Description

Wireless parameter adjusting method and device

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for adjusting wireless parameters.

Background

In the radio parameter adjustment scheme, different performance optimization schemes for adjusting radio parameters are generally designed with a specific Key Performance Indicator (KPI) as a target. For example, a pilot power adjustment scheme, a handover parameter optimization scheme, a voice over long-term evolution (VOLTE) optimization parameter scheme, an energy saving scheme, and the like in the prior art. However, the above-mentioned several radio parameter adjustment schemes can only guarantee specific KPIs in the wireless network.

In the third generation partnership project (3) ^rd generation partial nershirp project, 3GPP) introduces network data analysis (NWDA) network elements, and defines the policy related to parameter analysis in the wireless network. However, no relevant method for guaranteeing KPIs in wireless networks is currently available in 3GPP protocols.

Therefore, in the current wireless parameter adjustment scheme, a wireless parameter adjustment method for guaranteeing the KPI in the wireless network is needed, which can effectively guarantee the total KPI of the wireless network during the adjustment of the wireless parameters and improve the wireless performance.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings. The particular methods of operation in the method embodiments may also be applied in device embodiments or system embodiments.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: long Term Evolution (LTE) systems, Worldwide Interoperability for Microwave Access (WiMAX) communication systems, future fifth Generation (5th Generation, 5G) systems, such as new radio access technology (NR), and future communication systems, such as 6G systems.

This application is intended to present various aspects, embodiments, or features around a system that may include a number of devices, components, modules, and the like. It is to be understood and appreciated that the various systems may include additional devices, components, modules, etc. and/or may not include all of the devices, components, modules etc. discussed in connection with the figures. Furthermore, a combination of these schemes may also be used.

In addition, in the embodiments of the present application, the word "exemplary" is used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the word using examples is intended to present concepts in a concrete fashion.

In the embodiment of the present application, information (information), signal (signal), message (message), channel (channel) may be mixed, and it should be noted that the intended meanings are consistent when the differences are not emphasized. "of", "corresponding", "canceling" and "corresponding" may sometimes be used in combination, and it should be noted that the intended meaning is consistent when differences are not emphasized.

The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The embodiment of the application can be applied to a traditional typical network, and can also be applied to a future UE-centric (UE-centric) network. A UE-centric network introduces a network architecture without a cell (Non-cell), that is, a large number of small stations are deployed in a certain area to form a super cell (super cell), each small station is a Transmission Point (TP) or a Transmission and Reception Point (TRP) of the super cell, and is connected to a centralized controller (controller). When the UE moves in the Hyper cell, the network side equipment selects a new sub-cluster for the UE to serve, thereby avoiding real cell switching and realizing the continuity of UE service. The network side device comprises a wireless network device. Or, in a network with UE as the center, multiple network side devices, such as small stations, may have independent controllers, such as distributed controllers, each small station can independently schedule users, and there is interactive information between small stations over a long term, so that there is also a certain flexibility when providing cooperative service for UE.

In the embodiment of the present application, different base stations may be base stations with different identities, and may also be base stations with the same identity and deployed in different geographic locations. Since before the base station is deployed, the base station does not know whether the base station relates to a scenario applied in the embodiment of the present application, therefore, the base station or the baseband chip should support the method provided in the embodiment of the present application before the base station is deployed. It is to be understood that the aforementioned base stations with different identities may be base station identities, cell identities, or other identities.

Some scenarios in the embodiment of the present application are described by taking a scenario of an NR network in a wireless communication network as an example, it should be noted that the scheme in the embodiment of the present application may also be applied to other wireless communication networks, and corresponding names may also be replaced by names of corresponding functions in other wireless communication networks.

For the convenience of understanding the embodiments of the present application, a communication system applicable to the embodiments of the present application will be first described in detail by taking the communication system shown in fig. 1 as an example. Fig. 1 shows a schematic diagram of a communication system suitable for the communication method of the embodiment of the present application. As shown in fig. 1, the communication system 100 includes a network device 102 and a terminal device 106, where the network device 102 may be configured with multiple antennas and the terminal device may also be configured with multiple antennas. Optionally, the communication system may further include the network device 104, and the network device 104 may also be configured with multiple antennas.

It should be understood that network device 102 or network device 104 may also include a number of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, etc.).

The network device is a device with a wireless transceiving function or a chip that can be set in the device, and the device includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), wireless fidelity (WIFI) system Access Point (AP), wireless relay Node, wireless backhaul Node, transmission point (TRP or transmission point, TP), etc., and may also be 5G, such as NR, a gbb in the system, or a transmission point (TRP or TP), a set (including multiple antennas) of a base station in the 5G system, or a panel of a base station (including multiple antennas, or a BBU) in the 5G system, or, Distributed Units (DUs), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may further include a Radio Unit (RU). The CU implements part of the function of the gNB, and the DU implements part of the function of the gNB, for example, the CU implements Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) layers, and the DU implements Radio Link Control (RLC), Medium Access Control (MAC) and Physical (PHY) layers. Since the information of the RRC layer is eventually converted into or from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU or the DU + CU under this architecture. It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.

The RAN equipment can realize the functions of protocol layers such as RRC, PDCP, RLC, MAC and the like by one node; or the functions of these protocol layers may be implemented by multiple nodes; for example, in an evolved structure, the RAN device may include a CU and a DU, and a plurality of DUs may be centrally controlled by one CU. The CU and the DU may be divided according to protocol layers of the radio network, for example, functions of a PDCP layer and above protocol layers are provided in the CU, and functions of protocol layers below the PDCP layer, for example, functions of an RLC layer and a MAC layer, are provided in the DU.

This division of the protocol layers is only an example, and it is also possible to divide the protocol layers at other protocol layers, for example, at the RLC layer, and the functions of the RLC layer and the protocol layers above are set in the CU, and the functions of the protocol layers below the RLC layer are set in the DU; alternatively, the functions may be divided into some protocol layers, for example, a partial function of the RLC layer and a function of a protocol layer above the RLC layer may be provided in the CU, and the remaining function of the RLC layer and a function of a protocol layer below the RLC layer may be provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU.

In addition, the radio frequency device may be pulled away, not placed in the DU, or integrated in the DU, or partially pulled away and partially integrated in the DU, which is not limited herein.

Referring to the network architecture shown in fig. 2, the Control Plane (CP) and the User Plane (UP) of a CU may also be implemented separately and separated into different entities, respectively a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity).

In the above network architecture, the signaling generated by the CU may be sent to the terminal device through the DU, or the signaling generated by the terminal device may be sent to the CU through the DU. The DU may pass through the protocol layer encapsulation directly to the terminal device or CU without parsing the signaling. In the following embodiments, if transmission of such signaling between the DU and the terminal device is involved, in this case, the transmission or reception of the signaling by the DU includes such a scenario. For example, the signaling of the RRC or PDCP layer is finally processed as the signaling of the PHY layer to be sent to the terminal device, or is converted from the received signaling of the PHY layer. Under this architecture, the signaling of the RRC or PDCP layer can also be considered as being sent by the DU, or sent by the DU and the radio bearer.

In the above embodiment, the CU may be divided into the network devices on the RAN side, and the CU may also be divided into the network devices on the CN side, which is not limited herein.

The apparatus in the following embodiments of the present application may be located in a terminal device or a network device according to the functions implemented by the apparatus. When the above structure of CU-DU is adopted, the network device may be a CU node, or a DU node, or a RAN device including the CU node and the DU node.

A terminal device may also be referred to as a User Equipment (UE), an access terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal device, a mobile device, a user terminal device, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self driving (self driving), a wireless terminal device in remote medical (remote medical), a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety, a wireless terminal device in city (city), a wireless terminal device in smart home (smart home), and the like. The embodiments of the present application do not limit the application scenarios. In the present application, a terminal device having a wireless transceiving function and a chip that can be installed in the terminal device are collectively referred to as a terminal device.

In the communication system 100, the network device 102 and the network device 104 may each communicate with a plurality of terminal devices (e.g., the terminal device 106 shown in the figure). Network device 102 and network device 104 may communicate with one or more terminal devices similar to terminal device 106. It should be understood that the terminal device communicating with network device 102 and the terminal device communicating with network device 104 may be the same or different. The terminal device 106 shown in fig. 1 may communicate with both the network device 102 and the network device 104, but this only illustrates one possible scenario, and in some scenarios, the terminal device may only communicate with the network device 102 or the network device 104, which is not limited in this application.

It should be understood that fig. 1 is a simplified schematic diagram of an example for ease of understanding only, and that other network devices or other terminal devices may also be included in the communication system, which are not shown in fig. 1.

In a wireless network environment, when optimizing network KPIs, wireless parameters of a cell need to be continuously adjusted to obtain optimal wireless network performance. In the embodiment of the application, the reinforcement learning is applied to the wireless network parameter adjusting scheme. Reinforcement learning is the act of an agent (agent) taking a series of actions in an environment to get the maximum cumulative return. Because reinforcement learning has no direct guiding information, the intelligent agent needs to continuously interact with the environment, and the optimal strategy is obtained through various trying ways. By reinforcement learning, an agent can know what actions should be taken in what states. The reinforcement learning process is explained in detail below.

An reinforcement learning process typically includes the following three tuples:

s: represents a set of states (state) with s _i ∈S，s _i Indicating the state of the ith step;

a: represents a set of actions (actions) having a _i ∈A，a _i An action representing the ith step;

r: s × A → R, R is a reward function (reward function). If one group(s) ₁ ,a ₁ ) Move to the next state s ₂ Then the reward function can be denoted as r(s) ₂ |s ₁ ,a ₁ ). If(s) ₁ ,a ₁ ) Corresponding next state s ₂ Is unique, then the reward function can also be denoted as r(s) ₁ ,a ₁ )。

The process of reinforcement learning can be represented as a markov decision process: an agent has an initial state s ₀ Then pick an action a from A ₀ Execution, post-execution Environment (Environment) transfer to the next s ₁ State, then performs an action a ₁ The environment is transferred to s ₂ And so on.

There are many parameters in Radio Resource Management (RRM) and not few are default and fixed, and the default parameter setting is not optimal for each cell and cannot maximize the wireless network efficiency. For example, changes in the user's mobility and traffic patterns also require changes in the radio parameters. Therefore, the aforementioned reinforcement learning can be used for the adjustment of the wireless parameters to find the optimal wireless parameters. For example, reinforcement learning may be applied to a plurality of wireless functions such as pilot adjustment, antenna tilt and azimuth adjustment.

The state set, action and reward functions required by the wireless network can be predefined in the design stage, and the defined algorithm is used for wireless parameter adjustment. However, this approach is not flexible enough to modify and adjust the algorithm and does not give the state set, actions and reward functions that are most suitable for the system. On the other hand, the wireless network has strict requirements on KPI, and the KPI cannot be greatly reduced in the parameter adjustment process. Therefore, it is often also necessary to introduce KPI assurance policies. In the prior art, different performance optimization schemes for adjusting wireless parameters are generally designed with specific KPIs as targets. However, such a radio parameter adjustment scheme can guarantee a specific KPI in a wireless network only in a specific scheme. In addition, a parameter analysis related policy in a wireless network is defined in the 3GPP protocol. However, no relevant method for guaranteeing KPIs in wireless networks is currently available in 3GPP protocols.

Therefore, a wireless parameter adjustment method for guaranteeing the KPIs in the wireless network is needed, which can effectively guarantee the total KPIs of the wireless network during the adjustment of the wireless parameters and improve the performance of the wireless network.

Based on the above requirements, an embodiment of the present application provides a method for adjusting wireless parameters. Fig. 3 is an exemplary flowchart of a wireless parameter adjustment method provided in an embodiment of the present application, which is shown from the perspective of device interaction. As shown in fig. 3, the method may include the steps of:

step 301: the network data analysis unit NWDA obtains KPIs and data of said KPIs from the network management system NMS. It should be noted that, for a system without NWDA definition, a module with analysis on wireless data may be regarded as an NWDA network element.

The KPI is a wireless network index concerned by network operation and maintenance personnel. May include, but is not limited to, radio access rates that reflect the success rate of the UE accessing the network. Alternatively, the KPI may also include a handover success rate, which is a very important function of the mobile communication system, and the handover success rate is used to identify a success rate of the UE for maintaining continuous call when the UE is handed over from different cells. Alternatively, the KPI may further include a radio call drop rate, which is used to indicate a proportion of the UE that is abnormally released.

In one possible implementation manner, network elements such as CUs and DUs in the wireless network environment report information such as wireless parameters and parameter values of each cell to the NMS, so that the NMS determines KPIs in the wireless network environment according to the information such as the wireless parameters and parameter values. For a cell, the wireless parameters may include pilot power, pilot ratio, antenna downtilt, antenna azimuth, load of the cell and neighboring cells, number of users, Reference Signal Received Power (RSRP), and the like, and corresponding parameter values.

Step 302: and the network data analysis unit NWDA determines KPI data information according to the KPI and the KPI data. The KPI data information may include a first KPI that needs to be guaranteed and a threshold corresponding to the first KPI.

In one possible implementation, the NWDA may determine the current network scenario according to the obtained KPI. And determining KPI data information corresponding to the current network scene according to the corresponding relation between the preset network scene and the KPI data information.

Under different network scenes, different KPI guarantee information can be preset according to experience values. The network scenario here may be a different geographical location, such as an urban area, a suburban area, etc. For example, the KPI guarantee information of an urban area may include a threshold of a radio access rate of 98% and a threshold of a handover success rate of 98%; the KPI guarantee information of the suburbs may include that the threshold of the wireless access rate is 90%, the threshold of the handover success rate is 90%, and the like. Or, the network scenario may be of different network sizes, such as many access UEs, fewer access UEs, and the like. The number of the accessed UEs may be determined by a preset threshold, for example, if the number of the accessed UEs is greater than or equal to the threshold, it may be determined that there are many accessed UEs, and if the number of the accessed UEs is less than the threshold, it may be determined that there are few accessed UEs. For example, when the UE is greater than or equal to the threshold, the KPI guarantee information may include that the threshold of the radio access rate is 98%, the threshold of the handover success rate is 98%, and the threshold of the radio drop call rate is 0.1%; when the accessed UE is smaller than the threshold, the KPI guarantee information may include that the threshold of the radio access rate is 95%, the threshold of the handover success rate is 96%, and the threshold of the radio drop-call rate is 0.2%. Or, the network scenario may also be different service experience requirements, such as a requirement that the UE is a call, or a requirement that the UE is a data connection, and the like.

In another example, different network scenarios may also preset the same KPI safeguard information, or different network scenarios may preset partially the same KPI safeguard information.

In another possible implementation, the NWDA may further obtain preset KPI data information. The KPI data information is predetermined according to an empirical value, and is not specifically limited in the present application.

Step 303: and the network data analysis unit NWDA sends the KPI data information to a centralized unit CU.

Step 304: the centralized unit CU acquires a first KPI corresponding to each cell in at least one cell in a wireless network.

In one possible implementation, a CU may send a KPI data request to the NMS. The KPI request comprises an identifier of each cell in at least one cell and first KPI indication information required to be acquired. The NMS may obtain the first KPI of each cell in the at least one cell according to the first KPI indication information, and send the obtained first KPI to the CU.

In another possible implementation, the KPI request further includes a data time length and a data time interval. The data time duration may be a KPI of a certain time duration, for example, a KPI of a cell within 10 s. The data time interval may be a KPI at a particular interval period, such as may be a KPI per second, a KPI per minute, an KPI per hour, and so forth.

For example, the KPI data request sent by the CU to the NMS includes cell1, cell2, and the first KPI indication information is radio access rate and handover success rate, data time length is 5s, and data time interval is 1 s. The NMS obtains the radio access rate and handover success rate of cell1 and cell2 up to 5 s. Wherein, the wireless access rate and the switching success rate are all per second.

Step 305: and the centralized unit CU compares the first KPI of each cell with the threshold respectively to obtain a target cell needing to be subjected to wireless parameter adjustment.

In a possible implementation manner, the CU compares the first KPI of each cell with a threshold, and takes each cell whose first KPI does not satisfy the threshold as a target cell. In an example, the CU may use each cell in which all the first KPIs do not satisfy the threshold as a target cell for performing radio parameter adjustment. In another example, the CU may take each cell for which part of the first KPI does not satisfy the threshold as a target cell for which radio parameter adjustment is required.

For example, the KPI data information acquired by the CU includes that the threshold of the radio access rate is 98%, the radio access rate acquired by the cell1 is 95%, the radio access rate acquired by the cell2 is 98%, and the radio access rate acquired by the cell3 is 98.5%. The CU determines that the target cell for which the radio parameter adjustment is required is cell 1. For another example, the KPI data information acquired by the CU includes that the threshold of the radio access rate is 97%, the handover success rate is 98%, the radio access rate acquired by the cell1 is 98%, the handover success rate is 97%, the radio access rate of the cell2 is 98%, the handover success rate is 98.5%, the radio access rate of the cell3 is 96%, and the handover success rate is 96%, so that the CU may determine that the cell1 and the cell2 are target cells requiring radio parameter adjustment.

In another possible implementation manner, if there are at least two cells that can be combined into one combined cell in at least one cell, the CU determines whether the first KPI of the combined cell satisfies the threshold according to the threshold of the first KPI. If the first KPI of the combined cell does not satisfy the threshold, the CU determines whether the first KPI of each cell in the combined cell satisfies the threshold. The CU uses each cell which does not satisfy the threshold as a target cell.

The combined cell may be pre-stored in the CU, or may be acquired by the CU from the NWDA.

It should be noted that the first KPI of the combined cell may be obtained according to the first KPI of each cell in the combined cell. For example, the first KPI of the combined cell may be an average of the first KPIs of each cell in the combined cell.

In an example, the CU may determine whether the first KPI of each cell in the combined cell satisfies the threshold when all first KPIs of the combined cell do not satisfy the threshold. In another example, the CU may determine whether the first KPI of each of the combined cells satisfies the threshold when a portion of the first KPIs of the combined cells do not satisfy the threshold.

For example, cell1 and cell2 and cell3 are combined cell a, and cell4 and cell5 are combined cell b. The KPI data information acquired by the CU comprises that the threshold of the wireless connection rate is 98% and the switching success rate is 97%. The wireless access rate of the CU for obtaining the cell1 is 98.3%, the switching success rate is 97%, the wireless access rate of the cell2 is 99%, the switching success rate is 96%, the wireless access rate of the cell3 is 98.7%, the switching success rate is 95%, the wireless access rate of the cell4 is 97.4%, the switching success rate is 99%, the wireless access rate of the cell5 is 99.2%, and the switching success rate is 97%. The CU determines that the radio access rate of the combined cell a is 98.6%, the handover success rate is 96%, the radio access rate of the combined cell b is 98.3%, and the handover success rate is 98%. Since the first KPI of combined cell a does not satisfy the threshold, the CU compares the first KPI of each cell in combined cell a with the threshold. The CU may determine that cell2 and cell3 are target cells for which radio parameter adjustment is required.

Step 306: the centralized unit CU sends the identity of the target cell to the distributed unit DU.

In an example, a CU may send an identity of a target cell to a DU, which adjusts radio parameters of the target cell. In another example, the CU may send the DU an identification of the target cell and a first KPI of the first KPIs of the target cell that does not meet the threshold.

Step 307: the distributed unit DU adjusts radio parameters of the target cell.

In one possible implementation, the CU may perform a fallback operation or a forward operation on the radio parameters of the target cell when applying reinforcement learning to the radio parameter adjustment scheme. The rollback operation may be a rollback preset step, and for example, may be a rollback one step, or may be a rollback two steps, or the like. Similarly, the advance operation may be a preset step, for example, one step or two steps.

For example, when adjusting wireless parameters, the agent performs a ₂ And the CU acquires a target cell in the wireless network as a cell2 and sends a cell2 to the DU. At this point, the DU may cause the agent to perform a ₂ Action preceding action, e.g. an agent may be caused to perform a ₁ Act or cause agent to perform a ₀ And (6) acting.

In the embodiment of the present application, after the DU adjusts the radio parameters of the target cell, the adjustment result of the target cell may be sent to the CU. The adjustment result may include the adjusted wireless parameters and the adjusted parameter values in the wireless network.

In one possible implementation, the CU may send the adjustment result to the NWDA. And the NWDA re-determines the KPI data information according to the wireless parameters and the parameter values in the adjustment result. The NWDA may determine the current network scenario according to the wireless parameters and parameter values in the wireless network. And KPI data information can be determined again according to the network scene.

In another possible implementation, the CU may send the adjustment results to the NMS. The NMS may update the first KPI based on wireless parameters and parameter values in the wireless network. For example, the wireless access rate in the first KPI in the wireless network is 97%, and after receiving the adjustment result, the updated wireless access rate is 97.5% according to the wireless parameters and parameter values in the wireless network.
