Anti-spoofing techniques for outbound telephone calls
Techniques are disclosed for verifying a caller ID field of an outbound telephone call. A termination service provider call server receives a call request from a calling endpoint that includes a called endpoint telephone number, and a caller ID telephone number. The termination service provider call server determines a calling endpoint telephone number assigned to the calling endpoint and creates an “in use” message comprising the calling endpoint telephone number and a timestamp of when the call request was received. The “in use” message is forwarded to an active call database before forwarding the call request to an inbound carrier call server servicing the called endpoint telephone number. The inbound carrier call server receives the call request intended and sends a query to the active call database to determine whether the caller ID telephone number in the call request is currently in use. The active call database sets the status of telephone numbers contained in all received “in use” messages to in use. It then determines whether the caller ID telephone number received in the query from the inbound carrier call server corresponds to a telephone number that is currently in use. If the caller ID telephone number does not correspond to a telephone number that is currently in use, the active call database returns a fail message to the inbound carrier call server. If the caller ID telephone number does correspond to a telephone number that is currently in use but the timestamps for the call request and the query differ by more than a predetermined duration, it returns a fail message to the inbound carrier call server. If the timestamps for the call request and the query are within the predetermined duration, it returns a pass message to the inbound carrier call server. The inbound carrier call server either routes or does not route the call request to the called endpoint depending on the query results.

Transmit diversity from orthogonal design for FBMC/OQAM
How to apply an Alamouti like space-time coding (or transmit diversity) to a Filter Bank Multicarrier (FBMC) transmission using Offset QAM (OQAM). In FBMC, due to the orthogonality in the real domain only, an intrinsic interference results thereof for the imaginary component. Simply adapting the Alamouti scheme to FBMC OQAM is not obvious since the intrinsic interference terms are not equivalent at each antenna since it depends on the surrounding symbols. The application proposes to use a precoding symbol chosen to cancel out (zero) the intrinsic interference individually for each antenna, ie a code rate of 1/2 (sending one data symbol requires two time units). A more elaborated embodiment proposes to choose the contiguous precoding symbols such that a virtual QAM Alamouti scheme is achieved, without rate loss.

Reconfiguration of active component carrier set in multi-carrier wireless systems
In a multi-carrier wireless system, potential problems from reconfiguring mobile station resources to accommodate changes in component-carrier configuration are mitigated by inserting a guard period each time the configuration of component carriers changes, so that transceiver reconfiguration can be carried out without interfering with ongoing transmission.

The base station then refrains from transmitting data to the mobile station during a pre-determined guard interval of at least one transmission-time interval subsequent to the signaling of the change of configuration. After the guard interval, data is transmitted to the mobile station according to the second component carrier configuration.

Managing tunnel endpoints for facilitating creation of logical networks
Some embodiments provide a novel method for managing hardware forwarding elements (MHFEs) that facilitate the creation of multiple logical networks on a set of shared physical forwarding elements. The method uses a set of logical controllers that generate data that defines a set of logical networks, and a set physical controllers to distribute the generated data to the hardware forwarding elements. In some embodiments, each MHFE can serve as either a master WIFE or a slave MHFE for one set of computing end nodes (e.g., VMs, containers, etc.) in a logical network. To ensure proper routing of data packets to the computing end nodes, each MHFE sends to its physical controller an inventory (e.g., a table, a list, etc.) of the set of computing end nodes for which it serves as the master MHFE or the slave MHFE. Each physical controller forwards the inventory for each logical network to the logical controller for the logical network. Each logical controller maintains the master inventory of the MHFEs that are masters (and slaves if applicable) of the various compute end nodes of each logical network managed by the logical controller. After receiving a new inventory from a physical controller, the logical controller updates its records, resolves any conflicts while it is updating its records, and distributes one or more master/slave inventories for one or more logical networks that it manages to the physical controllers, which, in turn, pass this information to the MHFEs that they manage.
