The voice call service it carries is called Voice over New Radio (VoNR), which enables electronic devices to maintain a stable and high-speed data connection during a call.

[0003] However, due to development time constraints, the current VoNR network has not yet reached the stable state of Voice over Long-Term Evolution (VoLTE). Due to various network issues, such as network failures and IMS link abnormalities, VoNR voice calls cannot be connected normally, which means that VoNR calls fail to connect. Summary of the Invention

The processing module is used to actively release the first network and send a mobile registration update request of the first network to the network side device, or perform a cell switching process when the DRB used by the first network to transmit IMS data has not been established. The mobile registration update request is used to request re-registration to the first network, and the mobile registration update request includes target data, which is used to indicate that the electronic device has data to be sent.

When the DRB for transmitting IMS data of the first network receives the incoming call information, the electronic device can determine that the current network is abnormal, thereby switching from the first network to the second network to receive the incoming call information; or when the electronic device detects that the DRB for transmitting IMS data of the first network is not established, the electronic device can actively release the first network and send a mobile registration update request of the first network to the network-side device to re-register with the first network, and because the mobile registration update request includes target data indicating that the electronic device has data to be sent, it can induce the network-side device to re-establish the DRB for transmitting IMS data of the first network to receive the incoming call information; or when the electronic device detects that the DRB for transmitting IMS data of the first network is not established, the electronic device can determine that the source cell in the first network is abnormal, thereby performing a cell switching process to receive the incoming call information through the DRB for transmitting IMS data of the first network established in the switched cell.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0019] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0020] The paging method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0021] The paging method in the embodiment of the present application can be applied to a scenario where an electronic device receives an incoming call.

[0022] The wireless access portion of 5G is called New Radio (NR), and the voice service based on 5G is called VoNR. This means NR users can conduct voice services directly over the NR network without having to fall back to the Long Term Evolution (LTE) network, resulting in a higher-quality voice experience and a higher-speed data experience. Before the implementation of VoNR technology, making a voice call would cause the phone's network to fall back from 5G to 4G. However, VoNR technology supports concurrent 5G data and voice. Using VoNR not only shortens call connection establishment time and significantly improves connection success rates, but also reduces potential interruptions during calls. Furthermore, VoNR maintains a stable and high-speed 5G data connection during calls, ensuring an uninterrupted gaming and video experience. Currently, major manufacturers are accelerating plans to support VoNR functionality in electronic devices, and operators have essentially completed VoNR network coverage, gradually completing the commercialization of VoNR. Therefore, further improving VoNR's voice service capabilities is becoming increasingly important.

[0023] However, due to the time constraints of R&D, the current VoNR network has not actually reached a stable state like VoLTE. Due to various network problems, VoNR voice calls may fail or connection failures may occur, affecting the successful establishment of VoNR calls. The establishment of a VoNR call requires the network-side device to configure a Data Radio Bearer (DRB) for transmitting IMS data. However, due to various reasons, the network-side device may not configure DRBs for electronic devices. For example, the electronic device is out of sync with the network status, or the IMS link is abnormal, the network fails, etc., making the electronic device have no DRB available, which will result in the electronic device being unable to successfully receive incoming call information; and although the electronic device has DRBs available, the network may have an anomaly and fail to forward the request message in time, resulting in the electronic device being unable to receive incoming call information.

[0024] In the solution provided in the embodiment of the present application, the electronic device can detect whether the DRB for transmitting IMS data of the first network has been established. When the DRB for transmitting IMS data of the first network has been established, if the incoming call information is not received through the DRB for transmitting IMS data of the first network within the first preset time period, the electronic device switches from the first network to the second network; when the DRB for transmitting IMS data of the first network has not been established, the electronic device can actively release the first network and send a mobile registration update request of the first network to the network side device, and the mobile registration update request includes target data, and the target data is used to indicate that the electronic device has data to be sent; or perform a cell switching process; in this solution, since the electronic device can detect whether the DRB for transmitting IMS data of the first network has been established, when the electronic device detects that the DRB for transmitting IMS data of the first network has been established and has not been received through the DRB within the first preset time period, the electronic device switches from the first network to the second network. When the DRB used by the first network to transmit IMS data receives an incoming call, the electronic device can determine that the current network is abnormal, thereby switching from the first network to the second network to receive the incoming call; or when the electronic device detects that the DRB used by the first network to transmit IMS data is not established, the electronic device can actively release the first network and send a mobile registration update request of the first network to the network-side device to re-register with the first network, and because the mobile registration update request includes target data indicating that the electronic device has data to be sent, it can induce the network-side device to re-establish the DRB used by the first network to transmit IMS data to receive the incoming call; or when the electronic device detects that the DRB used by the first network to transmit IMS data is not established, the electronic device can determine that the source cell in the first network is abnormal, thereby performing a cell switching process to receive the incoming call through the DRB used by the first network to transmit IMS data established in the switched cell. That is, the electronic device can perform corresponding operations based on the establishment result of the detected DRB used by the first network to transmit IMS data, so that the VoNR voice can be connected normally.

[0025] The embodiment of the present application provides a paging method, Figure 1 FIG. 1 shows a flow chart of a paging method provided by an embodiment of the present application, which can be applied to electronic devices. Figure 1 As shown, the paging method provided in the embodiment of the present application may include the following steps 201 and 202A, or steps 201 and 202B.

[0026] Step 201: The electronic device detects whether a DRB for transmitting IMS data in a first network has been established.

[0027] Optionally, in an embodiment of the present application, the first network may be an NR network.

[0028] Optionally, in an embodiment of the present application, the DRB for transmitting IMS data may be established / configured by sending a Radio Resource Control (RRC) reconfiguration message via a network-side device.

[0029] Step 202A: When the DRB for transmitting IMS data on the first network has been established, if no incoming call information is received through the DRB for transmitting IMS data on the first network within a first preset time period, the electronic device switches from the first network to the second network.

[0030] Optionally, in an embodiment of the present application, the second network may be an LTE network.

[0031] It can be understood that when the DRB used to transmit IMS data in the first network has been established, but no incoming call information is received through the DRB used to transmit IMS data in the first network within the first preset time period, the electronic device can determine that the current network is abnormal, and thus switch from the first network to the second network to receive the incoming call.

[0032] Optionally, in the embodiment of the present application, since the time for an electronic device to wait for paging is generally about 20 seconds, the first preset time length can be set to 20 seconds. The specific value can be adjusted according to actual conditions and is not limited in the embodiment of the present application.

[0033] Optionally, in the embodiment of the present application, the first preset time duration may be a minimum threshold for the electronic device to reside in the first network and wait for receiving incoming call information.

[0034] Optionally, in an embodiment of the present application, in the above step 202A, "if the incoming call information is not received through the DRB used for transmitting IMS data of the first network within the first preset time period, switching from the first network to the second network" can be specifically carried out through the following steps A1 and A2.

[0035] Step A1: The electronic device starts a first timer and begins to detect whether an incoming call information is received through a DRB used for transmitting IMS data on a first network.

[0036] In an embodiment of the present application, when the electronic device detects that the DRB for transmitting IMS data on the first network has been established, it can start a first timer and detect whether incoming call information is received through the DRB for transmitting IMS data on the first network during the start of the first timer.

[0037] Step A2: When the first timer times out and it is detected that the DRB used to transmit IMS data through the first network does not receive the incoming call information, the electronic device switches from the first network to the second network.

[0038] In the embodiment of the present application, the first timer timeout is when the start time of the first timer exceeds the first preset time.

[0039] It is understandable that when the first timer times out and the electronic device does not receive the incoming call information, the electronic device can determine that the inability to receive the incoming call information is due to an abnormality in the current network. Therefore, the electronic device can actively switch to the second network to receive the call.

[0040] Optionally, in an embodiment of the present application, after the above-mentioned step A2, the paging method provided in the embodiment of the present application further includes the following steps B1 and B2, or steps B1 and B3.

[0041] Step B1: The electronic device starts a second timer and begins to detect whether an incoming call is received through the second network.

[0042] It is understandable that after switching to the second network, the electronic device may start the second timer, and during the period when the second timer is started, detect whether the electronic device receives incoming call information through the second network.

[0043] Step B2: When the second timer has not timed out and an incoming call is detected via the second network, the electronic device connects the incoming call via the second network and switches from the second network to the first network after the incoming call ends.

[0044] In the embodiment of the present application, the above-mentioned second timer not timing out means that the activation duration of the second timer does not exceed the second preset duration.

[0045] It is understandable that if the electronic device receives an incoming call message during the start-up period of the second timer, it is considered that falling back to the second network to receive the incoming call message is valid, and the electronic device can actively return to the first network after the call ends.

[0046] In this way, when the electronic device has high requirements for data transmission rate and network quality and needs to reside in a high-standard network (ie, the first network) to provide users with smoother services, it can avoid affecting the normal operation of the electronic device.

[0047] Optionally, in the embodiment of the present application, the second preset time length may be a maximum threshold for the electronic device to wait for receiving incoming call information while residing in the second network.

[0048] Optionally, in an embodiment of the present application, since the time it takes for the electronic device to automatically hang up after not receiving a ringing message is generally about 60 seconds, the total duration of the above-mentioned first preset duration and the second preset duration can be set to 60 seconds. The specific value can be adjusted according to actual conditions, and the embodiment of the present application does not limit it.

[0049] Optionally, in the embodiment of the present application, the electronic device may turn off the second timer after receiving the incoming call information, and actively return to the first network after the call ends.

[0050] Optionally, in the embodiment of the present application, the incoming call information received by the electronic device may be a paging message (Paging) or an INVITE message in the IMS domain.

[0051] Step B3: When the second timer times out and it is detected that no incoming call information is received through the second network, the electronic device switches from the second network to the first network and re-registers in a cell different from the source cell in the first network.

[0052] In the embodiment of the present application, the second timer timeout is when the start time of the second timer exceeds the second preset time.

[0053] It can be understood that after switching to the second network, the electronic device can start the second timer and detect whether the electronic device receives the incoming call information through the second network during the start of the second timer. If the electronic device does not receive the incoming call information through the second network during the start of the second timer, it is considered that falling back to the second network to receive the incoming call information is invalid. The electronic device actively returns to the first network after the second timer expires. Since the electronic device resides in the first network, the electronic device determines that the inability to receive the incoming call information is caused by the current network anomaly. Therefore, in order to avoid the problem of failure to receive the incoming call information due to network anomaly again, the electronic device can re-register to a cell different from the source cell in the first network after returning to the first network.

[0054] Optionally, in an embodiment of the present application, the electronic device may re-register to a cell different from the source cell in the first network according to a comprehensive ranking of the cells.

[0055] Optionally, in an embodiment of the present application, when the first timer has not timed out and it is detected that the DRB used to transmit IMS data through the first network receives incoming call information, the electronic device connects the incoming call through the first network.

[0056] In the embodiment of the present application, the above-mentioned first timer not timing out means that the activation duration of the first timer does not exceed the first preset duration.

[0057] Optionally, in an embodiment of the present application, when the first timer has not timed out and the electronic device receives incoming call information through the DRB used to transmit IMS data on the first network, the electronic device can turn off the first timer and connect the incoming call through the first network.

[0058] Step 202B: When the DRB used by the first network for transmitting IMS data is not established, the electronic device actively releases the first network and sends a mobile registration update request of the first network to the network side device, or performs a cell switching process.

[0059] In an embodiment of the present application, the mobile registration update request is used to request re-registration to the first network. The mobile registration update request includes target data, which is used to indicate that the electronic device has data to be sent.

[0060] Optionally, in an embodiment of the present application, the above-mentioned target data can be data for the electronic device to induce the network side device to re-establish the DRB of the first network for transmitting IMS data, that is, the electronic device does not have data to be sent, or it can be data that the electronic device needs to send, for example: data to be sent after the electronic device receives a paging message forwarded by the first network.

[0061] Optionally, in an embodiment of the present application, the electronic device may actively perform a local release to disconnect the radio resource control RRC connection of the first network and enter an idle state.

[0062] It is understandable that the electronic device can carry target data in the mobile registration update request to inform the network side device that the electronic device needs to send IMS data, so that the network side device re-establishes the DRB of the first network for transmitting IMS data.

[0063] It can be understood that when the DRB used by the first network to transmit IMS data is not established, the electronic device cannot receive paging (Paging) in the idle state and cannot receive paging request (INVITE) in the connected state.

[0064] Optionally, in an embodiment of the present application, after "the electronic device actively releases the first network and sends a mobile registration update request of the first network to the network side device" in the above step 202B, the paging method provided in the embodiment of the present application further includes the following step C1.

[0065] Step C1: The electronic device receives a mobile registration update response sent by the network-side device.

[0066] In an embodiment of the present application, the above-mentioned mobile registration update response is used to instruct the network side device to re-establish the DRB of the first network for transmitting IMS data, and the DRB of the first network for transmitting IMS data is used by the electronic device to receive incoming call information.

[0067] It can be understood that after the network side device receives the mobile registration update request sent by the electronic device, since the mobile registration update request carries the target data, the network side device can determine that the electronic device needs to send data, so that the network side device can re-establish the first network for transmitting the DRB of IMS data, and send a mobile registration update response to the electronic device to instruct the network side device to re-establish the DRB of the first network for transmitting IMS data, so that the electronic device can receive incoming call information through the re-established DRB of the first network for transmitting IMS data.

[0068] Optionally, in an embodiment of the present application, the “electronic device performs a cell switching process” in the above step 202B can be specifically implemented through the following steps D1 to D3.

[0069] Step D1: The electronic device measures the signal quality of at least one neighboring cell of a source cell in a first network.

[0070] In an embodiment of the present application, when the DRB used by the first network to transmit IMS data is not established, the electronic device can determine that the source cell in the first network is abnormal, and then perform cell switching by measuring the signal quality of at least one neighboring cell of the source cell in the first network, so as to receive incoming call information through the DRB used by the first network to transmit IMS data established in the new cell.

[0071] Optionally, in the embodiment of the present application, the at least one neighboring cell may include a same-frequency neighboring cell and a different-frequency neighboring cell.

[0072] Step D2: When there is a cell with a signal quality greater than or equal to a preset threshold in at least one neighboring cell, the electronic device switches from the source cell in the first network to the target cell.

[0073] In the embodiment of the present application, the target cell is a cell with the highest signal quality among at least one neighboring cell.

[0074] Optionally, in an embodiment of the present application, when there is a cell with a signal quality greater than or equal to a preset threshold in at least one neighboring cell, the electronic device can take the cell with the highest signal quality among the neighboring cells with signal quality greater than or equal to the preset threshold as the target cell and switch to the target cell.

[0075] For example, if there is a cell with a signal quality greater than or equal to -115dBm in at least one neighboring cell, the electronic device may select the cell with the highest signal quality among the cells with a signal quality greater than or equal to -115dBm as the target cell and switch to the target cell.

[0076] Optionally, in an embodiment of the present application, the target cell may be a same-frequency neighboring cell or a different-frequency neighboring cell.

[0077] Optionally, in an embodiment of the present application, when there is no cell with a signal quality greater than or equal to a preset threshold in at least one neighboring cell, the electronic device does not perform an operation.

[0078] Optionally, in the embodiment of the present application, “switching the electronic device from the source cell in the first network to the target cell” in the above step D2 can be specifically implemented through the following steps F1 and F2.

[0079] Step F1: When the target cell is a same-frequency neighboring cell, the electronic device reports a first measurement event to a network-side device.

[0080] In the embodiment of the present application, the first measurement event is used to indicate that the signal quality of the co-frequency neighboring cell is greater than the signal quality of the serving cell.

[0081] Optionally, in the embodiment of the present application, the first measurement event may be an A3 event.

[0082] Optionally, in an embodiment of the present application, when the signal quality of the co-frequency neighboring cell is the highest and the signal quality of the co-frequency neighboring cell is less than the signal quality of the serving cell, that is, when the requirements for switching cells are not met, the electronic device can ignore the A3 event configured by the network side device and actively report a first measurement event, that is, the electronic device can actively report a first measurement event that meets the requirements for switching to the co-frequency neighboring cell in order to switch to the co-frequency neighboring cell.

[0083] For example, if the signal strength of a co-frequency neighboring cell is -100dBm and the A3 event threshold configured by the network device is -97dBm, the requirement for cell handover is not met: the neighboring cell signal quality is greater than the serving cell signal quality. Therefore, the electronic device can ignore the A3 event configured by the network device and configure an A3 event on its own (for example, an A3 event with an event threshold of -103dBm) and report it. It can be understood that at this time, the neighboring cell signal quality is greater than the serving cell signal quality, which can trigger a co-frequency neighboring cell handover.

[0084] Step F2: The electronic device receives a handover instruction message sent by the network-side device, and switches from the source cell in the first network to the same-frequency neighboring cell according to the handover instruction message.

[0085] It can be understood that after the network side device receives the first measurement event reported by the electronic device to indicate that the signal quality of the same-frequency neighboring cell is greater than the signal quality of the serving cell, it can send a switching indication information to the electronic device to instruct the electronic device to switch from the source cell in the first network to the same-frequency neighboring cell.

[0086] Optionally, in the embodiment of the present application, “switching the electronic device from the source cell in the first network to the target cell” in the above step D2 can be specifically implemented through the following steps F3 and F4.

[0087] Step F3: When the target cell is an inter-frequency neighboring cell, the electronic device reports a second measurement event to the network-side device.

[0088] In the embodiment of the present application, the second measurement event is used to indicate that the signal quality of the serving cell is less than a preset threshold.

[0089] Optionally, in the embodiment of the present application, the second measurement event may be an A2 event.

[0090] Optionally, in an embodiment of the present application, when the signal quality of the heterofrequency neighboring cell is the highest and the signal quality of the serving cell is greater than a preset threshold value, that is, when the conditions for the network side device to send a B2 event are not met, the electronic device can ignore the A2 event configured by the network side device and actively report a second measurement event, that is, the electronic device can actively report a second measurement event indicating that the signal quality of the serving cell is less than the preset threshold value, so as to induce the network side device to send a B2 event, and then switch to the heterofrequency neighboring cell.

[0091] For example, if the preset threshold is -110dBm and the A2 event threshold configured by the network device is -97dBm, the signal quality of the serving cell is not less than the preset threshold. Therefore, the electronic device can ignore the A2 event configured by the network device and configure an A2 event of its own (for example, an A2 event with a threshold of -112dBm) and report it. It is understood that the signal quality of the serving cell being less than the preset threshold can trigger the network device to issue a B2 event.

[0092] Step F4: The electronic device receives a third measurement event sent by the network-side device, and switches from the source cell in the first network to an inter-frequency neighbor cell according to the third measurement event.

[0093] In the embodiment of the present application, the third measurement event is used to indicate that the signal quality of the serving cell is less than a preset threshold value, and the signal quality of the inter-frequency neighboring cell is greater than the preset threshold value.

[0094] Optionally, in the embodiment of the present application, the third measurement event may be a B2 event.

[0095] It can be understood that after the network side device receives the second measurement event reported by the electronic device indicating that the signal quality of the service cell is less than the preset threshold value, it can send a third measurement event to the electronic device so that the electronic device can switch from the source cell in the first network to the heterofrequency neighboring cell according to the third measurement event.

[0096] Step D3: The electronic device receives the incoming call information via the DRB of the first network for transmitting IMS data.

[0097] In the embodiment of the present application, the DRB used by the first network to transmit IMS data is established by the network side device in the target cell.

[0098] It can be understood that after the electronic device switches from the source cell in the first network to the target cell, the network side device can establish a DRB of the first network for transmitting IMS data in the target cell, so that the electronic device can receive incoming call information through the DRB of the first network for transmitting IMS data.

[0099] In this way, abnormal cells can be prevented from affecting the electronic device's reception of incoming call information.

[0100] An embodiment of the present application provides a paging method. Since the electronic device can detect whether the DRB for transmitting IMS data of the first network has been established, when the electronic device detects that the DRB for transmitting IMS data of the first network has been established and no incoming call information is received through the DRB for transmitting IMS data of the first network within a first preset time period, the electronic device can determine that the current network is abnormal, thereby switching from the first network to the second network to receive the incoming call information; or when the electronic device detects that the DRB for transmitting IMS data of the first network has not been established, the electronic device can actively release the first network and send a mobile registration update request of the first network to the network side device to re-register with the first network, and since the mobile registration update request includes target data indicating that the electronic device has data to be sent, the network side device can be induced to re-establish the DRB for transmitting IMS data of the first network to receive the incoming call information; or when the electronic device detects that the DRB for transmitting IMS data of the first network has not been established, the electronic device can determine that the source cell in the first network is abnormal, thereby performing a cell switching process to receive the incoming call information through the DRB for transmitting IMS data of the first network established in the switched cell. That is to say, the electronic device can perform corresponding operations based on the detected establishment result of the DRB used by the first network to transmit IMS data, so that the VoNR voice can be connected normally.
