Abstract:
An improved lawful intercept (LI) infrastructure is described. In response to a valid LI provisioning request, a subscriber management component statically allocates a user equipment (UE) subject to the LI provisioning request to an edge location comprising a high-speed gateway and a Mediation and Delivery Function (MDF), which coordinates the delivery of intercepted communications. The subscriber management component maintains this allocation for the life of the LI provisioning request and reverses the UE to a dynamic gateway allocation scheme when the LI provisioning request ends. As a result, only a subset of edge locations must be equipped with MDFs, and the handover is transparent to the UE.
