Problems solved by technology

[0003] However, the paging service protocol is usually represented by a POCSAG (Post Office Code Standardization Advisory Group) mode and a FLEX mode, wherein the POCSAG mode is used for the asynchronous transfer mode with a maximum transmission rate of 2.4kbps, and the FLEX mode is used for the maximum transmission rate. The synchronous transmission mode with a rate of 6.4kbps, therefore, the paging channel assigned to the existing paging service system has great limitations on the transmission rate and / or transmission capacity
[0004] Therefore, due to the limitation of the transmission rate in the paging service system, it is difficult to provide large-capacity data such as stock information service, sports information service, traffic information service, etc. in real time
For example, the limitation of the transmission rate in each channel of the paging service system makes it difficult to expand the utilization of unused resources (i.e., paging frequency)

Embodiment Construction

[0024] best practice

[0025] Preferred embodiments according to the present invention will be described in further detail below with reference to the accompanying drawings. When a paging system respectively transmits large-capacity data through multiple channels (for example, at least two channels) so as to provide large-capacity data such as stock information service, sports information service, traffic information service, etc., the pager according to the present invention receives and processes These large-capacity data are sent separately, and then the processed data is provided to the user in real time.

[0026] figure 1 A block diagram of a pager with simultaneous multi-channel scanning function according to the first preferred embodiment of the present invention is shown. The first embodiment exemplifies the case where frequency signals are transmitted through, for example, two channels whose frequency bands do not overlap with each other. The pager 100 includes tw...

Abstract

A paging system separately transmits high capacity data through at least two paging channels of limited transmission rates in order to provide the high capacity data in real-time. A pager receives and processes the paging frequency signal transmitted through at least two channels, thereby generating regenerated data not to be separated.

Description

field of invention [0001] The present invention relates to an acoustic signal device (i.e., a pager); and, more particularly, to a pager having a function of synchronous multi-channel scanning for receiving large-capacity data transmitted through multiple channels and a system for transmitting and The method to receive data. Background of the invention [0002] Recently, the rapid development of wireless mobile communication technologies such as cellular phones, personal communication services (PCS), personal digital assistants (PDA) and the like has led to a rapid decrease in the number of users of paging services and this trend seems to be in the future for a period of time will continue. The significant decrease in the number of users hides the available channel capacity allocated to the paging service, and therefore some schemes have been proposed to make proper use of the existing paging service system and the paging frequencies allocated thereto. For example, various...
