Example 2
The invention provides a wireless network management method for a broadband wireless network management system based on a TR069 protocol in embodiment 1, which comprises the following steps:
the HTTP Server node establishes HTTP connection with the AP terminal to acquire an Inform message, a GetParameterValues message and a SetParameterValues message of a TR069 protocol;
the HTTP Server node sends the Inform message, the GetParameterValues message and the SetParameterValues message to the InfoServer node, the GetParamServer node and the SetParamServer node respectively for message processing, so as to respond to triggering:

In this embodiment, as shown in fig. 3, a flow of implementing the Inform message processing by the broadband wireless network management system based on the TR069 protocol provided by the embodiment of the present invention is specifically as follows:
step 101, the AP terminal initiates an HTTP request to the HTTPServer node and establishes HTTP connection with the HTTPServer node.
102, the AP terminal initiates an Inform Request to the HTTPServer node, wherein the Inform Request consists of a field < cwmp: Inform >, the field < cwmp: Inform > comprises information such as a terminal manufacturer and a terminal ID, the terminal ID is globally unique, and different terminals have different terminal IDs.
Specifically, an AP terminal initiates an Inform Request to an HTTPServer node, a ProtocoHandler processes the Inform Request by rewriting a handleInterntenal method, firstly calls an Xstream library to analyze a < soap: Envelope > message of the Inform Request to obtain a < cwmp: info > field, and then analyzes subfields < Manufacter > and < SerialNumber > in the < cwmp: info > field, wherein the subfields < Manufacter > is the name of the AP terminal provider, and the < SerialNumber > is the ID information of the AP terminal. The AP terminal ID is globally unique, and different AP terminals have different terminal IDs.
And 103, the HTTPServer node receives the Inform Request, analyzes < cwmp: Inform >, obtains the terminal ID, and then creates a hash table H to record the Session context of the connection between the terminal ID and the HTTP.
Specifically, the http server creates a hash table H, and the hash table H records a correspondence between an http context parameter of the handlelnternal method and an AP terminal ID, where the AP terminal ID is a primary key and the http context parameter is a corresponding value. The hash table H can be represented as:
[<APID_1,HttpContext_1>,<APID_2,HttpContext_2>,…,<APID_N,HttpContext_N>]。
step 104, the HTTPServer node initiates a service discovery request to the Zookeeper node, reads a root node on the Zookeeper, obtains IP and port information of the InformServer node, then initiates RPC connection to the InformServer node, and sends a < cwmp: Inform > field to the InformServer node.
And 105, the InformServer node receives the < cwmp: Inform > field, analyzes the terminal ID from the < cwmp: Inform > field, then creates a state table S and records that the terminal ID is in an on-line state.
Specifically, the InformServer node receives a < cwmp: Inform > field, parses < Manufacturer > and < SerialNumber > subfields from the < cwmp: Inform > field, and creates a state table S. The state table S is a hash structure and is used for recording the current state of the AP terminal, and the value range of the current state staus is ("online" or "offline"), where online represents online and offline represents offline.
The primary key of the state table S is the AP terminal ID, and the corresponding value is status. The state table S can be expressed as:
[<APID_1,status_1>,<APID_2,status_2>,…,<APID_N,status_N>]。
the InformServer node inserts an element into the state table S, and the element stores the state corresponding to the AP terminal ID as "online".
And step 106, the InformServer node creates an Inform operation response message which is a field < cwmp: InformResponse >, and the InformServer node returns the field to the HTTPServer node.
Step 107, the HTTPServer node receives the < cwmp: Inform Response > field, encapsulates it into an Inform Response message, and then sends the message to the AP terminal.
And 108, initiating a service discovery request to the Zookeeper node by the InformServer node, reading a root node on the Zookeeper node, acquiring IP and port information of the WebServer node, then initiating a WebSocket request to the WebServer node, and establishing a bidirectional path.
Step 109, the http server node encapsulates the AP terminal ID and the corresponding status into a message in JSON format, sends the message to the WebServer node, and the WebServer node parses the received JSON message and displays the AP terminal ID and the corresponding status on a page.
As shown in fig. 4, the steps of implementing the GetParameterValues message operation by the broadband wireless network management system based on the TR069 protocol provided by the embodiment of the present invention are specifically as follows:
step 201, the HTTPServer node calls an httpcore library to start an HTTP server, creates a ProtocolHandler thread to monitor an HTTP request at a specified port, and waits for an AP terminal to initiate HTTP connection.
Step 202, the AP terminal initiates an HTTP request to the HTTP server node, and establishes an HTTP connection with the HTTP server node.
Step 203, the GetParamServer node initiates connection to the Zookeeper node, reads a root node on the Zookeeper node, obtains IP and port information of the WebServer node, and then initiates a WebSocket request to the WebServer node to establish a bidirectional path.
Step 204, the WebServer node issues an AP terminal read operation request to the GetParamServer node, where the request is in JSON format and can be expressed as:
[ AP terminal ID, Paramname1, Paramname2, …, ParamnameN ].
Step 205, the GetParamServer node receives the AP terminal read operation request:
[ AP terminal ID, Paramname1, Paramname2, …, ParamnameN ],
resolving an AP terminal ID and a parameter list:
[ParamName1,ParamName2，…,ParamNameN]。
and step 206, initiating connection to the Zookeeper node by the GetParamServer node, reading a root node on the Zookeeper node, and acquiring the IP and port information of the InfoServer node.
Step 207, the GetParamServer node initiates RPC connection to the InfoServer node, and sends the parameter "AP terminal ID". The InfoServer traverses the state table S and searches for the key as the element of the ID of the AP terminal.
And if the corresponding element is found and the value of the element is 'online', which indicates that the AP terminal is online, returning the information of 'AP terminal is online' to the GetParam Server.
Step 208, the GetParamServer node receives the information of "AP terminal is online" returned by the InfoServer node, creates < ParameterNames > field and < ID > field, encapsulates the parameter list [ ParamName1, ParamName2, …, ParamName n ] into < ParameterNames > field, creates < cwmp: GetParameterValues > field, inserts < ParameterNames > field into < cwmp: GetParameterValues > field, finally encapsulates the AP terminal ID into < ID > field, and inserts ID field into < cwmp: GetParameterValues > field.
Step 209, the GetParamServer node initiates connection to the Zookeeper node, reads the root node on the Zookeeper node, obtains the IP and port information of the HTTPServer node, then initiates an RPC request to the HTTPServer node, and sends the < cwmp: GetParameterValues > field to the HTTPServer node.
Step 210, the HTTPServer node parses the received < cwmp: GetParameterValues > field, parses out the AP terminal ID, deletes the < ID > field from the < cwmp: GetParameterValues > field, and then queries the hash table H through the AP terminal ID:
[<APID_1,HttpContext_1>,<APID_2,HttpContext_2>,…,
<APID_N,HttpContext_N>]；
and obtaining the HTTP Session context corresponding to the AP terminal ID.
And step 211, the HTTPServer node creates a < soap: Envelope > message, inserts a < cwmp: GetParameterValues > field into the < soap: Envelope > message, creates a < soap: Header > message, encapsulates the AP terminal ID into the < soap: Header > message, and finally sends the < soap: Envelope > message to the AP terminal corresponding to the terminal ID through the HTTP Session context.
Step 212, the AP terminal corresponding to the terminal ID receives the message < soap: Envelope >, parses the message < soap: Envelope >, reads the < cwmp: GetParameterValues > field in the message to obtain a parameter list, and then executes the read operation command according to the parameter list to generate a state list.
And then, encapsulating the state list into a < cwmp: GetParameterValueResponse > field, encapsulating the field into a < soap: Envelope > message, and finally returning the message to the HTTPServer node.
Step 213, the HTTPServer node receives the message of < soap: Envelope >, resolves the field of < cwmp: GetParameterValuesResponse >, and returns the field to the GetParamServer node.
Step 214, the GetParamServer node receives the < cwmp: GetParameterValuesResponse > field, parses the < ParameterList > and further parses the < ParameterList > sub-field < ParameterValueStruct >, and then parses the parameter list and the corresponding state list from the < ParameterValueStruct > sub-field.
Step 215, the GetParamServer node encapsulates the parameter list and the corresponding state list into JSON data, and sends the data to the WebServer node through the WebSocket channel.
And step 216, the WebServer node analyzes the received JSON data and displays the parameter list and the corresponding state list on the webpage.
As shown in fig. 5, the steps of implementing the SetParameterValues message operation by the broadband wireless network management system based on the TR069 protocol provided by the present invention are specifically as follows:
step 301, the HTTPServer node calls an httpcore library to start an HTTP server, creates a ProtocolHandler thread to monitor an HTTP request at a specified port, and waits for an AP terminal to initiate HTTP connection.
Step 302, the AP terminal initiates an HTTP request to the HTTPServer node and establishes HTTP connection with the HTTPServer node.
Step 303, the SetParamServer node initiates connection to the Zookeeper node, reads a root node on the Zookeeper node, obtains IP and port information of the WebServer node, and then initiates a WebSocket request to the WebServer node to establish a bidirectional path.
Step 304, the WebServer node issues an AP terminal write operation request to the SetParamServer node, where the request is in JSON format and can be expressed as:
[ AP terminal ID, [ ParamName1, ParamValue1], [ ParamName2, ParamValue2] …,
[ParamNameN,ParamValueN]。
step 305, the SetParamServer node receives the AP terminal write operation request:
[ AP terminal ID, [ ParamName1, ParamValue1], [ ParamName2, ParamValue2] …,
[ParamNameN,ParamValueN]；
the AP terminal ID and the parameter list [ [ ParamName1, ParamValue1], [ ParamName2, ParamValue2] …, [ ParamNameN, ParamValueN ] ] ] are analyzed.
Step 306, the SetParamServer node initiates connection to the Zookeeper node, reads a root node on the Zookeeper node, and obtains the IP and port information of the InfoServer node.
Step 307, the SetParamServer node initiates an RPC connection to the InfoServer node, and sends a parameter "AP terminal ID".
The Inform Server traverses the state table S, searches for an element with a key as the ID of the AP terminal, and returns information of 'AP terminal is online' to the SetParam Server if a corresponding element is found and the value of the element is 'online', which indicates that the AP terminal is online.
Step 308, the SetParamServer node receives the information that the AP terminal returned by the InfoServer node is online, creates a < parametervaluestart > field and a < ID > field, and lists the parameters:
[[ParamName1,ParamValue1],[ParamName2,ParamValue2]…,[ParamNameN,Param ValueN]]
packaging into the < ParameteValueStatc > field, creating the < ParameteList > field, and inserting the < ParameteValueStatc > field into the < ParameteList > field;
then create < cwmp: SetParameterValues > field and insert < ParameterList > field into < cwmp: SetParameterValues > field;
finally, the AP terminal ID is encapsulated into the < ID > field and the ID field is inserted into the < cwmp: SetParameterValues > field.
Step 309, the SetParamServer node initiates connection to the Zookeeper node, reads the "root" node on the Zookeeper node, obtains the IP and port information of the HTTPServer node, then initiates an RPC request to the HTTPServer node, and sends the < cwmp: SetParameterValues > field to the HTTPServer node.
Step 310, the HTTPServer node analyzes the received < cwmp: SetParameterValues > field, analyzes the AP terminal ID, deletes the < ID > field from the < cwmp: SetParameterValues > field, and then queries the hash table H through the AP terminal ID:
[<APID_1,HttpContext_1>,<APID_2,HttpContext_2>,…,
<APID_N,HttpContext_N>]；
and obtaining the HTTPSession context corresponding to the AP terminal ID.
Step 311, the HTTPServer node creates a message of < soap: Envelope >, and inserts the field of < cwmp: SetParameterValues > into the message of < soap: Envelope >.
Then, a < soap: Header > message is created, and the AP terminal ID is packaged into the < soap: Header > message.
And finally, transmitting the < soap: Envelope > message to the AP terminal corresponding to the terminal ID through the HTTP Session context.
Step 312, the AP terminal corresponding to the terminal ID receives the message < soap: Envelope >, parses the message < soap: Envelope >, reads the < cwmp: SetParameterValues > field in the message, and obtains a parameter list:
[[ParamName1,ParamValue1],[ParamName2,ParamValue2]…,[ParamNameN,P aramValueN]]；
then executing a write operation command according to the parameter list, then creating a < cwmp: SetParameterValueResponse > field, and saving a write operation result into a sub-field < status > of the < cwmp: SetParameterValueResponse > field;
and then encapsulating the < cwmp: SetParameterValueResponse > field into a < soap: Enterope > message, and returning the message to the HTTPServer node.
Step 313, the HTTPServer node receives the message of < soap: Envelope >, resolves the field of < cwmp: SetParameterValuesResponse >, and returns the field to the SetParamServer node.
In step 314, the SetParamServer node receives the < cwmp: SetParameterValuesResponse > field, parses the < status > field, and the value of the field indicates the result of the write operation.
And 315, encapsulating the AP terminal ID and the < status > field into JSON data by the SetParamServer node, and sending the data to the WebServer node through the WebSocket channel.
And step 316, the WebServer node analyzes the received JSON data and displays the write operation result on a webpage.
