Description of Working Group:
The Mobile IP Working Group has developed routing support to permit IP nodes (hosts and routers) using either IPv4 or IPv6 to seamlessly "roam" among IP subnetworks and media types. The Mobile IP method supports transparency above the IP layer, including the maintenance of active TCP connections and UDP port bindings. Where this level of transparency is not required, solutions such as DHCP and dynamic DNS updates may be adequate and techniques such as Mobile IP not needed.
The WG moving forward will focus on deployment issues in Mobile IP and provide appropriate protocol solutions to address known deficiencies and shortcomings. For example, the wireless/cellular industry is considering using Mobile IP as one technique for IP mobility for wireless data. The working group will endeavor to gain an understanding of data service in cellular systems such as GPRS, UMTS, CDMA2000, and interact with other standards bodies that are trying to adopt and deploy Mobile IP WG protocols in these contexts. In order to provide a complete solution and a set of protocols that can be used as a roadmap for widespread deployment, the following work needs to be accomplished by this WG. In the near term, the WG needs to work on:
- Use of NAIs to identify mobile users/nodes.
- Specifying how Mobile IP should use AAA functionality to support inter-domain and intra-domain mobility.
- Evolve the security framework/trust model for mobile nodes.
- Develop solutions for IPv4 private address spaces for the scenarios needed for deployment.
- Documenting any requirements specific to cellular/wireless networks.
In the longer term, the WG needs to address:
- Additional IP-based solutions for micro mobility (movement within a subnet).
- QoS in the mobile IP environment using diff-serv and/or int-serv/RSVP.
- Location Privacy.
The Working Group will ensure that solutions proposed for these problem domains are suitable for IPv4 and IPv6 respectively.
