摘要： An apparatus (100) maintains a Pilot Set in a digital communication system that utilizes Code Division Multiple Access. The apparatus comprises a logic and control circuit (113) for providing instructions to a searcher receiver (109). The searcher receiver, in response to the instructions, sequentially scans active pilots, then candidate pilots, and then pre-candidate pilots. The scan of the pre-candidate pilots continues until all but a predetermined number of pre-candidate pilots have been promoted or demoted. Then the searcher receiver alternately scans the predetermined number of pre-candidate pilots and the neighbor pilots. The searcher receiver terminates alternate scans of the predetermined number of pre-candidate pilots and the neighbor pilots when a one of the neighbor pilots is promoted, and resumes the scan of the pre-candidate pilots.

摘要： A circuit (2) and method employing logic circuitry (30) and memory (40) identifies a reverse link limited channel (80). The logic circuitry (30) identifies a reverse link limited channel based on determining that an access probe failure occurred on a channel (64). The logic circuitry (30) causes the memory to store reverse link limited channel data (80) in response to the logic circuitry (30) determining that the access probe failure occurred. The reverse link limited channel data (80), for example, may be a channel identification associated with the channel (64), a base station identification associated with the channel (64), a location identification of the circuit (2) or any data suitable for identifying and adapting dynamically to the reverse link limited channel.

摘要： Methods in communications devices and networks for reducing an infrastructure registration race condition. In one embodiment, a communications device transmits (310) a first network connection request is a first network, and after waiting a specified time interval, the communication device transmits (320) another network connection request to the first network. The communications device may determine the time interval, or it may be received (302) from the network. Alternatively, a time stamp or some other indicium is applied to the connection requests transmitted by the communications device so that a home location register or other entity may determine the order in which the requests were transmitted.

摘要： A wireless communication device 100 acquires a pilot channel before an assigned slot when the wireless communication device is operating in the slotted mode of a CDMA system. The wireless communication device comprises a searcher receiver 107 that determines the short-term average pilot strength of active and neighbor pilot channels. Finger receivers 107 determine the long-term average pilot strength of the active and neighbor pilot channels. A logic and control circuit 113 assigns the finger receivers to the pilot channels according to their short-term average pilot strength, determines if the long-term average pilot strength of a neighbor channel is greater than the active pilot channel's pilot strength, and determines to hand off to the neighbor pilot channel with the greater long-term average pilot strength. Moreover, an early detection correlation length can be dynamically adjusted according to the pilot strength of the active pilot channel to shorten the pilot acquisition process.

摘要： A searcher receiver (114) includes a sample buffer (202) which stores signal samples loaded using a real time clock. A real time linear sequence generator (RT LSG) (206) stores an initial state and is clocked using the real time clock. The contents of the RT LSG are loaded into a non-real time linear sequence generator (NRT LSG) (208) when sample processing begins Samples are correlated using a non-real time clock to allow signal processing to be uncoupled from the chip rate. The analog front end (108) may be powered down or tuned to another frequency during non-real time processing.

摘要： A Multiple Protocol Signal Detector, MPSD (320, 500) has a mixer (406) that receives signal energy from a multi-band antenna system (324) via a low noise amplifier (402) and from a variable frequency synthesizer (408) via a first variable band pass filter (410). The output of the mixer (406) passes through a second variable band pass filter (416) to an envelope detector (418) a power detector (419) and a low resolution A/D (420) that inputs digitized samples to a binary modulation detector, BMD (422). A controller (424) configures the aforementioned devices of the MPSD (320) to detect communications using different protocols based on a scan Look Up Table (426).
