Wherein in the description of the present application, unless otherwise indicated, the meaning of "plurality of" is used.

The control method of the fresh air handling unit provided by the application will be described below with reference to the embodiments.

The inventive concepts of the present application can be summarized as follows: firstly, receiving a switching request message of a source cell, determining a coverage relation between a target cell and a neighboring cell, if the coverage relation is completely the same coverage, determining a configuration mode and a configuration time of a corresponding CA cell according to whether a candidate cell list is carried in the switching request message, whether a first state indication value of a blind configuration switch of a carrier aggregation CA cell is directly configured, whether a second state indication value of a traffic switch of the CA cell is reconfigured when traffic reaches a threshold, determining a configuration mode and the configuration time of the corresponding CA cell, and secondly, if the coverage relation is not completely the same coverage, determining the configuration mode and the configuration time of the corresponding CA cell according to whether the second state indication value of a traffic switch of the CA cell is reconfigured when the traffic reaches the threshold is carried in the switching request message, and finally, configuring the CA cell at the corresponding configuration time according to the determined configuration mode. Therefore, according to the configuration situation of the terminal at the base station of the switching source side and the target side, the embodiment of the application provides the configuration mode and the configuration time of the CA cell, ensures that the CA cell is configured under different application scenes, is not limited by whether the switching request necessarily carries the candidate cell list, and can realize the CA cell configuration in the switching request.

In the related art, the configuration method of carrier aggregation includes the following steps:

(1) The source cell selects the primary cell PCell and the candidate secondary cell SCell list, and the list is provided for the target cell in the preparation stage of switching to assist the target cell to select the SCell. The candidate SCell list contains cells with the largest RSRP (Reference Signal Receiving Power, reference signal received power) values on all the frequency points, wherein the contained content contains cell identification and measurement results.

(2) The target cell selects the PCell/SCell(s) according to the RSRP, admission and whether the cell supports CA and other information, and allows the target base station eNB to reselect the PCell.

(3) After receiving the MR (Measurement Report ) of the terminal, the RRC (Radio Resource Control ) sends the de-configured secondary cell message and the handover message to the terminal UE in one RRC reconfiguration message.

(4) For the requirement of carrying auxiliary cell addition in the handover message, when the target cell receives the handover request message of the source cell, if the target cell supports CA, according to the configured auxiliary cell configuration algorithm (i.e. based on strategy, based on equivalent SINR, based on absolute RSRP, etc.), if the auxiliary cell recommended by the source cell meets the condition, and FGI (Feature group indicators, function group index) of the UE indicates whether the handover message carries auxiliary cell addition information (SCell addition within the Handover to EUTRA procedure) bit is 1, the auxiliary cell addition information is carried in the handover command to the source cell. After receiving the handover command, the source cell carries SCellToAddModList and scelltorreleaslist-r 10 information in a handover message to notify the UE through RRC RRCConnectionReconfiguration.

(5) In addition, during the switching process, the UE saves the configuration information of the source PCell and the SCell, and performs deleting operation according to the switching instruction content. After the handover is completed, the SCell is in a deactivated state.

The method is a terminal mobility method aiming at carrier aggregation of LTE users, the implementation of LTE configures an auxiliary carrier in the terminal moving process, a source side limited by handover provides a candidate cell list of an auxiliary target cell selection Scell, and SCELL can be configured after a measurement threshold is met, and the original method has some limitations.

Based on the above description, the embodiments of the present application provide a configuration method for carrier aggregation, in a moving process of a terminal, according to a measurement threshold and a traffic threshold, for a cell coverage type condition of a target side after moving, a CA is flexibly configured and a CA is flexibly de-configured in the moving process of the terminal, and an overall flow chart is shown in fig. 1, and includes the following contents:

in step 101, a handover request message of a source cell is received, and a coverage relationship between a target cell and a neighboring cell for handover is determined.

In step 102, if the coverage relationship is completely the same coverage, determining the configuration mode and the configuration opportunity of the corresponding CA cell according to whether the handover request message carries the candidate cell list, whether the first status indication value of the blind configuration switch of the carrier aggregation CA cell is directly configured, and whether the second status indication value of the traffic switch of the CA cell is reconfigured when the traffic reaches the threshold.

In step 103, if the coverage relationship is not completely identical, determining the corresponding CA cell configuration mode and configuration timing according to whether the handover request message carries the cell selection list and whether the second status indication value of the traffic switch of the CA cell is reconfigured when the traffic reaches the threshold.

In step 104, the CA cells are configured at corresponding configuration occasions according to the determined configuration manner.

In one possible implementation manner, if the coverage relationship is completely the same coverage, in step 102, the configuration mode and the configuration timing of the corresponding CA cell are determined, including the following three cases:

case 1: if the first state indication value indicates to directly configure the CA cell, the second state indication value does not indicate that the traffic volume reaches the threshold, the CA cell is reconfigured, and the CA cell is determined to be configured directly according to the measurement result of the neighbor cell.

Case 2: if the first state indicated value indicates to directly configure the CA cell, the second state indicated value indicates to reconfigure the CA cell when the traffic volume reaches the threshold, the handover request message carries a candidate cell list, and the CA cell is configured according to the measurement result of the auxiliary cell of the candidate cell list.

Case 3: if the first state indicated value indicates to directly configure the CA cell, the second state indicated value indicates that the CA cell is reconfigured when the traffic volume reaches a threshold, the candidate cell list is not carried in the switching request message, and when the traffic volume reaches a set traffic threshold, the CA cell is determined to be directly configured.

In another possible implementation manner, if the coverage relationship is completely the same coverage, in step 102, the configuration mode and the configuration timing of the corresponding CA cell are determined, including the following three cases:

case 4: if the first status indication value does not indicate to directly configure the CA cell, the handover request message carries a candidate cell list, and the CA cell is configured according to the measurement result of the auxiliary cell of the candidate cell list.

Case 5: if the first state indication value does not indicate to directly configure the CA cell, the switching request message does not carry the candidate cell list, and the second state indication value indicates that the service volume reaches the threshold, the CA cell is reconfigured, and when the service volume reaches the set service threshold, the CA cell is configured according to the measurement result of the neighbor cell.

Case 6: if the first state indication value does not indicate to directly configure the CA cell, the switching request message does not carry the candidate cell list, and if the second state indication value does not indicate that the traffic volume reaches the threshold, the CA cell is reconfigured, after the cell is switched, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

For the scenario that the coverage relationship between the target cell and the neighboring cell is completely the same coverage, the embodiment of the application will check the CA configuration, the blind configuration switch and the traffic switch of the target cell, and distinguish different configuration modes and opportunities according to the configuration conditions. The blind configuration switch is used for checking whether the CA cell is directly configured or not and corresponds to the first state indication value, the traffic switch is used for checking that the subsequent CA configuration is performed after the traffic data volume reaches the threshold and corresponds to the second state indication value.

If the blind configuration switch is turned on and the traffic switch is turned off, that is, corresponding to the above case 1, the first status indication value indicates to configure the CA cell directly, and the second status indication value does not indicate to reconfigure the CA cell when the traffic reaches the threshold, then the CA cell is configured directly in the handover process.

If the switch is configured blindly and the traffic switch is on, i.e. corresponding to the above case 2, the first status indication value indicates to configure the CA cell directly, the second status indication value indicates to reconfigure the CA cell when the traffic reaches the threshold, determine whether the handover request message carries candidatecellnfolist, and if the handover request message carries candidate cell list and contains the measurement results of some SCELLs of the destination cell, configure the CA cell according to the measurement results of the secondary cells of the candidate cell list for these SCELLs; if the handover request message does not carry the candidate cell list, i.e. corresponding to the above case 3, the handover request message does not carry the candidate cell list, the CA cell is not directly configured, and when the traffic volume reaches the set traffic threshold, the CA cell is reconfigured.

If the blind configuration switch is closed, the traffic switch is opened, whether a candidate cell list is carried in the switching request message is judged, and if the candidate cell list is carried in the switching request message, the CA cell is configured according to the measurement result of the auxiliary cell of the candidate cell list corresponding to the situation 4; if the handover request message does not carry the candidate cell list, corresponding to the above case 5, when the traffic volume reaches the set traffic threshold, the CA cell is configured according to the measurement result of the neighbor cell.

If the blind configuration switch and the traffic switch are both turned off and the source side handover request message does not carry the candidate cell list, corresponding to the above case 6, the embodiment of the present application configures CA related measurements after cell handover, and reconfigures CA cells when the measurement result reaches the measurement threshold.

In one possible implementation manner, if the coverage relationship is not completely identical coverage, in step 103, the configuration mode and the configuration timing of the corresponding CA cell are determined, including the following three cases:

case 7: if the handover request message carries the candidate cell list, determining to configure the CA cell directly according to the measurement result of the auxiliary cell of the candidate cell list.

Case 8: if the switching request message does not carry the candidate cell list, the CA cell is reconfigured when the second state indication value does not indicate that the traffic volume reaches the threshold, CA related measurement is configured after the cell is switched, and the CA cell is reconfigured when the measurement result reaches the measurement threshold.

Case 9: if the handover request message does not carry the candidate cell list, the second state indication value indicates that the traffic volume reaches a threshold, the CA cell is reconfigured, the CA related measurement is configured when the traffic volume reaches a set traffic threshold, and the CA cell is reconfigured when the measurement result reaches a measurement threshold.

For the scenario that the coverage relationship between the destination cell and the neighboring cell is not completely same, when the configuration strategy is executed, whether a candidate cell list is carried in a switching request message of a switching source side or not is needed to be depended on, wherein the candidate cell list carries frequency point information of a service cell, strongest neighboring cell information of the service cell, frequency point information and strongest neighboring cell information of a secondary cell and frequency point information of a switching measurement object.

When the handover request message of the source side carries the candidate cell list, for the target side, the measurement frequency point information and the measurement result of the CA relation cell to be configured are obtained, so that the CA cell can be configured directly according to the measurement result of the secondary cell of the candidate cell list, the measurement frequency point information of the CA relation cell does not need to be configured, and SCELL is added after the measurement result of the CA relation cell is obtained, which corresponds to the above case 7.

When the blind configuration switch is turned on and the traffic switch is turned off, if the source side handover request message carries the candidate cell list, corresponding to the above case 7, determining to directly configure the CA cell according to the measurement result of the auxiliary cell of the candidate cell list; otherwise, if the source side switching request message does not carry the candidate cell list, corresponding to the above case 8, after the cell is switched, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

When the blind configuration switch and the traffic switch are simultaneously opened, if the source side switching request message carries a candidate cell list, corresponding to the above case 7, determining to directly configure the CA cell according to the measurement result of the auxiliary cell of the candidate cell list; otherwise, if the source side handover request message does not carry the candidate cell list, corresponding to the above-mentioned case 9, when the traffic volume reaches the set traffic threshold, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

When the blind configuration switch is closed and the traffic switch is opened, if the source side switching request message carries the candidate cell list, corresponding to the above case 7, determining to directly configure the CA cell according to the measurement result of the auxiliary cell of the candidate cell list; otherwise, if the source side handover request message does not carry the candidate cell list, corresponding to the above-mentioned case 9, when the traffic volume reaches the set traffic threshold, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

When the blind configuration switch and the traffic switch are both closed, if the source side switching request message carries a candidate cell list, corresponding to the above case 7, determining to directly configure the CA cell according to the measurement result of the auxiliary cell of the candidate cell list; otherwise, if the source side switching request message does not carry the candidate cell list, corresponding to the above case 8, after the cell is switched, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

In a possible implementation manner, in the foregoing case 1 and case 5, the CA cell is configured according to the measurement result of the neighboring cell, and the flow chart is shown in fig. 2, and includes the following contents:

in step 201, when it is determined that there are a plurality of secondary cells to be configured that satisfy the condition according to the measurement result of the neighboring cells, one secondary cell to be configured is selected and sent to the source cell through a handover command, so that the source cell notifies the UE through an RRC reconfiguration message. For example, according to the measurement result of the neighboring cells, it is determined that there are 4 secondary cells to be configured that satisfy the conditions, which are A, B, C, D respectively, and one secondary cell is selected to be sent to the source cell through a handover command, for example, a is sent to the source cell through a handover command, so that the source cell notifies the user terminal UE through an RRC reconfiguration message.

In step 202, for the remaining secondary cells to be configured that meet the conditions, configuration is performed by adopting a serial configuration mode after the cell switching is completed. For the other secondary cells to be configured, such as the secondary cell B, C, D to be configured, which meets the conditions, the secondary cells to be configured are configured in a serial configuration mode after the cell switching is completed.

In a possible implementation manner, for the above case 2, case 4, and case 7, the CA cell is configured according to the measurement result of the secondary cell of the candidate cell list, and the flow chart is shown in fig. 3, and includes the following contents:

In step 301, according to the measurement results of the secondary cells of the candidate cell list, when it is determined that there are a plurality of secondary cells to be configured that meet the conditions, one secondary cell to be configured is selected and sent to the source cell through a handover command, so that the source cell notifies the user terminal UE through an RRC reconfiguration message. For example, in the measurement results of the secondary cells in the candidate cell list, there are 4 secondary cells to be configured that meet the conditions, which are A, B, C, D respectively, and one secondary cell is selected to be sent to the source cell through a handover command, for example, B is sent to the source cell through a handover command, so that the source cell notifies the UE through an RRC reconfiguration message. It should be noted that, the conditions satisfied by the secondary cell to be configured that satisfies the conditions may be conditions that the cell signal strength is greater than a certain threshold, etc., where the conditions satisfied by the secondary cell to be configured in the present application are consistent with the conditions satisfied by the secondary cell to be configured in the related technology.

In step 302, for the remaining secondary cells to be configured that meet the conditions, configuration is performed by adopting a serial configuration mode after the cell switching is completed. For the other secondary cells to be configured, such as the secondary cell A, C, D to be configured, which meets the conditions, the secondary cells to be configured are configured in a serial configuration mode after the cell switching is completed.

In one possible implementation manner, if the first status indication value indicates to directly configure the CA cell, and the second status indication value indicates to reconfigure the CA cell when the traffic volume reaches the threshold, the handover request message carries a candidate cell list, and for the remaining secondary cells to be configured that meet the condition, the secondary cells to be configured are configured in a serial configuration manner after the cell handover is completed, including the following contents:

and for the rest auxiliary cells to be configured meeting the conditions, after the cell switching is completed, determining that the traffic volume reaches the set traffic threshold, and configuring the auxiliary cells by adopting a serial configuration mode. Namely, corresponding to the case 2, for the rest auxiliary cells to be configured meeting the conditions, the configuration time comprises the time when the switching of the cells is completed and the service volume is determined to reach the set service threshold, the two configuration time are not necessary, and the CA cell configuration is carried out in a serial configuration mode under the condition that the continuous configuration time is met.

According to the embodiment of the invention, the configuration of the CA cells is realized under different configuration conditions, a plurality of auxiliary cells to be configured meeting the conditions can be configured, and according to different conditions of whether the candidate cell list is carried in the switching request message, whether the first state indication value of the blind configuration switch of the carrier aggregation CA cells is directly configured, and whether the second state indication value of the traffic switch of the CA cells is reconfigured when the traffic reaches the threshold, the configuration time and the configuration mode are more various, so that the requirement of flexible use of users can be met.

In one possible implementation manner, if the CA cell to be configured is configured when the terminal switches the source cell, deleting the cell which is configured and belongs to the CA cell to be configured, and reconfiguring the CA cell at the corresponding configuration occasion according to the determined configuration mode. According to the embodiment of the application, the service rate of the user is improved by configuring the CA and the strategy of de-configuring the CA.

In one possible implementation, the overall flow chart of the CA cell configuration in the case that the co-coverage relationship is completely co-coverage is shown in fig. 4, which includes the following contents:

in step 401, a handover request message of a source cell is received, and it is determined that a coverage relationship between a target cell and a neighboring cell for handover is completely identical coverage.

In step 402, it is determined whether the first status indication value indicates that the CA cell is directly configured.

If the first status indication value indicates direct CA cell configuration, in step 403, it is determined whether the second status indication value indicates that the traffic volume reaches a threshold, and the CA cell is reconfigured.

If the second status indication value does not indicate that the traffic volume reaches the threshold, the CA cell is reconfigured, and in step 404, the CA cell is configured. The specific configuration mode of the CA cell is that the CA cell is directly configured according to the measurement result of the neighbor cell.

If the second status indication value indicates that the traffic volume reaches the threshold, the CA cell is reconfigured, and in step 405, it is determined whether the handover request message carries a candidate cell list.

If the handover request message carries the candidate cell list, step 404 is executed to configure the CA cell. The specific configuration of the CA cell is that the CA cell is configured according to the measurement result of the auxiliary cell of the candidate cell list.

If the handover request message does not carry the candidate cell list, in step 406, when the traffic volume reaches the set traffic threshold, step 404 is performed. I.e. when the traffic reaches the set traffic threshold, it is determined to configure the CA cell directly.

If the first status indication value does not indicate direct configuration of the CA cell, in step 407, it is determined whether the handover request message carries a candidate cell list.

If the handover request message does not carry the candidate cell list, in step 408, it is determined whether the second status indication value indicates that the traffic volume reaches a threshold, and the CA cell is reconfigured.

If the second status indication value indicates that the traffic volume reaches the threshold, the CA cell is reconfigured, and in step 409, when the traffic volume reaches the set traffic threshold, step 404 is performed. I.e. when the traffic reaches the set traffic threshold, it is determined to configure the CA cell directly.

If the second status indication value does not indicate that the traffic volume reaches the threshold, the CA cell is reconfigured, in step 410, CA-related measurements are configured after cell handover, and when the measurement result reaches the measurement threshold, step 404 is performed. And after the cell is switched, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

In one possible implementation, an overall flow chart of CA cell configuration in the case that the co-coverage relationship is not completely co-coverage is shown in fig. 5, which includes the following contents:

in step 501, a handover request message of a source cell is received, and it is determined that a coverage relationship between a target cell and a neighboring cell for handover is not completely identical coverage.

In step 502, it is determined whether the handover request message carries a candidate cell list.

If the handover request message carries a candidate cell list, in step 503, the CA cell is configured. The specific configuration of the CA cell is that the CA cell is directly configured according to the measurement result of the auxiliary cell of the candidate cell list.

If the handover request message does not carry the candidate cell list, in step 504, it is determined whether the second status indication value indicates that the traffic volume reaches a threshold, and the CA cell is reconfigured.

If the second status indication value does not indicate that the traffic volume reaches the threshold, the CA cell is reconfigured, in step 505, CA related measurement is configured after cell handover, and when the measurement result reaches the measurement threshold, step 503 is executed. And after the cell is switched, the CA related measurement is configured, and when the measurement result reaches the measurement threshold, the CA cell is reconfigured.

If the second status indication value indicates that the traffic volume reaches the threshold, the CA cell is reconfigured, in step 506, CA related measurements are configured when the traffic volume reaches the set traffic threshold, and step 503 is executed when the measurement result reaches the measurement threshold. Namely, when the traffic volume reaches the set traffic threshold, CA related measurement is configured, and when the measurement result reaches the measurement threshold, CA cells are reconfigured.

In summary, according to the configuration situation of the terminal at the base station of the handover source side and the target side, the embodiments of the present application provide the configuration mode and the configuration opportunity of the CA cell, ensure that the CA cell is configured in different application scenarios, and are not limited by whether the handover request necessarily carries the candidate cell list, so that the CA cell can be configured in the handover request.

a handover request message receiving module 601 configured to receive a handover request message of a source cell, and determine a coverage relationship between a target cell and a neighboring cell for handover;

the first configuration information determining module 602 is configured to determine, if the coverage relationship is completely the same coverage, a configuration mode and a configuration opportunity of the corresponding CA cell according to whether the handover request message carries a candidate cell list, whether a first status indication value of a blind configuration switch of the carrier aggregation CA cell is directly configured, and whether the traffic reaches a threshold, and then, a second status indication value of a traffic switch of the CA cell is configured;

a second configuration information determining module 603, configured to determine a configuration mode and a configuration opportunity of the corresponding CA cell according to whether the handover request message carries a cell selection list and a second status indication value of a traffic switch of the CA cell when the traffic reaches a threshold if the coverage relationship is not completely the same coverage;

In a possible implementation manner, the configuring the CA cell directly according to the measurement result of the neighboring cell is performed, and the first configuration information determining module or the second configuration information determining module is configured to:
