Abstract

Methods and apparatus for providing inter-RAT mobility between 2G/3G and 4 networks are described. A UE camped or connected to a GERAN or UTRAN network may be configured to move, either directly or through network-controlled functions, to an LTE network to perform a data call. The UE may then return to a 2G/3G network.

Description

technical field [0001] This application relates generally to wireless communication systems. More specifically, but not exclusively, the present application relates to a method for providing inter-radio access technology (RAT) mobility between 2G / 3G networks such as GERAN and UTRAN networks and 4G networks such as LTE networks systems, devices and methods. Background technique [0002] Wireless communication systems have been widely deployed to provide various types of communication content such as voice, data, video, etc., and with the introduction of new data-oriented systems such as Long Term Evolution (LTE) systems, the deployment is likely to increase. A wireless communication system may be a multiple-access system capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (T...
