Abstract
A multimode mobile telephone terminal (T1) allowing the transfer of a telephone call from one wireless network to another, comprising: an interface (CSI) for supporting circuit-switched calls, an interface (PSI) for supporting packet-switched calls, a call transfer manager (HOM) for deciding on call transfers, an access monitor (ACM) for activating or deactivating the devices (D1-D4, . . . etc.) that said interfaces (CSI and PSI) comprise, based on: information on the state of those devices' availability, the type and state of the radio connectivity offered by the terminal, and preferences defined by a user or mobile fleet administrator; a call manager (CH) for: managing the calls presented to the user based on the current status of each of the devices (D1-D4 . . . etc.) that the interface (CSI) comprises to support circuit-switched calls, and that the interface (PSI) comprises to support packet-switched calls, and managing the switchover of a multimedia session, should the need arise, from one device (D1-D4 . . . etc.) to another based on signals from the call transfer manager (HOM); This call manager (CH) comprises an abstraction layer (AL) that makes it possible to exchange gene…
