摘要： A gateway apparatus connects a packet-switched network to a PSTN, the packet-switched network having a plurality of information terminals connected thereto. The gateway apparatus includes a recognition operation, an incoming call notification operation and a connection operation. The gateway operates (or is configured) to recognize information terminals on the packet-switched network. The incoming call notification operation notifies all the recognized information terminals of an incoming call upon reception of an incoming call from the PSTN. The connection operation connects the PSTN to an information terminal that has responded to the incoming call notification first. An incoming call notification may be sent to all or a plurality of the information terminals on the packet-switched network in a point-to-multipoint communication using a broadcast address or a multi-cast address. Source-identifying information and destination telephone numbers on the PSTN may be allotted to the information terminals in advance so that the destination of an incoming call notification can be specified. Additionally, a telephone message recorder terminal may be used to receive incoming calls when no other terminal responds to the incoming call.

摘要： A mobile network system includes a guidance message control server, a call control server and access gateways. The call control server receives a call request notification from a first access gateway, determines whether a second access gateway is connected to a second mobile terminal, transmits a message transmission instruction to the guidance message control server and transmits a response message including a same group specifying information. The guidance message control server receives the message transmission instruction from the call control server, acquires guidance message data specified by a message specifying information and multicast transmits the guidance message data to a multicast group specified by the group specifying information. The first access gateway receives a call connection request from the first mobile terminal and transmits the call request notification to the call control server, performs multicast group participation processing for participating in the multicast group and transmits the guidance message data.

摘要： When a call is set between a first line switching network of a call-out side and a second line switching network of a call-in side, a first gateway, if receives a call setting message from the first line switching network, transmits a inquiry message to at least one of second gateway. Each of second gateway from which received the inquiry message transmits a response message to the first gateway when a second gateway itself can communicate a call setting message to the second line switching network. Thereafter, the first gateway selects a second gateway for transmitting the call setting message within the second gateways to which transmitted the response message, and transmits the call setting message to the selected second gateway.
