Access control method, access network node and core network node

Abstract

The invention provides an access control method, an access network node and a core network node, and relates to the technical field of communication. The access control method is applied to an access network node, and comprises the following steps: sending related information of a first cell to a core network node; wherein the related information of the first cell is used for the core network node to perform access control of the terminal; the related information of the first cell comprises first indication information that the first cell supports access of at least one network type; or the related information of the first cell comprises the information of the first cell corresponding to the network type access tendency of the terminal. According to the scheme, the condition of terminal access failure can be avoided, so that the reliability of terminal access is ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access control method, an access network node and a core network node. Background technique [0002] In R16, the radio access network (RAN, also called access network node) side is not responsible for judging whether a user equipment (User Equipment, UE, referred to as terminal) can access a certain cell, but the core network judges whether the UE passes through a certain cell. The legality of community access to the network. When the UE requests to access the network through a non-public network (NPN) cell, the RAN will provide the core network node with the NPN information supported by the cell, and the core network will provide the NPN information supported by the cell based on the RAN and the UE's The subscription information determines whether the UE can access the network through the cell. [0003] In R17, if there is a public land mobile network (Public...

Problems solved by technology

[0004] Embodiments of the present invention provide an access control method, an access network node, and a core network node, which can solve the problem that the network side may misjudge an access network node that can be accessed when the PLMN is shared with the PNI-NPN or the PLMN is shared with the SNPN and the PNI-NPN. The UE that enters the network cannot access the network, resulting in the problem of UE access failure
