The embodiments of the disclosure provide a method and gateway for communication between a browser and a telecommunication network. The method is applied to the gateway, and includes that: a first link with the browser is established, and a second link with a NGN or IMS network is established; first data from the browser is received on the first link, the first data is converted to obtain second data when the first data is call related Session Initiation Protocol (SIP) signaling, and the second data is sent to the NGN or IMS network on the second link; and third data from the NGN or IMS network is received on the second link, and when the third data is call related SIP signaling, and fourth data obtained by converting the third data is transparently transmitted to the browser on the first link. Fusion of an Internet technology and a communication technology is implemented.
