Abstract: For monitoring a wireless line usage status more effectively, a mobile station extracts a synchronizing signal of each of frames received from a plurality of base stations and a known signal transmitted together with transmission data within a time slot in which the transmission data are included but not transmitted within a time slot in which the transmission data are not included. The mobile station then measures a reception power of the synchronizing signal and a reception power of the known signal for each base station. And the mobile station determines a usage status of a wireless line of each base station based on the reception power of the synchronizing signal and the reception power of the known signal.

Abstract: Various systems and methods for detecting a deviation of an existing connectivity of a data center from a pre-determined connectivity are presented. One method involves detecting a deviation of an existing connectivity of a data center from a pre-determined connectivity by defining a start node. The start node is defined based on a condition of a component of the data center. The condition is determined based on an explicit relationship between a node and another node of the data center. The method involves conditionally matching a sub-graph and a portion of a main graph by identifying the deviation. The conditional matching is begun at the start node. A failure to conditionally match a portion of the sub-graph and a portion of the main-graph indicates that the deviation exists.

Abstract: In one aspect, the teachings herein provide point-to-point communication between all the virtual machines (VMs) belonging to the same tenant in a cloud-based virtual network environment without using any intermediate routing functions, and while providing full virtualization at the L2 and L3 levels. That is, the approach preserves completely isolated address spaces for each tenant at both L2 and L3 levels and supports multiple subnets for each tenant, and thereby allows tenants to define their own virtual networks without requiring the addition of expensive centralized routing and without requiring inter-subnet communications for the same tenant to traverse sub-optimal paths, as happens with software-based routers implemented in one of the VMs belonging to the tenant.

Abstract: Passive advertising via a video display unit or radio passive advertising is performed through the insertion of commercials at specific time locations based on signaling provided in a video or audio broadcast stream. However, such advertising systems do not take advantage of a recipient's first impulse to react to the advertisement, thereby losing a potential sale. Embodiments disclosed herein provide a recipient of a video display or radio broadcasts with real-time information on products (e.g., goods or services) placed in the video display or radio broadcasts. In addition, embodiments provide the recipient with a real-time opportunity to gather information or to respond to requests (e.g., marketing requests) at the time associated with the recipient's initial impulse to act in response to receiving the video display or radio broadcast.

A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference.

Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.

Abstract: Training, refreshing and/or updating Ethernet link partners for silent channels and/or silent directions of channels may be determined based on control parameters. This may be used to improve energy efficiency in Ethernet communication. Control parameters may comprise a default value and/or may be determined based on prior training, refreshing and/or updating.

After the training, refreshing and/or updating, the silent channels may transition to active and/or may remain silent.

Abstract: An Ethernet link may comprise silent and active channels and may support energy efficient Ethernet communication. Training parameters from the one or more active channels may be utilized for determining and/or adjusting training parameters for silent channels prior to activation. Training parameters for silent channels may be determined based on copying training parameters from active channels. Determination of training parameters for silent channels may be based on a weighted average of the active channel training parameters. A delta between active channel training parameters from a prior time and subsequent time may be utilized to determine a correction factor for adjusting training parameters for a silent channel from a prior time. Silent channels may be adjusted based on active channel training parameters and then subsequently may be trained. Training parameters may be adjusted for one or more of an echo canceler, a near-end crosstalk canceler and a far-end canceler.
