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.
Claims19
A method comprising:
- sending, by an access network (AN) node to an access and mobility management function (AMF), a message indicating which QoS parameter could not be supported, wherein the message further includes at least one value for a QoS parameter which could be supported;
- and
- forwarding the message by the AMF to a session management function (SMF).
A communication system comprising an access network (AN) node and an access and mobility management function (AMF), wherein
- the AN node is configured to:
- send to the AMF a message indicating which QoS parameter could not be supported, wherein the message further includes at least one value for a QoS parameter which could be supported;
- and
- the AMF is configured to:
- forward the message to a session management function (SMF).
A method for supporting User Equipment (UE) operation in a wireless communication network, the method comprising, by a network data analytics function (NWDAF) or another function operating in the network:
- obtaining travel route information for the UE, the travel route information corresponding to a planned or predicted route to be traversed by a vehicle associated with the UE;
- obtaining QoS requirements for an application operating at least partially on the UE;
- determining whether portions of the route exist for which a determined probability of failing to meet the QoS requirements is at least equal to a predetermined threshold;
- and
- when one or more of said portions of the route exist, transmitting an indication of said one or more portions of the route toward one or more of:
- the UE;
- an application in the network which cooperates with the UE for assisting driving of the vehicle;
- a vehicle-to-everything control function (V2XCF) operating in the network;
- a policy control function (PCF) operating in the network;
- and another function operating in the network.
