Abstract
A method for establishing a logical connection between a plurality of sites (101-110) and either a plurality of site controllers (112-115) or a switching center (117) in a radio communication system (100) may be accomplished in the following manner. A first site (101) is selected from a first pair of sites (101,104), wherein the geographical separation (119) between the first pair of sites (101, 104) exceeds the geographical separation between any other pair of sites. Upon selecting the first site (101 ), at least a second site (106, 108) is selected to form a group of selected sites (101,106-108). The group of selected sites (101,106-108) is assigned to a first site controller (112), or a first control portion (201) of the switching center (117), such that communication resources provided by the group of selected sites (101,106-108) can be accommodated by the assigned controller (112), or control portion (201). Similar to the selection of the first site (101 ), a third site (102) is selected from a second pair of sites (102, 104) and is assigned to a second site controller (114), or a second control portion (202) of the switching center (117), to establish the respective logical connection.
