3.1 Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].

HNB, Home Node B, 3G Home Node B: as defined in TS 22.220 [11]. These terms, their derivations and abbreviations are used synonymously throughout this document.

CSG HNB: A HNB that serves a CSG Cell, broadcasting a CSG Indicator and a specific CSG identity.

Non CSG HNB: A HNB that serves a cell which neither broadcasts a CSG Indicator nor a CSG Identity.

Hybrid HNB: A HNB that serves a hybrid cell not broadcasting a CSG Indicator but broadcasting a CSG identity.

Membership Verification: The process that checks whether a UE is a member or non-member of a hybrid cell.

Access Control: The process that checks whether a UE is allowed to access and to be granted services in a closed cell.

CSG ID Validation: The process that checks whether the CSG ID sent via relocation messages is the same as the one supported by the target RAN.

RNSAP Relocation: denotes enhanced mobility for inter-HNB Relocation via RNSAP. In this version of the specification, RNSAP Relocation is only defined for intra-PLMN intra-HNB-GW intra-CSG scenarios.

PLMN ID Check: The process that checks whether a PLMN ID is the RPLMN identity or an EPLMN identity of the UE.

3.2 Abbreviations

For the purposes of the present document, the abbreviations given in TR 21.905 [1] and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905 [1].
