[44.018]Radio Resource Control (RRC) protocol(Release 5) ---- Scope篇

协议原文：

 

1 Scope The present document specifies the procedures used at the radio interface (Reference Point Um, see 3GPP TS 24.002) for Radio Resource (RR) management. Notation "Reserved sub-clause number" is used to indicate which sub-clauses of the specification were moved from this part of the standard to the other part when this standard was split between RAN and CN parts. When the notations for "further study" or "FS" or "FFS" are present in this specification they mean that the indicated text is not a normative portion of this standard. These procedures are defined in terms of messages exchanged over the control channels of the radio interface. The control channels are described in 3GPP TS 44.003. The structured functions and procedures of this protocol and the relationship with other layers and entities are described in general terms in 3GPP TS 24.007.

解释：

本协议文档描述的是2G的RRM中使用的过程，"Reserved sub-clause number" 表示文档中该章节号因标准的改动而已被移动到其他部分。当出现"further study"或"FS"或"FFS"的时候，表示指示的内容不属于本标准文档规定的部分。

本协议论述的这些过程是依据在无线接口控制信道中进行的交互消息来进行定义的，关于控制信道的描述可参见44.003协议。

本协议论述的结构功能和过程，以及和其他层与实体之间的关系在协议24.007中有定义。 

进一步说明：

1.本协议只是论述GSM的RRC过程，不包括3G内容。

2.本协议讲述了诸多过程，这些过程均属于控制面，而不涉及数据面的内容。

3.本协议只包括了空闲态到专用态（RR建立）、专用态到专用态（信道切换等）、专用态到空闲态（RR断链）的过程，而不包括初始为空闲态、过程结束仍为空闲态诸如小区重选、位置更新等过程。

4.协议45.002对控制信道进行了更为详细的论述，在阅读本协议即44.018协议前建议先阅读协议45.002。

 

 

协议原文：

1.1   Scope of the Technical Specification The procedures currently described in the present document are for radio resource management for circuit-switched and GPRS services. 3GPP TS 24.010 contains functional procedures for support of supplementary services. 3GPP TS 24.011 contains functional procedures for support of point-to-point short message services. 3GPP TS 44.012 contains functional description of short message - cell broadcast. 3GPP TS 44.060 contains procedures for radio link control and medium access control (RLC/MAC) of packet data physical channels. 3GPP TS 44.071 contains functional descriptions and procedures for support of location services. 3GPP TS 24.008 contains the procedures for CN protocols. NOTE:      "layer 3" includes the functions and protocols described in this Technical Specification. The terms "data link layer" and "layer 2" are used interchangeably to refer to the layer immediately below layer 3.

解释：

本文档描述的过程包括RRM中的电路交换业务和GPRS业务，即CS域和PS域业务均包含。

协议24.010包含支持增补业务（supplementary services）的过程。 

协议24.011包含支持点到点短消息（point-to-point short message）业务的过程。

协议24.012包含短消息-小区广播的描述。

协议44.060包含分组数据物理信道的无线链路控制（RLC）和媒介接入控制（MAC）的过程。

协议44.071包含支持定位业务的描述和过程。

协议24.008包含核心网协议的相关过程。

注意：“layer 3”（层3）包括本技术文档描述的功能和协议，层3的邻近底层则用术语“data link layer”（数据链路层）或“layer 2”（层2）来表述，在不同的语境中使用这两个术语中的其中一个。

进一步解释：

在学习44.018协议时，我们常需要参考其他协议，上述只是提到了一小部分。

  

协议原文：

1.2 Application to the interface structures The layer 3 procedures apply to the interface structures defined in 3GPP TS 44.003. They use the functions and services provided by layer 2 defined in 3GPP TS 44.005 and 3GPP TS 44.006. 3GPP TS 24.007 gives the general description of layer 3 including procedures, messages format and error handling. 1.3 Structure of layer 3 procedures A building block method is used to describe the layer 3 procedures. The basic building blocks are "elementary procedures" provided by the protocol control entities of the three sublayers, i.e. radio resource management, mobility management and connection management sublayer. Complete layer 3 transactions consist of specific sequences of elementary procedures. The term "structured procedure" is used for these sequences. 1.4 Test procedures Test procedures of the GSM radio interface signalling are described in 3GPP TS 51.010 and 3GPP TS 51.02x series.

唉，CSDN的编辑器太不好用了，什么时候能改善下。。。
