Short Messaging Service (SMS) messages are handled at a network entity of a Public Land Mobile Network (PLMN) or a device that communicates with a PLMN. An address for a Short Messaging Entity (SME) is provided in Mobile Subscriber ISDN format, comprising a Type of Number (ToN) data field, a Numbering Plan Identification (NPI) data field and a subscriber identifier field. The SME is identified as a Machine Type Communication (MTC) device based on at least one of the ToN and NPI data fields or based on a predetermined code in the subscriber identifier field. A network entity receiving the SME address can identify the SME as an MTC device and further send a message to another network entity, at least one component of the message being based on the identification. This may be applicable for human to machine communications.
