39、ned as the multi-frequency cell. 1.28Mcps TDD - Primary frequency: In a multi-frequency cell, the frequency on which the P-CCPCH is transmitted is defined as primary frequency. 1.28Mcps TDD - Secondary frequency: In a multi-frequency cell, any frequency other than the primary frequency is defined as
40、 secondary frequency. ALCAP: generic name for the transport signalling protocols used to set-up and tear-down transport bearers Cell: Radio Network object that can be uniquely identified by a User Equipment from a (cell) identification that is broadcasted over a geographical area from one UTRAN Acce
41、ss Point A Cell is either FDD or TDD mode. ETSI ETSI TS 125 401 V14.0.0 (2017-04)93GPP TS 25.401 version 14.0.0 Release 14DCN-ID: DCN identity identifies a specific decicated core network (DCN). Iu: interface between an RNC and an MSC, SGSN or CBC, providing an interconnection point between the RNS
42、and the Core Network. It is also considered as a reference point Iub: interface between the RNC and the Node B Iur: logical interface between two RNCs Whilst logically representing a point to point link between RNCs, the physical realisation need not be a point to point link. Iur-g: logical interfac
43、e between RNC/BSS and BSS Whilst logically representing a point to point link between RNC/BSS and BSS, the physical realisation need not be a point to point link. Logical Model: Logical Model defines an abstract view of a network or network element by means of information objects representing networ
44、k element, aggregations of network elements, the topological relationship between the elements, endpoints of connections (termination points), and transport entities (such as connections) that transport information between two or more termination points The information objects defined in the Logical
45、 Model are used, among others, by connection management functions. In this way, a physical implementation independent management is achieved. Network sharing supporting UE: as defined in TS 23.251 28. Network sharing non-supporting UE: as defined in TS 23.251 28. Node B: logical node in the RNS resp
46、onsible for radio transmission / reception in one or more cells to/from the UE The logical node terminates the Iub interface towards the RNC. Radio Resources: resources that constitute the radio interface in UTRAN, e.g. frequencies, scrambling codes, spreading factors, power for common and dedicated
47、 channels Node B Application Part: Radio Network Signalling over the Iub Radio Network Controller: logical node in the RNS in charge of controlling the use and the integrity of the radio resources Controlling RNC: role an RNC can take with respect to a specific set of Node Bs There is only one Contr
48、olling RNC for any Node B. The Controlling RNC has the overall control of the logical resources of its node Bs. MBMS Master RNC: role an RNC can take with respect to one or more specific MBSFN cluster(s) MRNC may be used for Inter-RNC MBSFN operation whenever dynamic synchronization of radio resourc
49、es used for MBMS services is centrally controlled. There is only one MBMS Master RNC for any MBSFN cluster, which may control one or more MBSFN cluster(s). The MRNC has the overall control of the logical resources of the RNSs that are used for MBSFN operation within the MBSFN cluster(s). Radio Network Subsystem: RNS can be either a full UTRAN or only a part of a UTRAN An RNS offers the allocation and release of specific radio resources to establish means of connection in between an UE and the UTRAN.
