METHODE AND SYSTEM FOR MANAGING NETWORK NODES OVERLOAD

A method for managing a network node overload and a communication network system thereof, wherein upon transferring to a network entity (i.e., the RNC or CN entity) at least one or more information elements by being included in a certain message through an Iu interface (or an IuFlex interface) which connects an RNC with a CN entity, the network entity having received the certain message performs a particular algorithm (i.e., an algorithm corresponding to the certain message) to control a signaling load between the RNC and the CN entity, thereby preventing in advance and managing an overload of a certain network node.
