Embodiment Construction

[0035] The techniques described below can be used in various wireless communication systems such as Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), etc. CDMA can be implemented in a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA-2000. TDMA can be implemented in a radio technology such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data rates for GSM Evolution (EDGE). OFDMA can be implemented in radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, Evolved UTRA (E-UTRA), and the like. IEEE802.16m evolves from IEEE802.16e, and provides backward compatibility with IEEE802.16e-based systems. UTRA is part of the Universal Mobile Telecommunicati...

Abstract

A method and apparatus for transmitting an indication in a wireless communication system is provided. A user equipment (UE) transmits / receives traffic with a second network, and transmits an indication, which includes information on the traffic in the second network, to a first network. For traffic steering, the UE may determine whether the traffic is to be offloaded from the second network to a first network or not, and if it is determined that the traffic is to be offloaded from the second network to the first network, the indication may further include a cause value corresponding to offloading.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and device for sending service indications in a wireless communication system. Background technique [0002] Universal Mobile Telecommunications System (UMTS) is a third generation (3G) asynchronous mobile communication system operating in Wideband Code Division Multiple Access (WCDMA) based on the European system, Global System for Mobile Communications (GSM) and General Packet Radio Service (GPRS) . Long Term Evolution (LTE) of UMTS is under discussion through the 3rd Generation Partnership Project (3GPP) that standardizes UMTS. [0003] 3GPP / Wireless Local Area Network (WLAN) interactions have been discussed. 3GPP / WLAN switching may be referred to as service oriented. From Release 8 of 3GPP LTE, the Access Network Discovery and Selection Function (ANDSF) for detecting and selecting accessible access networks has been standardized while introducing interact...
