A centralised identity and capability resolution server (ICRS) keeps track of which user or subscriber is logged in on every device in a communications ecosystem and maintains the state of user, device and service relationships based on multiple external events. Each subscriber is provided with a unique identifier within the ecosystem or unique ecosystem identifier. The ICRS establishes an association between the service identifier, user and particular device that a user is using for that service. The devices within the ecosystem are configured to inform the ICRS of new accounts, or changes affecting existing accounts, such as cancelling of an account or loss of device. In that way, the ICRS has up to date state of the relationships between user or subscriber identifiers, devices, and various service identifiers. This enables ICRS to retrieve any identifier associated to the subscriber when any other identifier belonging to the user is provided. |
