Advantages and customer value
Multi terminal experience consistent
The UC business goes beyond fixed PC communications over the Internet，Emphasis on mobility，Realize the interworking of mobile / fixed line and PC client。Compared to ordinary mobile / fixed line subscribers, there is only one way of calling mobile / fixed terminal，UC users can use both mobile / fixed line and PC clients、Mobile client、IP phones and other terminals，Using voice、news、Short message、Conference and other means of communication for borderless communication，Thus more convenient and effective realization of communication。
The industry's leading voice quality
HUAWEI UC solutions，Using HUAWEI HME2.0 platform，Realize the automatic adjustment of speech quality。HME2.0 adopts Opus encoding and decoding algorithm。The Opus codec algorithm is designed for processing broadband network interactive audio applications，These applications include voice transmission over IP networks as well as video conferencing，Even real-time live music transmission。The HME2.0 sample rate is supported from narrowband 8KHz (minimum call request) to 24KHz (high quality stereo music)。
Reliability at carrier level
HUAWEI offers high reliability UC solutions，The reliability of HUAWEI UC can reach 99.999%，Reflected in the following aspects：
- Telecom platform based on ATCA；Redundant deployment of equipment critical components；
- Support geographic disaster tolerant network；
- SBC supports geographic disaster tolerance in different location and hot standby mode，The backup system can backup the user's signing data in real time、Registration status、Service data；
- The main standby system represents only one IP address to the terminal；
- System switching does not require terminal re registration。
Unique intelligent flow control patent technology，Easy to withstand 64 times the volume of big bang：64Times the big traffic impact without downtime，10Double overload can guarantee the success rate of 80% business，Easy to resist the network storm。
End to end capabilities open
Different enterprises have different business habits，HUAWEI's IMS business platform supports the ability to open communications to businesses with customized communications capabilities。The network side can be opened to enterprise applications through the API business open interface。At the terminal side，Through the software SDK way to communicate ability to open downward，Integrating communication capabilities into a terminal device。
