Abstract: Various communication systems may benefit from appropriate handling of secure data. More specifically, certain packet-based communication systems may benefit from a mechanism to support coordinated packet delivery of one or more encrypted sessions. A method can include identifying metadata for an application flow, wherein the application flow is encrypted. The method can also include publishing the metadata in a core network, wherein the metadata is unencrypted when published.

Abstract: Various techniques are provided for generating, by a base station (BS), a user equipment (UE) report for a UE associated with the BS, associating, by the BS, an application identification or correlation (ID) along with the UE report, the ID being associated with an application category being served by at least one data radio bearer (DRB) or it is an identifier referring to a specific application detection filter identifying an application that is served by the DRB, receiving, by the BS, assistance information based on the reports sent for the DRB, the assistance information being associated with the application, and scheduling, by the BS, resources for the UE based on the assistance information.

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.

Abstract: A method comprises determining if a failure has occurred in a first path, an offload application server functionality being provided in said first path and if so, causing routing of said data via a second different path which bypasses said offload server functionality.

Abstract: Providing secure radio information transfer over a mobile radio bearer by generating one or more secret keys, applying symmetric encryption to unencrypted radio information to generate encrypted radio information, applying a keyed hash operation to the unencrypted radio information using the generated one or more secret keys to generate a message digest, and transmitting both the encrypted radio information and the message digest over a network.
