Concepts and Benefits of IPX

Key Commercial Requirement For IPX• End-to-End service delivery

– emphasis on Quality of Service and universal charging principles;

• Service interoperability– global service inter-working (fixed & mobile, ISP & ASP’s);

• Third party

management– managed access, interconnect agreement, SLA;

• Customer

protection– against misuse e.g. spam, identity theft, fraud, invasion of

privacy, etc.• Cascade payments

– equitable and sustainable division of revenue in service delivery chain;

• Supporting

value-based

service pricing– reflecting the value of services to the consumer;

• Customer

choice– The consumer will make the choice on their preferred access

method to enable their communication; • Ease of use

– Should be transparent to the consumer;


GRX – Simple data interconnectivity

• Interconnect & roaming 2.5G and 3G data;

• Private to GSM community;

• No recognition of services transported;

• Best effort system;• No interconnect settlement

regime;

• Good for email• Not good for VoIP• Not good for video


IPX – Rich IP services interconnectivity

• All IP multimedia players may be connected;

• No relaxation of security;• Recognition of services

transported;• Cascading service

payment regime; • Circuit equivalent quality

of service;

• Good for email• Good for VoIP• Good for video

End-to-End Service Delivery• IPX focuses on end-to-end quality through a cascading

responsibility concept;• Each party will be responsibly for the performance of the next

party in the transit chain– IPX’s will commit to Service Providers and other IPX’s– Service Providers will commit to IPX’s where it provides the

local tail connection.• All parties will be subject to an SLA • Each area of the system is covered, including

– Local tail– Peering points/Interconnect Points

• The SLA for each service will detail the performance requiredSP B

IP Services on the IPX•

IPX Services are

standardised–

Common charging principle–

Technically inter-operable end to end

•

Operators negotiate which services they want with IPX carriers

•

Agreements specified in a Contract Service Schedule containing–

SLA–

Connectivity model–

Operator interconnection list–

Etc•

Roaming can be regarded as an IPX service particularly where QoS is required


IPX Framework

IPX offers -

global reach, one to many relationships, connects

MNOs,

FNOs

and ISPs, enabling IP Interoperability over a secure, sustainable and high quality IP network.

Summary of Key Benefits of IPX• End To End QoS

- Will enable end to end QoS for all IP Services enabling consistent and predictable service delivery between end customers;– Services that require high QoS will be prioritised over less

demanding services;– SLA will apply equally over two IPX’s.

• Secure Network

- A highly secure network enabling full route traceability and connectivity between “trusted” entities;

• Sustainable Commercial Model

- Enabling fair remuneration to all parties involved in the service delivery underpinning SLA ;

• Universal Interoperability

– can connect different communities (MNO, FNO, ISP, ASPs etc) to enable universal service interoperability;

• Highly Efficient and Scaleable. Single connection and commercial agreement enables connectivity to all Services Providers connection to the IPX environment.
