Definitions
- the present invention relates to a service invocation technology of an Internet multimedia subsystem, and in particular, to a method, apparatus and system for processing a service control unit. Background of the invention
- the Internet Protocol Multimedia Subsystem is an IP Multimedia Subsystem defined by the 3rd Generation Partnership Project (3GPP).
- the IMS network uses the Session Initiation Protocol (SIP) as the call control signaling, which is the target network for the 3G mobile communication network to provide unified multimedia services and applications.
- SIP Session Initiation Protocol
- the session layer is separated from the service layer, and IMS provides the necessary method for the call of the service.
- the host execution environment for various services is called the Service Control Unit and provides a variety of business logic control functions.
- the service control unit includes an IMS application server, a traditional intelligent network service control function entity (SCF, Service Control Function), and the like. Taking the IMS application server as an example, the process of providing services in an IMS network includes the following three basic steps:
- Step 1 Define a possible business or business collection
- Step 2 When the user orders/modifies the service subscription relationship, the user-specific service data is created in the form of an initial filter rule (iFC, Initial Filter Criteria);
- iFC Initial Filter Criteria
- the iFC includes a service call condition and its corresponding application server (AS, Application Server), and the service call condition is described by a service point trigger (SPT, Service Point Trigger), and the content of the SPT includes: a request-uniform resource identifier (Request-URI), identifying the resource pointed to by the SIP initial request; a SIP method (Method) indicating the type of the SIP initial request; a SIP header field (Header) containing information related to the SIP initial request, Can be any SIP header field and its header field content; Session Case, there are three possible values, ie start, terminate or terminate unregistered; Session Description, any session description within the SIP method SDP (Session Description Protocol) field content.
- SPT Service Point Trigger
- Step 3 When the service-call session control function (S-CSCF) receives the SIP initial request, according to the current session situation and the received SIP initial request message, the iFC is executed to determine the current session situation and the SIP initial request. Corresponding application server, and the received SIP initial request is delivered to the determined application server.
- S-CSCF service-call session control function
- the S-CSCF receives a SIP Invite message (INVITE), and according to the execution of the iFC, sequentially calls the three application servers AS1, AS2, and AS3, and sends the INVITE message to the called user; Bell, suppose the called user has opened the no-answer forwarding voice mailbox service. After the ringing timeout, the call is forwarded to the voice mailbox; the voice mailbox answers, and the S-CSCF receives the response message from the voice mailbox (200 OK) .
- the 200 OK message will be sent to AS3, AS2 and AS1 according to the established signaling path.
- AS2 receives the 200 OK message, it considers that this is the 200 OK message returned by the user, and the voice message will be played to it.
- the 200 OK message in this example is actually returned by the voice mailbox. Obviously, AS2 cannot receive the 200 OK message.
- the application server can only be triggered by the SIP initial request message, such as: can only be triggered by INVITE message, instant message (MESSAGE), subscription message (SUBSCRIBE) and reference message (REFER), ie iFC Only SIP initial request messages are processed; however, some application servers actually need to be triggered only in certain scenarios during communication. For example, handle busy call forwarding (CFB, Call Forwarding)
- CFB Call Forwarding
- the application server CFB AS of Busy needs to be triggered only when the called user is busy.
- the CFB AS must be Triggered, and if the called user is currently idle, the CFB AS will be useless in the signaling path. Obviously, this reduces the efficiency of call setup and prolongs the call connection time.
- a complete, normal call setup procedure will pass through the INVITE message, the 183 response code message, the temporary acknowledgement message (PRACK), the 200 response code message, the update message (UPDATE), the 200 response code message, and the 180-vibration.
- the bell response message, the PRACK message, the 200 response code message, the 200 response response code message, and the acknowledgement message (ACK) have a total of 11 messages.
- AS1 only needs to receive 4 messages of INVITE message, 180 ringing response message, 200 response response message, and ACK message to implement business logic control, and S-CSCF sends all messages to AS1. Reduce the efficiency of call setup and extend the call duration.

- a subsequent filtering rule corresponding to the called service control unit is set in the service filtering rule according to the processing situation that may be occurred in the service execution process of the called service control unit.
- the subsequent filtering rule is a concept introduced by the present invention with respect to the initial filtering rule (iFC), indicating that the filtering rule is a service filtering rule set according to a processing situation that may be occurred in the service execution process of the called service control unit.
- Subsequent filtering rules include subsequent trigger conditions and their corresponding subsequent processing methods.
- the subsequent triggering conditions include at least one of a subsequent message, a call state, a service control unit call failure, and a service control unit call success; the subsequent processing manner includes sending a message, rejecting the message, calling the specified service control unit, continuing the communication, and stopping.
- the subsequent message in the subsequent trigger condition refers to all messages after the service control unit is called (that is, after receiving the service trigger message) until the current communication is released, and also includes the release message.
- it may be a response code message of a SIP initial request message, or any SIP method or the like.
- the message name, message content and any combination of the subsequent messages can be used as subsequent trigger conditions; one or more subsequent messages may be included in the subsequent trigger conditions.
- subsequent messages can be divided into the following two categories:
- One is a message returned by the called service control unit, including a SIP initial request message, a SIP response code message (the message is a response code message of a SIP initial request message invoking the service control unit), and other subsequent SIP method messages (eg, SIP PRACK message, SIP A BYE message, etc., that is, a subsequent SIP method message that invokes the SIP initial request message of the service control unit).
- SIP initial request message e.g, SIP PRACK message, SIP A BYE message, etc., that is, a subsequent SIP method message that invokes the SIP initial request message of the service control unit.
- the other is a message sent to the called service control unit, including a SIP initial request message (unlike the SIP initial request message that invokes the current service filtering rule to invoke the service control unit), and a SIP response code message (the message is generally called)
- SIP initial request message unlike the SIP initial request message that invokes the current service filtering rule to invoke the service control unit
- SIP response code message the message is generally called
- the response code message of the SIP initial request message returned by the service control unit and other subsequent SIP method messages (ie, subsequent SIP method messages of the SIP initial request message returned by the called service control unit).
- the source information can indicate: the subsequent message is the same message as the SIP initial request message that invokes the service control unit, or the message that is the same as the SIP initial request message returned after the service control unit is called. , or a new SIP initial request message.
- the homology may be further represented as being located in the same call, session, or conversation.
- the call state in the subsequent trigger condition includes all process states of the current communication and any combination thereof.
- the call status includes: collecting information, analyzing information, routing failure, originating_busy, originating_non-answering, originating_responding, originating_disconnection, originating_abandonment, terminal attempting authentication, Terminal_Busy, Terminal_No Answer, Terminal_Answer, Terminal_Remove, Terminal_Abandon.

- 3GPP TS 24.229 3GPP TS 23.278 and 3GPP TS 24.229, which are not described here.
- the timeout waiting time of the call state may also be described in the subsequent filtering rule.
- the failure of the service control unit call in the subsequent trigger condition means that the called service control unit does not respond, or the service logic call in the called service control unit fails.
- the latter indicates that the service control unit is called normally, and the response is returned, but the user is not on schedule. Provide the corresponding business.
- the reason for the failure of the business logic call may be that the user has no permission or no data to use the service, a function failure in the service control unit, and the like.
- the business logic call failure is different from the case where the business logic in the service control unit is normally called but the communication fails. For example, if the call restriction service is called, it is a communication failure.
- the related protocol may be extended such that when the business logic call fails, the service control unit may return a message indicating that the business logic call failed, for example, return a SIP response code indicating that the business logic call failed or a SIP message carrying a service logic call failure indication. Wait.
- the failure of the various service control unit calls may be separately described, for example, the service control unit does not respond or the service logic fails to be invoked, and the failure of the various service control unit calls may be uniformly described.
- the returned failure message may be used as a subsequent message in the subsequent trigger condition to indicate that the service logic call fails, and the call state in the subsequent trigger condition may also be used to indicate that the service control unit does not respond.
- the successful call of the service control unit in the subsequent trigger condition means that the invoked service control unit is successfully invoked, and the service control unit returns a message indicating that the service logic call is successful, for example, returning a SIP response code indicating that the service logic call is successful or carrying the business logic. Call the SIP message indicating the success. If the message returned by the service control unit does not explicitly indicate whether the service logic is successfully invoked, such as receiving an initial SIP request message, and returning an initial SIP request message that does not carry the service logic call success indication, the default may also be considered. The service control unit was successfully called.
- the sending message in the subsequent processing mode is: Send the specified message.
- the subsequent processing mode only the name of the specified message may be described, and the content of the specified message may be described. Further, the source and/or destination of the sent message may be distinguished in the subsequent processing manner. Specifically, depending on the source information, sending messages can be divided into the following three types:
- the first type is the message returned by the called service control unit.
- the second type is a message sent to the called service control unit.
- a description of the source information refer to the corresponding description of the source information of the subsequent message in the subsequent trigger condition as described above.
- the third is to call the SIP initial request message of the service control unit, that is, the service trigger message.
- the sending message may be a subsequent message in the subsequent triggering condition.
- the destination information of the sent message may be: sending a message to the called service control unit, sending a message to the called service control unit (ie, starting direction of the current communication, such as sending a message to the calling party), to the called service
- the control unit sends a message backward (ie, the end direction of the current communication, such as sending a message to the called party).
- the reject message in the subsequent processing mode is: It is forbidden to send subsequent messages in subsequent trigger conditions.
- the destination of the reject message may also be distinguished in a subsequent processing manner to indicate that the subsequent message is prohibited from being sent to the destination.
- the destination information of the reject message may be: refusing to send a message to the called service control unit, rejecting the forward sending message to the called service control unit (such as the calling direction), or refusing to the called service control unit.
- the message is sent backwards (such as the direction of the called party).
- the call in the subsequent processing mode specifies that the service control unit is: Sends an invocation message to the specified service control unit.
- the address of the service control unit may be directly specified, or may be specified indirectly, for example, the identifier of the service filtering rule corresponding to the specified service control unit is described in the subsequent filtering rule (the address of the specified service control unit is described in the service filtering rule)
- the call to the specified service control unit will be implemented by the execution of the business filter rule.
- calling the specified service control unit is divided into the following three cases:
- the first case is to re-invoke the service control unit, and the subsequent processing mode can be used to process the subsequent trigger condition that the service control unit fails to be called, that is, the call message is resent to the service control unit that failed the call; Used to process subsequent triggers
- the condition is that the service control unit is successfully invoked, that is, the call message is sent again to the service control unit that successfully invokes. At this time, the call message sent again may not be the call message of the previous successful call of the service control unit.
- the homogeneous service control unit is called, that is, the call message is sent to the homogeneous service control unit.
- This subsequent processing mode can be used to process the subsequent trigger condition as the service control unit call fails.
- the homogeneous service control unit refers to a service control unit that can provide the same service as the service control unit that has failed the current call. If the AS7 call fails, and the AS8 can provide the same service as the AS7, the AS8 is called and a message is sent to the AS8.
- the address of the homogeneous service control unit can be set in the service filtering rule together with the address of the called service control unit, so that when the service filtering rule is executed, the address of the homogeneous service control unit corresponding to a certain service control unit can be obtained. .
- the third case is to call a new service control unit, which specifies the address of the new service control unit, and sends a call message to the designated new service control unit.
- the communication in the subsequent processing mode continues to: Continue processing the current communication. Specifically, if there is a subsequent service filtering rule, the subsequent service filtering rule is executed, otherwise the current communication process continues to be processed, for example, continuing to the called route, or sending the currently processed communication message to the calling party.
- the subsequent processing manner of invoking the new service control unit when the new service control unit corresponds to the subsequent service filtering rule, the method may also be implemented in this manner.
- the execution of the service filtering rule in the subsequent processing mode is: If there is a subsequent service filtering rule, the subsequent service filtering rule is stopped, and the current communication is continued, for example, continuing to the called route.
- the release service control unit in the subsequent processing mode is: releasing the service control unit that has been called.
- the sending message in the subsequent processing mode may also be set as a release message, such as a SIP BYE message, a SIP CANCEL message, etc., to indicate that the service control unit that has been called is released.
- the communication in the subsequent processing mode is released as: Release the current communication.
- the method provided by the preferred embodiment of the present invention enables the service filtering rule to process subsequent messages in the communication process in addition to the SIP initial request message, that is, to provide a communication according to the subsequent filtering rule.
- the subsequent filtering rules in the embodiment of the present invention may be set by extending the existing iFC, or may be separately set.
- the existing iFC is extended to describe the subsequent filtering rules in the iFC, so that the initial filtering rule iFC that can only process the SIP initial request message is expanded to have the capability of processing subsequent messages.
