Call forwarding detection in voice over packet interception
First Claim
Patent Images
1. A method performed by a network operator that sends, to an agent, required information related to a target that communicates via a communication network managed by the network operator, the method comprising:
- intercepting first messages of a first call carrying first information which indicates that the first messages of the first call are related to a first communication session engaging the target;
sending a first communication identity number, CIN, and the required information extracted from the first messages of the first call, to the agent, wherein the first CIN uniquely identifies the first communication session;
thenintercepting a second message of a forwarded call transmitted after the first messages of the first call and carrying second information, which partially differs from the first information and indicates engaging the same target;
determining whether the second message of the forwarded call is related to the first communication session, by comparing pieces of the first information with pieces of the second information;
sending the same first CIN and the required information extracted from the second message of the forwarded call to the agent, if determined that the second message of the forwarded call is related to the same first communication session; and
sending a second CIN, which is different from the first CIN, and the required information extracted from the second message of the forwarded call to the agent, if determined that the second message of the forwarded call is not related to the first communication session, wherein the second CIN uniquely identifies a second communication session, which is different from the first communication session.

10. An arrangement including a processor in a network operator configured to intercept messages transmitted to a target via a network managed by the network operator, the arrangement comprising:
-
a first module configured to intercept first messages of a first call carrying first information which indicates that the first messages of the first call are related to a first communication session engaging the target; a second module configured to send a first communication identity number, CIN, and the required information extracted from the first messages of the first call, to an agent, wherein the first CIN uniquely identifies the first communication session; a third module configured to intercept a second message of a forwarded call transmitted after the first messages of the first call and carrying second information which partially differs from the first information and indicates engaging the same target; a fourth module configured to determine whether the second message of the forwarded call is related to the first communication session, by comparing pieces of the first information with pieces of the second information; and a fifth module which is configured to send the same first CIN and the required information extracted from the second message of the forwarded call to the agent, if the fourth module determines that the second message of the forwarded call is related to the same first communication session, wherein the fifth module is further configured to send a second CIN, which is different from the first CIN, and the required information extracted from the second message of the forwarded call to the agent, if the fourth module determines that the second message of the forwarded call is not related to the first communication session, wherein the second CIN uniquely identifies a second communication session, which is different from the first communication session. - View Dependent Claims (11, 12, 13, 14, 15)

16. A non-transitory computer-readable medium configured to store executable codes, which, when executed by a computer in a network operator that sends, to an agent, required information related to a target that communicates via a communication network managed by the network operator, makes the computer perform a method comprising:
-
intercepting first messages of a first call carrying first information which indicates that the first messages of the first call are related to a first communication session engaging the target; sending a first communication identity number, CIN, and the required information extracted from the first messages of the first call, to the agent, where the first CIN uniquely identifies the first communication session;
thenintercepting a second message of a forwarded call transmitted after the first messages of the first call and carrying second information, which partially differs from the first information and indicates engaging the same target; determining whether the second message of the forwarded call is related to the first communication session, by comparing pieces of the first information with pieces of the second information; and if determined that the second message of the forwarded call is related to the same first communication session, sending the same first CIN and the required information extracted from the second message of the forwarded call to the agent, otherwise sending a second CIN, which is different from the first CIN, and the required information extracted from the second message of the forwarded call to the agent, wherein the second CIN uniquely identifies a second communication session, which is different from the first communication session. - View Dependent Claims (17, 18)
