     Referring to  FIG. 2 , a schematic flow diagram of a method for displaying a service identifier according to the embodiments of the present disclosure is illustrated, which method may be applied to the electronic device shown in  FIG. 1 a    or  FIG. 1 b   . The electronic device supports an eMBB service and a doubly connected mode. In the doubly connected mode, the electronic device establishes a first communication connection with a first network device and establishes a second communication connection with a second network device. The first and second network devices are on a first 5G NSA network. The first network device is an evolutional 4G nodeB (eNB), and the second network device is a 5G nodeB (gNB). A core of the first 5G NSA network is a packet 5G NG core. The first network device communicates with the second network device and the NG core. As shown in the figure, the method for displaying a service identifier may include operations as follows. 
     In operation S 201 , the electronic device acquires a NR Reference Signal Receiving Power (RSRP) and an upstream transmission bandwidth threshold, when the electronic device activates the eMBB service. In an implementation, the electronic device may acquire the NR RSPR and the uplink transmission bandwidth threshold by detecting on the local side, or may acquire such information from the NG core through the nodeB. 
     In operation S 202 , the electronic device determines a service identifier of the eMBB service according to the NR RSPR and the uplink transmission bandwidth threshold. 
     The service identifier indicates a transmission form of the service data of the eMBB service under different network architectures. For example, in a 4G LTE network, the electronic device displays a 4G identifier, such as 4G or LTE eMBB, on an interface for the eMBB service. For another example, in a 5G network, the electronic device displays a 5G identifier, such as 5G or 5G eMBB, on the interface for the eMBB service. The identifier is used to indicate the data distribution situation under the uplink data distribution scheme performed on the electronic device. For example, if a 4G identifier is displayed, it means that an uplink data distribution scheme is adopted in which a part of the data is transmitted to the NG core through the eNB and the other part of the data is transmitted to the NG core through the gNB, and an LTE_ratio (4G ratio) is greater than a NR_ratio (5G ratio). For another example, if 5G eMBB is displayed, it means that no uplink data distribution scheme is adopted, or an uplink data distribution scheme is adopted in which the LTE_ratio is smaller than the NR_ratio. The power threshold and the uplink threshold may be set in advance, which do not limit the embodiments of the disclosure. 
     The LTE_ratio may be calculated as follows: LTE_ratio=(10 GB-A)/10 GB, where A is an uplink transmission bandwidth pre-assigned to the LTE network. The NR_ratio may be obtained by subtracting the LTE_ratio from the uplink transmission bandwidth threshold, i.e., NR_ratio=the uplink transmission bandwidth threshold-LTE_ratio. 
     In operation S 203 , the electronic device displays the service identifier of the eMBB service. 
     In the embodiments of the present disclosure, when it is detected that the electronic device activates an eMBB service, the electronic device acquires a NR RSRP and an uplink transmission bandwidth threshold, determines a service identifier of the eMBB service according to the NR RSPR and the upstream transmission bandwidth threshold, and displays the service identifier on an interface. As can be seen, during the execution of the eMBB service, the electronic device can determine the corresponding service identifier according to the status of the uplink data, and display for example a 4G identifier or a 5G identifier. In this way, the actual data transmission status of the electronic device during the eMBB service can be accurately, intuitively and comprehensively displayed, which is beneficial to improve the comprehensiveness and accuracy of the information display of the electronic device under the eMBB service. 
     In a possible example, after the electronic device activates the eMBB service, the method may further include: sending, by the electronic device, to the first network device a service identifier query request for querying the service identifier of the eMBB service; and receiving service identifier indication information from the first network device. 
     In an implementation, the service identifier indication information includes the NR RSRP and the uplink transmission bandwidth threshold; and after receiving the service identifier indication information, the electronic device may determine the service identifier of the eMBB service according to the NR RSRP and the uplink transmission bandwidth threshold included in the service identifier indication information. 
     In this case, for example, after the electronic device activates the eMBB service, the electronic device sends the service identifier query request to the NG core through a control channel with the first network device, i.e., the eNB. That is, the electronic device sends to the first network device a service identifier query request for querying the service identifier of the eMBB service, and the first network device forwards the service identifier query request to the NG core. In response to the service identifier query request, the NG core generates service identifier indication information and sends it to the first network device, the service identifier indication information including the NR RSRP and the uplink transmission bandwidth threshold. The first network device returns the service identifier indication information to the electronic device, so that the electronic device may determine the service identifier of the eMBB service according to the service identifier indication information, in particular the NR RSRP and the uplink transmission bandwidth threshold. 
     The eMBB service is one of the important functions of the electronic device. After the electronic device accesses the first 5G NSA network, the type of the service identifier corresponding to the data service supported by the current network architecture may be determined by means of the service identifier query request, that is, an agreement on a service identifier query mechanism may be made at the protocol level. In addition, the service identifier information of the eMBB service under the network architecture may exist on the network side. 
     Alternatively, in an implementation, the electronic device may send the service identifier query request through a control channel (such as a Common Control Channel (CCCH) or a Dedicated Control Channel (DCCH)) with the nodeB. That is, the nodeB for example forwards the service identifier query request to the NG core. After receiving the service identifier query request from the electronic device, the NG core may generate service identifier indication information according to a service identifier of the eMBB service that is pre-configured locally, and send the generated service identifier indication information to the electronic device through the nodeB, the service identifier indication information indicating the service identifier of the eMBB service to be displayed. The electronic device may extract the service identifier of the eMBB service to be displayed from the service identifier indication information. Optionally, the electronic device may store the determined service identifier of the eMBB service. 
     The service identifier of the eMBB service may include a 4G identifier and a 5G identifier. The specific representations of the 4G and 5G identifiers may vary among different operators, which are not limited in this disclosure. 
     In this example, the electronic device can quickly and accurately determine the service identifier of the eMBB service by means of the query mechanism, improving the accuracy and efficiency of displaying the service identifier. 
     The electronic device may be preset in such a manner that it is enabled to access multiple different network architectures, such as a 4G LTE network, a 5G NSA network (including various sub-network architectures), and a 5G Standalone (SA) network. Resources (such as channels) configured for the electronic device to support the eMBB service may be different under different network architectures. At the level of operators, different operators may deploy mobile networks with different network architectures, and the assigned frequency domain resources are different. Based on this, the service identifier that needs to be displayed may be determined by detecting the difference between the channels currently enabled by the eMBB service. 
     In this example, since different service channels are enabled when different network architectures support the eMBB service, the electronic device may detect the currently enabled channels, and perform comparison and query based on the different characteristic parameters (such as the RSRP and the uplink transmission bandwidth threshold) of the channels, to obtain the service identifier to be displayed, thereby improving the accuracy and instantaneity of the electronic device in displaying the service identifier. 
     In a possible example, the displaying, by the electronic device, the service identifier on an interface for the eMBB service of the electronic device may include: displaying the service identifier at a preset position of an interface for the eMBB service of the electronic device, the preset position matching a display position of the electronic device where a network connection status is displayed. 
     The preset position matching a display position of the electronic device where a network connection status is displayed, may mean that the preset position may be adjacent to, opposite to, or separated by a preset distance (for example, 1 mm to 150 mm) from the display position where the network connection status is displayed, which is not uniquely defined here. In addition, the display parameters (such as color, background color, font, and size) of the service identifier may be consistent with those of the network connection state, or may also be inconsistent therewith, which is also not uniquely defined here. For example, the font size and the background color of the service identifier may be set to be the same as those of the network connection status. 
     In this example, the electronic device can display the service identifier at a preset position on an interface for the eMBB service, with the preset position matching the display position where the network connection status is displayed. As such, the current communication status of the electronic device can be completely presented, and the comprehensiveness of the electronic device in displaying the communication status information can be improved. 
     In a possible example, the displaying, by the electronic device, the service identifier on an interface for the eMBB service of the electronic device may include: switching, by the electronic device, from a network connection status identifier to the service identifier on the interface for the eMBB service of the electronic device. 
     In a possible example, the displaying, by the electronic device, the service identifier on an interface for the eMBB service of the electronic device may include: determining, by the electronic device, an interface for the eMBB service; querying a corresponding relationship between a pre-configured interface and a display position for the service identifier, to determine a corresponding target display position on the interface for the eMBB service; and displaying the service identifier at the target display position. 
     In an implementation, the preset position may be different positions on the electronic device for different types of interfaces. For example, for a data status interface, the service identifier may be displayed in the upper left corner of the interface; and for an integrated application interface that is presented in response to opening of an another application in the data status interface, the service identifier may be displayed for example in the upper-middle part of the integrated application interface. 
     In this example, for different types of interfaces for the eMBB service, the electronic device can flexibly adapt the display position of the service identifier on the current service interface, thereby improving the flexibility and intelligence of the electronic device in displaying the service identifier. 
     In a possible example, the method may further include: transmitting, by the electronic device, service data of the eMBB service through the first 5G NSA network. 
     The service data of the eMBB service may include the user&#39;s uplink data. 
     In this example, the electronic device can transmit the uplink data of the eMBB service through the first 5G NSA network, which is consistent with the network architecture associated with the currently displayed service identifier, thereby improving the consistency of the service identifier displayed by the electronic device. 
     The transmitting, by the electronic device, the uplink data of the eMBB service through the first 5G NSA network may include: transmitting the uplink data of the service through the second communication connection and the NG core (for the case where no uplink data distribution scheme is adopted); or transmitting the uplink data of the eMBB service through the second and first communication connections and the NG core (for the case where an uplink data distribution scheme is adopted). 
     In an implementation, the uplink data may be transmitted to the NG core directly through the second communication connection for interaction, or may be transmitted to the NG core directly through the first communication connection for interaction, according to the actual situation. 
     In this example, since the electronic device is in the doubly connected mode, the transmission of the service data can be flexibly selected based on the quality of the channels, thereby improving the efficiency and stability of the data transmission. 
     Referring to  FIG. 3 , a schematic flowchart of a method for displaying a service identifier according to the embodiments of the present disclosure is illustrated, which is consistent to the embodiment shown in  FIG. 2 . The method may be applied to the electronic device in the communication system shown in  FIG. 1 a   . The electronic device supports an eMBB service and a doubly connected mode.

The first network device communicates with the second network device and the NG core. As shown in the figure, the method for displaying a service identifier may include operations as follows. 
     In operation S 301 , the electronic device sends, to the first network device, a service identifier query request for querying a service identifier of the eMBB service, when it is detected that the electronic device activates the eMBB service. 
     In operation S 302 , the electronic device receives service identifier indication information from the first network device, the service identifier indication information including a NR RSRP and an uplink transmission bandwidth threshold. 
     In operation S 303 , the electronic device determines the service identifier of the eMBB service according to the NR RSRP and the uplink transmission bandwidth threshold included in the service identifier indication information. 
     In operation S 304 , the electronic device displays the service identifier on an interface for the eMBB service of the electronic device. 
     In the embodiments of the present disclosure, when it is detected that the electronic device activates an eMBB service, the electronic device acquires a service identifier matching the current communication status of the electronic device is acquired, and displays the service identifier on the interface for the eMBB service of the electronic device. As can be seen, during the execution of the eMBB service, the electronic device can display a proper service identifier, such as a first service identifier or a second service identifier, according to the communication status. In this way, the actual communication status of the electronic device during the eMBB service can be accurately, intuitively and comprehensively displayed, which is beneficial to improve the comprehensiveness and accuracy of the information display of the electronic device under the eMBB service. 
     In addition, the electronic device can quickly and accurately determine the service identifier of the eMBB service by means of the query mechanism, improving the accuracy and efficiency of displaying the service identifier.
