Method for measuring wireless quality of experience
The end-to-end experience of a wireless customer depends on at least data throughput, data loss, and latency, as well as other characteristics. The user's quality of experience (QoE) can be determined based on applications and measurements taken at the application layer of the user's user equipment (UE) and information at the session level at the UE initiated and configured by an operator at the start of the session. The QoE is an application layer measurement configured by the operator and reported inside the application layer. When a UE is performing an inter-system handover, the QoE measurement configuration of the current session cannot be transferred from the source network to the target network.
1. A method for wireless communication, comprising:
receiving, by a target node from a source node through a core network, quality of experience (QoE) area scope information and QoE configuration information that configures a QoE measurement of a wireless device,
wherein the source node is a next generation Node B (gNB) and the target node is an enhanced Node B (eNB), and the QoE configuration information includes a supporting RAT type list of the configured QoE measurement in a UE context/PDU session setup request message received by the source node from a fifth-generation core network, or
wherein the source node is an eNB and the target node is a gNB, and the QoE configuration information includes a supporting RAT type list of the configured QoE measurement in a UE context/Evolved Radio Access Bearer (E-RAB) setup request message sent by an evolved packet core (EPC); and
determining, by the target node based on received QoE area scope information and QoE configuration information, a continuity of QoE measurements for the wireless device.
2. The method of claim 1 , further comprising:
receiving, by the target node from the EPC, a handover request message requesting preparation of resources at the target node for handover, wherein the resources comprise the QoE area scope information and the QoE configuration information.
3. The method of claim 1 , further comprising:
receiving, by the target node from the fifth-generation core network, a handover request message requesting preparation of resources at the target node for handover, wherein the resources comprise the QoE area scope information and the QoE configuration information.
4. The method of claim 1 , further comprising:
determining to use the received QoE configuration information at the target node in a case that the target node is in an area.
5. The method of claim 1 , further comprising:
transmitting, by the target node to the EPC, a handover acknowledge message notifying the EPC that QoE resources have been successfully set up, wherein the resources comprise QoE configuration information, and an indication that the target node is inside or outside an area.
6. The method of claim 1 , further comprising:
transmitting, by the target node to the fifth-generation core network, a handover acknowledge message notifying the EPC that QoE resources have been successfully set up, wherein the resources comprise QoE configuration information, and an indication that the target node is inside or outside an area.
7. The method of claim 1 , wherein the QoE area scope information includes an inter radio access technology (RAT) area scope defining a measurement area in terms of cells or tracking area/routing area/location area for the QoE measurement.
8. The method of claim 1 , wherein the QoE configuration information comprises at least one RAT related QoE configuration associated with a specific RAT, wherein one configuration includes at least one of the following: a QoE metric of radio network layer measurement configuration, or a measurement triggering configuration to support event-based and time-based QoE measurement triggering.
9. The method of claim 1 , wherein the QoE configuration information comprises allowed one or more measured Slices associated with a configured QoE area scope or allowed one or more measured slices associated to a specific area scope including one or more cells, one or more tracking area/routing area/location area.
10. The method of claim 1 , wherein the QoE configuration information comprises a QoE measurement collection identifier for a session.
11. A method wireless communication, comprising:
transmitting, by a source node to a target node, through a core network, quality of experience (QoE) area scope information and QoE configuration information that configures a QoE measurement of a wireless device,
wherein an operations, administration and management (OAM) function configures a supported radio access technology (RAT) type list of the QoE measurement at the source node.
12. The method of claim 11 , wherein the source node is a next generation Node B (gNB) and the target node is an enhanced Node B (eNB).
13. The method of claim 11 , wherein the source node is an eNB and the target node is a gNB.
14. The method of claim 12 , wherein the source node receives a supporting RAT type list of the configured QoE measurement in a UE context/PDU session setup request message sent by a fifth-generation core network.
15. The method of claim 13 , wherein the source node receives the supporting RAT type list of the configured QoE measurement in a UE context/E-RAB (Evolved Radio Access Bearer) setup request message sent by EPC.
16. The method of claim 12 , further comprising:
transmitting, by the source node to a fifth-generation core network, a handover required message requesting preparation of resources at the target node for handover, wherein the resources comprise the QoE area scope information and the QoE configuration information.
17. The method of claim 13 , further comprising:
transmitting, by the source node to an evolved packet core (EPC), a handover required message requesting preparation of resources at the target node for handover, wherein the resources comprise the QoE area scope information and the QoE configuration information.
18. The method of claim 12 , further comprising:
receiving, by the source node from a fifth-generation core network (5GC), a handover command message notifying the source node that resources for a handover have been prepared at the target node, wherein the resources comprise at least one of:
the QoE configuration information,
an indication that the target node is inside or outside an area for the QoE measurement, or
a QoE deactivation indication to stop the QoE measurement.
