Problems solved by technology

[0005] The defect of the existing technology is: during the RRU start-up and normal operation, the RRU-related parameters on the BBU may change. At this time, the RRU cannot respond to the parameter changes on the BBU in a timely manner, which may cause the two to be out of sync. The parameters of the RRU are modified

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] The parameter synchronization method of the present invention is that after the RRU is started, it actively requests the BBU for parameter synchronization, and does not enter the normal working state until the parameters are obtained from the BBU; and when the parameters related to the RRU on the BBU change, the BBU immediately updates the latest parameter Send it to the RRU to ensure that the RRU can update the parameters synchronously with the BBU.

[0033] Referring to Fig. 1 and 2, the process of synchronizing with the BBU parameter after the RRU in the specific embodiment of the present invention starts, mainly comprises the following steps:

[0034] (1) The RRU sends a request parameter configuration message to the BBU. In the case of multiple RRUs, the RRU identity mark RRUID may be included in the message so that the BBU can identify it. The method of ...

Abstract

The invention discloses a synchronization method of remote end radio frequency unit parameters that includes following processes: A. the remote end radio frequency unit is started to send parameter distribution requirement to base band control unit; B. the base band control unit sends the related parameter of the remote end radio frequency unit to the remote end radio frequency unit; C. the remote end radio frequency unit distributes the parameters based on received parameters to start normal work. The method of the invention obtains parameters from BBU when RRU is started to guarantee the RRU and relate parameters of RRU are in-phase, so the parameter synchronization is in time and reliable.

Description

technical field [0001] The invention relates to a parameter synchronization method of a remote radio frequency unit and a baseband control unit in a wireless communication system. Background technique [0002] The architecture development of the wireless communication system has gradually formed such a trend: the radio frequency unit is separated from the baseband control unit (BBU), and the two are connected by long-distance transmission means (optical fiber or cable), and then the radio frequency unit is placed in various required The place is called the remote radio unit (RRU). The advantage of this architecture is that the two independent parts are separated and developed independently, which not only reduces the cost, but also improves the flexibility of networking and facilitates engineering installation. Therefore, this architecture is more and more recognized by users, and there are more and more application occasions. [0003] Under the architecture of BBU+RRU, us...
