Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a paging method, device and electronic device. Background Art

[0002] The integration of the Internet of Things (IoT) and non-terrestrial networks (NTN), namely IoT NTN (Internet of Things Non-Terrestrial Network), provides communication solutions for scenarios where it is difficult to deploy terrestrial networks, such as remote areas, at sea, and in the air. Among them, the high-orbit satellite network, as part of IoT NTN, supports 2 / 3G network technologies such as GEO-Mobile Radio system, GERAN / UTRAN, etc. due to its wide coverage, enabling IoT devices to transmit small data and SMS communications in a large area, realizing a wider range of interconnected applications.

[0003] However, the IoT NTN terminals and ground networks (such as 4G LTE networks) in the related technologies are mainly designed with data transmission services in mind. For scenarios where a circuit domain fallback (CS fallback) mechanism is required to support voice services, the following major problems still exist: for example, the paging waiting time on the network side is usually statically configured, without considering the satellite communication environment in which the terminal is located. This is because the 2 / 3G network cannot understand the access type and paging feature requirements of the IoT NTN terminal in real time when performing voice called paging. Therefore, when the IoT NTN terminal accesses a high-latency high-orbit satellite network, the paging waiting time is too short, and the paging message may be considered to have timed out by the network before the terminal has completed receiving it, resulting in paging failure. For another example, when the IoT NTN terminal performs data services, in order to save energy, a longer discontinuous reception (DRX) cycle is usually configured, which is reasonable under static conditions. However, in dynamic scenarios where voice calls need to fall back to the 2G / 3G network, if the paging mechanism does not take into account the DRX cycle of the terminal and the additional propagation delay caused by high-orbit satellites, the risk of paging failure will increase, affecting user experience and communication service quality.

[0004] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] First, some nouns or terms that appear in the process of explaining the embodiments of the present application are subject to the following explanations:

[0036] IoT NTN (Internet of Things Non-Terrestrial Network): refers to the connection and data transmission of IoT devices through non-terrestrial networks, such as satellite networks. This technology is particularly suitable for areas with insufficient terrestrial network coverage, such as offshore, remote areas or high altitude areas, to provide continuous IoT services.

[0037] NB-IoT NTN (Narrowband Internet of Things Non-Terrestrial Network): refers to the communication of narrowband IoT devices through non-terrestrial networks, such as satellites. Among them, NB-IoT is a low-power wide area network technology designed specifically for IoT devices that require long battery life and long-range communications, while the NTN part extends its network access range, enabling it to communicate in areas where terrestrial networks are not available.

[0038] DRX (Discontinuous Reception): A power-saving mechanism that allows IoT devices or mobile terminals to turn off the receiver when they do not need to receive data to save power. The device turns on the receiver to receive paging information or other control messages during a predetermined period, thereby extending battery life while maintaining network connectivity.

[0039] MME (Mobility Management Entity): A core network component in 4G LTE networks that handles mobility management tasks such as user device registration, authentication, location update, and paging. In IoT NTN scenarios, MME is also responsible for coordinating the circuit domain fallback mechanism between the network and the terminal to ensure the continuity of voice services and the success rate of paging.

[0040] MSC / VLR (Mobile Switching Center / Visited Location Register): MSC is the core component in 2G / 3G networks, responsible for establishing, routing, and switching voice calls. VLR stores temporary user information, such as the user's current location and network registration status. In the circuit domain fallback mechanism of IoT NTN, MSC / VLR is used to process paging requests from MME and adjust the paging strategy according to the terminal's access type and paging assistance information.

[0041] EPS (Evolved Packet System): The core network architecture of 4G LTE network, which is based on all-IP packet switching technology to provide users with high-speed data services. In IoT NTN, EPS supports joint registration of terminals, that is, registering in 4G LTE network and 2 / 3G network at the same time, so as to flexibly switch between different networks.

[0042] IMSI (International Mobile Subscriber Identity): A digital code used to uniquely identify a mobile user in a mobile communication network. When a mobile terminal (such as a mobile phone or IoT device) accesses the network, the network uses the IMSI to confirm the user's identity and subscription information, and then provides corresponding services.

[0043] TA / LA (Tracking Area / Location Area): TA is a location management concept in 4G LTE networks, while LA is used in 2G / 3G networks. These areas are used to manage the location and mobility of UE (user equipment). When a UE moves from one TA / LA to another, a location update is required to ensure that the network can page the terminal correctly.

[0044] In order to solve the problem of poor paging efficiency in the related art, the present application embodiment provides a paging method, which can be run on Figure 1 In the computer terminal shown, the computer terminal is described below.

[0045] The paging method embodiment provided in the embodiment of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device.

[0046] It should be noted that the one or more processors and / or other data processing circuits described above may generally be referred to herein as "data processing circuits".

In addition, the data processing circuit may be a single independent processing module, or may be incorporated in whole or in part into any of the other components in the computer terminal 10. As described in the embodiments of the present application, the data processing circuit acts as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0047] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the paging method in the embodiment of the present application. The processor executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, the above-mentioned paging method is realized.

[0048] The transmission module 106 is used to receive or send data via a network.

In one example, the transmission module 106 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet.

[0049] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 .

[0050] It should be noted that, in some optional embodiments, the above Figure 1 The computer terminal shown may include hardware elements (including circuits), software elements (including computer code stored on a computer-readable medium), or a combination of hardware elements and software elements. It should be noted that Figure 1 This is merely one example of a particular embodiment and is intended to illustrate the types of components that may be present in the computer terminal described above.

[0051] In the above operating environment, an embodiment of the present application provides a paging method embodiment. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0052] Figure 2 is a flow chart of a paging method according to an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0053] Step S202: receiving a combined attach request sent by a terminal, wherein the combined attach request is used to indicate that the terminal supports circuit domain voice service capability, and the combined attach request carries requirement parameters of the terminal in a paging process.

[0054] In the above step S202, when the terminal performs joint attachment, the first network device (taking MME as an example) receives a joint attachment request from the terminal, which means that the terminal has the ability to access the 4G LTE network and the 2 / 3G network at the same time, and supports the circuit domain fallback mechanism to use voice services. Among them, the joint attachment request can also carry the terminal's demand parameters during the paging process, such as DRX (discontinuous reception mode) configuration, etc., to reflect the terminal's power consumption management requirements and network access characteristics.

[0055] Step S204, determine the first access type of the terminal, and generate first paging assistance information of the terminal according to the joint attachment request, wherein the first access type is used to indicate the way the terminal accesses the network during the joint attachment, and the first paging assistance information is used to indicate the specific paging requirement determined during the joint attachment.

[0056] In the above step S204, the MME determines to use the circuit domain fallback method for voice services, and determines the specific type of the terminal access network (such as IoT NTN), that is, the above first access type. At the same time, the MME can also generate the first paging auxiliary information according to the demand parameters in the joint attachment request, including but not limited to the paging time window, paging retry interval, paging retry number, propagation delay, etc., so that the MME can dynamically adjust the paging mechanism according to the current access environment and power consumption characteristics of the terminal to improve the success rate of paging, especially under the conditions of high latency and power consumption limitation.

[0057] Step S206: Send the first access type and the first paging assistance information, and receive target paging information generated according to the first access type and the first paging assistance information, wherein the target paging information is used to guide a paging operation for the terminal.

[0058] In the above step S206, the MME may send the determined first access type and the first paging assistance information to the second network device (taking MSC / VLR as an example) through the SGs interface. Subsequently, the MSC / VLR may retain or update its paging strategy for the terminal according to the received first access type and the first paging assistance information, generate target paging information, and ensure that the paging signal can be successfully and timely delivered to the terminal even under complex conditions of the satellite network.

[0059] Through the above steps S202 to S206, the purpose of avoiding paging failure caused by improper paging waiting time setting is achieved, thereby achieving the technical effect of improving the network paging success rate and optimizing the voice service experience in the circuit domain fallback scenario, thereby solving the technical problem that the 2 / 3G network in the related technology cannot understand the access type and paging characteristics of the terminal when performing circuit domain voice services, and is prone to paging failure due to a short paging waiting time. The following is a detailed description.

[0060] In the embodiment of the present application, a paging system corresponding to the above-mentioned paging method and integrating satellite communication and terrestrial 2 / 3G network is also provided, aiming to provide services for dual-mode single-standby terminals with 2 / 3G and NB-IoT NTN capabilities, such as Figure 3 The system may include:

[0061] Terminal (such as IoT NTN UE): A dual-mode single-standby terminal that supports 2 / 3G and NB-IoT NTN capabilities. When the UE accesses the 4G LTE network via satellite, it can initiate a joint attachment request and receive network-side instructions to perform circuit domain fallback.

[0062] 2 / 3G base station, eNodeB base station: responsible for handling wireless communication between UE and network. For example, receiving the joint attach request from UE and forwarding it to MME.

[0063] MME: is used to determine the RAT access type of the terminal, determine the paging assistance information (including but not limited to the paging time window, paging retry interval, paging retry number, propagation delay, etc.), and transmit this information to the MSC / VLR.

[0064] MSC / VLR: Used to receive RAT access type and paging assistance information from MME, and perform subsequent voice call paging processing based on this information.

[0065] SGs interface: The interface between MME and MSC / VLR, used to transmit the RAT access type and paging assistance information of the terminal.

[0066] In general, the terminal is connected to the 2 / 3G base station on the ground via satellite, and interacts with MSC / VLR to process voice services. At the same time, it exchanges RAT access type and paging assistance information with MME through the SGs interface to optimize the paging process and prevent paging failure. The arrow line from the terminal to MSC / VLR represents the voice service path, and the arrow line from the terminal to MME represents the IoT NTN data service path, showing how the terminal switches between different networks to achieve continuity of voice and data services.

[0067] In the embodiment of the present application, the key mechanism for supporting IoT NTN terminals to perform circuit domain (CS) voice service fallback between non-terrestrial networks (such as satellite networks) and terrestrial networks mainly involves the terminal's joint attachment process, joint location update process and paging process. Figure 4-6 These three processes are analyzed in detail.

[0068] Figure 4 is a schematic diagram of a joint attachment process according to an embodiment of the present application, and Figure 2 The process in more detail shows how the first network device (taking MME as an example) intelligently adjusts the paging strategy according to the access type and technical characteristics of the terminal, especially in the complex environment of IoT NTN terminals and satellite networks. The specific steps can be as follows:

[0069] S1: IoT NTN UE (dual-mode single standby terminal with 2 / 3G and NB-IoT NTN capabilities) accesses the 4G LTE network via satellite and sends an EPS / IMSI joint attachment request to the network. The joint attachment request indicates that the UE has the ability to support circuit domain voice services and can carry the UE's required parameters during paging, such as DRX (discontinuous reception mode) configuration, to adapt to the high latency and power consumption management requirements of the satellite network.

[0070] S2: Receive the joint attachment request sent by the UE through a base station device (such as an eNodeB base station in a 4G LTE network), forward it to the MME, and start the LTE attachment process.

[0071] S3: After receiving the joint attachment request forwarded by the eNodeB, the MME identifies that the RAT access type of the UE is IoTNTN, that is, the first access type mentioned above; and generates the first paging assistance information based on the demand parameters provided by the UE, including but not limited to the paging time window, paging retry interval, number of paging retries, etc., to ensure that the paging strategy adapts to the satellite environment.

[0072] S4: MME may send the first access type and the first paging assistance information to MSC / VLR through the SG interface, so that the 2 / 3G network can adjust the paging strategy based on the characteristics of the IoT NTN terminal. It should be noted that this process may involve a joint location update operation. When a joint location update occurs, it is necessary to determine whether the first access type and the first paging assistance information are updated.

[0073] S5: After receiving the first access type and the first paging assistance information transmitted by the MME, the MSC / VLR determines whether it is necessary to adjust the first access type and the first paging assistance information according to the actual situation, and generates the final target paging information, wherein the target paging information is used for subsequent voice called paging to ensure that the paging instruction can be accurately executed based on the specific needs of the IoT NTN terminal.

[0074] S6: When the UE initiates a location update, whether it is a tracking area (TA) update or a location area (LA) update, the MME will update the first access type and the first paging assistance information and pass them to the MSC / VLR. The latter will update the paging policy based on this information and perform a circuit domain location update to ensure that the network always has the latest location and access characteristics of the UE.

[0075] S7: After the UE successfully updates its location, the MME receives a location update acceptance confirmation returned by the MSC / VLR, which carries the updated target paging information.

[0076] S8: After receiving the location update acceptance confirmation, the MME adjusts the relevant DRX and other paging demand parameters as needed according to the updated target paging information.

[0077] S9: MME returns an attach accept message to UE through eNodeB. This attach accept message not only confirms that the UE's attach request has been accepted, indicating that the UE has successfully attached and updated to the 2 / 3G network, but also carries the paging requirement parameters such as DRX determined by the network side to ensure the smooth progress of subsequent paging operations.

[0078] Optionally, the joint location update process includes: receiving a joint location update request sent by the terminal, wherein the joint location update request carries the terminal's requirement parameters during the paging process; determining the second access type of the terminal, and generating second paging assistance information of the terminal based on the joint location update request, wherein the second access type is used to indicate the way in which the terminal accesses the network during the joint location update, and the second paging assistance information is used to indicate the specific paging requirement determined during the joint location update; sending the second access type and the second paging assistance information, and receiving the first paging update information obtained after updating the target paging information based on the second access type and the second paging assistance information.

[0079] Figure 5 is a schematic diagram of a joint location update process according to an embodiment of the present application, such as Figure 5As shown in the figure, the joint location update and paging demand parameters of IoT NTN terminals can be reflected to the network side in real time and accurately, and dynamically updated and optimized in MSC / VLR. This mechanism ensures efficient and reliable paging even under complex satellite network conditions, thereby supporting seamless switching of terminals between non-terrestrial networks and terrestrial networks, and ensuring the continuity of circuit domain voice services and user experience. The specific steps can be as follows:

[0080] S1: When the UE updates the TA or LA location, it sends a (joint) location update request to the MME, wherein the joint location update request may carry the UE's requirement parameters during the paging process, such as DRX (discontinuous reception mode) configuration, to reflect the UE's latest requirements during the paging process.

[0081] S2: After receiving the location update request, the MME starts the location update process of the LTE network and processes the UE's mobility information and paging requirement parameters.

[0082] S3: The MME determines whether the current RAT access type and paging assistance information need to be updated according to the actual situation. If update is required, the second access type of the UE is re-determined, and the second paging assistance information is generated according to the above (joint) location update request, including but not limited to the paging time window, paging retry interval and number, so as to optimize the paging efficiency under satellite access conditions.

[0083] S4: The MME communicates with the MSC / VLR through the SG interface, and transmits the second access type and the second paging auxiliary information to the MSC / VLR, so as to ensure that the core device of the 2 / 3G network has the latest information of the UE.

[0084] S5: After receiving the second access type and the second paging assistance information transmitted by the MME, the MSC / VLR adjusts the terminal location information and paging parameter configuration stored internally, that is, the above-mentioned target paging information, as needed, and generates the first paging update information to reflect the paging demand of the UE under the new access type.

[0090] Figure 6 is a schematic diagram of a called party paging process according to an embodiment of the present application, such as Figure 6 As shown in the figure, the network can dynamically optimize the paging strategy according to the latest status and needs of the UE, thereby ensuring the continuity and quality of circuit domain voice services. Through the close collaboration between MME, eNodeB, and MSC / VLR, the entire paging process achieves a high degree of matching between terminal needs and network conditions, and optimizes the paging experience of IoT NTN terminals in the NTN network. The specific steps can be as follows:

[0091] S1: When a voice call is made by a UE, the MSC / VLR, as the core device of the 2G / 3G network, initiates a call request and prepares for a paging operation.

[0092] S2: The MME receives a paging request, where the paging request may carry relevant requirement parameters of the UE during the paging process.

[0093] S3: MME determines whether the current RAT access type and paging assistance information need to be updated according to the actual situation. If update is required, the third access type of the UE is re-determined, and the third paging assistance information is generated according to the above paging request, including but not limited to the paging time window, paging retry interval and number, to meet the special needs of IoT NTN terminals in satellite networks.

[0094] S4: The MME communicates with the MSC / VLR through the SG interface, and transmits the third access type and the third paging auxiliary information to the MSC / VLR, so as to ensure that the core device of the 2 / 3G network has the latest information of the UE.

[0095] S5: After receiving the third access type and the third paging assistance information transmitted by the MME, the MSC / VLR adjusts the terminal location information and paging parameter configuration stored internally, that is, the above-mentioned target paging information, as needed, generates second paging update information, and returns it to the MME to reflect the adjustments made by the network to adapt to the current access type and paging requirements of the UE.

[0096] S6: The MME initiates paging to the eNodeB based on the finally determined second paging update information.

[0097] S7: The eNodeB initiates paging to the UE.

[0098] Optionally, the overall paging operation may include: performing a paging operation according to target paging information, first paging update information, or second paging update information.

[0099] In the embodiment of the present application, when the network side performs the paging operation, the use of the target paging information, the first paging update information or the second paging update information reflects the multi-level optimization and dynamic adjustment capabilities of the paging strategy. Specifically:

[0100] In the initial state (such as the joint attachment state), the core equipment of the network (such as MME or MSC / VLR) will perform paging operations based on the target paging information. This target paging information is usually generated based on the standard configuration or the current RAT access type and paging assistance information of the terminal, and is applicable to most terminals and network conditions.

[0101] The first paging update information is generated by the network according to the second access type and the second paging assistance information provided by the terminal when the terminal performs a joint location update. When the MME or MSC / VLR receives these update information, it will adjust its paging strategy to adapt to the current network environment and power consumption management requirements of the terminal. For example, for IoT NTN terminals accessed via satellite, the first paging update information may indicate an extension of the paging time window to overcome the delay of satellite communication and reduce unnecessary power consumption of the terminal.

[0102] The second paging update information is dynamically generated according to the third access type and the third paging assistance information of the terminal when the network side receives the paging request. When the MME or MSC / VLR receives these update information, it will adjust its paging strategy to ensure that the paging operation can still be successfully performed even when the UE moves or the network conditions change. For example, if the UE moves from a non-terrestrial network (satellite network) to a terrestrial network, the second paging update information may indicate the restoration of standard paging parameters to adapt to the faster terrestrial network response time.

[0103] Optionally, the first paging assistance information, the second paging assistance information, the third paging assistance information, the target paging information, the first paging update information or the second paging update information includes at least one of the following: a paging time window of the terminal, a paging retry interval, a paging retry number and a propagation delay.

[0104] In the embodiment of the present application, whether it is the first paging assistance information and target paging information generated based on the joint attachment request, or the second paging assistance information and the third paging assistance information generated based on the joint location update request or the called paging request, and the first paging update information or the second paging update information subsequently adjusted based on the network status and terminal needs, at least one or more parameters of the terminal's paging time window, paging retry interval, paging retry number and propagation delay are included. These parameters are crucial components of the paging mechanism, and they directly affect the efficiency and success rate of the network paging UE, especially in the IoT NTN (non-terrestrial network) scenario, due to the high latency and power consumption management requirements brought by satellite communications, the appropriate adjustment of the paging strategy becomes particularly important.

[0105] By dynamically adjusting these parameters, the network can better adapt to the characteristics of IoT NTN terminals accessing the network at different times and locations, ensuring that terminals can be effectively paged even in high-latency satellite networks, avoiding paging failures due to excessive propagation delays. At the same time, by adjusting the paging retry interval and number, the utilization of network resources is optimized, unnecessary energy consumption is reduced, and the performance of the entire system and user experience are improved.

[0106] Optionally, the method further includes: returning the demand parameter to the terminal; or adjusting the demand parameter according to the target paging information, the first paging update information or the second paging update information, and returning the adjusted demand parameter to the terminal.

[0107] In the embodiments of the present application, Figure 4-6 As shown, two-way communication between the network and the terminal can also be introduced in the optimization of the paging mechanism to enhance the flexibility and intelligence of the system. Specifically, by returning the demand parameters to the terminal, or adjusting the demand parameters according to the target paging information, the first paging update information, and the second paging update information and then returning them to the terminal, the network can not only adapt to the current state of the terminal, but also guide the terminal to adjust its power consumption management strategy to better cooperate with the paging operation of the network. Under this mechanism, the network dynamically adjusts parameters such as the paging time window, retry interval, and number according to the characteristics of satellite communications (such as high latency), and feeds back these adjusted parameters to the terminal, so that the terminal can adjust its DRX cycle or other power consumption management settings according to the network instructions, thereby maximizing the battery life of the terminal while ensuring the paging success rate.

[0108] Figure 7is a flow chart of a paging method according to an embodiment of the present application, such as Figure 7 As shown, the method comprises the following steps:

[0109] Step S702, receiving a first access type and first paging assistance information, wherein the first access type is used to indicate a way in which the terminal accesses the network during joint attachment, the first paging assistance information is used to indicate a specific paging requirement determined during joint attachment, and the first paging assistance information is determined based on a joint attachment request generated by the terminal, the joint attachment request is used to indicate that the terminal supports circuit domain voice service capabilities, and the joint attachment request carries the terminal's requirement parameters during the paging process.

[0110] In the above step S702, the process of the second network device (taking MSC / VLR as an example) receiving the first access type and the first paging assistance information occurs when the terminal accesses the LTE network through the satellite network and initiates a joint attachment request, wherein the terminal will clearly indicate in the joint attachment request that it supports circuit domain voice service capabilities, and can carry its demand parameters in the paging process, including but not limited to the paging time window, paging retry interval, number of paging retries and propagation delay, etc., to inform the network of its specific paging requirements. Prior to this, after receiving the attachment request, the first network device (taking MME as an example) will determine that the access type of the terminal is IoT NTN, and determine the first paging assistance information based on the demand parameters provided by the terminal. Subsequently, the MME transmits the first access type and the first paging assistance information to the MSC / VLR through the SG interface.

[0111] Step S704: Generate target paging information according to the first access type and the first paging auxiliary information, and store and send the target paging information, wherein the target paging information is used to guide a paging operation for the terminal.

[0112] In the above step S704, after receiving the first access type and the first paging assistance information sent by the MME, the MSC / VLR will adjust the first access type and the first paging assistance information as needed, update or retain its paging strategy for the terminal, and generate target paging information. The adjustment of the parameters is to meet the special requirements of the terminal when accessing through the satellite network, such as high latency and power consumption management. Subsequently, the MSC / VLR stores the generated target paging information for use in subsequent paging operations, and sends the target paging information to relevant components in the network, such as the MME and eNodeB, to guide them to perform paging operations.

[0113] Through the above steps S702 to S704, the purpose of avoiding paging failure caused by improper paging waiting time setting is achieved, thereby achieving the technical effect of improving the network paging success rate and optimizing the voice service experience in the circuit domain fallback scenario, thereby solving the technical problem that the 2 / 3G network in the related technology cannot understand the access type and paging characteristics of the terminal when performing circuit domain voice services, and is prone to paging failure due to a short paging waiting time. The following is a detailed description.

[0114] In the embodiment of the present application, the key mechanism to support IoT NTN terminals to perform circuit domain (CS) voice service fallback between non-terrestrial networks (such as satellite networks) and terrestrial networks mainly involves joint attachment process, joint location update process and paging process. Specifically:

[0115] Terminal joint attachment process and Figure 7 The process in corresponds to that in Figure 4 The explanation of the joint attach procedure with MME as the execution subject in is also applicable to the joint attach procedure with MSC / VLR as the execution subject here. Figure 4 It also shows how MSC / VLR intelligently adjusts the paging strategy according to the access type and technical characteristics of the terminal in the complex environment of IoT NTN terminals and satellite networks, which will not be repeated here.

[0116] The joint location update process of the terminal includes: receiving a second access type and a second paging assistance information, wherein the second access type is used to indicate the way in which the terminal accesses the network during the joint location update, the second paging assistance information is used to indicate the specific paging requirement determined during the joint location update, and the second paging assistance information is determined based on a joint location update request generated by the terminal, and the joint location update request carries the required parameters of the terminal during the paging process; updating the target paging information based on the second access type and the second paging assistance information to obtain the first paging update information, and storing and sending the first paging update information.

[0117] It should be noted that Figure 5 The explanation of the joint location update procedure with MME as the execution subject in is also applicable to the joint location update procedure with MSC / VLR as the execution subject here. Figure 5 As shown, the joint location update and paging demand parameters of the IoT NTN terminal can be reflected to the network side in real time and accurately, and dynamically updated and optimized in the MSC / VLR, which will not be repeated here.

[0118] The called party paging process includes: receiving a third access type and third paging auxiliary information, wherein the third access type is used to indicate the way in which the terminal accesses the network when a paging request sent by the network side is received, and the third paging auxiliary information is used to indicate the specific paging requirement determined when the paging request is received; updating the target paging information according to the third access type and the third paging auxiliary information to obtain second paging update information, and storing and sending the second paging update information.

[0119] It should be noted that Figure 6 The explanation of the called party paging process in the above text with MME as the execution subject is also applicable to the called party paging process here with MSC / VLR as the execution subject. Figure 6 As shown in the figure, through the close collaboration between MSC / VLR, MME and eNodeB, the entire paging process achieves a high degree of matching between terminal requirements and network conditions, and optimizes the paging experience of IoT NTN terminals in the NTN network. It will not be repeated here.

[0120] Optionally, the overall paging operation may include: performing a paging operation according to target paging information, first paging update information, or second paging update information.

[0121] In an embodiment of the present application, a paging operation is performed according to the target paging information, the first paging update information or the second paging update information, which reflects the dynamic and adaptability of the paging mechanism of the present application. Specifically, when the IoT NTN terminal accesses the network via satellite and supports circuit domain voice services, the network side receives the access type and paging requirement parameters of the terminal through the MME to generate the initial target paging information. However, the network environment and terminal status are dynamically changing, especially in the context of high latency of satellite communication and terminal power consumption management requirements, the paging parameters may need to be adjusted according to the real-time situation. Therefore, the network side may also optimize the paging operation based on the first paging update information (such as in the location update process) or the second paging update information (such as in the called paging process). This mechanism allows the network to intelligently adjust the paging time window, retry interval, number of retries and other parameters when the terminal is attached, the location changes or the paging request is made, ensuring that the paging operation not only meets the terminal requirements at the time of initial attachment, but also can continuously and efficiently perform paging when the terminal moves or the network conditions change, avoiding paging failures caused by parameter mismatch, thereby improving the continuity of voice services and user experience.

[0122] Optionally, the first paging assistance information, the second paging assistance information, the third paging assistance information, the target paging information, the first paging update information or the second paging update information includes at least one of the following: a paging time window of the terminal, a paging retry interval, a paging retry number and a propagation delay.

[0123] In the embodiment of the present application, whether it is the first paging assistance information and target paging information generated based on the joint attachment request, or the second paging assistance information and the third paging assistance information generated based on the joint location update request or the called paging request, and the first paging update information or the second paging update information subsequently adjusted based on the network status and terminal needs, at least one or more parameters of the terminal's paging time window, paging retry interval, paging retry number and propagation delay are included. These parameters are crucial components of the paging mechanism, and they directly affect the efficiency and success rate of the network paging UE, especially in the IoT NTN (non-terrestrial network) scenario, due to the high latency and power consumption management requirements brought by satellite communications, the appropriate adjustment of the paging strategy becomes particularly important.

[0124] By dynamically adjusting these parameters, the network can better adapt to the characteristics of IoT NTN terminals accessing the network at different times and locations, ensuring that terminals can be effectively paged even in high-latency satellite networks, avoiding paging failures due to excessive propagation delays. At the same time, by adjusting the paging retry interval and number, the utilization of network resources is optimized, unnecessary energy consumption is reduced, and the performance of the entire system and user experience are improved.
