Abstract
The present invention provides methods and apparatus for notifying Quality of Service (QoS) information to User Equipment (UE), Users, and Application server. Embodiments of the present invention may analyze the network QoS and/or statistics of QoS parameters using one or more functions such as Network Data Analytics Function (NWDAF). Embodiments may also provide control plane (CP) functions which may send the QoS information to the UE depending on the UE subscription, application and/or network slice.
Claims16
A method comprising:
- receiving, by a network data analytics function (NWDAF), a message from an application function (AF) through a network exposure function (NEF), wherein the message is indicative of a request or a subscription of the AF to data analytics information associated with network quality of service (QOS) information of one or more user equipment (UE), wherein the message includes:
- UE location of the one or more UE, a start time and an end time indicating a time duration for which the network QoS information of the one or more UE is applicable, a QoS level, and threshold value(s) of QOS parameters in the QOS level wherein the threshold value(s) of the QoS parameters is associated with a condition to trigger the data analytics;
- collecting, by the NWDAF, network data for producing the data analytics information;
- obtaining the data analytics information, by the NWDAF, by performing data analytics using information in the message and the network data, wherein the data analytics information indicates a threshold value which is met or exceeded, a location at which the threshold value is met or exceeded and a time period during which the threshold value is met or exceeded;
- sending, by the NWDAF to the AF through the NEF, the data analytics information in response to the message, wherein the data analytics information is used for an adjustment in operation of the one or more UE based on the data analytics information.
2 more elements
A network data analytics function (NWDAF), comprising:
- at least one processor and a non-transitory computer readable storage medium including instructions to be performed by the at least one processor to configure the NWDAF to:
- receive a message from an application function (AF) through a network exposure function (NEF), wherein the message is indicative of a request or a subscription of the AF to data analytics information associated with network quality of service (QOS) information of one or more user equipment (UE), wherein the message includes:
- UE location of the one or more UE, a start time and an end time indicating a time duration for which the network QoS information of the one or more UE is applicable, a QoS level, and threshold value(s) of QoS parameters in the QoS level wherein the threshold value(s) of the QoS parameters is associated with a condition to trigger the data analytics;
- collect network data for producing the data analytics information;
- obtain the data analytics information by performing data analytics using information in the message and the network data, wherein the data analytics information indicates a threshold value which is met or exceeded, a location at which the threshold value is met or exceeded and a time period during which the threshold value is met or exceeded;
- send to the AF through the NEF, the data analytics information in response to the message, wherein the data analytics information is used for an adjustment in operation of the one or more UE based on the data analytics information.
