Method, apparatus and system for network connection, and server and medium

A server for providing updated network connection credentials via a preset backup communication channel to a mobile robot, the server comprising:

• one or more processors;
• and
• a memory, storing one or more programs,
• wherein the one or more programs, when executed by a processor, cause the processor to perform operations, the operations comprising:
• sending, in response to determining that there is a first target mobile terminal arriving at a preset network alternating area, an updated network credential of a first target network to the first target mobile terminal using a preset spare connection mode,
• wherein the first target mobile terminal comprises the mobile robot,
• wherein the preset network alternating area comprises a junction area between two areas within coverage ranges of different networks,
• the different networks respectively require different network credentials for access,
• the different networks comprise the first target network and a second network, wherein the first target network comprises a network area to which the first target mobile terminal connects after crossing the preset network alternating area, and
• the preset spare connection mode refers to a wireless communication technique other than that provided by a connection to the first target network and other than that provided by a connection to the second network, wherein the preset spare connection mode comprises using a long range radio (LoRa) for sending the updated network credential;
• receiving a connection request for connecting to the first target network that is sent by the first target mobile terminal;
• and
• establishing the connection of the first target network with the first target mobile terminal, in response to verifying that the connection request for the first target network matches the updated network credential of the first target network.

A system for transmitting a network connection credential for a target Wi-Fi network via a preset backup communication channel to a mobile robot roaming between network coverage areas, the system comprising:

• a server side and a mobile terminal comprising the mobile robot, wherein
• the server side is configured to:
• broadcast using a Long Range Radio (LoRa) as a preset spare connection mode a network credential of the target WiFi network to the mobile terminal in response to determining, based on at least one of received location data of the mobile terminal and a motion path of the mobile terminal, that the mobile terminal is arriving from a coverage area of a first WiFi network at a preset network alternating area, wherein the preset network alternating area comprises a junction area between two areas within coverage ranges of different networks which comprise the target WiFi network and the first WiFi network, each of which uses respectively different network credentials for access,
• wherein the target WiFi network comprises a network area to which the mobile terminal will be connected to after crossing the preset network alternating area,
• receive a connection request for the target WiFi network that is sent by the mobile terminal;
• and establish the connection of the target WiFi network with the mobile terminal, in response to verifying that the connection request for the target network matches the network credential of the target WiFi network;
• and
• the mobile terminal is configured to receive using a first long range radio (LoRa) transmission terminal, a network credential using the preset spare connection mode, and after receipt send a connection request based on the received network credential for the target WiFi network to the server side.
