Abstract: Methods, systems, and computer program products for providing telecommunication services between a SIP network and an SS7 network are disclosed. In one method, SIP/SS7 gateway receives an INVITE message from a SIP proxy server. The SIP/SS7 gateway extracts a called party number from the INVITE message and determines whether a telecommunications service is required and a type of service required for the INVITE message based on the called party number. The SIP/SS7 gateway then formulates an SS7 query to a database corresponding to the identified service type. The SIP/SS7 gateway receives a response from the database and uses data from the response to facilitate completion of the call. In one example, the SIP/SS7 gateway may forward a routing number extracted from the response back to the originating SIP proxy server. In another example, the SIP/SS7 gateway may generate a new INVITE message and forward the new INVITE message to a terminating SIP proxy server.

Abstract: Methods, systems, and computer readable media for SMS forwarding are disclosed. A message service message routing information response message containing message service message routing information for a first destination may be received. The response message is modified to direct a mobile terminated message service message intended for the first destination to the message service message proxy. The mobile terminated message service message is received at the message service message proxy, which determines whether a message service message forwarding feature is enabled for the first destination. If a message service message forwarding feature is enabled for the first destination, it is determined whether the mobile terminated message service message is eligible for forwarding to a second destination. If the mobile terminated message service message is eligible for forwarding, signaling is initiated to forward the mobile terminated message service message to the second destination.
Abstract: Systems, methods, and computer readable media for detecting and mitigating address spoofing in messaging service transactions are disclosed. A messaging service firewall (MSF) separate from a short message service center (SMSC) receives a mobility management reply message (MMR) that is sent by a mobile location register element in response to an associated mobility management query (MMQ) and that includes a serving switch identifier. The MSF allocates a global title address (GTA) from a pool of GTAs and stores a correlation between the allocated GTA and the originating SMSC. The MSF replaces the serving switch identifier in the MMR with the allocated GTA and routes the modified MMR. The MSF then receives a messaging service message (MSM) that is addressed to the allocated GTA and that includes the purported originating SMSC. If the purported originating SMSC does not match the SMSC to which the GTA is correlated, the MSM is discarded.
