Methods and apparatuses for network function service discovery. A method at a network function (NF) service consumer comprises sending a service request to a service discovery entity. The method further comprises receiving a service response from the service discovery entity. The service request includes a parameter indicating a client type that one or more candidate target NFs can serve.

Method and apparatus for network function service discovery

The present disclosure proposes a proxy method, comprising receiving a request for a service in a first architecture from a requester network function (NF) in a second architecture, obtaining a response of the service from a serving NF on behalf of the requester NF, and sending a further response to the requester NF based on the response of the service. The proxy method may be implemented on a NF or a function entity within a NF.

Method and device for proxy between different architectures

In a first aspect of the disclosure, a method performed by an Application Server (AS) of registering a non-Subscriber Identity Module (SIM) mobile terminal with a wireless network is provided. The method comprises receiving a request for registration of the non-SIM mobile terminal, the non-SIM mobile terminal being associated with a trusted SIM mobile terminal by means of an identifier of the non-SIM mobile terminal, issuing a virtual International Mobile Station Equipment Identity (vIMEI) for the non-SIM mobile terminal, providing an Equipment Identity Register (EIR), with the vIMEI, providing a certificate issuing entity in the network with the vIMEI, receiving, from the certificate issuing entity, a certificate issued based on the vIMEI, and providing the non-SIM mobile terminal with the issued certificate.

Methods and devices of registering, verifying identity of, and invalidating non-SIM mobile terminals accessing a wireless communication network

An apparatus for producing ethylene includes: a reactor; a first separation column, connected to the reactor; a second separation column, the upper part of the second separation column being connected to the bottom of the first separation column, and the top of the second separation column being connected to the lower part of the first separation column; a first condenser, an inlet of the first condenser being connected to the top of the first separation column, and an outlet of the first condenser being connected to the upper part of the first separation column; and a third separation column, used for receiving a second part of a first condensate from the condenser and separating the received part. A method for producing ethylene using the aforementioned apparatus is also described.
