摘要： A method for time sensitive network (TSN) operation includes: in the case of data traffic stoppage in a communication channel of TSN due to at least one of down time of a user plane (UP) connection and a reset of the UP connection, performing the following: generating, by a user plane function (UPF), an audit report about the at least one of the down time and the reset; sending, by the UPF, the audit report to a first element in control plane (CP), without waiting for communication from the CP; and determining, by one of the first element or a second element in the CP, survival time of the communication channel. The audit report is sent along with a report type indicating the down time of the UP connection due to connection fluctuation or a switch-over of the UP connection from a primary UPF to a backup UPF.

摘要： Minimizing signaling traffic between a User Plane (UP) and a Control Plane (CP), where Policy and Charging Function / Policy and Charging Rule Function (PCF/PCRF) software transmits a first and a second Policy and Charging Control rule (PCCRule1 and PCCRule2) to CP equipment. The CP equipment installs both PCCRule1 and PCCRule2 on UP equipment as UPRule1 and UPRule2 respectively, where UPRule1 is set as active during a first time period and the UPRule2 set as active during a second time period. User Plane Function (UPF) software matching data traffic with a Packet Detection Rule (PDR) to generate identified traffic during the first and second time periods and automatically redirecting data traffic to a predetermined location at the expiration of the first and second time periods respectively. UPRule1 and UPRule2 are automatically enabled and disabled alternatively after expiration of their respective timers by the UPF software.

摘要： There is provided a method for a session audit in a communication system having a first plane and a second plane. The method can be employed in a case in which the first plane is a control plane and the second plane is a user plane, or a case in which the first plane is a user plane and the second plane is a control plane. The first plane performs operations of (1) sending to the second plane, an association update request that contains a first vendor-specific information element (IE) having (a) a bit set to indicate a desire for a single control plane (CP) fully-qualified session identification (CP F-SEID), and (b) a CP F-SEID, and (2) receiving from the second plane, an association update response that contains a second vendor-specific IE having (a) the CP F-SEID, and (b) a mapped user plane (UP) fully-qualified session identification (UP F-SEID).

摘要： A Shared Cell (SC) Controller uses deployment information, radio resource utilization measurements, cell load measurements, signal quality measurement, operator's policies and radio capabilities to make decisions on system configuration, re-configuration, and channel allocation related to the Shared Cell groups. The SC Controller may also use artificial intelligence/machine learning to predict future system state when making decisions on system configuration and channel allocation. The SC Controller can be implemented in the context of using a CBRS system, the ORAN architecture, and the Shared Cell group of Radio Units (RUs). SC Controller can be implemented as part of the Non-Real Time Radio Intelligent Controller (Non-RT RIC). The SC Controller interfaces with the Citizens Broadband Radio Service Device (CBSD) Controller, and the SC Controller sends the Shared Cell group information to the O-RU Controller so that the O-RU Controller can configure the radio components.
