[0054] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0055] Figure 1 This is a schematic diagram of the architecture of the fusion network according to an embodiment of the present invention; as shown Figure 1 As shown, the converged network used in this embodiment of the invention includes: multiple connected terminals (also referred to as terminals, terminal devices, communication terminals, etc.), access network, converged core network (also referred to as core network), converged voice network (also referred to as voice network), and audio and video service platform (also referred to as media service platform, service platform, etc.).

[0056] The access network includes at least two of the following: fixed access network, mobile access network, and satellite access network. Each access network can also be divided into multiple access networks based on different frequency ranges. For example... Figure 1 As shown, the satellite access network may include satellite access network D and satellite access network E, and the mobile access network may include mobile access network B and mobile access network C. It should be noted that... Figure 1 The number of access networks shown is merely an example for scenario illustration; in actual applications, the number of access networks in each type of access network is not limited to this. Figure 1 As shown in the image.

[0057] The multi-connection terminal in this embodiment supports fixed, mobile, and satellite multi-connection capabilities, and supports scenarios such as switching between fixed and mobile access networks, switching between mobile and mobile access networks, switching between fixed and satellite access networks, switching between mobile and satellite access networks, and switching between satellite access networks. The multi-connection terminal supports multiple voice / video codecs and multiple voice / video rate levels, and supports switching between voice calls and video calls, as well as switching between voice calls with multiple codecs / rate levels and switching between video calls with multiple codecs / rate levels.

[0058] For example, the access equipment of a mobile access network can be a base station in a communication network such as GSM (Global System for Mobile communication), CDMA (Code Division Multiple Access), LTE (Long Term Evolution), or 5G. 5G systems can also be called New Radio (NR) systems.

[0059] The audio and video service platform provides audio and video services and value-added audio and video services (such as supplementary services, intelligent networks, and ringback tones). It supports multiple voice / video codecs and multiple voice / video rate levels, and supports switching between voice calls and video calls, as well as switching between voice calls with multiple codecs / rate levels and video calls with multiple codecs / rate levels.

[0060] Service continuity refers to methods for maintaining the continuous use of services by multiple connected terminals when connection handover is initiated on the network side or the user side. Since the 3G era, audio and video service continuity has been a crucial technological direction in the communications field. With the advent of the 4G / 5G era, the rapid development of VoLTE / VoNR services has placed even higher demands on audio and video service continuity. Audio and video service continuity has become a vital component for ensuring the quality of audio and video services and user experience, and it holds significant practical importance. Addressing the needs of multi-access converged services, achieving audio and video service continuity in fixed, mobile, and satellite converged networks has significant application value and is fundamental to ensuring the quality of audio and video services and user experience for multiple connected terminals.

[0061] Business continuity in this embodiment includes, for example: Figure 1 The scenario shown refers to at least one of the following scenarios: S1: handover scenario between fixed and mobile access networks, S2: handover scenario between mobile and mobile access networks, S3: handover scenario between fixed and satellite access networks, S4: handover scenario between mobile and satellite access networks, and S5: handover scenario between satellite and satellite access networks.

[0062] At least based on Figure 1 The following embodiments of the present invention are proposed based on the scenario shown.

[0063] This invention provides a method for ensuring service continuity in converged networks. Figure 2 A flowchart illustrating the service continuity method for converged networks according to an embodiment of the present invention. Figure 1 ;like Figure 2 As shown, the method includes:

[0064] Step 101: The core network equipment determines the service rules corresponding to the terminal; the service rules include processing rules for audio and / or video services whose switching target is at least one of fixed access network, mobile access network and satellite access network;

[0065] Step 102: When the core network device receives an access handover event initiated by the terminal or network device, it determines the first handover target corresponding to the access handover event, determines the first processing rule for the first handover target based on the service rules, and performs service handover processing according to the first processing rule.

[0066] In various embodiments of the present invention, the business rules may also be referred to as rules, policies, business strategies, etc. This embodiment does not limit the name of the business rules, as long as they can achieve the function of the business rules. For example, the business rules are used to represent processing rules, processing methods, or processing strategies for audio and / or video services whose switching target is at least one of the following: fixed access network, mobile access network, and satellite access network. The switching target may also be referred to as a switching object, etc., indicating the access network to which the terminal is to switch access when an access switching event occurs. This embodiment does not limit the name of the switching target.

[0067] In this embodiment, the business rules include processing rules for the audio and / or video services corresponding to the switching target. For example, the business rules may include processing rules for the audio service corresponding to the switching target, or processing rules for the video service corresponding to the switching target, or processing rules for both audio and video services corresponding to the switching target, etc.

[0068] For example, the processing rules include the switching target and the corresponding voice and / or video communication capability level or voice and / or video rate level, etc. When the core network device receives an access switching event initiated by the terminal or network device, that is, when it determines that the terminal's access type or connection type has changed, it determines that the first switching target corresponding to the access switching event is at least one of a fixed access network, a mobile access network, or a satellite access network. Then, based on the service rules, it determines the first processing rule for the first switching target and performs service switching processing according to the first processing rule.

[0069] The access handover event is not limited to handover between access networks, such as handover between a fixed access network and a mobile access network, or between a mobile access network and a satellite access network, or between a fixed access network and a satellite access network; it can also be a handover within an access network, for example... Figure 1 As shown, this includes handover between satellite access network D and satellite access network E, handover between mobile access network B and mobile access network C, etc.

[0070] In some optional embodiments, the access handover event may be initiated by a terminal, in which case the core network device receives a message or signaling from the terminal representing the access handover event. In other optional embodiments, the access handover event may be initiated by a network device, in which case the core network device receives a message or signaling from the network device representing the access handover event, which may correspond to one or more terminal devices.

[0071] In some optional embodiments of the present invention, the core network device determines the service rules corresponding to the terminal, including: the core network device receiving setting information from the terminal via the voice network device, the setting information including at least one of the following: a first set of voice communication capability levels acceptable to the user, a first set of video communication capability levels acceptable to the user, priority information of voice and video communication capability levels, and information indicating whether the access type is maintained; the core network device obtaining connection-related information of the terminal; the connection-related information including connection type and connection rate information corresponding to the connection type; and the core network device determining the service rules based on the connection-related information and the configuration information.

[0072] In this embodiment, the user manually configures the above settings information on the terminal. The settings information can also be called configuration information, which indicates the user's preferences for audio and video calls when conducting audio and video services. In this embodiment, the name of the settings information is not limited. The setting information may include a first set of acceptable voice communication capability levels for the user, i.e., the acceptable voice communication capability levels for the user within the audio and video communication capability range of multiple connected terminals; the setting information may also include a first set of acceptable video communication capability levels for the user, i.e., the acceptable video communication capability levels for the user within the audio and video communication capability range of multiple connected terminals; the setting information may also include priority information for each voice / video capability level, for example, priority sorted from high to low as Video Class 3, Video Class 2, Voice Class 3, Voice Class 2, etc.; the setting information may also include information indicating whether the access type is maintained, also known as the media type retention option. When the media type retention option is enabled, the media type is kept unchanged during switching, i.e., information indicating access type retention. For example, if a call is initiated by voice, the voice call is maintained first after the connection switch; if a call is initiated by video, the video call is maintained first after the connection switch. When the media type retention option is disabled, the media type is not maintained first during switching, i.e., information indicating access type is not maintained. The voice network device receives the above-mentioned setting information from the terminal, saves the setting information, and sends the setting information to the core network device.

[0073] In this embodiment, the connection-related information of the terminal includes the terminal's connection type and / or typical connection rate value. For example, the typical connection rate value is empirical data on the connection rate of the terminal using the corresponding connection type in its network environment. The core network device determines service rules based on the setting information and the terminal's connection-related information, for connection switching initiated by the terminal and connection switching initiated by the network.

[0074] In some optional embodiments, the first voice communication capability level set includes one or more voice communication capability levels; the voice communication capabilities supported by the terminal are pre-divided into multiple voice communication capability levels. The first video communication capability level set includes one or more video communication capability levels; the video communication capabilities supported by the terminal are pre-divided into multiple video communication capability levels.

[0075] For example, the first set of voice communication capability levels includes multiple voice communication capability levels, such as: Voice Class 1 (corresponding to a low-speed voice communication capability level), Voice Class 2 (corresponding to a medium-speed voice communication capability level), and Voice Class 3 (corresponding to a high-speed voice communication capability level). For example, the first set of video communication capability levels includes multiple voice communication capability levels, such as: Video Class 1 (corresponding to a low-speed video communication capability level), Video Class 2 (corresponding to a medium-speed video communication capability level), and Video Class 3 (corresponding to a high-speed video communication capability level).

[0076] In some alternative embodiments, the connection type includes: fixed access network connection, mobile access network connection, or satellite access network connection. In this embodiment, the connection type represents the terminal's current connection type or access type.

[0077] In some optional embodiments of the present invention, the core network device determines the service rules based on the access-related information and the configuration information, including: the core network device determines the following processing rules based on the connection type, the connection rate information corresponding to the connection type, and the configuration information:

[0078] When the target of the switch is a fixed access network, the audio communication capability level or the video communication capability level is selected.

[0079] When the target of the switch is a mobile access network, the audio communication capability level or the video communication capability level is selected.

[0080] Switching the target to the audio communication capability level or video communication capability level when the target is a satellite access network.

[0081] For example, the communication capabilities of terminal 1 include: Voice Class 1, Voice Class 2, Voice Class 3, Video Class 1, Video Class 2, and Video Class 3; the settings information of terminal 1 includes: the user's acceptable voice communication capability levels include: Voice Class 1, Voice Class 2, and Voice Class 3; the user's acceptable video communication capability levels include: Video Class 2 and Video Class 3; the priority information of each voice / video capability level is: Video Class 3, Video Class 2, Voice Class 3, Voice Class 2, and Voice Class 1 (ordered from high to low priority); the media type retention option is turned off (i.e., information indicating that the access type is not retained).

[0082] The communication capabilities of Terminal 2 include: Voice Class 1, Voice Class 2, Video Class 1, and Video Class 2; the settings of Terminal 2 include: the user's acceptable voice communication capability levels include: Voice Class 1 and Voice Class 2; the user's acceptable video communication capability levels include: Video Class 1 and Video Class 2; the priority information of each voice / video capability level is: Voice Class 2, Voice Class 1, Video Class 2, and Video Class 1 (ordered from high to low priority); the media type retention option is enabled (i.e., information indicating access type retention).

[0083] Terminal 1 supports fixed access networks, 2G mobile access networks, 4G mobile access networks, 5G mobile access networks, and satellite access networks. Typical fixed access rates are 100 Mbit / s downlink and 20 Mbit / s uplink; typical 2G mobile access rates are 200 Kbit / s downlink and 60 Kbit / s uplink; typical 4G mobile access rates are 40 Mbit / s downlink and 8 Mbit / s uplink; typical 5G mobile access rates are 300 Mbit / s downlink and 60 Mbit / s uplink; and typical satellite access rates are 5 Mbit / s downlink and 500 Kbit / s uplink. Based on User 1's settings, Terminal 1's service rules are as follows:

[0084] Switching target to fixed access: Maintain or switch to Video Class 3;

[0085] Switching target to 2G mobile access: Maintain or switch to Voice Class 1;

[0086] Switching target to 4G mobile access: Maintain or switch to Video Class 2;

[0087] Switching target to 5G mobile access: Maintain or switch to Video Class 3;

[0088] Switching target to satellite access: Maintain or switch to Voice Class 3.

[0089] Terminal 2 supports fixed access networks, 2G mobile access networks, 4G mobile access networks, and satellite access networks. Typical fixed access rates are 40 Mbit / s downlink and 8 Mbit / s uplink; typical 2G mobile access rates are 200 Kbit / s downlink and 60 Kbit / s uplink; typical 4G mobile access rates are 20 Mbit / s downlink and 4 Mbit / s uplink; and typical satellite access rates are 500 Kbit / s downlink and 50 Kbit / s uplink. Based on user 2's settings, the service rules for terminal 2 are as follows:

[0090] Switching target to fixed access: Initiating a call with voice, maintain or switch to Voice Class 2; initiating a call with video, maintain or switch to Video Class 2.

[0091] When switching to 2G mobile access: if a call is initiated by voice, maintain or switch to Voice Class 1; if a call is initiated by video, maintain or switch to Voice Class 1.

[0092] Switching target to 4G mobile access: Initiating a call with voice, maintain or switch to Voice Class 2; initiating a call with video, maintain or switch to Video Class 2.

[0093] Switching the target to satellite access: Initiating a call with voice, maintain or switch to Voice Class 1; Initiating a call with video, maintain or switch to Voice Class 1.

[0094] In some optional embodiments of the present invention, the step of performing service switching processing according to the first processing rule includes: the core network device generating a service switching instruction based on the first processing rule, sending the service switching instruction to the voice network device, and sending the service switching instruction to the terminal.

[0095] In this embodiment, when a connection switch is initiated by the user or the network, the core network device receives the access switch event from the terminal, determines the first switch target corresponding to the access switch event, determines the first processing rule for the first switch target based on the service rules, and generates a service switch instruction based on the first processing rule.

[0096] Optionally, the service switching instruction includes at least a first audio communication capability level or a first video communication capability level corresponding to the first switching target; the first audio communication capability level or the first video communication capability level is used to instruct the media service platform and the terminal to communicate.

[0097] Optionally, the service switching unit in the core network equipment is used to perform operations such as determining service rules and service switching. For example, the service switching unit can be deployed in existing network functions (such as 5GPCF / IMT-2020PCF) or as a new network function, and can support the synchronization of terminal connection type and typical connection rate information with the terminal.

[0098] Based on the above embodiments, this invention also provides a method for ensuring service continuity in converged networks. Figure 3 A flowchart illustrating the service continuity method for converged networks according to an embodiment of the present invention. Figure 2 ;like Figure 3 As shown, the method includes:

[0099] Step 201: The voice network device receives setting information from the terminal, the setting information including at least one of the following: a first set of voice communication capability levels that the user can accept, a first set of video communication capability levels that the user can accept, priority information of voice and video communication capability levels, and information indicating whether the access type is maintained; the setting information is used to determine the service rules for guiding service switching processing;

[0100] Step 202: The voice network device sends the setting information to the core network device.

[0101] In this embodiment, the user manually configures the above settings information on the terminal. The settings information can also be called configuration information, which represents the user's preferences for audio and video calls when conducting audio and video services. The setting information may include a first set of acceptable voice communication capability levels for the user, i.e., the acceptable voice communication capability levels within the terminal's audio and video communication capability range; the setting information may also include a first set of acceptable video communication capability levels for the user, i.e., the acceptable video communication capability levels within the terminal's audio and video communication capability range; the setting information may also include priority information for each voice / video capability level, for example, priority sorted from high to low as Video Class3, Video Class 2, Voice Class 3, Voice Class 2, etc.; the setting information may also include information indicating whether the access type is maintained, also known as the media type retention option. When the media type retention option is enabled, the media type is kept unchanged during switching, i.e., information indicating access type retention. For example, if a call is initiated with voice, the voice call is maintained after the connection switch; if a call is initiated with video, the video call is maintained after the connection switch. When the media type retention option is disabled, the media type is not maintained during switching, i.e., information indicating access type retention is not maintained.

[0102] In this embodiment, the voice network device receives the aforementioned setting information from the terminal through any access network (fixed access network, mobile access network, or satellite access network) and the core network. Upon receiving the setting information from the terminal, the voice network device saves the setting information and sends it to the core network device. Specifically, the voice network device includes a service capability unit capable of saving the aforementioned setting information. Optionally, the user can update the aforementioned setting information at any time through the terminal, and synchronize the updated setting information to the voice network device through any access network and the core network, and update the storage in the service capability unit.

[0103] For example, the service capability unit is used to perform the operations related to the above-mentioned configuration information. The service capability unit can be deployed on existing network functions (such as I / S-CSCF) or as a new network function, and supports the configuration of synchronizing the above-mentioned configuration information with the terminal.

[0104] In some optional embodiments of the present invention, before the voice network device receives setting information from the terminal, the method further includes: the voice network device dividing voice communication capabilities into multiple voice communication capability levels and video communication capabilities into multiple video communication capability levels according to media type and rate level.

[0105] In this embodiment, considering the differences in communication capabilities and resources among fixed access networks, mobile access networks, and satellite access networks, as well as the support capabilities of different multi-connection terminals and media service platforms for voice / video codecs and voice / video rate levels, the fixed, mobile, and satellite converged network needs to support multiple voice / video codecs and multiple voice / video rate levels. The voice network equipment classifies the voice communication capabilities and video communication capabilities according to the media type and rate level.

[0106] Optionally, the first set of voice communication capability levels includes one or more voice communication capability levels; the first set of video communication capability levels includes one or more video communication capability levels.

[0107] For example, the first set of voice communication capability levels includes multiple voice communication capability levels, such as: Voice Class 1 (corresponding to a low-speed voice communication capability level), Voice Class 2 (corresponding to a medium-speed voice communication capability level), and Voice Class 3 (corresponding to a high-speed voice communication capability level). For example, the first set of video communication capability levels includes multiple voice communication capability levels, such as: Video Class 1 (corresponding to a low-speed video communication capability level), Video Class 2 (corresponding to a medium-speed video communication capability level), and Video Class 3 (corresponding to a high-speed video communication capability level).

[0108] In some implementations, the voice network device pre-synchronizes multiple voice communication capability levels and multiple video communication capability levels to the terminal, or the terminal pre-writes the aforementioned multiple voice communication capability levels and multiple video communication capability levels, so that the user can configure the above settings information on the terminal. In other implementations, when or before the user configures the above settings information through the terminal, the terminal can establish a connection with the voice network device to obtain the multiple voice communication capability levels and multiple video communication capability levels pre-defined by the voice network device.

[0109] In some optional embodiments of the present invention, the service rules include the following processing rules: the audio communication capability level or video communication capability level when the terminal's handover target is a fixed access network; the audio communication capability level or video communication capability level when the terminal's handover target is a mobile access network; and the audio communication capability level or video communication capability level when the terminal's handover target is a satellite access network.

[0110] In some optional embodiments of the present invention, the method further includes: the voice network device receiving a service switching instruction from the core network device and sending the service switching instruction to the media service platform.

[0111] Optionally, the service switching instruction includes at least the first audio communication capability level or the first video communication capability level corresponding to the first switching target when the terminal's switching target is the first switching target; the first audio communication capability level or the first video communication capability level corresponding to the first switching target is used to instruct the media service platform to communicate.

[0112] The technical solution of this invention, in a first aspect, achieves service continuity in scenarios such as handover between fixed access networks and mobile access networks, handover between mobile access networks, handover between fixed access networks and satellite access networks, handover between mobile access networks and satellite access networks in a fixed, mobile, and satellite converged network.

[0113] Secondly, embodiments of the present invention can select the optimal media type in various switching scenarios according to the user's preferences. When the terminal switches to satellite access, 2G mobile access, or is in a weak coverage area, it can actively switch the video call to an audio call.

[0114] Thirdly, embodiments of the present invention can select the optimal rate level in various switching scenarios according to user preferences. When the terminal switches to satellite access, 2G mobile access, or is in a weak coverage area, it can actively switch high-speed calls to low-speed calls.

[0115] Fourthly, the embodiments of the present invention can generate service switching instructions according to the switching scenario and business rules, and perform service continuity operations during the switching based on the service switching instructions, effectively reducing information interaction between the terminal, voice network and media service platform during service switching.

[0116] The following describes the method for ensuring service continuity in a converged network according to an embodiment of the present invention, using specific examples.

[0117] Figure 4 This is a schematic diagram of the interaction flow of the service continuity method for converged networks according to an embodiment of the present invention; such as Figure 4 As shown, the method includes:

[0118] Step 300: Voice network equipment classifies audio and video communication capabilities according to media type and rate level.

[0119] Here, the service capability units in the voice network equipment classify audio and video communication capabilities according to media type and rate level. Specifically, voice communication capabilities can be divided into multiple voice communication capability levels, and video communication capabilities can be divided into multiple video communication capability levels.

[0120] For example, voice communication capabilities can be classified as: Voice Class 1 (corresponding to low-speed voice communication capability level), Voice Class 2 (corresponding to medium-speed voice communication capability level), and Voice Class 3 (corresponding to high-speed voice communication capability level). Video communication capabilities can be classified as: Video Class 1 (corresponding to low-speed video communication capability level), Video Class 2 (corresponding to medium-speed video communication capability level), and Video Class 3 (corresponding to high-speed video communication capability level).

[0121] Step 301: The user configures settings on the terminal, that is, the user's audio and video call preference settings.

[0122] Here, the settings include: a first set of voice communication capability levels that the user can accept (i.e., the user's acceptable voice communication capability level within the terminal's audio and video communication capability range), a first set of video communication capability levels that the user can accept (i.e., the user's acceptable video communication capability level within the terminal's audio and video communication capability range), priority information for voice and video communication capability levels, and information indicating whether the access type is maintained.

[0123] Step 302: The terminal will synchronize the settings information to the voice network equipment.

[0124] Here, the service capability unit of the voice network equipment obtains the setting information and saves the setting information.

[0125] Step 303: The voice network equipment synchronizes the settings information to the core network equipment.

[0126] Here, the service capability unit of the voice network equipment will synchronize the configuration information to the service switching unit of the core network equipment.

[0127] Step 304: The core network equipment determines the service rules based on the terminal's connection type, typical connection rate, and configuration information.

[0128] Here, the service switching unit of the core network equipment maps the configuration information to service rules based on the terminal's connection type and its typical connection rate.

[0129] For example, the terminal's communication capabilities include: Voice Class 1, Voice Class 2, Voice Class 3, Video Class 1, Video Class 2, and Video Class 3; the terminal's settings include: the user's acceptable voice communication capability levels include: Voice Class 1, Voice Class 2, and Voice Class 3; the user's acceptable video communication capability levels include: Video Class 2 and Video Class 3; the priority information for each voice / video capability level is: Video Class 3, Video Class 2, Voice Class 3, Voice Class 2, and Voice Class 1 (ordered from highest to lowest priority); the media type retention option is turned off (i.e., information indicating that the access type is not retained).

[0130] The terminal supports fixed access networks, 2G mobile access networks, 4G mobile access networks, 5G mobile access networks, and satellite access networks. Typical fixed access rates are 100 Mbit / s downlink and 20 Mbit / s uplink; typical 2G mobile access rates are 200 Kbit / s downlink and 60 Kbit / s uplink; typical 4G mobile access rates are 40 Mbit / s downlink and 8 Mbit / s uplink; typical 5G mobile access rates are 300 Mbit / s downlink and 60 Mbit / s uplink; and typical satellite access rates are 5 Mbit / s downlink and 500 Kbit / s uplink. Based on user settings, the terminal's service rules are as follows:

[0131] Switching target to fixed access: Maintain or switch to Video Class 3;

[0132] Switching target to 2G mobile access: Maintain or switch to Voice Class 1;

[0133] Switching target to 4G mobile access: Maintain or switch to Video Class 2;

[0134] Switching target to 5G mobile access: Maintain or switch to Video Class 3;

[0135] Switching target to satellite access: Maintain or switch to Voice Class 3.

[0136] Step 305: The terminal initiates a 5G mobile access to satellite access handover, and the core network equipment receives the event corresponding to the connection handover.

[0137] Step 306: The core network equipment determines the switching target as the satellite access network based on the event corresponding to the connection switching, determines the first processing rule based on the switching target as the satellite access network, and generates a service switching instruction based on the first processing rule.

[0138] Here, the service switching unit of the core network equipment generates a service switching instruction based on the switching scenario and service rules, and determines to switch from Video Class 3 to Voice Class 3 according to the above service rule example.

[0139] The service switching instruction may include a connection type of satellite access and Voice Class 3.

[0140] Step 307: The core network equipment synchronizes the service switching command to the voice network equipment.

[0141] Here, the service switching unit in the core network equipment synchronizes the service switching command to the voice network equipment.

[0142] Step 308: The voice network equipment synchronizes the service switching command to the media service platform.

[0143] Step 309: The core network equipment synchronizes the service switching command to the terminal.

[0144] Here, the service switching unit in the core network equipment synchronizes the service switching command to the terminal.

[0145] It should be noted that the execution order of steps 307 and 309 is not limited to that shown above. Step 309 can be executed first and then step 307, or steps 307 and 309 can be executed simultaneously. This embodiment does not limit this.

[0146] Step 310: The terminal, voice network equipment, and media service platform conduct audio and video calls using the switched media type and rate class (Voice Class 3).
