Abstract

The present invention relates to a method and apparatus for providing application service in a mobile communication system. A method in which a base station provides application service comprises: a step of receiving a request for application service from a mobile terminal; and a step of providing the mobile terminal with the requested application service on the basis of application service information pre-stored in the base station and/or application service information received from an application server, in accordance with whether or not the application service information corresponding to the requested application service is pre-stored in the base station.

First claim

The invention claimed is:

1. A method for providing an application service at a base station (BS) in a mobile communication system, the method comprising:
receiving, by the BS, an application service request from a Mobile Station (MS);
determining, by the BS, whether a requested application service corresponding to the application service request is executable in the MS using context information of the MS stored in the BS;
creating, by the BS, a virtual terminal capable of executing the requested application service in the BS if the requested application service is not executable in the MS;
receiving, by the BS, an application program execution file and data associated with the requested application service from an application server;
executing, by the BS, the requested application service at the virtual terminal using the received application program execution file;
transmitting, by the BS, data associated with the executed application service to the MS via the virtual terminal; and
in response to identifying a decision for the MS to perform a handover to another BS, transmitting, by the BS, the context information to support the executed application service at the other BS after the handover.

2. The method of claim 1 , further comprising:
requesting verifying, by the BS, to verify whether the MS is authorized to receive the requested application service from the application server using the context information of the MS stored in the BS; and
activating, by the BS, the virtual terminal if the MS is authorized to receive the requested application service from the application server.

3. The method of claim 1 , wherein the virtual terminal operates based on an input from the MS.

4. The method of claim 1 , wherein the BS transmits the context information for supporting the executed application service to the other BS.

5. The method of claim 1 , wherein the BS transmits the context information for supporting the executed application service to the application server.

6. An apparatus configured to provide an application service in a mobile communication system, the apparatus comprising:
a Radio Frequency (RF) unit configured to communicate with a Mobile Station (MS);
a network unit configured to communicate with an application server in a network;
a memory unit configured to store application service information and context information of the MS; and
a controller configured to:
receive an application service request from the MS using the context information of the MS,
determine whether a requested application service corresponding to the application service request is executable in the MS,
create a virtual terminal capable of executing the requested application service in the apparatus if the requested application service is not executable in the MS,
receive an application program execution file and data associated with the requested application service from an application server,
execute the requested application service at the virtual terminal using the received application program execution file,
transmit data associated with the executed application service to the MS via the virtual terminal, and
in response to identifying a decision for the MS to perform a handover to another base station (BS), transmit the context information to support the executed application service at the other BS after the handover.

7. The apparatus of claim 6 , wherein the controller is further configured to request to verify whether the MS is authorized to receive the requested application service from the application server using the context information of the MS and activate the virtual terminal if the MS is authorized to receive the requested application service from the application server.

8. The apparatus of claim 6 , wherein the virtual terminal operates based on an input from the MS.

9. The apparatus of claim 6 , wherein the controller is further configured to transmit the context information for supporting the executed application service to the other BS.

10. The apparatus of claim 6 , wherein the controller is further configured to transmit the context information for supporting the executed application service to the application server.
