Abstract
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.
