Major Trends Voice Evolution

CS domain remains predominant for mobile voice wellinto the next decade

Operators key differentiators are cost position and voicequality

IMS becomes uniform service control for all types of

traffic in long-term Introduction is driven by new multimedia services

IMS is multimedia soft switch

IMS will be used for voice applications (e.g. PoC or rich

voice) Migration to SIP controlled voice via IMS will start with wire

line and alternate accesses (e.g. WLAN)

In the long run SIP controlled voice via IMS will replace theCS voice

What Is NGN in Mobile Networks?

NGN blends the public switched telephone network(PSTN) and the public switched data network (PSDN)

Creates a single multi-service network

Not based on large, centralized, proprietary switchinfrastructures

Results in a distributed network infrastructure

Leverages new, open technologies to reduce the cost ofmarket entry

Increase flexibility

Accommodate both circuit-switched voice and packet-switched data

Soft-switching technology

NGN in Mobile Networks

For CS domain NGN = R4 R4 specifies the separated architecture (MSC-S and MGW)

For CS domain FMC = R5/R6
