The invention discloses a method for processing the called user in the callback of the emergency call, a method for processing the emergency call by the called user and a user side device for processing the emergency call. Through the technical proposal provided by the invention, a call completion ratio concerning the emergency call is improved.
Description
Technical field
The present invention relates to the processing method of urgent call, relate in particular to a kind of method of processing called subscriber in urgent call and process the method for called subscriber in urgent call call-back and called subscriber processes the method for urgent call.
Background technology
In existing communication system, allow in some business or place limited in the situation that, calling subscriber also can dial 110,119 emergency numbers such as grade, thereby ensures that user can send in the very first time SOS information to the external world.
Dialing 110 policemen office phone with UE (User Equipment, subscriber equipment) A is below the processing procedure that example is introduced existing urgent call.
(1) UE A dials 110;
(2) CN (Core Network, core net) in police office control centre receive after this emergency call, a particular user equipment UE B (as the landline telephone of the office in police station inside or certain policeman's mobile phone) who finds its subordinate according to pre-defined algorithm, is mapped to UE B by this urgent call.After this, CN is to ENODEB (enhancement mode Node B) distributing paging (paging) message in LTE, and described beep-page message is in order to indicate ENODE B to carry out paging to UE B.
(3) ENODE B and then again to UE B distributing paging (paging) message;
(4) UE B receives after this paging, according to current oneself situation determine be refusal or allow this paging.
The reason of UE B refusal paging has multiple, for example, in the time of system 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 when forbidding certain business or some community, can in system broadcast message, issue the project of being prohibited, then UE just stores, and by " access rank banned list Access ClassBarred list " mode, banned project is stored.And then, refuse all pagings that relate to described banned project that it receives.Typically, will include but not limited to that above-mentioned all the elements pool of forbidding project is for " special service access rank is forbidden (SSACB, Service Specific Access Class Barring).Generally speaking, UE receives after beep-page message from ENODE B, can determine whether to refuse this paging according to SSACB content.If this paging relates to the project of forbidding in SSACB, refuse this paging, no longer carry out follow-up access processing; If this paging does not relate to the situation of forbidding in SSACB, allow this paging, continue to carry out follow-up access processing with ENODE B, so that and calling UE A call.
(5), if UE B allows this paging, initiate connection request to ENODE B, and then ENODEB determines whether to allow this time access according to current system resource situation.
UE B can be both the called subscriber of a urgent call, can be the called subscriber of an ordinary call too, and in the called situation in the time that 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 is in order to indicate ENODE B to carry out paging to UE B.
After this handling process is identical to (5) with the step (3) in urgent call, repeats no more.
Contrast above-mentioned UE B known as the handling process of called urgent call and ordinary call equally, the beep-page message of the paging UE B that CN sends to ENODE B, and the process such as access connection between follow-up ENODE B and UE B, with regard to both, be identical.In other words, access side ENODEB treats equally to the called of called and ordinary call as urgent call, owing to there being the multiple possible situation that causes urgent call to call through in access procedure, such as system excess load etc. relates to the project of forbidding in SSACB, therefore, cannot ensure that called in urgent call has higher call completion ratio, and then make the caller in urgent call cannot obtain in time called relief.
In addition, sometimes user has dialed after urgent call, and the other side (such as police) may hurry, so can contact a moment later again.After this, in the time that the other side (police) beats again, urgent call caller before this has just become called, i.e. called in urgent call call-back, based on aforementioned same reason, still cannot ensure that called in urgent call call-back has higher call completion ratio.
Summary of the invention

Embodiment
Below in conjunction with accompanying drawing, various embodiments of the present invention are done to more detailed introduction.
Refer to Fig. 1, it processes method the first embodiment flow chart of called subscriber in urgent call for the present invention.
The main thought of the present embodiment is to increase a value emergency for the paging cause in paging (paging) message; In broadcast, increase an indication instruction, whether allow MT EC to ignore SSACB (Service Specific Access Class Barring in order to indicate system, particular service access rank is forbidden), for narrating conveniently, this instruction is called to urgent permission instruction below; At CM (the Connection Management of UE (subscriber equipment) side, connection management) a layer variable of increase " ignoreSSACB (ignoring SSACB) ", according to the urgent permission instruction in aforementioned broadcast, this variable is set, and then whether instruction MT EC (Mobile Terminating Emergency Call, the called subscriber in urgent call) can ignore SSACB.
ENODEB (enhancement mode Node B) in step 110:LTE system is to UE transmitting system broadcast, and in described system broadcast message, increasing an instruction is aforesaid urgent permission instruction.Need explanation, ENODEB described in various embodiments of the present invention can also RNC be other access control nodes such as (wireless network control), in other words, access control node described in technical solution of the present invention includes but not limited to the RNC in ENODEB and the UMTS system in LTE system, for example, can also be the BSC in gsm system.
Step 120: the UE1 in system receives said system broadcast, arranges variable " ignore (ignoring) SSACB " according to the urgent permission instruction in system broadcast message.
Allow MT EC to ignore SSACB if described urgent permission indicates system, UE is just " MT EC ignores SSACB " the variable of CM layer " ignoreSSACB " set so, otherwise is " MT EC normally carries out SSACB " this variable set.
Step 130:Cn (Core Network, core net) receives a urgent call from UE2, and it finds an idle phone according to some algorithm, be mapped to this phone, on MT EC UE1, and then, the calling subscriber of this time urgent call is UE2, and called subscriber is UE1.Then, issue paging message by ENODEB to UE1.Paging cause value in described paging message is " emergency (promptly) ".
Step 140:UE1 receives after paging message, carries out subsequent treatment according to variable " ignore SSACB " and pagingcause value.The detailed process of this step please refer to the sub-process A shown in Fig. 2.
Sub-step S141:CM layer checks whether variable " ignore SSACB " equals " MT EC ignores SSACB ".If so, perform step S142; If not, carry out sub-step S144.
Sub-step S142: check whether paging cause value equals " emergency ".If so, perform step S143; If not, perform step S144.
Sub-step S143:MT EC ignores SSACB, directly accesses.Particularly, MT EC copies pagingcause (emergency) in access reason to, and sends and comprise the access request message that accesses reason to ENODE B.After this, carry out sub-step S145.Need to illustrate, also can in the time of access request, not send access reason, can after ENODEB allows MT EC access, reinform this access of ENODEB former in urgent call, and then ENODEB can give at aspects such as Resources allocation the priority higher with this access.
Sub-step S144:MT EC carries out SSACB as usual, carries out accessing identical processing with existing called subscriber, repeats no more.After this, carry out sub-step S145.
Sub-step S145:ENODE B judges whether system allows access.This step only in particular cases exists at some, and for example, no matter accessing reason is what, and ENODE B does not allow access.If system allows access, carry out sub-step 146; If do not allow access, finish access procedure.
Sub-step S146:ENODE B judges whether access reason is " emergency ".If so, carry out sub-step S147; If not, carry out sub-step S148.
Sub-step S147:ENODE B gives the access service rank ASC (Accessservice classes) (as ASC0) the highest with this access request, allows it have higher-priority, directly access.If there is cell reselection in emergency calling process, all these PLMN (PLMN) Nei thinks community " normally ", can gravity treatment.Exceed the situation of the area of coverage if there is current PLMN, UE1 can carry out PLMN gravity treatment, to select other PLMN.For EC, network side thinks that all PLMN are " normally ", limited.
Sub-step S148:ENODEB processes according to existing conventional access process, repeats no more.
Refer to Fig. 3, it processes method the first embodiment flow chart of called subscriber in urgent call call-back for the present invention, method the first embodiment of called subscriber in the present embodiment and aforementioned processing urgent call, relates in paging in called subscriber's process of urgent call (urgent call or its callback) and has similar technical scheme.
ENODEB in step 310:LTE system is to UE transmitting system broadcast, and described system broadcast message comprises aforesaid urgent permission instruction, and whether described urgent permission instruction allows MTEC to ignore SSACB in order to indicate system.
Step 320: the UE2 in system receives said system broadcast, arranges variable " ignore SSACB " according to the urgent permission instruction in system broadcast message.
Allow MT EC to ignore SSACB if described urgent permission indicates system, UE2 is just " MT EC ignores SSACB " the variable of CM layer " ignoreSSACB " set so, otherwise is " MT EC does not ignore SSACB " this variable set.
Step 330:Cn processes the urgent call from UE2, and the callback of urgent call.The detailed sub-process C as shown in Figure 4 of detailed process.
Sub-step S331:Cn receives after the urgent call from UE2, carries out phone mapping according to some algorithm.
Particularly, if find an idle phone MT EC UE1, directly carry out paging to it.If the MT EC finding is now not idle, whether CN, to the special prompt tone of called phone UE1 or short message, cuts off current call then connection urgent call by called own decision.If call is at present cut off in called decision, directly switch in urgent call; If current call is not cut off in called decision, oneself determine callback (callback) whether a moment later by called.After this carry out sub-step S332.
Sub-step S332:CN records the caller of this urgent call and called corresponding relation (as the form of information table).For example, the calling subscriber who records this urgent call is UE2, and called subscriber is UE1.The implementation of concrete corresponding relation has multiple, for example, adopt corresponded manner of IMSI or EMSI etc.If there is SIM (Subscriber Identity Module, user's identification) card, just can carry out the corresponding relation of calling and called by IMSI (user ID), if there is no SIM card, can use EMSI (device identification) or other device identification number correspondences.In addition, can do a mark for this corresponding relation, as " emergencySSACB ", to show that described corresponding relation belongs to the calling and called corresponding relation of urgent call.Simultaneously, for the calling and called corresponding relation record of described urgent call arranges a timer and starts this timer, for with system in other timers distinguish, be referred to as " urgent call call-back timer 1 ", can be set as required, such as 30 minutes the effective time of described timer 1.If described " urgent call call-back timer 1 " exceedes preset effective time, CN just deletes described corresponding relation record so.In addition, CN can also issue a message to the calling UE 2 of former urgent call by ENODEB, notice UE2 also starts a timer, consistent for narrating, can be referred to as " urgent call call-back timer 2 ", " the urgent call call-back timer 2 " of described UE2 side keeps synchronizeing with " urgent call call-back timer 1 ", and the value that both arrange is identical.Certainly, can also be appointed in advance the value of above-mentioned two timers by user's side and CN side, in the time that UE2 initiates urgent call, just start described " urgent call call-back timer 2 ", or trigger and start by other particular message.
Sub-step S333: in the time that described " urgent call call-back timer 1 " is not overtime, a CN special number of discovery (such as 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 sub-step S332 record.
Sub-step S334:CN, according to the calling and called corresponding relation of the urgent call of record, judges whether this calling is the callback of urgent call before this.If so, carry out sub-step S335; If not, carry out sub-step S336.For example, the calling of supposing described special number is to call out from UE1, its calling to as if UE2, so according to the record about urgent call in sub-step S336: the calling subscriber of urgent call is UE2, called subscriber is UE1, can judge this calling is the callback of the urgent call that UE2 initiates before this, and the calling subscriber in the callback of the urgent call of aforementioned record is UE1, and called subscriber is UE2.
Sub-step S335:CN issuing page message, indicates this to call out as urgent call in described beep-page message, particularly, the paging cause value in paging message is " emergency ".
Sub-step S336:CN issues paging message by ENODEB to UE, and the Paging cause value in described paging message is " unknown (the unknown) " or " Terminating call " or " other non-emergency ".Melt it, to the callback of non-emergency call, according to existing normal call processing, detailed process repeats no more.
Step 340:UE2 receives after paging message, carries out subsequent treatment according to variable " ignore SSACB " and pagingcause value.The detailed process of this step is with the step 130 in previous embodiment and 140, and UE2 can ignore SSACB, directly accesses, and the ENODEB of access side gives its highest access service rank.Thereby, ensure that the called subscriber in urgent call call-back can keep higher call completion ratio.In addition, in order to be successfully completed the CALLBACK of urgent call, in " urgent call call-back timer 2 " time range, this UE can select any PLMN, resident any community.If this PLMN is limited in the PLMN of UE2 list, or be limited in CELL list Zhong Gai community, when paging receiving, detect Paging cause, as long as this value is " emgergency ", just accept this paging; Otherwise refuse this paging.If timer expiry, the selection of PLMN and CELL, resident be all to be undertaken by normal flow.
Refer to Fig. 5, it processes method the second embodiment flow chart of called subscriber in urgent call for the present invention.The present embodiment adopted with aforementioned processing urgent call in called subscriber's the similar technical scheme of method the second embodiment.
Whether step 500:ENODEB/RNC allows called (the MT EC) of urgent call to ignore SSACB, can arrange by O & M or global variable etc.Then the ENODEB of LTE (RNC of UMTS system) arranges this variable " emergency SSACB ".If require MT EC to ignore SSACB, this variable is just set for " MT EC ignores SSACB ", otherwise is set to " normal process SSACB "
Step 510:CN receives after a urgent call (called subscriber of this urgent call is the UE1 in police office), ENODEB (RNC of UMTS system) to LTE issues paging message, 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 ", the paging that is handed down to UE1 is just " emergency " with paging cause value.Otherwise paging cause intermediate value is made as " unknown " or " other non-emergency ".
Step 530:UE1 receives after this beep-page message, checks paging cause, if " emergency " ignores SSACB, directly accesses.Otherwise, carry out normal access procedure.The idiographic flow of this step, identical with the sub-step S142 to S148 in method the first embodiment of called subscriber in aforementioned processing urgent call, therefore repeat no more.
Refer to Fig. 6, it processes method the second embodiment flow chart of called subscriber in 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 arrange by O & M or global variable etc.Then the ENODEB of LTE (RNC of UMTS system) arranges this variable " emergency SSACB ".If require MT EC to ignore SSACB, this variable is just set for " MT EC ignores SSACB ", otherwise is set to " normal process SSACB ".
Step 610:CN processes from the urgent call of UE2, and from the urgent call call-back of UE1.If the callback of urgent call, in the beep-page message issuing to ENODE, paging cause value is " emergency ", 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, and detailed sub-process C as shown in Figure 4 repeats no more herein.
Step 620:Enodeb receives paging message, checks variable " emergency SSACB ", if variate-value is " MT EC ignores SSACB ", the paging that is handed down to UE2 is just " emergency " with 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.Step 530 in processing procedure and the previous embodiment of this step is identical, receives after beep-page message, checks paging cause, if " emergency " ignores SSACB, directly accesses.Otherwise, carry out normal access procedure.In addition, in order to be successfully completed the callback (CALLBACK) of urgent call, " urgent call call-back timer 2 " (other situations that also provide timer 2 to start in sub-step S332 that UE2 starts under indicating according to CN side, repeat no more herein) time range in, UE2 can select any PLMN, resident any community.If this PLMN is limited in the PLMN of UE2 list, or be limited in CELL list Zhong Gai community, when paging receiving, detect paging cause, as long as this value is " emgergency ", just accept this paging; Otherwise refuse this paging.If timer expiry, the selection of PLMN and CELL, resident be all to be undertaken by normal flow.
Process two embodiment of method of called subscriber in urgent call by aforementioned disclosed the present invention, and in processing urgent call call-back, two embodiment of method of called subscriber can sum up and obtain, ENODEB can notify user whether to carry out in the time that it is called as urgent call to ignore SSACB operation by broadcast, or ENODEB controls voluntarily by global variable, whether indicating this paging to the called subscriber in described urgent call is urgent call, the object of operation is like this, system can be controlled called in the called or urgent call call-back in urgent call and whether allow to ignore SSACB, when system does not allow to relate in 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 of system in also can default urgency calling out must be carried out and ignore SSACB and operate, in this case, ENODEB is without notifying user whether to carry out in the time that it is called as urgent call to ignore SSACB operation by broadcast, also whether decide without ENODEB that to indicate this paging to the called subscriber in described urgent call (or callback) be urgent call in its sole discretion.Particularly, in UE, without " ignore SSACB " variable is set, as long as indicate this to call out as urgent call in the beep-page message that ENODEB issues, UE just carries out and ignores SSACB operation so, on the contrary normal process SSACB; In like manner, also without " emergency SSACB " variable is set in ENODEB, indicate this to call out as urgent call as long as CN issues in the beep-page message of ENODEB, so, ENODEB indicates too this to call out as urgent call when to UE paging.More aforementioned each embodiment is more simple for this disposition, please refer to Fig. 7, and it processes method the 3rd embodiment flow chart of called subscriber in urgent call for the present invention.
Step 700: if CN receives a urgent call, issue paging message to the ENODEB (RNC of UMTS system) of LTE, wherein paging cause value is " emergency "; Otherwise the paging cause value issuing is " non-emergency ".
Step 720:ENODEB receives after paging message, is transmitted to UE.If the paging cause value in the paging message that ENODEB receives from CN is " emergency ", the pagingcause value that is handed down to UE side is also " emergency "; Otherwise the paging cause value that is handed down to UE side is " non-emergency ".
Step 730:UE receives after this beep-page message, checks paging cause, if " emergency " ignores SSACB, directly accesses.Otherwise, carry out normal access procedure.In the aforementioned multiple embodiment of concrete processing procedure due to this step, did in detail and introduced, so locate to repeat no more.
Based on relating to the same inventive concept of the multiple embodiment of method of called subscriber in urgent call with aforementioned processing, the embodiment of the invention also discloses a kind of user-side device of processing urgent call, this device can be arranged in various subscriber equipmenies, as landline telephone, mobile phone etc.Referring to Fig. 8, is the structural representation of user-side device embodiment of the present invention, meanwhile, for clearer narration the present embodiment device, has also provided in the drawings the access control node with this device direct communication.In like manner, the access control node in the present embodiment includes but not limited to RNC in ENODEB, the UMTS system in LTE system and the BSC in gsm system.Below in conjunction with the operation principle of this device, further disclose its internal structure.Certainly,, owing to disclosing many identical or corresponding technical characterictics in aforementioned multiple embodiments of the method, therefore, only underdraw below.
First receive the beep-page message from access control node by receiving element 81, the urgent call of then being resolved in paging reason or beep-page message from described beep-page message by message parse unit 82 is indicated, urgent call instruction in described paging reason or beep-page message may be urgent call, also may be non-emergency call, about particular content existing detailed description the in detail above of beep-page message, so locate to repeat no more.
After message parse unit 82 parses the urgent call instruction in paging reason or beep-page message, transfer to access processing unit 83 and carry out subsequent treatment.Particularly, described access processing unit 83 comprises that subelement 831 is processed in urgent access and subelement 832 is processed in common access, if the instruction of the urgent call in the paging reason that message parse unit 82 parses or beep-page message is not urgent call, process the normal SSACB of execution of subelement 832 by common access, carry out routine access; If the instruction of the urgent call in the paging reason that message parse unit 82 parses or beep-page message is urgent call, process subelement 831 by urgent access and ignore SSACB, directly access to access control node.With regard to subelement 831 is processed in urgent access, it specifically comprises again access reason processing module and access request processing module, wherein, access in reason or indicate to set access reason according to the urgent call in beep-page message copying to as the urgent call of paging reason by access reason processing module, and then send and comprise the former access request because of urgent call of access to access control node by access request processing module, the urgent call in described access reason gives the foundation of this access request highest priority as access control node.In other words, access control node accesses former because the highest access service rank of access request of urgent call gives the highest priority of access this time, and the callback of this urgent call or urgent call can be called through as far as possible.
Further, can also in access processing unit 83, control subelement be set, whether promptly access processing subelement by the control of described control subelement is prohibited, for example control by a global variable, the urgent permission instruction of the value of this global variable in can system broadcast message arranges (detailed content of this part is referring to above).If described urgent access is processed subelement 831 and is prohibited (ignoring SSACB as system does not allow called subscriber), urgent call in paging reason or the beep-page message parsing in message parse unit 82 is designated as urgent call, control subelement will be controlled common access processing subelement 832 and replace urgent access processing subelement 831 to process, in other words, in such cases, although the paging information that access control node issues indicates this to call out as urgent call, user's side is still as common paging processing.If described urgent access is processed subelement 831 and is not prohibited, urgent call in paging reason or the beep-page message parsing in message parse unit 82 is designated as urgent call, still processes subelement 831 by urgent access and carries out follow-up access processing.Can find out by above multiple specific embodiments, 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 called subscriber ignores the operation that SSACB directly accesses, make described called subscriber no longer be subject to the restriction of SSACB, there is higher priority, therefore improved the call completion ratio of the paging that relates to urgent call, stranded user can be got help in the very first time.
Further, because the called subscriber who relates to urgent call is in the time accessing to access control node, inform that access is former because urgent call, and then, access control node is given the access service rank the highest with this access request, make this access request can preferentially obtain various Resources allocation, make to relate to called subscriber's priority access system of urgent call, thereby further ensured the call completion ratio of urgent call or its callback.
More than introduced method the 3rd embodiment that the present invention processes called subscriber in urgent call, corresponding, the technical scheme of the present embodiment is applicable to calling called subscriber in the callback process of urgent call too, repeats no more herein.
The method that method to called subscriber in processing urgent call provided by the present invention or urgent call call-back and called subscriber process urgent call is above described in detail, applied specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof; , for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention meanwhile.
