Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method, system, base station, and terminal. Background Art

[0002] Network sharing refers to the sharing of wireless networks between different operators, thereby reducing network construction investment. Currently, the main way for operators to build and share networks is MOCN (Multi-Operator Core Network), that is, one RAN (Radio Access Network) can be connected to multiple operator core network nodes, including independent carrier and shared carrier solutions.

[0003] When independent carriers are shared, each carrier is independently configured and managed. Logically independent carriers are used inside the wireless base station (gNodeB) to provide independent use to multiple operators. When shared carriers are shared, all RAN equipment on the base station side is shared, and different operators share the same carrier.

[0004] In the shared carrier scenario, multiple operators provide carriers of different frequency bands to share multiple carriers. This is a solution. Some existing terminals may only support access to the frequency band shared by one operator, but not the frequency bands shared by other operators. New terminals can support cross-band access, that is, support multiple shared carriers, and can access both the frequency bands shared by one operator and the frequency bands shared by other operators.

[0034] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] The present disclosure provides a communication method, Figure 1-2 Give a description.

[0036] Figure 1 Flowcharts of some embodiments of the communication method disclosed herein. Figure 1 As shown, the method of this embodiment includes: steps S102 to S112.

[0037] In step S102, the terminal establishes a connection with a base station and accesses a carrier.

[0038] The base station is a base station that supports multiple carrier sharing. Each carrier is a shared carrier and can be provided by different operators. The terminal can initiate random access to establish an RRC (Radio Resource Control) connection with the base station and access a carrier. The process of random access and RRC connection establishment can refer to the prior art and will not be repeated.

[0039] In step S104, the base station obtains the capability information of the terminal, and accordingly, the terminal reports the capability information to the base station.

[0040] The base station may send a UE Capability Enquiry message to the terminal, and the terminal may send a UE Capability Information message to the base station to report its own capability information. The capability information of the terminal may include, for example, whether the terminal supports multiple shared carriers or identifiers of carriers supported by the terminal.

[0041] In step S106, when the terminal supports multiple shared carriers, the base station obtains service quality information of each carrier supported by the terminal.

[0042] The service quality information of each carrier supported by the terminal includes, for example, at least one of the following: the number of terminals accessed by the carrier, the utilization rate of the physical resource block (PRB) of the carrier, the 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, the average delay of each terminal accessed by the carrier. The received signal quality information of each terminal accessed by the carrier is, for example, the average received signal quality of each terminal accessed by the carrier. The block error rate information of the carrier is, for example, the average block error rate of the carrier.

[0043] When the service quality information of a carrier includes multiple pieces of information, different weights may be set for each piece of information of the carrier, and the value of each piece of information may be weighted and summed according to the weight of each piece of information to obtain the service quality value of the carrier.

[0044] 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 solutions.

[0045] In step S108, the base station generates resource indication information when 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.

[0046] In the case where the service quality information of the carrier includes one item of information, the service quality value of the carrier is determined according to the value of the information. The number of users, PRB utilization, delay, and block error rate information are inversely proportional to the service quality value. The higher the number of users, PRB utilization, delay, and block error rate, the lower the service quality value. The received signal quality is proportional to the service quality value. The higher the received signal quality, the higher the service quality value. A corresponding threshold can be set to determine whether the service quality information of the carrier meets the preset conditions. For example, the service quality information of the carrier includes the PRB utilization of the carrier, and a PRB utilization threshold can be set. If the PRB utilization of the carrier is greater than the PRB utilization threshold, it is determined that the service quality of the carrier does not meet the preset conditions. In the case where the service quality information of the carrier includes multiple items of information, the service quality value of the carrier is determined according to the method of the above embodiment, and compared with the corresponding service quality threshold to determine whether the service quality of the carrier meets the preset conditions.

[0047] The base station can use the above method to determine whether the service quality of each carrier supported by the terminal meets the preset conditions. If the service quality information of the carrier currently accessed by the terminal does not meet the preset conditions, and there are other carriers supported by the terminal whose service quality information meets the preset conditions, resource indication information is generated. The resource indication information includes: congestion indication information of the carrier currently accessed by the terminal and indication information of available carriers. The congestion indication information of the carrier currently accessed by the terminal can be called, for example, a carrier frequency congestion indication (Carrier Frequency Congestion Indication, CFCI), which is used to indicate the carrier currently accessed by the terminal. The indication information of the available carrier can be called, for example, available carrier frequency band (Available Carrier Frequency Band, ACFB) information, which is used to indicate the frequency band of the available carrier.

[0048] The ACFB information may be determined according to the service quality of each carrier supported by the terminal. The base station may select the carrier with the best service quality as the available carrier and indicate the available carrier through ACFB.

[0049] In some embodiments, if the base station is a base station supporting dual-carrier sharing, and the terminal also supports shared dual carriers, when the service quality information of the carrier currently accessed by the terminal does not meet the preset conditions and the service quality information of another carrier meets the preset conditions, the resource indication information sent by the base station may only include the congestion indication information (CFCI) of the carrier currently accessed by the terminal. The terminal can know from the CFCI that the currently accessed carrier is congested, and the other carrier is available.

[0050] In step S110, the base station sends resource indication information to the terminal, and correspondingly, the terminal receives the resource indication information sent by the base station.

[0051] The base station sends the resource indication information to the terminal via an RRC connection reconfiguration message (RRC Connection Reconfiguration). After receiving the RRC connection reconfiguration message, the terminal parses and obtains the congestion indication information of the carrier currently accessed by the terminal and the indication information of the available carrier.

[0052] In step S112, the terminal switches to an available carrier according to the resource indication information.

[0053] In the method of the above embodiment, after the terminal accesses, the base station determines whether the terminal supports multiple shared carriers based on the terminal's capability information. If the terminal supports multiple shared carriers, the service quality information of each carrier supported by the terminal is obtained, and if the service quality information of the carrier currently accessed by the terminal does not meet the preset conditions, the terminal is instructed to switch to other available carriers, and preferentially schedule to carriers in low congestion frequency bands. The method of the above embodiment can balance the resources of each shared carrier, effectively utilize multiple shared carriers, improve resource utilization, reduce congestion, and improve service quality and user experience.

[0054] Combine the following Figure 2 Other embodiments of the communication method disclosed herein are described.

[0055] Figure 2 Flowcharts of some embodiments of the communication method disclosed herein. Figure 2 As shown, the method of this embodiment includes: steps S202 to S214.

[0056] In step S202, the terminal establishes a connection with a base station and accesses a carrier.

[0057] 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.

[0058] The capability information of the terminal includes: whether the terminal supports multiple shared carriers and whether the terminal performs (or supports) carrier aggregation.

[0059] In step S206, when the terminal supports multiple shared carriers and the terminal does not perform (or supports) carrier aggregation, the base station obtains service quality information of each carrier supported by the terminal.

[0060] The resource indication information includes: congestion indication information of the carrier currently accessed by the terminal and indication information of available carriers.

[0061] In step S208, the base station generates resource indication information when 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.

[0062] In step S210, the base station sends resource indication information to the terminal, and correspondingly, the terminal receives the resource indication information sent by the base station.

[0063] In step S212, the terminal switches to an available carrier according to the resource indication information.

[0064] 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 service quality information of each carrier supported by the terminal.

[0065] In some embodiments, the base station determines the service quality value of each carrier supported by the terminal according to the method of the foregoing embodiment, and allocates resources on each carrier to the terminal according to the ratio of the service quality value of each carrier. The higher the service quality value of the carrier, the more resources are allocated on the carrier. The resources on each carrier can be allocated to the terminal in a fixed ratio, a dynamic ratio and a resource pool. For example, in the case of a fixed ratio, the base station uses the ratio of the service quality values ​​of each carrier determined for the first time as the ratio of resources allocated to each carrier. In the case of a dynamic ratio, for example, the base station periodically determines the ratio of the service quality values ​​of each carrier as the ratio of resources allocated to each carrier. In the case of a resource pool, for example, part of the resources of each carrier are placed in a resource pool, and when the service quality of a carrier to which the terminal is connected does not meet the preset conditions, the resources of other carriers are selected from the resource pool and allocated to the terminal.

[0066] The method of the above embodiment adds a judgment on whether the terminal performs carrier aggregation. For the terminal performing carrier aggregation, resources on each carrier are allocated according to the service quality of each carrier, thereby improving resource utilization, reducing congestion, improving service quality and enhancing user experience.
