    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: In accordance with an exemplary embodiment of the invention, an apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload a standard power level and transmitting a smaller payload at a boosted power level. The mobile station, therefore, can autonomously select a QoS (Quality of Service) level for physical layer packets. Based on reverse link transmission information received from a base station, the mobile station derives a reverse link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse link transmission power level from a plurality of power levels including at least a standard reverse link transmission power level associated with a standard payload size and a boosted reverse link transmission power level associated with a boosted payload size where the standard payload size is greater than the boosted payload size.

    Abstract: Invenţia se referă la un sistem şi la o metodă pentru transferul unei staţii mobile într-un sistem de radio telecomunicaţii mobile (GSM), careeste folosit în reţele de telefonie celulară, în multe ţări din întreaga lume. Metoda pentrutransferul unei staţii mobile într-un sistem detelecomunicaţii radio mobil constă în: stabilirea unei prime legături de comunicaţie prin prima interfaţă radio, care este staţia mobilă, şi cea de-a doua staţie de bază; stabilirea unei a doua legături de comunicaţie prin cea de-a doua interfaţă radio, care este staţia mobilă, şi cea de-a doua staţie de bază; recepţionarea datelor la prima staţie de bază, datele cuprinzând o măsurătoare a intensităţii semnalului de la staţia mobilă, în principal, fără a întrerupe legătura de comunicaţii cu prima staţie debază; transferarea staţiei mobile de la prima la cea de-a doua staţie de bază, ca răspuns la datele recepţionate de la aceasta; transferarea informaţiei de temporizare. Sistemul de radiotelecomunicaţii utilizat conform invenţiei cuprinde: ostaţie de bază de un prim tip, care transmite şi recepţionează un prim semnal, conform cu o primă interfaţă radio; o staţie de bază de un al doilea tip, care transmite şi recepţionează un al doilea semnal, conform cu o a doua interfaţă radio; o staţie mobilă, ce recepţionează al doilea semnal prin a doua interfaţă radio, de lastaţia de bază de al doilea tip.

    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.
