Embodiment 1

[0037] This embodiment describes the structure of the distributed base station controller, and the structure of the central unit and the remote unit.

[0038] In the current mobile communication system, such as WCDMA / CDMA system, the components of the base station controller usually consist of the following necessary logical parts:

[0039] The interface unit is used to provide uplink and downlink physical interfaces, the uplink interface interacts with the core network nodes, and the downlink interface interacts with the base station;

[0040] a signaling processing unit, configured to provide signaling processing capabilities;

[0041]A business processing unit, configured to provide business processing capabilities;

[0042] The operation and maintenance unit is used to provide system management functions, such as configuration, alarm, maintenance, performance statistics, etc.;

[0043] The clock unit is used to provide a clock for the system.

[0044] The clock unit and...

Embodiment 2

[0080] This embodiment describes the networking structure of the wireless access network based on the distributed base station controller, and the processing flow of the distributed base station controller.

[0081] see Figure 8A , is one of the schematic diagrams of the access network based on the distributed base station controller according to the second embodiment of the present invention. In the access network, a central unit C_BSC is included, and the C_BSC can be directly connected to the BTS, or can be connected to one or more The remote unit R_BSC, one R_BSC can gather several base stations and implement call processing of these base stations. in,

[0082] C_BSC mainly provides the sharing function of the base station controller. One or more C_BSCs may be included in the access network. Some remote sub-units can also be selected inside the C_BSC as needed. Generally, C_BSC can be deployed in central cities according to the principle of easy maintenance, for examp...

Embodiment 3

[0103] This embodiment describes the wireless access network structure and the data processing process in which the SDU unit with the soft handover combining function in the distributed base station controller is transferred to the transmission convergence node.

[0104] see Figure 9A , is one of the schematic diagrams of the access network using the remote unit (SDU unit with soft handover combining function) in the distributed base station controller as the transmission aggregation node according to the third embodiment of the present invention. In the access network, it includes multiple BTSs, some of which are converged to R_BSC1 (its structure can be as follows Figure 4A or Figure 4C As shown), a part of BST converges to R_BSC2 (its structure can be as follows Figure 4A or Figure 4C shown), R_BSC1 and R_BSC2 are connected to C_BSC through a transmission network (such as a synchronous digital transmission network SDN transmission network) (its structure can be as f...

Abstract

The invention discloses a distributed base station controller and a unit thereof and a data transmission method, wherein, the distributed base station controller includes a central unit and at least one pulling unit. The central unit is used to convert protocols of interactive signaling and business data between core network node and the pulling unit and perform operation processing in weak correlation with business for the pulling unit. The pulling unit is used to convert protocols of signaling and business data between the central unit and the base station, perform multi-drop merging and converging processing for received up data and sent to the central unit. When the pulling units are more than one, connect with the central unit respectively or in cascade connection with the central unit. The invention can realize flexible networking mode, deploy a SDU unit with multi-drop merging function in the distributed base station controller on a transmission converging node of wireless access network and improve the converging capability of the transmission converging node.

Description

technical field [0001] The present invention relates to the communication field, in particular to a distributed base station controller, a central unit, a remote unit, and a data transmission method in the distributed base station controller. Background technique [0002] At present, most metropolitan land mobile transmission networks are divided into three-layer network structures: core layer, aggregation layer and access layer. The core layer is deployed in the central office, which is connected to the nodes of the convergence layer through the optical fiber network; the nodes of the aggregation layer are deployed in the central computer room or module office of the community; the access layer provides access ports for users. [0003] The core layer uses high-speed optical links to interconnect, mainly to provide fast forwarding of network data packets and interconnection between aggregation nodes. [0004] The convergence layer is mainly composed of transmission equipmen...
