Abstract
A user equipment can send an EPS mobility management (EMM) message including uplink data to a network node. The user equipment can determine that an EMM process complying with the EMM message has successfully been completed or can treat an EMM process complying with the EMM message as having been successfully completed if the user equipment receives an RRC disconnection, downlink data or service acceptance message for the EMM message.
Claims18
A method for transmitting a service request by a user equipment (UE) comprising an access stratum (AS) layer and a non-access stratum (NAS) layer in a wireless communication system, the method comprising:
- transmitting, by the NAS layer, a SERVICE REQUEST message,
- wherein based on that the UE is configured to use control plane cellular internet of things (CIoT) optimization, the SERVICE REQUEST message comprises uplink user data to be transmitted via a control plane;
- and
- determining, by the NAS layer of the UE, that a service request procedure related to the SERVICE REQUEST message is successfully completed, based on that the NAS layer of the UE obtains, from the AS layer, an indication regarding a radio resource control (RRC) connection release after the transmission of the SERVICE REQUEST message,
- wherein the SERVICE REQUEST message is a non-access stratum (NAS) message.
A method for by a network node in a wireless communication system, the method comprising:
- receiving, from a user equipment (UE) which includes an access stratum (AS) layer and a non-access stratum (NAS) layer, a SERVICE REQUEST message,
- wherein based on that the UE is configured to use control plane cellular internet of things (CIoT) optimization, the SERVICE REQUEST message comprises uplink user data to be transceived via a control plane,
- performing a service request procedure related to the SERVICE REQUEST message wherein the service request procedure is successfully completed in association with a radio resource control (RRC) connection release after the reception of the service request message,
- wherein the SERVICE REQUEST message is a non-access stratum (NAS) message.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory, and
- at least one processor operating an access stratum (AS) layer and a non-access stratum (NAS) layer and coupled with the memory,
- wherein the at least one processor is configured to:
- operate the NAS layer to transmit a SERVICE REQUEST message
- wherein based on that the UE is configured to use control plane cellular internet of things (CIoT) optimization, the SERVICE REQUEST message comprises uplink user data to be transmitted via a control plane,
- operate the NAS layer to determine that a service request procedure related to the SERVICE REQUEST message is successfully completed, based on that the NAS layer of the UE obtains, from the AS layer, an indication regarding a radio resource control (RRC) connection release after the transmission of the SERVICE REQUEST message,
- wherein the SERVICE REQUEST message is a non-access stratum (NAS) message.
A network node in a wireless communication system, the network node comprising:
- a memory, and
- at least one processor coupled with the memory,
- wherein the at least one processor is configured to:
- receive, from a user equipment (UE) which includes an access stratum (AS) layer and a non-access stratum (NAS) layer, a SERVICE REQUEST message,
- wherein based on that the UE is configured to use control plane cellular internet of things (CIoT) optimization, the SERVICE REQUEST message comprises uplink user data to be transceived via a control plane,
- perform a service request procedure related to the SERVICE REQUEST message wherein the service request procedure is successfully completed in association with a radio resource control (RRC) connection release after the reception of the service request message,
- wherein the SERVICE REQUEST message is a non-access stratum (NAS) message.
