Method and node equipment for guaranteeing service reliability in an end-to-end quality of service framework
First Claim
1. A method for guaranteeing service reliability in an end-to-end Quality of Service framework, comprising:
- checking whether connection information held in all node equipment gone through by a session connection is consistent;
if it is, finishing the consistency check;
otherwise, releasing the inconsistent connection information from every node equipment.

Abstract
A method for guaranteeing service reliability in an end-to-end Quality of Service framework, including: checking whether connection information held in all node equipment gone through by a session connection is consistent; if it is, finishing the consistency check; otherwise, releasing the inconsistent connection information from the node equipment. In this invention, consistency check is performed inside every node equipment, and between node equipment in the network, and thus, abnormal resources may be retrieved, so that network service ability will not be affected by abnormal situations. When the network is of large scope, consistency check can be done according to signaling flow sequence for establishing a session connection. When an inconsistent situation is detected, the node equipment gives a feedback to its upstream node equipment. Usually, there is a great quantity of sessions on a network, so it is better to carry out consistency check in batch for decreasing spending. With this method, degradation of service ability because of network abnormity can be avoided, and network reliability and availability can be improved, which is of great economic benefits.

13. A method for guaranteeing service reliability in an end-to-end Quality of Service framework, comprising:
-
A. selecting a piece of node equipment from all the node equipment gone through by the session connection, and sending a consistency check request to the selected node equipment;
B. the selected node equipment, which has received the consistency check request, determining whether the connection information preserved in every module of itself is consistent;
if it is, executing Step C;
otherwise, releasing the inconsistent connection information before executing Step C;
C. determining whether the consistency check request is sent from an adjacent node equipment of the selected node equipment;
if it is, returning a response message including connection information of the selected node equipment to the adjacent node equipment, and executing Step D; and
if the selected node equipment has received a response message from one of its adjacent node equipment as well, executing Step D;
otherwise, executing Step E;
D. based on the connection information carried in the received response message, the selected node equipment determining whether the connection information of itself is consistent with that of its adjacent node equipment;
if it is, executing Step E;
otherwise, releasing the inconsistent connection information held in itself, informing to release the inconsistent connection information from the adjacent node equipment, and executing Step E;
E. deciding whether there is any other adjacent node equipment of the selected node equipment that has not implemented inter-node consistency check;
if there is, sending a consistency check request to the adjacent node equipment, and executing Step B;
otherwise, ending the procedure of consistency check.

14. Node equipment for guaranteeing service reliability in an end-to-end Quality of Service framework, comprising:
-
means for determining whether connection information preserved in every module of the node equipment is consistent after receiving a consistency check request, and releasing the inconsistent connection information;
means for returning a response message including connection information of the node equipment to an adjacent node equipment when the consistency check request is sent from the adjacent node equipment; and
means for receiving a response message from the adjacent node equipment including connection information of the adjacent node equipment, determining whether the connection information of itself is consistent with that of the adjacent node equipment, and when the connection information of itself and that of the adjacent node equipment is inconsistent, releasing the inconsistent connection information held in itself, and informing the adjacent node equipment to release the inconsistent connection information.
