1、 TIA-4940.005 HFember 2011 Smart Device Communications Reference Architecture 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 pro
2、ducts, 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 s
3、uch Standards 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) pa
4、tent 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 requireme
5、nts. 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.

37、HY and MAC) monitoring and bi-directional communication of events 4 and information between logical entities, such as Point-of-Attachment and 5 applications or networks. 6 This document provides an M2M smart device communication reference 7 architecture, describing functional elements and their inte
38、rconnection. The 8 reference architecture assumes some level of IP addressability as described 9 herein. The Annexes provide identified use cases and demonstrate the 10 applicability of the reference architecture to the support of those use cases. 11 The terms marked with italicized fonts are intend

48、plication: The node application is a logical entity that acts as an 13 intermediary between the home application and the PoA application and 14 between the home application and the PoA device. The node application 15 interacts with home application, other node applications, PoA application or 16 PoA
49、 device, and may perform functions such as a data aggregation, storage, 17 load balancing, etc. 18 PoA Application: PoA application is a logical entity that provides resources 19 to node or home applications or to other PoA applications. The PoA 20 application interacts with home, node, other PoA applications or with PoA 21 devices. The PoA application may perform functions such as autonomous 22 reporting of values reported by devices, monitoring for values reported by 23 devices that exceed specified limits, trend analysis of values
