Problems solved by technology

The second issue involves creating a well-balanced event delivery structure so that the number of hops necessary to deliver a notification is limited
The third issue is ensuring that said event notifications are propagated quickly on the structure
However, their fully distributed delivery structure cannot be controlled or constrained in terms of criteria (such as geographic location of group members, bandwidth availability, and roles) that are relevant to aggregating or correlating notifications and thus improving the events system performance

Embodiment Construction

[0026] The term "event router" refers hereinafter to a network element or network node intended to forward event subscriptions and event notifications issued by an event subscriber (or corresponding event producer). The term "event router" also refers to an event subscriber or event producer. Some examples of event routers include radio base stations (RBS), mobile switching centers (MSC), base station controllers (BSC), radio network controllers (RNC), IP routers, and gateway nodes (MGW).

[0027] The term "upstream event subscription" refers hereinafter to an event subscription that is delivered to an upper event router or originates from a local event router.

[0028] The term "downstream event subscription" refers hereinafter to an event subscription transmitted from a neighboring router on the same layer or an upper layer router.

[0029] The term "upstream event notification" refers hereinafter to an event notification that is delivered to an upper layer event router or ...

Abstract

A method of processing event subscriptions in a telecommunications or data network comprising a plurality of nodes organized in clusters, in multiple layers. Each cluster has a cluster leader. The method comprises maintaining by each node a routing table comprising a list of nodes in its cluster and a repository of event subscriptions; forwarding an ascending subscription by a node to all nodes within its cluster and to its cluster's leader; forwarding a descending subscription to all nodes of all layers that the node is a leader and adding a received event subscription to the event subscriptions repository and associating said subscription with a node, which forwarded it.

Description

technical field [0001] The present invention relates generally to telecommunications and data networks, and in particular to handling event notification and event subscriptions in telecommunications and data networks. Background technique [0002] In prior art solutions, event notifications are managed in a centralized manner, i.e. around one (or several) Generated event related information. This centralized management paradigm is characterized by the concentration of application processing and traffic on a single network application, while the collection of agents is restricted to the role of dumb event collectors. Due to the increase in network size, there is a tendency to relieve the load on the central management station by delegating some of the workload to agents, as suggested by the 3GPP Long Term Evolution process. These agents are software entities running on remote NEs that perform event handling related tasks on behalf of the central manager. [0003] One popul...
