PROBLEM TO BE SOLVED: To provide a radio communication system in which a dropped call can be reconfirmed. SOLUTION: A switching system adjunct 120 monitors a call between a calling party and a party to be called and establishes the call when one of the parties has been dropped or is being dropped. The reestablishment is effected to a same or a different telephone number of the dropped party, and is effected via the same or a different medium (such as wired or radio). The call record of the original call is merged into the call record of the reestablished call, thus preserving the context of the entities included in the call which is present at the time that the party is dropped.
