本公开涉及通信技术领域，尤其涉及一种***信息传输方法、用户终端和网络侧设备。
背景技术
无线通信***的***信息(SI，System Information)主要分为主信息块(MIB，Master Information Block)和多个***信息块(SIBs，System Information Blocks)。其中，***信息块可以包括SIB1～SIB20这些***信息。在实际应用中，很多场景是需要广播***信息的，例如：在用户终端(UE)新接入一个小区或广播消息发生改变时，都会广播***信息。目前每次广播都是广播所有***信息，即包括MIB、SIB1和SI这些***信息，其中SI包含SIB2～SIB20，当然，还可能继续扩展。由于目前无线通信***中***信息都是周期地广播的，且随着无线通信***业务多样化和终端类型不断演进，***信息的内容会越来越多，那么***信息的开销占用会越来越大。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1为本公开实施例提供的网络结构示意图。如图1所示，该网络结构包括一个或多个用户终端(UE，User Equipment)11和网络侧设备12。附图中以一个用户终端11进行举例示意。用户终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定用户终端11的具体类型。用户终端11可以与网络侧设备12建立通信。附图中的网络可以表示用户终端11与网络侧设备12无线建立通信，网络侧设备12可以是基站，基站可以是宏站，如长期演进(LTE，Long Term Evolution)的eNB(演进的节点B，Evolved Node B)、第五代移动通信技术5G NR(New RAT)NB(Node B)等；基站还可以是小站，如低功率节点(LPN：low power node)微微(pico)、毫微微(femto)等小站，或者可以是接入点(AP，access point)。网络侧设备12还可以是由中央单元(CU，central unit)和其管理和控制的多个传输接收点(TRP，Transmission Reception Point)共同组成的网络节点。另外，一个基站下有一个或多个小区(例如：不同的频点或扇区***)。需要说明的是，在本公开实施例中并不限定网络侧设备12的具体类型。
参见图2，本公开实施例提供一种***信息传输方法。如图2所示，该***信息传输方法包括以下步骤201和步骤202。
步骤201：用户终端获取网络侧设备的按需的***信息(on-demand SI)的广播周期信息。
步骤202：所述用户终端根据所述广播周期信息获取所述网络侧设备发 送的按需的***信息。
本公开实施例中，网络侧设备的按需的***信息可以是网络侧设备包括的***信息中的部分***信息，或者网络侧设备的按需的***信息可以是网络侧设备中除周期广播的***信息(periodic broadcast SI)之外的***信息。而周期广播的***信息(periodic broadcast SI)可以是网络侧设备的***信息中需要周期广播的***信息，例如：除按需的***信息之外的***信息，或者用户终端驻留到小区并接入驻留小区的***信息，如MIB、SIB1和SIB2中的全部或部分内容；或者用户终端(UE)驻留到小区并接入驻留小区必要的***信息等等。另外，按需的***信息(on-demand SI)也可以理解为通过按需的方式进行传输的***信息。
另外，上述网络侧设备的按需的***信息的广播周期信息可以是用于描述或者表示上述网络侧设备的按需的***信息的广播周期的信息，即用户终端通过该广播周期信息可以确定上述网络侧设备的按需的***信息的广播周期。其中，网络侧设备根据该广播周期广播按需的***信息。需要说明的是，网络侧设备并不是在每个按需的***信息的广播周期都需要广播按需的***信息，例如：在特定广播周期内没有用户终端需要按需的***信息，而网络侧设备在该广播周期内可以不广播按需的***信息。另外，网络侧设备每次广播的按需的***信息可以不相同，或者部分相同或者全部相同，且每次广播的按需的***信息可以是网络侧设备的按需的***信息中的部分或者全部。例如：在一广播周期内特定用户终端需要SIB3和SIB4，则网络侧设备在该广播周期内可以只广播SIB3和SIB4。另外，按需的***信息(on-demand SI)的广播周期可以理解为，网络侧设备每间隔该周期会有一个传输机会，按需的***信息可能在该传输机会上广播发送，或者可能在一些传输机会上不会广播发送。
另外，需要说明的是，步骤201获取的广播周期信息可以是接收网络侧设备周期发送的，或者用户终端提前获取的，例如网络侧设备预先给用户终端配置的。
当用户终端获取到上述广播周期信息后，就可以确定网络侧设备按需的***信息的周期，从而可以在这些周期获取所述网络侧设备发送的按需的系 统信息。
需要说明的是，本公开实施例中，并不限定***信息是MIB，以及SIB1～SIB20。***信息还可以是SIBn，其中，n为大于20的整数，或者***信息还可以是适应未来无线通信***的发展扩展的***信息。其中，SIB1可以包括广播小区接入与小区选择的相关参数以及SI消息的调度信息，可以包含了一个或多个SIB2～13；SIB2可以包括小区内所有UE共用的无线参数配置，其它无线参数基本配置；SIB3可以包括小区重选信息，主要关于服务小区重选参数以及同频小区重选参数；SIB4可以包括同频邻区列表以及每个邻区的重选参数、同频白/黑名单小区列表；SIB5可以包括异频相邻频点列表以及每个频点的重选参数、异频相邻小区列表以及每个邻区的重选参数、异频黑名单小区列表。SIB6可以包括通用陆地无线接入频分双工(UMTS Terrestrial Radio Access-Frequency Division Duplexing，UTRAFDD)邻频频点列表以及每个频点的重选参数、UTRA TDD邻频频点列表以及每个频点的重选参数；SIB7可以包括全球移动通信***(GSM)和增强型数据速率GSM演进技术(EDGE)无线接入网GERAN(GSM EDGE Radio Access Network，GERAN)邻频频点列表以及每个频点的重选参数；SIB8可以包括码分多址(CDMA)2000的预注册信息、CDMA2000邻频频段列表和每个频段的重选参数、CDMA2000邻频频段的邻区列表；SIB9可以包括家庭基站(Home eNodeB)的名称；SIB10可以包括地震海啸报警***(Earthquake and Tsunami Warning System，ETWS)主通知(primary notification)；SIB11可以包括ETWS辅通知(secondary notification)；SIB12可以包括商业移动警报服务(Commercial Mobile Alert Service，CMAS)通知(CMAS notification)；SIB 13可以包括获取跟一个或多个多播广播单频网络(Multicast Broadcast Single Frequency Network，MBSFN区域相关的多媒体广播组播功能(Multimedia Broadcast Multicast Service，MBMS)控制信息的信息。SIB14～SIB20各有其针对的特性，不再一一描述。
另外，需要说明的是，步骤202获取的按需的***信息可以包括上述用户终端需要的全部或者部分按需的***信息，或者步骤202获取的按需的***信息不包括上述用户终端需要的***信息，例如：上述用户终端需要的按 需的***信息是SIB3和SIB4，而网络侧设备发送的按需的***信息可能是SIB3和SIB4，或者SIB3和SIB5，或者SIB6、SIB7、SIB8和SIB9等等。且当用户终端接收到的按需的***信息不包括用户终端需要的***信息或者只包括上述用户终端需要的部分***信息时，用户终端可以执行下一次按需的***信息获取流程。
通过上述步骤可以实现用户终端根据上述广播周期获取网络侧设备发送的按需的***信息。由于不是每次都广播全部的***信息，从而可以达到节省传输资源的目的。
可选的，上述用户终端获取网络侧设备的按需的***信息的广播周期信息(步骤201)包括：所述用户终端接收所述网络侧设备周期广播的***信息，所述周期广播的***信息包括所述按需的***信息的广播周期信息。
在该实施方式中，可以实现用户终端在网络侧设备周期广播的***信息中获取网络侧设备的按需的***信息的广播周期信息。另外，按需的***信息的广播周期可以比周期广播的***信息的广播周期要长，例如：按需的***信息的广播周期可以是周期广播的***信息的广播周期的整数倍。另外，上述周期广播的***信息可以是只包括按需的***信息的广播周期的***信息。当然，在一些场景中，上述周期广播的***信息还可以包括其他需要周期广播的***信息，例如，MIB、SIB1和SIB2。
可选的，上述周期广播的***信息还包括所述按需的***信息的广播指示信息。广播指示信息用于指示所述网络侧设备在下一个按需的***信息的广播周期中按需的***信息的发送情况。例如：在网络侧设备在下一个按需的***信息的广播周期中会广播发送按需的***信息，或者网络侧设备在下一个按需的***信息的广播周期中不会广播发送按需的***信息，或者网络侧设备在下一个按需的***信息的广播周期中发送了哪些按需的***信息等等。从而在用户终端接收到上述广播指示信息后，就可以在步骤202中根据上述广播周期和广播指示信息获取所述网络侧设备发送的按需的***。
可选的，所述广播指示信息用于指示下一个按需的***信息的广播周期到达时是否有按需的***信息广播发送。
其中，上述下一个按需的***信息的广播周期可以是离当前时间最近的 所述网络侧设备的一个按需的***信息的广播周期。其中，上述广播指示信息可以通过特定比特进行指示，例如：用1比特指示，1表示下一个按需的***信息的广播周期到达时有按需的***信息广播，0表示没有；或者出现时用真(true)表示下一个按需的***信息的广播周期到达时有按需的***信息广播，不出现则无该指示。
该实施方式中，通过上述广播指示信息可以节约终端的功耗，例如：指示在下一个广播周期不广播按需的***信息时，从而用户终端就不需要执行获取的操作，以节约功耗。
可选的，上述广播指示信息用于指示下一个按需的***信息的广播周期到达时哪些按需的***信息会广播发送。
该实施方式中，通过上述广播指示信息可以实现指示下一个按需的***信息的广播周期到达时，上述网络侧设备会广播发送哪些按需的***信息。从而用户终端就可以根据该广播指示信息执行获取的动作，例如：指示的按需的***信息不包括用户终端需要的按需的***信息，而可以不获取，以节约终端的功耗；如果指示的按需的***信息包括用户终端需要的按需的***信息，则在下一个广播周期获取网络侧设备广播的按需的***信息。
可选的，上述广播指示信息以索引列表或者位图的方式指示下一个按需的***信息的广播周期到达时哪些按需的***信息会广播发送。
该实施方式中，上述广播指示信息可以理解为按需的***信息列表，以指示下一个按需的***信息广播周期到达时哪些按需的***信息进行广播发送。可以是索引列表(index list)，还可以是指示***信息索引(SIB index)的位图(bitmap)，其中bitmap指示SIB1～SIBn(n为正整数，例如n＝20)是否包含在按需的***信息广播发送中。如果包含，那么用1表示；否则，用0表示。
可选的，上述广播周期信息包括：***信息周期、起始点和***信息时间窗。其中，上述***信息周期可以理解为上述网络侧设备的按需的***信息的广播周期，即网络侧设备广播发送按需的***信息的传输机会的时间间隔。可选的，上述***信息周期可以通过无线帧数来表示，例如：{rf8，rf16，rf32，rf64，rf128，rf256，rf512}。从而用户终端可以通过上述***信息周期确定 上述网络侧设备的按需的***信息的广播周期。
另外，上述起始点可以是每个***信息周期的起始点，即网络侧设备广播发送按需的***信息的传输机会的每个时间间隔的起始点。当然，上述起始点可以理解为起始位置。可选地，起始点可以通过无线帧的子帧信息来表示，例如：起始点可以每个***信息周期对应的无线帧中的第n个子帧，例如：n为2、3、4、5、或者6等等。用户终端通过上述起始点就可以确定各广播周期按需的***信息的起始点，从而在该起始点就可以进行***信息的接收。
上述***信息时间窗可以理解为在有按需的***信息广播发送的***信息周期到达时，用户终端接收按需的***信息的时间窗长度。例如：下一个按需的***信息广播周期有按需的***信息广播发送，那么，在该广播周期到达时，用户终端就可以在该***信息时间窗接收按需的***信息。
需要说明的是，上述***信息时间窗和上述起始点并不限定每个广播周期信息中都携带，但可以是每个广播周期信息中都携带上述***信息时间窗和上述起始点。因为在一些场景内或者在一定时间内上述***信息时间窗和上述起始点可以是固定的，从而可以提前给用户终端配置***信息时间窗和上述起始点；或者只有特定时间内的第一个广播周期信息中携带***信息周期、起始点和***信息时间窗，而在接下来的一个或者多个广播周期信息中可以只携带***信息周期，而可以不携带起始点和***信息时间窗。另外，上述***信息周期、起始点和***信息时间窗都可以是由网络侧设备配置的。
可选的，上述方法还包括：所述用户终端向所述网络侧设备发送按需的***信息请求消息(on-demand SI request message)，所述按需的***信息请求消息用于请求所述用户终端需要的按需的***信息。
所述用户终端根据所述广播周期信息获取所述网络侧设备发送的按需的***信息(上述步骤202)包括：所述用户终端在下一个按需的***信息的广播周期到达时，接收所述网络侧设备发送的按需的***信息响应消息(on-demand SI response message)。
该实施方式中，可以实现用户终端向网络侧设备发送上述***信息请求消息，以请求用户终端需要的***信息。例如：上述用户终端需要的按需的 ***信息是SIB3和SIB4，则用户终端可以向网络侧设备发送SIB3和SIB4对应的***信息请求消息。其中，上述发送***信息请求消息的步骤可以在步骤201之后执行，当然，在一些场景中还可以是在步骤201之前执行的。
在网络侧设备接收到上述***信息请求消息后，就可以根据该***信息请求消息在下一个按需的***信息的广播周期发送按需的***信息。或者可以是网络侧设备根据用户终端发送的按需的***信息请求消息以及自己可以提供的按需的***信息，在下一个按需的***信息广播周期到达时广播发送按需的***信息响应消息，其中包含可以提供的全部或部分用户终端所需的按需的***信息。
该实施方式中，可以实现根据用户终端发送的按需的***信息请求消息进行按需的***信息发送，从而可以避免广播用户终端不需要的按需的***信息，以避免传输资源浪费。当然，上述用户终端也可以发送上述按需的***信息请求消息，例如：根据上述广播指示信息获知网络侧设备在下一个按需的***信息广播周期会发送按需的***信息，则可以直接在下一个广播周期获取，可能获取的按需的***信息包括用户终端需要的，如果不包括用户终端需要的，用户终端则可以再发送上述按需的***信息请求消息。或者用户终端根据上述广播指示信息获知网络侧设备在下一个按需的***信息广播周期广播的按需的***信息会包括用户终端需要的***信息，则可以直接在下一个广播周期获取，从而不需要发送请求消息。
另外，网络侧设备可以使用无线网络临时标识(SI-RNTI，system information-radio network temporary identifier)(如OD-SI-RNTI)加扰的物理下行控制信道(PDCCH，Physical Downlink Control Channel)调度按需的***信息响应消息，各用户终端可以通过SI-RNTI进行寻址。且对于广播方式发送按需的***信息响应消息，网络侧可以重复发送按需的***信息，用户终端通过混合自动重传请求(HARQ，Hybrid Automatic Repeat reQuest)重传合并(没有ACK/NACK反馈)来提高***信息接收性能。
可选的，上述按需的***信息响应消息包括所述用户终端需要的全部或者部分按需的***信息，或者所述按需的***信息响应消息不包括所述用户终端需要的***信息；其中，所述按需的***信息响应消息还包括其他用户 终端需要的全部或者部分的按需的***信息，或者不包括其他用户终端需要的按需的***信息。
例如：上述按需的***信息响应消息包括所述用户终端需要的全部或者部分按需的***信息，或者所述按需的***信息响应消息不包括所述用户终端需要的***信息；或者所述按需的***信息响应消息包括所述用户终端需要的全部按需的***信息，以及还包括其他用户终端需要的全部或者部分按需的***信息，或者不包括其他用户终端需要的***信息；或者所述按需的***信息响应消息包括所述用户终端需要的部分按需的***信息，以及还包括其他用户终端需要的全部或者部分按需的***信息，或者不包括其他用户终端需要的***信息；或者所述按需的***信息响应消息不包括所述用户终端需要的按需的***信息，但包括其他用户终端需要的全部或者部分按需的***信息，或者也不包括其他用户终端需要的***信息。
其中，所述按需的***信息响应消息不包括所述用户终端需要的按需的***信息，则确定网络侧无法提供自己所需的***信息。另外，该实施方式中，网络侧设备广播多个用户终端需要的按需的***信息，即网络侧终端将可以提供的多个用户终端所需的按需的***信息进行合并，并在下一个按需的***信息广播周期到达时进行广播发送，以节省传输资源。例如，UE1请求的***信息为{SIB3，SIB4}，UE2请求的***信息为{SIB5，SIB6}，UE3请求的***信息为{SIB3，SIB4，SIB5，SIB6}，网络侧设备根据3个UE发送的按需的***信息请求消息，结合自己可提供的按需的***信息，在下一个按需的***信息广播周期到达时广播包含SIB3、SIB4、SIB5和SIB6的***信息，当然，也可以可能只有SIB3、SIB4、SIB5和SIB6中部分，以及还可以包括其他的***信息。
可选的，上述按需的***信息响应消息包括***信息表格索引，所述用户终端根据所述广播周期信息获取所述网络侧设备发送的按需的***信息(上述步骤202)还包括：所述用户终端从已保存的***信息表格中查找与所述***信息表格索引对应的按需的***信息；其中，所述与所述***信息表格索引对应的按需的***信息包括所述用户终端需要的全部或者部分按需的***信息，或者不包括所述用户终端需要的***信息；且所述与所述*** 信息表格索引对应的按需的***信息还包括其他用户终端需要的全部或者部分的按需的***信息，或者所述与所述***信息表格索引对应的按需的***信息不包括其他用户终端需要的按需的***。
例如：所述与所述***信息表格索引对应的按需的***信息包括所述用户终端需要的全部或者部分按需的***信息，或者不包括所述用户终端需要的***信息；或者所述与所述***信息表格索引对应的按需的***信息包括所述用户终端需要的全部按需的***信息，以及还包括其他用户终端需要的全部或者部分按需的***信息，或者不包括其他用户终端需要的***信息；或者所述与所述***信息表格索引对应的按需的***信息包括所述用户终端需要的部分按需的***信息，以及还包括其他用户终端需要的全部或者部分按需的***信息，或者不包括其他用户终端需要的***信息；或者所述与所述***信息表格索引对应的按需的***信息不包括所述用户终端需要的按需的***信息，但包括其他用户终端需要的全部或者部分按需的***信息，或者也不包括其他用户终端需要的***信息。
该实施方式中，网络侧广播的按需的***信息可以是***信息表格索引(SI table index)，以节约传输开销。另外，***信息表格索引是针对已保存***信息表格(SI table)的用户终端的一种方式，用户终端收到***信息表格索引，可以查找***信息表格，找到对应的SIB内容。其中，用户终端已保存的***信息表格可以是预先配置的，还可以是用户终端预先接收网络侧设备发送的并保存的。
可选的，所述用户终端向所述网络侧设备发送按需的***信息请求消息，包括：若所述用户终端只接收到所述广播周期信息，则所述用户终端向所述网络侧设备发送按需的***信息请求消息；或者若所述用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时没有按需的***信息广播发送，则所述用户终端向所述网络侧设备发送按需的***信息请求消息；或者若所述用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时有按需的***信息广播发送，但所述用户终端在该广播周期中没有接收到所述用户终端需要的按需的***信息，则所述用户终端向所述网络侧设备发送按需的***信息请求消息；或者若所述用户终端接收到的 广播指示信息指示下一个按需的***信息的广播周期到达时广播发送的按需的***信息不包括所述用户终端需要的按需的***信息，则所述用户终端向所述网络侧设备发送按需的***信息请求消息。
该实施方式中，可以实现如果终端仅收到按需的***信息的广播周期，则向网络侧设备发送上述***信息请求消息，以避免在下在按需的***信息广播周期达到时，网络侧设备不广播按需的***信息的情况。还可以实现当用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时没有按需的***信息广播发送，例如：用户终端收到存在指示为0或者不出现存在指示，指示下一个按需的***信息广播周期到达时没有按需的***信息进行广播发送，则向网络侧设备发送上述***信息请求消息，以避免在下一个按需的***信息广播周期达到时，网络侧设备不广播按需的***信息的情况。还可以实现当用户终端接收到的广播指示信息指示下一个按需的***信息广播周期到达时有按需的***信息广播发送，在下一个按需的***信息广播周期接收的按需的***信息不包括用户终端需要的按需的***信息，其中，这里的不包括可以是不包括用户终端需要的任何按需的***信息，或者不包括用户终端需要的部分按需的***信息，即只包括部分。从而用户终端发送上述***信息请求消息。需要说明的是，该场景中，上述用户终端接收到上述按需的***信息响应消息的下一个按需的***信息的广播周期为步骤201接收到广播周期后的第二个按需的***信息广播周期，因为用户终端是在第一按需的***信息的广播周期到达时发现接收到的按需的***信息不包括用户终端需要的***信息。例如：如果用户终端收到存在指示为1或者true，指示下一个按需的***信息广播周期到达时有按需的***信息进行广播发送，那么该用户终端可以在下一个按需的***信息广播周期到达时，获取广播发送的按需的***信息。进一步的，该用户终端查看是否包含自己需要的***信息，如果包含，那么用户终端已获取所需的***信息；如果不包含，那么该用户终端向网络侧设备发送上述按需的***信息请求消息。还可以实现若所述用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时广播发送的按需的***信息不包括所述用户终端需要的按需的***信息，则向所述网络侧设备发送按需的***信息请求。例如：广播指示信 息下一个按需的***信息广播周期会广播SIB4、SIB5和SIB6，但用户终端需要的是SIB3和SIB4，则用户终端可以发送上述按需的***信息请求消息。例如：如果用户终端收到按需的***信息列表，指示下一个按需的***信息广播周期到达时哪些按需的***信息进行广播发送，那么该用户终端查看是否包含自己需要的***信息，如果包含，那么用户终端可以在下一个按需的***信息广播周期到达时，获取所需的***信息；如果不包含，那么该用户终端向网络侧设备发送上述按需的***信息请求消息。
可选的，上述用户终端向所述网络侧设备发送按需的***信息请求消息，包括：所述用户终端通过随机接入过程的Msg3向所述网络侧设备发送按需的***信息请求消息；或者所述用户终端通过无线资源控制RRC消息向所述网络侧设备发送按需的***信息请求消息；或者
所述用户终端通过媒体接入控制控制单元MAC CE向所述网络侧设备发送按需的***信息请求消息。
该实施方式中，空闲态/非激活用户终端通过随机接入过程进行按需的***信息请求消息发送。也就是在随机接入过程的Msg3中包含按需的***信息请求消息。以及连接态用户终端通过RRC消息或MAC CE进行按需的***信息请求消息发送。也就是说UE可以在RRC消息或MAC CE中包含按需的***信息请求消息，其中包含按需的***信息列表。其中，上述随机接入过程可以是LTE***中的随机接入过程。
可选的，上述***信息请求消息包括所述用户终端需要的按需的***信息的信息列表。
该实施方式中，可以实现按需的***信息的信息列表指示用户终端需要的按需的***信息，例如：当用户终端所需的***信息是SIB3和SIB4，那么用户终端发送的按需的***信息请求消息中包含的按需的***信息列表为{SIB3，SIB4}或{00110000000000000000}。
可选的，所述方法还包括：所述用户终端获取上行信号与按需的***信息的映射关系信息。所述用户终端向所述网络侧设备发送按需的***信息请求消息，包括：所述用户终端向所述网络侧设备发送上行信号，其中，所述上行信号与所述用户终端需要的按需的***信息存在映射关系。
该实施方式中，上述映射关系信息可以是从接收到周期广播的***信息中获取的，即网络侧设备发送的周期广播的***信息中包括上述映射关系信息，或者用户终端预先配置的，从而从本地获取上述映射关系信息。该实施方式中，可以通过发送上述上行信号，以告知网络侧设备用户终端需要的按需的***信息，而发送上行信号是基于现有流程实现的，从而可以减少通信流程，以及用户终端和网络侧设备的改进。当然，网络侧设备也是预先获取有上述映射关系信息。例如：空闲态/非激活用户终端通过上行信号过程进行按需的***信息请求消息发送。也就是用户终端发送上行信号(例如，Preamble前导码，Sync同步码等)，该上行信号与按需的***信息存在映射表。例如，Preamble1对应SIB3，Preamble2对应SIB4或Preamble3对应SIB3和SIB4。
可选的，上述用户终端根据所述广播周期获取所述网络侧设备发送的按需的***信息(上述步骤202)，包括：若所述广播指示信息指示下一个按需的***信息的广播周期到达时有按需的***信息广播发送，则所述用户终端在下一个按需的***信息的广播周期到达时接收所述网络侧设备广播发送的按需的***信息，其中：所述网络侧设备广播发送的按需的***信息包括所述用户终端需要的全部或者部分按需的***信息，或者不包括所述用户终端需要的***信息；且所述网络侧设备广播发送的按需的***信息还包括其他用户终端需要的全部或者部分的按需的***信息，或者不包括其他用户终端需要的按需的***信息。
例如：所述网络侧设备广播发送的按需的***信息包括所述用户终端需要的全部或者部分按需的***信息，或者不包括所述用户终端需要的***信息；或者所述网络侧设备广播发送的按需的***信息包括所述用户终端需要的全部按需的***信息，以及还包括其他用户终端需要的全部或者部分按需的***信息，或者不包括其他用户终端需要的***信息；或者所述网络侧设备广播发送的按需的***信息包括所述用户终端需要的部分按需的***信息，以及还包括其他用户终端需要的全部或者部分按需的***信息，或者不包括其他用户终端需要的***信息；或者所述网络侧设备广播发送的按需的***信息不包括所述用户终端需要的按需的***信息，但包括其他用户终端需要 的全部或者部分按需的***信息，或者也不包括其他用户终端需要的***信息。
该实施方式中，可以实现若广播指示信息指示下一个按需的***信息的广播周期到达时有按需的***信息广播发送，用户终端可以直接在下一个按需的***信息的广播周期到达时接收所述网络侧设备广播发送的按需的***信息。这里的广播指示信息指示下一个按需的***信息的广播周期到达时有按需的***信息广播发送，可以理解为广播指示信息通过指示下一个按需的***信息的广播周期到达时是否有按需的***信息广播的方式进行指示的。还可以是通过指示下一个按需的***信息的广播周期到达时广播发送的按需的***信息的方式指示下一个按需的***信息广播周期到达时有按需的***信息发送，例如：广播指示信息指示的下一个按需的***信息广播周期到达时广播发送的***信息中包括用户终端需要的***信息，则用户终端可以直接在下一个按需的***信息广播周期到达时接收所述网络侧设备广播发送的按需的***信息，从而不需要发送按需的***信息请求消息，以节约传输开销。
可选的，在所述用户终端向所述网络侧设备发送按需的***信息请求消息之后，所述方法还包括：若所述用户终端在下一个按需的***信息的广播周期没有接收到所述网络侧设备返回的反馈，则进行下一次的按需的***信息广播发送过程。
该实施方式中，可以实现用户终端在下一个按需的***信息广播周期到达时没有收到网络侧的反馈，认为请求按需的***信息失败，那么用户终端需要进行下一次的按需的***信息广播发送过程。
需要说明的是，本公开实施例中上述介绍的多种可选的实施方式之间可以相互结合实现，也可以单独实现，对此本公开实施例不作限定。
本公开实施例，用户终端获取网络侧设备的按需的***信息的广播周期；所述用户终端根据所述广播周期获取所述网络侧设备发送的按需的***信息。这样可以实现***信息按需发送，相比相关技术所有***信息都是周期广播，本公开实施例可以降低整个***信息的资源开销，提升***整体资源利用率。
参见图3，本公开实施例还提供一种***信息传输方法，如图3所示， 该***信息传输方法包括以下步骤301至步骤302。

可选的，所述网络侧设备接收所述用户终端发送的按需的***信息请求消息，包括：若所述用户终端只接收到所述广播周期信息，则所述网络侧设备接收所述用户终端发送的按需的***信息请求消息；或者若所述用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时没有按需的***信息广播发送，则所述网络侧设备接收所述用户终端发送的按需的***信息请求消息；或者若所述用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时有按需的***信息广播发送，但所述用户终端在该广播周期中没有接收到所述用户终端需要的按需的***信息，则所述网络侧设备接收所述用户终端发送的按需的***信息请求消息；或者若所述用户终端接收到的广播指示信息指示下一个按需的***信息的广播周期到达时广播发送的按需的***信息不包括所述用户终端需要的按需的***信息，则所述网络侧设备接收所述用户终端发送的按需的***信息请求消息。
