Step 1002: The chairman that receives the message sends the list of chat sessions maintained by itself, that is, the Chatroomlist, to the node requesting the chat session in the Serach_Chat_Response message.

Here, the chairman may be one or more.

Step 1003: After receiving the message, the node selects a chat session that is desired to join according to the carried Chatroomlist.

Step 1004: The node sends the C-ID of the chat session that you want to join, the Nickname that is added to the chat session, and the U-ID that is used to be carried in the Join_Chat-Request message to the chairman that maintains the chat session.

Step 1005: The chairman that maintains the chat session updates the user list of the chat session corresponding to the C-ID according to the Nickname and U-ID carried in the received message, and sets the user list in the UserList, and carries it in the Join_Chat_ The message is sent to riods.

Correspondingly, the chairman who maintains the chat session also sends the Nickname and U_ID of the client newly added to the user list of the chat session corresponding to the C-ID to other nodes in the user list, so as to inform other nodes that there are new nodes. Join and determine the information of the newly joined node so that the newly joined node can chat with other nodes in the user list.

Step 1006, the other nodes in the chat session have learned the information of the client, and will carry the Nickname of the client, the C-ID of the chat session and the GMessag of the information are sent to the client, and the client will carry the Nickname of the other node, the chat session The C-ID and the GMessag of the information are sent to the corresponding other nodes in the chat session, and the other nodes and the client can chat in the chat session.

This step can continue and last for a while.

Step 1007, the node sends to the chairman who maintains the chat session

The Leave-Chat-Request message carries the U-ID of the joined chat session and is used to leave the chat session that has been joined.

Step 1008: The chairman that maintains the chat session determines a user list of the corresponding chat session according to the U-ID carried in the received message, and updates the user list, that is, deletes Node information (including Nick_Name and U-ID).

Step 1009: Maintain the chairman of the chat session to send a Leave-Chat-Response message to the node, and determine that the node has left the chat session.

Correspondingly, the chairman who maintains the chat session also sends the Nickname and U_ID of the Client deleted in the user list of the chat session corresponding to the C-ID to other nodes in the user list, so as to inform other nodes that they have left. The node also determines the information leaving the node.

In Ad-Hoc mode, it is necessary to switch the chairman. When the chairman wants to leave the maintained chat session, it should specify a node as the chairman to maintain the chat session to be left. The specific method is shown in Figure 11. 11 is a flowchart of a method for switching a chair node in an Ad-Hoc mode according to an embodiment of the present invention. The specific steps are as follows:

Step 1101: The chairman who wants to leave the maintained chat session multicasts a Switch-Authority-Request message in the ZigBee network, and the message may carry a Chatroomlist to leave the chat session or carry a C-ID for querying instead of maintaining the chat session. node.

Step 1102: A node in the ZigBee network responds to the message, and sends a Switch- Chairman_Response message to the cChairman, carrying the U ID, indicating that it is desirable to maintain the chat session instead of the chairman.

In this step, the message may be sent to one or more nodes, and the one or more nodes separately send the message to the chairman.

Step 1103: After the chairman receives at least one message within the set time, select a node to replace himself according to the set rule.

In this step, the set time can be set according to user needs or network conditions. The set rules are set as required, and are not limited here.

Step 1104: The chairman carries the information of the selected node in the Switch_National-Confirm message to all nodes in the chat session group.

In this step, chairman sends the message in multicast mode.

Step 1105, after the selected node receives the message, instead of chairman maintenance The chat session will unicast the Switch- Chairman- Confirm message to the original chairman in the chat session group to be maintained.

Step 1106: After receiving the message, the chairman initiates a process of exiting the chat session to the selected node. The process may refer to steps 1007 to 1009, and is not described here.

In step 1103 in this embodiment, if the chairman does not receive the Switch_Authent_Response message returned by any node within the set time, the chairman may specify in the chat session group according to a preset specified rule. A node acts as an alternate chairman node, initiates a request to its unicast, waits for its consent to designate the node as the chairman node, or in order to quickly switch the chairman, the chairman directly designates a node as the alternate chairman node and directly indicates the handover, replacing the designated node. Maintain a chat session.
