Billing method and system for code division multiple access international roaming short message

Abstract

Embodiments of the invention disclose a method and a system for charging of code division multiple access international roaming short messages. The method comprises: a signaling transfer point receiving a first MO message sent by a roaming place MSC, reading an MSCID parameter value from the message, writing the value in a second MO message, and transferring the second MO message to a MC belonged to a short message initiator; the MC belonged to the short message initiator reading the MSCID parameter value and storing same, identifying user attribute of the short message initiator; if the user is a pre-paid user, sending an authentication message to an OSC platform, the authentication message comprising the MSCID parameter value; the OCS charging for roaming short messages according to the MSCID parameter value, if the short message is not successful in sending, supplementing money; if the user is a post-paid user, after the user receives a short message state report, filling the MSCID parameter value in a short message ticket, and sending the ticket to a charging center; and the charging center charging for the roaming short messages according to the MSCID parameter value. The method and the system can charge for international roaming short messages from pre-paid users and post-paid users, and can charge for international roaming aiming at short messages which are sent successfully.

Description

technical field [0001] The invention relates to communication technology, in particular to a charging method and system for code division multiple access international roaming short messages. Background technique [0002] Code Division Multiple Access (CDMA) network users realize international roaming, that is: CDMA network users leave the network of their home country to roam in the network of overseas operators and enjoy CDMA services. At present, CDMA international roaming signaling intercommunication generally adopts the method of transit and protocol conversion through a third-party independent telecommunications service roaming service provider to realize CDMA network intercommunication among multiple countries. [0003] CDMA international roaming SMS refers to CDMA users receiving and sending short messages (also called short messages) within the network of overseas operators. The common implementation method is to transmit the Short Message Deliver Point-to-Point (S...

AI Technical Summary

Problems solved by technology

[0006] The deployment of the signaling monitoring system requires huge investment and cumbersome deployment;

[0007] After the short message is sent successfully, the short message status report will be replied to the short message center of the short message sender, and the signaling monitoring system will not be notified, so the signaling monitoring system cannot know whether the short message is sent successfully, so the international roaming generated by the signaling monitoring system The SMS call list is not accurate, and there may be cases where the unsuccessful SMS is also charged to the user;

[0008] Since the signaling monitoring system is generally not connected to the Online Charging System (OCS) platform, this method cannot deduct international roaming SMS charges from prepaid users in real time, resulting in the risk of arrears
