First Claim
1. A mobile phone terminal connectable with a group call system that performs a group call in which a phone call among a plurality of mobile phone terminals is performed, the mobile phone terminal comprising:
- a receiver that receives, through a line switching network, an address registration request message including group call identification information identifying the group call and requesting address registration in a server provided in a packet switching network;
a storage unit that stores the group call identification information included in the address registration request message received through the line switching network, as a received call history; and
a processor that accepts calling operation for the group call corresponding to the group call identification information stored as the received call history, whereinthe processor acquires from the storage unit the group call identification information associated with the group call for which the calling operation has been accepted,the processor transmits halfway participation calling information including the acquired group call identification information, andthe mobile phone terminal joining the group call halfway does not correspond to an initial formation of the group call.
