User plane data of the electronic device may be transmitted to the core network device NGC 104  through the base station  102  and the base station  103  respectively. The base station  103  may be communicatively connected to the core network device  104 . The core network device NGC 104  may support a dual connection mode.

In this way, a risk of a core network signaling being overloaded may be solved, and the electronic device may achieve voice call services, such as an eMBB service, through the network. 
     As shown in  FIG. 2A ,  FIG. 2A  is a flowchart of a control method for displaying a service identifier in an electronic device according to an embodiment of the present disclosure. The method may be applied in the electronic device shown in  FIG. 1 . The electronic device may support the eMBB service and the dual connection mode. In the dual connection mode, the electronic device may establish a first communication connection with a first network device and establish a second communication connection with a second network device. Each of the first network device and the second network device may be a network device in a 5G NSA network. The first network device may be a fourth-generation (4G) base station eNB. The second network device may be a 5G base station gNB. A core network of the 5G NSA network may be the NGC. The first network device may be communicatively connected to the second network device, and the first network device may be communicatively connected to the NGC. As shown in  FIG. 2A , the control method for displaying the service identifier may include following operations. 
     In an operation  201 , the electronic device may send a query request for resource allocation information to the first network device, in response to the electronic device being detected to be in a downlink data service scenario. 
     In the present embodiment, the electronic device may detect the service scenario of the electronic device. The electronic device may send the query request for resource allocation information in response to the electronic device being detected to be in the downlink data service scenario. Considering that the control plane signaling may be transmitted through the eLTE base station, the query request for resource allocation information may be sent to the first network device. The downlink data service may refer to the electronic device receiving data sent by the eNB or the gNB. 
     In an operation  202 , the resource allocation information sent by the first network device may be received. 
     The resource allocation information may include at least one of: a network resource block, a file size, an available downlink bandwidth, etc. In the present embodiment, after receiving the query request for resource allocation information, the first network device may send first resource allocation sub-information corresponding to the first network device to the electronic device. The first resource allocation sub-information may include the file size and the available downlink bandwidth corresponding to the first network device. The first network device may also forward the query request for resource allocation information to the second network device, and receive second resource allocation sub-information sent by the second network device. The second resource allocation sub-information may include a first network resource block of the second network device, a file size of the second network device, and an available downlink bandwidth of the second network device. Subsequently, the first network device may send the second resource allocation sub-information to the electronic device. The first resource allocation sub-information may carry a first device identifier of the first network device, and the second resource allocation sub-information may carry a second device identifier of the second network device. In this way, the electronic device may distinguish the first resource allocation sub-information and the second resource allocation sub-information based on the first device identifier and the second device identifier. 
     In an operation  203 , a target service identifier of the electronic device may be determined based on the resource allocation information, and the target service identifier may be displayed. 
     The service identifier may be configured to indicate a form of the service data being transmitted under each of various network architectures. For example, in the 4G LTE network, the electronic device may display an icon “VoLTE” on a calling interface in the downlink data service. The identifier “VoLTE” may be configured to indicate that the electronic device may support the downlink data service through the 4G LTE network. In detail, the service data of the downlink data service may be transmitted through the 4G LTE network. 
     The service identifier may be at least one of: NR, uRLLC, 4G, 5G, etc., which will not be limited herein. 
     Alternatively, the resource allocation information may include the first network resource block of the second network device. In the operation  203 , determining and displaying the target service identifier of the electronic device based on the resource allocation information, may include following operations. 
     In an operation  31 , in response to the first network resource block being less than a first threshold, a channel quality indicator of the second network device may be determined. 
     In an operation  32 , in response to the channel quality indicator being less than a second threshold, the target service identifier may be determined as a first service identifier, and the first service identifier may be displayed on a display interface of the electronic device. In response to the channel quality indicator being greater than the second threshold, the target service identifier may be determined as a second service identifier, and the second service identifier may be displayed on the display interface of the electronic device. The first service identifier and the second service identifier may indicate transmission form of service data in different network architectures. 
     The electronic device may preset the first threshold for the network resource block and the second threshold for the channel quality indicator. A threshold may refer to a size of the network resource block, for example, the first threshold may refer to a size of a maximal network resource block. For example, the first threshold may be 100, and the second threshold may be 10. After the first network resource block is determined, it may be determined whether the first network resource block is less than the first threshold. In response to the first network resource block being less than the first threshold, the channel quality indicator of the second network device may further be determined. 
     Alternatively, the above-mentioned first network resource block is sent from the second network device to the first network device, in response to the query request is forwarded from the first network device to the second network device. 
     Alternatively, determining the channel quality indicator of the second network device may include following operations. 
     In an operation A1, a channel parameter and signal strength of the second network device may be acquired. 
     In an operation A2, the channel quality indicator of the second network device may be determined based on the channel parameter and the signal strength. 
     The channel parameter may include at least one of: a transmission rate, a signal-to-noise ratio, channel gain, and a noise power. In the present embodiment, the channel quality indicator may be determined based on the channel parameter and the signal strength. In response to the channel quality indicator being less than the second threshold, the target service identifier may be determined as the first service identifier, the first service identifier may be displayed on the display interface of the electronic device. In response to the channel quality indicator being greater than the second threshold, the target service identifier may be determined as the second service identifier, and the second service identifier may be displayed on the display interface of the electronic device. The first service identifier and the second service identifier may indicate transmission form of service data in different network architectures. 
     Alternatively, the first service identifier may be a 4G icon indicating transmission form of service data in 4G network, and the second service identifier may be a 5G icon indicating transmission form of service data in 5G network. 
     As shown in  FIGS. 2B to 2C ,  FIG. 2B  is a presentative view of displaying the first service identifier on the display interface according to an embodiment of the present disclosure. As shown in  FIG. 2B , the first service identifier may be the “4G” icon.  FIG. 2C  is a presentative view of displaying the second service identifier on the display interface according to an embodiment of the present disclosure. As shown in  FIG. 2C , the second service identifier may be the “5G” icon. 
     Alternatively, the resource allocation information may include a first available downlink bandwidth of the first network device and a second available downlink bandwidth of the second network device, and determining the target service identifier of the electronic device based on the resource allocation information may include following operations. 
     The target service identifier of the electronic device may be determined based on the first available downlink bandwidth and the second available downlink bandwidth. 
     The electronic device may compare the first available downlink bandwidth with the second available downlink bandwidth after obtaining the first available downlink bandwidth and the second available downlink bandwidth. In response to the first available downlink bandwidth being greater than the second available downlink bandwidth, the target service identifier may be determined as the first service identifier, and the first service identifier may be displayed on the display interface of the electronic device. In response to the first available downlink bandwidth being less than the second available downlink bandwidth, the target service identifier may be determined as the second service identifier, and the second service identifier may be displayed on the display interface of the electronic device. The first service identifier and the second service identifier may indicate transmission form of service data in different network architectures. 
     In order to display the service identifier on the display interface of the electronic device, a service interface of the downlink data service may be determined firstly, correspondence between a pre-configured service interface and a display position of the service identifier may be enquired, and a target display position corresponding to the service interface of the downlink data service may be determined. Subsequently, the service identifier may be displayed at the target display position. In a specific implementation, a preset display position of the service identifier may be variable for various types of service interfaces. For example, on an interface of a calling state, the service identifier may be displayed at an upper left corner of the interface. In another example, in an application interface of another application, the service identifier may be displayed at an upper middle portion of the interface. In this way, the electronic device may flexibly adjust and adapt the display position of the service identifier on a current service interface for each of various types of service interfaces of the downlink data service, such that the electronic device may have higher flexibility and intelligence for displaying the service identifier. 
     Alternatively, in the present embodiment, before the electronic device sends the query request for resource allocation information to the first network device, the method further includes: in response to the electronic device detecting a switch-on event, performing a switch-on registration process, receiving network description information of the 5G NSA network sent from the first network device, and determining a set of service identifiers of the electronic device based on the network description information, and the set of service identifiers may include the target service identifier. The network description information may include at least a type and a capability of the NGC network. 
     A service identifier set may include following identifiers: 4G VoLTE, VoLTE, and VoNR. The 4G VoLTE may be configured to indicate that the downlink data service is supported by an EPC in the 5G NSA system. The VoLTE may be configured to indicate that the downlink data service is supported by the NGC and 4G access network in the 5G NSA system cooperatively (specifically, the data may be transmitted from the 4G access network to the core network NPC, or from a 5G access network to the 4G access network and further to the core network NPC). The VoNR may be configured to indicate that the downlink data service is supported by the NGC in the 5G NSA system. 
     In a specific implementation, while the electronic device is performing the switch-on registration process, the network side may determine a type of the base station that the electronic device accesses, and a cell at which the electronic device currently resides, i.e. the network side may determine that the network accessed by the electronic device is the 5G NSA network. Subsequently, the network side may send a type and a capability of a core network device of the network to the electronic device. The type may include EPC and/or NGC, and the capability may include whether an IMS voice service is supported. In addition, the service identifier set may include correspondence between the network description information and the service identifier of the downlink data service. In this way, the electronic device may complete configuration of the service identifier of the downlink data service quickly during the switch-on registration process. In this way, in a subsequent process of enabling the downlink data service, in response to an accessed service operator remaining unchanged, the service identifier may be displayed based on the pre-configured service identifier directly, so as to improve an efficiency and accuracy of the electronic device displaying the service identifier. 
     It may be seen that, in the present embodiment, in response to the electronic device being detected to be in the downlink data service scenario, the electronic device may send the query request for resource allocation information to the first network device, receive the resource allocation information sent by the first network device, determine and display the target service identifier of the electronic device based on the resource allocation information. In this way, as the electronic device is maintained in the dual connection mode, the form for transmitting the service data may be selected flexibly based on the resource allocation information of the network device, such that the efficiency and stability of data transmission may be improved, and the actual communication status of the electronic device may be displayed accurately, intuitively and comprehensively, improving comprehensiveness and accuracy of the electronic device displaying information. 
     In conformity with the embodiment shown in  FIG. 2A , as shown in  FIG. 3 ,  FIG. 3  is a flowchart of a control method for displaying a service identifier in an electronic device according to an embodiment of the present disclosure. The method may be applied in the electronic device shown in  FIG. 1 . The electronic device may support the eMBB service and the dual connection mode. In the dual connection mode, the electronic device may establish a first communication connection with a first network device and establish a second communication connection with a second network device. Each of the first network device and the second network device may be a network device in a 5G NSA network. The first network device may be a fourth-generation (4G) base station eNB. The second network device may be a 5G base station gNB. A core network of the 5G NSA network may be the NGC. The first network device may be communicatively connected to the second network device, and the first network device may be communicatively connected to the NGC. As shown in  FIG. 3 , the present control method for displaying the service identifier may include following operations. 
     In an operation  301 , in response to the electronic device being detected to be in the downlink data service scenario, the electronic device may send the query request for resource allocation information to the first network device. 
     In an operation  302 , the resource allocation information sent by the first network device may be received. 
     In an operation  303 , the resource allocation information may include the first network resource block of the second network device. In response to the first network resource block being less than the first threshold, the channel quality indicator of the second network device may be determined. 
     In an operation  304 , in response to the channel quality indicator being less than the second threshold, the target service identifier may be determined as the first service identifier, and the first service identifier may be displayed on the display interface of the electronic device. In response to the channel quality indicator being greater than the second threshold, the target service identifier may be determined as the second service identifier, and the second service identifier may be displayed on the display interface of the electronic device. The first service identifier and the second service identifier may indicate transmission form of service data in different network architectures. 
     It may be seen that, in the present embodiment, in response to the electronic device being detected to be in the downlink data service scenario, the electronic device may send the query request for resource allocation information to the first network device, and receive the resource allocation information sent by the first network device. The resource allocation information may include the first network resource block of the second network device. In response to the first network resource block being less than the first threshold, the electronic device may determine the channel quality indicator of the second network device. In response to the channel quality indicator being less than the second threshold, the target service identifier may be determined as the first service identifier, and the first service identifier may be displayed on the display interface of the electronic device.
