Context – Challenges - Issues

Mobile operators are deploying IMS and VoLTE

NEW operator/Carrier challengesMake IMS interconnection possible and simple

Technically

Commercially

Bilateral but also Hubbing

We need the key information to interconnect IMS networks

• B operator identity (“is B operator an IMS operator ?”)

ENUM Framework enables IMS interconnection

• ENUM or Non ENUM can be used to retrieve routing information

• Number Portability management is no more a blocking point to retrieve B Operator identity

• ENUM Proxies could delegate queries and are not obliged to connect to all B operators (facilitate connectivity to B operator databases)

• Moreover, access to B operator DB is limited and is more secured.

Advantage!
