Description

Method for scheduling uplink information and network side device

Technical field

The embodiments of the present invention relate to mobile communication technologies, and in particular, to a method for scheduling uplink information and a network side device.

Background technique

In the General Packet Radio Service (GPRS) and Enhanced GPRS (EGPRS) systems, each time slot can carry a Packet Data Channel (PDCH), and one PDCH can be multi- The terminals are shared by time, and one terminal can also be assigned multiple PDCHs. In addition, GPRS introduces the concept of radio blocks: bursts with the same slot number on four consecutive TDMA frames are called a radio block. The wireless block is the basic unit of GPRS for data transmission. Data transmission in GPRS is accomplished by establishing a Temporary Block Flow (TBF). Data generated by clicking a link on a web page can be transmitted by establishing a temporary block flow. The downlink TBF is used by the network to send data to the terminal, and the uplink TBF is used by the terminal to send data to the network.

For the downlink TBF, the terminal needs to receive each radio block on the one or more downlink PDCHs allocated in the downlink TBF, and check the Temporary Flow Identity (TFI) in the radio block headers, if the TFI is equal to The TFI of the downlink TBF indicates that the radio block belongs to the downlink TBF. For the uplink TBF, in order to avoid the collision of multiple terminals, the network indicates in a certain way which terminal of each radio block resource of an uplink PDCH belongs to (that is, which terminal can transmit data in the radio block period).

However, when a large number of terminals need to access at the same time or in the same time period, there may be cases where access is denied due to insufficient PDCH resources, and more unnecessary access conflicts may be caused due to repeated attempts of the terminal to access.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Currently, when scheduling uplink information, the network side device may use a Dynamic Allocation (DA) method or an Extended Dynamic Allocation (EDA) method to schedule a mobile station (Mobi le Station, referred to as MS). ) The terminal sends uplink information. For example, the network side device allocates a plurality of uplink packet data channels (PDTSs) to the MS. When the uplink information is scheduled by using the DA mode, the MS monitors the uplink state identifiers on all downlink PDCHs corresponding to the uplink PDCH. The state flag (referred to as USF) transmits the uplink information on the uplink PDCH corresponding to the downlink PDCH of the USF that monitors the MS. When the uplink information is scheduled by the EDA, the MS corresponds to the uplink PDCH with the lowest slot number in the multiple uplink PDCHs. The downlink PDCH starts monitoring the USF. When monitoring the USF of the MS, it does not continue to monitor the downlink PDCH with a higher slot number, but monitors the uplink PDCH corresponding to the downlink PDCH of the USF of the MS and the slot number. Uplink information is sent on all high uplink PDCHs. Further, in the DA mode and the EDA mode, the granular scheduling mode may also be combined. When the MS monitors the USF of the MS in the downlink radio block of a downlink PDCH, the MS does not monitor the downlink radio block on the downlink PDCH. The downlink radio block is set to transmit uplink information on the uplink radio block of the USF that monitors the MS and the uplink radio block corresponding to the preset number of downlink radio blocks.

The above-mentioned DA mode or EDA mode, or any combination of the above two methods and granular scheduling, is a scheduling method for uplink TBF.

When scheduling the downlink TBF, the network may notify the terminal to send an Ack/Nack response message on the predetermined uplink block, in order to obtain the downlink information, in order to obtain the downlink information. It can be a downlink control message. In addition, the feedback period of the downlink information reception situation (that is, the polling period) is related to the throughput of the downlink service. If the feedback of the downlink information is not timely, the throughput of the downlink service will be reduced. If the period of the acceleration feedback increases the consumption of uplink resources, the number of users in the uplink service will be affected. Embodiment 1
