Abstract
When using Dual Connectivity in a Non-Standalone Architecture cellular communication system, a data bearer may be steered through a Long-Term Evolution (LTE) base station or a New Radio (NR) base station. Each bearer is assigned a combination of Quality of Service (QoS) values corresponding to the service type that the bearer is supporting. For example, each different service type may be assigned a combination of a QoS Class Identifier and an Allocation and Retention Priority parameter value. Each combination is also associated with a radio access technology such as LTE radio access technology or NR radio access technology. When NR communications are available between a network core and a communication device, and if the bearer's combination of QoS values has been associated with NR, bearer data is routed through an NR base station. Otherwise, the bearer data is routed through the LTE base station.
