Problems solved by technology

The security of the current URSP rules is not strong. Once the URSP rules are tampered with, unauthorized applications can illegally use slice services. For example, during the registration process of 5G slices, the terminal side will report slice policy information to the network, including The application ID of the slicing service and its corresponding traffic routing policy. Unauthorized applications may steal the ID of the authorized application and use the slicing service.

Abstract

The invention provides a slice routing rule tamper-proofing method, a terminal, a network element and a medium. The method comprises the following steps: defining a description identifier used for describing an application identifier in a slice routing rule; establishing a relation mapping table between the description identifier of each application program and the respective application identifier of each application program; receiving a routing rule and a slice identification rule returned by the core network; judging whether the first application identifier and a description identifier mapped by the first application identifier exist in the relation mapping table or not; if the first application identifier and the description identifier mapped by the first application identifier exist, matching the corresponding first application program with the routing rule and the slice identifier rule based on the first application identifier and the description identifier mapped by the first application identifier. According to the embodiment of the invention, at least the security of the URSP rule can be effectively improved, and an unauthorized application program is prevented from illegally using the slicing service.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to an anti-tampering method for slice routing rules, a terminal, a network slice management functional network element, a user plane functional network element, and a computer-readable storage medium. Background technique [0002] Network slicing technology is one of the key technologies of 5G (5th generation mobile networks, fifth-generation mobile communication technology). It can configure the network to enable users to obtain the most suitable network services on demand and increase the flexibility of network resources. [0003] In the R15 stage of the 3rd generation partnership project (3GPP), the 5G core network already has some policy configuration solutions for users and services, and defines the user equipment routing selection policy (URSP) The rules focus on defining service-level configuration and management strategies, and provide flexible configu...
