A method and apparatus adaptively scan communication channels to find a channel having a desired attribute such as being usable for communication with a home network in one of a plurality of communication modes. A first scan of a first set of channels is performed, and attributes are assigned to channels. If a channel having the desired attribute is not found, the attributes are used to configure a second scan of a second set of channels using a second scan mode, such that the expected amount of resources consumed in the second scan is reduced, for example by scanning channels more likely to be usable for communication first. The second scan of a second set of channels is performed, and additional attributes are assigned to channels. If a channel having the desired attribute is found during the first or second scan, the scan may terminate.

Method and apparatus for scanning multi-mode wireless communication environments

The present invention provides a method for managing communications of a wireless device in a wireless communication system based on network traffic level, and a wireless device comprising a control system configured to evaluate a network traffic level. The wireless device may be configured to transmit data, such as delay-tolerant data, based upon the network traffic level, for example transmitting data only under low traffic conditions. Deferring delay-tolerant communications may result in lower peak traffic conditions in the network. Evaluating the network traffic level may comprise measuring chip energy over total energy (Ec/Io), monitoring data on shared control channels such as HS-SCCH of a HSDPA system, inferring power allocated to channels by a dynamic power allocation scheme, or other methods.

The present invention provides a method and system for performing position area updates in a wireless communication system configured to broadcast a plurality of position area codes, each associated with one of a plurality of position areas. The method comprises moving the wireless terminal from a first position area to a second position area; evaluating a predetermined condition; and performing the position area update when the predetermined condition is met.
