TECHNICAL FIELD

The present disclosure is related generally to wireless networks and, more particularly, to methods and a computing device for splitting traffic across multiple accesses.

BACKGROUND

In currently proposed wireless communication schemes, each protocol data unit session is associated with a single access. Thus, for example, a wireless communication device is not permitted to carry out a protocol data unit session on both a first access (such as a fourth generation (“4G”) access) and a second access (such as a fifth generation (“5G”) access). This limits the ability of wireless networks to appropriately allocated bandwidth for different types of communication.

SUMMARY

This document relates to methods, systems, and devices for wireless communication schemes.

In one aspect, a wireless communication method is provided to comprise: receiving, by a first computing device, a notification that a wireless communication device that has previously established a protocol data unit session via a first network access has registered for a second network access; and establishing, by the first computing device, one or more quality of service (QoS) flows for the protocol data unit session for the wireless communication device over the second network access by transmitting, to a second computing device, a message that includes information to associate the one or more quality of service (QoS) flows with the second network access, and wherein the first computing device is configured to carry out a session management function and the second computing device is configured to carry out an access and mobility management function.

In another aspect, a wireless communication method is provided to comprise: receiving, by a first computing device, a notification that a wireless communication device that has previously established a protocol data unit session via a first network access has registered for a second network access; modifying, by the first computing device, one or more quality of service (QoS) flows for the protocol data unit session to associate the one or more quality of service (QoS) flows with the second network access by transmitting, to a second computing device, a message that includes information to associate the one or more quality of service (QoS) flows with the second network access, wherein the first computing device is configured to carry out a session management function and the second computing device is configured to carry out an access and mobility management function.

In another aspect, a wireless communication method carried out by a wireless communication device is provided. The method comprises: establishing a protocol data unit session over a first network access; registering for a second network access; receiving quality of service (QoS) information for the second network access via the first network access; and transmitting an uplink data traffic via the second network access using the received quality of service (QoS) information.

The above and other aspects and their implementations are described in greater detail in the drawings, the descriptions, and the claims.
