Title |
Lawful Interception (LI); Internal Network Interfaces; Part 2: X2/X3 |
||||||
Scope and Field of Application |
The internal network interface covers wide area connections between LI systems and (depending on the network) a large number of network elements from different vendors. Nearly every network element has its own interface with different transport protocols, authentication (if any), encryption (if any), commands etc. This makes every new connection highly complicated and costly. The interfaces between Administration and Mediation Functions are usually proprietary and implemented internally within a product for LI and therefore need not be compatible between products of different vendors. Traditionally internal interfaces have not been standardized. Given the experience of standardization in HI2 and HI3 industry has received benefits from this by way of interoperability, security and cost reduction. This WI does not intend to force compatibility on legacy equipment although should that be possible it will be welcomed. The initial focus is on newer IP related systems (but not limited to IP). With a view to the future, as network and services become virtualized this WI intends to support newer implementations by ensuring a standard interface is available for the provisioning of equipment or service. The DF/MF (delivery / mediation function) translates network internal X2/3 messages to HI2/3 (standardized handover interface to the LEMF). This function allows insulation for the CSP to manage their network appropriately without untoward impact on the LEMF. This revision is to make an editorial correction. |
