  • Method for preventing the delivery of short message service message spam
    Patent number: 7996024
    Abstract: Methods, systems, and computer program products for delivery of SMS messages are disclosed. According to one method, first routing data for delivery of an SMS message to a mobile terminal is received at a network element. Second routing data is transmitted from the network element in response to receiving the first routing data. An SMS message having the second routing data is received at the network element. The second routing data is converted at the network element to the first routing data for delivery of the SMS message to a mobile terminal. The network element uses the first and second routing data to correlate a request for the first routing data with receipt of the SMS message. The network element compares an SMSC address in the request for the first routing data with an SMSC address in the SMS message to detect the presence of address spoofing.

  • Methods and systems for converting an internet protocol (IP)-based message containing subscriber content to a public switched telephone network (PSTN)-based message including subscriber content
    Patent number: 7983245
    Abstract: A node in a converged network converts a session initiation protocol (SIP) message to a signaling system 7 (SS7) message. A SIP INVITE request is received by the node and the node determines whether the SIP INVITE request is destined for an SS7 user. If the INVITE request is destined for an SS7 user, the node determines whether the INVITE request contains MIME-encoded text and constructs a short message service (SMS) message containing the MIME-encoded text. The SMS message is routed to the SS7 user. In addition, the node constructs an initial address message (IAM) and routes the IAM to the SS7 user.

  • Methods, systems, and computer program products for processing mobile originated query messages for prepaid mobile subscribers in a number portability environment
    Patent number: 7936866
    Abstract: Methods, systems, and computer program products for routing query messages associated with prepaid subscribers in a number portability environment are disclosed. One method may include sending a registration message to an HLR. At the HLR, the ID or address of an STP is inserted as the prepaid SCP ID in a registration response message. The registration response message is sent to the MSC/VLR that originated the registration message. This action forces the VLR to send prepaid query messages to the STP, rather than to the prepaid SCP. When the STP receives a query message relating to call originating from the prepaid subscriber, the STP performs a number portability database lookup and determines the routing number corresponding to the called subscriber and the prepaid SCP corresponding to the calling subscriber. The STP then routes the query message to the appropriate prepaid SCP.

    Abstract: 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.

  • Methods, systems, and computer readable media for selectively processing or redirecting signaling connection control part (SCCP) messages
    Patent number: 7916857
    Abstract: The subject matter described herein includes methods, systems, and computer program products for selectively processing or redirecting SCCP messages. According to one method, an SCCP message addressed to an STP and sent route-on-PC-SSN is received at the STP. It is determined whether the SCCP message can be processed locally by the STP. In response to determining that the SCCP message can be processed locally by the STP, the SCCP message is terminated, processed locally, and a response is sent to the message originator. In response to determining that the message cannot be processed locally at the STP, the SCCP message is redirected to a destination.
