METHOD AND APPARATUS OF COMMUNICATING MACHINE TYPE COMMUNICATION DATA OVER AN IU INTERFACE IN A UNIVERSAL MOBILE TELECOMMUNICATIONS SYSTEM

摘要

A method and an apparatus for communicating Machine Type Communication (MTC) data across an Iu interface in a Universal Mobile Telecommunications System (UMTS) network environment are provided. The apparatus includes Packet Data Units (PDUs) associated with one or more MTC devices are aggregated by a radio network controller. The aggregated PDUs associated with the one or more MTC devices are concatenated into an Iu PDU based on a Radio Access Bearer (RAB) identifier associated with the one or more MTC devices. The Iu PDU including the aggregated PDUs is transmitted to a core network across an Iu-Packet Switched (PS) interface that connects the radio network controller and the core network.
