Network system, terminal, and notification method

A terminal capable of communicative connection to any one of base stations in multiple respective networks via radio communication,

• first identification information capable of identifying each of the multiple networks being configured in advance,
• the terminal comprising:
• a receiver configured to receive emergency information associated with the first identification information from a base station of the base stations in a case that the terminal exists in a radio communication service area of the base station regardless of whether the terminal is communicatively connected to the base station;
• and
• a controller configured to configure, in a case that the receiver receives the emergency information, only the emergency information received from a network of the multiple networks to which the terminal is communicatively connected as a notification target, based on the first identification information associated with the emergency information.

A notification method of emergency information in a network system, the network system including base stations in multiple respective networks, and a terminal capable of communicative connection to any one of the multiple networks via radio communication,

• first identification information capable of identifying each of the multiple networks being configured in advance,
• the notification method comprising the steps of:
• transmitting, by a base station of the base stations, emergency information to the terminal existing in a radio communication service area of the base station to allow the emergency information to be received by the terminal regardless of whether the terminal is communicatively connected to the base station, the emergency information being associated with the first identification information configured for a network of the multiple networks to which the base station is communicatively connected;
• receiving, by the terminal, the emergency information associated with the first identification information from the base station;
• and
• configuring, by the terminal and in a case that the emergency information is received, only the emergency information received from the network to which the terminal is communicatively connected as a notification target, based on the first identification information associated with the emergency information.
