Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.

What deserves to be explained is, the technical scheme that the embodiment of the invention provides, go for various communication systems, such as long evolving system (Long Term Evolution, abbreviation LTE), Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short WCDMA) or global system for mobile communications (Global System for Mobile Communications is called for short GSM) etc.

Be understandable that HNB and sub-district have corresponding relation, if CSG is not supported in the HNB base station, then respective cell is the CSG sub-district.In the technical scheme of prior art, the access customer open service is only aimed in the CSG sub-district of Close pattern, but allows non-access user to carry out urgent call.HNB judges urgent call according to reason for call, if urgent call, then HNB/HNB GW does not do the access judgement, distributes Context ID also to allow user's communication.After non-access user's urgent call finished, because Context ID distributes, the user can not do access when carrying out other business again.

At the problems of the prior art, the invention provides various embodiments.

Embodiment one:

At above-mentioned technical problem, the embodiment of the invention provides a kind of call processing method, and as shown in Figure 1, this method comprises the steps:

Step 101: the user terminal UE that initiates urgent call for HNB down distributes context resource, allows this UE to carry out the urgent call conversation;

In this step, no matter whether UE is access UE, if its initiation is urgent call, all needs for this UE distributes context resource, and allows it to carry out the urgent call conversation.Wherein, the context distributed resource can be the context ID that sets up for this UE.

This context ID is the UE context ID, and as the contextual sign of UE, so that write down the UE context and discern UE, this context ID also is the signaling connection ID simultaneously.Under the HNB scene, when UE is for the first time resident, just distribute this context ID, follow-uply safeguard by ageing timer.

Step 102:, then after the urgent call of this UE finishes, be released to this UE context distributed resource if this UE is non-access user.

In the prior art,, just represent the resident mistake of UE, can not do access once more and judge if HNB/HNB gateway (Gateway is called for short GW) finds that UE has had Context ID.So, if according to the scheme of prior art, after non-access user's urgent call finishes, because Context ID distributes, the user can not do access when carrying out other business again, like this, just causes non-access user also can carry out professional situation in the CSG sub-district of Close pattern.

At this problem, the processing mode in this step is: after urgent call finishes, be released to the context ID that non-access user sets up, just discharge the UE context.

Concrete, can by HNB according to the sign of UE whether in the access tabulation, judge whether UE is non-access user; In judged result is under the situation that is, can initiate UE by HNB and remove register flow path, is released to UE context distributed resource (such as context ID).Perhaps, can by the HNB gateway according to the sign of UE whether in the access tabulation, judge whether UE is non-access user; In judged result is under the situation that is, initiates UE by the HNB gateway and removes register flow path, is released to UE context distributed resource (such as context ID).

Further, can also comprise: judge whether the calling that UE initiates is urgent call, and whether UE is non-access user; If what UE initiated is not urgent call, and UE is non-access user, then refuses UE and initiates this calling.

Description by this embodiment owing to after urgent call finishes, discharged non-access user's context resource, has prevented that non-access user from utilizing urgent call to initiate unallowed business, thereby has improved the fail safe of access control as can be known.

Embodiment two:

Below in conjunction with Fig. 2, the call processing method that present embodiment two is provided is described in detail, and among this embodiment, the network element that relates to comprises: UE, HNB, HNB GW and core net (Core network is called for short CN).

After the resident HNB of the step 201:UE sub-district, set up RRC with HNB and be connected;

In this step, UE and HNB set up radio resource control (Radio Resources Control is called for short RRC) and connect.Set up in the process at RRC, UE can carry UE identification information UE identity, UE ability information UE capabilities, sets up information such as cause value Establishment Cause and gives HNB.This sets up cause value can represent whether this calling is urgent call.

Concrete, UE can connect Non-Access Stratum of initiation (Non-AccessStadium is called for short NAS) flow process by setting up RRC, such as, location area updating (Location Area Update is called for short LAU) flow process.

After step 202:RRC set up, UE initiated the RRC direct-sending message;

In this step, the RRC direct-sending message can be RRC initial direct-sending Initial Direct Transfer message, in this RRC initial direct-sending message, and the sign that can carry UE.This RRC initial direct-sending message can be location update request message Location Updating Request message.

Step 203:HNB checks the UE ability that gets access in the step 201;

In this step, HNB checks the UE ability that gets access in the step 201, if UE does not support CSG, then adopts non-CSG access, and non-CSG access is carried out at Access Network (HNB GW/HNB).

If the context ID of this UE not among this HNB, then execution in step 205, and HNB is initiated to the UE register flow path of HNBGW, and this register flow path can be supported the distribution of Context ID, so that record UE context and discern UE.

In addition, optionally, before initiating this UE register flow path, HNB can judge earlier whether UE sets up at RRC and report identification information in the process.This identification information can be international mobile subscriber identity (international mobile subscriber identity, being called for short IMSI) information or other can discern the identification information of UE, such as temporarily moved subscriber identification (Temporary Mobile SubscriberIdentity, be called for short TMSI), but mainly being example with IMSI, the embodiment of the invention is described.If HNB judges that UE does not set up at RRC and do not report IMSI in the process, and be not the urgent call flow process, then HNB initiates to obtain the Identity process of IMSI to UE, to obtain its IMSI.

If there has been the context ID of this UE among this HNB, then can not trigger the UE register flow path.

Step 204: if HNB enables auxiliary access, HNB can carry out the access control based on IMSI;

This step is optional, and is concrete, and HNB whether in the access tabulation, judges whether to allow the UE access according to the IMSI of UE; Need to prove that if the reason for call value in the RRC connection request is urgent call, then HNB does not just do the access judgement, directly allows the access of this UE;

Step 205:HNB is initiated to the UE register flow path of HNB GW;

In this step, HNB initiates the UE register flow path to HNB GW, sends UE register requirement UE REGISTER REQUEST message for HNB GW.Can carry UE Identity (such as IMSI), UE ability information in this message and set up information such as cause value Establishment Cause.

Step 206:HNB GW does access control to UE;

In this step, HNB GW can judge whether to allow the UE access according to the IMSI of UE whether in the access tabulation; Need to prove that if what set up that cause value shows that UE initiates is urgent call, then HNB GW does not just do access and judges, promptly directly allows the access of this UE, accepts the register requirement of this UE.

Step 207:HNB GW accepts the UE register requirement, distributes context ID to UE;

In this step, be example with the urgent call, under this kind scene, HNB GW accepts the UE register requirement, distributes Context ID context ID to UE, and replys registration to HNB and accept message HNBAPUE REGISTER ACCEPT message, and this message kind comprises context ID.

Be understandable that, if HNB GW refusal UE register requirement is then replied registration reject message HNBAP UE REGISTER REJECT message to HNB.

After step 208:HNB receives that message is accepted in the registration of HNB GW, initiate RUA CONNECT message;

In this step, HNB initiates adaptive (the RANAP User Adaption of RANAP user, be called for short RUA) CONNECT message, wherein, can comprise Radio Access Network Application Part (Radio Access Network Application Part is called for short RANAP) InitialUE message among this RUA CONNECT.

Step 209:HNB GW receives RUA CONNECT message, and sets up SCCP (Signalling Connection control Part is called for short SCCP) connection between the CN, and transmits RANAP Initial UE message to CN;

Step 210:CN response SCCP connects affirmation;

Continue the NAS flow process between step 211:UE and the CN.

Step 212: urgent call is initiated UE for non-access user and is removed register flow path after finishing, and discharges Context ID.

In this step,, non-access user is initiated UE remove register flow path according to user's access situation (, adjudicating) if do not do then whether belong to the access tabulation according to the IMSI of UE if done access control then with reference to the access result.

It can be HNB GW that initiation UE goes the main body of register flow path, perhaps, if HNB is access control HNB, also can be to be initiated by HNB.Be understandable that,,, also can do same processing, promptly initiate UE and remove register flow path, discharge Context ID owing to can be considered as non-access user for the user who obtains less than IMSI.

As previously mentioned,, just represent the resident mistake of UE, can not do access once more and judge, provide possibility for non-access user initiates unallowed business because if HNB/HNB GW finds that UE has had Context ID.Therefore, the technical scheme of the embodiment of the invention, for the urgent call scene, consider the needs of fail safe, finish back initiation UE in urgent call and remove register flow path, discharge Context ID, can improve the fail safe of CSG sub-district access control, prevent that non-access user (disabled user) from utilizing urgent call to initiate unallowed business.

Concrete, the embodiment of the invention also provides multiple implementation, to realize that UE removes register flow path, is described below in conjunction with accompanying drawing.

As shown in Figure 3, be the schematic diagram that the UE that is initiated by HNB that the embodiment of the invention provides removes register flow path.

This flow process comprises: HNB removes to register the message initiated UE of DE-REGISTER by transmission UE and removes register flow path.When receiving that UE removes registration message, HNB GW should discharge all relevant resources of this UE, comprises Context ID.

As shown in Figure 4, be the schematic diagram that the UE that is initiated by HNB that the embodiment of the invention provides removes register flow path.

This flow process comprises: HNB GW removes register flow path by sending the message initiated UE of UE DE-REGISTER.When receiving that UE removes registration message, HNB should discharge all relevant resources of this UE, comprises Context ID.

Be understandable that the implementation by the multiple UE that provides removes register flow path can adapt to different application scenarioss, make that the realization of embodiment of the invention scheme is more flexible.

Embodiment three:

At problems of the prior art, the embodiment of the invention also provides another implementation method, as shown in Figure 5, comprising:

501: judge whether the calling that the user equipment (UE) under the Home eNodeB HNB is initiated is urgent call, and judge whether this UE is non-access user;

502: if this UE initiates is not urgent call, and this UE is non-access user, then refuses UE and initiates this calling.

Concrete, can judge the UE access customer that whether is as the criterion in the following manner, HNB whether in the access tabulation (access is tabulated can be configured in the HNB place), judges whether this UE is non-access user according to the sign of UE; Or the HNB gateway whether in the access tabulation (access is tabulated can be configured in HNB GW place), judges whether this UE is non-access user according to the sign of UE.

Further, after judging whether calling that UE initiates is urgent call, can also comprise: check whether the emergency telephone number that UE initiates is illegal, if this emergency telephone number is illegal, and this UE is non-access user, then refuses UE and initiates this calling.

As seen, the technical scheme that the embodiment of the invention provides, by when making a call, the correctness of urgent call flow process being judged, if what this UE initiated is not that urgent call and this UE are non-access user, refuse this UE and initiate this calling, by such mechanism of permitting the entrance, can prevent that non-access user from utilizing urgent call to initiate unallowed business, improved the fail safe of access control.

Embodiment four:

At problems of the prior art, the embodiment of the invention also provides another implementation method, below specifically 6 is described in conjunction with the accompanying drawings.This method comprises:

Step 601-602:UE sets up RRC with HNB and is connected, and UE sends the RRC initial direct-sending message to HNB;

In the present embodiment, suppose the former because urgent call of setting up in the RRC connection request, suppose that perhaps the RRC initial direct-sending message is connection management (Connection Management, be called for short CM) service request information CM Service Request, and setting up among this CM Service Request is former in urgent call, HNB/HNB GW does not just do the access judgement so, promptly directly allows the access of this UE.

As previously mentioned, if adopt scheme of the prior art, if that then follow-up UE initiation is CallSetup, rather than Emergency Call Setup, will cause potential safety hazard.

Step 603-610: the corresponding steps of embodiment of the invention step 603-610 and previous embodiment is similar substantially, is not described in detail.What deserves to be explained is that the CN network element describes for example with mobile switching centre's (Mobile Switching Centre is called for short MSC) in the embodiment of the invention.

Optionally, can also comprise authorizing procedure and safe mode control flow, not shown.

Step 611:UE is by the foundation that makes a call of NAS message;

In this step, this NAS message can be Call Setup message.

Step 612: the correctness of checking urgent call flow process;

Be understandable that this step both can be carried out by HNB, also can carry out by HNB GW.

Concrete, for the urgent call of satisfying non-CSG entry criteria, check whether NAS message is Emergency Call Setup.If not Emergency Call Setup, and the user does not have access (if done access control then with reference to the access result, adjudicated if do not do then whether belong to the access tabulation) according to the IMSI of UE, then show and do not meet the urgent call flow process, refusal is initiated this calling, execution in step 613.

Optionally, can also check further also whether emergency telephone number is legal.If emergency telephone number illegal (promptly do not belong to the emergency telephone number tabulation that government allows, this tabulation can be pre-configured on the HNB/HNB GW), and the user does not have access, then this calling of refusal initiation, execution in step 613.

In addition, for the user who obtains less than IMSI, also can be considered as non-access user and handle equally.

Optionally, after execution in step 612, the prompting user that can also send SMS message, such as, the calling of pointing out this UE to initiate is rejected.

Step 613: disconnect connection and discharge related resource.

This step 613 specifically can be by discharging the flow process realization by calling out.It should be noted that discharging flow process is not limited in following giving an example.

Specifically can comprise: in the calling procedure, HNB/HNB GW determines to initiate to discharge; HNB/HNBGW sends descending direct-sending message (such as Release Complete) and gives UE, discharges mobile management (Mobility Management is called for short MM) and connects; HNB/HNB GW sends direct-sending message (such as CM Service Abort) and gives MSC, discharges MM and connects; MSC sends Iu Release Command message, discharges the Iu link; HNB returns Iu Release Complete message and gives MSC; HNB sends RRC Connect Release Request message to UE, discharges the RRC link; UE returns RRCConnect Release Complete message, finishes release.

The technical scheme that the embodiment of the invention provides, even because UE initiates urgent call and given access, but follow-up UE needs to check its urgent call flow process correctness making a call when setting up before, if do not meet the urgent call flow process, then refusal is initiated this calling.Guarantee to avoid non-access user to utilize urgent call and initiate unallowed business with this, improved the fail safe of access control.

Further, can also further check the legitimacy of its emergency telephone number, avoid utilizing illegal emergency telephone number to insert.

Be understandable that the multiple implementation that the embodiment of the invention provides both can independently exist, also can combine realization to solve the problems of the prior art.

Such as, UE user makes a call in HNB, and HNB/HNB GW checks its urgent call flow process correctness, optionally, can further verify the legitimacy of its emergency telephone number, if inspection is not passed through, then refuses UE and initiates this time to call out.And after call out discharging, HNB/HNB GW can check UE user's access customer that whether is as the criterion, and if not the access user, then discharges its Context ID.

Like this, both can when making a call, be checked, and can further finish the back again and discharge Context ID, can be guaranteed the fail safe of access control more fully in urgent call, avoid non-access user to initiate unallowed business, maintaining network safety and operator's interests.

Embodiment five:
