WIRELESS COMMUNICATION METHODS AND APPARATUS SUPPORTING PAGING AND PEER TO PEER COMMUNICATIONS
First Claim
1. A communications method comprising:
- operating a first wireless terminal capable of supporting peer to peer mode operations and cellular network operations, said operating a first wireless terminal including;
monitoring for paging signals from a base station during a first set of time intervals which are paging time intervals; and
during a second set of time intervals which do not overlap said first set of time intervals participating in a peer to peer communications session.

Abstract
Methods and apparatus supporting efficient paging in a wireless communications system supporting both access node based communications and peer to peer communications are described. Paging timing intervals are set aside in the timing structure such that multi-mode wireless terminals can monitor, e.g., in an infrastructure band, for pages from a base station whether the wireless terminal is operating in a base station attachment point mode or is operating in a peer to peer communications mode. Wireless terminals operating in a peer to peer mode, e.g., using a non-infrastructure band, suspends peer to peer communications during the paging intervals. The time periods, in which the wireless terminal checks pages are, in some embodiments, predetermined, so that both the wireless terminal and base station are synchronized on when a page should be delivered. This synchronization helps reduce the wastage of session time in the peer to peer sessions.
