A system of a telecommunications network that uses IP Multimedia Subsystem (IMS) network elements to screen inbound calls. A Media Resource Function (MRF) intercepts an inbound call and uses various techniques to screen the call. The MRF redirects the call to an interactive voice response (IVR) system, which prompts the caller to state the caller's name, records the caller's response, and relays it to the called subscriber, who can then decide to accept or reject the call. The system can present a random number challenge to the caller. The system can use machine learning analytics and a large language model (LLM) to analyze the response's contents, accepting the call only if it relates to a topic allowed by the subscriber, perform audio analysis to determine whether the caller sounds robotic, or detect whether the response contains other known robocall markers.

The invention relates to the field of new-generation information systems, and discloses an operating system adaptation method for accessing an IMS system terminal, which comprises the following steps of: acquiring network state information and hardware resource state information of the IMS system terminal, constructing a game model of bandwidth resource allocation on the basis of the network state information and the hardware resource state information, and determining a video transmission strategy adapted to a WebRTC communication application; and on the basis of the obtained video transmission strategy, further combining with the hardware resource state information to establish a multi-resource constraint optimization model, and calculating a hardware resource optimal allocation scheme in a terminal operating system for supporting the implementation of the video transmission strategy. By adopting a cross-layer state sensing and scheduling cooperation mechanism, the technical effects of multi-level information synchronization and dynamic scheduling in the video transmission process are achieved. Compared with a scheme of performing strategy adjustment only based on single-layer network feedback in the prior art, the problems of low response speed and single adaptive scene are solved.

A system of a telecommunications network that blocks spoofed calls. The system includes an interconnect session border controller (I-SBC) that can receive an inbound call over a network interface. The inbound call is associated with an identifier (e.g., a Session Initiation Protocol (SIP) identifier). The I-SBC causes a Spoofed Call Identification Function (SCIF) to compare the SIP identifier of the inbound call against a list of allowable SIP identifiers. In one example, the I-SBC receives an indication from the SCIF that the SIP identifier of the inbound call does not match any identifier on the list of allowable SIP identifiers. As such, the system rejects the inbound call as an illegitimate call. The illegitimate call is not forwarded to an IP Multimedia Subsystem (IMS) of the telecommunications network.
