Case of CSG UEs:

If the CN has signalled CSG membership update to the HNB:

– If the UE is served by a CSG cell, and is no longer a member of the CSG cell, the HNB may initiate a handover to another cell. If the UE is not handed over, or handover is not initiated, the HNB should request the release of Iu connection (s) with an appropriate cause. The CN initiates Iu release after a configurable time, if the UE is not handed over or released by the CSG cell (TS 23.060 [10]).

– If the UE is served by a Hybrid cell, the HNB may use the new membership information to perform differentiated treatment for member and non-member UEs.

Case of non-CSG UEs:

If the HNB-GW has signalled CSG membership update to the HNB:

– If the UE is served by a CSG cell, and is no longer a member of the CSG cell, the HNB may initiate a handover to another cell. If the UE is not handed over, or handover is not initiated, the HNB should request the release of Iu connection (s) with an appropriate cause. The HNB-GW shall initiate UE De-Registration after a configurable time, if the UE is not handed over or released by the serving HNB.

– If the UE is served by a Hybrid cell, the HNB may use the new membership information to perform differentiated treatment for member and non-member UEs.
