Abstract: A gateway receives a message from a first terminal to establish a connection between the first terminal and a second terminal. The gateway sends a second message to the second terminal to offer a connection. After receiving the first message from the first terminal, the gateway receives subsequent third messages from the first terminal that identify candidates for assisting in the formation of the connection. The gateway saves information about these candidates. The gateway either uses such information for facilitating the formation of the connection or forwards that information to the second communication terminal after receiving an answer accepting the establishment of a connection from the second terminal and determining whether the second terminal has a WebRTC client.

Abstract: A display of an icon includes creating and displaying an icon that provides indicia regarding information relevant to an application to which the icon is assigned. The indicia provides information to a user and is always in the foreground of a display when the application is running regardless of whether the application is currently actively in use and being interacted with by a user or not. At least one expandable indicia is included within the icon. Input provided by clicking the expandable indicia actuates an expanded window for displaying more detailed information. Indicia is also presentable on the icon to provide real time information to a user who is actively using another application such as whether a connection to a server hosting services for the application is lost. A presence state of the user is displayable via presence indicia located on the icon as well.

Abstract: A location information (li) which is available in a mobile terminal device (ME-T) and which indicates the geographical location of the terminal device (ME-T) is embedded in messages (m) of a SIP protocol (SIP) which are exchanged between the terminal device (ME-T) and the network (WLAN) during the establishment of a session and/or during a session and/or during the registration of a terminal device (ME-T) in the network (WLAN), e.g. LAN or UMTS, or during request of a service or a function. By advantageously complementing the SIP protocol (session initiation protocol), the location information can be transmitted from a mobile terminal device (ME-T), which optionally has a telephone function, to the network (WLAN) in any signaling state, thereby substantially reducing the economic outlay for implementing the transmission of location information (li) to the network (WLAN).

Abstract: A method and an apparatus for tracking changes in a collection of web documents, for example, provided by a web site. The web documents are retrieved at a first assigned point in time and a second assigned point in time. Then a similarity measure for a combination of a retrieved web document at a first assigned point in time and a retrieved web document at a second assigned point in time is calculated for determining pairs of corresponding web documents. By comparing said calculated similarity measure of a pair of corresponding web documents with predetermined thresholds for the similarity measure a change in the content of the corresponding web document between the first assigned point in time and second assigned point in time is detected. Instead of referring to identifiers like URLs for web pages the content similarities of web pages are considered. The proposed strategy facilitates the work of marketing analysts.

Abstract: The invention relates to a method for configuring electronic devices, particularly terminals, wherein during configuration at least parts of first configuration data on a chip card are fed to an electronic device, wherein the configuration data are stored on the chip card as second configuration data such that the stored data are the result of an obfuscation following at least one first algorithm. Furthermore, at least parts of the first algorithm can be derived by the electronic device. The stored second configuration data are subjected to a de-obfuscation by the device such that, having knowledge of the first algorithm, they can be reconstructed as first configuration data and the configuration of the terminal can be based thereon. The invention further relates to an arrangement having means for carrying out the method.

Abstract: Embodiments provide methods for modification of an encoded data stream of data packets, wherein each data packet comprises one information bit. In the data stream, the information bits of sequential data packets display time intervals from each other which differ from desired time intervals and which are adapted to the desired time intervals by insertion of an artificially encoded, first data packet into the encoded data stream in the encoded domain temporally after a second data packet, or by removal of a fourth data packet present in the encoded data stream from the encoded data stream in the encoded domain.

Abstract: Multiple-nodes (multiple media servers) can be deployed in a single outbound calling system. Agent nailups can be established with the media servers, on a one-to-one basis (an agent is nailed up to only one of the media servers at any given time). Predictive dialing can be performed by each of the media servers (dialing nodes), resulting in active (answered) calls with customers. If the active call is in a different node than a nailup for an available agent, the controller can direct the agent nailup to be moved to the node which is handling the active call (or call leg).

Abstract: A communication apparatus includes a computer supported telecommunications application (“CSTA”) session established between a computing function and switching function that includes a time period where monitors and registrations are preserved by the switching function if the computing function is able to restart the session within that time period after a temporary connection failure. The switching function tracks call and non-call related device activity that occurs from the time a session failure is detected until the computing function is able to restart the application session in a first list. If the computing function restarts that application within the time period, the switching function sends the computing function a list of devices whose activity was detected during the outage. The computing function uses the list of devices to query the status of those devices to reduce the amount of time needed to perform a recovery and less system performance impacts.

Abstract: A method for the user-based processing of electronic messages comprising file attachments is provided. According to the method, a file attachment of an electronic message is replaced by a memory location link to a selected memory location in a user file system and the file attachment of the electronic message is saved in the selected memory location of the user file system. This permits the memory capacity that is required for storing data attachments to be significantly reduced in a user-friendly system.
