Embodiment Construction

[0040] Since the user information of the intelligent network user is stored on the SCP, the present invention mainly solves how to trigger the call initiated by the intelligent user in a different place to the SCP to which the intelligent user belongs. And because general MSC all supports USSD function, adopt USSD signaling to transmit control message and have versatility, based on this, the realization idea of ​​the present invention is exactly: when roaming smart user initiates a call as calling party, this smart user sends a USSD request, the smart user's home SCP controls and establishes the call connection, respectively sets up the call between the service switching point (SSP) to the smart user and the called user, and then all the calls between the SSP to the smart user and the called user After the establishment is successful, the two connected half-calls are finally bridged through the SSP to realize the call between the calling party and the called party.

Abstract

The method includes such steps as (a) when as calling party launches a calling, roaming intelligent user sends operation code of unstructured supplementary service data (USSD) and request of USSD of called user's number to attributive service control point (SCP); (b) after receiving USSD request, SCP determines whether operation code of USSD is a service of UCB returned from USSD and whether the calling user is allowed for using UCB service; if yes, entering into (c); otherwise, ending the flow; (c) attributive SCP of calling user orders relevant SSP to build call jointing from SSP to calling party and SSP to called party respectively, and determines whether building a call is successful; if yes, SSP builds voice channel between calling party and called party, realizing communication; otherwise this flow is ended.

Description

technical field [0001] The invention relates to the roaming call technology of the intelligent user, in particular to a method for the intelligent user to initiate a call under the condition that the intelligent network of the visited place and the home place cannot realize interaction when the intelligent user is roaming. Background technique [0002] At present, in the operation of mobile communication networks such as the Global Mobile Communications (GSM) system and the Code Division Multiple Access (CDMA) system, the number of smart users accounts for an increasing proportion of mobile users year by year. The smart users mentioned here include but not It is limited to users who use prepaid services and users who use mobile virtual private network services. Then, as the proportion of smart users increases, the requirement to provide roaming functions, especially international roaming functions, for smart users becomes more and more prominent. For each smart user, its us...
