Description of Working Group:
The purpose of this group is to develop or adopt procedures, mechanisms 
and protocols to support user roaming among groups of Internet service 
providers (ISPs).  This is different from, but related to, the work of 
the IP Routing for Wireless/Mobile Hosts Working Group (mobileip) in 
that the roamops group is not concerned  with the movement of hosts or 
subnets, but of users. Thus far, the group has produced an architectural 
document describing the basic mechanisms required to support user 
roaming, a description of several existing roaming implementations and 
defined a standard username syntax to support roaming.  A repository for
documentation describing current roaming implementations is also 
In the future, the group will address interoperability among ISPs and 
roaming users by standardizing such items as network usage data exchange 
(including the content, format and protocols involved), phone book 
attributes and exchange/update protocols, authentication and 
authorization mechanisms and exploring in in depth the security issues 
involved with roaming.  This work is expected to consist mainly of new 
or revised procedures and application-layer protocols, in addition to 
recommendations for the fulfillment of the Internet roaming 
Any and all business issues regarding the operation of an ISP roaming 
network (such as settlement, business and billing methods) are 
specifically NOT in the scope of the roamops Working Group and will not 
be discussed.
The group will work closely with other IETF Working Groups (including 
mobileip, saag and cat) to identify issues to which the roamops group 
should attend, as well as to assure that their work does not make 
roaming unnecessarily difficult or impossible.
The utmost goal of the group will to make sure, by any means necessary,
that it produces documents of high quality that are useful to the IETF
