ANR Automatic Neighbour Relation eNB eNodeB or evolved NodeB NR Neighbour cell Relation NRT Neighbour cell Relation Table UC Use Case 4 Concepts and background For E-UTRAN, the ANR function in the eNB relates to the Use Cases Establishment of new eNB in network and Optimisati
34、on of the neighbourhood list in 4. - For Establishment of new eNB in network. If the operator so chooses, the OAM system adds and configures NRs before the eNB goes into operation. - For Optimisation of the neighbourhood list, the ANR function deals with automatic NR additions and removals. It minim
35、izes the need for planning and configuring NRs. If the operator so chooses, the OAM system adds and configures NRs or removes NRs after the eNB goes into operation. For UTRAN, the ANR function concept and overall description is documented in TS 25.484 8. - The ANR function in RNC allows OAM system t
36、o manage the NRT. OAM system can add and delete NRs and also change the attributes of the NRs. The OAM system is informed about changes in the NRT made by ANR function. 5 Requirements 5.1 Business level requirements REQ-ANR-CON-001 NRs shall be set up and optimized with no or minimal human intervent
37、ion. REQ-ANR-CON-002 For E-UTRAN, initial status of the newly created NR by ANR function shall be such that HO is allowed, X2 connection setup is allowed, and the NR is allowed to be removed by ANR function in eNB. REQ-ANR-CON-003 E-UTRAN ANR supports management of NRs from E-UTRAN to E-UTRAN, from
38、E-UTRAN to UTRAN, from E-UTRAN to CDMA2000 and from E-UTRAN to GERAN. REQ-ANR-CON-004 For UTRAN, initial status of the newly created NR by ANR function shall be such that HO is allowed and the NR is allowed to be removed by ANR function in RNC. REQ-ANR-CON-005 UTRAN ANR supports management of NRs fr

If the IRPManager finds out that a desired Neighbour Relation has not been added by ANR, the IRPManager may “Whi

Traceability (*) REQ-ANR-FUN-10, REQ-ANR-FUN-26 5.2.4.3 Handling of noX2 attribute Use Case 1 IRPManager needs to be able to forbid and allow the
48、 establishment of X2 interfaces from the source macro eNBs to a target eNB. IRPManager is aware that the target eNB cannot support X2 connections. This UC on how noX2 is used relates to node level rather than cell level. Use Case 2 IRPManager needs to be able to allow and forbid the establishment of
49、 X2 interfaces from the source HeNBs to a target macro eNB. This UC supports the case when a potentially large number of HeNBs in the vicinity of a macro eNB, X2 establishment requests from HeNB might saturate the physical ports of the macro eNB (not in terms of bandwidth saturation but rather the saturation in terms of the number of simultaneous establishment requests supported). This UC on how noX2 is used relates to node level rather than Cell level. Use Case 3 IRPManager needs to be able
