Description
Technical Field
The present invention relates to the field of communications, and in particular, to a wireless device controller, a wireless communication system, and a communication data transmission method.
Background
The Radio base station system may be divided into a Radio Equipment Controller (REC) and a Radio Equipment Controller (RE). The interface connecting the REC and the RE may be referred to as the REC-RE interface.
The Common Public Radio Interface (CPRI) standard is an Interface standard established by communication equipment manufacturers. In this standard, the REC-RE interface connecting REC and RE may be referred to as a CPRI interface.
The Open Base Station Architecture Initiative (OBSAI) standard is another interface standard established by communication equipment manufacturers. In this standard, the REC-RE interface connecting REC and RE may be referred to as an OBSAI interface.
With the rapid development of wireless network technology, the industry has proposed the concept of multi-mode base station in order to protect the investment of operators and reduce the risk caused by market change. One expression of the multimode base station concept is: the base station simultaneously supports two or more than two communication modes in one cabinet.
The advantages of the multimode base station are mainly:
(1) the base station equipment can be reused, and the method comprises the steps of reusing a hardware platform and a software architecture;
(2) repeated installation of equipment can be reduced, and the space of the station site is reduced.
For example, the GSM/UMTS dual mode base station concept emerged in the late nineties of the twentieth century with the growing maturity of IMT-2000(International Mobile Telecommunication-2000) technology. However, as the life cycle of GSM is much longer than expected, Software Defined Radio (SDR) technology has a slow breakthrough, and multimode base stations based on SDR technology are far from meeting the needs of operators.
The market demand for multi-mode base station solutions is still very urgent.

Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail. Moreover, various functional blocks are presented in some figures. Those skilled in the art will appreciate that the functions may be implemented using individual hardware circuits, using software functioning in conjunction with a suitably programmed digital microprocessor or general purpose computer, using an Application Specific Integrated Circuit (ASIC), and/or using one or more Digital Signal Processors (DSPs).
The embodiment of the invention is mainly explained by taking the situation in a WCDMA/GSM dual mode (W/G dual mode) as an example, and dual modes or multi-mode combinations of other modes, such as: GSM, CDMA, WCDMA, TD-SCDMA, LTE (Long Term Evolution), WIMAX, Ultra Mobile Broadband (UMB), Personal Handyphone System (PHS), Air Interface Evolution (Air Interface Evolution, AIE), and any combination of two or more of the new wireless communication systems that follow the Evolution may be analogized, for example: WCDMA/CDMA dual mode, WCDMA/WIMAX dual mode, WCDMA/GSM/CDMA multi mode, etc. The embodiment of the present invention mainly takes a CPRI interface as an example, and the types of interfaces between other REC-REs, for example: the OBSAI interface, the Ir interface involved in TD-SCDMA, and other REC-RE proprietary protocol interfaces that the equipment vendor defines themselves may be analogized. Similarly, some entities/devices/apparatuses/units with specific names related to the embodiments of the present invention may be replaced with entities/devices/apparatuses/units with the same or similar functions, which are not described in detail.
Fig. 1 is a schematic diagram of a radio base station system _100 including REC and RE.
REC _101 generally includes: a transmission module _103 connected to the network controller _110, a BB (BaseBand) module _105 connected to the transmission module, a BaseBand rf interface module _107 connected to the BaseBand module, and a master clock module _109 connected to the transmission module, the BaseBand module, and the BaseBand rf interface module. In implementation, the functional modules may be highly integrated, for example, integrated on one or more boards, and disposed in a Baseband Unit (BBU) box with a small volume, so as to form a Field Replaceable Unit (FRU).
On the uplink, under the control of the master clock module, the signal from the RE is transmitted to the BB module through the baseband rf interface module for processing, for example: and demodulating and decoding, and finally transmitting the information to a network controller through a transmission module.
On the downlink, under the control of the master clock module, the signal from the network controller is transmitted to the BB module through the transmission module for processing, for example: and coding and modulating, and then transmitting the processed signal to the RE through a baseband radio frequency interface module.
RE _111 generally comprises: an REC-RE interface module _113 connected with the REC, a master clock module _119 connected with the REC-RE interface module and a middle radio frequency module (RF/IF module) _ 117. In the RF/IF module, IF is an optional module, i.e., the RF/IF module may include only an RF module.
On the uplink, signals from the air interface are processed by the RF/IF module, for example: radio frequency filtering amplification, down conversion, analog-to-digital conversion, digital filtering and the like, and then transmitting the processed signals to the REC through the REC-RE interface module.
On the downlink, signals from the REC are transmitted to the RF/IF module through the REC-RE interface module for processing, for example: digital-to-analog conversion, up-conversion filtering amplification and the like, and finally transmitting the signals through an antenna.
The morphology of the RE may include: a Radio Remote Unit (RRU for short), a Radio and Filter Unit (RFU for short), a Radio Unit supporting multiple communication systems, and so on.
The REC-RE interface may be an optical interface or an electrical interface. Typically, optical interfaces are used for long distance connections and electrical interfaces are used for short distance connections.
For example, in a UMTS system, the REC basically involves Iub transport and Iub protocols, Node B control and management, and digital baseband processing, in summary. For the downlink (from REC to RE), the REC handles such operations as channel coding, interleaving, spreading, scrambling, addition of physical channels, controlling the transmit power of each physical channel, frame and slot signal generation (including clock stabilization). For the uplink (from the RE to the REC), the REC processes operations such as channel decoding, deinterleaving, despreading, descrambling, signal distribution to signal processing units, detection of feedback information for transmit power control, and signal-to-interference ratio measurement. The RE provides analog and radio frequency functions such as filtering, modulation, frequency conversion and amplification. For the downlink, the RE performs operations such as digital-to-analog conversion, up-conversion, on/off control of each carrier, carrier multiplexing, power amplification and limitation, antenna monitoring, and RF filtering. For the uplink, the RE performs operations such as analog-to-digital conversion, down-conversion, automatic gain control, carrier demultiplexing, low noise amplification, and RF filtering.
Referring to fig. 2, a schematic diagram of a multimode wireless base station system in the prior art is shown.
In the figure, the RE simultaneously supports two or more wireless communication systems, and the RE is connected with the REC _1 and the RE is connected with the REC _2 through independent optical fibers or cables. The interface for connecting the RE and the REC may be a CPRI interface. The cables or optical cables for transmitting CPRI interface information between different RECs and REs are independent. Because of the advances in technology, bandwidth on a set of fiber or cable can carry multiple CPRI interface information simultaneously. Therefore, the connection mode of a set of optical fibers or cables of the prior art CPRI interface actually causes the waste of the optical fibers or cables. Meanwhile, the connection mode of one CPRI interface and one set of optical fiber or cable objectively requires that the RE needs to have a plurality of REC-RE interfaces, which greatly increases the design and manufacturing cost of the RE. Meanwhile, the REC-RE interfaces are more, so that the complexity of system wiring and the installation cost are increased.
Example one
Fig. 3A and fig. 3B are schematic diagrams of a wireless device controller according to an embodiment of the present invention.
The radio equipment controller 301 is applied to the radio communication system 30, wherein the REC _ 1301 is connected with at least one multimode radio equipment 305, and the REC _ 1301 comprises:
a wireless device controller-wireless device interface module 307 for connecting to the RE 305; and
a cascade interface module 309 for connecting at least one further radio equipment controller (REC _2302 and/or REC _ 3303);
wherein, the REC _ 1301 supports at least one wireless communication system;
wireless device controller-wireless device interface module 307 is connected to RE305 via a physical link 311; and
RE305 interacts data with at least one other radio device controller (REC _2302 and/or REC _ 3303) through radio device controller-radio device interface module 307 and cascade interface module 309.
In this embodiment, the RE interacts data with different RECs (301, 302, 303) via one physical link 311. The different RECs (301, 302, 303) share the physical bandwidth of this physical link to the RE, for example: the bandwidth on the physical link 311 may simultaneously carry multiple CPRI interface information. Compared with the mode that RE is respectively connected with REC, the solution of the implementation reduces the transmission cost, the number of REC-RE interfaces of RE is greatly reduced, and the complexity and the installation cost of system wiring are reduced due to the reduction of the REC-RE interfaces.
Carry out two
Fig. 4 is a schematic diagram of a wireless device controller according to an embodiment of the present invention.
The embodiment further includes, on the basis of the first embodiment: a data distribution/aggregation module 404. The present embodiment takes the system connection manner of fig. 3B as an example. The data distribution/aggregation module in this embodiment is configured to:
receiving first data from RE305 transmitted through wireless device controller-wireless device interface module 307;
distributing a part of the first data to REC _ 1301 and distributing a part of the first data to REC _ 2302;
receiving second data including data from REC _2302 transmitted through the cascade interface module 309; and
the second data and the data transmitted by REC _ 1301 to RE305 are aggregated into third data, and the third data is transmitted to RE305 through radio device controller-radio device interface module 307.
The data aggregation forms in the embodiments of the present invention are various, and may be: the data from different RECs carry different address or label information, and the data distribution/aggregation module queues the data from different RECs according to a certain rule, and then gathers the data into a queue to be transmitted to the RE. In the embodiment, the data distribution process is the inverse process of the data aggregation process, and the data distribution/aggregation module receives the data transmitted by the RE, and divides one path of data into two or more paths of data according to different addresses or label information carried in the data and transmits the two or more paths of data to corresponding different RECs.
EXAMPLE III
Fig. 5 is a schematic diagram of a wireless device controller according to an embodiment of the present invention.
In this embodiment, on the basis of the second embodiment, the data processing module 504 is further configured to: receiving a portion of the first data distributed to the REC _ 1301; and performs data processing, and transmits the data-processed data to the RE305 through the data distribution/aggregation module 404.
In 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. A data processing function failure does not affect the data distribution/aggregation function. For example, when the data processing module 504 of REC _ 1301 fails, as long as the data distribution/aggregation module 404 of REC _ 1301 works normally, the normal communication between the RE305 and REC _2302 is not affected.

a data aggregation module 604 for aggregating the second data and the data transmitted by the wireless device controller 301 to the wireless device 305 into third data and transmitting the third data to the wireless device 305 through the wireless device controller-wireless device interface module 307.
The present embodiment can be regarded as that, on the basis of the second or third embodiment, the data distribution/aggregation module 404 is subdivided into: a first data receiving module 601, a second data receiving module 602, a data distributing module 603 and a data converging module 604. The above description is based on functional description, and various combinations of functional modules are possible in specific implementations. For example, the following steps: the first data receiving module 601 and the data distributing module 603 are designed as one functional module, and the second data receiving module 602 and the data aggregating module 604 are designed as one functional module.

EXAMPLE seven
The present embodiment provides a wireless communication system, and reference may be made to fig. 3A and 3B.
The wireless communication system in the present embodiment includes: a radio device controller, at least one multimode radio device, and at least one other radio device controller as described in any of the preceding embodiments one through six. The wireless equipment controller is connected with at least one multimode wireless equipment; the wireless device controller is connected to at least one other wireless device controller. And, the multi-mode wireless device communicates with the at least one other wireless device controller via the wireless device controller.
Example eight
The present embodiment provides a communication data transmission method, which is applied to a wireless communication system, where the wireless communication system includes: a radio device controller, at least one multimode radio device, and at least one other radio device controller as described in any of the preceding embodiments one through six. The method comprises the following steps: data for the interaction of the multimode wireless device with the at least one further wireless device controller is transmitted via the wireless device controller as described in any of the first to sixth embodiments above.
The present embodiment provides a communication data transmission method, which may further include:
receiving first data transmitted by the wireless device controller and the multimode wireless device;
distributing a portion of the first data to the wireless device controller and to the at least one other wireless device controller and to the portion of the first data;

and aggregating the second data and the data transmitted to the wireless device by the wireless device controller into third data, and transmitting the third data to the wireless device.
In the above embodiments, the shared physical link (311) to which the RE is connected with the multiple RECs may be an optical fiber or a cable. Typically, optical fibers are used for long distance connections and electrical cables are used for short distance connections.
In the above embodiments, the cascade interface (309) in the REC may be a panel interface or a backplane interface. Generally, the backplane interface does not require separate wiring, and the panel interface requires wiring. When the distance between the two RECs is longer, optical fiber wiring can be used; when the distance is short, cable wiring may be used. For example: when the two RECs are positioned in the same machine frame, or the same machine box, or the same cabinet, the cascade interface can be a back plate interface or a panel interface; when the two RECs are located in different subracks, or different cabinets, the cascading interface may be a panel interface.

The different RECs (301, 302, 303) share the physical bandwidth of this physical link to the RE, for example: the bandwidth on the physical link 311 may simultaneously carry multiple CPRI interface information. Compared with the mode that RE is respectively connected with REC, the solution of the implementation reduces the transmission cost, the number of REC-RE interfaces of RE is greatly reduced, and the complexity and the installation cost of system wiring are reduced due to the reduction of the REC-RE interfaces.
