  • Method and device for controlling access to a channel in a conventional multi-site communication system
    Patent number: 8078209
    Abstract: A repeater receives and repeats, on a multi-site channel, a sequence of control and media transmissions included in a session, wherein the session has a plurality of participants. While repeating these transmissions, the repeater further detects, from at least one of the transmissions, a start of the session and a type of the session. Based on the type of the session, the repeater determines whether to perform an arbitration during the session to control access to the multi-site channel, and restricts each performed arbitration to only transmissions received from the participants to the session. In addition, after repeating at least one of the control transmissions, the repeater sets a hang time having a duration that is determined based on a type of the transmission preceding the setting of the hang time.
