Cell access method, device and terminal

Abstract

The invention provides a cell access method, a cell access device and a terminal. The method comprises the following steps: acquiring a master information block MIB message sent by a target cell of anew air interface NR system; when the terminal is an independent networking SA terminal, if the cell prohibition parameter record in the MIB message is non-prohibition indication information, determining that the target cell is non-prohibition access; when the terminal is a non-independent networking NSA terminal, if the cell prohibition parameter record in the MIB message is non-prohibition indication information, determining that the target cell is prohibited from accessing. By adopting the method, when the system message cell parameter of the target cell is indicated to be non-prohibited, the NSA terminal and the SA terminal judge the cell parameter differently. By means of the mode, the NSA terminal and the SA terminal can have access to the same 5G cell at the same time, and the purposes that NSA resides in an anchor point LTE cell and SA resides in an NR cell are achieved.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a cell access method, device and terminal. Background technique [0002] In 5G current network applications, 5G cells are required to support non-standalone (Non-Stand Alone, NSA) and stand-alone (Stand Alone, SA) dual-mode terminals to simultaneously access and initiate data services. Evolution (Long Term Evolution, LTE) system messages, public land mobile network (Public Land Mobile Network, PLMN) selection, cell selection to achieve camping in the NSA anchor LTE cell, the SA terminal searches for the new air interface (New Radio, NR) of the NSA The system cell, PLMN selection, and cell selection realize camping in the NR cell. [0003] In the existing communication protocol, the cell barred field in the master information block (Master Information Block, MIB) message of the system message represents the cell barred parameter. If the terminal reads barred as barred, ...

Problems solved by technology

[0006] The purpose of the technical solution of the present invention is to provide a cell access method, device, and terminal, which are used to solve the problem that the conventional technology cannot realize that the NSA terminal and the SA terminal can access the same 5G cell at the same time under the configuration of the system message cellBarred, and realize that the NSA terminal resides in the same 5G cell. The problem of staying in the anchor LTE cell and the SA terminal staying in the NR cell
