HGC IPX Services

A quality-based solution for IP Interconnect

A quality-based solution for IP Interconnect

​HGC-IPX has been developed with reference to specification of GSMA IR34. It is a single private IP network that interconnects fixed and mobile network operators, application service providers and content providers for the provision of multiple services such as data roaming, BlackBerry, voice and video traffic, LTE roaming and mobile signalling.

Leveraging MPLS technology, the highly-secure HGC-IPX service provides QoS for multiple traffic types, allowing operators to categorize their traffic into different classes and prioritize across the IPX network to its roaming and inter-working partner.​
