In order to solve the mobile terminal start overlong time in net when international roaming present in prior art
Problem, embodiments provide a kind of web search scheme.In this technical scheme, work as mobile terminal
After start, the search order that the domestic network being first according to pre-set indicates carries out domestic network search, when
Do not search PLMN, or the national code indicated by the PLMN searched is this mobile terminal SIM
The national code of non-attribution state time, carry out international networks according to the search order of the international network standard pre-set
Network is searched for.Compared with prior art, eliminate the transition timer that state's internal schema switches to International Model, move
Dynamic terminal has only in the case of meeting above-mentioned search condition to be quickly switched in International Model, thus
Save the mobile terminal start time in net when international roaming.
Below in conjunction with Figure of description, embodiments of the invention are illustrated, it will be appreciated that described herein
Embodiment be merely to illustrate and explain the present invention, be not limited to the present invention.And in the feelings do not conflicted
Under condition, embodiment and the feature of embodiment in the present invention can be combined with each other.
Embodiments provide a kind of network search method, as it is shown in figure 1, be the realization stream of the method
Cheng Tu, specifically includes following step:
Step 11, after mobile terminal-opening, is carried out according to the search order of the domestic network standard pre-set
Domestic network is searched for.
Under normal circumstances, the search order of domestic network standard can be configured according to 4G → 3G → 2G.
As a example by supporting the three mould mobile terminals of TD-LTE, TD-SCDMA and GSM under domestic scene, carry out
The order of domestic network search can be: TD-LTE → TD-SCDMA → GSM.
Step 12, when do not search public land mobile network (Public Land Mobile Network,
Or the national code indicated by PLMN that searches is this mobile terminal client identification module PLMN),
During the national code of the non-attribution state of (Subscriber Identity Module, SIM), according to pre-set
The search order of international network standard carries out international network search.
In embodiments of the present invention, owing to eliminating the transition timer that state's internal schema switches to International Model,
Mobile terminal has only in the case of meeting above-mentioned search condition can be quickly switched in International Model, from
And save the mobile terminal start time in net when international roaming.
It addition, the embodiment of the present invention can also realize contracting by the volumes of searches after reducing mobile terminal-opening
Net spee is stayed in the start of short mobile terminal.
The mode of the volumes of searches after the first minimizing mobile terminal-opening:
In step 12, mobile terminal, according to the search order of the international network standard pre-set, is carried out
International network unduplicated with domestic network standard is searched for.
To support TD-LTE, TD-SCDMA and GSM under domestic scene, support under international roaming scene
As a example by the multi-module mobile terminal of TD-LTE, FDD LTE, WCDMA and GSM, carry out domestic network and search
The order of rope is: TD-LTE → TD-SCDMA → GSM, then order when carrying out international network search is:
FDD LTE→WCDMA。
In this manner, due to the web search results in International Model Xia Bu repeat search state internal schema,
Volumes of searches after mobile terminal-opening is reduced, thus saves the start time in net of mobile terminal further
Between.
The mode of the volumes of searches after the second minimizing mobile terminal-opening:
When domestic network standard includes GSM, according to the domestic network pre-set in above-mentioned steps 11
When the search order of standard carries out domestic network search, can be, but not limited to realize as follows:
When carrying out domestic network search according to GSM network standard, only to the in GSM network standard
One frequency range scans for；Wherein, the first frequency range is the GSM frequency range belonging to state of mobile terminal SIM.
As a example by the ownership state of mobile terminal SIM is as China, the GSM frequency range of China be 900MHz and
1800MHz, then when carrying out domestic network search according to GSM network standard, only to GSM network system
900MHz and 1800MHz in formula scans for；
Still without when searching PLMN after the first frequency range has been scanned for, then continue GSM net
The second frequency range in network standard scans for；Wherein, this second frequency range is the ownership state except mobile terminal SIM
GSM frequency range outside GSM frequency range.
Now step 12 can be, but not limited to specifically include:
When not searching PLMN after the second frequency range has been scanned for, or the first frequency range is being entered
The non-attribution state that the national code indicated by PLMN is mobile terminal SIM searched during line search
National code time, or the state indicated by PLMN searched during the second frequency range is scanned for
When family's code is the national code of non-attribution state of mobile terminal SIM, according to the international network standard pre-set
Search order carries out international network search.
In this manner, it is assumed that mobile terminal is in roaming country, when after mobile terminal-opening at GSM net
When the first frequency range in network standard carries out domestic network search, due to the ownership state of mobile terminal SIM
The GSM frequency range of GSM frequency range and non-attribution state there may be identical frequency, and therefore mobile terminal is at GSM
When the first frequency range in network formats carries out domestic network search, it is more likely that the national code of instruction can be searched
For the PLMN of national code of the non-attribution state of mobile terminal SIM, now mobile terminal is without to GSM
The second frequency range in network formats scans for, just can directly from domestic patten transformation to International Model, from
And decrease volumes of searches originally, save the start time in net of mobile terminal.
The mode of the volumes of searches after the third minimizing mobile terminal-opening:
During carrying out international network search according to the search order of the international network standard pre-set,
Once search the PLMN of the national code of the non-attribution state that national code is described mobile terminal SIM of instruction
Time, attempt resident community corresponding for the PLMN searched at once.
Compared with prior art, it is not necessary to the most resident after having waited the search of whole standard, shifting is therefore decreased
Volumes of searches after dynamic starting up of terminal, net spee is stayed in the start shortening mobile terminal.
In embodiments of the present invention, if searching according to the international network standard pre-set in step 12
Suo Shunxu carries out after international network searched for, when the most not searching PLMN, then can starting in advance
The protection intervalometer arranged, after this protection timer expiry, more again according to the domestic network pre-set
The search order of standard carries out domestic network search.
If there is no protection timer mechanism, it is assumed that be in network black spots during mobile terminal-opening, first press
Search order according to the domestic network standard pre-set carries out domestic network search, owing to mobile terminal is in
Off-grid state, the most necessarily searches for less than PLMN, and now mobile terminal can be according still further to the world pre-set
The search order of network formats carries out international network search, carries out domestic network search the most again.I.e. mobile whole
End is absorbed in the endless loop search of state's internal schema → International Model → state's internal schema, so can waste mobile terminal
Power consumption.And the embodiment of the present invention arranges protection timer mechanism and is advantageous in that, mobile terminal can be reduced
Power consumption, make mobile terminal avoid under off-grid state and carry out futile searches.
In order to be better understood from the embodiment of the present invention, implement the tool to the embodiment of the present invention below in conjunction with concrete
Body implementation process illustrates.
With SIM ownership state be China mobile terminal (under domestic scene support TD-LTE,
TD-SCDMA、GSM；TD-LTE, FDD LTE, WCDMA, GSM is supported) under international roaming scene
As a example by, the network search method provided in the embodiment of the present invention is as in figure 2 it is shown, specific as follows:
First stage: after mobile terminal-opening, suitable according to the search of TD-LTE, TD-SCDMA, GSM
Sequence do corresponding frequency, frequency range scanner uni physical layer to radio resource control (Radio Resource
Control, RRC) the reporting of layer, wherein GSM only scans the GSM frequency range of this country, and such as China is
900MHz and 1800MHz.If searching the letter of RPLMN, HPLMN, UPLMN, OPLMN
Number, then mobile terminal is attempted resident immediately；If do not search out the national code of this country yet when terminating the scanning of this stage,
Such as China is 460, but has searched out the national code of other countries, then be immediately performed state's internal schema to international
The conversion of pattern.
Second stage: if not searching any PLMN at first stage mobile terminal, then start non-originating
Scanner uni physical layer the reporting to rrc layer of GSM band scan, such as 850MHz/1900MHz.If
Do not search out this country's national code in this second stage, but search out the national code of other countries, be then immediately performed state
Internal schema is to the conversion of International Model.
Phase III: if not searching any PLMN in first stage and second stage mobile terminal, then exist
The conversion of state's internal schema-> International Model is started after completing the scanning of GSM.After entering International Model, mobile
Terminal perform standard correspondence frequency that pattern at home do not scans, frequency range scanner uni physical layer to rrc layer
Report.If not searching out this country's national code in this phase III, but search out the national code of other countries,
Network selection process under state of enforcement's internet roaming the most at once.
Fourth stage: if not searching any PLMN in first stage, second stage and phase III, then
Starting protection intervalometer, mobile terminal carry out after this protection timer expiry International Model-> state's internal schema it
Between conversion.
With a specific embodiment, the aforementioned four stage is illustrated below:
TD-LTE multimode terminal shuts down after residing in domestic network, under international roaming environment, and such as Korea S
Start.Now the network environment residing for this terminal is LTE FDD, WCDMA.According to above four-stage
Description, this terminal net flow process of searching after roaming place (Korea S) first powers on is:
First stage: terminal is according to TD-LTE-> TD-SCDMA-> GSM (900MHz+1800MHz)
Sequential search correspondence frequency, frequency range, do not search any PLMN, starts second stage search；
Second stage: terminal incremental search GSM (950MHz+1900MHz), does not searches any
PLMN, carries out the conversion of state's internal schema-> International Model, starts phase III search；
Phase III: terminal searching LTE FDD and WCDMA, now search non-460 national codes
Signal, such as the LTE FDD signal of KT-45008, and signal quality meets the thresholding of terminal persistent district,
Terminal is attempted resident at once.
In embodiments of the present invention, terminal does ENCREMENT NETWORK search according to different network environments, and in the world
The web search results of pattern Xia Bu repeat search state internal schema, eliminates state's internal schema to International Model simultaneously
The transition timer of switching so that mobile terminal has only in the case of meeting above-mentioned search condition can be fast
Speed is switched in International Model, thus saves the mobile terminal start time in net when international roaming.
During it addition, mobile terminal searches for network under International Model, if finding community that can be resident, the longest
Time resident, it is not necessary to the most resident after having waited the scanning of whole standard, save the starting up of terminal time in net.
