Abstract: In one embodiment, a particular node joins a directed acyclic graph (DAG) in a computer network at a parent node, and determines its grade based on a topology of the DAG, the grade lower than the parent node and higher than any child nodes of the particular node. In response to detecting a trigger for a routing change in the DAG, the particular node delays the routing change based on the grade such that the delay is longer than a first associated delay of any of the child nodes and shorter than a second associated delay of the parent node. Upon expiration of the delay, the particular node may determine if the trigger for the routing change is still valid, and if valid, performs the routing change.

Abstract: An enhanced mobile communication device communicates directly with other enhanced mobile communication devices in an ad-hoc mode over a wireless medium. The device transmits and receives packets of digital data. The packets of digital data are such that when transmitted, the probability that they will be received by the other mobile communication devices is increased. The probability is further increased by transmitting the packets a multiple and variable number of times according activity in the wireless medium. Attempts to transmit are made periodically and the period of transmission is adjusted according to activity in the wireless medium. In a transportation application, the packets comprise vehicle traffic congestion update information. The device maintains a traffic database and a map database. Traffic congestion update information is exchanged with other devices.

Abstract: In a network processor, a “port-kind” identifier (ID) is assigned to each port. Parsing circuitry employs the port-kind ID to select the configuration information associate with a received packet. The port kind ID can also be stored at a data structure presented to software, along with a larger port number (indicating an interface and/or channel). Based on the port kind ID and extracted information about the packet, a backpressure ID is calculated for the packet. The backpressure ID is implemented to assign a priority to the packet, as well as determine whether a traffic threshold is exceeded, thereby enabling a backpressure signal to limit packet traffic associated with the particular backpressure ID.

Each instance is associated with a same user identifier identifying the same user, a first of the instances is associated with a first subidentifier, and a second of the instances is associated with a second subidentifier. The instances are configured so as, during an ongoing call conducted over a first network connection established based on the user identifier and the first sub-identifier, after the call has been answered, to establish a second network connection based on the user identifier and the second sub-identifier and to switch the call to the second network connection.

Abstract: Various techniques for exchanging control messages in order to gracefully reroute multicast traffic are disclosed. For example, one method involves sending a join message for a multicast group towards a root of a new multicast tree and forwarding multicast traffic, addressed to the multicast group, on a current multicast tree until an acknowledgment corresponding to the join message is received. The new multicast tree can be identified in response to detection of a topology change within the network. Until the acknowledgment is received, multicast traffic that is received via the new multicast tree can be dropped.

Abstract: A method of reducing transmission power is provided. In the method, a signal is transmitted by performing maximum power reduction (MPR) on maximum output power for the signal to be transmitted, when multi-cluster transmission is performed in a single component carrier. Here, the MPR is performed differently depending on a resource allocation ratio A. The resource allocation ratio A is defined as a ratio between NRB—agg and NRB—alloc. The NRB—agg represents the number of resource blocks (RBs) in a channel band, and the NRB—alloc represents the total number of RBs transmitted at the same time.

Abstract: The present invention enables automatic configuration of random access parameters. The base station is configured to control PRACH transmission of UEs, wherein the UE PRACH transmission comprises transmission of PRACH preambles constructed of root sequences. This is achieved by storing statistics associated with previous transmissions. A parameter associated with the construction of the PRACH is tuned based on the stored statistics. The base station controls the UE PRACH transmission by transmitting information to the UEs relating to the tuned parameter. This information is used by the UE when constructing the PRACH preambles. In this way, the cell parameters relating to random access can be improved to fit better to individual cells resulting in improved resource usage.
