Problems solved by technology

[0015] When using the VPN service, as can be seen from the call flow of the above-mentioned WIN user as the calling user, the existing WIN protocol only supports changing the called number (for example, converting the called short number in the VPN network to the called number) Calling the user's real number), does not support the transformation of the calling number, and cannot meet the user's needs for displaying the calling number

Embodiment Construction

[0038]The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation of the present invention.

[0039] In the mobile application part (Mobile Application Part, MAP) protocol used by the wireless intelligent network service, the calling number information is represented by the parameter CallingPartyNumberDigits1 and the parameter CallingPartyNumberString1. When MSC / VLR sends ORREQ message / ANLYZD message to SCP, use CallingPartyNumberDigits1 parameter to carry calling number; when SCP sends orreq message to MSC / VLR, use CallingPartyNumberString1 parameter to carry calling number. The structure of an orreq message is as follows:

Abstract

The invention discloses a calling number transformation method, a system and a service control point. The method comprises the following steps of: after the service control point receives a call from a service switch point, judging whether a calling subscriber of the call signs calling number transformation service or not; and if so, searching a new number corresponding to the calling number of the call in the service control point, sending the new number to the service switch point, and using the new number in the following calling procedure by the service switch point. Through the calling number transformation method, the system and the service control point, provided by the invention, the current WIN (Wireless Intelligent Network) protocol is expanded; and the SCP (Service Control Point) judges whether to transform the calling number or not, if so, the new number is fed back to the SSP (Service Switch Point) through an orreq and/or anlyzd message, so that the calling number is transformed.

Description

technical field [0001] The invention relates to the field of CDMA wireless intelligent network, and more specifically, relates to a calling number changing method, system and service control point. Background technique [0002] The wireless intelligent network (Wireless Intelligent Network, WIN) service is triggered based on the subscription information. When a WIN user opens an account, he first signs up to the service control point (Service Control Point, SCP) on the home location register (HLR, Home Location Register) , and select a trigger related to the business. When the service switching point (Service Switch Point, SSP) receives a call of an intelligent network service, it will send the information related to the call to the SCP through the WIN message, and wait for the instruction of the SCP. The SCP will, according to the trigger information signed by the user, Execute the corresponding business logic, and send the corresponding operation command to the SSP, or th...
