1. A method operating at a Digital Unit (DU) element of an access system for providing access with respect to information in Internet Protocol (IP) version 6 (IPv6) over Low Power Wireless Personal Area Network (6LoWPAN) format, the method comprising:

  • receiving 6LoWPAN data (“

    6LO data”

    ) packets from a router coupled to an external packet-switched network;

    examining a destination IP address of the 6LO data packets and determining an address of at least one radio dot (RD) element to which the 6LO data packets are to be delivered;

    determining an address of a Radio Unit (RU) element corresponding to the at least one RD element;

    repackaging the 6LO data packets in a format specified for a control/management (C/M) channel associated with a communication link disposed between the DU and RU elements and operable with Common Public Radio Interface (CPRI) protocol; and

    transmitting the repackaged 6LO data packets to the RU element as a CPRI C/M message via the communication link operable with CPRI protocol, the CPRI C/M message including the address of the at least one RD element.
