Hi, I would like to know how the roaming operator selection works in cellular based networks, does my (hoome) operator provide me with a list of roaming operators. First of all, how the network recognition works, is it based on a string that is broadcasted by the basestations i.e., how does my mobile recognize that there is a base station of my operator. When away from my operators coverage area, how does it recognize which networks have roaming agreements with my home operator. Is it something thats done more by the base station than by my mobile phone (e.g., it could be that my cell broadcasts saying 'i belong to this operator, anyone there')
Can someone point me to the formal document(s) that specify this
Regards, greenhorn.
