Abstract: Various communication systems may benefit from ways of communicating in the absence of a centralized authority. For example, certain wireless communication systems may benefit from victim to victim communication using over-the-top (OTT) identities in a disaster device-to- device (D2D) scenario. A method can include authenticating with an authentication server of an over-the-top service. The method can also include storing an identity certificate upon receiving the identity certificate from an identity server of the over-the-top service. The identity certificate can be configured to provide credentials of the over-the-top service when a centralized authentication authority of the over-the-top service is unavailable.

Abstract: Systems, methods, apparatuses, and computer program products for cooperative application and network insight operations in wireless networks are provided. One method includes, during application content delivery to a user equipment (UE) associated with a network, monitoring and/or collecting instantaneous radio information from a network node and computing at least cell load and throughput for the network. The method may then include sending the collected radio information, cell load, and throughput information to an application server that is delivering content to the user equipment (UE).

Abstract: Information is determined affecting data presentation of part of a data stream to a user application on a UE, and may be EC information and/or QoE information caused at least by the data presentation. The information is sent from the UE toward a content server from which the data stream is received by the UE. At radio network element(s), radio timer information corresponding to data transmission of part of the data stream from a base station to a UE is determined and sent (e.g., possibly with the energy consumption information and/or QoE information) to other radio network elements and/or to the content server. The content server can adjust streaming strategy of the data stream based on the information received, and the radio network element(s) can perform power aware scheduling and/or radio timer adjustments based on received EC information and/or the QoE information.
