Description

TECHNICAL FIELD

The present invention relates to a system which enables to generate call detail records related to voice and sms voice communications of the said persons upon foreigners-who are roaming—communicate with each other over voice and sms by using VOLTE, and ensures that the data traffic occurring in the network as a result of voice, sms, video-based agreements made with foreigners can be observed by the network.

BACKGROUND OF THE INVENTION

Today, mobile communication is carried out by the standards set by the 3GPP organization. Users can communicate with each other by means of their mobile devices supporting VOLTE feature that realize voice transfer over LTE, with high sound quality. Communication networks charge persons, who communicate over VOLTE, only on a mobile data basis. However, communication networks make agreement with their own subscribers or foreign subscribers—who are roaming—such as minute-based voice, minute-based video and number-based sms. In the current technique, users—who are roaming—are charged only on a mobile data basis when they are charged. In the state of the art, there is no solution which enables to generate call detail records related to voice, video, sms communications realized by persons-who perform VOLTE roaming—between the network wherein they roam and their own local network; to decode communication protocols such as session initiation protocol (SIP), user datagram protocol (UDP), transmission control protocol (TCP) and internet protocol (IP) by means of a function that serves during generation of call detail records of the persons who performs VOLTE roaming; to eliminate the loss of income based on erroneous estimation in agreements between the foreign network and the local network by providing visibility to commercial teams upon call detail records of the persons-who perform VOLTE roaming—are generated from voice, video, sms data.

Due to the abovementioned reasons, there is need for a system for generating voice, video and short message call records from data in VOLTE roaming which enables to generate call detail records related to voice, video, sms communications realized by persons-who perform VOLTE roaming—between the network wherein they roam and their own local network; to decode communication protocols such as session initiation protocol (SIP), user datagram protocol (UDP), transmission control protocol (TCP) and internet protocol (IP) by means of a function that serves during generation of call detail records of the persons who performs VOLTE roaming; to eliminate the loss of income based on erroneous estimation in agreements between the foreign network and the local network by providing visibility to commercial teams upon call detail records of the persons-who perform VOLTE roaming—are generated from voice, video, sms data.

The United States patent document no. US2021227001, an application in the state of the art, discloses a system and method for implementing a VOLTE and circuit switched voice and SMS interworking function to provide voice and SMS service to roaming mobile devices at visiting network based on VOLTE roaming and ‘SMS over SGs’ towards VPLMN, and circuit-switched voice and SMS towards HPLMN. The interworking function enables and redirects IMS traffic at VPLMN towards a hosted IMS core with voice connectivity to PSTN via MGCF and MGW. The interworking function also performs circuit-switched location-update registration at HLR at HPLMN for receiving mobile-terminated voice calls and SMS.

SUMMARY OF THE INVENTION

The objective of the present invention is to realize a system for generating voice, video and short message call records from data in VOLTE roaming which enables to generate call detail records related to voice, video, sms communications realized by persons-who perform VOLTE roaming—between the network wherein they roam and their own local network; to decode communication protocols such as session initiation protocol (SIP), user datagram protocol (UDP), transmission control protocol (TCP) and internet protocol (IP) by means of a function that serves during generation of call detail records of the persons who performs VOLTE roaming; to eliminate the loss of income based on erroneous estimation in agreements between the foreign network and the local network by providing visibility to commercial teams upon call detail records of the persons—who perform VOLTE roaming—are generated from voice, video, sms data.
