Abstract
An apparatus and method for processing a call in a PTT system where, when an outgoing terminal transmits an invitation message for PTT service or for call setup to a predetermined incoming terminal in a dormant state, the outgoing terminal transmits the invitation message together with address information on the incoming terminal to enable a PTT server to detect the location of the incoming terminal before the invitation message is transmitted to the incoming terminal, thereby reducing the time taken to set up a PTT call.
Claims26
An apparatus for processing a call in a PTT (Push-To-Talk) system, the apparatus comprising:
- a receiving unit;
- and
- a PTT server;
- wherein
- the receiving unit
- receives an invitation request message from an outgoing terminal to provide a PTT service to an incoming terminal, the invitation request message comprising address information on the incoming terminal,
- provides the received invitation request message to the PTT server,
- detects a location of the incoming terminal using the address information on the incoming terminal, and
- provides an invitation message generated from the PTT server to the incoming terminal;
- and
- the PTT server
- receives the invitation request message from the unit,
- performs an internal resource assignment for performing a call connection between the outgoing terminal and the incoming terminal, and
- generates the invitation message for inviting the incoming terminal to the PTT service after completing the internal resource assignment.
An apparatus for processing a call in a PTT (Push-To-Talk) system, the apparatus comprising:
- a PTT server;
- a message generator for receiving an invitation request message from an outgoing terminal to provide a PTT service to an incoming terminal, and for generating a location detection message to detect the location of the incoming terminal, the location detection message comprising address information on the incoming terminal;
- and
- a provider for detecting the location of the incoming terminal according to the location detection message, using the address information on the incoming terminal, and for providing an invitation message generated from the PTT server to the incoming terminal whose location is detected;
- wherein the PTT server
- receives the invitation request message,
- performs an internal resource assignment for performing a call connection between the outgoing terminal and the incoming terminal, and
- generates an invitation message after completing the internal resource assignment.
An apparatus for processing a call in a PTT (Push-To-Talk) system, the apparatus comprising:
- a PTT server for receiving an invitation request message from an outgoing terminal to provide a PTT service to an incoming terminal, for performing an internal resource assignment for a call connection between the outgoing terminal and the incoming terminal, for generating a terminal location request message comprising address information on the incoming terminal to detect the location of the incoming terminal, and for, upon detection of a base station system where the incoming terminal is located, generating an invitation message for inviting the incoming terminal to the PTT service;
- and
- a receiving unit for detecting the base station system where the incoming terminal is located, using the address information on the incoming terminal, and for transmitting the invitation message to the detected base station system where the incoming terminal is located.
A method for processing a call in a PTT (Push-To-Talk) system, the method comprising the steps of:
- receiving an invitation request message from an outgoing terminal to provide a PTT service to a incoming terminal, the invitation request comprising address information on the incoming terminal;
- detecting a location of the incoming terminal using the address information on the incoming terminal;
- and
- performing an internal resource assignment for a call connection between the outgoing terminal and the incoming terminal;
- after completing the internal resource assignment, generating an invitation message for inviting the incoming terminal to the PTT service;
- and
- transmitting the generated invitation message to the incoming terminal.
A method for processing a call in a PTT (Push-To-Talk) system, the method comprising the steps of:
- receiving an invitation request message from an outgoing terminal to provide a PTT service to an incoming terminal;
- providing the received invitation request message to a PTT server;
- receiving a location detection request message for detecting the location of the incoming terminal from the PTT server, the location detection request comprising address information on the incoming terminal;
- detecting a location of the incoming terminal using the address information on the incoming terminal;
- completing an internal resource assignment for a call connection between the outgoing terminal and the incoming terminal;
- receiving an invitation message for inviting the incoming terminal to the PTT service from the PTT server;
- and
- transmitting the invitation message to the incoming terminal.
