scope:

The present document gives an overview of the tasks undertaken by a GMR-1 Mobile Earth Station (MES) when in idle mode, that is, switched on but not having a dedicated channel allocated, e.g. not making or receiving a call. It also describes relevant network functions. The idle mode functions are also performed by a MES as long as no dedicated channel is allocated to the MES.

The present document outlines how the idle mode operation shall be implemented. Further details are given in GMR-1 3G 44.008 [4] and GMR-1 3G 45.008 [7]. Clause 4 of the present document gives a general description of the idle mode process.

Clause 5 outlines the main requirements and technical solutions of those requirements. Clause 6 describes the processes used in idle mode.
