1. A method for enabling end-to-end connectivity between a wireless communication network and a wired communication network, the method comprising:
implementing a Virtual Endpoint (VEP) in the wireless communication network, the VEP being realized as one of a virtual listener and a virtual talker based on a role of a wireless device in the wireless communication network:
when the role of the wireless device is a talker, the VEP being configured as a virtual listener to:
set up a time sensitive networking (TSN) stream based at least in part on Quality-of-Service (QOS) settings; and
map user plane packets from a QoS flow of the wireless communication network to the TSN stream; and
when the role of the wireless device is a listener, the VEP being configured as a virtual talker to:
receive a QoS for the TSN stream;
map the received QoS to a QoS flow of the wireless communication network;
implementing in the VEP user and control plane features used in the wired communication network;
mapping data traffic, in the VEP, between the device in the wireless communication network and a device in the wired communication network based on the QoS flow of the wireless communication network; and
performing required actions defined by the user and control plane features used in the wired communication network, the wireless communication network being a 5th generation (5G) network and the wired communication network being a Time Sensitive Networking (TSN) network.
