DESCRIPTION:
Broadband Wireless Access networks address the inadequacies of low bandwidth
wireless communication for user requirements such as high quality data/voice
service, fast mobility, wide coverage, etc. The IEEE 802.16 Working Group on
Broadband Wireless Access Standards develops standards and recommended
practices to support the development and deployment of broadband Wireless
Metropolitan Area Networks. Additionally, IEEE 802.16e is an amendment that
adds support for mobility over the base IEEE 802.16 specification.
Recently, the WiMAX Forum, and, in particular, its NWG (Network Working
Group) is defining the IEEE 802.16(e) network architecture (e.g., IPv4,
IPv6, Mobility, Interworking with different networks, AAA, etc). The NWG is
thus taking on work at layers above those defined by the IEEE 802 standards
(typically limited to the physical and link layers only). Similarly, WiBro
(Wireless Broadband), a Korean effort which focuses on the 2.3 GHz spectrum
band, is also based on the IEEE 802.16e specification.
IEEE 802.16(e) is different from existing wireless access technologies such
as IEEE 802.11 or 3G. Accordingly, while 802.16 defines the encapsulation
of an IP datagram in an IEEE 802.16 MAC payload, complete description of IP
operation is not present and can benefit from IETF input and specification.
For example: immediately subsequent to network entry an 802.16 subscriber
station has no capability whatsoever for data (as opposed to management)
connectivity. The criteria by which the Base Station (or other headend
elements) set up the 802.16 MAC connections for data transport is not part
of the 802.16 standard and depends on the type of data services being
offered (ie. the set up of transport connections will be different for
IPv4 and IPv6 services). Additionally - as 802.16 is a point-to-multipoint
network - an 802.16 subscriber station is not capable of broadcasting (eg.
for neighbor discovery) or direct communication to the other nodes in the
network. While the built-in LAN emulation feature of 802.16 ("802.3
Convergence Sublayer") rectifies this, it may involve additional packet
overhead. As for fast mobility, the characteristics of IEEE 802.16e
link-layer operation may require an amendment to the Fast Handover Mobile
IPv6 scheme (RFC 4068), something which may be pursued in the MIPSHOP WG.
The principal objective of the 16ng BoF is to identify what limitations
and considerations apply to IPv6 adoption over IEEE 802.16(e), and to
propose available solutions. The working group may issue recommendations
to IEEE 802.16(e) suggesting protocol modifications for better IP support.
In 2006, WiBro deployment will begin, and the WiMAX Forum is slated to
specify IPv6 operation over IEEE 802.16(e) in 2006. Accordingly, the
working group will work and coordinate with the WiMAX Forum and with the
WiBro efforts.
