As shown in Figure 3, be the flow chart of service calling method in the embodiment of the invention IMS network, this method comprises:
301, service trigger unit receives first communication information;
Wherein, first communication information that service trigger unit receives in 301 can be sip message, is specifically as follows initial session request INVITE, and perhaps various sip response messages are such as 200,486 etc.
303, described service trigger unit is according to the described first communication information content, mate with the calling service rule that sets in advance, after the match is successful, generate and the irrelevant service calling request message of the affiliated session of described first communication information, and described service calling request message is sent to the Service Control Unit of describing in the calling service rule that the match is successful carries out calling service, wherein, described calling service rule comprises the calling service conditions needed combination of mating with the described first communication information content and carries out corresponding professional Service Control Unit descriptor.
Wherein, the calling service rule that sets in advance can be stored in the service trigger unit, perhaps is stored in independently in the storage entity, and service trigger unit is obtained from this storage entity in needs.The calling service rule specifically can be provided with jointly by operator, user or both, also can upgrade dynamically.The calling service rule generally can be made up of service trigger criteria and corresponding service control unit descriptor, wherein, service trigger criteria has been described the calling service conditions needed combination of mating with the described first communication information content, the combination of this condition has defined calling service institute must satisfied condition, with the divert when busy business is example, and the condition combination of its calling service can be met busy response message for receiving 486.Have only when the condition of describing in the first communication information content match service trigger criteria of receiving makes up, just call the corresponding service control unit and carry out calling service, when condition was sky, service trigger unit can unconditionally be called business.
In 303, service trigger unit can generate the calling service request according to the first communication information content of receiving and corresponding service control unit descriptor, and described service calling request message is sent to the Service Control Unit of describing in the calling service rule that the match is successful carries out calling service.
The address information that can comprise Service Control Unit in the described Service Control Unit descriptor, service trigger unit can be sent to Service Control Unit with service calling request message according to the address information of described Service Control Unit;
Can also comprise service identification information in the described Service Control Unit descriptor, can also comprise described service identification information in the service calling request message that then described service trigger unit generates, after described Service Control Unit receives described service calling request message, call corresponding service according to described service identification information, service identification information is mainly used in the situation that has a plurality of business on the single Service Control Unit of difference.
In addition, described calling service rule can also comprise the calling service request type information, then described service trigger unit can also be according to described calling service request type information, generate the corresponding business call request message, particular type can comprise sip message type and HTTP type of message, when being the HTTP type of message, can be specially the SOAP request message.
When the calling service request of described service trigger unit generation was sip message, described calling service request had different session identifications with first communication information.
When the calling service request that generates when described service trigger unit was HTTP message, this HTTP request belonged to new HTTP affairs, also with first communication information under session irrelevant, described calling service request this moment can be the SOAP service calling request message.
When the calling service request of described service trigger unit generation was HTTP message, service trigger unit generated described calling service request and can be specially:
The described first communication information content that service trigger unit will receive encapsulates or is mapped in the SOAP service calling request message.
The described first communication information content that is used to mate, when described sip message was request message, the described first communication information content can comprise one of following or combination in any: request URI, requesting method, message header field, message body content; When described sip message was response message, the described first communication information content comprised one of following or combination in any: message header field, message body content, conditional code.
When the calling service request of described service trigger unit generation is sip message, in order to realize separating of calling service and session control, the embodiment of the invention can be expanded a kind of sip message that carries out calling service, as the INVOKE method, this method is only represented a kind of call request, it and former session have nothing to do, and have the session identification that is different from former session, and former session is the session under first communication request message.
Concrete, the process that service trigger unit generates the request of INVOKE calling service can comprise: service trigger unit replaces with INVOKE with the method name of the sip message (first communication request message) received, former sip message method name places other position of calling service request, in Request-URI, such as, the Request-Line example of the sip message of receiving is as follows:
INVITE?sip:bob@biloxi.com?SIP/2.0
The Request-Line example of the INVOKE calling service request that generates is as follows:
INVOKE?sip:bob@biloxi.com?SIP/2.0；method＝INVITE
Perhaps, the process that generates the request of INVOKE calling service can also be: do not change former sip message method name, and the INVOKE method name is placed other position of calling service request, in Request-URI, still with the Request-Line example of the above-mentioned sip message of receiving, the Request-Line example of the INVOKE calling service request of generation is as follows:
INVITE sip:bob@biloxi.com SIP/2.0; Method=INVOKE
In 303, service trigger unit generates the calling service request mode and can comprise: default mode, or according to the calling service request type information in the calling service rule that the match is successful, wherein, default mode is meant the calling service request that always generates HTTP type or SIP type, be meant that according to the calling service request type information of the calling service rule that the match is successful which kind of calling service request of generation depends on the calling service request type information in the calling service rule that the match is successful, generate the calling service request of SOAP or INVOKE etc. as the type information description.
305, Service Control Unit is received the calling service request, carries out calling service, returns the calling service response.
In this step, if what Service Control Unit was received is the calling service request of HTTP type, as the request of SOAP calling service, the calling service response of then returning also is the calling service response of HTTP type, as the response of SOAP calling service, comprise packed or mapped sip message content in the response; Perhaps, if what Service Control Unit was received is the calling service request of SIP type, as the request of INVOKE calling service, the calling service response of then returning also is the calling service response of SIP type, as the response of INVOKE calling service, concrete, the response of INVOKE calling service can be a SIP method, as INVOKE_RSP, also can be a sip response sign indicating number.
The technical scheme of the embodiment of the invention, after receiving first communication information by service trigger unit, mate according to described first communication information content and the calling service rule that sets in advance, after the match is successful, generate and the irrelevant service calling request message of the affiliated session of described first communication information, be sent to the Service Control Unit of describing in the calling service rule that the match is successful and carry out calling service, owing to comprise the combination of calling service conditions needed in the calling service rule, when satisfying this condition combination, service calling request message just can be sent to the corresponding business control unit, thereby after having guaranteed that Service Control Unit is received this service calling request message, just carry out calling service immediately, thereby avoided signalling route is arrived unnecessary Service Control Unit, reduced route redundancy, shortened the time of call proceeding.In addition, because session is irrelevant under the service calling request message that service trigger unit generates and first communication information, so receiving the Service Control Unit of service calling request message can not join in the SIP session signaling route yet, realized thoroughly separating of calling service and session control, by service calling request message is sent to the WEB server by the HTTP carrying, thereby the WEB resource is incorporated in the IMS network, has further realized the fusion of IMS network and WEB network.
Provide the specific embodiment of using said method below.
As shown in Figure 4, be the schematic flow sheet of service calling method specific embodiment of the present invention, in the present embodiment, S-CSCF is a service trigger unit, and divert when busy AS is a Service Control Unit.The called divert when busy business of having contracted, the incoming call calling is by preceding commentaries on classics during Called Busy, and this method idiographic flow is as follows:
Step 1-4) calling UE _ A calls out UE_B, ring after process media negotiation and resource reservation are finished;
Step 5) called UE _ B is busy, response 486 busy Indication messages;
Step 6-8) S-CSCF is according to 486 message of receiving, coupling calling service rule generates a calling service request that is independent of former session, and sends to the Service Control Unit that is matched in the merit ground calling service rule, as the divert when busy AS in this example, 486 responses are transmitted to calling UE _ A;
Above-mentioned calling service rule comprises service trigger criteria and Service Control Unit descriptor, and its segment example is as follows:
<ServiceFilterCriteria>
<TriggerPoint>
<SPT>
<Response>486</Response>
</SPT>
</TriggerPoint>
<ApplicationServer>
<ServerName>http://ims.example.com</ServerName>
</ApplicationServer>
</ServiceFilterCriteria>
Wherein, TriggerPoint has described the service trigger criteria of this embodiment to be that service trigger unit triggers when receiving 486 response messages professional; ApplicationServer has described the Service Control Unit descriptor, the Service Control Unit descriptor has comprised the address information of Service Control Unit in this example, further, ApplicationServer can also comprise invoked service identification information, meet busy service as 000 representative, its example is as follows:
<ApplicationServer>
<ServerName>http://ims.example.com</ServerName>
<ServiceId>000</ServiceId>
</ApplicationServer>，
Wherein to have described the invoked service identification of this time be 000 to ServiceId;
Further, the calling service rule can also comprise the calling service request type information, comprises calling service request type daughter element in the calling service rale element, and the segment example is as follows:
<ServiceFilterCriteria>
<TriggerPoint>...</TriggerPoint>
<ApplicationServer>...</ApplicationServer>
<Method>HTTP</Method>
</ServiceFilterCriteria>
Method is the calling service request type information in the above-mentioned example, having described the calling service request type is the HTTP type of message, the calling service request of Service Control Unit generation is the calling service request of HTTP message bearing so, ask as SOAP, if the Method value is SIP, then Service Control Unit generates the calling service request based on SIP, as a kind of sip message that carries out calling service of expanding in the embodiment of the invention: the INVOKE method.When not comprising the calling service request type information in the calling service rule, Service Control Unit can generate the calling service request according to default mode.
Step 9) divert when busy AS receives the calling service request, and returns response;
Wherein, if AS accepts this request, then return success response, as the 200OK in the present embodiment; If refusal provides service, then return failure response.
Step 10-11) divert when busy AS carries out correspondent service logic according to the calling service request, generates the Refer request;
Wherein, carry the transferred number of called registration in the Refer request Refer-To header field.
Step 12-13) the Refer request is accepted in caller, and sends the INVITE request according to the URI in the Refer-To header field.
In the above-mentioned steps, S-CSCF is receiving INVITE request, during the 200OK (HTTP) of 180 responses and calling service request, also carried out the coupling of calling service rule, but coupling is unsuccessful, does not have the business that need call, so do not generate any calling service request.
Present embodiment is the example explanation with the divert when busy business only, and step 11 is execution results of divert when busy AS service logic, may not be the Refer request for other business, and this is determined by the logic of AS own with concrete professional relevant.
Obviously, present embodiment does not seal in divert when busy AS in the initial INVITE request, but when satisfying professional executive condition, just send the calling service request to divert when busy AS, this calling service process and session control are irrelevant, thereby after having guaranteed that Service Control Unit is received this service calling request message, just carry out calling service immediately, thereby avoided signalling route to unnecessary Service Control Unit, reduce route redundancy, shortened the time of call proceeding.In addition, because the service calling request message that service trigger unit generates is independent of former session, can not join in the former SIP session signaling route so receive the Service Control Unit of service calling request message yet, realize thoroughly separating of calling service and session control.
As shown in Figure 5, be the schematic flow sheet of another specific embodiment of service calling method of the present invention, in the present embodiment, S-CSCF is a service trigger unit, and call-missing prompt AS is a Service Control Unit.The called call-missing prompt business of having contracted, when called because of shutdown, busy or when not having the network coverage etc. and causing answering calling, call-missing prompt AS will send to the called subscriber by the call information that the mode of short message is missed the user, the phone of reminding the user to miss.This method idiographic flow is as follows:
Step 1-4) calling UE _ A calls out UE_B, ring after media negotiation and resource reservation are finished;
Step 5) called UE _ B is busy, response 486 busy Indication messages;
Step 6-8) S-CSCF is according to 486 message of receiving, coupling calling service rule, generate a calling service request that is independent of former session, and send to the Service Control Unit that is matched in the merit ground calling service rule, as the call-missing prompt AS in the present embodiment, and 486 responses are transmitted to calling UE _ A;
Above-mentioned calling service request can be HTTP SOAP request, also can be the new SIP method request of expansion, has comprised the required information of professional execution in this calling service request, as calling identification and call time etc.
Step 9) call-missing prompt AS receives the calling service request, and returns response;
Wherein, if AS accepts this request, then return success response, as the 200OK in the present embodiment; If refusal provides service, then return failure response.
Step 10-12) call-missing prompt AS is according to the calling service request, carry out correspondent service logic, generate the Message information and sending and give called UE _ B, the calling information that prompting UE_B misses, as: " 136XXXXXXXX sends a telegram here once to you at 10/01/2008 16:15 ".
In the present embodiment, called signatory call-missing prompt AS does not seal in the signaling paths when INVITE asks, but when the trigger condition that satisfies the call-missing prompt business (as busy), just call professional AS's, thereby after having guaranteed that Service Control Unit is received this service calling request message, just carry out calling service immediately, thereby avoided signalling route to unnecessary Service Control Unit, reduce route redundancy, shortened the time of call proceeding.And calling of call-missing prompt business do not influence original session, former session is proceeded, call-missing prompt AS is after executing respective logic, called call-missing prompt information is told in the request sent out again, the Service Control Unit that receives service calling request message can not join in the SIP session signaling route yet, realized thoroughly separating of calling service and session control.
As shown in Figure 6, be the schematic flow sheet of another specific embodiment of service calling method of the present invention, in the present embodiment, S-CSCF is a service trigger unit, and AoC AS is a Service Control Unit.The calling subscriber UE_A AoC business of having contracted, when UE_A called, AoC AS can notify the user rate that current communication is used, cost informations such as remaining sum.This method idiographic flow is as follows:
Step 1) calling UE _ A sends the INVITE request;
Step 2-4) S-CSCF is according to the INVITE request of receiving, coupling calling service rule generates a calling service request that is independent of former session, and sends to the Service Control Unit that is matched in the merit ground calling service rule, as the AoC AS in this example, and transmit INVITE and ask to the callee;
Step 5) AoC AS receives calling service request and response;
Step 6-8) AoC AS carries out correspondent service logic according to the calling service request, generates the INFO that carries cost information and returns to UE_A;
Step 9-10) calling UE _ A responds after receiving INFO;
Step 11-12) call setup, the INVITE request of called UE _ B response calling UE _ A.
In the present embodiment, the AoC business is called when S-CSCF receives the INVITE request and carries out, calling service process and former session are irrelevant, wherein step 7,8,9,10 can appear at former session and sets up in the process or behind the former conversation end, promptly step 7,8,9,10 and step 11,12 between restriction before and after not free.
In the present embodiment, S-CSCF is according to the INVITE request coupling calling service rule of receiving, generate a calling service request that is independent of former session, realized calling of AoC business, and AoCAS is not sealed in the signaling paths of former session, thereby reduced route redundancy, shortened the time of call proceeding.And calling of AoC business do not influence original session, and former session is proceeded, AoC AS generates the INFO carry cost information and returns to UE_A after executing respective logic, thereby realized thoroughly separating of calling service and session control.
Through the above description of the embodiments, the those skilled in the art can be well understood to the present invention and can realize by the mode that software adds essential general hardware platform, can certainly pass through hardware, but the former is better execution mode under a lot of situation.Based on such understanding, the part that technical scheme of the present invention contributes to prior art in essence in other words can embody with the form of software product, this computer software product is stored in the storage medium that can read, floppy disk as computer, hard disk or CD etc., comprise some instructions with so that computer equipment (can be personal computer, server, the perhaps network equipment etc.) carry out the described method of each embodiment of the present invention.
