Data scheduling platform of integrated information service broadcasting system

Abstract

The invention discloses a data scheduling platform of an integrated information service broadcasting system. The data scheduling platform comprises a control center, a real-time service data broadcasting scheduling subsystem, a non real-time service data broadcasting scheduling subsystem, a personalized data broadcasting scheduling subsystem and a channel adapting subsystem. The scheduling platform established by the invention can support broadcasting services of real-time service data and non real-time service data under the same broadcasting channel, support dynamic addition, deletion and data modification services and perform dynamic distribution, adjustment and recovery of broadband; a single-channel broadcasting or multi-channel parallel broadcasting mode and different scheduling strategies are adopted in different data services to meet the time limitation requirement of the real-time data service and reduce the data access time of the non real-time data service; and when the multi-channel parallel broadcasting mode is adopted for data broadcasting, the data scheduling platform supports the change capable of adapting to data classification, dynamically adjusts the distributedchannel number and bandwidth, meanwhile supports the user request-based data broadcasting scheduling service, performs reasonable scheduling according to the factors such as data access probability, request deadline, request data length and the like, and meets the requirements of various indexes.

Description

technical field [0001] The invention relates to a data scheduling platform of an integrated information service broadcasting system, which belongs to the technical field of data broadcasting. Background technique [0002] In recent years, with the rapid development of wireless communication technologies such as cellular communication, wireless LAN and satellite communication, information services based on wireless networks have emerged continuously, enabling wireless network devices to access the required information anytime and anywhere through the wireless network, including real-time traffic information. , real-time stock quotes, news information, weather forecast and shopping information, etc. It integrates mobile computing, mobile database and wireless communication technologies, and has the advantages of broadcast channel sharing, irrelevant number of users, large downlink bandwidth and low cost. Data broadcasting is an effective means of data acquisition and data rele...

Problems solved by technology

The flat broadcast scheduling method is suitable for the situation where the user data access patterns are relatively uniform. When the user data access patterns are quite different, for example, 80% of users access 20% of the data, because the data with high access probability and the data with low access probability have the same The sending frequency, so this broadcast method makes the system performance drop sharply
