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 for chunk based lot service inspection is provided. The method is implemented by a network device in a communication network. Data of IoT service may be received. The data may include a plurality of packets from a network node. The plurality of packets may be shaped into one or more chunks based on packet header information of each packet. Each chunk may include one or more packets. One or more characteristic parameters for each of the one or more chunks may be generated based on one or more properties of the one or more packets in said chunk. A cluster label may be identified for each chunk based on shaping the plurality of packets into one or more the one or more characteristic parameters of said chunk.

Abstract: A system, method, node, user equipment and computer program for establishment of a secure connection between a user equipment (100) and a media gateway (130) at setup of a communication session with another party (150) is described. The media gateway (130) is controlled by a control server (120). The control server (120) receives a communication session setup request from the user equipment (100) and determines an indication of a security certificate of the media gateway (130). The control server (120) then sends the indication of the security certificate of the media gateway (130) to the user equipment (100), wherein the indication is sent before or in parallel to sending the communication session setup request towards said other party (150). The user equipment (100) then initiates a negotiation of security related parameters, based on the received indication of the security certificate of the media gateway (130).

Abstract: A method of establishing a secure connection between a user equipment, UE, and a media gateway, MGw, at setup of a communication session between the UE and another party. The MGw is controlled by a control server and the setup of the communication session comprises a security handshake procedure. The method comprising, prior to receiving a communication session set-up request, determining by the control server whether the MGw supports a procedure for early commencement of the security handshake and providing by the UE to the control server an indication that the UE supports the procedure for early commencement of the security handshake procedure and connection parameters for use in the security handshake. On receiving, by the control server, a communication session setup request from the other party, if both the UE and the MGw support the procedure for early commencement of the security handshake procedure, an instruction is sent to the Media gateway to commence the security handshake procedure.

Abstract: Embodiments of the present disclosure provide a method for scaling of a server VNF Manager VNF in a virtualized network. The virtualized network comprises at least a server VNF, a client VNF connected to the server VNF and a VNF manager. The connection between the client VNF and the server VNF is initiated by the client VNF. The method is performed at a PCM server. Firstly, scaling information is obtained at the PCM server in response to a scaling operation performed by the VNF manager on the server VNF. Once the scaling information is obtained, then the PCM server notifies the client VNF of the scaling information. There is also provided a method performed at a client VNF and corresponding apparatuses.
