The present invention relates to the field of telecommunication technology, in particular to a hierarchical decoupling, integrated and open communication open system.
A communication network architecture in the related art has low construction efficiency, high maintenance costs, and difficult operation and maintenance. Moreover, communication technology solutions for government and enterprise customers have single function, and a communication access technology mainly has following shortcomings.
For an enterprise customer, it needs to apply for a number resource and a line resource from operators in various regions respectively when accessing an operator communication network, and services cannot be activated nationwide at the same time. Limited by the process complexity of the operators in various regions, approval procedures for the enterprise customer to activate communication services in all of the regions are cumbersome and inefficient.
For an enterprise customer, communication equipment needs to be configured in various cities and accessed to an operator communication network to form networking within the enterprise. In order to ensure that enterprise communication services are available, the enterprise needs to deploy professional communication support personnel in the various cities to provide localized maintenance support, and labor costs of professional communication operation and maintenance remain high.
For an enterprise customer and an operator, in the related art, the customer is accessed to a communication network through an E1 trunk circuit, equipment construction and line connection construction are required for an operator network and a customer system, and an access cycle is generally two to three months. At the same time, when needs for services increase and resource expansion is required, the operator needs to upgrade hardware and expand line capacity in an operator computer room. The data configuration is complex and an iteration cycle is long, and it is impossible to periodically and dynamically allocate resources for the customer according to service peaks of the customer, which greatly affects the service development of the customer.
For an operator, current customer communication access solutions can only provide customers with “dumb pipes”, cannot provide customers with rich value-added applications, and cannot enhance the value of an operator communication network.
For an operator, current customer communication access solutions still have potential risks in information security. User call behaviors cannot be controlled, service content is difficult to control, source tracing is difficult when complaints arise, and there are potential risks in the information security.
It is therefore an object of the present invention to provide a hierarchical decoupling, integrated and open communication open system, which innovates decentralized communication service provision ways, further integrates communication capabilities, encapsulates communication scenarios into flexible and easy-to-use communication modules, and opens a unified and convenient service interface, thereby lowering an user-side access threshold, and allowing deeply integrated communication capabilities with application scenarios of government and enterprise customers.

By making communication capabilities cloud-based and software-based, modules are decoupled from one another and support scaling, the communication stability and the information security are improved. Therefore, a low-threshold communication capability application programming interface (API) or software development kit (SDK) is open to the outside world, and rich scenario-based communication applications are provided and perfectly integrated into customer service systems. Specifically, general-purpose computing hardware such as x86 and ARM and a virtualization technology are used to carry the functions of network equipment in the related art, replace the private, dedicated and closed hardware equipment in the communication network, redefine and construct CT networks, and build a unified and general-purpose hardware platform and service logic open architecture. With software and hardware decoupling and abstraction of a CT network function, a control plane and a data plane of CT network equipment are separated. Therefore, solutions in the related art that are based on dedicated hardware equipment are transformed into more open software-based solutions, so that the CT network function does not depend on the dedicated hardware equipment, giving network resources flexibility and openness while taking into account security. Software is used to replace dedicated NAT, load balancing, session border controller, DNS, firewall and other hardware equipment to provide the same virtual network functions. The sub-functions described above are combined into a virtual router that can handle complex communication services, which can be quickly implemented and applied on a general-purpose hardware server, and can perform automatic deployment, scaling, fault isolation and self-healing according to actual service needs.

The solo figure shows a hierarchical decoupling, integrated and open communication open system according to an embodiment of the present invention, including: a large communication network; a Yunxi platform; and a customer, which are communicatively connected to one another.
In the present embodiment, the Yunxi platform includes a service application layer, a communication capability layer, and a resource pool, which are communicatively connected to one another,

According to the present embodiment, the communication capability layer includes a large network adaptation module, a call route analysis module, a call control module, a charging authentication control module, a data cache module, a data storage module, a large network implementing signaling processing module, a media processing module and a customer connection signaling processing module.
In this situation, the large network adaptation module is communicatively connected to the large network implementing signaling processing module.
The call route analysis module, the call control module, the charging authentication control module, the data cache module and the data storage module are communicatively connected to one another.
The large network implementing signaling processing module, the media processing module, and the customer connection signaling processing module are communicatively connected to one another.
The call route analysis module, the call control module, the charging authentication control module, the data cache module and the data storage module are each communicatively connected to the large network implementing signaling processing module, the media processing module and the customer connection signaling processing module.
Specifically, the call route analysis module is configured to automatically put a call into a call queue for waiting, and then allocate an optimal call path to the call based on established call rules and call relations.
The call control module is used to establish, maintain and clear a call, and complete an operation request from the service application layer by controlling the signaling processing module and the media processing module.
The charging authentication control module is configured for charging authentication of an access request from a user, determining a payment subscription status of the user, and authorizing a communication resource operation request.

The service application layer in the present embodiment particularly includes functions of cloud recording, cloud transcription, cloud quality inspection, cloud business card, cloud positioning, cloud identification, cloud anti-disturb and/or number transfer.
Specifically, the service application layer uses a low-code application programming interface (API) open module to provide a low-code lightweight communication API service to a user, and adopts a pluggable concept to build a loosely coupled plug-in architecture to adapt to flexible and customized development or calling needs. Functions will evolve synchronously with a customer service system while an external interface remains unchanged. In a design stage of API, the pluggable design concept is adopted to build a loosely coupled plug-in architecture and separate extended functions from the overall product design framework. Each plug-in only completes a specific function, and a complex functional service thus is formed through the combination of different plug-ins, thereby reducing the complexity and maintenance difficulty of the framework and adapting to flexible and customized development or calling needs. Specifically, during a test stage of the API, different application programming interface workspaces are preset, different access addresses are assigned to API in the workspaces and a gateway, and the API under test and running is logically isolated to ensure that the data during test does not contaminate the running data. In a management stage of the API, by introducing the concept of API portal, the communication capability API is shared and opened as an IT resource, and resources are isolated and managed at the smallest granularity through an independent tenant model. In a release stage of the API, interactive API documents are used to conduct call evaluation and functional evaluation of the API, so that a set of interface documents can adapt to hundreds of different scenarios and reduce use costs for a consumer of the API.
