It contains when user terminal selecting try accessed wireless accessing technology RAT network and located public land mobile network PLMN, and attempt accessing relevant RAT network, user terminal receiving network side returned accessing failing message, no longer recording said PLMN to prohibiting PLMN, but directly continue searching other usable network. Said invention can ensure user terminal reliably roaming to signatory RAT network instead of influencing by not signatory RAT network of said service provider when using same PLMN establishing 2G, 3G network.
Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of implementation method of controlling user terminal access PLMN.
Background technology
Along with development of Communication Technique, 3G (3-G (Generation Three mobile communication system)) network has begun progressively commercial in the whole world.But need a long-term process but 3G network is finished alternative 2G (second generation mobile communication system) network, so the situation of 2G network and 3G network coexistence will continue the long time.For this reason, the dual-mode handset that can be applied to respectively in 2G network and the 3G network has occurred, and the dual RAT that adopts in dual-mode handset (Radio Access Technology, wireless access technology) promptly can support to insert different RAT networks.
That is to say that the 2G network may use identical PLMN (Public Land Mobile Nerwork) with 3G network at present.And two kinds of RAT may be provided in the PLMN network usually: a kind of RAT network may insert, roam for not allowing the user, and another RAT network may insert for signatory back allows the user, roaming; It is that PLMN may comprise: the RAT network that can insert, roam after RAT network that a kind of user of forbidding inserts, roams and a kind of the contracting.Usually UE (User Equipment, subscriber equipment) can select to be in and initiate to insert processing procedure in any one RAT network.
In the UE communication process, if UE attempts when the enterprising line position of the RAT network that does not allow to insert, roam upgrades or registers, 11 or 13 message that network side just can return to UE, after receiving 11 or 13 message, then determine UE in this PLMN, be under an embargo accesss, roam, wherein, the implication of described 11 message is: PLMN not allowed (PLMN does not allow to insert), the implication of described 13 message is: NATIONAL_ROAMING_NOT_ALLOWED{ does not allow roaming at this LAI (band of position identification code) }.
When UE (being mobile phone) received 11 or 13 message of returning, according to the regulation of 3GPP 24.008 agreements, UE needed this PLMN is written among the FPLMN (PLMN that forbids), and the PLMN that writes among the FPLMN shows that UE does not allow to insert, roaming in this PLMN.Like this, after being rejected on a kind of RAT network of UE at this PLMN,, also will be written into FPLMN, and make UE can't register access, also can't realize roaming certainly because of this PLMN even signatory another kind of the permission inserted, roamed the RAT network.
Be not difficult to find out, above-mentioned prior art will cause working as mobile phone after being rejected roaming on a kind of RAT network of certain operator, its signatory in addition RAT network also will be written into FPLMN because of this PLMN, and can't register, even and then make signatoryly another kind ofly allow to insert, the RAT network of roaming, can't guarantee that also UE can realize inserting, roaming, this obviously can't satisfy user's application demand, simultaneously, make operator to provide and make customer satisfaction system service.
Summary of the invention

Embodiment
Main purpose of the present invention is to solve to use identical PLMN at 2G network and 3G network, a kind of RAT network does not allow to insert, roaming, and under the situation that allows behind another RAT network contraction to insert, roam, dual-mode handset UE causes also can't realizing the problem that inserts, roams in signatory RAT network behind the RAT network of attempting not allowing to insert, roam.
For the present invention there being further understanding, will the specific implementation of method of the present invention be described in detail below.
Among the present invention, suppose in the 2G and 3G network of same PLMN that a kind of RAT network does not allow to insert, roaming, and another RAT network contraction allows to insert, roaming.At this moment, the specific implementation of method of the present invention may further comprise the steps as shown in Figure 1:
Step 11: in PLMN, UE attempts when the enterprising line position of the RAT that does not allow to insert, roam upgrades or registers, and network returns 11 or 13 message to UE;
Step 12:UE receives this message, no longer described PLMN is written to FPLMN;
Step 13: judge whether current RAT also exists other available networks, if having, then execution in step 14, otherwise, execution in step 15;
Step 14: determine that also there are other available networks in RAT, then attempt carrying out position renewal or registration to other available networks, when each network of this RAT all can't be realized position renewal or registration, execution in step 15; Certainly, if realize that in other available networks the position is upgraded or registration, then insert, roam processing procedure accordingly and finish;
Step 15: when UE attempts position renewal or registration failure in a kind of RAT network, then switch to another kind of new RAT and search for another kind of RAT network again;
Like this, if in this PLMN, searched signatory RAT network, just can carry out position renewal or registration, thus can satisfy access, the roaming needs of UE, make things convenient for operator to provide access service flexibly for user terminal.
Among the present invention, described RAT network can be AMPS (Advanced Mobile Phone System) network, CDMA IS95 (Narrowband CDMA) network, the CDMA2000 network, EV-DO (strengthening the CDMA2000 of data service) network, GSM (digital cellular mobile communication systems) network, WCDMA (Wideband Code Division Multiple Access (WCDMA)) network or TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) network, WLAN (WLAN (wireless local area network)) network, WIMAX network, or the like.
In the processing procedure that the invention described above provides, if in this PLMN, do not search available RAT network all the time, perhaps upgrade or all failures of registration trial, then this PLMN can be written among the FPLMN, show and forbid among this PLMN that this UE inserts, roaming at the position of each RAT network.
Can also realizing in the following ways in specific implementation process of the method for the invention as shown in Figure 2, specifically may further comprise the steps:
Step 21: the PLMN that record of storage inserts in the file system of mobile phone (being UE), roaming is refused and the form of the RAT network information, be called for short access roaming refusal table, as shown in table 1:
Table 1
| (U)SIM ID(10bytes) | PLMN identifies (3bytes) | RAT identifies (1byte) |
| 1 | ||
| 2 | ||
| N |
In this table, the information of record comprises (U) SIM ID (whole subscriber identification module sign), PLMN sign and RAT sign, when UE upgrades or during registration at the enterprising line position of certain RAT network of certain PLMN, 11 or 13 the message of receiving that network side returns, then that UE is current (U) SIM ID, PLMN sign and RAT identification record are in table 1;
Among the present invention, described access roaming refusal table can be the dynamic or static table of preserving;
If adopt dynamic table as access roaming refusal table, then the sign of (U) SIM in the table can be saved; This is because when UE changed card, the record of this dynamic table will be removed automatically;
If adopt static table as access roaming refusal table, then the sign of (U) SIM in the table both can keep, and also can save:
(1) when having comprised the USIM sign in the table, mobile phone can identify the login refusal situation of distinguishing same subscriber card by this; But mobile phone can not frequently change card in this case, perhaps, mobile phone will have the predetermined list item deletion strategy that writes down in the delete list, such as the maximum that table record is set, reach after the some so that in table, write down, those long-term no record deletions;
(2) when not comprising (U) SIM when sign in the access roaming refusal table, then should preserve the sign of active user's card in the mobile phone, when changing card, mobile phone by the comparison neocaine sign and whether the sign of the card of preservation consistent judges whether to change card; This judges it generally is to carry out when start, and, when definite mobile phone changes card, then need to remove the record in the described access roaming refusal table;
Step 22: when UE moves to field network or starts shooting again, then will search corresponding RAT network signal and select a certain RAT network automatically, promptly UE determines to attempt position renewal or the RAT network of registration and the PLMN at place;
Step 23: check whether this RAT network place PLMN is present among the FPLMN,, determine that then described PLMN forbids that this UE inserts if exist, execution in step 24, otherwise, execution in step 25;
Step 24: search for other networks of current RAT, and judge whether to search other available networks, when searching corresponding available RAT network and determining corresponding PLMN, execution in step 23; If do not search other available RAT networks, then execution in step 29;
Step 25:, continue to check described access roaming refusal table, i.e. table 1 if not in FPLMN, if current (U) SIM is ID, desire the PLMN sign of network selection network and current RAT network identity does not find coupling in table 1 record, then execution in step 26, otherwise, execution in step 24;
Step 26: allow UE to attempt this PLMN network of registration, and carry out corresponding position and upgrade;
Step 27: when UE upgrades or during registration at the enterprising line position of certain RAT network of certain PLMN, judge that the position is upgraded or whether registration is successful, if network returns 11 or 13 message to UE, determine that then the position is upgraded or the registration process failure, after UE receives this message, execution in step 28, if UE receives the message that the position is upgraded or succeeded in registration, then processing procedure finishes;
Step 28: the PLMN sign and the current RAT network identity of current (U) SIM ID, refusal access roaming are recorded in the described access roaming refusal table, and no longer this PLMN is written among the FPLMN, and execution in step 24;
Step 29: if current RAT does not have other available networks, then switch to another kind of RAT, the new search network of laying equal stress on is determined the PLMN at corresponding RAT network and place thereof, and execution in step 23 is until its access network.
Description by said process as can be seen, according to the rule of access roaming refusal table, the RAT that identical PLMN is different can be treated with a certain discrimination, has solved the problem that prior art exists, thereby has satisfied the requirement of operator.
And, be provided with described access roaming refusal table after, can effectively reduce the number of times that UE attempt to insert, improve the efficient of access roaming.
Among the present invention, for meeting the corresponding protocol requirement, if the refusal record of all RAT of the corresponding mobile phone support of certain PLMN institute of current (U) SIM ID of record in the described access roaming refusal table, promptly determine that according to access roaming refusal table UE all can't insert a certain PLMN by all RAT of its support, then this PLMN is write FPLMN, and corresponding record in the deletion access roaming refusal table.
Among the present invention, when UE manually attempts being registered to the RAT of certain PLMN, then need not to check FPLMN and access roaming refusal table, after succeeding in registration, check when in the access roaming refusal table matched record being arranged the deletion corresponding record.
For this reason, among the present invention, can be the maintenance interface that UE provides access roaming refusal table, make the user can delete, many or whole record in this table.Like this, once when certain RAT network of certain PLMN of registration, be rejected (making its corresponding information be recorded in the access roaming refusal table) though can guarantee mobile phone, but, as long as when it opens roaming, by of the relevant information deletion of described maintenance interface, just can recover UE and under this RAT network of corresponding PLMN, realize access roaming record in the access roaming refusal table; Certainly, also can revise described access roaming refusal table automatically by UE.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
