Can see, the user proxy capability parameter is a kind of important parameter that carries out Business Processing, as previously mentioned, the sip user agent ability parameter can obtain from the sip message that user terminal sends, but in actual applications, user terminal may not have the ability of carrying the sip user agent ability parameter in the sip message that sends, perhaps user terminal may not have the transmitting capacity of sip message, at this moment, need a network entity in sip message, to add the sip user agent ability parameter, carry out corresponding service processing for follow-up application server, concrete steps are as follows:
Step 1: first network element is received the sip message that user terminal sends, and judges and does not carry the sip user agent ability parameter in this sip message, then generates the sip user agent ability parameter and adds in this sip message and send;
Step 2: the sip message that second network element sends to first network element, carry out corresponding service processing according to the sip user agent ability parameter that carries in this sip message, as processing such as business triggering, service logic controls.
First network element adds the sip user agent ability parameter in sip message mode has following four kinds:
Mode one: user terminal does not have the ability of carrying the sip user agent ability parameter in the sip message that sends, first network element of receiving described sip message is analyzed described sip message content or according to preset informations such as user signing contract informations, obtain the sender or the recipient's of described sip message attribute, and generate corresponding sip user agent ability parameter.Such as, first network element is received a sip message, analyzing called number, as carrying called number among the Request-URI is " 800 ", and the attribute that obtains the recipient after the first network element analysis is " freephone ", then generates corresponding sip user agent ability parameter, adding both caller preferences (Caller Preferences) in the sip message that sends is " freephone ", can see the sip user agent ability parameter of expression recipient's attribute, the service attribute of sender's use just; Carrying called number for another example among the Request-URI is " 166 ", the attribute that obtains the recipient after the first network element analysis is " a Voice Mailbox access code ", then generate corresponding sip user agent ability parameter, adding both caller preferences (Caller Preferences) in the sip message that sends is " automatic answering equipment "; For another example, after first network element is received sip message, this sip message is toggled to the server of handling PoC service according to user signing contract information, promptly this user signing contract information has shown that sender's attribute is " PoC ", first network element generates corresponding sip user agent ability parameter in view of the above, and adding ability of user terminal in the sip message that sends is " PoC "; For another example, first network element is handled game service, receive sip message and carry out the corresponding game Business Processing, promptly this business processing program itself has shown that recipient's attribute is " recreation ", first network element generates corresponding sip user agent ability parameter in view of the above, and adding both caller preferences in the sip message that sends is " recreation ".
Mode two: user terminal does not have the ability of carrying the sip user agent ability parameter in the sip message that sends, first network element of receiving described sip message generates corresponding sip user agent ability parameter according to the terminal capability that is kept at this user terminal in the network.Such as, at certain network element, as preserving ability of user terminal on the server, first network element is by sending a request message to this server, obtain the terminal capability of user terminal, described request message can be a query messages, sip subscribe message etc., if what carry in the request message is the sign of user terminal, as the contact address, device identification, privately owned sign etc., then this server carries the terminal capability of this user terminal correspondence in the response message that returns, if and what carry in the request message is user's sign, as public subscriber identification, then carry the terminal capability of these all terminals of user and the sign of corresponding user terminal in the response message that this server returns, after this, when first network element is received the sip message that this user's a terminal sends,, obtain the terminal capability of this corresponding terminal according to the sign of this terminal corresponding user terminal.
Mode three: user terminal does not have the ability of carrying the sip user agent ability parameter in the specific sip message that sends, receive that first network element of described sip message preserved the sip user agent ability parameter that carries before this from other specific sip message that user terminal sends, first network element obtains the sip user agent ability parameter of this preservation.Such as, user terminal has carried the sip user agent ability parameter in the SIP registration message that sends, when first network element is received this SIP registration message, preserve the sip user agent ability parameter that carries in the message, after this, user terminal does not carry the sip user agent ability parameter in the sip invite message that sends, after first network element is received this sip invite message, the sip user agent ability parameter of preserving joined in the sip invite message send.
Mode four: user terminal does not have the transmitting capacity of sip message, and first network element replaces the user to send sip message, carries the sip user agent ability parameter of described user terminal in the message.Such as, conventional terminal inserts IMS by one first network element, this first network element replaces conventional terminal to send sip message to the IMS network, as SIP registration message, sip invite message or sip response sign indicating number message etc., carry the sip user agent ability parameter of described conventional terminal in the message, as " conventional terminal ", " ISDN terminal ", " POTS terminal " etc.
In addition, obtained at first network element under the situation of terminal capability of user terminal, user terminal can be initiated subscribe request to first network element, and as sending sip subscribe message, first network element is in the subscribing notification message of returning, carry corresponding terminal capability, user terminal is received this subscribing notification message, obtains terminal capability, like this, when user terminal sends sip message, just can in the sip message that sends, carry corresponding sip user agent ability parameter.This wherein, when the user has an above terminal, when carrying the sign of a plurality of terminal capabilities of user and corresponding user terminal in the subscribing notification message that this user's a terminal is received, this terminal obtains corresponding terminal capability according to the sign of the user terminal of oneself.
Can see, first network element adds sip message sender or recipient's sip user agent ability parameter in sip message, or user terminal adds in the sip message that sends by subscribe to the terminal capability that obtains to first network element, being not limited only to aforesaid is the processing of automatic answering equipment to professional participant, but be applicable to the scene of various needs, such as, first network element adds the sip user agent ability parameter of conventional terminal in sip message, carry out corresponding service processing for second network element, as the Business Processing of distinguishing conventional terminal and IMS terminal etc.; For another example, first network element adds the sip user agent ability parameter in sip message, carries out the corresponding call route for second network element and handles, and different terminal capabilities is to different direction routes etc.
