Abstract: A protocol converter includes a processor configured to receive a request for content from a client system. The processor is further configured to determine if the protocol converter is currently receiving the content through the multicast session, and join the multicast session if the protocol converter is not currently receiving the content. Additionally, the processor is configured to receive the content as an end point of the multicast session, format the content for communication to the client system, and provide content to the client system in a communication separate from the multicast session. Receiving the content as an end point of the multicast session can include terminating the application layer protocol used by the multicast session. Additionally, formatting the content can include re-encapsulating the content as hypertext transport protocol (HTTP) with an appropriate content-type.

Abstract: The embodiments herein relate to a method in a UE (101) for handling ESM information. The UE (101) supports reception of information to be used in determination of the ESM information. The UE (101) receives, from an MME (105), information about at least one supported EPS network feature which the UE (101) may use. The information is received before the UE (101) sends ESM information to the MME (105). Based on the received information, the UE (101) determines the ESM information for a PDN connection for the UE (101). The UE (101) sends the determined ESM information to the MME (105).

Abstract: Methods, apparatuses, and devices are described for wireless communications in which neighborhood area network (NaN) information may be requested and provided in a relatively fast and efficient manner between devices of a NaN. A wireless communication device, such as a station in a wireless communications network, may transmit an active probe request to seek information related to a NaN.

An AP or master device of the NaN may receive the probe request and generate a NaN discovery response, which may include information that the requesting device may use for connecting to a device in the NaN.
