Abstract: A method for determining sag of an electricity transmission line based on image recognition is provided. In the method, an image of an electricity transmission line in a target area captured by an unmanned aerial vehicle is acquired and coordinates of a catenary corresponding to the electricity transmission line is extracted from the image. A catenary curve equation is constructed based on the extracted coordinates of the catenary and a complete catenary curve is drawn according to the catenary curve equation. A sag expression of the catenary is obtained based on the complete catenary curve and the catenary curve equation. A derivative of the sag expression is calculated to obtain a maximum sag.

Abstract: A method of implementing a Communication Barring, CB, service within an IP Multimedia Subsystem, IMS, network in respect of an ongoing IMS session or an IMS session in early session phase. The method comprises, at an Application Sever, AS, within the IMS network, parsing SIP messages relating to the session to detect an attempt to add one or more media streams to the session. CB service rules are applied to determine the allowability of the media stream(s) being added. If the media stream(s) being added is (are) not allowed, action is taken to prevent its addition, and otherwise allowing the media stream addition to proceed.
