Communication network, communication network node, user equipment, and method for providing mobility as a service
The present disclosure generally pertains to a communication network for providing a distributed ledger having a plurality of network nodes comprising circuitry configured to: provide a passenger profile of a passenger to a roaming mobility service provider in response to a booking request, wherein the passenger profile is provided from a home mobility service provider; and provide passenger information based on the passenger profile to a transport operator for allowing a passenger to use a mobility service of the roaming mobility service provider.
1 . A system, comprising:
a user equipment;
an identity hub;
a transport operator; and
at least one processor coupled to a memory that stores machine readable instructions thereon which, when executed by the at least one processor, causes the at least one processor to perform the steps of
transmit, from the user equipment to a roaming mobility service provider, a booking request for a mobility service,
receive, at the user equipment from a transport operator via the roaming mobility service provider, a request for advanced passenger information,
receive, at the user equipment, user consent to share the requested passenger information,
transmit, from the user equipment to the identity hub based on the received user consent, a request for at least one DID-based credential of a plurality of credentials, wherein the at least one DID-based credential is stored in a decentralized database, and wherein the at least one DID-based credential is issued by a third party authority, wherein the request includes a booking request and necessary passenger information,
receive, at the user equipment from the identity hub, a subset of information selected by the identity hub from the at least one DID-based credential, wherein the subset of information satisfies requirements of the transport operator while minimizing disclosure of personal information of the passenger, and wherein the identity hub selects the relevant credentials based on the booking request and necessary passenger information,
transmit the subset of information to the transport operator for allowing the passenger to use the mobility service of the transport operator based on an enquiry of the decentralized database without revealing unnecessary personal data of the passenger,
wherein the transport operator verifies the subset of information without accessing a home mobility service provider, and
receive a confirmation of authorization of the passenger to use the mobility service based on the transmitted subset of information.
2 . The system of claim 1 , wherein the at least one DID-based credential is verified from the transport operator for allowing the passenger to use a mobility service of the transport operator.
3 . The system of claim 2 , wherein the at least one DID-based credential is verified based on an enquiry of a centralized database.
4 . The system of claim 3 , wherein the at least one processor is further configured to assign the centralized database to at least one issuer of the at least one DID-based credential.
5 . The system of claim 1 , wherein the decentralized database is based on a blockchain.
6 . The system of claim 1 , wherein the at least one DID-based credential is verified based on a hash function.
7 . The system of claim 6 , wherein the at least one DID-based credential is further verified based on a Merkle tree.
