摘要： A method of collapsing a communication path among at least two communication units (104-107) reduces the number of sites normally required to provide a communication. Each of a plurality of site controllers (103) in a radio communications system has a corresponding coverage area (100, 101), and at least some of the coverage areas (710-712) overlap one another. The method includes the step of determining (402) whether the communication units are currently being serviced by different sites, and then determining (405) whether they can be serviced by a common site. When the communication units are serviceable by a common site, the call might be established (406) through the common site, resulting in a reduced number of sites required to complete a call.

摘要： 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.

摘要： To address the need to provide power control for listening participants of CDMA dispatch services, the concept of “shared channel signaling windows” for shared traffic channels (e.g., 110) is described. In one embodiment, the beginning of a signaling window is announced on the traffic channel and the remote units (e.g., MS 120) with the highest frame error rates compute the shortest transmit delays. For the duration of the window, remote units transmit their power control signaling according to their transmit delays. Thus, listening participants are given an opportunity, according to need, to perform power control signaling on the group traffic channel.

摘要： In general, the present invention discloses a method and an apparatus that provide a dispatch patch service in a CDMA communication system (100). A communication unit (103) involved in a dispatch call requests a base site (101) to patch a patch target (105), either a dispatch group or an individual, into the present call. By providing the CDMA long-code mask being used for the present call to the patch target and the dispatch identifier of the patch target to at least the communication unit, a new CDMA long-code mask can be generated and used for the dispatch call going forward.

摘要： A CDMA base site provides dispatch group call service to members of a dispatch group by using a first long-code mask. The base site also repeatedly transmits the group call's channel assignment so that a scanning communication unit can detect that the call is active. In order for the scanning communication unit to decode the dispatch communication once the call is detected, it requests a long-code mask transition from the base site. The base site then transmits a new long-code mask and begins encoding the dispatch communication using the new mask. Thus, the scanning communication unit is able decode the communication and thereby join the active CDMA dispatch group call.
