Method and apparatus for providing edge computing service

1 . A control method for an edge computing service, comprising:

identifying a terminal corresponding to a subscriber of the edge computing service based on service authorization information of the terminal;

detecting a movement of the terminal from a first edge cluster to a second edge cluster; and

performing an action, based on the movement of the terminal, related to at least one of a first edge control server of the first edge cluster and a second edge control server of the second edge cluster,

wherein the service authorization information comprises a user equipment usage type of the terminal stored in a home subscriber server, and

wherein the user equipment usage type of the terminal corresponds to a multi-access edge computing (MEC) value predetermined and assigned to an edge control server, which is different from a network core server, by a mobile telecommunication service provider.

2 . The control method of claim 1 , further comprising performing a re-selection of a user plane device based on the movement of the terminal.

3 . The control method of claim 2 , wherein the performing the re-selection of the user plane device comprises:

based on a service state of the terminal that is an active state, delaying the re-selection until the service state becomes an idle state; and

based on the service state that is the idle state, performing the re-selection.

4 . The control method of claim 1 , wherein the detecting of the movement of the terminal comprises detecting the movement of the terminal from a first network area belonging to the first edge cluster to a second network area belonging to the second edge cluster.

5 . The control method of claim 1 , wherein the performing of the action comprises:

requesting the first edge control server to delete subscriber information of the terminal; and

transmitting the subscriber information of the terminal to the second edge control server.

6 . The control method of claim 5 , wherein the subscriber information comprises at least one of:

international mobile subscriber identity (IMSI),

an internet protocol (IP) address,

an evolved universal terrestrial access network (E-UTRAN) cell global identifier (EGCI),

a tracking area identifier (TAI),

an access point name network identifier (APNNI), and

a user equipment usage type of the terminal.

7 . The control method of claim 1 , further comprising, based on a cell change of the terminal, which is detected in the second edge cluster, notifying the cell change to the second edge control server.

8 . The control method of claim 1 , further comprising:

receiving an audit query for the terminal from a third edge control server of a third edge cluster; and

transmitting subscriber information of the terminal to the third edge control server.

9 . The control method of claim 1 , wherein the control method is performed by the network core server.

10 . A network core server comprising:

a processor; and

a memory configured to store instructions executable by the processor,

wherein, based on the instructions being executed by the processor, the processor is configured to:

identify a terminal corresponding to a subscriber of an edge computing service based on service authorization information of the terminal;

detect a movement of the terminal from a first edge cluster to a second edge cluster; and

perform an action, based on the movement of the terminal, related to at least one of a first edge control server of the first edge cluster and a second edge control server of the second edge cluster, and

wherein the service authorization information comprises a user equipment usage type of the terminal, and

wherein the user equipment usage type of the terminal corresponds to a multi-access edge computing (MEC) value predetermined and assigned to an edge control server, which is different from the network core server, by a mobile telecommunication service provider.

11 . The network core server of claim 10 , wherein the processor is further configured to perform a re-selection of a user plane device based on the movement of the terminal.

12 . The network core server of claim 11 , wherein the processor is further configured to:

based on a service state of the terminal that is an active state, delay the re-selection until the service state becomes an idle state; and

based on the service state is the idle state, perform the re-selection.

13 . The network core server of claim 10 , wherein the processor is further configured to:

request the first edge control server to delete subscriber information of the terminal, and

transmit the subscriber information of the terminal to the second edge control server.

14 . A control method for an edge computing service, comprising:

identifying a terminal corresponding to a subscriber of the edge computing service;

detecting a movement of the terminal from a first edge cluster to a second edge cluster; and

performing an action, based on the movement of the terminal, related to at least one of a first edge control server of the first edge cluster and a second edge control server of the second edge cluster;

performing a re-selection a user plane device based on the movement of the terminal,

wherein the performing the re-selection of the user plane device comprises:

based on a service state of the terminal that is an active state, delaying the re-selection until the service state becomes an idle state; and

based on the service state that is the idle state, performing the re-selection.

15 . The control method of claim 14 , wherein the detecting of the movement of the terminal comprises detecting the movement of the terminal from a first network area belonging to the first edge cluster to a second network area belonging to the second edge cluster.

16 . The control method of claim 14 , wherein the performing of the action comprises:

requesting the first edge control server to delete subscriber information of the terminal; and

transmitting the subscriber information of the terminal to the second edge control server,

wherein the subscriber information comprises at least one of:

international mobile subscriber identity (IMSI),

an internet protocol (IP) address,

an evolved universal terrestrial access network (E-UTRAN) cell global identifier (EGCI),

a tracking area identifier (TAI),

an access point name network identifier (APNNI), and

a user equipment usage type of the terminal.

17 . The control method of claim 14 , further comprising, based on a cell change of the terminal, which is detected in the second edge cluster, notifying the cell change to the second edge control server.

18 . The control method of claim 14 , further comprising:

receiving an audit query for the terminal from a third edge control server of a third edge cluster; and

transmitting subscriber information of the terminal to the third edge control server.
