Method and apparatus for supporting communication service of idle user terminal located in common routing area in a mobile communication system
First Claim
1. A method for supporting a communication service of an idle mode terminal located in a common routing area in a mobile communication system that includes a Node B, an Access Gateway (AGW), and a Home Subscriber Server (HSS), and has a Long Term Evolution (LTE) network and a 3rd Generation (3G) network connected to each other to perform transmission/reception, the method comprising:
- receiving, by the AGW, tracking area information of the LTE network, including routing area information of the 3G network, from the idle mode terminal via the Node B;
sending, by the AGW, common routing area indication information and identification information of the terminal to the HSS if the routing area information is coincident with the tracking area information; and
storing, by the HSS, the common routing area indication information and the identification information of the terminal, and sending a response message according to the indication information.

Abstract
A method for supporting a communication service of an idle mode terminal located in a common routing area in a mobile communication system that includes a Node B, an Access Gateway (AGW), and a Home Subscriber Server (HSS), and has a Long Term Evolution (LTE) network and a 3rd Generation (3G) network connected to each other to perform transmission/reception. The AGW receives tracking area information of the LTE network, including routing area information of the 3G network, from the idle mode terminal via the Node B. The AGW sends common routing area indication information and identification information of the terminal to the HSS if the routing area information is coincident with the tracking area information. The HSS stores the common routing area indication information and the identification information of the terminal, and sends a response message according to the indication information.

5. An apparatus for supporting a communication service of an idle mode terminal located in a common routing area in a mobile communication system in which a Long Term Evolution (LTE) network and a 3rd Generation (3G) network are connected to perform transmission/reception, the apparatus comprising:
-
a Home Subscriber Server (HSS) for performing tracking area update to register routing area information of the LTE network and storing common routing area information;
an Access Gateway (AGW) for receiving, from the terminal, tracking area information of the LTE network, including routing area information of the 3G network from the idle mode terminal, comparing the routing area information with the tracking area information, and sending common routing area indication information and identification information of the terminal to the HSS if the routing area information is coincident with the tracking area information; and
the HSS for storing the common routing area information and the identification information of the terminal, and sending a response message according to the common routing area indication information. - View Dependent Claims (6, 7, 8)
