摘要： A direct sequence code-division multiple access (DS CDMA) communication system schedules conveyance of blocks (400) of information such that the blocks arrive at a base-site (130) just-in-time for transmission during a discrete frame (301-305) of an air-interface. The DS CDMA communication system implements both circuit switching and packet switching approaches to provide trunking efficiencies while balancing between system loading constraints and time delay of blocks (400) during conveyance.

摘要： A method of communication handover from a first communication entity (33) to a second communication entity (43) in a communication system (10) where a communication unit (80), communicating with a transceiver (23) associated with the second communication entity, is linked to the first communication entity. The invention provides for establishing a communication link between the communication unit and the second communication entity while maintaining a communication link between the communication unit and the first communication entity. Then, communications are substantially simultaneously transferred to the second communication entity while terminated from the first communication entity.

摘要： A base-site (304) combines baseband frequency hopping and fast-synthesizer hopping to produce an economical frequency hopping communication system (300). The base-site (304) combines the fast-synthesizer frequency hopping capability of transmitters (307-309) with baseband frequency hopping to produce a frequency hopping communication system (300) which serves the same number of subscribers served by transmitters (208-213) in a purely baseband hopping communication system (200), but with fewer transmitters (307-309). The implementation of frequency-selective cavities (312-317) having very low loss eliminates the need for wideband hybrid combiners (112-114), which in turn eliminates transmitted-signal power loss experienced in a purely fast-synthesizer frequency hopping communication system (100).

摘要： A method in a wireless communications network connected to a packet network including receiving (410) at a packet server handover information, e.g., neighbor measurements, from a wireless communications device, negotiating (420) with the radio communications network, e.g., with a base station controller, for a radio resource transfer for a mobile wireless communications device, and sending (440), from the packet server, radio resource information to the mobile wireless communications device.

摘要： A locking function or device (136) for a wireless communication unit (102) and corresponding method locks the communication device (102) to a network of a selected service provider such that the communication device (102) is limited to a lower functionality level if used with another service provider. The locking function (136) unlocks or permits the communication device (102) to be unlocked such that the communication device (102) is not limited to the lower functionality level when used with a network other than the selected network when an accrued measure of usage of the communication device (102) reaches a predetermined level. The accrued measure of usage corresponds for example to accrued revenue generated by the communication device (102).

摘要： A method and system for facilitating a handoff of a remote mobile unit in a communication system (12) having a plurality of base stations (16 and 22), employs base stations (16 and 22) along a coverage area seam (10) that have a soft handoff subsystem (24) collocated with conventional base station circuitry (44) to facilitate soft handoff. The soft handoff subsystem (24) includes a transceiver (36) for generating and receiving a first group of dedicated soft handoff channels that are an orthogonally related subset of a separate second group of spread spectrum coded traffic channels wherein the soft handoff subsystem is under control of the source base station controller (14). The dedicated soft handoff channels are assigned to a specified source base station (16). Preferably the soft handoff subsystem (24) generates only the first group of dedicated soft handoff channels without pilot channels or synchronization channels.

摘要： In a communication system (100) where a remote unit is given a time offset for a base station (102) and hands off to the base station (102) if the remote unit (113) can acquire the base station within a time window surrounding the time offset, a remote unit (113) utilizes the time offset of each base station (supplied by a serving base station (101) via downlink communication signal (116)) and searches for neighboring base stations within the time window surrounding its PN offset. The time window surrounding an individual base station's PN offset is allowed to vary depending upon whether the communication system (100) is time synchronized. In particular, a base station (101) supplies the remote unit (113) with an indication that the communication system (100) is operating in a synchronized or an unsynchronized mode, and the remote unit (113) varies the time window (search window) accordingly.

摘要： In a communication system where frame boundaries for the discrete frames for different users may be offset relative to one another, assignment of a remote unit (125) to a particular frame offset occurs by a processor (321) determining a frame offset belonging to a group that is the least busy group of all possible groups. In addition, during handoff of the remote unit (125) from a serving base station (130) to a neighboring base station, the remote unit (125) is attempted to be kept within the same call group, however should the same call group of the neighboring base station be filled, the remote unit (125) is placed in a second call group that is one call group prior to the current call group.

摘要： A wireless communication system (200, 300, 400, 500) mitigates the effects of excess timing delay caused by varying lengths of communication paths. In one general implementation, a transition communication path (206, 323, 329) is used to transfer a time-advanced version of a timing reference signal so that the cumulative time delay at a transition cell (209, 325, 331) is reduced. In another general implementation, the timing reference signal is time-advanced in all communication paths (403-411), and selected communication paths (403-407) include a time delay means (423-427, 503-507) such that the cumulative time delay at an area (421) near a target coverage area (130) is reduced. By reducing the cumulative time delay at the area (421) near the target coverage area (130), a hand-off of a communication of a mobile station (128) into the target coverage area (130) can be performed.
