US 2022/0046652 A1 · SYSTEMS AND METHODS FOR RADIO ACCESS NETWORK-LEVEL ALLOCATION AND RETENTION PRIORITY BASED ON NETWORK SLICING

Abstract

A system described herein may provide a technique for allocation and/or preemption of radio access network (“RAN”) resources in a wireless network based on Quality of Service (“QoS”)-related metrics associated with User Equipment (“UEs”) that are connected to, and/or are requesting connection to, a RAN. QoS-related metrics may include a network slice, a QoS Flow Identifier (“QFI”), other suitable metrics. A Slice-Based Priority (“SBP”) determine one or more priority (e.g., SBP) values for UEs connected to the one or more RANs, and/or for UEs requesting connection to such RANs. In addition to QoS-related metrics priority values may be determined based on RAN-related metrics, such as Allocation and Retention Priority (“ARP”) values associated with a UE. RANs may accordingly be able to allocate resources, accept or deny connection requests, and/or perform preemption based at least partly on slice-related QoS metrics, thus preserving end-to-end QoS parameters.

Dependent claims

A device, comprising:

one or more processors configured to:
receive a request for a priority value associated with a particular Quality of Service (“QoS”) flow associated with a User Equipment (“UE”), the particular QoS flow further being associated with a particular network slice out of a plurality of network slices associated with a core of a wireless network, the request including an identifier of the particular network slice;
determine the priority value based on the identifier of the particular network slice;
and
output the priority value to a base station associated with a radio access network (“RAN”) of the wireless network, wherein the base station uses the priority value to determine an allocation of resources of the RAN to the particular QoS flow.

2 more elements

A non-transitory computer-readable medium, storing a plurality of processor-executable instructions to:

receive a request for a priority value associated with a particular Quality of Service (“QoS”) flow associated with a User Equipment (“UE”), the particular QoS flow further being associated with a particular network slice out of a plurality of network slices associated with a core of a wireless network, the request including an identifier of the particular network slice;
determine the priority value based on the identifier of the particular network slice;
and
output the priority value to a base station associated with a radio access network (“RAN”) of the wireless network, wherein the base station uses the priority value to determine an allocation of resources of the RAN to the particular QoS flow.
