Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular, to a communication device, a communication method, a communication equipment, and a passive optical fiber network. Background Art

[0002] The access network (RAN) in the traditional network architecture mainly includes: indoor baseband unit (BBU), radio remote unit (RRU) and antenna (AU). In the 5G scenario, the transmission signal frequency increases, and the bandwidth and number of channels also increase significantly. Multiple BBUs are concentrated in a central office (CO), and RRUs are deployed on remote signal towers or poles. Each BBU in C0 is connected to the RRU through one or more optical fibers. This deployment scheme is called a centralized radio access network (CRAN). When the CRAN deployment scheme is adopted, the RRU is not inside the central office, but is deployed on a remote signal tower. The distance between the RRU and the AU is closer, and the two can be integrated into a large-scale active antenna unit (AAU).

[0003] Usually, in actual application scenarios, RRUs are mostly deployed through traditional macro stations (such as tower stations). However, there are a large number of scenarios where it is difficult to deploy traditional macro stations. Taking the ancient town scenic area as an example, due to the age of its buildings, limited load-bearing capacity, small installation space, and high requirements for the beautification of the deployed equipment, it is difficult to deploy traditional macro stations. Based on the above reasons, pole micro stations (such as pole micro station EasyMacro, pole micro station BookRRU) have gradually been adopted to implement the deployment of RRU in scenarios such as commercial streets, residential areas, and squares. Pole micro stations are usually implemented using coverage solutions outside residential areas or coverage solutions inside residential areas. Among them, the coverage solution outside residential areas deploys pole micro stations outside residential areas so that the signal coverage range can enclose residential areas, thereby improving the signal coverage of residential areas. However, the pole micro station is deployed outside the residential area, and the signal needs to pass through the wall multiple times (each time the wall is passed through, a certain degree of loss is generated), which has a high loss, and the coverage range of the pole micro station is limited, so the indoor depth of the signal coverage of this solution is insufficient. The residential coverage solution deploys pole micro-stations inside residential areas, which can improve the coverage depth of the signal. However, since the RRU and BBU (i.e. pole micro-station) need to be connected by optical fiber, this solution requires the deployment of optical fiber, which is difficult to construct (for example, the deployment of optical fiber in old communities requires breaking ground) and has high deployment costs. Summary of the invention

[0004] The present application provides a communication device, a communication method, a communication equipment and a passive optical fiber network, which can parse a message from a received signal corresponding to a communication protocol, convert it into a signal corresponding to another communication protocol and output it.

[0005] In a first aspect, a communication device is provided. The communication device includes: a first interface, a processing circuit, a PON circuit, and a second interface; the processing circuit is coupled to the first interface and the PON circuit respectively, and the PON circuit is coupled to the second interface; the first interface is used for a communication device, specifically for receiving a first signal transmitted by the communication device, and parsing a first message from the first signal, the first message including a message of a first communication protocol; the processing circuit is used to convert the first message into a second message, the second message including a message of a second communication protocol; the PON circuit is used to convert the second message into a second signal; the second interface is used to couple a passive optical fiber network, specifically for transmitting the second signal to the passive optical fiber network.

[0006] Then, the communication device in the above scheme can parse the message of the first communication protocol from the signal received from the communication device, and then convert the parsed message into a new message including the message of the second communication protocol, and convert the new message into a corresponding signal and output it to the passive optical fiber network. Specifically, the communication device in the scheme can convert the message of the communication protocol corresponding to the communication device into the message of the communication protocol corresponding to the passive optical fiber network, so as to realize the protocol conversion of the message. Generally speaking, the communication devices mainly realize signal transmission through cables or wireless means, while the passive optical fiber network realizes signal transmission through optical fiber as the transmission medium. Therefore, the transmission medium of the communication device and the passive optical fiber network is different, and the corresponding communication protocols are different, and signal transmission cannot be realized. Then, through the communication device in the above scheme, the message in the signal transmitted by the communication device can be converted into the message in the signal transmitted by the passive optical fiber network through the communication protocol conversion, so that the communication device and the passive optical fiber network can carry out signal transmission, realize communication, and improve the quality and efficiency of signal transmission. Usually, the passive optical fiber network has completed the deployment of the corresponding network architecture. Furthermore, through this solution, signal transmission between communication devices can be achieved by relying on the existing passive optical fiber network architecture, without the need to deploy more equipment and cables, with higher compatibility and the ability to effectively reduce the deployment cost of the communication network.

[0007] In a possible implementation, the first communication protocol and the second communication protocol are different.

[0008] Then, the above scheme can convert the message of one communication protocol into the message of another communication protocol, and realize the communication protocol conversion of the message. Based on the message that has completed the communication protocol conversion, signal transmission can be realized between the devices or networks corresponding to different communication protocols. At the same time, the signal transmission between two different devices or networks can be realized by relying on the network architecture corresponding to one of the devices or networks. Then, through the above scheme, first of all, the message conversion between two different communication protocols can be completed, so that signal transmission can be realized between the devices or networks corresponding to the two communication protocols, and the signal transmission of the two communication protocols can be realized based on one network architecture, which improves the compatibility of the devices or networks.

[0009] In a possible implementation, the first communication protocol includes: a universal public radio interface protocol; the second communication protocol includes: an Ethernet protocol.

[0010] Then, the above scheme can convert the message of the common public wireless interface protocol into the message of the Ethernet protocol, and realize the communication protocol conversion of the message. Furthermore, through the equipment or network corresponding to the public wireless interface protocol and the Ethernet protocol, the signal transmission between the two communication protocols can be realized. At the same time, since the public wireless interface protocol and the Ethernet protocol respectively include different equipment or networks, through the above scheme, the signal transmission of the public wireless interface protocol and the Ethernet protocol can be realized by relying on any network architecture corresponding to the public wireless interface protocol or the Ethernet protocol. Then, through the above scheme, the message conversion between the public wireless interface protocol and the Ethernet protocol can be completed, so that the signal transmission between the two communication protocols can be realized, and the signal transmission of the two communication protocols can be realized based on a network architecture in the public wireless interface protocol or the Ethernet protocol.

[0011] In a possible implementation, the communication device includes an indoor baseband unit or a radio remote unit.

[0012] Then, the above solution can be applied to indoor baseband units or radio remote units. Usually, the architecture of the access network includes indoor baseband units and radio remote units, and the two need to be connected by optical fiber to achieve signal transmission. Then, through the above solution, the signal transmission between the indoor baseband unit and the radio remote unit can be achieved by relying on the network architecture of the passive optical fiber network, without the need to deploy optical fiber, reducing the construction difficulty or deployment cost. For example, the deployment of optical fiber often requires breaking ground in a residential area, which is difficult and costly.

[0013] In a possible implementation, the communication device includes an indoor baseband unit, and the PON circuit is specifically used to perform an optical line terminal function to convert the second message into a second signal.

[0014] Then, the above scheme can be applied to the indoor baseband unit, and the PON circuit in the communication device performs the optical line terminal function to convert the message into a corresponding signal. For example, when the communication device has completed the communication protocol conversion of the message in the signal sent by the indoor baseband unit, the message of the public wireless interface protocol parsed from the signal sent by the indoor baseband unit is converted into a message of the Ethernet protocol. However, the message cannot be directly output to the passive optical fiber network, and it is difficult to achieve signal transmission between the communication device and the passive optical fiber network. Therefore, it is necessary to perform the optical line terminal function through the PON circuit in the communication device, convert the message of the Ethernet protocol into a corresponding signal, and then output it to the passive optical fiber network, so as to realize the signal transmission between the two communication protocols. Among them, the optical line terminal function performed by the PON circuit includes: supporting point to multiple point (P2MP) transmission technology, controlling, managing and ranging the user terminal equipment (for example, performing uplink channel bandwidth scheduling on the user terminal equipment). Then, the above scheme can convert the converted Ethernet protocol message into a corresponding signal through the optical line terminal function of the PON circuit in the communication device, so as to realize the signal transmission between the two communication protocols.

[0015] In a possible implementation, the communication device includes a radio remote unit, and the PON circuit is specifically used to perform an optical network unit function and convert the second message into a second signal.

[0016] Then, the above scheme can be applied to the radio remote unit, and the optical network unit function is executed by the PON circuit in the communication device to convert the message into the corresponding signal. For example, when the communication device has completed the communication protocol conversion of the message in the signal sent by the radio remote unit, the message of the public wireless interface protocol parsed in the signal sent by the radio remote unit is converted into a message of the Ethernet protocol. However, the message cannot be directly output to the passive optical fiber network, and it is difficult to achieve signal transmission between the communication device and the passive optical fiber network. Therefore, it is necessary to execute the optical network unit function through the PON circuit in the communication device, convert the message of the Ethernet protocol into the corresponding signal, and then output it to the passive optical fiber network, so as to achieve signal transmission between the two communication protocols. Then, the above scheme can convert the converted Ethernet protocol message into the corresponding signal through the optical network unit function of the PON circuit in the communication device, so as to achieve signal transmission between the two communication protocols. In addition, only by multiplexing the corresponding network architecture, point-to-point signal transmission is usually achieved. For example, a BBU can perform point-to-point signal transmission with an RRU by multiplexing the corresponding network architecture. However, the communication device based on the above scheme can realize point-to-multipoint transmission by deploying a communication device provided by the above scheme on the BBU side to perform the optical line terminal function, and deploying multiple communication devices provided by the above scheme on the RRU side to perform the optical network unit function. That is, one BBU can perform point-to-multipoint signal transmission with multiple RRUs by multiplexing the corresponding network architecture.

[0017] In a possible implementation, the communication device further includes: a control circuit; the control circuit is connected to the processing circuit, and is used to control the communication device to implement one or more of the following functions: startup, software loading, and upgrade.

[0018] Then, in the above scheme, the startup, software loading, and upgrading of the communication device can also be controlled by the control circuit connected to the processing circuit. In one possible implementation, signal transmission is required between the communication device and the passive optical fiber network only in a fixed time period. Then, through the control circuit in the communication device, the communication device can be controlled to start in the fixed time period to ensure that signal transmission can be performed between the communication device and the passive optical fiber network, and energy consumption is effectively reduced. For another example, based on the update of the communication protocol, the technical update of the communication device, etc., the communication device also needs to load and upgrade the corresponding software. Then, through the control circuit in the communication device, the communication device can be controlled to load and upgrade the corresponding software to ensure the compatibility of the communication device.

[0019] In a second aspect, a communication device is provided. The communication device includes: a first interface, a processing circuit, a PON circuit, and a second interface; the processing circuit is coupled to the first interface and the PON circuit respectively, and the PON circuit is coupled to the second interface; the second interface is used to couple with a passive optical fiber network, specifically to receive a second signal transmitted by the passive optical fiber network, and to parse a second message from the second signal, the second message including a message of a second communication protocol; the processing circuit is used to convert the second message into a first message, the first message including a message of a first communication protocol; the PON circuit is used to convert the first message into a first signal; the first interface is used to couple with a communication device, specifically to transmit the first signal to the communication device.

[0020] Then, the communication device in the above scheme can parse out the message of the second communication protocol included in the signal received from the passive optical fiber network, and then convert the parsed message into a new message including the message of the first communication protocol, and convert the new message into a corresponding signal and output it to the communication device. Specifically, the communication device in this scheme can convert the message corresponding to the communication protocol of the passive optical fiber network into the message of the communication protocol corresponding to the communication device, so as to realize the protocol conversion of the message. Since the transmission medium of the communication device and the passive optical fiber network is different, the communication protocols corresponding to each of them are different, and usually it is impossible to directly transmit signals. Then, through the communication device in the above scheme, it is possible to convert the message in the signal transmitted by the passive optical fiber network into the message in the signal transmitted by the communication device through the communication protocol conversion, so that signal transmission can be realized between the communication device and the passive optical fiber network.

[0059] The present application will present various aspects, embodiments or features around a system that may include multiple devices, components, modules, etc. It should be understood and appreciated that each system may include additional devices, components, modules, etc., and / or may not include all devices, components, modules, etc. discussed in conjunction with the accompanying drawings. In addition, a combination of these schemes may also be used. It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific manner.

[0060] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0061] Optical fiber communication system has become the mainstream communication system at present. Optical fiber communication system usually includes core network (CN), access network (RAN), etc. Among them, the access network RAN ​​in the traditional network architecture mainly includes: indoor baseband unit BBU, radio remote unit RRU and antenna AU.

[0062] For example, refer to Figure 1 As shown, an embodiment of the present application provides a schematic diagram of a deployment scheme of an access network. In this architecture, each computer room is equipped with a BBU and an RRU connected by a coaxial cable, and the transmission signal is sent by the RRU to the AU wirelessly. This RAN deployment scheme is called a distributed radio access network (DRAN).

[0063] When multiple BBUs need to be deployed, operators deploy multiple BBUs separately, which will lead to higher deployment costs (such as site rental). Therefore, multiple BBUs need to be concentrated in a central office (CO) to reduce deployment costs. The RRU is deployed on a remote signal tower. Each BBU in the C0 is connected to the RRU through one or more optical fibers. This RAN deployment solution is called a centralized radio access network (CRAN). When the CRAN deployment solution is adopted, since the RRU is not inside the central office, but is deployed on a remote signal tower, the distance between the RRU and the AU is closer, and the two can be integrated into a large-scale active antenna unit (AAU). The centralized deployment of the AAU effectively reduces the deployment cost.

[0064] For example, refer to Figure 2 As shown, an embodiment of the present application provides a schematic diagram of a CRAN deployment solution. Specifically, multiple BBUs (BBU0-BBUn) are centrally deployed in a CO, and RRUs are deployed on remote signal towers very close to AUs (RRUs and AUs are integrated into AAU modules). Each BBU is connected to the RRU via one or more optical fibers, that is, each BBU is connected to the AAU via one or more optical fibers. For example, referring to Figure 2 As shown, BBU0 is connected to AAU0, AAU1, and AAU2 through three optical fibers respectively; BBUn is connected to AAUn-2, AAUn-1, and AAUn through passive wavelength division multiplexing (WDM).

[0065] Among them, RRU is usually deployed through traditional macro base stations (such as tower base stations) in actual application scenarios, but there are still many scenarios that are not suitable for deploying traditional macro base stations. For example, the buildings in ancient town scenic spots are very old, have limited load-bearing capacity, small installation space, and have high requirements for the beautification of the deployed equipment, so traditional macro base stations are difficult to deploy. This will make it difficult to deploy RRU, the signal coverage is poor, and the user experience is affected.

[0066] For example, refer to Figure 3 As shown, the embodiment of the present application provides a statistical diagram of signal coverage. Specifically, Figure 3 (1) is a distribution statistics diagram of signal coverage black spots (i.e., signal blind spots), including: rural towns (sector-shaped area 1 in the figure), residential areas (sector-shaped area 2 in the figure), roads (sector-shaped area 3 in the figure), schools (sector-shaped area 4 in the figure), commercial centers (sector-shaped area 5 in the figure), industrial parks (sector-shaped area 6 in the figure), transportation hubs (sector-shaped area 7 in the figure), and other scenes (sector-shaped area 8 in the figure). Among them, residential areas and rural towns are the two scenes with the largest proportion of signal coverage black spots, and are the main sources of signal coverage black spots. Figure 3 (2) is the statistics of user complaints about mobile Internet access in various scenarios collected by operators. Among them, home is the scenario where most complaints are caused by mobile Internet users, accounting for 60.60%. Elevators / underground garages are also the scenarios where most complaints are caused by mobile Internet users, accounting for 29.76%. Other scenarios where most complaints are caused by mobile Internet users account for 9.64%.

[0067] Based on the above reasons, since the pole micro-station is small in size and easy to deploy, it has gradually been adopted to deploy RRU in residential areas, commercial streets, squares and other scenes. Usually, the pole micro-station can adopt the coverage plan outside the residential area or the coverage plan inside the residential area.

[0068] For example, refer to Figure 4 As shown, the present application embodiment provides a schematic diagram of a deployment scenario of a pole microstation. Figure 4 As shown, the pole microstation includes: a spotlight and a spotlight antenna (i.e. Figure 4 (1) in), easy macro (i.e. Figure 4 (2) in the above), pole microstation bookRRU (i.e. Figure 4 (3) in the figure.

[0069] For example, refer to Figure 5 As shown, the present application embodiment provides a schematic diagram of a pole micro-station coverage solution outside a residential area. Figure 5 As shown, the coverage scheme includes four pole micro-stations deployed outside the residential area, namely pole micro-station 1, pole micro-station 2, pole micro-station 3 and pole micro-station 4. Each pole micro-station has its corresponding signal coverage range (refer to Figure 5 Among them, by deploying pole micro-stations outside residential areas, the signal coverage range can be extended to surround the residential areas, thereby improving the signal coverage of the residential areas.

[0070] However, since the pole micro-station in the above solution is deployed outside the residential area, the signal needs to pass through the wall multiple times (each time passing through the wall, a certain degree of loss occurs), resulting in high loss. At the same time, the signal coverage range of the pole micro-station is limited, and it is difficult to achieve signal coverage in the area inside the residential area or the signal coverage is often poor. Therefore, the above solution is difficult to achieve full signal coverage in the residential area, and the indoor depth of the signal coverage of this solution is insufficient.

[0071] Combination Figure 2 The architecture shown is exemplary, referring to Figure 6 As shown, the embodiment of the present application provides a schematic diagram of a coverage solution of a pole micro-station in a residential area. The coverage solution deploys RRU (pole micro-station) based on the communication network architecture of CRAN to realize the networking of BBU and RRU. Figure 6 As shown, the BBU deployed in the central computer room will be connected to the input end of the first-level splitter through the trunk optical fiber, one output end of the first-level splitter is directly connected to a residential area through the wiring optical fiber, and the other output end of the first-level splitter is connected to the input end of the second-level splitter through the wiring optical fiber, and the output end of the second-level splitter is connected to the pole micro station in another residential area through the home optical fiber. Optionally, the above-mentioned splitter equipment includes a splitter and an optical cable junction box.

[0072] Combination Figure 6 As shown, the optical signal sent by the BBU can be transmitted along the trunk optical fiber to the input end of the first-level optical splitter, where a part of the optical signal is transmitted through an output end of the first-level optical splitter along the distribution optical fiber to a residential area, and the other part of the optical signal is transmitted through another output end of the first-level optical splitter along the distribution optical fiber to the input end of the second-level optical splitter, and then transmitted through the output end of the second-level optical splitter along the household optical fiber to the pole micro station in another residential area. It is not difficult to understand that here only the optical signal transmission process in the downstream direction is taken as an example, and the upstream direction is similar, so it will not be repeated here.

[0073] In this way, on the one hand, the above solution has a simple structure and does not require the addition of additional equipment. In addition, the optical fiber used between the BBU and the RRU can be used for point-to-point transmission to achieve optical fiber direct connection. On the other hand, by deploying the pole micro-station inside the residential area, the above solution can make the signal coverage range of the pole micro-station cover the residential area, thereby improving the coverage depth of the signal.

[0074] However, since the RRU and BBU (i.e., the pole microstation) need to be connected via optical fiber, this solution requires the deployment of optical fiber, which is difficult to construct (for example, the deployment of optical fiber in old communities requires breaking ground) and has a high deployment cost. Figure 7 As shown, the embodiment of the present application provides a deployment scenario diagram of a pole micro-station coverage solution in a residential area. Figure 7As shown in (1), the above scheme (refer to Figure 6 As shown in the figure, it is usually necessary to deploy optical fiber to connect BBU and RRU. Deploying optical fiber in old residential areas requires breaking ground, and the property management requires that roads and walls not be broken, which requires constant negotiation and makes construction difficult. New residential areas generally have cable ducts, but they usually belong to the developer, which also requires corresponding negotiation and makes optical fiber difficult to deploy. Figure 7 As shown in (2), it is necessary to break ground and dig to lay the optical fiber.

[0075] For example, refer to Figure 8 As shown, the embodiment of the present application provides a statistical diagram of the deployment cost of an RRU coverage solution. Figure 8 The horizontal axis is the deployment method, and the vertical axis is the deployment cost. The deployment methods include traditional macro base stations and pole micro base stations. Figure 8 As shown in the figure, the deployment cost of pole micro-stations is much lower than that of traditional macro-stations, about half of that of traditional macro-stations. Compared with the deployment of traditional macro-stations, in scenarios where there are pipelines and wiring space in the community, the deployment cost can be greatly reduced by deploying pole micro-stations. However, in scenarios where there are no pipelines and wiring space in old communities, it is necessary to break ground and lay optical fibers, which leads to a significant increase in the deployment cost of pole micro-stations.

[0076] Usually, based on Figure 1 In the architecture shown, the access network is accessed by fiber to the x (FTTx), which is also called optical access network (OAN). Fiber access methods include fiber to the home (FTTH) and fiber to the building (FTTB). Among them, the common ones that can achieve fiber access are passive optical networks (PON).

[0077] Then, the network architecture of the deployed passive optical fiber network can be used to realize the deployment of the pole micro-station. Fig. 9 As shown, an embodiment of the present application provides a schematic diagram of a passive optical network (PON) 10 networking. Specifically, taking the downstream direction as an example, the PON 10 includes an optical line terminal OLT arranged in a central control station, an optical network terminal ONT arranged on the user side, and an optical network unit ONU. Among them, the ONT and the different positions arranged on the user side implement similar functions.

[0078] In one possible implementation, combining Fig. 9As shown, PON 10 also includes: an optical distribution frame (ODF) arranged in the central control station, the ODF is connected to the OLT, and is used for the termination and distribution of the trunk optical cable at the local end of the optical fiber communication system, which can conveniently realize the connection, distribution and scheduling of the optical fiber line. Optionally, PON 10 also includes: an optical cable junction box / fiber distribution terminal box (fiber distribution terminal, FDT) connected to the central control station, which is used to provide optical cable termination and jumper for the trunk layer optical cable and the distribution layer optical cable. Optionally, PON 10 also includes: a junction box connected to the FDT, and a passive optical power splitter (splitter, SPL) connected between the junction box and the ONT and ONU for coupling, branching and distributing optical signals. Of course, the passive optical power splitter can also be replaced by an optical splitter (also called a splitter), an optical splitter and other devices with similar functions.

[0079] The devices in the passive optical network are connected by optical fibers, and these optical fibers can transmit both uplink optical signals and downlink optical signals. Fig. 9 The passive optical fiber network shown is used as an example for explanation, and the type and number of devices included in the passive optical fiber network should not be limited thereto.

[0080] Specifically, taking the downstream direction as an example, in PON 10, the optical signal sent by OLT is transmitted along the optical fiber to ODF, the input end of ODF receives the optical signal, the optical signal is transmitted along the optical fiber to the input end of FDT through the output end of ODF, and is transmitted along the optical fiber to the junction box through the output end of FDT, wherein a part of the optical signal is transmitted along the optical fiber to the input end of optical beam splitter 1, and is transmitted along the optical fiber to ONU through the output end of optical beam splitter 1, and another part of the optical signal is transmitted along the optical fiber to the input end of optical beam splitter 2, and is transmitted along the optical fiber to ONT through the output end of optical beam splitter 2.

[0081] For ease of description, the transmission process of an optical signal in the downstream direction is taken as an example. In other embodiments, the ONU or ONT may also generate an optical signal sent to the OLT in the upstream direction, and the process of the ONU or ONT generating the optical signal and sending the optical signal to the OLT is not repeated here.

[0082] based on Fig. 9 The architecture shown can utilize the network architecture of the deployed optical fiber transmission network (e.g., passive optical fiber network) to realize the deployment of pole micro-stations, so that BBU and RRU can be connected through corresponding devices (e.g., passive optical power splitters) and devices (e.g., 10G or 25G optical modules, etc.). Fig.10As shown, an embodiment of the present application provides a schematic diagram of an optical fiber communication network 20. The optical fiber communication network 20 includes: a BBU, two passive optical power splitters (refer to Fig.10 SPL-1, SPL-2), five 25G optical modules (refer to Fig.10 25G optical module 1, 25G optical module 2, 25G optical module 3, 25G optical module 4 and 25G optical module 5), three pole micro stations (refer to Fig.10 Pole microstation 1, pole microstation 2 and pole microstation 3) and passive optical fiber network (refer to Fig. 9 The PON 10 shown in FIG. 10 is a PON 10 in which each of the above devices (or modules) is connected via optical fibers. Fig.10 The optical fiber communication network 20 is shown as an example, and the types of communication devices included in the optical fiber communication network should not be limited thereto. In a possible implementation, the above-mentioned 25G optical module may also be other types of optical modules, such as a 10G optical module.

[0083] Specific, combined Fig.10 As shown, the BBU is connected to a 25G optical module 1, which is connected to the input end of SPL-1 through a trunk optical fiber, the output end of SPL-1 is connected to the input end of PON 10 through an optical fiber, and the output end of PON 10 is connected to a 25G optical module 2 through an optical fiber, wherein the 25G optical module 2 is connected to the pole micro station 1. The BBU is also connected to a 25G optical module 3, which is connected to the input end of the passive optical power splitter SPL-2 through a trunk optical fiber, and the output end of SPL-2 is respectively connected to 25G optical module 4 and 25G optical module 4 through optical fibers, wherein the 25G optical module 4 is connected to the pole micro station 2, and the 25G optical module 5 is connected to the pole micro station 3.

[0084] Taking the downlink direction as an example, the optical signal sent by the BBU is processed by the corresponding algorithm executed by the 25G optical module (for example, the optical digital signal processor (oDSP) algorithm), and then transmitted along the trunk optical fiber through SPL-1 to the input end of PON 10, and then transmitted from the output end of PON 10 along the optical fiber to the 25G optical module 2, and then sent to the pole micro station 1 after being processed by the corresponding algorithm executed by the 25G optical module 2. Among them, the signal transmission process in the uplink direction is similar to the signal transmission process in the downlink direction, which will not be repeated here. For the sake of convenience, only the optical signal transmission process between the BBU and the pole micro station 1 in the downlink direction is taken as an example here, and it should not be used to limit other optical fiber transmission processes in the optical fiber communication network 20.

[0085] It is not difficult to understand that Fig.10The trunk optical fiber in can reuse the currently deployed optical fiber, and PON 10 can also reuse the deployed PON network (such as PON 10). Then, the above solution can effectively reduce the number of optical fibers in the communication network by utilizing the deployed network architecture, thereby reducing costs and realizing low-cost deployment of pole micro stations.

[0086] Although, in principle, the above technical solution can utilize the deployed network architecture to realize the deployment of pole microstations, thereby reducing costs to a certain extent. However, the implementation of optical modules (such as 25G optical modules) still faces many difficulties. For example, it is difficult for optical modules to implement corresponding algorithms (such as oDSP algorithms) in software, and there are no chips of suitable size and logic in hardware. At the same time, there are problems with the heat dissipation of optical modules. The implementation of optical modules often requires customized dedicated chips, which is very difficult to implement and has high costs. Therefore, the above solution is too dependent on hardware, difficult to implement and costly, and difficult to promote.

[0087] Based on the above, for example, refer to Fig.11 As shown, the present application proposes a schematic diagram of a communication device. Fig.11 As shown, the communication device can be called a communication device (common public radio interface over ethernet, COE). This is only an example here, and the structure of the communication device should not be limited by this. Through the communication device, it is possible to parse the message from the signal corresponding to the received communication protocol, convert it into a signal corresponding to another communication protocol and output it. Fig.11 As shown, the communication device includes: a first interface ( Fig.11 Interface 701 in), processing circuit ( Fig.11 702 in), PON circuit ( Fig.11 703) and the second interface ( Fig.11 wherein the processing circuit 702 is coupled to the interface 701 and the PON circuit 703, the PON circuit 703 is coupled to the interface 704, and the interface 701 is used to couple the communication device (eg Fig.11 705 in ), interface 704, for coupling a passive optical network (e.g. Fig.11 PON 706 in.

[0088] In a possible implementation, the PON 706 can utilize Fig. 9 In some other examples, the PON 706 may also be other passive optical networks. Fig.11 The communication device shown is taken as an example, and the architecture of the passive optical network to which the communication device is connected should not be limited thereto.

[0089] It is not difficult to understand that the above-mentioned communication device COE can also be deployed at different locations of the communication network, so the interface 701 can also be connected to other communication devices. Optionally, the communication device 705 includes a BBU or an RRU. Optionally, the interface 701 of the communication device COE is connected to the BBU, and the PON circuit 703 will perform the optical line terminal (OLT) function to convert the first message into a first signal. In one possible implementation, the interface 701 of the COE is connected to the RRU, and the PON circuit 703 will perform the optical network unit (ONU) function to convert the second message into a second signal.

[0090] Optional, combined Fig.11 As shown, the communication device further includes a control circuit 707. The control circuit 707 is connected to the processing circuit 702 and is used to control the communication device to implement one or more of the following functions: startup, software loading, and upgrade.

[0091] Based on the above communication device COE, for example, refer to Fig.12 As shown, an embodiment of the present application provides a schematic diagram of a communication network. Fig.12 As shown, the communication device connected to the interface 701 of the communication device COE is a BBU, and the interface 704 is connected to the PON 10. Specifically, the communication device COE is deployed in the central office CO, connected to the BBU in the CO, and also deployed near the RRU, connected to the RRU.

[0092] In the downlink direction, in COE 1, interface 701 receives a signal (referred to as a first signal) transmitted by BBU, and parses a corresponding message (referred to as a first message) from the first signal, the first message including a message of the first communication protocol; processing circuit 702 converts the parsed first message into a new message (referred to as a second message), the second message including a message of the second communication protocol; PON circuit 703 performs an OLT function, converts the second message into a corresponding signal (referred to as a second signal); interface 704 transmits the second signal to PON 10. The second signal is transmitted to COE 2 after passing through PON 10. In COE 2, interface 704 receives the second signal transmitted by PON 10, and parses a second message from the second signal, the second message including a message of the second communication protocol. Processing circuit 702 converts the parsed second message into a first message, the first message including a message of the first communication protocol. PON circuit 703 performs an ONU function, converts the first message into a first signal. Interface 701 transmits the first signal to RRU. in, Fig.12 The signal transmission process of PON 10 can be referred to Fig. 9For the convenience of explanation, the signal transmission process in the downlink direction is taken as an example here, and the signal transmission process in the uplink direction is similar to the signal transmission process in the downlink direction, which will not be described in detail here.

[0093] In a possible implementation, optionally, the first communication protocol and the second communication protocol are different, wherein the first communication protocol includes: a common public radio interface (CPRI) protocol, and the second communication protocol includes: an Ethernet (Ethernet, Eth) protocol.

[0094] Usually, the communication network deployed by the communication equipment has a different communication protocol from the passive optical network. Then, through the communication device in the above scheme, it is possible to convert the message in the signal transmitted by the communication equipment into the message in the signal transmitted by the passive optical network through the communication protocol conversion, so that the communication equipment and the passive optical network can transmit signals to achieve communication, thereby improving the quality and efficiency of signal transmission. In addition, since the passive optical network has usually completed the deployment of the corresponding network architecture, the signal transmission between communication equipment and communication equipment through this scheme can be achieved by relying on the existing network architecture of the passive optical network, without the need to deploy more equipment and cables, with higher compatibility and the ability to effectively reduce the deployment cost of the communication network.

[0095] It should be noted that Fig.11 and Fig.12 This is only one possible implementation and deployment method of the communication device COE provided in the embodiments of the present application. In other examples, there are other possible implementation and deployment methods of the above communication device COE.

[0096] For example, refer to Fig.13 As shown, a schematic diagram of a communication network is provided. Specifically, Fig.13 As shown in (1), two communication devices COE (i.e., COE 1 and COE 2) are newly deployed between the BBU and the RRU. The first interface of the communication device COE1 is connected to the BBU, and the second interface of the communication device COE 1 is connected to the PON network; the first interface of the communication device COE 2 is connected to the RRU, and the second interfaces of COE 1 and COE 2 are both connected to the PON network (including passive communication equipment), wherein the connection media corresponding to the above connection relationships are optical fibers. The function of the communication device COE is implemented by a logic unit, and the OLT or ONU function of the PON circuit is implemented by a PON chip. In this way, the solution can use commonly used chips and logic devices, so that the communication device can be implemented at a low cost.

[0097] Combination Fig.13As shown in (2), a communication device COE 1 is newly deployed on the BBU side, and three communication devices COE (i.e., COE 2, COE 3, and COE 4) are newly deployed on the RRU side. Among them, the first interface of the communication device COE 1 is connected to the BBU, and the second interface of the communication device COE 1 is connected to the PON network; the second interfaces of the communication devices COE 2, COE 3, and COE 4 are all connected to the PON network (including passive communication equipment), and the first interfaces of the communication devices COE 2, COE 3, and COE 4 are all connected to the RRU, wherein the connection media corresponding to the above connection relationships are all optical fibers. In this way, the scheme deploys a communication device COE on the BBU side and deploys a communication device COE on any RRU, so that the communication network can support point-to-multipoint networking.

[0098] Combination Fig.13 As shown in (3), a communication device COE 1 is newly deployed on the BBU side, and two communication devices COE (i.e., COE 2 and COE 3) are newly deployed on the RRU side. Among them, the communication device COE 1 is implemented by adding an interface board to the BBU device, or integrating the PON function in the main control board of the BBU device. Communication devices COE 2 and COE 3 are implemented by integrating chips in the RRU device to support the PON function. Therefore, the above scheme does not require the addition of a communication device COE, and can provide a new implementation method of the communication device COE on the BBU side and the RRU side (adding an interface board on the BBU side and integrating chips on the RRU side), effectively reducing the difficulty of implementing the communication device COE. However, the above scheme requires the support of newly developed hardware. For example, the BBU side requires a newly developed interface board to support the PON function, and the RRU side requires the corresponding PON processing chip to be integrated.

[0099] Combination Fig.13 As shown in (4), a communication device COE 1 is newly deployed on the BBU side, and two communication devices COE (i.e., COE 2 and COE 3) are newly deployed on the RRU side. Among them, the communication device COE 1 is implemented by deploying one communication device COE. The communication devices COE 2 and COE 3 are implemented by deploying optical modules with integrated ONU functions. Then, the above scheme can provide a new implementation method of the communication device COE on the RRU side (through an optical module with ONU function), so that the implementation method of the communication device COE has more possibilities and can be flexibly deployed.

[0100] It should be noted that only Fig.13 Taking the architecture shown in the figure as an example, other possible implementations and deployments of the communication device are described, but the deployment location, implementation, etc. of the communication device should not be limited by this. Fig.13The architecture shown in (4) (i.e., the communication device COE on the RRU side can be implemented by an optical module with integrated ONU function) can be extended to consider integrating the 3rd generation partnership project (3GPP) cellular network with the optical modem in the home PON network (e.g. Fig.12 In this way, the appearance of the communication device COE is the form of an optical module, and it can be used to achieve deep coverage of indoor cellular networks, thereby specifically solving the problem of poor user voice experience and serious complaints caused by weak signal coverage of indoor cellular networks. In addition, this solution can avoid RRU site and solve power supply problems, simplifying the deployment of communication networks.

[0101] Of course, the 3GPP cellular network in the above solution can also be a communication network of other standards such as the global system for mobile communications (GSM), universal mobile telecommunications system (UMTS) or long term evolution (LTE). Fig.12 The architecture shown is exemplary, referring to Fig.14 As shown, a schematic diagram of a communication network is provided, wherein the communication device COE can also be extended to support the use of microwave equipment to provide a microwave wireless fronthaul link. Fig.14 The microwave device 1 shown includes a microwave module and a microwave antenna. Specifically, on the BBU side, a microwave device 1 is newly deployed, and the microwave device 1 is connected to the COE 1. On the RRU side, a microwave device 2 is newly deployed, and the microwave device 2 is connected to the COE 2. The deployed microwave devices form a microwave wireless fronthaul link.

[0102] Then, the extended functions provided by the above scheme include the following two functions: First, the above scheme can realize the load sharing function. For example, if the fronthaul bandwidth demand is high and the fronthaul bandwidth of the PON fronthaul link is occupied by the ONU, the microwave wireless fronthaul link formed by the newly deployed microwave equipment can provide the corresponding bandwidth. At the same time, the above scheme can also realize the backup function. For example, if a communication link in the communication network is interrupted (including the microwave wireless fronthaul link and the PON fronthaul link), the signal transmission can be guaranteed through another communication link, realizing the backup and replacement functions.

[0103] based on Fig.11The embodiment of the present application provides a communication method, which can parse a message from a received signal corresponding to a communication protocol and convert it into a signal corresponding to another communication protocol. Fig.15 As shown, a schematic diagram of a communication method is provided. Fig.15 , the communication method provided in the embodiment of the present application is described in detail. Fig.11 The communication method provided in the embodiment of the present application is described by taking the architecture shown as an example, but the communication method provided in the embodiment of the present application is not limited thereto. The communication method includes steps 901 to 905, and the communication method is applied to a communication device. The following specifically describes the communication method applied to a communication device as an example, and the specific description is as follows:

[0104] Step 901: Receive a first signal transmitted by a communication device.

[0105] Combination Fig.15 As shown, a first signal transmitted by a communication device is received. Specifically, in combination Fig.11 In the illustrated architecture, the interface 701 in the communication device COE receives a first signal transmitted by the communication equipment BBU.

[0106] Optionally, the communication equipment includes an indoor baseband unit and a radio remote unit.

[0107] Step 902: parse a first message from a first signal.

[0108] Combination Fig.15 As shown, the first message is parsed from the first signal. Specifically, Fig.11 In the illustrated architecture, the communication device COE parses a first message from a first signal, wherein the first message includes a message of a first communication protocol.

[0109] Step 903: Convert the first message into a second message.

[0110] Combination Fig.15 As shown, the first message is converted into the second message. Specifically, in combination Fig.11 In the illustrated architecture, the processing circuit 702 in the communication device COE converts the first message into a second message, wherein the second message includes a message of the second communication protocol.

[0111] Optionally, the first communication protocol and the second communication protocol are different. In a possible implementation, the first communication protocol includes: a universal public radio interface protocol, and the second communication protocol includes: an Ethernet protocol.

[0112] Step 904: Convert the second message into a second signal.

[0113] Combination Fig.15 As shown, the second message is converted into a second signal. Specifically, in combination Fig.11 In the illustrated architecture, the processing circuit 702 in the communication device COE converts the second message into a second signal.

[0114] In combination with step 901, in a possible implementation, the communication device includes an indoor baseband unit, and the PON circuit 703 in the communication device COE converts the second message into a second signal by executing the optical line terminal function. Optionally, the communication device also includes a radio remote unit, and the PON circuit 703 in the communication device COE converts the second message into a second signal by executing the optical network unit function.

[0115] Step 905: Transmit the second signal to the passive optical fiber network.

[0116] Combination Fig.15 As shown, the second signal is transmitted to the passive optical fiber network. Specifically, in combination Fig.11 In the illustrated architecture, the interface 704 in the communication device COE transmits the second signal to the passive optical network.

[0117] Generally speaking, communication devices mainly transmit signals through cables or wireless means, while passive optical fiber networks use optical fibers as transmission media to transmit signals. Therefore, the transmission media of communication devices and passive optical fiber networks are different, and their corresponding communication protocols are different, so signal transmission cannot be achieved. However, through the above-mentioned communication method, it is possible to convert the message corresponding to the communication protocol of the communication device into the message corresponding to the communication protocol of the passive optical fiber network, realize the protocol conversion of the message, and convert the new message into the corresponding signal and output it to the passive optical fiber network.

[0118] Then, through the communication method in the above scheme, the message in the signal transmitted by the communication device can be converted into the message in the signal transmitted by the passive optical fiber network through the communication protocol conversion, so that the communication device and the passive optical fiber network can transmit signals to achieve communication, thereby improving the quality and efficiency of signal transmission. Furthermore, since the passive optical fiber network has usually completed the deployment of the corresponding network architecture, the signal transmission between communication devices through this scheme can be achieved by relying on the existing network architecture of the passive optical fiber network, without the need to deploy more equipment and cables, with higher compatibility, and can effectively reduce the deployment cost of the communication network.

[0119] For example, refer to Fig.16As shown, an embodiment of the present application provides a schematic diagram of a communication device. The communication device may also be a module or chip in a communication device, and the communication device may also be a chip or a system on chip. The communication device includes: a transceiver unit 1601 and a processing unit 1602; the transceiver unit 1601 is used to receive a first signal transmitted by a communication device, and parse a first message from the first signal, wherein the first message includes a message of a first communication protocol, and is also used to transmit a second signal to a passive optical fiber network; the processing unit 1602 is used to convert the first message obtained by the transceiver unit 1601 into a second message, wherein the second message includes a message of a second communication protocol; and is also used to convert the second message into a second signal.

[0120] The transceiver unit 1601 is further used to execute the communication method described in step 901, step 902 and step 905; the processing unit 1602 is further used to execute the communication method described in step 903 and step 904. It can be understood that the communication device can directly refer to the above Fig.15 The description of the various functions and effects in the communication method shown will not be repeated here.

[0121] In a possible implementation, an embodiment of the present application further provides a communication device, which may be a chip or a chip system. The communication device includes: a processor and an interface circuit, and the processor is used to read instructions to execute the method in any of the above method embodiments.

And the transceiver is used to communicate with other devices / devices through a transmission medium.

[0125] Optionally, the communication device may also include one or more memories 1703 for storing program instructions and / or data. The memory 1703 is coupled to the processor 1702. The coupling in the embodiment of the present application is an indirect coupling or communication connection between devices, units or modules, which may be electrical, mechanical or other forms, and is used for information exchange between devices, units or modules. The processor 1702 may operate in conjunction with the memory 1703. The processor 1702 may execute program instructions stored in the memory 1703. Optionally, at least one of the one or more memories may be included in the processor.

[0126] The specific connection medium between the transceiver 1701, the processor 1702 and the memory 1703 is not limited in the embodiment of the present application. Fig.17 In the embodiment, the memory 1703, the processor 1702 and the transceiver 1701 are connected via a bus 1704. Fig.17 The connections between the other components are shown in bold lines, which are only for illustration and are not intended to be limiting. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Fig.17 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0127] In the embodiments of the present application, the processor may be a general-purpose processor, a digital signal processor, an application-specific integrated circuit, a field programmable gate array or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, etc., and may implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of the present application. The general-purpose processor may be a microprocessor or any conventional processor, etc. The steps of the method disclosed in the embodiments of the present application may be directly embodied as being executed by a hardware processor, or may be executed by a combination of hardware and software modules in the processor, etc.

[0128] In the embodiment of the present application, the memory may include, but is not limited to, non-volatile memory such as a hard disk drive (HDD) or a solid-state drive (SSD), random access memory (RAM), erasable programmable read-only memory (EPROM), read-only memory (ROM) or portable read-only memory (CD-ROM), etc. The memory is any storage medium that can be used to carry or store program code in the form of instructions or data structures and can be read and / or written by a computer (such as the communication device shown in the present application), but is not limited to this.

When data needs to be sent wirelessly, the processor 1702 performs baseband processing on the data to be sent, and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then sends the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 1702. The processor 1702 converts the baseband signal into data and processes the data.
