Abstract
A base station and a router are interactively connected by a multilink group which transmits VoIP packets and a multilink group which transmits data packets other than VoIP packets. The base station and the router split transmission lines by referencing the ToS area of received packets and transmit only VoIP packets by way of a dedicated line. In this way, VoIP packets can be transmitted without being affected by other data packets, and the quality of VoIP can be warranted on the mobile network.
