It stays, register
It please refers to Fig.1, the wireless communication terminal Roaming Registration method of division search priority of the invention, including following step
Suddenly：
S100 in advance deposits the signing PLMN information of the currently used communication card operator of wireless communication terminal
Storage；
S101 searches for the optional PLMN that RPLMN/EPLMN and communication card store in itself, and attempts resident and registration, if
It is that (Y) succeeds in registration (S102), then is switched on successfully (S112) and terminates flow；If (N) does not succeed in registration, step is performed
S103：Search for the signing PLMN in pre-stored signing PLMN information lists；
S104, when step S103 searches out the signing PLMN in the signing PLMN information lists, to the label searched out
Signing PLMN in about PLMN information lists attempts resident and registration, if the signing PLMN that (Y) is currently attempted succeeds in registration
(S105), then it is switched on successfully (S112) and terminates flow；If (N's signing PLMN currently attempted) does not succeed in registration, judge current
Whether the reason of signing PLMN registration failures of trial is default reason (S106), which can be according to agreement or engineering
Experience confirms, for example network is refused with #11PLMN not allowed reasons and leads to registration failure etc., if not default original
Cause turns S103, otherwise performs S107：The signing PLMN currently attempted is deleted, and turn from the signing PLMN information lists
S103；
S108, when step S103 does not search out any one of signing PLMN information lists signing PLMN or owns
Search out PLMN in the signing PLMN information lists unregistered success when, search for other PLMN for not storing, i.e., it is described not
Other PLMN of storage are not in the PLMN that RPLMN/EPLMN, communication card store in itself and the signing PLMN information lists
Any one of PLMN, if searching out other PLMN not stored, it tries be resident on the PLMN, register (S109), and
It checks whether the PLMN currently attempted succeeds in registration (S110), when the PLMN registration failures currently attempted, turns S108, continue to search
When the PLMN currently attempted succeeds in registration, the PLMN currently to succeed in registration additions are deposited in advance by other PLMN of Suo Wei storages
In the signing PLMN information lists of storage (S111), be switched on successfully (S112), and flow terminates；If do not search out it is any do not store other
PLMN, then boot failure (S113), flow terminates.
Therefore wireless communication terminal Roaming Registration method of the invention, wireless communication terminal may be searched
PLMN point is different priorities, preferentially attempts RPLMN, the PLMN in the PLMN information that the communication card stores in itself and in advance
PLMN in the signing PLMN information of storage, these PLMN know or in advance facts proved that can succeed in registration,
When only these PLMN were attempted or searched in roaming place less than these PLMN, just attempt to be resident on other unknown PLMN,
Can greatly improve that wireless communication terminal first powers in roaming place in this way registers power and is serviced, and accelerates booting
Speed improves user experience, and inserting any operator suitable for wireless communication terminal is stuck in any roaming network start-up logging.
Lower mask body carries out example for being switched on scene in Hong-Kong after inserting China Mobile and being stuck in inland of China shutdown
Illustrate, it is specific as follows：
Wireless communication terminal setting standard priority is LTE>TDS-CDMA>WCDMA>GSM, currently used communication
Card slot Zhong Cha China Mobile usim card, the HPLMN of the usim card includes 46000 for 46000, EHPLMN lists, 46002,
46007, UPLMN list is empty, and 46000,46002,46007 are included in OPLMN lists.And the wireless communication terminal is in China
Ground 46000 (LTE) registered success, after the wireless communication terminal shuts down, RPLMN 46000.Then usim card stores in itself
PLMN information such as following table：
The signing PLMN information lists of operator of China Mobile, signing PLMN letters are preserved in wireless communication terminal in advance
In breath list the signing PLMN that includes have 45412 (LTE, WCDMA, GSM), 45403 (WCDMA, GSM), 310380 (LTE,
WCDMA, GSM), i.e. step S100 in Fig. 1, specifying information such as following table：
| PLMN | Standard |
| 45412 | LTE |
| 45412 | WCDMA |
| 45412 | GSM |
| 45403 | WCDMA |
| 45403 | GSM |
| 310380 | LTE |
| 310380 | WCDMA |
| 310380 | GSM |
With reference to Fig. 1, which includes the following steps：
In Hong-Kong, net is searched in booting to wireless communication terminal, does not find 46000,46002,46007, such as step S101,
S102；
Searching net checks Hong-Kong in eating dishes without rice or wine with the presence or absence of signing PLMN:45412(LTE,WCDMA,GSM),45403
(WCDMA, GSM), 310380 (LTE, WCDMA, GSM) cell signals, such as step S103；
The signal of these cells is searched out in eating dishes without rice or wine in Hong-Kong：cell1(45414,LTE),cell2(45403,
WCDMA),cell3(45412,LTE).The signal strength of these cells is followed successively by：cell1>cell2>Cell3, due to 45403
(WCDMA), 45412 (LTE) are present in pre-stored current operator signing PLMN information lists, and LTE standards are preferential
Grade higher, terminal selection cell3 (45412, LTE) attempt resident, registration, such as step S104, if in cell3 (45412, LTE)
On be resident, succeed in registration, such as step S105, then be switched on success, such as step S112, can then terminate flow；If in cell3
It is resident on (45412, LTE), registration failure, judges to note whether failure cause is specific reasons, such as step S106, when being default original
Because when, by 45412 (LTE) from pre-stored current operator contract PLMN information lists in delete, such as step S107.Later
Terminal selection cell2 (45403, WCDMA) attempts resident, registration, such as step S104, later process with attempt cell3 (45412,
LTE process) is the same.If the also registration failure on cell2 (45403, WCDMA), by 45403 (WCDMA) from pre-stored
It is deleted in current operator signing PLMN information lists, such as step S107.
Due to the cell3 (45412, LTE), the cell2 (45403, WCDMA) that search out, i.e., pre-stored current operator
PLMN in signing PLMN information lists), equal registration failure, therefore other PLMN for attempting not store can only be transferred, i.e., terminal is selected
It selects cell1 (45414, LTE) and attempts resident, registration, such as step S108, S109, if being registered on cell1 (45414, LTE)
45414 (LTE) are then added in pre-stored current operator signing PLMN information lists, are switched on successfully by work(, flow knot
Beam, such as step S110, S111, S112.
If the also registration failure on cell1 (45414, LTE), then boot failure, flow terminate, such as step S113.
