技术领域Technical field
本公开涉及通信技术领域，特别涉及一种***信息传输方法、装置、网络设备及终端。The present disclosure relates to the field of communications technologies, and in particular, to a system information transmission method, apparatus, network device, and terminal.
背景技术Background technique
在新一代无线通信***(5G或空口NR***)中，网络带宽可以远大于终端传输带宽，因此引入部分带宽(BWP，Band Width Part)的概念，一个小区载波带宽可以划分为多个BWP。基站可以通过专用信令为终端UE配置多个BWP，并且Rel-15版本UE只能有一个激活的上行BWP和一个激活的下行BWP。该激活BWP可能不同于可以周期性广播***信息的initial(初始)BWP。In a new generation wireless communication system (5G or air interface NR system), the network bandwidth can be much larger than the terminal transmission bandwidth. Therefore, the concept of a partial bandwidth (BWP, Band Width Part) is introduced, and one cell carrier bandwidth can be divided into multiple BWPs. The base station can configure multiple BWPs for the terminal UE through dedicated signaling, and the Rel-15 version UE can only have one active uplink BWP and one active downlink BWP. The active BWP may be different from the initial BWP that can periodically broadcast system information.
关于BWP：About BWP:
在传统LTE***中，网络侧角度的小区载波带宽小于或等于终端接收带宽20MHz，因此网络侧总是将小区的上下行总带宽配置给终端，终端可以在整个小区载波带宽上工作。在NR***中，网络侧载波带宽可以高达400MHz，远远大于终端的接收能力。因此，引入BWP的概念，即将网络侧的大带宽划分为多个部分带宽BWP，将一个或多个BWP配置给终端，并激活部分配置的BWP为终端进行上下行传输，激活的下行BWP称为active DL BWP，激活的上行BWP称为active UL BWP。在R15版本中，对终端来说，一个时刻只允许激活一个DL BWP和一个UL BWP，非激活的BWP不能进行上下行信令和数据传输。In the traditional LTE system, the cell carrier bandwidth of the network side is less than or equal to the terminal receiving bandwidth of 20 MHz. Therefore, the network side always allocates the total uplink and downlink bandwidth of the cell to the terminal, and the terminal can work on the entire cell carrier bandwidth. In the NR system, the network side carrier bandwidth can be as high as 400 MHz, which is much larger than the terminal's receiving capability. Therefore, the concept of the BWP is introduced, that is, the large bandwidth of the network side is divided into multiple partial bandwidth BWPs, one or more BWPs are configured to the terminal, and the partially configured BWP is activated for the terminal to perform uplink and downlink transmission, and the activated downlink BWP is called Active DL BWP, the active upstream BWP is called active UL BWP. In the R15 version, for a terminal, only one DL BWP and one UL BWP are allowed to be activated at a time, and the inactive BWP cannot perform uplink and downlink signaling and data transmission.
其中，激活BWP可以通过基站使用物理层信令DCI(Downlink Control Information，下行控制信息)显式变更，也可以通过网络侧配置的 BWP-Inactivity Timer定时器自动变更到default(默认)BWP。The active BWP can be changed explicitly by the base station using the Downlink Control Information (DCI), or can be automatically changed to the default (default) BWP by the BWP-Inactivity Timer configured on the network side.
IDLE和inactive态UE通过监听initial BWP获取***信息以及paging(寻呼)消息，网络侧在initial BWP上广播***信息。The IDLE and inactive UEs obtain system information and paging messages by listening to the initial BWP, and the network side broadcasts system information on the initial BWP.
NR***中，***信息分为小区级***信息以及区域级***信息，对于区域级***信息，对于多个基站gNB可以共享相同的***信息配置，SIB1中可以广播***信息的area ID(区域标志)以及每个SIB的版本即value tag(版本标志)，UE可以按照area ID以及value tag存储和管理***信息。对于更新的***信息，UE可以检查对应的area ID以及value tag，如果UE已经存储该版本的SIB，则可以避免重新获取该***信息。In the NR system, system information is divided into cell-level system information and regional-level system information. For regional-level system information, the same system information configuration can be shared for multiple base stations gNB, and the area ID (area flag) of the system information can be broadcast in SIB1. And the version of each SIB, that is, the value tag, the UE can store and manage system information according to the area ID and the value tag. For the updated system information, the UE may check the corresponding area ID and the value tag. If the UE has already stored the version of the SIB, the system information may be re-acquired.
由上可知，相关技术对于通过专用信令传输***信息并没有提供明确的方案，也就是说相关技术中无法准确地通过专用信令传输***信息。As can be seen from the above, the related art does not provide an explicit solution for transmitting system information through dedicated signaling, that is, the related art cannot accurately transmit system information through dedicated signaling.

针对网络设备主动通过专用信令向终端发送***信息的情况，所述接收网络设备通过专用信息发送的***信息的步骤包括：接收网络设备在终端为具有预设业务的连接态终端时发送的***信息，其中预设业务可以是高可靠低时延通信业务，但不限制为该业务；或接收网络设备发送的预设的***信息，其中预设的***信息可以是PWS通知，主信息块MIB，或者基于需求的***信息on-demand SI，但不限制为以上***信息；或接收网络设备在终端为在当前工作带宽或当前工作激活部分带宽内不能接收广播***信息的连接态终端时发送的***信息，其中，不能接收广播***信息的连接态终端为在当前工作带宽或当前激活部分带宽内没有配置以下至少一项的终端：获取***信息的控制资源集合，获取***信息的搜索空间，获取***信息更新通知的寻呼的控制资源集合，以及获取***信息更新通知的寻呼的搜索空间(其 中以上所述配置可以是通过专用信令配置，或通过***信息配置给UE)。For the case that the network device actively sends the system information to the terminal through dedicated signaling, the step of receiving the system information sent by the network device by using the dedicated information includes: receiving the system that the network device sends when the terminal is the connected state terminal with the preset service Information, wherein the preset service may be a high-reliability low-latency communication service, but is not limited to the service; or receiving preset system information sent by the network device, where the preset system information may be a PWS notification, the main information block MIB Or demand-based system information on-demand SI, but not limited to the above system information; or the receiving network device is sent when the terminal is a connected-mode terminal that cannot receive broadcast system information within the current working bandwidth or the current working active part of the bandwidth System information, wherein the connected state terminal that cannot receive the broadcast system information is a terminal that does not configure at least one of the following in the current working bandwidth or the currently activated part of the bandwidth: acquiring a control resource set of the system information, acquiring a search space of the system information, and acquiring Control resource set for paging of system information update notification And a search space for obtaining a page of the system information update notification (wherein the above configuration may be configured by dedicated signaling or configured by the system information to the UE).
下面结合网络设备和终端两侧，对本公开实施例提供的***信息传输方法进行进一步说明。The system information transmission method provided by the embodiment of the present disclosure is further described below in conjunction with the network device and the terminal.
针对上述技术问题，本公开实施例提供一种***信息传输方法，包括：For the above technical problem, an embodiment of the present disclosure provides a system information transmission method, including:
网络侧通过专用信令发送***信息给UE，可以是基于UE请求时，网络侧根据UE的请求信息发送相应的***信息给UE，也可以是网络侧在特殊时刻或针对特殊UE，主动通过专用信令发送***信息给UE，例如，网络侧决定在下一个***信息修改周期更新***信息，则在本***信息修改周期内通过专用信令将更新的***信息发送给UE，UE存储对应的***信息并在下一个修改周期将更新的***信息生效，或在下一个***信息修改周期边界发送更新的***信息给UE，UE接收到对应的***信息则存储该信息，并立即生效对应的***信息或成功发送网络侧响应消息后即生效；或者网络可以在任意时刻发送更新的***信息给UE，UE接收后即生效，或成功发送网络侧响应消息后即生效。对于网络侧发送的PWS相关通知信息，UE接收到含有PWS的***信息，则立即生效。The network side sends the system information to the UE through dedicated signaling. The network side may send the corresponding system information to the UE according to the request information of the UE, or may be actively used by the network side at a special time or for a special UE. The signaling system information is sent to the UE. For example, the network side decides to update the system information in the next system information modification period, and then sends the updated system information to the UE through dedicated signaling in the system information modification period, and the UE stores the corresponding system information. And the updated system information is valid in the next modification period, or the updated system information is sent to the UE at the next system information modification period boundary, and the UE stores the information when the corresponding system information is received, and immediately responds to the corresponding system information or successfully sends the information. After the network side responds to the message, it can take effect; or the network can send the updated system information to the UE at any time. The UE takes effect after receiving it, or takes effect after successfully sending the network side response message. For the PWS related notification information sent by the network side, if the UE receives the system information containing the PWS, it will take effect immediately.
下面针对网络侧主动通过专用信令向终端发送***信息和网络侧接收到终端请求再通过专用信令向终端发送***信息两种情况进行分别说明。The following describes the case where the network side actively sends system information to the terminal through dedicated signaling, and the network side receives the terminal request and then sends the system information to the terminal through dedicated signaling.
情况一：不基于UE请求，网络侧决定发送***信息专用信令消息给UE。如图3所示。Case 1: The network side decides not to send a system information specific signaling message to the UE based on the UE request. As shown in Figure 3.
网络侧通过发送paging DCI通知连接态UE***信息更新、ETWS(Earthquake and Tsunami Warning System，地震海啸预警***)或CMAS(Commercial Mobile Alert Service，商业移动报警***)通知，继而通过专用信令发送更新的***信息、ETWS或CMAS消息，或直接通过***信息专用信令通知UE进行***信息更新或PWS通知。The network side notifies the connected state UE system information update, the ETWS (Earthquake and Tsunami Warning System) or the CMAS (Commercial Mobile Alert Service) notification by sending a paging DCI, and then sends the updated by dedicated signaling. System information, ETWS or CMAS messages, or directly notify the UE via system information-specific signaling for system information update or PWS notification.
对于***信息更新情况，UE存储当前使用的***信息，UE只需要获取更新后的具体的***信息即可，例如MIB(Master Information Block，主信息块)，SIB1(System Information Block 1，***消息块1)，SIB2(System Information Block 2，***消息块2)或包含更改SIB的SI，无需获取全部的***信息，而网络侧可以确定自身更新的具体的***消息SI或***消息块 SIB(SI、SIB可以认为是网络调度***信息的粒度，SI可以是多个SIB)，例如主信息块MIB，SIB1，SIB2，或包含更改的SIB的SI，甚至更新的具体IE(Information element，消息元素)，所以UE可以通过如下方式通过专用信令获取更新的***信息：For the system information update, the UE stores the currently used system information, and the UE only needs to obtain the updated specific system information, such as MIB (Master Information Block), SIB1 (System Information Block 1, system message block). 1), SIB2 (System Information Block 2) or the SI including the change SIB, without acquiring all system information, and the network side can determine the specific system message SI or system message block SIB (SI, which is updated by itself). The SIB can be considered as the granularity of the network scheduling system information, and the SI can be multiple SIBs, for example, the primary information block MIB, SIB1, SIB2, or the SI including the changed SIB, or even the updated specific IE (Information Element). Therefore, the UE can obtain updated system information through dedicated signaling as follows:
(1)网络通过***信息专用信令发送更新的***信息给UE，该专用信令中包含其中一项或多项：(1) The network sends the updated system information to the UE through the system information dedicated signaling, where the dedicated signaling includes one or more of the following:
-***信息配置；- system information configuration;
-***信息版本信息，例如area ID和/或value tag；- system information version information, such as area ID and / or value tag;
-显式或隐式的***信息更新指示；- explicit or implicit system information update instructions;
其中***信息配置可以为基于当前应用的***信息的delta configuration(变量配置)方式进行配置，即只包含更新的MIB(Master Information Block，主信息块)或SIB或SI中更新的IE，对于没有更新的IE，专用信令消息中可以不携带，网络侧和UE默认缺省的IE使用以前的配置。The configuration of the system information may be configured in a delta configuration manner based on the system information of the current application, that is, only the updated MIB (Master Information Block) or the updated IE in the SIB or SI, for no update. The IE may not be carried in the dedicated signaling message, and the default configuration of the IE on the network side and the UE uses the previous configuration.
也可以是full configuration(全配置)方式，即包含完整的***信息单元所有的配置的信息元素，该***信息单元可以是SIB，MIB或SI。对于缺省的IE，网络侧和UE认为该IE没有配置。则按照该IE缺省的处理方法处理该IE，例如删除该配置或使用默认配置等。It may also be a full configuration mode, that is, an information element containing all the configurations of the complete system information unit, which may be SIB, MIB or SI. For the default IE, the network side and the UE consider that the IE is not configured. The IE is processed according to the default processing method of the IE, for example, deleting the configuration or using a default configuration.
其中包含的SIB或SI可以是部分SIB或SI，例如更新的SIB或SI；或必须的SIB(接入网络必须使用的一些SIB，例如LTE中UE接入网络必须获得MIB、SIB1和SIB2)或SI，例如SIB1；或所有SIB或SI。The SIB or SI included therein may be a partial SIB or SI, such as an updated SIB or SI; or a mandatory SIB (some SIBs that the access network must use, such as a UE access network in LTE must obtain MIB, SIB1, and SIB2) or SI, such as SIB1; or all SIB or SI.
其中***信息版本信息可以是所有SIB对应的版本信息，或者部分SIB对应的版本信息。该版本信息可以只包含value tag，或包含value tag以及area ID。The system information version information may be version information corresponding to all SIBs or version information corresponding to some SIBs. The version information can contain only the value tag, or the value tag and the area ID.
(2)UE接收到网络侧通过专用信令发送的***信息后该***信息立即生效或在下一个修改周期生效。(2) After the UE receives the system information sent by the network side through dedicated signaling, the system information takes effect immediately or takes effect in the next modification period.
该专用信令可以为新定义的专用消息，或已经定义的消息，例如RRC连接重配消息。The dedicated signaling may be a newly defined dedicated message, or an already defined message, such as an RRC Connection Reconfiguration message.
例如：E.g:
网络侧在发送通知***信息更新通知和ETWS和/或CMAS通知的paging  DCI的***信息修改周期内，通过专用信令将更新的***信息、ETWS或CMAS通知消息发送给UE。The network side transmits the updated system information, ETWS or CMAS notification message to the UE by dedicated signaling within a system information modification period in which the notification system information update notification and the paging DCI of the ETWS and/or CMAS notification are sent.
-如果该专用信令携带PWS消息，则该PWS消息立即生效；- if the dedicated signaling carries a PWS message, the PWS message takes effect immediately;
-如果该专用信令是在通知***信息更新paging DCI之后同一个***信息修改周期发送，并且携带更新的***信息，该***信息将在下个修改周期内生效。- If the dedicated signaling is sent in the same system information modification period after notifying the system information update paging DCI, and carrying the updated system information, the system information will take effect in the next modification period.
或，or,
网络侧在发送通知***信息更新通知paging DCI之后，下一个***信息修改周期通过专用信令发送更新的***信息给UE。则UE接收到该消息后立即生效。After the network side sends the notification system information update notification paging DCI, the next system information modification period sends the updated system information to the UE through dedicated signaling. Then the UE takes effect immediately after receiving the message.
或，or,
基于网络需求发送***信息给UE，UE接收到该***信息后立即生效。例如网络侧不发送通知***信息更新的paging DCI给UE，网络侧决定进行***信息更新后则发送专用信令携带更新后的***信息给UE，或网络发送paging DCI通知后，在下一个***信息修改周期内，由于调度等原因，在任意时刻网络发送携带更新后的***信息的专用信令给UE，或对于具有特殊业务的UE，例如URLLC(Ultra-Reliable and Low Latency Communications，高可靠低时延通信)，网络决定通过专用信令发送更新的***信息给UE，UE接收到该***信息后立即生效或在成功发送网络侧响应消息后即生效。The system information is sent to the UE based on the network requirement, and the UE takes effect immediately after receiving the system information. For example, the network side does not send the paging DCI that notifies the system information update to the UE, and the network side decides to send the dedicated signaling to carry the updated system information to the UE after the system information is updated, or after the network sends the paging DCI notification, the next system information is modified. During the period, the network sends dedicated signaling carrying the updated system information to the UE at any time due to scheduling, etc., or for UEs with special services, such as URLLC (Ultra-Reliable and Low Latency Communications), high reliability and low latency. The network determines that the updated system information is sent to the UE through dedicated signaling. The UE takes effect immediately after receiving the system information or takes effect after successfully transmitting the network side response message.
或，or,
网络发送***信息专用信令消息，该消息隐式或显式携带***更新指示，则该消息中如果包含PWS消息，则立即生效，否则，则UE存储该消息在下一个***信息修改周期使其生效。例如网络侧不发送通知***信息更新的paging DCI给UE，网络侧决定进行***信息更新后则发送专用信令携带更新后的***信息给UE，或对于具有特殊业务的UE，例如URLLC(Ultra-Reliable and Low Latency Communications，高可靠低时延通信)，网络决定通过专用信令发送更新的***信息给UE，UE接收到该***信息后存储更新后的***信息，在下一个***信息修改周期内生效。The network sends a system information-specific signaling message, and the message implicitly or explicitly carries the system update indication, if the message includes the PWS message, the message takes effect immediately; otherwise, the UE stores the message in the next system information modification period to take effect. . For example, the network side does not send the paging DCI that notifies the system information update to the UE. After the network side decides to update the system information, the network side sends the dedicated signaling to carry the updated system information to the UE, or for the UE with special service, such as URLLC (Ultra- Reliable and Low Latency Communications, the network decides to send updated system information to the UE through dedicated signaling, and the UE stores the updated system information after receiving the system information, and takes effect in the next system information modification period. .
该方法可以应用于不能接收广播***信息的UE，例如不能广播***信息 的BWP内的连接态UE，或者可以广播***信息的BWP内没有配置对应获得***信息或***信息通知的paging的控制资源或搜索空间的连接态UE，或者可以广播***信息的BWP内没有发送通知***信息修改通知的paging DCI的连接态UE，或者具有特殊业务的UE，例如URLLC业务，或者特殊***信息消息，例如PWS通知或MIB消息，网络通过专用信令为该BWP上的连接态UE发送该消息。但不限于以上场景。The method may be applied to a UE that cannot receive broadcast system information, for example, a connected UE in a BWP that cannot broadcast system information, or a control resource that does not have a paging associated with obtaining system information or system information notification in a BWP that can broadcast system information or a connected state UE of a search space, or a connected state UE of a paging DCI that does not transmit a notification system information modification notification in a BWP that can broadcast system information, or a UE having a special service, such as a URLLC service, or a special system information message, such as a PWS notification Or MIB message, the network sends the message to the connected UE on the BWP through dedicated signaling. But not limited to the above scenes.
情况二，基于UE请求的方法，网络侧发送***信息专用信令消息，如图4所示。Case 2: Based on the method requested by the UE, the network side sends a system information specific signaling message, as shown in FIG. 4 .
由于UE可以存储不同版本的***信息，当UE存储的***信息版本中包含即将更新的***信息版本，则UE可以不用重新读取更新后的SI或SIB(更新后的SIB)，而可以在对应的时刻使用已存储的该版本的***信息。基于UE请求可以节省空口开销。UE发送给网络侧的***信息请求消息中可以携带已存储的SI或SIB的版本号，网络侧接收到请求消息后可以根据UE存储的***信息版本选择性的发送***信息给UE，对于UE没有存储的即将更新使用的版本的***信息将该***信息发送给UE，对于已经存储的即将更新使用的版本的***信息，网络侧通知UE即将更新使用的版本。Since the UE can store different versions of system information, when the system information version stored by the UE includes the system information version to be updated, the UE may not need to re-read the updated SI or SIB (updated SIB), but may correspond to The moment to use the stored system information for that version. Air interface overhead can be saved based on UE requests. The system information request message sent by the UE to the network side may carry the stored version number of the SI or the SIB. After receiving the request message, the network side may selectively send the system information to the UE according to the version of the system information stored by the UE. The stored system information of the version to be updated is used to send the system information to the UE. For the system information of the version that has been stored for use, the network side notifies the UE that the used version is about to be updated.
(1)UE侧发送获取***信息请求消息给网络侧，该请求消息中可以携带如下一个或多个：(1) The UE side sends a system information request message to the network side, and the request message may carry one or more of the following:
-当前存储的***信息的版本信息，例如area ID和/或value tag，该版本信息可以包含全部SIB的版本信息或者部分SIB的版本信息，例如UE请求的SIB的版本信息。其中包含的版本信息可以是UE请求SIB的所有存储的版本信息，也可以是除去当前使用版本的其他版本的存储信息。- version information of the currently stored system information, such as area ID and/or value tag, the version information may include version information of all SIBs or version information of a part of SIBs, such as version information of SIBs requested by the UE. The version information included therein may be all stored version information of the UE requesting the SIB, or may be storage information of other versions except the currently used version.
-请求的SIB ID。其中MIB和SIB1可以显式的通过请求消息携带对应的ID请求网络侧发送对应***消息，也可以隐式请求，即总是请求MIB和/或SIB1。- The requested SIB ID. The MIB and the SIB1 may explicitly request the network side to send the corresponding system message by using the corresponding ID, or may implicitly request, that is, the MIB and/or the SIB1 are always requested.
-显式或隐式的***信息请求指示。- Explicit or implicit system information request indication.
(2)网络侧发送通过专用信令发送***信息给UE，其中该专用信令可以包含如下一个或多个：(2) The network side sends system information to the UE by using dedicated signaling, where the dedicated signaling may include one or more of the following:
-***信息配置；- system information configuration;
-***信息版本信息，例如area ID和/或value tag；- system information version information, such as area ID and / or value tag;
其中***信息配置可以为基于当前应用的***信息的delta配置方式进行配置，即只包含更新的MIB或SIB或SI中更新的IE。对于缺省的IE网络侧和UE认为该IE保持原配置。The system information configuration may be configured according to the delta configuration mode of the system information of the current application, that is, only the updated MIB or the updated IE in the SIB or SI. For the default IE network side and the UE considers the IE to remain in the original configuration.
也可以是full配置方式，即包含完整的MIB或SIB或SI配置的所有的IE。It can also be a full configuration, that is, all IEs that contain a complete MIB or SIB or SI configuration.
其中包含的SIB或SI可以是部分SIB或SI，例如更新的SIB或SI；或必须的SIB或SI，例如SIB1；或所有SIB或SI。网络侧接收到***信息请求消息后，可以根据请求消息发送MIB和/或SIB1，或基于MIB或SIB1是否发生变化而决定是否发送MIB或SIB1，或总是发送MIB和/或SIB1。The SIB or SI included therein may be a partial SIB or SI, such as an updated SIB or SI; or a necessary SIB or SI, such as SIB1; or all SIBs or SIs. After receiving the system information request message, the network side may send the MIB and/or SIB1 according to the request message, or decide whether to send the MIB or SIB1 based on whether the MIB or the SIB1 changes, or always send the MIB and/or SIB1.
其中***信息版本信息可以是UE存储的所有SIB对应的版本信息，或者部分SIB对应的版本信息。该版本信息可以只包含value tag，或包含value tag以及area ID。The system information version information may be version information corresponding to all SIBs stored by the UE, or version information corresponding to a part of the SIB. The version information can contain only the value tag, or the value tag and the area ID.
(3)UE可以在接收到***信息更新paging DCI后发起请求，或者在没有成功接收广播***信息时发起请求，或请求没有存储的***信息时(例如UE初始接入只获取了接入网络必须的***信息，但其他例如邻区的配置信息等并未获取，如果后续UE希望获得这些***信息，则可以向网络请求)，或包含有特殊业务的UE，例如URLLC，向网络侧请求，或其他需要获取***信息的场景，不限于以上场景。(3) The UE may initiate a request after receiving the system information update paging DCI, or initiate a request when the broadcast system information is not successfully received, or request system information that is not stored (eg, the initial access of the UE only acquires the access network) System information, but other configuration information such as neighboring areas are not obtained, if the subsequent UE wishes to obtain the system information, it may request to the network, or a UE containing a special service, such as URLLC, requests to the network side, or Other scenarios in which system information needs to be obtained are not limited to the above scenarios.
(4)UE接收到网络侧通过专用信令发送的***信息后该***信息立即生效或在下一个修改周期生效。(4) The system information is valid immediately after the UE receives the system information sent by the network side through dedicated signaling or takes effect in the next modification period.
例如，对于PWS消息，则UE接收后应立即生效。对于其他***消息，则可结合发送paging DCI的时间判断生效时间(例如接收到网络发送的***信息与paging DCI同***信息修改周期则在下一个周期生效，如果不是同周期则立即生效)，或根据UE请求的场景而选择立即生效，例如UE请求缺乏的SIB消息，或网络不发送paging DCI，UE接收后则立即生效。For example, for a PWS message, the UE should take effect immediately after receiving it. For other system messages, it can be combined with the time when the paging DCI is sent to determine the effective time (for example, the system information sent by the network and the paging DCI are updated in the next cycle, if they are not in the same cycle, or immediately), or according to The UE requests the scenario to take effect immediately, for example, the UE requests a lack of SIB messages, or the network does not send a paging DCI, and the UE takes effect immediately after receiving.

(3)网络侧接收到UE发送的***信息请求消息，组装对应的***信息通过专用信令发送给UE。该消息可以按照full配置的方式或delta配置的方式携带对应的消息和/或对应的版本信息。如以上情况一中示例三和示例四所述。(3) The network side receives the system information request message sent by the UE, and the corresponding system information is sent to the UE through dedicated signaling. The message may carry the corresponding message and/or the corresponding version information in a full configuration manner or a delta configuration manner. As described in Example 3 and Example 4 of the above case 1.
(4)UE接收到网络侧发送的携带***信息的专用信令后，按照delta配置的方式或full配置的方式存储***信息，并在相应的时刻将***信息生效。如以上情况一中示例一和示例二所述。(4) After receiving the dedicated signaling carrying the system information sent by the network side, the UE stores the system information according to the method of delta configuration or full configuration, and validates the system information at the corresponding moment. As described in Example 1 and Example 2 of the above case 1.
示例二：UE发送存储的***信息版本信息请求网络侧发送***信息；Example 2: The UE sends the stored system information version information to request the network side to send system information.
(1)UE决定向网络侧请求更新的***信息。(1) The UE decides to request updated system information from the network side.
(2)UE组装***信息请求通知消息，其中该消息可以携带当前UE存储的全部SIB的所有版本信息或除当前使用的版本以外的所有版本信息；或者携带UE请求的SIB存储的对应的版本信息或除当前使用的版本以外的所有版本信息。例如当前SIB2存储版本1和版本2，当前SIB3存储版本4，而当前使用版本：SIB2使用版本1，SIB3使用版本4，则UE可以携带SIB2版本2，而SIB3无需携带对应版本，或者提供SIB2存储版本1和版本2，SIB3存储版本4。(2) The UE assembles a system information request notification message, where the message may carry all version information of all SIBs stored by the current UE or all version information except the currently used version; or carry corresponding version information of the SIB storage requested by the UE. Or all version information except the version currently in use. For example, the current SIB2 stores the version 1 and the version 2, the current SIB3 stores the version 4, and the current version: the SIB2 uses the version 1 and the SIB3 uses the version 4. The UE can carry the SIB2 version 2, and the SIB3 does not need to carry the corresponding version, or provides the SIB2 storage. Version 1 and Version 2, SIB3 stores version 4.
(3)网络侧接收到UE发送的***信息请求消息，组装对应的***信息通过专用信令发送给UE。该消息中携带更新SIB使用的版本信息通知，以通 知UE使用对应版本的***信息，和/或某些***信息配置。对于即将更新使用的SIB的版本其中UE并没有存储该版本配置信息，网络侧按照delta配置方式或full配置方式提供对应的SIB或SI的配置信息，如以上情况一中示例三和示例四所述。例如更新SIB2使用版本2，SIB3使用版本1，则该专用信令消息中需携带SIB3的版本1的***消息，而无需携带SIB2的***信息。对于MIB与SIB1，网络侧可以使用full配置或delta配置的方式将对应的***信息配置组装到该消息中给UE。携带通知UE使用的SIB的新版本信息，如上例需携带通知SIB2使用版本2，SIB3使用版本1的通知信息。对于并没有改变的SIB，网络侧可以携带该SIB的版本信息也可以不携带而默认继续使用以前的版本信息。(3) The network side receives the system information request message sent by the UE, and the corresponding system information is sent to the UE through dedicated signaling. The message carries a version information notification used by the update SIB to notify the UE to use the corresponding version of the system information, and/or some system information configuration. For the version of the SIB to be updated, in which the UE does not store the version configuration information, the network side provides the configuration information of the corresponding SIB or SI according to the delta configuration mode or the full configuration mode, as described in Example 3 and Example 4 in the above case 1. . For example, if the update SIB2 uses version 2 and the SIB3 uses version 1, the dedicated signaling message needs to carry the system message of version 1 of SIB3 without carrying the system information of SIB2. For the MIB and the SIB1, the network side can use the full configuration or the delta configuration to assemble the corresponding system information configuration into the message to the UE. The new version information of the SIB that is used to notify the UE is used to carry the notification SIB2 to use version 2 and the SIB3 to use the version 1 notification information. For the SIB that has not changed, the network side may carry the version information of the SIB or may not carry it and continue to use the previous version information by default.
(4)UE接收到网络侧发送的携带***信息的专用信令后，按照delta配置的方式或full配置的方式存储***信息，并存储对应的版本信息，并在相应的时刻将该消息中通知的版本的***信息生效。如以上情况一中示例三和示例四所述。(4) After receiving the dedicated signaling carrying the system information sent by the network side, the UE stores the system information according to the method of delta configuration or full configuration, and stores the corresponding version information, and notifies the message at the corresponding time. The version of the system information is in effect. As described in Example 3 and Example 4 of the above case 1.

(1)UE决定向网络侧请求更新的***信息。(1) The UE decides to request updated system information from the network side.
(2)UE组装***信息请求通知消息，其中该消息可以携带UE请求的SIB ID，其中对于MIB和SIB1可以携带对应的ID或不携带对应ID默认为总是请求MIB或SIB；或者同时携带请求SIB对应的UE存储的所有版本信息或除当前使用的版本以外的所有版本信息。例如请求SIB2和SIB3，当前SIB2存储版本1和版本2，当前SIB3存储版本4，而当前使用版本:SIB2使用版本1,SIB3使用版本4，则UE可以携带SIB2版本2，而SIB3无需携带对应版本，或者提供SIB2存储版本1和版本2，SIB3存储版本4。(2) The UE assembles a system information request notification message, where the message may carry the SIB ID requested by the UE, where the MIB and the SIB1 may carry the corresponding ID or do not carry the corresponding ID, and default to always request the MIB or the SIB; or carry the request at the same time. All version information stored by the UE corresponding to the SIB or all version information except the currently used version. For example, SIB2 and SIB3 are requested, the current SIB2 stores version 1 and version 2, the current SIB3 stores version 4, and the current version: SIB2 uses version 1, and SIB3 uses version 4, the UE can carry SIB2 version 2, and SIB3 does not need to carry the corresponding version. , or provide SIB2 storage version 1 and version 2, SIB3 storage version 4.

The message carries the configuration message of the requested SIB or the SI, and the message may also carry the version information of the corresponding SIB, or the version message used by the message in the message, and the configuration message of the SIB or SI of the SIB version not stored by the UE. . The configuration message of the foregoing SIB or SI or MIB may be provided to the UE according to a delta configuration or a full configuration manner, as described in Example 3 and Example 4 in the foregoing case 1. For example, if the request message carries the version information that the UE requests the SIB to store, the version of the SIB that has been stored by the UE for the updated SIB has not yet stored the configuration information of the SIB, and the network provides the configuration information of the SIB, and for the updated SIB. In the version used, the UE has stored the configuration information of the SIB of the version, and the network side does not need to provide detailed configuration information of the SIB, and only needs to notify the UE to use the corresponding version. For example, if the update SIB2 uses version 2 and the SIB3 uses version 1, the dedicated signaling message needs to carry the system message of version 1 of SIB3 without carrying the system information of SIB2. It is required to carry the notification SIB2 using version 2, and SIB3 uses the version 1 notification information. For the SIB that has not changed, the network side may carry the version information of the SIB or may not carry it and continue to use the previous version information by default.
(4)UE接收到网络侧发送的携带***信息的专用信令后，按照delta配置的方式或full配置的方式存储***信息，并存储对应的版本信息，并在相应的时刻将该消息中通知的版本的***信息生效，如以上情况一示例三和示例四所述。(4) After receiving the dedicated signaling carrying the system information sent by the network side, the UE stores the system information according to the method of delta configuration or full configuration, and stores the corresponding version information, and notifies the message at the corresponding time. The version of the system information is valid, as described in Example 3 and Example 4 above.
