Description

TECHNICAL FIELD The present disclosure relates to the technical field of communications, and in particular, to information communication methods, communication devices and processor-readable storage media. BACKGROUND As an object and a guidance for performing an intelligent network optimization control by a near real time radio access network intelligent controller (Near Real Time RAN Intelligent Controller, Near-RT RIC), The A1 policy may directly affect the result of the optimization control on the radio network performed by the Near-RT RIC. In related technology, the A1 policy is only limited to indexes including quality of service (Quality of Service, QoS), quality of experience (Quality of Experience, QoE) and traffic steering preference (traffic steering preference). These indexes cannot meet various service requirements and system requirements of the radio network, so that the Near-RT RIC lacks of a capability for flexibly ensuring the resource optimization. EP3675549A1 discloses a network slice management method, including: obtaining, by a network management unit, capability description information of a network slice, where the capability description information of the network slice includes at least one of a feature of the network slice and a deployment capability of the network slice; and sending, by the network management unit, a notification message carrying the capability description information of the network slice, to a service management unit. US2020329381A1 discloses methods for orchestration and configuration of end-to-end network slices across a 3GPP core network and ORAN. The network includes a NSMF that receives an AllocateNSI operation with attributes to allocate an NSI. The AllocateNSI operation includes an attributeListIn parameter that specifies network slice properties in a ServiceProfile to be supported by the NSI. The NSMF determines that a new NSI is to be created rather than using an existing NSI and that the new NSI is to contain a NSSI (RAN) and a NSSI (CN). The NSMF communicates with a NSSMF (RAN) and NSSMF (CN) to create the new NSI. The new NSI includes an O-CU-CP, O-CU-UP and O-DU VNFs, and an O-RU PNF for the NSSI (RAN), and UPF, AMF, and SMF VNFs for the NSSI (CN). EP3709708 A1 discloses an apparatus comprising means configured for: receiving, from an apparatus associated with a radio cell, data specifying cell level parameters and computing resources availability, selecting, based on the cell level parameters and computing resources availability, a set of radio resources management algorithms, sending, to the apparatus associated with the radio cell, data specifying the selected set of radio resources management algorithms. Further prior art is found in document WO2020040723 A1. SUMMARY The present disclosure is to provide information communication methods, communication devices and processor-readable storage media as defined in the appended set of claims, so as to address the issue in the related art that the A1 policy cannot meet various service requirements and system requirements of the radio network, so that the Near-RT RIC lacks of a capability for flexibly ensuring the resource optimization. The technical solution of the present disclosure has at least the following beneficial effects. In the technical solution of the embodiment of the present disclosure, the target policy information is obtained and then the target policy information is sent to the second communications device, the target policy information including at least one of the following: a reliability index for indicating a success probability of data transmission; a bandwidth index for indicating a system bandwidth; or a spectral efficiency index for indicating a spectral efficiency. As such, by using the new target policy information, the policy management capability can be improved to meet the various service requirements and the system requirements of the radio network, thereby improving the capability of controlling and optimizing the radio network by the communications device.
