Information acquisition method, apparatus and device, and computer storage medium

A method, comprising:

• receiving, by a master node (MN) from a secondary node (SN), a first message that includes a physical cell identifier (PCI) of a cell, when a cell global identifier (CGI) of the cell associated with the PCI is not found in the SN;
• acquiring, by the MN, responsive to the first message, information on the cell within the MN by searching for the CGI associated with the PCI;
• and
• transmitting, by the MN to the SN, a second message that includes (i) information on the cell and (ii) the PCI of the cell, wherein the information on the cell within the MN includes a cell identifier, a public land mobile network (PLMN) list corresponding to the cell, a band list, a tracking area code (TAC), a radio access network (RAN) area code (RANAC), and frequency information.

A secondary node (SN) comprising:

• one or more processors configured to implement steps of:
• transmitting, to a master node (MN), a first message that includes a physical cell identifier (PCI) of a cell, when a cell global identifier (CGI) of the cell associated with the PCI is not found in the SN, to cause the MN to acquire information on the cell within the MN by searching for the CGI associated with the PCI;
• and
• receiving, from the MN, a second message that includes (i) information on the cell and (ii) the PCI of the cell, wherein the information on the cell within the MN includes a cell identifier, a public land mobile network (PLMN) list corresponding to the cell, a band list, a tracking area code (TAC), a radio access network (RAN) area code (RANAC), and frequency information.
