1、 TSB-181-1 October 2011Ultra Mobile Broadband Network Architecture Model NOTICE TIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products
2、, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for their particular need. The existence of such Standards and Publications shall not in any respect preclude any member or non-member of TIA from manufacturing or selling products not conforming to such S
3、tandards and Publications. Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally. Standards and Publications are adopted by TIA in accordance with the American National Standards Institute (ANSI) patent
4、policy. By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements.
5、It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

The network entities are functional rep
43、resentations. b. A network entity represents a group of functions, not necessarily a physical device. The physical realization of a network entity is an implementation issue. A manufacturer may choose any physical implementation of network entities, either individually or in combination, as long as
44、the implementation meets the functional requirements. Sometimes, for practical specifications reasons, the functional network entity is interpreted as a physical device. c. A reference point is a conceptual point that divides two groups of functions. It is not necessarily a physical interface. One o
45、r more interfaces may be defined to support each reference point. d. Each reference point corresponds to at least one standardized interface. e. An interface is comprised of a standardized set of procedures, messages, and protocols. Interface specification is beyond the scope of this document. f. A
46、“Collective Entity” contains encompassed network entities that are an instance of the collective (e.g., UMB Access Network). 2.2 Network Entities 2.2.1 Access Gateway (AGW) The Access Gateway (AGW) is an entity that provides the users “point of IP connectivity” to the network. That is, the AGW is in
47、 effect the first-hop router for the mobile terminal. The AGW performs layer 3 services and above, including hot-lining, accounting, policy enforcement, etc. Additional information regarding the AGW, IP Multimedia Domain, Legacy MS Domain, and Broadcast/Multicast Service (BCMCS) is contained in 3. A
48、 split AGW configuration separates the AGW into a Serving-AGW (srv-AGW) and an Anchor-AGW (anc-AGW). 2.2.2 Access Network The Access Network is a network component that may support both the Multimedia and Legacy MS Domains. The access network may perform mobility management functions for registering
49、, authorizing, authenticating and paging IP based terminals, independent of circuit based terminals. The access network may perform handoffs within an access S.R0124-0 v2.0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 6 network and between access networks of the same technology and may support handoffs between access networks of differing technologies. 2.2.2.1 cdma2000 Access Network The cdma2000 1X Access Network and the HPRD A
