摘要:
A method and apparatus is provided for simultaneously accessing a broadcast channel which allows for maintaining registration on the broadcast channel and a second channel. The broadcast channel includes a reverse link access channel for a portable communication device (120) to send registration messages to a base station and the method initially includes the step of determining whether a predetermined event requiring registration of the portable communication device on the broadcast channel has been detected (302, 304, 306). After detecting the predetermined event, it is determined whether the portable communication device is communicating on the second channel (308). If not communicating on the second channel (308), registration on the broadcast channel is accomplished by transmitting a registration message on the reverse link access channel (320). If communicating on the second channel (308), the registration message is transmitted on the broadcast channel asynchronously (340) or, if supported by the base station (110), as a databurst of a packet of information on the second channel (330).

A method includes the provision of a list, which identifies a condition of at least one memory module. Attempted access to the at least one memory module is identified. The list is utilized to determine whether or not the at least one memory module is in a first condition. An exception is generated when the at least one memory module is in the first condition. A system includes: a list processing module, configured to identify a condition of the at least one memory module; an access identifying module, configured to identify access to the at least one memory module; a list controlling module, configured to determine whether or not the at least one memory module is in a first condition; and an exception generating module, configured to generate an exception when the at least one memory module is in the first condition.

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).

An apparatus and method for route navigation for multiple destinations. Route parameters can be received and a route (140, 142) can be generated for multiple destinations (132, 134). An estimated time of arrival can be calculated for each destination. An updated estimated time of arrival can be generated for one of the destinations. A messaging service message including the updated time of arrival can be sent to a recipient (122, 124) associated with the respective destination if the updated time of arrival deviates from the original estimated time of arrival.
摘要:
In a method of configuring a mobile communication between a position determination entity and a mobile device, an indication that the mobile device has an ability to perform a positioning system search simultaneously with a communication is sent to the position determination entity. A preferred response quality indicator is set to a state that will allow the mobile device an extended period to provide to a location of the mobile device to the position determination entity when the mobile device has the ability to perform a positioning system search simultaneously with a communication.

摘要:
Systems and methods for determining the envelope of a modulated signal using high bandwidth and low bandwidth samples of a hybrid signal. The hybrid signal is obtained by mixing the modulated signal with its carrier signal. The systems and methods of the present disclosure may be suitable for equivalent-time or real-time oscilloscopes.

摘要:
A system, method, and apparatus is disclosed for enabling a constant modulus algorithm (CMA) to be reliably used for blind equalization training of an equalizer. According to one embodiment, received signals in a binary phase shift keying (BPSK) format are converted to a quadrature phase shift keying (QPSK) format, to which CMA processing can be reliably applied for equalization. According to another aspect of this embodiment, the equalized QPSK signals are rotated to convert the signals to an equalized BPSK format for output.
