IS-725 TIAlEIAIIS-725-A, Cellular Radiotelecommunications Intersystem Operations - Over-The-Air Service Provisioning (OTASP) the reference poin
23、ts are represented by circles. The network reference model 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
24、a physical device. For example, a Mobile Switching Center (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),
25、the Home Location Register (HLR), and the Authentication 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
26、. Sometimes, for practical reasons, the functional network 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
27、 interface when the network entities on either side of it 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. 1 2 3

See Section 2.1.2 for the definition
35、of the Reference Points associated with each Network Entity. Authentication, Authorization and Accounting (AAA) The AAA is an entity that provides Internet Protocol functionality to support the functions of Authentication, Authorization and Accounting. Authentication Center (AC) The AC is an entity
36、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 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
37、BSC and a BTS. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 a) 21 22 23 24 25 26 27 23 29 33 31 3 33 34 5 33 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 E6 56 57 58 59 Reference Model 6 TR-45 Wireless NRM TSBl OO-A 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 a) 21 22 23 24 25 26 27

The BSC exchanges messages with both the BTS and the MSC. Traffic and signaling concerned wit
39、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 Um reference point. The BTS consists of radio devices, antenna and equipment. Call Data Collection Poin
40、t 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 for
41、mat into the ANSI-124 format. All information from the CDGP to the CDCP must 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 may be in proprietary format. It is not required to be in ANSI-124 format.
42、 Call Data Rating Point (CDRP) The CDRP is the entity that takes the unrated ANSI-124 format call detail information and applies the applicable charge and tax related information. The charge and tax information is added using ANSI-124 format. Collection Function (CF) - Intercept The CF is an entity
43、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
44、., call associated or non-call associated) from the Delivery function and process it. Coordinate Routing Data Base (CRDB) The CRDB is an entity which stores information to translate a given position expressed as a latitude and longitude to a string of digits. Customer Service Center CSC The CSC is a
45、n entity where service provider representatives receive telephone calls from customers wishing to subscribe to initial wireless service or request a change in the TR-45 Wireless NRM 7 Network Entities TSBl OO-A customers existing service. The CSC interfaces proprietarily with the OTAF to perform net
46、work and MS related changes necessary to complete the service provisioning request. Data Circuit Equipment (DCE) A termination that provides a non-ISDN user-network interface (e.g., ITU-T CCITT V series, ITU-T CCITT X series). Delivery Function (DF) - Intercept The DF is an entity that is responsibl
47、e for delivering intercepted communications to one or more collection functions. The DFs typically include: the ability to accept call contents for each intercept subject over one or more channels from each Access function. the ability to deliver call contents for each intercept subject over one or
48、more channels to a Collection function as authorized for each law enforcement agency. the ability to accept information over one or more data channels and combine that information into a single data flow for each intercept subject. the ability to filter or select information on an intercept subject
49、before delivery to a Collection function as authorized for a particular law enforcement agency. the optional ability to detect audio in-band DTMF digits for translation and delivery to a Collection function as authorized for a particular law enforcement agency. the ability to duplicate and deliver information on the intercept subject to one or more Collection functions as authorized for each law enforcement agency. the ability to provide security to restrict access. Emergency Service Message Entity (ESME) The ESME routes and processes the out-of-band messages r
