摘要： A receiver includes a decoder configured to decode at least a portion of a data stream comprising a data frame. The data frame includes a code block having a data block and a parity block. The receiver also includes a controller. The controller is configured to determine whether to disable at least a portion of the receiver during transmission of the parity block to the receiver when the data block contains at least one erasure.

摘要： A wireless device establishes a data session with a data call, and a data connection is set up for the data session. The wireless device may receive or originate a voice call while the data session is dormant, exchange traffic data for the voice call, and perform handoff between base station controllers (BSCs), if needed, during the voice call. Upon termination of the voice call, the wireless device determines whether it has moved to a new packet zone during the voice call. This may be the case if the wireless device was handed off between BSCs located in different packet zones. If the wireless device has moved to a new packet zone, then the data connection is updated, e.g., by sending to the current serving BSC an origination message indicating no data to send. The network entities perform appropriate actions to update the data connection for the wireless device.

摘要： Systems and methods for improving the performance of wireless telecommunications networks by reducing data communications between a mobile station and a base station. One embodiment of the invention is implemented in an IS2000 (cdma2000) network. This network communicates data from a base station to a mobile station over a supplemental forward channel. In order to maintain the best communication channel for data transmissions, the mobile station monitors the signals received from an active set of base stations and identifies the strongest signal of a reduced active set so that the corresponding base station can be selected for data communications. Upon the occurrence of conditions indicating that a new base station within the reduced active set should be selected, the mobile station provides a notification to the base stations in the reduced active set so that further data transmissions will be made by the newly selected base station.

摘要： A mobile station (16) may include a terminal equipment (10), a mobile station modem (14), a mobile telephone (12), and other features. A CPU (52) selectively generates control signals to efficiently control transmission of supplemental channel request messages (SCRM) by the mobile station (16). In one embodiment, transmission of a SCRM in response to a predetermined event is prohibited until a fixed period of time has elapsed since the last transmission of an SCRM in response to the predetermined event.
