services.Common calls follow the existing call procedures and standards.One-to-one call can be divided into two types: Synchronous call and forward call. When a user calls one-to-one call, the softswitch switches the call to the application server. The application server obtains user data based on the called Number: Same-vibration or forward call, and the transfer number table. The application server will initiate a call to the same vibration number according to the user settings, or call the n
interconnection problem between manufacturers is solved, the softswitch classification or full-plane routing mode can be gradually introduced.
2.2 Traffic Network Design
Due to the adoption of the Fast IP forwarding technology, the soft-switch route organization is flat and connectionless. QoS and security should be considered in the design of the traffic network. Currently, the IP bearer network is mainly implemented using mpls vpn technology. To achieve communication between TG (relay gateway

). Then, the normal scenes can be automatically correctly exposed. Of course, the AE function of this automatic determination of the exposure parameter is not omnipotent. For scenarios with the inverse rate deviation from the average value, such as snow scenes and night views, this method cannot be used to obtain the correct exposure. Therefore, in the software processing module of sensor, the exposure level setting function is usually provided to forcibly change the judgment standard of Automa
