First Claim
1. A method for notifying mobile stations in an inactive state of information transmitted in a frame, comprising the acts of:
- determining whether particular broadcast information will be transmitted in the frame;
determining whether information for at least one of the mobile stations in the inactive state will be transmitted in the frame;
forming an information element notifying mobile stations in the inactive state whether the particular broadcast information or the information for the at least one of the mobile stations in the inactive state will be transmitted in the frame; and
broadcasting the information element in a downlink portion of the frame,whereinthe at least one of the mobile stations in the inactive state is in an idle mode, and the information for the mobile station in the idle mode is information related to a paging message, orthe at least one of the mobile stations in the inactive state is in a sleep mode, and the information for the mobile station in the sleep mode is information related to a traffic channel assignment.

Abstract
Methods and apparatus for notifying mobile stations in an inactive state of the presence of uplink or downlink channel configuration, broadcast system updates, traffic channel allocations and paging messages are provided. The notification can be provided in an information element in the same channel as the frame, or in a different channel. The information element identifies a subsequent frame which includes broadcast or configuration changes. The notifications for traffic channel allocations can include a first field, which identifies whether there are any traffic channel allocations for any sleep mode mobile station, and a second field for identifying the particular sleep mode mobile stations which are to receive traffic channel allocations. Notifications for paging messages can include a field, which identifies whether there are any paging messages for any idle mode mobile stations, and use second field to identify the particular idle mode mobile stations, which are to receive the paging messages.

11. A method for determining whether a frame includes information for a mobile station in an inactive state, comprising the acts of:
-
receiving a frame that includes a plurality of information elements; decoding an information element of the plurality of information elements; examining the information element to determine whether the information element identifies that particular broadcast information is in the frame or will be transmitted in a subsequent frame, and whether the information element identifies that information specific to the mobile station is in the frame, wherein when the information element identifies that the particular broadcast information is in the frame the mobile station decodes the particular broadcast information in the frame, and wherein when the information element identifies that information specific to the mobile station is in the frame the mobile station decodes the information specific to the mobile station in the frame. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for determining whether a frame includes information for a mobile station in an inactive state, comprising the acts of:
-
receiving, by a mobile station in an inactive state, an information element in a downlink portion of the frame; examining a first field of the information element to determine whether the information element includes additional information for at least one of a group of mobile stations in the inactive state; and when it is determined that the information element includes the additional information for the at least one of the group of mobile stations in the inactive state the mobile station examines a second field of the information element to determine whether the information element identifies the mobile station in the inactive state, wherein the second field indicates that a portion of the frame other than the information element includes information for the mobile station. - View Dependent Claims (24, 25, 26, 27, 28)
