It should be understood that, in the embodiment of the present invention, the hardware structure of the DU is similar to the hardware structure of the FHM device shown in fig. 2, and the description of the hardware structure of the DU may refer to the description of the hardware structure of the FHM device, which is not described in detail herein.
The method and the device for transmitting the base station forward data stream provided by the embodiment of the invention are applied to a scene that a DU issues the data stream to a RU. When a DU needs to send a data stream to a specific RU, the data stream may be sent to the RU via a specific device (i.e., at least one FHM device) and a specific port in the device based on the method for transmitting the base station forward data stream provided by the embodiment of the present invention.
In conjunction with the communication system shown in fig. 1, the following fully describes the transmission method of the base station forward data stream from the perspective of interaction among the devices in the communication system, so as to describe a process of acquiring a global port identifier by an FHM device and a process of sending a data stream from a specific port by an FHM device.
As shown in fig. 3, a transmission method of a base station forward data stream according to an embodiment of the present invention may include S101 to S105.
S101, the FHM equipment sends topology information and port information of the FHM equipment to the DU.
It should be understood that during the startup process of the DU and RU, processes such as capability discovery, information retrieval, and topology discovery need to be performed. It can be understood that the capability discovery is that the RU needs to exchange its own capability (or characteristics) with the capability of the DU; information retrieval, namely, the DU needs to retrieve certain specific attributes of the RU; topology discovery is the need for the DU to obtain topology information of other devices (e.g., FHM devices or switch devices) between it and the RU devices.
Specifically, each FHM device (e.g., FHM device) may send the communication relationship between the FHM device and other devices, and the ports through which the FHM device communicates with other devices to the DU, so that the DU may allocate a global port identifier to the FHM device, and further, when the DU needs to send a data stream, the FHM device may send the data stream to a specific RU through a specific path.
It should be noted that, before S101, the DU may send an information acquisition request to multiple FHM devices (including FHM devices), that is, request to acquire topology information and port information of the multiple FHM devices, and thus, after the multiple FHM devices receive the information acquisition request, the topology information and port information may be sent to the DU accordingly.
S102, the DU acquires topology information and port information of a plurality of FHM devices.
Exemplarily, with reference to fig. 1, the topology information and the port information of the FHM device 104 acquired by the DU 101 specifically include: FHM device 104 connects to FHM device 102 through "port 1" in the FHM device 104, to RU 107 through "port 2" in the FHM device 104, and to RU 108 through "port 3" in the FHM device 104.
S103, the DU determines the global port identification corresponding to each FHM device based on the topology information and the port information of the FHM devices.
Wherein, a port in an FHM device corresponds to a global port id, and the global port id includes a hierarchy id corresponding to the FHM device and a device id corresponding to the FHM device.
It should be understood that determining, by the DU, a global port identifier corresponding to one FHM device is determining a global port identifier of each of a plurality of ports in the FHM device, where one global port identifier is used to identify uniqueness of one port, that is, the DU may allocate one global port identifier to a certain port in the FHM device, or determine which port in which FHM device it belongs to according to a certain global port identifier.
In an implementation manner of the embodiment of the present invention, the DU may modify the YANG model based on topology information and port information of multiple FHM devices, specifically, construct a portal-global-id (i.e., global port identifier) including a new parameter of the YANG model, and configure the portal-global-id to the FHM device. The modified YANG model is specified below:
in an implementation manner of the embodiment of the present invention, the step S103 specifically includes a step a to a step C.
Step A, DU determines a tier identification and a device identification for each of the plurality of FHM devices based on the topology information of the plurality of FHM devices.
Optionally, the DU may determine a hierarchy of a certain FHM device in multiple FHM devices as a corresponding hierarchy id of the FHM device, and may determine an nth position in the hierarchy as a device id thereof, where n ≧ 1.
Exemplarily, in conjunction with fig. 1, the DU may determine that the FHM device 104 corresponds to a hierarchy identifier of 2, i.e. the FHM device 104 is in a second tier among the plurality of FHM devices (the FHM device 104 is the second tier FHM device described above). And the DU may also determine that the device identity corresponding to the FHM device 104 is 1, i.e. the 1 st position of the FHM device 102 in the second layer, which may be understood as that the FHM device 104 is the 1 st FHM device in the FHM devices in the second layer.
Step B, DU determines a port identification for each of a plurality of ports in the FHM device based on the port information for the FHM device.
Wherein the FHM device is one of the plurality of FHM devices.
Alternatively, the DU may determine the port identification of the mth port in the FHM device as m, where m ≧ 1.
In connection with the example in S102, the DU may determine that the port identities of the 1 st port, the 2 nd port, and the 3 rd port in the FHM device 104 are 1, 2, and 3, respectively.
Step C, DU generates a global port id for each of the plurality of ports in the FHM device based on the hierarchy information corresponding to the FHM device, the device information corresponding to the FHM device, and the port id for each of the plurality of ports in the FHM device.
It should be understood that the global port id of each port in the DU generation FHM device is the global port id corresponding to the FHM device.
Exemplarily, in combination with the example in the above step a and step B, the DU may determine 3 global port ids corresponding to the FHM device 104, which are 2-1-1, 2-1-2, and 2-1-3, respectively, and are a global port id of a 1 st port, a global port id of a 2 nd port, and a global port id of a 3 rd port in the FHM device 104.
To this end, the DU may determine a global port id corresponding to each FHM device in the multiple FHM devices.
In an implementation manner of the embodiment of the present invention, after the step S103, the method for transmitting the forward data stream by the base station according to the embodiment of the present invention further includes a step D.
Step D, DU determines the data stream transmission path corresponding to the target RU.
The data transmission path corresponding to the target RU includes at least one global port identifier, and the target RU is one of the plurality of RUs.
It is understood that the target RU may receive the data stream transmitted by the DU step by step through the at least one global port identity.
In connection with the example in step C, assuming that the target RU is RU 107, the data transmission path corresponding to the RU 107 may include at least the global port id (i.e. 1-1-2) of the 2 nd port (the port located below the FHM device 102) in the FHM device 102 and the global port id (i.e. 2-1-2) of the 2 nd port in the FHM device 104, i.e. the DU may determine that the data stream sent by the DU may reach the RU 107 via the 2 nd port in the FHM device 102 and the 2 nd port in the FHM device 104, respectively.
Optionally, after the DU determines the data stream transmission path corresponding to the target RU, the DU may store the data stream transmission path corresponding to the target RU in the local database.
S104, DU sends the global port identification corresponding to the FHM devices respectively.
In connection with the above description of the embodiments, it should be understood that the global port identifier corresponding to one FHM device is an identifier of a global port of each of a plurality of ports in the FHM device, that is, when the FHM device includes a plurality of ports, the number of global port identifiers corresponding to the FHM device is multiple.
S105, the FHM equipment receives a plurality of global port identifications sent by the DU.
Wherein, a global port identifier corresponds to a port in the FHM device, and the global port identifier includes a hierarchy identifier (hereinafter referred to as a first hierarchy identifier) corresponding to the FHM device and a device identifier (hereinafter referred to as a first device identifier) corresponding to the FHM device.
It should be understood that the global port identifiers in S105 are the global port identifiers corresponding to the FHM device, specifically, the global port identifiers of the ports in the FHM device.
Thus, the plurality of FHM devices (including the FHM device) may receive (or obtain) the global port identifier corresponding to each of the plurality of FHM devices.
In the method for transmitting the base station forward data stream provided by the embodiment of the present invention, a plurality of FHM devices (including FHM devices) may send respective topology information and port information to a DU; the DU may determine global port information corresponding to each of the plurality of FHM devices (i.e., global port information of each of a plurality of ports included in each of the plurality of FHM devices) based on the topology information and the port information of the plurality of FHM devices, and send the global port information corresponding to each of the plurality of FHM devices to the plurality of FHM devices, so that the plurality of FHM devices, for example, FHM devices, may receive a plurality of global port identities. In the embodiment of the present invention, a DU may determine and allocate (i.e., send) a plurality of global port identifiers to a plurality of FHM devices based on topology information and port information of the FHM devices, so that the FHM devices may receive the global port identifiers, and when a certain FHM device receives a data stream sent by the DU, it may be determined whether the FHM device is an FHM device that needs to receive and send the data stream and which port sends the data stream based on the global port identifiers, which may reasonably and accurately determine an intermediate device that sends the data stream, thereby improving data transmission efficiency.
As shown in fig. 4, the transmission method for the base station fronthaul data stream according to the embodiment of the present invention may further include S201-S205.
S201, DU sends data flow to FHM equipment.
Specifically, the data stream includes a plurality of pieces of routing information, where one piece of routing information includes a hierarchy identifier, a device identifier, and a port bit mask.
It should be understood that the data flow in the embodiment of the present invention may be a control plane message or a user plane message, and in the following embodiment, a data flow sent by a DU is taken as an example for description, and it should be understood that, when the data flow sent by the DU is a user plane message, the transmission (or forwarding) of the user plane message may also be completed based on the transmission method for a base station forward data flow provided by the present invention.
The control plane message in the embodiment of the present invention may adopt an enhanced common public radio interface (eCPRI) protocol, and is composed of an eCPRI message header, an extended message body, a control plane message header, and a control plane message body, and the entire message may be encapsulated into an ethernet frame as payload.
Exemplarily, as shown in fig. 5, an example of a control plane message provided by the embodiment of the present invention is provided.
Specifically, the extension message header includes an ef field, an extType field, and an extLen field. The ef field may be understood as an extension identifier, for example, when the value of the ef field is 0, it indicates that there is no extension message body (or the extension message body is empty), and when the value of the ef field is 1, it indicates that there is an extension message body; the extType field is used to represent the type of the extended message body, for example, when the value of the extType field is 0, the extType field may be represented as a reserved field, and is not processed for the time being, and when the value of the extType field is 1, the type of the extended message body is represented as routing information, that is, the extended message body includes at least one piece of routing information; the extLen field indicates the length of the extended message body and may have a unit of Byte.
As shown in fig. 5, the case where the value of the ef field is 1 and the value of the extType field is also 1 is described, that is, the control plane message shown in fig. 5 is the control plane message whose type of the extended message body is the routing information. The extended message body includes at least one piece of routing information, and one piece of routing information includes one level (i.e., a hierarchical identifier), one number (i.e., a device identifier), and one port bit mask (it should be understood that one port bit mask shown in fig. 5 includes 2 high-order bits and 8 low-order bits by using 2 portbitmasks, that is, one port bit mask includes 2 high-order bits and 8 low-order bits). Specifically, the level is used to indicate a level identifier corresponding to a certain FHM device, the number is used to indicate a device identifier corresponding to the FHM device, and the port bit mask is used to identify at least one port corresponding to the FHM device, it should be understood that the FHM device is a device that needs to be routed (or routed) when the control plane message is transmitted, or specifically, it may be understood that the FHM device may reach a corresponding RU through routing information included in the control plane message.
The user plane message in the embodiment of the present invention may also adopt an eCPRI protocol, and specifically, the user plane message is composed of an eCPRI message header, an extended message body, a control plane message header, and a control plane message body, and the entire message may be encapsulated in an ethernet frame as payload.
Illustratively, as shown in fig. 6, an example of a user plane message provided by the embodiment of the present invention is provided.
It should be noted that, in the embodiment of the present invention, the explanation of the user plane message is the same as or similar to the description of the control plane message, and is not described herein again.
In conjunction with the description of the above embodiment, it should be understood that, after determining the data streaming path corresponding to the target RU, the DU may store the data streaming path corresponding to the target RU in a local database, and in particular, the data streaming path may be used to characterize through which port (i.e., at least one global port identifier included in the data streaming path) in which FHM device the data stream sent by the DU to the target RU needs to reach the target RU. Thus, in the case that the DU needs to send a certain data flow to the target RU, the DU may configure relevant routing information based on the data transmission path, and then add the routing information to the data flow.
S202, the FHM equipment receives the data stream sent by the DU.
Specifically, the data stream includes a plurality of pieces of routing information, where one piece of routing information includes a hierarchy identifier, a device identifier, and a port bit mask.
S203, the FHM device determines whether the first tier identification is the same as the target tier identification, and whether the first device identification is the same as the target device identification.
The first hierarchical identifier is a hierarchical identifier corresponding to the FHM device, the target hierarchical identifier is a hierarchical identifier included in target routing information, the target routing information is one of the plurality of pieces of routing information, the first device identifier is a device identifier corresponding to the FHM device, and the target routing device identifier is a device identifier included in the target routing information.
In connection with the above description of the embodiments, it should be understood that the FHM device may receive multiple global identities sent by the DU, and thus, the FHM device may determine its corresponding hierarchical identity (i.e. the first hierarchical identity) and its corresponding device identity (i.e. the first device identity). Specifically, the hierarchical identifiers included in the global identifiers are the first hierarchical identifiers, and the device identifiers included in the global identifiers are the first device identifiers.
It is understood that when the first tier identification is the same as the target tier identification and the first device identification is the same as the target device identification, the FHM device is identified as the FHM device that needs to send the data stream, or it is understood that the data stream sent by the DU needs to be sent to the next FHM device or RU through the FHM device. Otherwise, that is, when the first tier id is not the same as the target tier id or the first device id is not the same as the target device id, it indicates that the data stream sent by the DU does not need to be sent to the FHM device, or the FHM device does not need to send the data stream to other devices.
S204, under the condition that the first level identification is the same as the target level identification and the first device identification is the same as the target device identification, the FHM device determines at least one target port based on the target port bit mask.
Wherein the destination port bitmask is a port bitmask included in the destination routing information.
In connection with the above description of the embodiment, it should be understood that, when the first tier id is the same as the target tier id and the first device id is the same as the target device id, it indicates that the data stream sent by the DU needs to be sent to the next tier FHM device or RU through the FHM device, and then the FHM device may determine at least one target port based on the target port bit mask included in the target routing information, where the at least one target port is the port for sending the data stream, and specifically, one target port bit mask may correspond to at least one target port.
In one implementation of the embodiment of the present invention, a port bitmask may be formed in q numbers (for example, q may be 10), each of the q numbers may be 0 or 1, when the p (p ≧ 1) number is 1, it indicates that a data stream needs to be transmitted through the p-th port in the FHM device, and when the p-th number is 0, it indicates that the p-th port in the FHM device does not need to transmit the data stream.
For example, assuming that the port bitmask (i.e., the target port bitmask) included in the data stream is 0111100000, the FHM device may determine that the at least one target port is the 2 nd, 3 rd, 4 th, and 5 th ports of the FHM device.
Optionally, the transmission method for the base station forward data stream provided in the embodiment of the present invention may further include step E.
And E, under the condition that the first level identification is not the same as the target level identification or the first equipment identification is not the same as the target equipment identification, the FHM equipment discards the data stream.
In connection with the above description of the embodiments, it should be understood that in the case that the first tier identification is not the same as the target tier identification, or the first device identification is not the same as the target device identification, the FHM device does not need to send the data stream to other devices, and thus the FHM device can discard the data stream.
S205, the FHM device sends a data stream from at least one target port.
Illustratively, referring to fig. 1, assuming that the FHM device is the FHM device 102 and the at least one destination port includes the 2 nd port of the FHM device 102, the FHM device 102 determines to send the data stream from the 2 nd port to the FHM device 104. If the FHM device is an FHM device 104 and the at least one target port includes the 3 rd port of the FHM device 104, then the FHM device 104 determines to send the data stream from the 3 rd port to RU 108.
Exemplarily, in conjunction with fig. 1 and S104 described above, as shown in fig. 7, it is assumed that the global port identifications determined by the DU 101 and transmitted (or configured) for the FHM device 102 and the FHM device 104 are 1-1-1, 1-1-2, 2-1-1, 2-1-2, and 2-1-3, respectively, where 1-1-1 and 1-1-2 belong to the FHM device 102, and 2-1-1, 2-1-2, and 2-1-3 belong to the FHM device 104.
Further, assume that 2 pieces of routing information, such as routing information 1 and routing information 2, are included in the data flow sent by DU 101, the level id, the device id, and the port bit mask included in routing information 1 are 1, and 0100000000, respectively, and the level id, the device id, and the port bit mask included in routing information 2 are 2, 1, and 0010000000, respectively. FHM device 102 determines to send the data stream to FHM device 104 through the port identified by global port 1-1-2 and FHM device 104 determines to send the data stream to RU 108 through the port 2-1-3.
In the method for transmitting a base station forward data stream provided in the embodiment of the present invention, a DU sends a data stream to an FHM device, so that after the FHM device receives the data stream, it may be determined whether the first tier identification (i.e. the tier identification corresponding to the FHM device) is the same as the target tier identification (i.e. the tier identification included in the target routing information), and whether the first device identity (i.e. the device identity corresponding to the FHM device) is the same as the target device identity (i.e. the device identity included in the target routing information), further, in the case where the first hierarchical identifier is the same as the target hierarchical identifier, and the first device identifier is the same as the target device identifier, the FHM device determines at least one target port based on a target port bitmask (i.e., a port bitmask included in the target routing information) and transmits the data stream from the at least one target port. In the embodiment of the present invention, the FHM device may determine, according to the routing information included in the data stream, specifically, the hierarchical identifier and the device identifier included in the routing information, whether the FHM device is a device to be transmitted corresponding to the data stream, and may understand whether the received data stream needs to be transmitted (or sent) to another device, and in a case that the FHM device is determined to be the device to be transmitted corresponding to the data stream, the FHM device sends the data stream to another device (including a next-layer FHM device or RU) from at least one port in the FHM device, so that a transmission device for transmitting the data stream before a certain base station can be accurately and reasonably determined, and the transmission efficiency of the data can be improved.
