When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 1A is a flow diagram illustrating a method of network connectivity in accordance with an exemplary embodiment, and FIG. 1B is a diagram illustrating a scenario of a method of network connectivity in accordance with an exemplary embodiment; the network connection method can be applied to a terminal, and the terminal in the disclosure may be any intelligent terminal having an internet access function, for example, a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), and the like.
The terminal can access the router through the wireless local area network and access the server on the public network through the router. As shown in fig. 1A, the network connection method includes the following steps 101-102:
in step 101, a wireless management frame carrying state information of a three-layer network is received.
In the embodiment of the disclosure, when entering an area with a network, a terminal receives a wireless management frame broadcast by a router, where the wireless management frame carries state information of a three-layer network.
The three-layer network state information comes from the IP application layer, and may at least include: whether a network is available, the number of devices accessing the network, average delay information for completing a specified service, etc. are used for information indicating the state of the three-layer network.
In step 102, a network to be accessed is determined based on three-layer network state information.
In the embodiment of the disclosure, the terminal may determine whether to access the network or select a network to be accessed based on the three-layer network information.
For example, in one embodiment, a terminal may access a network in three-tier network state information when the network is available; when the network in the three-layer network state information is unavailable, the terminal cannot access the network and can select other networks.
In another embodiment, when the number of access networks is more than one, the network to be accessed may be selected based on the number of devices accessing the network, the smaller the number of devices accessing the network, the better the network quality; similarly, the larger the number of devices accessing the network, the worse the network quality.
In another embodiment, when the average delay information for completing the specified service is lower than a set threshold, the corresponding network may be determined as the network to be accessed, and the shorter the average delay, the better the network quality is; similarly, the longer the average delay, the worse the network quality.
In one embodiment, the three-layer network state information may be present in a radio management frame as a bearer in the form of a Vendor-defined IE, in which the Identification (ID) of the Vendor IE may be 221.
In one embodiment, the OUI (organization unique identifier) of the Vendor IE can BE represented by 8C: BE, the OUI type can BE represented by 2, and the OUI type can BE 2 for the IE (Information Element) representing the SSID link status.
In one embodiment, the CONTEXT portion of BE is represented by a plurality of fields, each using TLV (TYPE, LENGTH, VALUE, TYPE, LENGTH, and VALUE) format, one field representing a link state. For TYPE, for example, TYPE ═ 1 indicates whether the device can access internet (i.e., whether a network is available, TYPE ═ 2 indicates the number of devices currently accessing the network in the network, TYPE ═ 3 indicates an average delay time for completing a certain specified service, and the like, where the specified service may be a network game, a network payment transaction, a network short message, and the like. The LENGTH is variable, and represents the LENGTH of VALUE, and can be extended according to actual needs, for example, LENGTH 1 can represent the LENGTH of 1 byte. For VALUE, a specific numerical VALUE is shown.
In an exemplary scenario, as shown in fig. 1B, taking an example that a terminal is in a network with three SSIDs as an example, in the scenario shown in fig. 1B, the method includes: the system comprises a smart phone as a terminal and a routing device. When the smart phone enters a network coverage area with SSID 10, SSID 20 and SSID 30, a wireless management frame broadcasted by the routing equipment is received, the smart phone analyzes the wireless management frame to obtain a network state identifier in the wireless management frame, the network state identifier is used for representing a three-layer network state, and when the network state identifier represents that the three-layer network state of SSID 10 is available, the terminal accesses a network corresponding to the SSID 10.
Please refer to the following embodiments for details of how to perform network connection.
Therefore, the method provided by the embodiment of the present disclosure enables the terminal to select the network to be accessed through the wireless management frame carrying the three-layer network state information sent by the router, thereby avoiding the situation that the network to be accessed is selected only according to the two-layer network state in the related art, which may cause network unavailability, and the like, helping the terminal to find the best network access point, and realizing accurate and fast network connection.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.

in step 201, the wireless management frame is parsed to obtain two-layer network state information.
In the embodiment of the present disclosure, the wireless management frame not only carries the state information of the three-layer network, but also carries the state information of the two-layer network.
The two-layer network state information may include: network Qos (Quality of Service), security information, channel information, bandwidth information, packet loss rate, delay rate, and other information used to represent the status of the two-layer link.
In step 202, a network to be accessed is determined based on the two-layer network state information and the three-layer network state information.
In the embodiment of the disclosure, the terminal selects a network to be accessed by combining the two-layer network state and the three-layer network state.
For example, for a call scenario, where a high latency low bandwidth network state is required, the terminal may select a fully encrypted WPA2(Wi-Fi Protected Access) in combination with the two-tier network state and the three-tier network state.
In one embodiment, the two-layer network status information may also be present in the radio management frame in the form of a Vendor IE. In conjunction with the embodiment shown in fig. 1A, for example, the network QoS is represented by TYPE-4, the security information is represented by TYPE-5, and the like.
In this embodiment, the terminal may carry the three-layer network state information and the two-layer network state information in a wireless management frame and send the wireless management frame to the terminal, so that the terminal selects a network to be accessed based on the two-layer network state information and the three-layer network state information, thereby facilitating selection of an optimal network suitable for a current scenario when the terminal accesses a multi-SSID environment, and improving a success rate of accessing the network.

In another embodiment, when the number of access networks is more than one, the network to be accessed may be selected based on the number of devices accessing the network, the smaller the number of devices accessing the network, the better the network quality; similarly, the larger the number of devices accessing the network, the worse the network quality.
In another embodiment, when the average delay information for completing the specified service is lower than a set threshold, the corresponding network may be determined as the network to be accessed, and the shorter the average delay, the better the network quality is; similarly, the longer the average delay, the worse the network quality.
In one embodiment, the three-layer network state information may be present in a radio management frame as a bearer in the form of a Vendor-defined IE, in which the Identification (ID) of the Vendor IE may be 221.
In one embodiment, the OUI of the Vendor IE may BE represented by 8C: BE, OUI type may BE represented by 2, and OUI type ═ 2 is used for the IE representing SSID link status.
In one embodiment, the CONTEXT portion of BE is represented by a plurality of fields, each using TLV (TYPE, LENGTH, VALUE, TYPE, LENGTH, and VALUE) format, one field representing a link state. For TYPE, for example, TYPE ═ 1 indicates whether the device can access the internet, i.e., whether the network is available, TYPE ═ 2 indicates the number of devices in the network that have currently accessed the network, TYPE ═ 3 indicates an average delay time for completing a certain specified service, and the like, where the specified service may be a network game, a network payment transaction, a network short message, and the like. The LENGTH is variable, and represents the LENGTH of VALUE, and can be extended according to actual needs, for example, LENGTH 1 can represent the LENGTH of 1 byte. For VALUE, a specific numerical VALUE is shown.
In this embodiment, through the steps 301 and 302, the router can send the wireless management frame carrying the information of the three-layer network state to the terminal, so that the terminal can select the network to be accessed according to the three-layer network state, thereby avoiding the situation that the network to be accessed is selected only according to the two-layer network state in the related art, which may cause network unavailability, and helping the terminal to find the best network access point, thereby implementing accurate and fast network connection.
In another embodiment, the routing device may further carry the two-layer network state information and the three-layer network state information in a wireless management frame, and broadcast the wireless management frame to the terminal, so that the terminal determines a network to be accessed based on the two-layer network state information and the three-layer network state information.
Therefore, the routing equipment sends the wireless management frame carrying the two-layer network state information and the three-layer network state information to the terminal, so that the terminal can determine the network to be accessed by combining the two-layer network state and the three-layer network state, and the optimal network most suitable for the current scene can be selected.
