According to one aspect, a method for providing dynamic steering of roaming in a telecommunications network includes a method for providing dynamic steering of roaming in a telecommunications network. The method includes, at a mobile telecommunications device, the device being associated with a subscriber of a first network carrier, receiving, from a source other than an operator of the first network carrier, information identifying a second network carrier that is different from the first network carrier.

Abstract: Methods, systems, and computer readable media for 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: Methods, systems, and computer readable media for predicting imminent Diameter overload conditions using load information are disclosed. One embodiment of a system for implementing the subject matter described herein includes a first Diameter node including at least one network interface for receiving Diameter messages and a Diameter overload prediction unit. The Diameter overload prediction unit may be configured to extract load information from the Diameter messages, detect a traffic pattern using the extracted load information, predict at least one overload condition associated with one or more other Diameter nodes, and communicate an indication of the predicted overload condition to at least some of the other Diameter nodes before a time at which the overload condition is predicted to occur.

Abstract: Methods, systems, and computer readable media for determining policy information associated with an emergency call are disclosed. According to one method, the method occurs at a policy and charging rules function (PCRF) separate from an emergency services routing proxy (ESRP). The method includes receiving, from the ESRP, a request for one or more policy rules regarding an emergency call, wherein the request includes an intended destination of the emergency call and determining, using the intended destination, one or more policy rules.
