Wireless scheduling method, device and base station guaranteeing time delay service quality

Abstract

The invention discloses a wireless scheduling method, device and base station guaranteeing time delay service quality. The method is characterized by including the following steps that parameter information is determined according to preset service quality information, wherein the parameter information includes initial-moment information; data pack information to be sent to a target terminal is acquired, wherein the data pack information includes moment information corresponding to a data pack; a limiting timestamp of the data pack is acquired according to the initial-moment information and the moment information corresponding to the data pack; the data pack information is sent to the target terminal according to the limiting timestamp and a preset scheduling algorithm so that the data pack information can arrive at the target terminal within the time limited by the limiting timestamp. By means of the wireless scheduling method, data can be more effectively transmitted to a receiving end according to requirements for service quality, and user service experience is improved.

Description

technical field [0001] The invention relates to wireless network communication in a communication system, in particular to a wireless scheduling method, device and system for guaranteeing time-delay service quality. Background technique [0002] Wireless communication has been widely used all over the world, which greatly facilitates the communication between people. Wireless communication can provide various services, including voice calls and web page downloads, among others. A typical wireless communication system or network, such as an LTE (long term evolution, long term evolution) system, provides a wireless link connection for multiple UEs (user equipment, user equipment) in a cell through a base station to realize wireless communication. This wireless connection Usually a shared wireless spectrum is used. Such as figure 1 As shown, the base station uses the same wireless frequency band to provide wireless data communication services for multiple (two are shown in t...

[0004] In addition, even if different data packets of the same service are transmitted on the same network, because the transmission time is different, the specific conditions of the network will be different, resulting in the respective transmission delays of these different data packets on the network s difference

The base station uses shared spectrum resources to transmit data for different users, so the base station cannot guarantee that a single UE can obtain enough wireless resources to transmit data at any time

At the same time, due to the characteristics of wireless channel fading, the base station cannot guarantee the transmission rate of the UE when allocating wireless resources to transmit data.

In summary, when the UE requests real-time services such as streaming media, during the transmission process of the real-time service packet data, in addition to the different delays caused by Internet, P-GW, and S-GW transmissions, it also needs to experience delays caused by waiting for scheduling at the base station
