METHOD AND SYSTEM FOR DIRECT MODE COMMUNICATION WITHIN A TALKGROUP |
摘要 |
A method and system for direct mode operation (DMO) of a talkgroup enables device to device (D2D) DMO operation leveraged from a Land Mobile Radio (LMR) system. The method includes scanning at a radio receiver a defined radio frequency spectrum; receiving at the radio receiver in the defined radio frequency spectrum a wake-up signal; identifying a talkgroup identifier in the wake-up signal, wherein the talkgroup identifier corresponds to a talkgroup being monitored by the radio receiver; in response to identifying the talkgroup identifier, decoding code sequences included in the wake-up signal; identifying in at least one of the code sequences both a center frequency and a transmission bandwidth of the DMO transmission; and tuning the radio receiver to receive the DMO transmission at the center frequency and transmission bandwidth. |
