Summary:
The purpose of this document is to clearly define the business requirements for Wireless Intercarrier Communications Interface Specification (WICIS) for Local Number Portability. It is the first volume, in the set of four, defined within the Unified Ordering Model (UOM) process. WICIS was converted to UOM in order to align with technology changes and to better facilitate interoperability.The primary audience for this specification document is Commercial Mobile Radio Service (CMRS) providers along with wireless equipment and service vendors who assist in the definition, development and deployment of Wireless Number Portability (WNP) solutions. It assumes the reader is familiar with WNP and the wireless telecommunications technologies. WICIS defines the operational requirements and technical specifications for the exchange of information needed for the Intercarrier Communication Process (ICP). It represents a consensus developed by the members of the OBF Wireless Committee and is applicable to all CMRS carriers. Proprietary implementations are outside the scope of WICIS.WICIS defines number portability intercarrier communications processes for wireless providers. References to wireless interactions with a wireline provider through fields, values or processes within WICIS have been identified to allow for the potential synchronization with intermodal processes and internal company system implementation efforts.WICIS is not intended to supersede any regulatory decision regarding number portability or intercarrier communications, but is intended to describe the process and specifications as it involves CMRS.
Table of Contents:
WICIS Volume I
This document provides an explanation of the business requirements and a conceptual overview of the solution. This conceptual overview is high-level. It defines “what” the user initially sees as the problem and “how” the user sees the business solution.
WICIS Volume II
Analysis may be seen as using the requirements and developing a more detailed understanding of the scope. In effect, this step defines “what” the proposed technical resolution needs to support. It is a logical view of the proposed solution which meets the business need.
WICIS Volume III
The logical view of the proposed resolution (model), created in the Analysis Phase, is translated into the language appropriate for the selected implementation technology. Design focuses on “how” the implementation shall resolve the business requirements. This volume also contains implementation details.
WICIS Volume IV
Volume IV contains generic guidelines for Joint Implementation Agreements (JIAs) not pertaining to the wireless industry. The OBF Wireless Committee publishes WICIS as a standard for all wireless companies and vendors. The transport protocol and interface records are implemented uniformly across the wireless industry.
