Abstract: The present invention provides a session filter associated with an element to be protected in a communication network. Session requests intended for the protected element are processed by the session filter prior to being forwarded to the protected element. The protected element or a device associated therewith will provide event information indicative of undesirable session conditions, such as an overload condition, which necessitates a reduction or stoppage of incoming session requests for the protected element. The session filter will directly or indirectly receive the event information and take steps to reduce or stop the session requests being sent to the protected element. The session filter may filter the incoming session requests for the protected element and selectively send select session requests to the protected element, as well as send system protection responses to minimize the number of new session requests to devices generating or forwarding the incoming session requests.

Abstract translation: 本发明提供一种与在通信网络中要保护的元件相关联的会话过滤器。 在受保护的元素被转发之前，由会话过滤器处理针对受保护元素的会话请求。 受保护元件或与其相关联的设备将提供指示不期望的会话条件（例如过载条件）的事件信息，这需要减少或停止对受保护元件的传入会话请求。 会话过滤器将直接或间接接收事件信息，并采取措施减少或停止发送到受保护元素的会话请求。 会话过滤器可以对受保护元素的传入会话请求进行过滤，并且选择性地向受保护元素发送选择会话请求，以及发送系统保护响应以最小化向生成或转发传入会话请求的设备的新会话请求的数量。
