24、-07)53GPP TS 25.367 version 15.0.0 Release 151 Scope This document provides a high level description of the mobility procedures applicable to Home NodeB support in the current Release. Where appropriate, the reasons behind the agreements are provided. Throughout this document, unless otherwise state
25、d, the UE is assumed to be a current Release UE that supports the Closed Subscriber Group (CSG) feature, whether it is actually a member of a CSG or not. A UE that does not support the CSG feature is not required to support any of the procedures stated in this document. 2 References The following do
26、cuments contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For
27、a non-specific reference, the latest version applies.

Acceptable Cell: A cell that satisfi
30、es certain conditions as specified 2. A UE can always attempt emergency calls on an acceptable cell. CSG whitelist: A list provided by NAS containing all the CSG Identities of the CSGs to which the subscriber belongs. NOTE: This list is known as Allowed CSG List in Rel-8 Access Stratum specification
31、s. Available PLMN: A PLMN for which the UE has found at least one cell and read its PLMN identity. Barred Cell: A cell a UE is not allowed to camp on. Camped on a cell: UE has completed the cell selection/reselection process and has chosen a cell. The UE monitors system information and (in most case
32、s) paging information. Camped on any cell: UE is in idle mode and has completed the cell selection/reselection process and has chosen a cell irrespective of PLMN identity. Closed Subscriber Group (CSG): A Closed Subscriber Group identifies subscribers of an operator who are permitted to access one o
33、r more cells of the PLMN but which have restricted access (CSG cells). ETSI ETSI TS 125 367 V15.0.0 (2018-07)63GPP TS 25.367 version 15.0.0 Release 15CSG Cell: A cell, part of the PLMN, broadcasting a CSG Indicator that is set to TRUE and a specific CSG identity. A CSG cell is accessible by the memb
34、ers of the closed subscriber group for that CSG identity. CSG Identity (CSG ID): An identifier broadcast by a CSG/Hybrid cell or cells and used by the UE to facilitate access for authorised members of the associated Closed Subscriber Group. CSG member cell: A cell broadcasting the identity of the se
35、lected PLMN, registered PLMN or equivalent PLMN and for which the CSG whitelist of the UE includes an entry comprising cells CSG ID and the respective PLMN identity. DRX cycle: Individual time interval between monitoring Paging Occasion for a specific UE. Equivalent PLMN list: List of PLMNs consider
36、ed as equivalent by the UE for cell selection, cell reselection , MBSFN Cluster selection MBSFN Cluster reselection and handover according to the information provided by the NAS. Home NodeB (HNB): A HNB is a customer-premises equipment that connects a 3GPP UE over UTRAN wireless air interface to a m
37、obile operators network using broadband IP backhaul. HNB Name: The Home NodeB Name is a broadcast string in free text format that provides a human readable name for the Home NodeB CSG identity. Home PLMN: A PLMN where the Mobile Country Code (MCC) and Mobile Network Code (MNC) of the PLMN identity a
38、re the same as the MCC and MNC of the IMSI. Hybrid cell: A cell broadcasting a CSG identity which is accessible as a CSG cell by UEs which are members of the CSG and as a normal cell by all other UEs. Non-CSG Cell: A cell that is not a CSG cell, e.g. a macro cell. Process: A local action in the UE i
39、nvoked by a RRC procedure or an Idle Mode procedure. Radio Access Mode: Radio access mode of the cell, FDD or TDD. Radio Access Technology: Type of technology used for radio access, for instance UTRA or GSM. Registered PLMN: This is the PLMN on which certain Location Registration outcomes have occur
40、red. Registration Area: (NAS) registration area is an area in which the UE may roam without a need to perform location registration, which is a NAS procedure. Reserved Cell: A cell on which camping is not allowed, except for particular UEs, if so indicated in the system information. Restricted Cell:
41、 A cell on which camping is allowed, but access attempts are disallowed for UEs whose access classes are indicated as barred. Selected PLMN: This is the PLMN that has been selected by the NAS, either manually or automatically. Serving cell: The cell on which the UE is camped. Strongest cell: The cel
42、l on a particular carrier that is considered strongest according to the layer 1 cell search procedure 7. As the details of the layer 1 cell search are implementation dependent, the precise definition of strongest cell is also implementation dependent. Suitable Cell: This is a cell on which an UE may
43、 camp. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TR 21.905 1 and the following apply.

47、Access Network 4 Overview A Home NodeB may provide restricted access to only UEs belonging to a Closed Subscriber Group (CSG). One or more of such cells providing restricted access, known as CSG cells, are identified by a unique numeric identifier called CSG Identity. To facilitate access control, a
48、 UE with CSG subscription would have an CSG whitelist, which contains one or more CSG Identities associated with the CSG cells on which the UE is allowed access. The UE uses the CSG whitelist along with the CSG Identity and associated PLMN ID broadcast by the CSG Cells in CSG cell selection and rese
49、lection. A HNB can also be operated as a hybrid cell. A hybrid cell is accessed as a CSG cell by a UE whose CSG whitelist contains the cells CSG ID and associated PLMN ID and as a normal cell by all other UEs. Members of the CSG are expected to receive preferential access according to 5. NOTE: Although pre-Rel-9 UEs are able to camp on hybrid cells (which would be regarded as normal cells for access) there is no possibility for these UEs to identify a hybrid cell as a CSG cell even though the cells CSG identity and associated PLMN ID are in
