It is an operation | movement sequence diagram which shows the conventional operation | movement sequence of the data communication between each of 4).

In FIG. 6, PHS slave device 300 and PHS
In order to establish a data communication path with the HS parent device 210, first, a wireless call between them is connected. The PHS slave device 300 requests the PHS master device 210 for a wireless call connection (S31). PHS that received the wireless call connection request
Master device 210 determines whether or not the slave device requesting the connection is a slave device registered in the master device in advance, and permits or denies wireless connection (S31). After the wireless connection is made, a data link connection is performed between the slave device 300 and the master device 210 using a PHS data communication protocol such as PIAFS (S32). Slave device 300 / PH
After the wireless data link between the S parent devices 210 is established, a PPP (point-to-point protocol) generally used when performing data communication through a modem or the like
Make the link connection. The connection of the PPP link is performed by using an LCP (Link Control Protocol) for setting parameters of the PPP itself.
rotocol) negotiation phase (S33), authentication phase for performing user authentication (S34), NCP (Network Control) for performing setting related to network layer protocol
l Proto-col) The negotiation phase (S35) is roughly divided into three phases. At this time, authentication is performed by an external server, and IP (Internet P
roto-col) to get the address from the external server
When the HS parent device 210 is set, the PHS is set in the authentication phase or the NCP negotiation phase.
Master device 210 performs LAN access. After these phases are completed, data communication by IP becomes possible between the PHS slave device 300 and the PHS master device 210 (S3).
6). When data communication is performed between the PHS slave device 300 and the server 301 on the LAN 220, the PHS master device 210 serves as a repeater in the LAN section and the wireless section. By the way, at this time, if the L
A failure occurs in the AN transmission / reception function, and the PHS master device 210

Next, a process of establishing a wireless data link is performed according to the protocol that is the same on both sides (S2). Thereafter, a PPP connection process is performed (S3 to S5). During the PPP connection process, the authentication phase and the NCP negotiation phase
Access may be made in some cases. In this way PPP
After the connection is made, data communication by the IP protocol is performed between the slave device 107 and another network via the server 109 on the LAN, the terminal, or the router (S).
6). Here, during communication, LAN cable failure or LAN
It is assumed that data packets cannot be transmitted from master device 100 to LAN 108 due to a failure in the LAN transmission function of transmitting / receiving section 103 or the like. The LAN transmission / reception unit 103 detects a data packet transmission error by the transmission error detection function. However, if a predetermined number of transmission errors occur consecutively, the LAN transmission / reception unit 103 determines that a failure has occurred and notifies the management unit 104 (S7). The management unit 104 uses the display device 105 to display a failure occurrence. Further, the management unit 104 disconnects all the connected slave units once through the communication control unit 102 (S8 to S1).
0). After that, an attempt is made to notify a failure by the short message communication function to all the slaves registered in the management unit 104 of the master unit 100. The communication control unit 102 requests a failure notification to the communication control unit 102 (S11), and the communication control unit 102 transmits a short message to the first child device 107 via the wireless transmission / reception unit 101 (S12). The text of the short message is set in advance by the user or set in the management unit 104 of the parent device 100 from the beginning. At this time, if the short message communication cannot be performed because the power of the slave device 107 is not turned on or is not within the radio wave range of the master device 100, no notification is given to the slave device 107. The process proceeds to a notification process for the next slave unit 107A (S13, S1).
4). This process is performed for all the slave units registered in the management unit 104 of the master unit 100. A short message is transmitted to the child device that is within the radio wave range of the parent device 100 at that time among the child devices registered as the child device in this way, and is displayed on the display of the child device.
