Description

A network slice deployment method and device

technical field

Embodiments of the present invention relate to the technical field of 5G, and in particular, to a network slice deployment method and device.

Background technique

With the continuous emergence of a variety of communication services, there are significant differences in the requirements of different communication services for network performance. The fifth-generation mobile communication (the 5th-generation, 5G) system introduces the concept of network slices. In order to cope with the difference in network performance requirements of different communication services.

Network slicing refers to customizing different logical networks according to different service requirements on physical or virtual network infrastructure. Network slicing is a combination of network function sets and resources required by a certain type of users or certain services. A network slice is a complete logical network that can provide communication services and has certain network capabilities. Network slicing may include a radio access network (radio access network, RAN) and a core network (core network, CN).

A network slice instance (NSI) is a logical network that actually operates and can meet certain network characteristics or service requirements. A complete network slice instance can provide complete end-to-end network services, and the network slice instance can include several network slice subnet instances (network slice subnet instance, NSSI) and/or several network functions (network function, NF).

In practical applications, there will be a scenario where a terminal device (such as a user equipment, UE) accesses a network slice. At this time, multiple network slices contain access and mobility management functions (access and mobility management function, AMF) It can be deployed independently, that is, it does not need to be shared, and it can also be shared and deployed. In practical applications, there will also be scenarios where one terminal device accesses multiple network slices. For example, in the Internet of Vehicles scenario, a vehicle terminal needs to be able to access eMBB network slices at the same time And uRLLC network slicing, access to eMBB network slicing is mainly for entertainment services that use large broadband, and access to uRLLC network slicing can provide services such as assisted automatic driving. At this time, the AMF contained in multiple network slices that the terminal device simultaneously accesses must share .

In the existing technology, 5G network slice deployment usually adopts manual configuration, that is, the staff specifies AMF and NRF (NF Repository Function, network registration function) in the network element configuration in NSSF (Network Slice Selection Function, network slice selection function), For example, AMF1 belongs to network slice 1 and AMF2 belongs to network slice 2. The terminal device stores the slice information supported by the contract when opening an account in UDM (Unified Data Management), such as signing up to support network slice 1 and support network slice 2, which means that the terminal device can use the services of network slice 1 and network slice 2; In the network registration process, the network side issues the network slice types that are allowed to be accessed to the terminal device according to its own capabilities and subscription information.

However, the deployment of network slicing in the existing technology needs to be manually specified, relying on personal experience in the slicing process, select AMF and NRF according to S-NSSAI and DNN (Data Network Name, data network name), AMF is based on DNN, S-NSSAI, SMF If UPF is selected as the service area ID, the optimal UPF and SMF cannot be determined, and the accuracy is poor and the efficiency is low.
