Problems solved by technology

[0007] 1. The agent has no control over the type of information stored, i.e., retains all information required by the standard
[0008] 2. The current standard only anticipates simple provisioning methods (query and delivery processes) when agents need stored data, while keeping information delivered as soon as it becomes available may be effective for their lawful interception purposes

Embodiment Construction

[0027] figure 1 A Public Land Mobile Network PLMN is disclosed. In this example, PLMN includes Telecommunication Service Provider TSP, such as MSP: Mobile Service Provider, ISP: Internet Service Provider, MMC: Multimedia Messaging Center, USP: User and Service Profile Database, HSS: Home Subscriber Server, HLR: Home Location Register, IMS: IP Multimedia System, SGSN: Serving GPRS Support Node, ITO: IT Operator Database, MSC: Mobile Services Switching Center, SCP: Service Control Point, SDP: Service Data Point. The aforementioned nodes are all known and specified in various telecommunication standards. A telecommunications service provider TSP generally acquires and stores various user information and business data related to its service provider during its business operation. This information and data may relate to service accounts, payment, access, assigned identifiers and usage. The manner in which this information and data is obtained and stored is determined by a combin...

Abstract

The present invention relates to methods in a telecommunication system to provide access to data received to a centralized storage medium (DR-C) from interfacing traffic nodes in the system. The centralized storage medium is part of a Mediation and Delivery Function (MDF) which is associated with a Law Enforcement Monitoring facility (LEMF). The method comprises the following steps: identifying in the Mediation and Delivery Function (MDF), a configuration request which comprises a filtering criteria specifying type of data to be accessed, configuring in the Mediation and Delivery Function (MDF), the requested filtering criteria, receiving data (Dl) from the system to the centralized storage medium, establishing that the received data matches the filtering criteria, retaining the received data in the centralized storage medium and / or forwarding the data to the Law Enforcement Monitoring Facility.

Description

technical field [0001] The invention relates to a method of providing access in a telecommunication system to data received from an interfacing traffic node in the system to a central storage medium. Background technique [0002] In data retention schemes, law enforcement authorities may request electronic service providers to retain specific data about specific persons, whereas data retention schemes provide for the retention of business data about all users of electronic services. Data preservation may at first appear to be an attractive strategic choice: the number of persons whose data will be retained and processed for law enforcement purposes would be substantially reduced under this choice, and thus the associated industry costs would be negligible. In fact, data preservation is a useful tool for law enforcement agencies. Undoubtedly, in those cases where suspects have been identified or in investigations such as organized criminal groups and terrorist organisations,...
