Lifting a specific embodiment is elaborated
Suppose that UE0 current service cell is community A, the small-cell base station that community A has been activated is administered, demand due to network capacity, or the current mobile communication of UE0 is second-rate, UE0 need to find adjacent area, but adjacent area is to be administered by the small-cell base station of dormancy, these small-cell base stations only send discovery signals or synchronizing signal etc. with the longer cycle, and this can cause UE0 to find that the efficiency of adjacent area is higher.
Because these adjacent areas are by the discovery signals of self, the configuration of synchronizing signal or measuring reference signals, sequence signature for example, time slot position and cycle etc. have sent to logic control element, and logic control element has also determined that by reporting of community A adjacent area is small-cell base station B, small-cell base station C and adjacent area, small-cell base station D place, so self configuration information of adjacent area is sent to community A by first interface, by community, A is transmitted to UE, make UE in corresponding time-frequency position, to carry out the discovery of adjacent area according to self configuration information of adjacent area, and by community A, report logic control element after measuring according to the configuration of measuring reference signals.
Logic control signal is according to self configuration information of the measurement result that reports and adjacent area, according to the algorithm setting in advance or strategy, determine which concrete adjacent area should activate and carry out the access of UE0, for example now determine that small-cell base station C should activate, so logic control signal sends the first control information to small-cell base station C, comprise the control information of the small-cell base station C that triggers the activation, power control information, the carrier frequency information adopting, if tdd systems, also comprise the uplink and downlink timeslot configuration information of employing etc., when small-cell base station C receives this first control information, activate.Small-cell C after activation just can make UE normally be switched in the C of small-cell, and service is provided.
