Call Data Record
A call detail record (CDR) is a data record produced by a telephone exchange or other telecommunications equipment that documents the details of a telephone call or other telecommunications transactions (e.g., text message) that passes through that facility or device. The record contains various attributes of the call, such as time, duration, completion status, source number, and destination number. It is the automated equivalent of the paper toll tickets that were written and timed by operators for long-distance calls in a manual telephone exchange. CDR contents A call detail record contains data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call. In actual modern practice, call detail records are m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Telephone Call
A telephone call is a connection over a telephone network A telephone network is a telecommunications network that connects telephones, which allows telephone calls between two or more parties, as well as newer features such as fax and internet. The idea was revolutionized in the 1920s, as more and more ... between the called party and the calling party. First telephone call The first telephone call was made on March 10, 1876, by Alexander Graham Bell. Bell demonstrated his ability to "talk with electricity" by transmitting a call to his assistant, Thomas Watson. The first words transmitted were "Mr Watson, come here. I want to see you." This event has been called Bell's "greatest success", as it demonstrated the first successful use of the telephone. Although it was his greatest success, he refused to have a telephone in his own home because it was something he invented by mistake and saw it as a distraction from his main studies.

Internet Protocol Detail Record
In telecommunications, an IP Detail Record (IPDR) provides information about Internet Protocol (IP)-based service usage and other activities that can be used by operations support systems (OSSes) and business support systems (BSSes). The content of the IPDR is determined by the service provider, network/service element vendor, or any other community of users with authority for specifying the particulars of IP-based services in a given context. The IPDR specifications were originally produced by the Internet Protocol Detail Record Organization, Inc. (aka IPDR.org). In 2007, the IPDR.org organization was acquired by the TM Forum, an industry association of more than 900 global members in over 160 countries from across the converging industries of telecom, cable, media and the Internet. The IPDR specifications include requirements for IPDR collection, encoding and transport protocols to exchange IPDR records, the IPDR service specification design guidance, and several sample IPDR Service ...

Pen Register
A pen register, or dialed number recorder (DNR), is an electronic device that records all numbers called from a particular telephone line. The term has come to include any device or program that performs similar functions to an original pen register, including programs monitoring Internet communications. The United States statutes governing pen registers are codified unde18 U.S.C., Chapter 206 Definitions The term ''pen register'' originally referred to a device for recording telegraph signals on a strip of paper. Samuel F. B. Morse's 1840 telegraph patent described such a register as consisting of a lever holding an armature on one end, opposite an electromagnet, with a fountain pen, pencil or other marking instrument on the other end, and a clockwork mechanism to advance a paper recording tape under the marker. The term ''telegraph register'' came to be a generic term for such a recording device in the later 19th century. Where the record was made in ink with a pen, the term ...

Telecommunications Data Retention
Data retention defines the policies of persistent data and records management for meeting legal and business data archival requirements. Although sometimes interchangeable, it is not to be confused with the Data Protection Act 1998. The different data retention policies weigh legal and privacy concerns against economics and need-to-know concerns to determine the retention time, archival rules, data formats, and the permissible means of storage, access, and encryption. In the field of telecommunications, data retention generally refers to the storage of call detail records (CDRs) of telephony and internet traffic and transaction data ( IPDRs) by governments and commercial organisations. In the case of government data retention, the data that is stored is usually of telephone calls made and received, emails sent and received, and websites visited. Location data is also collected. The primary objective in government data retention is traffic analysis and mass surveillance. By analy ...

NSA Call Database
MAINWAY is a database maintained by the United States' National Security Agency (NSA) containing metadata for hundreds of billions of telephone calls made through the largest telephone carriers in the United States, including AT&T, Verizon, and T-Mobile. The existence of this database and the NSA program that compiled it was unknown to the general public until ''USA Today'' broke the story on May 10, 2006. It is estimated that the database contains over 1.9 trillion call-detail records. The records include detailed call information (caller, receiver, date/time of call, length of call, etc.) for use in traffic analysis "And, by the way, I hate the term 'metadata.' What's wrong with 'traffic analysis,' which is what we've always called that sort of thing?" and social network analysis, "The data are used for 'social network analysis,' the official said, meaning to study how terrorist networks contact each other and how they are tied together." but do not include audio information ...

Customer Proprietary Network Information
Customer proprietary network information (CPNI) is the data collected by telecommunications companies about a consumer's telephone calls. It includes the time, date, duration and destination number of each call, the type of network a consumer subscribes to, and any other information that appears on the consumer's telephone bill. Telemarketers or customer service agents working on behalf of telephone companies must go through an additional customer authentication layer (typically a PIN, or last four of the stored payment method) and ask for the customer's consent prior to accessing the billing information or before using or sharing that information for any purpose, including but not limited to, offering an up-sell or any change of services. Usually, this is done at the beginning of a call from the telemarketer to the telephone subscriber. Description The U.S. Telecommunications Act of 1996 granted the Federal Communications Commission (FCC) authority to regulate how customer propr ...

IMEI
The International Mobile Equipment Identity (IMEI) is a numeric identifier, usually unique, for 3GPP and iDEN mobile phones, as well as some satellite phones. It is usually found printed inside the battery compartment of the phone but can also be displayed on-screen on most phones by entering *#06# MMI Supplementary Service code on the dialpad, or alongside other system information in the settings menu on smartphone operating systems. GSM networks use the IMEI number to identify valid devices, and can stop a stolen phone from accessing the network. For example, if a mobile phone is stolen, the owner can have their network provider use the IMEI number to blacklist the phone. This renders the phone useless on that network and sometimes other networks, even if the thief changes the phone's subscriber identity module (SIM). Devices without a SIM card slot or eSIM capability usually don't have an IMEI code. However, the IMEI only identifies the device and has no particular relatio ...

International Mobile Subscriber Identity
The international mobile subscriber identity (IMSI) is a number that uniquely identifies every user of a cellular network. It is stored as a field and is sent by the mobile device to the network. It is also used for acquiring other details of the mobile in the home location register (HLR) or as locally copied in the visitor location register. To prevent eavesdroppers from identifying and tracking the subscriber on the radio interface, the IMSI is sent as rarely as possible and a randomly-generated TMSI is sent instead. The IMSI is used in ''any'' mobile network that interconnects with other networks. For GSM, UMTS and LTE networks, this number was provisioned in the SIM card and for cdmaOne and CDMA2000 networks, in the phone directly or in the R-UIM card (the CDMA equivalent of the SIM card). Both cards have been superseded by the UICC. An IMSI is usually presented as a 15-digit number but can be shorter. For example, MTN South Africa's old IMSIs that are still in use in t ...

United States Foreign Intelligence Surveillance Court
The United States Foreign Intelligence Surveillance Court (FISC), also called the FISA Court, is a U.S. federal court established under the Foreign Intelligence Surveillance Act of 1978 (FISA) to oversee requests for surveillance warrants against foreign spies inside the United States by federal law enforcement and intelligence agencies. FISA was created by the U.S. Congress based on the recommendations of the Senate's Church Committee, which was convened in 1975 to investigate illicit activities and civil rights abuses by the federal intelligence community. Pursuant to the law, the FISC reviews requests to conduct physical and electronic surveillance within the U.S. concerning "foreign intelligence information" between "foreign powers" and "agents of foreign powers" suspected of espionage or terrorism; such requests are made most often by the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI). From its opening in 1978 until 2009, the court was h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
