Method for implementing intelligent network emergency back call service and system thereof

Abstract

The invention provides an implement method and a system of intelligent network emergency callback service, wherein, the method includes the following steps: step A: a calling party sends unstructured supplementary services data (USSD) containing the information of called party number, calling frequency and times of calls to a USSD center; step B: the USSD center sends the USSD information to a callback center; step C: the callback center activates callback service according to the USSD information and judges whether the calling of this time is successful or whether the number of calls reaches the number of calls in the USSD information; if so, the calling request is deleted; or, the calling request is re-initiated. According to the invention, callback with a certain frequency and times of calls can be implemented when emergency services are needed.

Description

technical field [0001] The invention relates to an intelligent network system, in particular to a method and system for realizing an emergency callback service of an intelligent network. Background technique [0002] The intelligent network is a very mature implementation solution of value-added services in the telecommunication system. It can provide users with flexible and changeable service attributes, such as voice calls, short messages, and interactive voice response (Interactive Voice Response, IVR) processes and so on. At present, the mobile phone has become the instant communication tool that people rely on most. But in some cases, the called user may temporarily shut down the phone, and at this time, if there is an urgent matter and needs to be contacted with the called party, the calling party will have to call the called number again and again. [0003] An existing intelligent network system includes an Unstructured Supplementary Service Data (Unstructured Supple...

AI Technical Summary

Problems solved by technology

The existing call-back service is generally the USSD center. After receiving the call-back request, only one call is made to the calling party and the called party. There is no control on the frequency and number of calls, and the application scenarios are mostly international roaming to non-mobile network enhanced logic. The callback function is only used in the customized applications (Customized Applications for Mobile network Enhanced Logic, CAMEL) network, or when the calling party wants to save the cost of international roaming calls, which greatly limits the application scenarios of the callback function
