Sleep mode control for real-time services in broadband wireless access communication systems

At least one non-transitory computer-readable medium containing a computer program product for controlling sleep modes used with broadband wireless access communication system's real-time services, the computer program product comprising:

• program code for establishing wireless service between a base station and a mobile station wherein the base station and the mobile station set a maximum latency value required while running each real-time service;
• program code for receiving at the base station a sleep request from the mobile station to enter into a sleep mode wherein the sleep request identifies sleep parameters;
• program code for sending from the base station to the mobile station a sleep response selecting sleep parameters wherein sleep parameters include a start frame number for a sleep interval and a power savings class;
• program code for initiating the sleep interval at the mobile station at the start frame number wherein the sleep interval is set according to the power savings class and according to the maximum latency value for each real-time service;
• program code responsive to the completion of the sleep interval, for initiating a listening interval at the mobile station according to the power savings class;
• program code for synchronizing the listening interval of the power savings class with mobile station packet transmissions;
• and
• program code responsive to the base station transmitting to the mobile station during the listening interval at the mobile station, for terminating the sleep mode and resuming normal operations.

A computer system for controlling sleep modes in real-time broadband wireless access communication system services, the computer system comprising:

• a processor;
• a software portion configured to establish real-time wireless service between a base station and a mobile station wherein the base station and the mobile station set a maximum latency value required while running each real-time service;
• a software portion configured to initiate a sleep interval at the mobile station at a start frame number wherein the sleep interval is set according to a power savings class and according to a maximum latency value for each real-time service;
• a software portion configured to synchronize a listening interval of the power savings class with mobile station packet transmissions;
• and
• a software portion configured to resume normal operations responsive to the base station transmitting to the mobile station during the listening interval.
