Abstract: A method and system for disabling a mobile unit to handle a call processing function, after being away from its charging unit longer than a predetermined time period, allows a service provider to limit the mobility of the mobile unit with respect to its companion charging unit. Consequently, the service provider may limit the mobility of the mobile unit in a limited area, such as in a wireless local loop.

Abstract: A base station in a wireless communications network counts mobile stations receiving broadcast content via multi-user channel. The base station broadcasts a repeating message identifying at least one broadcast content stream and, for each stream, a REGISTER (R) or DO NOT REGISTER (DNR) indicator. Mobile stations periodically re-examine contents of this message. When the indicator is R for a broadcast content stream, mobile stations whose users have elected to receive it send the base station a registration message for that stream. When the number of registered mobile stations reaches a prescribed number, the base station changes the indicator to DNR. When the indicator is DNR for a broadcast content stream, mobile stations refrain from sending any registration message for that broadcast content stream. The base station may institute a recount by resetting the indicator to R.

Abstract: Methods and apparatus are presented herein for allowing a keyless access terminal (AT) to access a packet serving data node (PSDN) over a service network stream without deactivating the authentication functions of the authentication network stream.

Abstract: A method and apparatus for a communication system provide for fast link setup for a mobile station by transmitting a request message, transmitting an assignment message from the base station to the mobile station, and transmitting a notification message from the base station to a base station controller. The mobile station transmits an indication message to the base station controller indicating a successful completion of acquiring the data packet channel. The base station controller processes the indication message for message integrity and security feature. A portion of the available communication resources at the base station is allocated for an immediate response to the request message for acquiring a data packet channel.

Abstract: In wireless communications, transmission devices require continuous supplies of random data for encryption processes. The invention provides a method for generating a continuous pool of truly random data with hardware that is already available in conventional CDMA phones.

Abstract: A novel and improved method and apparatus, in a WCDMA communication system, for informing a mobile station of a downlink data frame time offset by determining the downlink data frame time offset, and transmitting the downlink data frame time offset via an Active Set Update message transmitted from a cell to mobile station. Once an Active Set Update message is received, the data frame time offset information is provided to a timing block which may determine data frame boundary of each downlink signal. Timing block may then adjust the PN sequence timing corresponding to the downlink signal associated with the data frame time offset such that corresponding data symbols in each data frame are correctly soft combined in a combiner.

Abstract: A method and apparatus for achieving crypto-syncronization in a packet data communication system employing cryptographic communications. In a transmitter, a state vector is incremented at a predetermined rate and is provided to an encryption module. The encryption module uses the state vector to sequentially encrypt the data frames. During periods of frame dropping prior to encryption, the state vector is disabled, thereby allowing for sequential encryption of the data frames. In a receiver, during a frame dropping condition, the state vector is advanced in proportion to the number of frames dropped. During an underflow condition at the receiver, the state vector is disabled for the duration of the underflow condition, and enabled once the underflow condition has passed.
