摘要:
In Machine Type Communication (MTC) with a 3GPP Long Term Evolution (LTE) Network, there is often a need to transmit and receive small data payloads. New information elements (IEs) have been defined to ease the transmission and receipt of small data payloads. Methods and systems can use the new IEs to more efficiently transmit and receive data. The new IEs include a Small Data ACK IE and a Small Data Container IE. Other new messages include an RAC Release indicator and an RRC Connection Release.

When a UE in an LTE system enters the RRC_IDLE state, only the S5/S8 EPS bearer context is retained, and the S1-U, S1-AP and radio bearers are released. These bearers have to be re-established on per UE basis when the UE returns to RRC_CONNECTED state. A number of UE applications may send small data frequently, which causes the UE to toggle between IDLE and CONNECTED states. This leads to a great deal of signaling overhead as the radio bearer and the S1-U bearer must be frequently re-established as the UE transitions between IDLE to CONNECTED states. Described herein are methods and systems that provide an always-on S1-U bearer to reduce this signaling overhead.

Embodiments for managing device trigger action requests are generally described herein. The device trigger action requests may include a recall or replacement Device-Action Request. In some embodiments, a Device-Action Request command is received at a network entry point node from an external services capability server with an action type attribute value pair set to indicate a device trigger action request for performing an action on an old device trigger request, the network entry point node determines a status of the old device trigger request from the external services capability server and the network entry point node sends a Device-Action Answer command to the external services capability server with a request-status type attribute value pair to report a status of the old device trigger request in response to the device trigger action request for performing an action on the old device trigger request.

摘要:
With the proliferation of Machine-Type Communication (MTC), an excessive use of device trigger messages in a Long Term Evolution (LTE) network can have negative effects on user equipment (UE). These effect can include a shortening of UE battery life and/or excessive signalling caused by the frequent changing from an idle mode to an active mode. An MTC Interworking Function (MTC-IWF) can be configured to determine the status of a UE to which a device trigger message is intended. If the device trigger message is low priority and the UE is in an idle state, the MTC-IWF or Mobile Management Entity (MME)/Serving GPRS Support Node (SGSN)/Mobile Switching Center (MSC) can buffer the device trigger message.
