Abstract
The present invention provides a mobile communication network system comprising a first mobile communication network having a plurality of routers, a second mobile communication network having a plurality of routers, and a mobile communication terminal. A router located in an end section of a communication area of the first mobile communication network sends an end message indicating that it is located in the end section, to the mobile communication terminal. The terminal initiates communications with a router of the second mobile communication network, whilst the terminal is communicating with the router located in the end section, upon receiving the end message sent by the router located in the end section.
