/* From GPP TS 23.401 version 11.11.0 Release 11, section 5.3.5 S1 release procedure:
* The S-GW releases all eNodeB related information (address and TEIDs) for the UE and responds with a Release
* Access Bearers Response message to the MME. Other elements of the UE's S-GW context are not affected. The
* S-GW retains the S1-U configuration that the S-GW allocated for the UE's bearers. The S-GW starts buffering
* downlink packets received for the UE and initiating the "Network Triggered Service Request" procedure,
* described in clause 5.3.4.3, if downlink packets arrive for the UE.
