Detailed Description
In order that the above-mentioned objects, features and advantages of the present application may be more clearly understood, the solution of the present application will be further described below. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
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 in other ways than those described herein; it is to be understood that the embodiments described in this specification are only some embodiments of the present application and not all embodiments.
Fig. 1 is a schematic diagram illustrating a system architecture of an exemplary application environment to which the carrier routing method according to the embodiment of the present application can be applied.
As shown in fig. 1, the system architecture 100 may include a BBU (Building Base band unit) 101, a network 102, and a fronthaul system 103. The network 102 is used to provide a medium for a communication link between the indoor baseband processing unit 101 and the fronthaul system 103. Network 102 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.
In the existing carrier routing technology between a base station and a fronthaul system, in the face of the existing coexistence of multiple systems and multiple carriers, carrier routing configuration modules with different carrier bandwidths are configured in advance, and during carrier routing, a corresponding carrier routing configuration module is selected to perform carrier routing configuration.
Based on this, the carrier routing method provided in the embodiment of the present application may be executed 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 fronthaul system 103 to query the fronthaul system 103 for the carrier routing capability. 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 known carrier routing capability of the fronthaul system 103, and send the carrier routing configuration information to the fronthaul system 103. After receiving the carrier to be routed, the forwarding system 103 may perform routing according to the carrier routing configuration information.
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 the 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 the embodiment of the present application, the forwarding system refers to a portion where a Remote Unit is connected to the BBU, and may be, for example, an RRU (Remote Radio Unit), an AAU (Active Antenna Unit), or the like.
Specifically, the indoor baseband processing unit may send a carrier routing capability query request to the forwarding system in order to obtain the carrier routing capability of the forwarding system. After receiving the carrier routing capability query request, the forwarding system can return the carrier routing capability information of itself. Optionally, the routing node of the forwarding system includes: 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 ports 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 transceiving attributes of the radio frequency channels and the like.
After receiving the carrier routing capability information sent by the fronthaul system, the indoor baseband processing unit may 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 the carriers to be routed is multiple, the carrier routing information corresponding to each carrier to be routed can be configured. The carrier routing configuration information of the carrier to be routed may include an association mapping between the carrier to be routed and the routing nodes of the forwarding system, i.e., the carrier to be routed is 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 statuses corresponding to the 2G carrier, the 3G carrier, and the 4G carrier may be determined respectively, and the routing status of the 5G carrier cannot be configured. And 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 the carrier routing configuration information sent by the indoor baseband processing unit, and routing the carrier to be routed according to the carrier routing configuration information.
In the embodiment of the present application, the carrier to be routed refers to a carrier received from the BBU, and may be, for example, a 2T (transmit) 2R (receive) carrier of 3G, a 2T2R carrier of 4G, a 1T1R carrier of 4G, or the like. According to different carriers to be routed, routing can be performed on the carriers to be routed according to the carrier routing configuration information.
The carrier routing method of the embodiment of the application returns the carrier routing capability information of the carrier routing method 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. In this way, the indoor baseband processing unit may determine carrier routing configuration information within the capability range of the forwarding system according to the carrier routing capability information. For example, different routes may be configured for carriers of different systems. The forwarding system receives the carrier routing configuration information sent by the indoor baseband processing unit, and can route the carrier to be routed according to the carrier routing configuration information. The method and the device can flexibly configure the carrier route based on the carrier route capability of the forward transmission system, so that the flexibility of the carrier route can be improved.
Referring to fig. 3, fig. 3 is an interactive flowchart of a carrier routing method in an embodiment of the present application, and the method may include the following steps:
step S310, receiving a carrier routing capability query request sent by an indoor baseband processing unit through a common public wireless interface; or, receiving a carrier routing capability query request sent by the indoor baseband processing unit through the enhanced universal public wireless interface.
In the embodiment of the present application, the BBU and the fronthaul system support not only Common Public Radio Interface (CPRI) communication but also enhanced CPRI (enhanced CPRI) communication. Through the communication mode, the indoor baseband processing unit can send the carrier routing capability query request to the forwarding system.
The eCPRI splits the processing process of the physical layer, the Low-PHY part is put into a fronthaul system for processing, and the High-PHY part is put into a BBU for processing. The BBU and the fronthaul 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 in an embodiment of the present application, and it can be seen that the routing node of the forwarding system includes: data processing channel, radio frequency channel and antenna port. The BBU and the forward transmission system adopt an Option7 interface of 3GPP R1538.801, the forward transmission system corresponds to a LowPHY processing channel, and adopt an Option8 interface, the forward transmission system corresponds to an IQ processing channel. The carriers transmitted by the BBU may be routed in the order of antenna carrier/enhanced antenna carrier- > LowPHY/IQ processing path- > radio frequency path- > antenna port.
Step S320, returning the carrier routing capability information aiming at the carrier routing capability query request, so that the indoor baseband processing unit determines the 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 indicated previously, the routing node of the forwarding system includes: data processing channel, radio frequency channel and antenna port, carrier routing capability of the forwarding system, that is, carrier routing capability of the data processing channel, radio frequency channel and 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 lanes, the bandwidth supported by each LowPHY/IQ processing lane, the number of radio frequency lanes, the antenna port routed by each radio frequency lane, the frequency band range supported by each radio frequency lane, the maximum output power of each radio frequency lane, the transceiving property of each radio frequency lane, and the like.
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: routing configuration information between the antenna carrier and the data processing channel, routing configuration information between the data processing channel and the radio frequency channel, and a mapping relation between the carrier number of the antenna carrier supported by the forwarding system and the data processing channel; the single antenna carrier corresponds to one or more data processing channels, and the single or more data processing channels correspond to one radio frequency channel.
In the embodiment of the application, a corresponding number can be set for the antenna carrier, and a mapping relation between the carrier number and the data processing channel can be set. Since the routes of the rf channel and the antenna port are generally fixed by hardware, the carrier route configuration information may not include the mapping relationship between the rf channel and the antenna port.
Step S330, receiving the carrier routing configuration information sent by the indoor baseband processing unit.
Step S340 returns response information to the carrier route configuration information.
It should be noted that, after the forwarding system receives the carrier route configuration information, if it is determined that the carrier route configuration information is correct, a response message may be replied to the BBU to notify the BBU forwarding system that the carrier may be routed according to the carrier route configuration information.
And step S350, routing the carrier to be routed according to the carrier routing configuration information.
In the embodiment of the present application, the carrier to be routed includes: the carrier waves of one or more systems comprise one carrier wave or a plurality of carrier waves; one carrier of one system can adopt the existing routing mode and can also adopt the routing mode of the application, detailed description is omitted, and the application mainly describes the carriers of two or more systems. For example, the carriers to be routed may include: 2T2R carrier of 4G and 2T2R carrier of 5G; or, the carrier to be routed includes: 1T1R carrier of 4G and 2T2R carrier of 4G; or, the carrier to be routed includes: 2T2R carriers of 3G, 1T1R carriers of 4G, and 2T2R carriers of 5G, etc.
The carrier routing capability information of the forwarding system is assumed to include: the number of antenna carriers supported by the fronthaul system is 4, the number of supported data processing channels is 4, the bandwidth supported by the first data processing channel is 80M and 100M, the bandwidth supported by the second data processing channel is 80M and 100M, the bandwidth supported by the third data processing channel is 5M, 10M, 15M and 20M, and the bandwidth supported by the fourth data processing channel is 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 50 dBm. The transceiving properties of the four radio frequency channels are all supporting receiving and transmitting.
Based on the carrier routing capability information, it can be determined that the first data processing channel and the second data processing channel of the forwarding system support 5G carriers, and the third data processing channel and the fourth data processing channel support 4G carriers. Then, if the carrier to be routed of 5G is received, the carrier to be routed may be routed to the first data processing channel and/or the second data processing channel. If the 4G carrier to be routed is received, the carrier to be routed can be routed to the third data processing channel and/or the fourth data processing channel.
Referring to fig. 5, fig. 5 is a diagram illustrating a carrier routing example of Option7 based on the eccri in the embodiment of the present application, where Option7 based on the eccri corresponds to a LowPHY processing channel. Routing according to the carrier routing configuration information specifically includes:
the carrier C1 to be routed is a 2T2R carrier of 5G, and C2 is a 2T2R carrier of 4G. The carrier numbers set for carrier C1 and carrier C2 are: eAxC1, eAxC2, eAxC3 and eAxC4, according to the carrier route configuration information, 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 "eAxC 2- > LowPHY1 processing channel- > radio channel 1- > antenna port 1". The route of the 1 st TR channel 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 "eAxC 4- > LowPHY4 processing channel- > radio frequency channel 4- > antenna port 4".

The carrier C1 to be routed is a 2T2R carrier of 5G, and C2 is a 2T2R carrier of 5G. The carrier numbers set for carrier C1 and carrier C2 are: eAxC1, eAxC2, eAxC3 and eAxC4, according to the pre-received carrier route configuration information, the 1 st TR channel route of the C1 carrier is 'eAxC 1- > IQ1 processing channel- > radio frequency channel 1- > antenna port 1'; the 2 nd TR channel route of the C1 carrier is "eAxC 2- > IQ2 processing channel- > radio frequency channel 1- > antenna port 1". The route of the 1 st TR channel 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 "eAxC 4- > IQ4 processing channel- > radio frequency channel 4- > antenna port 4".
As can be seen from fig. 5 and fig. 6, the eAxC and the LowPHY/IQ processing path, and the LowPHY/IQ processing path and the rf path may be in a one-to-one relationship.
Referring to fig. 7, fig. 7 is a carrier routing example diagram of Option8 based on the eccri in the embodiment of the present application, where Option8 based on the eccri corresponds to an IQ processing channel. The carrier C1 to be routed is a 1T1R carrier of 4G, and C2 is a 2T2R carrier of 4G. The carrier numbers set for carrier C1 and carrier C2 are: AxC1, AxC2 and AxC3, according to the carrier route configuration information received in advance, 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 route of the 1 st TR channel 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 "AxC 3- > IQ4 processing channel- > radio frequency channel 2- > antenna port 2".
As can be seen from fig. 7, the eAxC and the LowPHY/IQ processing channel may have a one-to-many relationship, and the LowPHY/IQ processing channel and the rf channel may have a many-to-one relationship.
