Abstract:
1. A method for offloading non-voice traffic, the method comprising: receiving, at a user equipment (UE) connected to an E-UTRAN, a Circuit Switched (CS) Service Notification from an eNodeB, wherein the UE supports Multi-Access Packet Data Network Connectivity (MAPCON) and Internet Protocol Flow Mobility and Seamless Offload (IFOM), and wherein an Inter System Routing Policy (ISRP) is stored in the UE; connecting to a UTRAN as a result of a handover procedure triggered by the CS Service Notification; offloading non-voice traffic to a WLAN based on the ISRP; connecting to an E-UTRAN as a result of a handover procedure; re-routing the non-voice traffic through the E-UTRAN if it is determined that a timer has expired; and maintaining the offloading of the non-voice traffic through the WLAN if it is determined that the timer has not expired.
