Patent number: 9450781Abstract: Systems and methods are disclosed for reporting spam detected in a communication network. Entities in the network detect that an electronic message comprises spam, and generate a spam report for the electronic message. The spam report is in a format that is enhanced with newly-defined fields. A spam center in the network receives the spam reports from the entities, and processes the spam reports to generate spam rules for detecting spam in electronic messages transported over the communication network. The spam center then selectively distributes the spam rules to one or more of the entities of the communication network based on an analysis of the spam reports. The entities may then use the spam rules to detect spam in other electronic messages that are transported over the communication network.Type: GrantFiled: December 9, 2010Date of Patent: September 20, 2016Assignee: Alcatel LucentInventors: Yigang Cai, Gyan Shanker

Patent number: 9439057Abstract: An LTE subscriber database pushes a registration notification to a SMSC or IP-SM-GW when subscriber registers/deregisters to LTE. The subscriber registration information is stored in local database. Thus, MT SMS may be delivered to a registered subscriber without querying the subscriber database each time for registration information. An exemplary apparatus includes an interface for receiving a registration status message for a mobile device over a broadband network, a subscriber database, and a control system for storing subscriber information in response to receipt of the registration status message and forwarding a notification of subscriber registration status including subscriber registration information to a first network device when the mobile device registers or deregisters to the broadband data network.Type: GrantFiled: September 30, 2009Date of Patent: September 6, 2016Assignee: Alcatel LucentInventors: Jay B.

Patent number: 8848604Abstract: Systems and methods are disclosed for correlating messages used to deliver an Application Originated (AO) text message to User Equipment (UE). A text message gateway is implemented between a text message application and a packet-switched network that uses Session Initiation Protocol (SIP). The text message gateway receives a delivery request from the text message application that includes an Application Originated (AO) text message intended for the UE. The text message gateway identifies a correlation identifier (ID) for the AO text message, inserts the correlation ID in a delivery response, and transmits the delivery response to the text message application (to store for later use). The text message gateway also converts the delivery request into a SIP request that encapsulates the AO text message, inserts the correlation ID in the SIP request, and transmits the SIP request to the UE.Type: GrantFiled: January 10, 2011Date of Patent: September 30, 2014Assignee: Alcatel LucentInventors: Yigang Cai, Gyan Shanker

Patent number: 8271007Abstract: Systems and methods are disclosed for managing Short Messaging Service (SMS) spoofing using Short Messaging Peer-to-Peer (SMPP) protocol. An SMPP protocol communication includes an SMPP transmitter and an SMPP transceiver. The SMPP transmitter identifies or receives an SMS message for transmission to a destination. The SMPP transmitter identifies a source address for the SMS message, and determines whether the source address is authentic. If the source address is not authentic, then the SMPP transmitter inserts a validity indicator in an SMPP Packet Data Unit (PDU), along with the SMS message, that the source address is not authentic before transmitting the SMPP PDU to the SMPP transceiver. Upon receiving the SMPP PDU from the SMPP transmitter, the SMPP transceiver may determine whether or not to deliver the SMS message to the destination based on the validity indicator provided by the SMPP transmitter.Type: GrantFiled: January 6, 2010Date of Patent: September 18, 2012Assignee: Alcatel LucentInventors: Yigang Cai, Gyan Shanker
