Description
Technical field
The present invention relates to the processing method of urgent call, relate in particular to a kind of method and the method for handling called subscriber in the urgent call call-back and the method that the called subscriber handles urgent call of handling called subscriber in the urgent call.
Background technology
In the existing communication system, allow under the limited situation in some business or place, the calling subscriber also can dial 110,119 emergency numbers such as grade, thereby guarantees that the user can send SOS information to the external world in the very first time.
Dial the processing procedure of 110 policemen office phone with UE (User Equipment, subscriber equipment) A below for the existing urgent call of example introduction.
(1) UE A dials 110;
(2) CN (Core Network, core net) after the police office control centre in receives this emergency call, find its subordinate's a particular user equipment UE B (as the landline telephone of the office in police station inside or certain policeman's mobile phone) according to pre-defined algorithm, this urgent call is mapped to UE B.After this, ENODEB (enhancement mode Node B) distributing paging (paging) message of CN in LTE, described beep-page message carries out paging in order to indication ENODE B to UE B.
(3) ENODE B and then again to UE B distributing paging (paging) message;
(4) after UE B receives this paging, be refusal or allow this paging according to current oneself situation decision.
The reason of UE B refusal paging has multiple, for example, when system's excess load, page reply in order to limit, UE is at MM (Mobility Management, mobile management) layer variable " Paging Responseto CS Services Restriction " is set to limited, and then, the paging that UE B will refuse after this to receive.Again for example, system is if to certain when forbid professional or some sub-district, can issue the project of being under an embargo in system broadcast message, UE just stores then, will be stored by the taboo project by " inserting rank banned list Access ClassBarred list " mode.And then, refuse described all pagings of being prohibited project that relate to that it receives.Usually, will include but not limited to that the above-mentioned all the elements of project of forbidding plan as a whole to " special service inserts rank and forbids (SSACB, Service Specific Access Class Barring).Generally speaking, whether UE can refuse this paging according to the decision of SSACB content after ENODE B receives beep-page message.If this paging relates to the project of forbidding among the SSACB, then refuse this paging, no longer carry out follow-up access and handle; If this paging does not relate to the situation of forbidding among the SSACB, then allow this paging, continue to carry out follow-up access and handle, so that and calling UE A conversation with ENODE B.
(5), then initiate connection request, and then whether ENODEB allows this time to insert according to current system resource situation decision to ENODE B if UE B allows this paging.
UE B both can be the called subscriber of a urgent call, can be the called subscriber of an ordinary call too, and under the called situation when it calls out UE B as a UE C of domestic consumer (as the relatives of UE B), handling process is as follows:
(1) UE C dials the number of UE B
(2) core net CN is to ENODE B distributing paging (paging) message, and described beep-page message carries out paging in order to indication ENODE B to UE B.
After this handling process and the step in the urgent call (3) are identical to (5), repeat no more.
Contrast above-mentioned UE B equally as can be known as the handling process of called urgent call and ordinary call, CN is to the beep-page message of the paging UE B of ENODE B transmission, and the processes such as access connection between follow-up ENODE B and the UE B, be identical with regard to both.In other words, inserting side ENODE B treats equally to the called of called and ordinary call as urgent call, owing to exist in the access procedure and multiplely cause urgent call can't exhale logical possible situation, for example system's excess load etc. relates to the project of forbidding among the SSACB, therefore, can't guarantee that called in the urgent call has higher call completion ratio, and then make the caller in the urgent call can't in time obtain called relief.
In addition, after sometimes the user had dialed urgent call, the other side (such as the police) may hurry, so can get in touch a moment later again.After this, as the other side (police) when beating again, urgent call caller has before this just become called, i.e. called in the urgent call call-back, based on aforementioned same reason, can't guarantee that still called in the urgent call call-back has higher call completion ratio.
Summary of the invention
The problem that the embodiment of the invention will solve provides a kind of method of handling called subscriber in the urgent call, so that called in the urgent call can keep higher call completion ratio.The present invention also aims to the processing method that provides called in a kind of urgent call call-back, make called in the urgent call call-back can keep higher call completion ratio.

Embodiment
Below in conjunction with accompanying drawing, various embodiments of the present invention are done more detailed introduction.
See also Fig. 1, it handles the method first embodiment flow chart of called subscriber in the urgent call for the present invention.
The main thought of present embodiment is to increase a value emergency for the paging cause in paging (paging) message; In broadcast, increase an indication indication, whether allow MT EC to ignore SSACB (Service Specific Access Class Barring in order to indicate system, particular service inserts rank to be forbidden), convenient for following narration, this indication is called urgent permission indication; CM (Connection Management in UE (subscriber equipment) side, connection management) layer increases a variable " ignoreSSACB (ignoring SSACB) ", according to the urgent permission indication in the aforementioned broadcast this variable is set, and then whether indication MT EC (Mobile Terminating Emergency Call, the called subscriber in the urgent call) can ignore SSACB.
ENODEB in the step 110:LTE system (enhancement mode Node B) is to UE transmitting system broadcast, and increasing an indication in the described system broadcast message is aforesaid urgent permission indication.Need explanation, ENODEB described in the various embodiments of the present invention can also RNC be that (wireless network control) waits other access control nodes, in other words, access control node described in the technical solution of the present invention includes but not limited to ENODEB in the LTE system and the RNC in the UMTS system, for example can also be the BSC in the gsm system.
Step 120: the UE1 in the system receives the said system broadcast, according to the urgent permission indication in the system broadcast message variable " ignore (ignoring) SSACB " is set.
Allow MT EC to ignore SSACB if described urgent permission indicates system, UE is the variable of CM layer " ignore SSACB " set " MT EC ignores SSACB " just so, otherwise is this variable set " MT EC normally carries out SSACB ".
Step 130:Cn (Core Network, core net) receives a urgent call from UE 2, and it finds the phone of a free time according to some algorithm, be mapped to this phone, promptly on the MT EC UE 1, and then, the calling subscriber of urgent call this time is UE 2, and the called subscriber is UE 1.Then, issue paging message by ENODEB to UE1.Paging cause value in the described paging message is " emergency (promptly) ".
After step 140:UE1 receives paging message, carry out subsequent treatment according to variable " ignore SSACB " and pagingcause value.The detailed process of this step is please referring to sub-process A shown in Figure 2.
Substep S141:CM layer checks whether variable " ignore SSACB " equals " MT EC ignores SSACB ".If, execution in step S142 then; If not, then carry out substep S144.
Substep S142: check whether paging cause value equals " emergency ".If, execution in step S143 then; If not, execution in step S144 then.
Substep S143:MT EC ignores SSACB, directly inserts.Particularly, MT EC copies pagingcause (emergency) to and inserts in the reason, and comprises the access request message that inserts reason to ENODE B transmission.After this, carry out substep S145.Need explanation, also can not send the access reason when access is asked, it is former in urgent call to reinform this access of ENODEB after ENODEB allows MT EC to insert, and then ENODEB can give the priority higher with this access at aspects such as Resources allocation.
Substep S144:MT EC carries out SSACB as usual, carries out inserting identical processing with existing called subscriber, repeats no more.After this, carry out substep S145.
Substep S145:ENODE B judges whether system allows to insert.This step only in particular cases exists at some, and for example, no matter inserting reason is what, and ENODE B does not allow to insert.If system allows to insert, then carry out substep 146; If do not allow to insert, then finish access procedure.
Substep S146:ENODE B judges whether the access reason is " emergency ".If then carry out substep S147; If not, then carry out substep S148.
Substep S147:ENODE B gives with this and inserts the highest access service rank ASC (Accessservice classes) (as ASC0) of request, promptly allows it have higher-priority, directly inserts.If " normally " all thought in generation sub-district gravity treatment in emergency calling process, the sub-district in all these PLMN (PLMN), can gravity treatment.If current PLMN exceeds the situation of the area of coverage, UE1 can carry out the PLMN gravity treatment, to select other PLMN.For EC, network side thinks that all PLMN are " normally ", and is limited.
Substep S148:ENODEB handles according to the existing conventional access process, repeats no more.
See also Fig. 3, it handles the method first embodiment flow chart of called subscriber in the urgent call call-back for the present invention, called subscriber's method first embodiment in present embodiment and the aforementioned processing urgent call relates in paging on called subscriber's process of urgent call (urgent call or its callback) and has the similar techniques scheme.
ENODEB in the step 310:LTE system is to UE transmitting system broadcast, and described system broadcast message comprises aforesaid urgent permission indication, and whether described urgent permission indication allows MTEC to ignore SSACB in order to indicate system.
Step 320: the UE 2 in the system receives the said system broadcast, according to the urgent permission indication in the system broadcast message variable " ignore SSACB " is set.
Allow MT EC to ignore SSACB if described urgent permission indicates system, UE2 is the variable of CM layer " ignore SSACB " set " MT EC ignores SSACB " just so, otherwise is this variable set " MT EC does not ignore SSACB ".
Step 330:Cn handles the urgent call from UE2, and the callback of urgent call.Detailed process sees sub-process C shown in Figure 4 for details.
After substep S331:Cn receives urgent call from UE2, carry out the phone mapping according to some algorithm.
Particularly, if find the phone MT EC UE 1 of a free time, then directly carry out paging to it.If the MT EC that finds this moment is not idle, then CN gives called phone UE 1 special prompt tone or short message, whether cuts off present conversation by called own decision then connects urgent call.If conversation is at present cut off in called decision, directly switch in the urgent call; If present conversation is not cut off in called decision, then by called oneself decision callback (callback) whether a moment later.After this carry out substep S332.
Substep S332:CN writes down the caller of this urgent call and called corresponding relation (as the form of information table).For example, the calling subscriber who writes down this urgent call is UE2, and the called subscriber is UE1.The implementation of concrete corresponding relation has multiple, for example adopts corresponded manner of IMSI or EMSI or the like.If SIM (Subscriber Identity Module, User Recognition) card is arranged, just can carry out the corresponding relation of calling and called by IMSI (user ID), if there is not SIM card, can use EMSI (device identification) or other device identification number correspondences.In addition, can do a mark,, belong to the calling and called corresponding relation of urgent call to show described corresponding relation as " emergencySSACB " for this corresponding relation.Simultaneously, for timer of calling and called corresponding relation recording setting of described urgent call and start this timer, for with system in other timers distinguish mutually, be referred to as " urgent call call-back timer 1 ", can be set, such as 30 minutes the effective time of described timer 1 as required.If described " urgent call call-back timer 1 " surpasses the effective time of presetting, CN just deletes described corresponding relation record so.In addition, CN can also issue a message for the calling UE 2 of former urgent call by ENODEB, notice UE2 also starts a timer, for narrating unanimity, can be referred to as " urgent call call-back timer 2 ", " the urgent call call-back timer 2 " of described UE2 side keeps synchronously with " urgent call call-back timer 1 ", and the value that both are provided with is identical.Certainly, can also appoint the value of above-mentioned two timers in advance by user side and CN side, when UE2 initiates urgent call, just start described " urgent call call-back timer 2 ", perhaps trigger startup by other particular message.
Substep S333: when described " urgent call call-back timer 1 " is not overtime, a CN special number of discovery (such as the police office) has been initiated calling, so CN just removes to search the calling and called corresponding relation that is marked with " emergency SSACB " of substep S332 record.
Substep S334:CN judges according to the calling and called corresponding relation of the urgent call of record whether this calling is the callback of urgent call before this.If then carry out substep S335; If not, then carry out substep S336.For example, the calling of supposing described special number is to call out from UE1, its calling to as if UE2, so according among the substep S336 about the record of urgent call: the calling subscriber of urgent call is UE2, the called subscriber is UE1, can judge the callback of this calling for the urgent call of UE2 initiation before this, promptly the calling subscriber in the callback of the urgent call of aforementioned record is UE1, and the called subscriber is UE2.
Substep S335:CN issuing page message, this calling of indication is urgent call in the described beep-page message, particularly, the paging cause value in the paging message is " emergency ".
Substep S336:CN issues paging message by ENODEB to UE, and the paging cause value in the described paging message is " unknown (the unknown) " or " Terminating call " or " other non-emergency ".In other words, to the callback of non-emergency call, handle according to existing normal call, detailed process repeats no more.
After step 340:UE2 receives paging message, carry out subsequent treatment according to variable " ignore SSACB " and pagingcause value.The detailed process of this step is with the step 130 among the aforementioned embodiment and 140, and promptly UE2 can ignore SSACB, directly inserts, and the ENODEB that inserts side gives its highest access service rank.Thereby, guarantee that the called subscriber in the urgent call call-back can keep higher call completion ratio.In addition, in order to complete successfully the CALLBACK of urgent call, in " urgent call call-back timer 2 " time range, this UE can select any PLMN, resident any sub-district.If this PLMN is limited in the PLMN of UE2 tabulation, perhaps this sub-district is limited in the CELL tabulation, detects paging cause in the time of paging receiving, as long as this value is " emgergency ", just accepts this paging; Otherwise refuse this paging.If timer expiry, the selection of PLMN and CELL, resident all be to be undertaken by normal flow.
See also Fig. 5, it handles the method second embodiment flow chart of called subscriber in the urgent call for the present invention.Present embodiment adopted with the aforementioned processing urgent call in called subscriber's the method second embodiment similar techniques scheme.
Whether step 500:ENODEB/RNC allows called (the MT EC) of urgent call to ignore SSACB, can pass through O﹠amp; M or global variable etc. are provided with.The ENODEB of LTE (RNC of UMTS system) is provided with this variable " emergency SSACB " then.If require MT EC to ignore SSACB, this variable just is set is " MT EC ignores SSACB ", otherwise be set to " normal process SSACB "
Step 510:CN issues paging message to the ENODEB of LTE (RNC of UMTS system) after receiving a urgent call (called subscriber of this urgent call is the UE1 in police office), and wherein paging cause value is " emergency ".
Step 520:Enodeb receives paging message, checks variable " emergency SSACB ", if variate-value is " MT EC ignores SSACB ", it is " emergency " that the paging that then is handed down to UE1 just has paging cause value.Otherwise paging cause intermediate value is made as " unknown " or " other non-emergency ".
After step 530:UE1 receives this beep-page message, check paging cause,, directly insert if " emergency " then ignores SSACB.Otherwise, carry out normal access procedure.The idiographic flow of this step, identical with the substep S142 to S148 among method first embodiment of called subscriber in the aforementioned processing urgent call, so repeat no more.
See also Fig. 6, it handles the method second embodiment flow chart of called subscriber in the urgent call call-back for the present invention.
Whether step 600:ENODEB/RNC allows called (the MT EC) of urgent call to ignore SSACB, can pass through O﹠amp; M or global variable etc. are provided with.The ENODEB of LTE (RNC of UMTS system) is provided with this variable " emergency SSACB " then.If require MT EC to ignore SSACB, this variable just is set is " MT EC ignores SSACB ", otherwise be set to " normal process SSACB ".
Step 610:CN handles the urgent call from UE2, and from the urgent call call-back of UE1.If the callback of urgent call, then paging cause value is " emergency " in the beep-page message that ENODE issues, otherwise paging cause value is " unknown " or " Terminating call " or " other non-emergency " etc.The detailed process of this step is identical with the detailed process of abovementioned steps 330, sees sub-process C shown in Figure 4 for details, repeats no more herein.
Step 620:Enodeb receives paging message, checks variable " emergency SSACB ", if variate-value is " MT EC ignores SSACB ", it is " emergency " that the paging that then is handed down to UE2 just has paging cause value.Otherwise paging cause intermediate value is made as " unknown " or " Terminating call " or " other non-emergency ".
Whether step 630:UE2 is designated as urgent call according to the beep-page message of receiving is carried out subsequent treatment.Processing procedure of this step and the step 530 in the previous embodiment are identical, promptly receive beep-page message after, check paging cause, if " emergency " then ignores SSACB, directly insert.Otherwise, carry out normal access procedure.In addition, for the callback (CALLBACK) that can complete successfully urgent call, " the urgent call call-back timer 2 " that UE2 starts under according to the indication of CN side (other situations that also provide timer 2 to start among the substep S332, repeat no more herein) time range in, UE2 can select any PLMN, resident any sub-district.If this PLMN is limited in the PLMN of UE 2 tabulation, perhaps this sub-district is limited in the CELL tabulation, detects paging cause in the time of paging receiving, as long as this value is " emgergency ", just accepts this paging; Otherwise refuse this paging.If timer expiry, the selection of PLMN and CELL, resident all be to be undertaken by normal flow.
Handle two embodiment of method of called subscriber in the urgent call by aforementioned disclosed the present invention, and two embodiment of method of called subscriber can sum up and obtain in the processing urgent call call-back, ENODEB can notify the user whether to carry out to ignore SSACB operation by broadcast when it is called as urgent call, perhaps ENODEB controls voluntarily by global variable, whether the called subscriber in described urgent call to indicate this paging be urgent call, Cao Zuo purpose is like this, system can control called in the called or urgent call call-back in the urgent call and whether allow to ignore SSACB, when system does not allow to relate under the called SSACB of the ignoring situation of urgent call, just identical with the handling process of existing normal call.Those skilled in the art are to be appreciated that, called in the called or urgent call call-back during system also can default urgency calls out must be carried out and ignore SSACB and operate, in this case, ENODEB need not to notify the user whether to carry out to ignore SSACB operation by broadcast when it is called as urgent call, also need not ENODEB and whether decides the called subscriber in described urgent call (or callback) in its sole discretion to indicate this paging be urgent call.Particularly, need not " ignore SSACB " variable is set in UE, as long as this calling of indication is urgent call in the beep-page message that ENODEB issues, UE just carries out and ignores the SSACB operation so, on the contrary normal process SSACB; In like manner, also need not in ENODEB " emergency SSACB " variable is set, this is called out and is urgent call as long as CN issues in the beep-page message of ENODEB indication, and so, ENODEB indicates this to call out to the UE paging time to be urgent call too.More aforementioned each embodiment is more simple for this disposition, and please referring to Fig. 7, it handles method the 3rd embodiment flow chart of called subscriber in the urgent call for the present invention.
Step 700: if CN receives a urgent call, then issue paging message to the ENODEB of LTE (RNC of UMTS system), wherein paging cause value is " emergency "; Otherwise the paging cause value that issues is " non-emergency ".
Step 720:ENODEB is transmitted to UE after receiving paging message.If the paging cause value of ENODEB in the paging message that CN receives is " emergency ", the pagingcause value that then is handed down to the UE side also is " emergency "; Otherwise the paging cause value that is handed down to the UE side is " non-emergency ".
After step 730:UE receives this beep-page message, check paging cause,, directly insert if " emergency " then ignores SSACB.Otherwise, carry out normal access procedure.Introduced owing to done in detail among the aforementioned a plurality of embodiment of concrete processing procedure of this step, so locate to repeat no more.
Based on relating to the same inventive concept of a plurality of embodiment of method of called subscriber in the urgent call with aforementioned processing, the embodiment of the invention also discloses a kind of user-side device of handling urgent call, this device can be arranged in the various subscriber equipmenies, as landline telephone, mobile phone etc.See also Fig. 8, be the structural representation of user-side device embodiment of the present invention, simultaneously,, also provided access control node in the drawings with this device direct communication for clearer narration present embodiment device.In like manner, the access control node in the present embodiment includes but not limited to ENODEB, the RNC in the UMTS system in the LTE system and the BSC in the gsm system.Below in conjunction with the operation principle of this device, further disclose its internal structure.Certainly, owing to disclosed many identical or corresponding techniques features among aforementioned a plurality of method embodiment, therefore, only underdraw below.
At first by the beep-page message of receiving element 81 receptions from the access control node, the urgent call of being resolved from described beep-page message in paging reason or the beep-page message by message parse unit 82 is indicated then, urgent call indication in described paging reason or the beep-page message may be urgent call, it also may be non-emergency call, describe in detail about the particular content preamble of beep-page message is existing, so locate to repeat no more.
After message parse unit 82 parses urgent call indication in paging reason or the beep-page message, then transfer to and insert processing unit 83 and carry out subsequent treatment.Particularly, described access processing unit 83 comprises that subelement 831 is handled in urgent access and subelement 832 is handled in common access, if the indication of the urgent call in paging reason that message parse unit 82 parses or the beep-page message is not urgent call, then handle the subelement 832 normal SSACB of execution, carry out routine and insert by common access; If the indication of the urgent call in paging reason that message parse unit 82 parses or the beep-page message is urgent call, then handle subelement 831 and ignore SSACB by urgent access, directly insert to the access control node.With regard to subelement 831 is handled in urgent access, it specifically comprises access reason processing module again and inserts request processing module, wherein, to copy to as the urgent call of paging reason to insert to indicate in the reason or according to the urgent call in the beep-page message and set the access reason by inserting the reason processing module, and then send to comprise to the access control node and insert former because the access request of urgent call by inserting request processing module, the urgent call in the described access reason gives this time to insert the foundation of request highest priority as the access control node.In other words, the access control node inserts former because the highest access service rank of access request of urgent call gives this time access the highest priority, makes the callback of this urgent call or urgent call can exhale logical as far as possible.
Further, can also in inserting processing unit 83, control sub unit be set, whether be under an embargo by the urgent processing subelement that inserts of described control sub unit control, for example control by a global variable, the urgent permission indication of the value of this global variable in can system broadcast message is provided with (detailed content of this part is referring to preamble).If described urgent access processing subelement 831 is under an embargo (not allowing the called subscriber to ignore SSACB) as system, then paging reason that parses in message parse unit 82 or the urgent call in the beep-page message are designated as under the situation of urgent call, control sub unit will be controlled common access processing subelement 832 and replace the urgent processing subelement 831 that inserts to handle, in other words, in such cases, be urgent call though the paging information that the access control node issues indicates this to call out, user side is still handled as common paging.If described urgent access is handled subelement 831 and is not under an embargo, then paging reason that parses in message parse unit 82 or the urgent call in the beep-page message are designated as under the situation of urgent call, still handle subelement 831 by urgent access and carry out follow-up access processing.By above a plurality of specific embodiments as can be seen, in technical solution of the present invention, indicating this paging by the called subscriber in urgent call or urgent call call-back is urgent call, and the called subscriber ignores the operation that SSACB directly inserts, make described called subscriber no longer be subjected to the restriction of SSACB, have higher priority, therefore improved the call completion ratio of the paging that relates to urgent call, make stranded user to get help in the very first time.
Further, owing to relate to the called subscriber of urgent call when the access control node inserts, informed that access is former because urgent call, and then, the access control node is given with this and is inserted the highest access service rank of request, make this access request can preferentially obtain various Resources allocation, make the preferential connecting system of the called subscriber who relates to urgent call, thereby further guaranteed the call completion ratio of urgent call or its callback.
More than introduced method the 3rd embodiment that the present invention handles called subscriber in the urgent call, corresponding, the technical scheme of present embodiment is applicable to calling called subscriber in the callback process of urgent call too, repeats no more herein.
More than the method for called subscriber in processing urgent call provided by the present invention or the urgent call call-back and the method that the called subscriber handles urgent call are described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
