Abstract
A voice/data combination system and a method that manages a bandwidth in the system. A determination is made as to whether a bandwidth for real-time data service is available, and the bandwidth, when not available, is reserved, so that the real-time data service is performed when the bandwidth is available. The system reserves predetermined bandwidths for real-time packets when bandwidth of real-time packets is not available, and process the real-time packets in their corresponding reserved bandwidth when bandwidth is available. Therefore, real-time packets and general packets are always processed in their corresponding bandwidths.
Claims12
A voice/data combination system, comprising:
- a terminal for generating and transmitting a real-time data service request message upon a receipt of a request for real-time data service, generating and transmitting a bandwidth request message for real-time data service upon a receipt of a message indicating that a bandwidth for real-time data service is unavailable, and then retransmitting the real-time data service request message upon a receipt of a bandwidth reservation message;
- and
- a switch/router for checking a network bandwidth in response to the real-time data service request message, transmitting a message indicating that the bandwidth, when unavailable, is unavailable, reserving the bandwidth in response to the bandwidth request message received from the terminal, and then transmitting the bandwidth reservation message to the terminal when the bandwidth is available.
A voice/data combination system, comprising:
- a VoIP (voice over IP) terminal for generating and transmitting a VoIP call request message upon receipt of a request for a VoIP call, generating and transmitting a bandwidth request message for VoIP call upon receipt of a message indicating the bandwidth for VoIP call unavailable, and then retransmitting the VoIP call request message upon receipt of a bandwidth reservation message;
- and
- a switch/router for checking a network bandwidth in response to the VoIP call request message, transmitting a message indicating that the bandwidth, when unavailable, is unavailable, reserving the bandwidth in response to the bandwidth request message received from the VoIP terminal, and then transmitting the bandwidth reservation message to the VoIP terminal when the bandwidth is available.
A method for managing a bandwidth in a voice/data combination system, comprising the steps of:
- generating and transmitting, by a terminal, a real-time data service request message upon receipt of a request for real-time data service;
- checking, by a switch/router, a network bandwidth in response to the real-time data service request message and transmitting a message indicating that the bandwidth, when unavailable, is unavailable;
- generating and transmitting, by the terminal, a bandwidth request message for real-time data service in response to the message indicating that the bandwidth is unavailable;
- and
- reserving, by the switch/router, the bandwidth in response to the bandwidth request message received from the terminal, and then transmitting a bandwidth reservation message to the terminal when the bandwidth is available.

A method for managing a bandwidth in a voice/data combination system, comprising the steps of:
- generating and transmitting, by a VoIP (voice over IP) terminal, a VoIP call request message in response to a VoIP call request from a correspondent terminal;
- checking, by a switch/router, a network bandwidth in response to the VoIP call request message and transmitting a message indicating that the bandwidth, when unavailable, is unavailable, to the VoIP terminal;
- generating and transmitting, by the VoIP terminal, a bandwidth request message for a VoIP call in response to the message indicating that the bandwidth is unavailable;
- transmitting the VoIP invite message to the correspondent terminal in response to the message indicating that the bandwidth is available;
- and
- reserving, by the switch/router, the bandwidth in response to the bandwidth request message received from the VoIP terminal, and then transmitting a bandwidth reservation message to the terminal when the bandwidth is available.

A voice/data combination system, comprising:
- a VoIP (voice over IP) terminal for generating and transmitting a VoIP invite message upon receipt of a request for a VoIP call from a correspondent terminal, generating and transmitting a bandwidth request message for a VoIP call upon receipt of a message indicating the bandwidth for VoIP call unavailable, and then re-transmitting the VoIP call request message upon receipt of a bandwidth reservation message;
- a switch/router comprising a VoIP ALG (Application Layer Gateway) processor and a traffic manager;
- said traffic manager determining the availability of a network bandwidth in response to the VoIP invite message, and generating a bandwidth check response message indicating the availability of the bandwidth;
- said VoIP ALG processor transmitting the VoIP invite message to the correspondent terminal when said bandwidth check response message indicates that the bandwidth is available, and said VoIP ALG processor generating a message indicating that the bandwidth, when said bandwidth check response message indicates that the bandwidth is unavailable, is unavailable;
- and
- said VoIP ALG reserving the bandwidth in response to the bandwidth request message received from the VoIP terminal, and then transmitting the bandwidth reservation message to the VoIP terminal when the bandwidth is available.
