摘要:
A first sequence state storage module (20) periodically stores a present state (22) of a long code generator (30). Following a restoration of power after a power cut condition, or following the termination of any other interruption of the generation of the long code, a sequence recovery module (50) then provides an updated present state (36). The updated present state (36) is based upon a stored present state (24) and a time value (52) that is reset whenever the present state (22) of the long code or other sequence is stored and that is available even when the long code or other sequence is interrupted.
摘要:
A method of making a geographic location determination via a cellular telephone in signal communication with a base station. The mobile station first attempts to detect a position location signal. Upon determining that the position location signal is insufficient to use in a position location calculation, the mobile station deactivates at least a portion of a receiver. The mobile station receives a cellular communication signal and measures a signal quality of the cellular communication signal. Responsive to the signal quality improving by a predetermined amount, the mobile station reactivates the receiver portion and re-attempts to detect the position location signal.

A modular communication device (102), which provides for radio frequency (RF) communication in a communication system (100), comprises a first modular unit (106) and a second modular unit (108). The first modular unit (106) includes a housing (110); a user interface (113) including a display (114) and keys (116); electrical circuitry (605), including a transceiver (606) coupled to an antenna (610); a battery connection interface (308) for receiving a battery (302); and a connection interface (120). The second modular unit (108) includes a housing (128); a user interface (135) including a speaker (650), a microphone (648), and a keypad (140); a retractable antenna (134); a battery connection interface (402) for receiving a battery (142); and a connection interface (143). When the connection interfaces (143, 120) are connected, the user interface (135), the antenna (134), and the battery connection interface (402) are coupled to the electrical circuitry (602).

An apparatus (100) generates a preferred roaming list (108) for a wireless mobile station (404) that includes area identification data (such as GEO GROUP_ID) (200) corresponding to an area serviced by at least one wireless wide area network, such as a ground based CDMA system and an area services by at least one in-vehicle wireless pico-cell (402), such as a wireless CDMA pico-cell located on an aircraft or any other suitable vehicle. The area identification data (200) is associated with a wireless in-vehicle pico-cell system identification data (205) and in the case of a CDMA pico cell system, a system identification data SID) and network identification (NID) data pair (206) associated with the in-vehicle wireless pico-cell (402).
摘要:
A mobile station (201) having an improved receiver capability over legacy mobile stations may detect additional base stations (205, 209) for the candidate list (219). The mobile station (201) provides a receiver capability indication to the network via a message such as an origination message, a page response message, a handover message, or a registration message. The message may utilize one or more bit fields of an information packet (300), or otherwise an information element (401) to convey the receiver capability information. The BTS (203) or BSC (109) will accordingly customize the mobile station handover parameters to better utilize the mobile station capabilities.
摘要:
A method for key press registration in an electronic device uses a first key press debounce limit (233) if a first housing of the electronic device has not moved relative to a second housing of the electronic device and a second key press debounce limit (236) if the first housing has moved relative to the second housing. In one implementation, the second debounce limit is at least twice the first debounce limit. By using different debounce limits based on whether housing movement has recently been detected, the electronic device reduces the effect of an inadvertent key press made while opening or closing the electronic device.
摘要:
A method and system for evaluating the validity of location fixes of a mobile station by comparison of a location fix for which a validity determination is desired with one or more prior reference location fixes. In one embodiment, a satellite positioning system based location fix of a satellite positioning system enabled cellular mobile station in a cellular communications network is validated by comparison of the satellite positioning system based location fix to one or more of a plurality of network based location fixes, or to an estimated future location fix of the mobile station.
摘要:
A method (200) in a CDMA terminal device for acquiring a system identified in an enhanced preferred roaming list (enhanced PRL), with at least one entry containing a mobile country code, includes the steps of obtaining (210) system identifiers from SYNCH channels on a scan list, determining (220) if the system identifiers match entries on the enhanced PRL, and inserting (226) channel information items on a first list if the system identifiers do not match entries on the enhanced PRL. If all channels on the scan list have been scanned without any system identifiers matching entries on the enhanced PRL, the method obtains (246) mobile country codes using channel information items from the first list, determines (250) if the mobile country codes match entries on the enhanced PRL, and camps (283) on a system if its mobile country code matches an entry on the enhanced PRL.
