1. A wireless code division multiple access (CDMA) device comprising:
- a processing device, while in an idle mode, configured, on a condition that payload data associated with a channel is present, to determine a size of the payload data associated with the channel;
wherein the processing device is further configured, on the condition that the payload data associated with the channel is present, to transmit, in an active mode, information to a base station to request traffic channels from the base station;
wherein the processing device is further configured to receive a grant in response to the transmitted information;
wherein the processing device is further configured in response to the grant to transmit the payload data over at least one CDMA channel;
the processing device further configured to transmit a release message after the payload data is transmitted and to return the CDMA device to the idle mode, wherein a mode for device operation over in a forward direction is independent of a mode for device operation in a reverse direction.

Abstract
Data is accessed from a network via a wireless communication link. A determination is made as to whether payload data has been received from a subscriber'"'"'s terminal. If so, then a request is sent for a first set of traffic channels, and the payload data is transmitted over the first set of traffic channels.

9. A method implemented in a wireless code division multiple access (CDMA) device, the method comprising:
-
on a condition that payload data associated with a channel is present when in an idle mode, determining a size of the payload data associated with the channel; on the condition that the payload data associated with the channel is present, transmitting information to a base station to request traffic channels from the base station; receiving a grant in response to the transmitted information; wherein the processing device is further configured in response to the grant transmitting the payload data, in an active mode, over at least one CDMA channel in response to the grant, the CDMA device further configured to transmit a release message after the payload data is transmitted and to return the CDMA device to the idle mode, wherein a mode for device operation over in a forward direction is independent of a mode for device operation in a reverse direction. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
