It provides interfacing of the mobile system to the public switched telephone network. Many users can use their cellular phones simultaneously, and the MTSO has to handle these competing calls. The FIFO policy is not always fair, since more important calls must be served promptly. For example, if there are some voice calls currently in the system—either waiting for connection or already connected—any emergency call must have a priority over them. In addition, any voice call must have a priority over data calls. 1 Since this sheet is educational at a very introductory level, we will consider an over-simplified simulation for the prioritization system mentioned above.
