Example, shall fall within the protection scope of the present invention.
As shown in Figure 1, the step flow chart of the method for LTE network, this method are accessed for terminal in the embodiment of the present invention
Include the following steps：
Step 101, start and during having not timed out in T3402 timers, when detecting terminal in addition to LTE network
Other networks in cell registration when, at interval of preset time obtain endpoint registration cell cell information.
Specifically, before the startup of T3402 timers, terminal can search network planning then according to default, select qualified
LTE cells are attempted to initiate Attach or TAU, then judge whether the entry condition for having reached T3402 timers.
It should be noted that default network planning of searching then includes but not limited to the original specification of agreement and the network selection by optimization
Flow.In addition, the entry condition of T3402 timers includes but is not limited to Attach or the TAU failure 5 of agreement primitive request
It is secondary, various to forbid still failing after (Bar) optimizing cells and the optimization of various number of retries modification etc..
Wherein, it when the not up to entry condition of T3402 timers, such as is arrived according to specification flow normal registration
LTE network, handover network pattern are preferential or LTE registrations caused by opening the modes such as off-line mode stop for 3G network, then press
Subsequent process is completed according to specification flow.
Wherein, when the entry condition for reaching T3402 timers, then during T3402 timers start and have not timed out,
Can with detection terminal whether the cell registration in other networks in addition to LTE network, wherein, which can include
2G networks or 3G network.
When detecting cell registration of the terminal in other networks in addition to LTE network, can at interval of it is default when
Between obtain endpoint registration cell cell information.
Specifically, cell information can include wireless access technology (Radio Access Technologies, abbreviation
RAT), in cell ID and signal strength information at least one of.Wherein, it is strong can to include received signal for signal strength information
Degree instruction (Received Signal Strength Indication, abbreviation RSSI), Reference Signal Received Power
(Reference Signal Receiving Power, RSRP) and signal-to-noise ratio (SIGNAL-NOISE RATIO, abbreviation SNR)
At least one of in.
It should be noted that the value range of the preset time at interval can be 5s to 30s.In this way so that will not
Too short due to being spaced, obtaining information frequently influences very much the operation of performance or other modules, will not it is too long due to interval time and
The run time for leading to whole operation flow is longer, so as to influence the time of terminal access LTE network.
Step 102, it according to the cell information of endpoint registration cell obtained at interval of preset time, detects whether to weigh
New search LTE network.
In this step, specifically, in the cell information according to the endpoint registration cell obtained at interval of preset time, inspection
Whether survey when can re-search for LTE network, can obtain the cell information of the first registration cell recorded during first time with
The cell information of the second registration cell recorded during the second time, then by the cell information of the first registration cell and the second registration
The cell information of cell is compared, and determines whether that LTE network can be re-searched for.Wherein, the second time and first time
Between be spaced preset time, specifically, at the first time can be current time, at this time the second time for current time space before it is pre-
If the time during time；Cell information includes：Wireless access technology (abbreviation RAT), cell ID (abbreviation ID) and signal strength
At least one of in information.
Wherein, the cell information of the first registration cell is compared with the cell information of the second registration cell, judgement is
It is not no when can re-search for LTE network, following item can be included：
First, the first RAT of the first registration cell is compared with the 2nd RAT of the second registration cell, if comparing
To the first comparison result to determine to occur RAT switchings, then judgement can re-search for LTE network.Such as terminal is in T3402
Timer is registered in 2G networks, but reside in 3G network in current time when starting, it may be considered that being that change of network environment is drawn
The variation of resident network has been played, that is, RAT switchings have had occurred, then can be determined that at this time can re-search for LTE network.
If second, the first comparison result for determine do not occurred RAT switching when, by first registration cell the first ID with
2nd ID of the second registration cell is compared, if compare the second obtained comparison result to determine to occur cell switching,
Judgement can re-search for LTE network.For example, terminal resides in the A cells of 2G networks when T3402 timers start, but
Current time terminal resides in the B cells of 2G networks, it may be considered that be the variation that change of network environment causes resident network,
Cell switching has occurred, then can be determined that at this time can re-search for LTE network.
Third, if to determine cell switching did not occurred for the second comparison result, by the first signal of the first registration cell
Strength information is compared with the second signal strength information of the second registration cell, if it is small to compare obtained third comparison result
When area's signal strength changes and cell signal strength changing value is more than predetermined threshold value, judgement can re-search for LTE network.
For example, terminal resides in the A cells of 2G networks when T3402 timers start, 2G nets are equally resided in current time terminal
The A cells of network, but the changing value for detecting RSSI of the cell when current time starts compared with T3402 timers then may be used more than 5db
To be considered that change of network environment causes the variation of resident network, i.e. cell signal strength changing value is more than predetermined threshold value, then
Can be determined that at this time can re-search for LTE network.
In this way, whether terminal when first time is compared with the second time to that RAT switchings occurred successively, was cut RAT does not occur
Cell switching whether occurred when changing and whether cell signal strength variation is more than predetermined threshold value when cell switching does not occur,
As the condition for judging whether can to re-search for LTE network, avoid terminal carry out LTE cells blindly frequently search when it is easy
Search failure and the scene for increasing power consumption so that terminal can carry out LTE network search when meeting one of condition,
Realizing can quickly judge whether that LTE network can be re-searched for.
Step 103, when detect can re-search for LTE network when, obtain at least one mesh for searching for of LTE network
Mark LTE cells.
In this step, specifically, detect can re-search for LTE network when, carry out LTE network search, and obtain
Take at least one target LTE cells that LTE network is searched for.
It wherein, can be when detect can when obtaining at least one target LTE cells that LTE network is searched for
When re-searching for LTE network, the identification information of all LTE cells that LTE network is searched for is obtained and recorded；Then it obtains and draws
Play the identification information for the LTE abnormal cells that T3402 timers start；It is finally different according to the identification information of all LTE cells and LTE
The identification information of Chang little Qu, obtains other LTE cells in addition to LTE abnormal cells in all LTE cells, and by other LTE
Cell is recorded as target LTE cells.Specifically, identification information can include Physical Cell Identifier (Physical Cell
Identifier, abbreviation PCI) and frequency point.Specifically, when obtaining target LTE cells, all LTE cells can be first determined
The other identifier information except the identification information of LTE abnormal cells is removed in identification information, it is then that other identifier information institute is right
Other LTE cells answered are recorded as target LTE cells.In this way so that terminal is sending access at least one target LTE cells
During request, will not access request be sent to LTE abnormal cells again, avoid repetition and send access request to LTE abnormal cells
The generation of scene.
It should be noted that LTE network can be re-searched for detecting, and when carrying out LTE network search, not
The continuation timing of T3402 timers is influenced, i.e., on the basis of the continuation timing of T3402 timers, carries out LTE network search.
In addition, specifically, when detect can re-search for LTE network when, if not searched for when carrying out LTE network search
To target LTE cells, then enter the step of obtaining the cell information of endpoint registration cell at interval of preset time, so that energy
The cell information of endpoint registration cell that enough foundations reacquire, to continue to detect whether that LTE network can be re-searched for, from
And increase the chance that LTE network is accessed before T3402 timer expiries.
Certainly, it should be noted that when detecting T3402 timer expiries, then needs to remove at interval of default
The cell information for the endpoint registration cell that time gets and the cell information of target LTE cells, and according to LTE protocol specification weight
New search network.
Step 104, access request is sent at least one target LTE cells, so that terminal accesses at least one target LTE
One of target LTE cells in cell.
In this step, specifically, access request can include Attach requests and TAU requests.
Wherein, when getting at least one target LTE cells, it can send and access at least one target LTE cells
Request so that terminal accesses one of target LTE cells at least one target LTE cells, exists so as to improve terminal
