US 2021/0281983 A1 · SYSTEMS AND METHODS FOR NETWORK SLICE ATTACHMENT AND CONFIGURATION

Abstract

A method for slice attachment and configuration, the method comprises: receiving a service request from a user equipment; selecting a second network node to process the service request; receiving a configuration for a network slice to enable the service requested by the user equipment; identifying a first point of presence to receive user plane information corresponding to the network slice; identifying a second point of presence to receive control plane information corresponding to the network slice; forwarding traffic corresponding to the network slice to a third point of presence; transmitting to the user equipment a handle identifying the user equipment context and the network slice configuration; and transmitting to the user equipment a user equipment configuration corresponding to the network slice.

A method comprising:

transmitting, by a user equipment (UE) to a radio access network (RAN) node, a service request for an association to a network slice, the service request containing a descriptor identifying one of a plurality of network slices;
receiving, by the UE from the RAN node, radio link configuration information comprising a first radio link logical channel between the RAN node and the UE used to convey user plane information associated with the network slice associated with the descriptor and quality of service parameters associated with the first radio link logical channel;
transmitting, by the UE to the RAN node, uplink user plane traffic comprising an uplink user plane protocol data unit associated with the first radio link logical channel so as to forward the uplink user plane protocol data unit to a first uplink point of presence associated with the first radio link logical channel.

An apparatus comprising:

one or more processors;
and
a computer readable storage medium storing software instructions for execution by the one or more processors, the software instructions configured to control the one or more processors to:
transmit, to a radio access network (RAN) node, a service request for an association to a network slice, the service request containing a descriptor identifying one of a plurality of network slices;
receive, from the RAN node, radio link configuration information comprising a first radio link logical channel between the RAN node and the apparatus used to convey user plane information associated with the network slice associated with the descriptor and quality of service parameters associated with the first radio link logical channel;
transmit, to the RAN node, uplink user plane traffic comprising an uplink user plane protocol data unit associated with the first radio link logical channel so as to forward the uplink user plane protocol data unit to a first uplink point of presence associated with the first radio link logical channel.

3 more elements

A computer readable storage medium storing software instructions for execution by one or more processors, the software instructions configured to control the one or more processors to:

transmit, to a radio access network (RAN) node, a service request for an association to a network slice, the service request containing a descriptor identifying one of a plurality of network slices;
receive, from the RAN node, radio link configuration information comprising a first radio link logical channel between the RAN node and the apparatus used to convey user plane information associated with the network slice associated with the descriptor and quality of service parameters associated with the first radio link logical channel;
transmit, to the RAN node, uplink user plane traffic comprising an uplink user plane protocol data unit associated with the first radio link logical channel so as to forward the uplink user plane protocol data unit to a first uplink point of presence associated with the first radio link logical channel.
