China Unicom Global (CUG) has signed an IPX direct interconnection bilateral agreement with regional peers PCCW Global, Hutchison Global Communications (HGC) and Chunghwa Telecom.
The direct IPX peering agreement will allow CUG to expand its mobile roaming coverage areas.
In a statement, CUG said the agreement will also help provide mobile customers within the region reached by its new partners with high quality mobile voice and data roaming services as well as advanced IP services including VoLTE and HD video calling.
CUG executive vice president Yuerui Ma said CUG IPX will become a critical platform for the operator's international roaming data exchange.
He said CUG aims to jointly promote direct-connection among mobile networks in Asia-Pacific by using IPX direct-connection. This would allow operators in the region to provide faster, stabler and more secure international roaming services for mobile customers.
CUG, China Unicom's wholly-owned international subsidiary, has a presence in 28 branches worldwide. Its main businesses include leased line, internet, system integration, cloud computing, data center, video conferencing and MVNE services.
