文档介绍：Implementing a mobile munications (UC) solution
In the first part of this series, we defined munications (UC) and identified the major benefits anization could reap through its implementation. This second part addresses the major strategies that are available to implement a mobile UC solution and its simpler cousin, fixed mobile convergence (FMC).
The increased availability and reliability of works has made it possible to mobilize UC. However, there are two types of works on which works will depend: wireless LANs and cellular services. Wireless LAN limits the range of the coverage, but once work is installed, usage is essentially free. Cellular services can extend to mobile users nationwide, and potentially worldwide, but that ubiquitous access entails service charges. To get the best of both, enterprises are pursuing fixed mobile convergence solutions that provide the ability to integrate public cellular with private wired and works.
Two paths to fixed mobile convergence -- cFMC and eFMC
Fixed mobile convergence describes the ability to integrate public cellular with private works, both wired and wireless, and pass calls between them. Various FMC solutions are available to enterprise users, and they can be differentiated on three primary metrics:
1. Control point: Carrier-controlled (cFMC) or enterprise-controlled (eFMC).
2. Handoff capability: None, manual handoff, o
