Abstract

The embodiment of the invention discloses an indication method, a selection method and device of a public land mobile network. The method comprises: determining at least one PLMN supported by a current cell, the at least one PLMN comprising a first target PLMN, and a core network supported by each first target PLMN comprising a core network of a first protocol supporting mobile communication; generating system messages, wherein the system message comprises a first cell access related information field conforming to a first protocol and a second cell access related information field conformingto an existing second protocol of mobile communication; wherein the first cell access related information field carries a first PLMN list, and the first PLMN list comprises information related to a first target PLMN. According to the method provided by the invention, the network equipment determines how to indicate the PLMN supported by the cell to the terminal device under the condition that thePLMN supports the 5G core network or supports the 4G core network and the 5G core network at the same time, so that the requirements of a future communication system are met.

Description

technical field [0001] The present application relates to the field of communication technology, and more specifically relates to an indication method, selection method and equipment of a public land mobile network. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) Radio Access Network (Radio Access Network, RAN) defines two evolution directions of the 5G system, eLTE and 5G NR. In a 5G system, a cell can support multiple Public Land Mobile Networks (PLMNs), and a PLMN may support a 4G core network, a 5G core network, or both 4G and 5G core networks. The current communication protocol stipulates how the network device indicates to the terminal device the PLMN supported by the cell when the PLMN only supports the 4G core network, but when the PLMN supports the 5G core network or supports both 4G and 5G core networks, the network device cannot determine How to indicate the PLMN supported by the cell to the terminal...
