Embodiment Construction

[0020] Referring now to the accompanying drawings, figure 1 An exemplary wireless communication network 10 is shown. The communication network 10 may, for example, comprise a mobile communication network 12 operating according to any standard employing a contention-based Random Access Channel (RACH). For illustrative purposes, an exemplary embodiment of the invention will be described in the context of a network operating in accordance with the GSM / EDGE (Global System for Mobile Communications (GSM) Packet Radio Service) standard. However, those skilled in the art will appreciate that the present invention is more generally applicable to other wireless communication systems, including Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX) systems. The mobile communication network 10 includes: a core network 12 connected to an external packet data network 14 (such as the Internet); and a plurality ...

Abstract

A device type-dependent approach to access control is used to independently control network access by machine-type communication (MTC) and non-MTC devices. A plurality of access classes are defined for each device type. The base station selectively controls access to the network by each device type by sending an access control mask for each defined device type to the wireless terminals within the network.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Patent Application 61 / 317910, filed March 26, 2010, which is hereby incorporated by reference. technical field [0003] The present invention relates generally to access control in mobile communication networks, and more particularly to access control of machine type wireless terminals. Background technique [0004] A Random Access Channel (RACH) in a mobile communication network provides contention-based access to wireless terminals to request connection establishment when no radio resources are allocated to the wireless terminals. In a system based on the GSM / EDGE standard, a wireless terminal sends an access request message to the network on the RACH. Because of security and to minimize the amount of information sent by the wireless terminal to accomplish contention resolution, the Access Request message includes a randomly generated reference value for identification purposes – suc...
