    Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. In an embodiment, an access terminal is configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the AT belong to different cells. The access terminal is further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC provides an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced. A method for handoff is further disclosed using DSC as early indication of handoff, which also trigger multitasking forward traffic for the access terminal to all access points.

    Abstract: Reverse link busy bits are independently generated by each base station (102, 104 and 106) and indicative of whether the transmitting base station (102, 104 and 106) has reached a reserve link capacity limit. In a first exemplary embodiment, the remote station (122) combines the multipath components of the reverse link busy bits from each of the transmitting base stations (102, 104 and 106) in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations (102, 104 and 106) in the remote stations Active Set have reverse link capacity. In a first alternative embodiment, the remote station weights, the reverse link busy signals in accordance with the signal strength of the base station (102, 104 or 106) transmitting the busy signal and determines whether to transmit based on the weighted sum of the busy signals.

    Abstract: Un sistema de comunicación de datos inalámbrico que comprende: un recurso compartido (100) que comprende un canal (500) para comunicaciones de datos inalámbricos, y una pluralidad de usuarios (120), comprendiendo cada usuario un dispositivo configurado para transmitir de forma inalámbrica a una estación de base que utilice un recurso compartido, caracterizado por tener cada usuario uno o más vectores (130), comprendiendo cada vector un conjunto de elementos de vector, correspondiendo cada elemento de vector a una tasa de uso entre un conjunto de tasas de uso disponibles y representando una probabilidad de utilizar la tasa de uso correspondiente, en el que cada tasa de uso es una tasa de transmisión de datos para que un usuario transmita los datos hasta una estación de base, en el que una tasa de uso efectiva del recurso compartido asignado a cada usuario se selecciona en base al conjunto de elementos de vector.

    Abstract: In a system including a resource (100) which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.

    Abstract: When a resource of limited capacity is shared by several users, it is possible for the usage rates of the users to exceed the resource's capacity, thereby causing an overload condition. In a system or method according to an embodiment of the invention, at least some of the users have a set of persistence vectors. When an overload condition is detected, the usage rate of at least one of these users is changed, at least in part according to the user's set of persistence vectors.
