Abstract
A dynamic quality of service maintenance system for use with a broadband wireless or cable access system comprising a plurality of wireless modems and a wireless hub, the dynamic quality of service maintenance system maintaining adequate bandwidth for the wireless modems based upon the services provided to the wireless modems by the broadband wireless access system.
Claims23
A dynamic quality of service maintenance system for use in a broadband wireless access system comprising a plurality of wireless modems and a wireless hub, the scheduler maintaining adequate bandwidth for the wireless modems based upon the services provided to the wireless modems by the broad band wireless access system, comprising a map scheduler;
- local scheduler;
- global Scheduler;
- admission decision maker;
- and policy and statistics manager.
A wireless communication system, comprising:
- a wireless hub configured to send downstream communications on at least one downstream channel and receive upstream communications from at least one client device on at least one upstream channel;
- wherein said wireless hub comprises,
- a timeline, having timed storage allocations for scheduled services to be provided in conjunction with at least one client device that is communicating with said wireless hub;
- a scheduling mechanism configured to,
- receive service requests from said client devices,
- determine available time for provision of the requested service, and
- place a marker identifying the requesting client and the service to be provided in a timed storage location of said timeline corresponding to the available time;
- and
- a map scheduler configured to retrieve markers in a time window of said timeline and build a MAP message that describes time interval allocation on an upstream channel for said time window.
A method of service scheduling of an upstream channel in a point to multi-point communication system, wherein said point is a hub device, and said multi-point is a set of client devices communicating with said hub, comprising the steps of:
- scheduling said services in a timeline so as to identify a client device;
- building a MAP message comprising at least a portion of the services scheduled in said timeline;
- and
- communicating said timeline to said client devices.
A device for determining time grants for at least one shared communication line, comprising:
- means for storing time grants;
- means for placing periodic time allocations in said storing means for services admitted to devices using said shared communication line;
- and
- means for placing bandwidth requests into said storing means for bandwidth requested by said devices;
- means for building a message indicating which clients may access said at least one shared communication line during specified time intervals;
- and
- means for communicating said message to said clients.
