Quality of service rule management in 5G
A method of managing default QoS rules for PDU session is proposed. A PDU session defines the association between the UE and the data network that provides a PDU connectivity service. Each PDU session is identified by a PDU session ID, and may include multiple QoS flows and QoS rules. There can be more than one QoS rule associated with the same QoS flow. A default QoS rule is required to be sent to the UE for every PDU session establishment and it is associated with a QoS flow. Within a PDU session, there should be one and only one default QoS rule.

Bearer translation
A method for default bearer translation with GBR bearer translation. A GBR bearer is known in UE, 5G-RAN, and SMFs from the existing QoS flow parameters from one or more QoS flows for a PDU session that includes an assigned value for guaranteed bit rate. In case a PDU session has multiple associated QoS flows that each include an assigned value for GBR, then each flow is determined as a candidate GBR bearer for the target E-UTRAN access. Each GBR bearer candidate is arranged in a priority order based on, for example, the QoS flow parameters (e.g., ARP), and the resulting EPS QCI when translating QoS flow parameters in 5G to a 4G representation. Hence common priority rules for 1:1 mapping between 5G representation and 4G representation can be used by the nodes having knowledge of the PDU session and the QoS flows characterized as GBR QoS flows. |

In-service quality monitoring system with intelligent retransmission and interpolation
A service request for communication services for communication clients is received. In response, a communication service network is set up to support the communication services. Routing metadata is generated for each of the communication clients. The routing metadata is to be used by each of the communication clients for sharing service quality information with a respective peer communication client over a light-weight peer-to-peer (P2P) network.

Cascade echo cancellation for asymmetric references
A system configured to perform cascade echo cancellation processing to improve a performance when reference signals are asymmetric (e.g., dominant reference signal(s) overshadow weak reference signal(s)). The system may perform cascade echo cancellation processing to separately adapt filter coefficients between the dominant reference signal(s) and the weak reference signal(s). For example, the system may use a dominant reference signal to process a microphone audio signal and generate a residual audio signal, using the residual audio signal to adapt first filter coefficient values corresponding to the dominant reference signal. Separately, the system may use a weak reference signal to process the residual audio signal and generate an output audio signal, using the output audio signal to adapt second filter coefficient values corresponding to the weak reference signal. |
