Abstract: Embodiments herein relate to a method performed by a radio node for handling provision of a service to a wireless device in a wireless communication network. The wireless communication network comprises an access network node serving the radio node over a connection. The radio node transmits an indication to the wireless device, which indication indicates type and/or capacity, for the wireless device or the radio node, of the connection between the radio node and the access network node.

Abstract: A method of securing media across an IP Multimedia Subsystem, IMS, network where the media transits via first and second media gateway functions of the IMS network which are controlled by respective first and second media gateway controllers acting as back-to-back Session Initiation Protocol, SIP, user agents. The method comprises sending from the first media gateway controller to the second media gateway controller, or to anode upstream of the second media gateway controller, security information of the first media gateway function, and using the sent information to secure media between the first and second media gateway functions or between the first media gateway function and said upstream node.

Abstract: Embodiments of the present disclosure relate to a method and device for facilitating a connectivity check between a terminal device and a media gateway. In example embodiments, the session controller receives, via a web gateway associated with said terminal device, a request for establishing a real-time communication call and an indication for indicating a capability of said terminal device for early reception of a connectivity parameter of said media gateway to be used in said connectivity check. The session controller obtains said connectivity parameter from said media gateway. Then, in response to said connectivity parameter being obtained, the session controller sends said connectivity parameter via said web gateway towards said terminal device within a time limit. In this way, said terminal device may initiate said connectivity check to said media gateway earlier, and thus a latency of call establishment may be reduced significantly.

Abstract: A method of securely registering a User Equipment, UE, with an IP Multimedia Subsystem, IMS, network. The method comprises sending from the UE to the IMS network, a Session Initiation Protocol, SIP, REGISTER message comprising information encrypted using the public key part of a public-private key pair belonging to the IMS network or to a controller of the IMS network.
