Embodiment

[0218] CLAIMS 1. A method of performing load balancing by a wireless transmit / receive unit (WTRU), the method comprising evaluating a current message load value and performing load balancing by barring a current cell if the current cell load value is greater than a predetermined threshold.

[0219] 2. The method of embodiment 1, wherein barring comprises adding the current cell to a list of barred cells for a predetermined period of time.

[0220] 3. The method of embodiment 2, wherein the predetermined time period corresponds to any one of: a network-supplied value dedicated to the WTRU, a barring time for barred cells, or a barring time for barred cells part of the prohibited time.

[0221] 4. The method as in any one of embodiments 1-3, wherein the load value of the current cell is determined by the WTRU and includes any of the following: consecutive failed random access channel (RACH) connections predetermined number of access attempts; predetermined number of consecutive...

Abstract

Performing load balancing by a wireless transmit / receive unit, WTRU, includes the WTRU evaluating a current cell load value and, on a condition that the current cell load value is greater than a predetermined threshold, performing load balancing by barring the current cell. The current cell load value may be a number of consecutive failed RACH access attempts. Other embodiments teach a method to identify a machine type communication, MTC, device, a method to restrict access to a group of MTC devices, a method to restrict access to a particular MTC device, a method to control congestion, and a method for MTC device prioritization.

Description

Background technique [0001] Machine-to-machine (M2M) communication is communication between machines that does not require human intervention. This form of communication is expected to have applications in areas such as smart metering, home automation, electronic health care (eHealth), fleet management, etc. To address this potential emerging market, the 3rd Generation Partnership Project (3GPP) has started working on identifying potential network optimizations that could reduce the operational overhead associated with providing these new M2M services. [0002] According to the 3GPP definition, Machine Type Communication (MTC) involves the following entities: [0003] MTC Subscriber: A legal entity that has an agreement with a network operator to provide M2M services over a mobile network. [0004] MTC device: A wireless transmit / receive unit (WTRU) equipped for MTC communication. [0005] MTC Server: An entity that communicates directly with the mobile network or indirectl...
