Therefore, when the short message reaches the home network through the ISTP (International Signaling Transfer Point), the protocol conversion gateway and the SMS center of the home network cannot know the roaming location of the calling party, and cannot transmit the roaming location information of the calling party to the online billing center. The billing center is also unable to perform real-time deduction and credit control for users according to the roaming rate.
[0005] Therefore, between heterogeneous networks, such as between CDMA (Code Division Multiple Access) networks and GSM networks, issues such as protocol conversion, roaming information confirmation, and SMS center bill processing are involved, and international roaming between heterogeneous networks has not yet been realized. SMS prepaid service

The invention, which relates to the field of the prepaid international roaming service field, discloses a method and system for realizing a prepaid service of an international roaming short message of a heterogeneous network. According to the invention, a protocol conversion gateway extracts subscriber roaming area information from a network layer of a heterogeneous network roaming short message; the subscriber roaming area information is added to the short message after format conversion; the short message with the subscriber roaming area information is sent to a short message center; the short message center transmits the subscriber roaming area information to an on-line billing center; and the on-line billing center carries out real-time rating deduction on the roaming charges according to the subscriber roaming area information. Therefore, the prepaid service of the international roaming short message of the heterogeneous network is realized.
Description
technical field [0001] The invention relates to a prepaid international roaming service, in particular to a method and a system for realizing a heterogeneous network international roaming short message prepaid service. Background technique [0002] With the development of communication technology, the user group of prepaid service is getting bigger and bigger. The so-called prepayment means that the user must pay the fee in advance before using the service, and this fee will be deducted after the user successfully uses the service. [0003] At present, international roaming SMS prepaid services have been realized among GSM (Global System for Mobile Communications) operators. The roaming information of the user is directly carried in the message between the homogeneous networks, and the online billing system can directly obtain the roaming information of the user for charging. [0004] Different from homogeneous networks, the current short message structure between heteroge...
