39、re 4.1-1: Interaction between RNC and O&M due to ANR The ANR function resides in the RNC and is composed of the Neighbour Relation Table (NRT) Management Function, Neighbour Detection Function and Neighbour Removal Function. The Neighbour Detection Function detects new neighbours and adds them to th
40、e NRT. The Neighbour Removal Function removes outdated NRs. ETSI ETSI TS 125 484 V15.0.0 (2018-07)73GPP TS 25.484 version 15.0.0 Release 15A Neighbour cell Relation (NR) between a Base UTRAN Cell and a Neighbour Cell exists if the RNC controlling the Base UTRAN Cell: a) Knows the following Neighbour
41、 Cell information: - Neighbour cell is in UTRAN: PLMN-Id, Cell Identifier(C-ID), RNC-ID/Extended RNC-ID, - Neighbour cell is in LTE: ECGI (PLMN Id + Cell Identity) - Neighbour cell is in GSM/GERAN: PLMN Id, LAC, CI, BSIC b) Has an entry in the Neighbour Relation Table for the Base UTRAN Cell identif
42、ying the neighbour cell. c) Has all required attributes defined in the Neighbour Relation Table entry or set to default values. Among these attributes are the frequency information (UARFCN, BCCH ARFCN, EARFCN) and handover routing parameters not already considered in (a): - Neighbour cell is in UTRA
43、N: LAC and RAC - Neighbour cell is in LTE: TAI For each NR, the NRT contains the Neighbour Cell Identifier (NCI), which identifies the neighbour cells. A neighbour cell may be a UTRAN, LTE or GSM cell. Furthermore, each NR has two attributes, the No Remove and the No HO attributes. These attributes
44、have the following definitions: - No Remove: If checked, the RNC shall not remove the Neighbour cell Relation from the NRT. - No HO: If checked, the Neighbour cell Relation shall not be used as a neighbour cell by Intra RNS, Inter RNS or Inter RAT mobility functions in UTRAN. The ANR function also a
45、llows O&M to manage the NRT. O&M can add and delete NRs. It can also change the attributes of the NR. The O&M system is informed about changes in the NRT. 4.2 ANR Handling in the UTRAN Infrastructure - Overall Description If UTRAN ANR functionality is supported in UTRAN, RNC shall be able to configu
46、re the UE to perform the ANR measurement. ANR capable UE performs the ANR measurement and records in its logbook newly detected cells which meet the criteria given in the configuration. The Receiving RNC uses RRC signalling to retrieve the ANR report over the Uu interface after the UE has indicated
47、that it has a logged ANR report. The Receiving RNC handles the ANR report and may forward the ANR report to different RNCs. This chapter illustrates the handling and message sequences to be used to configure a new neighbour relation for a UTRAN cell. 4.2.1 Iur Connectivity exists between the involve
48、d RNCs The ANR function supports forwarding of ANR reports from the Receiving RNC to RNCs indicated as Base RNCs in the ANR report. Furthermore the ANR function supports suspension (and resuming) ANR logs reporting over Iur from other RNCs as described in 5.1.2. This chapter describes the handling i
49、n the Receiving, Base and Neighbour RNCs when Iur connectivity exists between the involved RNCs. 4.2.1.1 ANR Report over Uu for UTRAN cells When receiving an ANR report over Uu, the Receiving RNC uses the globally unique cell identities in the report to determine the network addresses of the RNCs that are controlling the Base UTRAN cells. The network address of this Base RNC is retrieved using configuration in the Receiving RNC and/or O&M. The Receiving RNC decides the necessity to forward the ANR report. If the Base UTRAN Cell is under control of the Receiving RNC, t
