Abstract
The invention relates to a test arrangement and a test method in a node of a communication network for testing communication connections to other modes in the communication network, in which test messages (SLTM) are sent to the partner nodes and an evaluation of the communication connections to the partner nodes is made on the basis of the received replies (SLTA) from the partner nodes to the sent test messages (SLTM). To prevent erroneous interpretations, internal system information on the nodes, for example, data losses during the test as a result of a buffer memory overflow, are taken into account during the evaluation.
Claims10
A test arrangement in a node of a communication network for testing communication connections to other nodes in the communication network, comprising:
- a transmit unit for sending test messages to a B-node;
- a receive unit for receiving a response from the B-node to the sent test message;
- and
- a control unit for evaluating the communication connection to the B-node on the basis of the received response and for initiating clearance of the communication connection to the B-node,
- wherein the control unit checks, in the absence of a response from the B-node to the sent test message, whether a data loss has occurred within the node during the test, and does not initiate clearance of the communication connection if a data loss has been detected.
A test method in a node of a communication network for testing communication connections to other nodes in the communication network, comprising:
- sending a test message to a B-node;
- receiving a response from the B-node to the sent test message;
- evaluating the communication connection to the B-node on the basis of the received response;
- and
- initiating clearance of the communication connections to the B-node if the evaluation produces a negative result,
- wherein in the absence of a response from the B-node to the sent test message, a check is made to see whether a data loss has occurred within the node during the test, and clearance of the communication connection is not initiated if a data loss has been detected.
