Methods and apparatuses are provided that facilitate avoiding one or more wireless communication systems based at least in part on determining a level of unreliability of a reverse link channel related to a system. This can be based at least in part on determining whether the system can be accessed over the reverse link channel. If not, the wireless communication system can be avoided to conserve power utilized to perform such access attempts. Where the unreliability is temporary, however, some access attempts can be performed for systems of higher priority than a current system during the period of avoidance of one or more higher priority systems.

Method and apparatus for selecting wireless communication systems

Systems and methodologies are described that facilitate apportioning a radio link failure (RLF) recovery timer among a plurality of radio access technologies (RAT). Once RLF is determined, a RLF recovery timer can be obtained and split according to a timer allocation. The timer allocation can include equal or weighted percentages related to the plurality of RATs, and a timer can be split according to the percentages to attempt connection using a RAT during a corresponding portion of the timer. In addition, the timer allocation can be defined according to a type of communication. In this regard, for voice calls, the timer can be split among circuit-switched networks regardless of a network from which connection is lost, and/or the like. Moreover, the timer allocation can be defined based on RAT deployment characteristics.
