Embodiment Construction

[0026] A detailed description of example embodiments will now be described with reference to the various drawings. Although the description provides detailed examples of possible implementations, it should be noted that the details are for purposes of illustration and do not limit the scope of the application.

[0027] Some mobile networks may be optimized for human-to-human communication and may not be optimal for machine-to-machine (M2M) communication. Support for machine type communication (MTC) may be used to accommodate requirements for machine type communication in wireless networks such as 3GPP LTE wireless networks.

[0028] Machine type communication (MTC) devices may include wireless transmit / receive units such as cellular telephones, metering devices, etc., which may not access the network as frequently as devices intended for person-to-person use. The MTC device may be a wireless sensor or the like that may be deployed to a remote area for monitoring or other task...

Abstract

Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX / Sleep cycles / periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 644,922, filed May 9, 2012, and U.S. Provisional Patent Application No. 61 / 653,706, filed May 31, 2012, the contents of which are hereby incorporated by reference . Background technique [0003] A machine type communication (MTC) device may not need to connect to a network frequently to communicate or receive data. Furthermore, the network can schedule radio resources for MTC devices on rare occasions. Therefore, MTC devices may not need to monitor the network for signals or paging as often as non-MTC devices. However, current wireless networks do not allow long discontinuous reception (DRX) cycles or sleep lengths. Contents of the invention [0004] Disclosed herein are methods and apparatus that enable wireless networks to provide long Discontinuous Reception (DRX) cycles or sleep lengths. Embodiments may allow systems and MTC devic...
