Embodiment
Below in conjunction with drawings and Examples the present invention is done detailed explanation.
See also Fig. 2, be the flow chart of the localization method of first embodiment of the invention urgent call, this method comprises:
Step 201: the AP sign that access point AP of living in (AP, Access Point) reports when receiving the UE urgent call;
Step 202: according to described AP sign, search the registrar database, obtain AP location information registered in advance;
In this step, be responsible at registrar (Register) under the situation of registration management of AP, the database of searching can be the database of this registrar, and finishes follow-up flow process by registrar.Certainly, this registrar also can be integrated among the OMC.For simplicity, below mainly be responsible for AP with registrar registration management be that example is described, but be not limited thereto.
Step 203:, this urgent call is positioned with the positional information of AP locating information as urgent call.
The technical scheme that the embodiment of the invention provides when AP receives urgent call, sends this AP and identifies to registrar, registrar is according to this AP sign, search the registrar database, obtain this AP location information registered in advance, as the locating information of urgent call.According to this locating information, this urgent call is positioned.Concrete mode can be: the positional information that shows this AP.Like this, the Operation and Maintenance personnel just can see that this AP urgent call occurred in covering, thereby can operate accordingly.
Below divide two kinds of scenes to describe respectively:
Scene one: UE does not carry the situation of SIM card
When AP receives urgent call, can only report AP to identify to registrar, this registrar is according to this AP sign, search the positional information of this AP, and position according to this positional information, such as the positional information that directly shows this AP, indicate in this AP coverage urgent call to have occurred.
Scene two: UE carries the situation of SIM card
When AP receives urgent call, can only report the AP sign equally.This registrar obtains the positional information of AP according to the AP sign.Certainly, also can obtain the UE sign of this urgent call earlier, again this UE sign and AP sign all be reported registrar.Wherein, this UE sign comprises: international mobile subscriber identity IMSI, cell-phone number or International Mobile Station Equipment Identity IMEI.In scene two, also divide several situations, will in the embodiment of back, be described in detail.
Understanding for the ease of those skilled in the art illustrates below in conjunction with specific embodiment.
See also Fig. 3, be the flow chart of the localization method of urgent call in the second embodiment of the invention, in the present embodiment, carrying SIM card with UE is that example describes.This method specifically comprises:
Step 301:AP stores the positional information of its registration in advance in registrar;
Wherein, when AP provided, AP need register in registrar.Comprise positional information in the information of registration, this positional information comprises: better address information and geographical position etc.Such as house number, longitude and latitude etc.This registration process is similar to existing ADSL housed device, does not repeat them here.
In addition, in the present embodiment technical scheme, because the positioning function of urgent call depends on the positional information of AP registration, so when AP opens an account granting, need the user that detailed address information is provided, and when this AP resettlement, need notify operator, so that its registered location information in registrar of time update.
What deserves to be explained is that the positional information of registration when AP provides for the method flow of present embodiment, is not to realize that at every turn this flow process all will finish this action, but registered in advance.
In addition, also can in the OMC of operation maintenance center, register (registrar is integrated in OMC), and finish follow-up flow process by OMC.For simplicity, the embodiment of the invention is that example describes with registrar Register.
Step 302:AP obtains the international mobile subscriber identity of this emergency call user when receiving urgent call;
When AP receives Radio Resource control request message, judge in this Radio Resource control request message and whether comprise emergency call information, if then obtain the international mobile subscriber identity IMSI of this emergency call user, and search the cell-phone number of correspondence according to this IMSI.Present embodiment is that urgent call is described with this calling, will not further describe being judged as situation not.
Step 303: judge according to this international mobile subscriber identity whether find corresponding cell-phone number, if then execution in step 304; Otherwise execution in step 305;
Step 304: this cell-phone number that finds and AP sign are sent to registrar, execution in step 307;
Because AP has found cell-phone number in step 303, then in this step, except reporting the AP sign, AP can also report this cell-phone number to give registrar.Be understandable that, report AP sign and report order that the step of cell-phone number carries out can be earlier can after, also can be simultaneously, the embodiment of the invention just for example, does not limit this.
Step 305: this international mobile subscriber identity and AP sign are sent to registrar, then execution in step 306;
Because in step 303, can not find cell-phone number, then in this step, except reporting the AP sign, AP can also report IMSI to give registrar.Equally, the order that reports IMSI and AP sign is not limited.
Step 306: this registrar gets access to corresponding cell-phone number according to international mobile subscriber identity from its data storehouse or attaching position register HLR; Follow execution in step 307;
Step 307: this registrar is searched the registrar database according to AP sign, obtains the positional information of AP, and with the positional information of AP, cell-phone number as locating information, this emergency call user is positioned.
Registrar is with the positional information of AP, the cell-phone number locating information as urgent call.Be understandable that this locating information can also comprise the urgent call time.The mode of concrete location can be: registrar shows that above-mentioned locating information, registrar send to urgent center EC by external transmission interface with locating information, or registrar provides external interface, is this locating information of search index with the cell-phone number for urgent center EC.
Further, show in the locate mode of locating information, the mode of two kinds of demonstrations is arranged at registrar according to whether special database being arranged at urgent call:
If mode one has special database to urgent call, navigate to when this registrar (i.e. the positional information of the AP at this user place) after the positional information of emergency call user, can initiatively show this positional information, UE sign and urgent call time.Be understandable that the UE sign that shows because registrar has reported by AP or the mode of self inquiry has been obtained cell-phone number, so can only show cell-phone number, certainly, also can show cell-phone number and IMSI number simultaneously herein.
If the database of storage urgent call in mode two registrar, it is the database of shared AP registrar, after then navigating to the positional information of emergency call user, can mark the sign of AP earlier, show the emergency call location information related then: AP positional information, urgent call time and UE sign with it.Specifically the mode of mark can be regarded mark as a parameter (Emergency flag), and this parameter is put 1, represents that the corresponding AP of this AP sign has urgent call in covering, and puts 0 expression normally.It should be noted that what is called marks the sign of AP, just represent the incidence relation of emergency call information and this AP, and this AP sign need not show in registrar.
More than be that example is described to search cell-phone number by IMSI, be understandable that, also can adopt the scheme of searching IMEI by IMSI.So, user's access tabulation (registrar and AP have) changes the corresponding relation of IMEI and IMSI into, and IMSI is still obtained from UE by AP.
If AP finds IMEI by IMSI, then can report IMEI to registrar.The locating information of urgent call comprises the positional information of AP, and this IMEI.
If AP searches less than IMEI by IMSI, then can report IMSI by AP equally, by registrar inquiry IMEI.Locating information comprises: the positional information of AP and IMEI, and same, can also comprise the urgent call time.
Employing is searched by IMSI in the scheme of IMEI, and the concrete mode of location is: registrar shows locating information, and external interface perhaps is provided, for the EC inquiry.Under the situation of EC inquiry, generally also needing with cell-phone number is index, and then registrar need be preserved the corresponding relation of IMEI and cell-phone number.Under specific situation, may EC can be that index is inquired about directly also, but because scene is too special, the embodiment of the invention will not be paid close attention to this by IMEI.
This shows that by the described scheme of the embodiment of the invention, promptly AP reports AP sign, obtains the positional information of AP registration, for the user of the emergency call in the AP coverage provides accurate localization.
Further, if SIM card is arranged, can also report the UE sign, no matter and be that AP directly reports cell-phone number, or registrar finds cell-phone number by IMSI, can be with the positional information of AP and cell-phone number as locating information, and locating information can also comprise the urgent call time.Like this, just make locating information more comprehensive.
Further, after having determined locating information, the embodiment of the invention provides multiple location specific implementation, such as showing, send locating information to EC or provide interface for the EC inquiry.Because EC can discern cell-phone number, for the EC inquiry or initiatively locating information is being sent in the locate mode of EC, with cell-phone number as index.Like this, make that the location of urgent call is versatile and flexible, adapt to the needs of different scenes and operator.
The technical scheme that the embodiment of the invention provides, can also and prior art in the flow process compatibility of urgent call.Such as, when core net receives urgent call, directly this urgent call is transferred to nearest urgent center, and informed the cell-phone number and the Service Area Identifier of this urgent call of urgent center; Urgent center knows it is that AP covers urgent call down by Service Area Identifier, the positional information of this urgent call that the registrar of inquiry correspondence then obtains according to the cell-phone number and the Service Area Identifier that receive.Described with the form of a specific embodiment below.
Consult Fig. 4, be the signaling process figure of the localization method of urgent call in the third embodiment of the invention.This embodiment is that the situation of carrying SIM card with urgent call UE is an example, and registrar is after the more specific location information that navigates to the emergency call user, and the situation of this emergency call user more specific location information is inquired about at urgent center.In this implementation procedure, navigate to the detailed process of emergency call user's more specific location information for registrar, see the foregoing description for details, present embodiment is only simple to be described, and its implementation procedure comprises:
Step 401:AP is to its positional information of registrar registered in advance;
Step 402:UE makes a call to AP, and AP judges whether this calling is urgent call;
This step makes a call in the process, and UE sends wireless resource control connection request (RRC ConnectionRequest), and this AP judges by the byte in the wireless resource control connection request whether this calling is urgent call.If definite reason (Establishmentcause) of byte is urgent call in this wireless resource control connection request, judge that then this calling is urgent call, carry out step 403.Otherwise, being normal call, the flow process of this normal call is a known technology to those skilled in the art, does not repeat them here.
Step 403:AP obtains the international mobile subscriber identity IMSI of this emergency call user;
In this step, UE carries SIM card, its corresponding IMSI.For the access user of AP, can utilize UE to call out the MSISDN that the access flow process obtains the emergency call user correspondence.The implementation procedure that this UE calls out the access flow process is: on AP pre-configured access tabulation (being the matching table of IMSI and MSISDN), when obtaining the IMSI of urgent call, by searching the matching table in this access tabulation, obtain the cell-phone number MSISDN of this emergency call user correspondence, its concrete implementation procedure is a known technology to those skilled in the art, in this no longer detailed description.
In this step, if the user is not the access user of AP, so, AP can not obtain the MSISDN of this user's correspondence.
In this step, even the user is the access user of AP, under special circumstances, it is also imperfect to tabulate such as the access of AP preservation, the situation of corresponding MSISDN also may occur not finding.
According to the result of step 403, if get access to the situation of user MSISDN, then execution in step 404; If do not obtain the situation of user MSISDN, then execution in step 405.
Step 404, AP are reported to Register with this AP sign and MSISDN, and Register positions urgent call in view of the above;
Step 304 and step 307 in the operation similar embodiment two of this step repeat no more herein.Till this step, if what registrar adopted is the locate mode that demonstration or reporting orientation information are given EC, can think and finish location urgent call, provide the locate mode of external interface if adopt for the EC inquiry, can also execution in step 406, with the urgent call flow process compatibility of prior art.
Step 405, AP are reported to Register with this AP sign and IMSI, and Register positions (as shown in phantom in FIG.) to the user of emergency call in view of the above.
Step 305,306 and 307 repeats no more herein in the operation similar embodiment two of this step.Similarly, till this step, if what registrar adopted is the locate mode that demonstration or reporting orientation information are given EC, can think and finish location urgent call, provide the locate mode of external interface if adopt for the EC inquiry, can also execution in step 406, with the urgent call flow process compatibility of prior art.
That is to say that after execution in step 404 or 405, Register has multiple to the concrete locate mode that gets access to after the locating information.Such as, show locating information automatically by registrar; Or this directly is transferred to locating information urgent center by the coffret on the registrar; Perhaps, then provide inquiry etc. by the external inquiry interface if registrar provides the external inquiry interface.
It is example that present embodiment provides the external inquiry interface with AP, comprising:
Step 406:UE sets up urgent call by access gateway AG and core net, and core net is judged the cell-phone number and the service area information thereof of this urgent call;
Step 407: core net sends to nearest urgent center with this cell-phone number and Service Area Identifier thereof;
Step 408: urgent center is an index with the cell-phone number that receives, and inquires about to registrar;
In this step, urgent center at first receives cell-phone number and Service Area Identifier, knows it is that AP covers urgent call down by Service Area Identifier, is index then with the cell-phone number, the registrar of inquiry correspondence, the positional information of this urgent call of obtaining.
Wherein, step 407 to 408 in, identical with grand network urgent call treatment concerning core net, according to the Service Area Identifier that receives nearest urgent center is transferred in urgent call, inform the cell-phone number and the Service Area Identifier of urgent call simultaneously.Because the SA that disposes among this AP is planned that by operator the configuration mode that can adopt can be:
The service area SA of mode one, direct multiplexing grand network, urgent center does not need to increase configuration, can choose the positional information whether the registrar inquiry has this cell-phone number of correspondence.If this configuration mode can not navigate to the urgent call in the AP scope,, also need by conversing definite if accurately locate.
Mode two, be that AP increases special-purpose SA, and will dispose AP special use to all AP or certain limit, locate according to the range of definition of SA at so urgent center, promptly if the positional information that registrar is inquired about corresponding this cell-phone number is then directly arrived in the AP special use.Because this configuration mode can navigate to the interior urgent call of AP scope, determines particular location and do not need to pass through in addition conversation, so embodiment of the invention employing should middle configuration mode.But being not limited to disclosed this dual mode, also can be other mode.
In said process, step 406 to the effect of step 408 is in order to illustrate that the embodiment of the invention can be after registrar navigates to concrete emergency call user's more specific location information, make things convenient for the inquiry at urgent center, and it is made corresponding emergency processing.It is the compatible existing position fixing process of present embodiment to urgent call.
