Method for providing virtual telephone exchange service by intelligent network

Abstract

Using intelligent network, the method provides service of virtual switchboard. Through data center of group users, virtual group users obtain an authorized virtual group number after opening an account. User obtains authorized virtual switchboard number and extension number. When user uses dialing mode of inner user, i.e. short number of extension, service exchange point is based on number to be analyzed: For a call to called number as extension number of group, sending request command of triggering service to service control point to trigger service of virtual switchboard in intelligent network. The method provides short number of extension easy to be remembered. Realizing dialing short number each other inside virtual group, the method expects to simulate and reach all functions of realswitchboard in enterprise fully. Virtual switchboard does not carry out authentication so as to let users dial to virtual switchboard conveniently.

Description

Technical field [0001] The invention relates to the field of data communication, in particular to a method for providing virtual switchboard services for group business users by using a communication intelligent network. Background technique [0002] In the current data communication field, in order to realize the enterprise's own switchboard service, the more advanced technology is the method of using virtual switchboard equipment to provide the group with virtual switchboard number service invented by Hou Wanchun. The patent application number is 200410024279.3. Some enterprises realize their own The switchboard service is the method used. This method uses the virtual switchboard device, and the method of connecting to the virtual switchboard device through the communication switch realizes the enterprise's own switchboard service, such as figure 2 As shown; earlier methods of using PBX to implement switchboard services, such as figure 1 As shown, there have been great improvem...

AI Technical Summary

Problems solved by technology

[0005] Although this way of implementing switchboard service is much lower than the previous way of realizing switchboard service through the enterprise's own PBX, there are still restrictions on use and waste of cost investment.

[0006] First of all, when the user dials the switchboard number of the company, the calling number needs to be authenticated, so that users who are not allowed by the company cannot successfully dial the switchboard of the company, especially for potential customers of the company, which will cause great negative effects influences

[0007] Secondly, assign a corresponding temporary number to each virtual switchboard number in the virtual switchboard device, and control the calling user switch to temporarily establish a call to the virtual switchboard device, and retrieve the group according to the virtual switchboard number corresponding to the temporary number. When a user sends a call to the virtual switchboard number, it will inevitably lead to repeated access to the virtual switchboard device twice, and there is an operation of assigning a temporary number. As a result, when the number of calls from users connected to the virtual switchboard device is large, the resource consumption Huge waste, especially for the province-wide construction plan, resource consumption will be very large

[0008] Again, the most significant shortcoming of this method of realizing switchboard service is that the realized switchboard service cannot completely replace all the functions of the switchboard service realized by using PBX. For companies with scattered departments and most small and medium-sized enterprises, this After building its own switchboard, the function of dialing through the switchboard cannot be reflected in the internal communication of the enterprise. When members of the enterprise directly dial each other, the call path will not pass through the virtual switchboard device. In this case, the user cannot Realizing the convenience and cost savings of the enterprise switchboard, the internal communication cost of the enterprise is still high and has not improved.
