Method for implementing unstructured user data function in CDMA intelligent network business

Abstract

The present invention discloses a method for realizing a USSD function by a CDMA intelligent network business based on an OCS, which comprises the following procedure: a CDMA user sends a call request to the CDMA intelligent network, sends a relevant access code, and activates the intelligent business of the control point of the user attributing business through the subscription information; the CDMA user sends the call request to the CDMA Intelligent Network, sends a relevant access code, and activates the intelligent business of a control point of the user attributing business through the subscription information; the unstructured user data centre deals with the intelligent business through user online charging system and sends the relevant settlement results through the short message. Compared with the prior art, the method realizes a user account management function and an international roaming recall function in the CDMA network by the way of the OCS.

Description

technical field [0001] The invention relates to the technical field of CDMA intelligent network, in particular to a method for realizing unstructured user data function by CDMA intelligent network service. Background technique [0002] In the current CDMA intelligent network, we have achieved billing control and the separation of billing and call signaling. Our intelligent network services can be implemented through the Diameter protocol (Diameter credit control, DCC) , MML) interface messages interact with the Online Charging System (Online Charge System, OCS) to implement the entire process of signaling control and account operations involved in a call. [0003] In the current CDMA intelligent network, it is not possible to directly realize functions such as instant display of messages through calls and call back to intelligent users in the GSM intelligent network through the USSD (Unstructured Supplementary Service Data, Unstructured Supplementary Service Data) technology...

AI Technical Summary

Problems solved by technology

[0004] In the CDMA intelligent network, the wireless intelligent network (WIN) protocol is adopted, and the WIN protocol does not support the international roaming of intelligent users, so the CDMA intelligent network cannot Realize the interaction between the terminal user and the home HLR through the message, and at the same time, the relevant USSD center service cannot be triggered through the HLR to provide functions such as user account query, management, and authentication callback.
