Abstract
Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message. In addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told by the network. Techniques may be used to indicate a network providers machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.

Claim
A method of small data communication for a wireless transmit/control unit (WTRU), the method comprising:
appending a first indication to a first message, the first indication indicating a capability of the WTRU for small data transfer capability, the small data transfer capability including the capability to send user data via a control plane;
sending, via a transmitter, the first message to a communication network;
receiving, via a receiver, a second message from the communication network, the second message including a second indication, the second indication including a capability of the communication network for the small data transfer;
appending a third indication to a third message, the third indication indicating the presence of small data in the third message; and
sending, via the transmitter, the third message to the communication network, the third message including appended small data, the small data including user data, at least the user data being sent via the control plane.
2. The method of claim 1, wherein the small data is machine type communication (MTC) small data.
3. The method of claim 1, wherein the third indication is an information element (IE).
4. The method of claim 1, further comprising:
appending a fourth indication to the third message, the fourth indication providing an indication of additional small data to be transmitted to the communication network.
5. The method of claim 1, wherein the third message is sent without the establishment of data bearers.
6. The method of claim 1, further comprising:
receiving a fourth message from the communication network, the fourth message including small data and a fourth indication, the fourth indication indicating the fourth message is a last transmission including the small data from the communication network.
7.

8. The method of claim 1, wherein the second message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
9. The method of claim 1, wherein the third message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
10. The method of claim 6, wherein the fourth message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
11. A wireless transmit/control unit (WTRU), comprising:
a receiver, the receiver configured at least to:
receive a first message from a communication network, the first message including a first indication of a capability of the communication network for small data transfer capability, the small data transfer capability including the capability to send user data via a control plane;
a processor, the processor configured at least to:
append a second indication to a second message based at least in part on the first message, the second indication indicating a capability of the WTRU for the small data transfer capability; and
a transmitter, the transmitter configured at least to:
send the second message to the communication network, the receiver being further configured to:
receive a third message from the communication network, the third message including a third indication, the third indication further indicating the capability of the communication network for the small data transfer, the processor being further configured to:
append a fourth indication to a fourth message, the fourth indication indicating the presence of small data in the fourth message, the transmitter being further configured to:
send the fourth message to the communication network, the fourth message including appended small data, the small data including user data, at least the user data being sent via the control plane.
12. The WTRU of claim 11, wherein the small data is machine type communication (MTC) small data.
13. The WTRU of claim 11, wherein the processor is further configured such that the fourth indication is an information element (IE).
14. The WTRU of claim 11, wherein the processor is further configured to:
append a fifth indication to the fourth message, the fifth indication providing an indication of additional small data to be transmitted to the communication network.
15. The WTRU of claim 11, wherein the transmitter is further configured such that the fourth message is sent without the establishment of data bearers.
16. The WTRU of claim 11, wherein the receiver is further configured to:
receive a fifth message from the communication network, the fifth message including small data and a fifth indication, the fifth indication indicating the fifth message is a last transmission including the small data from the communication network.
17. The WTRU of claim 11, wherein the receiver is further configured such that the first message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
18. The WTRU of claim 11, wherein the processor is further configured such that the second message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
19. The WTRU of claim 11, wherein the receiver is further configured such that the third message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
20. The WTRU of claim 11, wherein the processor is further configured such that the fourth message is at least one of: a system information broadcast message, a radio resource control (RRC) connection setup request, an immediate assignment message, a network access stratum (NAS) attach message, a tracking area update (TAU) message, a routing area update message, a location update accept message, or a temporary mobile subscriber identity message.
