COMMUNICATION METHOD BETWEEN TERMINALS AND TERMINAL

摘要

The present disclosure relates to technologies for a sensor network, machine-to-machine (M2M) communications, or machine type communications (MTC), and Internet of things (IoT), and may be utilized in intelligent services, based on the above technologies, such as a smart home, a smart building, smart cities, smart cars or connected cars, smart grids, healthcare, smart electronics, advanced medical services, public safety network communications through fusion and convergence with conventional IT technologies and various industries. Data transmission control between a group of uncoordinated electronic devices in a computer network including the use of transmission authorization request messages and transmission authorization grant messages.

主权项

1. A terminal comprising:
a communicator configured to receive media data of a first terminal having a transmission authority among other terminals included in a group including a terminal, transmit a transmission authority request message to each of the other terminals of the group, retransmit the transmission authority request message to the first terminal when the media data of the first terminal is not received for a certain time and transmit the media data of the terminal when the transmission authority request acceptance message is not re-received within a certain time after retransmitting the transmission authority request message; and a controller configured to determine whether the media data of the first terminal is received.
