Method and apparatus of communicating machine type communication data over an Iu interface in a universal mobile telecommunications system

摘要

The present invention provides a method and apparatus for communicating machine type communication (MTC) data across an Iu interface in an universal mobile telecommunications system (UMTS) network environment. In one embodiment, PDUs associated with one or more MTC devices are aggregated by a radio network controller. Then, 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-PS interface that connects the radio network controller and the core network.
