[0003] The present application belongs to the field of communication technology, and specifically relates to a network registration processing method, device, system and communication equipment. Background Art

The first option enables cross-network handover, where network-side equipment can switch user equipment (UE) services from one network to another. The second option does not support cross-network handover. In the first option, if a UE is attached or registered to two different networks (i.e., in dual-registration mode), and the UE has services on both networks, performing a network handover will cause service interruption.

[0140] Before describing the embodiments of the present application, the following briefly introduces the relevant technologies:

[0141] The network interworking architecture includes two options: one that supports the N26 interface and one that does not. The N26-supported option enables cross-network handover, with network-side equipment able to switch user equipment (UE) services from one network to another. The N26-unsupported option does not support network handover, with the UE autonomously moving services between the two networks (by spontaneously establishing a corresponding service connection in the other network).

[0142] In the solution supporting the N26 interface, taking the interworking architecture of the Evolved Packet System (EPS) and the 5G System (5GS) supporting the N26 interface as an example, if the UE is attached to the EPS and registered in the 5GS (i.e., the UE is in dual registration mode), when the UE has services in both networks, since the UE services are already being executed in the target network, or there is already an MME or AMF / SMF serving the UE, once the network-side device performs a network switching operation, the UE services will be interrupted. Alternatively, in order to prohibit network switching, the UE will be prohibited from reporting measurement reports, or, the UE will not be prohibited from reporting measurement reports but will be required to report erroneous measurement reports.

[0143] In view of this, an embodiment of the present application provides a network registration processing solution that enables the UE to exit the dual registration mode and enter the single registration mode when necessary, thereby avoiding UE service interruption caused by possible network switching, thereby ensuring that the system will not have abnormalities due to network switching.

[0144] The following, in conjunction with the accompanying drawings, describes in detail the network registration processing method, network registration processing device, and network registration processing system provided by the embodiments of the present application through some embodiments and their application scenarios.

[0145] FIG2 is a flowchart of a network registration processing method provided by an embodiment of the present application. As shown in FIG2 , the network registration processing method includes the following steps:

[0146] Step 201: When the terminal is in the first mode and a trigger condition is met, the terminal performs a first operation;

[0147] In the first mode, the terminal is associated with a first network, and the terminal is associated with a second network;

[0148] The terminal is associated with the first network, including any of the following:

[0149] The terminal is attached to the first network;

[0150] The terminal is registered with the first network;

[0151] The terminal is connected to the first network;

[0152] The terminal is associated with the second network, including any of the following:

[0153] The terminal is attached to the second network;

[0154] The terminal is registered with the second network;

[0155] The terminal is connected to the second network;

[0156] The first operation includes the terminal detaching from or deregistering from one of the first network and the second network.

[0157] In the embodiments of the present application, the relationship between a terminal and a network includes, but is not limited to, the terminal being attached to the network, the terminal being registered with the network, and the terminal being connected to the network. Different terms may be used to represent the relationship between the terminal and the network for different networks. For example, for a 4th Generation (4G) network, "attached to" is generally used, and for a 5th Generation (5G) network, "registered to" is generally used.

[0158] The first mode can be expressed as a dual-association mode, a dual-registration mode, a dual-attachment mode, or a dual-connection mode. Accordingly, the second mode mentioned below can be expressed as a single-association mode, a single-registration mode, a single-attachment mode, or a single-connection mode. For ease of description, in some examples, embodiments of the present application use "dual-registration mode" to represent the first mode and "single-registration mode" to represent the second mode.

[0159] The trigger condition can be understood as a mode switching condition (i.e., switching from a first mode to a second mode). When the terminal is in the first mode, it can determine whether the trigger condition is met to determine whether the terminal needs to switch from the first mode to the second mode. If the trigger condition is met, the terminal meets the conditions for mode switching. In this case, the terminal can implement the terminal mode switching by executing the first operation.

[0160] The terminal performing the first operation includes: the terminal detaching from or deregistering from one of the first network and the second network. If the terminal detaches from or deregisters from the first network, the terminal is disassociated from the first network, and the terminal is now associated only with the second network. If the terminal detaches from or deregisters from the second network, the terminal is disassociated from the second network, and the terminal is now associated only with the first network.

[0161] Correspondingly, if the trigger condition is not met, the terminal does not meet the conditions for mode switching. In this case, the terminal can continue to maintain the first mode.

[0162] It should be noted that whether the trigger condition is met is judged or determined by the terminal, and the parameters related to the trigger condition can be configured by the network side device, by the application layer of the terminal, or pre-defined through the protocol, or pre-written into the relevant configuration parameters of the terminal. The embodiments of the present application do not limit this.

[0163] In an embodiment of the present application, a terminal performs a first operation when in a first mode and a trigger condition is met; in the first mode, the terminal is associated with a first network and the terminal is associated with a second network; the first operation includes the terminal detaching from or deregistering from one of the first network and the second network. Through the above process, the terminal can perform the first operation to switch the terminal from the dual registration mode (i.e., the first mode) to the single registration mode (i.e., the second mode) when the trigger condition is met, so that the terminal can exit the dual registration mode when needed to avoid terminal service interruption due to possible network switching.

[0164] In the embodiment of the present application, the types of the first network and the second network are not limited. Optionally, the first network includes an EPS network (i.e., a 4G network) and the second network includes a 5GS network (i.e., a 5G network); or, the first network includes a 5GS network and the second network includes an EPS network.

[0165] In some embodiments, when the first operation includes the terminal detaching from or deregistering from the first network, the first operation further includes:

[0166] The terminal deletes the session of the terminal in the first network.

[0167] Here, the type of session varies depending on the type of the first network. For example, if the first network is a 4G network, the terminal may delete its packet data network (PDN) connection on the first network. If the first network is a 5G network, the terminal may delete its protocol data unit (PDU) session on the first network.

[0168] In some embodiments, when the first operation includes the terminal detaching from or deregistering from the second network, the first operation further includes:

[0169] The terminal deletes the session of the terminal in the second network.

[0170] Here, the type of the second network is different, and the type of session is also different. As an example, if the second network is a 4G network, the terminal can delete the terminal's PDN connection on the second network. If the second network is a 5G network, the terminal can delete the terminal's PDU session on the second network.

[0171] In some embodiments, the trigger condition satisfies at least one of the following:

[0172] Related to the state of the terminal in the first network and the state of the terminal in the second network;

[0173] Related to communication parameters of the first network;

[0174] related to communication parameters of the second network;

[0175] business-related;

[0176] Related to parameters of the terminal;

[0177] Related to the first indication information, the first indication information is used to indicate any of the following:

[0178] The network's interoperability architecture supports the N26 interface;

[0179] Supporting network redirection or switching of the terminal;

[0180] Supporting the terminal to switch from the first mode to the second mode;

[0181] Wherein, in the second mode, the terminal is associated with a single network.

[0182] This embodiment provides multiple aspects related to trigger conditions. Each of the aspects related to the trigger conditions will be described in detail below.

[0183] In some embodiments, when the trigger condition is related to the status of the terminal in the first network and the status of the terminal in the second network, the trigger condition includes at least one of the following:

[0184] The terminal is in an idle state in the first network and in an idle state in the second network;

[0185] The terminal is in a connected state in the second network and in an idle state in the first network;

[0186] The terminal is in a connected state in the first network and in an idle state in the second network.

[0187] This implementation may include the following three situations:

[0188] Case 1: The terminal is idle on the first network and idle on the second network. In this case, since the terminal is idle on both networks, it does not need to perform services on both networks. Therefore, the terminal can exit dual registration mode (or dual connection mode), which can reduce terminal complexity. In this case, the terminal can choose to detach or deregister from the first network, or detach or deregister from the second network.

[0189] Case 2: The terminal is in the connected state on the second network and in the idle state on the first network. In this case, since the terminal is in the idle state on the first network, the terminal does not need to perform services on the first network. Therefore, the terminal can choose to detach or deregister from the first network.

[0190] Case 3: The terminal is in the connected state on the first network and in the idle state on the second network. In this case, since the terminal is in the idle state on the second network, the terminal does not need to perform services on the second network. Therefore, the terminal can choose to detach or deregister from the second network.

[0191] In some embodiments, when the trigger condition is satisfied and is related to a parameter of the terminal, the trigger condition includes:

[0192] The battery level of the terminal is lower than or equal to a first threshold.

[0193] Here, if the terminal's battery level is less than or equal to the first threshold, it indicates that the terminal's battery level is low. When the terminal's battery level is low, to reduce power consumption, the terminal may choose to exit dual registration mode.

[0223] When the terminal is in the first mode and the triggering condition is met, the terminal detaches from or deregisters from the second network.

[0224] The aforementioned embodiments provide a basis for determining trigger conditions related to various communication parameters. The thresholds for each of the aforementioned communication parameters can be configured by the network-side device, meaning that the terminal can obtain these communication parameter thresholds from the network-side device. The thresholds for each communication parameter can also be configured by the terminal's application layer, meaning that the terminal can obtain these communication parameter thresholds from the application layer.

[0225] It should be noted that the basis for determining the triggering condition related to the communication parameters of the network is not limited to the aforementioned communication parameters, but may also be any other possible communication parameters.

[0226] In some embodiments, when the trigger condition is related to the service, the trigger condition includes at least one of the following:

[0227] The terminal executes or prepares to execute a first service that needs to be transmitted in the second network;

[0228] The terminal executes or prepares to execute a second service that needs to be transmitted in the first network;

[0229] The terminal executes or prepares to execute a third service, where the third service is a service with continuity requirements;

[0230] The terminal initiates or prepares to initiate a multimedia audio and video service or a multimedia communication service (collectively referred to as a multimedia voice service, such as an Internet Protocol Multimedia System (IP Multimedia Subsystem, IMS) voice service);

[0231] The terminal receives a call request for a multimedia audio and video service or a multimedia communication service (such as receiving an IMS INVITE message);

[0232] The terminal is executing or is currently performing (on-going) a multimedia audio and video service or a multimedia communication service.

[0233] This implementation may include the following situations:

[0234] Case 1: The terminal executes or prepares to execute a first service that needs to be transmitted in the second network. In this case, in order to ensure continuous transmission of the first service in the second network, the terminal may choose to detach from or deregister from the first network.

[0235] Case 2: The terminal executes or prepares to execute a second service that needs to be transmitted in the first network. In this case, in order to ensure continuous transmission of the second service in the first network, the terminal may choose to detach or deregister from the second network.

[0236] Case 3: The terminal executes or prepares to execute a third service, and the third service is a service with continuity requirements. In this case, in order to ensure the continuous processing of the service with continuity requirements, the terminal can choose to detach or deregister the first network, or choose to detach or deregister the second network. Whether the terminal chooses to detach or deregister the first network, or to detach or deregister the second network, can be determined based on the Internet Protocol address (IP) used by the third service. If the third service uses the IP of the first network, the terminal chooses to detach or deregister the second network; if the third service uses the IP of the second network, the terminal chooses to detach or deregister the first network.

[0237] It should be noted that service continuity requirements can be configured by network-side devices, meaning that the terminal can obtain service continuity requirements from the network-side devices. Service continuity requirements can also be configured by the terminal's application layer, meaning that the terminal can obtain service continuity requirements from the application layer.

[0238] Case 4: For multimedia audio and video services or multimedia communication services, the priority is usually higher, and it is usually necessary to maintain service continuity during the service processing. Therefore, whether the terminal initiates or prepares to initiate a multimedia voice service, receives a call request for a multimedia voice service, or is executing or performing a multimedia voice service, the terminal can choose to exit the dual registration mode. Whether the terminal chooses to detach or deregister the first network, or to detach or deregister the second network, can be determined based on the registration network of the multimedia voice service. If the terminal has registered for the multimedia voice service on the first network, the terminal chooses to detach or deregister the second network. If the terminal has registered for the multimedia voice service on the second network, the terminal chooses to detach or deregister the first network.

[0239] In some embodiments, when the trigger condition is satisfied and is related to the first indication information, the trigger condition includes:

[0240] The terminal receives the first indication information from a network side device.

[0241] In some embodiments, the method further comprises at least one of the following:

[0242] The terminal receives first configuration information, where the first configuration information comes from a network-side device;

[0243] The terminal obtains second configuration information, where the second configuration information comes from an application layer of the terminal;

[0244] The first configuration information includes at least one of the following:

[0245] The threshold value in the trigger condition;

[0246] Business information and business continuity requirements corresponding to the business information;

[0247] The second configuration information includes at least one of the following:

[0248] The threshold value in the trigger condition;

[0249] Business information and business continuity requirements corresponding to the business information.

[0250] For ease of understanding, the above-mentioned first configuration information, second configuration information, and first indication information can all be understood as auxiliary information. In this way, after receiving or obtaining these auxiliary information, the terminal can determine whether the trigger condition is met based on the auxiliary information, thereby determining whether to perform the first operation.

[0251] In some embodiments, the method further comprises:

[0252] The terminal performs a second operation, where the second operation includes:

[0253] The terminal switches the measurement information reporting mode from the first mode to the second mode;

[0254] The first manner includes prohibiting reporting of measurement information or reporting erroneous measurement information, and the second manner includes enabling reporting of measurement information or reporting correct measurement information or prohibiting reporting of erroneous measurement information.

[0255] In this implementation, when the terminal is in the first mode and the triggering condition is met, the terminal may further perform a second operation to implement switching of the measurement information reporting mode through the second operation.

[0256] The execution order of the first operation and the second operation is not limited. For example, the terminal may execute the first operation first and then execute the second operation; or the terminal may execute the second operation first and then execute the first operation.

[0257] In this implementation, by switching the measurement information reporting method, the terminal can report accurate measurement information, allowing the network device to perform network switching based on the correct measurement information, thereby improving the performance of the entire communication system. Furthermore, because the terminal can switch from dual registration mode to single registration mode when the trigger conditions are met, even if the network device may perform a network switch, the network switch will not cause service terminal or network anomalies.

[0258] In some embodiments, after the terminal switches the measurement information reporting mode from the first mode to the second mode, the method further includes at least one of:

[0259] The terminal reports correct measurement information of the second network to the first network;

[0260] The terminal reports correct measurement information of the first network to the second network.

[0261] The following uses a 4G network as the first network and a 5G network as the second network as an example to provide a specific embodiment to illustrate the network registration processing method of the embodiment of the present application. In this embodiment, the network registration processing method includes the following steps:

[0262] Step 0 (optional): The UE obtains relevant threshold information or service continuity requirements, such as local preset, network configuration (such as AMF sent through non-access stratum (NAS) message, or base station sent through radio resource control (RRC) message), application layer configuration (such as the UE application layer notifying the module in the UE for performing the first operation).

[0263] Furthermore, the UE may perform the following steps based on the indication of the network (such as AMF or MME) indicating support for the N26 interface or support for the N26 interface. For example, the following steps may be performed when the network indicates support for the N26 interface, and the following steps may not be performed when the network indicates not support for the N26 interface.

[0264] Step 1: The UE detects that at least one of the following conditions is met:

[0265] A0, signal quality is higher than or equal to the set threshold;

[0266] A1. Signal quality is lower than or equal to the set threshold;

[0270] B1. The data transmission rate is lower than or equal to the set threshold;

[0271] B0.1 / B1.1 refers to the data transmission rate in the 5G network;

[0272] B0.2 / B1.2 refers to the data transmission rate in the 4G network.

[0273] Furthermore, the above-mentioned data transmission rate may be the data transmission rate of the entire 5G network, or the data transmission rate of the entire 4G network, or the data transmission rate of a certain service in the 5G network, or the data transmission rate of a certain service in the 4G network.

[0274] C. The amount of data to be sent is lower than or equal to the set threshold;

[0275] C.1 refers to the amount of data to be sent in the 5G network;

[0276] C.2 refers to the amount of data to be sent in the 4G network.

[0277] D0, data waiting time is lower than or equal to the set threshold;

[0278] D1, data waiting time is higher than or equal to the set threshold;

[0279] D0.1 / D1.1 refers to the data waiting time in the 5G network;

[0280] D0.2 / D1.2 refers to the data waiting time in the 4G network.

[0281] E0, application layer QoE is higher than or equal to the set threshold;

[0282] E1, application layer QoE is lower than or equal to the set threshold;

[0283] E0.1 / E1.1, this application layer transmits data in 5G networks;

[0284] E0.2 / E1.2, this application layer transmits data in the 4G network.

[0285] F. Businesses with continuity requirements need to be enabled;

[0286] F1, means that data transmission in 5G network needs to be enabled;

[0287] F2: It means that data transmission in 4G network needs to be enabled.

[0288] G. The terminal enters the idle state;

[0289] G.1. The terminal enters the idle state of the 5G network;

[0290] G.2. The terminal enters the idle state of the 4G network.

[0291] H. Terminal power;

[0292] H.1. The terminal has sufficient power;

[0293] H.2. The terminal battery is low.

[0294] Step 2: The UE switches from dual registration mode to single registration mode. The UE performs at least one of the following operations:

[0295] Operation A: Detach on 4G, for example, by initiating a detach request.

[0296] Operation B: Delete the PDN connection in 4G, such as initiating a PDN Connection Release request;

[0297] Operation C: Deregister on 5G, such as initiating a deregistration request;

[0298] Operation D: Delete the PDU session in 5G, such as initiating a PDU Session Release request.

[0299] Operation A (and Operation B) can be performed when at least one of the following conditions is met: A0.1, A1.2, B0.1, B1.2, C.2, D0.1, D1.2, E0.1, E1.2, F.1, G.2, and H.2. Operation C (and Operation D) can be performed when at least one of the following conditions is met: A0.2, A1.1, B0.2, B1.1, C.1, D0.2, D1.1, E0.2, E1.1, F.2, G.1, and H.2.

[0300] In the above judgment, for the service triggering situation (such as conditions B0, B1, C, D0, D1, E0, E1 or F), if the service uses 5G IP, it is in the 5G network; if it uses 4G IP, it is in the 4G network.

[0301] Furthermore, if the IMS voice service is triggered, if the UE performs IMS registration in 5G, the IMS service is in the 5G network; if the UE performs IMS registration in 4G, the IMS service is in the 4G network.

[0302] In summary, the embodiments of the present application enable the terminal to exit the dual registration mode or dual connection mode when needed, ensuring that the terminal service will not be interrupted due to network switching and that the system will not be abnormal due to network switching.
