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.

Systems and methods for MME adaptive selection are described. The method includes: initializing a health checkup algorithm at an eNodeB for each MME connected to as per configuration values; starting a health check timer for each MME; continuing with an Initial Attach procedure for incoming calls based on SAE-Temporary Mobile Subscriber Id (S-TMSI), (Globally Unique MME Identifier) GUMMEI, or capacity/load balancing considerations; on every UE attach attempt, incrementing a total calls count; and on every S1 AP Error Indication/no response from an ME, incrementing a total fail calls count; determining when the health check timer for an MME expires; calculating a failed calls/total calls percentage value. Based on the value of the timer, appropriate action is taken.

Methods and apparatus for user transfer in a Cloud-radio access network (C-RAN) are disclosed.

Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.
