Abstract:
A service that leverages established wireless messaging paradigms such as, possibly inter alia, Short Message Service, Multimedia Message Service, and IP Multimedia Subsystem to yield an infrastructure that (1) supports a comprehensive Common Short Code directory that seamlessly spans or crosses the disparate 'islands' of national/regional Short Code information and that offers, possibly among other things, a full-featured search capability and (2) allows a Mobile Subscriber to seamlessly employ their Wireless Device to interact with same. The service may optionally leverage the capabilities of a centrally-located Value-Added Service Provider.
Abstract:
A method for resolving a network address of a terminal, said terminal being assigned a SIP address, the method comprising: receiving an address resolving request relating to the terminal in a routing unit of a telecommunication network, the address resolving request being associated to the SIP address; forwarding the address resolving request to a resolving unit; sending address queries to address servers and/or databases from the resolving unit; receiving, from each of the address servers and/or databases, the network address of the terminal or an error message indicating the network address of the terminal was not found; and sending a response to the address resolving request to the routing unit of the telecommunication network, the response including either the network address of the terminal or the error message.
Abstract:
The present invention relates to a method and network elements for providing portability of at least one of a name and a number of a subscriber between a first network and a second network. A first network element is configured to re-spond to a location information request, which comprises at least one of the name and the number of the subscriber in the first network, with an answer indicating an address of an entry point network element of the second network, and a second network element is configured to respond to a location information request, which comprises the at least one of the name and the number of the subscriber in the first network, with an answer indicating an address of a serving network element of the second network. Thereby, a distributed architecture for portability can be implemented in a simple manner involving minimum network changes.
Abstract:
According to one embodiment of the invention, a system is provided that comprises a communication point database configured to provide a communication point data set; a party database configured to provide a party data set; wherein the communication point database and the party database are communicatively coupled with one another so as to associate the communication point data set with the party data set; a relationship type code database communicatively coupled with the communication point data set and the party data set.
Abstract:
An apparatus and method for number portability for an IMS network. In one example the method may have the steps of: processing all calls with E.164 numbers in a BGCF (Breakout Gateway Control Function); executing digit analysis on a respective E.164 number in the BGCF; and querying, by the BGCF, a NPDB (portable number database) to retrieve a routing number if the respective E.164 number is ported.
Abstract:
A telephone number of the callee is received from a caller device. An Internet protocol Multimedia Subsystem (IMS)-based telephone number mapping (ENUM) query is constructed based on the telephone number of the callee. An ENUM database is queried based on the ENUM query. If a response to the ENUM query is absent a Session Initiation Protocol (SIP) Uniform Resource Indicator (URI) or a telephone (TEL) URI, the telephone number is resolved into one or more non-SIP/non-TEL URIs usable to communicate with the callee. The caller is enabled to use the caller device or other devices to select which of the one or more non-SIP/non-TEL URIs to use to communicate with the callee. For each caller-selected non-SIP/non-TEL URI, communication in a protocol associated with the URI is initiated between the caller and the callee using the caller device or other devices.
Abstract:
The present disclosure generally relates to systems and methods for establishing and maintaining communication between two or more communication devices (10, 60) coupled to communication networks (31). Some specific aspects relate to communication between a plurality of communication devices (10, 60) each of which is coupled to a respective network (31). Other aspects relate to establishing such communication by way of contact lists maintained and facilitated on systems coupled to the networks (31). Users of multiple communication networks (31), such as VoIP, PSTN and wireless, employ multiple communication devices to communicate with their contacts. For example, a VoIP enabled computer is necessary to access contacts on a VoIP network (31) and a mobile or cellular telephone (60) is used to access contacts on wireless and PSTN networks (51). A contact list, stored on one communication device (10, 60), in some instances, cannot be accessed from another communication device (10, 60). For example, a contact list stored in a VoIP enabled computer cannot be accessed from PSTN or wireless phone devices (60).
Abstract:
At least one device receives a call request from a calling party to a called party. The device routes the call request to an Internet Protocol Multimedia Subsystem (IMS) core when a first condition is met and bypasses the IMS core when a second condition is met.
Abstract:
Bei der Einführungsphase von ENUM ergibt sich ein Problem, wenn für den angerufenen Teilnehmer kein ENUM-Eintrag vorliegt. Der anrufende Teilnehmer kann in dieser Situation zwar eine ENUM-Anfrage starten, erhält aber nur eine Fehlermeidung, da zu diesem FQDN kein ENUM-Eintrag existiert. Die Aufgabe der Erfindung besteht darin, die genannte Einführungsphase zu verkürzen. Erfindungsgemäß wird ein gemäß der ENUM-Anfrage angerufener Teilnehmer daher bei Fehlen eines DNS-Eintrags über die Möglichkeiten von ENUM benachrichtigt.
Abstract:
A temporary ENUM architecture assigns a temporary ENUM at call time. For an originated communication requiring routing to a party which needs a particular callback format not supported, the TempENUM provides consistency with the specific format required by the receiving party. The TempENUM is assigned for the duration of the call or communication, or for a given amount of time thereafter. The TempENUM service gateway includes a TempENUM database, a module that assigns a suitable TempENUM at the time of call routing, and a module that handles a lookup in the TempENUM database, and maps the assigned TempENUM to a calling party identifier (CgPID). The TempENUM database stores a TempENUM from a coordinator system and relates the actual calling party identifier (CgPID) for use in callback attempts. Either during the initial call or communication, or shortly thereafter, the receiving party uses the TempENUM number to return communication the initial caller.
