1  Scopep. 5

The present document is a technical specification of the overall support of Automatic Neighbour Relation (ANR) Function in UTRA.

2  Referencesp. 5

The following documents 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 a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

3  Definitions, symbols and abbreviationsp. 5

3.1  Definitionsp. 5

For the purposes of the present document, the terms and definitions given in TR 21.905 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.
Base UTRAN Cell:
A cell in UTRAN for which a missing neighbour cell is detected.
Neighbour Cell:
A cell in UTRAN, LTE or GSM/GERAN that is a neighbour cell to a Base UTRAN Cell.
Neighbour Cell Identifier (NCI):
The identifier of a Neighbour Cell
Neighbour cell Relation (NR):
Information that a Neighbour Cell, identified with NCI, is a neighbour to a Base UTRAN Cell. NR is stored in the RNC controlling the Base UTRAN Cell.
Conceptual Neighbour Relation Functions:
The ANR is described using a number of conceptual entities and functions in the RNC: Neighbour Relation Table, Neighbour Relation Table Management Function, Neighbour Removal Function and Neighbour Detection Function. These entities and functions are used for descriptive purpose only and shall not be regarded as requirements on the implementation in RNC.
Receiving RNC:
the RNC receiving the ANR report over Uu
Base RNC:
the CRNC of the Base UTRAN Cell
Neighbour RNC:
the CRNC of the Neighbour Cell in UTRAN
A list of PLMNs that is the RPLMN and the list of equivalent PLMNs for the UE at the point of receiving ANR logging configuration.
ANR measurement:
Physical measurements and reading of System Information towards detected cells outside NCL.
ANR logging:
Storing of essential information of detected cell into UE internal ANR log, when one or more detected cell satisfies ANR logging criteria.

3.2  Symbolsp. 6


3.3  Abbreviationsp. 7

For the purposes of the present document, the abbreviations given in TR 21.905 apply.
