Can comprise recipient's tabulation in the SIP INVITE request message of being distributed, certainly the indication in the content corresponding processing mode can only be used as a kind of historical information as " recipient-list-history " and " handling=optional " expression to this tabulation, and the distribution situation of this INVITE is described.Can not comprise also in the SIP INVITE request message of being distributed that the recipient tabulates, as long as comprise SDP (Session Description Protocol) content.Be the address of actual conference centre (Focus) in Contact field in the SIPINVITE request message distributed of Conference server in addition, and what send request by features tab " isgocus " indication is a conference centre.
Step 407 and 408 receives that the 3rd user agent UA3 of SIP INVITE of distribution and four-function family act on behalf of UA4 etc. and return the 200OK response to Conference server, can set up corresponding conference session subsequently.
Can also utilize the method for present embodiment, the indication user sends SIP MESSAGE to a plurality of targets.Wherein specifying requesting method among the Refer-To in the REFER Reference News is MESSAGE, and the content of Refer-To is exemplified below:
Refer-To：<sip:list-service.example.com；method＝MESSAGE>
Also similarly in message body comprise recipient tabulation, the user agent who receives this REFER Reference News is carried at this tabulation in the message body of the MESSAGE that is sent to Distributor address " sip:list-service.example.com ", certainly the message body of this MESSAGE generally also comprises the body matter of message, can be mime type arbitrarily such as text, image.Distributor then is distributed to this MESSAGE message each address in recipient's tabulation.
Among above-mentioned three embodiment, if in the REFER of initialization Reference News, comprise in Referred-By field and the message body corresponding signature contents is arranged, then in other sip request messages of REFER Reference News that distributes or distribution, should duplicate Referred-By field and corresponding signature contents.The user agent who finally receives sip request message can carry out authentication to Referred-By field and the corresponding signature contents that it comprised.Can be about Referred-By field referring to standard RFC3892.Because general raw content and the signature contents that all comprises Refer-To field in Referred-By the corresponding signature contents of field, then to above-mentioned second embodiment, because the actual corresponding recipient's tabulation in the message body of Refer-To field, therefore need comprise list content and encrypt after signature contents, amount of information is bigger, if and how in recipient's tabulation some address be close sending " bcc " or anonymity, then can't provide original recipient's tabulation to final recipient, promptly can't verify, therefore can simply only comprise Referred-By field and get final product signature contents.Perhaps do not comprise the content of Refer-To field in the signature, as long as allow final recipient can authenticate the initial time on date that to send out Reference News be that who sends and send etc.
The 4th embodiment has described the recipient that how to indicate REFER Reference News and has made a call by the SDP parameter of appointment.
Step 501, the first user agent UA1 sends REFER Reference News, comprises the SDP content of parameter in its message body.Message content is exemplified below:
REFER?sip:bill@example.com?SIP/2.0
Refer-To：<sip:conf-123@shenzhen.example.com>
Content-Type：application/sdp
Content-Disposition：referred-with
m＝message?0TCP/MSRP*
Content Type C ontent-Type is the SDP content of " application/sdp " in the message body of above-mentioned message, and its contents processing mode is " referred-with ", and indication will be carried this content in the request that REFER Reference News is triggered.Certainly for above-mentioned SDP content as " m=message 0TCP/MSRP* ", when sending the request triggered such as INVITE, can increase or revise this SDP content, promptly this SDP content is not to force to carry this SDP content as just reference and indication information.Usually the SDP content of carrying in REFER Reference News is fairly simple, can only specify conversation type such as MSRP or the RTP etc. that wish foundation, and needn't comprise concrete communication port numbers etc., because these user agents oneself that need receive REFER Reference News decide.As can replenish the other guide of SDP in the INVITE request that sends, as version number, port numbers or the like, amended SDP complete content is exemplified below:
v＝0
o＝alice?28908445572890844559IN?IP4alicepc.example.com
s＝-
c＝IN?IP4alicepc.example.com
t＝00
m＝message?7777TCP/MSRP*
a＝accept-types：text/plain
a＝path:msrp://alicepc.example.com:7777/iau39soe2843z；tcp
In the INVITE request that the destination address of appointment in Refer-To field sends, carry above-mentioned complete SDP content.The method of present embodiment also can be applied among above several other embodiment.
The 5th embodiment has described the MESSAGE message that sends given content by REFER Reference News indication Distributor to a plurality of destination addresses.
At first first user agent sends REFER Reference News, specifying the session initiation protocol method that triggers is MESSAGE, the message text that comprises recipient's address list and MESSAGE in the message body, and in the contents processing mode of text, comprise carry the indication as " refer-with ".The partial content of REFER Reference News is exemplified below:
