发明名称 Mobile radio communications method and mobile subscriber terminal
摘要 A mobile radio communications method that prevents a calling user from being billed for an expensive overseas call, which the user could make without knowing that the destination mobile terminal is currently roaming abroad. When a mobile terminal has moved from a first country to a second country, its home mobile switch is informed of the new terminal location. The home mobile switch consults this location information when a call request to the roaming mobile terminal is placed by another mobile terminal, so as to determine in which country the destination is. If it turns out to be in the second country, the home mobile switch so notifies the calling mobile terminal by sending an overseas destination notice to it. This notice warns the calling user that he/she is making eventually an international call, thus allowing him/her to reconsider whether to proceed with the call request or cancel it.
