Section: 6.45.1 Overview
Content: In the roaming ecosystem, a roaming services provider provides the technical and commercial means to facilitate the deployment and operation of roaming services between a client operator and a set of selected connected operators. The roaming services provider handles the technical implementation of the roaming relations in a scalable and operationally efficient way. With a roaming services provider present in the roaming ecosystem, operators can choose not to establish a bilateral direct agreement with specific operators. A trusted relation exists between the involved operator and the roaming services provider. Roaming services providers, according to their role and responsibilities, assume financial and technical liability to apply all necessary controls and access to all communications. Among other functionalities, a roaming services provider needs to: • Process identifiers and potentially other information transmitted in signalling messages between PLMNs in a secure manner. • Be able to modify, add or delete information that is relevant to their role, respecting what is contractually agreed in service level agreements (SLAs) and enforced technically. • Isolate the individual operator signalling flows from each other • Report on the detection of and mitigation of security breaches.
