ETSI ETSI TS 125 484 V14.0.0 (2017-04)83GPP TS 25.484 version 14.0.0 Release 14A 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 Cell information: - Neighbour cell is in UTRAN: PLMN-Id,
35、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 identifying the neighbour cell. c) Has all required attributes de
36、fined 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 UTRAN: LAC and RAC - Neighbour cell is in LTE: TAI For each NR
37、, 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 have the following definitions: - No Remove: If checked, t
38、he 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 allows O&M to manage the NRT. O&M can add and delete NRs. I
39、t 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 configure the UE to perform the ANR measurement. ANR capable UE p
40、erforms 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 that it has a logged ANR report. The Receiving RNC handles
41、 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 involved RNCs The ANR function supports forwarding of ANR reports
42、 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 in the Receiving, Base and Neighbour RNCs when Iur connecti
43、vity 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 addre
44、ss 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, the Receiving RNC terminates the relevant ANR report entry, and may update the Neighb
45、ouring Relation accordingly. Otherwise, the ANR report is forwarded to the Base RNCs over Iur with the RNSAP Direct Information Transfer procedure. ETSI ETSI TS 125 484 V14.0.0 (2017-04)93GPP TS 25.484 version 14.0.0 Release 14If newly detected neighbour cells are controlled by another RNC the RNSAP
46、 Information Exchange Initiation procedure is used to request cell information from the neighbour RNC. In addition the Base RNC may interact with O&M before a neighbour relation is stored in the NRT. Figure 4.2.1.1-1 ANR Report over Uu for UTRAN cells 4.2.1.2 ANR Report over Iur for UTRAN cells On r
47、eception of an ANR report from another RNC using the RNSAP Direct Information Transfer procedure, the Base RNC uses the globally unique cell identities and L1 information in the ANR report, and optionally also configuration in the RNC/O&M, to determine if the ANR report contains any potential neighb
48、our cells. If any of these potential neighbour cells is controlled by another RNC the RNSAP Information Exchange Initiation procedure may be used to request cell information from the neighbour RNC. In addition the Base RNC may interact with O&M before a neighbour relation is be stored in the NRT as
