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.
At present, a large number of terminals which do not support the 2-step RACH function exist, and before UE reports the terminal capability level, a base station cannot know whether the terminal supports 2-step access, so that the base station configures 2-step RACH cells for each access terminal, and the 2-step RACH cells configured in SIB1 have no effect on the terminals.
For example, after the terminal R16 is on the market, many R15 terminals that do not support 2-step access are still in use, and it is not necessary to configure the cell for 2-step access for the terminal that does not support 2-step access, and the number of Radio Bearers (RBs) occupied by SIB1 transmission is increased.
In order to reduce the cell overhead of SIB1, the present invention configures the cell only for the terminals of R16 that support 2-step access.
In a 5G system, a terminal device may be referred to as a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, e.g., a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs).

Fig. 1 is a schematic flowchart of a cell configuration method provided by the present invention, and as shown in fig. 1, the cell configuration method is applied to a network side device, and includes, but is not limited to, the following steps:
first, in step S11, a terminal capability level of a target terminal is acquired based on random access of the target terminal.
The network side device related to the embodiment of the present invention may be a base station, and the base station may include a plurality of cells for providing services for the terminal. The terminal may include a User Equipment (UE) supporting an R16 protocol.
The base station informs the UE of an available Random Access Preamble (Random Access Preamble) in advance through system broadcast in an initial Access scenario or through an RRC message in an HO or SN Addition scenario, and the UE selects one of the Random Access preambles as its own temporary identifier and sends a Random Access request (Random Access Preamble) to the base station.
For the base station, after the target terminal performs random access, the target terminal does not configure the target cell in the SIB1, but reports the terminal capability level to the base station before Radio Resource Control (RRC) Reconfiguration.

Subsequently, in step S13, the RRC reconfiguration message is sent to the target terminal, so that the target terminal parses the RRC reconfiguration message to store the configuration information in a target storage area.
The base station sends an RRC reconfiguration message configured with the target cell to the target terminal, the target terminal analyzes a 2-step RACH cell from the RRC reconfiguration message, reads 2-step RACH configuration information from the 2-step RACH cell, and stores the 2-step RACH configuration information into a target storage area. The target storage area may be partitioned in the memory for the target terminal.
The target terminal performs 2-step RACH configuration using the configuration information.
And the target terminal initiates random access in a mode of selecting 2-step RACH based on the 2-step RACH configuration information in the subsequent random access of the cell.
The cell configuration method provided by the invention utilizes RRC to configure cells for the terminal equipment with 2-step access capability, thereby reducing the cost of public resources such as SIB1 cells and the like and improving the utilization rate of cell spectrum.
Optionally, the configuring, according to the terminal capability level, a target information element of the target terminal in an RRC reconfiguration message includes:
configuring the target cell in an RRC reconfiguration message under the condition that the terminal capability level of the target terminal supports target cell configuration; the target cell is a 2-step RACH cell.
When the UE accesses the network for the first time, RRC connection is needed, and if the UE needs to transmit an IP packet, a DRB or SRB2 bearer is established through RRC connection reconfiguration; the base station initiates an RRC reconfiguration message to the UE, the UE performs configuration according to the RRC reconfiguration protocol message after receiving the RRC reconfiguration message, and the UE initiates a connection reconfiguration success signaling to the base station.
If the terminal capability level of the target terminal supports 2-Step RACH, for example, two Step RACH-r16 in the terminal capability level is "supported", the base station configures resource information of the 2-Step RACH to the target terminal, that is, adds a 2-Step RACH cell to an RRC reconfiguration message, and the target cell is used for carrying configuration information for configuring the 2-Step RACH to the target terminal.
