  • Patent number: 9942415
    Abstract: A Charging Data Function (CDF) unit of an Offline Charging System (OFCS) receives Accounting Charging Request (ACR) messages from Charging Trigger Functions (CTFs). The CDF stores ACRs in designated buckets based on the source CTF and its determined status. If there is no change in the status of the source CTF, the CDF continues to store ACRs as they are received in the designated bucket. If the source CTF status has changed (i.e., a reboot or restart has occurred), the CDF allocates a new bucket for the given CTF and stores ACR messages indicating the new status in the new bucket. In addition, the receiving CDF stops storing ACR messages in the previous bucket and deprecates it as being obsolete. The CDF processes the obsolete bucket to generate incomplete Charging Data Records (CDRs) for any ACRs for which complete CDRs cannot be generated.

  • Patent number: 9936520
    Abstract: A method for controlling a plurality of Wi-Fi clients and a plurality of Wi-Fi Access Points (APs) is provided. The method receives M1 and M2 for the Wi-Fi clients and M3 for the Wi-Fi APs. For a respective Wi-Fi client configured to operate on a channel, M1 is a Received Signal Strength Indication (RSSI) from a serving Wi-Fi AP and M2 is an aggregated level of interference from other than the serving Wi-Fi AP. For a respective Wi-Fi AP, M3 is a level of interference received from other of the Wi-Fi APs operating on the channel. The method generates distributions of M1, M2 and M3, sets a Clear Channel Assessment-Energy Detection (CCA-ED) threshold and a Clear Channel Assessment-Carrier Sense (CCA-CS) threshold based on the distributions of M1, M2 and M3, and transmits the thresholds to the Wi-Fi clients and Wi-Fi APs.

  • Publication number: 20180083716
    Abstract: We disclose a shaping encoder configured to use a variable-length shaping code to implement fixed-input fixed-output (FIFO) probabilistic signal shaping. In various embodiments, the variable-length shaping code can be a variable-input fixed-output code, a fixed-input variable-output code, or a variable-input variable-output code. The FIFO functionality of the shaping encoder is enabled by a control circuit that operates to: (i) check an output-overflow condition for each bit-word to be encoded using the variable-length shaping code and (ii) switch the shaping encoder from using the variable-length shaping code to using a suitable FIFO code if the output-overflow condition is satisfied. Some embodiments of the shaping encoder can incorporate a conventional FEC encoder in a manner that substantially preserves the shaping gain realized by the shaping encoder.

In one aspect a set of unique features are determined from a collection of electronic objects. A graph is constructed in which electronic object are represented as object nodes and determined features are represented as feature nodes. The object nodes are interconnected by a weighted edge to at least one feature node. Scores for the object nodes and the feature nodes are computed using a determined set of anchor nodes and a determined weighted adjacency matrix. The object nodes and the feature nodes of the graph are ranked and displayed based on the computed scores.

    Abstract: The present disclosure generally discloses a congestion control capability for use in communication systems (e.g., to provide congestion control over wireless links in wireless systems, over wireline links in wireline systems, and so forth). The congestion control capability may be configured to provide congestion control for a transport flow of a transport connection, sent from a transport flow sender to a transport flow receiver, based on flow control associated with the transport flow. The transport flow may traverse a flow queue of a link buffer of a link endpoint. The link endpoint may provide to the transport flow sender, via an off-band signaling channel, an indication of the saturation state of the flow queue of the transport flow. The transport flow sender may control transmission of packets of the transport flow based on the indication of the saturation state of the flow queue of the transport flow.

  • Patent number: 9924370
    Abstract: Systems, methods, and software for controlling transmissions of User Equipment (UE) on an unlicensed spectrum. In one embodiment, a base station communicates with the UE through radio communications on a licensed spectrum of a carrier. The base station transmits a query to a policy control element requesting spectrum selection criteria for the UE over a direct interface. The base station receives a response from the policy control element that includes the spectrum selection criteria for the UE, and processes the spectrum selection criteria to allocate resources for transmissions involving the UE on the licensed spectrum and on the unlicensed spectrum. The base station then provides a control message including the allocated resources towards the UE to enable the UE to perform the transmissions on the unlicensed spectrum, the licensed spectrum, or a combination of the two.
