## Abstract

A disclosed method may include (i) receiving a message including first buffering-relevant information relating to an ability of a specific centralized unit-user plane node to perform a buffering procedure, (ii) evaluating the first buffering-relevant information against second buffering-relevant information indicating at least in part whether an item of user equipment is an appropriate candidate for the buffering procedure, and (iii) assigning the specific centralized unit-user plane node based at least in part on evaluating the first buffering-relevant information against the second buffering-relevant information. Related systems and computer-readable mediums are further disclosed.

## Claims

### Claim 1
