Abstract

The present invention discloses an apparatus and method for deciding an access system based on WLAN signal strength in a WLAN / mobile phone network interworking system, and a mobile terminal (FIG.2) therefor. The method for deciding the access system based on the WLAN signal strength in the WLAN / mobile phone network interworking system includes an initialization step for performing an initialization process on a WLAN driver module and a mobile phone network driver module, and measuring and displaying WLAN signal strength, a service decision step for selecting a WLAN service or mobile phone network service according to the measured WLAN signal strength (S103,S107), and a service access step for enabling the corresponding driver module to access the service decided in the service decision step (S104,S108). The apparatus and method for deciding the access system based on the WLAN signal strength provide a roaming service by efficiently interworking a WLAN which provides a high speed internet access service based on hot spots and a mobile phone network which provides a national communication service, to facilitate activation of the wireless internet service.

Description

technical field [0001] The present invention relates to a device and a method for judging an access system according to WLAN signal strength in a WLAN / mobile network interworking system, in particular to a device for judging an access system according to WLAN signal strength in such a WLAN / mobile network interworking system and method, that is, the intercommunication system can provide roaming services through the intercommunication between WLAN and mobile network, WLAN provides high-speed wireless Internet access services based on hotspots, and mobile network provides domestic communication services. Background technique [0002] WLAN is a system designed to provide high-speed wireless data services based on Ethernet. It has been used as a network solution for cable-free places such as factories, meeting rooms and exhibition halls. [0003] WLAN provides cheap service equipment by partially restricting terminal mobility, thereby reducing network construction costs and impr...
