Un procedimiento (1700) para las comunicaciones inalámbricas en un punto de acceso, AP, que comprende: determinar (1710) si se borra una cobertura de control de velocidad de datos, DRC, transmitida desde un terminal de acceso, AT; determinar (1730) si se cumplen los criterios de borrado de cobertura en relación con la cobertura DRC, si se borra la cobertura DRC; determinar (1740) si se borra un valor de control de fuente de datos, DSC, transmitido desde el terminal de acceso, si se cumplen los criterios de borrado de cobertura; multidifundir (1760) trafico directo al AT desde una pluralidad de sectores que están en la célula servida por el punto de acceso y en un conjunto activo del AT, si se borra el valor DSC; y programar (1720) la transmisión del AT desde un sector asociado con la cobertura DRC, si no se borra la cobertura DRC. 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.
