Abstract: A novel method of operating a Distributed Cable Modem Termination System is provided. Each branch CMTS node in a distributed CMTS supports a complete CMTS system and with full-spectrum ports. One or more MAC domains are defined at each branch CMTS node. A MAC domain defined at a branch CMTS node includes only service flows of the CMs that are connected to the branch CMTS node. Identifiers of service flows coming from a branch CMTS node are always unique, i.e., two different service flows of the branch CMTS would always have different SIDs, even if they belong to different MAC domains. On the other hand, service flows belonging to different branch CMTS nodes are free to reuse the same identifiers.

Abstract: Apparatus and methods that offload charging from an Online Charging System (OCS). The OCS includes an offload controller that receives a online charging request from a policy enforcement element for a service, determines whether charging for the service is eligible to be offloaded from the OCS to an Offline Charging System (OFCS), and pushes a charging rule to the policy enforcement element to switch a charging mode for the service to offline charging. An online charging function within the OCS receives another online charging request for the service from the OFCS that reports a charging event detected by the policy enforcement element, and debits an account of an end user based on the online charging request from the OFCS.

Abstract: A method to extend the downstream and upstream data carrying capability of an HFC CATV system. At the neighborhood level, the CATV cable (the primary channel) is divided into different segments connected by electrically active junctions. At the junctions, each segment is also connected to a secondary data channel, such as an optical fiber or ultrahigh RF frequency (1 GHz+) secondary channel, which can carry supplemental downstream narrowcast channels and upstream channels between a plurality of such CATV cable segments. At the junctions, some CATV primary channel RF signals such as broadcast channels are passed without interference, while certain primary channel downstream narrowcast RF channels and upstream narrowcast RF channels are precisely suppressed using adaptive cancelling methods. Such adaptive cancellation methods are superior to prior art lowpass, highpass, and bandpass filtering methods because they allow for more efficient use of limited CATV primary channel RF spectrum.

Abstract: The controlling of an operation of an application is implemented in a communication network by obtaining network identification and cell load information for a bearer in order to compute an actual transport block size per physical resource block (ATpP) slope for the bearer. A user equipment (UE) location corresponding to the bearer is associated with geographic pixel information in order to calculate an interference vector. The interference vector is used to compute a coverage map tuple that is used to control the operation of the application. Throughput can also be predicted using the coverage map tuple.

Abstract: Producing advanced HFC CATV cable systems while easing the burden of backward compatibility. The system improves CATV data carrying capacity by moving RF QAM modulators from the cable head end to various individually or group addressed optical fiber nodes supplying neighborhood CATV cables, and sending data from the cable head IP backbone to the nodes over optical fiber as IP data packets. For high backward compatibility, the system digitizes legacy RF waveforms, or demodulates legacy QAM waveforms to QAM symbols, also transmits these over the optical fiber as IP data packets, and then reconstitutes back to original waveforms as needed. The system is thus able to easily handle legacy NTSC, FM, QPSK waveforms and do partial (QAM symbol level) compression of legacy QAM waveforms to and from multiple nodes without requiring additional optical fiber wavelengths. The system may use non-standard upstream/downstream CATV frequency splits, filter bank receivers, and FPGA/DSP/ASIC methods.

Abstract: Communication networks and methods are disclosed for performing online charging in LTE/EPC communication networks. In an LTE/EPC communication network, one or more LTE network elements connect to an Online Charging System (OCS) over an enhanced interface. The LTE network element that is serving a session for a mobile device triggers on a charging event, and generates a credit request message (e.g., Diameter CCR). The LTE network element identifies access information for the session indicating the type of access for the mobile device to the LTE/EPC communication network, and inserts the access information in the credit request message. Through the enhanced interface, the LTE network element is able to transmit the credit request message to the OCS with the access information. The access information may then be used in the OCS to determine a more accurate charging rate for the session.
