Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention provides a kind of method and device of disturbing of preventing, can effectively prevent the interference between the WLAN AP of the portable terminal of wide area network in the wireless home gateway and metropolitan area network.
The method of disturbing that prevents that the embodiment of the invention provides comprises:
Receive real-time working channel number, and the real-time working channel number of wireless local network connecting point of the portable terminal of wide area network;
When the real-time working channel number of the real-time working channel number of the portable terminal of this wide area network and/or wireless local network connecting point causes the channel number of interference to be complementary with the meeting of preserving in advance, portable terminal or this wireless local network connecting point to this wide area network send interrupt signal, make the portable terminal of this wide area network or this wireless local network connecting point switch to the working channel that can not cause interference.
Because the portable terminal of wide area network and the operating frequency range of WLAN are fixed, and the operating frequency of having only the part portable terminal can interfere with the part operating frequency of WLAN AP, for example, when the operating frequency of portable terminal was 830MHz in the frequency range 5, its parasitic 3 subfrequency that produce was 2490MHz.This harmonic component has exceeded in the operating frequency range of WLAN, concerning WLAN AP, do not constitute interference, can't influence WLAN AP receiver sensitivity on this frequency, when the operating frequency of portable terminal is operated in frequency range 1 or frequency range 2, his harmonic component not in the operating frequency range of WLAN AP, can't form Harmonic Interference; Which operating frequency that therefore can precompute portable terminal can be disturbed which operating frequency of WLAN, finds out the affiliated channel number of these operating frequencies and preserves;
Claim in the embodiment of the invention that the device of the above method of execution is a message handler, when message handler causes the channel number of interference to be complementary at the real-time working channel number of the real-time working channel number of the portable terminal of finding described wide area network, wireless local network connecting point with the meeting of preserving in advance, promptly make the portable terminal of wide area network or wireless local network connecting point switch to the working channel that can not cause interference, effectively avoided the generation of disturbing by interrupt signal.
Further, can use independent register to preserve the channel number that can cause interference, preservation can cause the register of the channel number of interference can be called as the collision channels information register, can certainly be kept in other existing registers.The collision channels information register can independently be present in the home gateway, also can be integrated in the message handler.
With the channel number in the portable terminal of wide area network is A, and channel number is that 3 subharmonic that the channel of A produces can be fallen in the receiving belt of WLAN, and the part operating frequency generation of WLAN is disturbed; Channel number with WLAN is B, and channel number is the 3 subharmonic interference that the channel of B can be moved terminal; If have only working channel that the portable terminal of wide area network uses number to be A, the working channel of WLAN AP number is not B, portable terminal will can not cause interference to WLAN AP so, vice versa, therefore the working channel that only uses at the portable terminal of wide area network number is A, when the working channel of WLAN AP number is B, just might produce interference.
Can preserve channel number A and channel number B simultaneously in the collision channels information register, when message handler mates simultaneously at the real-time working channel number of the real-time working channel number of the portable terminal of wide area network and wireless local network connecting point, send interrupt message according to predetermined rule to the portable terminal or the WLAN AP of wide area network, make the portable terminal of wide area network change to non-A working channel, or make WLAN AP change to non-B working channel to avoid conflict; Message handler also can only be compared a kind of working channel wherein, for example, only compare the real-time working channel number of the portable terminal of wide area network, as long as it is A, just notify it to change to non-A working channel, or only compare the real-time working channel number of WLAN AP, as long as it is B, just notify it to change to non-B working channel, same like this can avoiding conflict;
Further, 3 subharmonic that can preserve generation in the collision channels information register can be fallen the channel number of the described portable terminal in the receiving belt of WLAN (wireless local area network), and wireless lan channel that accordingly can be disturbed number, for example, the channel number that 3 subharmonic that produce can be fallen the portable terminal in the receiving belt of WLAN (wireless local area network) has 3 X1, Y1, Z1, X1 can be the WLAN working channel generation interference of X2 to channel number, Y1 can be the WLAN working channel generation interference of Y2 to channel number, Z1 can be the WLAN working channel generation interference of Z2 to channel number, then preserve X1/X2 in the collision channels information register, Y1/Y2, Z1/Z2, message handler is at the real-time working channel number of the portable terminal of wide area network, mate X1/X2 simultaneously with the real-time working channel number of wireless local network connecting point, or Y1/Y2, or during Z1/Z2, send interrupt message according to predetermined rule to the portable terminal or the WLAN AP of wide area network, make the portable terminal change work at present channel of wide area network, or make WLAN AP change work at present channel to avoid conflict.
Below all be the method for disturbing from the angle of message handler preventing of describing that the embodiment of the invention provides, during the method disturbed preventing of describing from the portable terminal of wide area network or WLAN AP angle that the embodiment of the invention provides, comprise:
Send the real-time working channel number to message handler;
When receiving the interrupt signal that described message handler sends, switch to the working channel that can not cause interference.
Now be described with example, the flow chart of the method that Fig. 1 disturbs for preventing of providing of the embodiment of the invention comprises:
101, message handler receives real-time working channel number, and the real-time working channel number of wireless local network connecting point of the portable terminal of wide area network.
102, message handler judges whether receive two real-time working channel numbers causes the channel number of interference to be complementary with the meeting of preserving in advance; Be execution in step 103 then, otherwise return step 101;
The method of judging may refer to the above description.
103, message handler sends interrupt signal according to predetermined rule to the portable terminal or the wireless local network connecting point of wide area network;
The rule of subscribing can be that the portable terminal with wide area network serve as preferential, sends interrupt signal to WLAN AP, also can be widely preferential with WLAN AP, to the portable terminal transmission interrupt signal of territory net, also can be to send to one of them at random.
104, the portable terminal of wide area network or WLAN (wireless local area network) switch to the working channel that can not cause interference after receiving interrupt signal.
Flow process finishes.
