Fig. 2 is a block diagram of a network system under a DC architecture according to an embodiment of the present invention, as shown in fig. 2, a terminal 11 is in a dual connection state, where the terminal 11 is connected to an MCG (Master Cell Group, primary cell group) and an SCG (Secondary Cell Group ) simultaneously, where the MCG corresponds to an MN (Master Node) 121 of a network side device 12, and the SCG corresponds to an SN (Secondary Node) 122 of the network side device 12.

Fig. 3 is a flowchart of a system information transmission method applied to the network system shown in fig. 1 to 2 according to an embodiment of the present invention. As shown in fig. 3, the method comprises the steps of:

step 201: and under the condition that the first cell is determined to have specific system information, the terminal reports a system information request message to the network side equipment.

Step 202: and the network side equipment receives the system information request message reported by the terminal.

The system information request message is used for requesting specific system information of the first cell; the first cell may include at least one of a cell of the SCG and a secondary cell of the MCG. The first cell is a non-PCell, i.e., the first cell does not include a PCell. For example, the first Cell may be a primary Cell of the SCG, i.e. PSCell (Primary Secondary Cell, primary serving Cell of the Secondary Cell group), a Secondary Cell of the SCG, i.e. SCG SCell (Secondary Cell), or a Secondary Cell of the MCG, i.e. MCG SCell.

Specific system information may be understood as system information of interest to the terminal, or system information required by the terminal. For example, the specific system information of the first cell may be SIB9 of PSCell or SCG SCell (System Information Block, system information block 9)

In the embodiment of the present invention, the terminal may determine that the first cell has specific system information, so step 201 may be: and the terminal reports the system information request message to the network side equipment under the condition that the first cell is determined to have the specific system information. Of course, the embodiment of the present invention does not exclude an embodiment in which the other communication device determines that the first cell has the specific system information, and in a case in which the other communication device determines that the first cell has the specific system information, the other communication device may inform the terminal of the determination result through an appropriate path.

In the embodiment of the present invention, the network side device may be the network side device 11 in fig. 1, or may be the MN121 or the SN122 in fig. 2.

Fig. 4 is a flowchart of a system information transmission method applied to a terminal according to an embodiment of the present invention. As shown in fig. 4, the system information transmission method is applied to a terminal, and the method comprises the following steps:

Step 301: reporting a system information request message to network side equipment under the condition that a first cell is determined to have specific system information, wherein the system information request message is used for requesting the specific system information of the first cell; the first cell includes at least one of a cell of an SCG and a secondary cell of an MCG.

The network side device may be the network side device 11 in fig. 1, or the MN121 or SN122 in fig. 2. That is, in the case where the terminal is in the dual connection state, the network side device may be MN or SN.

In the embodiment of the invention, the terminal can report the system information request message to the network side equipment in different states, such as IDLE, INACTIVE or CONNECTED states.

In the embodiment of the present invention, the first cell is a non-PCell, i.e., the first cell does not include a PCell.

In the embodiment of the invention, the terminal can request to acquire the system information of various different types of cells based on the communication requirement, so that for a specific deployment scenario, for example, EN-DC (E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR, E-UTRA is MCG, NR is double connection of SCG), the terminal can acquire the system information of a specific NR (New RAT, new air interface) cell, thereby being capable of acquiring the system information service of NR.

In the embodiment of the present invention, the terminal may determine that the first cell has specific system information, so step 301 may be: and the terminal reports the system information request message to the network side equipment under the condition that the first cell is determined to have the specific system information.

In the embodiment of the present invention, there are various embodiments in which the terminal determines that the first cell has specific system information, and each embodiment is described below.

Optionally, before the system information request message is reported to the network side device, the method further includes:

determining that the first cell has the specific system information according to a target system information block, wherein the target system information block comprises at least one of a system information block of a cell of the SCG and a system information block of a cell of the MCG; or alternatively, the process may be performed,

And determining that the first cell has the specific system information according to a message of a higher layer configuration.

In this embodiment, the terminal may determine whether the first cell has specific system information by reading a system information block of the first cell, for example, the terminal may determine whether the SCG PSCell or SCG Scell has specific system information by reading a system information block of the SCG PSCell or SCG Scell. For another example, the terminal may determine whether the MCG SCell has specific system information by reading a system information block of the MCG SCell.

As an example, the terminal may determine whether the first cell has SIB9 of interest to the terminal by reading scheduling information in SIB1 (System Information Block, system information block 1) of the first cell.

The terminal may also determine whether the first cell has specific system information by reading a system information block of a non-first cell. For example, the terminal may determine whether the SCG PSCell or SCG SCell has specific system information by reading a system information block of the MCG PCell or the MCG SCell. For another example, the terminal may determine whether the MCG SCell has specific system information by reading a system information block of the MCG PCell.

As an example, the terminal may read the indication information through SIBx of the MCG PCell, the indication information indicating that the SCG SCell has SIB9 of interest to the terminal.

The terminal may also determine, through a message configured by a higher layer, whether the first cell has specific system information, for example, the network side device indicates, through a terminal-specific RRC (Radio Resource Control ) message (e.g., an rrcrecon configuration message), that the first cell has SIB9 of interest to the terminal.

The above various alternative embodiments for determining that the first cell has specific system information for the terminal, any of which may be selected by the terminal to determine that the first cell has specific system information.

Optionally, the system information request message includes an identification of the specific system information and an identification of the first cell.

The identification of the specific system information may include at least one of a system information identification and a system information block identification. For example, the scheduling information that may be in SIB1 described above indicates a system information identity-1 (SI index-1), which may include 1 or more system information blocks. For example, the system information block identification may be SIB9 as described above.

The identification of the first cell may include at least one of:

cell group identification (e.g., MCG or SCG) of the first cell;

cell type identification of the first cell (e.g., PCell, SCell, PSCell or SpCell);

A serving cell identity (e.g., serving cell-1) of the first cell;

a secondary cell identity (e.g., SCell-1) of the first cell;

a physical cell identity (Physical Cell Identity, PCI for short) (e.g., PCI-1) of the first cell;

a frequency point corresponding to the first cell (e.g., ARFCN-1 (Absolute Radio Frequency Channel Number, absolute radio frequency channel number));

a cell global identity (Cell Global Identifier, CGI) of the first cell (e.g., CGI-1);

the radio technology type identity of the first cell (e.g. NR, LTE or UMTS (Universal Mobile Telecommunication System, universal mobile telecommunications system), etc.).

It should be noted that, the cell group identifier or the cell identifier may be implicitly indicated by SIB reported by the terminal. For example, assuming that the terminal reports a system information request message through SRB3, the terminal requests specific system information that is SCG; assuming that the terminal reports the system information request message through the SRB1, the terminal requests specific system information of the MCG. For another example, assuming that the terminal reports the system information request message through SRB3, the terminal requests specific system information of SCG PSCell; assuming that the terminal reports the system information request message through the SRB1, the terminal requests specific system information for the MCG SCell.

In the embodiment of the present invention, after the terminal reports the system information request message to the network side device, the method may further include:

and receiving a response message sent by the network side equipment, wherein the response message comprises the specific system information of the first cell.

The network side device may send the response message to the terminal through dedicated signaling, and specifically, the network side device may send specific system information of the first cell to the terminal through dedicated signaling according to the system information request message. For example, the network side device may transmit specific system information of the first cell requested by the terminal to the terminal through the rrcrecon configuration message.

In addition, the network side device may send the response message to the terminal in a broadcast manner, or may send the response message to the terminal in a unicast manner (for example, through dedicated RRC signaling of the connected terminal).

Optionally, the response message includes an identification of the specific system information and an identification of the first cell.

For example, when the identifier of the specific system information included in the response message indicates that the specific system information is the system information 9 and the identifier of the first cell included in the response message indicates that the cell group corresponding to the first cell is the SCG, the PSCell of the first cell is the SCG may be agreed by the protocol, and the specific system information is the system information 9 of the PSCell of the SCG.

The identification of the specific system information and the identification of the first cell can be referred to the description of the identification of the specific system information and the identification of the first cell, and the description is omitted for avoiding repetition.

Optionally, the response message further includes identification information of the terminal.

Further, the identification information of the terminal includes an identification of the terminal or an identification of a transmission channel corresponding to the terminal. The identifier of the transmission channel corresponding to the terminal may be an Xn interface identifier.

In this embodiment, since the response message includes the identification information of the terminal, the terminal can identify the sending target of the response message according to the identification information of the terminal carried in the response message.

In the embodiment of the present invention, when it is determined that the first cell has specific system information, various embodiments of reporting the system information request message to the network side device by the terminal are described below.

Optionally, if the first cell is a cell of the SCG and the SCG is configured with SRB3 (Signaling Radio Bearer, signaling bearer 3), the terminal reports the system information request message to the network side device through SRB1 (Signaling Radio Bearer, signaling bearer 1) or SRB 3; or alternatively, the process may be performed,

If the first cell is the cell of the SCG and the SCG is not configured with SRB3, the terminal reports the system information request message to the network side equipment through SRB 1; or alternatively, the process may be performed,

and if the first cell is the auxiliary cell of the MCG, the terminal reports the system information request message to the network side equipment through SRB 1.

Wherein SRB1 is a signaling bearer between the terminal and the MCG, and SRB3 is a signaling bearer between the terminal and the SCG.

Further, when the terminal is in the dual-connection state, the terminal reports the system information request message to the network side device through the SRB1, which can be understood that the terminal reports the system information request message to the MN through the SRB 1. And the terminal reports the system information request message to the network side device through the SRB3, it can be understood that the terminal reports the system information request message to the SN through the SRB 3.

The above are various optional embodiments of reporting the system information request message to the network side device by the terminal, and the terminal may select any one of the embodiments to report the system information request message to the network side device.

As described above, when the terminal is in the dual-connection state, the network side device in the embodiment of the present invention may be either the MN or the SN, that is, the terminal may report the system information request message to the MN or the SN.

If the specific system information requested by the terminal is the system information of the SCG cell, the terminal can report the system information request message to the MN, specifically, the terminal can report the system information request message to the MN through SRB 1; the terminal may also report the system information request message to the SN, and specifically, the terminal may report the system information request message to the SN through SRB 3.

If the specific system information requested by the terminal is the system information of the MCG SCell, the terminal may report the system information request message to the MN, specifically, the terminal may report the system information request message to the MN through the SRB 1.

Correspondingly, in the case that the network side equipment is the MN, the response message can be sent to the terminal through the SRB 1; in the case that the network side device is SN, the response message may be sent to the terminal through SRB 3. For example, assuming that the specific system information requested by the terminal is system information (e.g., system information-9) on the SCG PSCell and the terminal is configured with SRB3, the network side device SN may transmit the specific system information requested by the terminal to the terminal through SRB 3.

Optionally, if the network side device is an MN and the first cell is a cell of the SCG, the specific system information is acquired from the SN by the MN and is sent to the terminal through the MN when the terminal is in the dual-connection state.

In this embodiment, when the terminal is in the dual connection state, if the node that receives the system information request message is MN and the specific system information requested by the terminal is the system information of the cell of the SCG, the MN may send the system information request message to the SN. The SN may transmit the content of the specific system information requested by the terminal to the MN according to the system information request message when receiving the system information request message transmitted by the MN, and the MN may transmit the content of the specific system information to the terminal after receiving the content of the specific system information transmitted by the SN.

This embodiment may be applied to the network system shown in fig. 2, and fig. 5 is a system information transmission method applied to the network system shown in fig. 2 provided by the embodiment of the present invention. As shown in fig. 5, the method comprises the steps of:

Further, the system information request message, the first message sent by the MN to the SN, the first response message sent by the SN to the MN, and the second response message sent by the MN to the terminal may all include an identifier of specific system information and an identifier of the first cell of the SCG.

Further, the system information request message, the first message sent by the MN to the SN, the first response message sent by the SN to the MN, and the second response message sent by the MN to the terminal may further include identification information of the terminal. Therefore, the MN and the SN can identify the relevant information of the request terminal of the system information request message according to the identification information of the terminal carried in the message, thereby being beneficial to improving the communication performance.
