AT command - 3G connection to another cell -

-

i'm using sierra wireless modems (compass 880/888, usb 308) , i'm trying find @ command tell modem connect cell (to tower). reason want because when i'm in crowded place, cellular network down, want use next nearest cell. possible?

i doubt there command this; handoff between cells controlled & initiated network.
despite fact decision made based on data comes from phone @ protocol level (relative signal strengths of surrounding 16 cells) can't force far i'm aware - there never point in doing so:

if cellular device drops off it's network everyting in power rectify situation - if there cell station in range belonging home network (or 1 can roam on) try attach automatically, if not keep on looking.

if dropped due capacity problems the base station controller (the govenor of bunch of cell sites) should have tried spread load adjacent cells knows attached devices in range of, if thats fails bet saturated too, switching them of no use.
