Abstract

See full text

According to certain embodiments, a network node is operable to change a general packet radio service (GPRS) tunneling protocol (GTP) tunneling endpoint identifier (TEID) when a user equipment (UE) resumes a connection to a core network. The network node comprises processing circuitry operable to receive a resume request from a UE; determine that the UE was previously connected to the network node prior to the resume; obtain one or more GTP TEIDs that are different than GTP TEIDs that were used when the UE was previously connected to the network node; and transmit an indication of the one or more GTP TEIDs to the core network. Transmitting the indication to the core network may comprise a path switch procedure, a UE context resume procedure, or a radio access bearer modification procedure.
