Abstract

A monitoring apparatus and method in a mobile communication system are provided. A WGW receives information relating to a monitored subscriber from a WSS, establishes a monitoring path between the monitored subscriber and a monitoring server, upon request from the WSS, begins to monitor the monitored subscriber upon receipt of a monitoring start request from the WSS, and transmits monitored data to the monitoring server.

wherein the monitoring type information comprises information related to a context given to monitor information and the monitoring type information is stored in at least one table.

2. The monitoring method of claim 1, wherein the information relating to the monitored subscriber is at least one of an Identifier (ID) of the monitored subscriber, and information relating to a context given to monitored information.

3. A Wireless GateWay (WGW) for performing monitoring in a mobile communication system, the WGW comprising:

a communication module for communicating with another node;

a controller for receiving information relating to a monitored subscriber and monitoring type information from a Wireless Soft Switch (WSS) through the communication module, establishing a monitoring path to a monitoring server and a communication path to the monitored subscriber upon request from the WSS, monitoring the monitored subscriber according to the monitoring type information upon receipt of a monitoring start request from the WSS, and transmitting monitored data to the monitoring server, wherein the monitoring type information indicates one monitoring type from a selection of reception only monitoring, transmission only monitoring, reception and transmission monitoring, and monitoring information distribution; and

a storage unit for storing information required for monitoring the monitored subscriber and operating the controller,

wherein the monitoring type information comprises information related to a context given to monitor information and the monitoring type information is stored in at least one table.

4. The WGW of claim 3, wherein the information relating to the monitored subscriber is at least one of an Identifier (ID) of the monitored subscriber, and information relating to a context given to monitored information.

5. A monitoring method of a Wireless Soft Switch (WSS) in a mobile communication system, the method comprising:

receiving information relating to a monitored subscriber, monitoring type information, and a registration request for the monitored subscriber from a monitoring server;

registering the monitored subscriber;

notifying, when a call is created for the monitored subscriber, a Wireless GateWay (WGW) that the call is to be monitored by providing information relating to the monitored subscriber and the monitoring type information to the WGW;

requesting the WGW establish a monitoring path between the WGW and the monitoring server and a communication path between the WGW and the monitored subscriber; and

requesting the WGW to monitor the monitored subscriber according to the monitoring type information, after requesting establishment of the communication path, wherein the monitoring type information indicates at least one monitoring type from a selection of reception only monitoring, transmission only monitoring, reception and transmission monitoring, and monitoring information distribution,

wherein the monitoring type information comprises information related to a context given to monitor information and the monitoring type information is stored in at least one table.

6. The monitoring method of claim 5, wherein the information relating to the monitored subscriber is at least one of an Identifier (ID) of the monitored subscriber, and information relating to a context given to monitored information.

7. A Wireless Soft Switch (WSS) for performing monitoring in a mobile communication system, the WSS comprising:

a communication module for communicating with another node;

a controller for receiving information relating to a monitored subscriber, monitoring type information, and a registration request for the monitored subscriber from a monitoring server, registering the monitored subscriber, notifying, when a call is created for the monitored subscriber, a Wireless GateWay (WGW) that the call is to be monitored by providing information relating to the monitored subscriber and the monitoring type information to the WGW, requesting the WGW to establish a monitoring path between the WGW and the monitoring server and a communication path between the WGW and the monitored subscriber, and requesting the WGW to monitor the monitored subscriber according to the monitoring type information, wherein the monitoring type information indicates at least one monitoring type from a selection of reception only monitoring, transmission only monitoring, reception and transmission monitoring, and monitoring information distribution; and

a storage unit for storing information required for monitoring the monitored subscriber and operating the controller,

wherein the monitoring type information comprises information related to a context given to monitor information and the monitoring type information is stored in at least one table.

8. The WSS of claim 7, wherein the information relating to the monitored subscriber is at least one of an Identifier (ID) of the monitored subscriber, and information relating to a context given to monitored information.

9. A monitoring method of a monitoring server in a mobile communication system, the method comprising:

providing information relating to a monitored subscriber and monitoring type information to a Wireless Soft Switch (WSS), and requesting registration of the monitored subscriber;

establishing a monitoring path to a Wireless GateWay (WGW) for receiving monitored data of the monitored subscriber, after the WGW establishes a communication path with the monitored subscriber; and

receiving data relating to the monitored subscriber from the WGW according to the monitoring type information, wherein the monitoring type information indicates at least one monitoring type from a selection of reception only monitoring, transmission only monitoring, reception and transmission monitoring, and monitoring information distribution,

wherein the monitoring type information comprises information related to a context given to monitor information and the monitoring type information is stored in at least one table.
