Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing an auxiliary carrier.
Background
In order to satisfy the requirement that Long Term Evolution-Advanced (Long Term Evolution-Advanced, abbreviated as LTE-Advanced) supports the peak rate of downlink 1Gbit/s and uplink 500Mbit/s, the transmission bandwidth needs to reach 100MHz, however, in practice, there are few continuous available spectrum resources, so the LTE-Advanced adopts Carrier Aggregation (CA) technology to aggregate a plurality of Component carriers (Component carriers, abbreviated as CCs) to achieve high-bandwidth transmission. In order to reasonably utilize system resources and maximize system performance, it is necessary to perform management, carrier management for short, on a serving cell of a UE with CA capability. After a base station configures and activates a Secondary serving Cell (SCell) for a user equipment (user equipment, abbreviated as UE) supporting carrier aggregation, the UE needs to keep in multiple cells to monitor and decode control channels and transmit uplink control information, which greatly increases energy consumption of the UE. And considering that the packet service is usually in the form of data burst, the UE performing carrier aggregation rarely needs a large transmission bandwidth continuously, and when the bandwidth requirement is relatively small, keeping the UE performing control channel listening and decoding in multiple cells is very unfavorable for power saving of the UE, so the third Generation Partnership Project (3rd Generation Partnership Project, 3GPP for short) introduces an activation/deactivation mechanism for the SCell.
However, the prior art lacks a resource evaluation criterion and does not provide a method for determining the number of activated/deactivated carriers, and if all configured carriers are directly activated or deactivated, frequent activation and deactivation decisions are triggered, so that the stability of the SCell rate is reduced, and the overall performance of the base station is affected.

Fig. 1 exemplarily shows a flow of a method for processing a secondary carrier according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following specific steps:
step S101, determining a user to be processed according to the processing state of the current service of the user, wherein the user to be processed is a user needing to execute carrier activation or deactivation;
step S102, determining available resources of configured carriers of a user to be processed;
step S103, determining an auxiliary carrier to be processed according to the resource demand of the current service of the user to be processed and the available resources of the configured carrier;
and step S104, executing corresponding activation or deactivation processing on the secondary carrier to be processed.
In a specific embodiment, the processing state of the current service of the user refers to user service perception, which may include user service satisfaction, user service rate, and the like; in this embodiment, a user supports carrier aggregation, so that the user configures one main carrier and configures one or more auxiliary carriers, where the main carrier is always in an activated state and cannot be deactivated, the auxiliary carriers may perform activation or deactivation processing according to a processing state of a current service of the user, a base station periodically queries the processing state of the current service of the user, and a set period may be determined according to a specific situation.
By the method, on one hand, according to the processing state of the current service of the user, resources are guaranteed to be preferentially distributed to the users whose current service processing state cannot meet the user requirements, so that the user satisfaction is improved; meanwhile, the residual resources except the resources meeting the basic requirements of the users are distributed to other users needing the resources, so that the purpose of reasonably distributing the resources is achieved; on the other hand, the resources are pre-estimated, the number of carriers needing to be activated or deactivated is determined, the impact of simultaneous activation on system load or the influence of simultaneous deactivation on the performance of a user system are reduced, and the overall performance of the base station is effectively improved.
Optionally, determining a user to be processed according to a processing state of a current service of the user includes:
comparing the processing state of the current service of the user with a first sensing threshold of the current service, and if the processing state of the current service of the user is smaller than the first sensing threshold, determining the user as a user to be processed, which needs to be subjected to carrier activation;
and comparing the processing state of the current service of the user with a second sensing threshold of the current service, and if the processing state of the current service of the user is greater than the second sensing threshold, determining the user as a user to be processed, which needs to perform carrier deactivation.
In specific implementation, the first sensing threshold and the second sensing threshold may be preset service sensing thresholds, the preset service sensing thresholds may be distinguished according to service types, and different thresholds are set for different services; for example, when the user service rate is selected as the user service perception, the preset service perception threshold may be set to 8Mbps for the high definition video streaming user, the preset service perception threshold may be set to 4Mbps for the standard definition video streaming user, the preset service perception threshold may be set to 0.05Mbps for the HTTP web browsing user, and the preset service perception threshold may be set to 20Mbps or more for the FTP download user. Setting a user A as a high-definition video stream user, wherein the current service rate of the user A is 3.9Mbps, a preset service perception threshold is 8Mbps, and the current service rate of the user A is less than the preset service perception threshold, so that the user A is a user to be processed, which needs to be activated by carrier waves; and setting the user B as a standard definition video stream user, wherein the current service rate of the user B is 7Mbps, the preset service perception threshold is 4Mbps, and the current service rate of the user B is greater than the preset service perception threshold, so that the user B is a user to be processed, which needs to perform carrier deactivation.
When judging whether the user carries out activation or deactivation operation, the processing state of the current service of the user is compared with a preset service perception threshold, so that the user whose processing state does not meet the user requirement can carry out activation operation on the carrier to achieve the basic service requirement, the user satisfaction is improved, and in addition, the residual resources except the user basic requirement are distributed to other users requiring the resources, thereby achieving the purpose of reasonably distributing the resources.

In specific implementation, according to the resource demand of the current service of the user to be processed, a resource matching the user resource demand is selected from available resources of each configured carrier, and the corresponding configured carrier is determined as the carrier to be processed, and since the main carrier cannot be deactivated, the finally determined carrier to be processed is the auxiliary carrier to be processed. In order to more clearly introduce the determination process of the secondary carrier to be processed, the embodiments of the present invention provide the following examples, which are divided into two cases according to whether the user to be processed is a user needing carrier activation and a user needing carrier deactivation:
in case one, when the user to be processed is a user needing carrier activation, the loads of the secondary carriers F1, F2, F3, and F4 configured by the user a are respectively 63%, 65%, 60%, and 64%, the preset load threshold is 70%, the secondary carriers meeting the load lower than the preset load threshold are respectively F1, F2, F3, and F4, the secondary carrier to be processed by the user a may be determined in four secondary carriers F1, F2, F3, and F4, and the four secondary carriers are ranked from low to high according to the load conditions to obtain: f3, F1, F4 and F2, the available resources of the four auxiliary carriers are respectively 10PRB, 7PRB, 6PRB and 5PRB, the available resources of the ordered auxiliary carriers are sequentially accumulated, the process is that 10PRB +7PRB is 17PRB to obtain a first accumulated sum of 17PBR, 10PRB +7PRB +6PBR is 23PBR to obtain a second accumulated sum of 23PBR, 10PRB +7PRB +6PBR +5PBR is 28PBR to obtain a third accumulated sum of 28PBR, in the specific implementation, it is not necessary to calculate the accumulated sum of each time, after the first accumulated sum is obtained by calculation, it is determined whether the first accumulated sum is greater than the resource demand of the current service of the user a, the resource demand of the current service of the user a is 13PRB, since the sum 17PBR of the first accumulation is greater than the resource demand 13PRB for the current service of the user a, the secondary carriers participating in the accumulation are F3 and F1, the secondary carriers F3 and F1 participating in the accumulation are determined as the pending secondary carriers to be activated.
In the second case, when the user to be processed is a user needing carrier deactivation, the available resource of the user B primary carrier F2 is 11PBR, and the resource demand of the user B current service is 12PBR, so the available resource of the user B primary carrier F2 cannot meet the resource demand of the user B current service. The loads of the auxiliary carriers F1 and F3 are 63% and 60% respectively, F3 and F1 are obtained after sorting according to the low to high loads, the available resources of the auxiliary carriers F3 and F1 are 16PRB and 15PRB respectively, the available resources of the main carrier F2 are accumulated with the available resources of the sorted auxiliary carriers F3 and F1 respectively, and the sum of the accumulated available resources is respectively: as can be seen from the above description, F3 and F2 satisfy that the accumulated available resources are greater than the required resource amount, and the load of the auxiliary carrier F3 is smaller than the load of the auxiliary carrier F1, so that the auxiliary carrier F3 is selected to remain activated, and the auxiliary carrier F1 is determined as the to-be-processed auxiliary carrier that needs to be deactivated.
The auxiliary carrier to be processed is determined according to the user required resource to be processed and the available resource of the carrier configured by the user to be processed, the number of carriers which need to be increased or decreased by the user is accurately evaluated, the waste of user power caused by multiple activated carriers is effectively avoided, and the impact on system load caused by simultaneous activation or the influence on user performance caused by simultaneous deactivation are reduced; in addition, when the process of determining the auxiliary carrier to be processed is carried out, the load condition of the configured carrier of the user to be processed is considered at the same time, the carrier with low load is ensured to be activated preferentially, the carrier with high load is ensured to be deactivated preferentially, the system resource is utilized to the maximum extent, and the load balance among the carriers is achieved.
The embodiment of the invention provides a method and a device for processing auxiliary carriers, which are used for determining a user to be processed according to the processing state of the current service of the user, wherein the user to be processed is a user needing to execute carrier activation or deactivation; determining available resources of configured carriers of a user to be processed; determining an auxiliary carrier to be processed according to the resource demand of the current service of the user to be processed and the available resources of the configured carrier; and executing corresponding activation or deactivation processing on the secondary carrier to be processed. Because the processing states of the current services of different users are different, the processing state of the current service of a part of users cannot meet the basic requirements of the users, and the part of users need to execute carrier activation; if the processing state of the current service of another part of users may far meet the basic requirements of the users, the part of users need to execute carrier deactivation, so that the users to be processed need to be determined according to the processing state of the current service of the users before the carrier activation or deactivation operation is performed; because the user to be processed configures a plurality of carriers, before determining the number of activated carriers and the number of deactivated carriers, the available resources of the configured carriers of the user to be processed need to be determined, and simultaneously the resource demand of the current service of the user to be processed also needs to be determined; in order to ensure that the current service state of a user to be processed can meet the basic requirements of the user and simultaneously enable carrier resources to be uniformly distributed to avoid resource waste, the auxiliary carrier to be processed is determined according to the relation between the resource demand of the current service of the user to be processed and available resources of configured carriers; and after the auxiliary carrier to be processed is determined, activating or deactivating the corresponding auxiliary carrier so that the processing state of the current service of the user to be processed just meets the basic requirements of the user. On one hand, according to the current service processing state of the user, the embodiment of the invention ensures that the resources are preferentially distributed to the users whose current service processing state can not meet the user requirements, thereby improving the user satisfaction; on the other hand, the required resources and the available resources are estimated, the number of the activated or deactivated carriers is determined, the impact of simultaneous activation on system load or the influence of simultaneous deactivation on the performance of a user system is reduced, and the overall performance of the base station is effectively improved.
