    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: 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.

    Abstract: A method for controlling transmission power of a remote station (122) in a soft handoff condition is provided. The method comprises receiving at the remote station (122) a power control command transmitted by each of the plurality of base stations (102, 104, 106), and increasing transmission energy of the remote station (122) only when each of the power control commands transmitted by the base stations in an Active Set of the remote station (122) requests an increase in the remote station transmission energy.

    Abstract: A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal. The beams that should be used are the beams that if used will decrease the call dropping rates and provide a desired level of beam source diversity.
