Patent ID: 8804716

Claim:
A method for initiating evolved general packet radio service (GPRS) tunneling protocol (eGTP) indirect tunneling, the method comprising: at a long term evolution (LTE) node simulator including a module for processing data packets: receiving, from a device under test, an eGTP encapsulated data packet associated with a user device, the data packet including an eGTP header having an endpoint identifier for identifying a first transceiver simulated by the LTE node simulator; determining, using the endpoint identifier, whether the data packet is associated with a real or simulated user device that is no longer attached to the first transceiver, wherein determining that the data packet is associated with a real or simulated user device that is no longer attached to the first transceiver includes querying, using the endpoint identifier, a data structure containing endpoint identifiers that are associated with user devices that recently performed mobility events and receiving an indication that the endpoint identifier matches an entry in the data structure; and in response to determining that the data packet is associated with a real or simulated user device that is no longer attached to the first transceiver, sending at least a portion of the data packet to the device under test using an eGTP tunnel.
