## Abstract

Provided are a method, device and apparatus for acquiring information, and a computer storage medium. In the method for acquiring information, a first node receives a message transmitted by a second node, where the message is related to a cell group of the second node, each cell group includes one or more cells, and each cell belongs to a same wideband carrier. The first node acquires information on a cell under the second node from the message, that is, information on a cell in the each cell group. A device and an apparatus for acquiring information, and a storage medium are further provided.

## Claims

### Claim 1

A method, comprising:
transmitting, by a secondary node (SN) 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, by the SN from the MN, a second message that includes (i) the 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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the SN transmits the first message in response to receiving a measurement report of a user equipment (UE) that includes the PCI.

### Claim 3

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.

### Claim 4 (depends on 3)

The method of claim 3, wherein the first message is transmitted by the SN in response to the SN receiving a measurement report of a user equipment (UE) that includes the PCI.

### Claim 5

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.

### Claim 6 (depends on 5)

The SN of claim 5, wherein the one or more processors are configured to initiate the transmitting of the first message in response to the SN receiving a measurement report of a user equipment (UE) that includes the PCI.

### Claim 7

A master node (MN) comprising:
one or more processors configured to implement steps of:
receiving, 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, responsive to the first message, information on the cell within the MN by searching for the CGI associated with the PCI; and
transmitting, 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.

### Claim 8 (depends on 7)

The MN of claim 7, wherein the first message is transmitted by the SN in response to the SN receiving a measurement report of a user equipment (UE) that includes the PCI.
