Wherein, the sequence number of number of regulation instruction distribution rules, as 1,2,3 etc.; The type of application server type instruction sip application server, such as server of instant message, Conference server, telephone VAS services server etc.; The address of application server address instruction sip application server, such as IP address or URL (Uniform Resource Locator, URL(uniform resource locator), is also referred to as web page address) address etc.
Step S2:SIP message distribution device receives sip message and also resolves, and particularly, message resolution module receives sip message from sip server, and carries out parsing to sip message and obtain analysis result information; Further, message resolution module sends message by analysis result and analysis result information is sent to distribution rules Executive Module.
Preferably, analysis result transmission packet is containing following parameter:
| Type of message | Message transmission module | Message reception module | Message sequence number | Application server type |
Wherein, type of message instruction analysis result sends the type of message, such as, be send message or response etc.; The source and destination of message transmission module and message reception module difference Indication message, such as message resolution module or rule execution module etc.; The resolved position of sip message in receiving sequence of message sequence number instruction is numeral or pointer etc.; The type of application server type instruction sip application server, such as server of instant message, Conference server, telephone VAS services server etc.
Step S3:SIP message distribution device is according to distribution rules, sip message analysis result is compared, particularly, distribution rules Executive Module is according to the distribution rules set in step S1, the analysis result information received from message resolution module is compared, such as carry out comparison according to application server type, show which sip application server this sip message should be distributed to.
Step S4: distribution rules Executive Module judges whether sip message meets distribution rules, if so, then forwards step S5 to; Otherwise, forward step S6 to.
Sip message is distributed to corresponding sip application server by step S5:SIP message distribution device, be exactly particularly, message distribution module receives sip message distribution instruction from distribution rules Executive Module, get sequence number and the object sip application server address of distribution sip message, the sip message obtaining distribution according to sip message sequence number from message sequence is sent to corresponding object sip application server.
Step S6:SIP message distribution device abandons sip message, and abandons result to sip server feedback, is exactly that, to the sip message not meeting any distribution rules, distribution rules Executive Module Indication message distribution module carries out default treatment particularly.According to the rule of default treatment, message distribution module abandons this sip message, and abandons result to sip server feedback, and the method for feedback can be send SIP form message, such as Notify message.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
