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 Wirel
34、ess Network Reference Model Figure 2.1 presents 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 mode
35、l in this document is the compilation of several 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
36、 (MSC) is a physical device; it comprises frames, 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
37、Center (AC). The physical realization is an implementation 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 networ
38、k entity is a physical device. The Mobile Station (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
39、 are contained in different physical devices. 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. Copyright Telecommunications Industry Association Provided by I
