Abstract
Methods and apparatus, including computer program products, are provided for ping pong detection. In some example embodiments, there may be provided a method that includes subscribing to an event at one or more access and mobility management functions, the event indicative of a frequent mobility of a user equipment between different access and mobility management functions; and receiving, from an access and mobility management function, a notification of the subscribed event. Related systems, methods, and articles of manufacture are also described.

1-47. (canceled)
A method performed by a network data analytics function of a core network, the method comprising:
- subscribing to an access and mobility function of the core network to be notified about an event indicative of mobility of a user equipment to a second access and mobility management function while the user equipment has been served by the access and mobility function for a short duration less than a threshold duration;
- and
- receiving, from the access and mobility management function, a notification of the event.
A method comprising:
- receiving, at a first access and mobility function of a core network, a subscribe message to be notified of an event indicative of mobility of a user equipment to a second access and mobility management function while the user equipment has been served by the first access and mobility function for a short duration less than a threshold duration;
- and
- detecting, by the first access and mobility management function, the event;
- and
- sending, by the first access and mobility management function, a notification of the event.
A method comprising:
- receiving, at a first access and mobility function of a core network, a subscribe message to be notified of a ping pong event indicative of a ping pong by a user equipment between a second access and mobility management function and the first access and mobility function;
- and
- detecting, by the first access and mobility management function, a threshold number of mobility events within a threshold period of time, wherein each mobility event of the plurality of mobility events is indicative of mobility the user equipment to the second access and mobility management function while the user equipment has been served by the access and mobility function for a short duration less than a threshold duration;
- and
- sending, by the first access and mobility management function, a notification ping pong event.
