Method for scheduling packet data transmission
First Claim
1. A method comprising:
- receiving a broadcast control message that specifies a plurality of mobile stations for packet data services;
determining that a mobile station is not specified in the broadcast control message; and
the mobile station that is not specified entering a low power mode in response to the determining,wherein the mobile station determines that it is not specified by evaluating a value in a designated activity field of the broadcast control message that is associated with a temporary identifier, the temporary identifier being assigned to the mobile station that is not specified.

Abstract
In a packet data transmission and reception system, a media access control (MAC) message is broadcast by a base station to a plurality of mobile stations. The MAC message contains packet data transmission scheduling information which allows the base station to preemptively control mobile station access to traffic channels in order to maximize the efficiency of packet data transmissions and allow scheduling consideration including priority access, quality of service and maximum bytes per transfer. The MAC message consists of a control frame structure, which comprises scheduling parameters including MAC IDs fields, activity fields, and a field representing the number of free traffic channels in a cell. These parameters enable multiple mobile stations to share, in a time multiplexed fashion, traffic channels for packet data transmission on CDMA based mobile communication systems.

11. A memory storing a program for controlling operation of a controller to effect a power saving mode by actions that comprise:
-
determining that a mobile station is not specified in a received broadcast control message that specifies a plurality of mobile stations for packet data services; and responsive to the determining, placing the mobile station that is not specified in a low power mode; wherein the determining that a mobile station is not specified in the broadcast control message comprises evaluating a value in a designated activity field of the broadcast control message, the designated activity field associated with a temporary identifier that is assigned to the mobile station that is not specified. - View Dependent Claims (12, 13, 14, 15, 16)
