Improvements in mobile communication devices

摘要

During initiation of a call, a calling mobile telephone determines the status of a called mobile telephone from data sent from the called mobile telephone or from a server database in the network. The status information may comprise a unique code which defines the call alert mode set in the called mobile telephone. The call alert mode may be one or more of musical tones, vibrating alert or lighting indicator. The calling mobile telephone may be arranged to imitate the call alert of the called mobile telephone. The caller is thus made aware of the ring tone set in the called mobile telephone and may purchase the ring tone if desired.
