Abstract:
In one disclosed embodiment, a mobile unit receives an assigned reverse supplemental channel data rate, for example, as part of a supplemental channel assignment from a base station to the mobile unit in a cdma spread spectrum communication system. The mobile unit utilizes a profiling table to determine a maximum feasible reverse supplemental channel data rate corresponding to a given forward supplemental channel data rate. For example, the profiling table can be constructed by testing the mobile unit to determine what combinations of forward and reverse supplemental channel data rates and operating conditions cause the mobile unit's processor to "crash". The mobile unit communicates data over the reverse supplemental channel at a data rate which does not exceed the maximum feasible reverse supplemental channel data rate, for example, by constructing service data units using filler to lower the communication data rate below the maximum feasible reverse supplemental channel data rate.
Abstract:
A mobile station (16) may include a terminal equipment (10), a mobile statio n 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.
Abstract:
A system and a corresponding method for controlling transmission of a non-zero supplemental channel request message, denoted SCRM, by a wireless communication device are described, wherein the system comprising means for selectively enabling transmission of a non-zero reverse supplemental channel SCRM, denoted R-SCH SCRM, wherein transmission of a non-zero R-SCH SCRM is selectively enabled based in part on a predetermined characteristic of a reverse supplemental channel, R-SCH, burst.

Abstract:
En una modalidad expuesta, una unidad movil recibe una velocidad para transferencia de datos en un canal suplementario inverso asignado, por ejemplo, como parte de una asignacion de canal suplementario desde una estacion base hacia la unidad movil en un sistema de comunicacion de espectro extendido CDMA. La unidad movil utiliza una tabla de configuracion para determinar una velocidad para transferencia de datos de canal suplementario inverso factible maxima correspondiente a una velocidad para transferencia de datos de canal suplementario directo determinada. Por ejemplo, la tabla de configuracion se puede formar al probar la unidad movil para determinar cuales velocidades para transferencia de datos de canal suplementario directo e inverso y condiciones de operacion provocan que el procesador de la unidad movil "estalle". La unidad movil comunica los datos sobre el canal suplementario inverso a una velocidad para transferencia de datos que no exceda la velocidad para transferencia de datos de canal suplementario inverso factible maxima, por ejemplo, al formar las unidades de datos de servicio utilizando un relleno para disminuir la velocidad para transferencia de datos de comunicacion por debajo de la velocidad para transferencia de datos de canal suplementario inverso factible maxima.
Abstract:
The disclosed embodiments are a novel and improved method and system that prevents RLP3 from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The disclosed embodiments are efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. The disclosed embodiments are implemented with minimal changes to existing RLP3 implementation. The disclosed embodiments utilize a buffering scheme for all incoming traffic. The purpose of this buffering scheme is to reorder the received packets into the order that they were transmitted prior to delivering them to the PPP layer. Received frames are reordered by determinig the order that physical layer frames were transmitted by a peer, and by buffering each received frame until all frames transmitted prior to it have been received. The frame reordering is accomplished using timers and a memory buffering mechanism.
