Abstract
A non-access stratum (NAS) control protocol includes procedures for control plane cellular internet of things (CP-CIoT) service requests and attach requests. A user equipment (UE) in idle mode may transmit an NAS service request message including user data to a mobility management entity (MME) over the control plane. The MME extracts the user data from the NAS service request message and determines a type of the user data. The MME may forward non-IP data to a Service Capability Exposure Function (SCEF) and forward IP data to a packet gateway.
Claims20
An apparatus, comprising:
- a wireless transceiver configured to communicate with a network;
- and
- processing circuitry including at least one processing device and at least one memory device, wherein at least the processing circuitry or the wireless transceiver is configured to cause the apparatus to:
- enter into an idle state without an established signaling connection to the network;
- obtain pending user data for transmission;
- insert the user data into a control plane service request message;
- and
- transmit the control plane service request message to the network using a control signaling protocol.
An apparatus, comprising:
- a network interface configured to communicate with user equipment (UE) over a network using a control plane signaling channel;
- and
- processing circuitry including at least one processing device and at least one memory device, wherein at least the processing circuitry or the network interface are configured to cause the apparatus to:
- receive a control plane service request message from the UE over the control plane signaling channel when the UE is in an idle state without an established Non-Access Stratum signaling connection to the network;
- extract user data from the control plane service request message;
- and
- forward the user data to another apparatus in the network.
User equipment (UE), comprising:
- a wireless transceiver configured to communicate with a network;
- and
- processing circuitry including at least one processing device and at least one memory device, wherein at least the processing circuitry or the wireless transceiver are configured to cause the apparatus to:
- enter into an idle state without an established signaling connection to the network;
- obtain short message service (SMS) data for transmission;
- insert the SMS data into a control plane service request message;
- and
- transmit the control plane service request message to the network using a control signaling protocol.
An apparatus, comprising:
- a network interface configured to communicate with user equipment (UE);
- and
- processing circuitry including at least one processing device and at least one memory device, wherein at least the processing circuitry or the network interface is configured to cause the apparatus to:
- receive from the UE a control plane service request message including SMS data over a control plane signaling channel, wherein the UE is in an idle state without an established Non-Access Stratum signaling connection to the network;
- extract the SMS data from the control plane service request message;
- and
- forward the SMS data to another network node.
