The present invention relates to a gateway between two networks of a communication system. A plurality of communication service classes is available for the communication between the networks. In the method a call is routed from a network to another network via the gateway. The type of the call is defined. A gateway controller also determines the communication service class that is to be used for the call. The gateway controller communicates information that associates with the determined service class to the gateway. The communication is based on a communication protocol message that has been adapted to transport said information between the gateway controller and the gateway. The call is then processed based on said information
A method in a communication system, comprising:
A method as claimed in any preceding claim, wherein the type of the call is defined to be one of the following:
A method as claimed in any preceding claim, wherein the type of the call is defined based on information from a call type detection function provided in the gateway.
A method as claimed in any of the preceding claims, wherein the service class information is contained in a data element included in the protocol message.
A method as claimed in any preceding claim, wherein at least one of the networks is a packet switched data network.
A method as claimed in any preceding claim, wherein the call comprises a voice call between two terminals, the first terminal being connected to the first network and the second terminal being connected to the second network.
A method as claimed in any preceding claim, wherein the call is classified by a classifier function of the gateway based on the class information received from the gateway controller function.
A method as claimed in any preceding claim, wherein the protocol message is adapted to transport information that associates with the type of service field of the call.
A method as claimed in any preceding claim, wherein the protocol message is adapted to transport information that associates with differentiated services codepoint.
A method as claimed in any preceding claim, wherein the protocol message is adapted to transport information that associates with multi-protocol label switched/asynchronous transfer mode parameter.
A method as claimed in any preceding claim, wherein the service differentiation is based on mapping between multi-protocol label switched tunnels and asynchronous transfer mode channels.
A method as claimed in any preceding claim, wherein the gateway assigns data packets that associate with the call with a class identifier based on said information of the determined service class.
A method as claimed in any preceding claim, wherein the gateway controller determines the service class based on at least one of the following information:
A method as claimed in any preceding claim, wherein the gateway controller provides dynamic control of the classification function of the gateway.
A communication system, wherein a plurality of communication service classes may be used for calls in said system, comprising:
A gateway arrangement for a communication system, comprising:
Dependencies are inferred from the claim text.
