ABSTRACT:
An apparatus and method for supporting common channel packet data (CCPD) services in a cdma2000 random access network without using a traffic channel. A CCPD device requests CCPD service from the network by sending an Origination message to the BS with the SDB_DESIRED_ONLY bit set to 1 and the FCH_SUPPORTED bit and DCCH_SUPPORTED bit set to 0. Upon successful authentication of the device, PPP connection setup and Mobile IP Registration are performed using SDBs over common channels to exchange messages. The first SDB sent to the CCPD device by the BS acknowledges the device's request for CCPD service. If the BS is unable to support the CCPD service request, no SDB will be sent and the call attempt will fail. A CCPD MS may request CCPD service from the network by sending an Origination message to the BS with the SDB_DESIRED_ONLY bit, FCH_SUPPORTED bit and DCCH_SUPPORTED bit set to 1. If the BS denies the request for CCPD services, normal packet data procedures are performed.
