Description

Technical Field

[0001] This invention relates to the field of communications, specifically to a method, apparatus, network device, and storage medium for optimizing cell configuration information. Background Technology

[0002] In communication networks, when the cell configuration information of a cell under a network management device conflicts with that of other cells, the cell configuration information of that cell needs to be reconfigured and optimized to resolve the conflict. However, current cell configuration optimization technologies can only consider whether the cell configuration information selected for the cell to be optimized conflicts with the cell configuration information of other cells within the jurisdiction of the network management device when reconfiguring the cell configuration information. They fail to consider whether the selected cell configuration information conflicts with the cell configuration information of other cells outside the jurisdiction of the network management device. This results in conflicts between the cell configuration information reassigned to the cell to be optimized and the cell configuration information of other cells outside the jurisdiction of the network management device, leading to repeated reallocation of cell configuration information for the cell to be optimized. Consequently, this results in low cell optimization efficiency and accuracy, impacting network performance. Summary of the Invention

[0003] The present invention provides a method, apparatus, network device, and storage medium for optimizing cell configuration information. It aims to solve the problem in related technologies where the cell configuration information reassigned to the cell to be optimized conflicts with the cell configuration information of other cells outside the jurisdiction of the network management device. This leads to the need to repeatedly reassign cell configuration information to the cell to be optimized, resulting in low cell optimization efficiency and accuracy, and affecting network performance.

[0009] The restricted usage list includes cell configuration information of cells outside the jurisdiction of the network management device, while the cell configuration information allocated to the cell to be optimized is not in the restricted usage list.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the embodiments of this invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] Example 1:

[0027] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0028] In related technologies, there are situations where the cell configuration information reallocated to a cell to be optimized conflicts with the cell configuration information of other cells outside the jurisdiction of the network management device. This embodiment addresses this issue by first obtaining a restricted usage list of the network management device corresponding to the cell to be optimized before allocating cell configuration information. This restricted usage list includes cell configuration information of cells outside the jurisdiction of the network management device. Then, based on the obtained restricted usage list of the network management device corresponding to the cell to be optimized, a cell configuration information is allocated to the cell to be optimized from the available configuration information list of the cell to be optimized, and this allocated cell configuration information is not in the restricted usage list. This ensures that the cell configuration information allocated to the cell to be optimized will not conflict with the cell configuration information of other cells outside the jurisdiction of the network management device, avoiding the need for repeated reallocation of cell configuration information for the cell to be optimized, thereby improving cell optimization efficiency and accuracy, and enhancing network performance. For ease of understanding, this embodiment will be further explained below in conjunction with... Figure 1 The cell configuration information optimization method provided in this embodiment is illustrated as an example. Please refer to [link / reference]. Figure 1 As shown, it includes, but is not limited to:

[0029] S101: Obtained cell to be optimized.

[0030] In this embodiment, the cells to be optimized may include cells that meet the set optimization conditions. These optimization conditions can be flexibly set according to specific application requirements. For example, in some examples, the optimization condition may be a cell whose configuration information conflicts with that of other cells. In this example, the cells to be optimized include cells whose configuration information conflicts with that of other cells.

[0031] For example, in other examples, the optimization condition may include the cell that received the optimization instruction, which may be issued by the user to the network element or network management device, or by other management devices to the network element or network device.

[0032] It should be understood that the cell configuration information in this embodiment may include various configuration information that cannot conflict with other cells, such as at least one of the cell's Physical Cell Identifier (PCI) and Random Access Channel (RACH) root sequence.

[0033] S102: Based on the obtained list of restricted network management devices corresponding to the cell to be optimized, allocate a cell configuration information for the cell to be optimized from the cell configuration information included in the list of available configuration information of the cell to be optimized;

[0034] The restricted usage list corresponding to the cell to be optimized includes cell configuration information of cells outside the jurisdiction of the network management equipment of the cell to be optimized. The cell configuration information allocated to the cell to be optimized in S102 is not in the restricted usage list, which can ensure that the cell configuration information allocated to the cell to be optimized will not conflict with the cell configuration information of other cells outside the jurisdiction of the network management equipment, avoid the need to repeatedly reallocate cell configuration information for the cell to be optimized, thereby improving the efficiency and accuracy of cell optimization and improving network performance.

[0035] In some examples of this embodiment, the restricted list of the network management device corresponding to the cell to be optimized may include, but is not limited to, the cell configuration information of the neighboring cells of the cell to be optimized that are outside the jurisdiction of the network management device. The cell configuration information of the neighboring cells may include, but is not limited to, at least one of the one-dimensional neighbor cells and two-dimensional neighbor cells of the cell to be optimized.

[0036] In some examples of this embodiment, before allocating a cell configuration information to the cell to be optimized from the cell configuration information included in the available configuration information list of the cell to be optimized, based on the obtained restricted usage list of the network management device corresponding to the cell to be optimized, at least one of the following processes for obtaining the restricted usage list is also included:

[0037] Based on the received restricted usage list configuration information, the restricted usage list is obtained. This restricted usage list configuration information can be issued by, but is not limited to, the user. In some examples, the issued restricted usage list configuration information can directly include the configured restricted usage list. In other examples, the issued restricted usage list configuration information can include the cell configuration information of neighboring cells. Cell configuration information can be extracted from the received restricted usage list configuration information and added to the restricted usage list.

[0038] The network element acquires detection information for cells outside the jurisdiction of the network management equipment and obtains a restricted usage list based on the detection information. For example, when the cell configuration information includes PCI, the network element can detect the PCI of neighboring cells of the cell to be optimized through, but is not limited to, user equipment (UE); when the cell configuration information includes random access channel root sequences, the network element can detect the random access channel root sequences of neighboring cells of the cell to be optimized.

[0039] Optionally, in some instances of this embodiment, to further improve the accuracy of cell configuration information allocation, after obtaining the restricted usage list, the cell configuration information in the restricted usage list can be dynamically updated. For example, the restricted usage list can be dynamically updated by dynamically (either periodically or irregularly) distributing the restricted usage list configuration information.

[0040] For example, when obtaining detection information from cells outside the jurisdiction of network management equipment, and using this detection information to obtain a restricted usage list, the following may be included, but are not limited to:

[0041] Dynamically acquire (can be acquired in real time or not; when not acquired in real time, can be acquired periodically or not periodically, depending on the application scenario) detection information; when the detection information includes a new cell outside the jurisdiction of the network management device, add the cell configuration information of the new cell to the restricted use list.

[0042] Dynamically acquire detection information. When the detection information includes a previously existing cell outside the jurisdiction of the network management device that has been deleted, remove the cell configuration information of the deleted cell from the restricted usage list.

[0043] The dynamically updated restricted usage list provides accurate cell configuration information outside the network management device's jurisdiction, thereby improving the accuracy of subsequent cell configurations. This prevents conflicts between the cell configuration information allocated to the cell to be optimized and the cell configuration information of other cells outside the network management device's jurisdiction, thus improving cell optimization efficiency and network performance.

[0044] In some instances of this example, the allocation of cell configuration information for the cell to be optimized from the available configuration information list of the cell to be optimized, based on the obtained list of restricted uses of the network management device corresponding to the cell to be optimized, can be done in any of the following ways, including but not limited to:

[0045] Method 1: See Figure 2 As shown, it includes, but is not limited to:

[0046] S201: From the available configuration information list of the cells to be optimized, filter out the cell configuration information that is not in the restricted usage list; that is, filter out the cell configuration information in the restricted usage list.

[0047] S202: From the filtered cell configuration information, select a cell configuration information that satisfies the allocation algorithm and assign it to the cell to be optimized.

[0048] Method 2: See Figure 3As shown, it includes, but is not limited to:

[0049] S301: From the list of available configuration information for cells to be optimized, first select the configuration information of each cell that satisfies the allocation algorithm.

[0050] S302: From the selected cell configuration information that satisfies the allocation algorithm, select a cell configuration information that is not in the restricted list and allocate it to the cell to be optimized.

[0051] Method 3: See Figure 4 As shown, it includes, but is not limited to:

[0052] S401: From the available configuration information list of the cells to be optimized, determine the cell configuration information that satisfies the allocation algorithm in sequence. The order of this step can be determined according to the order from beginning to end of the available configuration information list, from end to beginning, or a randomly selected order, etc.

[0053] S402: If the cell configuration information that satisfies the allocation algorithm is not in the restricted list, then allocate it to the cell to be optimized; otherwise, return to S401 until all cell configuration information in the available configuration information list of the cell to be optimized has been evaluated.

[0054] The above three allocation methods are merely examples of this embodiment. It should be understood that other variations can be made based on the above examples, all of which are within the scope of this embodiment and will not be elaborated here.

[0055] It should be understood that in this embodiment, the above-mentioned allocation of cell configuration information to the cell to be optimized from the cell configuration information included in the available configuration information list of the cell to be optimized, based on the obtained list of restricted use of network management devices corresponding to the cell to be optimized, can adopt a centralized allocation scheme or a distributed scheme. For ease of understanding, examples of the centralized allocation scheme and the distributed scheme are given below.

[0056] The centralized allocation scheme includes: the network management device receiving the cell information to be optimized sent by the network element device; the network management device determining the cell to be optimized based on the cell information; and allocating a cell configuration information to the cell to be optimized from the cell configuration information included in the available configuration information list of the cell to be optimized according to the restricted usage list of the network management device corresponding to the cell to be optimized. The specific selection method can be any of the methods in the above examples.

[0057] The distributed scheme includes: network element devices acquiring cells to be optimized; network element devices allocating cell configuration information for cells to be optimized from the available configuration information list of cells to be optimized, based on the restricted usage list of the network management device corresponding to the cell to be optimized; wherein the available configuration information list of the cell to be optimized is obtained by the network element devices from the network management device; the network management device can periodically or in real time when the available configuration information list is updated, and the network management device can also send the available configuration information list to the network element devices upon request.

[0058] As can be seen, in this embodiment, the restricted usage list of the network management device corresponding to the cell to be optimized can be obtained through methods not limited to those described above. When there is a cell to be optimized, a cell configuration information can be allocated to the cell to be optimized from the cell configuration information included in the available configuration information list of the cell to be optimized, based on the obtained restricted usage list of the network management device corresponding to the cell to be optimized. The allocated cell configuration information is not in the restricted usage list. This ensures that the cell configuration information allocated to the cell to be optimized will not conflict with the cell configuration information of other cells outside the jurisdiction of the network management device, avoiding the need to repeatedly reallocate cell configuration information for the cell to be optimized, thereby improving the efficiency and accuracy of cell optimization and improving network performance.

[0059] Example 2:

[0060] For ease of understanding, this embodiment, based on the above embodiments, also provides a cell configuration information optimization device. This cell configuration information optimization device can be installed in a network element device or in a network management device. See [link to relevant documentation]. Figure 5 As shown, it includes, but is not limited to:

[0061] The optimization processing module 501 is used to allocate a cell configuration information to the cell to be optimized from the cell configuration information included in the available configuration information list of the cell to be optimized, based on the obtained restricted usage list of the network management device corresponding to the cell to be optimized. The restricted usage list includes cell configuration information of cells outside the jurisdiction of the network management device, and the cell configuration information allocated to the cell to be optimized is not in the restricted usage list. For specific processing procedures, please refer to, but are not limited to, the process shown in the above embodiments, and will not be repeated here.

[0062] It should also be understood that the optimization processing module 501 in this embodiment can also be used, but is not limited to, performing other steps shown in the above embodiments. Furthermore, the function of at least one of the optimization processing modules 501 in this embodiment can be implemented by, but is not limited to, a processor in a network device.

[0063] This embodiment also provides a network device, which can be, but is not limited to, a network element device or a network management device. Please refer to [link to relevant documentation]. Figure 6 As shown, it includes a processor 601, a memory 602, and a communication bus 603 connecting the processor 601 and the memory 602;

[0064] The memory 602 stores a computer program that can be executed by a processor to implement the steps of the cell configuration information optimization method as shown in the above embodiment.

[0065] For ease of understanding, this embodiment uses PCI as an example for cell configuration information. When the cell configuration information includes a random access channel root sequence, the configuration process of the random access channel root sequence is similar to that of PCI and will not be repeated here. Of course, the cell configuration information may also include other information that can be configured using the example method provided in this embodiment.

[0066] In this example, the network management device enables network management, including the use, integration, and coordination of hardware, software, and manpower, in order to monitor, test, configure, analyze, evaluate, and control network resources. Furthermore, it can promptly report and handle network failures, and coordinate and maintain the efficient operation of the network system. The device that performs network management is referred to as the network management device in this example.

[0067] Network element device: It can be composed of one or more chassis or cabinets, and can independently complete certain transmission functions. It is an element in the network, a device in the network; in this example, the network element is the smallest unit that can be monitored and managed in network management.

[0068] Cell: In communications, the area covered by a wireless signal is called a cell. Generally, it refers to the range that the signal of a base station can cover. The range that the signal of a base station can cover can be divided into one cell or multiple cells.

[0069] User Equipment (UE): An important concept in communications, the user equipment is called UE. In this example, UE includes, but is not limited to, mobile phones, smart terminals, multimedia devices, streaming media devices, etc.

[0070] In this example, the network element can detect the PCI of one-dimensional and / or two-dimensional neighboring cells of the cell across network management devices through the UE and other means (it can also detect the PCI of other cells across network management devices as needed, which will not be elaborated here). The network element continuously detects and records the PCI of the neighboring cells of the cell across network management devices to form a PCI restricted list (i.e., a PCI usage restricted list), or manually intervenes to maintain the PCI restricted list. In this way, when adopting a centralized allocation scheme, the network management device obtains the PCI restricted list of the cell to be optimized when allocating PCI, and will not allocate the PCI in the PCI restricted list to the cell to be optimized, thereby avoiding the occurrence of new conflicts caused by newly allocated PCI in the case of cross-network management devices.

[0071] In this example, when the network element detects the PCI of one-dimensional neighbor cells and / or two-dimensional neighbor cells of the cell across network management devices through the UE or other means, the control of setting the PCI restricted list detection switch of the cell can be:

[0072] To better control and conserve resources, this switch can be turned on for cells located at the boundary of the network management device, and turned off for cells located in the central area of ​​the network management device. When performing PCI optimization, the surrounding neighboring cells of cells in the central area are also within the jurisdiction of the network management device, which can obtain information about these neighboring cells. Therefore, network elements do not need to initiate PCI restricted list detection, and the PCI allocated by the network management device will not cause new conflicts. Thus, it is unnecessary to turn on this switch for cells in the central area. However, when performing PCI optimization, some surrounding neighboring cells of cells located at the boundary of the network management device may be outside its jurisdiction. The network management device cannot obtain information about neighboring cells outside its jurisdiction. Therefore, network elements can activate the PCI restricted list detection switch to ensure that the PCI allocated by the network management device does not cause new conflicts or confusion.

[0073] Of course, in some application scenarios of this embodiment, this switch may not be set, and the detection of the restricted list may be automatically started by default across the entire network.

[0074] In this example, the network element can initiate automatic detection of the PCI restricted list:

[0075] In this example, when a network element detects a new PCI of a one-dimensional or two-dimensional neighbor cell on the same frequency, it can add this PCI to the PCI restricted list.

[0076] In this example, network elements can periodically or dynamically check whether a PCI in the restricted PCI list can be reassigned. Changes such as deleting the PCI from the restricted list, alterations to adjacency relationships, and additions or deletions of cells will all affect the PCIs in the restricted list. Network elements can periodically and in real-time monitor neighboring cell PCI information to dynamically maintain the real-time status of the restricted PCI list.

[0077] In this example, when a network element detects a cell conflict, it can report it to the network management device for global optimization. In this example, the neighboring cells that conflict with the cell are not limited to those within or outside the jurisdiction of the network management device (e.g., different vendors, different network management devices, etc.).

[0078] In this example, when the network management device performs PCI optimization, it first excludes PCIs from the restricted PCI list within the available PCI range. Then, it initiates filtering using various optimization algorithms. If no PCIs remain after filtering the restricted PCIs, the PCI allocation is considered a failure. If other available PCIs are available after filtering the restricted PCIs, other allocation algorithms are used for filtering, such as: neighbor cell non-conflict and non-confusion, reuse distance, reuse layer number, modulo 3 unchanged, modulo 3 unequal, modulo 30 unchanged, modulo 30 unequal, correlation, etc.

[0079] The network management device assigns a new PCI and applies it to the network element devices. The network management device then applies the assigned new PCI to the network element devices, resolving the PCI conflict issue in the cell.

[0080] For the overall processing procedure of the above examples, please refer to [link / reference]. Figure 7 As shown, including but not limited to:

[0081] S701: The network element device discovers that the PCI of a cell is conflicting with that of another cell (confusion can be considered as one type of conflict), and the cell is designated as a cell to be optimized.

[0082] S702: Network element devices report cells to be optimized to network management devices.

[0083] S703: The network management device excludes PCIs from the PCI restricted list from the PCI list to be allocated.

[0084] S704: The network management device selects PCIs that conform to the allocation algorithm from the remaining PCIs in the list of PCIs to be allocated. One selection process is described in the following steps.

[0085] S705: The network management device selects a PCI that meets the multiplexing distance requirement from the remaining PCIs.

[0086] S706: The network management device selects the PCI that meets the multiplexing layer requirement from among the PCIs that meet the multiplexing distance requirement.

[0087] S707: The network management device selects a PCI that meets the modulo 3 requirement from among the PCIs that meet the multiplexing layer requirement.

[0088] S708: The network management device selects PCIs that satisfy modulo 3 and other correlation algorithms.

[0089] S709: The network management device selects a PCI from the PCIs that satisfy each allocation algorithm as the new PCI for the cell to be optimized.

[0090] S710: The network management device applies the new PCI to the network element device.

[0091] To facilitate understanding, this embodiment will be illustrated with several application scenarios below.

[0092] Application Scenario Example 1:

[0093] Please see Figure 8 As shown, including but not limited to:

[0094] S801: Set the PCI restricted list detection switch for the network element device to off.

[0095] S802: The network element device detected a PCI conflict between cell A (from this vendor) and cell B (from a different vendor).

[0096] S803: Network management device optimizes cell A; the available PCI list for cell A is {0,1,2,3}, and the PCI restricted list is empty.

[0097] S804: The PCI value assigned to cell A by the network management device is 2, which is the value in {0,1,2,3}.

[0098] S805: The network management device applies the newly assigned PCI value 2 to the network element device.

[0099] Application Scenario Example 2:

[0100] Please see Figure 9 As shown, including but not limited to:

[0101] S901: The network element device is set to enable the PCI restricted list detection switch for the cell.

[0102] S902: The network element device detects neighboring cells A1 (PCI 100), A2 (PCI 101), A3 (PCI 102), and A4 (PCI 103) of cell A (this vendor). Then the PCI restricted list of cell A is {100, 101, 102, 103}. In this example, this detection process is assumed to be real-time detection.

[0103] S903: The network element device detected a PCI conflict between cell A (from this vendor) and cell B (from a different vendor) (confusing it into one type of conflict).

[0104] S904: Network management device optimizes cell A; the available PCI list for cell A is {100,101,102,103,104}, the PCI restricted list is {100, 101,102,103}, and the PCI value allocated to cell A is 104.

[0105] S905: The network management device applies the newly assigned PCI value 104 to the network element device.

[0106] Application Scenario Example 3:

[0107] Please see Figure 10 As shown, including but not limited to:

[0108] S1001: The network element device is set to enable the PCI restricted list detection switch for the cell.

[0109] S1002: The network element device detects neighboring cells A1 (PCI 100), A2 (PCI 101), A3 (PCI 102), and A4 (PCI 103) of cell A (this vendor). Therefore, the PCI restricted list of cell A is {100, 101, 102, 103}.

[0110] S1003: When the timer for the network element device cycle expires and it is detected that A1 is no longer a neighboring cell of cell A, the restricted list is updated to {101,102,103}.

[0111] S1004: The network element device detected a PCI conflict between cell A (from this vendor) and cell B (from a different vendor).

[0112] S1005: Network element device and network management device optimize cell A; the available PCI list for cell A is {100,101,102,103,104}, and the PCI restricted list is {101,102,103}; the PCI value allocated to cell A is 100 from {100,104}.

[0113] S1006: The network management device applies the newly assigned PCI value of 100 to the network element device.

[0114] Application Scenario Example 4:

[0115] Please see Figure 11 As shown, including but not limited to:

[0116] S1101: The network element device is set to enable the PCI restricted list detection switch for the cell.

[0117] S1102: The network element device detects neighboring cells A1 (PCI 100), A2 (PCI 101), A3 (PCI 102), and A4 (PCI 103) of cell A (this vendor). Then the PCI restricted list of cell A is {100, 101, 102, 103}.

[0118] S1103: Manually modify the PCI restricted list to {101,103,105}.

[0119] S1104: The network element device detected PCI confusion between cell A (this vendor) and cell B (different vendor).

[0120] S1105: Network management equipment optimizes cell A. The available PCI list for cell A is {100,101,102,103,104}, and the restricted list is {101,103,105}; the PCI value allocated to the cell is 102 from {100,102,104}.

[0121] S1006: The network management device applies the newly assigned PCI value 102 to the network element device.

[0122] In the examples above of this embodiment, in cross-network management scenarios, when performing PCI self-optimization of a cell, the network management device, unable to obtain neighboring cell information outside its jurisdiction, may assign a new PCI to the cell using a neighboring cell outside its jurisdiction. This can lead to new conflicts or confusion between the newly assigned PCI and the neighboring cell outside the network management device's jurisdiction after the new PCI takes effect, thus initiating another PCI self-optimization process. PCI changes cause cell restarts, which in turn increase call drop rates and lead to user access failures. This embodiment, however, maintains a restricted PCI list for the cell. This list includes PCIs both within and outside the network management device's jurisdiction. This restricted PCI list can be maintained through methods such as automatic maintenance by network element detection or manual intervention. When a PCI conflict occurs in the cell, the network management device does not use PCIs from the restricted PCI list for allocation during PCI self-optimization. This prevents new PCI conflicts from occurring, reducing call drop rates and improving network performance and resource utilization.
