1 Introduction
This chapter provides a brief description of the A-Port feature of the Oracle Communications EAGLE. The chapter also includes the scope, audience, and organization of the manual; how to find related publications; and how to contact Oracle for assistance.
1.1 Overview
This manual provides feature descriptions, commands, maintenance, measurements, and configuration details associated with the ANSI-41 Mobile Number Portability (A-Port) feature of the EAGLE and other features related to the A-Port feature. A-Port provides number portability functionality using a triggerless solution. Although the A-Port feature applies to ITU and ANSI networks, the A-Port feature focuses on service provider number portability on ANSI networks.
A-Port minimizes the challenges for network operators while enabling them to meet their regulatory obligations. A-Port supports the Signaling Relay Function (SRF) for direct and indirect routing. SRF-based MNP processing examines MAP messages for ported numbers. For call-related messages, A-Port acts as an “NP HLR” for exported number by responding with a MAP SRI message; A-Port performs a message relay function for calls to imported numbers and non-call related messages.
A-Port optimizes the use of subscriber numbers and number ranges in a Mobile Network by providing a Mobile Directory Number (MDN) and any International Mobile Station Identifier (IMSI). The feature allows subscribers to be moved easily from one Home Location Register (HLR) to another.
A-Port is an optional feature on the EAGLE, and can be enabled and turned on, but not off, via a feature access key. Note that A-Port requires the Global Title Translation (GTT) feature. A-Port and North American LNP (Local Number Portability) are mutually exclusive on an EAGLE, unless the Dual ExAP Configuration feature is enabled.
1.2 Scope and Audience
This manual is intended for anyone responsible for installing, maintaining, and using the A-Port feature in the EAGLE. Users of this manual and the others in the EAGLE family of documents must have a working knowledge of telecommunications and network installations.
