Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a terminal user secondary cell configuration method, a terminal user secondary cell configuration apparatus, an electronic device, and a computer-readable medium.

Background

When the cell traffic is large, carrier aggregation is triggered. The concept of Carrier Aggregation (CA) is first introduced in LTE (Long Term Evolution, Long Term Evolution technology) R10, that is, by aggregating a plurality of Carrier units together for use, the system bandwidth and the network capacity are effectively increased, so that a terminal can access a plurality of carriers and perform uplink and downlink data transmission on the plurality of Carrier units at the same time. With the wide implementation of the 5G technology, the 5G terminal supports a 5G NR (New Radio, New air interface) and carrier aggregation technology. Such a terminal may be connected to a Primary Cell (PCell) and a plurality of Secondary cells (scells), so that the terminal has more network resources.

In the prior art, after receiving measurement configuration information of a network side, all terminals in a carrier aggregation cell directly initiate related measurement, and interaction of air interface signaling between the terminals and the network side is increased.

In the auxiliary cell configuration method for a terminal user according to the exemplary embodiment of the present disclosure, by dividing terminal users in a cell range into a plurality of terminal user sets, when any one terminal user in the terminal user sets triggers an auxiliary cell configuration event, an auxiliary cell quality measurement request is issued only to one measurement terminal user in the terminal user sets, then a target auxiliary cell is determined from a plurality of candidate auxiliary cells according to an auxiliary cell quality measurement report returned by the measurement terminal user, and auxiliary cell configuration is performed on all terminal users in the terminal user sets according to the target auxiliary cell. The auxiliary cell configuration method of the terminal user in the disclosed example embodiment is suitable for the conditions of auxiliary cell addition and change in a carrier aggregation scene, on one hand, the interaction process of all terminals and a base station can be simplified into the interaction process of part of terminals and the base station by dividing the terminal user into a plurality of terminal user sets and measuring the interaction between the terminal user and the base station through one measuring terminal user in the set, the service experience is not influenced, and the signaling interaction between the terminals and the base station is reduced by greatly reducing the number of the terminals interacting with the base station, so that the power consumption in the interaction process of the terminals and the base station is reduced, and meanwhile, the power consumption of the base station can be reduced, and the purpose of saving energy is achieved; on the other hand, the base station purposefully configures proper auxiliary cells for all the terminals according to the auxiliary cell quality measurement report reported by the measurement terminal user, so that the energy consumption caused by the base station trying all the candidate auxiliary cells in sequence can be avoided, and the pertinence is strong.

The above steps of the present exemplary embodiment will be described in more detail with reference to fig. 2 to 4. The 5G terminals related to the patent all have a carrier aggregation function and the function switches are opened.

In step S110, the terminal users in the cell area are divided into a plurality of terminal user sets according to the location information and the signal receiving power of each terminal user in the cell area of the primary cell.

In this exemplary embodiment, the base station may extract the location information of the end user through an SRS (Sounding Reference Signal). In the NR or LTE system, PRS (Positioning Reference Signal) for Positioning in downlink and SRS (sounding Reference Signal) for Positioning in uplink are defined, and may be used for Positioning measurement for a mobile terminal within the coverage of a base station.

The Signal received Power of an end user refers to the RSRP (Reference Signal Receiving Power) of the end user, which is a linear average of received Power over resource elements carrying Reference signals over a measurement frequency bandwidth and can be used to measure the cell Signal quality.

In this exemplary embodiment, a clustering algorithm module may be added at the base station side, and the clustering algorithm module may divide the terminal users into a plurality of terminal user sets according to the location information and the signal receiving power of each terminal user within the cell range.

In this exemplary embodiment, as shown in fig. 2, dividing the terminal users in the cell range into a plurality of terminal user sets according to the location information and the signal receiving power of each terminal user in the cell range of the primary cell may specifically include the following steps:

step S210, taking a plurality of terminal users in the cell range of the main cell as an initial cluster center, and dividing all terminal users in the cell range into a plurality of initial terminal user sets according to the position information of other terminal users in the cell range.

Firstly, a base station side clustering algorithm module randomly selects a plurality of terminal users in a cell range as an initial cluster center, and for the rest terminal users, all the terminal users in the cell range can be divided into a plurality of initial terminal user sets according to the position information of other terminal users in the cell range.

In this exemplary embodiment, as shown in fig. 3, dividing all terminal users in a cell range into a plurality of initial terminal user sets according to location information of other terminal users in the cell range may specifically include the following steps:

and S310, determining the distance between the other terminal users and the initial cluster center according to the position information of the other terminal users in the cell range.

According to the position information of other terminal users in the cell range and the position information of each initial cluster center, the distance between the other terminal users in the cell range and each initial cluster center can be determined.

And S320, dividing all terminal users in the cell range into a plurality of initial terminal user sets according to the distances between other terminal users and the initial cluster center.

And assigning other terminal users to the initial cluster center closest to the initial cluster center according to the distance between the other terminal users and the initial cluster center, thereby dividing all terminal users in the cell range into a plurality of initial terminal user sets.

S220, according to the position information and the signal receiving power of each terminal user, a plurality of cluster centers in a cell range are updated in an iterative mode on the basis of an initial terminal user set, and a plurality of terminal user sets in the cell range are obtained.

In this exemplary embodiment, as shown in fig. 4, according to the location information and the signal received power of each terminal user, performing iterative update on multiple cluster centers in a cell range on the basis of an initial terminal user set to obtain multiple terminal user sets in the cell range, which may specifically include the following steps:

and S410, obtaining the average signal receiving power corresponding to each terminal user set according to the signal receiving power of the terminal user in each terminal user set of the previous iteration.

According to the RSRP of each terminal user in each terminal user set in the previous iteration round, the RSRP average value corresponding to each terminal user set can be obtained through calculation.

And S420, determining a target terminal user in each terminal user set according to the average signal receiving power corresponding to each terminal user set.

And then, taking the terminal user with the RSRP value in the terminal user set closest to the RSRP average value corresponding to the terminal user set as the target terminal user in the current iteration turn.

And S430, judging whether the distance between the cluster center and the target terminal user is greater than or equal to the updating distance threshold value or not according to the cluster center of the terminal user set and the position information of the target terminal user.

And judging whether the distance between the cluster center of the previous iteration and the current redetermined target terminal user is larger than or equal to the updating distance threshold value.

And S440, if the distance between the cluster center and the target terminal user is greater than or equal to the updating distance threshold, updating the target terminal user to the cluster center corresponding to the current iteration turn.

And if the distance between the cluster center of the previous iteration round and the current re-determined target terminal user is greater than or equal to the updating distance threshold, determining the target terminal user as a new cluster center corresponding to the current iteration round.

And S450, if the distance between the cluster center and the target terminal user is smaller than the updating distance threshold, continuing to take the cluster center of the terminal user set in the previous iteration round as the cluster center corresponding to the current iteration round.

And if the distance between the cluster center of the previous iteration round and the current redetermined target terminal user is smaller than the updating distance threshold, the cluster center does not need to be updated, and the cluster center of the previous iteration round is continuously used.

And S460, subdividing the terminal user set in the cell range according to the cluster center corresponding to the current iteration turn until all the cluster centers are not changed any more, and stopping iteration.

And finally, according to the cluster center corresponding to the current iteration round and the position information of other terminal users, re-dividing the terminal user set in the cell range, and continuously repeating the process until all the cluster centers are not changed any more, so that the terminal users are divided into a plurality of clusters, and each cluster has respective characteristics.

In the present exemplary embodiment, in consideration of the problem of mobility of the terminal users, each cluster may be periodically updated, that is, re-clustering is performed once every a period of time, and each terminal user set in the cell range is re-divided according to a preset time interval.

In addition, other methods may be used to divide the terminal users within the cell, and the clustering algorithm is only used as an example in the present exemplary embodiment, and is not particularly limited.

In step S120, when any one of the end users in the end user set triggers the secondary cell configuration event, the measurement end user in the end user set is determined, and a secondary cell quality measurement request is sent to the measurement end user.

In this example embodiment, the secondary cell configuration event may include a secondary cell addition event and a secondary cell change event. When a neighbor cell is better than an absolute threshold, the a4 event, i.e., the secondary cell addition event, is triggered. When the service quality of the neighboring cell is better than that of the current secondary cell, an A6 event, namely a secondary cell change event, is triggered.

In the prior art, when an end user triggers an a4 event, a nodeb (5G base station) issues an a4 measurement to all terminals in a cell, and the nodeb attempts to configure a secondary cell in sequence from high to low according to RSRP signal quality of candidate scells in an a4 measurement report. When a terminal user triggers an a6 event, the nodeb issues an a6 measurement to all terminals in the cell, and the nodeb determines which neighboring cell replaces the original secondary cell to become a new secondary cell according to the RSRP signal quality of the SCell in the a6 measurement report.

However, in the present exemplary embodiment, when any one end user in a certain end user set triggers an a4 or a6 event, that is, a situation related to the addition or change of the secondary cell (the base station only adds or changes the secondary cell for the terminal through the a4/a6 event, but does not require the terminal to perform handover), it is determined that all terminals in the end user set are related to the problem. At this time, one of all the end users triggering the a4 or a6 event in the end user set may be arbitrarily selected as the measurement end user, the base station issues a4 or a6 measurement request only to the measurement end user, and the measurement end user feeds back a measurement report to the base station.

In step S130, a secondary cell quality measurement report returned by the measurement terminal user is obtained, and a target secondary cell is determined from the plurality of candidate secondary cells according to the secondary cell quality measurement report.

In this exemplary embodiment, after receiving the secondary cell quality measurement report returned by the measurement terminal user, the base station may select a most suitable cell from the candidate secondary cells reported by the measurement terminal user as a target secondary cell according to the RSRP average capability in the terminal user set, where the RSRP signal quality of the target secondary cell is higher than the RSRP average capability in the terminal user set and higher than the RSRP average capability of the terminal user in the cell range.

In step S140, secondary cell configuration is performed on all terminal users in the terminal user set according to the target secondary cell.

And finally, the base station performs secondary cell configuration on all terminal users in the terminal user set according to the target secondary cell, wherein the configuration comprises the addition and the change of the secondary cell. For the secondary cell addition event, after the target secondary cell is determined, the target secondary cell may be added to all terminal users in the terminal user set. For the secondary cell change event, after the target secondary cell is determined, the original secondary cells of all terminal users in the terminal user set can be replaced by the target secondary cell. Compared with a method that the base station tries to configure the secondary cell in sequence from high to low according to the RSRP signal quality, the method is more targeted and has simpler steps.

In this exemplary embodiment, an energy saving method in a carrier aggregation scenario is provided by combining flows and characteristics of carrier aggregation secondary cell configuration and change, and a network side positioning technology, where a base station side counts location information and RSRP of terminal users in a carrier aggregation cell through a clustering algorithm, and terminal users with the same or close location information and RSRP are clustered into a class by using the positioning technology and the clustering algorithm, and if there is a problem in the class of terminals that relates to secondary cell addition or change, other terminals of the class also relate to the class, and a target secondary cell to be added or changed is also the same. Thus, if an event of a4 or a6 triggers, the base station may issue a4 or a6 measurement to any terminal of the class only, and the terminal feeds back a measurement report, and the base station adds or changes secondary cells to all terminals of the class according to the measurement report fed back by the terminal.

Fig. 5 is a schematic flow chart of adding a secondary cell to an end user in an embodiment of the present disclosure, which is an illustration of the above steps in this exemplary embodiment. When the cell traffic is large, carrier aggregation is triggered, and the specific steps of the flowchart at this time are as follows:

and step S510, the base station extracts the position information of the terminal user through the SRS.

And S520, clustering the terminal users in the cell by the base station through a clustering algorithm.

And clustering the terminals in the cell by using a clustering algorithm based on division, namely randomly selecting a plurality of terminals as the center of each cluster, assigning the centers to the nearest clusters to the rest terminals according to the distance between the terminals and the centers of the clusters, recalculating the RSRP average value of each cluster, updating the RSRP average value to be a new cluster center, and continuously repeating the process, so that the terminals in the cell are divided into a plurality of clusters, wherein each cluster has respective characteristics. The clusters of each cluster may be updated periodically, i.e., re-clustered at intervals, to account for mobility issues.

Step s530.a4 event occurs.

An a4 event occurs in a certain terminal a in a certain cluster (the a4 event only represents that the base station adds a secondary cell to the terminal only through the a4 event, but does not require the terminal to perform handover), that is, the current neighbor cell of the terminal a is better than an absolute threshold.

And S540, the base station issues A4 measurement to a certain end user in the cluster.

The gNodeB (5G base station) sends A4 measurement to the terminal A only, so that the terminal A measures the RSRP of the surrounding adjacent regions.

And S550, the terminal user carries out measurement.

And step S560, the terminal user feeds back a measurement report to the base station.

Terminal a feeds back a measurement report to the gbnodeb.

And S570, adding the auxiliary cells to all the terminal users in the cluster by the base station according to the measurement report.

After receiving the measurement report fed back by the terminal a, the gnnodeb may select the most suitable cell from the candidate cells reported by the terminal a according to the RSRP average capability in the cluster, and perform secondary cell configuration for all terminals in the cluster. Other clusters in the cell do the same if this is the case.

As shown in fig. 6, which is a schematic flowchart of a secondary cell change performed on a terminal user in an embodiment of the present disclosure, on the basis of completing the secondary cell addition, specific steps of the flowchart are as follows:

and S610, adding the secondary cell.

And S620, keeping the existing clustering result and periodically updating.

Step s630.a6 event occurs.

When a terminal a in a cluster has an a6 event (the a6 event only represents that the base station changes the terminal to the secondary cell only through the a6 event, but does not require the terminal to perform handover), that is, when the neighboring cell service quality of the terminal a is better than the secondary cell service quality.

And step 640, the base station issues A6 measurement to a certain end user in the cluster.

The gNodeB only sends A6 measurement to the terminal A, so that the terminal A can measure the RSRP of the surrounding neighbor cells.

Step S650, the terminal user carries out measurement.

And S660, the terminal user feeds back a measurement report to the base station.

Terminal a feeds back a measurement report to the gbnodeb.

And S670, the base station changes the auxiliary cells for all the terminal users in the cluster according to the measurement report.

After receiving the measurement report fed back by the terminal a, the gNodeB may select the most suitable cell among the candidate cells reported by the terminal a according to the RSRP average capability in the cluster, to perform secondary cell change for all terminals in the cluster. Other clusters in the cell do the same if this is the case.

It should be noted that although the steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that the steps must be performed in this particular order or that all of the depicted steps must be performed to achieve desirable results.
