Document Type and Number:
Japanese Patent JP2008547268
Kind Code:
A
Abstract:
A method and communication system for supporting dormant mode are described. In one embodiment, the communication system comprises a wireless station operable in a power savings mode and group of access points. Each group of access points comprises one or more access points with at least one group of access points having at least two access points. Ranges for the one or more access points in each of the groups define a paging area for each group, wherein one access point uses a paging channel for paging the wireless station when the wireless station is in the power savings mode and is in the paging area associated with the one access point. The wireless station performs a handoff procedure when the one access point is not in the same group of access points as the access point associated with the wireless station prior to the wireless station entering the power savings mode and does not perform a handoff procedure when the one access point is in the same group of access points as the access point associated with the wireless station prior to the wireless station entering the power savings mode.
