SYSTEMS, METHODS AND DEVICES FOR TRAFFIC OFFLOADING
First Claim
1. A mobile device comprising:
- a mobile broadband (MBB) interface for connecting to 3rd generation partnership project (3GPP) networks;
a wireless network interface for connecting to non-MBB networks; and
a processor configured to execute instructions that cause the mobile device to;
determine a MBB network configuration for processing offload rules;
configuring the mobile device to use offload rules compatible with the MBB network configuration;
determine whether to offload traffic between the MBB interface and the wireless network interface based on the configured offload rules; and
when determined to offload, determining which connections to offload between the MBB interface and the wireless network interface.

Abstract
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.
