terminal
Technical field
The invention belongs to wireless communication technology field, specifically, relate to a kind of method for searching network of portable terminal.
Background technology
Power conservation techniques is a key technology of mobile terminal design, and the stand-by time of portable terminal is to weigh the key index of its performance.Research has started very early and has obtained phasic results at the power conservation techniques of portable terminal.Yet these power conservation techniques are all realized having under the network signal coverage condition.Portable terminal is after breaking away from network's coverage area, meeting is search network ceaselessly, and the method for searching network that uses is searched net as full frequency band, and the battery that causes terminal is approach exhaustion soon, makes portable terminal be far smaller than normal stand-by time under the network condition in the stand-by time under the no network condition.Particularly for TD SDMA (TD-SCDMA) system, because it is in the early stage of development, longer following period of time afterwards, the TD-SCDMA network signal must be the part key area in a city, cover part even part city, the energy consumption height that causes the TD-SCDMA terminal, stand-by time is short, has influence on the commercial process of TD-SCDMA.
Thereby how portable terminal reduces its electrical source consumption after losing network, just becomes the technical problem that needs to be resolved hurrily to improve stand-by time.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method for searching network of portable terminal, and portable terminal is when losing network in the solution prior art, and power consumption is big, the problem of stand-by time weak point.
For addressing the above problem, it is as follows to the invention provides scheme:
A kind of method for searching network of portable terminal comprises:
What the net cycle of searching of portable terminal is set and uses that this searches the net cycle searches the net number of times;
After portable terminal loses network, carry out web search according to net cycle of searching that is provided with and the corresponding net number of times of searching.
Preferably, the set net cycle of searching searches the increase of net number of times along with accumulative total and increases progressively, and uses this net number of times of searching of searching the net cycle to successively decrease along with the increase of searching the net cycle.
Further, maximum adjacent sub-district is set and searches the net cycle; Search net during the cycle smaller or equal to the adjacent sub-district of maximum searching the net cycle, the web search that portable terminal carried out is that net is searched in adjacent sub-district.Search net during the cycle greater than the adjacent sub-district of maximum searching the net cycle, the web search that portable terminal carried out is that full frequency band is searched the combination that net is searched in net and adjacent sub-district.
Preferably, when portable terminal is subjected to effective external trigger, carries out a full frequency band immediately and search network process.
Described effective external trigger is: at preceding special time after once searching net beginning to the suffered external trigger first of portable terminal between the special time of searching before net begins next time; Described external trigger comprises button, renovates, slip lid.
Further, be provided with and wantonly search for most the net cycle, describedly search the net cycle and be increased to this and wantonly search for all after dates of net most and remain unchanged.
Further, portable terminal is before losing network, and the discontinuous reception DRX period and the Page Indication Channel PICH that obtain current network retransmit number of times; The set net cycle of wantonly searching for most is long-pending smaller or equal to described DRX cycle and described PICH repeating transmission number of times.
Preferably, described portable terminal is a TD SDMA TD-SCDMA terminal.
Compared with prior art, in the method for the invention, after portable terminal loses network, intermittently carry out web search.Further, the increase of searching the net number of times according to accumulative total increases searches the net cycle, and reduce use that this searches the net cycle search the net number of times, and dynamically dispatch full frequency band and search net and search two kinds of different method for searching network of net with adjacent sub-district.Both can be so that had under the network condition, portable terminal can search network rapidly in the moment that loses network, can reduce the web search frequency of portable terminal under the situation of no network again, effectively reduce the electrical source consumption of portable terminal, improve the stand-by time of portable terminal.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, describe the present invention below in conjunction with the accompanying drawings and the specific embodiments.
When portable terminal entered no network area, it can't reside on the proper cell (at this moment, portable terminal loses network).According to prior art, carry out to the portable terminal continuity web search, up to find one can be resident the sub-district till.But angle from power saving, under the situation of no network, search not only power consumption but also there is no need of net continuously, so, in the method for searching network of the described portable terminal of the embodiment of the invention, portable terminal intermittently carries out network and searches net, and, search the time interval (the searching the net cycle) T of net in order to save power supply further CycleAlso dynamically adjust.
Please refer to Fig. 1, portable terminal under no network condition, intermittence search net average standby current I StandbyDepend on no longer fully and on average search the net electric current I Search net, and depend primarily on following three factors: the average current I during sleep Sleep, after the periodic wakeup again search network on average search the net electric current I Search net, the duration T of searching net after waking up Search netAccount for the whole net period T of searching CycleRatio, I StandbySpecific as follows:
Figure C200710064374D00051
Usually, I SleepWith respect to I Search netVery little, T Search netWith respect to T CycleAlso very little, so (1) formula can be reduced to:
Figure C200710064374D00052
I SleepAnd I Search netDepend primarily on portable terminal software and hardware scheme.
T Search netDepend primarily on the speed of hardware and the specific implementation method of search network, can be divided into two kinds of situations: full frequency band is searched the net time T Search entirelySearch the net time T with adjacent sub-district The neighbour searchesFor example, for the TD-SCDMA system, full frequency band is searched net and is meaned in the search of each sub-district on totally 68 frequencies of 2010.8MHz to 2024.2MHz frequency range, and adjacent sub-district is searched net and only the neighbor cell on the same frequency searched for, even thereby search net through the full frequency band of algorithm optimization, it searches the net time T Search entirelyAlso be far longer than adjacent sub-district and search the net time T The neighbour searches
For searching the net period T Cycle, on the one hand, according to (2) formula as can be known, this cycle is big more, average standby current I StandbyMore little, the stand-by time of portable terminal is just long more; And on the other hand, this cycle is big more, and portable terminal is registered to time of sub-district when reentering network's coverage area may be just long more, and be difficult to accept for the user oversize turn-on time again.
According to above analysis, the net strategy of searching that the method for searching network of the described portable terminal of the embodiment of the invention adopts mainly comprises:
1) after portable terminal loses network, intermittently carries out web search.
2) utilize full frequency band to search the net time and search the characteristics of net time much smaller than adjacent sub-district, dispatch dynamically that full frequency band is searched net, these two kinds of different method for searching network of net are searched in adjacent sub-district, the net time T is searched in the equivalence that so both can reduce in (2) formula Search net, can guarantee that again portable terminal arrives available network with bigger probabilistic search.
3) in general, it is long more that portable terminal loses time of network, and it is more little then to search the successful probability of net next time, ensuing search the net cycle should be bigger, and use this search the net cycle to search the net number of times correspondingly littler; But portable terminal should limit maximum searching the net cycle, describedly searches the net cycle and is increased to this and wantonly searches for all after dates of net most and remain unchanged, and can accept to guarantee portable terminal resident time to the sub-district when reentering the network area.
4) in general, when portable terminal has just lost network, still can come back to sub-district or this adjacent cells of cells before the lost network with higher probability, search shorter that the net cycle is provided with this moment, searches the net strategy and adopt adjacent sub-district to search net; If portable terminal do not find network yet, it is elongated then to search the net cycle, searches the net strategy accordingly and adopts full frequency band to search net with the way that net hockets is in proportion searched in adjacent sub-district, and specifically ratio can be provided with (please refer to Fig. 2) flexibly.
5) in the same net of searching the cycle, allow and only allow an external trigger (corresponding to triggering effectively first among the figure, for example button, renovate, slip lid etc.) triggering mobile terminals carries out a full frequency band immediately and searches net, with find as early as possible can be resident network, so both can guarantee the user when needs are made a phone call and just in time available network is arranged with the shortest time access network, unnecessary operations such as button cause portable terminal constantly to search net increase power consumption (please refer to Fig. 3) repeatedly thereby simultaneously also can avoid the user.
6) please refer to Fig. 4, search net in the cycle at one, the generation of external trigger is t constantly Trigger(0≤t Trigger≤ T Cycle) once search before occurring in the very short time after network process finishes (as less than t 1), think that then to search the net probability of successful once more almost nil; Equally, if occurring in next, searches in the very short time that network process is about to begin trigger event (as less than t 2), think that then this incident there is no need triggering and searches network process.Promptly be below trigger event takes place to satisfy constantly, during arbitrary condition, to ignore this trigger event:
0≤t Trigger≤ t 1≤ T Cycle(3)
0≤T Cycle-t Trigger≤ t 2(4)
The external trigger first that (3), (4) formula are not satisfied in generation constantly is effective external trigger, and it triggers a full frequency band and searches network process.Wherein, t 1For full frequency band is searched the net time T Search entirelyWith constant t sometime ConstantSum; t 2Wake pre-set time, software and hardware configuration related register and sign equal time factor up at interior another time constant t ' for considering ConstantWhen specific implementation, can make:
t 1=T Search entirely+ t Constant=t ' Constant=t 2=t (5)
Below provide a concrete application example.
Please refer to Fig. 5, when portable terminal has just lost network, carry out and to search the net flow process when temporarily losing network: portable terminal is searched the network process of searching that the net cycle can dynamically adjust, and searches the net strategy and searches net for adjacent sub-district; Difference is searched the net periodic quantity and is searched the net number of times to what should search the net cycle, and the minimum that net cycle correspondence is searched in maximum adjacent sub-district is searched the net times N Face and searchCan be provided with according to the concrete technical characterstic of portable terminal and network.
When portable terminal has just lost network, at first with the shortest net period T of searching Cycle 1Carry out N 1Net is searched in inferior adjacent sub-district;
If through N 1Inferior adjacent sub-district is searched still can not be resident to proper cell behind the net, then with greater than T Cycle 1Search the net period T Cycle 2Carry out N 2Net is searched in inferior adjacent sub-district, wherein N 2Less than N 1
If through N 1+ N 2Inferior adjacent sub-district is searched still can not be resident to proper cell behind the net, then with greater than T Cycle 2Search the net period T Cycle 3Carry out N 3Net is searched in inferior adjacent sub-district, wherein N 3Less than N 2
If still fail the resident proper cell that arrives, then repeat said process, up to
N i≤ N Face and search(6)
If portable terminal is carrying out N again Face and searchN still can't residently (be supposed to proper cell after searching net in inferior adjacent sub-district in the present embodiment 3=N Face and search), then enter following lose network for a long time search the net flow process.
Please refer to Fig. 6, after the net failure is searched in above-mentioned adjacent sub-district, it is longer that portable terminal loses network time, search the net flow process when then the executive chairman loses network the time: portable terminal is searched the network process of searching that the net cycle can dynamically adjust, search net strategy and search net for full frequency band and search net with adjacent sub-district and hocket in proportion, difference is searched the net periodic quantity and is reached searching searching the net number of times, wantonly searching for the net period T most of net cycle Period m ax, full frequency band searches net and the shared separately ratio of net (ratio in 2:1 in the present embodiment hockets) etc. is searched in adjacent sub-district, can be provided with according to the concrete technical characterstic of portable terminal and network.
Portable terminal has been when the long period has lost network, at first with the short net period T of searching Cycle 4Carry out 2N altogether 4Inferior full frequency band is searched net and N 4Net is searched in inferior adjacent sub-district, and implementation is by the current net period T of searching Cycle 4Do twice full frequency band earlier and search net, do once adjacent sub-district then and search net, repeat this process N 4Inferior;
If through 3N 4Inferior searching still can not be resident to proper cell behind the net, then with greater than T Cycle 4Search the net period T Cycle 5Carry out 2N altogether 5Inferior full frequency band is searched net and N 5Net (N is searched in inferior adjacent sub-district 5Less than N 4), implementation is by the current net period T of searching Cycle 5Do twice full frequency band earlier and search net, do once adjacent sub-district then and search net, repeat this process N 5Inferior;
If through 3 (N 4+ N 5) inferior searching still can not be resident to proper cell behind the net, then with greater than T Cycle 5Search the net period T Cycle 6Carry out 2N altogether 6Inferior full frequency band is searched net and N 6Net (N is searched in inferior adjacent sub-district 6Less than N 5), implementation is by the current net period T of searching Cycle 6Do twice full frequency band earlier and search net, do once adjacent sub-district then and search net, repeat this process N 6Inferior;
If through 3 (N 4+ N 5+ N 6) inferior searching still can not be resident to proper cell behind the net, then terminal is with greater than T Cycle 6Search the net period T Cycle 7Carry out 2N altogether 7Inferior full frequency band is searched net and N 7Net (N is searched in inferior adjacent sub-district 7Less than N 6), implementation is by the current net period T of searching Cycle 7Do twice full frequency band earlier and search net, do once adjacent sub-district then and search net, repeat this process N 7Inferior;
If portable terminal is not resident yet to proper cell, then continue to increase and search the net cycle and carry out the network process of searching under the respective cycle, up to
T Cycle i〉=T Period m ax(7)
After this, portable terminal is all the time with T Period m axFor searching the net cycle, the full frequency band that hockets searches net and net is searched in adjacent sub-district, till searching proper cell.
Wantonly searching for most net periodic quantity, difference searches the number in net cycle, concrete each and searches search the net number of times, full frequency band that net periodic quantity, difference search net cycle correspondence and search net and face the sub-district and search the parameters such as ratio of net and can freely choose according to different portable terminals.Suppose T in the present embodiment Cycle 7=T Period m ax, full frequency band is searched net, and to search the ratio of net be 2:1 with facing the sub-district.
In Fig. 5 or Fig. 6 any one searched net in the cycle, allow and only allow external trigger (for example button, renovate, slip lid etc.) trigger and once search network process, and search the net strategy and search net for full frequency band:
Losing under the network condition, in the current net period T of searching CycleIn, if portable terminal detects external trigger first, and t constantly takes place in this trigger event TriggerSatisfy:
0≤t Trigger≤ t 1≤ T Cycle(8)
Think that then this trigger event is " non-trigger event effectively first ", portable terminal can not trigger a full frequency band and search network process, but waits for that the next one triggers effectively first;
If t constantly takes place in this trigger event TriggerSatisfy
0≤T Cycle-t Trigger≤ t 2(9)
Think that then this trigger event is " non-trigger event effectively first ", portable terminal can not trigger a full frequency band and search network process, but waits for that the next one triggers effectively first;
If t constantly takes place in this trigger event TriggerThe discontented any same form that is enough in (8) (9) is then thought this trigger event for originally searching " trigger event effectively first " in the net cycle, and portable terminal is carried out a full frequency band and searched network process;
Portable terminal is in case after carrying out the full frequency band that is once triggered by " trigger event effectively first " and searching network process, no longer carries out in the cycle and anyly searches network process by what trigger event triggered originally searching net.
In above-mentioned application examples, wantonly search for the net period T most Period m axDo not consider the network parameter before portable terminal loses network, if require when portable terminal has entered the network area by no network area, the stand-by period that makes a call or receive ICQ with have the stand-by period under the network condition suitable substantially, then can consider to lose the network parameter before the network:
Terminal is before losing network, by receiving discontinuous reception (DRX) period T that network broadcast information (BCH) obtains current network DRXAnd Page Indication Channel (PICH) is retransmitted times N PICHThese two parameter values, and write down this two parameter values;
Wantonly search for most the net period T Period m axCan not be greater than before losing network, the DRX cycle T of network settings DRXRetransmit times N with PICH PICHProduct, that is:
T Period m ax≤ T DRX* N PICH(10)
In sum, the method for searching network of the described portable terminal of the embodiment of the invention has reduced the electrical source consumption after portable terminal loses network effectively, has improved the stand-by time of portable terminal.Because the TD-SCDMA system is in the early stage of development, longer following period of time afterwards, the TD-SCDMA network signal must be the part key area in a city, cover part even part city, like this TD-SCDMA terminal lose network probability than higher, thereby the described method of the embodiment of the invention is particularly useful for the portable terminal in the TD-SCDMA system.
Should be noted that at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spiritual scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
