Abstract:
A UE and a method are described herein for optimizing a non-optimized handoff from a first access technology (e.g., E-TRAN, WiMAX, UMTS, WiFi, UMB and E-UTRAN) to a second access technology (e.g. 1×RTT, 1×EVDV, HRPD or eHRPD). In one embodiment, the “optimized” non-optimized handoff effectively decreases the mute time that is experienced by the UE during the handoff from the first access technology to the second access technology from around 628 ms to less than 500 ms which is a marked improvement.
