Method one：Macro base station selects to be disturbed maximum micro-base station by strong jamming terminal in micro-base station, by strong jamming terminal Uplink communication be switched to the Microcell for being disturbed maximum micro-base station to be serviced by strong jamming terminal, will be done by strong jamming terminal The Microcell that is serviced of micro-base station for disturbing maximum is used as the uplink service cell of strong jamming terminal.

For this method, when macro base station selects to be disturbed maximum micro-base station by strong jamming terminal in micro-base station, if by force Interfered with terminal is the strong jamming terminal of a relative micro-base station, then macro base station determines that a micro-base station is by strong jamming terminal Disturb maximum micro-base station；If strong jamming terminal is the strong jamming terminal of relatively multiple micro-base stations, macro base station determines each Micro-base station is selected to be disturbed maximum micro- base by strong jamming terminal by the interference size of strong jamming terminal from multiple micro-base stations Stand.

Specifically, can be according to every when macro base station selects to be disturbed maximum micro-base station by strong jamming terminal in micro-base station The interference level of the strong jamming terminal of individual micro-base station measurement is selected, for example, calculated from each micro-base station according to SRS measurement results The micro-base station for selecting interference level maximum in the interference level of obtained strong jamming terminal is finally determined as macro base station will be capable and experienced The micro-base station that terminal is switched to is disturbed, the interference level of the strong jamming terminal of micro-base station measurement can carry micro- in step 502 In the notice for switching over the strong jamming terminal of determination that base station is sent, so that macro base station is received after the notice, can basis The interference level of the strong jamming terminal carried in the notice, so as to select to be disturbed the micro- of maximum by strong jamming terminal in micro-base station Base station.In addition, there is the method that other select to be disturbed maximum micro-base station by strong jamming terminal in micro-base station, for example, Macro base station can send the RSRP of triggering measurement micro-base station message to strong jamming terminal, by each micro-base station of the strong jamming terminal-pair RSRP measure, and return to macro base station by obtained RSRP is measured, macro base station is measured according to the strong jamming terminal The RSRP and the transmission power of the strong jamming terminal arrived, determines interference size of the micro-base station by strong jamming terminal, so that micro- Select to be disturbed maximum micro-base station by strong jamming terminal in base station.Specifically by the way of which kind of selection micro-base station, the present invention is real Example is applied to be not specifically limited this.

For example, in Fig. 4, if strong jamming terminal 1 is only the strong jamming terminal of micro-base station 1, macro base station is determined Micro-base station 1 is maximum by the interference of strong jamming terminal 1, by the uplink communication of strong jamming terminal 1 be switched to that micro-base station 1 serviced it is micro- Cell 1, the Microcell 1 that micro-base station 1 is serviced is used as the uplink service cell of strong jamming terminal 1.If strong jamming terminal 1 It is both the strong jamming terminal of micro-base station 1, while being the strong jamming terminal of micro-base station 2 again, macro base station can be obtained from step 502 The notice that sends of micro-base station 1 in carry in the notice that sends of the interference level of strong jamming terminal 1 that carries and micro-base station 2 it is strong The interference level of interfered with terminal 1, if the interference level of the strong jamming terminal 1 carried in the notice that micro-base station 2 is sent is more than micro- The interference level of strong jamming terminal 1 carried in the notice that base station 1 is sent, then macro base station is by the uplink communication of strong jamming terminal 1 Be switched to the Microcell 2 that micro-base station 2 is serviced, by this by strong jamming terminal 1 disturb maximum micro-base station 2 serviced it is small Area 2 as the upstream service of strong jamming terminal 1 cell.

Alternatively, macro base station in micro-base station except selecting to be disturbed maximum micro- base by strong jamming terminal in the manner described above Outside standing, the strong jamming terminal selection micro-base station that can also have other method to determine, so that the up of strong jamming terminal be led to Letter is switched to the Microcell that the micro-base station is serviced, for example, macro base station can also it is determined that the corresponding micro- base of strong jamming terminal A micro-base station is randomly choosed in standing, thus by the uplink communication of the strong jamming terminal be switched to that the micro-base station serviced it is small Area.Which kind of come to select micro-base station for strong jamming terminal from method for specifically, so that the uplink communication of strong jamming terminal be cut The Microcell that the micro-base station of the selection is serviced is changed to, the embodiment of the present invention is not specifically limited to this.

Method two：Macro base station sends measurement message and gives strong jamming terminal so that strong jamming terminal measures the RSRP of micro-base station, And the maximum micro-base stations of RSRP are selected in micro-base station, the cell ID of micro-base station maximum RSRP is sent to macro base station；It is grand Base station receives the cell ID of the micro-base station for the RSRP maximums that strong jamming terminal is sent, according to the cell of micro-base station maximum RSRP Identify and the uplink communication of strong jamming terminal is switched to the Microcell that the maximum micro-base stations of RSRP are serviced, the RSRP is maximum The Microcell that is serviced of micro-base station as strong jamming terminal uplink service cell.

In general, in method one by strong jamming terminal disturbed the micro-base station of maximum be also in method two RSRP it is maximum Micro-base station.

For this method, strong jamming terminal measures the RSRP of micro-base station, and maximum selection RSRP micro- base in micro-base station When standing, if strong jamming terminal is the strong jamming terminal of a relative micro-base station, strong jamming terminal measures a micro-base station RSRP, and select a micro-base station to be micro-base station maximum RSRP；If strong jamming terminal is relatively multiple micro-base stations During strong jamming terminal, then strong jamming terminal measures the RSRP of multiple micro-base stations, and the selection RSRP maximums in multiple micro-base stations Micro-base station.

For example, in Fig. 4, if strong jamming terminal 1 is only the strong jamming terminal of micro-base station 1, macro base station, which is sent, to be surveyed Message is measured to strong jamming terminal 1 so that strong jamming terminal 1 measures the RSRP of micro-base station 1, it is maximum to determine the RSRP of micro-base station 1, The cell ID of the micro-base station 1 maximum RSRP is sent to macro base station；Macro base station receives the RSRP of the transmission of strong jamming terminal 1 After the cell ID of maximum micro-base station 1, the uplink communication of strong jamming terminal 1 is switched to the Microcell that micro-base station 1 is serviced 1, the Microcell 1 that the maximum micro-base stations 1 of the RSRP are serviced is used as the uplink service cell of strong jamming terminal 1.If strong Interfered with terminal 1 is both the strong jamming terminal of micro-base station 1, while being the strong jamming terminal of micro-base station 2 again, macro base station sends measurement and disappeared Cease to strong jamming terminal 1 so that strong jamming terminal 1 measures the RSRP of micro-base station 1 and micro-base station 2 respectively, if strong jamming terminal 1 The RSRP of the micro-base station 2 measured is more than the RSRP of micro-base station 1, then strong jamming terminal 1 is by the cell of micro-base station 2 maximum RSRP Mark is sent to macro base station；Macro base station is received after the cell ID of the micro-base station 2 of the RSRP maximums of the transmission of strong jamming terminal 1, Uplink communication is switched to the Microcell 2 that micro-base station 2 is serviced, the Microcell 2 that the maximum micro-base stations 2 of the RSRP are serviced It is used as the uplink service cell of strong jamming terminal 1.
