摘要： A method for selecting a channel for group communications in a conventional multi-channel communication system comprises receiving, for a plurality of channels in the multi-channel communication system, a talkgroup assignment list for the channels that identifies a set of talkgroups assigned to use the corresponding channels. A subscriber unit receives talkgroup assignment lists for multiple different channels, determines a desired talkgroup, and selects a channel assigned to the desired talkgroup using the received talkgroup assignment. The talkgroup assignment list is developed for at least one channel in the multi-channel communication system and identifies a set of talkgroups assigned to use the corresponding channel. The list is transmitted for the channel to a subscriber unit and is used by the subscriber unit to register with the system and affiliate with a talkgroup supported by the channel in the conventional multi-channel communication system.

摘要： A method and system for synchronization of link layer windows in a wireless communications system is disclosed. At a transmitter in the wireless communications system, the transmitter transmits a plurality of frames in a transmitter's link layer window, wherein each frame comprises segments and sends a request for an acknowledgement of the plurality of frames to a receiver. Then the transmitter determines a last transmitted segment of an eldest frame of the plurality of frames in the transmitter's link layer window, if a response to the request is not received within a specified time period and sets a synchronization indicator in the determined last transmitted segment of the eldest frame. Finally, the transmitter transmits the determined last transmitted segment of the eldest frame with the synchronization indicator set to the receiver.

摘要： The application discloses a method and apparatus for providing interoperability for a mobile subscriber unit (MSU), employing a first protocol e.g., SCEP, with a packet-data subsystem operating at a second protocol e.g., SNDCP. The method includes determining that the first protocol employed by the MSU is different from the second protocol operated by the packet data subsystem. The method then includes creating a context information for the MSU when the determined first protocol is different from the second protocol. Further, the method includes determining a header associated with the second protocol based on the created context information and then receiving at least one data packet associated with the first protocol from the MSU. The method then encapsulates the at least one data packet with the determined header associated with the second protocol. The method then transmits the at least one encapsulated data packet to the communication network through a context manager.
