With reference to the accompanying drawings embodiments of the invention are described.The element described in an accompanying drawing of the present invention or a kind of execution mode and feature can combine with the element shown in one or more other accompanying drawing or execution mode and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process in illustrating.
Shown in Figure 1, be the structure chart of a kind of execution mode of hybrid network system of the present invention.
In the present embodiment, hybrid network system comprises server 10, wireless network portion 30 and cable network portion 20.
Wherein, server 10 for access carrier network, and is connected with cable network portion 20.
Cable network portion 20 comprises the first modulator-demodulator 21 and multiple second modem 22.First modulator-demodulator 21 for access carrier network, and connects at least one second modem 22, makes second modem 22 through the first modulator-demodulator 21 access carrier network.Second modem 22 is for being connected with wireless network portion 30, and such as, second modem 22 can be connected with wireless network portion 30 by Ethernet interface.
Wireless network portion 30 comprises multiple wireless router 31, and each wireless router 31 is connected with one of them second modem 22, for launching wireless network signal within the scope of certain space.
Server 10 also for being multiple wireless router 31 allocate communications frequency range, makes the communications band of the multiple wireless routers 31 at adjacent space operated within range different.
Such as, in residential building, arrange the hybrid network system in present embodiment.Can arrange first modulator-demodulator 21 in each family, this first modulator-demodulator 21 is connected to server 10, by server 10 access carrier network.In each room at each family, can arrange second modem 22, the multiple second modems 22 in same family are connected with the first modulator-demodulator 21 in this family by cable network.The wireless router 31 in each room is connected with the second modem 22 in this room, for launching wireless network signal in certain space scope (such as, in this room scope).Server 10 is also each wireless router 31 allocate communications frequency range, makes the communications band of multiple wireless routers 31 that (adjacent room as same floor) works within the scope of adjacent space different.Because general residential building all adopts armored concrete to build, between the room of contiguous floors same position, interference is general less, disturbs between the room thus can not considering contiguous floors same position.
Because the communications band of the wireless router 31 in adjacent space is different, the mutual interference between adjacent wireless router 31 can be avoided.
As a kind of execution mode, server 10 can adopt recursive algorithm to select the communications band of each wireless router in the communications band of predetermined quantity.
As shown in Figure 2, be a kind of communications band method of salary distribution of execution mode.
Suppose that each floor has 4 families, each household has 4 rooms, and server 10 can according to the method for salary distribution as shown in Figure 2, and the wireless router 31 for each room distributes a communications band, makes the communications band of the wireless router 31 of same layer adjacent room different.
As shown in Figure 3, be the communications band allocation model of another kind of execution mode.
Each floor of same hypothesis has 4 families, each household has 4 rooms, if also considered disturbing between the room of contiguous floors same position, server can according to the method for salary distribution as shown in Figure 3, wireless router 31 for each room distributes a communications band, make the communications band of the wireless router 31 of same layer adjacent room different, and in contiguous floors, the communications band of the wireless router 31 in the room that position is identical is also different.
Generally speaking, server 10 needs at least to choose 4 different communications and can reach the different object of neighbouring wireless router 31 communications band.
In one embodiment, each wireless router also comprises interference control module, and server also comprises state modulator module.
The interference control module of arbitrary wireless router is for detecting the interference of the first wireless router to this wireless router, and the first wireless router is other wireless routers arbitrary that in multiple wireless router, communications band is identical with this wireless router.
Parameter adjustment module is used for when interference value exceedes predetermined value, regulates the emission parameter of the first wireless router, makes interference value be not more than predetermined value.
Such as, interference control module receives the signal of the wireless router in other room identical with this wireless router communications band by scanning communications band, determines interference attenuation factor D i and by cable network portion (i.e. the second modem of correspondence and the first modulator-demodulator).Require in measurement that signal sending end adds at packet and launch signal to noise ratio snr t, such receiving terminal can obtain decay factor by the difference of received signal to noise ratio SNRr and transmitting signal to noise ratio snr t.
Di=SNRt-SNRr
Consider be positioned at room mobile terminal device (such as, mobile phone, panel computer etc.) can send at room diverse location and receive this factor, the interference attenuation factor counted on can reflect the same communication frequency range attenuation (when using same communications band) of adjacent room comprehensively.The minimum value of decay factor can be selected as conservative frequency planning foundation.
This measurement can count on " wireless " neighbours in each room, and the mutual signal attenuation factor.Decay factor is larger, and isolation is better.Sometimes, physically non-conterminous room because isolation the bad neighbours that also may become in air interference meaning.
The SNR that the signal received when adopting same frequency is no more than certain power P i(interference signal on N is made an uproar at the end of radio receiver can be set to the index of the interference of adjacent room), such as 3dB.Can judge whether interference exceeds standard simply:
Pt–Di≤Pi
Pi=N+3
Pt is the power of wireless device (wireless router in this room or terminal equipment) when working, and Di is attenuation coefficient, embodies the wireless isolation between room.Isolation is larger, disturbs less.
Or, in order to reduce the interference between contiguous floors co-located room further, 180 degree of half-phase antennas can be added on wireless router 31, making emitted energy be gathered in direction up, and signal is down very weak, thus strengthening upper downstairs between isolation.
If after emission parameter regulates, interference does not still meet the demands, can will disturb that one of them of two rooms that exceed standard uses a new communications band all not identical with each communications band used instead and another communications band remains unchanged, thus guarantee not interference.
Such as, as shown in Figure 4, suppose that the first family of ground floor and the communications band at the second family are that two rooms of " 1 " disturb each other and exceed preset value, so the communications band in the second corresponding room, family can be adjusted to " 5 " from " 1 ", and " 5 " are not used new communications band in any family of any one deck, so, because the communications band in this room at the second family is different from the communications band in other any room, can ensure between this room and other any room all noiseless.
Shown in Figure 5, be the anti-interference control method of the hybrid network based on hybrid network system of the present invention, comprise:
S10: server 10 is multiple wireless router 31 allocate communications frequency ranges, makes the communications band of the multiple wireless routers 31 at adjacent space operated within range different; Wherein, server 10 adopts recursive algorithm to select the communications band of each wireless router in the communications band of predetermined quantity, such as, selects the communications band of each wireless router in the communications band more than 4 or 4.
S20: the interference control module of arbitrary wireless router detects the interference of the first wireless router to this wireless router; Wherein the first wireless router is other wireless routers arbitrary that in multiple wireless router, communications band is identical with this wireless router;
