Abstract

A communication system is provided which includes: a portable terminal; a mobility management device that manages mobility of the portable terminal; a first gateway that connects the portable terminal to a first network; and a second gateway that connects the portable terminal to a second network. Based on a result of determining whether to connect the portable terminal to the first network via the first gateway or connect the portable terminal to the second network via the second gateway, the mobility management device switches between causing the portable terminal to use first contract information for connection to the first network via the first gateway and causing the portable terminal to use second contract information for connection to the second network via the second gateway.
