Description

A bill processing method, system and storage medium for roaming service

technical field

The present invention relates to the field of communication technologies, and in particular, to a bill processing method, system and storage medium for roaming services.

Background technique

The international roaming service is carried out between operator A and operator B. When a user of operator A roams to the service area operated by operator B, the service provided by operator B is used. The user pays a fee to operator A, and operator A Pay operator B for roaming service. At this time, operator A is the home operator, and operator B is the roaming operator, and their identities are interchangeable. In the existing actual process, the voice, short message, data traffic and other traffic generated by international roaming (visiting and visiting) are involved. Single verification; and according to the signed contract (traffic volume, business volume, unit price and discount) to generate accounts receivable bills and write-off reports, and reconcile with relevant international operators.

However, the prior art may suffer from one or more of the following problems:

(1) The CDR formats for roaming services generated by different counterparty operators all meet the GSMA standards, but the bill formats may be different and are not fully standardized (only a few large settlement centers have standardized formats, and more than 500 operators around the world have The billing format has not been standardized); its billing method and account reconciliation method cannot be unified, and it needs to be manually adapted one by one, which is inefficient.

(2) Signed billing contracts with different operators as the billing basis. If the contracts used by both parties are inconsistent or tampered with, it will increase the cost of disputes and corresponding declaration processing.

(3) Both parties need to reconcile their roaming service CDRs and bills, and each needs to maintain its own account book. If the roaming service CDR and account book are inconsistent due to errors or tampering in the process of transmission or storage, disputes and corresponding declarations will be increased. cost.

(4) The home operator does not review the authenticity of the content of the roaming service CDR. If there is a problem with the CDR content or the end user disagrees with it, such as time precision difference, duration, CDR status (connected, not connected) ) are inconsistent, and the user may find out and file an application only after receiving the detailed bill of charges sent by the home operator. If the problem is not an independent event but a failure of the home operator's billing system, it may affect more users due to untimely discovery, communication, and resolution.
