Method of supporting signal transmission and reception using at least two radio access technologies and apparatus therefor

摘要

A method of supporting communication using two or more heterogeneous radio access technologies (RAT) comprises: receiving a setup message providing instructions for access to a second base station in a second communication network supporting the second RAT from a first base station in a first communication network supporting a first RAT; and attempting to access the second base station. At this time, when the terminal successfully accesses the second base station, specific traffic type data are transmitted and received through the second base station, and data other than the specific traffic type can be transmitted and received through the first base station.

1. A method of supporting signal transmission and reception using two or more radio access technologies (RATs) by a user equipment, comprising:
receiving a setup message indicating access to a second base station of a second communication network supporting a second RAT, from a first base station of a first communication network supporting a first RAT; and searching the second base station satisfying a predetermined condition; wherein the predetermined condition includes:
measured signal strength of the second base station is greater than measured signal strength of the first base station, ormeasured signal strength of the second base station is greater than a predetermined threshold, transmitting, to the first base station, a request message requesting access to the second base station of the second communication network, attempting to access the second base station, wherein if the access to the second base station is successfully performed, data on a specific traffic type is transmitted and received via the second base station, and data other than the specific traffic type is transmitted and received via the first base station.
