System and method for geographic SIP scaling
A system and method for scaling a session initiation protocol communication system that allows components of the system to be distributed and/or scaled across multiple and different hardware, networks, systems, and locations.
Method and system for a multitenancy telephone network
A method and system for operating a multitenancy telephony system including receiving a plurality of call requests associated with an application server; selecting a subset of the received call requests using a load balancer; assigning each selected call request to one of a plurality of resources creating, on the assigned resource, a call session for each selected call request; and coordinating the created call sessions resulting from the selected subset of the received call requests associated with the application server.
Connection control with B2BUA located behind NAT gateway
There is proposed a mechanism for a connection control conducted in a communication network (such as IMS) when a back to back user agent (B2BUA) and network address translation function are involved in the establishment of the connection. When a control network element, such as a P-CSCF, receives a signaling message related to the establishment of the communication connection, via a communication leg coming from a network address translation device, it is determined whether address information contained in an SDP element of the signaling message matches with preset address information allocated to a border gateway function or BGF. When no matching is determined, normal processing like an initiation of a latching procedure at an own BGF is conducted. Otherwise, if a matching address information is determined, i.e. a mirrored SDP is deemed to be present, a latching processing at an own BGF is inhibited and the received BGF's address information are used in the connection establishment procedure. This processing is conducted at all session ends coming from the B2BUA, so that a communication connection with media flow can be established through pinholes of the BGF(s).
WebRTC API redirection with interception techniques
A computing system includes a server to execute a first portion of a real-time media application so as to integrate with other desktop applications and other operating system functionality, and to redirect intercepted APIs of the real-time media application based on redirection code injected into the real-time media application so that a second portion of the real-time media application is redirected. A client computing device communicates with the server, and executes the redirected second portion of the real-time media application. The redirected second portion of the real-time media application corresponds to real-time media processing and networking off-loaded from the server to the client computing device.
Registration of SIP-based communications in a hosted VoIP network
Aspects of the present disclosure involve systems, methods, computer program products, and the like, for implementing a registrar component or functionality in a telecommunications network. In one implementation, the registrar functionality is handled at a Session Border Controller (SBC) or Network Address Translation (NAT) Traversal Manager (NTM) device of the network to alleviate an application server of the network from performing the registration function.
Method of IMS (SIP network) webRTC optimized P2P communication
A WebRTC system, device and method enabling a P2P communication when both ends of a communication are WebRTC enabled devices. The system and devices also enable a WebRTC client to SIP device communication. A SIP interworking function is configured to receive a SDP1 from an originating WebRTC and obtain local media information from a media interworking function. The first SIP interworking function is configured to create a SDP2 based on the SDP1 and the local media information, create a SIP message comprising a message-body field including the SDP2 and an SIP extension header field including the SDP1, and send the SIP message to an IMS or SIP server.
METHODS AND APPARATUS TO PERFORM NETWORK-BASED MONITORING OF MEDIA ACCESSES
An example apparatus includes: at least one memory; instructions in the apparatus; and processor circuitry to execute the instructions to: determine whether a census impression record corresponds to a panelist impression record by: comparing a first internet protocol (IP) address of the panelist impression record with a second IP address of the census impression record; and comparing a first timestamp of the panelist impression record with a second timestamp of the census impression record; and send a comparison result to a computer of an audience measurement entity, the comparison result indicative of a match confirming the census impression record corresponds to the panelist impression record of the audience measurement entity.
OVER THE TOP NETWORK TRAFFIC CLASSIFICATION
A system and method is disclosed to transform Over-The-Top (OTT) call log data collected by telecommunications network operators into a peer-to-peer log in order to determine more accurate information. In this method the IP addresses in the call log records are compared to a list of known mediator server IP addresses and the records in the log that contain mediator server IP addresses are removed from the log to create a peer-to-peer log containing only those records that contain peer IP addresses. The data in the peer-to-peer log can then be categorized with confidence to determine network performance information as well as, for example, the percentage of traffic to a particular country. Conclusions may then be inferred regarding the removed data records based upon the data found in the peer-to-peer log.
Region-based redirection and bridging of calls
Apparatus and methods are disclosed for bridging communications between a private network and a public network. A mapping that associates a first set of IP addresses of endpoints in the private network with a second set of IP addresses of endpoints in the public network is provided which enables communications between the private network and public network for network-address-translation (NAT). In response to a data packet having a first IP address of the first set of IP addresses, the data packet is used to determine whether the local line should be accessed. In response to an indication that the local line should be accessed, the identifier among the second set of IP addresses may be used to activate bridging (e.g., ATB) circuit and redirect a call associated with the data packet by passing the data packet through the ATB circuit.
Methods and apparatus for managing the use of IP addresses
The present invention relates to communications methods, apparatus and systems for efficiently managing NAPT bindings and mappings. An exemplary embodiment of operating a communication system includes the steps of (i) receiving, at a real-time communications entity, a media session offer from a device, (ii) transmitting, from the communications entity to a Network Address and Port Translation entity (NAPT), a request signal to allocate a public Internet Protocol (IP) address and port number pair corresponding to an interface on the NAPT for the session; (iii) determining, at the communications entity, a remote IP address and port number pair corresponding to an interface on the device to be used for communicating media of the media session; (iv) transmitting, from the communications entity to the NAPT, a signal identifying the determined remote IP address and port number pair; and (v) releasing, at the NAPT, the allocated public IP address and port number pair.
