A Framework for IM Interworking with Heterogeneous Networks

Instant messaging is a very popular service in wire and wireless networks. Also, numerous IM communities have been created ,and multiple operators in the world have developed platforms supporting IM services in different environments. Therefore, IM interworking between heterogeneous networks is considered to be a major step in order to enlarge IM communities ; however, no architecture specifies any requirements for interconnecting between IM operators. The purpose of this article is to create a framework for IM interworking with heterogeneous networks. We suggest the IMH (IM Hub) framework and will explain the interconnecting call flow.
