  • Unbroken primary connection switching between different communication services
    Publication number: 20050143053
    Abstract: A method allows a user of a mobile terminal to switch from a communication service currently active between that mobile terminal and another mobile terminal to a different communication service in such a manner that the end to end connection between terminals appears unbroken to the user. The user initiates the switch by inputting an appropriate command at the mobile terminal. The mobile terminal then transfers a request to the other mobile terminal. The request invokes a user interface on the other mobile terminal and prompts the user of the other mobile terminal to indicate whether or not they agree to switch from the currently active communication service to the other communication service. After receiving the user's response to the prompt, the other mobile terminal sends back a reply indicating the user's response. Signaling to perform the switch is initiated in response to the reply.
