[0004] Currently, a network-side device periodically sends a system information block (SIB) 1 to a terminal, and the sent SIB1 includes 1 bit to indicate whether the network-side device prohibits the terminal from accessing.

[0005] To achieve network energy conservation, network devices that support on-demand SIB1 transmission can send SIB1 when the terminal or network device needs it, thereby reducing network energy consumption. For example, when a terminal needs to obtain system information from a network device, it can send a request message to the network device. After receiving the request message, the network device sends SIB1 to the terminal.

[0006] However, in the scenario of sending SIB1 on demand, since the network side device will not send the SIB1 including the above-mentioned 1 bit to the terminal when the terminal does not need to obtain system information, how to determine whether the network side device prohibits terminal access becomes a technical problem that needs to be solved urgently.

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0034] The following, in conjunction with the accompanying drawings, describes in detail the system message request method, apparatus, terminal, network-side equipment, and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0035] In current network systems, all SIBs except SIB1 are collectively referred to as Open System Interconnect (OSI). A terminal can request an on-demand OSI from a base station by sending a preamble (i.e., a preamble) associated with a system message request. If the terminal receives a Random Access Response (RAR) that matches the preamble ID, it is considered to have received an acknowledgment (ACK) from the base station for the system message request and can notify upper layers.

[0036] Currently, a new bit has been introduced in SIB1 to indicate whether a cell prohibits access by NES-capable terminals that support network energy saving technology (NES-capable terminals), that is, terminals that support cell discontinuous transmission (DTX) or discontinuous reception (DRX) technology. NES-capable terminals can use this new bit in SIB1 to determine whether a cell prohibits access. Even if the cell barring indication field in the Master Information Block (MIB) indicates that a cell prohibits access, as long as the new bit in SIB1 indicates that access is not prohibited for NES-capable terminals, NES-capable terminals can still access the cell that indicates this SIB1.

[0037] To achieve network energy conservation, network devices that support on-demand SIB1 transmission can send SIB1 when the terminal or network device needs it, thereby reducing network energy consumption. For example, when a terminal needs to obtain system information from a network device, it can send a request message to the network device. After receiving the request message, the network device sends SIB1 to the terminal.

[0038] However, for on-demand SIB1 (i.e., SIB1-less) scenarios, cell barring cannot reuse the 1-bit method introduced in SIB1. This is because this 1-bit is included in SIB1, which is not sent in SIB1-less cells. Therefore, terminals supporting SIB1-less cells cannot use this method to determine whether the SIB1-less cell is barred. Therefore, determining whether the network has prohibited terminal access becomes a pressing technical issue. Furthermore, on-demand SIB1 can consider reusing the on-demand OSI mechanism, requesting the network to send SIB1 by sending a preamble related to a system message request. However, there is currently no effective solution for the conditions under which a terminal can send a preamble to request an on-demand SIB1 (i.e., how to trigger the terminal to request the network to send SIB1). As a result, the terminal sends too many invalid SIB1 request messages, resulting in ineffective on-demand SIB1 transmission.

[0039] In order to solve the above problem, in the system message request method provided in an embodiment of the present application, the terminal can receive first configuration information sent by the first network side device, and the first configuration information is: relevant configuration information for the terminal to request the second network side device to send a system message; and based on the first configuration information, perform a first operation; wherein the first operation includes at least one of the following: determining whether the second network side device prohibits terminal access; sending first information, the first information is used to request the second network side device to send a system message. Through this solution, since the terminal can perform at least one of the following based on the relevant configuration information used to request the second network side device to send a system message (for example, SIB1): determining whether the second network side device prohibits terminal access, and sending the first information to request the second network side device to send a system message, the terminal can avoid sending too much invalid system message request information based on the relevant configuration information, thereby achieving effective on-demand sending of system messages.

[0040] The embodiment of the present application provides a system message request method, and Figure 2 shows a flow chart of the system message request method provided by the embodiment of the present application. As shown in Figure 2, the system message request method provided by the embodiment of the present application may include the following steps 201 and 202.

[0041] Step 201: A terminal receives first configuration information sent by a first network-side device.

[0042] The first configuration information is configuration information related to the terminal requesting the second network-side device to send a system message.

[0043] Optionally, in an embodiment of the present application, the first network side device and the second network side device may be the same or different, that is, the first network side device and the second network side device may be the same network side device, or may be two different network side devices.

[0044] Optionally, in an embodiment of the present application, the first network-side device may be a network-side device that supports sending system messages on demand.

[0045] Optionally, in an embodiment of the present application, the second network-side device may be a network-side device that supports sending system messages on demand.

[0047] Optionally, in this embodiment of the present application, the first configuration information may include at least one of the following 1.1 to 1.7:

[0048] 1.1. Configuration information of a first signal, where the first signal is a signal for requesting system information;

[0057] In an embodiment of the present application, since the above-mentioned first configuration information can include at least one of the above-mentioned 1.1 to 1.7, the terminal can be configured to request the second network side device to send a system message through different configuration information, thereby improving the flexibility of configuring the terminal to request the system message.

[0058] Optionally, in an embodiment of the present application, the first signal may include at least one of the following: a wake-up signal (WUS), a random access preamble signal, and a channel sounding reference signal (SRS).

[0059] In an embodiment of the present application, since the above-mentioned first signal can include at least one of WUS, random access preamble signal and SRS, the above-mentioned first configuration information can include configuration information of different signals for requesting system messages, thereby enriching the composition of the first configuration information and further improving the flexibility of the related behaviors of configuring the terminal to request system messages.

[0060] Step 202: The terminal performs a first operation based on the first configuration information.

[0061] The first operation includes at least one of the following:

[0062] Determining whether the second network-side device prohibits terminal access;

[0063] Sending first information, where the first information is used to request the second network-side device to send a system message.

[0064] Optionally, in an embodiment of the present application, the first operation includes: determining whether the second network-side device prohibits the terminal from accessing. Exemplarily, the step 202 can be implemented through the following steps 202a and 202b.

[0065] Step 202a: The terminal determines whether a first condition is met according to the first configuration information.

[0066] Step 202b: When the first condition is met, the terminal determines that the second network-side device prohibits the terminal from accessing.

[0067] The first condition mentioned above includes at least one of the following:

[0068] The terminal does not support any of the above-mentioned technical features;

[0069] The terminal does not support all of the above technical features.

[0070] The value of the first counter exceeds the first value, and the first counter is used to count the number of times the terminal sends the first signal;

[0071] A first timer times out, where the first timer is a timer started after the terminal sends the first signal;

[0072] The PCI of the second network-side device obtained by the terminal is different from the PCI in the first configuration information.

[0073] Optionally, in an embodiment of the present application, the terminal may obtain the PCI of the second network-side device in any possible manner.

[0074] Exemplarily, the terminal can obtain the PCI of the second network side device through the synchronization signal or reference signal sent by the above-mentioned second network side device. The synchronization signal or reference signal may include but is not limited to at least one of the following: SSB, primary synchronization signal (Primary Synchronization Signal, PSS), secondary synchronization signal (Secondary Synchronization Signal, SSS), etc.

[0075] Optionally, in the embodiment of the present application, the timeout of the first timer can be understood as: the time after the terminal sends the first signal exceeds the first preset time.

[0076] The following is an exemplary description of a specific method in which the terminal determines whether the first condition is met according to the first configuration information.

[0077] Exemplarily, assuming that the above-mentioned first configuration information is the above-mentioned 1.1 (i.e., the configuration information of the first signal), then after receiving the first configuration information, the terminal can send the first signal according to the first configuration information, and start the above-mentioned first timer after sending the first signal; if the first timer times out, the above-mentioned first condition is met, and if the first timer does not time out, the above-mentioned first condition is not met.

[0078] As another example, assuming that the above-mentioned first configuration information is the above-mentioned 1.6 (that is, at least one technical feature supported by the above-mentioned second network side device), then after receiving the first configuration information, the terminal can determine whether it supports any or all of the at least one technical feature. If supported, the terminal can determine that the above-mentioned first condition is met; if not supported, the terminal can determine that the above-mentioned first condition is not met.

[0079] Optionally, in the embodiment of the present application, the above step 202b can be specifically implemented through the following step 202b1.

[0080] Step 202b1: When the first condition is met and the MIB of the second network side device obtained by the terminal indicates that the second network side device prohibits terminal access, the terminal determines that the second network side device prohibits terminal access.

[0081] In an embodiment of the present application, since the terminal can determine whether the above-mentioned first condition is met based on the above-mentioned first configuration information, and when the first condition is met, determine that the above-mentioned second network side device prohibits terminal access, and the first condition can include different above-mentioned contents, therefore, through different first conditions, it can be flexibly and accurately determined whether the second network side device prohibits terminal access.

[0082] Optionally, in the embodiment of the present application, the first operation includes: sending the first information. Exemplarily, the step 202 can be implemented through the following steps 202c and 202d.

[0083] Step 202c: The terminal determines whether the second condition is met based on the first configuration information.

[0084] Step 202d: When the second condition is met, the terminal sends the first information.

[0085] The second condition includes at least one of the following:

[0086] The terminal supports any one of the above-mentioned technical features;

[0087] The terminal supports all technical features of at least one of the above technical features;

[0088] The terminal does not store any valid system information of the second network side device;

[0089] A second timer times out, where the second timer is a timer started when the terminal obtains a valid system message from the second network-side device;

[0090] A third timer times out, where the third timer is: a timer started when the terminal obtains the first configuration information;

[0091] The first configuration information is valid;

[0092] The PCI of the second network-side device obtained by the terminal is the same as the PCI in the first configuration information;

[0093] The terminal obtains the SSB sent by the second network side device, but does not obtain the system message sent by the second network side device;

[0094] The terminal obtains the SSB sent by the second network side device, and the MIB carried by the SSB indicates that the second network side device allows the terminal access;

[0095] The terminal obtains the SSB sent by the above-mentioned second network side device, and the MIB carried by the SSB indicates that the second network side device prohibits the terminal from accessing.

[0096] Optionally, in an embodiment of the present application, the second timer may specifically be a timer that is started when the terminal obtains a valid system message from the second network-side device for the last time or the most recent time.

[0097] Optionally, in the embodiment of the present application, the timeout of the second timer can be understood as: the time duration after the terminal last or most recently obtained the valid system message of the second network-side device exceeds the second preset time duration.

[0098] Optionally, in an embodiment of the present application, the above-mentioned valid system message may be: a system message whose target information is the same as the target information in the above-mentioned first configuration, and the target information includes a PLMN identifier, a cell identifier and a value tag.

[0099] Optionally, in an embodiment of the present application, the first configuration information is valid, which can be understood as: the time when the terminal determines whether the second condition is met is before the validity expiration time of the first configuration information.

[0100] For example, if the validity period of the above-mentioned first configuration information is time a, then if the time when the terminal determines whether the above-mentioned second condition is met is before time a, the first configuration information is considered to be valid, and the terminal can send the above-mentioned first information at this time; if the time when the terminal determines whether the above-mentioned second condition is met is after time a, the first configuration information is considered to be invalid, and the terminal cannot send the above-mentioned first information at this time.

[0101] Optionally, in an embodiment of the present application, the terminal obtains the SSB sent by the above-mentioned second network side device, but does not obtain the system message sent by the second network side device. It can be understood that: the SSB sent by the second network side device indicates the control resource set configuration of SIB1, but the terminal does not obtain the SIB1; or, the SSB does not indicate the control resource set configuration of SIB1; or, the SSB indicates that there is no cell or cell frequency in which to reside.

[0102] For other descriptions in the above step 202c and the above step 202d, please refer to the relevant descriptions in the above step 202a and the above step 202b. In order to avoid repetition, they are not repeated here.

[0103] In an embodiment of the present application, since the terminal can determine whether the above-mentioned second condition is met based on the above-mentioned first configuration information, and send the above-mentioned first information when the second condition is met, and the second condition can include different above-mentioned contents, the terminal can be flexibly triggered to send the first information through different second conditions.

[0104] Optionally, in the embodiment of the present application, the first network side device is the same as the second network side device, and the first operation includes: sending the first information. Exemplarily, the step 202 can be implemented by the following step 202e.

[0105] Step 202e: The terminal sends first information to the first network-side device based on the first configuration information.

[0106] It can be understood that when the above-mentioned first network side device is the same as the above-mentioned second network side device, the terminal receives the above-mentioned first configuration information from one network side device, and sends the above-mentioned first information to the network side device based on the first configuration information to request the network side device to send a system message; after receiving the first information, the network side device can send a system message.

[0107] In the embodiment of the present application, since when the first network side device is the same as the second network side device, the terminal can send the first information to the device sending the first configuration information, thereby simplifying the process of requesting system messages.

[0108] Optionally, in the embodiment of the present application, the first network side device is different from the second network side device, and the first operation includes: sending the first information. Exemplarily, the step 202 can be implemented by the following step 202f.

[0109] Step 202f: The terminal sends the first information to the first network side device or the second network side device based on the first configuration information.

[0110] Optionally, in an embodiment of the present application, when the above-mentioned first network side device is different from the above-mentioned second network side device, if the terminal sends the above-mentioned first information to the above-mentioned first network side device, then after receiving the first information, the first network side device can send a request message to the second network side device to request the second network side device to send a system message.

[0111] Optionally, in an embodiment of the present application, when the above-mentioned first network side device is different from the above-mentioned second network side device, if the terminal sends the above-mentioned first information to the above-mentioned second network side device, the second network side device can directly send a system message after receiving the first information.

[0112] In an embodiment of the present application, since when the above-mentioned first network side device is different from the above-mentioned second network side device, the terminal can send the above-mentioned first information to the first network side device or the second network side device, the flexibility of sending the first information can be improved, and the second network side device can be flexibly requested to send a system message.

[0113] In the system message request method provided in an embodiment of the present application, since the terminal can perform at least one of the following based on the relevant configuration information used to request the second network side device to send a system message (for example, SIB1): determine whether the second network side device prohibits terminal access, and send first information to request the second network side device to send a system message, based on the relevant configuration information, the terminal can be prevented from sending too much invalid system message request information, thereby achieving effective on-demand sending of system messages.

[0114] The following is an illustrative description of the system message request method provided in an embodiment of the present application.

[0115] Exemplarily, assuming that the terminal supports at least one of the above technical features (for example, RedCap), and the terminal hopes to reside in a cell supporting RedCap, and the terminal resides in the coverage of cell one and cell two; then if cell one is the cell where the terminal resides, cell two is a cell that supports SIB1-less energy-saving features, and the terminal receives energy-saving configuration information of energy-saving cell two in cell one (that is, the above-mentioned first configuration information), the energy-saving configuration information indicates that energy-saving cell two only supports RedCap technical features, then:

[0116] For a terminal supporting RedCap, if the terminal detects the SSB of energy-saving cell 2 but cannot detect SIB1, and the PCI of the SSB is included in the energy-saving configuration information, then the terminal considers that energy-saving cell 2 is in the not barred state and can send WUS / preamble to cell 2 to request cell 2 to send on-demand SIB1;

[0117] For a terminal that does not support RedCap, if the terminal detects the SSB of energy-saving cell 2 but cannot detect SIB1, considering that energy-saving cell 2 only supports RedCap terminal residency, the terminal that does not support RedCap considers that energy-saving cell 2 is in a barred state and cannot send WUS / preamble to cell 2 to request cell 2 to send on-demand SIB1;

[0118] Assume that there is energy-saving cell three, and the terminal receives the energy-saving configuration information of energy-saving cell three in cell one; then if the energy-saving configuration information does not indicate that energy-saving cell two supports any specific technical features (for example, RedCap, NTN or MBS, etc.), then for any terminal (including terminals that support specific technical features and normal terminals that do not support specific technical features), if the SSB of energy-saving cell three is detected but SIB1 is not detected, then the terminal can send WUS / preamble to cell three to request cell three to send on-demand SIB1.

[0119] As another example, a method for determining whether a SIB1-less cell prohibits terminal access is: reusing the cellBarred field in the MIB, if the cellBarred field in the cell MIB message is barred, it indicates that the cell prohibits terminal access; if the cellBarred field is barred, it indicates that the cell allows terminal access, that is, terminals supporting the SIB1-less cell feature are allowed to send WUS / preamble to request the cell to send on-demand SIB1. A method for determining whether a SIB1-less cell allows terminal access that supports the SIB1-less cell feature is: if the cellBarred field in the cell MIB message is barred, but the PCI decoded from the SSB of the cell is in the SIB1-less cell energy-saving cell configuration, it can be considered that the cell prohibits terminal access that does not support the SIB1-less cell feature, but allows terminal access that supports the SIB1-less cell feature, that is, terminals supporting the SIB1-less cell feature are allowed to send WUS / preamble to request the cell to send on-demand SIB1. A method for determining whether a SIB1-less cell allows access by terminals that support the SIB1-less cell feature is: if the cellBarred field in the cell MIB message is barred, but the energy-saving cell configuration indicates that the cell supports certain technical features (for example, RedCap), the RedCap terminal may consider that the cell prohibits access by terminals that do not support RedCap, but allows access by terminals that do support RedCap, that is, allows terminals that do support RedCap to send WUS / preamble to request the cell to send on-demand SIB1.

[0120] As another example, a terminal supporting the SIB1-less cell feature is allowed to request the network-side device to send SIB1 from the SIB1-less cell only if at least one of the following conditions is met; one of the conditions is that the terminal detects the SSB sent by the SIB1-less cell, and the PCI decoded from the SSB is included in the SIB1-less cell energy-saving cell configuration. At this time, the terminal believes that it can request an on-demand SIB1 from the cell. Another condition is that after the terminal obtains a valid SIB1 message from the cell, it believes that the SIB1 is still valid within 3 hours. After 3 hours (that is, the above-mentioned second timer times out), the terminal discards the stored valid SIB1 message. At this time, if the cell enters the energy-saving state and does not send SIB1, the terminal cannot obtain SIB1, and then the terminal can request an on-demand SIB1 from the cell. One condition is that a terminal supporting certain technical features (eg, RedCap) can request on-demand SIB1 from a SIB1-less cell supporting the technical feature. Conversely, a terminal not supporting the technical feature is not allowed to request on-demand SIB1 from a SIB1-less cell supporting the first technical feature.
