03.133GPPDiscontinuous Reception (DRX) in the GSM systemTS

There will be occasions when it is necessary to alter the parameters of cell such that the paging group of the MS may alter.

If (referring to Technical Specification GSM 05.02) any of the parameters BS_AG_BLKS_RES, BS_CC_CHANS_COMB, BS_CC_CHANS or BS_PA_MFRMS have to be altered, then the period when page requests may be lost can be minimised for example by:

Firstly setting the page mode to "page reorganisation" in all page requests on the affected cell for the exact duration of one paging period (i.e. BS_PA_MFRMS multiframes). At the completion of this announcement period, the BCCH parameters are set to the new values and the BSS starts scheduling the paging messages according to the new parameters. The page mode is reset to any of the values "normal mode" or "extended mode" as required.
