Where client applications have different application service requirements, for example, video application slices typically require higher bandwidth and may suffer from slight packet loss; application slices for industrial control generally require ultra-low latency and are very tolerant of packet loss; XR application slices may require both ultra-low latency and ultra-large bandwidth.
S203, the newly added MEC application program identification information is added into the network slice description as single network slice selection auxiliary information and becomes an edge user service slice as a part of the network slice example.
Wherein, different application programs correspond to different network slice instance requirements, and MEC application program information needs to be considered when NSMF realizes the network slice instance.
The Single network slice selection assistance information (english: single-Network Slice Selection Assistance Information, S-nsai for short) may refer to a unique identification of a network slice.
S204, the MAS-MF forwards the information containing the edge user service slices to the OSS;
s205, the OSS sends the edge user service slice information to the MEO;
s206, the MEO selects a target MEC host according to the region information of the edge user, and deploys the edge user service slice instance into the target MEC host in the form of an application installation package so as to match the edge user with the edge user service slice.
The target MEC host may be selected by the MEO according to the input conditions of the edge user, for example, the edge user needs both low latency and high bandwidth service, and then the MEO selects the MEC host to satisfy two conditions, firstly, the target MEC host is closest to the user, and secondly, the target MEC host needs to satisfy the large bandwidth data transmission.
Wherein the MEO needs to have slice awareness capability, i.e. the capability to distinguish between different service slice requirements of the same edge user, in order to enable the corresponding edge user service slice to operate.
According to the method for generating the service slices of the edge users, which is provided by the embodiment of the application, the concept of the application slices can be provided according to the application type information of the edge users and different network performance requirements, and the service slices of the edge users are generated together with the network slices, so that the edge users can be ensured to purchase only one service slice, and the service slices simultaneously containing the application program slice instance and the network slice instance information can be triggered.
