Abstract
Systems, methods and computer software are disclosed for providing network address translation with a tunnel identifier (TEID) in a cellular network. A HetNet Gateway (HNG) allocates at least a portion of a unique TEID for a user equipment (UE). The HNG receives a packet having a source field in the packet header including an Internet Protocol (IP) address. The HNG replaces the IP address in a source field of the packet header of the packet with the unique TEID for the UE and forwards the packet using the unique TEID to a packet gateway (PGW).

A method for providing network address translation with a tunnel identifier (TEID) in a cellular network, comprising:
- allocating, by a HetNet Gateway (HNG), at least a portion of a unique TEID for a user equipment (UE);
- receiving, at the HNG, a packet having a source field in the packet header including an Internet Protocol (IP) address;
- replacing, by the HNG, the IP address in a source field of the packet header of the packet with the unique TEID for the UE;
- and
- forwarding the packet using the unique TEID to a packet gateway (PGW).
A system for providing network address translation with a tunnel identifier (TEID) in a cellular network, comprising:
- a HetNet Gateway (HNG);
- a User Equipment (UE) in wireless communication with the HNG;
- wherein the HNG allocates at least a portion of a unique TEID for a user equipment (UE), wherein the HNG receives a packet having a source field in the packet header including an Internet Protocol (IP) address;
- wherein the HNG replaces the IP address in a source field of the packet header of the packet with the unique TEID for the UE, and forwards the packet using the unique TEID to a packet gateway (PGW).
A non-transitory computer-readable medium containing instructions for providing network address translation with a tunnel identifier (TEID in a cellular network which, when executed, cause a HetNet Gateway (HNG) to perform steps comprising:
- allocating at least a portion of a unique TEID for a user equipment (UE);
- receiving a packet having a source field in the packet header including an Internet Protocol (IP) address;
- replacing the IP address in a source field of the packet header of the packet with the unique TEID for the UE;
- and
- forwarding the packet using the unique TEID to a packet gateway (PGW);
