Communication terminal device and method for controlling
First Claim
1. A communication terminal device comprising:
- first circuitry to communicate with a group communication server, the first circuitry to receive a session initiation protocol (SIP) invite from the group communication server, the SIP invite to request initiation of group communication between a plurality of communication terminal devices;
a controller, coupled with the first circuitry, to modify the SIP invite; and
second circuitry, coupled with the controller, to provide device-to-device communication, the second circuitry to transmit the modified SIP invite to another communication terminal device of the plurality of communication terminal devices,wherein the controller is to set a first on-hold status of the other communication terminal device to off hold at the communication terminal device and is further to transmit a message, via the first circuitry, to the group communication server to set a second on-hold status of the other communication terminal device to on-hold at the group communication server.

Abstract
In various aspects of this disclosure, a communication terminal device may be provided. The communication terminal device may include a receiver. The receiver may be configured to receive a message from a first communication device. The communication terminal device may further include a circuit configured to provide a communication device to communication device communication. The communication terminal device may further include a controller. The controller may be configured to determine whether to relay the received message to at least one second communication device. The controller may further be configured to modify the message if the controller determined to relay the received message. The controller may further be configured to relay and transmit the modified message to the at least one second communication device.

10. One or more non-transitory, computer-readable media having instructions that, when executed, cause a communication terminal device to:
-
process a session initiation protocol (SIP) invite received from a group communication server, the SIP invite to request initiation of group communication between a plurality of communication terminal devices; modify the SIP invite; and transmit, via a device-to-device interface, the modified SIP invite to another communication terminal device of the plurality of communication terminal devices, wherein the instructions, when executed, further cause the communication terminal device to set a first on-hold status of the other communication terminal device to off hold at the communication terminal device and to transmit a message, via the first circuitry, to the group communication server to set a second on-hold status of the other communication terminal device to on-hold at the group communication server. - View Dependent Claims (11, 12, 13, 14)
