METHOD FOR PROVIDING A LAW ENFORCEMENT AGENCY WITH SAMPLED CONTENT OF COMMUNICATIONS

摘要

Presented are a method and a node in a Lawful Interception (LI) network, in which the node is configured to provide a Law Enforcement Agency with Intercept Related Information (IRI) and Content of Communications (CC) of data traffic in a digital communications network. The IRI and CC are forwarded to an Intercept Mediation and Delivery unit node (IMDU) of the LI network, wherein the IMDU is configured to sample the content of communications according a certain sampling rate to achieve one or more samples of the CC, and to forward the generated one or more samples to the Law Enforcement Agency.

1. A method in an Intercept Mediation and Delivery unit (IMDU) node in a Lawful Interception (LI) network for providing a Law Enforcement Agency with Intercept Related Information (IRI) and Content of Communications (CC) from data traffic in a digital communications network, said data traffic being related to one or more target identities and interceptable by an Intercepting Control Element in a common node of said LI network and digital communications network, wherein said Intercepting Control Element being configured to receive a request to intercept data traffic related to one or more target identities, collect IRI and CC related to said one or more requested target identities, and forward the IRI and CC to an Intercept Mediation and Delivery unit node of the LI network, the method comprising:
receiving the IRI and CC from said Intercepting Control Element; sampling the CC according a certain sampling rate to achieve one or more samples; and forwarding the generated one or more samples to the Law Enforcement Agency.
