A data scheduling method and system and related equipment

Abstract

The embodiment of the invention discloses a data scheduling method, system and related equipment, which can effectively improve the multiplexing degree of packet wireless channels and the success rate of packet wireless access. The method in the embodiment of the present invention includes: the terminal acquires the time feature of the downlink radio block and the USF allocated to the terminal, the time feature of the downlink radio block is used to indicate that the terminal needs to detect the downlink radio block of the USF; Downlink wireless block; when receiving a downlink wireless block that meets the time characteristics, judge whether the USF contained in the downlink wireless block is the same as the USF allocated to itself, and if they are the same, send uplink data on the uplink PDCH corresponding to the downlink PDCH or signaling. The embodiment of the present invention also provides a data scheduling system and related equipment. The embodiments of the present invention can effectively improve the multiplexing degree of packet radio channels and the success rate of packet radio access.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data scheduling method and system and related equipment. Background technique [0002] With the continuous development of network technology, General Packet Radio Service (GPRS, General Packet Radio Service) has been widely used. [0003] All data transmission in GPRS is accomplished by establishing a temporary block flow (TBF, Temporary BlockFlow). One TBF is used to complete the transmission of several user data (such as the data generated by clicking a link on a web page). For the uplink TBF, since multiple terminals may be multiplexed on the same data traffic channel (PDCH, Packet Data Channel), in order to avoid conflicts, the network must determine in a certain way which resource each uplink radio block of a certain PDCH belongs to. terminal (that is, which terminal can send data on the uplink radio block). [0004] At present, the GPRS network adopts the uplink resour...

Problems solved by technology

[0006] However, since the USF only carries 3 information bits, there can only be at most 2 to the power of 3 different USFs in the same TBF period on a PDCH, that is, only 8 terminals can be multiplexed at most

When a large number of terminals need to access at the same time or within the same time period, they will be denied access due to insufficient PDCH resources, and more unnecessary access conflicts and access failures will occur due to repeated access attempts of the terminals. Therefore, the success rate of wireless access is reduced
