3G SGSN sends wireless network access bearer assignment request message (RAB assignment request, Radio Access BearerAssignment Request) to 3G radio network controller (RNC, Radio Network Controller);
3G RNC judges whether the load of current 3G cell-radio network is lower than default thresholding, is then to carry out the common business of 3G network to set up flow process, this business still is carried on 3G network, as shown in Figure 2; Otherwise 3G RNC adjudicates current service bearer at the 2G network, respond RAB to 3G SGSN and assign response (RAB Assignment Response) message, and notice 3G SGSN will call out directed retry (Directed Retry) specifically to the 2G network in this message;
3G RNC sends re-positioning request (Relocation Required) message to 3G SGSN, and informs the target 2G cell of 3G SGSN directed retry in this message; 3G SGSN carries out alternately with 2G SGSN after receiving this message, and the base station controller (BSC by 2G SGSN and target 2G cell, Base Station Controller) finishes after the sub-district switches, return reorientation order (Relocation Command) message to 3G RNC;
