technical field

Background technique

Network sharing refers to the sharing of wireless networks among different operators, thereby reducing investment in network construction. At present, the main method of network co-construction and sharing among operators is MOCN (Multi-Operator Core Network, multi-operator core network), that is, one RAN (Radio Access Network, radio access network) can be connected to multiple operators' core networks Nodes, including the base station (gNodeB), adopt two schemes of independent carrier and shared carrier.

When the base station adopts independent carriers, each carrier is independently configured and managed. Inside the base station on the radio side, different logically independent carriers are provided to multiple operators for independent use. When the base station adopts the shared carrier, the RAN equipment on the base station side is fully shared, and different operators share the same carrier.

In a scenario where a base station adopts a shared carrier, it is a solution that multiple operators provide carriers of different frequency bands to realize the sharing of multiple carriers. Some existing terminals may only support access to the frequency band shared by one operator, but not the frequency band shared by other operators. The new terminal can support cross-band access, that is, the new terminal supports multiple carriers shared, and can access the frequency band shared by one operator or the frequency band shared by other operators.

Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but 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 in any way. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

The inventors found that in the scenario where the base station adopts a shared carrier, that is, multiple carriers are shared, there are different types of terminals, some terminals can only access one carrier, and some terminals can access multiple carriers. Currently, there is no strategy for scheduling and resource allocation for different terminals, which may lead to an excessive number of access terminals on some carriers, overloading and causing congestion and poor service quality, resulting in resource congestion and waste.

A technical problem to be solved by the present disclosure is: how to effectively utilize multiple shared carriers, improve resource utilization, and reduce congestion.

The present disclosure provides a communication method, which will be described below with reference to FIGS. 1 to 2 .

FIG. 1 is a flowchart of some embodiments of the disclosed communication method. As shown in FIG. 1, the method of this embodiment includes steps S102-S112.

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

The base station is a base station that supports multiple carrier sharing. Each of the multiple carriers belongs to a shared carrier and can be provided by different operators. The terminal can initiate random access to establish an RRC (Radio Resource Control, radio resource control) connection with the base station, and access a carrier. The processes of random access and RRC connection establishment may be described with reference to the prior art and will not be repeated.

In step S104, the base station acquires capability information of the terminal, and accordingly, the terminal reports the capability information to the base station.

The base station may send a UE Capability Enquiry (UE capability inquiry) message to the terminal, and the terminal may send a UE Capability Information (UE capability information) message to the base station to report its own capability information. The capability information of the terminal includes, for example, information on whether the terminal supports multiple shared carriers or an identifier of a carrier supported by the terminal. If the terminal supports the shared multiple carriers, the shared multiple carriers supported by the terminal include part or all of the multiple carriers shared by the base station.

In step S106, when the terminal supports multiple shared carriers, the base station acquires service quality information of each of the multiple carriers supported by the terminal.

The service quality information of each carrier in the multiple carriers supported by the terminal includes, for example: the number of terminals accessed by each carrier in the multiple carriers supported by the terminal, the physical resource block PRB utilization rate of each carrier in the multiple carriers supported by the terminal, and the number of terminals supported by the terminal. The delay information of each terminal accessed by each carrier among the multiple carriers supported by the terminal, the received signal quality information of each terminal accessed by each carrier among the multiple carriers supported by the terminal, and the block error rate of each carrier among the multiple carriers supported by the terminal at least one of the information. For each carrier in the multiple carriers supported by the terminal, 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.

For each carrier among the multiple carriers supported by the terminal, when the quality of service information of the carrier includes multiple pieces of information, different weights can be set for the various pieces of information of the carrier, and each piece of information can be evaluated according to the weight of the pieces of information. The value of the carrier is weighted and summed to obtain the quality of service 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 perform subsequent solutions.

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.

For each carrier among the multiple carriers supported by the terminal, if the QoS information of the carrier includes an item of information, the QoS value of the carrier is determined according to the value of the item of information. The number of users (number of terminals), PRB utilization, delay, and block error rate are inversely proportional to the QoS value. The higher the number of users (terminals), PRB utilization, delay, and block error rate, the higher the quality of service. The lower the value is, the received signal quality information is proportional to the QoS value, and the higher the received signal quality, the higher the QoS value. A corresponding threshold may be set to determine whether the quality of service information of the carrier satisfies the preset condition. For example, for each carrier among multiple carriers supported by the terminal, the service quality information of the carrier includes the PRB utilization rate 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, then determine the The quality of service of the carrier does not meet the preset conditions. For each carrier in the multiple carriers supported by the terminal, in the case that the QoS information of the carrier includes multiple pieces of information, the QoS value of the carrier is determined according to the method of the above embodiment, and the QoS value of the carrier is compared with the corresponding QoS threshold value to determine Whether the quality of service of the carrier satisfies the preset condition.

The base station can use the above method to determine whether the quality of service of each carrier in the multiple carriers supported by the terminal meets the preset conditions. Other carriers supported by the terminal generate resource indication information. The resource indication information includes: congestion indication information of a carrier currently accessed by the terminal and indication information of an available carrier. The congestion indication information of the carrier currently accessed by the terminal may be called, for example, a carrier frequency congestion indication (Carrier Frequency Congestion Indication, CFCI), which is used to indicate the congestion (unavailable) of the carrier currently accessed by the terminal. The indication information of the available carriers may be called, for example, available carrier frequency band (Available Carrier Frequency Band, ACFB) information, which is used to indicate the frequency bands of the available carriers.

The ACFB information can be determined according to the service quality of each carrier among the multiple carriers supported by the terminal, and the base station can select the carrier with the best service quality as the available carrier, and indicate the available carrier through ACFB.

In some embodiments, if the base station is a base station that supports dual-carrier sharing, and the terminal also supports shared dual-carriers, the quality of service information of the carrier currently accessed by the terminal does not meet the preset conditions and the quality of service information of another carrier meets the preset conditions. If the conditions are set, 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. According to the CFCI, the terminal can know that the currently accessed carrier is congested, but another carrier is available.

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.

The base station sends the resource indication information to the terminal through an RRC connection reconfiguration message (RRC Connection Reconfiguration). After the terminal receives the RRC connection reconfiguration message, it parses and obtains 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 above embodiment, after the terminal accesses, the base station determines whether the terminal supports the shared multiple carriers according to the capability information of the terminal, and if the terminal supports the shared multiple carriers, obtains the service quality information of each carrier supported by the terminal, and When the quality of service 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 the terminal is preferentially scheduled to a carrier in a low-congested frequency band. The methods of the above embodiments can balance the resources of the shared carriers, effectively utilize the shared multiple carriers, improve resource utilization, reduce congestion, and improve service quality and improve user experience.

Other embodiments of the communication method of the present disclosure will be described below with reference to FIG. 2 .

FIG. 2 is a flowchart of some embodiments of the disclosed communication method. As shown in FIG. 2, the method of this embodiment includes steps S202-S214.

The capability information of the terminal includes: information on whether the terminal supports multiple shared carriers and information on 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 does not support) carrier aggregation, the base station acquires service quality information of each carrier among the multiple carriers supported by the terminal. This step S206 may be replaced by step S106.

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. In the case where step S206 is replaced by step S106, step S208 may be replaced by the base station not performing (or not supporting) carrier aggregation at the terminal, the quality of service information of the carrier currently accessed by the terminal does not meet the preset conditions, and there is a quality of service In the case of other carriers supported by the terminal whose information satisfies the preset condition, the resource indication information is generated.

The resource indication information includes: congestion indication information of a carrier currently accessed by the terminal and indication information of an available carrier.

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 carriers shared by the terminal, and the terminal performs (or supports) carrier aggregation, the base station allocates the multiple carriers supported by the terminal to the terminal according to the service quality information of each carrier among the multiple carriers supported by the terminal. resources on each of the carriers. Correspondingly, the terminal acquires resource information on each of the multiple carriers allocated by the base station to the terminal and supported by the terminal. Step S214 may be performed in parallel with step S206 or step S106.

In some embodiments, the base station determines the quality of service value of each carrier in the multiple carriers supported by the terminal according to the method in the foregoing embodiment, and allocates resources on each carrier to the terminal according to the ratio of the quality of service value of each carrier in the multiple carriers. . For each carrier among the multiple carriers supported by the terminal, the higher the QoS value of the carrier is, the more resources are allocated on the carrier. The terminal may be allocated resources on each of the multiple carriers in the manner of a fixed ratio, a dynamic ratio or a resource pool. In a fixed ratio manner, for example, the base station uses the ratio of the quality of service value of each carrier in the multiple carriers determined for the first time as the ratio of resources allocated to each carrier in the multiple carriers. In a dynamic ratio manner, for example, the base station periodically determines the ratio of the quality of service value of each carrier among the multiple carriers as the ratio of resources allocated to each carrier. Using the resource pool method, for example, part of the resources of each carrier in the multiple carriers is put into the resource pool, and when the service quality of one carrier connected to the terminal does not meet the preset conditions, the resource allocation of other carriers is selected from the resource pool. to the terminal.

The method of the above embodiment increases the judgment on whether the terminal performs carrier aggregation, and allocates resources on each carrier according to the service quality of each carrier for the terminal performing carrier aggregation, which improves the utilization rate of resources, reduces congestion, and improves service quality and improves users. experience.
