POLICY-DRIVEN LOCAL OFFLOAD OF SELECTED USER DATA TRAFFIC AT A MOBILE EDGE COMPUTING PLATFORM

摘要

The method for optimizing communication for a user identified by a user identifier accessing a service in a telecommunication network, said telecommunication network including a base station, a core network, a IP network external to said core network and an edge site external to said core network and associated to the base station, the edge site including an edge server offering services, the method including the steps of: a. Analyzing at the edge site all traffic packets originating from the user which connects to the network; b. Checking whether the traffic packet requests a service; c. Checking whether the service is available at the server of the edge site; d. rerouting the traffic packet to the edge site on the basis of a forwarding policy which is based either on the user identifier or on information contained in the IP packet portion; e. forwarding the traffic packet to the core network if the traffic packet does not satisfy the policy or the service is not available at the edge site; f. wherein the step of rerouting the traffic packet to the edge site includes rerouting the traffic packet by the serving gateway.
