Abstract: Methods and apparatus for out of service processing with varied behaviors. In an aspect, a method is provided for service acquisition. The method includes determining one or more conditions, wherein each condition is associated with at least one weight, detecting whether an out-of-service event has occurred, and if an out-of-service event is detected: identifying selected conditions and associated weights, and processing the associated weights to determine service acquisition “on” and “off” times. In an aspect, an apparatus includes condition logic configured to determine one or more conditions, wherein each condition is associated with at least one weight, and processing logic configured to detect whether an out-of-service event has occurred, and if an out-of-service event is detected, to identify selected conditions and associated weights, and process the associated weights to determine service acquisition “on” and “off” times.

Abstract: Techniques to support cell reselection from GSM to W-CDMA. A dual-mode terminal determines whether or not the GSM network that it is currently camped on supports Release 99 functionality and hence whether or not the GSM network is capable of broadcasting information for W-CDMA neighbor cells. This determination may be made based on the settings for certain status bits in messages transmitted by the GSM network and/or other information available to the terminal. The terminal can initiate a search for W-CDMA cells if it is deemed that the current GSM network does not support Release 99 functionality. The terminal may also determine the scope of the W-CDMA search and when to perform the W-CDMA search based on information stored by the terminal. The reselection from GSM to W-CDMA may be achieved based on measurements obtained from the W-CDMA search and other pertinent information (e.g., threshold values used to compare the measurements).

Abstract: This disclosure is directed to a technique for efficient inter-RAT (Radio Access Technology) cell reselection in a wireless communication system. In general, following an unsuccessful cell reselection attempt, the technique involves upgrading one or more cell selection criteria for the pertinent cell. By upgrading the cell reselection criteria, requirements for reselection of the cell in the future are made more stringent. The technique may promote more efficient cell reselection performance, thereby reducing the frequency of repeated, unsuccessful reselection attempts for the same cell. In this manner, the technique can be effective in reducing power consumption and computational overhead incurred by unsuccessful cell reselection attempts, thereby increasing standby time in a wireless communication device. The technique may be implemented within a wireless communication device that supports two or more RAT types, such as WCDMA and GSM.

Abstract: Various method and apparatus provides for matching revision levels used by a mobile station (102-104) and a base station (101, 160) for establishing a communication link. The mobile station repeats, for a number of times, the transmission of a request for establishing a communication link between the mobile station and the base station. The mobile station detects failure of establishing the communication link with the first revision level based on repeating the request for the number of times. The mobile station changes the first revision level to the second revision level at the mobile station for establishing the communication link.
