摘要： 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.

摘要： A system that incorporates teachings of the present disclosure may utilize, for example, a method involving receiving from a first communication device a service request while providing back-up services to an out-of-service network element, detecting a deficiency in call state information to process the service request, transmitting to the first communication device an error message that prevents termination of an active Internet Protocol (IP) communication path between the first communication device and a second communication device, and receiving from the first communication device a request for an alternate IP communication path for communicating between the first and second communication devices which resolves the deficiency in call state information. Additional embodiments are disclosed.

摘要： Methods, systems, and computer-readable media for ensuring data integrity during data synchronization are provided. According to one method, a number of originating requests from a plurality of user endpoints are monitored across a network. A determination is made whether the number of originating requests is below a first threshold. Responsive to determining that the number of originating requests is below the first threshold, probe messages are transmitted to at least a portion of the plurality of user endpoints across the network. A number of the user endpoints that return probe replies in response to the probe messages are monitored. A determination is made whether the number of the user endpoints is below a second threshold. Responsive to determining that the number of the user endpoints is below the second threshold, a report is made to a database that the network is unavailable, thereby causing the database to stop updating time stamps.

摘要： System(s) and method(s) are provided for regulating interaction amongst an application layer and a control layer in a packet-based core network. A data structure is provisioned in a centralized repository; the data structure includes (i) at least one procedure for regulating interaction amongst a session control component within the control layer and application server within the application layer, and (ii) an identification (ID) field attribute that uniquely identifies the data structure. To regulate such interaction, the session control component acquires a set of provisioned data structures; acquisition is automatic and can be dictated, in part, by generation of a data structure, or modification of an existing data structure or an ID field attribute. Based at least on an ID field attribute retained in a subscriber service profile, the session control component references a data structure identified by the ID field attribute and implements one or more procedures retained in such data structure. Implementation of the one or more procedure regulates the interaction between the session control component and the application server.

摘要： A system and methodology that facilitates improving performance of a Home Subscriber Server (HSS) during overload conditions, by embedding a unique Application Session Identifier (app session ID) within multiple requests associated with a single call processing session is provided. Moreover, the system includes an overload protection component that identifies whether an incoming request is associated with previously processed requests based in part of the app session ID embedded within the incoming request. When the HSS is overloaded, the incoming requests that initiate a new call processing session and are not associated with previously processed requests are rejected/dropped before incoming requests that are associated with requests that have been previously processed.
