Step S210: communication system network, according to the adjustable strategies determined, carries out air interface adjustment to the mobile terminal of weak overlay area, terminates this air interface adjustment flow process.
The policy library of step S212: communication system network inquiry RLS algorithm default configuration, determines that the mobile terminal to non-weak overlay area carries out the adjustable strategies of the system default of air interface adjustment.
The air interface adjustable strategies of system default configuration is preserved in the policy library of RLS algorithm default configuration, air interface adjustable strategies as original in TD-SCDMA system, the original adjustable strategies of these systems can be the strategy of the interior adjustment of intersystem handover and/or system.Wherein, when mobile terminal is in non-weak overlay area, in system, adjustment comprises cell merge, carrier frequency adjustment, time slot adjustment, speed adjustment etc.
Step S214: communication system network, according to the adjustable strategies determined, carries out air interface adjustment to the mobile terminal of non-weak overlay area, terminates this air interface adjustment flow process.
By the present embodiment, when communication system network detects the link quality degradation of mobile terminal, first judge whether mobile terminal is in weak overlay area, next mobile terminal being in weak overlay area can customize distinctive air interface adjustable strategies.Whether the TD radio link quality monitoring algorithm that the present embodiment proposes is in the thinking of weak overlay area in conjunction with user, simultaneously for the user of weak overlay area, when network monitor is to when being in weak overlay area, and can custom tailored strategy to this scene.Can in conjunction with the coverage condition of community and adjacent area in such practical application, the adjustable strategies of flexible configuration RLS algorithm, automatically realize the judgement of weak overlay area by program and perform corresponding adjustment, thus give full play to the effect of RLS algorithm, and reduce the call drop caused because of blindly adjusting in weak overlay area.
