Background
In the 5G System, after some types of System Information (SI) need to be sent by the UE, the network side broadcasts the System Information. Such a request for system information may be sent in different states (e.g., IDLE, INACTIVE, CONNECTED). After receiving the request message of the UE, the network side may send the requested system information to the terminal device (UE) in a broadcast manner, or send the requested system information to the UE in a unicast manner (e.g., through a dedicated RRC signaling of the connected UE).
In addition, when providing the reference time for the UE, the network side may send a system message (e.g., SIB 16) to the UE, where the system message may indicate the reference time amount (e.g., treference), including:

In the technical solution provided in the embodiment of the present invention, in a mobility process of a terminal device, a target network node receives indication information sent by a source network node, where the indication information indicates that the terminal device needs to acquire system-related information, and after receiving the indication information, the target network node transmits the system-related information that the terminal device needs to acquire to the source network node, so that the source network node transmits to the terminal device, thereby enabling a network side to send the system information to the terminal device in the mobility process, and enabling the terminal device to receive the system information of a target cell in time.
Fig. 2 is a flowchart of another system information transmission method according to an embodiment of the present invention, where the method 200 is applied to a source network node in a UE mobility process. In other words, the method 200 may be performed by software or hardware installed on the source network node. As shown in fig. 2, the method may include the following steps.
S210, sending indication information to a target network node, wherein the indication information indicates that the UE needs to acquire system-related information.
In the embodiment of the present invention, after the UE reports the request to acquire the system-related information, and may enter the mobility process, the source network node sends the indication information to the target network node, so that the UE in the mobility process can acquire the system-related information of the target cell in time.
In one possible implementation, in order to save signaling overhead, the source network node may send the indication information to the target network node in a request message carried in a mobility procedure of the UE. Thus, in this possible implementation, S210 may include: and carrying the indication information in a request message in the mobility process and sending the request message to the target network node.
For example, if the mobility procedure in which the UE is currently located is a cell handover procedure, the request message may be a handover request message in the cell handover procedure; if the mobility process of the UE is a Secondary Cell Group (SCG) change process, the request message can be a Secondary Node (SN) change request message in the SCG change process; the request message may be a SN addition request message in an SCG addition procedure if the mobility procedure in which the UE is currently located is the SCG addition procedure.
S212, receiving the system-related information that needs to be obtained by the terminal device and returned by the target network node.
In a possible implementation manner, the target network node may carry the system-related information that the UE needs to acquire in the confirmation message in the mobility process to transmit to the source network node, so as to save signaling overhead. Thus, in this possible implementation, S212 may include: and receiving a confirmation message sent by the target network node in the mobility process, wherein the confirmation message carries system-related information required to be acquired by the UE.
For example, if the mobility procedure in which the UE is currently located is a cell handover procedure, the acknowledgment message may be a handover request acknowledgment message in the cell handover procedure; if the mobility process in which the UE is currently located is a Secondary Cell Group (SCG) change process, the confirmation message may be an SN change request confirmation message in the SCG change process; the confirmation message may be an SN addition request confirmation message in the SCG addition procedure if the mobility procedure in which the UE is currently located is the SCG addition procedure.
S214, transmitting the system related information to the terminal equipment.
In one possible implementation, in order to save signaling overhead, the source network node may send the UE the system-related information carried in a mobility indication message in the mobility procedure. Thus, in this possible implementation, S214 may include: and carrying the system related information in a mobile indication message of the mobility process and sending the mobile indication message to the terminal equipment.
For example, if the mobility procedure currently initiated by the UE is a cell handover procedure, the mobility indication message may be a handover message in the cell handover procedure, for example, a Radio Resource Control (RRC) synchronization configuration message, for example, a redirection setup within an RRC configuration message. If the mobility process initiated by the UE currently is a Secondary Cell Group (SCG) change process, the mobility indication message can be an SN change message in the SCG change process; the mobility indication message may be a SN addition request message in an SCG addition procedure if the mobility procedure in which the UE is currently located is the SCG addition procedure.
The indication information sent by the source network node in S210 may adopt various possible implementation manners of the indication information received by the target network node in the method 100, which is not described herein again.
The system-related information received by the source network node in S212 may adopt various possible implementation manners of the system-related information sent by the target network node in the method 100, which are not described herein again.
In the technical scheme provided by the embodiment of the invention, in the mobility process of the terminal equipment, the source network node receives and sends the indication information to the target network node, the indication information indicates that the terminal equipment needs to acquire the system related information, and the source network node transmits the system related information returned by the target network node to the terminal equipment after receiving the system related information, so that the network side can send the system information to the terminal equipment in the mobility process, and the terminal equipment can receive the system information of the target cell in time.
Fig. 3 is a flowchart illustrating a method for transmitting system information according to an embodiment of the present invention, where the method 300 is applied to a UE. In other words, the method may be performed by software or hardware installed on the UE. As shown in fig. 3, the method may include the following steps.
S310, in the mobility process, receiving system related information from the network side.
The system-related information is the same as the system-related information in the method 100 and the method 200, and various possible implementation manners of the system-related information in the method 100 and the method 200 may be adopted, which are not described herein again.
In one possible implementation, after receiving the system-related information sent by the network side, the method may further include: if the system-related information comprises reference time information, after downlink synchronization with a target cell is performed, according to the synchronization information of the target cell, applying the reference time information corresponding to the synchronization information in the system-related information, and sending the corresponding reference time information to a high layer. That is, after the UE is handed over to the target cell and performs downlink synchronization, the reference time information corresponding to the synchronization information may be applied according to the synchronization information of the target cell, for example, SFN (System Frame Number) and/or subframe (subframe) and/or slot (slot) information.
For example, after the UE receives the handover configuration (or SCG change configuration; or SCG add configuration), and the configuration information indicates the reference time information corresponding to the target PCell (or PSCell), after the UE is downlink-synchronized with the target PCell (or PSCell) (or after acquiring the SFN in the MIB of the target PCell (or PSCell)), the AS layer of the UE applies the reference time information of the target cell and sends the time information to the higher layer (e.g., application layer).
In a possible implementation manner, before S310, the UE reports an acquisition request to the network side to request to acquire the system-related information. For example, after reporting the acquisition request, the UE enters a mobility procedure due to the movement of the UE, and the source network node sends the indication information to the target network node according to the description in the method 200.
In one possible implementation manner, in order to enable the UE to acquire appropriate system-related information in time, the method may further include: and in the mobility process or after the mobility process, under the condition that a preset condition is met, reporting the acquisition request again. For example, the UE may, after a handover is successful (or SCG change is successful; or SCG addition is successful), for example, a random access with the target cell is successfully completed, and if an acquisition request previously sent in the source cell, that is, an acquisition request for the indication request or the system-related information of interest satisfies the following predetermined condition, the UE reports the acquisition request again.
Wherein the predetermined conditions include, but are not limited to:
(1) A time difference between a first time and a second time is smaller than a first predetermined value, where the first time is a time when the mobility procedure is ended, and the second time is a time when the acquisition request is reported (for example, the acquisition request reported in a source cell) before the acquisition request is reported again; that is, the time from the time of the acquisition request reported by the UE in the source cell to the time of the end of the mobility procedure is less than the first predetermined value. For example, the UE reports the request or interest information for the system information and/or the reference time information in the source cell at time t1, and completes the mobility procedure (e.g., successfully completes the random access with the target cell) at time t2, according to a first predetermined value Tmax (e.g., 500 ms) specified by a protocol or configured by the network, if (t 2-t 1) is less than or equal to Tmax, the UE needs to report the acquisition request again. Alternatively, the first and second electrodes may be,
(3) A time difference between a third time and the second time is smaller than a second predetermined value, where the third time is a time when a mobility management command is received in the mobility process, and the second time is a time when the acquisition request is reported before the acquisition request is reported again. That is, the duration from the time when the mobility procedure receives a mobility management command (e.g., a handover command, an SCG change command, or an SCG add command) at the time of the request for system information and/or reference time information or interest information sent by the source cell by the UE is less than a second predetermined value. For example, the UE reports the request or interest information for the system information and/or the reference time information in the source cell at time t1, and receives the mobility management command at time t2, according to a second predetermined value Tmax (e.g. 500 ms) specified by the protocol or configured by the network, if (t 2-t 1) is less than or equal to Tmax, the UE reports the request or interest information again.
Wherein, the second time may be one of the following:
(1) And reporting the time point of the acquisition request for the first time. That is, the second time is a time point when the UE first sends the acquisition request.
(2) And reporting the time point of the acquisition request successfully. For example, after receiving the feedback of successful reception of the acquisition request (for example, ACK feedback of the HARQ or RLC layer), the UE determines that the time point at which the acquisition request was last transmitted is the time point at which the acquisition request was successfully transmitted.
