With the advance of WTO and the continuous entry of international telecommunication companies, the competition in the domestic telecommunication industry is also becoming fiercer. In the future, the winning rule for telecom operators will no longer be telecom resources, but will increasingly depend on management capabilities supported by IT technology. Therefore, as a powerful weapon to reduce costs, improve efficiency and strengthen the core competitiveness of enterprises, enterprise informatization is an inevitable choice for domestic telecommunications enterprises.

At present, all domestic telecommunications companies will promote enterprise informatization as a strategic measure to enhance their core competitiveness, and constantly improve and optimize business analysis, billing and accounting, customer relationship management and other enterprise information systems. Telecom companies also hope to achieve effective information sharing through the construction of enterprise informatization, realize the production, operation and management process of the enterprise online, realize the operation automation and intelligent decision-making within the enterprise, so as to improve the efficiency of production, operation, management and decision-making and level, improve the service level for customers and the ability to respond quickly to market changes, ultimately improve the economic benefits and core competitiveness of enterprises, and promote the transformation of telecom operators from traditional low-cost resources to comprehensive information service providers.

Most of the IT resource support systems of existing telecom operators are deployed independently, monopolizing IT resources, and the operation is relatively extensive, and there are common problems such as low utilization of equipment resources. From the inside of the IT resource support system, the equipment resources of the existing IT resource support system are difficult to be fully utilized, the operation is extensive, and cross-system resource deployment and scheduling cannot be realized, and it is difficult to be reused. In terms of IT support for external business, each business platform of the existing IT resource support system is built independently, and it is difficult to form the ability of resource sharing and unified business management. There are not enough types of personalized services, and the cost of terminal-oriented adaptation is high. The independent management of infrastructure resources cannot meet the growing demand for rapid launch of new services. Therefore, telecom operators urgently need to realize unified scheduling and flexible allocation of IT resources, optimize scalability and compatibility, realize the separation of software and hardware, integrate resources and platforms, effectively solve the problem of energy saving and consumption reduction, and accelerate the development of value-added products. development and application cycle.

(3) Use Web 2.0, SOAP and other SaaS technologies to transform the existing telecom IT support system to achieve zero installation, zero maintenance and high scalability of various applications.

In the following, a specific IT resource support system architecture method is used to further illustrate the above-mentioned IT resource support system embodiments provided by the present invention. As shown in Figure 7, the architecture methods of the above-mentioned IT resource support system embodiments provided by the present invention can be specifically implemented through the following steps:

Step S1, virtualizing the hardware device into a virtual device;

Step S2, creating a management policy for managing hardware devices and virtual devices;

Step S3, creating a service interface;

Step S4, constructing the resource bottom layer based on the above steps S1 to S3;

Step S5, creating an application service, and constructing a management middle layer based on the created application service;

Step S6, constructing an upper-layer service interaction platform for presenting various application services.

Through the above-mentioned IT resource support system architecture method, an open IT resource support system can be realized, which realizes the unified scheduling and flexible allocation of IT resources, realizes the separation of software and hardware, and integrates resources and platforms, so that the IT resource support system can be quickly and efficiently Flexibly respond to the needs of various business requests.

In specific implementation, the step S1 can use the existing virtual technology, that is, a virtual device can be created by installing a virtualization host or an agent task executor on a computer. The generation of the virtual device can be completed through step S1. The hardware device and the virtual device constitute the basic device resource at the bottom of the resource. In step S2, unified management of physical devices and virtual devices can be realized by combining IaaS technology. Step S3 may adopt the web service method of the prior art, and realize the creation of the service interface through the Service-Oriented Architecture (Service-Oriented Architecture, SOA for short) technology. Step S6 can combine the existing App Store mode to build an upper-layer service interaction platform for presenting various application services.

Further, in order to maintain the running security of the hardware device and the virtual device, in the above implementation process, the management strategy includes: a storage and maintenance management strategy for the mapping relationship between the virtual device and the hardware device; or the management strategy further includes: Resource operation and maintenance management strategy and security monitoring management strategy.

Furthermore, in the above implementation process, the creation of application services described above builds a management middle layer based on the created application services, as shown in Figure 8, and the specific implementation is as follows:

Step S501, creating a middleware instance and generating a middleware resource pool;

Step S502, creating a database instance and generating a database resource pool;

Step S503, creating a WEB service instance and generating a WEB service resource pool;

Step S504, based on the generated resource pools, create deployment, management and maintenance strategies for each instance in each resource pool;

The construction of the management middle layer can be based on PaaS technology, which integrates various existing business capabilities, which can be specifically classified into application servers, business capability access, business engines, and business open platforms. Service capability, calling hardware resources through the API provided by IaaS, and providing an open interface to SaaS users through the API. The most fundamental difference between the services provided by PaaS and other services is that what PaaS provides is a basic platform, not some kind of application. The essence of PaaS is to turn resource services into programmable interfaces and provide resources and service platforms for upper-level business development.

What needs to be explained here is: the SOA technology mentioned above is a component model, which connects different functional units (or services) of the application program through well-defined interfaces and contracts between these services. The definition of the interface is independent of the hardware platform, operating system and programming language that implements the service. Services built into such systems can interact in a unified and general manner. Defining characteristics through interfaces is called loose coupling between services. The benefits of a loosely coupled system are both its flexibility and its ability to survive when the internal structure and implementation of each service that makes up the entire application changes gradually.

The open architecture of telecom IT resource support system based on SOA and PaaS technology is an important technology that conforms to centralized management and IT concentration at present, and it is also the development trend of telecom IT architecture in the future.
