A technique of triggering transition control between different RRC states of wireless terminal devices is described. A method aspect of this technique comprises receiving a request for an RRC state transition control for a terminal device, wherein the request includes at least one identifier associated with the terminal device. The method further comprises obtaining a temporal inactivity parameter associated with the at least one identifier, wherein the temporal inactivity parameter depends on an estimated period of time between two traffic activities of the terminal device. Further still, the method comprises triggering, based on the temporal inactivity parameter or a parameter derived on the basis of the temporal inactivity parameter, the RRC state transition control for the terminal device.

Transition control between radio resource control states

A computer-implemented method, performed by a first node (), for verifying a second node () as a server for an application. The first node () obtains (), from a third node (), a first request to verify a first Internet Protocol (IP) address for a first domain for the application. The first request indicates the first domain and the first IP address. The first node () sends () a first connection request to the second node () using the first IP address. The first connection request comprises the first domain indicated in the first request. The first node () receives (), in response to the sent first connection request, an indication from the second node (). The indication comprises a certificate of the second node (). The first node () also sends () a message to the third node () based on a result of the validation and authentication.

A data traffic routing method and apparatus for controlling data traffic in a communication network, the method comprising: receiving, at a first agent from a User Plane Function, communication network status information; calculating, by the first agent, data traffic routing instructions using a current routing model; sending by the first agent: the data traffic routing instructions to the User Plane Function; and experience information to a second agent; storing, at the second agent, the experience information; determining, at the second agent, if the number of instances of stored experience information exceeds a predetermined threshold; and if it is determined that the number of instances of stored experience information exceeds a predetermined threshold: training a neural network using the instances of stored experience information; and updating the current routing model using results of the neural network training.

Embodiments of the disclosed techniques include methods for estimating network performance of a path between a terminal device and an application server through a core network. In one embodiment, the method comprises measuring network performance of a portion of the path within the core network to obtain one or more partial network performance measurements in a first period, obtaining one or more end-to-end measurements of the path in the first period, where the end-to-end measurements are values of an end-to-end performance indicator; and estimating one or more values of the end-to-end performance indicator in a second period after the first period, using partial network performance measurements in the second period and the machine learning function.
