Abstract: This application provides a service processing method and apparatus of a service-based architecture. In the method, a service customer sends a service query request to a network element repository function entity NRF; the NRF receives the service query request, determines a service address of a service proxy that matches a service requested by the service query request, and sends the service address of the service proxy to the service customer; the service customer receives the service address of the service proxy that matches the service requested by the service query request; the service customer sends a service request to the service proxy corresponding to the service address, and establishes a service channel with the service proxy corresponding to the service address. No service function of a service provider needs to be optimized, so that impact on an original service of the service provider can be avoided to some extent.

Abstract: Embodiments of this application provide a network function service discovery method and a device. The method performed by an NRF includes: after establishing a communication connection to the NF, obtaining a digital certificate of the NF in a TLS or DTLS two-way authentication process, where the digital certificate of the NF carries a service name of the NF, a service name list on which the NF relies, and a service name list that relies on the NF; receiving a query request for querying an address of a target service that is sent by the NF, where the query request carries a complete domain name of the target service; and performing verification based on the service name of the target service and the digital certificate of the NF, and sending the address of the target service to the NF when the verification succeeds. Therefore, the NF services are discovered.

Abstract: A video transmission method is disclosed herein. A target video segmentation is transmitted to a piece of user equipment relatively quickly, so that caching efficiency of a caching device can be improved, and a processing burden of the caching device can be reduced. The method includes: receiving, by a gateway device, a target URL sent by a second user equipment, and determining, from a caching device, a second video corresponding to the target URL; determining a segmentation part of the target URL according to the segmentation part extraction model; and determining a target video segmentation from the second video according to the segmentation part of the target URL, and sending the target video segmentation to the second user equipment.
