Detailed Description
In order that the above objects, features and advantages of the present application may be more clearly understood, a further description of the aspects of the present application will be provided below. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the application.
Fig. 1 shows a schematic diagram of a system architecture of an exemplary application environment in which the carrier routing method of the embodiments of the present application may be applied.
As shown in fig. 1, the system architecture 100 may include a BBU (Building Base band Unite, indoor baseband processing unit) 101, a network 102, and a forwarding system 103. The network 102 is used as a medium to provide a communication link between the indoor baseband processing unit 101 and the forwarding system 103. Network 102 may include various connection types such as wired, wireless communication links, or fiber optic cables, among others.
In the existing carrier routing technology between the base station and the forwarding system, carrier routing configuration modules with different pre-configured carrier bandwidths are adopted in the existing multi-system multi-carrier coexistence situation, and when carrier routing is carried out, corresponding carrier routing configuration modules are selected to carry out carrier routing configuration, but when bandwidths of two or more carriers are the same, especially when the carriers belong to different systems, the carrier routing conflict can be caused.
Based on this, the carrier routing method provided in the embodiments of the present application may be performed by the forwarding system 103, and accordingly, the carrier routing apparatus may be disposed in the forwarding system 103. For example, the indoor baseband processing unit 101 may send a carrier routing capability query request to the forwarding system 103 to query the carrier routing capability of the forwarding system 103. After receiving the carrier routing capability query request, the forwarding system 103 may return its own carrier routing capability information. In this way, the indoor baseband processing unit 101 may determine carrier routing configuration information according to the learned carrier routing capability of the forwarding system 103, and send the carrier routing configuration information to the forwarding system 103. The forwarding system 103 may perform routing according to the carrier routing configuration information after receiving the carrier to be routed.
Referring to fig. 2, fig. 2 is a flowchart of a carrier routing method in an embodiment of the present application, where the carrier routing method is applied to a forwarding system, and may include the following steps:
step S210, receiving a carrier routing capability query request sent by an indoor baseband processing unit, and returning carrier routing capability information aiming at the carrier routing capability query request, so that the indoor baseband processing unit determines carrier routing configuration information of a carrier to be routed according to the carrier to be routed and the carrier routing capability information; the carrier routing capability information is used for indicating the carrier routing capability of the forwarding system.
In this embodiment of the present application, the forwarding system refers to a portion where the remote unit is connected to the BBU, for example, may be an RRU (Remote Radio Unit ), or may be an AAU (Active Antenna Unit ), etc.
Specifically, the indoor baseband processing unit may send a carrier routing capability query request to the forwarding system to acquire the carrier routing capability of the forwarding system. After the forwarding system receives the carrier routing capability query request, the forwarding system can return the carrier routing capability information of the forwarding system. Optionally, the routing node of the forwarding system includes: the data processing channel, the radio frequency channel and the antenna port, and the carrier routing capability information may include: the number of antenna carriers supported by the forward transmission system, the number of data processing channels, the bandwidth supported by the data processing channels, the number of radio frequency channels, the antenna port of the radio frequency channel route, the frequency range supported by the radio frequency channels, the maximum output power of the radio frequency channels, the receiving and transmitting properties of the radio frequency channels and the like.
After receiving the carrier routing capability information sent by the forwarding system, the indoor baseband processing unit can determine carrier routing configuration information of the carrier to be routed according to the carrier to be routed and the carrier routing capability information. If the number of carriers to be routed is multiple, the corresponding carrier routing information can be configured for each carrier to be routed. The carrier routing configuration information of the carriers to be routed may include an association mapping of the carriers to be routed and routing nodes of the forwarding system, i.e. the carriers to be routed are routed through those routing nodes.
For example, if it is determined that the forwarding system supports the 2G carrier, the 3G carrier, and the 4G carrier, but does not support the 5G carrier based on the carrier routing capability information, the routing cases corresponding to the 2G carrier, the 3G carrier, and the 4G carrier may be determined, respectively, and the routing case of the 5G carrier may not be configured. The indoor baseband processing unit sends the carrier route configuration information to the forwarding system so that the forwarding system routes the received carrier according to the carrier route configuration information.
Step S220, receiving carrier route configuration information sent by the indoor baseband processing unit, and routing the carrier to be routed according to the carrier route configuration information.
In the embodiment of the present application, the carrier to be routed refers to a carrier received from the BBU, for example, may be a 2T (transmit) 2R (receive) carrier of 3G, a 2T2R carrier of 4G, a 1T1R carrier of 4G, and so on. According to different carriers to be routed, the carriers to be routed can be routed according to carrier routing configuration information.
According to the carrier routing method, the carrier routing capability information of the carrier routing capability information is returned by receiving the carrier routing capability query request sent by the indoor baseband processing unit, and the carrier routing capability information is used for indicating the carrier routing capability of the forwarding system. Thus, the indoor baseband processing unit can determine the carrier route configuration information within the capability range of the forwarding system according to the carrier route capability information. For example, different routes may be configured for carriers of different formats. The forwarding system receives the carrier route configuration information sent by the indoor baseband processing unit, and routes the carrier to be routed according to the carrier route configuration information. The method and the device can flexibly configure the carrier route based on the carrier route capability of the forwarding system, so that the flexibility of the carrier route can be improved.
Referring to fig. 3, fig. 3 is an interaction flow chart of a carrier routing method in an embodiment of the present application, which may include the following steps:
step S310, receiving a carrier wave routing capability query request sent by an indoor baseband processing unit through a general public wireless interface; or, receiving a carrier wave routing capability query request sent by the indoor baseband processing unit through the enhanced general public wireless interface.
In the embodiment of the application, communication between the BBU and the forwarding system is supported not only by CPRI (Common Public Radio Interface ), but also by eCPRI (enhanced CPRI). Through the communication mode, the indoor baseband processing unit can send the carrier wave routing capability query request to the forwarding system.
The eCPRI splits the processing procedure of the physical layer, the Low-PHY part is put into the forward transmission system for processing, the High-PHY part is put into the BBU for processing, and the splitting processing can reduce the communication data volume between the BBU and the forward transmission system. The BBU and the forward system correspond to AxC (antenna carrier) when CPRI communication is adopted, and correspond to eAxC (enhanced antenna carrier) when eCPRI communication is adopted.
Referring to fig. 4, fig. 4 is a schematic diagram of a routing node in a forwarding system according to an embodiment of the present application, it can be seen that the routing node of the forwarding system includes: the device comprises a data processing channel, a radio frequency channel and an antenna port. The BBU and the forwarding system adopt the Option7 interface of 3GPP R15.801, the forwarding system corresponds to the LowPHY processing channel, and the forwarding system adopts the Option8 interface, corresponds to the IQ processing channel. The carrier wave sent by the BBU can be routed according to the sequence of antenna carrier wave/enhanced antenna carrier wave- > LowPHY/IQ processing channel- > radio frequency channel- > antenna port.
Step S320, returning carrier routing capability information for the carrier routing capability query request, so that the indoor baseband processing unit determines carrier routing configuration information according to the carrier routing capability information; the carrier routing capability information is used for indicating the carrier routing capability of the forwarding system.
As previously indicated, the routing node of the forwarding system comprises: the carrier routing capability of the forwarding system, that is, the carrier routing capability of the data processing channel, the radio frequency channel and the antenna port, and the carrier routing capability information includes, but is not limited to: which AxC/eAxC are supported; the number of LowPHY/IQ processing channels, the bandwidth supported by each LowPHY/IQ processing channel, the number of radio frequency channels, the antenna port to which each radio frequency channel is routed, the frequency range supported by each radio frequency channel, the maximum output power of each radio frequency channel, the transmit-receive properties of each radio frequency channel, and so on.
Based on the carrier routing capability information, carrier routing configuration information can be determined. The carrier routing configuration information may include one or more of the following: the method comprises the steps of routing configuration information between an antenna carrier and a data processing channel, routing configuration information between the data processing channel and a radio frequency channel, and mapping relation between carrier numbers of the antenna carrier supported by a forwarding system and the data processing channel; wherein a single antenna carrier corresponds to one or more data processing channels and a single or more data processing channels corresponds to one radio frequency channel.
In the embodiment of the present application, a corresponding number may also be set for an antenna carrier, and a mapping relationship between the carrier number and the data processing channel may be set. Since the routes of the radio frequency channels and the antenna ports are generally fixed by hardware, the carrier route configuration information may not include the mapping relationship between the radio frequency channels and the antenna ports.
Step S330, receiving the carrier routing configuration information sent by the indoor baseband processing unit.
Step S340, returns response information for the carrier route configuration information.
It should be noted that, after the forwarding system receives the carrier route configuration information, if it is confirmed that the carrier route configuration information is correct, the forwarding system may reply to the BBU with response information, so as to inform the BBU that the forwarding system may route the carrier according to the carrier route configuration information.
Step S350, according to the carrier route configuration information, the carrier to be routed is routed.
In this embodiment of the present application, carriers to be routed include: one or more standard carriers, each standard carrier comprising one carrier or more carriers; one carrier of one system may adopt an existing routing manner, or may also adopt a routing manner of the present application, which is not described in detail herein, and the present application mainly describes carriers of two or more systems. For example, carriers to be routed may include: a 2T2R carrier of 4G and a 2T2R carrier of 5G; alternatively, the carriers to be routed include: a 1T1R carrier for 4G and a 2T2R carrier for 4G; alternatively, the carriers to be routed include: a 2T2R carrier of 3G, a 1T1R carrier of 4G, a 2T2R carrier of 5G, and the like.
The carrier routing capability information of the forwarding system is assumed to include: the number of antenna carriers supported by the forward transmission system is 4, the number of supported data processing channels is 4, the bandwidths supported by the first data processing channel are 80M and 100M, the bandwidths supported by the second data processing channel are 80M and 100M, the bandwidths supported by the third data processing channel are 5M, 10M, 15M and 20M, and the bandwidths supported by the fourth data processing channel are 5M, 10M, 15M and 20M. The number of the radio frequency channels is 4, the number of the antenna ports of the radio frequency channel route is 4, and the frequency range supported by the four radio frequency channels is 2515 MHz-2675 MHz. The maximum output power of the first radio frequency channel is 100dBm, the maximum output power of the second radio frequency channel is 100dBm, the maximum output power of the third radio frequency channel is 50dBm, and the maximum output power of the fourth radio frequency channel is 50dBm. The receiving and transmitting properties of the four radio frequency channels are all supporting receiving and transmitting.
Based on the carrier routing capability information, it may be determined that the first data processing channel and the second data processing channel of the forwarding system support a 5G carrier, and the third data processing channel and the fourth data processing channel support a 4G carrier. Then, if a 5G to-be-routed carrier is received, the to-be-routed carrier may be routed to the first data processing channel and/or the second data processing channel. If a 4G to-be-routed carrier is received, the to-be-routed carrier may be routed to the third data processing channel and/or the fourth data processing channel.
Referring to fig. 5, fig. 5 is a carrier routing example diagram of an eCPRI-based Option7 in an embodiment of the present application, where the eCPRI-based Option7 corresponds to a LowPHY processing channel. The routing is performed according to the carrier routing configuration information, which is specifically as follows:
the carrier to be routed C1 is a 5G 2T2R carrier and C2 is a 4G 2T2R carrier. Carrier numbers set for carrier C1 and carrier C2 are: eAxC1, eAxC2, eAxC3 and eAxC4, wherein the 1 st TR channel route of the C1 carrier is 'eAxC 1- > LowPHY1 processing channel- > radio frequency channel 1- > antenna port 1'; the 2 nd TR channel route of the C1 carrier is "eAxC2- > LowPHY1 processing channel- > radio frequency channel 1- > antenna port 1". The 1 st TR channel route of the C2 carrier is 'eAxC 3- > LowPHY3 processing channel- > radio frequency channel 3- > antenna port 3'; the 2 nd TR channel route of the C2 carrier is "eAxC4- > LowPHY4 processing channel- > radio frequency channel 4- > antenna port 4".

The carrier to be routed C1 is a 5G 2T2R carrier and C2 is a 5G 2T2R carrier. Carrier numbers set for carrier C1 and carrier C2 are: the 1 st TR channel route of the C1 carrier is 'eAxC 1- > IQ1 processing channel- > radio frequency channel 1- > antenna port 1' according to the pre-received carrier route configuration information by eAxC1, eAxC2, eAxC3 and eAxC 4; the 2 nd TR channel route of the C1 carrier is "eAxC2- > IQ2 processing channel- > radio frequency channel 1- > antenna port 1". The 1 st TR channel route of the C2 carrier is 'eAxC 3- > IQ3 processing channel- > radio frequency channel 3- > antenna port 3'; the 2 nd TR channel route of the C2 carrier is "eAxC4- > IQ4 processing channel- > radio frequency channel 4- > antenna port 4".

Carrier numbers set for carrier C1 and carrier C2 are: axC1, axC2 and AxC3, according to the pre-received carrier route configuration information, the route of the C1 carrier is 'AxC 1- > IQ1 processing channel- > radio frequency channel 1- > antenna port 1' and 'AxC 1- > IQ2 processing channel- > radio frequency channel 2- > antenna port 2'. The 1 st TR channel route of the C2 carrier is 'AxC 2- > IQ3 processing channel- > radio frequency channel 1- > antenna port 1'; the 2 nd TR channel route of the C2 carrier is "AxC3- > IQ4 processing channel- > radio frequency channel 2- > antenna port 2".
As can be seen from fig. 7, the relationship between eAxC and LowPHY/IQ processing channels may be one-to-many, and the relationship between LowPHY/IQ processing channels and radio frequency channels may be many-to-one.
The carrier routing method of the embodiment of the application can receive the carrier routing capability query request sent by the BBU and return the carrier routing capability information of the BBU. The BBU can determine carrier route configuration information according to the carrier route capability information and send the carrier route configuration information to the forwarding system, and the forwarding system can route the carrier to be routed according to the carrier route configuration information.
