This document provides the Network Architecture Model (NAM) for the Ultra Mobile Broadband (UMB) system.

PURPOSE

This document provides the Network Architecture Model (NAM) for the Ultra Mobile Broadband^TM (UMB^TM)¹ system. The NAM supports the requirements in S.R0121 [1] and the Phase II requirements in S.R0113 [2].

The UMB system provides an additional Access Network (AN) to the overall architecture document in the All-IP NAM [3]. Except as documented in this document, all reference points and network entities in [3] are hereby incorporated by reference. Note: If not explained in this document, then refer to All-IP NAM [3].

This document was developed in conjunction with the network reference model of X.S0054-000-A [4] and TSG-X updates.
