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.

Abstract: A first cell device obtains, from a second cell device, multicast information associated with the second cell device, where a first wireless coverage area associated with the first cell device at least partially overlaps a second wireless coverage area associated with the second cell device. The first cell device transmits the multicast information to an element management system, and receives, from the element management system, an instruction, generated based at least on the multicast information, to not use one or more subframes, associated with a multicast transmission session associated with the second cell device, to transmit during the multicast transmission session. The first cell device determines, after receiving the instruction, that the multicast transmission session has been initiated, and causes the first cell device to not use the one or more subframes to transmit during the multicast transmission session associated with the second cell device.
