Methods and apparatus to handle bearers during circuit switched fallback operation

摘要

Methods and apparatus to provide packet switched service continuity during circuit switched fallback operation are described. One example method includes determining a set of access technologies available to a User Equipment (UE); identifying a WLAN access network from the set of access technologies; identifying a 3GPP RAT from the set of access technologies; prioritizing the WLAN access network type with respect to types of 3GPP RAT; and selecting one access technology from amongst the identified WLAN access network and the 3GPP RAT according to the prioritizing.

1. A method comprising:
determining a set of access technologies available to a User Equipment (UE); identifying a WLAN access network from said set of access technologies; identifying a 3GPP RAT from said set of access technologies; prioritizing the WLAN access network type with respect to types of 3GPP RAT for a user plane handover during a circuit switch fall back (CSFB) procedure based at least in part on a target RAT in the CSFB procedure; and during the CSFB procedure, selecting one access technology from amongst said identified WLAN access network and said 3GPP RAT according to said prioritizing for the user plane handover.
