29、58 59 60 Reference Model 4 TR-45 Wireless NRM 2. REFERENCE MODELS Reference models are a graphical tool used to visualize, structure, and describe certain complex subjects. A few such models are widely used in the TR-45 wireless standards. 2.1 TR-45 Wireless Network Reference Model Figure 2.1 presen
30、ts the network entities and associated reference points that comprise a wireless network. The network entities are represented by squares, triangles and rounded corner rectangles; the reference points are represented by circles. The network reference model in this document is the compilation of seve
31、ral reference models currently in use in TIA wireless standards. Note the following: The network reference model is a functional block diagram. A network entity represents a group of functions, not a physical device. For example, a Mobile Switching Center (MSC) is a physical device; it comprises fra
32、mes, shelves, circuit packs, etc. The physical device may comprise a single network entity such as the MSC, or it may comprise some combination such as the MSC, the Visitor Location Register (VLR), the Home Location Register (HLR), and the Authentication Center (AC). The physical realization is an i
33、mplementation issue; a manufacturer may choose any physical implementation of network entities, either individually or in combination, as long as the implementation meets the functional requirements. Sometimes, for practical reasons, the functional network entity is a physical device. The Mobile Sta
34、tion (MS) is an excellent example. A reference point is a conceptual point that divides two groups of functions. It is not necessarily a physical interface. A reference point only becomes a physical interface when the network entities on either side of it are contained in different physical devices.
35、 A “Collective Entity” contains encompassed network entities that are an instance of the collective. A “Composite Entity” contains encompassed network entities that are part of the composite.

44、ty may be a physical device, may form part of a physical device, or may be distributed over a number of physical devices. See Section 2.1.2 for the definition of the Reference Points associated with each Network Entity. Authentication, Authorization and Accounting (AAA) The AAA is an entity that pro
45、vides Internet Protocol functionality to support the functions of Authentication, Authorization and Accounting. Authentication Center (AC) The AC is an entity that manages the authentication information related to the MS. The AC may, or may not be located within, and be indistinguishable from an HLR
46、. An AC may serve more than one HLR. Base Station (BS) A BS is an entity that provides the means for MSs to access network services using radio. It includes a BSC and a BTS.

The BSC exchanges messages with both the BTS and the MSC. Traffic and signaling concerned wit
48、h call control, mobility management, and MS management may pass transparently through the BSC. Base Transceiver System (BTS) The BTS is an entity that provides transmission capabilities across the Umreference point. The BTS consists of radio devices, antenna and equipment. Call Data Collection Point
49、 (CDCP) The CDCP is the entity that collects the ANSI-124 format call detail information. Call Data Generation Point (CDGP) The CDGP is an entity which provides call detail information to the CDCP in ANSI-124 format. This may be the entity which converts call detail information from a proprietary format into the ANSI-124 format. All information from the CDGP to the CDCP mustshould be in ANSI-124 format. Call Data Information Source (CDIS) The CDIS is an entity that can be the source of call detail information. This information
