The following describes in detail the dual carrier scheme configuration method provided by the embodiment of the present disclosure through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 1 is one of the step flowcharts of the dual carrier scheme configuration method provided in the embodiment of the present disclosure. The method is applied to a base station, as shown in fig. 1, and may include the following steps 110 to 120.
Step 110, acquiring data transmission parameters in the service, wherein the data transmission parameters are used for representing performance characteristics of data transmission in the service.
The service refers to related services such as provided numbers, voice, data and the like, and with the alternation and rapid deployment of the mobile communication network, the service of the mobile communication network plays an important role in the communication of people, objects and objects, and meets different service requirements such as telemedicine, autopilot, intelligent home, industrial production, environmental monitoring and the like. Since the service is implemented based on the process of data transmission in the mobile communication network, the performance of data transmission directly affects the quality of service. The base station is an interface device of a mobile device access network in a mobile communication network, can provide wireless coverage, realizes wireless signal transmission between a wired communication network and a wireless terminal, carries out information transfer between a core network and the mobile device, and can effectively improve the performance of data transmission in the network and meet different service requirements by realizing a dual carrier configuration scheme at the base station side.
In the embodiment of the disclosure, the data transmission parameters may be obtained to characterize the performance characteristics of data transmission in the service, where, according to different characterization modes, the performance characteristics of data transmission may generally include a transmission rate, throughput, time delay, bit error rate, and the like.
Step 120, configuring a dual-carrier scheme corresponding to the data transmission parameters for the service according to a dual-carrier scheme configuration condition, wherein the dual-carrier scheme comprises any one of a carrier aggregation scheme and a dual-connection scheme, and the dual-carrier scheme configuration condition comprises a corresponding configuration relation between the data transmission parameters and the dual-carrier scheme.
The dual carrier scheme can improve uplink and downlink bandwidths, transmission rates, stability and the like through integrating dispersed frequency bands so as to meet the data transmission performance requirements corresponding to service growth.
In an embodiment of the method disclosed in the present disclosure, the dual-carrier scheme may include a carrier aggregation scheme, a dual-connection scheme, and the like, where different dual-carrier schemes have different characteristics and advantages in application, so as to adapt to different network environments and meet different service requirements. For example, the carrier aggregation can solve the problem of limited uplink coverage by scheduling low-frequency uplink resources, can meet the service requirement of enhancing the uplink coverage of a cell edge area, and can effectively increase the bandwidth of a downlink system to achieve an effective capacity improvement effect, so that the carrier aggregation is also suitable for the service requirement of large bandwidth to improve the capacity; the dual-connection scheme is respectively scheduled by the main node and the auxiliary node, the data transmission is carried out in a split-flow mode, the reliability of the data transmission is good, the dual-connection scheme is suitable for asynchronous deployment in a network, and the service requirement of the reliability of the data transmission can be met.
In the embodiment of the disclosure, the corresponding configuration relation between the data transmission parameters and the dual-carrier scheme can be set through the configuration condition of the dual-carrier scheme, and the corresponding configuration relation is used for describing the service requirement represented by the data transmission parameters and the corresponding relation between the service requirement and the dual-carrier scheme. The data transmission parameters describe performance characteristics of data transmission in the service, and service requirements of corresponding service can be determined according to the performance characteristics, so that a dual-carrier scheme suitable for the service requirements is determined, and then the corresponding dual-carrier scheme is configured in the service process, for example, a carrier aggregation scheme can be adopted for services with higher requirements on real-time performance, bandwidth capacity and the like, and a dual-connection scheme can be adopted for services with higher requirements on data transmission reliability.
It should be noted that, the above examples of the dual-carrier schemes and the characteristic descriptions of each dual-carrier scheme are only for illustration, and those skilled in the art may use other dual-carrier schemes or analyze other characteristics of the dual-carrier schemes according to actual application requirements, so as to determine the corresponding relationship between the dual-carrier schemes and different service requirements, which is not limited in particular by the embodiments of the present disclosure.
Fig. 2 is a second flowchart of steps of a dual carrier scheme configuration method according to an embodiment of the present disclosure. The method is applied to a base station, as shown in fig. 2, and may include the following steps 210 to 250.
Step 210, acquiring data transmission parameters in the service, where the data transmission parameters are used to characterize performance characteristics of data transmission in the service.
Step 210 may correspond to the related description of step 110, and is not repeated here.
Taking 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) as an example, a 5Qi (5G QoS Identifier,5GQuality of Service Identifier,5G quality of service identifier) parameter of a service can be acquired from a core network side at a base station, thereby acquiring a data transmission parameter of the service. The 5Qi parameter is a scalar for indexing the 5G QoS characteristics. The 5G QoS refers to a mechanism for allocating required network resources for each service to ensure end-to-end service quality under the condition that the network resources are limited by the 5G, so that the requirement of the service on the network resources can be determined through the 5Qi parameter, thereby configuring a dual carrier scheme corresponding to the service requirement.
In a method embodiment of the present disclosure, the 5Qi parameters may include Resource type, priority Level, packet Delay Budget, packet Error Rate, average window, maximum Data Burst Volume (maximum data burst size)
In a method embodiment of the present disclosure, if the data transmission parameter includes an upper packet delay limit, after step 210, the method further includes:
step 220, in the case that the upper limit of the data packet delay is less than or equal to the first threshold value, a carrier aggregation scheme is configured for the service.
The upper limit of the data packet delay is used to define the upper limit of the time delay of the data packet in transmission, and generally, when the time delay of the data packet exceeds the upper limit of the data packet delay, the data packet is considered to be lost, and the smaller the time delay value of the upper limit of the data packet delay, the higher the real-time requirement of the service on data transmission. Therefore, in case that the packet delay upper limit is less than or equal to the first threshold value in the 5Qi parameter of the service, a carrier aggregation scheme may be configured for the service.
In a method embodiment of the present disclosure, the first threshold may be set according to an actual network environment and service requirements, for example, the first threshold may be 500ms, which is not specifically limited in the present disclosure.
In an embodiment of the method of the present disclosure, the data transmission parameter further includes a resource utilization rate of a physical downlink control channel, and after step 220, further includes:
step 230, under the condition that the delay upper limit of the data packet is greater than the first threshold value and the resource utilization rate of the physical downlink control channel is greater than the second threshold value, configuring a carrier aggregation scheme for the service.
The physical downlink control channel (Physical Downlink Control Channel, PDCCH) is used for bearing downlink control information, including transmission format, downlink resource allocation, uplink scheduling permission, power control, uplink retransmission information and the like, and on the basis, the resource utilization rate of the physical downlink control channel characterizes the busyness of the control channel, thereby reflecting the service requirements in terms of bandwidth and capacity. And if the resource utilization rate of the physical downlink control channel is greater than the second threshold value, a carrier aggregation scheme can be configured for the service.
In a method embodiment of the present disclosure, the second threshold may be set according to an actual network environment and service requirements, for example, the second threshold may be 50%, which is not specifically limited by the present disclosure.
In a method embodiment of the present disclosure, the data transmission parameters further include a packet error rate, and after step 230, further includes:
step 240, when the data packet delay upper limit is greater than the first threshold, the resource utilization rate of the physical downlink control channel is less than or equal to the second threshold, and the data packet error rate is greater than or equal to the third threshold, a dual-connection scheme is configured for the service.
The data packet error rate refers to an upper limit of a data packet loss rate under a non-congestion condition, and specifically refers to an upper limit of a proportion of data packets which are normally processed and sent by a link layer protocol of a sender but not normally delivered to an upper layer by a receiver. On this basis, the packet error rate can characterize the traffic demand for data transmission reliability. On the basis of determining that the upper data packet delay is greater than the first threshold and the resource utilization of the physical limited control channel is less than or equal to the second threshold, it may be further determined whether the data packet error rate is greater than or equal to the third threshold. And under the condition that the error rate of the data packet is greater than or equal to a third threshold value, the data packet error rate indicates that the service requirement needs a PDCP (Packet Data Convergence Protocol ) copy function to ensure the reliability of data transmission, and the method is suitable for the shunt and asynchronous characteristics of a double-connection scheme, so that the double-connection scheme can be configured for the service.
Step 250, when the delay upper limit of the data packet is greater than the first threshold, the resource utilization rate of the physical downlink control channel is less than or equal to the second threshold, and the error rate of the data packet is less than the third threshold, a dual-connection scheme or a carrier aggregation scheme is configured for the service.
Under the condition that the error rate of the data packet is smaller than the third threshold value, the carrier aggregation scheme and the dual-connection scheme can be considered to meet the service requirement, so that the dual-connection scheme or the carrier aggregation scheme can be configured for the service.
In a method embodiment of the present disclosure, the third threshold may be set according to an actual network environment and service requirements, for example, the third threshold may be 99.9%, which is not specifically limited in the present disclosure.
Fig. 3 is a third flowchart of steps of a dual carrier scheme configuration method according to an embodiment of the present disclosure. The method is applied to a base station, as shown in fig. 3, and may include the following steps 310 to 320.
Step 310, acquiring data transmission parameters in the service, where the data transmission parameters are used to characterize performance characteristics of data transmission in the service.
Step 310 may correspond to the description of step 110 or step 210, and is not repeated here.
Step 320, according to the configuration condition of the dual carrier scheme, under the condition that the user equipment initiates random access in the service, the configuration parameters of the dual carrier scheme corresponding to the data transmission parameters are issued.
In the process of configuring a dual carrier scheme corresponding to the data transmission parameters for the service, the base station can issue the configuration parameters corresponding to the dual carrier scheme and perform a corresponding second carrier connection establishment procedure, for example, in the process of configuring the carrier aggregation scheme, when the user equipment initiates random access to perform RRC (Radio Resource Control ) reconfiguration, issue the RRC necessary system parameters of the carrier aggregation scheme, and then implement access of the user equipment based on the access procedure of the carrier aggregation scheme; in the process of configuring the dual-connection scheme, when the user equipment initiates random access to perform RRC reconfiguration, the necessary system parameters including SCG (Secondary Cell Group ) parameter configuration of the dual-connection scheme can be issued, and then the access of the user equipment is realized based on the access flow connection of the dual-connection scheme, wherein the dual-connection scheme requires the user equipment to initiate random access on a first carrier and a second carrier respectively.
