Description

Technical Field

[0001] The present application belongs to the field of communications, and in particular, relates to a method, device, equipment and storage medium for RNA distribution. Background Art

[0002] The fifth generation of mobile communication technology 5G network needs to connect everything, especially in the massive machine type communication (mMTC) scenario, which requires connecting a large number of low-power devices. On the one hand, these devices need to minimize signaling interaction with the 5G network to save power, and on the other hand, they need to quickly access and reduce latency when data is sent to the network or the network sends data to the device.

[0003] For this purpose, the RRC_INACTIVE state of the device is defined in the 3rd Generation Partnership Project 3GPP specification. In this state, the device is in a state similar to the "sleep" state of a computer on the wireless side, but it is still connected from the core network side. The 5G base station will be configured with a radio access network notification area (RAN-Based Notification Area, RNA), which is composed of several cells. When the user equipment UE moves between RNAs, it does not need to report its location changes to the 5G base station, but only needs to send periodic RNA update messages. When it moves out of the RNA, it will also initiate the RNA update process and re-report the location changes. When there is signaling or data sent to the device on the network side, the 5G base station will page it in the cell corresponding to the RNA and can send XnAP RAN paging to the adjacent gNB (if the RNA includes the cell of the adjacent gNB) to "wake up" the device and receive data. In this way, the purpose of power saving and access and reducing latency is achieved.

[0004] When configuring RNA, existing methods, in addition to manual static configuration, usually configure RNA based on auxiliary information reported by the device to the base station or configure RNA based on other base station and 5G core network information obtained by the base station. The reporting of auxiliary information and the acquisition of other base station and 5G core network information increase the network resource overhead of the device and the base station.

[0058] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0060] RNA is usually composed of a 5G base station gNB providing a clear cell list as RNA to the user equipment UE, or a gNB providing a 5G radio access network area identifier RAN area ID list as RNA to the UE. The RAN area provided here is a subset of the core network tracking area CN Tracking Area or is equal to the CN Tracking Area. One RAN area corresponds to a RAN area ID, and a RAN area consists of a tracking area identifier TAI and an optional 5G radio access network area code RANArea Code. A cell will broadcast its RAN area ID in its system message. The UE determines whether it is within the RNA range and whether it needs to report the location change to the 5G base station based on the RNA configuration provided by the gNB.

[0061] When configuring RNA, in addition to manual static configuration, the existing solutions include setting a threshold through the device, reporting auxiliary information when the threshold is reached or exceeded, and the base station receives the auxiliary information and then decides whether to update the RNA; the other is that the base station updates the configured RNA by obtaining information from other base stations and the 5G core network AMF.

[0062] For the method of updating RNA by having the device report auxiliary information, when the device is in the RRC_INACTIVE state, if the device needs to report auxiliary information, the device itself is required to have a strong measurement function. However, the measurement of the device and the reporting of auxiliary information require the consumption of the computing power and electric energy of the device, and the purpose of power saving cannot be achieved. At the same time, it also increases the overhead of network resources between the device and the base station.

[0063] Regarding the method in which the base station obtains information from other base stations and the 5G core network AMF to update the configuration RNA, the base station frequently exchanges information with other base stations and the 5G core network AMF, which will also increase the network overhead. Moreover, for some devices with weak mobility, it is impossible to better plan the RNA within the base station range.

[0064] In order to solve the problems of the prior art, the embodiments of the present application provide a method, apparatus, device and storage medium for RNA distribution. The embodiments of the present application record and analyze the activity status of the device, the time and continuity of the residence in the cell, and summarize and calculate the different activity dimensions and elements of the device through a specific algorithm to find the most likely activity area of ​​the device, and quickly and dynamically configure the best RNA for the device, thereby achieving the purpose of saving device power and reducing the network resource overhead of the device and the base station. The following first introduces the method for RNA distribution provided by the embodiments of the present application.

[0065] Figure 1 The flowchart of the method for RNA distribution provided by an embodiment of the present application is shown. The method is applied to a base station. When the base station executes the method, the cache data obtained and generated by the method is transmitted to the 5G core network AMF through the N2 port connection, such as Figure 1 As shown, the method may include the following steps:

[0066] S110, obtaining the residence information of the target device in each cell of the base station.

[0067] The target device is connected to the base station in communication, and the base station can directly obtain the residency information of the target device in each cell of the base station.

[0068] The embodiment of the present application uses the residence information of the target device in each cell of the base station as the data source to distribute RNA. Since the residence information of the target device in each cell of the base station is highly correlated with the communication activity of the cell, RNA can be accurately distributed based on the residence information of the target device in each cell of the base station.

[0069] S120, when receiving a RNA update request notified by the radio access network of the target device, obtaining the cell where the target device was last located.

[0070] S130, comparing the cell where the target device was last located with the preset RNA to obtain a position comparison result.

[0071] The embodiment of the present application can roughly determine the location of the target terminal by comparing the cell where the target device was last located with the preset RNA.

[0072] In one embodiment, the predetermined RNA may include:

[0073] The first cell where the target device is located when it first enters the coverage of the base station; or, the first cell, and a neighboring cell adjacent to the first cell.

[0074] S140, updating the residence information of the target device in each cell of the base station according to the position comparison result to obtain updated residence information.

[0075] In one embodiment, the resident information is Figure 2 As shown, it may include: residence time Du, which represents the total residence time of the target device in the cell; the last residence time T, which represents the time when the target device recently initiated RNA update in the cell, which can reflect the activity level of the target device in the cell; the number of consecutive residence times C, when the target device moves from other cells to this cell, this value +1 can represent the number of times the target device moves into this cell; S140 may include:

[0076] When the position comparison result indicates that the preset RNA includes the cell where the target device was last located, the residence time and the last residence time of the target device in the cell included in the preset RNA are updated to obtain updated residence information.

[0077] When the position comparison result indicates that the preset RNA includes the cell where the target device was last located, it means that the target device may move in the preset RNA, so the residence time and the last residence time of the target device in the cell included in the preset RNA are updated.

[0078] When the position comparison result indicates that the preset RNA does not include the cell where the target device was last located, the number of consecutive residency times of the target device in the cell included in the preset RNA is updated to obtain updated residency information.

[0079] When the position comparison result indicates that the preset RNA does not include the cell where the target device was last located, it means that the target device has left the preset RNA, and only the consecutive residence times of the target device in the cell included in the preset RNA are updated.

[0080] S150: Determine the target reachability distances between the cell where the target device is last located and other cells according to preset cell reachability distance information.

[0081] The preset cell accessibility distance information refers to an overhead distance of accessibility between two cells. The accessibility here includes but is not limited to the accessibility of wireless signals, geographical accessibility, etc., and is the comprehensive overhead value of these accessibility distances. For example, if two cells are adjacent but separated by a river, the accessibility distance is also considered to be greater than that of another adjacent cell without a river barrier, such as Figure 3 shown.

[0082] S160 , allocating a target RNA to the target device according to the updated residency information and the target reachability distance.

[0083] Update the residence information and target reachability distance as Figure 4 As shown, based on the updated residency information and the target reachability distance, the target RNA can be assigned to the target device.

[0084] The embodiment of the present application distributes RNA based on updated residence information and target reachability distance. Since updated residence information and target reachability distance are highly correlated with the communication activity of the cell, RNA can be accurately distributed based on the residence information of the target device in each cell of the base station.

[0085] In one embodiment, S160 may include:

[0086] S1601: Calculate the communication activity of each cell according to the updated resident information and the target reachability distance.

[0087] In one embodiment, S1601 may include:

[0088] The updated residence information and the target reachability distance are normalized to obtain a normalized result.

[0089] The updated dwell information includes the updated dwell time Du, the last dwell time T, and the number of consecutive dwell times C. The dwell time Du, the number of consecutive dwell times C, and the target reachability distance D are all positively correlated with the communication activity. The normalized processing result can be obtained by using the following formula, taking the dwell time Du as an example:

[0090]

[0091] in, represents the normalized result of the dwell time, Du i Represents any dwell time, and Max(Du) represents the maximum value of the dwell time.

[0092] For the last residence time T, first calculate the duration K from the last residence time to the current time. Since the smaller the K value, the more active the target device is recently, that is, K is negatively correlated with the communication activity, the normalized result of the last residence time T can be obtained using the following formula:

[0093]

[0094] Among them, K i Indicates the duration from any last stay time to the current time, and Max(K) indicates the maximum value of the duration from the last stay time to the current time.

[0095] An average value of the normalized processing results of each cell is calculated; and the average value is determined as the communication activity.

[0096] The embodiment of the present application uses the updated residence information and the target reachability distance as data sources, performs normalized average calculation, and uses the calculation result as the communication activity. Since the updated residence information and the target reachability distance are highly correlated with the communication activity level of the cell, the calculated communication activity conforms to the actual communication situation of the cell, and based on the normalized average calculation, the adverse effects of abnormal data on the communication activity of the cell are reduced, thereby further improving the accuracy of the communication activity.

[0097] In one embodiment, S1601 may further include:

[0098] S16011, normalize the updated residence information and the target reachability distance to obtain a normalized result.

[0099] Since the number of cells may be large, which will affect the calculation speed, a series of combined conditions can be pre-set to pre-eliminate the updated residence information and target reachability distance corresponding to the normalized processing results. For example, cells whose normalized value corresponding to the residence time is lower than a preset minimum threshold and whose consecutive residence times are lower than another preset minimum threshold can be considered as inactive cells of the target device, that is, the target device is very inactive in these cells and may never even move to these cells. In this way, the data corresponding to the cells will be eliminated, which can reduce the amount of calculation for screening.

[0100] S16012, calculating the weight values ​​of the updated residence information and the target reachability distance according to the normalization processing result.

[0101] In one embodiment, S16012 may include:

[0102] According to the normalized processing results, the harmonic mean of the updated residence information and the target reachability distance is calculated, and the harmonic mean M i It can be obtained by the following formula:

[0103]

[0104] W i represents the normalized processing result, and n represents the number of normalized processing results.

[0105] The weight values ​​of the updated residence information and the target reachability distance are calculated based on the normalized processing result and the harmonic mean value. The weight value p can be obtained by the following formula:

[0106]

[0107]

[0108] W i represents the normalized processing result, n represents the number of normalized processing results, M i Represents the harmonic mean.

[0109] S16013, calculating the expected value of the product of the normalized processing result and the weight value of each cell. The expected value E can be obtained by the following formula:

[0110]

[0111] Among them, W i represents the normalized result, p i Indicates the weight value.

[0112] S16014, determine the expected value as the communication activity.

[0113] S1602, sorting the communication activities in descending order, and allocating the cells corresponding to the preset number of communication activities before sorting and the cell where the target device was last located as target RNA to the target device.

[0114] The embodiment of the present application uses the updated residence information and the target reachability distance as data sources, performs weighted expectation calculation, and uses the weighted expectation result as the communication activity. Since the updated residence information and the target reachability distance are highly correlated with the communication activity level of the cell, the calculated communication activity conforms to the actual communication situation of the cell, and based on the weighted expectation calculation, the adverse effects of abnormal data on the communication activity of the cell are reduced, thereby further improving the accuracy of the communication activity.

[0115] like Figure 5 As shown, the embodiment of the present application shows a set of experimental data of communication activity. All cells are arranged from large to small according to the size of communication activity. The larger the communication activity, the more active the target device is in the cell. Figure 5 As shown, it can be seen that the target device is more active in CELL1 and CELL2 than in other cells. The target RNA region can be selected according to the configuration. For example, the first two cells are selected, and then the cell CELLx where the target device was last located is added, that is, (CELL1, CELL2, CELLx) is used as the new RNA region assigned to the device, that is, the target RNA region.

[0116] The RNA allocation method of the embodiment of the present application obtains the residence information of the target device in each cell of the base station without the need for the device to report any auxiliary information; when receiving an RNA update request notified by the wireless access network of the target device, the cell where the target device was last located is obtained, and the cell where the target device was last located is compared with the preset RNA to obtain a position comparison result; according to the position comparison result, the residence information of the target device in each cell of the base station is updated to obtain updated residence information, which is more in line with the communication activity behavior characteristics of the device; and taking into account the accessibility between cells, the target accessibility distance between the cell where the target device was last located and other cells is determined according to the preset cell accessibility distance information; the target RNA is allocated to the target device according to the updated residence information and the target accessibility distance; the device can be targetedly configured with RNA without the need for the device to report any auxiliary information, so that the network's paging of the device is more accurate, and does not occupy the network resource overhead of the device and the base station, which is conducive to the device saving more power.
