Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information processing method, an information processing apparatus, information processing equipment, and a computer-readable storage medium.
Background
With the wide application of wireless communication, spectrum resources become more and more intense, and scenes of competing for using spectrum are more and more. In the mechanism of competing spectrum usage, LBT (Listen Before Talk) method is usually adopted. LBT is a channel access mechanism that enables efficient sharing of the same spectrum resources among wlans.
In the LBT method, a station that wants to transmit data first listens to the medium for carriers to determine whether another station is transmitting data. If the medium is idle, the station can transmit data; otherwise, the station will avoid for a period of time before attempting.
If LBT technology is used to access the random channel in the shared band, the time for completing the contention random access procedure is significantly increased, which will seriously affect the capacity and delay of channel access. Currently, the Access procedure time can be reduced by using a 2-step RACH (Random Access Channel).
When the LBT monitors that the channel is idle, a 2-step RACH may be adopted as initial access, a first message msgA is used to identify a UE (User Equipment), and a second message msgB is used for collision resolution. The first message in a 2-step RACH is a preamble-like signal and payload, while the second message is for Contention Based Random Access (CBRA) occupancy resolution with a possible payload.
In contention use spectrum, 2-step RACH access is employed, which supports fall back to 4-step RACH in case of multiple failures such as 2-step RACH. For example, if the gNB (NR Node B, NR Node) detects a preamble in msg1 instead of a payload. The 2-step RACH may fall back to the 4-step RACH if the UE does not get a response to the first message within a given time or the gNB sends a second message of a different type.
As can be seen from the above, in the prior art, although the network access based on LBT is clear, information in the access process is not considered, which is not favorable for resource allocation and network optimization.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided by an embodiment of the present invention, and is applied to a terminal, as shown in fig. 1, including the following steps:
the number of attempts to use 2-step RACH; number of attempts with 4-step RACH.
When the LBT monitors that the channel is idle under the condition that the terminal is not connected to any base station, the terminal starts a 2-stepRACH process and sends msgA to the base station. At this time, the number of attempts to use the 2-step RACH is counted. And calculating the total number of times of transmitting msgA until the terminal successfully accesses the network, namely the number of attempts of adopting 2-step RACH, which need to be reported by the terminal.
Fallback to 4-step RACH is supported in case of multiple failures of 2-step RACH. The terminal sends an msg1 to the base station, i.e., a 4-step RACH attempt. At this point, the number of attempts to use the 4-step RACH is counted. The total number of msg1 transmissions, i.e. the number of attempts by the terminal to use 4-steplach that the terminal needs to report, is counted until the terminal successfully accesses the network.
In addition, to further facilitate network optimization, in case that the terminal accesses to the network by using LBT, the RACH information may further include: the number of times the LBT listens to the channel as idle.
The terminal monitors whether the carrier exists on the medium by using the LBT so as to determine whether other stations transmit data. If the channel is idle, the station can transmit data. After the terminal is successfully accessed to the network, one or more information can be selected and reported according to the requirements and the actual conditions of the network side equipment. And after receiving the RACH information reported by the terminal, the network side equipment carries out statistical analysis on the RACH information. For example, if it is found that some terminals fail to connect normally by using 2-step RACH or 4-step RACH, a message may be sent to instruct the terminals to abandon the random access scheme with a low success probability.
In the embodiment of the invention, the terminal reports the RACH information to the network side equipment under the condition of successfully accessing the network, so as to provide information for network optimization, thereby being beneficial to resource allocation and network optimization.
The terminal can report the RACH information in the following modes:
(1) and the terminal reports the RACH information to the network side equipment according to the indication of the network side equipment.
In this step, the terminal receives a user information request message sent by the network side device, where the user information request message includes a random access report request. Then, the terminal sends a user information response message to the network side device according to the random access report request, wherein the user information response message comprises the RACH information.
For example, after the terminal accesses the network, the base station adds a random access report request to a user Information request message (UE Information request message) to request the terminal to report RACH Information. After receiving the user Information request message, the terminal reports the RACH Information through a user Information Response message (UE Information Response message).
(2) And the terminal sends RLF (Radio link failure information) report information to the network side equipment, wherein the RLF report information comprises the RACH information.
Specifically, after RRC (Radio Resource Control) connection reestablishment is completed, the base station may send a user information request message to the terminal. After receiving the user information response message, the terminal returns the user information response message to the base station, and the RACH information can be reported in the RLF.
(3) And the terminal sends RRC connection establishment failure information to the network side equipment, wherein the RRC connection establishment failure information comprises the RACH information.
For example, after the RRC connection establishment fails, the terminal may report the RACH information and the RRC connection establishment failure information to the base station together.
(4) And the terminal actively reports the RACH information.
After the terminal successfully accesses to the network, the terminal can actively report the RACH information. For example, the terminal sends an Indication (Indication) message to the base station to inform the base station that RACH information needs to be reported. The terminal actively reports the RACH information, so that the information can be reported more timely.
Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided by an embodiment of the present invention, and is applied to a network side device, as shown in fig. 2, including the following steps:
wherein the RACH information comprises at least one of the following information: the number of attempts to use 2-step RACH; number of attempts with 4-step RACH.
In addition, to further facilitate network optimization, if the terminal utilizes LBT to access the network, the RACH information may further include: the number of times the LBT listens to the channel as idle.
In the embodiment of the invention, the terminal reports the RACH information to the network side equipment under the condition of successfully accessing the network, so as to provide information for network optimization, thereby being beneficial to resource allocation and network optimization.
The network side equipment can receive the RACH information reported by the terminal in the following modes:
(1) and then, the network side equipment receives a user information response message sent by the terminal according to the random access report request, and the user information response message comprises the RACH information.
(2) And the network side equipment receives RLF report information sent by the terminal, wherein the RLF report information comprises the RACH information.
(3) And the network side equipment receives RRC connection establishment failure information sent by the terminal, wherein the RRC connection establishment failure information comprises the RACH information.
And after receiving the RACH information reported by the terminal, the network side equipment carries out statistical analysis on the RACH information. For example, if it is found that some terminals fail to connect normally by using 2-step RACH or 4-step RACH, a message may be sent to instruct the terminals to abandon the random access scheme with a low success probability.
Although the prior art has clarified the channel access based on LBT, how the terminal reports the previous access information after successfully utilizing LBT to access the channel is not involved. After the terminal is accessed, the embodiment of the invention reports the previously accessed RACH information to network side equipment (such as a base station) and provides an information reporting scene, thereby providing optimization for subsequent access, reducing access time and improving access success rate.
