Appl. No.:

10/108405

International Classification:

H04B007/00

US Classification:

370/310000, 370/328000, 370/338000

Abstract:

To address the need for reducing wireless data transfer delay, an embodiment of this invention provides for a radio access network (RAN) () to transmit data, such as a data query, at the time of paging a dormant wireless unit (). By transmitting the data at this time, wireless unit activity in response to the data can begin while the paging and traffic channel setup proceed. Thus, once established, the traffic channel will be idle for less time than under the present practice were data is not sent until the traffic channel setup is completed. Less idle traffic channel time is expected to improve channel utilization and contribute to lower packet data costs.

Abstract:

To address the need for reducing the wireless data transfer delay without reducing channel utilization, an embodiment of this invention provides for a wireless unit (), transitioning from a dormant to an active state, to transmit data, such as a data query, at the time of call origination. The Wireless Network delay and the Data Network delay, ordinarily experienced back-to-back, are instead experienced concurrently. The difference in delay experienced between active versus dormant users is thus nearly eliminated. This will motivate network operators to decrease their inactivity timers, and is thereby likely to improve their channel utilization and reduce the cost of packet data services.
