Abstract: A network layer device controls provision of data link layer functionality by a data link layer device to provide a requested multimedia service to a subscriber. For example, the network layer device may control the performance of multicast elaboration by the data link layer device, or the queuing and forwarding of packets by the data link layer device to facilitate transmission of packets according to a Quality of Service class. The network layer device may send control messages to the data link layer device to dynamically configure a control object stored by the data link layer device, such as multicast filter information or a Quality of Service profile. The network layer device may be a service edge router, and the data link layer device may be a customer premises equipment device, e.g., a modem or wireless access point, or a switch, e.g., a digital subscriber line access multiplier.

Abstract: A communications system includes a base station and mobile terminals. Voice data are transmitted within data packets in asynchronous transmission. The base station has an air interface for implementing first partial connections to the mobile terminals and a network interface to a communication network via which second partial connections to further terminals can be implemented. The base station also contains a router for allocating data packets which arrive in existing first or second partial connections to second or first partial connections. The allocation is done in dependence on an address information item which specifies a terminal in the sense of a transmission destination and is in each case contained in the individual data packets. The mobile terminals also contain in each case a voice compression device and/or a voice decompression device.
