图1示出了根据本发明实施例的系统信息的传输方法的示意性流程图。图1所示的方法包括：
110，终端通过专用控制信令向网络侧设备请求终端需要使用的系统信息。
具体地，上述系统信息可以包括主信息块(Master Information Block，MIB)和多个系统信息块(System Information Block，SIB)。其中，MIB可以携带接入LTE最基本的信息，例如，系统帧号(System Frame Number，SFN)使终端获得系统的时间信息、下行系统带宽、PHICH配置信息；SIB1可以携带小区选择与驻留相关的信息与其他系统信息块的调度信息；SIB2携带小区的接入限制信息、公共信道参数，多播/组播单频网络(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)子帧的配置信息；SIB3可以携带小区重选相关信息，主要关于服务小区重选参数以及同频小区重选参数；SIB4可以携带同频小区重选信息，例如，同频白/黑名 单小区列表；SIB5可以携带异频小区重选信息，例如，异频邻小区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可以携带异系统小区重选信息，例如，通用陆地无线接入网络(Universal Terrestrial Radio Access Network，UTRAN)邻频频点列表以及每个频点的重选参数、异频黑名单小区列表；SIB7可以携带异系统小区重选信息，例如，全球移动通信系统/增强型数据速率GSM演进技术的无线接入网(Global System for Mobile Communication/Enhanced Data Rate for GSM Evolution Radio Access Network，GERAN)中邻频频点列表以及每个频点的重选参数；SIB8可以携带异系统小区重选信息，例如，基于码分多址2000(Code Division Multiple Access 2000，CDMA2000)的邻区列表。

具体地，终端可以在专用控制信令中携带终端需要使用的系统信息的标识，该系统信息的标识可以用于指示系统信息的类型和/或系统信息。
应理解，上述系统信息的标识可以由网络侧设备根据比特映射(bitmap)的方式生成，再由网络侧设备将生成的系统信息的标识发送至终端；上述系统信息的标识还可以直接由终端生成，并由终端将生成的系统信息的标识发送指网络侧设备，本发明对系统信息的标识的生成方式不做具体限定。
120，所述终端接收所述系统信息。
本发明实施例中，终端能够基于自身的需求，通过专用控制信令向网络侧设备请求终端需要使用的系统信息，以节省传输系统信息时所使用的传输资源，避免了现有技术中，基站通过广播的方式传输系统信息而引起的传输资源的浪费。
