Slave communication appts. used in radio lan system, control method of slave communication appts. and control program

Abstract

The present invention provides a wireless LAN system which allows each slave communication device to perform originating by itself to a telephone apparatus outside the network through a host station without relaying through a master communication device while a single wireless telephone line is used, and does not require particular processing such as authentication on the host station side. Each transmission / reception means 5 is controlled to switch between a first state in normal times in which a transmission / reception means 5 of a master communication device 1 is turned on and transmission / reception means 5 of respective slave communication devices 2 are turned off and a second state at the time of control delegation in which the transmission / reception means 5 of the master communication device 1 is turned off and only the transmission / reception means 5 of any one of the slave communication devices which is a subject of control delegation is turned on, and when a reason of originating control delegation to any slave communication device occurs in the first state, an originating control delegation signal for permitting the transmission / reception means of that slave communication device to be turned on is transmitted from the master communication device 1 to that slave communication device through the respective short-range wireless communication means to perform switching to the said second state.

Description

technical field [0001] The present invention relates to a sub-communication device and a control method for a wireless LAN system for network-connecting a plurality of electronic devices using a short-distance wireless communication unit. The configuration, control method, etc. of a child communication device that receives a control request from a master communication device that governs the entire network and transmits a call to a telephone device outside the network. Background technique [0002] In recent years, mobile communication telephones have developed rapidly, and the number of users of mobile communication telephone lines (hereinafter referred to as wireless telephone lines) exceeds that of fixed telephone lines due to reductions in call charges and sales of new equipment. Therefore, a user generally has two types of mobile phone using a wireless phone line and a fixed phone using a fixed phone line, and communicates with the fixed phone in the house and with the ...

AI Technical Summary

Problems solved by technology

[0013] However, in the system proposed above, when each sub-communication device that accepts the control entrustment uses the sub-ID to perform radiotelephone communication with a telephone device outside the LAN, the master station needs to perform authentication on the correspondence between the sub-ID and the main ID. There is a disadvantage that the host office side (communication carrier side) bears the processing
