Preferably, distribution rules comprises following parameter:
| Number of regulation | The application server type | Application server address |
Wherein, the sequence number of number of regulation indication distribution rules is as 1,2,3 etc.; The type of application server type indication sip application server, for example server of instant message, Conference server, phone value-added service server etc.; The address of application server address indication sip application server, for example 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 dispensing device receives sip message and resolves, and particularly, message resolution module receives sip message from sip server, and sip message is resolved the analysis result information that obtains; Further, message resolution module sends message by analysis result analysis result information is sent to the distribution rules Executive Module.
Preferably, the analysis result transmission packet contains following parameter:
| Type of message | Message transmission module | The message sink module | The message sequence number | The application server type |
Wherein, type of message indication analysis result sends the type of message, for example is to send message or response etc.; Message transmission module and message sink module be the source and destination of Indication message respectively, for example message resolution module or rule execution module etc.; The message sequence number is indicated the position of resolved sip message in receiving sequence, is numeral or pointer etc.; The type of application server type indication sip application server, for example server of instant message, Conference server, phone value-added service server etc.
Step S3:SIP message dispensing device is according to distribution rules, the sip message analysis result is compared, particularly, the distribution rules Executive Module is according to the distribution rules that sets among the step S1, the analysis result information that receives from message resolution module is compared, for example compare, draw this sip message and should be distributed to which sip application server according to the application server type.
Step S4: the distribution rules Executive Module judges whether sip message satisfies distribution rules, if then forward step S5 to; Otherwise, forward step S6 to.
Step S5:SIP message dispensing device is distributed to corresponding sip application server with sip message, be exactly particularly, the message distribution module receives sip message distribution indication from the distribution rules Executive Module, get access to the sequence number and the purpose sip application server address of distribution sip message, the sip message of obtaining distribution according to the sip message sequence number from message sequence sends to the corresponding target sip application server.
Step S6:SIP message dispensing device abandons sip message, and abandons the result to the sip server feedback, is exactly that to not satisfying the sip message of any distribution rules, distribution rules Executive Module Indication message distribution module carries out default treatment particularly.According to the rule of default treatment, the message distribution module abandons this sip message, and abandons the result to the sip server feedback, and the method for feedback can be to send SIP form message, for example Notify message.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
