PoC DATA TRANSMITTING METHOD AND PoC TALKING SYSTEM AND DEVICE
A PoC data transmitting method of distributing attached data used to realize a PoC attached function in conformity with a PoC protocol is provided. A PoC data transmitting method includes a first step of attaching attached data (set information) to a first message that is transmitted to a PoC server from a transmitter side terminal (PoC client 1 ) based on a PoC protocol, and transmitting the set information as well as the first message to the PoC server from the PoC client 1 , and a second step of attaching the set information to a second message that is transmitted to one or plural receiver side terminals (PoC clients 2,3 ) from the PoC server that received the first message based on the PoC protocol, and transmitting the set information as well as the second message to the PoC clients 2,3 from the PoC server. According to this PoC data transmitting method, the attached data can be transmitted by utilizing the message transmitted according to the PoC protocol, and a PoC attached function can be realized.

a second step of attaching the attached data to a second message that is transmitted to one or plural receiver side terminals from the PoC server that received the first message based on the PoC protocol, and transmitting the attached data as well as the second message to the receiver side terminal from the PoC server.
2 . The PoC data transmitting method according to claim 1 , wherein the first message and the second message are a message that is transmitted in opening, changing, or closing a session based on the PoC protocol.
3 . The PoC data transmitting method according to claim 2 , wherein the first message and the second message are an SIP message.
4 . The PoC data transmitting method according to claim 3 , wherein the first message is a talk start request (INVITE) message, and the second message is the talk start request (INVITE) message transferred from the PoC server.
5 . The PoC data transmitting method according to claim 3 , wherein the first message is a PoC start notice (REGISTER) message, and the second message is the talk start request (INVITE) message transferred from the PoC server.
6 . The PoC data transmitting method according to claim 3 , wherein the first message is a talk start response (INVITE response) message, and the second message is a presence information notice (NOTIFY) message.
7 . The PoC data transmitting method according to claim 3 , wherein the first message is a talk refuse notice (BUSY) or talk leave notice (BYE) message, and the second message is a presence information notice (NOTIFY) message.
8 . The PoC data transmitting method according to claim 1 , wherein the first message is a message that is transmitted to the PoC server from a terminal that wishes to take a floor, and the second message is a message that is transmitted from the PoC server to other servers to notify other servers that the PoC server took the floor.
9 . The PoC data transmitting method according to claim 8 , wherein the first message and the second message are transmitted by a RTCP packet, and an SDES packet containing the attached data is attached to the RTCP packet and transmitted.
10 . A mobile terminal, comprising:
an inputting portion which inputs or designates attached data;
an attached message generating portion which attaches the attached data to a message that is transmitted to a PoC server based on a PoC protocol; and
a displaying portion which displays data attached to the message that is sent from the PoC server based on the PoC protocol.
11 . A PoC server, comprising:
an attached message processing portion which analyzes attached data attached to a message that is sent from a transmitter side terminal based on a PoC protocol; and
an attached message generating portion which attaches the attached data to a message that is transmitted to one or plural receiver side terminals based on the PoC protocol.
12 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein the transmitter side terminal transmits information indicating a speakable terminal and an attend-only terminal as the attached data in opening a session such that the speakable terminal and the attend-only terminal are designated by the transmitter side terminal.
13 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein a terminal that refuses an attendance in a PoC talking or a terminal that leaves from the PoC talking transmits information of a reason for attendance refusal or a reason for leave as the attached data, and the terminal that received the attached data displays the reason for attendance refusal or the reason for leave.
14 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein the transmitter side terminal transmits data of an acknowledge sound as the attached data in opening a session or in taking a floor, and the receiver side terminal uses the acknowledge sound transmitted from the transmitter side terminal as an acknowledge sound to acknowledge an operation of the transmitter side terminal.
15 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein the transmitter side terminal transmits a user icon or BGM data as the attached data in opening a session, and the receiver side terminal displays the user icon or the BGM transmitted from the transmitter side terminal when the transmitter side terminal takes a floor.
16 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein the transmitter side terminal transmits an original message as the attached data in taking a floor, and the receiver side terminal displays the original message transmitted from the transmitter side terminal while the transmitter side terminal holds the floor.
17 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein the transmitter side terminal transmits an icon selected from a plurality of icons as the attached data in taking a floor, and the receiver side terminal displays the icon transmitted from the transmitter side terminal while the transmitter side terminal holds the floor.
18 . A PoC talking system in which a first message to which attached data is attached is transmitted from a transmitter side terminal to a PoC server based on a PoC protocol and a second message to which the attached data is attached is transmitted from the PoC server to a receiver side terminal based on the PoC protocol,
wherein the transmitter side terminal transmits information of a floor release time as the attached data in taking a floor, and the receiver side terminal displays a countdown based on the information of the floor release time transmitted from the transmitter side terminal.
