Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring an auxiliary carrier.
Background
In an Advanced long term evolution (LTE-a) system, the peak rate design target is downlink 1Gbps and uplink 500Mbps, and to meet this requirement, the third Generation Partnership Project (3 GPP) proposes to introduce a Carrier Aggregation (CA) technology into LTE-a to extend the transmission bandwidth to 100MHz, so as to provide a high transmission rate.
CA technology is to aggregate two or more component carriers together to provide a wider transmission bandwidth. The underlying objective is to aggregate multiple relatively narrow-band carriers into a wider spectrum, thereby providing a larger transmission bandwidth and higher transmission rate. A component carrier to which User Equipment (UE) is connected is referred to as a primary carrier; the other component carriers are called secondary carriers.
The current implementation mode of the base station for the CA secondary carrier configuration common strategy is as follows:
when the UE is accessed, the capability of the UE and the switch of the base station are judged, and the measurement for the auxiliary carrier configuration, which is supported by the UE and is used for appointing the frequency point corresponding to the CA relationship, is configured for the UE;
when the measurement for the auxiliary carrier configuration reports the neighbor cell in the designated CA relationship, the base station configures the cell for the auxiliary carrier for the UE, and configures the measurement for the auxiliary carrier deletion for the UE;
then, when the service data volume of the UE counted by the layer 2(L2) on the base station side reaches a preset threshold, L2 activates the secondary cell through a Media Access Control (MAC) layer. Wherein the L2 refers to L2 in the LTE protocol stack, and includes three sublayers: a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and an MAC layer.
However, the method for configuring the secondary carrier for the UE in the prior art has the following disadvantages:
there are cases where control channel resources are wasted. When configuring the secondary carrier, whether the Quality of Service (QoS) of the UE needs to be configured is not considered, and if there is only a UE with small packet data, the secondary carrier is also configured. But the secondary carrier is not activated at L2 due to insufficient data volume, which wastes some control channel resources (PUCCH2, PUCCH 1BCS resources) configured for the UE due to the configuration of the secondary carrier, and may also result in that the secondary carrier of the following large-data-volume UE cannot be configured.
When the UE has a high QoS requirement during access, the time delay of the auxiliary carrier configuration is larger. If the UE has data with higher QoS during access, the auxiliary carrier configuration needs to be configured first, and then the auxiliary carrier configuration needs to be configured after the UE to be measured reports to the designated cell.
In the current scheme, because the QoS factor is not considered, the delay sensing and service sensing of the LTE Voice service (VoLTE) UE or the real-time streaming media UE cannot be better guaranteed. At present, operators are mainly pushing VoLTE and video call technologies, and the current scheme is not beneficial to the popularization of the services.

Detailed Description
The embodiment of the application provides an auxiliary carrier configuration method and device, which are used for configuring an auxiliary carrier for user equipment based on QoS (quality of service) of a bearer established for the user equipment, so that resource waste is avoided, and system performance is improved.
In an LTE-a system, Carrier Aggregation (CA) is a good method for increasing the peak rate of a single UE and meeting the increasing rate requirements of the UE by using other idle air frequency bands. With the popularization of the current external field CA, in order to further reduce the UE auxiliary carrier configuration delay and further improve the number of CA UEs that can be actually activated by the base station by reasonably utilizing the air interface resources of the control channel under the current circumstances of more and more UEs supporting the CA, more and more usage scenarios, and a large environment requiring higher and higher data transmission delay, a scheme for performing CA auxiliary carrier configuration according to the QoS of the UE is provided in the embodiment of the present application.
Referring to fig. 1, a method for configuring a secondary carrier provided in an embodiment of the present application includes:
s101, determining that a bearer needs to be established for user equipment;
s102, judging whether to configure an auxiliary carrier for the user equipment according to the QoS of the bearer established for the user equipment as required.
For example, in the CA secondary carrier configuration scheme based on QoS provided in the embodiment of the present application, when a Guaranteed Bit Rate (GBR) bearer of a certain service type is established, whether secondary carrier configuration can be directly performed is determined according to a Guaranteed Rate of the GBR bearer QoS configured by a core network. Optionally, the configured secondary carrier is selected according to the secondary carrier in the CA relationship configured by the base station, and the secondary carrier supported by the UE is selected to be directly configured.
For other non-specified GBR bearers or NGBR bearers, after the bearer is established, the secondary carrier configuration processing may be performed according to the actual data volume of the UE detected by the layer 2 on the subsequent base station side.
Therefore, optionally, when the bearer is a pre-configured specified bearer, whether to configure the secondary carrier for the user equipment is determined according to a quality of service QoS of the bearer that needs to be established for the user equipment.
Optionally, the determining, according to the quality of service QoS of the bearer established for the user equipment as needed, whether to configure the secondary carrier for the user equipment specifically includes:
when the QoS guarantee rate of the specified bearer reaches a preset threshold, configuring an auxiliary carrier for the user equipment in the process of establishing the bearer; otherwise, the layer 2 on the base station side monitors the data volume of the user equipment.
Optionally, in the process of monitoring the data volume of the user equipment by the layer 2 at the base station side, the method further includes:
and if the data volume of the user equipment monitored by the layer 2 on the base station side reaches a preset threshold, configuring an auxiliary carrier for the user equipment.
For example, when a GBR bearer of a specified service type is established, whether a certain threshold is reached is judged according to the sum of QoS guarantee rates of all GBR bearers of the UE, and if the threshold is reached, an auxiliary carrier is directly configured during bearer establishment; if the data quantity of the UE is less than the threshold, the layer 2 monitors the data quantity of the UE, when the data quantity reaches a certain threshold, the auxiliary carrier is directly configured, and the auxiliary carrier frequency point is configured for A2 measurement of auxiliary carrier deletion.
For the GBR bearer of the specified service type, the GBR bearer of QoS Class Identifier (QCI) 1\2\3 may be preconfigured as the GBR bearer of the specified service type, and according to the protocol, the bearer transmission delay of QCI1\2\3 is all below 150ms, which belongs to the bearer with higher delay requirement, and of course, the specified bearer may also be configured and controlled flexibly by the base station.
Optionally, the method further comprises: and when the bearer is a pre-configured non-designated bearer, judging whether to configure the auxiliary carrier for the user equipment according to the actual data volume of the user equipment counted by the base station side layer 2.
Optionally, the determining, according to the actual data amount of the ue counted by the base station side layer 2, whether to configure the secondary carrier for the ue specifically includes:
and if the data volume of the user equipment monitored by the layer 2 on the base station side reaches a preset threshold, configuring an auxiliary carrier for the user equipment.
For example, when other GBR bearers or NGBR bearers are established, the data amount of the UE is directly monitored by layer 2, when the data amount reaches a certain threshold, the secondary carrier is directly configured, and the frequency point of the secondary carrier is configured to measure a2 that can be used for deleting the secondary carrier.
Optionally, when the secondary carrier is configured for the user equipment, the method further includes: and configuring A2 measurement for deleting the auxiliary carrier for the frequency point of the auxiliary carrier for the user equipment.
Optionally, the method further comprises: and when the A2 measurement report of the user equipment is received, deleting the secondary carrier configured for the user equipment.
Optionally, when receiving the a2 measurement report of the user equipment, the method further comprises: configuring A4 measurement for configuring a secondary carrier for the user equipment, and reconfiguring the secondary carrier for the user equipment when receiving an A4 measurement report of the user equipment.
That is to say, when the a2 measurement report of the secondary carrier deletion indicates that the channel condition of the UE on the secondary carrier is not good at this time, the secondary carrier may be deleted to ensure the overall service quality, and the a4 measurement that can be used for secondary carrier configuration is configured for the secondary carrier frequency point to wait for the signal enhancement of the UE on the secondary carrier. When the a4 reports the cell, the UE is considered to have increased channel conditions for the secondary carrier to satisfy the service, and the cell is configured as the secondary carrier again.
Optionally, the method further comprises:
when deleting the part of the bearers established for the user equipment, judging whether the sum of the QoS guarantee rates of the rest specified bearers of the user equipment reaches a preset threshold, if so, keeping the auxiliary carrier configuration of the user equipment, otherwise, deleting at least one auxiliary carrier of the user equipment, monitoring the data volume of the user equipment through a layer 2 at a base station side, and judging whether to perform subsequent auxiliary carrier configuration for the user equipment.
For example, when bearer deletion occurs, it is determined again whether the sum of the QoS guaranteed rates of the remaining specified GBR bearers can reach the threshold, and if so, secondary carrier configuration is continuously maintained; if the data volume is lower than the threshold, deleting the auxiliary carrier, monitoring the UE data volume by the layer 2, and then carrying out subsequent auxiliary carrier configuration judgment processing.
Optionally, configuring a secondary carrier for the ue, specifically including: and configuring the auxiliary carriers with the number of the auxiliary carriers corresponding to the preset range for the user equipment according to the preset range to which the QoS guarantee rate belongs.
For example, the UE needs to configure several secondary carriers, and may be controlled by several rate thresholds when the base station configures different numbers of secondary carriers. When the rate meets which threshold, several secondary carriers are configured. For example: configuring an auxiliary carrier number threshold (5 th): 30M/50M/70M/90M/100M, when the OQS guaranteed rate or the layer 2 monitoring rate reaches 30M, configuring 1 auxiliary carrier by priority, and the like.

To sum up, the embodiments of the present application provide a method for performing secondary carrier configuration by using a QoS guaranteed rate configured by a core network or using an actual rate of a base station layer 2 for different types of bearers, where the secondary carrier configuration is directly performed according to the QoS guaranteed rate without waiting for measurement reporting for configuration. After the CA secondary carrier is configured, if the secondary carrier is deleted due to poor signal quality of the secondary carrier (reported by a 2), the configuration of the secondary carrier is triggered. After the CA secondary carrier is configured, if the secondary carrier is deleted due to bearer deletion, the secondary carrier may be configured by triggering. In summary, the embodiment of the application can further reduce the time delay of the UE secondary carrier configuration when the UE accesses the GBR bearer with a certain rate requirement, and quickly increase the UE rate, so as to achieve the purpose of increasing the UE sensing. The auxiliary carrier configuration can be carried out when the GBR and NGBR load of the UE really have data transmission with a certain rate, so that the waste of air interface resources of a control channel caused by the auxiliary carrier configuration in advance is avoided. The saved control channel resources can be configured for other UE which actually needs the auxiliary carrier in the cell, so that the problems that the UE which actually needs to configure the auxiliary carrier cannot be positioned due to insufficient control channel resources, and the UE which configures the auxiliary carrier does not activate the auxiliary carrier due to less data, and resources are wasted are solved.
