Description
Technical field
The present invention relates to WiMAX field, especially, relate to a kind of shared method and wlan network system of wlan network resource.
Background technology
Broadband network is the emphasis of current each telecommunication carrier networks construction and operation, and when first three household electrical appliances letter operator is proposed the demand of WLAN wireless broadband network construction.
Because WLAN air interface uses the 2.4G frequency resource of opening of exempting to apply for, Ge Jia telecom operators can free field in this band frequency Resources Construction WLAN wireless broadband network.According to the IEEE802.11 agreement that WLAN wireless broadband network is followed, 802.11b/g equipment is operated in 2400-2483.5M frequency range, in order to make user can access network smoothly in WLAN wireless broadband network coverage, certain overlapping region may be there is between different WLAN access point (Access Point, AP) coverages.According to the modulation principle of channel distribution aerial in IEEE802.11 agreement and channel, as shown in Figure 1, in 2400-2483.5M frequency range, the channel of non-overlapping copies only has three, channel 1 (center frequency point is 2412M) respectively, channel 6 (center frequency point is 2437M), channel 11 (center frequency point is 2462M), the bandwidth of channel is 22M, therefore WLAN AP equipment is that setting is operated in 1 of this non-overlapping copies usually, 6, on 11 3 channels, and in the overlapping region of wlan network covering, use any one channel except these three channels, all can cause the interference of signal due to partly overlapping of channel, the throughput of WLAN AP equipment is reduced greatly, be exactly subscriber data traffic rate reduction for user, poor communications quality, the throughput and the client that affect WLAN AP use perception.
Secondly, due to the transmitting power of WLAN AP equipment lower (be generally 100mw or be no more than 500mw), the radio wave loss of place working frequency range is comparatively large (be it is generally acknowledged after penetrating indoor two walls in actual construction, WLAN signal quality is just unavailable), cause the coverage of single WLANAP equipment often limited, therefore generally can all with these three channels full in WLAN wireless broadband network is built, and good network service quality can be provided in order to ensure built WLAN wireless broadband network, build up the hot spot region that WLAN wireless broadband network covers, if other telecom operators entered follow-up will carry out the construction of WLAN wireless network, then certainly will cause interference to former carrier network, the network quality of self is also difficult to obtain effective guarantee, client's rights and interests of Liang Jia operator are finally caused to be encroached on, the brand of operator is affected.
In addition, WLAN AP equipment is due to the technical characterstic of self, international standard is lower for the spuious requirement of equipment, objective condition cause the spuious index of equipment relatively poor, therefore, suppose that the channel resource of three non-overlapping copies being distributed to respectively three telecom operators carries out wlan network construction in theory, and the power splitter of end is shared by three path combining technique realizations frequently, the resource such as coupler and antenna feeder, in fact such mixer must meet the index request of at least more than 80dB isolation between port, this is spaced apart 25M for channel center's frequency, in fact marginal belt wide frequency span is only the bandwidth of about 3M (as shown in Figure 1, channel 1 and channel 6, channel 6 and channel 11) want the isolation that can realize so high request, the technology of such tri-frequency combiner realizes being unpractical.Even if energy laboratory realizes, the conjunction pipeline equipment produced also is that bulky, cost are very high, technical difficulty is very large, closes pipeline equipment and cannot realize batch production and commercialization at all.Therefore, the mixer equipment that simultaneously will realize 1,6,11 these three channels conjunction roads is at least unpractical under current technical conditions.
Backward is proved, suppose technically likely to realize such three frequently to close pipeline equipments and realize three operators and close road realize single-point access by respectively taking a channel resource, the wlan network coverage that can build also is very limited, 802.11b/g equipment can only provide the air interface modulation rate of maximum 11M/54M, goodput is substantially at about 6M/22M, therefore be several more user's application scenarioss for hot spot region, the bandwidth that each user can distribute is an utterly inadequate amount.Under such wlan network, everywhere due to hot spot region also exists three channel signals of these three non-overlapping copies all simultaneously, therefore the dilatation of wlan network will be realized, as shown in Figure 1, just can not find the channel resource of " pure " at all, even if therefore realize by three Pin He road modes the wlan network that three operators share to build together, also be difficult to meet the network capacity extension that multiple access brings and the demand that network quality ensures, also by face network provider with after cannot the embarrassment of capacity expansion and upgrading, this and carrier class network are wanted to realize renewable electricity, can management and control, the basic demand of extendible capacity upgrading is far apart.

With reference to the accompanying drawings the present invention is described more fully, exemplary embodiment of the present invention is wherein described.Exemplary embodiment of the present invention and explanation thereof for explaining the present invention, but do not form inappropriate limitation of the present invention.
Fig. 2 is the schematic flow sheet of an embodiment of the inventive method.
The access point apparatus that the wlan network of this embodiment comprises access controller and is connected with access controller, as shown in Figure 2, this embodiment can comprise the following steps:
S102, access point apparatus broadcast identifies the difference access mark of each Operation Network, searches network belonging to oneself to enable the user in each Operation Network;

This embodiment utilize wlan network can support multiple access identify solve the technical barrier that carrier class multi-operator shares wlan network of building together, overcome frequency interferences problem when Duo Jia operator WLAN coexists, achieve safe Joint construction and sharing.This embodiment also successfully achieves docks with three operators independently wlan network chargings separately, certification and the effective of network management platform, can also realize the smooth expansion of wlan network and the upgrading to 802.11n in conjunction with hot spot region data service growth requirement.
In another embodiment of the inventive method, wlan network can be centralized control type wlan network.Alternatively, wlan network can be deployed in the same area and the centralized control type wlan network shared by multiple Operation Network.
Be compared with the group-network construction of core with employing switch, because general switch only supports configuration Management VLAN, therefore, can only access at most the network management platform of an operator, this shares for the scene of building together for Duo Jia operator, is obviously inequitable; And this embodiment is owing to being the network architecture adopting centralized control type, AP all on be linked to access controller, access controller possesses powerful hard core control and control ability, can directly to the AP equipment of external One's name is legion, have fairly perfect webmaster ability, the network management platform of Duo Jia operator easily can realize the operational management to wlan network based on access controller safely.Meanwhile, access controller can also configure associated rights easily, guarantees the safety of network management system.
In addition, switch is that the group-network construction of core is when wlan network traffic carrying capacity rises, need to increase WLAN AP equipment, because WLAN only has three limited frequency resources, therefore, want the WLAN AP equipment that realizes in the place of the AP deployed with devices comparatively denses such as conference and exhibition center newly increasing can with the harmonious coexistence of the WLAN AP equipment of same court, need to carry out channel to all WLAN AP of periphery, power is isoparametric distributes rationally, this is difficult to accomplish in actual environment, because the channel resource that can find to can not find suitable " totally " and the workload optimized and revised huge, on-the-spot Optimization Work is difficult to carry out, and poor effect.And under the network architecture of centralized control type, all AP unify to control by access controller, controller can regular Auto-Sensing wireless channel disturbed condition, and based on detecting situation, adjustment is optimized to AP, even if because dilatation increases AP newly, due under the management and control of same access controller, harmonious coexistence can be realized easily with periphery AP equipment, and control based on the unified of access controller, even if there is indivedual AP equipment to break down in network, service cannot be provided, periphery AP can coordinate in the control of access controller and realize optimizing and revising of power output under management, guarantee the integrality of the target area network coverage, realize good network self-healing protection.

In the another embodiment of the inventive method, access controller can be that each Operation Network distributes access bandwidth statically.Such as, access controller can be that each Operation Network distributes access bandwidth equably.
In the prior art, if the development of A carrier market better, the A client of operator access that same place is a large amount of, has almost taken the air interface bandwidth resource of AP, B and the C client of operator being so in this place certainly will be difficult to access, obviously very unfair for B and C operator.And this embodiment carries out relevant distributing rationally based on the powerful management and control ability of access controller, such as, the configuration of access bandwidth can be carried out based on access mark, when needs access ABC tri-operators, the air interface bandwidth of 54M can be divided into three parts, the maximum access that can only take as it of the client of such A operator identifies the bandwidth of distributing, for client's access of B and C operator leaves sufficient bandwidth leeway, therefore fair equity access can easily be realized, this is all fair for any operator, also be unusual equality, there is not any fighting for.
In an embodiment again of the inventive method, access controller can be dynamically that each Operation Network distributes access bandwidth.Such as, access controller dynamically can distribute access bandwidth for each Operation Network by the number of users of certification equably according to current access wlan network.
After network puts into effect, the resource utilization of bandwidth may be caused not high if adopt absolute fair method to distribute access bandwidth.And this embodiment carries out dynamic uniform distribution air interface bandwidth mode according to current access and by the number of users of certification can significantly improve the resource utilization of WLAN air interface bandwidth, also better can apply perception for client brings.
In the above-described embodiments, the number of access point apparatus can be more than one.
In addition, each Operation Network can based on snmp protocol visited WLAN network.
Effect after above-described embodiment realizes is consistent with the effect that Duo Jia operator builds separately, no matter give user perception or for operator's direct first line of a couplet network/platform equal indifference, and build together because hot spot region achieves the shared of Internet resources, wlan network quality on the contrary can be better, can be better to the perception of client.
