Scheduling method and system for communication networks; corresponding devices, network and computer program product

摘要

In a method of scheduling transmission services over a high speed packet access communication link such as a HSDPA and/or a HSUPA link a list of queues is created for transmission services to be provided over the link. The queues, which include both Real Time and Non Real Time queues, are allotted respective service priorities based e.g. on a channel quality indicator and/or a Quality of Service indicator to produce an ordered list of queues based on the service priorities. The link resources needed for serving at least one set of queues having higher priorities in the ordered list are estimated and a check is made. If these resources are available, the set of queues having higher priorities in the ordered list are served. If the resources required are not available, at least one queue is removed from the ordered list of queues.

1. A method of scheduling transmission services including the steps of:
creating a list of queues of Real Time and Non Real Time transmission services to be provided over a high speed packet access wireless communication link, allotting to each of said queues of Real Time and Non Real Time transmission services in said list a respective Real Time or Non Real Time service priority, wherein the Real Time service priority is based at least in part on a channel quality indicator and the Non Real Time service priority is based on a metric dictated by an amount of data that a user associated with the respective Non Real Time service queue would be able to send divided by an amount of data in a queue buffer, producing an ordered list of queues of Real Time and Non Real Time transmission services based on the respective allotted Real Time or Non Real Time service priorities, estimating link resources needed for serving at least one set of queues ordered higher in said ordered list of queues, checking whether said link resources are available, and:
i) if said link resources are available, serving said at least one set of queues ordered higher in said ordered list of queues, andii) if said link resources are not available, removing from said ordered list of queues at least one queue from said at least one set of queues ordered higher in said ordered list of queues.
