The invention discloses a method and a device for acquiring data, which are used to solve the problem of high overhead when an NF entity performs addressing in the process of acquiring data in the prior art. In the embodiment of the present invention, the NF entity sends a service request carrying the data indication identifier of the request number segment to the unified data management function entity; the NF entity receives the service response returned by the unified data management function entity that carries the user number segment of the unified data management function entity Afterwards, the corresponding relationship between the user number segment of the unified data management function entity and the address of the unified data management function entity is established. The NF entity of the present invention sends a service request, and carries the request number segment indication identifier, the unified data management function entity returns the service response, and returns the user number segment, and establishes the corresponding relationship between the user number segment and the address of the unified data management function entity, the present invention directly When sending a service request, the entity address of the unified data management function is not obtained through the NRF entity, which reduces the overhead.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for acquiring data. Background technique [0002] The 5G core network adopts a service-oriented architecture. The interface between each NF (Network Function) entity adopts SBI (Service Based Interface), and the communication mechanism of service invocation is adopted between NF entities. The NF entity performs service registration with the NRF entity, and classifies all services provided by itself. When the NF entity performs signaling addressing, it needs to consider the service discovery process. The NF entity can find a specific service to be called through the service discovery process provided by the NRF (Network Function Repository Function) entity. [0003] When finding a specific service that needs to be called during the service discovery process provided by the NRF entity, each user needs to query the NRF entity when add...
