Abstract

Disclosed are a method and apparatus for controlling the access of a household appliance device to a network. The method includes grouping network configuration information according to a grouping rule; generating a data block of each group, and the data block of each group contains a data packet corresponding to characters on each of information bits of a current group and a data packet corresponding to a serial number, and the length of the data packet corresponds to the characters on one information bit, or corresponds to the serial number, and sequentially broadcasting the data packet in each data block according to a grouping order. Moreover, the efficiency of the household appliance device accessing the network can be improved.

First claim

What is claimed is:

1. A method for controlling access to a network by a household appliance, comprising:
grouping network configuration information into a plurality of groups according to a grouping rule;
generating a data block for each of the plurality of groups, wherein the data block for each of the plurality of groups comprises a first data packet corresponding to a character for each information bit in a current group and a second data packet corresponding to a series number for the current group, a length of the first data packet corresponds to the character for each information bit in the current group, and a length of the second data packet corresponds to the series number for the current group; and
broadcasting data packets in order in each data block according to a grouping order, wherein the household appliance acquires the network configuration information according to the data packets received and accesses the network through the network configuration information.

2. The method according to claim 1 , wherein the information bit is an information bit of a network identifier SSID or an information bit of a password for accessing the network.

3. The method according to claim 1 , wherein generating a data block for each group comprises:
determining the length of the first data packet corresponding to the character for each information bit in the current group according to a pre-stored correspondence between a length and a character, and generating the first data packet with the length determined;
assigning a unique series number to the current group and generating the second data packet with the length corresponding to the series number; and
generating the data block for the current group according to the first data packet corresponding to the character and the second data packet corresponding to the series number.

4. The method according to claim 1 , wherein the data block for each group consists of a preamble field, a length field, a grouping series number field, a content field and a verification field, wherein the preamble field is configured to store specific information, wherein the specific information is pre-arranged between a mobile terminal and the household appliance such that the household appliance locks onto a communication channel through the specific information; the length field is configured to store a length of a network identifier SSID or a length of a password for accessing the network; the grouping series number field is configured to store a grouping series number; the content field is configured to store the character for each information bit in each group; and the verification field is configured to store a verification value, wherein the verification value is generated according to a content of the length field, a content of the grouping series number field and a content of the content field.

5. The method according to claim 4 , further comprising:
determining a length of the network configuration information,
wherein generating a data block for each group comprises:
generating a data packet corresponding to the specific information;
generating a data packet corresponding to the length of the network configuration information;
generating a verification value of the current group according to the character for each information bit in the current group, the length of the network configuration information and the series number for the current group, and generating a data packet corresponding to the verification value; and
generating the data block for the current group according to the data packet corresponding to the specific information, the data packet corresponding to the length of the network configuration information, the data packet corresponding to the series number, the data packet corresponding to the character for each information bit in the current group and the data packet corresponding to the verification value.

6. The method according to claim 4 , wherein the data block further comprises a data packet indicating whether the current group is the network identifier SSID or the password for accessing the network.

7. The method according to claim 1 , further comprising:
receiving a confirmation instruction sent by the household appliance, and stopping sending data packets to the household appliance according to the confirmation instruction.

8. A method for controlling access to a network by a household appliance, comprising:
receiving a sequence of data packets sent by a mobile terminal;
analyzing the sequence of data packets received to determine each data block according to the sequence of data packets received when determining that the sequence of data packets received comprises network configuration information, wherein each of the data blocks comprises a part content of the network configuration information, and each of the data blocks has an individual series number;
receiving the sequence of data packets sent by the mobile terminal continuously when monitoring that there is an incorrect data block having an incorrect content in the sequence of data packets received, and generating the network configuration information according to an order of the series numbers and contents of correct data blocks when determining that all of the data blocks are the correct data blocks each having a correct content according to a plurality of received results; and
accessing a router device based on the network configuration information.

9. The method according to claim 8 , wherein determining that the sequence of data packets received comprises network configuration information comprises:
judging whether the sequence of data packets received comprises data packets satisfying a preset condition; if yes, determining that the sequence of data packets received comprises the network configuration information.

10. The method according to claim 8 , wherein when determining that all of the data blocks are correct and each data block has a correct content according to a plurality of received results, the method further comprises:
sending a confirmation instruction to the mobile terminal, so that the mobile terminal stops sending data packets to the household appliance according to the confirmation instruction.
