Abstract
The EPC network, a de facto standard of RFID
network, provides a variety of services including
Information Service (IS) and Discovery Service (DS),
fully utilizing today’s Internet capabilities, such as
HTTP or SOAP communication protocols and HTML
or XML contents formats. The mobile RFID network
exploits the existing cellular network infrastructure
and offers RFID-related information services to the
subscribers with cellular phones which RFID reader
chips are built in. However, in current cellular
network environment, contents are usually represented
in WML and delivered by WAP protocol, due to the
limitations such as narrow network bandwidth,
constraints in display resolution, processing power,
and memory space for hand-held phones. Inherently,
these bring the problems in information exchange
between EPC network and mobile RFID network.
In this paper, we investigate and suggest a
framework to allow EPC network as well as mobile
RFID users to seamless access the information located
in the other network. Firstly, we propose an
application level gateway which transforms the
protocols and contents formats used in EPC network
into those specially used in mobile RFID network, and
vice versa. The transformation rules may be derived by
name resolution at the local ONS installed in mobile
RFID network. Moreover, it is suggested that the
transformation rules may be automatically derived and
transparently accomplished by writing well-formed
pair of NAPTR resource records for the local ONS of
mobile network, regardless of user’s location. Finally,
an module concept for RFID applications is proposed
not only to lighten the workload of cellular phone
equipped with RFID reader and save bandwidth, but
also to accommodate the heterogeneity and evolution
of cellular phone capabilities.
