Abstract:
A radio communication terminal that performs data communication by selecting either one of a first data communication protocol and a second data communication protocol that has a lower level of priority than that of the first data communication protocol, comprising: a communication protocol determining part (6c) that determines whether or not a base station that is performing a communication is compatible with the first data communication protocol; a session status determining part (6f) that determines whether or not the establishment of communication session layers that perform the exchanging of the parameters required for communication with the base station has been completed; and a communication control part (6a) that selects either one of the first data communication protocol and the second data communication protocol based on a determination of the communication protocol determining part, and performs data communication on a selected protocol, wherein when the communication control part (6a) begins data communication via a base station which it has been determined is compatible with the first data communication protocol, the communication control part (6a) makes a data communication request using the first data communication protocol if it is determined by the session status determining part that a communication session layer establishment has been completed, the communication control part (6a) defers the data communication request until the completion the communication session layer establishment if it is determined that the establishment has not been completed.
