Problems solved by technology

[0005] The current baseband pool only implements baseband resource sharing within a BBU. The capacity of a single BBU is limited, and the hardware cost of the BBU and the existing hardware integration level limit the number of baseband resources that can be reused.

Abstract

The invention discloses a base band resource sharing method of a high-capacity base band pool. The base band resource sharing method of the high-capacity base band pool comprises: when a battery backup unit (BBU) can not acquire needed base band resources from the BBU, the BBU requests unoccupied base band resources from other network elements, and the other network elements search for the unoccupied base band resources from the other network elements and other BBUs connected with the other network elements. The invention further provides a base band resource sharing system of the high-capacity base band pool. Through the base band resource sharing method and the system of the high-capacity base band pool, dynamic sharing of the base band resources between the BBUs in the high-capacity base band pool can be achieved, and therefore base band resource reuse capacity of the whole high-capacity base band pool is not limited by a single BBU.

Description

technical field [0001] The present invention relates to the field of wireless networks, in particular to a method and system for sharing baseband resources of a large-capacity baseband pool. Background technique [0002] In the current wireless network, the base station mostly adopts the architecture of baseband processing unit (BBU, Building Base band Unit) + radio frequency remote unit (RRU, Radio Remote Unit). The two are connected by optical fiber, and BBU and RRU can be a pair One-to-many or one-to-many. This BBU+RRU architecture allows baseband resources to be placed in a centralized manner, enabling the sharing of supporting resources such as computer rooms, backup power, and transmission, reducing network construction costs, reducing network energy consumption, facilitating network maintenance, and reducing operation and maintenance costs. [0003] Generally speaking, the baseband resources in the BBU are dynamically shared with the RRU. That is to say, a certain ca...
