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.
- 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:
- 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.
