SUBSCRIBER BASE (end of 2009)SUBSCRIBER BASE (end of 2009)

Partial missing of vendor’s committed implemented functionalities affects general quality of services No separate organization or office responsible to verify and assess the quality and

functionality pre-declared by vendors Telcos don’t have sufficient experience in verifying quality and capacity of the

systems as well as a standard Test Lab to conduct the testing and conformity assessment of the equipment’s quality

Affect the quality of service delivered to customers

Ex: • It was not possible to implement vendor H’s EMR function in V’s mobile wireless

network.• In transmission network, vendor H’s SDH equipment Metro 100 lacks of LCAS

function

Interoperability and Conformity AssessmentInteroperability and Conformity Assessment

Partial lack of interoperability between equipment of same or different manufacturers results in the impossibility to access to services ITU recommendations and 3GPP specifications may have many

optional features and parameters but vendors sometimes choose only some but not all those optional features and parameters

Incompatibility of equipments from different suppliers

Ex: • For EoS service (Ethernet over SDH), equipments of many suppliers

can not be configured inter-networking (in fact, in telco V’s case, equipments of supplier E, H, Z could not be inter-networking configured)

Interoperability and Conformity Assessment (Cont)

Interoperability and Conformity Assessment (Cont)

Need to apply unexpected procedures to obtain that functionalities work lack of ITU recommendations to map in while the development of

new end-user equipments and network equipments is getting more and more diversified

Telco has to look for another standard body or forum to refer to

Ex: • For NGN network that provides VoIP and multimedia services, there

are many types of end-user equipments such as ATA, HomeGateway and IP phones but it is not true that every terminal will be compatible with the existing NGN that Telco has already invested using equipments from one supplier

Interoperability and Conformity Assessment (Cont)

Interoperability and Conformity Assessment (Cont)

Equipment lack of conformity with standards Most of equipments supplied by vendors to build the

network are declared to be compliant to international standards but there are not concrete proofs or clear binding.

Mandatory and optional terms are applied in different way for each operator/telco or supplier. Optional features can affect connections and interoperability between equipments and quality of service.

Interoperability and Conformity Assessment (Cont)

Interoperability and Conformity Assessment (Cont)

• ITU should open a channel to assist telcos to solve all mentioned problems.

• Viet Nam call for ITU’s assistance and sponsoring for training and building a standard Lab for assessing and testing quality and capacity of telecom network equipments (not only terminal equipments) from suppliers.

• ITU should help telcos and request vendors to cooperate with telcos in dealing with non-interoperability.

• ITU would produce guidelines for developing countries in applying ITU recommendations and build our own national standard system for NGN/IP/3G in which specifications and parameters are chosen suitable with the conditions of Viet Nam as well as other countries in the region.

• ITU should consider holding the workshop on the administrative role in conformity assessment including best practice and experience of developed countries in this issue.
