Abstract
Multimedia IMS communications are established by matching callee capabilities with caller preferences and identifying a URI parameter in response thereto. When a session initiation protocol (SIP) request identifying caller preferences for an internet communication session and an identified callee is received (602), a determination is made of whether the identified callee is a registered address of record (AOR) or not (604). If the identified callee is a registered AOR (604), a uniform resource identifier (URI) parameter and a globally routable user agent URI (GRUU) associated with callee capabilities are identified (608, 612, 614). The URI parameter is used to create a modified SIP including the URI parameter (616) for sending (618) to an IMS enabled wireless communication device (120).
