Terminating notification message for terminals in a target network area

摘要

Embodiments herein include a method of notifying terminals located in a target network area. The method is executed by a call control node. The call control node is associated with a serving network area, wherein the serving network area at least partially comprises the target network area. In order to provide an efficient, easily accomplishable, and network capacity sparing notification of terminals located in a target network area, the method comprises receiving a result of a scanning of a visitor location register database associated with the call control node for terminals registered for the target network area, and sending a notification message to the terminals located in the target network area based on the received result of the scanning.

1. A method executed by a call control node associated with a serving network area for notifying terminals located in a target network area, wherein the serving network area at least partially comprises the target network area, the method comprising:
receiving a result of a scanning of a visitor location register database associated with the call control node for terminals registered for the target network area; based on the received result of the scanning, determining which of the registered terminals are actually located in the target network area and identifying terminals that are actually located in the target network area despite not being registered in the visitor location register database; during a delivery period, sending a notification message to each of the registered terminals that are determined to be actually located in the target network area and sending a notification message to each of the unregistered terminals identified as actually located in the target network area; monitoring for terminals that enter the target network area by roaming or by executing a handover during the delivery period; and sending a notification message to any of the terminals that enter the target network area before the end of the delivery period.
