Abstract: Provided are a handover method, a handover device, and a network system. The handover method includes: receiving cell information of a second cell sent by a second network element, wherein the second cell is a cell managed by the second network element, and the cell information includes predicted cell load information of the second cell; and sending a handover instruction to a terminal in a case where the cell information satisfies a preset condition, wherein the handover instruction is used for instructing the terminal to perform handover to the second cell, and the case where the cell information satisfies the preset condition at least indicates that the predicted cell load information of the second cell is lower than a configured first threshold.

Abstract: Provided are a method and a device for load information interaction, a processor and a storage medium. The method includes: sending, by a first network node, a load request message to a second network node, where the load request message is used for indicating configuration information used by the second network node in reporting load information to the first network node; and receiving, by the first network node, the load information reported by the second network node according to the configuration information. The second network node and the first network node belong to different logical nodes in a network. The technical problem that load management cannot be performed when the second network node and the first network node belong to different logical nodes in related technology is solved, and the maximum performance of the network is fully exhibited.

Abstract: Methods, apparatus, and systems for providing effective slice-level load metrics reporting and load balancing are disclosed. In one example aspect, a wireless communication method includes transmitting, by a first network element, a request to a second network element requesting resource status at a slice level of a slice. The slice represents a logical network of a physical network infrastructure. The method also includes receiving, by the first network element, load information at the slice level from the second network element in response to the request.

Abstract: Techniques are described to improve minimization of drive test (MDT) related measurements. For example, a wireless communication method is described for receiving, by a first device, a measurement configuration for minimization of drive test (MDT) related measurement, sending, by the first device to a third device, a measurement result based on a first measurement configuration, where the measurement result includes a time stamp and a type of measurement result. The wireless communication method also includes sending, by the first device to a second device, a second measurement configuration and the type of measurement result. The first measurement configuration, second measurement configuration, and the type of measurement result are based on the measurement configuration for MDT.

Abstract: A data transmission method includes: a communication node acquiring a layer 2 measurement value, and sending the layer 2 measurement value to a TCE. Another data transmission method includes: a DU acquiring a DU-side layer 2 measurement value, and sending the DU-side layer 2 measurement value to a CU or a TCE. Another data transmission method includes: a CU acquiring a DU-side layer 2 measurement value transmitted by a DU, and sending the DU-side layer 2 measurement value and a CU-side layer 2 measurement value to a TCE. Another data transmission method includes: a CU-UP acquiring a CU-UP-side layer 2 measurement value, and sending the CU-UP-side layer 2 measurement value to a CU-CP or a TCE. Another data transmission method includes: a CU-CP acquiring a CU-UP-side layer 2 measurement value transmitted by a CU-UP, and transmitting the CU-UP-side layer 2 measurement value to a TCE.
