Abstract

A method and Network function for controlling an operation of a device based on a service provided to the device is provided. The method includes obtaining at least one of information about the service requested by the device, movement information of the device, or capability information of the device, determining a characteristic of the service provided to the device based on at least one of the information about the service, the movement information of the device, or the capability information of the device, generating service setting information for the service provided to the device based on the determined characteristic of the service, and transmitting, to an Access and Mobility Function (AMF), the service setting information.

First claim

What is claimed is:

1. A method of controlling, by a Central Mobility Manager (CMM), an operation of a device based on a service provided to the device, the method comprising:
receiving, from an Access and Mobility Function (AMF), a request to generate information related to mobility for restricting cell switching, the request including at least one of information about the service requested by the device, movement information of the device, or capability information of the device;
determining a characteristic of the service provided to the device based on at least one of the information about the service, the movement information of the device, or the capability information of the device;
generating the information related to mobility for restricting cell switching with respect to the service provided to the device based on the determined characteristic of the service and a network slice; and
transmitting, to the AMF, the information related to mobility for restricting cell switching.

2. The method of claim 1 ,
wherein the information about the service requested by the device comprises Network Slice Selection and Assistance Information (NSSAI), and
wherein the movement information of the device comprises at least one of source information of the device, destination information of the device, current location information of the device, or movement route of the device.

3. The method of claim 1 ,
wherein the information related to mobility comprises at least one of information about a mobility procedure, information about whether to permit the mobility procedure for the device, allowed frequencies for the device, a list of Tracking Areas (TAs) of the device, a list of preferred cells of the device, or type of Radio Access Technologies (RATs) of the device.

4. The method of claim 3 ,
wherein the information about the mobility procedure comprises at least one of cell reselection, cell redirection, a neighboring signal cell measurement event, a location update, carrier aggregation, Wireless Fidelity (Wi-Fi) aggregation, or handover for the device, and
wherein the information about the mobility procedure is generated based on the movement information of the device when the service requested by the device is provided to the device through a network slice.

5. The method of claim 1 , wherein the generating of the information related to mobility for restricting cell switching with respect to the service provided to the device comprises:
receiving current location information of the device to which the service is provided,
determining a cell to perform cell reselection or handover for the device from among the cells included in a list of tracking areas (TAs) or a list of preferred cells based on the current location information, and
generating the information related to mobility based on the determination.

6. The method of claim 1 , wherein the generating of the information related to mobility for restricting cell switching with respect to the service provided to the device comprises:
generating the information related to mobility by further considering the capability information of the device and Network Slice Selection and Assistance Information (NSSAI) of the device, which are received from the AMF.

7. The method of claim 1 , wherein the information related to mobility is generated by further considering a radiation pattern of a radio cell.

8. The method of claim 1 ,
wherein the determining of the characteristic of the service provided to the device comprises:
predicting an amount of movement of the device according to the characteristic of the service, and

wherein the generating of the information related to mobility for restricting cell switching with respect to the service provided to the device comprises:
determining a list of tracking areas (TAs) of the device based on the predicted amount of movement, and generating the information related to mobility based on the determined list of TAs.

9. The method of claim 1 , wherein the transmitting, to the AMF, of the information related to mobility comprises:
transmitting the information related to mobility through a message having a format corresponding to the characteristic of the service.

10. The method of claim 1 , further comprising:
predicting an amount of movement of the device based on the determined characteristic of the service,
wherein the information related to mobility for the service provided to the device is generated based on the determined characteristic of the service, the network slice, and the predicted amount of movement.

11. A Central Mobility Manager (CMM) of controlling an operation of a device based on a service provided to the device, the CMM comprising:
a transceiver;
at least one processor; and
a memory configured to store instructions that, when executed by the at least one processor, cause the at least one processor to:
receive, from an Access and Mobility Function (AMF), a request to generate information related to mobility for restricting cell switching, the request including at least one of information about the service requested by the device, movement information of the device, or capability information of the device,
determine a characteristic of the service provided to the device based on at least one of the information about the service, the movement information of the device, or the capability information of the device,
generate the information related to mobility for restricting cell switching with respect to the service provided to the device, based on the determined characteristic of the service and a network slice, and
control the transceiver to transmit, to the AMF, the information related to mobility for restricting cell switching.

12. The CMM of claim 11 ,
wherein the information about the service requested by the device comprises Network Slice Selection and Assistance Information (NSSAI), and
wherein the movement information of the device comprises at least one of source information of the device, destination information of the device, current location information of the device, or a movement route of the device.

13. The CMM of claim 11 ,
wherein the information related to mobility comprises at least one of information about a mobility procedure, information about whether to permit the mobility procedure for the device, allowed frequencies for the device, a list of Tracking Areas (TAs) of the device, a list of preferred cells of the device, or type of Radio Access Technologies (RATs) of the device.

14. The CMM of claim 13 ,
wherein the information about the mobility procedure comprises at least one of cell reselection, cell redirection, neighboring signal cell measurement event, location update, carrier aggregation, Wireless Fidelity (Wi-Fi) aggregation, or handover for the device, and
wherein the information about the mobility procedure is generated based on the movement information of the device when the service requested by the device is provided to the device through a network slice.
