QoS regulations
Measurement and reporting are expensive
Do you scratch everywhere? or scratch
where it itches?
Need to focus on the known problem
areas
But the problem areas may change over
time
Issue of cost effectiveness

Service Level Agreements
Considered highly important
Indication of the level that the supplier aims to
achieve
Only tangible benefit if there is compensation
for failure
Is the compensation a token or a rebalancing of
the failure
A token at least imposes some incentive to
perform
Tokens are noticed by management

Criteria for QoS Parameters
QoS parameters should be easily understood by the public, and be useful
and important to them.
All parameters are applicable at the network termination point. Where
measurements are possible, they should be made on the customer's
premises, using in-service lines. To be as realistic as possible, real traffic
rather than test calls should be used as a basis of the measurements,
wherever possible.
Parameters should be capable of verification by independent organizations.
This verification might be made by direct measurements or by audit of the
operator's measurements.
The accuracy of QoS parameter values should be set to a level consistent
with cost effectively available measurement methods.
The parameters are designed for both statistical and individual application.
The statistical values should be derived by the application of a simple
statistical function to the individual values. The statistical function should be
specified in the standard. The standard should also contain guidelines on
how statistically significant samples should be selected.

Regulation and Customer Compensation
Initial levels of compensation should be low
Any such payments will be monitored by management of operators
Experience is that the benefit in alerting management to problems far
exceeds the value of the sums paid as they expose mangers to internal
criticism
However for critical parameters that have a seriously damaging
effect on customers
Levels of compensation should rise depending on the extent on the
problem with higher payments to business customers than to residential
ones
For example failure to repair a fault within a specified time would incur a
penalty of say $X per day
this rate should not be capped at a maximum of say 5 days but continue
possibly rate per day should rise if the time exceeds say 10 days
This formulation is needed to ensure that the managers concerned take
appropriate steps to resolve the issues and prepare adequately for the
problems that inevitably will occur.

Regulatory Aspects (1)
QoS parameters for Regulation should be
Limited in number
Focus to hot topics
where problems already exist or expected to occur soon
Taylored to the special situation in the Region
different topics for each country
Maputo - Mozambique - 14 - 16 April 2014
8
Regulatory Aspects (2)
Network operators but also customers have experience
with regulation & resulting QoS in other countries of the
region
For National Regulators it is important to prove
customized regulation regime
but no re-invention of the wheel
no over burdening of operators
Maputo - Mozambique - 14 - 16 April 2014

Best Practice
Some Advantages (postulated)
QoS Regulation not needed
Market Powers regulate overall Quality
Some Requirements (obvious)
All Stakeholders Stick to Standards
Appropriate Standards are available in Time
QoS Responsibilities must be clear defined
Some Problems (surprise !)
„connect your fridge to the network – it might be legal“
Maputo - Mozambique - 14 - 16 April 2014

Market Mechanisms
Forces of the Market will bring users into a position where they can obtain the endto-end QoS they wish to perceive
Has been postulated for a long time in Europe
Has been proven to be more than questionable
Mostly, contracts between users and network operators
have a longterm binding character
do not contain any QoS provisions
Currently, traditional Telcos have no incentive to provide high end-to-end QoS for
their NGN customers
Number of customers remains stable
In parallel the commercial company value
In contrast are Internet based communication service providers
Receive their revenue not directly from users
But by other business models which rely on a high (and increasing) number of users of the
service every day
Customers not satisfied with end-to-end QoS will stop using the service
Consequently the number of customers decreases immediately and so the company value
Thus the incentive to offer high end-to-end QoS to the user is extremely high.

Absolute Minimum
Average over Usage/Regions/Calendar Time
Specification of QoS & NP Parameters
End-to-End
For each Network Element & Terminals
Selection of Reference Connections
Typical Connections (High # of Occurence)
Complex Connections (QoS Problems expected)
Legal Regulatory Framework
To enforce Requirements
To strengthen Customers‘ Rights
To solve issues in Cases of not achieved QoS

Transmission Planning in Europe (1)
Historically, separate national transmission plan have been enforced and
utilized in European countries:
National transmission plans based on ITU-T (CCITT) Recommendations
Inter-Country, intra-European telephony connections ruled by
The International transmission plan as per ITU-T Recommendations G.101, G.111
and G.121
Regulatory Treatment of a Telephony Connection in Europe consists of two
parts:
Regulation of the public network (through the Directives on an Open Network
Provision) and
Regulation of the terminal market (through a “Terminal Directive")
Both of these regulations are undergoing changes with the effect that national
regulatory authorities do not intervene where quality is ensured through
effective competition
The new directive for Radio equipment and Telecommunications Terminal
Equipment (the "R&TTE" directive) includes a possibility for the Commission
to issue regulation regarding voice performance.
Maputo - Mozambique - 14 - 16 April 2014
15
Transmission Planning in Europe (2)
As long as the market actors behave in a responsible
manner, there will be no EU regulation of voice
performance of customer premises equipment
connected to a public network
For the telecommunications industry it is however of
value to arrive at a common transmission plan for
future networks, to ensure successful global
communications
Pan-European Loss Plan has been developed
ETSI ES202020 harmonized with TIA
To assist manufacturers in achieving satisfactory voice
performance
Not a regulatory requirement

Some Conclusions ...
Focus on User perceived Parameters
users do not understand network specific KPIs
End-to-end QoS is different
On-net vs. Off-net
National vs. International
On the other hand
User trend to global communication

Initial Conclusions
Conclusion of the German Regulator:
Quality extremely fluctuating and not predictable
An global average quality value across one mobile network
has no meaning for the customer
(e.g. average UMTS download speed for T-Mobile across Germany =
3 Mbit/s)
Customer wants to know quality at current location
High resolution required for measurements to be of any use
for customer
Measurements of quality anddisplay of results must always
reference Time and Location
Averaging across entire infrastructures not permitted

Future Work
Development of a measurement methodology for broadband
access speed
measurement will be done by customers
creation of a public data base across all providers
enable customers to know the quality before signing the contract
enable customers to check the contracted quality
Consequences for Mobile Operators:
make your own drive test with very high granularity "postal code level"
or
make software measurement on your customers' phones
Approach via customers' phones requires huge data base
On average results per location will "true values"
Software must account for terminal aspect in intelligent manner
Currently under development by German Regulator
