Abstract

A method and system is provided for providing packet data service and circuit switch service during the same session to a mobile station (MS) whose capabilities do not allow such services to be provided thereon by the wireless network according to the its specifications. First, a voice service is provided between the MS and a first client through a switch device, the voice service conforming to a predetermined communication protocol. The MS is then notified about an incoming data service request from a second client to transfer a predetermined amount of data. The voice service is disconnected between the switch device and the MS if the user decides to activate the incoming data service. The voice service between the switch device and the first client is still maintained. The data service from the second client to the MS through the switch device is then established. The data service between the switch device and the MS is disconnected while the data service between the switch and the second client is maintained after the predetermined amount of data has been transferred from the second client to the MS. The voice service between the switch and the MS is re-established if needed. Also, the same client can initiate the voice and packet data service request to the same MS.
