Abstract

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.

Claims9

Dependent claims

A mobile network system comprising:

a guidance message control server;
a call control server;
and
a plurality of access gateways each of which is connected to a mobile terminal via a wireless base station,
wherein the call control server includes,
a receiving section that receives from a first access gateway included in the plurality of access gateways a call request notification that a first mobile terminal has made a call request for a second mobile terminal,
a determination section that determines whether a second access gateway that is included in the plurality of access gateways and is connected to the second mobile terminal specified in the call request notification received by the receiving section is call-restricted,
an instructing section that transmits a message transmission instruction including message specifying information and group specifying information to the guidance message control server, and
a response section that, in a case where the determination section determines that the second access gateway is call-restricted, transmits a response message including the same group specifying information as that included in the message transmission instruction to the first access gateway,
wherein the guidance message control server includes,
an instruction receiving section that receives the message transmission instruction from the call control server,
an acquisition section that acquires guidance message data specified by the message specifying information included in the message transmission instruction received by the instruction receiving section, and
a transmission section that multicast transmits the guidance message data acquired by the acquisition section to a multicast group specified by the group specifying information included in the message transmission instruction received by the instruction receiving section, and
wherein the first access gateway includes,
a relay section that receives from the first mobile terminal via the wireless base station a call connection request for the second mobile terminal and transmits the call request notification to the call control server in response to the call connection request,
a processing section that, in a case where the processing section receives the response message from the call control server, performs multicast group participation processing for participating in the multicast group specified by the group specifying information included in the response message, and
a guidance transmission section that transmits the guidance message data that is received as a result of the multicast group participation processing performed by the processing section to the first mobile terminal.

14 more elements

A guidance message providing method performed in a mobile network system including a guidance message control server, a call control server, and a plurality of access gateways each of which is connected to a mobile terminal via a wireless base station, the guidance message providing method comprising:

causing the call control server,
to receive from a first access gateway included in the plurality of access gateways a call request notification that a first mobile terminal has made a call request for a second mobile terminal,
to determine whether a second access gateway that is included in the plurality of access gateways and is connected to the second mobile terminal specified in the received call request notification is call-restricted,
to transmit a message transmission instruction including message specifying information and group specifying information to the guidance message control server, and
to, in a case where it is determined that the second access gateway is call-restricted, transmit a response message including the same group specifying information as that included in the message transmission instruction to the first access gateway;
causing the guidance message control server,
to receive the message transmission instruction from the call control server,
to acquire guidance message data specified by the message specifying information included in the received message transmission instruction, and
to multicast transmit the acquired guidance message data to a multicast group specified by the group specifying information included in the received message transmission instruction;
and
causing the first access gateway,
to receive from the first mobile terminal via the wireless base station a call connection request for the second mobile terminal and transmit the call request notification to the call control server in response to the call connection request,
to, in a case where the response message is received from the call control server, perform multicast group participation processing for participating in the multicast group specified by the group specifying information included in the response message, and
to transmit the guidance message data that is received as a result of the multicast group participation processing to the first mobile terminal.
