Abstract: For logical multicasting in overlay networks, at a data processing system, an original unicast packet is received from a first component in a first computing node in an overlay network. To cause multicasting in the overlay network the received original unicast packet was unicast by the first computing node only to the data processing system, and a multicast data structure for the overlay network is maintained only by the data processing system, the multicast data structure containing information of each receiver that is configured to receive unicast packets during logical multicasting in the overlay network. From a set of subscriber receivers in the multicast data structure, a subset of the subscriber receivers is selected. A copy of the original unicast packet is unicast to each subscriber receiver in the subset.

Abstract: A method and system are provided for admitting new participants to an ongoing conference session. In one example, a conference server hosting a conference session may receive a request for a UE to join the ongoing conference session. In response to receiving such a request, the conference server may determine whether to admit the UE to the ongoing conference session as a full participant or as a partial participant. When the conference server determines to admit the UE as a full participant, the conference server establishes a conference leg with the UE and permits the UE to communicate with each and every current participant of the ongoing conference session. However, when the conference server determines to admit the UE as a partial participant, the conference server may establish a conference leg with the UE and may permit the UE to communicate with just some of the ongoing conference's current participants.

Abstract: Methods and apparatuses are provided for reducing power consumption by early decoding. It is determined whether a predetermined decoding condition is satisfied upon expiration of a time unit in a transmission time interval. Decoding is performed on a signal that has been received through the time unit in the transmission time interval, when the predetermined decoding condition is satisfied. A controller outputs an instruction signal to a RF processor to set to a low-power mode during a remaining time period of the transmission time interval after the time unit in the transmission time interval, when the decoding is successful. Decoding is performed on the signal that has been received through the RF processor upon expiration of a last time unit of the transmission time interval regardless of the predetermined decoding condition, when the time unit is the last time unit in the transmission time interval.

The wireless access gateway determines, based at least on the mobility tunnel, a VLAN of the WLAN access network that is uniquely associated in the wireless access gateway with a combination of the APN associated with the mobility tunnel and the mobile gateway. The wireless access gateway then forwards, to a wireless endpoint device, the packet on the VLAN.
