Ericsson sole supplier for IMS and MMTel solution

Significant savings in all OPEX areas

– 1600 core switching sites reduced to ~30 IMS sites

– 7800 access sites dismantled

– energy savings alone will finance the transition in 2 years

Broadband introduction changed the rules for competition

– Not profitable with narrowband access modernization

– Voice not enough to maintain PSTN market share

– New revenue streams from potential new services such as BCS, IPTV etc.

Progress and success achieved through

– Proof-of-Concept to ensure IMS quality and maturity

– Understanding of end-user behavior and segmentation

IMS = IP Multimedia Subsystem

› IP means

–The Internet Protocol used for datacom

› Multimedia means

–Voice, Video, Messaging, etc

› Subsystem means

– It is an inherent Part of the Global 3GPP standard

› IMS handles media and signalling over IP, real time

› IMS uses SIP for signalling (Session Initiation Protocol)

3GPP = 3rd Generation Partnership Program, a global alliance for standardising communication platforms and services
