The network node then receives an upstream fast notification packet (UFNP) from the merge node. The network node modifies its forwarding information upon receipt of the UFNP such that the multicast data is to be received by the network node from its downstream via which the UFNP was received. The DFNP and the UFNP cause the multicast data to reverse its flow direction between the network node and the merge node. | 2013-12-05 |

20130322247 | ENHANCING AQM TO COMBAT WIRELESS LOSSES - In order to maintain a small, stable backlog at an internet router buffer, active queue management (AQM) algorithms drop packets probabilistically at the onset of congestion.

20130322268 | Long Term Evolution Network Billing Management - A device in a network may monitor a communications session (such as a traffic flow) and determine that the session has been affected by an adverse network condition such as equipment failure or heavy congestion. The effect of the network condition may be provided to a billing system that may proactively adjust charging for a customer associated with the traffic flow. Various data may be taken into account in determining the adjustment, including a service type, a subscriber identifier, an emergency identifier, and a traffic condition index. | 2013-12-05 |
20130322269 | METHOD AND APPARATUS FOR AUTOMATIC GAIN CONTROL IN A TD-LTE SYSTEM - This invention describes method and apparatus for automatic gain control (AGC) for a TD-LTE system, taking into consideration the TD-LTE frame structure. In one embodiment, an AGC method comprises: adjusting RF gain for subframe j (where 0<=j<=9) in a radio frame according to an average peak signal power of subframe j in previous radio frames when a terminal is lack of information in downlink timing and in uplink/downlink configuration; computing a first average signal power in one or more downlink subframes as received from at least one base station when the terminal has information in downlink timing but is lack of information in uplink/downlink configuration; and computing a second average signal power in one or more downlink subframes as received from at least one base station when the terminal has information in downlink timing and in uplink/downlink configuration. | 2013-12-05 |
20130322270 | Techniques for Segregating Circuit-Switched Traffic from Packet-Switched Traffic in Radio Access Networks - A computer-based method for processing user data traffic in a RAN in which mobile user equipment can communicate with a RNC through a base station includes the following steps. A flow of data frames to/from mobile user equipment passing between the base station and the RNC are read, wherein one or more of the data frames contain control messages and one or more other of the data frames contain user data. The control messages contained in the data frames are analyzed for channel identification information that indicates whether the data frames that contain user data contain circuit-switched or packet-switched user data. The data frames that contain the circuit-switched user data and the data frames that contain the packet-switched user data are segregated at a transport network layer between the base station and the RNC based on the channel identification information. | 2013-12-05 |
20130322271 | SYSTEM FOR PERFORMING DATA CUT-THROUGH - A system transfers data. The system includes an ingress node transferring data at a determined bandwidth. The ingress node includes a buffer and operates based on a monitored node parameter. The system includes a controller in communication with the ingress node. The controller is configured to allocate, based on the monitored node parameter, an amount of the determined bandwidth for directly transferring data to bypass the buffer of the ingress node. | 2013-12-05 |
