Embodiment Construction

[0020] figure 1 The functional architecture of a mobile node (1) in a Proxy Mobile Internet Protocol based network is shown.

[0021] Once the mobile node 1 enters the Mobile Agent Internet Protocol v6 domain 2 and attaches to the access link, after identifying the mobile node 1 and obtaining its identity, the mobile access gateway 3 (MAG) on the access link determines Whether the mobile node 1 is authorized for network-based mobility management services.

[0022] If Network 2 has determined that network-based mobility management services should be provided to this Mobile Node 1, then Network 2 ensures that Mobile Node 1 using any address configuration mechanism allowed by the network can obtain the address Move anywhere within the Internet Protocol domain.

[0023] The obtained address configuration may include an address (or addresses) from its home network prefix (or prefixes), a default router address on the link, and other related configuration parameters.

Abstract

The present invention discloses a legal listing method of an objective of a proxy mobile internet protocol network. A method of keeping the data and / or listening a target mobile node (1) of a proxy mobile internet protocol domain (2) connected to a telecom network through a mobile access gateway (3) in a telecom internet is provided for the law enforcement agency. The method comprises a step of configuring at least one of the mobile access gateway (3) and a local mobility anchor (4) as a listening control element (11) or a data keeping source to operate.

Description

technical field [0001] The present invention relates to methods and arrangements for providing hold or interception data to a lawful interception requesting entity in a telecommunications system. In particular, the present invention relates to Lawful Interception of Targets when using Proxy Mobile Internet Protocol based architectures and protocols in telecommunication networks. Background technique [0002] In many countries, operators and Internet service providers are obliged, upon legal request, to provide information on specific target subscribers upon request by authorities (law enforcement agencies) for detection, investigation and prosecution of crimes including terrorist acts and criminal offences. Business data, including stored data and the content of communications generated from public telecommunications and Internet services. [0003] These requirements have been met by methods and systems allowing lawful interception of targets in various 3GPP telecommunicati...
