Title:
METHOD AND APPARATUS FOR NON-ACCESS STRATUM TRANSPORT
Document Type and Number:
WIPO Patent Application WO/2019/158097
Kind Code:
A1
Abstract:
Aspects of the disclosure can provide an apparatus and method for communicating with core network of a fifth generation system. The method includes transmitting, by a processing circuitry of a user equipment, a non-access stratum transport message to the core network to initiate a non-access stratum transport procedure with the core network, and receiving an indication message from the core network when a network function of the core network is unable to process the non-access stratum transport message, wherein the indication message includes at least one of a payload type, a cause value, and timer information. When the payload type of the indication message is a fifth generation system session management message, a short message service message or a long term evolution positioning protocol message, the processing circuitry of the user equipment performs at least one of: re-initiating a non-access stratum transport procedure based on timer information, aborting the non-access stratum transport procedure, and releasing a protocol data unit session.
