Data Roaming Transport_
Data Roaming Transport is the service that brings together data transmission needs in 2G/3G roaming and in 4G (LTE) roaming.
GPRS is a mobile data service oriented to packets and is offered over 2G and 3G networks. The GPRS service was initially standardized by ETSI (European Telecommunications Standards Institute) and is now maintained by 3GPP (3rd Generation Partnership Project).
LTE, or 4G technology, represents the evolution and future of mobile communications. The system has the required capacities to enable data roaming with the S8 interface. Currently this technology is being developed by 3GPP.
This service is offered as part of our IPX Suite. Like any other voice or data service over IPX, (ASP Access, Sigtran, etc) it is an interconnection solution for which the requirements are defined by the GSMA Association and more specifically, in IR.34. Requirements for IPX Services have also been discussed and analysed by other working groups as well as in i3Forum.
IPX is an evolution of the GRX (GPRS Roaming eXchange) service defined by the GSMA in order to interconnect mobile operators to provide GPRS Roaming. It is a model that integrates different IP services with any kind of Service Providers in one common platform with the assurance of E2E Quality of Service.
Our IPX solution follows the different QoS standards set by the GSMA, E2E SLAs, network development as well as access and CPE management.
IPX Architecture builds on what we already know about GRX Service. It adds ENUM functionality to DNS to allow the translation of phone numbers and also adds IPX Proxy elements to allow cascade billing and the interconnection of different services.
Data Roaming Transport provides IP access to mobile end-users. Users can access both public and private networks, download e-mails, visit an intranet and gain ftps access, providing the mobility that they enjoy with his/her mobile phone at home and abroad.
