Abstract: A method and system enables a packet-switched data communication in a wireless communications system to be quickly and easily reestablished after interruption. The computer communications protocol that has been negotiated during the establishment of the packet-switched data communication may be saved upon interruption and later restored. In an exemplary embodiment, a wireless subscriber activates a call-waiting-type service along with an option to retain a packet-switched data communication. Thereafter, the subscriber may be engaged in a data communication on a packet data channel of the wireless communications system. Acceptance of a subsequent incoming, circuit-switched voice call causes the data packet session to be suspended, but the negotiated parameters of the computer communications protocol are saved. After the subscriber terminates the voice call, another data packet session is established with the saved parameters without needing to renegotiate the computer communications protocol parameters.
