The platform adopts a microservice architecture, supports virtualization deployment, has strong scalability, and supports multi-domain isolation, multi-tenant sharing, and high resource utilization. Each customer can provide an independent use space, which is isolated from each other and does not affect their respective use, meeting operational needs.

[0035] The core part of the entire system is deployed in the cloud, providing a core platform for core switching and business implementation. It integrates multiple service modules such as IPPBX, SBC, address book, recording, billing, resource management, and automated operation and maintenance. It provides enterprise users with IPPBX business functions such as internal voice communication through cloud SAAS (Software as a Service), and customizes the industry's characteristic businesses to facilitate the rapid implementation of industry needs. Centralized deployment and centralized operation and maintenance in the cloud. Avoid problems caused by limited personnel level of grassroots organizations, and save maintenance and management costs. The Cloud PBX platform fully supports the access of the entire series of IP phones, IP video phones, converged gateways, attendant consoles, PBXs, and IADs to meet the flexible networking needs of different users.

[0036] The system architecture of Cloud PBX is divided into five levels: Figure 2 As shown, different services can be flexibly provided: manage: Provide web services to manage IPPBX; Business layer: BasicAS: service analysis and processing, external call routing, etc. I-SBC: Registration relay edge session controller, providing registration function to other switching networks; User Data: CDB: Central database, providing MySQL and Redis database services, storing user and configuration data.

[0037] DNS: Provides DNS query services for network elements and has certain load balancing functions; MRFS: Provides a distributed file system to manage recording and playback files; Session Control: MS: media server, performs media-related processing; CSCF: accepts and forwards registration, call and other requests; Access and bearer: SBC: accepts and forwards registration and call requests, hiding the network topology of IPPBX from users; Extension modules: OMS operation and maintenance management component: unified status monitoring and business management portal; BAS business activation component: used to connect with external business systems (such as asset management, BOSS) to realize the automatic activation of account business; CDRS call record management component: adopts B / S architecture to realize functions such as call record management, centralized billing, authority control, and business statistics.

[0038] In some embodiments, the cloud PBX platform includes multiple servers, and the multiple servers are distributedly deployed through the nacos middleware.

[0039] In some embodiments, multiple servers are called through Feign components and deconstructed through message queues.

[0040] In some embodiments, the IP intercom and integrated scheduling platform 101 is connected to the integrated communication system platform 102 via an intranet.

[0041] In some embodiments, the desktop video terminal 103 and the converged communication system platform 102 are both connected to the vehicle terminal 104 and the command terminal 105 through the firewall 106 .

[0042] like Figure 3 As shown, the technical route of the emergency command and dispatch system based on multi-source fusion communication provided by the present invention is as follows: 1) Registration Center: The microservices of the Spring Cloud Alibaba Nacos business system are uniformly registered to the Nacos registration center for unified management, and the registration center monitors the service status.

[0043] 2) Gateway: Spring Cloud GateWay unified gateway interception prevents direct exposure of internal microservices and performs authentication at the gateway layer.

[0044] 3) Circuit breaker and current limiting: Spring Cloud Alibaba Sentinel uses Sentinel to control traffic and reduce unstable resources in the call link.

[0045] 4) Distributed transactions: Spring Cloud Alibaba Seata uses Seata to perform distributed transaction processing across service calls.

[0046] 5) Service call: OpenFeign uses OpenFeign for cross-service calls.

[0047] Authentication and authorization: Spring Security + OAuth2.0 OAuth2 is actually a network standard for authorization. Spring Cloud follows the OAuth2 standard and combines a specific implementation of spring-security encapsulation, which is mainly used for user authentication and authorization.

[0048] like Figure 4 As shown, the implementation of the emergency command and dispatch system based on multi-source fusion communication provided by the present invention is as follows: (1) Presentation layer: The content of the presentation layer is mainly the information presentation of the user terminal (computer terminal, APP application, large screen). The information communication between the client and the server is initiated by the http protocol, the Websocket protocol solves the problem of full-duplex communication between the server and the client, and the Web service of the REST design style mode is used to process the resource information of the terminal user.

[0049] (2) Session layer: The content of the session layer mainly reflects the request link path from the user terminal to the corresponding resource service. The user terminal initiates a resource request through the nginx reverse proxy to maintain the session, and then forwards the service through the Spring Cloud Gateway gateway to achieve the comprehensive use of gateway functions such as service fuse, service flow control, permission authentication, and node upgrade trial operation.

[0050] (3) Business layer: The business layer is mainly a microservice architecture model based on the springboot development framework, which mainly includes functional modules such as service bus, inter-service communication, and service / system governance.

[0051] The service bus is a service center formed by distributed deployment of nacos middleware, which integrates and registers the services of various application businesses so that each business application's own client and other related business applications can call services.

[0052] Communication between services is achieved by actively and timely calling services through Feign, and by using message queues (RabbitMQ, Kafka) to help deconstruct business systems and improve development efficiency and system stability.

[0053] The functions of service / system governance are mainly to manage services (Admin Server, Turbine), circuit breaker flow control and service link tracking (Hystrix, ZipKin, Sleuth), log collection management, analysis and query (FileBeat, ELK, Elasticsearch) and server (Zabbix) application monitoring.

[0054] (4) Data layer: The data layer content mainly involves two modes: cache data storage (Redis) and persistent data storage (Mysql, Oracle, Hbase, Hive).

[0055] Redis is mainly used to store some hot data in Redis. When needed, it can be directly retrieved from the memory, which greatly improves the speed and saves server overhead.

[0056] Relational databases such as Mysql and Oracle are mainly used for information storage in various business systems; HBase and Hive are used in big data centers. Hbase is a database suitable for storing unstructured data, mainly solving real-time data query problems. Hive is used for data extraction, transformation, and loading, mainly solving data processing and computing problems.

[0057] (5) Continuous Integration: Continuous integration is a software development practice that verifies integration errors through automated builds (including compilation, release, and automated testing). It is mainly used for continuous and automatic build / testing of software projects. Jenkin is an open source continuous integration (CI) tool that provides a user-friendly interface. Docker allows developers to package their applications and dependent packages into a lightweight, portable container, and then publish it to any popular Linux machine, and can also achieve virtualization.

[0058] Those skilled in the art will appreciate that all or part of the processes of the above-mentioned embodiments can be implemented by instructing related hardware through a computer program, and the program can be stored in a computer-readable storage medium, wherein the computer-readable storage medium is a disk, an optical disk, a read-only storage memory, or a random access memory, etc.
