US 10,122,633 B2 · Method and apparatus for effective wireless LAN selection

Abstract

A method for selecting an access network in a terminal of a mobile communication system according to one embodiment of the present specification comprises the steps of: if traffic is generated in the terminal, selecting an access network according to the characteristics of the generated traffic and network selection policy information; and transmitting and receiving the generated traffic via the selected access network. According to the embodiment, the present invention adjusts priorities of accesses given to users and applications in a wireless communication system including heterogenerous networks, thereby reducing processes for reselecting an access network of a user terminal, and reducing the cases of unnecessarily accessing a network having a low priority or requiring high costs for a long time. Therefore, the present invention can enhance user convenience and improve communication efficiency.

Dependent claims

A method by a terminal in a wireless communication system, the method comprising:

discovering at least one available wireless local area network (WLAN);
identifying a first policy related to a WLAN selection;
generating a prioritized list of the at least one available WLAN based on the first policy;
selecting a WLAN with a highest priority from the prioritized list based on the first policy;
identifying an access network between the selected WLAN and a cellular network based on a second policy acquired from a network entity;
routing an internet protocol (IP) flow over the identified access network;
identifying a new internet protocol (IP) flow;
and
omitting a WLAN reselection if a highest priority access network corresponding to the new IP flow based on the second policy is a WLAN other than the selected WLAN.
