Embodiment 1

[0091] In this embodiment, it is assumed that a SIP INVITE message is received and the IMS application server AS1 is called. After that, when the called user does not answer, the call is forwarded to the voice mailbox, the voice mailbox responds, and a 200 OK response response message is returned. AS1 does not want to receive the 200 OK message automatically answered by the system, so the 200 OK message should be shielded from AS1.

[0092] In order to realize the 200 OK message automatically responded to the AS1 shielding system, in this embodiment, the existing iFC is expanded, and pre-processing description information corresponding to AS1 is set in the service filtering rules in advance. For the sake of simplification, only a fragment of the service filtering rule related to this embodiment in a complete service filtering rule is listed below:

Embodiment 2

[0136]In this embodiment, it is assumed that a SIP INVITE message is received and the IMS application server AS2 is called. After that, when the called user does not respond, AS2 wants to withdraw from the current communication. Therefore, it should send a new call message to AS2.

[0137] In order to enable AS2 to withdraw from the current communication when the called user does not answer, in this embodiment, the existing iFC is expanded, and pre-processing description information corresponding to AS2 is set in the service filtering rules in advance. For the sake of simplification, only a fragment of the service filtering rule related to this embodiment in a complete service filtering rule is listed below:

Embodiment 3

[0173] In this embodiment, it is assumed that a SIP INVITE1 message is received, and the IP TV (IPTV) AS is called to provide IPTV services to the user; then, when the user receives an incoming SIP INVITE2 message, the IPTV AS should pause The user plays the video stream so that the user can accept the new incoming call and establish a call with the caller of the new incoming call; after that, when the new incoming call is released, IPTVAS should resume playing to the user Video streaming. Therefore, there are two communication processes in this embodiment, one is the communication between the user and the IPTV, and the other is the communication between the user and the new incoming caller.

[0174] In order to realize the suspension of the IPTV AS service when the user receives a new incoming call, and the restoration of the IPTV AS service when the new incoming call is released, the method of extending the existing iFC is adopted in this embodiment. Set the preprocessing descri...

Abstract

The invention discloses a pretreatment method for a service control unit, which first implements service filtering rules, confirms the called service control unit and the corresponding pretreatment description information, and then deals with the current communication according to the pretreatment description information in the process of carrying out service. The invention also discloses a pretreatment device and a system for the service control unit. The signaling path of service control unit can be regulated by utilizing the invention in the process of communication subsequent process, thus which solves problem of service interaction and conflict and improves the efficiency of the call establishment and shortens call spicing time.

Description

Technical field [0001] The invention relates to the service invocation technology of the Internet multimedia subsystem, in particular to a preprocessing method, device and system for a service control unit. Background technique [0002] The Internet Protocol Multimedia Subsystem (IMS) is an IP multimedia subsystem defined by the 3rd Generation Partnership Project (3GPP). The IMS network uses the Session Initiation Protocol (SIP) as call control signaling, and is the target network for the 3G mobile communication network to provide unified multimedia services and applications. [0003] In the IMS network, the session layer and the service layer are separated, and IMS provides the necessary methods for invoking services. The host execution environment of various services is called the service control unit, which can provide various service logic control functions. The service control unit includes an IMS application server, a traditional intelligent network service control function...
