Method and system for scheduling transmission resources

Abstract

The invention provides a method and system to dispatch the transmission resources, comprising the following steps: Step A. the transmission resources allocated to the business by consulting the generated protection flow and the transmission resources allocated are smaller than or equal to the protection flow; Step B. whether the transmission resources run out or not is determined. Turning to the step E if the transmission resources run out; or continuing to determine whether all the business are visited and turn to step C if all the business are visited; or turning to step A; Step C. Visitingthe business again to supplement the transmission resources needed in the transmission; Step D. Determining whether the transmission resources run out or not, and turning to step E if yes, or continuing to determine whether all the business are visited or not. Turning to step E if yes or turning to step C; Step E. implementing the data transmission after the allocation process is finished. The invention also provides a system to dispatch the transmission resources. The invention allocates the transmission resources according to the actual data transmission demand, which not only avoids the waste of the resources in the fixed or static allocation of the transmission resources, but can also prevent the low transmission efficiency caused by the packet-loss as a result of the transmission data surpassing the allocated bandwidth when a plurality of users transmit the data at the same time.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and system for scheduling transmission resources. Background technique [0002] In the wireless communication network before the second generation, voice service is the most basic and main function of the network. With the development of mobile broadband and broadband mobilization, wireless networks not only carry traditional voice services, but also services such as video calls and web browsing will occupy an increasing proportion. [0003] In the 3rd Generation Partnership Project (3GPP) protocol, four types of services are defined: conversational, that is, real-time conversational services such as voice; streaming, that is, real-time audio, Video streaming services; human-computer interaction services (interactive), that is, interactive services such as web browsing; background services (background), that is, data transmission services between machines. The fir...

[0009] The disadvantage of the above method is that: due to the bursty nature of real-time BE services, it is very likely that multiple users of the same service will transmit data at the same time, and the total amount of instantaneous data will exceed the actual allocated transmission resource bandwidth. Part of the data packet will not be able to be transmitted and will be discarded at the interface; for a large data block, any small part discarded will cause the entire data block to be invalid, so the entire block of data has to be retransmitted over time at the upper layer

Since there are few effective data transfers, most of them need to be retransmitted, so the data transfer efficiency of this method is relatively low
