8.18 AT^SPCL Set Preferred Cell List
AT^SPCL can be used to specify a list of cells the ME shall preferably register to. The list may contain up to 8
pairs of location area code and cell ID. The list is stored non-volatile.
If a preferred cell list is available the ME will try to register to one of the listed cells, regardless of signal strength
and quality. If more than one of the listed cells is visible on the air interface, the one with the best signal strength
and quality is chosen to register to. If none of the listed cells is currently visible on the air interface, the normal
cell selection mechanism applies.
Preferred cell registration works only in the home PLMN.
If the list is written with less than 8 elements then all other elements remain unchanged.
Syntax
Unsolicited Result Code
The following URC is available as long as the preferred cell registration feature is enabled, i.e., as long as a pre-
ferred cell list is configured. After erasing the list with AT^SPCL=0 the URC is no longer generated.
^SPCL: <status>
The URC indicates whether the ME has registered to one of the listed cells or has lost registration to a listed cell.
