1 Scope
The present document specifies the Radio sub-system link control implemented in the Mobile Station (MS), Base
Station System (BSS) and Mobile Switching Centre (MSC) of the digital cellular telecommunications systems GSM.
Unless otherwise specified, references to GSM also include include operation in any band.
1.1 References
The following documents contain provisions which, through reference in this text, constitute provisions of the present
document.
• References are either specific (identified by date of publication, edition number, version number, etc.) or
non-specific.
• For a specific reference, subsequent revisions do not apply.
