Abstract
An IP-to-PLMN gateway (IPG) enables extension of the PLMN messaging domain into IP domains. Enhanced service functions in a PLMN (such as store and forward, message waiting) are carried over into the messaging service available in the IP domains. The IPG has an SME interface which interfaces on the mobile network side with an SMSC. A presence management function detects and maintains data relating to presence status of users in the IP domain.
