[0033] In this way, during the network switching process, the data session carried by the original network may be disconnected, so the continuity of the data session cannot be ensured, resulting in poor communication effect.

[0040] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0041] The following embodiments of the present disclosure can be applied to Figure 1A The communication system 100, or a portion thereof, is shown but is not limited thereto.

The entities may be connected or disconnected, and the connection may be in any manner, which may be direct or indirect, and may be wired or wireless.

[0042] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, next-generation systems based on them, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0043] In the related technology, the function of supporting the interoperability between VoNR and / or VoLTE, and VoWiFi is supported. For example, you can access a cellular network or a WiFi network to use services. If the original network is no longer available, or the new network can provide better services, you can initiate a switching request to the new network to request access to the new network and use the services provided by the new network. In this way, during the network switching process, the data session carried by the original network may be disconnected. Therefore, the continuity of the data session cannot be ensured, resulting in poor communication effects.

[0044] In order to solve the above technical problems, the embodiments of the present disclosure provide a communication control method, by sending a first message, wherein the first message at least includes: a request type, the request type is used to request to switch from a first connection to a second connection, the first connection includes: a data session, and receiving a second message, wherein the second information is used to indicate whether to support maintaining the data session, and determine whether to switch from the first connection to the second connection based on the second information. Thus, when requesting to switch networks, the first connection before the switch is indicated to the new network that includes the data session, and based on the second information indicated by the new network, it is learned whether the new network supports maintaining the data session. When determining whether to switch from the first connection to the second connection based on the second information, the continuity of the data session can be ensured and the communication effect can be improved.

[0045] In the embodiment of the present disclosure, the above-mentioned service may be, for example, a voice service, or may also be a video service. Therefore, the communication control method provided in the embodiment of the present disclosure can be effectively applied to personalized service scenarios, thereby improving practicality.

[0046] In the embodiment of the present disclosure, the first connection mentioned above may be a communication connection between the terminal and the original network. The second connection mentioned above may be a communication connection between the terminal and the new network. The original network may be, for example, a cellular network, and the new network may be, for example, a WiFi network. Alternatively, the original network may be, for example, a WiFi network, and the new network may be, for example, a cellular network, without limitation.

[0047] In the disclosed embodiments, "connection" may refer to a packet data network (IMS PDN) connection in an IP multimedia subsystem. "Connection" may also be referred to as a bearer, a signaling bearer (eg, an IMS signaling bearer), etc., without limitation.

[0048] In the embodiments of the present disclosure, a session may also be referred to as a call, without limitation thereto.

[0049] In the embodiments of the present disclosure, a data session may also be referred to as a data session, a voice session, a voice call, an IMS call, a call, etc., without limitation thereto.

[0050] like Figure 1B As shown, Figure 1B The diagram is a schematic diagram of an application scenario in an embodiment of the present disclosure. The terminal and the network device may interact. When the terminal switches the IMS signaling bearer between the cellular network and the WiFi network, if the terminal has a data session, the terminal may switch the IMS signaling bearer between the cellular network and the WiFi network. Figure 1B The interface shown in: (1) or (2) initiates an IMS PDN handover to the target network (WiFi network or cellular network), and carries a flag indicating that a data session is being handed over. After receiving a handover request with a data session, if the IMS PDN can be handed over and the data session can be maintained, the network notifies the terminal of a successful handover; if the network can handover the IMS PDN but cannot maintain the data session, the handover is not performed, and the terminal is notified of an IMS PDN handover failure, with a cause value indicating that the IMS session handover failed, and the terminal is responsible for maintaining the session, such as staying in the original network when the original network is available, or finding another available network to maintain the session.

[0051] Figure 2 A flow chart of a communication control method provided by an embodiment of the present disclosure.

[0052] like Figure 2 As shown, the communication control method includes:

[0053] Step S201: Send first information, wherein the first information at least includes: a request type, the request type is used to request switching from a first connection to a second connection, and the first connection includes: a data session.

[0054] The first information is used to indicate information requesting network switching. The first information may include a request type, and the request type is used to request switching from the first connection to the second connection. That is, the purpose of sending the first information is to request switching from the first connection to the second connection.

[0055] Optionally, in some embodiments, the terminal may send first information to the network device, where the network device refers to a network device in the new network, to request switching to the second connection in the new network. For example, the terminal may send an IMS PDN connection request to the network device, and carry the first information in the IMS PDN connection request to indicate to the network device a request to switch from the first connection to the second connection (i.e., handover), and may also indicate to the network device through the first information that the first connection includes: a data session, i.e., the first connection between the terminal and the original network contains an ongoing data session.

[0056] Optionally, in some embodiments, the network device may learn, based on the first information indicated by the terminal, that the terminal requests to switch from the first connection to the second connection, and learn that the first connection between the terminal and the original network includes an ongoing data session.

[0057] Optionally, in some embodiments, the network device may determine whether the device can support maintaining the data session based on the various contents learned above, and indicate whether the device can support maintaining the data session to the terminal through the second information.

[0058] Optionally, in some embodiments, the reason why the network device does not support maintaining a data session may be, for example, that the network device cannot assign the same address to the second connection as the first connection, or it may be any other possible reason related to the implementation on the network device side, which is not limited.

[0059] The address may be, for example, an Internet Protocol (IP) address.

[0060] Optionally, in some embodiments, if the network device is able to assign the same address as the first connection to the second connection, the network device may support maintaining the data session, without limitation.

[0061] Optionally, in some embodiments, if the network device does not support maintaining a data session, the network device may indicate a handover failure and set the reason for the handover failure to: session handover failure. If the network device supports maintaining a data session, the network device may indicate a handover success.

[0062] Step S202: Receive second information, where the second information is used to indicate whether to support maintaining the data session.

[0063] The second information is used to indicate whether the data session is supported. For example, the second information is used to indicate whether the network device supports maintaining the data session, or the second information is used to indicate that the network device does not support maintaining the data session.

[0064] That is, the network device may feed back the second information to the terminal to indicate whether the network device supports maintaining the data session, and the terminal may receive the second information sent by the network device to learn whether the network device supports maintaining the data session.

[0065] Optionally, in some embodiments, if the network device supports maintaining a data session, the network device may feedback a message indicating a successful switch, and carry second information in the message indicating a successful switch, so that the terminal can promptly learn that the network device supports maintaining a data session.

[0066] Optionally, in some embodiments, if the network device does not support maintaining data sessions, the network device may feedback a message indicating a switching failure, and carry second information in the message indicating the switching failure, so that the terminal can promptly learn that the network device does not support maintaining data sessions.

[0067] Step S203: Determine whether to switch from the first connection to the second connection according to the second information.

[0068] Optionally, in some embodiments, the terminal may receive second information fed back by the network device, and determine whether to switch from the first connection to the second connection based on the second information.

[0069] Optionally, in some embodiments, the terminal can receive a message indicating a successful handover fed back by the network device, and the terminal can also parse the message indicating a successful handover to obtain the second information. If the terminal can receive a message indicating a successful handover fed back by the network device, and / or the terminal can parse the message indicating a successful handover to obtain the second information, the terminal can effectively learn that the network device supports maintaining the data session. At this time, if the data call can still be maintained by switching to the second connection, the terminal can switch from the first connection to the second connection. This ensures the continuity of the data session.

[0070] Optionally, in some embodiments, the terminal can receive a message indicating a switching failure fed back by the network device, and the terminal can also parse the second information from the message indicating the switching failure. If the terminal can receive a message indicating a switching failure fed back by the network device, and / or the terminal can parse the second information from the message indicating the switching failure, the terminal can effectively know that the network device does not support maintaining the data session. At this time, if switching to the second connection will cause the data call to be disconnected, the terminal may not trigger the switching from the first connection to the second connection, but take any other possible way to ensure the continuity of the data call, thereby ensuring the continuity of the data session.

[0071] In this embodiment, by sending the first information, wherein the first information at least includes: a request type, the request type is used to request a switch from the first connection to the second connection, the first connection includes: a data session, and receiving the second information, wherein the second information is used to indicate whether to support maintaining the data session, and according to the second information, determining whether to switch from the first connection to the second connection. Thus, when requesting to switch networks, the first connection before the switch includes the data session is indicated to the new network, and based on the second information indicated by the new network, it is learned whether the new network supports maintaining the data session. When determining whether to switch from the first connection to the second connection based on the second information, the continuity of the data session can be ensured and the communication effect can be improved.

[0072] Optionally, in some embodiments, the first information further includes: first address information, wherein the first address information is used to indicate the address of the first connection. Thus, the network side can determine whether the device can allocate the same address as the first connection to the second connection based on the address of the first connection, so that the network device can quickly determine whether the device can support maintaining the data call.

[0073] Figure 3 A flowchart of another communication control method provided by an embodiment of the present disclosure.

[0074] like Figure 3 As shown, the communication control method includes:

[0075] Step S301: Send first information, wherein the first information at least includes: a request type, the request type is used to request switching from a first connection to a second connection, and the first connection includes: a data session.

[0076] Step S302: Receive second information, where the second information is used to indicate support for maintaining a data session.

[0077] Optionally, in this embodiment, the second information may indicate support for maintaining a data session, and the second information may include the following items: first indication information, second indication information, and third indication information; wherein the first indication information indicates support for establishing a second connection; the second indication information indicates second address information, the second address information is used to indicate an address allocated for the second connection, and the first address information and the second address information are the same; the third indication information indicates that the network switching is successful. Thus, the terminal can timely and accurately learn that the network device supports maintaining a data session, and supports improving the efficiency of the switching.

[0078] Step S303: Switch from the first connection to the second connection according to the second address information.

[0079] Optionally, in some embodiments, if the terminal learns that the network device supports maintaining the data session, that is, if the data call can still be maintained after switching to the second connection, the terminal can switch from the first connection to the second connection, thereby ensuring the continuity of the data session.

[0080] Optionally, in some embodiments, the terminal can switch from the first connection to the second connection according to the second address information. Thus, fast and accurate switching of the connection is achieved, thereby comprehensively improving the communication effect. For example, the terminal can establish a second connection with the new network according to the second address information.

[0081] Step S304: Conduct a data session based on the second connection.

[0082] Optionally, in some embodiments, after the terminal switches from the first connection to the second connection, the terminal can conduct a data session based on the second connection. Since the network device supports maintaining the data session, the terminal can continue the data session on the second connection without interruption, thereby ensuring the continuity of the data session and improving the communication effect.

[0083] Optionally, in some embodiments, after switching from the first connection to the second connection, the terminal may initiate an IMS refresh registration to continue the data session.

[0084] In this embodiment, by sending the first information, wherein the first information at least includes: a request type, the request type is used to request to switch from the first connection to the second connection, the first connection includes: a data session, and receiving the second information, wherein the second information is used to indicate support for maintaining the data session, according to the second address information, the first connection is switched to the second connection, and the data session is conducted based on the second connection. In this way, it can be effectively known that the network device supports maintaining the data session. At this time, if the data call can still be maintained by switching to the second connection, the first connection can be switched to the second connection, and the data session can be conducted based on the second connection. In this way, the continuity of the data session is ensured and the communication effect is improved. And according to the second address information, the first connection can be switched to the second connection. In this way, the connection is switched quickly and accurately, thereby comprehensively improving the communication effect.

[0085] Figure 4 A flowchart of another communication control method provided by an embodiment of the present disclosure.

[0086] like Figure 4 As shown, the communication control method includes:

[0087] Step S401: Send first information, wherein the first information at least includes: a request type, the request type is used to request switching from a first connection to a second connection, and the first connection includes: a data session.

[0088] Step S402: Receive second information, where the second information is used to indicate that maintaining a data session is not supported.

[0089] Optionally, in some embodiments, the second information indicates that the data session is not supported, and the second information includes the following items: first indication information and fourth indication information; wherein the first indication information indicates that the second connection is supported; and the fourth indication information indicates that the session switching fails. Thus, the terminal can timely and accurately learn that the network device does not support the maintenance of the data session, so as to take timely countermeasures to ensure the continuity of the data session.

[0090] Step S403: Execute the target operation to maintain the data session.

[0091] Optionally, in some embodiments, when the terminal learns that the second information indicates that maintaining the data session is not supported, the terminal may perform the target operation to maintain the data session.

[0092] Optionally, in some embodiments, in the process of performing the target operation to maintain the data session, the data session in the first connection may be maintained if the first connection supports maintaining the data session. In other words, if the first connection can still effectively support the normal progress of the data session, the first connection may be maintained to conduct the data session based on the first connection.

[0093] Optionally, in some embodiments, in the process of performing the target operation to maintain the data session, when the first connection does not support maintaining the data session, the first connection is switched to a third connection in the available network, and the data session is performed based on the third connection. In other words, if the first connection cannot continue to support the normal progress of the data session, an escape operation can be performed to connect to the third connection in another available network, and the data session is performed based on the third connection.

[0094] Optionally, in some embodiments, in the process of performing the target operation to maintain the data session, the data session may be released and the first information may be resent if the first connection does not support maintaining the data session and the switch to the third connection is unsuccessful. In other words, if the first connection cannot continue to support the normal progress of the data session and the switch to the third connection in the available network is unsuccessful, the data session may be released and the first information may be resent.

[0095] Therefore, when it is known that the network device does not support maintaining the data session, various possible countermeasures can be taken to maximize the continuity of the data session, which can be effectively applied to personalized communication scenarios and support improving the user session usage experience.

[0096] In this embodiment, by sending the first information, wherein the first information at least includes: a request type, the request type is used to request switching from the first connection to the second connection, the first connection includes: a data session, and receiving the second information, wherein the second information is used to indicate that maintaining the data session is not supported, and performing the target operation to maintain the data session. Thus, it can be effectively learned that the network device does not support maintaining the data session, and at this time, the target operation can be performed to maintain the data session. In this way, the continuity of the data session is ensured and the communication effect is improved.

[0097] It should be noted that, in the following embodiments, the description of the terms and method steps that are the same as or corresponding to those in the above embodiments can be specifically referred to in the above embodiments, and will not be repeated here.

[0098] Figure 5A flowchart of another communication control method provided by an embodiment of the present disclosure.

[0099] like Figure 5 As shown, the communication control method includes:

[0100] Step S501: Receive first information, wherein the first information at least includes: a request type, the request type is used to request switching from a first connection to a second connection, and the first connection includes: a data session.

[0101] Optionally, in some embodiments, the network device may receive the first information sent by the terminal.

[0102] Optionally, in some embodiments, the network device may learn, based on the first information indicated by the terminal, that the terminal requests to switch from the first connection to the second connection, and learn that the first connection between the terminal and the original network includes an ongoing data session.

[0103] Step S502: Determine whether to support maintaining the data session according to the first information.

[0104] Optionally, in some embodiments, the network device may determine whether the device can support maintaining the data session based on the various contents learned above, and indicate whether the device can support maintaining the data session to the terminal through the second information.

[0105] Optionally, in some embodiments, the reason why the network device does not support maintaining a data session may be, for example, that the network device cannot assign the same address to the second connection as the first connection, or it may be any other possible reason related to the implementation on the network device side, which is not limited.

[0106] The address may be, for example, an Internet Protocol (IP) address.

[0107] Optionally, in some embodiments, if the network device is able to assign the same address as the first connection to the second connection, the network device may support maintaining the data session, without limitation.

[0108] Step S503: Send second information, wherein the second information is used to indicate whether to support maintaining the data session, and the second information is used to determine whether to switch from the first connection to the second connection.

[0109] Optionally, in some embodiments, if the network device does not support maintaining a data session, the network device may indicate a handover failure and set the reason for the handover failure to: session handover failure. If the network device supports maintaining a data session, the network device may indicate a handover success.

[0110] Optionally, in some embodiments, if the network device supports maintaining a data session, the second information may indicate support for maintaining the data session. In this case, the second information may include the following items: first indication information, second indication information, and third indication information; wherein the first indication information indicates support for establishing a second connection; the second indication information indicates second address information, the second address information is used to indicate an address allocated for the second connection, and the first address information and the second address information are the same; the third indication information indicates that the network switching is successful. Thus, it is possible to timely and accurately indicate the situation in which the network device supports maintaining a data session, and support improving the efficiency of switching.

[0111] Optionally, in some embodiments, if the network device does not support maintaining the data session, the second information may be used to indicate that the data session is not supported. In this case, the second information may include the following items: first indication information and fourth indication information; wherein the first indication information indicates that the second connection is supported; and the fourth indication information indicates that the session switching fails. Thus, the situation that the network device does not support maintaining the data session can be indicated in a timely and accurate manner, so as to take timely countermeasures to ensure the continuity of the data session.

[0112] In this embodiment, by receiving the first information, wherein the first information at least includes: a request type, the request type is used to request to switch from the first connection to the second connection, the first connection includes: a data session, and according to the first information, it is determined whether to support maintaining the data session, and the second information is sent, wherein the second information is used to indicate whether to support maintaining the data session, and the second information is used to determine whether to switch from the first connection to the second connection. Thus, it can be effectively known that the first connection before the switch includes the data session, and whether to support maintaining the data session is indicated by the second information. When it is determined based on the second information whether to switch from the first connection to the second connection, the continuity of the data session can be ensured and the communication effect can be improved.

[0113] The examples for the above embodiment are as follows:

[0114] The data session is taken as an example of the interaction between a voice call, a terminal and a network device, but is not limited to this.

[0115] like Figure 6 As shown, Figure 6 It is a schematic diagram of a voice call process in an embodiment of the present disclosure. Figure 6 The figure shows the process of switching the IMS signaling bearer between the cellular network and the WiFi network.

[0116] S601: The terminal registers on a cellular network or a WiFi network and establishes a voice call.

[0117] S602: The terminal sends an IMS PDN connection request (including request type: handover, and there is an ongoing voice call) to the network device.

[0118] The request type is used to indicate "switching, and there is an ongoing voice call", which is an optional example of the above "the request type is used to request switching from a first connection to a second connection, and the first connection includes: a data session".

[0119] S603: If the network device supports switching to IMS PDN, the voice call can continue (the same IP address is assigned), and the switching is triggered to feedback a message indicating that the switching is successful.

[0120] The "message for indicating a successful handover" may be, for example, a message for accepting an IMS PDN connection request.

[0121] S604: The network device sends a message of "accepting the IMS PDN connection request" (including the allocated IP address) to the terminal.

[0122] S605: The terminal is switched successfully, an IMS refresh registration is initiated, and the voice call continues.

[0123] The above steps S603-S605 may be scenario 1 "IMS PDN handover is successful".

[0124] S606: If the network device supports switching to the IMS PDN, but the voice call cannot be continued (including that the same IP address cannot be allocated), a message indicating a switching failure is triggered and fed back.

[0125] The "message for indicating a handover failure" may be, for example, a message for rejecting the IMS PDN connection request.

[0126] S607: The network device sends a "message of rejecting the IMS PDN connection request" to the terminal (including the failure reason: IMS session switching failure).

[0127] S608: The terminal fails to process the IMS session handover.

[0128] Optionally, in some embodiments, the terminal may stay in the original domain, or perform an escape operation to keep the voice call going, or may release the voice call and re-initiate a handover request.

[0129] The above steps S606 to S608 may be scenario 2 "IMS session handover failure".

[0130] S609: If the network device does not support switching the IMS PDN, a message indicating a switching failure is triggered to be fed back.

[0131] S610: The network device sends a "message of rejecting the IMS PDN connection request" to the terminal (including the failure reason: IMS PDN switching failure).

[0132] S611: The terminal fails to process the IMS PDN handover.

[0133] The above steps S609-S611 may be scenario 3 "IMS PDN handover failure".

[0134] In the above S602, the terminal may indicate to the network device that the IMS PDN request type is a handover with a voice call, so that when the network device processes the handover, it returns a handover success or handover failure according to whether the voice call can be maintained.

[0135] In the above scenarios 1 and 2, the network device returns a successful handover if the IMS call can be maintained to keep the voice call going. If the network device can switch the IMS PDN but cannot ensure the continuity of the voice call, it returns a failed handover and the terminal ensures the continuity of the voice call.

[0136] like Figure 7 As shown, Figure 7 It is another schematic diagram of a voice call process in an embodiment of the present disclosure. Figure 7 The figure shows the process of switching the IMS signaling bearer from the cellular network to the WiFi network.

[0138] S702: The terminal sends an IKE_AUTH request message to the network device (including: IP address, request type: handover, and an ongoing voice call).

[0139] Among them, the IKE_AUTH request message can be used for authentication and key exchange.

[0140] S703: If the network device supports switching to IMS PDN, the voice call can continue (the same IP address is assigned), and the switching is triggered to feedback a message indicating that the switching is successful.

[0141] The "message for indicating successful switching" may be, for example, an IKE_AUTH response message.

[0142] S704: The network device sends an "IKE_AUTH response message" (including the allocated IP address) to the terminal.

[0143] S705: The terminal is switched successfully, an IMS refresh registration is initiated, and the voice call continues.

[0144] The above steps S703-S705 may be scenario 1 "IMS PDN switching is successful".

[0145] S706: If the network device supports switching to the IMS PDN, but the voice call cannot be continued (including that the same IP address cannot be allocated), a message indicating a switching failure is triggered and fed back.

[0146] The “message for indicating a switching failure” may be, for example, an IKE_AUTH response message.

[0147] S707: The network device sends an "IKE_AUTH response message" (including the failure reason: IMS session switching failure) to the terminal.

[0148] S708: The terminal fails to process the IMS session handover.

[0149] Optionally, in some embodiments, the terminal may stay in the original domain, or perform an escape operation to keep the voice call going, or may release the voice call and re-initiate a handover request.

[0150] The above steps S706 to S708 may be scenario 2 "IMS session handover failure".

[0151] S709: If the network device does not support switching the IMS PDN, a message indicating a switching failure is triggered to be fed back.

[0152] S710: The network device sends an "IKE_AUTH response message" (including the failure reason: IMS PDN switching failure) to the terminal.

[0158] S803: If the network device supports switching to IMS PDN, the voice call can continue (the same IP address is assigned), and the switching is triggered to feedback a message indicating that the switching is successful.

[0159] The “message for indicating a successful handover” may be, for example, an activate default EPS bearer context request message (Activate default EPS bearer context request).

[0160] S804: The network device sends an "activate default EPS bearer context request message" (including the allocated IP address) to the terminal.

[0161] Optionally, the terminal may feed back an activate default EPS bearer context accept message (ActivatedefaultEPS bearer context accept) to the network device.

[0162] S805: The terminal is switched successfully, an IMS refresh registration is initiated, and the voice call continues.

[0163] The above steps S803-S805 may be scenario 1 "IMS PDN switching is successful".

[0165] The "message for indicating a switching failure" may be, for example, a PDN connection rejection message.

[0166] S807: The network device sends a "PDN connection rejection message" to the terminal (including the failure reason: IMS session handover failure).

[0167] S808: The terminal fails to process the IMS session handover.

[0168] Optionally, in some embodiments, the terminal may stay in the original domain, or perform an escape operation to keep the voice call going, or may release the voice call and re-initiate a handover request.

[0169] The above steps S806-S808 may be scenario 2 "IMS session handover failure".
