Embodiment Construction

[0018] Preferred embodiments of the present invention shown in the accompanying drawings will be described in detail below.

[0019] Typically, the base station server executes a broadcast procedure to broadcast data items to a plurality of mobile clients in one cycle.

[0020] Figure 1A and 1B Two scheduling methods are shown when the base station server broadcasts data wirelessly.

[0021] like Figure 1A As shown, the base station server runs a uniform broadcast program, and broadcasts all data items one by one in a broadcast cycle regardless of the data access frequency.

[0022] Additionally, if Figure 1B As shown, the base station server runs a non-uniform broadcast program to broadcast data items differently according to data access frequency. That is, in one cycle, data (d1) with high access frequency is broadcast more times, and data (d4-d7) with relatively low access frequency is broadcast less. At this time, the order of access frequency is d1>d2, d3>d4-d7.

Abstract

A method for processing query effectively in a radio data broadcast environment is able to minimize a query response time by pre-declaring data items which are wanted to be accessed by a mobile client before the query is operated, and by obtaining data of the pre-declared data items in advance from a radio space regardless of data transmitting order.

Description

field of invention [0001] The invention relates to the field of mobile communication, in particular to a method for efficiently processing queries in a wireless data broadcast environment. Background technique [0002] Recently, research on mechanisms for efficiently delivering information to mobile users in a wireless data broadcast environment is being actively conducted. This mechanism is used when a satellite or base station sends information to a mobile client. [0003] Broadcast-based transmission can be applied to various application areas, including sending information to multiple users. As examples of broadcast-based applications, there are stock trading, news, weather information, e-mail, electronic banking services, traffic information systems, and the like. [0004] For cases where a certain data item is required in these applications, the client can obtain the required data in standby mode while the server is sending the data. Thus, the benefit of broadcastin...
