China Mobile Hong Kong (CMHK) and Huawei announced they have successfully migrated CMHK services to an NFV-based cloud core network for commercial use.
CMHK says all service indicators met expectations following the migration earlier in the month.
CMHK director and chief executive officer Sean Lee said it took two professional teams from CMHK and Huawei “only half a year” to complete the preparation work for the migration and activation for commercial use.
“The synergy between CMHK and Huawei is expected to ensure our entire cloud networks will be smoothly put into commercial use, bringing better service to our customers,” he said.
Wang Yongde, VP of Huawei’s cloud core network product line, explained that on CMHK’s cloud network, “network elements in IMS, packet switched and circuit switched domains are co-deployed. VoLTE, VoWiFi (Voice Over WiFi) and mobile data services are co-operated.”
Wang added that CMHK and Huawei “are jointly developing new technologies, such as network slicing and edge computing to lead the transformation to cloud networks.”
CMHK’s NFV-based cloud core network supports more than 20 network systems, including IMS, evolved packet core, diameter routing agent/ mobile number portability, home subscriber server/ home location register and mobile switching center-server. This network architecture not only helps maximize return on investment and improve operation and maintenance efficiency, but also paves the way to 5G.
CMHK claims to be the first mobile operator to “cloudify” its core network in Hong Kong.
Huawei said it had more than 130 contracts in place worldwide at the end of 2016 to build NFV networks for commercial use.
