In one embodiment, a network interface receives a communication request. A processor then verifies caller information in the communication request with a certification procedure. The processor obtains a first indicator based on the certification procedure. The first indicator includes information associated with a first certificate management procedure. The processor generates a second indicator based on the first indicator. The second indicator includes information associated with a second certificate management procedure.

A user authentication system that analyzes call forwarding information obtained from telecommunication networks, such as through the use of Signaling System No. 7 (SS7) protocols, to detect the possibility of fraud. In response to a request to access a network-accessible service, the system performs an initial authentication of provided user account credentials. The system then obtains a telecommunication subscriber identifier that is associated with the user account. Prior to performing additional device-based user authentication, the system obtains call forwarding information for the user. The obtained call forwarding information is then evaluated for potentially fraudulent call forwarding configurations. For example, call forwarding to certain call forwarding numbers, or the use of different call forwarding types, may be indicative of fraud intended to undermine further user authentication.

A method is provided for securing a Signalling System No. 7 interface, SS7 interface, of a system, via which access to a local mobile radiocommunications network is carried out, in relation to an external system. The method protects the SS7 network access points of telecommunication providers from SS7/MAP attacks by detecting and filtering these attacks.

Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.

An IP short message gateway (IP-SM-GW) utilizes multiple addresses for delivering short messages between an IP network and a cellular network. The IP short message gateway can have multiple SCCP addresses that correspond to categories of origin/destination IP addresses of short messages. In response to a request to deliver a short message between an IP network and a cellular network, the IP short message gateway identifies an IP address associated with the origin/destination of the short message. The IP short message gateway then identifies at least one of its multiple SCCP addresses based on the identified IP address. The IP short message gateway can generate a response message that includes the identified SCCP address. The identified SCCP address in the response message will be available to SMSC or IMS. SMSC or IMS can implement differentiated handling of short messages based on SCCP addresses received from the IP short message gateway.

A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.

A mobile application gateway for connecting devices on a cellular network with individual networks, such as enterprise voice and data networks and/or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise. The invention may consist of a primarily of core network and services components based on the IMS network architecture, and is backward compatible to support legacy systems in place in current telecom and data networks.

A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

Methods and systems for configuring communication at a premises are described. A network device at a premises may be in communication with a first network and a second network. The network device may receive data from a security system and a communication device located at the premises. The network device may transmit the data via the first network or the second network based on configuration data, which may be received from a remote server located external to the premise.
