Abstract: Example embodiments of the present disclosure relate to switching over without disconnection of access network. In an example method, a core network device receives a sensing request from a terminal device. The first apparatus receives an internal indication of the switchover from a second apparatus of the terminal device separable from the first apparatus; switches from a first context associated with the first traffic to a second context associated with the second traffic; and sends a response to the second apparatus of the terminal device to indicate that the switching is completed. In this way, the first apparatus of the terminal device can switch from the first context to the second context, without disconnection with the access network, and without interrupt of the service.

Abstract: Various example embodiments relate to authentication in case of roaming. An apparatus may be configured to receive, by an application function of a first visitor public land mobile area network (PLMN) or a second visitor PLMN of a device, a registered serving network identifier of the device indicative of the first visitor PLMN; and transmit, based on the registered serving network identifier, an encryption key to an application security function of the first visitor PLMN for encryption of an application session of the device.

Abstract: A technique comprising: sending to a proxy function from a client function a first service request for which the client function delegates to the proxy function discovery, via a network repository function, of a service producer for the first service request; receiving at the client function in reply to the service request a service response, wherein the service response includes an authorisation token indicating a token scope; and in response to a determination that the indicated token scope at least partly matches a requested scope for a second service request regardless of whether the token scope fully matches the requested scope, including the authorisation token in the second service request.
