Abstract

A method for routing media calls over a real time packet switch connection includes providing a session controller for connecting to a network. The method further includes providing a signaling switch for connecting to the session controller. The method further includes controlling call routing in the network with the session controller where the call routing control includes identifiers for elements in at least two layers of a seven layer model. The call routing control includes a preference for a codec for the call. The call routing is carried out taking into consideration a mean opinion score qualifier from previous calls having a same source and destination.

Claims

1. A method for routing of media calls over a real time packet switched connection, comprising the steps of:

providing a session controller for connecting to a network,

providing a signaling switch for connecting to said session controller;

and

controlling call routing of a call in the network with said session controller, wherein the call originates from a user endpoint, said call routing control including identifiers for elements in at least two layers of a seven layer model, wherein the identifiers include a virtual local area network (VLAN) identifier, said call routing control including a preference for a codec for the call, and said call routing being carried out taking into consideration a mean opinion score qualifier from previous calls having a same source and destination as the call, wherein said session controller uses the VLAN identifier to identify the source of the call and after determining the source, the session controller determines said call routing control based on a policy associated with the source that takes into consideration an operator'"'"'s cost of routing, the codec for the call, and the mean opinion score qualifier from previous calls having the same source and destination as the call.

2. A method for routing of media calls as claimed in claim 1, wherein said call routing control includes identifiers for components in layers two and three of the seven layer model.

3. A system for routing of media calls over a real time packet switched connection, the system comprising:

a session controller for connecting to a network;

a signaling switch for connecting to said session controller; and

said session controller for controlling call routing of a call in the network, wherein the call originates from a user endpoint, said call routing control including identifiers for elements in at least two layers of a seven layer model, wherein the identifiers include a virtual local area network (VLAN) identifier, said call control including a preference for a codec for the call, and said call routing being carried out taking into consideration a mean opinion score qualifier from previous calls having a same source and destination as the call, wherein said session controller uses the VLAN identifier to identify the source of the call and after determining the source, the session controller determines said call routing control based on a policy associated with the source that takes into consideration an operator'"'"'s cost of routing, the codec for the call, and the mean opinion score qualifier from previous calls having the same source and destination as the call, wherein the session controller and the signaling switch are implemented using at least one physical component.

4. The system of claim 3 wherein said call routing control includes identifiers for components in layers two and three of the seven layer model.
