Abstract
According to certain embodiments, a method by a wireless device is provided for mapping of application data packets onto bearers. The method includes associating at least one tag value with a bearer upon establishment of the bearer. A tag is attached to a packet when passing the packet to a lower layer. The packet is mapped onto the bearer, and a path to transmit the packet is selected.

A method for mapping of application data packets onto bearers, comprising:
- upon establishment of a bearer, associating at least one tag value with the bearer, wherein a Vehicle-to-Anything (V2X) application triggers establishing the bearer, the bearer being a non-IP Evolved Packet System (EPS);
- attaching, at an application layer, a tag to a packet for enabling packet differentiation when passing the packet to a lower layer;
- mapping the packet onto the bearer based on the at least one tag value, wherein the tag is used to decide on which bearer the packet should be mapped;
- and
- selecting which path to transmit the packet, wherein the tag is used for QoS differentiation and enforcement when the packet is transmitted.
A UE comprising a processor and an interface, the processor and the interface coupled to one another, wherein the processor and interface are configured to:
- upon establishment of a bearer, associate at least one tag value with the bearer, wherein a Vehicle-to-Anything (V2X) application triggers establishing the bearer, the bearer being a non-IP Evolved Packet System (EPS);
- attach, at an application layer, a tag to a packet for enabling packet differentiation when passing the packet to a lower layer;
- map the packet onto the bearer based on the at least one tag value, wherein the tag is used to decide on which bearer the packet should be mapped;
- and
- select a path to transmit the packet, wherein the tag is used for QoS differentiation and enforcement when the packet is transmitted.
