Radio communication system for notifying no communication state, device and method for said system

Abstract

A communication system includes: a server (100) for transmitting a connection request to a cellular phone (200) through a cellular phone network (400) when receiving the connection request from a communication station (600) to the cellular phone (200); the cellular phone (200) for establishing a Bluetooth communication channel between the cellular phone (200) and a hot spot computer (300) located around the cellular phone (200) in response to the connection request received from the server (100); and the hot spot computer (300) for transmitting data received from the cellular phone (200) to the server (100) through a network (500) via the Bluetooth communication channel so as to communicate the cellular phone (200) with the communication station (600). When the communication channel between the cellular phone (200) and the hot spot computer (300) cannot be established, the cellular phone (200) transmits information which represents a reason that the communication channel cannot be established, to the communication station (600) through the server (100).

Description

field of invention [0001] The present invention relates to a wireless communication system that receives a connection request from a communication bureau and connects a communication bureau with a mobile phone, and particularly relates to a communication technology of a wireless communication system, the wireless communication system includes: a server device that receives a connection request from a communication bureau request, the mobile phone performs connection request processing; and the communication device, connects to the server device, and communicates with the mobile phone. Background technique [0002] Depending on whether the mobile phone is within the range of radio waves from the wireless base station or whether the mobile phone is in standby mode, the wireless communication system may not always be able to communicate with the wireless base station. Therefore, even if a communication station issues a connection request, the mobile phone may not be able to rec...

AI Technical Summary

Problems solved by technology

[0005] However, the wireless call receiving circuit of the mobile phone disclosed in the publication can only be adapted to receive

Therefore, when the main line is disconnected and cannot be used, the sending station cannot be notified of the detailed status of the mobile phone (located outside the range of the wireless base station, not connected to the power supply, the communication channel of the wireless base station is busy, talking, failure, etc.)

Therefore, there is a problem that the sender does not know why the connection cannot be made

[0006] In addition, even in the state where the main line can be used, the wireless call receiving circuit can only adapt to receive

Therefore, there is a problem that when establishing a connection between a mobile phone and a wireless base station, when both parties need common authentication information and connection information, this information cannot be shared immediately, and registration must be performed in advance.
