Apparatus and method for deciding access system based on WLAN signal strength in WLAN/mobile network interworking system, and mobile terminal therefor
First Claim
1. A method for deciding an access system based on WLAN signal strength in a WLAN/mobile phone network interworking system, comprising:
- an initialization step for performing an initialization process on a WLAN driver module and a mobile 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; and
a service access step for enabling the corresponding driver module to access the service decided in the service decision step, wherein the service decision step comprises;
a first step for deciding whether the measured WLAN signal strength, value is greater than a reference value for setting a WLAN mode; and
a second step for enabling a WLAN driver module and disabling a mobile phone network driver, module when the measured value is greater than the reference value in the first step, and disabling the WLAN driver module and enabling the mobile network driver module when the measured value is smaller than the reference value;
wherein, in the service access step, when a communication mode of a terminal is a WLAN mode, if an average of N WLAN signal strength values measured for a predetermined period is smaller than a reference value, or if N1 (>
=N) WLAN signal strength values are all smaller than the reference value, the WLAN mode is converted into a mobile phone network mode.

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 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, and a service access step for enabling the corresponding driver module to access the service decided in the service decision step. 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.
