Method and apparatus for group management for group event monitoring

A method for managing an event monitoring for a group of terminals in a wireless communication system performed by a second network function entity, the method comprising:

• receiving, from an application function entity associated with a configured monitoring event, a first monitoring request message for modifying the configured monitoring event, the first monitoring request message including a first configuration identifier corresponding to the configured monitoring event, an operation of group management for the group of terminals, and a terminal identifier indicating a terminal associated with the operation;
• and
• transmitting, to a first network function entity, a second monitoring request message based on the first monitoring request message, the second monitoring request message including a second configuration identifier corresponding to the configured monitoring event, the operation and the terminal identifier,
• wherein the second configuration identifier, the operation, and the terminal identifier are stored at the first network function entity based on the first monitoring request message,
• wherein the configured monitoring event is updated for the indicated terminal based on the operation,
• wherein information for modifying the configured monitoring event is transmitted to a third network function entity associated with the indicated terminal from the first network function entity based on the second monitoring request message, the information including the second configuration identifier and the terminal identifier, and
• wherein the operation includes at least one of an addition of the terminal to the group or a deletion of the terminal from the group.

A first network function entity for managing an event monitoring for a group of terminals in a wireless communication system, the first network function entity comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from a second network function entity, a monitoring request message for modifying a configured monitoring event, the monitoring request message including a configuration identifier corresponding to the configured monitoring event, an operation of group management for the group of terminals, and a terminal identifier indicating a terminal associated with the operation,
• store the configuration identifier, the operation, and the terminal identifier based on the monitoring request message,
• update the configured monitoring event for the indicated terminal based on the operation, and
• transmit, to a third network function entity associated with the indicated terminal, information for modifying the configured monitoring event, the information including the configuration identifier and the terminal identifier,
• wherein the operation includes at least one of an addition of the terminal to the group or a deletion of the terminal from the group.

A second network function entity for managing an event monitoring for a group of terminals in a wireless communication system, the second network function entity comprising:

• a transceiver;
• and
• a controller configured to:
• receive, from an application function entity associated with a configured monitoring event, a first monitoring request message for modifying the configured monitoring event, the first monitoring request message including a first configuration identifier corresponding to the configured monitoring event, an operation of group management for the group of terminals, and a terminal identifier indicating a terminal associated with the operation, and
• transmit, to a first network function entity, a second monitoring request message based on the first monitoring request message, the second monitoring request message including a second configuration identifier corresponding to the configured monitoring event, the operation and the terminal identifier,
• wherein the second configuration identifier, the operation, and the terminal identifier are stored at the first network function entity based on the monitoring request message,
• wherein the configured monitoring event is updated for the indicated terminal based on the operation,
• wherein information for modifying the configured monitoring event is transmitted to a third network function entity associated with the indicated terminal from the first network function entity based on the second monitoring request message, the information including the second configuration identifier and the terminal identifier, and
• wherein the operation includes at least one of an addition of the terminal to the group or a deletion of the terminal from the group.
