Aspects relating to data transmission are described herein. In an implementation, in a method for data transmission, a tunneling protocol header is appended to a payload to obtain an encapsulated data packet, and at least one field is modified in the tunneling protocol header to indicate at least one of an access network (108) and a core network (108) for transmitting the encapsulated data packet, and the access network (108) and the core network (110) belong to different communication networks (104). Further, based on the tunneling protocol header, the encapsulated data packet is delivered to a routing unit for transmission.

An apparatus includes a multi-mode optical fiber having a selected plurality of optical propagating modes. The selected plurality may include only a proper subset of or may include all of the optical propagating modes of the multi-mode optical fiber. Each optical propagating mode of the selected plurality has a group velocity that varies over a corresponding range for light in, at least, one of the optical telecommunications C-band, the optical telecommunications L-band, and the optical telecommunications S-band. The ranges corresponding to different ones of the modes of the selected plurality are non-overlapping. The ranges of a group velocity-adjacent pair of the ranges are separated by a nonzero gap of less than about 10,000 meters per second.

Embodiments provide a user equipment (UE) device that includes a processor and a transceiver. The processor is configured to direct a handover request to an evolved packet core (EPC) access node via the transceiver. The access node may be, e.g. a wireless local area network (WLAN) access point or an E-UTRAN access point. The handover request may initiate a transfer of connectivity of the UE device from the WLAN access point to the E-UTRAN access point, or from the E-UTRAN access point to the WLAN access point. The processor is configured to receive a handover response from the current access node, wherein the response includes a cryptographic key identifier, and to derive a handover key from the key identifier. The processor may then operate the UE device to provide connectivity based on the handover key between the UE device and the other of the access nodes.
