## Abstract

Provided are a method and device for transmitting a paging message, and a storage medium. The method includes: generating a paging message, and transmitting the paging message to a distributed network unit (DU), where the paging message includes assistance information, and the assistance information is used for instructing the DU to transmit the paging message.

## Claims

### Claim 1

A wireless communication method, comprising:
receiving, by a distributed unit (DU) of a base station in a 5G network from a centralized unit (CU) of the base station, a paging message, wherein the paging message comprises assistance information that comprises a discontinuous reception (DRX) parameter and a list of cells;
determining, by the DU, a transmission time point of the paging message according to the DRX parameter; and
transmitting, by the DU to a user equipment (UE), the paging message at the transmission time point according to the assistance information.

### Claim 2 (depends on 1)

The wireless communication method of claim 1, wherein transmitting the paging message according to the assistance information further comprises:
determining, by the DU, a transmission area of the paging message according to the list of cells; and
transmitting, by the DU to the UE, the paging message at the transmission area.

### Claim 3 (depends on 1)

The wireless communication method of claim 1, further comprising:
on a condition that the paging message is transmitted abnormally, transmitting, by the DU to the CU, a paging abnormal message, wherein the paging abnormal message comprises a reason for failing to transmitting the paging message.

### Claim 4 (depends on 3)

The wireless communication method of claim 3, wherein transmitting a paging abnormal message further comprises:
in response to determining that an abnormal event of missing a preset transmission time point occurs when transmitting the paging message, transmitting, by the DU to the CU, time advance information, wherein the time advance information is to instruct the CU to adjust a time point of transmitting the paging message.

### Claim 5 (depends on 1)

The wireless communication method of claim 1, wherein the paging message further comprises terminal paging record information.

### Claim 6

A wireless communication method, comprising:
generating, by a centralized unit (CU) of a base station in a 5G network, a paging message; and
transmitting, by the CU to a distributed unit (DU) of the base station, the paging message,
wherein the paging message comprises assistance information that comprises a discontinuous reception (DRX) parameter and a list of cells, and wherein the DRX parameter is configured for the DU to calculate a transmission time point for transmitting the paging message.

### Claim 7 (depends on 6)

The wireless communication method of claim 6, wherein transmitting the paging message further comprises:
placing, by the CU, the DRX parameter in the assistance information; and
transmitting, by the CU to the DU, the paging message carrying the assistance information.

### Claim 8 (depends on 6)

The wireless communication method of claim 6, wherein transmitting the paging message further comprises:
transmitting, by the CU to the DU, a DU synchronization message; receiving, by the CU, a response message transmitted by the DU according to the DU synchronization message;
calculating, by the CU, a transmission latency with the DU according to the response message; and
prior to the time point of transmitting the paging message, transmitting, by the CU to the DU, the paging message according to the transmission latency.

### Claim 9

A wireless communication device, comprising:
a reception module of a base station in a 5G network configured to receive, from a centralized unit (CU) of the base station, a paging message, wherein the paging message comprises assistance information that comprises a discontinuous reception (DRX) parameter and a list of cells; and
a transmission module of the base station configured to:
determine a transmission time point of the paging message according to the DRX parameter, and
transmit, to a user equipment (UE), the paging message at the transmission time point according to the assistance information.

### Claim 10 (depends on 9)

The wireless communication device of claim 9, wherein the transmission module is further configured to:
determine a transmission area of the paging message according to the list of cells; and
transmit, to the UE, the paging message at the transmission area.

### Claim 11 (depends on 9)

The wireless communication device of claim 9, wherein the transmission module is further configured to on a condition that the paging message is transmitted abnormally, transmit, to the CU, a paging abnormal message, wherein the paging abnormal message comprises a reason for failing to transmitting the paging message.

### Claim 12 (depends on 11)

The wireless communication device of claim 11, wherein the transmission module is further configured to:
in response to determining that an abnormal event of missing a preset transmission time point occurs when transmitting the paging message, transmit, to the CU, time advance information, wherein the time advance information is to instruct the CU to adjust a time point of transmitting the paging message.

### Claim 13 (depends on 9)

The wireless communication device of claim 9, wherein the paging message further comprises terminal paging record information.

### Claim 14

A wireless communication node, comprising:
a generation module of a base station in a 5G network configured to generate a paging message; and
a transmission module of the base station configured to transmit, to a distributed unit (DU) of the base station, the paging message,
wherein the paging message comprises assistance information that comprises a discontinuous reception (DRX) parameter and a list of cells, and wherein the DRX parameter is configured for the DU to calculate a transmission time point for transmitting the paging message.

### Claim 15 (depends on 14)

The wireless communication node of claim 14, wherein the transmission module is further configured to:
place the DRX parameter in the assistance information; and
transmit, to the DU, the paging message carrying the assistance information.

### Claim 16 (depends on 14)

The wireless communication node of claim 14, wherein the transmission module is further configured to:
transmit, to the DU, a DU synchronization message;
receive a response message transmitted by the DU according to the DU synchronization message;
calculate a transmission latency with the DU according to the response message; and
prior to the time point of transmitting the paging message, transmit, to the DU, the paging message according to the transmission latency.
