Abstract:
Methods, systems, and computer program products for providing presence-qualified E.164 number mapping (ENUM) service in a communications network. According to one method, a query message including an E.164 number can be received. Next, at least one uniform resource identifier (URI) associated with the E.164 number can be located. A presence server can be queried for presence status information for the URI. Further, the query message can be responded to with the URI and a corresponding presence status.
Abstract:
Methods, systems, and computer readable media tor providing sedation service in a telecommunications network are disclosed. According to one aspect, a method for providing sedation service in a telecommunications network is provided. The method includes steps that are performed at a session initiation protocol (SIP) sedation node. The method includes receiving a first message sent from a SIP user agent and intended for a SIP server. The method further includes determining whether the SIP server is unavailable. The method further includes responsive to a determination that the SIP server is unavailable to respond to the first message, sending, to the SIP client, a SIP sedation message for reducing the number or frequency of messages sent by the SIP user agent to the SIP server.
Abstract:
Disclosed is a mobility management routing (MMR) node (300) that performs location management signaling operations associated with mobile subscribers. The MMR node (300) may also perform the signaling message routing functionality typically provided by a network routing node, such as a signaling system 7 (SS7) signal transfer point (STP) or an SS7-over-Internet protocol signaling gateway (SG). The MMR node (300) caches mobile subscriber information extracted from messages transmitted between an HLR (104) and a VLR (116) and responds to some of the messages using the cached information. As a result, signaling message traffic and call setup time in a mobile communications network are reduced.
Abstract:
A filtering and application triggering platform may be implemented on a signaling message routing node (100) to decode signaling messages and increase efficiency in subsequent processing of the signaling message. A communications link module on a signaling message routing node receives a signaling message. A first filtering and application triggering module (116) associated with the communication link module (102) extracts predetermined parameters from the signaling message and generates a decode key based on the parameters. The first filtering and application triggering module (116) applies a first triggering rule to the decode key and determines whether to forward or drop the message. If the first filtering and application triggering module (116) determines that the message should be forwarded, the first filtering and application triggering module forwards the message to another processing module (106) within the signaling message routing node. The decode key is forwarded along with the message. The next processing module (106) may extract additional parameters from the message, add the parameters to the decode key, and apply a triggering rule to the modified decode key.
Abstract:
Method and systems for improving utilization of high-speed time division multiplexed communications links at a signal transfer point are disclosed. A multi-port link interface module (202) terminates two or more high-speed TDM links and generates internal data. Data received on one high-speed communications link is combined with the internal data used to fill outbound timeslots in an outgoing high-speed link. The data may include signaling data, bearer data, or signaling and bearer data.
Abstract:
Methods, systems, and computer program products for providing fault- tolerant service interaction and mediation function in a communications network are disclosed. According to one aspect, the subject matter described herein includes a method for providing fault-tolerant service interaction and mediation capability. The method includes providing an active instance of a service capability interaction manager (SCIM) function for providing service interaction and mediation between entities that request network services and entities that provide network services in a communications network. The method also includes providing a standby instance of the SCIM function. The active instance of the SCIM function performs service interaction and mediation between the entities that request network services and the entities that provide network services. In response to failure of the active SCIM function, the standby instance of the SCIM function takes over the service interaction and mediation previously performed by the active instance of the SCIM function.
