detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. The components of the embodiments of the invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention provides a method and device for accessing a wireless network by taking authentication of a Wi-Fi network in an OPEN (open, free) mode as an example, and the specific description is as follows.

Referring to the flow chart of the wireless network access method shown in Figure 1, the method includes the following steps:

Step S102, the access device monitors the probe request of the wireless terminal, where the probe request carries the SSID. The wireless terminal in the embodiment of the present invention may also be called a mobile terminal, and specifically may be a mobile phone, a tablet computer, or other portable electronic devices.

The access device (such as AP or AC (access controller)) in the Wi-Fi network will monitor the probe request in the coverage area of the local network in real time, and the probe request is usually a PROBEREQUEST message, which carries the SSID.

Step S104, the access device checks whether the above SSID is consistent with the identifier of the wireless network configured by itself (referring to the access device).

Step S106, if not consistent, the access device performs SSID service self-configuration, and connects the wireless terminal to the wireless network corresponding to the SSID.

In related technologies, if the SSID in the probe request is consistent with the identifier of the wireless network configured by the access device itself, the access device will directly connect the wireless terminal; If the IDs are inconsistent, the access device will directly reject the access of the wireless terminal. In the above method of the embodiment of the present invention, when the SSID in the probe request is inconsistent with the wireless network identifier configured by the access device itself, the access device does not directly reject the wireless terminal, but performs service self-configuration according to the SSID in the probe request , connect the wireless terminal to the wireless network, so that the user does not need to manually select the Wi-Fi network to access through the SSID list returned by the detection request, and the access process can be completed automatically, which simplifies the process of connecting the wireless terminal to the Wi-Fi network The process effectively improves the seamless roaming switching service of the wireless terminal and improves the user experience.

During specific implementation, the self-configuration of the SSID by the access device may include: the self-configuration of the service for the SSID by the access device according to a service pre-customized by the network manager or network operator.

Considering that the access device in the embodiment of the present invention can be a wireless hotspot built by the user, the access device can provide personalized services to the connected wireless terminals, and these services can be sent to the wireless terminals in the form of push messages, Based on this, the above method further includes: the access device sends the push message provided by the push server to the wireless terminal, and the push server may be a push server configured for the access device. The push message can be delivered to the wireless terminal when the wireless terminal initiates an HTTP connection, or can be delivered to the wireless terminal when the wireless terminal requests other services. The specific sending process can be realized by using a push (Push) technology, which is a technology based on the server actively sending information to the client. Compared with the traditional "pull" (Pull), the main feature of Push is that the server actively sends information, rather than the client initiates the request. Its advantage lies in the initiative and timeliness of information, which can push information to users at any time. Push content in the field of mobile communications can cover news, weather, sports events, stock market quotations, as well as upgrade reminders, Weibo information, SNS friend dynamics and e-reading content, etc.

Considering that there will be various wireless terminals in the coverage area of the network where the access device is located, some wireless terminals may only appear in this area occasionally, some even appear once in a long time, or never appear again after appearing once, In order to prevent too many SSIDs self-configured by the access device, which affects the performance of the device, the above method can use an aging mechanism to delete some SSID configurations. Based on this, the above method further includes: the access device periodically counts the access situation of the self-configured SSID, and deletes the configuration content of the SSID when the time period for which the SSID does not access the service exceeds a set threshold. Wherein, the statistical cycle can be set according to experience, for example: one week. Through this aging mechanism, part of the SSIDs configured on the access device can be effectively deleted, and only the SSIDs used by recently visited wireless terminals are retained, which improves the utilization of the storage space of the access device, and thus improves the performance of the device.

In addition to only monitoring the detection request, the above-mentioned access device can also broadcast the public network identifier of the commonly used wireless network, so that the wireless terminal can directly carry the public network identifier in the detection request according to the historical usage. After the ingress device has self-configured the service of the public network identifier, the wireless terminal is connected to the wireless network of the public network identifier, and when other wireless terminals send detection requests carrying the public network identifier, they will be able to directly The wireless terminal access avoids self-configuration of too many SSIDs. Based on this, the above-mentioned access device monitoring the detection request of the wireless terminal may include: the access device sends a broadcast frame BEACON, and the BEACON carries the public network identifier; the access device receives the detection request of the wireless terminal, wherein the detection request carries Has a public network ID.

Refer to the signaling interaction schematic diagram of the access method of the wireless network shown in Figure 2, wherein, the AP (wireless access point) provides the wireless service of the OPEN mode authentication, and the wireless service with the WLAN (Wireless Local Area Networks, wireless local area network) function enabled After entering the coverage area of this AP, the terminal performs the following signaling interaction process:

(1) The wireless terminal sends a PROBE REQUEST carrying a non-empty SSID (equivalent to the above-mentioned probe request, which can also be called a probe message or a probe message), and the SSID can be a previously connected wireless network service;

(2) The AP receives the PROBE REQUEST from the wireless terminal, performs SSID service self-configuration according to the SSID in the probe message, and provides the SSID wireless access service;

(3) The AP carries the SSID service through the BEACON message, and maintains the SSID service access statistics;

(4) The wireless terminal receives the BEACON message containing the SSID, actively initiates the 802.11 access process, and accesses the wireless network served by the SSID;

(5) The wireless terminal accesses successfully;

(6) The wireless terminal actively initiates an HTTP connection;

(7) The AP cooperates with the corresponding push server to push messages to the wireless terminal, such as pushing advertisement services.

In order to effectively use the storage area of the AP, the AP can periodically perform self-configured SSID service access statistics, and perform aging deletion on SSIDs that have not been accessed for a long time.

The self-configuration of the access device (AP or AC) in the embodiment of the present invention means that the AP does not provide the SSID service initially, but configures the SSID service and related policies on the device according to the SSID in the PROBE REQUEST, specifically Policies can be set according to the specific plan of the network administrator, such as whether to perform PORTAL authentication.

In order to simplify the SSID configured on the access device, the access device can also induce users to actively access the well-known SSID by carrying a well-known SSID (such as CMCC, airport, etc.) in the broadcast BEACON frame. The specific scheme is as follows:

(1) AP carries a well-known SSID (such as CMCC, airport, etc.) in BEACON;

(2) The user's wireless terminal actively connects to a well-known SSID through PROBEREQUEST according to historical access information (here it is assumed that the user has accessed the SSID before);

(3) The AP receives the PROBE REQUEST from the wireless terminal, performs self-configuration of the SSID service according to the SSID in the PROBEREQUEST, and provides the wireless access service of the SSID; and responds to the PROBE RESPONSE to the wireless terminal;

(4) The wireless terminal normally accesses the well-known SSID;

(5) The AP cooperates with the corresponding push server to push the message to the wireless terminal.

The AP can also periodically perform self-configured SSID service access statistics, and perform aging deletion on SSIDs that have not been accessed for a long time.
