The present invention pertains to a method and system for preventing unauthorized access via signal interception and hacking to a user's secure mobile device. One embodiment of the system further comprises an encryption server in communication with the secure mobile device, a clear server in communication with a clear mobile device, and a termination gateway in connection with secure and clear POTS phones on the PSTN. The termination gateway communicates with the clear and encryption servers by IP tunneling. The system enables universal access between secure and non-secure packet-switched phone lines, operating via the Internet, and clear and secure circuit-switched phone lines operating on the PSTN.

The method performed by a gateway between a LAN and a WAN that includes a platform of the VoIP telephone service, is characterized in that it includes a step of activating the VoIP telephone service on detecting a connected state of a terminal connected to the gateway.

The present invention is directed to communications methods and apparatus for efficiently distributing traffic to processing entities. An exemplary method includes the steps of: receiving, at a first Session Initiation Protocol (SIP) load balancer (SLB), a first SIP INVITE message; selecting, at the first SLB, which Session Border Controller (SBC) in a first cluster of SBCs to send the first SIP invite message based on a message allocation weight determined based on message loss information corresponding to different SBCs in the first cluster of SBCs, the selecting including allocating a portion of incoming received SIP INVITE messages to an individual SBC based on a message loss rate corresponding to the individual SBC and the message allocation rate, said selecting including selecting a first SBC from the first cluster of SBCs to send said first SIP INVITE message, and sending the first SIP INVITE message to the first SBC.

A method for automatic transmission of status information from a first communications terminal set up for speech communication to a second communications terminal set up for text communication is provided. The speech communication between communications terminals is processed over a speech communications server and the text communication between communications terminals over a text communications server. The speech communications server and the text communications server exchange messages over at least one converter device. The status information will be transmitted from the first communications terminal over the speech communications server, the converter device, and the text communications server to the second communications terminal.

This invention is a system and method for implementing a VoLTE and circuit switched voice and SMS interworking function to provide voice and SMS service to roaming mobile devices at visiting network based on VoLTE roaming and ‘SMS over SGs’ towards VPLMN, and circuit-switched voice and SMS towards HPLMN. The interworking function enables and redirects IMS traffic at VPLMN towards a hosted IMS core with voice connectivity to PSTN via MGCF and MGW. The interworking function also performs circuit-switched location-update registration at HLR at HPLMN for receiving mobile-terminated voice calls and SMS.

A gateway device that connects a PSTN network to an IP network includes a signal conversion unit that extracts information necessary for ISUP service provision from information included in a received ISUP signal, and generates an SIP signal in which the information is set in the header, a determination unit that determines whether to relay the header for a connection destination device on the basis of a type of a connection destination device and terminal conditions of an outgoing terminal and an incoming terminal that are set in the ISUP signal, and a relay unit that relays the SIP signal to a connection destination device in a case of relaying the header, and transmits an SIP signal from which the header has been deleted to a connection destination device in a case of not relaying the header.

A method of switching from a first gateway within a plurality of first gateways to a second gateway in a network includes precaching configuration information on the second gateway, that is within the first gateways, prior to switch-over to the second gateway. The first gateway from which the second gateway is being switched is identified. The second gateway is configured in accordance with the configuration of the first gateway based on the precached configuration information prior to the switch-over to the second gateway. Data traffic from data applications using the network is replicated and sent to the first gateway and the second gateway. Bandwidths allocated to terminals in the network are frozen in association with the switch-over to the second gateway. The bandwidths allocated to the terminals in the network are unfrozen based at least in part on an indication of completion of the switch-over to the second gateway.

A device includes a processor and a memory. The processor effectuates operations including receiving a service capability for a mobile originating (MO) device. The processor further effectuates operations including receiving a service capability for a mobile terminating (MT) device. The processor further effectuates operations including receiving session initiation protocol (SIP) messages from the MO device at a Breakout Gateway Control Function (BGCF). The processor further effectuates operations including determining whether the received SIP messages are associated with setting up an outgoing open group chat (OGC) or an outgoing Message Session Relay Protocol (MSRP) file transfer. The processor further effectuates operations including blocking the SIP messages in response to the determination that the SIP messages are associated with setting up a MSRP file transfer.

Systems and methods for establishing a communication interface between control functions of a network core and a network data node associated with a user side packet core are discussed herein. The system can enable configuration information to be stored and dynamically updated by the network data node such that control nodes of the user side packet core requesting service from the network core are provided with up to date configuration information associated with active control functions. As control functions are activated and deactivated, the configuration information can be updated to reflect the current state of the network core and ensure that user device connects are routed to active control functions configured to provide user requested services.

Disclosed herein are a method for broadcast gateway signaling using a cloud network and an apparatus for the same. The method includes generating an outer packet corresponding to the outer layer of a tunneling system using an inner packet corresponding to the inner layer of the tunneling system, generating a header of the outer packet, and transmitting the outer packet to a transmitter through a Studio-to-Transmitter Link (STL). The header includes an STL propagation delay time field indicating a reception wait time for an STL stream corresponding to the outer packet.
