20080316931 | SYSTEM AND METHOD OF MONITORINIG NETWORK PERFORMANCE - A method of monitoring network performance is disclosed and includes receiving a session initiation protocol (SIP) response message from one of a plurality of serving-call session control function (S-CSCF) systems at a centralized error monitoring server of an Internet Protocol (IP) Multimedia Subsystem (IMS). The SIP response message includes at least one error code that matches an error monitoring initial filter criterion included in a subscriber profile. The method also includes sending an alert message to a fault management system of the IMS when at least one threshold related to SIP error codes is met or exceeded based on the at least one error code. | 12-25-2008 |
20090037573 | SYSTEM AND METHOD OF HEALTH MONITORING AND FAULT MONITORING IN A NETWORK SYSTEM - A method of monitoring a network is disclosed and includes receiving an enrollment message at a heartbeat manager from a heartbeat agent associated with a first application stored at a first network entity. The method also includes automatically associating a heartbeat interval with the first application based at least partially on the enrollment message. In another embodiment, a system of monitoring a network is disclosed and includes a network entity having processing logic and memory accessible to the processing logic. The memory stores an application including a heartbeat agent portion having instructions executable by the processing logic to enroll with a heartbeat management server communicating with the network entity and including a heartbeat monitor including instructions to subscribe to notifications indicating an operational status of an application residing at a second network entity. | 02-05-2009 |
20090138460 | System and Method of Determining Relationship Information - Systems and methods of determining relationship information are provided. A system may include processing logic and memory accessible to the processing logic. The memory may include instructions executable by the processing logic to access communication data associated with at least one first party. The memory may also include instructions executable by the processing logic to analyze a plurality of communications between the at least one first party and at least one second party to determine relationship information descriptive of a relationship between the at least one first party and the at least one second party. The communication data may include a call log and an email log, and the plurality of communications may include at least one call and at least one email message. | 05-28-2009 |
20100034085 | METHOD AND APPARATUS FOR CONTROLLING CALL VOLUME - A method and apparatus for controlling a call volume for an office that serves as a protecting site for another office in a packet network are disclosed. For example, the method collects one or more customer registration counts from one or more session border controllers located in a first office, determines if the one or more customer registration counts have reached or exceeded a threshold. The method directs all of said one or more session border controllers located in said first office to enact one or more throttling rules if the one or more customer registration counts have reached or exceeded the threshold. | 02-11-2010 |
20100124163 | Preserving Stable Calls During Failover - According to one method for preserving stable calls during failover, during a dialog between two user endpoints, a determination is made whether a standby call processor has become operational, such as when a corresponding primary call processor is in fault. Responsive to determining that the standby call processor has become operational, a signaling protocol message is received from a requester. A determination is made whether the message includes an in-dialog signaling protocol request. Responsive to determining that the message includes the in-dialog request, a determination is made whether a call state associated with the dialog is found in memory. Responsive to determining that the call state associated with the dialog is not found in memory, a non-call terminating error response is made responding to the in-dialog request. The non-call terminating error response may cause the requester to terminate the in-dialog request but not terminate the dialog. | 05-20-2010 |
20100332915 | METHOD AND APPARATUS FOR MANAGING COMMUNICATION SERVICES FOR USER ENDPOINT DEVICES - A system that incorporates teachings of the present disclosure may include, for example, an edge device having a controller to receive a Session Initiation Protocol (SIP) message from a user endpoint device (UE) requesting communication services, forward the SIP message to a network element of a Server Office, receive from the network element a first error message indicating communication services at the Server Office are unavailable, replace the first error message with a second error message, the second error message indicating a temporary unavailability of communication services, and transmit the second error message to the UE. Additional embodiments are disclosed. | 12-30-2010 |
20110026395 | Preserving Stable Calls During Failover - According to one method for preserving stable calls during failover, during a dialog between two user endpoints, a determination is made whether a standby call processor has become operational, such as when a corresponding primary call processor is in fault. Responsive to determining that the standby call processor has become operational, a signaling protocol message is received from a requester. A determination is made whether the message includes an in-dialog signaling protocol request. Responsive to determining that the message includes the in-dialog request, a determination is made whether a call state associated with the dialog is found in memory. Responsive to determining that the call state associated with the dialog is not found in memory, a non-call terminating error response is made responding to the in-dialog request. The non-call terminating error response may cause the requester to terminate the in-dialog request but not terminate the dialog. | 02-03-2011 |
20110078229 | METHOD AND APPARATUS FOR MANAGING USER ENDPOINT DEVICES IN A COMMUNICATION NETWORK - A system that incorporates teachings of the present disclosure may include, for example, a user endpoint device having a controller to submit a query to a Domain Name System (DNS) for information associated with a Fully Qualified Domain Name (FQDN) assigned to at least one of a Local Access Transport Area (LATA) or rate center of the user endpoint device, and receive from the DNS one or more descriptors of one or more session border controllers, wherein the one or more descriptors are associated with the FQDN of the user endpoint device. Additional embodiments are disclosed. | 03-31-2011 |
20120198015 | System and Method of Determining Relationship Information - A method includes classifying a relationship between a first party and each of one or more additional parties based on at least one of a number of communications between the first party and each of the one or more additional parties over a time period and a frequency of the communications between the first party and each of the one or more additional parties over the time period. The method includes generating first social network data based on the relationship between the first party and each of the one or more additional parties. | 08-02-2012 |
