GTP Session Establishment in Edge Computing Networks

The patent implements a universal GTP message transfer and control module that can be deployed in existing core network devices (MME, SGW, PGW) to provide MEC services. This module handles GTP message interception, IP address rewriting, and forwarding to edge servers, allowing existing network infrastructure to serve multiple purposes (traditional core network functions plus MEC support) without requiring dedicated devices at each base station.

The patent introduces a GTP message transfer and control module as an intermediary component within existing core network devices. This module acts as a mediator between the traditional core network and MEC edge servers, intercepting GTP messages, rewriting IP addresses, and routing traffic appropriately. This intermediary approach enables MEC functionality without requiring direct integration at base stations or deploying dedicated MEC devices.

The patent implements preliminary binding of edge servers to tracking areas before handover occurs. When a mobile terminal attaches to the network, the system pre-establishes the relationship between the terminal's tracking area and appropriate edge servers. This preliminary configuration enables seamless handover, as the target edge server is already identified and prepared, eliminating service disruption during mobility events.

The patent implements a feedback mechanism where the GTP message transfer and control module monitors mobile terminal movements and triggers appropriate handover procedures. When a terminal moves to a new tracking area, the system receives feedback about the location change and automatically initiates handover to the appropriate edge server, maintaining continuous service without user-perceived disruption.
