  • Patent number: 8831202
    Abstract: Computer readable media and methods are provided for initiating a failover state in a network element. A failover is when the element's traffic is routed to a redundant element which takes over the functions of the element, and any session state information stored in the element is also transferred to the redundant element. If a failover occurs with an upstream element, a downstream element is not aware of the failover and does not transfer its session state information to its redundant element. By maintaining a database of historic usage information, the downstream element can determine that an upstream failover has occurred when the amount of data it is processing drops below a minimum usage threshold. The minimum usage threshold is based on the historical usage data and a relationship between a given time in the past and the current time.

  • Patent number: 8804937
    Abstract: A ring-back tone generator system receives an inbound call connection request forwarded from a phone switch (such as an MSC) that receives the inbound call connection request from a caller phone attempting to connect to a target phone (e.g., a subscriber). The ring-back tone generator system initiates generation of a first call connection on which to provide the customized ring-back tone (and/or custom video image data) to the caller phone. The ring-back tone generator system also transmits, based on receiving the inbound call connection request, an outbound call connection request to the phone switch (such as the MSC) to establish a second call connection through the phone switch to the target phone. Consequently, an MSC that normally handles such call processing now relies on the ring-back tone generator system to handle call processing and provide a custom ring-back tone service.

A failover is when the element's traffic is routed to a redundant element which takes over the functions of the element, and any session state information stored in the element is also transferred to the redundant element. If a failover occurs with an upstream element, a downstream element is not aware of the failover and does not transfer its session state information to its redundant element. By maintaining a database of historic usage information, the downstream element can determine that an upstream failover has occurred when the amount of data it is processing drops below a minimum usage threshold. The minimum usage threshold is based on the historical usage data and a relationship between a given time in the past and the current time.

  • Patent number: 8223926
    Abstract: Registering with a call manager includes connecting to a first call manager and a second call manager. The endpoints register with the first call manager and send keep-alive signals to the first call manager and the second call manager. If a failure is detected in the first call manager, the system initiates a failover process. The endpoints re-register with the first call manager when the first call manager regains operability.

  • Patent number: 8218740
    Abstract: A signaling node within a telecommunications network automatically detects that a signaling link is fluctuating in and out of service and provides hysteresis to the fluctuating signaling link. The signaling node includes a link controller that monitors the state(s) of the signaling link over a time period and a link blocking module that blocks the signaling link from carrying SS7 traffic when the signaling link fluctuates between a failed state and a stable state over the time period.

  • Patent number: 8170187
    Abstract: A system for (and a method of) selectively establishing communication with one of plural devices associated with a single telephone number during a disaster or disaster recovery period. In a preferred embodiment, the system includes two wireless connection units, each connected between a respective private branch exchange (PBX) network and a public switched telephone network. Each wireless connection unit preferably serves as a gateway between its respective PBX network and one or more remote communication devices. The wireless connection units replicate each others databases. In the event of a disaster that destroys or renders one of the wireless connect/PBX networks inoperable, telephone calls destined for the inoperable network are seamlessly routed to the operable wireless connect/PBX network. Since the operable wireless connection unit contains information for both networks, inbound, outbound and extension to extension calls for each network can be handled despite the disaster.

  • Patent number: 8150007
    Abstract: A system provides redundant telephone call processing. A gateway receives a call and identifies a first server as having primary responsibility for servicing the call and a second server as having secondary responsibility for servicing the call. The gateway communicates the call to both the first server and the second server. The first server initiates recording of a voice message. The first server and the second server record the voice message. If the first server fails to indicate it has completed and stored the voice message in a timely manner, the second server stores the recorded voice message.

  • Patent number: 8099504
    Abstract: A radio network controller and methods for reestablishing sessions in a wireless network are described. At least a portion of session information associated with a first session is saved; and in response to detecting an unexpected degradation of the first session, reestablishment of the first session is triggered using the portion of the session information.

  • Patent number: 8094568
    Abstract: A method and system for transmitting data corresponding to at least one endpoint device problem in a packet communications network is described. Specifically, an endpoint device detects at least one problem that pertains to the endpoint device. The endpoint device then generates data pertaining to the endpoint device problem. Lastly, the endpoint device then transmits the data detailing that endpoint device problem to the packet communications network.

  • Patent number: 8059798
    Abstract: Method and apparatus for ad hoc cooperative routing in an IP network. Included is an emergency stand alone (ESA) system that provides a bypass to a failed TDM switch for multiple communication devices in communication with one or more TDM switches. One or more internet protocol media gateways communicate a multicast signal upon the failure of a switch. The multicast initiates Voice over IP communication between endpoints, bypassing the failed switch.

  • Patent number: 8045686
    Abstract: The preferred embodiments described herein include a system and method for providing a backup-restore solution for active-standby service management systems. In one embodiment, a telecommunication system is disclosed having first and second service management systems (SMS), a storage device shared by the first and second SMSs and circuitry operative to provide backup/restore functionality. This provides system redundancy in that the second SMS can perform the same functions as the first SMS in the event that the first SMS is unavailable due to, for example, system failures, a scheduled maintenance, or an upgrade process. Other embodiments are provided, and each of the embodiments described herein can be used alone or in combination with one another.
