Portal.
- the enterprise switchboard system mainly includes four types of services: enterprise switchboard, integrated VPN, conference call, and information service.
- the integrated VPN refers to the internal short-number dialing and flexible billing as the core functions, aiming to fix the fixed network of the telecom operators in different areas, such as the Public Switched Telephone Network (PSTN), softswitch. , as well as Code Division Multiple Access (CDMA), Global System for Mobile (GSM, Global System for Mobile) Communication ) Users, Next Generation Network (NGN) users form a logical private network. Users in the network can use short numbers or real numbers to contact. Members in the private network can enjoy flexible tariff policies when calling within the network and outside the network.

- NTN Next Generation Network
- a conference call is a service for making multi-party calls by telephone. Participants can use the active or incoming call to access the conference system and make a conference call in a different place within a predetermined time.
- Information services are designed to provide enterprises with a unified information platform. Through manual services or enterprise portals, internal or external customers can obtain real-time online information.
- the current enterprise switchboard system is implemented in two ways, namely: intelligent network mode and intelligent platform mode.
- the virtual switchboard technology is used to implement the virtual switchboard service, that is, the enterprise switchboard service, which mainly uses the design idea of separate call and service control in the intelligent network technology, and separates the terminal call connection from the virtual switchboard service control.
- the service trigger mode the method of triggering the virtual switchboard service to the SCP (Service Control Point) query mode is used.
- FIG. 1 is a schematic diagram of a structure of a virtual switchboard system implemented by using an intelligent network technology in the related art.
- a Service Switching Point SSP
- SCP Service Switching Point
- the SCP is a service control point and is mainly responsible for controlling the virtual switchboard business logic. It is the core part of the virtual switchboard service processing.
- the SCP is connected to the SSP and IP through the No. 7 signaling network or the Intelligent Peripheral (IP) core network.
- IP Intelligent Peripheral
- the communication rules between the SCP and the SSP and IP can use various control signaling, for example: the intelligent network application part/the mobile network enhanced logic customized application (CAMEL) part/mobile application part/session initiation protocol, etc. , IP provides playback, receiving, recording and other functions for the virtual switchboard business.
- CAMEL mobile network enhanced logic customized application
- the advantage of using the intelligent network method is that the voice path is less, especially in the mobile network, each area The MSC (Mobile Switching Center) can serve as the SSP trigger service of the virtual switchboard. There is only a signaling link between the MSC and the switchboard SCP. Since the voice path does not return to the unified switchboard platform, the switchboard system constructed in this way has efficient business processing capabilities and can increase system capacity.

- the intelligent network method also has obvious disadvantages. Since the SSPs are distributed throughout the switching network, and the construction period of the SSP devices in the switching network is different, the processing capabilities of the devices are also different. Therefore, there is no guarantee that the SSP service control commands can be correctly executed by the SSP. For example, the conference call function, the extension simultaneous and forward function, the extension session hold and forward function, and the extension queue function all require the SSP to perform specific call processing under the control of the SCP. However, in the actual network evolution process, with the evolution of control signaling, the SSP cannot support these special call processing, and thus the function development of the switchboard service is greatly limited.
