Adjusting connection bandwidth in a data network
First Claim
1. A method for adjusting a bandwidth of a connection between at least two communication endpoints in a data network, the method comprising the steps of:
- assigning the connection at least one transmission channel for data transmission, the connection including a signaling connection and a user channel connection;
transmitting user data in packet-oriented form via the user channel connection between the communication endpoints;
allocating the user data to at least one communication connection;
monitoring, via a monitoring unit, the signaling connection for requests for at least one further communication connection;
signaling to a control unit, via the monitoring unit and in the event of a request, to assign to the connection at least one additional free transmission channel for the requested at least one further communication connection;
carrying out a check to determine whether the bandwidth is sufficient for the requested communication connection;
determining whether an appropriately large number of transmission channels are free for the bandwidth requirements for the requested communication connection;
storing the connection request in a queue;
setting up free transmission channels;
deleting the stored connection request; and
assigning the set-up transmission channels to the user channel connection.

Abstract
A method and apparatus are disclosed for adjusting the bandwidth of a connection between at least two communication endpoints in a data network via a monitoring unit and a control unit. The connection in the data network is assigned at least one transmission channel for data transmission. The user data is, in this case, allocated to at least one communication connection; in particular a voice connection. The monitoring unit monitors the signaling connection for requests for at least one further communication connection; in particular, a voice connection. When a request occurs, it signals to the control unit to assign to the connection one or more additional free transmission channels for the at least one requested communication connection.

7. An apparatus for adjusting a bandwidth of a connection between at least two communication endpoints in a data network, comprising:
-
a router having both a monitoring unit and a control unit, with the monitoring unit being connected to the control unit via a signal line, wherein the connection is assigned at least one transmission channel for data transmission, with the connection including a signaling connection and a user channel connection, user voice-over IP data is transmitted in packet-oriented form via the user channel connection between the communication endpoints, the user data is allocated to at least one communication connection, the monitoring unit monitors the signaling connection for requests for at least one further communication connection and, in the event of a request, signals to the control unit to assign to the connection at least one additional free transmission channel for the requested at least one further communication connection,; wherein the monitoring unit carries out a check to determine whether the bandwidth is sufficient for the requested communication connection and determines whether an appropriately large number of transmission channels are free for the bandwidth requirements for the requested communication connection;
andwherein the control unit stores the connection request in a queue;
setting, sets up free transmission channels, and deletes the stored connection request, and assigns the set-up transmission channels to the user channel connection. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus comprising:
a router configured to; set up a first transmission channel configured to transmit packet-based voice data between first and second communication endpoints; assign a first port number to a connection including the first transmission channel; receive a request for a second transmission channel, wherein the second transmission channel is configured to transmit packet-based voice data between the first and second communication endpoints; store the received request in a queue; determine whether sufficient bandwidth is available to service the request while maintaining a current quality of service for other established transmission channels; if the sufficient bandwidth is available, set up the second transmission channel, including assigning a second port number to the second transmission channel, and assign the second transmission channel to the connection including the first transmission channel; and
delete the stored request from the queue.- View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

27. An apparatus comprising:
-
a monitoring unit; and a control unit; wherein the apparatus is configured to; in response to a request for a digital voice communication connection, determine whether sufficient free bandwidth is available to service the request while maintaining a current quality of service for other digital voice communication connections monitored by the apparatus, wherein the request for the digital voice communication connection corresponds to a connection between an origin and a destination; and in response to determining that sufficient free bandwidth is available to service the request, establish one or more free transmission channels and assign the established one or more free transmission channels to the digital voice communication connection, wherein determining that sufficient free bandwidth is available comprises performing a first check on a first connection between the apparatus and the origin and performing a second check on a second connection between the apparatus and the destination; and in response to determining that sufficient free bandwidth is not available, deny the request. - View Dependent Claims (28, 29, 30)
