Usage Guidelines
If no optional keywords are included with the release-access-bearer command, then the S4-SGSN applies
Release Access Bearer for both 2G and 3G networks.
Release Access Bearer for both 2G and 3G networks.
By default, Release Access Bearer initiation on Iu-Release or Ready-to-Standby transition is not enabled.
When disabled or prior to being enabled, either/both remove release-access-bearer on-iu-release or/and remove
release-access-bearer on-ready-to-standby will display in the output generated by the show configuration [
verbose ] command.

This command, in compliance with 3GPP TS 23.060 v11.7.0, provides the operator with the option to have
the S4-SGSN send Release Access Bearer Request to the S-GW to remove the downlink user plane on the
S4 interface for non-DT and non-ISR scenarios.
the S4-SGSN send Release Access Bearer Request to the S-GW to remove the downlink user plane on the
S4 interface for non-DT and non-ISR scenarios.
In accordance with 3GPP TS 23.401 v11.8.0, if the SGSN and the S-GW are configured to release S4 U-Plane
when the EPS bearer contexts associated with the released RABs are to be preserved, then the SGSN should
not send SGSN address and TEID for U-Plane in the Modify Bearer Request (MBR). The operator can now
use the rau-inter exclude-uteid-in-mbr command (under Call-Control Profile configuration mode) to configure
the SGSN not to send the UTEID in the MBR.

Examples
To enable release access bearer in both 2G and 3G networks, use a command similar to the following:
release-access-bearer
release-access-bearer
To disable release access bearer in 3G networks, use a command similar to the following:
remove release-access-bearer on-iu-release
remove release-access-bearer on-iu-release
