Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The present disclosure provides a communication method, described below in conjunction with fig. 1-2.
Fig. 1 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 1, the method of this embodiment includes: steps S102 to S112.
In step S102, the terminal establishes a connection with the base station and accesses one carrier.
The base station is a base station supporting sharing of multiple carriers. Each carrier belonging to a shared carrier may be provided by a different operator. The terminal may initiate random access to establish RRC (Radio Resource Control) connection with the base station, and access to one carrier. The procedures of random access and RRC connection establishment may be repeated with reference to the prior art.
In step S104, the base station obtains the capability information of the terminal, and correspondingly, the terminal reports the capability information to the base station.
The base station may send a UE Capability inquiry message to the terminal, and the terminal sends a UE Capability Information message to the base station to report Capability Information of the terminal. The capability information of the terminal includes, for example: an identification of whether the terminal supports the shared multiple carriers or the carriers supported by the terminal.
In step S106, when the terminal supports a plurality of shared carriers, the base station acquires the quality of service information of each carrier supported by the terminal.
The service quality information of each carrier supported by the terminal includes, for example: at least one of the number of terminals accessed by the carrier, the PRB utilization rate of the physical resource blocks of the carrier, the time delay information of each terminal accessed by the carrier, the received signal quality information of each terminal accessed by the carrier and the block error rate information of the carrier. The delay information of each terminal accessed by the carrier is, for example, an average delay of each terminal accessed by the carrier. The received signal quality information of each terminal of the carrier access is, for example, an average received signal quality of each terminal of the carrier access. The block error rate information of the carrier is, for example, an average block error rate of the carrier.
When the qos information of the carrier includes multiple items of information, different weights may be set for the items of information of the carrier, and the values of the items of information are weighted and summed according to the weights of the items of information to obtain the qos value of the carrier.
If the terminal only supports single carrier access, the connection of the currently accessed carrier is maintained, and the base station does not need to execute subsequent schemes.
In step S108, the base station generates resource indication information when the qos information of the carrier currently accessed by the terminal does not satisfy the preset condition and there are other carriers supported by the terminal whose qos information satisfies the preset condition.
In the case where the information on the quality of service of the carrier includes one item of information, the value of the quality of service of the carrier is determined based on the value of the one item of information. The information of the number of users, the PRB utilization rate, the time delay and the block error rate is inversely proportional to the service quality value, the higher the number of users, the PRB utilization rate, the time delay and the block error rate is, the lower the service quality value is, the quality of the received signal is proportional to the service quality value, and the higher the quality of the received signal is, the higher the service quality value is. A corresponding threshold may be set to determine whether the qos information of the carrier satisfies a preset condition. For example, the service quality information of the carrier includes PRB utilization of the carrier, a threshold of PRB utilization may be set, and if the PRB utilization of the carrier is greater than the threshold of PRB utilization, it is determined that the service quality of the carrier does not satisfy the preset condition. Under the condition that the service quality information of the carrier comprises a plurality of items of information, the method according to the embodiment determines the service quality value of the carrier, compares the service quality value with the corresponding service quality threshold value, and determines whether the service quality of the carrier meets the preset condition.
The base station may determine whether the service quality of each carrier supported by the terminal meets the preset condition by using the above method, and generate the resource indication information if the service quality information of the carrier currently accessed by the terminal does not meet the preset condition and there are other carriers supported by the terminal whose service quality information meets the preset condition. The resource indication information includes: congestion indication information of a carrier currently accessed by the terminal and indication information of available carriers. The Congestion Indication information of the Carrier currently accessed by the terminal may be referred to as Carrier Frequency Congestion Indication (CFCI), for example, and is used to indicate the Carrier currently accessed by the terminal. The indication information of the Available Carrier may be referred to as Available Carrier Frequency Band (ACFB) information, for example, and is used to indicate a Frequency Band of the Available Carrier.
The ACFB information may be determined according to the service quality of each carrier supported by the terminal, and the base station may select a carrier with the best service quality as an available carrier, and indicate the available carrier through the ACFB.
In some embodiments, if the base station is a base station supporting dual carrier sharing, and the terminal also supports shared dual carriers, in the case that the service quality information of the carrier currently accessed by the terminal does not satisfy the preset condition and the service quality information of another carrier satisfies the preset condition, the resource indication information sent by the base station may include only congestion indication information (CFCI) of the carrier currently accessed by the terminal. The terminal can know that the current accessed carrier is congested according to the CFCI, and another carrier is available.
In step S110, the base station sends resource indication information to the terminal, and accordingly, the terminal receives the resource indication information sent by the base station.
The base station sends the resource indication information to the terminal through the RRC Connection Reconfiguration message (RRC Connection Reconfiguration). And after receiving the RRC connection reconfiguration message, the terminal analyzes the congestion indication information of the carrier currently accessed by the terminal and the indication information of the available carrier.
In step S112, the terminal switches to an available carrier according to the resource indication information.
In the method of the embodiment, after the terminal is accessed, the base station determines whether the terminal supports multiple shared carriers according to the capability information of the terminal, if the terminal supports the multiple shared carriers, the service quality information of each carrier supported by the terminal is acquired, and when the service quality information of the carrier currently accessed by the terminal does not meet the preset condition, the terminal is instructed to switch to other available carriers, and the carrier of the low congestion frequency band is preferentially scheduled. The method of the embodiment can balance the resources of the shared carriers, effectively utilize the shared carriers, improve the resource utilization rate, reduce congestion, improve the service quality and improve the user experience.
Further embodiments of the communication method of the present disclosure are described below in conjunction with fig. 2.
Fig. 2 is a flow chart of some embodiments of the disclosed communication method. As shown in fig. 2, the method of this embodiment includes: steps S202 to S214.
In step S202, the terminal establishes a connection with the base station and accesses one carrier.
In step S204, the base station obtains the capability information of the terminal, and correspondingly, the terminal reports the capability information to the base station.
The capability information of the terminal includes: whether the terminal supports multiple carriers shared and whether the terminal performs (or supports) carrier aggregation.
In step S206, when the terminal supports multiple shared carriers and the terminal does not perform (or support) carrier aggregation, the base station acquires the qos information of each carrier supported by the terminal.
The resource indication information includes: congestion indication information of a carrier currently accessed by the terminal and indication information of available carriers.
In step S208, the base station generates resource indication information when the qos information of the carrier currently accessed by the terminal does not satisfy the preset condition and there is another carrier supported by the terminal whose qos information satisfies the preset condition.
In step S210, the base station sends resource indication information to the terminal, and accordingly, the terminal receives the resource indication information sent by the base station.
In step S212, the terminal switches to an available carrier according to the resource indication information.
In step S214, when the terminal supports multiple shared carriers and the terminal performs carrier aggregation, the base station allocates resources on each carrier to the terminal according to the qos information of each carrier supported by the terminal.
In some embodiments, the base station determines the quality of service values of the carriers supported by the terminal according to the method of the foregoing embodiment, and allocates resources on the carriers to the terminal according to the proportion of the quality of service values of the carriers. The higher the quality of service value of a carrier, the more resources are allocated on that carrier. The resources on each carrier can be allocated to the terminal in a fixed proportion, dynamic proportion and resource pool manner. In a fixed ratio manner, for example, the base station uses the ratio of the service quality values of the carriers determined for the first time as the ratio of the allocated resources of the carriers. And adopting a dynamic proportion mode, for example, the proportion of the service quality value of each carrier periodically determined by the base station is used as the proportion of the resource allocated to each carrier. The method of resource pool is adopted, for example, partial resources of each carrier are put into the resource pool, and under the condition that the service quality of one carrier connected with the terminal does not meet the preset condition, the resources of other carriers are selected from the resource pool and allocated to the terminal.
The method of the embodiment increases the judgment on whether the terminal performs carrier aggregation, and allocates the resources on each carrier according to the service quality of each carrier for the terminal performing carrier aggregation, so that the utilization rate of the resources is improved, congestion is reduced, the service quality is improved, and the user experience is improved.
