With an increasing number of friends, Peer to Peer subscription in Presence causes a great dataflow and many other issues. The Resource List Service is a very good approach to solve this problem by subscribing to the list. This paper proposes a framework for the implementation of Resource List Service Model which refers to SIMPLE standards. Based on this, the RLS as well as its descriptions are designed. Upon testing the RLS in WAN, the experimental results show that RLS can correctly complete the subscriptions of a list and provide an excellent solution for the frequent subscription issues.
