Abstract

See full text

A wireless communication device is disclosed for establishing communication with a remote terminal device through a cordless or a mobile base station. The wireless communication device has a cordless section and a mobile section. The cordless section is for communicating with a remote terminal device through the cordless base station in a cordless mode used for a cordless call. The mobile section is for communicating with the remote terminal device through the mobile base station in a mobile mode used for a mobile call. A processor of the wireless communication device detects a drop of a current call using the cordless service, for example, and re-establishes the communication using the mobile service. The user may be prompted prior to call re-establishment. For outgoing calls, the last dialled number is stored and re-dialled for call re-establishment. For incoming calls, the caller ID is used for call re-establishment. When a cheaper service is detected during a call, the user is prompted and invited to use the cheaper service.
