Method for controlling business interchange point number receiving

Abstract

The invention relates to a method for controlling number collection by a service switching point. Firstly, the service switching point reports the number received from the local switching equipment to the service control point, and then the service control point judges whether the number is complete. If the number is incomplete, then The service control point controls the service switching point to obtain the remaining numbers from the signaling message sent by the local switching device according to the INAP protocol, and then the service switching point reports the obtained remaining numbers to the service control point. By implementing the present invention, when the number reported by the service switching point is incomplete, there is no need to switch from receiving the number through signaling to receiving the number on the voice channel, thereby effectively avoiding number loss and ensuring call reliability. At the same time, the present invention is convenient to implement and simple in data configuration , Strong networking ability.

Description

technical field [0001] The invention relates to an intelligent network, and more specifically, relates to a method for controlling number collection of a service switching point. Background technique [0002] In the virtual private network (Virtual Private Network, VPN for short) service of the intelligent network mode, the Service Switch Point (Service Switch Point, SSP for short) reports the called short number dialed by the calling user to the Service Control Point (Service Control Point, Abbreviated as SCP), the service control point analyzes the short number / long number correspondence table to find the corresponding long number, sends the long number through the connection message (Connect), and instructs the service switching point to continue the called according to the long number. [0003] During this process, the VPN service requires that the SSP can report the complete called short number to the SCP at one time in the Initiate Detection Point (IDP) message, or the...

AI Technical Summary

Problems solved by technology

This method of number collection avoids the problem of complex data configuration in the first method, but because this method is implemented through the session channel, after receiving the CTR and PC, the SSP needs to allocate number collection resources and network, and at the same time through inter-office signaling Instruct the LE to connect to the network, and the LE initiates a call to the SSP by transmitting the called short number through the signaling message on the link. It is easy to lose the number and cause the call to fail
