Description

Network configuration method, device and system

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a network configuration method, apparatus, and system.

Background

At present, the development and application of the fifth generation mobile communication (5th generation mobile networks, 5G) technology are actively developed, which not only provides high-speed service flow for mobile users, but also provides low-delay, large-connection, high-bandwidth and other performances for service applications in other different industries; in order to meet the diversified requirements of the 5G services, the network needs to be more flexible and high-powered, and for this reason, the third generation partnership project (3 GPP) standard organization defines a plurality of technologies to meet the requirements of the new era, including various technologies such as cloud-based modular deployment of a core network, a more flexible frame structure at a wireless side, subcarrier spacing, large-scale multiple antennas, and the like, and also provides a base station architecture based on central unit-distributed unit (CU-DU) separation as shown in fig. 1.

As the 5G access network requires that the protocol stack function can be migrated between the CU and the DU, after the CU-DU is separated, an F1 interface of a newly defined interface is introduced, and the transfer of the configuration function between the CU and the DU can be realized through an F1 interface; the existing DU configuration is implemented in two ways, one is that the CU network management system performs some basic configurations (such as cell ID) on the connected DUs through the F1 interface, the DU network management system performs specific function configuration (such as subcarrier spacing), and the other is that the CU network management system manages the DUs through the F1 interface and issues all configurations to the DUs through the F1 interface. For the first configuration mode, an operator needs to maintain two sets of network management systems configured by a CU and a DU, and the configuration mode is too complex; for the second configuration mode, since the network management system of the CU issues all configurations to the DUs through the F1 interface, the configurations of the DUs connected to the CU are completely the same, and the configuration cannot meet the requirements of all user terminal services in practical application, and lacks certain flexibility; meanwhile, since the network management system of the CU needs to manage all the configurations of the DU, the device coupling degree of the CU and the DU is high, so the configuration mode is limited to that the CU and the DU are devices of the same manufacturer, and when the CU and the DU are devices of different manufacturers, decoupling between the devices is not facilitated.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the present application, the meaning of "a plurality" means two or more unless otherwise specified.

In order to meet the diversified requirements of 5G services, the 3GPP standard organization proposes a base station architecture based on CU-DU separation as shown in fig. 1, in the base station architecture shown in fig. 1, two separate devices, CU and DU, implement all protocol functions of a baseband processing Unit (BBU) in a 4G base station as shown in fig. 2. The CU may be deployed at a higher location in a network architecture, such as a convergence room, and connected to a 5G Core network (5G Core) through an interface to process higher layer protocol functions such as a Radio Resource Control (RRC) protocol layer and a Packet Data Convergence Protocol (PDCP) layer in a non-real-time manner; the DU may be deployed in an access machine room, and process a bottom layer protocol function with high latency and calculation requirements, such as a real-time physical layer, a Media Access Control (MAC) layer, and a Radio Link Control (RLC) layer, where generally, several tens of DU devices are connected below one CU device, and may support data processing at hundreds of cell levels, as shown in fig. 1, where the DU is connected downward with an Active Antenna Unit (AAU) through an interface, where the AAU is composed of a Remote Radio Unit (RRU) and an antenna.

In the former 4G base station, the complete protocol stack is located in the same base station device (BBU), the intercommunication of messages and configuration is realized through an internal interface, and after the existing CU-DU is separated, in order to meet the requirement of a 5G access network, the function of the protocol stack can be migrated between the CU and the DU, so an F1 interface of a newly defined interface is introduced, and the coordination and interaction of the function configuration of the CU and the DU can be transmitted through an F1 interface.

The existing architecture with separated CU and DU can lead the management of wireless resources to be more centralized, in addition, because the CU only bears the non-real-time high-level functions, the difficulty of realizing virtualization is relatively low, and in the deployment of the CU-DU architecture, the CU can be deployed on general hardware (server) based on some virtualization technologies, thus leading the deployment position to be very flexible and meeting the differentiated service requirements; since the processing capability of the general-purpose hardware is limited, and the DU is a function of processing the underlying protocol with high requirements for delay and calculation, the DU still adopts a part of proprietary hardware to complete the function of the physical layer, for example, the DU can be completed by a Digital Signal Processor (DSP) or an Application Specific Integrated Circuit (ASIC).

Although a wireless networking mode based on a CU-DU architecture can bring many advantages, both existing configuration modes have some problems.

At present, the configuration of the DU is implemented in two ways, one of which is that a network management system of the CU performs some basic configurations on a connected DU through an F1 interface, for example, a carried cell ID, and a network management system carried by the DU side itself performs specific function configurations, for example, uplink-downlink timeslot matching, subcarrier spacing, multiple-input-multiple-output (MIMO) mode, etc., for this configuration, the related configuration and update of the DU also need to be reported to the CU at the same time, an operator needs to maintain two sets of network management systems configured by the CU and the DU, the configuration is too complex, and the cost is too high when a large number of DUs are deployed in the future, which is not beneficial to wide popularization; the second is that the network management system of the CU manages the DUs through the F1 interface and issues all the configurations to the DU through the F1 interface, and for the second configuration mode, the network management system of the CU issues the configurations of the related functions to the DU through the F1 interface, so the configurations of a plurality of DUs connected to the CU are completely the same, and the requirements of different types of user terminal services cannot be met in practical application, and certain flexibility is lacked; in addition, at this time, since the network management system of the CU needs to manage all configurations of the DU, the device coupling degree between the CU and the DU is high, and thus the second configuration mode is limited to that the CU and the DU are devices of the same manufacturer, and when the CU and the DU are devices of different manufacturers, decoupling between the devices is not facilitated.

In view of the above problems in the CU-DU configuration method in the prior art, an embodiment of the present application provides a network configuration method.

The network configuration method provided in the embodiment of the present application is applied to the system architecture shown in fig. 3, where the system architecture includes a CU, a DU, and a user terminal.

And the CU is used for sending a configuration instruction carrying the first configuration parameter to the DU connected with the CU.

And the CU is also used for acquiring the first operation parameter of the DU and/or the first service performance parameter of the user terminal connected with the DU when receiving the configuration completion message sent by the DU.

And the CU is also used for determining a second configuration parameter according to the first service performance parameter and/or the first operation parameter.

And the CU is also used for sending a first updating instruction carrying the second configuration parameters to the DU.

And the DU is used for receiving a configuration instruction which is sent by the CU connected with the DU and carries the first configuration parameter.

And the DU is also used for sending a configuration completion message to the CU after the network configuration of the DU is completed according to the first configuration parameter.

And the DU is also used for receiving a first updating instruction which is sent by the CU and carries second configuration parameters.

And the DU is also used for updating the network configuration of the DU according to the second configuration parameters.

The user terminal may be different types of terminals connected to the DU, such as a mobile phone, a tablet computer, a desktop computer, a laptop computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a Personal Digital Assistant (PDA), a wearable electronic device, and a virtual reality device.

Based on the above system architecture, as shown in fig. 4, an embodiment of the present application provides a network configuration method, which may include S101-S1010:

s101, the CU sends a configuration instruction carrying a first configuration parameter to a DU connected with the CU.

Specifically, step S101 is one of the specific implementations of S301 in fig. 11.

Since coordination and interaction of function configurations of the CU and the DU may be transferred through the F1 interface, the CU may send a configuration instruction carrying a first configuration parameter to the DU connected to the CU through the F1 interface, where the first configuration parameter at least includes: initial cell ID, uplink and downlink signal frequency, uplink and downlink ratio, subcarrier interval and MIMO mode.

Wherein the initial cell ID is an identity of the cell.

The uplink and downlink signal frequencies are carrier frequencies for transmitting or receiving signals, and the magnitude of the uplink and downlink signal frequencies is generally defined by an operator.

The uplink and downlink ratio is a resource ratio set for the size of the uplink traffic and the downlink traffic of the user terminal.

The subcarrier spacing refers to the spacing from the center frequency of one subcarrier to the center frequency of the next subcarrier, generally, a frequency band is divided into a plurality of subcarriers, each subcarrier occupies a segment of width, which is the subcarrier spacing, and the larger the subcarrier spacing is, the lower the time delay is, so that the time delay can be reduced by increasing the subcarrier spacing.

The MIMO mode is several different modes defined by the MIMO system according to parameters such as channel quality and the like and applicable to different types of application scenarios, including a single-wire working mode, open-loop spatial multiplexing, closed-loop spatial multiplexing and the like.

The configuration instruction is at least used for indicating the DU to carry out network configuration on the DU according to the first configuration parameter; of course, in practical applications, the first configuration parameter may also include other types of parameters for network configuration of the DU, and is not limited herein.

S102, the DU receives a configuration instruction which is sent by a CU connected with the DU and carries a first configuration parameter.

Specifically, step S102 is one of the specific implementations of S302 in fig. 11.

S103, the DU completes the network configuration of the DU according to the first configuration parameter.

When the DU receives the first configuration parameter sent by the CU, the network configuration itself may be completed according to the first configuration parameter, that is, the initial cell ID, the uplink and downlink signal frequency, the uplink and downlink ratio, the subcarrier interval, the MIMO mode, and the like are set.

S104, the DU sends a configuration completion message to the CU.

After the DU completes its configuration according to the first configuration parameter, it may send a configuration completion message to the CU, and at the same time, the ue may access the service normally, specifically, the DU may first send an access request to the ue (one of the specific implementations of S303 in fig. 11), and the ue sends an access response to the DU after accessing the service (one of the specific implementations of S304 in fig. 11).

The configuration completion message is at least used for indicating that the DU completes the network configuration according to the first configuration parameter.

S105, the CU receives the configuration completion message sent by the DU.

S106, the CU acquires a first operation parameter of the DU and/or a first service performance parameter of the user terminal connected with the DU.

After the CU receives the configuration completion message sent by the DU, the CU may obtain a first operating parameter of the DU, where the first operating parameter at least includes: uplink and downlink resource utilization rate, scheduling of an MAC layer and connection rate with a user terminal.

The uplink and downlink resource utilization rate refers to the utilization rate of uplink resources or downlink resources of a user terminal connected with the DU, which accounts for the proportion of the DU; the dispatching of the MAC layer refers to that the MAC layer accesses the resources distributed to the DU according to the type, the number and the like of the user terminal accessed by the DU; the connection rate with the ue indicates a ratio of the number of ues connected to the DU at a certain time and operating a service to the total number of ues actually managed by the DU, and when the connection rate with the ue at a certain time is 0, it indicates that no ue is operating a service at that time.

In addition, since the ue has normally accessed the service at this time, the CU may obtain a first service performance parameter of the ue connected to the DU, where the first service performance parameter at least includes: location, uplink and downlink throughput, bit error rate, channel model and moving speed.

The position refers to a position of the user terminal, the channel model represents a model for transmitting signals in a channel, and it should be noted that the MIMO mode applicable to the DU may be determined according to parameters such as the position and the channel model; the uplink throughput represents the rate of uploading data, and the downlink throughput represents the rate of downloading data; the bit error rate represents the error rate of the received data; the moving speed indicates a moving speed of the user terminal.

It should be noted that, since the CU handles the non-real-time higher layer function, the CU itself may obtain higher layer data such as the initial cell ID and the ID of the user terminal currently connected to the DU, but specifically what kind of resources are used by each user terminal and real-time lower layer data such as uplink and downlink throughput need to be reported to the CU through the DU, that is, the CU may obtain the first service performance parameter of the user terminal connected to the DU through the F1 interface.

Optionally, as shown in fig. 5, the specific step of the CU obtaining the first operation parameter of the DU and/or the first service performance parameter of the user terminal connected to the DU in step S106 specifically includes: S1061-S1062:

s1061, the CU sends the target request to the DU.

The target request is used for the CU to request the DU for first operation parameters and/or first service performance parameters of the user terminal connected to the DU.

Specifically, step S1061 is one of the specific implementations of S305 in fig. 11.

S1062, the CU receives the target response sent by the DU.

Specifically, step S1062 is one of the specific implementations of S306 in fig. 11.

It should be noted that, when the target request is used for the CU to request the first operation parameter of the DU from the DU, the CU receives the first operation parameter carried by the target response sent by the DU; when the target request is used for the CU to request the first service performance parameter of the user terminal connected with the DU from the DU, the CU receives the target response sent by the DU and carries the first service performance parameter of the user terminal connected with the DU.

And S107, the CU determines a second configuration parameter according to the first service performance parameter and/or the first operation parameter.

The second configuration parameter is an optimization parameter for the current operation state of the DU, which is determined by the CU according to the current service type of the user terminal, and the second configuration parameter at least includes: the initial cell ID, uplink and downlink signal frequency, uplink and downlink ratio, subcarrier spacing, MIMO mode, that is, the type of the second configuration parameter is the same as the first configuration parameter.

Referring to fig. 6, another system architecture that is applicable to the network configuration method provided in the embodiment of the present application is shown, where a CU is deployed in a central machine room, a DU is deployed in an access machine room, the CU and the DU can transmit information through an interface on a switch, the CU is deployed on general hardware based on a Virtual Network Feature (VNF) technology, the general hardware resources are storage resources, computing resources, and network resources, a virtualization layer is to virtualize the general hardware resources into a resource pool through the VNF technology, and a plurality of DUs connected to the CU can share resources in the resource pool.

As shown in fig. 6, the CU VNF layer includes a Control Plane (CP) responsible for handling control-related signaling content; a User Plane (UP) responsible for processing user plane data content; the interface processes the content related to the DU interface and the core network interface; the operation, administration and maintenance (OAM) module is responsible for network management configuration, status monitoring, alarm processing, and other contents.

In addition, there are many kinds of existing 5G terminal services, including large connection services (such as connection of shared single vehicles), low latency services (such as car networking services), and high traffic services (such as video services), and the like, and different types of services all have their own characteristics, so the network configuration method provided in this embodiment of the present application may add an algorithm module in the function of the OAM module, where the algorithm module may obtain a large amount of historical data corresponding to the service type of the user terminal, before the CU obtains the first operation parameter of the DU and/or the first service performance parameter of the user terminal connected to the DU, according to an artificial intelligence algorithm, perform service type delineation on different types of services according to the characteristics of the existing service type, store the delineated template and the service parameter corresponding to the template in the preset database of the OAM module in advance, after the CU obtains the first service performance parameter and/or the first operation parameter from the DU, the OAM module can process and analyze the acquired parameters, match the current service type with a preset database, and determine a second configuration parameter according to a matching result; therefore, optionally, as shown in fig. 7, the specific step of determining, by the CU in step S107, the second configuration parameter according to the first service performance parameter includes: S10701-S10702:

s10701, searching the first template from a preset database according to the first service performance parameter.

The first template is a template corresponding to a service type matched with the first service performance parameter of the current user terminal in a preset database analyzed by the OAM module.

It should be noted that the first template at least includes a second service performance parameter matching the first service performance parameter.

S10702, determining the network configuration parameters corresponding to the first template as second configuration parameters.

Optionally, as shown in fig. 8, the specific step of determining, by the CU in step S107, the second configuration parameter according to the first operating parameter includes: S10711-S10712:

s10711, searching a second template from a preset database according to the first operation parameter.

The second template is a template corresponding to the service type matched with the first operation parameter of the current user terminal in the preset database analyzed by the OAM module.

It should be noted that the second template at least includes a second operating parameter matching the first operating parameter.

S10712, determining the network configuration parameters corresponding to the second template as second configuration parameters.

Optionally, as shown in fig. 9, the specific step of determining, by the CU in step S107, the second configuration parameter according to the first operating parameter and the first service performance parameter includes: S10721-S10722:

s10721, searching a third template from a preset database according to the first operation parameter and the first service performance parameter.

The third template is a template corresponding to the service type matched with the first operation parameter and the first service performance parameter of the current user terminal in the preset database analyzed by the OAM module.

It should be noted that the third template at least includes a second operation parameter matched with the first operation parameter and a second service performance parameter matched with the first service performance parameter.

S10722, determining the network configuration parameter corresponding to the third template as the second configuration parameter.

The network configuration method provided in this embodiment of the present application adds an algorithm module to a function of the OAM module, may then process and analyze the obtained parameters, match the current service type with a preset database, and determine the second configuration parameter according to a matching result, which needs to be described that, in practical application, the second configuration parameter may also be determined in other manners.

S108, the CU sends a first updating instruction carrying the second configuration parameters to the DU.

Specifically, step S108 is one of the specific implementations of S307 in fig. 11.

Since the second configuration parameter is a parameter corresponding to the service type of the current user terminal, after the CU determines the second configuration parameter according to the template in the preset database, the CU may send a first update instruction carrying the second configuration parameter to the DU, where the first update instruction is at least used to instruct the DU to update the network configuration of the DU according to the second configuration parameter.

S109, the DU receives a first updating instruction which is sent by the CU and carries a second configuration parameter.

Specifically, step S109 is one of the specific implementations of S308 in fig. 11.

And S1010, updating the network configuration of the DU according to the second configuration parameter.

Since the second configuration parameter is an optimization parameter determined by the CU according to the current service type of the user terminal and specific to the current operating state of the DU, after the DU receives a first update instruction carrying the second configuration parameter sent by the CU, the initial network configuration can be updated to a configuration that makes the performance of the current operating state of the DU better according to the instruction of the first update instruction, so as to ensure that the current network configuration can provide better service quality for the service of the user terminal.

Optionally, as shown in fig. 10, an embodiment of the present application further provides another network configuration method, where the method may include S201 to S2012:

s201, the CU sends a configuration instruction carrying the first configuration parameter to a DU connected with the CU. S202, the DU receives a configuration instruction which is sent by the CU and is connected with the DU and carries the first configuration parameter.

S203, the DU completes the network configuration to the DU according to the first configuration parameter.

S204, the DU sends a configuration completion message to the CU.

S205, the CU receives the configuration completion message sent by the DU.

S206, the CU acquires a first operation parameter of the DU and/or a first service performance parameter of the user terminal connected with the DU.

S207, DU receives the target request sent by CU.

The target request is used for requesting a first operation parameter of a DU and/or a first service performance parameter of a user terminal connected with the DU from the DU by the CU.

S208, the DU sends the target response to the CU.

When the target request is used for the CU to request the first operation parameter of the DU from the DU, the target response carries the first operation parameter; and when the target request is used for the CU to request the first service performance parameter of the user terminal connected with the DU from the DU, the target response carries the first service performance parameter.

S209, the CU determines a second configuration parameter according to the first service performance parameter and/or the first operation parameter.

And S2010, when the CU determines that the first parameter in the second configuration parameter is different from the second parameter in the first configuration parameter, sending a first updating instruction to the DU, or sending a second updating instruction carrying the first parameter to the DU.

Because the OAM module may search for a corresponding template from a preset database according to the first operation parameter of the DU and/or the first service performance parameter of the user terminal connected to the DU, determine the second configuration parameter, where the second configuration parameter and the first configuration parameter are the same type of parameter, the second configuration parameter may be compared with the first configuration parameter sent by the initial CU to the DU, determine the second parameter in the first configuration parameter different from the first parameter in the second configuration parameter, and send the first update instruction to the DU, or send the second update instruction carrying the first parameter to the DU.

The first update instruction is at least used for indicating the DU to update the network configuration of the DU according to the second configuration parameter; the second update instruction is at least used for instructing the DU to update the network configuration of the DU according to the first parameter.

It should be noted that the names of the second parameter and the first parameter are the same; illustratively, when a CU determines that the uplink-downlink ratio in the second configuration parameter is different from the uplink-downlink ratio in the first configuration parameter, the CU may send a first update instruction to the DU, where the first update instruction is used to instruct the DU to update the network configuration of the DU according to the second configuration parameter, and the CU may also send a second update instruction carrying the uplink-downlink ratio to the DU, where the second update instruction may instruct the DU to update the uplink-downlink ratio corresponding to the second parameter in the initial network configuration to the uplink-downlink ratio corresponding to the first parameter, where at this time, the second parameter and the first parameter are both the uplink-downlink ratio, but specific values are different.

S2011, the DU receives the first update instruction with the second configuration parameter or the second update instruction with the first parameter sent by the CU.

S2012, the DU updates its own network configuration according to the second configuration parameter or according to the first parameter.

In order to more clearly illustrate the network configuration method provided in the embodiments of the present application, several embodiments will be specifically described below in detail.

The first embodiment is as follows: the first parameter and the second parameter are uplink and downlink proportion or uplink and downlink resource utilization rate.

In this embodiment, that is, when the CU sends a configuration instruction carrying a first configuration parameter to a DU connected to the CU through an F1 interface, the uplink and downlink configuration included in the first configuration parameter generally indicates that the downlink resource configuration occupies a larger ratio, and therefore, when the CU obtains the first service performance parameter of the user terminal, the uplink throughput is larger in the uplink throughput and the downlink throughput, it indicates that the user terminal at this time performs more uplink services.

Exemplarily, because there are many mechanical devices in a factory, parameters of a real-time operation state of the mechanical device need to be reported continuously, and a downlink only needs to execute some configuration commands, so that a requirement of an uplink resource allocation is large, when a DU covers a certain factory, uplink throughput of most user terminals in a first service performance parameter obtained by a CU is greater than corresponding downlink throughput, so that an uplink-downlink allocation in a second configuration parameter determined by the CU is different from an uplink-downlink allocation in an initial first configuration parameter, the CU may send the second configuration parameter to the DU, the DU performs network configuration again according to the second configuration parameter, the CU may also only send the uplink-downlink allocation in the second configuration parameter to the DU, and at this time, the DU only needs to correct the uplink-downlink allocation in the initial network configuration.

Example two: the first parameter and the second parameter are a location and channel model.

Because the MIMO mode can be switched according to different application scenarios, when the DU covers a high-rise building, the CU determines that the current MIMO mode cannot optimize the service performance according to the position and the channel model in the acquired first service performance parameter, that is, the MIMO mode in the second configuration parameter is different from the MIMO mode in the initial first configuration parameter, the CU can send the second configuration parameter to the DU, the DU performs network configuration again according to the second configuration parameter, the CU can also only send the MIMO mode in the second configuration parameter to the DU, and at this time, the DU only needs to change the MIMO mode in the initial network configuration to the MIMO mode corresponding to the first parameter.

Example three: the first parameter and the second parameter are sleep duration.

When the connection rate with the user terminal at a certain moment is close to 0, it indicates that no user terminal is running service at the moment, and at this time, a specific dormancy duration can be set so as to realize energy saving of the DU device.

For example, the initial dormancy duration may be 0, when the CU determines that the dormancy duration can be set according to the connection rate with the user terminal in the acquired first operation parameter or according to the historical data in the historical database in the OAM module, the CU may send the second configuration parameter to the DU, the DU performs network configuration again according to the second configuration parameter, the CU may also only send the dormancy duration in the second configuration parameter to the DU, and at this time, the DU only needs to correct the dormancy duration in the initial network configuration to the dormancy duration corresponding to the first parameter.

Certainly, in practical application, the first parameter and the second parameter may also be other types of parameters, for example, when the error rate in the first service performance parameter obtained by the CU is very high, the OAM module of the CU may analyze the reason that the error rate is high, and obtain a processing scheme for the analyzed reason; for another example, when the user terminal acquired by the CU is on a fast moving high-speed rail, that is, the moving speed is fast, some corresponding optimizations may be performed for such a scenario, the modulation scheme may be modified, or the number of times of repeatedly sending data may be increased, so as to ensure the reliability of the data.

In the network configuration method provided in the embodiment of the present application, a CU may first send a configuration instruction carrying a first configuration parameter to a DU connected to the CU, where the configuration instruction may instruct the DU to perform initial network configuration on itself according to the first configuration parameter, then the CU may determine a second configuration parameter according to an acquired first operation parameter of the DU and/or a first service performance parameter of a user terminal connected to the DU, and send a first update instruction carrying the second configuration parameter to the DU, where the first update instruction may instruct the DU to update the initial network configuration of the DU according to the second configuration parameter. According to the network configuration method provided by the application, the CU can determine the second configuration parameter according to the first service performance parameter and/or the first operation parameter, and the second configuration parameter is the optimization parameter determined by the CU and aiming at the DUs in different scenes, so that the first updating instruction which is sent to the DU by the CU and carries the second configuration parameter can instruct the DU to update the initial network configuration to the network configuration which enables the current operation performance of the DU to be better, the requirements of the DU in different scenes are met, and the flexibility of the network configuration of the DU is improved.
