SYSTEM AND METHOD FOR EFFICIENTLY PROVIDING HIGH-PERFORMANCE DISPATCH SERVICES IN A WIRELESS SYSTEM |
摘要 |
A system and method for providing high performance dispatch services for a push-to-talk (PTT) communication over a wireless communication network. When a wireless device is powered up, it registers with a server and then transitions to a paging state instead of an idle state. When the wireless device is ready to transmit PTT communications, it sends a message to the server and transitions to a transmission state when a confirmation is received from the server. Once in the transmission state, the wireless device is ready to transmit the PTT communications to the server. |
