Abstract: The present disclosure provides a method in a network node implementing a Service Communication Proxy, SCP, function. The method includes: receiving, from a first Network Function, NF, a request destined to a second NF, wherein the request comprises information on the second NF; redirecting the request to a third NF, wherein the redirected request comprises information on the third NF; and transmitting a response to the first NF, wherein the response comprises the information on the third NF.

Abstract: The present disclosure relates to the technical field of mineral powder processing, and provides a mineral powder pellet drying device, the device includes a drying box body and a material preparation trough, and shunting buffer assemblies are configured to withstand the impact of falling mineral powder pellets in an elastically concave mode and guide the mineral powder pellets to two sides for dispersion. The device in the present disclosure has a simple structure, and is capable of buffering the impact strength of the falling mineral powder pellets, so that the breakage of the mineral powder pellets caused by a fast falling speed is avoided, therefore, the device in the present disclosure has a better drying effect and is highly applicable.

Abstract: A phase-shifted full-bridge converter, and a method and a device for controlling the phase-shifted full-bridge converter are provided. The method includes: acquiring a current currently inputted to the phase-shifted full-bridge converter; determining, based on a correspondence between inputted currents and operation modes, an operation mode corresponding to the current currently inputted to the phase-shifted full-bridge converter; and acquiring, from maximum power point tracking in the determined operation mode, a phase angle for the phase-shifted full-bridge converter and a switching frequency of a switch transistor in the phase-shifted full-bridge converter, to control the switch transistor to operate based on the phase angle and the switching frequency.

Abstract: Methods and systems for transferring monitoring event information during a mobility procedure are provided. According to one aspect, a method for transferring monitoring event information during a mobility procedure comprises, at a first network node: receiving and storing subscription information indicating that a second network node has subscribed to get notification when there is a data delivery failure involving a User Equipment (UE), followed by the UE becoming reachable; detecting a data delivery failure involving the UE, and setting a flag to indicate that a data delivery failure involving the UE has occurred; receiving, from a third network node, a mobility related request; sending, to the third network node, a response to the mobility related request, comprising an indication that the third network node should notify the second network node when the UE becomes reachable and/or when then UE enters the IDLE state.

Abstract: In one aspect, an NRF is configured to inform an NF instance that has sent a discover request toward the NRF that the number of NF instances that match the search criteria used by the NRF in response to the discover request is greater than the number of NF instance profiles included in the NF instances array of the discover response.

Abstract: Exemplary embodiments include methods for establishing a user-requested protocol data unit (PDU) session in a user's visited public land mobile network (VPLMN), by a session management function (V-SMF) in the VPLMN. Such methods include receiving, from an access and mobility management function (AMF) in the VPLMN, a PDUSession_CreateSMContext Request to establish the PDU session to be routed through the user's home PLMN (HPLMN). The PDUSession_CreateSMContext Request identifies an SMF (H-SMF) in the user's HPLMN. Such methods include sending, to the identified H-SMF, a PDUSession_Create Request to create the PDU session. The PDUSession_Create Request includes an identifier of a session management (SM) context, in the V-SMF, that is associated with the PDU session. Such methods include receiving, from the H-SMF, a PDUSession_Update Request that includes an identifier of an SM context, in the H-SMF, that is associated with the PDU session. Embodiments also include complementary methods performed by the H-SMF.

Abstract: A method in a first Network Function (NF). The method includes: transmitting, to a second NF, a message containing a first binding indication associated with a context hosted by the first NF, the message or the first binding indication containing a parameter identifying a group of contexts.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for service handling. A method performed by at a first network entity comprises send a first request targeting resource context or session context to a second network entity. The method further comprises receive a first rejection response from the second network entity or an alternative second network entity. The first rejection response includes information comprising a first parameter indicating whether the first request should be retried with the second network entity or to any other alternative second network entity and/or a second parameter indicating whether to use the alternative second network entity for a subsequent request targeting the same resource context or session context, wherein the first rejection response including information comprising the second parameter is received from the alternative second network entity.

Abstract: A circulating fluidized bed apparatus, using fans, circulating pipes, functional branches and feeding pipes sequentially connected to form one or more circulating channels; the fans and jet streams generated thereby disperse materials into a fluidized state; the fluidized materials circulate and flow at a high speed in the circulating channels to achieve the objectives of the process, efficiently realizing operations such as drying, smashing, evaporating and distilling, concentrating, sieving, mixing, and ultraviolet sterilizing of powdered materials, realizing quick drying at normal temperature, and quickly preparing fresh plant materials into powdered materials at normal temperature. All the operations are performed by one apparatus, thus reducing equipment investment, simplifying production process steps, improving product quality, reducing production costs, and having low energy consumption, wide application and a simple structure.
