Abstract
The invention describes a method for dynamic switching between a control plane data transmission and user plane data transmission avoiding the Detach and consecutive re-attach procedure or TAU procedure. In particular the decision for switch between the different transmission schemes is based on various criteria like the size of the data packet or on total amount of data, etc.
Claims11
A core network node, comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- determine, in a case where transmission of first data using a Control Plane Cellular Internet of Things (CIoT) Optimization is performed, whether further data is transferred via User Plane or not, based on data size of second data transmitted after transmission of the first data,
- transmit a request for setup of a User Plane radio resource for a mobile terminal, to a radio access network node based on the determining,
- receive a message for notifying completion of setup of the User Plane radio resource for the mobile terminal, from the radio access network node, and
- transmit a modification request including tunnel information to a network node for data transfer, for data transfer using the User Plane radio resource.

A controlling method for communication, comprising:
- determining, in a case where transmission of first data using a Control Plane Cellular Internet of Things (CIoT) Optimization is performed, whether further data is transferred via User Plane or not, based on data size of second data transmitted after transmission of the first data;
- transmitting a request for setup of a User Plane radio resource for a mobile terminal, to a radio access network node based on the determining;
- receiving a message for notifying completion of setup of the User Plane radio resource for the mobile terminal, from the radio access network node;
- and
- transmitting a modification request including tunnel information to a network node for data transfer, for data transfer using the User Plane radio resource.

A radio access network node, comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- receive a request for setup of a User Plane radio resource for a mobile terminal, including a User Plane Cellular Internet of Things (CIoT) indication indicating whether User Plane CIoT Optimization is supported or not, from a core network node,
- set a User Plane radio resource for a mobile terminal, and
- transmit a message for notifying completion of setup of the User Plane radio resource for the mobile terminal, to the core network node.

A communication method, comprising:
- receiving a request for setup of a User Plane radio resource for a mobile terminal, including a User Plane Cellular Internet of Things (CIoT) indication indicating whether User Plane CIoT Optimization is supported or not, from a core network node;
- setting a User Plane radio resource for a mobile terminal;
- and
- transmitting a message for notifying completion of setup of the User Plane radio resource for the mobile terminal, to the core network node.
