The Kafka service mainly solves the problems of parameter configuration and instruction issuing under the condition that an access terminal at an IMS core side is not registered or is disconnected. After the core network finishes all network element operation requests, the interface service adapter analyzes a return result, one or more configuration requests are formed according to service interface numbers to send instructions to the appointed access side equipment, all the instructions are sequentially put into a message queue, a first instruction in the message queue is taken out and then is requested to a target terminal through an HttpUrlconnection, and if the target terminal is dropped or is not registered, the instructions are put into queue again; and if the target terminal is registered, the command is dequeued, and the terminal equipment is issued.
It should be noted that the B/S architecture relates to HTTP request, HTTP connection, which is a way of requesting through HTTP protocol.
URLConnection is an abstract class that has two direct subclasses, HttpURLConnection and JarURLConnection, respectively. Another important class is URLs, which can be passed to the constructor to generate an instance of a URL pointing to a particular address, typically with a String type parameter.
Each HTTP connection instance may be used to generate a single request, but other instances may transparently share the underlying network connected to the HTTP server. Invoking the close () method on InputStream or OutputStream of HttpURLCONNECTION upon request may free the network resource associated with this instance, but without any impact on the shared persistent connection. If the persistent connection is idle when disconnect () is called, the base socket may be closed.

The interface service adapter analyzes a service interface of a core network or an access network according to the service record, the core network performs data analysis according to the service interface number to form one or more network element operation requests, encapsulates message instructions according to the network element operation requests, sequentially sends the operation instructions to HSS, ATS and ENS network elements of the IMS core network, analyzes and returns an analysis result. After the core network finishes all network element operation requests, the interface service adapter analyzes the returned result, forms one or more configuration requests according to the service interface number to send an instruction to the appointed access side equipment, analyzes the returned response, and finally forms a uniform response result to be returned to the front-end controller (IMSAdmin). And the front-end controller (IMSAdmin) records the returned result and the service keyword to the database server and displays the final result description of the service configuration to the user. The browser that is presented to the user via the HTTP Response is presented to the end user. The configuration automatic issuing of each network element of the IMS core network and each access device (IAD device and IP telephone) of the IMS access network is completed through the operation of page.
In view of the problem of timeliness of installation of access network equipment, a Kafka message queue mechanism is provided, a dequeue instruction can be executed under the condition that the equipment which has accessed the network can be connected through the network, the access equipment which is not powered on and does not access the network can be subjected to losing and then is subjected to dequeue again after the dequeue execution fails, and the instruction FIFO is issued after the network is connected through the dequeue.
(all instructions enqueue, after taking out the instructions in the queue, request the target address through HttpUrlconnection, if the target is not reachable, the instructions are enqueued again, otherwise, the instructions are dequeued, the configuration is executed and the instructions are issued.)
The Nginx soft load in the HTTP server communicates with the application server in an HTTP forwarding manner. The HTTP server A, B node uses keepalive to complete the mutual backup disaster recovery in a socket manner.
