Benefits of technology

The present invention provides a user equipment that can efficiently connect to both Cellular and WLAN networks in a wireless communication system. It enables the device to select between different networks based on control over the cellular network.

Problems solved by technology

Yet, even if the multi-RAT user equipment is capable of accessing at least two RATs, it is unable to access a plurality of RATs at the same time.
In particular, currently, even if a user equipment has multi-RAT capability, it is unable to simultaneously perform data transmission / reception through different RATs.
Since all transmitted data are transmitted in a manner of being switched to another RAT, the related art multi-RAT technology has a problem in selecting an RAT suitable for characteristics of a flow.
However, a solution for this problem has not been proposed yet.

Embodiment Construction

[0038]Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. In the following detailed description of the invention includes details to help the full understanding of the present invention. Yet, it is apparent to those skilled in the art that the present invention can be implemented without these details. For instance, although the following descriptions are made in detail on the assumption that a mobile communication system includes 3GPP LTE / LTE-A system, the following descriptions are applicable to other random mobile communication systems in a manner of excluding unique features of the 3GPP LTE / LTE-A.

[0039]Occasionally, to prevent the present invention from getting vaguer, structures and / or devices known to the public are skipped or can be represented as block diagrams centering on the core functions of the structures and / or devices. Wherever possible, the same reference numbers w...

Abstract

A method of supporting signal transmission / reception using at least two RATs and apparatus therefor are disclosed. The present invention includes, when a user equipment is simultaneously accessing a 1st base station of a 1st communication network supportive of a 1st RAT and a 2nd base station of a 2nd communication network supportive of a 2nd RAT, receiving a setup message indicating a termination of a connection to the 2nd base station from the 1st base station and terminating the connection to the 2nd base station. Before the connection to the 2nd base station is terminated, the user equipment transceives data for a specific traffic type via the 2nd base station and also transceives data except the specific traffic type via the 1st base station. If the connection to the 2nd base station is terminated, the user equipment transceives the data for the specific traffic type via the 1st base station.

Description

[0001]Pursuant to 35 U.S.C. §119(e), this application claims the benefit of earlier filing date and right of priority to U.S. Application No. 61 / 676,312, filed on Jul. 26, 2012, No. 61 / 692,241, filed on Aug. 23, 2012, No. 61 / 693,759, filed on Aug. 27, 2012, No. 61 / 699,263, filed on Sep. 10, 2012, and No. 61 / 809,423, filed on Apr. 8, 2013, the contents of which are hereby incorporated by reference herein in their entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a wireless communication, and more particularly, to a method of supporting signal transmission and reception using at least two radio access technologies (RATs) and apparatus therefor.[0004]2. Discussion of the Related Art[0005]There may exist a multi-RAT user equipment having capability of accessing at least two radio access technologies (RATs). In order to access a specific radio access technology (hereinafter abbreviated RAT), a connection to the specific RAT is estab...
