The method for determining the auxiliary carrier wave is applied to a scene that a terminal processes a service which utilizes the carrier wave and has a high uplink PRB utilization rate. In the related art, when a terminal processes a service with a high uplink PRB utilization rate using a carrier, an auxiliary carrier may be added, so that the terminal may operate two carriers at the same time to complete processing of the service.
It should be noted that, in the above technical solution, the terminal may complete processing of a service with a high uplink PRB utilization rate using a carrier through a Supplemental Uplink (SUL) function. Or, the terminal may complete processing of a service with a high uplink PRB utilization rate using a Carrier by an uplink Carrier Aggregation (UL CA) function. Alternatively, the terminal may complete processing of a traffic with a large uplink PRB utilization rate using a carrier by an uplink Transmit Switching (UL Tx Switching) function.
Illustratively, the availability of the uplink PRB for the primary carrier used by the terminal is 0.3. If the uplink PRB utilization rate of the carrier used by service a is 0.3, the terminal may use the primary carrier to complete processing on service a. If the uplink PRB utilization rate of the carrier used by the service B is 0.5, when the terminal processes the service B, it needs to add an auxiliary carrier to the terminal through the uplink transmission switching function, so that the terminal can operate the main carrier and the auxiliary carrier at the same time to complete processing of the service B.
The operation mode of the terminal having two antennas will be described with reference to table 1. The operation mode of the terminal with two antennas comprises: case 1 (i.e. mode 1) and Case 2 (i.e. mode 2), the number of antenna transmission Transmit (Tx) corresponding to Case 1 is 1Tx on carrier 1and1Tx on carrier2, and the number of uplink transmission antenna ports Port (P) corresponding to Case 1 includes: the number of antennas Tx corresponding to 1P +0P, 1P +1P and 0P +1P, and case 2 is 0Tx on carrier 1and 2Tx on carrier2, and the number of uplink transmission antennas P corresponding to case 2 includes: 0P +2P and 0P +1P. Wherein 1Tx on carrier 1and1Tx on carrier2 is used for indicating that one antenna can transmit carrier 1, the other antenna can transmit carrier2, 0Tx on carrier 1and 2Tx on carrier2 is used for indicating that one antenna does not transmit carrier, the other antenna can transmit carrier 1and carrier2, 1P + 10P is used for indicating that one antenna transmits carrier 1, the other antenna does not transmit carrier2, 1P +1P is used for indicating that one antenna transmits carrier 1, the other antenna transmits carrier2, 0P +1P is used for indicating that one antenna does not transmit carrier 1, the other antenna transmits carrier2, 0P +2P, the one antenna does not transmit carrier, and the other antenna transmits carrier 1and carrier2.

Wherein, case 1 can be divided into two working modes of option 1and option 2 according to whether the service data supports parallel transmission on two uplink carriers.
The operation mode of Case 1 will be described with reference to table 2. The working modes of Case 1 include: the data transmission condition corresponding to the Case 1option 1and the Case 1option 2, and the Case 1option 1 does not support concurrency, and the number of ports (P) of the uplink transmission antenna corresponding to the Case 1option 1 includes: the data transmission conditions corresponding to 1P +, 0P +1P and Case 1operation 2 support concurrency, and the number of uplink transmission antennas P corresponding to Case 1operation 2 includes: 1P +0P, 1P +1P and 0P +1P.

The operation mode of the transmission switching function of the uplink will be described below in conjunction with the operation mode of the terminal having two antennas. The operation mode of the transmission switching function of the uplink includes: a switched UL (switched UL) and a concurrent UL (dual UL).
As shown in fig. 1, in the Case that the operation mode of the terminal with two antennas is Case 1option 1 (or 0p +1p in Case 2), the terminal can complete transmission of traffic data through switched UL. Wherein, the carrier 1 is a Time Division Duplex (TDD) carrier, the carrier2 is a Frequency Division Duplex (FDD) carrier, D is used for indicating a downlink pilot, U is used for indicating an uplink pilot, and S is used for indicating a special subframe.

Wherein, the carrier 1 is a Time Division Duplex (TDD) carrier, the carrier2 is a Frequency Division Duplex (FDD) carrier, D is used for indicating a downlink pilot, U is used for indicating an uplink pilot, and S is used for indicating a special subframe.
However, in the current technical solution, when the terminal adds the secondary carrier, the availability of the uplink PRB of the secondary carrier may be low, which results in low efficiency for the terminal to process the service by using the secondary carrier, and affects the use experience of the user for using the service.
In order to solve the above problem, an embodiment of the present application provides a method for determining an auxiliary carrier, where a network device may obtain a target signal strength, a network load amount, bandwidth information, and frequency information of each of a plurality of auxiliary carriers, where the target signal strength is a signal strength of an auxiliary carrier measured by a target terminal.

Then, the network device may determine a target secondary carrier according to the target signal strength, the network load amount, and the priority value of each secondary carrier, where the target secondary carrier is a secondary carrier with the highest target signal strength, the lowest network load amount, and the highest priority among the multiple secondary carriers. That is, the network device may use, as the target secondary carrier, a secondary carrier having the highest target signal strength, the lowest network load amount, and the highest priority among the plurality of secondary carriers. Therefore, the network equipment can indicate the target terminal to add the target auxiliary carrier, the efficiency of the target terminal for processing the service by using the target auxiliary carrier is improved, and the service using experience of a user is guaranteed.

In some embodiments, the server stores preset priority information corresponding to each of the plurality of operator identifiers.
It should be noted that, in the embodiment of the present application, the operator identifier is not limited. For example, the operator identification may be an Identity Document (ID) of the operator. Also for example, the operator identity may be an identity of a Public Land Mobile Network (PLMN) used by the operator. Also for example, the operator identity may be a Mobile Network Code (MNC) of the operator in the PLMN.

In a possible implementation manner, the server may store an operator identifier corresponding to the primary carrier used by the target terminal.
In another possible implementation manner, the server may receive an operator identifier corresponding to the primary carrier from the target terminal.
In a possible design, before the server determines the priority value of each third secondary carrier, the server may select, according to the operator identifier corresponding to the primary carrier used by the target terminal, preset priority information corresponding to the operator identifier corresponding to the primary carrier used by the target terminal from the preset priority information corresponding to the multiple operator identifiers.
Illustratively, preset priority information corresponding to 46001 and preset priority information corresponding to 46011 shown in table 4 and table 5 are combined. If the operator identifier corresponding to the primary carrier used by the target terminal is 46001, the server determines that the preset priority information corresponding to the operator identifier corresponding to the primary carrier used by the target terminal is the preset priority information corresponding to 46001 shown in table 4.
It can be understood that the server may select, according to the operator identifier corresponding to the used primary carrier of the target terminal, the preset priority information corresponding to the operator identifier corresponding to the primary carrier used by the target terminal from the preset priority information corresponding to the multiple operator identifiers. That is to say, the server may determine the preset priority information corresponding to the operator identifier corresponding to the primary carrier used by the target terminal. Therefore, the accuracy of the preset priority information can be improved, and the accuracy of the priority value of each auxiliary carrier is further improved.
S503, the server takes the auxiliary carrier with the priority value meeting the preset priority condition in at least one third auxiliary carrier as a second auxiliary carrier.
It should be noted that, in the embodiment of the present application, the preset priority condition is not limited, for example, the preset priority condition may be a secondary carrier with a maximum priority value in at least one third secondary carrier. For another example, the preset priority condition may be a secondary carrier with a minimum priority value among the at least one third secondary carrier. For another example, the preset priority condition may be a secondary carrier of the at least one third secondary carrier having a priority value greater than a preset priority threshold.
Illustratively, the at least one third secondary carrier includes: the carrier system comprises a carrier A, a carrier B, a carrier C and a carrier D, wherein the priority value of the carrier A is 5, the priority value of the carrier B is 7, the priority value of the carrier C is 3, and the priority value of the carrier D is 7. And if the preset priority condition is the auxiliary carrier with the maximum priority value in the at least one third auxiliary carrier, the server respectively takes the carrier B and the carrier D as a second auxiliary carrier. If the preset priority condition is that the priority value of the at least one third auxiliary carrier is greater than 3 (namely the preset priority threshold), the server respectively takes the carrier A, the carrier B and the carrier D as a second auxiliary carrier.
It can be understood that, according to the preset signal strength threshold, the first preset network load threshold, the target signal strength of each first auxiliary carrier, and the network load amount, the server may use, as the third auxiliary carrier, an auxiliary carrier, of which the target signal strength is greater than the preset signal strength threshold and the network load amount is less than the first preset network load threshold, among the multiple first auxiliary carriers. And the network device may determine the priority value of each third auxiliary carrier according to the preset priority information and the bandwidth information and frequency information of each third auxiliary carrier. Then, the server may use, as the second auxiliary carrier, an auxiliary carrier whose priority value satisfies a preset priority condition among the at least one third auxiliary carrier according to the preset priority condition and the priority value of each third auxiliary carrier. That is to say, the target signal strength of each second auxiliary carrier is greater than the preset signal strength threshold, the network load amount is less than the first preset network load threshold, and the priority value meets the preset priority condition. Therefore, the accuracy of the target auxiliary carrier can be improved, the efficiency of the terminal for processing the service by using the target auxiliary carrier is further improved, and the service using experience of the user is guaranteed.
In some embodiments, the server may determine the target secondary carrier according to a priority value of each of the at least one second secondary carrier.
As shown in fig. 6, in the method for determining the secondary carrier, S403 may include S601-S603.
S601, the server determines whether a difference between a network load amount of the first carrier and a network load amount of the second carrier is greater than a second preset network load threshold.
Wherein the at least one second secondary carrier may include: the carrier system comprises a first carrier and a second carrier, wherein the first carrier is an auxiliary carrier with the maximum priority value in at least one third auxiliary carrier, and the second carrier is an auxiliary carrier with the maximum priority value in the auxiliary carriers except the first carrier in the at least one third auxiliary carrier.
Illustratively, the at least one second secondary carrier includes: the carrier system comprises a carrier A, a carrier B and a carrier C, wherein the priority value of the carrier A is 7, the priority value of the carrier B is 4, the priority value of the carrier C is 2, and then the first carrier is the carrier A, and the second carrier is the carrier B.
In one possible implementation, the server stores a second preset network load threshold. The server may determine whether a difference between the network load of the first carrier and the network load of the second carrier is greater than a second preset network load threshold according to the network load of the first carrier, the network load of the second carrier, and the second preset network load threshold. If the server determines that the difference between the network load amount of the first carrier and the network load amount of the second carrier is less than the second preset network load threshold, the server performs S602. If the server determines that the difference between the network load amount of the first carrier and the network load amount of the second carrier is greater than the second preset network load threshold, the server performs S603.
Illustratively, the server stores a second preset network load threshold of 0.1. If the network load of the first carrier is 0.5 and the network load of the second carrier is 0.45, the server determines that a difference between the network load of the first carrier and the network load of the second carrier is less than a second preset network load threshold, and the server performs S602. If the network load of the first carrier is 0.4 and the network load of the second carrier is 0.65, the server determines that the difference between the network load of the first carrier and the network load of the second carrier is greater than a second preset network load threshold, and the server performs S603.
S602, the server takes the first carrier as a target secondary carrier.
In this embodiment of the application, when a difference between a network load amount of a first carrier and a network load amount of a second carrier is smaller than a second preset network load threshold, a server takes an auxiliary carrier with a maximum priority value in the first carrier and the second carrier as a target auxiliary carrier. That is, the server takes the first secondary carrier as the target secondary carrier when the difference between the network load amount of the first carrier and the network load amount of the second carrier is smaller than the second preset network load threshold.
For example, in a case that a difference between a network load amount of the first carrier and a network load amount of the second carrier is smaller than a second preset network load threshold, a priority value of the first carrier is 5, and a priority value of the second carrier is 4, the server regards the first carrier as the target secondary carrier.
In some embodiments, in a case that a difference between a network load amount of the first carrier and a network load amount of the second carrier is smaller than a second preset network load threshold, if the priority value of the first carrier is the same as the priority value of the second carrier, the server takes the secondary carrier with the highest target signal strength in the first carrier and the second carrier as the target secondary carrier.
For example, in a case that a difference between a network load amount of the first carrier and a network load amount of the second carrier is smaller than a second preset network load threshold, if a priority value of the first carrier is 5 and a target signal strength is 11, and a priority value of the second carrier is 5 and a target signal strength is 8, the server regards the first carrier as the target secondary carrier.
It may be understood that, in a case that a difference between a network load amount of the first carrier and a network load amount of the second carrier is smaller than a second preset network load threshold, and a priority value of the first carrier is the same as a priority value of the second carrier, the server may use a secondary carrier with a maximum target signal strength in the first carrier and the second carrier as the target secondary carrier. That is, the target secondary carrier is the secondary carrier with the highest priority value and the highest target signal strength among the first carrier and the second carrier. Therefore, the accuracy of the target auxiliary carrier can be improved, the efficiency of the terminal for processing the service by using the target auxiliary carrier is further improved, and the service using experience of a user is guaranteed.
S603, the server takes the auxiliary carrier with the minimum network load in the first carrier and the second carrier as a target auxiliary carrier.
Illustratively, the network load of the first carrier is 0.22, and the network load of the second carrier is 0.21, the server takes the second carrier as the target secondary carrier.
It should be noted that, if the difference between the network load amount of the first carrier and the network load amount of the second carrier is equal to the second preset network load threshold, the server may execute any one of the steps S602 and S603.
It is to be understood that the server may determine, according to the priority value of each of the at least one second secondary carrier, a first carrier and a second carrier, where the first carrier is a secondary carrier with a highest priority value among the at least one third secondary carrier, and the second carrier is a secondary carrier with a highest priority value among secondary carriers other than the first carrier among the at least one third secondary carrier. Moreover, the server may determine whether a difference value between the network load of the first carrier and the network load of the second carrier is greater than a second preset network load threshold according to the network load of the first carrier, the network load of the second carrier, and the second preset network load threshold. And if the difference value between the network load quantity of the first carrier and the network load quantity of the second carrier is smaller than a second preset network load threshold value, the server takes the first carrier as a target auxiliary carrier. And if the difference value between the network load capacity of the first carrier and the network load capacity of the second carrier is greater than a second preset network load threshold value, taking the auxiliary carrier with the minimum network load capacity in the first carrier and the second carrier of the server as a target auxiliary carrier. Therefore, the accuracy of the target auxiliary carrier can be improved, the efficiency of the terminal for processing the service by using the target auxiliary carrier is further improved, and the service using experience of a user is guaranteed.
In some embodiments, the server may instruct the target terminal to enable the uplink transmission handover function before the server obtains the target signal strength and the network resource information for each of the plurality of first secondary carriers.
As shown in fig. 7, before performing S401, the method for determining the secondary carrier may further include S701-S706.
S701, the server receives first information from the target terminal.
Wherein the first information is used for indicating that the uplink transmission switching function is supported.
S702, the server updates the target number.
The target number is the number of terminals accessing the primary carrier and supporting the uplink transmission switching function.
Illustratively, the target number of server stores is 2. And if the server determines that the target terminal accesses the main carrier and supports the transmission switching function of the uplink, the server updates the target number to 3.
S703, the server acquires the network load of the main carrier.
In one possible implementation, the server may receive a network load amount of a primary carrier from a base station corresponding to the primary carrier.
In another possible implementation manner, the server stores a network load amount of a main carrier of the base station corresponding to the main carrier.
It should be noted that, in the embodiment of the present application, the order of executing S702 and S703 is not limited. For example, the server may perform S702 first and then S703. For another example, the server may perform S703 first and then S702. For another example, the server may simultaneously perform S702 and S703.
S704, the server determines whether the updated target number is larger than a first preset number threshold value.
In one possible implementation, the server stores a first preset number threshold. The server may determine whether the updated target number is greater than a first preset number threshold according to the updated target number and the first preset number threshold. If the server determines that the updated target number is greater than the first preset number threshold, the server performs S705.
Illustratively, the first preset number threshold stored by the server is 7. If the updated target number stored by the server is 8, the server determines that the updated target number is greater than the first preset number threshold, and the server performs S705.
S705, the server determines whether a network load of the primary carrier is greater than a third preset network load threshold.
In one possible implementation, the server stores a third preset network load threshold. The server may determine whether the network load amount of the main carrier is greater than a third preset network load threshold according to the network load amount of the main carrier and the third preset network load threshold. If the server determines that the network load amount of the primary carrier is greater than the third preset network load threshold, the server performs S706.
In one possible design, the server may determine the third preset network load threshold according to the fourth preset network load threshold, the preset network load coefficient, and the target number.
The third preset network load threshold may be represented by formula one.
L = X-N × Y formula one.
Wherein, L is used for representing a third preset network load threshold, X is used for representing a fourth network load threshold, N is used for representing a target number, and Y is used for representing a preset network load coefficient.
Illustratively, the fourth network load threshold is 0.4, and the preset network load factor is 0.05. If the target number is 2, the third predetermined network load threshold is 0.3.
Next, the server determines whether the network load of the main carrier is greater than a third preset network load threshold according to the network load of the main carrier and the third preset network load threshold.
Illustratively, the third preset network load threshold stored by the server is 7. If the updated target number stored by the server is 8, the server determines that the updated target number is greater than the first preset number threshold, and the server performs S705.
It should be noted that, in the embodiment of the present application, the order of executing S705 and S706 is not limited. For example, the server may perform S705 first and then S706. For another example, the server may perform S706 first and then S705. For another example, the server may simultaneously perform S705 and S706.
S706, the server sends a first indication message to the target terminal.
The first indication message is used for indicating the target terminal to enable the uplink transmission switching function.
It is understood that the server may determine whether the target number is greater than the first preset number threshold and the network load amount of the main carrier is greater than the third preset network load threshold according to the third preset network load threshold, the first preset number threshold, the target number, and the network load amount of the main carrier. The server may send a first indication message to the target terminal, where the first indication message is used to indicate the target terminal to enable the uplink sending and switching function, when the target number is greater than the first preset number threshold and the network load amount of the primary carrier is greater than the third preset network load threshold. That is, the server may control whether the target terminal enables the transmission switching function of the uplink according to the third preset network load threshold, the first preset number threshold, the target number, and the network load amount of the primary carrier. In this way, management of the uplink transmission switching function of the terminal can be achieved, and power consumption of the terminal enabling the uplink transmission switching function can be reduced.
In some embodiments, the server stores a second preset number threshold. After the server determines that the updated target number is greater than the first preset number threshold and the network load amount of the primary carrier is greater than the third preset network load threshold, the server may determine whether the updated target number is greater than the second preset number threshold according to the stored updated target number and the second preset number threshold. And if the updated target number is larger than a second preset number threshold, the server sends a second indication message to the target terminal.
And the second indication message is used for indicating the target terminal to enable the uplink transmission switching function in a preset time period.
Illustratively, the server stores a second preset number threshold of 10. If the updated target number stored by the server is 11, the server determines that the updated target number is greater than a second preset number threshold, and sends a second indication message to the target terminal, where the second indication message indicates that the target terminal enables the uplink transmission switching function at 8 am to 10 am (i.e., a preset time period).
It can be understood that the server may send a second indication message to the target terminal when the target number is greater than the first preset number threshold, the network load of the primary carrier is greater than the third preset network load threshold, and the target number is greater than the second preset number threshold, where the second indication message is used to indicate that the target terminal enables the uplink transmission switching function in a preset time period. In this way, the number of times the server manages the uplink transmission switching function of the terminal can be reduced, and the efficiency of enabling the uplink transmission switching function by the terminal can be improved.
