Telstra is the first carrier worldwide to operate a combined core network for its 2G, 3G and 4G traffic. The triple-access Evolved Packet Core is now in commercial service, enabling seamless handover of 2G, 3G and 4G traffic.
Ericsson supplied the Evolved Packet Core (EPC) that enables the mobile broadband traffic carried in Telstra GSM, WCDMA/HSPA and LTE access networks to be seamlessly handled by the same core network nodes.
Mike Wright, Telstra’s Executive Director of Network and Access Technologies, says: “Through implementing the Evolved Packet Core, we can smoothly integrate and transition 2G, 3G and 4G traffic seamlessly for our customers. This is the complete network solution that we envisioned over 5 years ago: a common and efficient core network supporting traffic from any source across our evolving GSM, WCDMA and LTE access networks.
Ericsson noted that it has signed 30 commercial EPC contracts to date.
