Embodiment Construction

[0106] The basic idea of ​​the present invention is to separate the baseband part and the radio frequency part of the base station to form a baseband unit (BBU, baseband Unit) and a radio frequency unit (RFU, Radio Frequency Unit), and the RFU is provided with a device for interconnecting with the BBU and transmitting data information. The baseband radio frequency interface, thus forming a split base station system. Moreover, on the basis of the separation of BBU and RFU, the BBU capacity is further divided, and each unit is also placed separately, so that each baseband unit can support the minimum configuration, and multiple baseband units can be combined to support the macro base station. capacity. In the present invention, the transmission unit, main control and clock synchronization unit, baseband signal processing unit and interface unit of the BBU are highly integrated and designed, such as integrated on a single board, and set in a small BBU box. Form a field replaceab...

Abstract

The present invention provides a split type base station system and its network organizing method and baseband unit, the system separates the baseband unit of the base station with a RF unit, and the RF unit is provided with a baseband RF interface mutually connected with the baseband unit and transmitting data information, so as to form the split type base station system. On the basis of the separation of the BBU and the RFU, the BBU capacity is further divided, each unit is separately allocated; by a dilatancy interface and a baseband RF interface provided by a BBU interface unit, the network organizing of the BBU is flexibly and conveniently realized, the dilatancy reduces the occupation area, reducing operation cost, improving the credibility of the work of the base station system.

Description

technical field [0001] The invention relates to base station technology, in particular to a split base station system, its networking method and base band units forming distributed base stations. Background technique [0002] In the mobile communication system, the base station is an important part of the mobile communication network. It is connected between the user terminal and the base station controller, and is used to send and receive wireless signals, so that the user terminal can access the wireless network, and at the same time complete the communication with the base station controller. information interaction. figure 1 It is a schematic diagram of the composition structure of the base station in the mobile communication system, from figure 1 It can be seen that the base station mainly includes: [0003] The interface between the base station and the base station controller is used to complete the interface function between the base station and the base station co...
