METHOD, DEVICE AND SYSTEM FOR RELEASING RESOURCE AFTER NETWORK ELEMENT RESTARTS

摘要

The present invention belongs to the field of computer communication and mainly relates to a method, device and system for releasing resource after a network element restarts. The method comprises: a second network node receives an ability exchange request from a first network node and the ability exchange request carries a first original state identifier; a second original state identifier, which is corresponding to the first network node and stored in the second network node, is compared with the first original state identifier; if the identifiers are different, a session ending request is transmitted to a third network node and the session ending request carries the first network node identifier and a restart identifier. Therefore, the waste in network passages caused by abnormal restart of the first network node is reduced.
