    摘要： A method for stale user context detection and removal is implemented at one of Open Radio Access Network (O-RAN) Centralized Unit (gNB-CU) or Distributed Unit (gNB-DU). In a first variant which utilizes the gNB-CU, the gNB runs a configurable periodic timer for initiating the stale UE detection procedure, i.e., the gNB configures, for every UE context stored in its database, a special Event A1 with the low a1-Threshold = -120 dBm, reportlnterval = 512 ms, and reportAmount = 2. In a second variant which utilizes the gNB-CU, stale UE detection mechanism can be based on a periodic Event A1 configured during initial User admission procedure, i.e., the gNB configures a special Event A1 with the low a1-Threshold = -120 dBm, reportInterval = 1 minute, and reportAmount = infinity. In a further variant, stale UE contexts can be identified at the gNB-DU based on periodic Channel State Information (CSI) reports.

    摘要： The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate after a 4th generation (4G) communication system such as long-term evolution (LTE). According to various embodiments of the disclosure, a method performed by a distributed unit (DU) may include: transmitting, to a near-real time (near-RT) radio access network (RAN) intelligent controller (RIC), an E2 report message including resource policy information related to a shared resource, a prioritized resource, and a dedicated resource of a radio resource for a rRMPolicyMemberList; and receiving, from the near-RT RIC, an E2 control message generated based on the resource policy information; wherein the resource policy information includes an rRMPolicyMaxRatio, an rRMPolicyMinRatio and an rRMPolicyDedicatedRatio, and wherein each of the rRMPolicyMaxRatio, the rRMPolicyMinRatio and the rRMPolicyDedicatedRatio are indicated with an integer between 0 and 100.

    摘要： A radio access network control apparatus has at least one processor that performs: acquiring operational states of a plurality of radio access network nodes from a virtual infrastructure that virtually manages a set of the plurality of radio access network nodes; acquiring measured operational data from each of the radio access network nodes; and issuing an operational policy concerning the operation of each of the radio access network nodes, to at least one of the virtual infrastructure and each of the radio access network nodes, based on the operational state and the operational data. The issuing the operational policy includes issuing a resource allocation policy concerning the resource allocation of the plurality of radio access network nodes to the virtual infrastructure, and a traffic control policy concerning the traffic control of each of the radio access network nodes to each of the radio access network nodes.

    摘要： The present disclosure relates to a 5 th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than 4 th generation (4G) communication systems such as long term evolution (LTE). According to embodiments of the present disclosure, a method performed by an E2 node comprises a step of transmitting a radio access network (RAN) intelligent controller (RIC) indication message to a RIC, wherein the RIC indication message comprises an E2 service model (E2SM)-KPM indication message format 1 and an E2SM-KPM indication message format 2 for key performance measurement (KPM), the E2SM-KPM indication message format 1 does not comprise terminal identification information, and the E2SM-KPM indication message format 2 comprises terminal identification information. According to embodiments of the present disclosure, the method performed by the E2 node comprises a step of receiving a radio access network (RAN) intelligent controller (RIC) control message from the RIC, wherein the RIC control message can comprise slice identification information and control information with respect to a network slice corresponding to the slice identification information.
