  • Redirecting Data Flow Of A Secondary PDP To A Primary PDP Before Establishing The Secondary PDP Context
    Publication number: 20090052419
    Abstract: A solution in a telecommunications infrastructure network for creating a secondary PDP context for a time critical application, ensuring that no packets are lost by masquerading a primary PDP context as the secondary PDP context. This may be achieved by for instance sending a fake TEID or including a filter in a PDP creation request for the secondary PDP context and updating the GGSN with a correct TEID or a new Traffic Flow Template (TFT) when the secondary PDP context is established.
