Abstract:
Method for transmitting the status data of an answering service comprised in a local exchange in a telecommunication system comprising a local exchange (LE), an answering service (1) connected to the local exchange, an access node (AN) connected to the local exchange, a wireless communication system (WLL) connected to the access node and a telecommunication terminal (MS) connected via the wireless communication system to the access node. In the method, a port-specific connection from the access node (AN) to the local exchange (LE) is set up, the status of the answering service (1) is verified in the access node (AN) and, based on the status of the answering service (1), an announcement is sent from the access node (AN) to the telecommunication terminal (MS). The system comprises means (2) for setting up a port-specific connection to the local exchange (LE), means (3) for verifying the status of the answering service (1) and means (4) for sending an announcement to the telecommunication terminal (MS) on the basis of the status of the answering service (1).
Abstract:
A system and method in a radio telecommunications network of storing calling line identification (CLI) information when a called mobile terminal (15) is not available to receive the CLI information, and forwarding the CLI information to the called mobile terminal when the terminal becomes available. When an incoming call for the mobile terminal is received in a gateway mobile switching center (G-MSC) (12), the Home Location Register (HLR) (13) or the visited MSC (V-MSC) (14) where the mobile terminal is operating determines whether the mobile terminal is available. If not, the G-MSC sends a short message service (SMS) point-to-point (PTP) message (28) to a message center (MC) (16) and includes the CLI information. The MC is notified when the mobile terminal becomes available. The MC then forwards the CLI information to the V-MSC in an SMS PTP message (32). The V-MSC sends the CLI information to the mobile terminal in an IS-136 R-DATA message (34) or other appropriate data message.
Abstract:
An intelligent network telecommunications service allows a calling party (22) to provide a voice message which is converted by the service to a text message. The text message is delivered to any of a plurality of types of media formatters (90), which in turn transmit the text message to corresponding types of receiving equipment (100). The text messages can be delivered to a so called party or to a distribution list of called parties.
Abstract:
The invention relates to a method for monitoring an object by means of a decentralized alarm detection unit assigned to said object and an alarm centre, which are connected to each other via a digital data network comprising a signalling channel and a message/data transmission channel. According to said method, when an alarm is detected (1), an information element representing a desired connection is transmitted from the decentralised alarm detection unit to the alarm centre, via the signalling channel of the digital network, with said information element comprising an information element which clearly identifies the decentralized alarm detection unit. The information element which clearly identifies the decentralized alarm detection unit is stored (7) by the alarm centre, after which an alarm signal signalling the alarm detection unit is generated (9). If the message/data channel of the digital data network is free, a connection is established (13) between the alarm centre and the alarm detection unit. In addition, when there are gaps in the signalling, test information elements are transmitted cyclically from the decentralized alarm detection unit to the alarm centre through the signalling channel, the presence and/or absence of test information elements enabling the alarm centre to make deductions regarding the decentralized alarm detection unit.
Abstract:
A method and apparatus for providing a telephone operating company with the ability to rapidly deploy advanced services into a public switched telephone network includes a programmable service node interacting with a programmable switch matrix. The call processing of a call (associated with one or more ports) on the programmable switch matrix is controlled externally when particular triggering criteria is met (i.e., the call requires or desires external control). When the triggering criteria is met, the service node outputs a new call event notification message over a communications link to an external unit and receives one or more messages over the same link. Call control processing is achieved through this high-speed communications link between the programmable switch matrix and the external unit using a communications protocol defining a comprehensive set of primitives (instructions) for call manipulation and control at the programmable switch matrix which are received by the programmable service node. The one or more received messages include instruction data for instructing the programmable switch matrix to perform one or more actions associated with the service call, such as connecting a port with another port within the switch matrix. The service node processes the instruction data and instructs the switch matrix to perform the appropriate action(s).
Abstract:
Incoming calls or messages for a mobile station (30) that has been ported from a first HLR (90A) to a second HLR (90B) are first received by a gateway node (80). The gateway node, in turn, transmits a signal (145) requesting routing instruction to a centralized database (150) connected to the gateway node. Utilizing the received Mobile Station Integrated Services Digital Network (MSISDN) number, the centralized database determines the network address of the new HLR currently serving the ported mobile station. The received signal requesting routing information is then routed to the new HLR. The new HLR retrieves the requested information and transmits it back to the gateway node. The gateway node, utilizing the received routing information received from the new HLR, accordingly routes the incoming calls or messages to the ported mobile station.
