| 24.008 | Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 |
Must Have |
| �@是我最常用到的spec之一，�ξ叶�言也是最入�T的一份。大多��spec是用�聿榈模�但是�@份�牡谒恼麻_始是可以一� ��x�^的。它定�x了Mobility Management(MM/GMM)、Call Control(CC)、Session Management(SM)的程序�有OTA Message封包�热�(照spec本身的用字：定�xradio interface procedures)。另外，要找MM/SM的Timer，要找error cause (CC/GPRS SM)也都是�@份。 | ||
| 25.331 | Radio Resource Control (RRC); Protocol specification |
Must Have |
| 份量很�@人的一份常用spec。比�^�y逐��x起，因�橛泻芏喑绦蛐缘�|西。通常是用想的，把程序背後的��想懂，不然就 是多查�状尉���起�怼Ｄ��很有名的RRC States and State Transitions就定�x在�@份�e面。另外，所有的System Information Block、RRC程序、Handover程序、RAB程序、PAGING TYPE 1和PAGING TYPE 2的格式�c定�x，�有那堆��a��b��c��d..的measurements全都在�@�。�x完24.008和25.331算是可以解�Q掉7成以上的OTA message，剩下的，它�����兔�refer��refer去。RRC protocol Timer�查�@份。 | ||
| 23.060 | General Packet Radio Service (GPRS); Service description;Stage 2 | Must Have |
| PS domain的重量�spec。那��有名的GPRS Core Network的架���D、一堆u-plane、c-plane的堆�B架���D、UE Operation Mode分成class A, class B, class C(此分��m用於所�^俗的2G… 即A/Gb mode… ��22.060)或PS/CS mode(此分��H�m用通俗所�^3G… 即Iu mode)、Packet Data Protocol States、���domain的Paging Co-ordination通通都在�@�。PDP Context Preservation在第9章。 | ||

| 24.007 | Mobile radio interface signalling layer 3; General aspects |
Must Have |
| �@份比�^�凫杜fGSM���，比�^少用到，通常是碰到TI solution才��查到它。它��被我列成must have是因�樗�有一��很�典的Protocol architecture of Non Access Stratum (CS/PS MS side)的架���D，可以�我��一眼看清RR, (G)MM, CM(CC/SM/SS/SMS)的�P�S。 | ||
| 25.301 | Radio Interface Protocol Architecture | Must Have |
| ��邓愫苌伲�但是算非常架��性的一份大spec，要知道L1、L2、L3倒底差在哪，�有各�娱g的channel到底怎 ��mapping，都在�@份。�@���也是比�^算用�聿榈�spec，�σ��新手而言，光是看到一大堆channel�s不了解它��究竟是做什�N的�r候，�@份 spec���很�y看得�M去。另外，R6起就同�r收有分�e��HSDPA/HSUPA的HS-DSCH/E-DCH definition，�@份就不重�}列在下面的HS spec��^了。 | ||
