Abstract

A method and apparatus for seamless real-time transitions across LTE and Wi-Fi networks are disclosed. The disclosed method and apparatus relate to determining which communications networks to use when communicating between a UE and a network within an Enterprise Network (EN). In some embodiments, a Communications Client Application (CCA) operates within a selected UE and a Communications Server Application (CSA) operates on the network side of the Enterprise Network. Both the CCA and the CSA act together in concert to coordinate the transmission of packets between the UE and the network using either LTE or Wi-Fi networks. For seamless communications, some embodiments use a single VPN tunnel through which to transmit data packets. In other embodiments, for seamless communications, two VPN tunnels are used, one for LTE packet transfers, and one for Wi-Fi packet transfers.

Dependent claims

An apparatus for seamless real-time transitions across LTE and Wi-Fi networks, comprising:

a) a User Equipment (UE) comprising a Communications Client Application (CCA), a single Virtual Private Network (VPN) tunnel, and a plurality of UE Applications;
wherein the CCA routes packets to and from the plurality of UE Applications, and wherein packets requiring seamless communications are routed through the single VPN tunnel;
and wherein the CCA determines whether to transmit or receive packets using Long Term Evolution (LTE)/NR (New Radio) or Wi-Fi;
and wherein UE Applications not requiring seamless communications have their packets routed by the CCA directly using the LTE/NR or the Wi-Fi;
and
b) an enterprise network comprising a Communications Server Application (CSA), the single VPN tunnel included in the UE, a server LTE/NR access point, and a server Wi-Fi access point;
wherein the enterprise network communicates with an Intranet/Internet and is able to receive packets from and send packets to the Intranet/Internet;
wherein the CSA routes Intranet/Internet packets requiring seamless communications through the single VPN tunnel;
and wherein the CSA determines whether to transmit or receive packets using either the server LTE/NR access point or the server Wi-Fi access point;
and wherein Intranet/Internet packets that do not require seamless communications are routed by the CSA directly through either the server LTE/NR access point or server Wi-Fi access point.

An apparatus for seamless real-time transitions across LTE and Wi-Fi networks, comprising:

a) a User Equipment (UE) comprising a Communications Client Application (CCA), an Long Term Evolution (LTE) Virtual Private Network (VPN) tunnel for communications of packets via LTE, a Wi-Fi VPN tunnel for communications of packets via Wi-Fi, and a plurality of UE Applications;
wherein the CCA routes packets to and from the plurality of UE Applications, and wherein packets requiring seamless communications are routed through either the LTE VPN tunnel or the Wi-Fi VPN tunnel;
and wherein the CCA determines whether to transmit or receive packets over LTE/NR or over Wi-Fi;
and wherein UE Applications not requiring seamless communications have their packets routed by the CCA directly through either the LTE/NR or the Wi-Fi;
and
b) an enterprise network comprising a Communications Server Application (CSA), the LTE VPN tunnel and the Wi-Fi VPN tunnel included in the UE;
wherein the enterprise network communicates with an Intranet/Internet and is able to receive packets from and send packets to the Intranet/Internet;
wherein the CSA routes Intranet/Internet packets requiring seamless communications through either the LTE VPN tunnel or the Wi-Fi VPN tunnel;
and wherein the CSA determines whether to transmit or receive packets using either LTE/NR or Wi-Fi;
and wherein Intranet/Internet packets that do not require seamless communications are routed by the CSA directly through either LTE/NR or Wi-Fi.
