Wireless local area network building method of the present invention may further comprise the steps:

(1) specify a website as soft access point (SAP, Software Access Point);

(2) specific drivers of installation and operation network interface card and configuration application system on site hosts;

(3) for SAP the group identifier of activating business (ESSID, Extended Service SetIdentifier are a sign of extended service set setting) is set;

(4) user site is selected the working method of oneself by user terminal system;

(5) user side is searched the beacon message that the AP in the current environment of living in sends by sending sweep signal, just it is added when receiving the beacon signal of SAP in the list of network identifications of access customer;

(6) user site is chosen the ESSID of SAP, and sends request primitives such as authentication, association to it;

(7) SAP receives the request primitive of user site, connects with it, and user site just can be carried out communication by SAP and other user like this, and so far, networking finishes.

In described step (2), system and combination of hardware realize standard features such as the AP side primitive of stipulating in IEEE 802.11 agreements is realized, network interface card management AP.

In described step (4), selected working method is the INFRASTRUCTURE pattern.

In described step (7), IEEE 802.11 standards are followed in the process strictness of connecting.

The method of the invention is by being provided with soft access point (SAP), thereby make the user under the situation that does not have WAP (wireless access point) (AP), can with other users online simultaneously together, and the method for the invention do not need special-purpose AP, can also save some hardware costs.In actual applications, the method for the invention can be used as the additional project of wireless universal local area network building scheme.

Embodiment

Below in conjunction with embodiment the method for the invention is further described.

The present invention is that many notebook computers, mobile PC or desktop computer are not having under private radio access point (AP) situation, utilizes a kind of method of the wireless network card composition WLAN (wireless local area network) of existing 802.11a or 802.11b/g standard.

The network-building method of WLAN (wireless local area network) as depicted in figs. 1 and 2 on the traditional sense, Fig. 1 is the general networking modes of telecom operators, this system comprises wireless network card, WAP (wireless access point) (AP), wireless access gateway (AG), wireless bridge (AB) and wireless access server a series of equipment such as (AS), has also finished the common functions that cable network had such as charging, authentication, mandate when finishing wireless access.Fig. 2 then is small office and enterprises simple networking mode commonly used, is made up of wireless network card and WAP (wireless access point) (AP) usually, mainly finishes wireless access and simple authentication function.

Generally speaking, the mode of operation of WLAN (wireless local area network) has two kinds: Infrastructure and Adhoc, wherein the Infrastructure pattern is meant (the Access Point by AP, access point) Hu Lian mode of operation, at this moment AP can be considered as the hub (HUB) in the conventional local area, (STA Station) realizes the interconnected of with other wireless or wireline equipment by AP to website.The Adhoc pattern then is a kind of more special WLAN (wireless local area network) mode of operation, the ESSID of this pattern by the wireless network card that need communicate with one another a group is made as with value and comes networking, thereby realize the mutual communication between these wireless devices, in this pattern, need not use AP.

The method of the invention is mainly used in the wireless local area network (WLAN) system under the Infrastructure pattern.The core thinking is that traditional access point (AP) is expanded, and realizes the establishment of WLAN (wireless local area network) under the particular surroundings (not having special-purpose AP environment) by the method that soft access point (SAP) is set, and its classical group net mode as shown in Figure 3.As can be seen, realize that key of the present invention is the realization of soft WAP (wireless access point) (SAP).So-called soft WAP (wireless access point) (SAP) is exactly to install on site hosts and operation configuration application system, makes it can realize the function of WAP (wireless access point) (AP).Because general WAP (wireless access point) (AP) itself is exactly a kind of special user site, distributed system (the DS that it can provide general STA not have, Distribution System) business function is so configuration-system is mainly used to provide the common user DS business that website is not had.The DS business mainly comprise connection, separation, transmission, integrated with function such as be connected again, the specific descriptions of each business have had detailed description in standard " IEEE802.11 standard the 11st part WLAN (wireless local area network) MAC and PHY layer describe in detail ".Summary is got up, and the configuration application system is mainly used to realize addressing, route and the forwarding capability of being connected of AP and target STA and data.

WLAN (wireless local area network) of the present invention is specifically implemented construction method can reduce following steps (as shown in Figure 4): at first specify a base station as SAP, and install and move the specific drivers and the configuration application system of network interface card on site hosts.The network interface card that this system class is similar on the special-purpose AP drives and hypervisor.It is by realizing the function (as the realization of 802.11 AP side primitive and to the management of connected network interface card etc.) of the standard of the AP that stipulates in IEEE 802.11 agreements with combining of hardware.For SAP is provided with ESSID, user site is selected the working method (being made as the INFRASTRUCTURE mode) of oneself by the user terminal system end then.User side is searched the beacon message that the AP in the current environment of living in sends by sending sweep signal, just it is added in the list of network identifications of access customer when receiving the beacon signal of SAP.Again then, user site is chosen the ESSID of SAP, and sends request primitives such as authentication, association to it.At last, SAP receives the request primitive of user site, connect with it (IEEE 802.11 standards are followed in the connection procedure strictness), user site just can be carried out communication by SAP and other user like this, and so far, networking finishes.

The typical case of the method for the invention uses as shown in Figure 3, and as can be seen, it is based on Fig. 2 and develops and come.Because Fig. 2 itself is exactly the subclass of Fig. 1, so it also is applicable to the networking mode of Fig. 1.
