Establishment of a Secure Connection for a Communication Session

A system, method, node, user equipment and computer program for establishment of a secure connection between a user equipment (100) and a media gateway (130) at setup of a communication session with another party (150) is described. The media gateway (130) is controlled by a control server (120). The control server (120) receives a communication session setup request from the user equipment (100) and determines an indication of a security certificate of the media gateway (130). The control server (120) then sends the indication of the security certificate of the media gateway (130) to the user equipment (100), wherein the indication is sent before or in parallel to sending the communication session setup request towards said other party (150). The user equipment (100) then initiates a negotiation of security related parameters, based on the received indication of the security certificate of the media gateway (130). Then the secure connection between the user equipment (100) and the media gateway (130) is established, utilizing the negotiated security related parameters.

TELECOMMUNICATION SYSTEM AND METHOD FOR TRAVERSING AN APPLICATION LAYER GATEWAY FIREWALL DURING THE ESTABLISHMENT OF AN RTC COMMUNICATION CONNECTION BETWEEN AN RTC CLIENT AND AN RTC SERVER
20170237708 · 2017-08-17 ·

The invention relates to a telecommunications assembly (10) and a method for traversing an application layer gateway firewall (40) during the establishment of an RTC communication connection between an RTC client (20) and an RTC server (30) using a proprietary RTC signalling protocol, wherein the firewall (40) has no specific knowledge of the proprietary RTC signalling protocol. The method comprises the following steps: the RTC client (20) and the RTC server (30) negotiate during the establishment of the RTC communication connection which of the ports (P1, P2, P3) of the firewall (40) are required for the data packets to be exchanged via the RTC communication connection, wherein they use at least one standardised message element as a component of the proprietary RTC signalling protocol, with which information relating to the ports to be used can be found; during the establishment of the RTC communication connection the firewall (40) detects, with the aid of the standardised message element, which of the ports (P1, P2, P3) of the firewall (40) are considered by the RTC client (20) and the RTC server (30) to be necessary for the data packets to be exchanged via the RTC communication connection; and the firewall (40) opens and closes the required ports (P1, P2, P3) in a dynamic manner according to the result of the negotiation.

A Mobile Voice Self Service (MVSS) system that may include an MVSS mobile device and a client system. The system may be used to provide passive outdial support for a mobile device via WAP Push of an MVSS URL. The MVSS mobile device may have various local applications such as a bootstrap application and an outdial application. The client system may include an application server to deliver an MVSS file to the MVSS mobile device.

METHOD OF CONTROLLING A REAL-TIME CONFERENCE SESSION

In a method of controlling a real-time conference session there is a first user and a second user connected to a media processing unit. The first user has a passive mode wherein data is received at and transmitted by the first user's communication terminal as passive data but not received by the communication terminal of the second user and an active mode wherein the data is received and transmitted by the first user's terminal and received by the second user's terminal as active data. When the first user switches from the passive mode to the active mode there is a duration of the conference call that is left to be transmitted to the second user. That portion has been recorded and is played at a faster rate to the second user.

Terminal apparatus, content transmission method, and content playback system

A terminal apparatus includes by way of a gateway apparatus that performs communication with an in-vehicle apparatus capable of playing back a content through a CAN bus, a first communication section that transmits command information for changing a mode of the in-vehicle apparatus to the in-vehicle apparatus, and a second communication section that transmits content data to the in-vehicle apparatus.

System and methods thereof for delivery of popular content using a multimedia broadcast multicast service
11240335 · 2022-02-01 · ·

A content caching system intercepts a request from a user device for delivery of an item of popular content stored in the cache, redirects the request to a gateway based on a determination that the requesting device may receive the item from the gateway which provides a multicast service for the item, wherein the redirecting occurs subsequent to the device being able to join a wireless multicast of the requested content after a period of delivery of a portion of the content from the cache to the device while the content is in the midst of being delivered to the device so that delivery from the cache is terminated and delivery continues such that a subsequent portion of the popular content is delivered to the device from the gateway as part of the wireless multicast.

System and method for managing streaming services

A gateway for location at a user premises is provided. Bother users and user devices are registered with the gateway which is provided by a service provider. Users access services, such as video streaming, on their user devices via the gateway. The gateway allows users to share content. The gateway collects information about the user's patterns of behaviour for the system provider, and can be used to directly obtain feedback from the users.

System and method for enabling VPN-less session setup for connecting mobile data devices to an enterprise data network
09763164 · 2017-09-12 · ·

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.

SYSTEM, METHOD, AND APPARATUS FOR IP-BASED RADIO COMMUNICATIONS

System, method, and apparatus for Internet Protocol (IP) based radio communications. One or more browser-based dispatch consoles connect to one or more Radio over IP (RoIP) gateway device over an untrusted network (e.g., the public Internet) using a Web Real-Time Communication (WebRTC) connection secured with SSL/TLS. Each RoIP gateway device provides an analog interface to the radio domain so as to communicate with one or more radio. This architecture avoids any ongoing connection to a centralized cloud-based server and maintains secure radio communications over the untrusted network. Each browser-based dispatch console accesses each RoIP gateway device from a standard web browser thus enabling portability across any platform that supports a browser.

A masking system prevents a human agent from receiving sensitive personal information (SPI) provided by a caller during caller-agent communication. The masking system includes components for detecting the SPI, including automated speech recognition and natural language processing systems. When the caller communicates with the agent, e.g., via a phone call, the masking system processes the incoming caller audio. When the masking system detects SPI in the caller audio stream or when the masking system determines a high likelihood that incoming caller audio will include SPI, the caller audio is masked such that it cannot be heard by the agent. The masking system collects the SPI from the caller audio and sends it to the organization associated with the agent for processing the caller's request or transaction without giving the agent access to caller SPI.
