  • Method and apparatus for dynamically adapting a connection state in a mobile communications system
    Patent number: 6594238
    Abstract: In a mobile communications system that provides packet data services, a packet data connection is established between a mobile station and a radio access network. The state of the connection specifies one of plural different types of radio channels bearing the connection over the radio interface. The connection state preferably also may specify other parameters including for example, one of plural different mobility management schemes tailored to the selected channel type or channel bit rate(s). The connection is dynamically adapted to an optimal state based on one or more conditions relating to the connection. For example, one or more traffic parameters are determined for the connection and used to predict a future value of that parameter. Based on the predicted parameter value or values, an optimal connection state is determined and implemented.
