Description of Working Group:
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).
Aditionally - 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.
