US 2022/0104296 A1 · METHODS AND DEVICES FOR ESTABLISHMENT OF REDUNDANT PDU SESSION

Abstract

A network function configured for operation in a mobile telecommunications network is provided. The network function is configured to obtain from a User Equipment (UE), a Protocol Data Unit, PDU, session request for establishment of a redundant PDU session and to determine said redundant PDU session to be established based on at least one network condition. The network function is configured to provide the UE the outcome of the determination if said redundant PDU session is to be established. Hereby a network function that can consider Network conditions to determine (initiate/reject) the redundant user plane feature for the URLLC services can be provided. By allowing the network to determine establishment of redundant user plane resource exhaustion can be avoided in that the UE is no longer controlling the establishment of a redundant user plane.

Dependent claims

A network function configured for operation in a mobile telecommunications network, the network function being configured to:

obtain from a User Equipment (UE) a Protocol Data Unit (PDU) session request for establishment of a redundant PDU session;
determine whether the redundant PDU session is to be established based on at least one network condition, wherein the at least one network condition comprises one or more of:
a threshold of network load,
a threshold of network function load,
a threshold of network function service load,
a threshold of network function performance,
a threshold of network function Quality of Service (QoS) support, or
a threshold of network QoS support;
and
provide the UE of the outcome of the determination if the redundant PDU session is to be established.

A non-transitory computer readable-medium storing instructions for performing a method in a network function configured for operation in a mobile telecommunications network, the instructions, when executed by a computer, configure the computer to perform the method comprising:

obtaining, from a User Equipment (UE) a Protocol Data Unit (PDU) session request for establishment of a redundant PDU session;
determining the redundant PDU session to be established based on at least one network condition, wherein the at least one network condition comprises one or more of:
a threshold of network load,
a threshold of network function load,
a threshold of network function service load,
a threshold of network function performance,
a threshold of network function QoS support, or
a threshold of network QoS support;
and
providing the UE of the outcome of the determination if the redundant PDU session is to be established.
