Abstract
The invention discloses a home base station system and a communication method of the home base station system. After receiving ratio-frequency signals sent by a user terminal, multiple front-end modules convert the ratio-frequency signals into uplink data which are sent to a first cloud selector. The first cloud selector sends the uplink data processed by the first cloud selector to a second cloud selector. After processing the uplink data sent by the first selector, the second cloud selector sends the processed uplink data to a gateway. Due to the fact that the processing process of a physical layer and an upper layer in the home base station system exists independently, the first cloud selector or the second cloud selector can dynamically allocate the work of the physical layer entity or the upper layer entity, so that data from any user terminal can be processed at any time, and the specific processed entity can be dynamically various; the home base station system also can achieve different services that different upper entities process the same user terminal at the same time, and fully achieve the resource load balance of the system.
Description
Technical field
