28、RM (This page intentionally left blank) TIA TSB-100-A-2 Wireless NRM 5 Reference Models 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 wireless standards. 2.1 Wireless Network Ref
29、erence 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 model in this docum
30、ent is the compilation of several reference models currently in use in 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 physica
31、l 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 Center (AC). The ph
32、ysical 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 network entity is a physi
33、cal 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 are contained in d
34、ifferent 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. TIA TSB-100-A-2 Reference Models 6 Wireless NRM Figure 2.1 Wireless Network Refere

42、l 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 provides Internet Prot
43、ocol 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. An AC may serve m
44、ore 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. TIA TSB-100-A-2 Reference Models 8 Wireless NRM Base Station Controller (BSC) The BSC is an entity that provides control and management for one o
45、r more BTSs. The BSC exchanges messages with both the BTS and the MSC. Traffic and signaling concerned with 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 t
46、he Umreference point. The BTS consists of radio devices, antenna and equipment. Call Data Collection Point (CDCP) The CDCP is the entity that collects the DMH format call detail information. Call Data Generation Point (CDGP) The CDGP is an entity which provides call detail information to the CDCP in
47、 DMH 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 should be in ANSI-124 format. Call Data Information Source (CDIS) The CDIS is an entity that can be the source of call detail infor
48、mation. This information may be in proprietary format. It is not required to be in DMH format. Call Data Rating Point (CDRP) The CDRP is the entity that takes the unrated DMH format call detail information and applies the applicable charge and tax related information. The charge and tax information
49、is added using DMH format. Collection Function (CF) - Intercept The CF is an entity that is responsible for collecting intercepted communications for a lawfully authorized law enforcement agency. The CFs typically include: the ability to receive and process call contents information for each intercept subject. the ability to receive information regarding each intercept subject (e.g., call associated or non-call associated) from the Delivery function and process it. Coordinate Routing Data Base (CRDB) The CRDB is an ent
