27、he purposes of the present document, the following terms and definitions apply: 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 i

28、s broadcasted over a geographical area from one UTRAN Access Point A Cell is either FDD or TDD mode. Iu: interface between an RNC and an MSC, SGSN or CBC, providing an interconnection point between the RNS and the Core Network. It is also considered as a reference point Iub: interface between the RN

29、C 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 interface between RNC/BSS and BSS Whilst logically representing a point to point link between RNC/BSS

30、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 network element, aggregations of network elements, the topological relationship between the elements

31、, 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 Model are used, among others, by connection management functions. In this way, a physical imp

32、lementation independent management is achieved. Node B: logical node in the RNS responsible 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

33、.g. frequencies, scrambling codes, spreading factors, power for common and dedicated 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: ro

34、le an RNC can take with respect to a specific set of Node Bs There is only one Controlling RNC for any Node B. The Controlling RNC has the overall control of the logical resources of its node Bs. Radio Network Subsystem: RNS can be either a full UTRAN or only a part of a UTRAN An RNS offers the allo

35、cation and release of specific radio resources to establish means of connection in between an UE and the UTRAN. A Radio Network Subsystem contains one RNC and is responsible for the resources and transmission/reception in a set of cells. ETSI ETSI TS 125 401 V5.6.0 (2003-06) 8 3GPP TS 25.401 version

36、 5.6.0 Release 5 Serving RNS: role an RNS can take with respect to a specific connection between an UE and UTRAN There is one Serving RNS for each UE that has a connection to UTRAN. The Serving RNS is in charge of the radio connection between a UE and the UTRAN. The Serving RNS terminates the Iu for

37、 this UE. Drift RNS: role an RNS can take with respect to a specific connection between an UE and UTRAN An RNS that supports the Serving RNS with radio resources when the connection between the UTRAN and the UE need to use cell(s) controlled by this RNS is referred to as Drift RNS. Radio Access Netw

38、ork Application Part: Radio Network Signalling over the Iu Radio Network Subsystem Application Part: Radio Network Signalling over the Iur RRC Connection: point-to-point bi-directional connection between RRC peer entities on the UE and the UTRAN sides, respectively An UE has either zero or one RRC c

39、onnection. Standalone A-GPS SMLC: logical node that interconnects to the RNC over the Iupc interface via the PCAP protocol This node provides GPS related data to the RNC and may perform the position calculation function. User Equipment: Mobile Equipment with one or several UMTS Subscriber Identity M

40、odule(s) A device allowing a user access to network services via the Uu interface. The UE is defined in ref. 8. If this term is used in the context of Iur-g, it means MS in case it uses radio resources of a DBSS. Universal Terrestrial Radio Access Network: UTRAN is a conceptual term identifying that

41、 part of the network which consists of RNCs and Node Bs between Iu an Uu The concept of UTRAN instantiation is currently undefined. UTRAN Access Point: conceptual point within the UTRAN performing radio transmission and reception A UTRAN access point is associated with one specific cell, i.e. there

42、exists one UTRAN access point for each cell. It is the UTRAN-side end point of a radio link. Radio Link: “radio link“ is a logical association between a single User Equipment and a single UTRAN access point Its physical realisation comprises one or more radio bearer transmissions. Radio Link Set: se

43、t of one or more Radio Links that has a common generation of Transmit Power Control (TPC) commands in the DL Uu: Radio interface between UTRAN and the User Equipment RAB sub-flows: Radio Access Bearer can be realised by UTRAN through several sub-flows These sub-flows correspond to the NAS service da

44、ta streams that have QoS characteristics that differ in a predefined manner within a RAB e.g. different reliability classes. RAB sub-flows have the following characteristics: 1) The sub-flows of a RAB are established and released at the RAB establishment and release, respectively. 2) The sub-flows o

45、f a RAB are submitted and delivered together at the RAB SAP. 3) The sub-flows of a RAB are carried over the same Iu transport bearer. 4) The sub-flows of a RAB are organised in a predefined manner at the SAP and over the Iu interface. The organisation is imposed by the NAS as part of its co-ordinati

46、on responsibility. Set of co-ordinated DCHs: set of co-ordinated DCHs is a set of dedicated transport channels that are always established and released in combination Individual DCHs within a set of co-ordinated DCHs cannot be operated on individually e.g. if the establishment of one DCH fails, the

47、establishment of all other DCHs in the set of co-ordinated DCHs shall be terminated unsuccessfully. A set of coordinated DCHs is transferred over one transport bearer. All DCHs in a set of co-ordinated DCHs shall have the same TTI. Shared Network Area (SNA): Area consisting or one or more LAs to whi

48、ch access can be controlled.
