发明名称 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.
