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.

Claims

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.

2. The communication terminal device of claim 1, wherein the SIP invite is a first SIP invite, which is directed to the other communication terminal device and the receiver is to receive a second SIP invite, which is directed to the communication terminal device to request that the communication terminal device be included in the group communication.

3. The communication terminal device of claim 1, wherein the message is a SIP update message.

4. The communication terminal device of claim 1, wherein the first circuitry is to receive data via a real-time transport protocol (RTP) or a real-time transport control protocol (RTCP), the controller is to present a representation of the received data to a user of the communication terminal device and is further to forward the received data to the other communication terminal device via the second circuitry.

5. The communication terminal device of claim 4, wherein the data, as received by the first circuitry, is directed to the communication terminal device, but not the other communication terminal device.

6. The communication terminal device of claim 1, wherein the controller is to generate data of the group communication and transmit the data via the first circuitry and the second circuitry.

7. The communication terminal device of claim 1, wherein the controller includes a back-to-back user agent.

8. The communication terminal device of claim 1, wherein the group communication server is a proximity services server.

9. The communication terminal device of claim 1, wherein the second circuitry is wireless local area network (WLAN) circuitry.

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.

11. The one or more non-transitory, computer-readable media of claim 10, wherein the SIP invite is a first SIP invite, which is directed to the other communication terminal device and the instructions, when executed, further cause the communication terminal device to process a second SIP invite, which is directed to the communication terminal device to request that the communication terminal device be included in the group communication.

12. The one or more non-transitory, computer-readable media of claim 10, wherein the instructions, when executed, further cause the communication terminal device to process data, received via a real-time transport protocol (RTP) or a real-time transport control protocol (RTCP), to present a representation of the received data to a user of the communication terminal device, and to forward the received data to the other communication terminal device via the second circuitry.

13. The one or more non-transitory, computer-readable media of claim 12, wherein the data, as received by the communication terminal device, is directed to the communication terminal device, but not the other communication terminal device.

14. The one or more non-transitory, computer-readable media of claim 10, wherein the instructions, when executed, further cause the communication terminal device to generate data of the group communication and transmit the data via the first circuitry and the second circuitry.
