A method for an access network of a telecommunications network includes: in a first step, a first authentication, authorization and accounting (AAA)-related message is sent by an authentication server entity and received by an access orchestrator entity, the first AAA-related message comprising: at least one standardized message attribute according to an access protocol; and at least one vendor-specific message attribute; in a second step, subsequent to the first step, the access orchestrator entity sends a second AAA-related message to a service edge entity, the second AAA-related message solely comprising the at least one standardized message attribute according to the access protocol; and in a third step, subsequent to the first step and prior to, during or after the second step, the access orchestrator entity sends at least one third AAA-related message to the service edge entity, the at least one third AAA-related message corresponding to a message according to an application programming interface (API) or to a further access protocol.

A data volume exchange server includes a terminal IF unit configured to receive an exchange request for a contract data volume of an own country and a contract data volume of another country from terminals of subscribers having contract data volumes of telecommunication carriers of countries different from each other, a data volume exchange unit configured to perform matching of a pair in which another country that requests a contract data volume in one of the received exchange requests matches the own country that provides a contract data volume in another of the received exchange requests, and a server IF unit configured to instruct the communication servers of the telecommunication carriers in the countries to transfer a contract data volume of a matched subscriber of the own country as an exchanged data volume of a subscriber of the other country who is a matching partner.

In some embodiments, the present disclosure is directed to an exemplary system, including: an access controlling platform, executing software instructions that instruct to generate an expectation data record as an access control mechanism to access an access-restricted digital resource, the expectation data record including: access code and identity linked to a computing device; where the access code is associated with the access-restricted digital resource; receive a mobile originating communication having data that includes a particular access code and a particular identity; perform a confirmation of the expectation data record with the mobile originating communication; instruct a cellular communications network to perform, based on at least one part of the data, at least one action with the cellular network hosted access controlling schema to generate a session record associated with the particular identity; and instruct to unlock the access-restricted digital resource for the accessing via the computing device.

A processing system may maintain a communication graph that includes nodes representing a plurality of phone numbers including a first phone number and edges between the nodes representing a plurality of communications between the plurality of phone numbers and may generate at least one vector via a graph embedding process applied to the communication graph, the at least one vector representing features of at least a portion of the communication graph. The processing system may then apply the at least one vector to a prediction model that is implemented by the processing system and that is configured to predict whether the first phone number is associated with a type of network activity associated with a telecommunication network and may implement a remedial action in response to an output of the prediction model indicating that the first phone number is associated with the type of network activity.

A processing system may maintain a relationship graph that includes nodes and edges representing phone numbers and device identifiers having associations with the phone numbers. The processing system may obtain an identification of a first phone number or a first device identifier for a fraud evaluation and extract features from the relationship graph associated with at least one of the first phone number or the first device identifier. The plurality of features may include one or more device identifiers associated with the first phone number, or one or more phone numbers associated with the first device identifier. The processing system may then apply the features to a prediction model that is implemented by the processing system and that is configured to output a fraud risk value of the first phone number or the first device identifier and implement at least one remedial action in response to the fraud risk value.

One disclosed system includes dialer device with a dialer identifier that initiates a call with a receiver device with a receiver identifier over a voice channel. A database stores: interaction data in association with both the receiver identifier and the dialer identifier; a content quality metric in association with the interaction data; and a network topology in which the receiver identifier and the dialer identifier are associated with nodes and are connected by an edge. A server is programmed to: update, based on the content quality metric and the network topology, a rankings associated with the receiver identifier and the dialer identifier; and one of: surface the ranking associated with the dialer identifier and the ranking associated with the receiver identifier to an external searching agent using an external data channel and without using any voice channel; or rank the dialer identifier for an internal searching agent using the ranking.
