System and method for adaptive deep-sleep slotted operation
First Claim
1. In a wireless communication network, a method for adaptively modifying the sleep-mode behavior of a mobile station, wherein the wireless communications network includes control communications and a base station to transmit broadcast messages monitored by the mobile station, the method comprising:
- maintaining a record of traffic communications to the mobile station by making a record of traffic communications to the mobile station over a period of time greater than a day;
determining cyclic patterns of traffic communication activity, in response to the traffic communications record by determining daily patterns of traffic communication activity; and
reducing control communications with the wireless communications network during periods determined to have low traffic communication activity, wherein the control communications between the base station and the mobile station include a slotted mode of operation where the mobile station monitors broadcast messages transmitted at a first periodic rate and, after control communications have been reduced, the mobile station monitors broadcast messages transmitted at a second periodic rate, slower than the first rate.

Abstract
A system and method have been provided that permit a mobile station to enter a deep-sleep slotted mode of operation in response to detected patterns of low traffic communications. A record of traffic communications is maintained at either the mobile station, or in the wireless communications network. Analysis of the record indicates whether the mobile station should be operated in the deep-sleep mode. Then, the deep-sleep mode, with a larger period between control messages, is negotiated. In some aspects of the invention, the period between control messages is a function of the likelihood of a traffic communication occurring.

12. In a wireless communication networks, a method for adaptively modifying the sleep-mode behavior of a mobile station, wherein the wireless communications network includes a base station to transmit broadcast messages monitored by the mobile station, the method comprising:
-
maintaining a record of traffic communications to a mobile station; determining cyclic patterns of traffic communication activity, in response to the traffic communications record; reducing control communications with the wireless communications network during periods determined to have low traffic communication activity, initiating a mobile station traffic communication; supplying a warning from the base station message service that the initiation of the traffic communication with the mobile station will be delayed.

13. In a wireless communications network, a system for adaptively modifying the sleep-mode behavior of a mobile station, the system comprising:
-
a mobile station having a wireless communications port to communicate traffic and control communications with the wireless communications network; an interacting memory, microprocessor, and software application of machine executable instructions to maintain a record of mobile station traffic communications and, in response to the traffic communications record, determining cyclic patterns of traffic communication activity, wherein control communications are reduced between the mobile station and the wireless communications network during periods determined to have low traffic communication activity; and a base station to transmit broadcast messages monitored by the mobile station, the base station decreasing the frequency of transmitted broadcast messages when control communications between the wireless communications network and the mobile station are reduced. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
