Abstract:
Methods, systems, and computer readable media for performing Diameter answer message-based network management at a Diameter signaling router (DSR) are disclosed. According to one method, a Diameter answer message that includes error indicator information is received from a first Diameter node at a DSR. The error indicator information included in the Diameter answer message is examined, at the DSR, and information based on the error indicator information is used to update status information for routes maintained by the DSR to the first Diameter node.
Abstract:
Methods, systems, and computer readable media for using a signaling message routing node to provide a backup subscriber information management service are disclosed. According to one method, a signaling message routing node obtains information associated with a subscriber. The signaling message routing node receives a first subscriber information management message including a message destination and being associated with the subscriber. The signaling message routing node determines whether the message destination is operable to process the first subscriber information management message. In response to determining that the message destination node is operable to process the first subscriber information management message, the signaling message routing node routes the first subscriber information message to the message destination. In response to determining that the message destination is not operable to process the first subscriber information management message, the signaling message routing node responds to the first subscriber information management message on behalf of the message destination.
Abstract:
According to one aspect, the subject matter described herein includes a method for providing Diameter network management information in a communications network. The method includes steps occurring at a Diameter signaling router (DSR). The method also includes determining whether successful Diameter communications are available with a first Diameter application. The method further includes in response to determining that successful Diameter communications are not available with the first Diameter application, generating a first Diameter network management message (DNMM) indicating that successful Diameter communications are not available with the first Diameter application. The method also includes sending the first DNMM to a second Diameter node.
Abstract:
Methods, systems, and computer readable media for performing triggerless mobile location-based screening and routing are disclosed. According to one aspect, the subject matter described herein includes a method for performing triggerless mobile location-based screening and routing. A telecommunications network element receives a mobility management message associated with a mobile subscriber, extracts from the mobility management message information identifying the mobile subscriber and location information associated with the mobile subscriber, and stores the extracted location information associated with the mobile subscriber. The network element receives a call setup message associated with a call from the mobile subscriber, extracts from the call setup message information identifying the mobile subscriber, retrieves the stored location information associated with the mobile subscriber, and performs a screening or routing function based on the location information associated with the mobile subscriber.
Abstract:
Methods, systems, and computer program products for communicating CNAM services for SIP originated calls terminating in a circuit switched network is described. In one embodiment, the method includes, at a SIP-SS7 gateway, receiving a SIP call setup message that includes a SIP calling subscriber identifier information, associating a temporary telephone number with the SIP calling subscriber identifier information, generating an SS7 call setup message associated with the SIP call setup message, wherein the SS7 call setup message includes the temporary telephone number, and communicating the temporary telephone number and SIP calling subscriber identifier information to a calling name interworking function (CIF) module. The method also includes, at the CIF module, storing the temporary telephone number and the associated SIP calling subscriber identifier information in a local cache, receiving a CNAM query message containing the temporary telephone number from a terminating switching office, and transmitting a CNAM response message to the terminating switching office including the SIP calling subscriber identifier information.
Abstract:
Methods, systems, and computer readable media for routing a message service message through a communications network are disclosed. In one embodiment, the method includes, at a signaling node upstream from a sending party message server, receiving a message service message that includes a sending party identifier and a receiving party identifier. A number translation database is queried to determine a routing identifier associated with the receiving party identifier. The method also includes modifying the message service message to include the routing identifier, and routing the message service message to the sending party message server.
Abstract:
Methods and systems for performing stateful signaling transactions in a distributed processing environment are disclosed. A method for performing stateful signaling transactions in a distributed processing environment includes receiving a signaling message at a routing node, such as a signal transfer point. The signaling message is distributed to one of the plurality of stateful processing modules. The receiving stateful processing module buffers the signaling message and initiates a stateful transaction based on the signaling message. Initiating the stateful transaction may include generating a query message and inserting a stateful processing module identifier in the query message. The query message is sent to an external node, such as an SCP, which formulates a response. The SCP may insert the stateful processing module in the response and send the response back to the signal transfer point. The signal transfer point decodes the response and uses the stateful processing module identifier to forward the response to the correct stateful processing module.
Abstract:
Methods and systems for providing SIP trunk groups are disclosed. A SIP call processor identifies an incoming SIP trunk group based on one or more parameters associated with an incoming SIP message. The SIP call processor selects per-trunk-group call processing data based on the incoming SIP trunk group. The SIP call processor selectively processes the call based on the per-trunk-group call processing data selected for the incoming SIP trunk group.
Abstract:
Methods and systems for generating accurate call detail records in networks that utilize number portability are disclosed. A number portability reconciliation (NPR) monitoring system receives signaling messages relating to different calls or transactions. The signaling messages may be copied from a network monitoring location upstream from where a number portability database lookup occurs for a call. The monitoring system automatically correlates messages relating to the same call or transaction into a call detail record usable by a plurality of different network monitoring applications. The NPR monitoring system determines whether number portability processing is required, and, in response, the NPR monitoring system queries a number portability database. The NPR monitoring system receives a response from the number portability database and updates the call detail record based on the response.
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.
