- FIG. 3 is a schematic diagram of UE handover between different cells provided by the embodiment of the present application.
- the terminal device 301 is in the area covered by three different cells C1, C2, and C3. Assume that the terminal device 301 is currently accessing the cell C1.

- RRM Radio Resource Management
- the source base station sends a handover request to the target base station; the target base station performs admission control according to the received Quality of Service (QoS) information, and returns a handover confirmation message.

- the source cell corresponds to a source network device (such as a source base station), and the target cell corresponds to a target network device (such as a target base station).
- Handover execution UE immediately executes the handover process after receiving the handover command, that is, the UE disconnects the source cell and connects with the target cell (such as performing random access, sending a radio resource control (Radio Resource Control, RRC) handover completion message to The target base station, etc. can also include SN state transfer and data forwarding.
- RRC Radio Resource Control
- AMF Access and Mobility Management Function
- UPF User Plane Function
- Path Switch Network element path switch
- the UE needs to send a handover completion message to the target cell, so the UE needs to obtain corresponding uplink resources, so as to send a handover completion message to the target cell based on the uplink resources.
- the traditional handover process often includes a random access process, that is, after receiving the handover message, the terminal device, according to the relevant information of the target cell contained in the handover message (such as the physical cell identity of the target cell, Frequency information, random access resource information required for handover to the target cell, etc.), perform a random access procedure with the target cell, and then send a handover completion message to the target cell.

- Random access means that the terminal device starts to send a random access preamble index (preamble index) to the network device that is trying to access, until the connection between the terminal device and the network device is established. process.
- the random access procedure may occur in procedures such as handover and RRC re-establishment, for example.
- the random access involved in the embodiment of the present application may include four-step random access (also called a four-step random access channel, or simply called a 4-step RACH) and two-step random access (also called a four-step random access channel). It is a two-step random access channel, or can also be referred to as 2-step RACH for short).
- 4-step RACH random access channel
- 2-step RACH two-step random access channel
- Figure 4 is a schematic flow diagram of the 4-step RACH provided by the embodiment of the present application. As shown in Figure 4, the four-step random access process may specifically include:
- the terminal device sends a Msg1 to the network device.
- Msg1 is used to transmit a random access preamble, for example, a terminal device sends a random access preamble (or random access preamble sequence) index to a network device through a physical random access channel (physical random access channel, PRACH).
- a random access preamble or random access preamble sequence index
- PRACH physical random access channel
- the network device sends a Msg2 to the terminal device.
- Msg2 may include a random access response.
- the random access response may include a response timing advance (timing advance, TA), an uplink (UpLink, UL) grant (grant) and a temporary cell-radio network temporary identifier (C-RNTI) )Wait.
- timing advance timing advance
- UpLink uplink
- C-RNTI temporary cell-radio network temporary identifier
- the terminal device sends Msg3 to the network device.
- Msg3 is the first scheduled transmission in the random access process.
- the terminal device sends a message/data on the UL grant resources allocated by the network device based on the received random access response. For example, it sends an RRC establishment request message.
- the RRC The establishment request message may contain the identification information of the terminal device.
- the identification information may be, for example, the above-mentioned temporary C-RNTI.
- the network device sends Msg4 to the terminal device.
- Msg4 is used to indicate whether the terminal device has successfully connected to the network device. For example, after the network device receives the message/data sent by the terminal device on the allocated UL grant resources, if there is no conflict (or no competition), the network device sends a contention resolution message to the terminal device, for example, the network device sends RRC to the terminal device Create a message. Thereafter, the end device can communicate with the network device.

- a terminal device sends a random access preamble index (or called a random access preamble sequence) to a network device through a PRACH.
- the random access preamble index is allocated to the terminal device by the network device in advance. In other words, the random access preamble index is dedicated.
- the network device sends the MsgB to the terminal device.
- MsgB is used to indicate whether the terminal device has successfully connected to the network device.
- the network device sends a random access response to the terminal device.
- the random access response may include the corresponding TA, UL grant, etc.
- the UL grant may specifically include at least one of the following: time-frequency resources, modulation and coding scheme (MCS), new data indication (NDI), the moment when uplink transmission is initiated (such as subframe or time slot (slot)) and Uplink scheduling interval, etc.
- time-frequency resource included in the UL grant may specifically refer to the time-frequency position of the uplink resource scheduled by the UL grant.
- the uplink resources scheduled by the UL grant may be, for example, PUSCH resources.
- the UE can obtain uplink resources, thereby sending a handover completion message to the target cell, and by initiating the random access procedure, it can also obtain TA , to achieve synchronization with the target cell.
- the handover process can also be RACH-less HO, that is to say, the terminal device can perform handover without performing a random access process with the target cell process.
- the specific scenario currently introduced may be, for example, that the target cell can determine that the TA from the UE to the source cell is the same as the TA to the target cell, or that the TA from the UE to the target cell is 0.
