## Abstract

An early identification method is performed by a base station, and includes: determining a preset mode for terminal type information; and receiving the terminal type information sent by a terminal, wherein the terminal type information is used for early identification of the terminal.

## Claims

### Claim 1

An early identification method, performed by a base station, comprising:
determining a preset mode for terminal type information; and
receiving the terminal type information sent by a terminal, wherein the terminal type information is used for early identification of the terminal.

### Claim 2 (depends on 1)

The method of claim 1, wherein the terminal is one or more of:
a reduced capability (Redcap) terminal; or
a preset version of a new radio (NR) terminal.

### Claim 3 (depends on 1)

The method of claim 1, wherein the preset mode is one or more of:
a first mode of receiving the terminal type information sent by the terminal through a first random access message (msg1) in a four-step random access procedure;
a second mode of receiving the terminal type information sent by the terminal through a third random access message (msg3) in a four-step random access procedure;
a third mode of receiving the terminal type information sent by the terminal through a random access message (msgA) of a physical random access channel (PRACH) in a two-step random access procedure;
a fourth mode of receiving the terminal type information sent by the terminal through a random access message (msgA) of a physical uplink shared channel (PUSCH) in a two-step random access procedure; or
a fifth mode of receiving the terminal type information sent by the terminal through a fifth message (msg5) in a random access procedure.

### Claim 4 (depends on 3)

The method of claim 3,
wherein at least one of the msg1 or the msgA of the PRACH in the two-step random access procedure is configured to indicate a preset random access resource;
wherein the preset random access resource is configured by the base station.

### Claim 5 (depends on 1)

The method of claim 1, further comprising:
determining that the terminal is a terminal that needs to be identified early; and
sending a notification message to a core network device, wherein the notification message is configured to notify that the terminal is the terminal that needs to be identified early.

### Claim 6

An early identification method, performed by a terminal, comprising:
sending terminal type information to a base station based on a preset mode determined by the base station, wherein the terminal type information is used for early identification of the terminal.

### Claim 7 (depends on 6)

The method of claim 6, wherein the terminal is one or more of:
a reduced capability (Redcap) terminal; or
a preset version of a new radio (NR) terminal.

### Claim 8 (depends on 6)

The method of claim 6, wherein the preset mode is one or more of:
a first mode of sending by the terminal the terminal type information to the base station through a first random access message (msg1) in a four-step random access procedure;
a second mode of sending by the terminal the terminal type information to the base station through a third random access message (msg3) in a four-step random access procedure;
a third mode of sending by the terminal the terminal type information to the base station through a random access message (msgA) of a physical random access channel (PRACH) in a two-step random access procedure;
a fourth mode of sending by the terminal the terminal type information to the base station through a random access message (msgA) of a physical uplink shared channel (PUSCH) in a two-step random access procedure; or
a fifth mode of sending by the terminal the terminal type information to the base station through a fifth message (msg5) in a random access procedure.

### Claim 9 (depends on 6)

The method of claim 6,
wherein at least one of the msg1 or the msgA of the PRACH in the two-step random access procedure is configured to indicate a preset random access resource;
wherein the preset random access resource is configured by the base station.

### Claim 10

(canceled)

### Claim 11

(canceled)

### Claim 12

A base station, comprising:
a memory storing computer-executable instructions; and
a processor, coupled to the memory, wherein the processor is configured to:
determine a preset mode for terminal type information; and
receive the terminal type information sent by a terminal, wherein the terminal type information is used for early identification of the terminal.

### Claim 13 (depends on 1)

A non-transitory computer storage medium having computer-executable instructions stored thereon, wherein when the computer-executable instructions are executed by a processor, the processor is caused to perform the method of claim 1.

### Claim 14 (depends on 12)

The communication device of claim 12, wherein the terminal is one or more of:
a reduced capability (Redcap) terminal; or
a preset version of a new radio (NR) terminal.

### Claim 15 (depends on 12)

The communication device of claim 12, wherein the preset mode is one or more of:
a first mode of receiving the terminal type information sent by the terminal through a first random access message (msg1) in a four-step random access procedure;
a second mode of receiving the terminal type information sent by the terminal through a third random access message (msg3) in a four-step random access procedure;
a third mode of receiving the terminal type information sent by the terminal through a random access message (msgA) of a physical random access channel (PRACH) in a two-step random access procedure;
a fourth mode of receiving the terminal type information sent by the terminal through a random access message (msgA) of a physical uplink shared channel (PUSCH) in a two-step random access procedure; or
a fifth mode of receiving the terminal type information sent by the terminal through a fifth message (msg5) in a random access procedure.

### Claim 16 (depends on 15)

The communication device of claim 15,
wherein at least one of the msg1 or the msgA of the PRACH in the two-step random access procedure is configured to indicate a preset random access resource;
wherein the preset random access resource is configured by the base station.

### Claim 17 (depends on 12)

The communication device of claim 12, wherein the processor is further configured to:
determine that the terminal is a terminal that needs to be identified early; and
send a notification message to a core network device, wherein the notification message is configured to notify that the terminal is the terminal that needs to be identified early.

### Claim 18 (depends on 6)

A terminal, comprising:
a memory storing computer-executable instructions; and
