As shown in fig. 3, the system mainly includes: the system comprises a fault home gateway HGW WiFi module (located in a home local area), an operation and maintenance public network module of a peripheral home gateway HGW and a diagnosis and analysis module of a cloud management platform.
The main functions of the respective modules are described in detail below to explain the implementation process of the technical solution of the present application.
Failed home gateway HGW WiFi module:
the module is used for sending beacon (beacon) requests containing equipment identification ID information of the failed home gateway HGW to HGWs of peripheral neighbors through WiFi (wireless fidelity) by the module of the failed home gateway HGW under the condition that a home network fails. And after the neighbor HGW monitors the beacon request of the fault equipment, the neighbor HGW automatically responds and is connected with the beacon request, so that the fault message is obtained and forwarded to the cloud management platform.
Operation and maintenance public network module:
the module is based on the surrounding normally-operated home gateway HGW and is used for scanning all channels in the network so as to monitor WiFi connection requests of the surrounding failed home gateway; after the trusted connection request is identified, the trusted connection request is responsible for establishing a WiFi secure encryption channel with the failed gateway; and synchronizing the relevant network configuration parameters (fault information) of the fault gateway; and forwarding the received fault information to a cloud management platform.
A cloud management platform diagnostic analysis module:
the module is responsible for authenticating the equipment identification ID and the connection establishment request; and after the authentication is passed, matching the family user information and the network fault information, and performing further analysis and processing to diagnose the fault existing in the current family wireless network.
A flow diagram of a WiFi-based home network diagnostic method according to an embodiment of the present application is illustrated in fig. 4.
As shown in fig. 4, the WiFi-based home network diagnosis method according to the present application mainly includes the following steps.
Step 1: sending WiFi connection establishment request information to a peripheral HGW by a failed home gateway HGW so as to establish connection with the peripheral HGW;
step 2: the peripheral HGW scans all channels to monitor the connection request of the peripheral failure gateway HGW;
and step 3: the peripheral HGW forwards the connection establishment request information to the cloud management platform;
and 4, step 4: the cloud end management platform authenticates the equipment identification ID and the connection establishment request;
and 5: the cloud management platform returns connection request response information to the peripheral HGW;
step 6: the peripheral HGW returns connection request response information to the failed home gateway HGW;
and 7: establishing safe encrypted connection between the failed home gateway HGW and the peripheral HGW;
and 8: the fault home gateway HGW sends fault information associated with the equipment identification ID to the peripheral HGW;
and step 9: the peripheral HGW forwards the fault information of the faulty home gateway HGW to the cloud management platform;
step 10: the cloud management platform matches the fault information with the family user information; and
step 11: and the cloud end management platform analyzes and processes the fault information to diagnose the fault existing in the faulty home gateway HGW.
As described above, according to the embodiments of the present application, the system and method are based on the whole process of connection establishment request, device identification ID and connection request authentication, secure connection establishment, fault information forwarding, information processing and analysis, and diagnosis of the home gateway via the peripheral home gateway and the cloud management platform.

Compared with the gateway fault diagnosis method and system which are ubiquitous in the prior art, the scheme of the application has the following technical advantages.
Firstly, the existing home client gateway terminal and the cloud management platform adopt a single-point remote access mode, so that when a home gateway breaks down and is disconnected, the relevant information of a home network cannot be reported to the cloud management platform in time for analysis and diagnosis, and only manual home-visit diagnosis can be relied on; according to the method and the system, the home gateway terminal ecology owned by an operator is utilized, the value of the WiFi capability of the home gateway is maximized, the trusted special remote diagnosis WiFi network access is constructed based on the WiFi technology, the fault gateway terminal uploads the fault information to the cloud management platform through the special diagnosis WiFi network access, and the reliability of remote diagnosis is improved.
Secondly, a WiFi-based signaling sending and monitoring mechanism is established between the faulty home gateway and the peripheral reliable home gateways through the peripheral home gateways, so that the network value of the peripheral reliable gateways is maximized;
and thirdly, a special diagnosis WiFi network access is established through the peripheral home gateway and the cloud management platform, so that the cost of manpower for home operation and maintenance is saved, the operation and maintenance efficiency is improved, and the operation and maintenance cost is reduced.
