Methods, systems, and computer readable media for inducing the activation of a service trigger at a switching office in a communications network are disclosed. According to one method, a call setup message associated with a call is received. It is then determined whether service trigger induction is required for the call. In response to determining that service trigger induction is required for the call, the call setup message is modified to include service trigger induction information and the modified call setup message is directed to a destination switching office. At the destination switching office, a service trigger is activated based on the service trigger induction information in the modified call setup message.

Methods, systems, and computer program products for providing variable rate prepaid telecommunication services utilizing a weighting function are disclosed. The method includes intercepting a signaling message that includes an available credit value associated with a prepaid communications session. A credit adjustment factor based on at least one call parameter associated with the prepaid communications session is determined. The method also includes applying the credit adjustment factor to the available credit value to generate an adjusted available credit value. The signaling message is modified to include the adjusted available credit value.

Methods and systems for transmitting user part messages between signaling system seven (SS7) signaling points over an internet protocol (IP) network include receiving, at a signal transfer point, a first SS7 user part message. The first SS7 user part message can be received from a first SS7 signaling point, such as a service switching point (SSP). The first SS7 signaling point is encapsulated in a first IP packet. The first IP packet is transmitted to a second SS7 signaling point over an IP network.

Methods and systems for communicating signaling system 7 (SS7) user part messages among SS7 signaling points (SPs) and internet protocol (IP) nodes using signal transfer points (STPs)

Methods, systems, and computer readable media for advertising-supported call service are disclosed. According to one method, a SIP call setup message associated with a first call from a calling subscriber to a called subscriber is received. It is then determined whether the calling subscriber subscribes to a play advertisement pay less (PAPL) service. In response to determining that the calling subscriber subscribes to the PAPL service, an advertisement is presented to the calling subscriber via the subscriber's telephone, the call is connected to the called subscriber, and a reduced charge is effected for the call based on the PAPL service.

Methods, systems, and computer readable media for providing advertising-supported call service

According to one aspect, the subject matter described herein includes a method for credit status triggered policy control. The method may include monitoring one or more credit control request (CCR) and credit control answer (CCA) messages associated with a request of credit for a subscriber. The method may further include determining whether an amount of granted credit for a service flow associated with the subscriber has reached a predetermined minimum threshold value. The method may further include notifying a policy and charging rules function (PCRF) of the credit status associated with the subscriber when the predetermined minimum threshold value has been reached.

Methods, systems, and computer readable media for diameter routing agent (DRA) based credit status triggered policy control

The subject matter described herein includes methods, systems, and computer readable media for detecting and mitigating fraud in a distributed monitoring system which includes fixed-location monitoring and communication devices. According to one aspect, a method for detecting and mitigating fraud includes receiving a signaling message that originates or appears to originate from a wireless communication device that is associated with a fixed-location management system that performs at least one of monitoring and control of a resource, wherein the wireless communication device is responsible for communicating information generated by the management system over a network. The method further includes determining whether the signaling message indicates an expected location of the wireless communication device and in response to a determination that the signaling message does not indicate an expected location of the wireless communication device, initiating a mitigating action.

Methods, systems, and computer program products for using an LRN based query and response mechanism (e.g., a switching office number portability processing system) to route calls to IP multimedia subsystem (IMS) subscribers are disclosed. According to one method, an LRN based response message including a communications service subscriber identifier is received. An IMS gateway LRN associated with the communications service subscriber identifier may be determined. The IMS gateway LRN associated with the communications service subscriber identifier may be inserted into the LRN based response message and routing the message.

Methods, systems, and computer readable media for early media connection proxying are disclosed. According to one method, a call setup signaling message is received for establishing a call between a calling entity and a called entity. Based on at least one parameter in the call setup signaling message, it is determined whether an early media connection is required for the call. It is also determined whether early media connection proxying is required for the call. In response to determining that an early media connection and early media connection proxying are required for the call, signaling is performed on behalf of a network entity to establish an early media connection for the call.

Methods, systems, and computer readable media for early media connection proxying

Methods, systems, and computer program products for providing a call attempt triggered messaging service in a communications network comprises intercepting a call signaling message including a calling party subscriber identifier and a called party subscriber identifier. A call attempt triggered message generation (CATMG) database using the called party subscriber identifier is queried. In the event the called party subscriber identifier exists in the CATMG database, a messaging service message is generated. The messaging service message is then transmitted to a contact address.

Methods, systems, and computer program products for providing a call attempt triggered messaging service in a communications network

A method for providing presence gateway functionality includes deriving presence information for subscribers in a first set of subscribers based on telecommunications signaling messages. The first set of subscribers includes at least one subscriber who is not a subscribed-to presentity. The method also includes determining whether presence status information for a subscriber in the first set of subscribers has changed. In response to detecting a change in presence status, it is determined whether the subscriber is a subscribed-to presentity. If the subscriber is a subscribed-to presentity, a presence server is notified of the change in status of the subscriber.

Methods, systems, and computer program products for surveillance of messaging service messages in a communications network are disclosed. According to one aspect, a system is provided for intercepting a messaging service message in a communications network. The system can include a communication module for receiving and sending messaging service messages from a communications network. Further, the system can include a subscriber surveillance database for maintaining a listing of subscribers that have been placed under surveillance. The system can also include a surveillance function for receiving a messaging service message, extracting a subscriber identifier from the messaging service message, performing a lookup in the surveillance database using the subscriber identifier, and performing a surveillance action in response to locating a matching entry in the database.
