Embodiment Construction

[0042] In order to realize baseband resource sharing, such as figure 1 The realization of the shared rack networking scheme shown is realized, figure 1 Schematic representation in the form of a rack, such as figure 1 As shown, a rack may include multiple BBUs and a switching unit, and each BBU communicates with the switching unit and is connected through the switching unit to form a large-capacity rack. The capacity of the rack is equal to the The sum of the capacities of all BBUs, each BBU includes several baseband processing units.

[0043] The baseband resource sharing of all BBUs in the rack is realized through the switching unit, so that the baseband resource multiplexing capability of the entire rack is no longer limited to a single BBU. When a cell is established, it is necessary to allocate baseband resources for the carrier frequencies under the cell, and the increase in the baseband resources supported by the baseband pool means that the carrier frequency capabilit...

Abstract

The invention provides a business processing method and system based on base band resource sharing. The method comprises the step of distributing base band processing unit resources for cell carrier frequency according to the shortest principle of a resource link when a base band unit (BBU) receives the cell establishing requirements of a local cell sent by a wireless network controller (RNC). After the BBU receives the cell establishing requirements sent by the RNC, the base band processing unit resources are distributed for the cell carrier frequency in shared base band resources according to the shortest principle of the resource link, the utilization rate of the base band resources is improved on the premise that the cost does not need to be added massively, the BBU shared by every base band resource can communicate with the RNC simultaneously, a business burden is shared, and performance is improved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a service processing method and system based on baseband resource sharing. Background technique [0002] The connection between the base station and the radio network controller (Radio Network Controller, RNC) in the wireless network may adopt an IP method or an asynchronous transfer mode (Asynchronous Transfer Mode, ATM). The base station mostly adopts the architecture of BBU+RRU. This architecture divides the base station into two parts: the building baseband unit (Building Baseband Unit, BBU) and the radio remote unit (Radio Remote Unit, RRU). The connection between the base station and the RNC is realized through the BBU. . [0003] When the base station receives the cell establishment carrier frequency message from the RNC, the base station needs to allocate baseband resources for the carrier frequency. The number of baseband resources of a single station is lim...
