Shown in Figure 1, Fig. 1 is the structural representation of the system for strengthening mobile device Received signal strength of first embodiment of the invention.As shown in Figure 1, the place that the system application signal strength signal intensity that the present embodiment discloses is more weak, such as tunnel, bomb shelter etc., this system comprises: the first mobile device 11, second mobile device 12 and other mobile devices 13, and wherein the first mobile device 11, second mobile device 12 and other mobile devices 13 are preferably mobile phone.Mobile phone optimum signal range of receiving is-40 ~-70dbm, and within the scope of this, mobile phone signal is best, is shown as full lattice (such as 5 lattice); Mobile phone is shown as 3 lattice when-90dbm, now can ensure the basic call function of mobile phone, and the range of signal of therefore mobile phone reception, at-40dbm ~-90dbm, just can ensure the basic call of user, and the signal strength threshold namely preset is preferably-90dbm.
The present embodiment is applied in tunnel with system and is described in detail.First mobile device 11 detects the first signal strength signal intensity, and the first signal strength signal intensity is the signal strength signal intensity of the first mobile device 11 self; And the first signal strength signal intensity and the signal strength threshold preset are compared; If the first mobile device 11 judges that the first signal strength signal intensity is more than or equal to signal strength threshold, namely the first signal strength signal intensity can ensure that the first mobile device 11 is conversed substantially, can become interim communication base station.Second moves this equipment 12 detects secondary signal intensity, and secondary signal intensity and the signal strength threshold preset is compared; If the second mobile device 12 judges that secondary signal intensity is less than signal strength threshold, namely secondary signal intensity can not ensure that the second mobile device 12 is conversed substantially; Secondary signal intensity is sent to the first mobile device 11 by the second mobile device 12.Now as shown in Figure 2, the length in tunnel is L to the position relationship of the first mobile device 11 and the second mobile device 12, and the signal strength signal intensity at the gateway place in tunnel is comparatively strong, and namely the first mobile device 11 is positioned at tunnel face, and the first signal strength signal intensity is greater than-90dbm.The signal strength signal intensity of the position D of setpoint distance tunnel face d is-90dbm, then the second mobile device 12 is compared position D and more goed deep in tunnel, and secondary signal intensity is less than-90dbm.The distribution of signal curve X as shown in Figure 2 in tunnel.
