COMMUNICATIONS BRIDGE FOR CIRCUIT SWITCHED DATA TRANSFER SIMULATION

摘要

A communications bridge (300) for simulating circuit switched call links to user equipment receives data from the user equipment over a serial data interface (328). The communications bridge (300) simulates circuit switched call link responses back to the user equipment so that the user equipment believes that a circuit switched call link has been made. Data is sent through a second interface (336) to a wireless radio or GSM modem.
