Data scheduling method and system thereof, and correlated equipment

Abstract

The embodiment of the invention discloses a data scheduling method and a system thereof, and correlated equipment, so that multiplexity of a packet radio channel and a success rate of packet radio access can be effectively improved. According to the embodiment of the invention, the method comprises the following steps that: a terminal obtains a time characteristic of a downlink radio block and an uplink state flag (USF) that is distributed to the terminal, wherein the time characteristic of the downlink radio block is used for indicating that the terminal needs to detect a downlink radio block of the USF; a downlink radio block that is sent by network side equipment at a downlink packet data channel (PDCH) is received; when a downlink radio block that accords with the time characteristic is received, it is determined whether a USF contained in the downlink radio block is identical with a USF that is distributed to the downlink radio block itself; and if so, uplink data or signaling are / is sent at an uplink PDCH that is corresponded to the downlink PDCH. In addition, the embodiment of the invention also provides a data scheduling system and correlated equipment. According to the embodiment of the invention, multiplexity of a packet radio channel and a success rate of packet radio access can be effectively improved.

Description

Technical field [0001] The present invention relates to the field of communications, and 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 completed by establishing a temporary block flow (TBF, Temporary BlockFlow). One TBF is used to complete the transmission of several user data (such as data generated by clicking a link on a web page). For 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 which uplink radio block resource of a certain PDCH belongs to in a certain way Terminal (that is, which terminal can send data on the uplink radio block). [0004] At present, the GPRS network adopts the uplink resource allocation meth...

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
