PICO-RRU-BASED NETWORK IMPLEMENTATION FOR FACILITATING 6LOWPAN DATA ACCESS

摘要

A scheme for providing access to 6LoWPAN data in a Pico-Remote Radio Unit (PRRU)-based wireless access network. In one embodiment, the PRRU network comprises a Baseband Unit (BBU) coupled to one or more remote Radio Hub (RHUB) elements via a first set of CPRI links, each RHUB element in turn coupled to one or more PRRU elements via corresponding second sets of CPRI links. The BBU element comprises an interface for communicating 6LoWPAN data to and from a router coupled to an IPv6 network. The BBU element also includes a bridging functionality operative to determine endpoint PRRU elements' addresses and corresponding RHUB elements' addresses by querying an address mapping database.

1. A method operating at a pico remote radio unit (PRRU) element disposed in 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:
obtaining source data; determining if the source data is compliant with the 6LoWPAN format; and if so, repackaging the 6LoWPAN-compliant source data to be transmitted as upstream 6LO data signals in one or more control/management (C/M) messages of Common Public Radio Interface (CPRI) protocol operating with an Ethernet cable link disposed between the PRRU element and a remote radio hub (RHUB) element coupled thereto and providing the upstream 6LO data signals to a cable front-end (FE) block interfacing with the Ethernet cable link.
