METHOD AND APPARATUS FOR SUBSCRIBING CHANGE NOTIFICATION OF NETWORK FUNCTION

A method for subscribing to notification of a change of a network function may comprise: transmitting a subscription message to a monitoring network function; and receiving a notification from the monitoring network function to notify a change from the network function whose status is required to be monitored. The subscription message indicates a type of the network function, and further indicates an attribute of the network function. The attribute comprises a serving scope indicating one or more target served area of the network function whose status is required to be monitored. According to embodiments of the present disclosure, a simple and fast implementation for subscribing notification of change of network function may be achieved. Particularly, both the response time and the accuracy of the notification about a change of a subscribed network function may be improved.
