A load balancing method and system is provided. When a terminal enters an idle, access or service state, and a base station determines that the terminal is in a multi-band covering section, load conditions of the bands in the section are recorded; and when determining that a preset idle or access or service state condition is met based on the recorded load conditions of the bands in the section, the base station performs load balancing control on the terminal. For the terminal in the idle, access or service state, load balancing for a multi-band network can be implemented. |

1. A load balancing method for a multi-band network, comprising:
when a terminal enters an idle, access or service state, and a base station determines that the terminal is in a multi-band covering section, recording load conditions of the bands in the section, wherein the recorded load conditions of the bands in the section comprises load conditions of source bands and target bands on which load balancing control is performed; and when determining that a preset idle or access or service state condition is met based on the recorded load conditions of the bands in the section, performing, by the base station, load balancing control on the terminal; wherein in the case that the terminal enters the idle state, when determining that the preset idle state condition is met based on the recorded load conditions of the bands in the section, performing, by the base station, load balancing control on the terminal, comprises: when determining that the source band is not as same as the target band, the instant load of the source band is larger than a preset load threshold of the source band, and the instant load of the target band is smaller than a preset load threshold of the target band, performing load balancing control on the terminal; wherein in the case that the terminal enters the access state, when determining that the preset access state condition is met based on the recorded load conditions of the bands in the section, performing, by the base station, load balancing control on the terminal, comprises: when the terminal has an air interface version number larger than or equal to 8, the terminal transmits an incall message with a ALT_BAND_CLASS_SUP equal to 1 to the base station, the source band is not as same as the target band, and both the source band and the target band are deployed in the section, determining whether the preset access condition is met; otherwise, performing a first type of load balancing control; and wherein the determining whether the preset access condition is met comprises: when the instant load of the source band is larger than the preset load threshold of the source band, the instant load of the target band is smaller than the preset load threshold of the target band, determining that the preset access state condition is met, and performing a second type of load balancing control; otherwise, determining that the preset access state condition is not met, and performing a first type of load balancing control; wherein in the case that the terminal enters the service state, when determining that the preset service state condition is met based on the recorded load conditions of the bands in the section, performing, by the base station, load balancing control on the terminal, comprises: when the instant load of the source band is larger than the preset load threshold of the source band, and a specific band set is not empty, performing load balancing control on the terminal. |
