Abstract
A scheme for providing access to 6LoWPAN data in a wireless access network. In one embodiment, a Digital Unit (DU) of the wireless access network is provided with IP bridging functionality for packaging 6LO data as a control channel message. When the DU element receives 6LO data from an external router, the data is packaged in a format specified for a control channel associated with a CPRI link coupling to a Radio Unit (RU). The bridging functionality is operative to transmit the control channel message (including the packaged 6LO data packets) to the RU element based on an address mapping between the destination IP address of the 6LO data packets and an address of the 6LO endpoint coupled to the RU element.
