5.8 Case Studies
This section deals with some case studies related to practical implementation issues. The first subsection explains which parameters have to be considered when determining the SPLIT_PG_CYCLE value. The second subsection deals with the resource allocation strategy problems. The third subsection addresses the problem of acknowledgment reporting. The last subsection deals with dynamic coding scheme adaptation algorithm.
5.8.1 Determination of SPLIT_PG_CYCLE Value
The goal of this section is to show the impact of the SPLIT_PG_CYCLE value on paging occurrence, on the strategy to perform measurements and BSIC decoding on neighbor cells, and on power saving management for the MS. The parameter SPLIT_PG_CYCLE indicates the paging occurrence of a paging subchannel within a 52-multiframe or 51-multiframe in DRX mode for GPRS services. This parameter is positioned by the MS during the GPRS attach procedure and is not negotiated between the MS and the network.
The SPLIT_PG_CYCLE directly impacts the following actions performed by the MS in packet idle mode:
-
Paging decoding according to DRX parameters;
-
Measurements on the serving cell and on neighbor cells for the cell-reselection algorithm;
-
BSIC decoding on each of the six best neighbor cells.
As will be shown in the next sections, the paging recurrence has an impact on the two last actions listed above. This case study concerns SPLIT_PG_CYCLE only for the 52-multiframe, not the 51-multiframe.
5.8.1.1 Performed Measurements
There is a benefit for the MS in performing all measurements for cell reselection during the paging decoding process in order to stop its radio...
