Unified Communications (UC) over IP Multimedia Subsystem (IMS): Solutions and Market/Business Analysis?
Unified Communications over IP Multimedia Subsystem?Market?
Description
IP Multi-media Subsystem (IMS) is defined by various standard body include 3GPP, TISPAN, etc. It?s a fully standardized architecture with detailed definition of interface/protocol/procedures. It?s a platform enabler facilitating a multi-tenant environment, including residential users, wireless users and enterprise UC users.
This report includes both technical information (technology, architecture, solutions) as well as business information (SWOT analysis of key players/offerings, application evaluation, business case, and market forecasting) for UC over IMS. Players/solutions evaluated include 8?8, Apple, AT&T, Google, and Telstra. The report also analyzes UC feature/functionality including presence, IM, UM, team collaboration, conference and telephony servers. The report also evaluates call/session scenarios in operation and applicability for UC over IMS deployment.
Audience:
- Fixed and mobile network operators
- Application and software development companies
- IMS and NGN infrastructure and support service providers
