Problems solved by technology
[0007] 1. The current trunk resource control system for the virtual switchboard service can only realize single-point control, that is, it can only implement trunk resource control for calls of group users in the same geographical area, and cannot realize multi-point control, that is, it cannot Realize multi-point coordinated management and control of relay resources in multiple geographical areas, and it is impossible to realize large-scale virtual switchboard services
[0008] 2. The relay resource control system based on the existing network architecture cannot provide a mature and effective backup and redundancy mechanism, which also makes it difficult to guarantee the reliability of the existing relay resource control system applied to the virtual switchboard service. If a certain device fails, it is difficult for the existing system to perform rapid fault recovery and redundant switchover, and the average fault duration is long, which directly affects the normal operation of the virtual switchboard business

Embodiment Construction
[0042] Various preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0043] According to the method of the present invention applied to the control of virtual switchboard service relay resources, as shown in Figure 1, multiple group user extensions can access the virtual switchboard service from one or more geographical areas, and these multiple geographical areas are responsible for their own Group users in the region realize access, and are also responsible for collaborative management and control with service control point SCPs in other regions, thereby realizing large-scale virtual switchboard services across multiple geographical regions.
[0044]As shown in Fig. 2a ~ Fig. 2c is the functional block diagram of the service control point SCP with the relay resource management function of the present invention, which includes the relay resource control information routing table, the relay resource usage...

This invention relates to a method for controlling relay resources used in the virtual phone exchange services including that the relay resource uses a login process and a logout process based on No.7 signaling, in which, the login process includes: a group user initiates a virtual phone exchange service call, a service exchange point of the region where the group user places transmits the related information of said user and the relay register request of the resource to the service control point by No.7 signaling to decide it and organize register response information to be sent to relative service exchange points by No.7 signaling based on the configuration data and current applied situation, which decides operation of the next step based on the response information fed back by the service control point to decide if this time of call is permited, which realizes unified management and control of relay resources and saves large amount of networks and terminal devices.
Description
technical field [0001] The invention relates to the application technology of the virtual switchboard service, more specifically, relates to a method for controlling the relay resource of the virtual switchboard service based on the No. 7 signaling network. Background technique [0002] Virtual switchboard service is a technology that uses virtual switchboard equipment to provide virtual switchboard number services for the group. This technology is that the switching network operator provides virtual switchboard number services for the group through virtual switchboard equipment and manual centralized services. The virtual switchboard number can be fixed-line phone number, mobile phone number, etc., and the manual centralized service can provide manual services such as number checking and secretarial services for all virtual switchboards of the group. Groups that have applied for a virtual switchboard can assign extension numbers to their employees through the management int...
