在3G系统中,系统消息承载了很多小区的配置信息及接入网的相关参数。增加对系统消息内容的了解,有助于快速查找关心的无线网络参数。

下面就RRC 25.332协议中关于系统消息的描述进行了概括性的总结,不足之处请包涵。

System information block type 1
承载NAS层系统信息:UE在空闲态与连接态所用的计时器、计数器。

System information block type 2
承载URA标识信息。

System information block type 3
承载空闲模式下UE进行小区选择与小区重选相关的参数信息。

System information block type 4

System information block type 13.4
承载ANSI-41系统全局重定向服务信息。

System information block type 14
承载公共专用物理信道上行开环功控的参数信息。该消息仅用于3.84 Mcps TDD and 7.68 Mcps TDD。

[SIB15在现网中没有实现,可以不关注.]
System information block type 15
Contained information useful for UE-based or UE-assisted positioning methods.

System information block type 15bis
Contained information useful for UE-based or UE-assisted positioning methods. The content of this SIB is common to all GANSS.

System information block type 15.1
Contained information useful for UE positioning DGPS Corrections. The DGPS Corrections message contents are based on a Type-1 message of DGPS specified in [13].

System information block type 15.1bis
Contained information useful for UE positioning DGANSS Corrections. The DGANSS Corrections message contents are based on a Type-1 message of DGANSS specified in [13]. The content of this SIB is GNSS specific.

System information block type 15.2
Contained information useful for GPS Navigation Model. These IE fields are based on information extracted from the subframes 1 to 3 of the GPS navigation message [12].

System information block type 15.2bis
Contained information useful for GANSS Navigation Model. The content of this SIB is GNSS specific.

System information block type 15.2ter
Contained information useful for GANSS Navigation Model. The content of this SIB is GNSS specific.

System information block type 15.3
Contained information useful for ionospheric delay, UTC offset, and Almanac. These IEs contain information extracted from the subframes 4 and 5 of the GPS navigation message, [12].

System information block type 15.3bis
Contained information useful for GANSS time model, UTC offset and Almanac, as well as auxiliary information. The content of this SIB is GNSS specific.

System information block type 15.4
Contained ciphering information for System Information Block type 15.5 and information useful for OTDOA UE-assisted Positioning method.

System information block type 15.5
Contained information useful for OTDOA UE-based Positioning method.

System information block type 15.6
Contained information useful for acquisition of GANSS signals. The content of this SIB is GNSS specific.

System information block type 15.7
Contained data bits which can be used for data wipe-off. The content of this SIB is GNSS specific.

System information block type 15.8
Contained ciphering information and real-time integrity information. The content of this SIB is GNSS specific.

System information block type 16
承载异系统切换的无线承载、传输信道及物理信道参数,所有信息UE在切换其间会在内部保存。

System information block type 17
承载连接模式下共享物理信道配置快速改变参数信息,仅用于TDD。

System Information Block type 18
承载邻小区的PLMN标识,用于空闲态与连接态。

System information block type 19
承载小区的异系统频率及切换优先级信息。

System information block type20
承载HNB[家庭节点]名称信息。

   至此,3G系统中的SIB信息已完全进行了说明。至于MIB信息与调度信息块,因为主要用于控制SIB,故这里没有进行阐述,感兴趣的读者可以参考3GPP 25.331 RRC协议规范。
