Abstract
Systems and methodologies are described that facilitate reducing battery consumption during periods of inactivity intermixed with traffic bursts in wireless communications systems. A semi-connected mode is provided that fast recognition of mobile devices upon wakeup and access while enabling mobile devices to operate in reduce power states. A mobile device operates in a semi-connected mode with all base stations in an active set of the mobile device. Moreover, mechanisms are provided to notify mobile devices of pending data while avoiding latency associated with paging channels.
Claims64
A method of operating a mobile device in a wireless communications system, comprising:
- initiating a semi-connected mode with one or more base stations in an active set in which the mobile device sends a semi-connected start message, retains a MAC ID that enables expedited system access, and enters a sleep state;
- operating in the semi-connected mode in which the mobile device wakes at scheduled intervals to monitor for a forward link assignment block, wherein the forward link assignment block is employed as a page mechanism that bypasses traditional paging channels to provide expedited system access;
- and
- exiting the semi-connected mode on receipt of the forward link assignment block on a shared signaling channel.

A wireless communications apparatus, comprising:
- a memory that stores instructions related to:
- initiating a semi-connected mode with one or more base stations in an active set in which a mobile device sends a semi-connected start message, retains a MAC ID that enables expedited system access, and enters a sleep state;
- operating in the semi-connected mode in which the mobile device wakes at scheduled intervals to monitor for a forward link assignment block, wherein the forward link assignment block is employed as a page mechanism that bypasses traditional paging channels to provide expedited system access;
- and
- exiting the semi-connected mode on receipt of the forward link assignment block on a shared signaling channel;
- and
- a processor coupled to the memory, configured to execute the instructions retained in the memory.
