Abstract
A technique for transmitting and using a session identifier of a session between a user plane gateway and a control plane gateway is disclosed. In a method implementation, a third gateway, GW, in a Control Plane, CP, of an Evolved Packet Core, EPC, transmits, to a fourth GW in the CP, a session identifier of a first session established between a second GW in a User Plane, UP, of the EPC and the third GW, wherein the second GW is co-located with a first GW in the UP and wherein the first GW has a communication interface to the fourth GW. The fourth GW may receive the session identifier from the third GW and provide the session identifier to the first GW. The first GW may receive a data packet, forward the data packet to the second GW and provide, to the second GW, the session identifier. The second GW may receive the data packet from the first GW and obtain the session identifier from the first GW.
