Providing and maintaining F-PDCH service in a mobile communication system
First Claim
1. A method for providing forward link packet data service to mobile stations (MSs) in a mobile communication system, the method comprising:
- providing, by a cell in the mobile communication system, data transmission services via a forward link;
indicating to an MS that the cell will not provide data transmission service to the MS via the forward link.

Abstract
Various embodiments are described herein to address the need for providing and maintaining F-PDCH service to an MS (103). Upon receiving an indication that the MS intends to switch from a F-PDCH of a serving cell (132) to a F-PDCH of a target cell (142) for continued data transmission service, the network equipment (e.g., BSs 120, 130, and/or 140) determines whether the target cell is presently available to provide the F-PDCH service to the MS. When the selected cell is not able to support F-PDCH service for the MS (e.g., because of F-PDCH loading, quality of service requirements, etc.), the network equipment sends an indication to the MS that the target cell is presently unavailable to provide F-PDCH data transmission service to the MS. Thus, the MS is able to abort switching to the selected cell and prevent loosing its F-PDCH service as a result.
