Abstract: The present invention enables a method for following the state of a call and generating defects as function of call completion success as opposed to discrete events that happen at individual network elements during the call.

CDR is data associated with a telephone call, including the calling and the called numbers, the date and timestamp, the duration, the call setup delay, and the final handling code of the telephone call.

Abstract: The invention provides a system and a method display incoming and outgoing call log data associated with telephone calls to and from a plurality of subscriber telephone numbers from one or more telephone networks. The system includes a switch in one network that receives a telephone call from the subscriber's telephone and launches a query in response to an AIN trigger to a service control point. In response, the service control point forwards associated call data to a call log gateway that translates the message into an asynchronous message containing call log data. The call log gateway forwards the asynchronous message to a unified communication platform where it is placed in subscriber mailbox and made available as a call log to a subscriber via a graphic user interface over the internet. A web server retrieves the call log and displays it to the subscriber at a web client.

Abstract: A system for billing Internet protocol (IP) telephony, or other telecommunication calls transmitted over data packet networks, is provided. Calls may be routed over networks of different types, e.g., H.323 networks or IP voice networks. Different types of network devices, e.g., call managers, switches, or gateways, may transmit legs within a call. Each device type typically generates call records that have data fields unique to that device. In order to generate a single billing record for each call, call records are standardized and then matched with call records from other devices. Key fields within call records that may be matched include: call connect timestamps, signal start timestamps, calling party identifiers, called party identifiers, or network device identifiers. Timestamps within call records may be synchronized from a common time server.

In addition to identifying fraudulent and misbilled calls, the called party's name allows a person reviewing the billing record to quickly identify long distance calls, quickly discern business from personal calls, and audit calls made from phone lines with multiple users (e.g., employees or kids). Additionally, the billing record reviewer saves time and money by avoiding the need to call directory assistance or a billing service to identify the calls.

Abstract: A mobile switching center is configured with software instructions which allow it to continue to provide at least limited call termination and call origination services for mobile terminals in the event of a failure of a signaling link between the mobile switching center and a home location register and/or a signal control point (SCP) in an intelligent network. For pre-paid callers originating or terminating a call, the mobile switching center marks a call detail record as indicating that the call is a post-paid call. The call detail record is later provided to the SCP after the signaling link has been restored in order to bill the mobile terminal. In one example, the signaling link between the mobile switching center and the home location register or SCP may be a satellite link, which may go down for various reasons such as for maintenances, an unexpected failure, or the orbit of the satellite goes outside the field of reception of an antenna in the signal path.

Abstract: In a signalling network employing the SS7 signalling protocol, it is known to use masks to mine CDR stores in order to obtain data for analysis in respect of a particular customer of a communications network associated with the signalling network. However, the use of masks to mine the CDRs can result in the retrieval of unwanted CDRs or the omission of relevant CDRs. The present invention therefore provides a call monitoring apparatus that receives a CDR and accesses a reference database, comprising a list of customers and respective telephone numbers, in order to identify an association between the CDR and a given customer. Consequently, speed and efficiency of analysis of CDRs is increased.

The method includes receiving the plurality of CDRs at a first controller, wherein each of the CDRs include a data structure including a plurality of fields each containing at least one character. The method then selects a first sorting field from the plurality of fields and groups the plurality of CDRs as a function of data within the first sorting field. In one embodiment, the first sorting field is used to group the CDRs according to different carriers. The method then analyzes at least one additional sorting field within each of the CDRs which were previously grouped according to the first sorting field. A report is then generated for each of the grouped CDRs as a function of data within the additional sorting field. In this way, periodic, customized reports can be generated from information contained with CDRs with user-selectable sorting or analysis fields.

Abstract: Techniques and systems for routing and information collection for telephone calls are described. Upon initiation of a revenue generating call, a data management module creates a call interaction record, including a unique call identifier and information generated by an exchange originating the call. Call accounting information such as user identification and billing account information are collected from the user by presenting audible queries from the user and receiving voice responses. The voice responses are matched to stored information, which is stored in the call interaction record. If a voice response does not unambiguously identify the requested information, further queries may be presented to elicit more refined responses or request responses for recording and later playback. Routing information is then collected, again through audible queries and voice responses, and stored. Upon completion of the call, the call interaction record is closed and stored for later retrieval and analysis.

The billing server responds to the request message with billing request data. Advantageously, this arrangement minimizes the problems of updating a large number of subscriber identification/billing server identification databases.

Abstract: Passengers on board a vehicle make and receive calls via a satellite network. That network sees each passenger involved in a call as a temporary dummy subscriber of the satellite network. Thus the satellite network is used to manage the roaming of passengers on aircraft. An intermediate network and the terrestrial mobile telephone network therefore do not need to manage the roaming of the aircraft. The terrestrial mobile telephone network sees each node of the intermediate network as a dummy base station and each passenger involved in a call as a dummy mobile subscriber of the terrestrial mobile telephone network, in the service area of one of the dummy base stations. The terrestrial fixed telephone network sees each passenger involved in a call as a subscriber of another fixed network managed by another operator. The intermediate network sees the satellite network as a standard terrestrial mobile telephone network, able to manage the roaming of its subscribers itself.

The media proxy server copies the media stream to a delivery function. If the surveillance type is non-content-related, the surveillance and signaling router sends a copy of the message or information extracted from the message to an external device.

Each of the plurality of transaction records are also analyzed to determine whether each transaction record is within a desired category of transaction records. When any one of the plurality of transaction records within a file is not within the desired category of transaction records, a second flag is set to indicate an erroneous transaction record within the file.
