Abstract
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.
Claims23
A method for providing high performance dispatch services over a wireless communication network, comprising the steps of:
- receiving a first message at a server from a wireless device indicating the first wireless device is ready to transmit a user communication data to the server, the first wireless device having at least a paging state in which the first wireless device is capable of communicating with the server and a transmission state in which the first wireless device is capable of transmitting the user communication data to the server through a first access channel, the first wireless device being in the paging state when the first message is received by the server;
- transmitting a second message from the server to the first wireless device, the second message instructing the first wireless device to transition from the paging state to the transmission state;
- receiving a third message from the first wireless device at the server indicating the first wireless device is ready to transmit the user communication data to the server through the first access channel;
- and
- receiving the user communication data from the first wireless device.
An apparatus for efficiently transmitting data packets in push-to-talk (PTT) communications to a remote server on a wireless telecommunication network, comprising:
- a transceiver for transmitting data packets to the remote server, the data packets being part of a PTT communication;
- a user interface unit for receiving the PTT communication from a user;
- and
- a controller for maintaining an internal state for the apparatus, the apparatus having at least a paging state in which the wireless device is active and not transmitting the data packets to the remote server and a transmission state in which the wireless is capable of transmitting the user communication data to the server through a first access channel,
- wherein the transceiver transmits a first message to the remote server when the apparatus is the paging state and ready to transmit the data packets, the apparatus transitions from the paging state to the transmission state after receiving a second message from the remote server, and the apparatus transitions from the transmission state to the paging state after the transceiver transmits the data packets on the first access channel to the remote server.
An apparatus for efficiently transmitting data packets in push-to-talk (PTT) communications to a remote server on a wireless telecommunication network, comprising:
- means for transmitting data packets to the remote server, the data packets being part of a PTT communication;
- means for receiving the PTT communication from a user;
- and
- means for maintaining an internal state for the apparatus, the apparatus having at least a paging state in which the wireless device is active and not transmitting the data packets to the remote server and a transmission state in which the wireless is capable of transmitting the user communication data to the server through a first access channel,
- wherein the means for transmitting transmits a first message to the remote server when the apparatus is the paging state and ready to transmit the data packets, the apparatus transitions from the paging state to the transmission state after receiving a second message from the remote server, and the apparatus transitions from the transmission state to the paging state after the means for transmitting transmits the data packets on the first access channel to the remote server.
A computer-readable medium on which is stored a computer program for providing high performance dispatch services over a wireless communication network, the computer program comprising computer instructions that when executed by a computer performs the steps of:
- receiving a first message at a server from a wireless device indicating the first wireless device is ready to transmit a user communication data to the server, the first wireless device having at least a paging state in which the first wireless device is capable of communicating with the server and a transmission state in which the first wireless device is capable of transmitting the user communication data to the server through a first access channel, the first wireless device being in the paging state when the first message is received by the server;
- transmitting a second message from the server to the first wireless device, the second message instructing the first wireless device to transition from the paging state to the transmission state;
- receiving a third message from the first wireless device at the server indicating the first wireless device is ready to transmit the user communication data to the server through the first access channel;
- and
- receiving the user communication data from the first wireless device.
A system for providing high performance dispatch services over a wireless communication network, comprising:
- a server in communication with the wireless communication network, the server selectively transmitting to a user device a plurality of messages;
- a user device capable of communicating with the server through the wireless communications network, the user device having at least a paging state in which the user device is capable of communicating with the server and a transmission state in which the user device is capable of transmitting the user communication data to the server through a first access channel, the user device being capable of:
- transmitting in the paging state a first message to the server informing the server it is ready to transmit a user communication to the server,
- receiving a second message from the server and transitioning to a transmission state, and
- transmitting the user communication to the server through a first access channel the user communication to the server.
A method for providing high performance dispatch services over a wireless communication network, comprising:
- a step for receiving a first message at a server from a wireless device indicating the first wireless device is ready to transmit a user communication data to the server, the first wireless device having at least a paging state in which the first wireless device is capable of communicating with the server and a transmission state in which the first wireless device is capable of transmitting the user communication data to the server through a first access channel, the first wireless device being in the paging state when the first message is received by the server;
- a step for transmitting a second message from the server to the first wireless device, the second message instructing the first wireless device to transition from the paging state to the transmission state;
- a step for receiving a third message from the first wireless device at the server indicating the first wireless device is ready to transmit the user communication data to the server through the first access channel;
- and
- a step for receiving the user communication data from the first wireless device.
