Abstract

This invention relates to a method for controlling access of user terminals including: setting up an access panning refusing list in a user identification module to register the PLMN and RAT network information for refusing access and panning, when the terminal refreshes positions or registers on the RAT network of a PLMN, it looks for the refusing list based on the PLMN and the RAT marks, if it can't find the correct registration, it is permitted to try the refreshment or registration.

Description

The method that control terminal inserts

Technical field

The present invention relates to wireless communication technology field, relate in particular to the method that a kind of control terminal inserts.

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.And the mixing multi mode terminal of the different radio access technologies of 2G or 3G also occurs such as the GSM-CDMA mobile phone of CHINAUNICOM.Multi mode terminal can switch mutually between multiple access technology.Mobile phone is when attempting to insert a RAT network that does not activate the service, and network returns specific refuse information, after UE receives message, can be written to the PLMN of this network sign among the FPLMN.

Multi mode terminal is when attempting to insert a RAT network that does not activate the service, and network returns specific refuse information, after UE receives message, can be written to the PLMN of this network of mobile phone sign among the FPLMN.Like this, for different wireless access technology RAT networks for example GSM and CDMA, perhaps 2G and 3G network for example GSM use identical PLMN with WCDMA, a kind of RAT does not allow roaming, and another RAT signing contract of admission random.UE attempts when the enterprising line position of the RAT that does not allow to roam upgrades or registers, can be written to this PLMN among the FPLMN because network can return particular message, working as UE like this has been rejected on this PLMN RAT, the RAT of another kind of signatory roaming is because PLMN has write FPLMN, and UE also can't register.

For example, 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, such as an experimental network or pre-commercial 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) receives 11 or 13 message of returning, regulation according to 3GPP 24.008 agreements, UE needs this PLMN is written among the forbidding PLMN (PLMN that forbids), and the PLMN that writes among the forbidding PLMN 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 forbidding PLMN, 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.

Such as, world's wind dual-mode handset of CHINAUNICOM can insert GSM and cdma network simultaneously, supposes that Malaysian A operator has also runed GSM and cdma network, and two shared same PLMN signs of network.CHINAUNICOM and A operator have signed about GSM international roaming agreement, the GSM mobile handset of CHINAUNICOM can roam into the A carrier network, and the CDMA mobile phone not all right (such as, the cdma network of A operator still is in test operation and receives the stage, CHINAUNICOM also is not able to do in time and roaming agreement about the CDMA mobile phone is signed by portion of A operator), at this moment, when CHINAUNICOM world wind dual-mode handset roams into A carrier network mulched ground, when if mobile phone at first selects the cdma wireless access technology to attempt inserting the CDMA trial run network of A operator, network can be refused its access, at this moment, mobile phone can write the PLMN sign of A carrier network in the forbidding PLMN table (Forbidden PLMN table is called for short the FPLMN table).After this, when mobile phone is attempted to insert the GSM network of A operator, can make UE can't register the GSM network of A operator because the PLMN of A operator has been written into forbidding PLMN.

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 forbidding PLMN 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

In view of above-mentioned existing in prior technology problem, the purpose of this invention is to provide a kind of method that user terminal inserts of controlling, make user terminal to roam reliably and be linked into its signatory RAT network.

The objective of the invention is to be achieved through the following technical solutions:

The invention provides a kind of method that user terminal inserts of controlling, this method comprises:

A, in subscriber identification module, set up access roaming refusal table with register reject insert, the PLMN and the RAT network information of roaming;

B, when terminal the enterprising line position of the RAT of certain PLMN network upgrade or registration in, search described access roaming refusal table according to PLMN and RAT sign, if in last table, can not find corresponding record, then allow terminal to attempt the renewal of described position or register.

Preferably, steps A further is: set up the RAT identity property in the forbidding PLMN table in present subscriber identification module it is expanded to access roaming refusal table.

In another preferred embodiment of the present invention, steps A further is: an access roaming refusal table is set separately in subscriber identification module, comprises PLMN and RAT identity property in the described access roaming refusal table.

Preferably, described method also comprises: when user terminal was received the message of the trial access failure that network side returns, then the PLMN information with described RAT network and place thereof recorded in the described access roaming refusal table.

Described method also comprises: when user terminal is manually attempted inserting success or opened roaming, if corresponding RAT network and corresponding PLMN information thereof are recorded in the described access roaming refusal table, then should write down deletion from this table automatically.

Described RAT network is: AMPS network, CDMA IS95 network, CDMA2000 network, EV-DO network, GSM network, WCDMA network, TD-SCDMA network, wlan network or WIMAX network.

As seen from the above technical solution provided by the invention, realization of the present invention makes operator use identical PLMN to build 2G, 3G network, or when building an experimental network, under the RAT network condition that can not contract all because of reasons such as network evolution or commercial operations, guarantee that user terminal can roam in the signatory RAT network reliably, thereby avoided in the user terminal roaming access procedure, be subjected to the not influence of signatory RAT network among the same PLMN of this operator.

Embodiment

Main purpose of the present invention is to solve to use identical PLMN at 2G network and/or 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, of the present invention

Step 11: in subscriber identification module, set up access roaming refusal table, can be by expanding the FPLMN table in the present subscriber identification module, set up the RAT identity property therein and make it to become access roaming refusal table, also can set up access roaming refusal table separately in subscriber identification module, described subscriber identification module comprises UIM card, SIM card and usim card; In this table, the information of record comprises 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 PLMN sign and RAT identification record are in this is shown; Described roaming admission reject table can adopt down column format:

Table 1

	PLMN identifies (3 bytes)	RAT identifies (1 byte)
	PLMN identifies (3 bytes)	RAT identifies (1 byte)	1
2			1
2			N

Step 12: when UE the enterprising line position of certain RAT network of certain PLMN upgrade or registration in, search described access roaming refusal table according to network PLMN and RAT sign,, then enter step 13 if in last table, can not find corresponding record, otherwise, enter step 14.

Step 13: attempt registering this network and judging whether to succeed in registration; Then enter step 17 finishes if succeed in registration.

Step 14: judge whether current RAT also exists other available networks, if having, then execution in step 15, otherwise, execution in step 16;

Step 15: 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, certainly, if realize that in other available networks the position is upgraded or registration, then insert, roam processing procedure accordingly and finish;

Step 16: then switch to another kind of new RAT and search for another kind of RAT network again.

Like this, if in certain PLMN, searched signatory RAT network, just can carry out the position more

Like this, if in certain 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, when UE manually attempts registering the RAT of certain PLMN, do not look into described access roaming refusal table, after registration was gone up, UE looked into described access roaming refusal table according to the PLMN at current RAT sign and place, and with the corresponding record deletion of finding.

Among the present invention, described RAT network can be: AMPS (Advanced Mobile Phone System) network, CDMA IS95 (Narrowband CDMA) network, CDMA2000 network, EV-DO (strengthening the CDMA2000 of data service) network, WLAN (wireless local area network) wlan network, WIMAX 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, or the like.

Description by said process as can be seen, according to the rule of described 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.And when being used for other UE with subscriber identification module, the user still can reach effect same.

Therefore, among the present invention, can also provide the maintenance interface of described 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 described access roaming refusal table) though can guarantee mobile phone, but, as long as when it opens roaming,, just can recover UE and under this RAT network of corresponding PLMN, realize access roaming the relevant information deletion of writing down in the described expansion in the subscriber identification module by described maintenance interface.

Fig. 2 is the flow chart of the present invention's one specific embodiment, comprising:

Step 21: by setting up the RAT identity property in the FPLMN table in present subscriber identification module, make it to expand to access roaming refusal table, the FPLMN of described expansion can adopt down column format:

Table 2

Step 22:UE determines to attempt RAT network and the corresponding PLMN that the position is upgraded or registered;

Step 23: check whether this RAT network and corresponding PLMN thereof are present in the FPLMN table of expansion, if then execution in step 24, otherwise execution in step 26;

Step 24: judge whether current RAT searches other available networks, if searching other available networks then gets back to step 23, if do not search then execution in step 29 of other available networks;

Step 29: switch to another kind of RAT, new search RAT network and corresponding PLMN thereof lay equal stress on; Get back to step 23 afterwards;

Step 26:UE attempts the position renewal or registers this network;

Step 27: judge whether renewal or registration be successful, if then end of success; Otherwise execution in step 28;

Step 28: current PLMN sign and RAT network identity are recorded in the FPLMN table of expansion, afterwards, return execution in step 24.

Fig. 3 is another specific embodiment of accompanying method of the present invention.

Step 31: record of storage inserts, roams the PLMN of refusal and the form of the RAT network information separately in the subscriber identification module of mobile phone, is called for short access roaming refusal table, and is as shown in table 3:

Table 3

The enterprising line position of certain RAT network upgrade or during registration, 11 or 13 the message of receiving that network side returns, then that UE is current PLMN sign and RAT identification record are in table 1;

Step 32: 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 33: whether the PLMN that checks this RAT network correspondence is present in the FPLMN table, if exist, determines that then described PLMN forbids that this UE inserts, execution in step 34, otherwise, execution in step 35;

Step 34: 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 33; If do not search other available RAT networks, then execution in step 39;

Step 35: if not in FPLMN, continue to check described access roaming refusal table, i.e. table 1, if 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 36, otherwise, execution in step 34;

Step 36: allow UE to attempt this PLMN network of registration, and carry out corresponding position and upgrade;

Step 37: 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 38, if UE receives the message that the position is upgraded or succeeded in registration, then processing procedure finishes;

Step 38: PLMN sign and the current RAT network identity that will refuse access roaming record in the described access roaming refusal table, and no longer this PLMN are written among the FPLMN, and execution in step 34;

Step 39: 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 33 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.

In the present embodiment, for meeting the corresponding protocol requirement, if write down in the described access roaming refusal table certain PLMN the refusal record of all RAT of supporting of corresponding mobile phone, 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.

In in the present embodiment, 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 FPLMN and/or 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 by UE when manual registration is successful, revise described access roaming refusal table automatically.

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.
