Abstract: According to one aspect, the subject matter described herein includes a method for screening Diameter messages within a Diameter signaling router (DSR) having a distributed message processor architecture. The method includes steps occurring at a DSR comprising a plurality of Diameter message processors, each configured to perform at least one Diameter function. The steps include receiving, at an ingress Diameter message processor of the Diameter message processors, a Diameter message from a Diameter peer node. The steps also include identifying, at a Diameter application message processor of the Diameter message processors, a Diameter message screening rule associated with the received Diameter message. The steps further include performing, at the Diameter application message processor of the Diameter message processors, a screening function associated with the identified Diameter message screening rule on the received Diameter message.

Abstract: The subject matter described herein includes methods, systems and computer readable media for providing E.164 number mapping (ENUM) translation at a bearer independent call control (BICC) and/or session initiation protocol (SIP) router. One aspect of the subject matter described herein includes a system for providing ENUM translation. The system includes an ENUM database. The system also includes a signaling router for receiving a bearer independent call control (BICC) signaling message that includes a first call party identifier, for obtaining, from the ENUM database, a first SIP address associated with the first call party identifier, for generating a first SIP signaling message that includes the first SIP address, and for routing the first SIP signaling message to a destination SIP node.

Abstract: A method, non-transitory computer readable medium and device that determines a provider of wireless communication services includes receiving a request for wireless communication services from a computerized mobile device of a roaming user. A type of request for wireless communication services is identified. A mobile network operator is determined according to type of requested wireless communication service, location of the user, time, and availability of the requested wireless communication service. The mobile network operator is at least one of Mobile Virtual Network Operator (MVNO) or local network operator. Active elements in the determined mobile network operator are calculated. A check is made of which network elements in a home network of the user should be addressed. The home network of the user is a network of a provider of a wireless communication service where the user is registered.

Abstract: The subject matter described herein includes methods, systems and computer readable media for centralized routing and call instance code management for bearer independent call control (BICC) signaling messages. One aspect of the subject matter described herein includes a system for routing BICC signaling messages and managing call instance code assignments. The system includes a BICC signaling router. The BICC signaling router includes a routing module for centralized routing of BICC signaling messages between a plurality of BICC signaling nodes. The BICC signaling router further includes a call instance code management module for centralized assignment of call instance codes for BICC signaling sessions routed through the BICC signaling router.

Abstract: A method, non-transitory computer readable medium, and device that optimizes establishing connections to and facilitating offers of roaming services, the method includes adding, by a diameter roaming gateway controller device, a domain name of a packet data network gateway in the home network system to an update location answer received in response to an update location request from a home subscriber system in a home network system associated with a roaming mobile computing device. The update location answer is sent, by the diameter roaming gateway controller device, to a mobility management entity in a visited network. Redirect information is added, by the diameter roaming gateway controller device, to a credit control answer received from the policy charging and rules function element in the home network system in response to a credit control request message generated by a packet data network gateway in the home network system.

Abstract: According to one aspect, the subject matter described herein includes a method for managing the roaming preferences of a mobile subscriber. The method includes sending a preferred network roaming list to a mobile subscriber device. The method further includes sending a triggering message for terminating a PDP context link involving the mobile subscriber device and for activating the preferred network roaming list on the mobile subscriber device.

Abstract: According to one aspect, the subject matter described herein includes a method for Diameter-based steering of mobile device network access. The method includes receiving a Diameter message associated with a mobile device. The method also includes determining, based on the Diameter message, whether the mobile device should be steered to access a radio access network or a radio access network type that is different from a radio access network or radio access network type currently supporting network access of the mobile device. The method further includes, in response to determining that the mobile device should access the different radio access network or radio access network type, steering the mobile device to access the different radio access network or radio access network type.

Abstract: The subject matter described herein includes methods, systems, and computer readable media for dynamic subscriber profile adaptation. According to one aspect of the subject matter described herein, a method for subscriber profile adaptation is provided. The method includes receiving, from a database that stores subscriber profile information, a message generated by the database node in response to a message received by the database node. The message generated by the database node may include subscriber profile information. The method further includes determining whether to modify the subscriber profile information based on predetermined criteria. The method further includes, in response to determining to modify the subscriber profile information, modifying the subscriber profile information and forwarding the modified information to an originator of the message generated by the database node.

Abstract: According to one aspect, the subject matter described herein includes a method for providing Diameter protocol harmonization. The method includes steps occurring at a Diameter node. The method further includes determining a first Diameter protocol associated with received Diameter information that is to be sent to a destination. The method also includes determining a second Diameter protocol associated with the destination. The method further includes harmonizing the received Diameter information such that the harmonized Diameter information is compatible with the second Diameter protocol. The method also includes providing the harmonized Diameter information to the destination.
