A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling communication of small data amounts while maintaining a RRC idle mode of operation for a UE. In an example, a UE is equipped to obtain a temporary radio bearer for communication of data, that meets one or more criteria for small data transmission, over a user plane in a UMTS or LTE based network, and transmit the data, over the user plane, using the temporary radio bearer while maintaining the UE in an RRC idle mode. A UTRAN entity may receive, over the temporary radio bearer assignment, the data from a UE in an idle mode, and send the data to a SGSN using a common small data connection. The SGSN may then send the data to a PGW. |
