Problems solved by technology

The latter problem is that offloading should be done at the APN or IP flow level first, but in the current 3GPP architecture, RAN has no knowledge of APN or IP flow

Embodiment Construction

[0024] Now please refer to some detailed embodiments of the present invention in conjunction with the drawings.

[0025] figure 1 A schematic diagram of a mobile communication network 100 selected for use offloading according to a new aspect. RAN is a part of a mobile telecommunication system that implements radio access technology. In most geographic areas, there are usually multiple radio access networks available for the user equipment UE101 to access the information source 110 (for example, the Internet) and obtain mobile data services. Examples of different RAN types are GSM radio access network, UTRA or E-UTRA cellular access network, WiMAX system and WLAN (also called WiFi). If multiple RANs support the same air interface, all access networks are homogeneous networks (homogeneous networks). From the UE perspective, as long as the data service remains fast and high-quality, it does not matter through which access network the required information is delivered.

Abstract

A method of offload selection for a UE to select between 3GPP RAT and WLAN cell is provided. The UE receives configuration information that applies to selecting WLAN or 3GPP radio access technology (RAT). The UE determines if the UE may perform WLAN offload by evaluating 3GPP radio access network (RAN) conditions where at least one RAN condition is related to a radio signal strength or a radio signal quality in 3GPP RAT. The UE then determines if there is at least one suitable WLAN cell by evaluating WLAN conditions. The UE also determines if there is candidate traffic for WLAN offload. Finally, the UE steers the determined traffic to WLAN if the UE may perform WLAN offload and if there is at least one suitable WLAN cell. Otherwise, the UE steers the determined traffic to 3GPP RAT.

Description

[0001] Cross references to related applications [0002] This application claims the priority of the U.S. provisional application filed on January 29, 2014 named "Offload Selection" and numbered 61 / 932,825 under 35 U.S.C. 119 (35USC.§119) , The entire content of the application is quoted here. Technical field [0003] Various embodiments of the present invention are related to wireless network communication, and more specifically, to the function of interworking between cellular wireless communication and wireless local area network (Wireless Local Area Network, WLAN) (also referred to as WiFi) communication. Background technique [0004] In order to meet the rapidly increasing demand for mobile data services, various network operators are developing new technologies and defining new standards for next-generation wireless communication networks to achieve higher peak transmission rates. For example, the International Telecommunication Union Radio Communications Sector (ITU-R) stipu...
