Abstract: A session border controller (SBC) system includes an SBC signaling and media processing module and an SBC signaling access module. The SBC signaling access module is configured to: receive signaling sent by a terminal and forward the signaling to the SBC signaling and media processing module; and when the terminal is disconnected from a network during a call, re-register and reconnect the terminal, and after the terminal is reconnected, receive an information request from the terminal during the call and forward the information request to the SBC signaling and media processing module. The SBC signaling and media processing module is configured to: process the signaling and media streams from the terminal, and when the terminal is disconnected from the network during the call, learn, based on the information request, a transmission link for communication with the terminal after the terminal is reconnected upon the disconnection from the network.

Abstract: A hybrid chip-on-heatsink device comprises at least one LED die, at least one printed circuit board (PCB), and a thermally conductive substrate or heatsink. The LED die is physically and thermally coupled to the thermally conductive substrate. The PCB is physically coupled to the thermally conductive substrate. The LED die is electrically coupled to the PCB. The thermally conductive substrate acts as a spreader and as a heatsink, whereby heat is efficiently dissipated away from the LED die. The PCB may optionally contain other electrical components, and circuitry to create a “smart” LED package or light engine.
