Problems solved by technology

If the target RAT such as the Global System for Mobile communications (GSM) Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network (GERAN) cannot support certain Internet Protocol (IP) capabilities, then the UE must turn on WLAN or WiFi and then transfer the IP traffic to Moved to WiFi, which takes longer and adversely affects user experience

Embodiment Construction

[0016] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0017] The current ANDSF policy preferred network list is static and is mainly used for initial network selection, so after the UE selects a higher priority network based on the policy, this network is usually always has higher priority. There is no mechanism to indicate a change in network priority based on changing conditions.

[0018] Embodiments provide optimized offload to WLAN in 3GPP RAT mobility. As used herein, the term "offload" refers to using a different service, such as WLAN for a specific service (eg, video streaming, data transfer, etc.) instead of...

Abstract

System and method embodiments are provided for optimizing offloading wireless services to a WLAN in 3GPP-RAT mobility. The embodiments enable changing network priority based on changing network conditions. In an embodiment, a method in a user equipment (UE) for offloading wireless services to a wireless local area network (WLAN) in a Third Generation Partnership Project (3GPP) inter-radio access technology (RAT) handover includes receiving an access network discovery and selection function (ANDSF) policy from an ANDSF server, wherein the ANDSF policy comprises policy rules including a validity condition, wherein the receiving is performed during a procedure in which the UE conducts an inter-RAT handoff from a first 3GPP RAT to a second 3GPP RAT; comparing evaluation condition information for the second 3GPP RAT against the validity condition; and offloading a first wireless service to the WLAN in accordance with the ANDSF policy when the validity condition is satisfied.

Description

[0001] Cross References to Related Applications [0002] The present invention claims U.S. Provisional Patent Application No. 61 / 754,295 filed on January 18, 2013 entitled "System and Method for Cellular to WLAN Offloading" and filed on January 13, 2014 entitled "Optimized Offloading to WLAN in 3GPP-RAT Mobility," which is hereby incorporated by reference as if reproduced in its entirety. technical field [0003] The present invention relates to systems and methods for wireless communications, and in particular embodiments, to systems and methods for cellular to WLAN offload. Background technique [0004] When a user equipment (UE) performs a 3rd generation partnership project (3GPP) inter-radio access technology (RAT) handover, it does not know the target RAT network capacity until it completes the power saving (PS) handover procedure. If the target RAT such as the Global System for Mobile communications (GSM) Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Netwo...
