Network slice matching method and device

Abstract

The present invention provides a network slice matching method and device. The method includes: when receiving a service to be run, determining the priority of each URSP rule acquired in advance, and according to the priority order of each URSP rule from high to low, Match each URSP rule with the service to be run in turn. If the URSP rule currently used for matching matches the service to be run, and determine that the network slice in the URSP rule is an unavailable slice, and the limited connection in the URSP rule When the access identifier is the first identifier, that is, the limited access identifier in the URSP rule indicates that the service to be run is specified to be carried by the network slice in the URSP rule, the matching process with the service to be run is completed, and the bearer of the service to be run is refused . Applying the network slicing matching method provided by the present invention realizes that specified services are rejected and fall back to lower priority slicing or default slicing bearer.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a network slice matching method and device. Background technique [0002] With the development of communication technology, the concept of network slicing has been introduced into the 5G network architecture. Network slicing is mainly to create multiple independent dedicated virtual sub-networks in the same infrastructure to meet the needs of different services. To access network slicing, terminals need to sign up for network slicing in UDM (Unified Data Management, unified data management) in advance, and at the same time determine URSP (UE Routing Selection Policy, UE routing selection policy) in PCF (Policy Control Function, policy control function) in advance select strategy). [0003] In the prior art, according to each URSP rule in the URSP issued by the PCF, the terminal matches the corresponding network slice for each service to be run according to the order o...

Problems solved by technology

[0003] In the prior art, according to each URSP rule in the URSP issued by the PCF, the terminal matches the corresponding network slice for each service to be run according to the order of priority. If the currently matched network slice is not available, it will fall back to the low priority The application of existing technologies cannot solve the problem of refusal of specified services to fall back to lower-priority network slices or default slices.
