Abstract
Methods of operating a network function NF node of a communication network are discussed. In such methods a message is received from an access and mobility management function AMF node. Moreover, the message includes information regarding a radio access network RAN node with respect to a communication device. Related methods of operating RAN nodes and AMF nodes are also discussed.
Claims19
A method of operating a network function, NF, node of a communication network, the method comprising:
- transmitting an association service request message to an access and mobility management function, AMF, node, wherein the association service request message includes an identifier of a communication device;
- receiving an association service response message from the AMF node after transmitting the association service request message, wherein the association service response message includes information regarding a radio access network, RAN, node with which a communication device is connected;
- and
- providing communication between the NF node and the RAN node with which the communication device is connected using the information regarding the RAN node.
1 more element
A network function, NF, node comprising:
- processing circuitry;
- and
- memory coupled with the processing circuitry, wherein the memory includes instructions that when executed by the processing circuitry causes the NF node to,
- transmit an association service request message to an access and mobility management function, AMF, node, wherein the association service request message includes an identifier of a communication device;
- receive an association service response message from the AMF node after transmitting the association service request message, wherein the association service response message includes information regarding a radio access network, RAN, node with which a communication device is connected;
- and
- provide communication between the NF node and the RAN node with which the communication device is connected using the information regarding the RAN node.
