    Abstract: The present invention addresses the need for an apparatus and method for providing dispatch group and individual call services on a CDMA communication system. Generally, the present invention discloses modifications to the IS-95 CDMA standard such as substituting a dispatch identifier (e.g., 201) for the Electronic Serial Number (ESN) used to generate CDMA long-code masks (e.g., 211). In the present invention, transmitted voice information is encoded using a long-code mask thus derived. In addition, a dispatch identifier is used to determine (306 and 404) the appropriate paging resource for transmitting and receiving dispatch call pages.

    Abstract: To address the need to provide listening participants of CDMA dispatch services soft handoff signaling capability, the concept of "shared channel signaling windows" for shared traffic channels (e.g., 110) is described. In one embodiment, the base site (105) announces the beginning of a signaling window for the traffic channel, allowing remote units (e.g., MS 120) that need to send handoff signaling an opportunity. In response to such signaling, the base site directs soft handoff information to the signaling remote units via the traffic channel. However, all the remote units that share the traffic channel can store this soft handoff information and later use the information to initiate soft handoffs without needing to exchange handoff messaging with the base site. Thus, a CDMA-dispatch, shared-channel implementation is enabled by providing soft handoff signaling windows and the over-the-air, soft-handoff messaging required for dispatch services is reduced.

    Abstract: During a communication session (101) for a multi-network user platform (which communication session is presently occurring in a first network and is terminable by a Session Initiation Protocol server as comprises a part of that first network), one establishes (102) in the first network a Session Initiation Protocol instance as corresponds to the communication session. Thereafter, and particularly following a handoff of the communication session from the first network to a second network, one uses (104) the Session Initiation Protocol instance to maintain communications with the Session Initiation Protocol server such that the Session Initiation Protocol server does not terminate the communication session.

    Abstract: During (101) a communication session for a plurality of user platforms wherein at least one of the user platforms is on hold and wherein the communication session is presently occurring in a first network and is terminable by a Session Initiation Protocol server as comprises a part of that first network, one establishes (102) in the first network a Session Initiation Protocol instance as corresponds to the communication session wherein the Session Initiation Protocol instance comprises, at least in part, session context information for the user platform that is on hold. Then, following a handoff of bearer support of the communication session from the first network to a second network, one uses (104) the Session Initiation Protocol instance to maintain the hold status of the user platform that is on hold with the Session Initiation Protocol server subsequent to the handoff such that the Session Initiation Protocol server does not terminate the communication session.
