Abstract
In one aspect, an MME throttles (or otherwise controls) the amount or frequency of UL data that a UE transmits in the control plane, such as by communicating to the UE rate control information (e.g., a throttling factor or throttling delay). For instance, the MME may throttle NAS messages with user data (i.e., NAS Data PDUs) sent using control plane CIoT EPS optimization by adding a throttling factor and/or a throttling delay in a NAS message sent to the UE.
Claims25
A rate control method performed by a wireless communication device (WCD), the method comprising:
- the WCD transmitting a first uplink (UL) Non-Access Stratum (NAS) message toward a network entity;
- after transmitting the first UL NAS message, the WCD receiving a first downlink (DL) NAS message transmitted by the network entity towards the WCD, wherein
- the first DL NAS message transmitted by the network entity comprises first rate control information indicating a number of UL NAS messages containing user data that the WCD is permitted to send to the network entity within a first time period.
A wireless communication device (WCD), the WCD comprising:
- a transmitter for transmitting a first uplink (UL) Non-Access Stratum (NAS) message toward a network entity;
- a receiver for receiving a first downlink (DL) NAS message transmitted by the network entity towards the WCD, wherein the first DL NAS message transmitted by the network entity comprises first rate control information indicating a number of UL NAS messages containing user data that the WCD is permitted to send to the network entity within a first time period;
- and
- processing circuitry for performing rate control in accordance with the first rate control information.
A rate control method performed in a network entity handling communications with a wireless communication device (WCD) over Non-Access Stratum (NAS), the method comprising:
- determining that rate control on the number of UL NAS messages containing user data within a first time period is to be applied;
- and
- sending a message in a downlink (DL) NAS message intended for the WCD, wherein
- the DL NAS message comprises rate control information indicating the number of UL NAS messages containing user data that the WCD is permitted to be send to the network entity within the first time period.
A network entity for handling communications with a wireless communication device (WCD) over Non-Access Stratum (NAS), the network entity comprising:
- a transmitter;
- a receiver;
- and
- processing circuitry coupled to the transmitter and the receiver, wherein the network entity is configured to:
- determine that rate control on the number of UL NAS messages containing user data within a first time period is to be applied;
- and
- employ the transmitter to send a message in a downlink (DL) NAS message intended for the WCD, wherein
- the DL NAS message comprises rate control information indicating the number of UL NAS messages containing user data that the WCD is permitted to be send to the network entity within the first time period.
