Patent ID: 6925304

Claim:
A method for data connections in a cellular mobile communication network having at least one core network and at least one access network, said method comprising the steps of: receiving a connection request in a first control node of the core network from a first access network; transferring of a call control from the first control node to a gateway control node interacting with a home location register that manages subscriber data of a called party; fetching of routing information by the gateway control node from said home location register; transferring of the call control from the gateway control node to a control node that controls the access network serving the called party; seizing first payload transmission resources by the first control node; seizing second payload transmission resources by the control node controlling the access network serving the called party; calculating parameter values describing possible payload connections between the core network end the access networks, as defined by the seized first end second payload transmission resources; comparing parameter values describing possible payload connections between the core network and the first access network, with parameter values of possible payload connections between the core network and the access network serving the called party; selecting a transcoding technique and a data rate of the payload in the respective payload transmission resources, according to the results of the comparison; and setting up and through-connecting the selected payload transmission resources.
