Abstract: A method and apparatus for determining the data rate of a reverse link communication. An embodiment includes transmitting at a null rate on the communication channel only when the station is not transmitting voice, signaling, or data. An embodiment includes determining a maximum requested rate based on the normalized average pilot transmit power and the pilot reference value, and determining the timing of the rate request. An embodime nt involves determining a maximum transmission rate. An embodiment involves determining sufficient power and a power-control set point.

Abstract: Method and apparatus for congestion control in a wireless communication system. Individual target data rate values are assigned individual access terminals. The individual data rates of the access terminals are adjusted to achieve the corresponding individual target data rate values. If the target values are not achieved within a predetermined number of iterations, the individual data rate is adjusted. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease, wherein the status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. According to one embodiment, a congestion indicator includes multiple bits, wherein at least one bit instructs the mobile station to use target values or else to adjust without regard to a target value.

Abstract: A mobile wireless telecommunications system, which includes base stations (30) of a first type operating according to a first air interface, and base stations (36) of a second type operating according to a second air interface. Methods and apparatus are provided for handing over a mobile station (40) in the system from a first base station (30), which is of the first type, to a second base station (36), which is of the second type. A communications link is established over the first air interface between the mobile station (40) and the first base station (30). Data is received from the mobile station (40) responsive to a signal received by the mobile station (40) over the second air interface from the second base station (36), substantially without breaking the communications link with the first base station. The mobile station (40) is handed over from the first (30) to the second base station (36) responsive to the data received therefrom.

Abstract: Techniques to reduce the amount of registration required by a mobile station in a wireless communication system, especially if the registration zones are defined to be small areas. In one scheme, a mobile station registers (e.g., at R-level) with a network entity (e.g., a base station) each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. The mobile station maintains a timer for each zone with which it has already registered but has since left. If the mobile station leaves a particular zone for a period longer than a time-out period, the registration with that zone times out, and the mobile station re-registers with that zone whenever it re-enters the zone. The mobile station may implement zone-based, timer-based, implicit, traffic channel RR, and some other registrations, or a combination thereof. Parameters to facilitate registration may be defined by a base station.

Abstract: Method and apparatus for congestion control in a wireless communication system. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease, to be performed at an access terminal to determine the next data rate for transmissions on the reverse link. The status of the congestion bit is determined by comparing a congesti on parameter to a predetermined threshold (186). One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. The outerloopthreshold is adjusted in response to comparin g a measured congestion metric to the desired threshold (192, 194, 196). The outerloop threshold adjustment maintains the congestion metric to within a predetermined probalility of exceeding the desired threshold.
