In telephony, call control refers to the software within a telephone switch that supplies its central function. Call control decodes addressing information and routes telephone calls from one end point to another. It also creates the features that can be used to adapt standard switch operation to the needs of users. These are called supplementary services and are commonly invoked by a Vertical service code. Examples include "Call Waiting", "Call Forward on Busy" etc.
Networked computer telephony system driven by web-based applications
InactiveUS6922411B1Improve developmentEasy to deploySpecial service for subscribersData switching by path configurationQuality of serviceThe Internet
A networked telephony system and method allow users to deploy on the Internet computer telephony applications associated with designated telephone numbers. The telephony application is easily created by a user in XML (Extensible Markup Language) with predefined telephony XML tags and easily deployed on a website. The telephony XML tags include those for call control and media manipulation. A call to anyone of these designated telephone numbers may originate from anyone of the networked telephone system such as the PSTN (Public Switched Telephone System), a wireless network, or the Internet. The call is received by an application gateway center (AGC) installed on the Internet. Analogous to a web browser, the AGC provides facility for retrieving the associated XML application from its website and processing the call accordingly. The architecture and design of the system allow for reliability, high quality-of-service, easy scalability and the ability to incorporate additional telephony hardware and software and protocols.

A wireless system and method for implementing call controls (such as parental controls) for wireless telephones via a call-intercept platform (including a soft switch and / or an SS7 interconnection node, and SQL database), and a conventional mobile phone that makes and receives all outgoing calls through the call intercept platform. The call intercept platform includes secure web server to provide a secure website point of entry for allowing parents to specify a ruleset of parental controls that is stored in the SQL database. Every outgoing call from the mobile phone is routed into the call-intercept platform, which logs the call, crosschecks the mobile phone and outgoing call number against the stored ruleset for that phone / user, and selectively screens te calls. Incoming calls are automatically forwarded from the wireless carrier to the call intercept platform and are logged, cross-checked and selectively screened. The secure web portal allows parents and guardians or other individuals who desire to self-limit call usage to thoroughly manage their dependent's or their own phone, inclusive of viewing calls, activating and deactivating controls, customizing controls, as well as purchasing prepaid minutes and managing their accounts.

Voice call redirection for enterprise hosted dual mode service
ActiveUS7664495B1Network topologiesCommmunication supplementary servicesDevice registerSpecific function
Systems and methods provide a single E.164 number for voice and data call redirection and telephony services such as caller identification, regardless of in which type of network a dual mode mobile device operates. When the dual mode device registers and is active in a GSM network, temporary routing and status updates are triggered and resultant information is maintained in both networks. A mobile terminated call is routed through an enterprise WLAN with call control within the enterprise being handled by SIP or H.323 signaling, and the call is redirected to the mobile device in the GSM network, where call control is assumed by the SS7 network. Services are provided using the protocols native to the active network, and the single E.164 is used consistently along with or lieu of the temporary routing information for subscriber identity specific functions, such as caller identification and voice mail.

In order to provide a single common cost-efficient architecture for real time communication services for audio, video, and data over internet protocol, a voice over internet protocol (VoIP) system and architecture is provided by placing border elements (BEs) at the interface boundaries between the access network the user devices use and the VoIP infrastructure. The BEs use SIP protocol as the access call control protocol over any access networking technologies, for example, IP, Ethernet, ATM, and FR, and provides all services transparently to the end users that use SIP-enabled devices. To enable a scalable system, the SIP BEs are decomposed into separate communicating entities that make the SIP BE scalable and provide new capabilities not previously available by a self-contained SIP BE. Further, multiple levels of decomposition of a SIP BE can be provided by the present invention supporting a flexible and scalable SIP BE design that further improves system efficiencies and cost advantages as compared to use of single integrated border or edge elements. Further, a scalable SIP BE, made up of a plurality of physical entities for optimization of a large scale design, acts as a single integrated functional entity to logically execute a set of functions at the border of a VoIP infrastructure.

Dynamically switched and static multiple video streams for a multimedia conference
An end station for a videoconference / multimedia conference is disclosed, where the end station requests, receives and displays multiple video streams. Call control messages request video streams with specified video policies. A static policy specifies a constant source video stream, e.g., a participant. A dynamic policy dynamically maps various source streams to a requested stream and shows, for example, the current speaker, or a round robin of participants. A network access device, e.g., a media switch or a video composition system, mediates between the multi-stream end station and the core conference system. Multi-stream endpoints need not handle the complexity of directly receiving video according to a potentially wide variety of call control protocols, formats, and bit-rates. Multi-stream endpoints decentralize compositing video streams, which increases functional flexibility and reduces the need for centralized equipment.

InactiveUS6856612B1Minimize delayMinimize the numberInterconnection arrangementsFrequency-division multiplex detailsThe InternetTranscoding
A method and system for communicating information includes evaluation regarding routing of calls performed at a call control point in an ITSP and / or wireless network. A PIC identity associated with another party's preferences is acquired and sent to the call control point. The PIC identity identifies the type of the carrier network (e.g., circuit switched or VoIP) and is used to make further routing decisions. If a circuit-switched carrier is identified, the IP homing leg is terminated at the voice gateway in the recipient's HPLMN and information is sent over to the GMSC where normal, circuit-switched routing procedures. If a VoIP carrier is identified then the called user's roaming number is retrieved from the HLR, and the call is further routed directly over the IP domain towards a voice gateway at the visited network minimizing the number of transcodings. Additional transcoding steps can be avoided if a single encoding is agreed upon according to “tandem free operation” (TFO). Combining inband signaling through the telephony exchanges and out-of-band signaling in the IP network it is possible to achieve, for a mobile subscriber, one encoding and one decoding of a voice.
