The embodiment of the application provides a node replacement method and device, computer equipment and a storage medium, and aims to solve the technical problem that in the prior art, the SN replacement has low success rate, so that the SN replacement efficiency is low. The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that, in the node replacing method provided in the present application, the execution main body in fig. 2 to fig. 5 is a first standard base station, where the execution main body may also be a node replacing device, where the device may be implemented as part or all of the first standard base station by software, hardware, or a combination of software and hardware.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
In an embodiment, fig. 2 provides a node replacement method, where the embodiment relates to a first standard base station generating a candidate cell list according to a measurement report reported by a terminal, and determining a target replacement node according to the candidate cell list and a non-independent networking X2 interface control signaling, so as to complete a specific process of node replacement, and as shown in fig. 2, the method includes:
s101, a first standard base station receives a measurement report reported by a terminal and generates a candidate cell list according to the measurement report and a preset sorting rule; the measurement report is generated by the terminal according to the measurement configuration issued by the base station of the first standard.
In this embodiment, the first-system base station represents a base station of a current serving cell of a terminal, for example, under an EN-DC (E-UTRA & NR-Dual Connectivity, Dual Connectivity between a 4G radio access network and a 5G new access network) architecture, the 4G base station serves as an MN (Master Node, and the 5G base station serves as an SN (Secondary Node, Secondary Node), the first-system base station represents an SN under the EN-DC architecture, and the second-system base station referred to later represents an MN under the EN-DC architecture. The measurement report in this embodiment is a report generated by the terminal according to the measurement configuration issued by the base station of the first standard, for example, a User Equipment (UE) may simultaneously receive and transmit data with the MN and the SN under the EN-DC architecture, and since the UE has mobility, the coverage of the SN may be shifted out when the UE moves all the time, and at this time, if an SN node needs to be replaced for the UE, the current SN is required to issue the measurement configuration to the UE, and the signal quality of other SN cells is detected. The measurement configuration defines a plurality of frequency points to be measured, a measurement quantity to be measured, a measurement trigger quantity, a measurement report quantity and the like, wherein a plurality of cells under the same frequency point are measured. In this embodiment, the candidate cell list indicates a list of cells corresponding to SN nodes satisfying the replacement condition, and the preset ordering rule is an ordering of priorities of all SN nodes satisfying the replacement condition, that is, each cell in the candidate cell list is ordered according to a preset ordering rule from strong to weak signal strengths.
Illustratively, in practical applications. When detecting the signal quality of each cell, starting detection according to a measurement trigger quantity defined in the measurement configuration, when detecting that the measurement report quantity reaches a preset limit value, generating a corresponding measurement report and reporting the measurement report to the first-system base station, and after receiving the measurement report, the first-system base station generates a candidate cell list according to cell information carried in the measurement report and a preset sequencing rule.
S102, the first standard base station determines a target replacement node according to a candidate cell list and a non-independent networking X2 interface control signaling; and the control signaling of the non-independent networking X2 interface carries the neighbor cell information of the base station of the second standard.
In this step, the non-independent networking X2 interface indicates ENDC _ X2, which is a signaling sent by an MN (base station of a second standard) to an SN (base station of a first standard) through an X2 interface, where the signaling carries related information of an MN neighbor, that is, which NR nodes are MN neighbors are included in the field, it can be understood that the signaling needs to exist in the present application in practical application, where the name of the signaling may be a name of another form, and this embodiment does not limit this, as long as the signaling carries MN neighbor information. In this step, the target replacement node indicates the SN node to be replaced which is finally determined. For example, based on the candidate cell list generated in the step S101, the base station of the first standard determines the target replacement node according to the candidate cell list and the non-independent networking X2 interface control signaling, where the determination method may be to screen out the target replacement node from the candidate cell list according to the related information of the MN neighboring cell in the non-independent networking X2 interface control signaling, or may be other methods, and this embodiment is not limited thereto.
S103, the first system base station sends a replacement request to the second system base station, and the replacement request comprises a target replacement node.
Based on the target replacement node determined in the step S102, the first system base station sends a replacement request to the second system base station, where the replacement request carries the target replacement node, and the replacement request indicates that the first system base station requests the second system base station to replace itself with the target replacement node for the terminal, so that the terminal can obtain better service.
In the node replacement method provided in this embodiment, the first-standard base station generates a candidate cell list according to a measurement report reported by the terminal and a preset sorting rule, determines a target replacement node according to the candidate cell list and a non-independent networking X2 interface control signaling sent by the second-standard base station, and then the second-standard base station may replace the target replacement node for the terminal. In the method, because the first standard base station is a target replacement node screened from the candidate cell list according to the non-independent networking X2 interface control signaling, the adjacent cell information of the second standard base station in the non-independent networking X2 interface control signaling can enable the first standard base station to judge and screen the target replacement node more accurately and effectively, the replacement power of the node is improved, and the cost of the X2 interface signaling is reduced, the invalid node replacement is avoided, and the efficiency of successfully replacing the node is greatly improved.
On the basis of the foregoing embodiment, an embodiment of the present application further provides a node replacement method, which relates to a specific process in which a base station of a first standard determines a target replacement node according to a non-independent network X2 interface control signaling and a candidate cell list, as shown in fig. 3, where the step S102 includes:
s201, the first standard base station obtains the adjacent area information field of the second standard base station from the control signaling of the non-independent networking X2 interface.
In this step, the first-standard base station acquires the neighbor information field of the second-standard base station from the non-independent networking X2 interface control signaling, for example, in practical application, that is, the SN node acquires the NR neighbor information field information from the endec _ X2_ Setup signaling, where the field includes which NR nodes are MN neighbors.
S202, according to the information field of the adjacent cell of the second system base station, whether each cell in the candidate cell list is the adjacent cell of the second system base station is judged in sequence.
Based on the information field of the neighboring cell of the second-standard base station obtained in the step S201, the first-standard base station sequentially determines whether each cell in the candidate cell list is a neighboring cell of the second-standard base station, that is, each cell in the candidate cell list is sorted from strong to weak according to signal quality, the first-standard base station sequentially determines whether each cell is a neighboring cell of the second-standard base station from the first in the candidate cell list according to the order, and the determination basis is the information field of the neighboring cell of the second-standard base station in the non-independent network X2 interface control signaling.
S203, the first standard base station corresponding to the first cell is determined as a target replacement node, and the first cell is the cell of the adjacent cell of the second standard base station determined as the first cell.
Based on the judgment of each cell in the candidate cell list in the step S202, the first standard base station determines the first standard base station corresponding to the first cell as the target replacement node, where the first cell is a cell of which the first cell is determined as the neighboring cell of the second standard base station. The target replacement node needs to satisfy two conditions, one is that the cell corresponding to the node is a neighbor cell of the MN (base station of the second standard), and the other is that the signal quality of the cell corresponding to the node needs to be better relative to the terminal, so when the target replacement node is determined, the SN (base station of the first standard) corresponding to the cell in which the first candidate cell list is determined as the neighbor cell of the MN needs to be determined as the target replacement node.
In the node replacement method provided in this embodiment, a first cell that is a neighboring cell of a base station of a second standard is determined from a candidate cell list according to a neighboring cell information field of the base station of the second standard in a control signaling of an X2 interface of a non-independent network, and a base station of a first standard corresponding to the first cell is determined as a target replacement node, so that it can be ensured that the determined target replacement cell is not only a neighboring cell of the base station of the second standard, but also a base station of the first standard that can provide a cell with better signal quality for a terminal, and a success rate of node replacement is greatly increased.
In the following, a preset priority rule and a process of determining a candidate cell list according to the priority rule are described in detail through several embodiments, and in one embodiment, the present application further provides a node replacement method, which relates to a specific process of generating a candidate cell list according to a measurement report by a base station of a first standard, as shown in fig. 4, where the step S101 includes:
s301, the first standard base station acquires cell information of all adjacent cells from the measurement report to generate a measurement cell list.
In this embodiment, when the terminal detects the signal quality of the neighboring cells, if the report amount defined in the measurement configuration reaches the threshold, a measurement report is generated from data of the signal quality of all the cells that have been detected currently, and the measurement report is reported to the first-standard base station, so the measurement report received by the first-standard base station includes cell information of a plurality of neighboring cells, where the neighboring cells represent neighboring cells of a current serving cell of the terminal, which are all cells of the first-standard base station, that is, the cells in the candidate cell list in this embodiment all refer to the cells of the first-standard base station. For example, the base station of the first standard lists all cells carried in the measurement report into a measurement cell list, where the measurement cell list includes cell identifiers, cell signal quality, and other relevant parameters, which is not limited in this embodiment.
S302, the first standard base station sorts all cells in the measured cell list according to a preset sorting rule to obtain a candidate cell list.
Based on the measured cell list obtained in step S301, in this step, the first standard base station ranks all cells in the measured cell list so as to generate a candidate cell list, where the ranking is performed according to a preset ranking rule. In this embodiment, the cells involved in all measurement reports are sorted to generate the candidate cell list, so that all cells that may become the cells corresponding to the target replacement node are considered, and the signal quality of the cells in the candidate cell list is sorted from strong to weak.
Optionally, in an embodiment, an implementation manner is provided that the base station of the first standard sorts all cells in the measured cell list according to a preset sorting rule, and as shown in fig. 5, the S302 includes:
s401, the base station of the first standard acquires all measurement quantities from the measurement report.
When the terminal detects the signal quality of the neighboring cell, the terminal measures each measurement quantity defined in the measurement configuration, and the terminal reports the measurement report to the first standard base station, and the measured corresponding measurement quantity of each cell is carried in the measurement report.
S402, the first standard base station sorts all cells in the measured cell list according to the sorting priority of each measured quantity; the measurement quantity sorting priority is obtained from a preset sorting rule.
Based on all the measurement quantities obtained in the step S401, the first standard base station obtains the ranking priority of each measurement quantity from the preset ranking rule, and ranks all the cells in the measurement cell list according to the ranking priority of each measurement quantity. The ranking method provided in this embodiment specifically ranks the cells according to the priorities of the measurement quantities, and refines consideration of ranking, so that the accuracy of the cell signal strength in the generated candidate cell list is improved.
Since the measurement quantity includes more than one type, different trigger report quantities can be defined according to actual conditions in the measurement configuration, and for different trigger report quantities, the corresponding sorting priorities are different, and in one embodiment, different measurement quantities correspond to different sorting priorities when being used as trigger report quantities. Optionally, if the measurement quantity includes reference signal received power, reference signal received quality, and signal-to-noise ratio; when different measurement quantities are used as trigger reporting quantities, three sorting schemes are included corresponding to different sorting priorities, specifically:
scheme A: if the reference signal receiving power is used as the trigger reporting quantity, the sequencing priority is as follows: sorting the reference signal receiving power from high to low, wherein the same reference signal receiving power is sorted in front according to the higher reference signal receiving quality, and the same reference signal receiving power and the same reference signal receiving quality are sorted in front according to the higher signal-to-noise ratio;
scheme B: if the reference signal receiving quality is taken as the trigger reporting quantity, the sequencing priority is as follows: sorting the reference signal receiving quality from large to small, sorting the same reference signal receiving quality in front according to the larger reference signal receiving power, and sorting the same reference signal receiving power and the reference signal receiving quality in front according to the larger signal-to-noise ratio;
scheme C: if the signal-to-noise ratio is used as the trigger reporting quantity, the sequencing priority is as follows: and sorting the signals to noise ratios from large to small, wherein the sorting of the same signal to noise ratio is arranged in front of the sorting of the larger reference signal receiving power, and the sorting of the same signal to noise ratio and the larger reference signal receiving power is arranged in front of the sorting of the larger reference signal receiving quality.
Wherein, Reference Signal Receiving Power (RSRP) represents one of the key parameters that can represent the wireless Signal strength in the LTE network and the physical layer measurement requirement, and is the average value of the received Signal Power on all REs (resource elements) carrying Reference signals within a certain symbol; reference Signal Receiving Quality (RSRQ) represents LTE Reference Signal Receiving Quality, and is mainly used to rank different LTE candidate cells according to Signal Quality, and is used as an input for handover and cell reselection decision; the signal-to-Noise Ratio (SINR) represents the Ratio of the received strength of the desired signal to the received strength of the interfering signal (Noise and Interference).
In the scheme A, if the RSRP is used as the trigger report quantity, the basic rule of the sorting is that the RSRP values are sorted from large to small, the sorting of the same RSRP value is arranged in front of the larger RSRQ value, and the sorting of the same RSRP and the RSRQ value is arranged in front of the larger SINR value; in the scheme B, if the RSRQ is used as the trigger report quantity, the basic rule of the sorting is that the RSRQ values are sorted from large to small, the sorting of the same RSRQ value is arranged in front of the larger RSRP value, and the sorting of the same RSRQ and the RSRQ values is arranged in front of the larger SINR value; in the scheme C, if SINR is used as the trigger report, the basic rule of sorting is to sort according to SINR values from large to small, sort with the same SINR value according to the larger RSRP value, and sort with the same SINR and RSRP value according to the larger RSRQ value. Of course, the above description is only given by way of example for different sorting priorities in different situations, and if other sorting manners or other situations are involved in practical application, they may be determined according to practical situations, and this embodiment is not limited in this way.
In addition, in the measurement configuration sent by the base station of the first standard to the terminal, in order to ensure effective evaluation of the generated candidate cell ranking, in an embodiment, measurement trigger report amounts of different frequency points in the measurement configuration sent by the base station of the first standard are all the same. In another embodiment, the measurement configuration issued by the base station of the first standard is used to detect an A3/a5 event, and the configuration measurement includes frequency points of a plurality of base stations of the first standard.
When the measurement configuration is carried out, the configuration is the same for the measurement triggering quantity and the reporting quantity of different frequency points, so that the standards of all cells are the same when sequencing is carried out, and the sequencing accuracy can be ensured. When measurement configuration is performed, the base station of the first standard can define detection of an event A3/a5, wherein the event A3/a5 is an event specified in LTE, that is, A3 indicates that the quality of an adjacent cell is higher than that of a serving cell, and when the event meeting the condition is reported, the source base station starts a handover request; the a5 event indicates that the serving cell quality is below a certain threshold and the neighbor cell quality is above a certain threshold. The measurement report reported by the terminal is a measurement report of an A3/a5 event, wherein multiple frequency points including co-frequency and inter-frequency cells can be configured and measured in the measurement of an A3/a5 event, and therefore, multiple cells under multiple frequency points are included in the measurement report of the received A3/a5 event.
To the implementation process of the complete scheme of the present application, three major modules can be divided, which include an SN replacement decision module, an SN replacement processing module, and an SN replacement implementation module, wherein the SN replacement decision module: the main responsibility is to send the measurement configuration to the UE; and collecting a measurement report of the UE and triggering SN replacement. SN replacement processing module: the main responsibility is to screen the replaceable optimal target cell from the cells of the measurement report according to the NR neighbor Information field Information in the endec _ X2_ Setup signaling. SN replacement execution module: the main responsibility is to send a SN change request to the MN to perform SN change.
