Abstract: A system includes an enterprise network having a call control system that manages telephony services for wireless handsets. At a remote site, a computing device establishes a secure, wireline communication session with the enterprise network. The computing device also establishes wireless, packet-based links with one or more handsets. The device acts as a relay to enable the handsets to receive telephony services managed by the enterprise network even though outside of the service area of the enterprise network.

Abstract: A system (10) includes an enterprise network (12) having a call control system (26) that manages telephony services for wireless handsets (20). At a remote site (16) a computing device (22) establishes a secure, wireline communication session with the enterprise network (12). The computing device (22) also establishes wireless, packet-based links with one or more handsets (20). The device (22) acts as a relay to enable the handsets to receive telephony services managed by the enterprise network (12) even though outside of the service area of the enterprise network (12).

Abstract: A method includes identifying a plurality of communication channels at a wireless device and classifying each of the communication channels into one of a plurality of groups. The method also includes scanning the communication channels in the groups. The communication channels in at least one of the groups are scanned at a different frequency than the communication channels in at least one other of the groups. In addition, the method includes updating one or more of the groups based on the scans.
