Abstract: Systems and techniques for routing frames in one or more radio access networks based on a physical addressing scheme involve assigning a unique identifier to a virtual local area network that includes a path connecting an access point to a radio network serving node. For each of multiple nodes in the radio access network, the virtual local area network is associated with a port for routing frames towards the radio network serving node and/or a port for routing frames towards the access point. Frames that include a destination address associated with a mobile station associated with the access point are unicast from the radio network serving node towards the access point using the virtual local area network.

Abstract: A device is dedicated to synchronizing radio access logic entities each having a local clock and forming part of a wireless communication network capable of broadcasting and/or multicasting content-defining data packets between a broadcast and/or multicast source and mobile communication terminals, via logic entities. This device includes a calculation unit tasked with i) estimating, for each logic entity of a synchronization area of the network, the time, with respect to a reference clock when said entity received a selected packet from the broadcast and/or multicast source, then ii) determining, for each logic entity, a value that represents the time difference between its reception time and the latest reception time among those of the logic entities, and iii) ordering each logic entity to wait for a period of time equal to the value which was determined for it before retransmitting each packet received from the broadcast and/or multicast source to the terminals located within its synchronization area.

Abstract: Disclosed is a method for providing information related to available broadcast programs, such as Electronic Program Guides or parts thereof, in a mobile communication network comprising a plurality of cells, with respective base stations. The cells with their base stations are part of a broadcast zone managed by a server. The server identifies the available broadcast programs and transmits the information via the base stations to access terminals that are serviced by those base stations. The base stations establish a specific EPG broadcast connection and transmit the information to the access terminals being serviced by them, over the specific EPG broadcast connection.

The convergence sub layer (3) is preferably arranged to process the user defined information for univocally identifying the predefined connection in combination with the information contained in the packets.
