Abstract: A method and apparatus dynamically assigns each of a plurality of different information streams associated with one wireless communication unit (12a), to independent communication resources from different communication resource pools from each of a plurality of different wireless network elements (14a-14n), based on, for example, quality of service requirement data determined for each of the information streams. As such, the wireless communication unit (12a) may establish two or more separate links using two or more completely independent radio resources from different wireless base stations in the same system.

Abstract: An apparatus enabling multiple client devices to access a SIM card, coupled to a server device, along a local link, that includes a SIM card interface and a router unit. The SIM card interface couples the SIM card to the server device, formats the commands from the client devices for transmission to the SIM card, and formats responses to the commands for transmission from the SIM card to the client devices. The router unit routes the commands from the server device to the SIM card interface, and routes the responses to the commands for transmission along the local link from the SIM card to the client devices. A broadcast message is transmitted by the router unit along the local link to the client devices in response to detecting a physical presence signal transmitted by the SIM card interface in response to the SIM card being coupled to the SIM card interface.

Abstract: A system for rapidly acquiring a time reference for the location determination of a wireless communication device. The system includes a wireless communication device (200), a GPS satellite (202) and a communication satellite (208). The method comprises the steps of acquiring a communication satellite signal (210) and using the finite frame time to establish a course time reference. Once the course time reference is established, an absolute device time is determined by the wireless communication device, which as a result is synchronized to the absolute time of the communication satellite (208) to within ten milliseconds. The absolute device time is then used to synchronize the GPS portion of the wireless communication device with the GPS satellite system.

Abstract: 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.

Abstract: In a radio frequency communication system (100), infrastructure transceivers operate in a configuration mode (301-306) and an active mode (307). When in the configuration mode, a given infrastructure transceiver (106-109) derives information regarding RF operating circumstances proximal to the infrastructure transceiver. The information regarding the RF operating circumstances, information regarding the infrastructure transceiver itself, and optionally information regarding present location of the infrastructure transceiver, is transmitted to a communication system configuration server (105). In response, information regarding operation of the infrastructure transceiver is received by the infrastructure transceiver. When in the given infrastructure transceiver is in the active mode, the information regarding operation of the infrastructure transceiver is used to support communications in the RF communication system. With each infrastructure transceiver operating in this manner, the radio frequency communication system can be automatically configured.

Abstract: A technique for decoding and removing a single subscriber's signal from a composite signal in a DS-CDMA system is provided. A particular subscriber's signal is removed from the composite signal by despreading the composite signal (120) to form a multiplicity of despread QPSK signals representative of multiple subscribers. Next, multipath characteristics are determined (303) for each of the multiple subscribers. Utilizing multipath characteristics (204), the multiple subscribers' signals are determined by combining multipath components of each signal (305). Next, data related to a particular subscriber is determined (307) and the subscriber's signal is "reconstructed" to contain multipath characteristics (204) as originally received (309). Finally, the reconstructed signal is output to a summing node (128) where it is combined with the delayed composite signal (120).

Abstract: A method of reducing interference within a cellular system (10) by partitioning a designated frequency spectrum within a service coverage area (.0.1, .0.2, or .0.3) into a first and at least second spectrum inclusive of the designated frequency spectrum, each with an associated power level, and offsetting the spectrums for each TDM frame under the control of an offset number unique to each TDM frame. Assignment of communication units to a spectrum and power level are based upon distance from the base site (as determined through signal strength measurements). The spectral content of spectrums in adjacent service coverage areas is adjusted to include non-coincidental frequencies.

Abstract: An equalization system for equalizing a corrupted signal is disclosed. The equalization system includes a complex matched filter (400) and a maximum likelihood sequence estimator (MLSE) (405) for removing the effects of phase shift, amplitude variations, intersymbol interference, etc. resulting from multi-pathing and noise contributed by the receiver front end. The system estimates a correlation signal C(t) (505) and synchronizes C(t) 505 to maximize its energy as seen on the taps of the complex matched filter (400). Taps having amplitude coefficients below a predetermined threshold are set to zero to produce a modified CIR estimate. The modified CIR estimate which has had the effects of noise virtually eliminated, is then used to construct the complex matched filter (400) and is also used as input to the MLSE (405) to produce a better equalized data signal.
