SYSTEM AND METHOD FOR THE SOLICITATION OF PRESENCE INFORMATION FROM PRESENCE SOURCE
摘要:
Disclosed is a system and method for directly requesting and receiving presence information from a presence source. The system for providing a presence service, which includes a presence source which stores presence information about at least one presentity, previously registers presence information elements, which the present source can publish, in a SIP/IP (Session Initiation Protocol/Internet Protocol) core in accordance with corresponding each media feature tag value, and publishes presence information according to media feature tag values when specific presence information is requested; a SIP/IP core which allows presence information elements registered by the presence source to each media feature tag value so as to store the presence information elements, allows the media feature tag value described in the message to correspond to a previously registered media feature tab value of the presence source so as to identify a presence source to which the message for requesting the presence information will be published when the SIP/IP core receives the presence information from the presence server, and transmits the message for requesting the presence information to corresponding presence source; and a presence server, which allows a media feature tag value regarding the corresponding presence information to be included in the message for requesting presence information so as to request specific presence information from the presence source, and then transmits the message for requesting presence information, which selectively includes a publication rule regarding corresponding presence information of the corresponding source.
