Systems, methods and devices for traffic offloading

摘要

Wireless communication traffic can be offloaded from a user equipment (UE) to two wireless points of access. For example, user equipment (UE) is connected to a radio access network (RAN) using a radio access technology (RAT) such as a long term evolution (LTE) network. The UE can determine which network capabilities are available for traffic offloading and adapt to the capabilities presented. In one embodiment, the UE can determine whether the network supports three different configurations and configure traffic offloading to operate within the network conditions: (1) RAN rules without access network detection and selection function (ANDSF), (2) ANDSF in conjunction with RAN rules or (3) enhanced ANDSF with RAN assistance.

主权项

1. A method for offloading cellular traffic to wireless local area network (WLAN) traffic, the method comprising:
receiving WLAN offload configuration data; receiving WLAN identifiers describing available wireless local area network access points (WLAN APs) for offload of data connections; determining WLAN parameters for received WLAN identifiers; receiving network provider rules that reference cellular parameters and the WLAN parameters; evaluating the network provider rules based on the cellular parameters and WLAN parameters to:
determine a set of access networks available for use;determine whether to connect to a WLAN AP in the set of access networks available for use; and when connecting to a WLAN AP, determine which data connections to offload to the WLAN AP.
