摘要： An Internet Protocol Multimedia Subsystem (IMS) network uses the Session Initiation Protocol (SIP) to provide communication services to mobile nodes. A short message service gateway (SMS-GW) in the IMS network receives a request to deliver a message to a mobile node. The SMS-GW determines whether the mobile node is IMS registered. If the mobile node is IMS registered, the SMS-GW may transmit a SIP MESSAGE request to a call session control function (CSCF) serving the mobile node in order to deliver the message to the mobile node. If the mobile node is SIP-capable but is not IMS registered, the SMS-GW may instead transmit a SIP MESSAGE request to the mobile node's IP address. To obtain the mobile node's IP address, the SMS-GW may query a domain name server (DNS) that stores associations between hostnames and IP addresses of mobile nodes.

摘要： An originating mobile station seeks to establish a push-to-talk (PTT) communication session with a destination mobile station. To do this, the originating mobile station transmits a first request message that requests the PTT session. Before receiving a predefined indication that the requested PTT session has been accepted, the originating mobile station transmits a first continuation message that includes first session description information to facilitate establishment of the PTT session. A PTT server receives the first request message and, before receiving the first continuation message, transmits to the destination mobile station a second request message that requests the PTT session. The PTT server then transmits a second continuation message that includes second session description information. The destination mobile station receives the second request message and, before receiving the second continuation message, transmits an acceptance message indicating acceptance of the requested PTT session.
