METHOD AND APPARATUS FOR ESTABLISHING AND USING PDN CONNECTIONS

摘要

A method and apparatus for establishing and controlling a tunnel for carrying a PDN connection between a first endpoint and a second endpoint. The first endpoint sends a request to set up a tunnel, the request including a first identifier. It then receives a second identifier for use identifying the tunnel when receiving data sent from the second endpoint to the first endpoint. Data packets are sent from the first endpoint, the data packets including the first and/or second identifiers for identifying the tunnel from the first endpoint to the second endpoint. Data packets are received from the second endpoint, the data packets including the second identifier from the second endpoint to the first endpoint.
