Step S503, the UE acquires the relevant information of the 2-step random access process according to the report information type configuration.

Step S504, the UE sends the relevant information of the 2-step random access process to the network equipment according to the configuration of the report mode.

Specifically, according to different configurations of the reporting means, this step may be implemented in any one of the following manners:

a first possible implementation: and periodically sending the related information of the 2-step random access process to the network equipment according to the reporting period in the reporting mode configuration.

A second possible implementation: and sending the related information of the 2-step random access process to the network equipment when receiving a report request sent by the network equipment.

Wherein the report request may be included in an RRC message or a system broadcast message.

A third possible implementation: and sending information related to the 2-step random access procedure to the network equipment when determining that at least one trigger condition in the reporting mode configuration is met.

Wherein the trigger condition may include at least one of: in the 2-step random access process, the retransmission times of the MSGA of the random access message are more than or equal to the maximum retransmission times of the MSGA; in the 2-step random access process, the retransmission times of the random access message MSGA are larger than or equal to a first preset threshold value; in the 2-step random access process, the retransmission times of the random access lead code are more than or equal to the maximum retransmission times of the random access lead code; in the 2-step random access process, the retransmission times of the random access lead code are more than or equal to a second preset threshold value; a random access feedback message MSGB of the 2-step random access process contains a Fallback Indication (Fallback Indication) of the network equipment; in a first preset time period, the retransmission times of the MSGA are greater than the maximum retransmission times of the MSGA; in a first preset time period, the retransmission times of the MSGA are larger than a third preset threshold value; in a second preset time period, in the 2-step random access process, the retransmission times of the random access lead code are greater than the maximum retransmission times of the random access lead code; in a second preset time period, in the 2-step random access process, the retransmission times of the random access lead code are larger than a fourth preset threshold value; and in a third preset time period, the number of times of back-off indication of the network equipment contained in the MSGB in the 2-step random access process is greater than or equal to a fifth preset threshold value.

In addition, according to an actual application scenario, when reporting information to the network device according to the trigger condition, the UE may adopt one or a combination of more of the trigger conditions, or may also adopt another trigger condition, or a combination of one or more other trigger conditions and the trigger condition, which is not limited in this embodiment.

Step S505, the network equipment receives the relevant information of the 2-step random access process which is configured and sent by the terminal equipment UE according to the report mode.

Specifically, one possible implementation manner of this step is: information related to the 2-step random access procedure is periodically received according to a reporting period in the reporting mode configuration.

Another possible implementation manner of this step is: and receiving the related information of the 2-step random access process sent by the UE when receiving the report request sent by the network equipment.

Step S507, the network device sends the configuration information of the optimized 2-step random access procedure to the UE.

In this embodiment, the step is an optional step, and after completing the optimization of the configuration information of the 2-step random access process, the network device may send the optimized configuration information of the 2-step random access process to the UE, so that the UE updates the configuration information of the 2-step random access process, and the success rate of the UE random access may be improved.

In another embodiment of this embodiment, the UE may also report information related to the 2-step random access procedure to the network device through the following embodiment, and this manner may be used alone, or may also be used in combination with one or more reporting manners in step S504 described above.

After the UE fails to access by adopting the 2-step random access process, when the UE accesses by adopting the 4-step random access process, the access failure information of the 2-step random access process is contained in a third message MSG3 of the 4-step random access process and is sent to the network equipment. Correspondingly, the network equipment receives MSG3 which is sent by the UE and contains access failure information of the 2-step random access process when the UE is accessed by adopting the 4-step random access process after the access failure of the 2-step random access process.

Specifically, the reason for access failure by adopting the 2-step random access procedure includes: the retransmission times of the random access message are more than or equal to the maximum retransmission times of the random access message; the retransmission times of the random access lead code are more than the maximum retransmission times of the random access lead code; the random access feedback message includes a back-off indication of the network device.

And after the UE fails to access due to any reason when the UE accesses by adopting the 2-step random access process, when the UE accesses by adopting the 4-step random access process, the access failure information of the 2-step random access process is contained in the MSG3 and is sent to the network equipment. Correspondingly, after the access fails due to any reason when the UE performs the access by adopting the 2-step random access process, the network equipment receives MSG3 which is sent by adopting the 4-step random access process and contains the access failure information of the 2-step random access process.

Further, the network device may optimize the configuration information of the 2-step random access procedure according to the received MSG3 that includes the access failure information of the 2-step random access procedure.

In this embodiment, the UE may be configured to continuously start a function of reporting the 2-step random access procedure related information to the network device.

In another implementation manner of this embodiment, the method may further include: the network equipment sends 2-step-random access process related information reporting instructions to the UE, and the UE receives the 2-step-random access process related information reporting instructions.

It should be noted that the network device may send the 2-step random access procedure related information reporting instruction to the UE before step S501, or the network device may also send the 2-step random access procedure related information reporting instruction, the report information type configuration, and the report mode configuration to the UE. Accordingly, the UE may receive a 2-step random access procedure related information reporting indication and report information type configuration and reporting mode configuration sent together by the network device.

In this embodiment, the network device may send a 2-step-random access procedure related information reporting instruction to the UE when needed, and when receiving the 2-step-random access procedure related information reporting instruction, the UE starts a function of reporting the 2-step-random access procedure related information to the network device, and may execute the above steps S501 to S507.

Optionally, the network device may further send a 2-step random access procedure related information report stop instruction to the UE, and after receiving the 2-step random access procedure related information report stop instruction, the UE closes the function of reporting the 2-step random access procedure related information to the network device. In the embodiment of the application, the network equipment sends the report information type configuration and the report mode configuration to the UE, the report information type configuration and the report mode configuration of the 2-step random access process relevant information reported by the UE to the UE are pre-configured, and the UE acquires the 2-step random access process relevant information according to the report information type configuration; according to the report mode configuration, sending the related information of the 2-step random access process to the network equipment; the network equipment receives the relevant information of the 2-step random access process which is configured and sent by the UE according to the report mode, thereby realizing the automatic collection and report of the relevant information of the 2-step random access process, meeting the requirements of operators on the automatic collection and automatic maintenance of network optimization, and improving the success rate of the 2-step random access.
