A method and system for scheduling transmission resources

Abstract

The invention provides a method and a system of dispatching transmission resources. The method of dispatching the transmission resources comprises the following steps: Step A. allocating the transmission resources to the service by consulting generated protection flow, wherein the allocated transmission resources are smaller than or equal to the protection flow; Step B. judging whether the transmission resources run out or not and turning to the step E if the transmission resources run out, otherwise continuing to determine whether all the service are visited and turning to step C if all the service are visited, otherwise turning to step A; Step C. visiting the service again to supplement the transmission resources needed in the transmission; Step D. judging whether the transmission resources run out or not, and turning to step E if yes, otherwise continuing to determine whether all the service are visited or not, turning to step E if yes otherwise turning to step C; Step E. implementing the data transmission after the allocation process is finished. The invention further provides a system of dispatching the transmission resources. The method and the system of dispatching the transmission resources allocate the transmission resources according to the actual data transmission demand, avoid the waste of the resources in the fixed or static allocation of the transmission resources, and can prevent the low transmission efficiency caused by 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) agreement, four types of services are defined: conversational, that is, real-time conversational services such as voice; streaming, that is, real-time audio and video streaming services ; Human-computer interaction service (interactive), that is, interactive services such as web browsing; background service (background), that is, data transmission services between machines. The ...

[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
