Embodiment 1

[0045] Figure 3A , Figure 3B It is a schematic structural diagram of a wireless device controller according to an embodiment of the present invention.

[0046] The wireless device controller 301 is applied in the wireless communication system 30, and the REC_1 301 is connected to at least one multi-mode wireless device 305, and the REC_1 301 includes:

[0047] Wireless Device Controller - Wireless Device Interface Module 307 for connecting to RE 305; and

[0048] A cascade interface module 309 for connecting at least one other wireless device controller (REC_2 302 and / or REC_3 303);

[0049] Among them, REC_1 301 supports at least one wireless communication standard;

[0050] The wireless device controller-wireless device interface module 307 is connected to the RE305 through a physical link 311; and

[0051] The RE 305 exchanges data with at least one other wireless device controller (REC_2 302 and / or REC_3 303 ) through the wireless device controller-wireless device in...

Embodiment 3

[0062] Figure 5 It is a schematic structural diagram of a wireless device controller according to an embodiment of the present invention.

[0063] On the basis of the second embodiment, this embodiment further includes a data processing module 504, configured to: receive a part of the first data distributed to REC_1 301; and perform data processing, and send the processed data through the data distribution / Aggregation module 404 transmits to RE 305 .

[0064] In various embodiments of the present invention, the benefit of separating the data processing function from the data distribution / aggregation function is to enhance the robustness of the system. Data processing function failure will not affect data distribution / aggregation function. For example, when the data processing module 504 of REC_1 301 fails, as long as the data distribution / aggregation module 404 of REC_1 301 works normally, the normal communication between RE305 and REC_2 302 will not be affected.

Embodiment 4

[0066] Image 6 It is a schematic structural diagram of a wireless device controller according to an embodiment of the present invention.

[0067] This embodiment takes Figure 3B Take the system connection method as an example.

[0068] On the basis of Embodiment 1, this embodiment further includes:

[0069] The first data receiving module 601 is configured to receive the first data from the wireless device 305 transmitted through the wireless device controller-wireless device interface module 307;

[0070] A data distribution module 603, configured to distribute a part of the first data to the wireless device controller 301, and distribute a part of the first data to another wireless device controller 302;

[0071] The second data receiving module 602 is configured to receive second data including data from another wireless device controller 302 transmitted through the cascade interface module 309; and

[0072] The data aggregation module 604 is configured to aggregate t...

Abstract

The embodiment of the invention provides a wireless device controller, which is applied in a wireless communication system, and is connected with at least one multimode wireless device; and the wireless device controller comprises a wireless device controller-wireless device interface module used for connecting the wireless device controller and the wireless device, and a concatenation connection interface module used for connecting at least one wireless device controller and another wireless device controller; and the wireless device controller-wireless device interface module is connected with the multimode wireless device through a physical link. The embodiment of the invention also provides a wireless communication system and a communication data transmission method; and the RE can perform data interaction with various RECs through one physical link in the various embodiments of the invention. The different RECs can share the physical bandwidth of the physical link connected with the RE; the transmission cost is reduced; the REC-RE interface number of the RE can also be greatly reduced, and wiring complexity and the installation cost of the system can be reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless device controller, a wireless communication system and a communication data transmission method. Background technique [0002] The radio base station system may be divided into a radio equipment controller (Radio Equipment Controller, REC for short) and a radio equipment (Radio Equipment, RE for short). The interface connecting the REC and the RE may be referred to as a REC-RE interface. [0003] The Common Public Radio Interface (CPRI for short) standard is an interface standard formulated by communication equipment manufacturers. In this standard, the REC-RE interface connecting the REC and the RE may be called a CPRI interface. [0004] The Open Base Station Architecture Initiative (OBSAI) standard is another interface standard developed by communication equipment manufacturers. In this standard, the REC-RE interface connecting REC and RE may be called OBSAI interface. ...
