TC INT Achievements

TC INT has produced IMS NNI interoperability

and conformance test specifications :

• 3GPP R6/TISPAN R1

• 3GPP R7/TISPAN R2

• 3GPP R8

The TC works in liaison with TISPAN WG6 for

the topics across NGN/IMS.

TC INT Achievements

TC INT has produced Interoperability Test

Specification on ISC Interface on request of

GSMA RCS GSMA RCS

TC INT is working in Liaison with GSMA IREG for

the NNI R8 Interoperability which is the base for

the VoLTE profile.

TC INT acts as steering committee for the IMS

Interoperability Event organization.

ETSI IMS Interoperability Event:

IMS Plugtests

The events are open for participation for IMS

equipment vendors and operators, as well as

ETSI members and non-members.

Test Specification are publicly available and Test Specification are publicly available and

written by ETSI TC INT.

Formal TTCN3 verification are carried on

Interoperability and Conformance

ETSI IMS Interoperability Event:

IMS Plugtests

Vendor participating to ETSI Plugtests can have

Plugtests Participation certificate towards their

customers

Vendors have the opportunity to show selected

demonstrations of the latest IMS services and demonstrations of the latest IMS services and

applications like rich communication services (RCS),

also potentially involving mobile devices, as well as

IMS testing tools.

Operators have the opportunity to get information to

apply in internal RFI/RFQ

LTE Introduction will produce a further

increase of IP Address Needsincrease of IP Address Needs

LTE will be a further driver for IPV6
