Boost your broadband access by combining xDSL/HFC & 4G/5G
Seamlessly transition between 4G/5G and Wi-Fi for a better user experience
An open source and standardised TCP extension
Enhanced 5G & WiFi seamless mobile connectivity
→ The user disables Wi-Fi, and then remains on cellular sometimes for hours.
Seamless Overlapping Handover enables 4G/5G traffic to transition to/from Wi-Fi without disturbing the user experience.
To achieve this, in 2020 the 3GPP defined the ATSSS feature (Access Traffic Steering Switching & Splitting), based on MPTCP technology, comprising software on the handset and in the network.
MPTCP has been used in Apple handsets since 2013 and Samsung handsets since 2015.
ATSSS is implemented in the OS of the smartphone by the smartphone manufacturer.
ATSSS is deployed via a Hybrid Access Gateway.
Smartphones will soon support ATSSS in the OS (ie. without the need for a 3rd party app). The smartphone ATSSS component is responsible for deciding which network paths to open and when.
The Tessares Overlay ATSSS HAG component is based on our field proven hybrid access gateway. The advantage of Overlay ATSSS is that, whereas 3GPP Rel 16 envisages ATSSS in the UPF of the 5G Core, service providers can deploy Tessares’ Overlay ATSSS today for 4G & 5G while waiting for ATSSS/5GC to be delivered.
