20090193071 | Facilitating Deployment of New Application Services in a Next Generation Network - A disclosed application docking module (ADM) for use in a communication network includes a message monitor, an application monitor, and an anomaly handler. The message monitor monitors messages exchanged between a monitored application server and a session control layer resource of the network and the application monitor monitors a heartbeat of the application server. Based on the monitoring, the module determines when the application server is in an anomaly state. The anomaly state may indicate abnormal or otherwise unexpected application server messaging activity and/or an unexpected heartbeat status. The ADM processes application server messages on behalf of the application server when the application server is operating in an anomaly state. The ADM may, for example, block messages outgoing from the application server and process messages incoming to the application server by redirecting messages, returning messages to their sender, or generating an error code. | 07-30-2009 |
20090282137 | DISTRIBUTING USER ENDPOINT REGISTRATIONS AMONG BORDER ELEMENTS IN A NEXT GENERATION NETWORK - Disclosed methods of achieving load balancing among a plurality of border elements in a next generation networks (NGN) communication network include a method for processing and user endpoint originated messages (UEOM), such as a register or invite message, generated by a user endpoint. A work load information data structure indicative of a first border element's work load and a second border element's work load is maintained when the border elements exchange work load information. Based on the work load information, a first border element responds to a UEOM by either (1) accepting the UEOM for first border element processing, (2) determining whether to accept the UEOM for first border element processing or redirect the UEOM to a second border element for second border element processing, or (3) rejecting the UEOM. | 11-12-2009 |
20100161806 | Optimization of Media Flows in a Telecommunications System - Disclosed are techniques for optimization of media flows within a provider network. The provider network comprises a plurality of sites, each site having one or more media servers capable of supporting a media session with a user endpoint device. The provider network further includes a media server director (MSD) that receives registration information identifying one or more user endpoint devices that have registered with a particular site. Using this registration information, as well as predetermined preference policies, the MSD prepares a preference order for the media servers of the provider network for user endpoint devices associated with the site. When an application server signals an intent to establish a media session with a user endpoint device of the site, the MSD selects a media server based on the preference order and provides an indicator of the selected media server. The application server can then contact the selected media server identified by the indicator to establish and support a media session with the user endpoint device. | 06-24-2010 |
