Abstract
Disclosed is a control function transfer technology that moves/loads a control function, contained in a network node (NF), into another NF, so that signalings among respective NFs which occur during signaling processing associated with a UE may be reduced and a delay in signaling processing with respect to the UE may be reduced.
Claims17
A network system, comprising:
- a plurality of network nodes configured to contain at least one control function;
- and
- a control node configured to load a predetermined control function of a predetermined network node into another network node selected from the plurality of network nodes, the predetermined network node being required to separate a control function.
A network device, comprising:
- a control function unit configured to contain at least one control function;
- a separation unit configured to separate a predetermined control function based on user context information from the at least one control function;
- and
- a controller configured to provide at least one of the predetermined control function and the user context information to a control node, so that the predetermined control function is loaded into another network device, which is selected by the control node based on the user context information.
1 more element
A network device, comprising:
- a control function unit configured to contain at least one control function;
- and
- a controller configured to obtain a predetermined control function separated from another network device based on user context information and load the predetermined control function of the another network device into the network device,
- wherein each control function of the control function unit is configured to transfer a predetermined signaling associated with the user context information which is to be transmitted to the predetermined control function of the another network device to the predetermined control function of the controller, so as to enable the predetermined signaling to be processed in the network device.
1 more element
An operation method of a network device, the method comprising:
- separating a predetermined control function based on user context information from at least one control function;
- and
- providing at least one of the predetermined control function and the user context information to a control node, so that the predetermined control function is loaded into another network device selected by the control node based on the user context information.
An operation method of a network device, the method comprising:
- containing at least one control function in advance;
- obtaining a predetermined control function based on user context information from another network device and loading the predetermined control function of the another network device into the network device;
- and
- transferring, by the at least one control function, a predetermined signaling associated with the user context information which is to be transferred to the predetermined control function of the another network device to the predetermined control function of the network device, so that the predetermined signaling is processed in the network device.
