[0045] The embodiments of the present disclosure provide a communication method and apparatus, a communication device, a communication system, and a storage medium.

[0046] In a first aspect, an embodiment of the present disclosure provides a communication method, performed by a network device, comprising at least one of the following:

[0047] The network device receives first measurement data and / or second measurement data reported by the terminal; wherein the first measurement data is measurement data corresponding to the first network, and the second measurement data is measurement data corresponding to the second network; the first network and the second network can be used to implement different types of voice services respectively;

[0048] determining a target network based on the first measurement data and / or the second measurement data, where the target network is the first network or the second network, and the target network is a network to which the terminal is to be connected, as determined by the network device;

[0049] First information is sent to the terminal, where the first information is used to indicate the target network.

[0050] In the above embodiment, the network device can determine a target network from the first network and the second network based on the first measurement data and / or the second measurement data reported by the terminal, and indicate the target network to the terminal so that the terminal can connect to the target network. The first network and the second network can each be used to implement different types of voice services. Therefore, it can be seen that in the embodiments of the present disclosure, the network device can decide whether to trigger the terminal to switch to different networks for implementing different types of voice services (e.g., the network device decides whether to trigger the terminal to switch to a WLAN or a cellular network). Compared to the related art, in which only the terminal can decide whether to switch to a WLAN or a cellular network, the present disclosure provides a new method for deciding whether to switch to a WLAN or a cellular network, thereby improving the flexibility of switching between WLAN and cellular networks. Furthermore, in the present disclosure, when the network device is used to decide whether to trigger the switch between the WLAN and cellular networks, because the network device has higher capabilities (such as software and hardware capabilities, computing power, etc.) than the terminal, the decision made by the network device is more accurate, thereby ensuring handover accuracy, avoiding unnecessary handovers, and improving communication quality.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the first network is a wireless local area network (WLAN), and the second network is a cellular network; or, the first network is a cellular network, and the second network is a WLAN.

[0052] In the above embodiment, the method disclosed herein can be applied to switching between WLAN and cellular networks, and is used by network equipment to decide whether the terminal is switched to WLAN or cellular network to ensure that the network where the terminal resides can enable the terminal's communication services (such as VoWiFi services, VoLTE services, VoNR services) to be executed smoothly and ensure communication quality.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, receiving the first measurement data and / or the second measurement data reported by the terminal includes:

[0054] Receive the first measurement data and / or second measurement data reported by the terminal based on a first event; the first event includes a first reporting requirement corresponding to at least one first parameter item, and the at least one first parameter item includes one or more parameter items in the first network and / or one or more parameter items in the second network; the first event is used to indicate: when the measurement data of the first parameter item meets the first reporting requirement corresponding to the first parameter item, the terminal actively reports the measurement data of the first parameter item.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, receiving the first measurement data and / or the second measurement data reported by the terminal includes:

[0056] sending a second event to the terminal, where the second event includes a second reporting requirement corresponding to at least one second parameter item, where the at least one second parameter item includes one or more parameter items in the first network and / or one or more parameter items in the second network; the second event is used to indicate that when the measurement data of the second parameter item meets the second reporting requirement corresponding to the second parameter item, the terminal reports the measurement data of the second parameter item;

[0057] receiving the first measurement data and / or second measurement data reported by the terminal based on the second event.

[0058] In the above embodiment, the terminal can actively report at least one of the first measurement data and the second measurement data to the network device, and / or the terminal can also report at least one of the first measurement data and the second measurement data to the network device based on an event (such as the second event) sent by the network device, thereby increasing the number of optional ways for the terminal to report the first measurement data and / or the second measurement data, and providing higher flexibility.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target network based on the first measurement data and / or the second measurement data includes:

[0060] determining whether the first measurement data and / or the second measurement data are all data required to determine a target network;

[0061] If the first measurement data and / or the second measurement data is less than all data required for determining the target network, a third event is sent to the terminal, where the third event is used to obtain third measurement data, where the third measurement data is data other than the first measurement data and / or the second measurement data in all data required for determining the target network; the third event includes a third reporting requirement corresponding to at least one third parameter item, where the third parameter item is a parameter item corresponding to the third measurement data, and the third event is used to indicate that when the measurement data of the third parameter item meets the third reporting requirement corresponding to the third parameter item, the terminal reports the measurement data of the third parameter item;

[0062] receiving third measurement data reported by the terminal based on the third event;

[0063] A target network is determined based on at least one of the first measurement data, the second measurement data, and the third measurement data.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target network based on the first measurement data and / or the second measurement data includes:

[0065] determining whether the first measurement data and / or the second measurement data are all data required to determine a target network;

[0066] The first measurement data and / or the second measurement data are all data required for determining the target network, and the target network is determined directly based on the first measurement data and / or the second measurement data.

[0067] In the above embodiment, a method is provided for a network device to determine the target network to which the terminal is to connect, so that the network device can successfully determine the target network, thereby enabling the network device to decide whether to trigger the terminal to switch to different networks for implementing different types of voice services (such as the network device decides whether to trigger the terminal to switch to a WLAN or a cellular network), thereby improving the flexibility of network switching and ensuring communication quality.

[0068] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target network based on the first measurement data and / or the second measurement data includes:

[0069] determining a load condition of the first network and a load condition of the second network;

[0070] A target network is determined based on at least one of the first measurement data, the second measurement data, a load condition of the first network, and a load condition of the second network.

[0071] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target network based on at least one of the first measurement data, the second measurement data, the load status of the first network, and the load status of the second network includes:

[0072] estimating a network with the best quality between the first network and the second network based on the first measurement data and / or the second measurement data;

[0073] The estimated load condition of the network is less than a first threshold, and determining whether the first measurement data and / or the second measurement data are all data required to determine the target network;

[0074] If the first measurement data and / or the second measurement data is less than all data required for determining the target network, a third event is sent to the terminal, where the third event is used to obtain third measurement data, where the third measurement data is data other than the first measurement data and / or the second measurement data in all data required for determining the target network; the third event includes a third reporting requirement corresponding to at least one third parameter item, where the third parameter item is a parameter item corresponding to the third measurement data, and the third event is used to indicate that when the measurement data of the third parameter item meets the third reporting requirement corresponding to the third parameter item, the terminal reports the measurement data of the third parameter item;

[0075] receiving third measurement data reported by the terminal based on the third event;

[0076] updating and determining a load condition of the first network and a load condition of the second network;

[0077] The target network is determined based on at least one of the first measurement data, the second measurement data, the third measurement data, an updated load condition of the first network, and an updated load condition of the second network.

[0078] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target network based on at least one of the first measurement data, the second measurement data, the load status of the first network, and the load status of the second network includes:

[0079] estimating a network with the best quality between the first network and the second network based on the first measurement data and / or the second measurement data;

[0080] The estimated load condition of the network is less than a first threshold, and determining whether the first measurement data and / or the second measurement data are all data required to determine the target network;

[0081] The first measurement data and / or the second measurement data are all data required to determine the target network, and the target network is determined directly based on at least one of the first measurement data, the second measurement data, the load condition of the first network, and the load condition of the second network.

[0082] In the above embodiment, when the network device decides whether to trigger the terminal to switch to different networks for implementing different types of voice services (such as the network device decides whether to trigger the terminal to switch to WLAN or cellular network), it will also refer to the load status of the first network and / or the second network, thereby greatly improving the accuracy of the network device's decision and ensuring communication quality.

[0083] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0084] estimating a network with the best quality between the first network and the second network based on the first measurement data and / or the second measurement data;

[0085] The estimated load condition of the network is greater than or equal to a first threshold, and a fourth event is sent to the terminal, the fourth event including a fourth reporting requirement corresponding to at least one fourth parameter item, the fourth parameter item being a parameter item corresponding to the measurement data required to determine the target network, and the fourth event being used to indicate: when the measurement data of the fourth parameter item meets the fourth reporting requirement corresponding to the fourth parameter item, the terminal reports the measurement data of the fourth parameter item; wherein the fourth reporting requirement is a reporting requirement that the measurement data of the terminal will not meet, and the fourth reporting requirement is used to limit the terminal from reporting measurement data.

[0086] In the above embodiment, when the load condition of the network with the best quality, estimated by the network device based on the first measurement data and / or the second measurement data, from the first network and the second network is greater than or equal to a first threshold, the network device may restrict the terminal from reporting measurement data by issuing a fourth event to the terminal. Since the network with the best quality estimated by the network device from the first network and the second network is likely to be the target network ultimately determined by the network device, i.e., likely the network to be subsequently accessed by the terminal, if the load condition of the estimated network with the best quality is greater than or equal to the first threshold, it indicates that the estimated network with the best quality is overloaded and may no longer be able to support communication connections with additional devices. Therefore, the network device may issue the fourth event to the terminal to restrict the terminal from reporting measurement data (i.e., prevent the terminal from reporting measurement data). As a result, the network device will not receive the measurement data reported by the terminal, and thus the network device will not be able to subsequently decide whether to trigger the terminal to switch networks based on the measurement data reported by the terminal. This avoids the situation where the terminal may subsequently switch to an overloaded network, thereby preventing network congestion.

[0087] In conjunction with some embodiments of the first aspect, in some embodiments, determining the target network includes:

[0088] At least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is greater than the communication quality of the second network, and / or the load condition of the first network is less than a first threshold, and the first network is determined as the target network;

[0089] At least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is lower than the communication quality of the second network, and / or the load condition of the second network is lower than a first threshold, and the second network is determined as the target network;

[0090] At least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is equal to the communication quality of the second network, and / or the load conditions of the first network and the second network are less than a first threshold, and the first network or the second network is determined as the target network.

[0091] In the above embodiment, a method is provided for a network device to determine a target network based on at least one of the first measurement data, the second measurement data, the third measurement data, the load condition of the first network, and the load condition of the second network, so that the network device can successfully determine the target network so that the network device can subsequently instruct the terminal to connect to the target network, thereby achieving the purpose of triggering the terminal to switch networks by decision by the network device.

[0092] In conjunction with some embodiments of the first aspect, in some embodiments, the target network is the same as the current access network of the terminal, and the first indication is used to indicate residing in the target network;

[0093] The target network is different from the current access network of the terminal, and the first information is used to indicate at least one of the following:

[0094] Switching from the current access network to the target network;

[0095] To register the current access network;

[0096] Re-register to the target network.

[0097] In combination with some embodiments of the first aspect, in some embodiments, the first information is also used to indicate: when the terminal fails to switch and / or register the target network, second information is sent to the network device, and the second information is used to indicate that the terminal fails to switch and / or register the target network.

[0098] In the above embodiment, the first information sent by the network device may further instruct the terminal on how to connect to the target network, so that the terminal can successfully connect to the target network based on the first instruction information. Furthermore, the first information may further instruct the terminal to send second information to the network device when the terminal fails to switch to and / or register with the target network, thereby notifying the network device of the failure. The network device can then promptly perform remedial actions to ensure that the terminal can successfully connect to the target network and guarantee communication quality.

[0099] In a second aspect, an embodiment of the present disclosure provides a communication method, which is performed by a terminal, and the method includes at least one of the following:

[0100] The terminal reports first measurement data and / or second measurement data to the network device; wherein the first measurement data is measurement data corresponding to the first network, and the second measurement data is measurement data corresponding to the second network; the first network and the second network can be used to implement different types of voice services respectively;

[0101] The terminal receives first information sent by the network device, where the first information is used to indicate a target network, where the target network is the first network or the second network, and the target network is a network determined by the network device to be connected to by the terminal;

[0102] The terminal connects to the target network based on the first information.

[0103] In the above embodiment, the terminal can report first measurement data and / or second measurement data to the network device, so that the network device can determine a target network from the first network and the second network based on the first measurement data and / or the second measurement data reported by the terminal, and indicate the target network to the terminal so that the terminal can connect to the target network. The first network and the second network can each be used to implement different types of voice services. Therefore, it can be seen that in the embodiments of the present disclosure, the network device can decide whether to trigger the terminal to switch to different networks for implementing different types of voice services (e.g., the network device decides whether to trigger the terminal to switch to a WLAN or a cellular network). Compared to the related art, in which only the terminal can decide whether to switch to a WLAN or a cellular network, the present disclosure provides a new method for deciding whether to switch to a WLAN or a cellular network, thereby improving the flexibility of switching between WLAN and cellular networks. Furthermore, in the present disclosure, when the network device is used to decide whether to trigger a switch between a WLAN and a cellular network, because the network device has higher capabilities (such as software and hardware capabilities, computing power, etc.) than the terminal, the decision made by the network device is more accurate, thereby ensuring handover accuracy, avoiding unnecessary handovers, and improving communication quality.

The technical features in different embodiments can be combined to form a new embodiment based on their inherent logical relationships.

[0193] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0194] In the embodiments of the present disclosure, unless otherwise specified, elements expressed in the singular, such as "a", "an", "the", "above", "said", "the", "the", etc., may mean "one and only one", or "one or more", "at least one", etc. For example, when using articles such as "a", "an", "the" in English in translation, the noun following the article may be understood as a singular expression or a plural expression.

For the statement of the description object, please refer to the description in the context of the claims or embodiments, and no unnecessary restriction should be constituted due to the use of prefixes. For example, if the description object is a "field", the ordinal number before the "field" in the "first field" and the "second field" does not limit the position or order between the "fields". "First" and "second" do not limit whether the "fields" they modify are in the same message, nor do they limit the order of the "first field" and the "second field". For another example, if the description object is a "level", the ordinal number before the "level" in the "first level" and the "second level" does not limit the priority between the "levels". For another example, the number of description objects is not limited by the ordinal number and can be one or more. Taking "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes can be the same or different. For example, if the description object is "device", then the "first device" and the "second device" can be the same device or different devices, and their types can be the same or different; for another example, if the description object is "information", then the "first information" and the "second information" can be the same information or different information, and their contents can be the same or different.

[0207] In some embodiments, the access network device, the core network device, or the network device can be replaced by a terminal. For example, the various embodiments of the present disclosure can also be applied to a structure in which the communication between the access network device, the core network device, or the network device and the terminal is replaced by communication between multiple terminals (for example, it can also be called device-to-device (D2D), vehicle-to-everything (V2X), etc.). In this case, it can also be set as a structure in which the terminal has all or part of the functions of the access network device. In addition, language such as "uplink" and "downlink" can also be replaced by language corresponding to communication between terminals (for example, "side"). For example, uplink channels, downlink channels, etc. can be replaced by side channels, and uplinks, downlinks, etc. can be replaced by side links.

For another example, appropriate deformation adjustments can be made based on the above tables, such as splitting, merging, etc. The names of the parameters shown in the titles of the above tables may also adopt other names that can be understood by the communication device, and the values ​​or representations of the parameters may also adopt other values ​​or representations that can be understood by the communication device. When implementing the above tables, other data structures may also be used, such as arrays, queues, containers, stacks, linear lists, pointers, linked lists, trees, graphs, structures, classes, heaps, hash tables or hash tables, etc.

[0214] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure. As shown in Figure 1, the communication system 100 may include at least one of a network device 101 and a terminal 102. The network device 101 may include at least one of an access network device and a core network device.

[0217] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0218] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0219] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element. Exemplarily, the location management function network element includes a location server (location server), which may be implemented as any one of the following: Location Management Function (LMF), Enhanced Serving Mobile Location Centre (E-SMLC), Secure User Plane Location (SUPL), and Secure User Plane Location Platform (SUPLLP).

[0220] 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. Ordinary technicians in this field 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.

[0221] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0222] The embodiments of the present disclosure can 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), 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) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0223] Optionally, due to certain needs, the terminal usually needs to switch between WLAN and cellular network. For example, when the terminal is connected to WLAN, if the WLAN signal is poor and affects the VoWiFi service, the terminal needs to switch from WLAN to the cellular network. Alternatively, when the terminal is connected to the cellular network, if the terminal moves to an environment with only WLAN signal, the terminal needs to switch from the cellular network to WLAN. In the related art, it is the terminal that decides whether to trigger the switch between WLAN and cellular network, and there is no method for other devices to decide whether to trigger the switch between WLAN and cellular network, which has low flexibility. In addition, due to the limitation of the terminal's capabilities, its switching decision may be inaccurate. It may happen that the current communication situation does not require switching between WLAN and cellular network, but the terminal decides to trigger the switch between WLAN and cellular network, resulting in unnecessary switching and affecting the communication quality.

[0224] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0225] Step 2101: The terminal actively reports first measurement data and / or second measurement data.

[0226] Optionally, the terminal may actively report the first measurement data and / or the second measurement data to the network device, and the network device may receive the first measurement data and / or the second measurement data.

[0227] Optionally, the first measurement data may be measurement data corresponding to the first network, for example, measurement data of a channel in the first network; and the second measurement data may be measurement data corresponding to the second network, for example, measurement data of a channel in the second network. The first network and the second network may be respectively used to implement different types of voice services. Optionally, the first network may be the network currently accessed by the terminal, or the second network may be the network currently accessed by the terminal. Optionally, the first network may be a WLAN, and the second network may be a cellular network; or the first network may be a cellular network, and the second network may be a WLAN. The WLAN network may be used to implement VoWiFi services, and the corresponding measurement data in the WLAN may be measurement data corresponding to Wi-Fi services, for example, measurement data of Wi-Fi service channels. The cellular network may be used to implement VoNR and VoLTE services, and the corresponding measurement data in the cellular network may be channel measurement data in a third-generation partnership project (3GPP) heterogeneous or homogeneous neighboring cell. Optionally, the aforementioned "heterogeneous technology" may be understood, for example, as different communication technologies, and the aforementioned "same technology" may be understood as the same communication technology. Optionally, the communication technology may be, for example, second generation mobile communication technology (2G), third generation mobile communication technology (3G), fourth generation mobile communication technology (4G), 5G, and future evolved communication technology (such as sixth generation mobile communication technology (6G), seventh generation mobile communication technology (7G)). Assuming that the current serving cell is a 2G cell, the neighboring cell with the same technology may be a 2G cell, and the neighboring cell with a different technology may be a non-2G cell, such as a 3G cell, a 4G cell, a 5G cell, etc.

[0228] Optionally, the terminal may report the first measurement data and / or the second measurement data based on a first event. Optionally, the first event may include a first reporting requirement corresponding to at least one first parameter item, and the at least one first parameter item may include one or more parameter items in the first network and / or one or more parameter items in the second network. The first event may be used to indicate that when the measurement data of the first parameter item meets the first reporting requirement corresponding to the first parameter item, the terminal actively reports the measurement data of the first parameter item. Optionally, each first parameter item corresponds to a first reporting requirement, and the first reporting requirement may be, for example, a first measurement threshold. When the measurement data of the parameter item in the first network reaches or is less than the corresponding first measurement threshold, the terminal may report the measurement data of the parameter item in the first network (i.e., the aforementioned first measurement data) to the network device; when the measurement data of the parameter item in the second network reaches or is less than the corresponding second measurement threshold, the terminal may report the measurement data of the parameter item in the second network (i.e., the aforementioned second measurement data) to the network device.

[0229] Optionally, taking the first network as a WLAN and the second network as a cellular network as an example, the one or more parameter items in the WLAN may include at least one of the following: a Medium Access Control (MAC) address, an Internet Protocol (IP) address, a Service Set Identifier (SSID), a frequency, a channel quality, a Received Signal Strength Indication (RSSI), and a channel interference. The one or more parameter items in the cellular network may include at least one of the following: a bandwidth (band), a frequency (Freq), a Physical Cell ID (PCI), a Reference Signal Received Power (RSRP), a Reference Signal Received Quality (RSRQ), and a Signal to Interference plus Noise Ratio (SNR).

[0230] For example, assuming that the first reporting requirement corresponding to the parameter item "RSRP" in the cellular network in the first event is: reaching the measurement threshold A, the terminal will measure the RSRP in the cellular network in real time. When the measured RSRP in the cellular network is B, and B is greater than A, it is confirmed that the measurement data of the RSRP in the cellular network reaches the measurement threshold A, and it is determined that the corresponding first reporting requirement is met. At this time, the terminal can report the measurement data of the RSRP in the cellular network to the network device: B.

[0231] Optionally, the first event may be determined by the terminal based on a protocol agreement, or may be pre-configured to the terminal by a network device.

[0232] Optionally, the above-mentioned first measurement data can be used to reflect the communication quality of the first network, and the above-mentioned second measurement data can be used to reflect the communication quality of the second network. Optionally, when the terminal reports the first measurement data and / or the second measurement data based on the first event, it can be when the communication quality of the first network meets certain conditions (such as good or poor communication quality), the terminal reports the first measurement data, and / or, when the communication quality of the second network meets certain conditions (such as good or poor communication quality), the terminal reports the second measurement data, so that the network device can subsequently determine which network has better communication quality based on the first measurement data and the second measurement data, and then instruct the terminal to switch to the network with better communication quality. Optionally, the first event can be named "Q event" for example, or it can be named other events, and this disclosure is not limited to this.

[0233] It should be noted that the parameter items mentioned above are only examples of descriptions of this disclosure. It should be understood that networks (such as WLAN and cellular networks) are not limited to the parameter items in the above examples, and other parameter items may also exist. Among them, the parameter items in the events mentioned in this disclosure (such as the first event mentioned above, and the subsequent second event, third event, and fourth event) may also be parameter items not covered by the above examples, and this disclosure does not specifically limit this.

[0234] Step 2102: If the first measurement data and / or the second measurement data is less than all the data required to determine the target network, a third event is sent to the terminal.

[0235] Optionally, the target network may be a network to which the terminal is to connect, as determined by the network device. The target network may be the first network or the second network. For example, the target network may be the network with better communication quality among the first network or the second network. Optionally, the network device may first determine whether the first measurement data and / or the second measurement data are all the data required to determine the target network. When the first measurement data and / or the second measurement data are less than all the data required to determine the target network, the network device may send a third event to the terminal. Optionally, the third event is used to obtain third measurement data. The third measurement data is: data other than the first measurement data and / or the second measurement data in all the data required to determine the target network. The third event may include a third reporting requirement corresponding to at least one third parameter item, the third parameter item being a parameter item corresponding to the third measurement data. The third event is used to indicate that when the measurement data of the third parameter item meets the third reporting requirement corresponding to the third parameter item, the terminal reports the measurement data of the third parameter item. Optionally, each third parameter item corresponds to a third reporting requirement, which may be a third measurement threshold. When the measurement data of the third parameter item reaches or is less than the third measurement threshold, the third reporting requirement is considered to be met.

[0236] For example, assuming that the target network is determined from the WLAN network and the cellular network, the channel quality and RSSI in the WLAN network, as well as the RSRP and RSRQ in the cellular network, need to be referenced. However, in step 2101, the terminal only reports the channel quality in the WLAN network and the RSRP in the cellular network. In this case, the third parameter items included in the third event sent by the network device to the terminal may be: the RSSI in the WLAN network and the RSRQ in the cellular network. The third reporting requirement of the third event may, for example, be: the measured RSSI data in the WLAN network is less than threshold 1, and / or the measured RSRQ data in the 3GPP inter-technology neighboring cell in the cellular network is greater than threshold 2; or the third reporting requirement of the third event may, for example, be: the measured RSRQ data in the 3GPP inter-technology neighboring cell in the cellular network is less than threshold 1, and / or the measured RSSI data in the WLAN network is greater than threshold 2.

[0237] Optionally, the third event may be named, for example, a "P event," a "query event," or other events, which is not limited in the present disclosure.

[0238] Step 2103: The terminal reports third measurement data to the network device based on the third event.

[0239] For example, assuming that the third parameter item included in the third event sent by the network device to the terminal may be: RSSI in the WLAN network and RSRQ in the cellular network, and the third reporting requirement of the third event is: measurement data of the RSSI in the WLAN network is less than threshold 1, and / or measurement data of the RSRQ in a 3GPP inter-technology neighboring cell is greater than threshold 2. The terminal may then measure the RSSI in the WLAN network and the RSRQ in the cellular network in real time based on the third event. When the RSSI in the WLAN network and the RSRQ in the cellular network respectively meet the corresponding third reporting requirements, i.e., when the measurement data of the RSSI in the WLAN network is less than threshold 1 and / or the measurement data of the RSRQ in a 3GPP inter-technology neighboring cell is greater than threshold 2, the terminal will report the measurement data corresponding to the RSSI in the WLAN network and the RSRQ in the cellular network (i.e., the aforementioned third measurement data) to the network device.

[0240] Step 2104: The network device determines a target network based on at least one of the first measurement data, the second measurement data, and the third measurement data.

[0241] Optionally, in some embodiments, when at least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is greater than the communication quality of the second network, the first network is determined as the target network; when at least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is less than the communication quality of the second network, the second network is determined as the target network; when at least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is equal to the communication quality of the second network, the first network or the second network is determined as the target network.

[0242] Step 2105: The network device sends first information to the terminal, where the first information can be used to indicate a target network.

[0243] Optionally, in some embodiments, when the target network is the same as the current access network of the terminal, the first indication can be used to indicate residing in the target network; when the target network is different from the current access network of the terminal, the first information can be used to indicate at least one of the following: switching from the current access network to the target network, deregistering the current access network, and reregistering to the target network.

[0244] In other embodiments, the first information may also be used to instruct: when the terminal fails to switch to and / or register with the target network, to send second information to the network device, where the second information is used to indicate the failure of the terminal to switch to and / or register with the target network. The first information instructs the terminal to send the second information to the network device, so that the terminal can promptly notify the network device of the failure to switch to and / or register with the target network. The network device can then perform corresponding remedial actions to ensure that the terminal can successfully connect to the target network and guarantee communication quality.

[0245] Optionally, the first information may be at least one of the following: an Over The Air (OTA) message, an Internet Key Exchange Protocol (IKE) message, or a Session Initiation Protocol (SIP) message.

[0246] Step 2106: The terminal connects to the target network based on the first information.

[0247] Optionally, when the first information indicates that the terminal is resident on the target network, the target network is the terminal's current access network. In this case, the terminal does not need to switch networks and can continue to reside in the current access network. When the first information instructs the terminal to switch from the current access network to the target network, the terminal can perform a network switching process to switch from the current access network to the target network. When the first information instructs the terminal to deregister the current access network and reregister with the target network, the terminal can deregister the current access network and reregister with the target network.

[0248] Optionally, when the first information also indicates that: when the terminal fails to switch and / or register the target network, a second information is sent to the network device. If the terminal fails to switch or register the target network based on the first information, the terminal can also send the second information to the network device to promptly notify the network device that the terminal fails to switch and / or register the target network. The network device can then perform corresponding remedial operations to ensure that the terminal can successfully connect to the target network and ensure communication quality.

[0249] It should be noted that when the target network is a cellular network, the terminal can access the cellular network based on 3GPP access technology. When the target network is a WLAN network, the terminal can access the WLAN network based on non-3GPP (Non-3GPP) access technology.

[0250] It should also be noted that in some embodiments, when the target network determined by the network device in the above step 2104 is the current access network of the terminal, it is not necessary to execute the above steps 2105 and 2106, that is: the network device does not instruct the terminal, and at this time, the terminal will continue to reside in the current access network as usual.

[0251] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2106. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, and steps S2101+S2102 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0252] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0253] FIG2B is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0254] Step 2201: The terminal actively reports first measurement data and / or second measurement data.

[0255] Step 2202: The network device determines a target network based on at least one of the first measurement data and the second measurement data.

[0256] Optionally, in some embodiments, when the first measurement data and / or the second measurement data are all the data required to determine the target network, the network device may directly determine the target network based on the first measurement data and / or the second measurement data actively reported by the terminal.

[0257] Step 2203: Send first information to the terminal, where the first information can be used to indicate a target network.

[0258] Step 2204: The terminal connects to the target network based on the first information.

[0259] For a detailed description of steps 2201 - 2204 , please refer to the above embodiment description.

[0260] It should also be noted that in some embodiments, when the target network determined by the network device in the above step 2202 is the current access network of the terminal, it is not necessary to execute the above steps 2203 and 2204, that is: the network device does not instruct the terminal, then the terminal will continue to reside in the current access network as usual.

[0261] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2204. For example, step S2201 may be implemented as an independent embodiment, step S2202 may be implemented as an independent embodiment, step S2203 may be implemented as an independent embodiment, and steps S2201+S2202 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0262] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0263] FIG2C is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2C , the embodiment of the present disclosure relates to a communication method for use in a communication system 100, the method comprising:

[0264] Step 2301: The network device sends a second event to the terminal.

[0265] Optionally, the second event may include a second reporting requirement corresponding to at least one second parameter item, and the at least one second parameter item may include one or more parameter items in the first network and / or one or more parameter items in the second network. The second event may be used to indicate that when the measurement data of the second parameter item meets the second reporting requirement corresponding to the second parameter item, the terminal reports the measurement data of the second parameter item (i.e., the aforementioned first measurement data and / or second measurement data). For a detailed introduction to the parameter items and reporting requirements, please refer to the above-mentioned introduction to the first event, third event, first measurement data, and second measurement data.

[0266] Optionally, the second event may include at least one of the following events: an A event, a B event, a C event, a W event, a V event, and an H event. The A event, the B event, and the C event may be used to enable the terminal to report corresponding measurement data in a cellular network, and the W event, the V event, and the H event may be used to enable the terminal to report corresponding measurement data in a WLAN network.

[0267] Step 2302: The terminal reports the first measurement data and / or the second measurement data to the network device based on the second event.

[0268] Step 2303: The network device determines the load status of the first network and the load status of the second network.

[0269] Optionally, the network device may determine the server status of the first network and determine the load status of the first network based on the server status of the first network, or the network device may determine the server status of the second network and determine the load status of the second network based on the server status of the second network.

[0270] Step 2304: The network device estimates the network with the best quality between the first network and the second network based on the first measurement data and / or the second measurement data.

[0271] Optionally, as can be seen from the above content, the first measurement data is used to reflect the communication quality of the first network, and the second measurement data is used to reflect the communication quality of the second network. The network device can roughly estimate the communication quality of the first network and the communication quality of the second network based on the first measurement data and the second measurement data, and then can estimate the network with the best quality between the first network and the second network.

[0272] Step 2305: The network device determines whether the estimated network load condition is less than a first threshold value. When the estimated network load condition is less than the first threshold value, step 2306 is executed. When the estimated network load condition is greater than or equal to the first threshold value, subsequent step 2314 can be executed.

[0273] Optionally, the network estimated here is likely to be the target network determined by the subsequent network device, that is, it may be the network that the subsequent terminal wants to access. Therefore, the network device can predetermine the size of the estimated network load condition to determine whether it supports the subsequent access of the terminal. When the estimated network load condition is less than a first threshold, it means that the estimated network load condition is small and it may support the subsequent access of the terminal. At this time, the subsequent step 2306 can be executed. When the estimated network load condition is greater than or equal to the first threshold, it means that the estimated network load condition is large and it may not support the subsequent access of the terminal. At this time, the subsequent step 2314 can be executed.

[0274] Step 2306: The estimated network load condition is less than the first threshold value. The network device determines whether the first measurement data and / or the second measurement data are all the data required to determine the target network. When the first measurement data and / or the second measurement data are not all the data required to determine the target network, execute steps 2307-2310, 2312, and 2313. When the first measurement data and / or the second measurement data are all the data required to determine the target network, execute steps 2311-2313.

[0275] Step 2307: The first measurement data and / or the second measurement data is less than all the data required to determine the target network, and the network device sends a third event to the terminal.

[0276] For a detailed description of the third event, please refer to the above embodiment description.

[0277] In addition, it should be noted that in some embodiments, the network device may also send a third event based on the estimated network. Optionally, when the estimated network load condition is less than the first threshold, the third reporting requirement in the third event sent by the network device to the terminal may be a requirement that tends to determine the estimated network as the target network. For example, assuming that the network estimated by the network device in the above step 2304 is a cellular network, and the load condition of the cellular network is less than the first threshold, at this time, if the network device uses the method of the above embodiment to determine that the third parameter item in the third event is: RSSI in the WLAN network and RSRQ in the cellular network, then the third reporting requirement may be: a requirement that is biased towards determining the cellular network as the target network. For example, the third reporting requirement may be: the measurement data of RSSI in the WLAN network is less than threshold 1, and / or, the measurement data of RSRQ in the 3GPP heterogeneous technology neighboring cell in the cellular network is greater than threshold 2. Therefore, when the measurement data of the terminal meets the third reporting requirement, it means that the communication quality of the current cellular network is good, and / or the communication quality of the WLAN network is poor. At this time, the network device will tend to determine the cellular network as the target network.

[0278] Step 2308: The terminal reports third measurement data to the network device based on the third event.

[0279] For other detailed descriptions of steps 2307-2308, please refer to the above embodiment description.

[0280] Step 2309: The network device updates and determines the load status of the first network and the load status of the second network.

[0281] Step 2310: The network device determines a target network based on at least one of the first measurement data, the second measurement data, the third measurement data, the updated load condition of the first network, and the updated load condition of the second network.

[0282] Optionally, when the load condition of the first network (i.e., the load condition of the first network updated and determined in step 2310) is less than a first threshold, and / or at least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is greater than the communication quality of the second network, the first network is determined as the target network; when the load condition of the second network (i.e., the load condition of the second network updated and determined in step 2310) is less than the first threshold, and / or at least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is less than the communication quality of the second network, the second network is determined as the target network; when the load conditions of the first network and the second network are less than the first threshold, and / or at least one of the first measurement data, the second measurement data, and the third measurement data indicates that the communication quality of the first network is equal to the communication quality of the second network, the first network or the second network is determined as the target network.

[0283] Step 2311: The first measurement data and / or the second measurement data are all the data required to determine the target network. The network device directly determines the target network based on at least one of the first measurement data, the second measurement data, the load status of the first network, and the load status of the second network.

[0284] For a detailed description of step 2311 , please refer to the above embodiment description.

[0285] Step 2312: The network device sends first information to the terminal, where the first information can be used to indicate a target network.

[0286] Step 2313: The terminal connects to the target network based on the first information.

[0287] For a detailed description of steps 2312 - 2313 , please refer to the above embodiment description.

[0288] Step 2314: If the estimated network load condition is greater than or equal to the first threshold, the network device sends a fourth event to the terminal.

[0289] Optionally, the fourth event may include a fourth reporting requirement corresponding to at least one fourth parameter item, and the fourth parameter item may be a parameter item corresponding to the measurement data required to determine the target network. The fourth event is used to indicate: when the measurement data of the fourth parameter item meets the fourth reporting requirement corresponding to the fourth parameter item, the terminal reports the measurement data of the fourth parameter item; wherein the fourth reporting requirement is a reporting requirement that the measurement data of the terminal will not meet, and the fourth reporting requirement is used to limit the terminal from reporting measurement data, that is, since the fourth reporting requirement is a reporting requirement that the measurement data of the terminal will not meet, the measurement data of the terminal will not meet the fourth reporting requirement at all, which makes it impossible for the terminal to report the measurement data required to determine the target network to the network device.

[0290] Optionally, as can be seen from the foregoing content, the network estimated here is most likely to be the target network determined by the subsequent network device, that is, it may be the network that the subsequent terminal is to access. Therefore, when the load condition of the estimated network is greater than or equal to the first threshold, it means that the load condition of the estimated network is large, and it may not support the subsequent access of the terminal. Based on this, the network device makes the fourth reporting requirement in the fourth event sent to the terminal a reporting requirement that the terminal's measurement data will not meet, so that the terminal will not report the measurement data of the fourth parameter item (that is, the measurement data required to determine the target network) to the network device, thereby making it impossible for the network device to determine the target network, and thus the terminal will not switch to the above-mentioned estimated network with a larger load, thereby avoiding network congestion.

[0291] It should be noted that step 2314 is performed when the first measurement data and / or second measurement data acquired by the network device in step 2302 is less than all the data required to determine the target network. Optionally, when the first measurement data and / or second measurement data acquired by the network device in step 2302 is all the data required to determine the target network, and the network load condition estimated in step 2305 is greater than or equal to the first threshold, the network device stops the process and does not determine the target network.

[0292] It should also be noted that in the embodiment of Figure 2C, after executing the above steps 2301-2302, 2102-2106 in the embodiment of Figure 2A can also be executed, or 2102-2104 in the embodiment of Figure 2B can also be executed, and this disclosure does not make specific limitations.

For example, step S5101 may be implemented as an independent embodiment, and step S5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0439] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0440] The following is an exemplary introduction to the above method.

[0441] Currently, there is no network-side solution for controlling the switching between Wi-Fi and cellular services. Firstly, VoWiFi is defined as a supplementary voice service to VoLTE / VoNR, but the cost of full-scale network investment is prohibitive, with a significant disparity between investment and benefits. Secondly, most Wi-Fi access points are not controlled by operators, making unified management and control impossible.

[0442] Currently, terminals rely primarily on chip manufacturers for implementation, with the terminal making a unified judgment based on Wi-Fi / Cellular signal quality to trigger Handover. This disclosure provides a network-side solution for controlling Wi-Fi and Cellular handover. This disclosure applies to scenarios where the network and device support this protocol and support interaction with the solution:

[0443] 1. The terminal actively reports the Wi-Fi / Cellular service status;

[0444] 2. The network sends a query to the current WIFI / Cellular service status of the network;

[0445] 3. The current terminal detects that the Wi-Fi or Cellular service status is better and requires network support for switching;

[0446] 4. The current network end decides the terminal priority behavior based on the terminal reported data and the current network server load and status.

[0447] Optional instances:

[0448] 1. This solution provides a way for the network to centrally control the terminal network selection mechanism;

[0449] 2. The network supports issuing instructions such as switching / re-registration / de-registration / blocking mechanisms through OTA, IKE messages, or SIP messages, and the terminal can execute them according to the instructions;

[0450] 3. The terminal can execute relevant policies, perform regular scanning and reporting, or report based on optimization strategies, and perform VoNR / VoWiFi / VoNR switching / re-registration / de-registration / blocking mechanisms based on network decisions;

[0451] 4. The network issues targeted P events based on the current terminal reporting status and the current network load or network status. Based on the measurement results, the terminal is required to execute relevant commands, thereby achieving the purpose of controlling the terminal's priority residence.

[0452] Optionally, Figure 5B is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. The method shown in Figure 5B corresponds to a mechanism in which the terminal actively reports an event. Optionally, as shown in Figure 5B, the terminal can perform a Q1 event (i.e., the aforementioned first event) to report the cellular cell (i.e., the aforementioned cellular network) or WIFI (i.e., the aforementioned WLAN network) measurement information (i.e., the aforementioned first measurement data and / or second measurement data). Afterwards, the network device can perform processing based on the Q1 information (i.e., the aforementioned determination of whether the first measurement data and / or the second measurement data are all the data required to determine the target network). When the network device determines that it needs to further obtain other parameters (i.e., when the first measurement data and / or the second measurement data are less than all the data required to determine the target network), the network device will send an event query (i.e., the aforementioned third event) to the terminal. The terminal determines based on the event query sent by the network device that it will report when the event threshold (i.e., the third reporting requirement) is met. When the network device determines that no further parameters need to be obtained (i.e., the current information has been processed, or as previously mentioned: the first measurement data and / or the second measurement data are all the data required to determine the target network), the network device does not need to send an event query to the terminal. The network device can then make a further decision based on the collected information to determine whether the terminal should reside on VoWiFi (i.e., reside on the WLAN network) or VoLTE / VoNR (i.e., reside on the cellular network). The network device can then issue instructions via OTA messages, IKE messages, or SIP messages to instruct the terminal to switch / reregister / deregister, and can carry a blocking mechanism (i.e., as previously mentioned: when the terminal fails to switch and / or register with the target network, second information is sent to the network device, indicating that the terminal failed to switch and / or register with the target network). The terminal can then perform corresponding operations according to the instructions to complete the Radio Access Type (RAT) switching mechanism. Optionally, upon receiving an instruction to use a cellular circuit for wireless transmission, the terminal deactivates the Wi-Fi connection, and upon receiving an instruction to stop using the cellular circuit for wireless transmission, the terminal resumes the Wi-Fi connection.

[0453] Optionally, Figure 5C is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. The method shown in Figure 5C corresponds to an event and its mechanism sent by the network. Optionally, as shown in Figure 5C, the network device can send an A / B / C / W / V / H event (i.e., the aforementioned second event) to the terminal, and the terminal can perform measurements based on the event threshold sent by the network device (i.e., the aforementioned second reporting requirement). When the relevant threshold is reached, the terminal reports relevant data to the network device (i.e., the aforementioned terminal reports the first measurement data and / or the second measurement data to the network device based on the second event). The network device can make a judgment based on the acquired terminal data and the network status (i.e., the load condition of the aforementioned first network and / or the load condition of the second network) to decide whether the terminal (or UE) performs biased registration and sends a P1 event or a P2 event based on the bias. Among them, sending the P1 event or P2 event based on bias can be understood as the aforementioned: when the network load condition estimated by the network device is less than the first threshold, and the first measurement data and / or the second measurement data is less than all the data required to determine the target network, sending the third event; and when the network load condition estimated by the network device is greater than or equal to the first threshold, sending the fourth event to the terminal. Afterwards, the terminal performs measurements according to the event threshold issued by the network device (i.e., the aforementioned third reporting requirement and / or fourth reporting requirement) and reports the WIFI / cellular results, so that the network device decides based on the measurement results and network status whether the terminal needs to reside in VoWiFi (i.e., reside in the WLAN network) or reside in VoLTE / VoNR (i.e., reside in the cellular network), and can issue instructions through OTA messages, IKE messages, and SIP messages to instruct the terminal to switch / re-register / des-register, and can carry a block mechanism (i.e., the aforementioned: when the terminal fails to switch and / or register the target network, a second information is sent to the network device, and the second information is used to indicate that the terminal fails to switch and / or register the target network). After that, the terminal can perform corresponding operations according to the instructions to complete the radio access type (Radio Access Type, RAT) switching mechanism.

[0454] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.

Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits.

Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0456] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP).

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
