The method includes transmitting a request message to a base station to request to count the number of terminals currently being provided with one or more multicast/broadcast services or interested in the multicast/broadcast services; and switching mode of a corresponding service to unicast mode or multicast/broadcast mode according to whether the number of counted terminals is greater than a predefined threshold wherein the number of counted terminals is contained in a message received from the base station as a response to the request message. | 2014-09-11 |
20140254457 | METHOD AND APPARATUS FOR RESOLVING CALL COLLISIONS IN A DIGITAL CONVENTIONAL DIRECT MODE - A process for resolving call collisions in a digital conventional direct mode includes monitoring a direct mode communication channel for transmissions from other direct mode radios in the plurality of direct mode radios. In response to detecting a new call request: identifying a last radio to transmit on the direct mode channel, transmitting a new call request for receipt by the last direct mode radio to transmit, monitoring the direct mode channel for a response from the last radio to transmit, and if a call grant granting the new call request is received from the last radio to transmit, initiating the new direct mode call on the direct mode communication channel. If the call grant is not received, at least temporarily refraining from initiating the new direct mode call. | 2014-09-11 |

20140254459 | COCKTAIL PARTY: SIDE CONVERSATIONS AND TALKING OVER IN WIRELESS MESH NETWORKS - The present disclosure proposes a method for minor modifications to the Distributed Coordination Function (DCF) channel access mechanism in order to enable a greater number of concurrent communications in a unit area in compliance with the current protocol design. The method comprises equipping nodes with wider neighborhood information than what is obtained with IEEE 802.11, and with a device calibration that equips the device with the knowledge of its performance in the presence of interference. The present disclosure medium access mechanism increases the aggregate throughput with every additional concurrent communication that is enabled in the shared medium. Cocktail Party-capable devices can fairly coexist with 802.11 legacy DCF devices, and co-operate with these devices in the same network without changes to those devices or to the standard. The same or similar mechanisms can be applied to other systems and standards in order to enable concurrent communications in the same contention area. | 2014-09-11 |
