Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.

Abstract: This disclosure presents several embodiments of a device configured to perform inband telemetry tracking. The device is configured to store a flow table that tracks metrics of a detected packet flow that passes through the device. More specifically, the flow table tracks several telemetry metrics, each telemetry metric being specific to a tracking time period, and tracking statics based only on packets of the packet flow that were received during that specific time period. At an end of an export time period (which is longer than a tracking time period), the device transmits all stored telemetry metrics from the flow table to a collector.

Abstract: Methods, systems, and devices for wireless communications are described that provide for system information (SI) for access and backhaul. An access node (AN) may provide SI to devices within its cell indicating communication procedure configurations. The AN may provide SI to devices that is specific to whether the communication procedure is an access procedure or a backhaul procedure. The AN may transmit a common master information block (MIB) directing the devices within its cell to a search space in order to receive the remaining SI. The search space may be shared between access devices and backhaul devices or alternatively may be separate between access and backhaul devices. The remaining SI may not be shared between access and backhaul devices. The devices may determine different configurations as defined by the SI from the AN for communications procedures based on whether the procedure is an access procedure or a backhaul procedure.

Abstract: In a system and method for transporting SMS message between sending MNO and receiving MNO, wherein the receiving MNO uses a sponsor, a component is provided either in the network of the receiving MNO or, preferably, at the carrier of the receiving MNO. The component is in the routing path between the sending MNO and the routing MNO and/or in the return path and preferably in both paths. The component (WB) manages and enforces the proper SMS delivery methods to the receiving MNO by introducing itself in the SRI for the SMS request as a sending party, using a sponsored network entity (SMSC-WB), and/or introducing itself in the SRI of the SMS response message as a receiving party using a sponsored network identity (VMSC-WB, HLR-WB).
