Description

Processing method, communication device and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a processing method, communication equipment and storage medium. Background Art

[0002] In existing protocols, processes that interact with the core network, such as the ATTACH procedure, TAU procedure, Initial Context Setup procedure, and E-RAB signaling procedure, require both an air interface connection between the terminal device and network equipment (e.g., base station), and an S1 interface connection between the network equipment (e.g., base station) and the core network equipment. Traditional signaling / service processes require that network equipment (e.g., base station) promptly transmit received signaling or data to the corresponding network element, which then promptly acknowledges or responds. Subsequent processes cannot proceed until confirmation or response is received from the corresponding network element.

[0003] In the satellite store-and-forward mode, network equipment (such as base stations) are deployed on the satellite (full eNB as regenerative payload). Due to the movement of the satellite, the connection between the terminal device and the satellite, and the connection between the satellite and the core network equipment may not exist at the same time. Therefore, the satellite needs to first store the NAS (Non-Access Stratum) signaling or data from the terminal device or core network equipment, and then send the stored NAS signaling or data to the corresponding network element when the connection is restored.

[0004] During the process of conceiving and implementing this application, the inventors discovered that there are at least the following problems: in the satellite store-and-forward mode, if traditional signaling / business processes are used, it is impossible to ensure normal interaction between terminal devices, network devices and / or core network devices, thereby preventing the business from proceeding normally.

[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Technical Solutions

[0126] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”.

[0135] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0136] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0137] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and / or other components. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G and 6G, etc.

[0138] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0139] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0140] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0141] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0142] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0143] The user input unit 107 can be used to receive input digital or character information and generate key signal input related to user settings and function control of the mobile terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072.

[0164] 5 , which is a schematic diagram of the overall flow of interaction between a terminal device, a network device (such as a satellite) and a core network device involved in the processing method of an embodiment of the present application.

[0165] As shown in Figure 5, the network system architecture includes: terminal equipment, at least one service satellite (eNB1, eNB2, eNB3, etc.), and core network equipment. The overall process includes:

[0166] Step 1: The current serving satellite (eNB1) operates in store-and-forward mode (i.e., there is no feeder link / S1 connection between eNB1 and the ground station).

[0167] Step 2: The current serving satellite (eNB1) receives and stores the uplink NAS signaling and / or data sent by the terminal device.

[0168] Step 3: The current serving satellite (eNB1) sends an RRC release (radio resource control release) message to the terminal device. The RRC release message carries satellite (base station, such as eNB2) information or time information.

[0169] Optionally, the satellite information carried in the RRC release message indicates the satellite (base station) information at which the terminal device (expects) to (attempt) to receive or delay receiving downlink NAS signaling and / or data next time, or to monitor paging or initiate an access request. This information may include at least one satellite information.

[0170] Or the satellite information carried in the RRC release message indicates the satellite (base station) information that carries downlink NAS signaling and / or data or the terminal device starts monitoring paging or initiates an access request. The information may include at least one satellite information.

[0171] Or the time information carried in the RRC release message indicates the time information when the terminal device (expects) to (attempt) to receive downlink NAS signaling and / or data next time, or monitor paging or initiate an access request.

[0172] Or the time information carried in the RRC release message indicates the time information when the downlink NAS signaling and / or data or the terminal device starts monitoring paging or initiating an access request.

[0173] Step 4: The terminal device receives the RRC release message and saves the context information.

[0174] When the information carried by the RRC release message is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information arrives; after the time indicated by the time information arrives, the terminal device starts monitoring paging or initiates an access request.

[0175] When the satellite information is an eNBID or a cell ID, the terminal device does not monitor paging or initiate an access request before the terminal device reselects the eNB or the cell; after the terminal device reselects the eNB or the cell, the terminal device starts to monitor paging or initiate an access request.

[0176] When the satellite information is ephemeris information, the terminal device confirms or predicts the time when the satellite will start providing service based on the ephemeris information and the terminal device's location information. Before the satellite starts providing service, the terminal device does not monitor for paging or initiate access requests. After the satellite starts providing service, the terminal device begins monitoring for paging or initiating access requests.

[0177] When the satellite information is the satellite service start time, the terminal device does not monitor paging or initiate access requests before the satellite service start time arrives; after the satellite service start time arrives, the terminal device starts monitoring paging or initiates access requests.

[0178] Step 5: After the current serving satellite (eNB1) restores the feeder link / S1 connection with the ground station, the stored uplink NAS signaling and / or data, satellite information (such as eNB2) / time information, terminal device location information, and terminal device context information are sent to the core network device.

[0179] Step 6: The core network device sends downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information to the next satellite providing service (such as eNB2) based on the satellite information / time information provided by the current serving satellite (eNB1).

[0180] Step 7: The next satellite providing service (such as eNB2) stores the received downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information, and triggers paging or receives the terminal device's access request after moving to the terminal device location area or the time arrives.

[0181] Repeat steps 2 to 7.

[0182] First embodiment

[0183] 6 , which is a flow chart of a processing method according to a first embodiment of the present application, the processing method according to the embodiment of the present application can be applied to a network device (such as a satellite), which can be a first network node. The method includes the following steps:

[0184] S1: A first network node sends first information to a terminal device, so that the terminal device performs a first operation based on the first information.

[0185] The solution of this embodiment is mainly applied to scenarios of satellite store-and-forward mode.

[0186] In the satellite store-and-forward mode, network equipment (such as base stations) is deployed on the satellite. When the network equipment (such as base stations) operates in the store-and-forward mode, there is no feeder link connection between the satellite and the ground station.

[0187] Due to satellite movement, the connection between the terminal device and the satellite, and between the satellite and the core network equipment may not exist at the same time. Therefore, the satellite needs to first store the NAS signaling or data from the terminal device or core network equipment, and then send the stored NAS signaling or data to the corresponding network element when the connection is restored.

[0188] Traditional signaling / business processes require network equipment (such as base stations) to send signaling or data to the corresponding network element in a timely manner after receiving it, and the corresponding network element must promptly confirm or respond. Subsequent processes cannot be carried out before receiving confirmation or response from the corresponding network element.

[0189] In the satellite store-and-forward mode, if traditional signaling / service processes are used, it is impossible to ensure normal interaction between terminal devices, network devices and / or core network devices, resulting in the inability to carry out normal services.

[0190] Therefore, the solution of this embodiment proposes a signaling / service process to ensure normal interaction between terminal devices, network devices and / or core network devices, so that the business can proceed normally.

[0191] Optionally, in this embodiment, the network device includes a first network node and / or a second network node.

[0193] Optionally, the first network node receives and stores uplink NAS signaling and / or data sent by the terminal device.

[0194] In this embodiment, the first network node sends first information to the terminal device, so that the terminal device performs a first operation based on the first information.

[0195] Optionally, the first information may be a system message or other downlink message.

[0196] Optionally, the first information is an RRC release (radio resource control release) message.

[0198] Optionally, the terminal device receives the RRC release message and saves the context information.

[0199] Optionally, the first information includes at least one of the following:

[0200] Second network node information or time information for next (attempt) receiving or delayed receiving of the second information;

[0201] Second network node information or time information of the terminal device monitoring paging and / or initiating access request;

[0203] Optionally, there may be at least one second network node.

[0204] Optionally, the second network node information includes information of at least one network node.

[0205] Optionally, the second information includes downlink NAS signaling and / or data.

[0206] Optionally, the second network node information includes at least one of a base station identifier, a cell identifier, ephemeris information, and a time when the second network node starts to provide a service.

[0207] Optionally, the terminal device performs a first operation based on the first information, including at least one of the following:

[0208] When the first information is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information is reached, and the terminal device starts monitoring paging or initiates an access request after the time indicated by the time information is reached;

[0209] When the second network node information is a base station identifier and / or a cell identifier, before the terminal device reselects the base station or cell, the terminal device does not monitor paging or initiate an access request. After the terminal device reselects the base station or cell, the terminal device starts monitoring paging or initiating an access request.

[0210] When the second network node information is ephemeris information, the terminal device confirms or predicts the time when the second network node starts providing services based on the ephemeris information and / or the terminal device location information. Before the time for starting to provide services arrives, the terminal device does not monitor paging or initiate an access request. After the time for starting to provide services arrives, the terminal device starts monitoring paging or initiates an access request.

[0211] When the second network node information is the time when the second network node starts to provide services, the terminal device does not monitor paging or initiate an access request before the time when the service starts to be provided arrives, and the terminal device starts to monitor paging or initiate an access request after the time when the service starts to be provided arrives.

[0212] Taking Figure 5 as an example, the first network node is the current serving satellite (eNB1), and the second network node is the next serving satellite (eNB2, eNB3, etc.). The interaction process between the first network node and the terminal device is as follows:

[0213] Step 1: The current serving satellite (eNB1) (ie, the first network node) operates in store-and-forward mode (ie, there is no feeder link / S1 connection between eNB1 and the ground station).

[0214] Step 2: The current serving satellite (eNB1) receives and stores the uplink NAS signaling and / or data sent by the terminal device.

[0215] Step 3: The current serving satellite (eNB1) sends an RRC release (radio resource control release) message to the terminal device. The RRC release message carries satellite (base station, such as eNB2) information or time information.

[0216] Optionally, the information carried by the RRC release message indicates the satellite (base station) information that the terminal device (expects) to (attempt) receive / delay receiving downlink NAS signaling and / or data or monitor paging or initiate an access request next time, and / or, the information carried by the RRC release message indicates the satellite (base station) information that carries downlink NAS signaling and / or data, or the terminal device starts monitoring paging or the terminal device initiates an access request, that is, the second network node information.

[0217] Optionally, the information carried in the RRC release message may include at least one satellite information.

[0218] Optionally, the information carried in the RRC release message indicates the time information of the terminal device (expected) next (attempt) to receive downlink NAS signaling and / or data, or monitor paging or initiate an access request.

[0219] Optionally, the information carried in the RRC release message indicates the time information of carrying downlink NAS signaling and / or data, or when the terminal device starts monitoring paging or initiates an access request.

[0220] Optionally, the satellite information may be at least one of the following: eNB ID, cell ID, satellite ephemeris information, and satellite service start time.

[0221] Optionally, the current serving satellite knows when to restore the feeder link connection with the ground station and send the stored uplink NAS signaling and / or data to the core network device, when there will be downlink feedback signaling and / or data from the core network device, and which satellites will provide services to the terminal device next, so it can be confirmed which satellites can carry the downlink NAS signaling and / or data of the core network device.

[0222] Step 4: The terminal device receives the RRC release message and saves the context information.

[0223] When the information carried by the RRC release message is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information arrives; after the time indicated by the time information arrives, the terminal device starts monitoring paging or initiates an access request.

[0224] Optionally, when the satellite information is an eNB ID or a cell ID, before the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device does not monitor paging or initiate an access request; after the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device starts to monitor paging or initiate an access request.

[0225] Optionally, when the satellite information is ephemeris information, the terminal device confirms or predicts the time when the satellite (such as eNB2) starts to provide services based on the ephemeris information and the terminal device location information. Before the time when the satellite starts to provide services, the terminal device does not monitor paging or the terminal device does not initiate an access request. After the time when the satellite starts providing services arrives, the terminal device starts monitoring paging or initiates an access request.

[0226] Optionally, when the satellite information is the satellite service start time, the terminal device does not monitor paging or initiate an access request before the satellite service start time arrives, and the terminal device starts monitoring paging or initiates an access request after the satellite service start time arrives.

[0227] Through the technical solution of this embodiment, the first network node sends the first information to the terminal device, so that the terminal device performs the first operation based on the first information. In the satellite store-and-forward mode, it can ensure that the terminal device and the network device can interact normally, so that the service can proceed normally.

[0228] Second embodiment

[0229] Based on the first embodiment of the present application, the second embodiment of the present application proposes a processing method, which mainly explains the processing method of the interaction process between the first network node, the core network device and the second network node after the first network node restores the feeder link and / or S1 connection.

[0240] Optionally, the core network device sends downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information to the next satellite providing service (such as eNB2), i.e., the second network node, based on the second network node information or time information provided by the first network node (current serving satellite).

[0241] Optionally, the next second network node providing service stores the received downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information, and triggers paging or receives an access request from the terminal device after moving to the terminal device location area or the time arrives.

[0242] Taking Figure 5 as an example, the first network node is the current serving satellite (eNB1), and the second network node is the next serving satellite (eNB2, eNB3, etc.). The interaction process between the first network node and the terminal device, the core network device, and the second network node is as follows:

[0243] Step 1: The current serving satellite (eNB1) (ie, the first network node) operates in store-and-forward mode (ie, there is no feeder link / S1 connection between eNB1 and the ground station).

[0244] Step 2: The current serving satellite (eNB1) receives and stores the uplink NAS signaling and / or data sent by the terminal device.

[0245] Step 3: The current serving satellite (eNB1) sends an RRC release (radio resource control release) message to the terminal device. The RRC release message carries satellite (base station, such as eNB2) information or time information.

[0246] Optionally, the information carried by the RRC release message indicates the satellite (base station) information that the terminal device (expects) to (attempt) receive / delay receiving downlink NAS signaling and / or data or monitor paging or initiate an access request next time, and / or, the information carried by the RRC release message indicates the satellite (base station) information that carries downlink NAS signaling and / or data, or the terminal device starts monitoring paging or the terminal device initiates an access request, that is, the second network node information.

[0263] S3: The core network device receives third information, where the third information is sent by the first network node to the core network device in response to the first condition being met.

[0264] The solution of this embodiment is mainly applied to scenarios of satellite store-and-forward mode.

[0265] In the satellite store-and-forward mode, network equipment (such as base stations) is deployed on the satellite. When the network equipment (such as base stations) operates in the store-and-forward mode, there is no feeder link connection between the satellite and the ground station.

[0266] Due to satellite movement, the connection between the terminal device and the satellite, and between the satellite and the core network equipment may not exist at the same time. Therefore, the satellite needs to first store the NAS signaling or data from the terminal device or core network equipment, and then send the stored NAS signaling or data to the corresponding network element when the connection is restored.

[0267] Traditional signaling / business processes require network equipment (such as base stations) to send signaling or data to the corresponding network element in a timely manner after receiving it, and the corresponding network element must promptly confirm or respond. Subsequent processes cannot be carried out before receiving confirmation or response from the corresponding network element.

[0268] In the satellite store-and-forward mode, if traditional signaling / service processes are used, it is impossible to ensure normal interaction between terminal devices, network devices and / or core network devices, resulting in the inability to carry out normal services.

[0269] Therefore, this embodiment proposes a signaling / service process to ensure normal interaction between terminal devices, network devices and / or core network devices, so that services can proceed normally. In this embodiment, the network devices include a first network node and / or a second network node.

[0270] Optionally, the first network node operates in a store-and-forward mode, that is, there is no feeder link / S1 connection between the first network node and the ground station.

[0271] In this embodiment, in response to the first condition being met, the first network node sends the third information to the core network device, and the core network device receives the third information.

[0286] Optionally, the terminal device performs a first operation based on the first information, including at least one of the following:

[0287] When the first information is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information is reached, and the terminal device starts monitoring paging or initiates an access request after the time indicated by the time information is reached;

[0288] When the second network node information is a base station identifier and / or a cell identifier, before the terminal device reselects the base station or cell, the terminal device does not monitor paging or initiate an access request. After the terminal device reselects the base station or cell, the terminal device starts monitoring paging or initiating an access request.

[0289] When the second network node information is ephemeris information, the terminal device confirms or predicts the time when the second network node starts providing services based on the ephemeris information and / or the terminal device location information. Before the time for starting to provide services arrives, the terminal device does not monitor paging or initiate an access request. After the time for starting to provide services arrives, the terminal device starts monitoring paging or initiates an access request.

[0290] When the second network node information is the time when the second network node starts to provide services, the terminal device does not monitor paging or initiate an access request before the time when the service starts to be provided arrives, and the terminal device starts to monitor paging or initiate an access request after the time when the service starts to be provided arrives.

[0291] In this embodiment, the interaction process between the terminal device, the first network node, the second network node and the core network device is as follows:

[0293] Optionally, the first network node sends an RRC release message to the terminal device, where the RRC release message carries satellite (base station, such as eNB2) information or time information. The terminal device receives the RRC release message and saves the context information.

[0297] The following describes the process of this embodiment in detail by taking the scenario shown in FIG5 as an example:

[0298] As shown in Figure 5, the first network node is the current serving satellite (eNB1), and the second network node is the next serving satellite (eNB2, eNB3, etc.). The interaction process between the first network node and the terminal device, the core network device, and the second network node is as follows:

[0299] Step 1: The current serving satellite (eNB1) (ie, the first network node) operates in store-and-forward mode (ie, there is no feeder link / S1 connection between eNB1 and the ground station).

[0300] Step 2: The current serving satellite (eNB1) receives and stores the uplink NAS signaling and / or data sent by the terminal device.

[0301] Step 3: The current serving satellite (eNB1) sends an RRC release (radio resource control release) message to the terminal device. The RRC release message carries satellite (base station, such as eNB2) information or time information.

[0302] Optionally, the information carried by the RRC release message indicates the satellite (base station) information that the terminal device (expects) to (attempt) receive / delay receiving downlink NAS signaling and / or data or monitor paging or initiate an access request next time, and / or, the information carried by the RRC release message indicates the satellite (base station) information that carries downlink NAS signaling and / or data, or the terminal device starts monitoring paging or the terminal device initiates an access request, that is, the second network node information.

[0303] Optionally, the information carried in the RRC release message may include at least one satellite information.

[0304] Optionally, the information carried in the RRC release message indicates the time information of the terminal device (expected) next (attempt) to receive downlink NAS signaling and / or data, or monitor paging or initiate an access request.

[0306] Optionally, the satellite information may be at least one of the following: eNB ID, cell ID, satellite ephemeris information, and satellite service start time.

[0307] Optionally, the current serving satellite knows when to restore the feeder link connection with the ground station and send the stored uplink NAS signaling and / or data to the core network device, when there will be downlink feedback signaling and / or data from the core network device, and which satellites will provide services to the terminal device next, so it can be confirmed which satellites can carry the downlink NAS signaling and / or data of the core network device.

[0308] Step 4: The terminal device receives the RRC release message and saves the context information.

[0309] When the information carried by the RRC release message is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information arrives; after the time indicated by the time information arrives, the terminal device starts monitoring paging or initiates an access request.

[0310] Optionally, when the satellite information is an eNB ID or a cell ID, before the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device does not monitor paging or initiate an access request; after the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device starts to monitor paging or initiate an access request.

After the time when the satellite starts providing services arrives, the terminal device starts monitoring paging or initiates an access request.

[0312] Optionally, when the satellite information is the satellite service start time, the terminal device does not monitor paging or initiate an access request before the satellite service start time arrives, and the terminal device starts monitoring paging or initiates an access request after the satellite service start time arrives.

[0313] Step 5: After the current serving satellite (eNB1) and the ground station restore the feeder link / S1 connection, the stored uplink NAS signaling and / or data, satellite information (such as eNB2) / time information, terminal device location information, and terminal device context information are sent to the core network device.

[0314] Step 6: The core network device sends downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information to the next serving satellite (e.g., eNB2), i.e., the second network node, based on the satellite information / time information provided by the current serving satellite (eNB1).

[0315] Step 7: The next satellite providing service (such as eNB2) stores the received downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information, and triggers paging or receives the terminal device's access request after moving to the terminal device location area or the time arrives.

[0316] Through the technical solution of this embodiment, the core network device receives the third information, which is sent by the first network node to the core network device in response to the first condition being met. In the satellite store-and-forward mode, normal interaction between the terminal device, the network device, and / or the core network device can be ensured, allowing services to proceed normally.

[0413] Optionally, the current serving satellite knows when to restore the feeder link connection with the ground station and send the stored uplink NAS signaling and / or data to the core network device, when there will be downlink feedback signaling and / or data from the core network device, and which satellites will provide services to the terminal device next, so it can be confirmed which satellites can carry the downlink NAS signaling and / or data of the core network device.

[0414] Step 4: The terminal device receives the RRC release message and saves the context information.

[0415] When the information carried by the RRC release message is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information arrives; after the time indicated by the time information arrives, the terminal device starts monitoring paging or initiates an access request.

[0416] Optionally, when the satellite information is an eNB ID or a cell ID, before the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device does not monitor paging or initiate an access request; after the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device starts to monitor paging or initiate an access request.

[0422] Through the technical solution of this embodiment, the terminal device performs the first operation based on the first information sent by the first network node.

[0423] Sixth embodiment

[0424] 10 , which is a schematic diagram of an interaction flow between a network device, a terminal device, and a core network device according to a processing method according to a sixth embodiment, the sixth embodiment of the present application proposes a processing method, comprising the steps of:

[0425] S1: The first network node sends first information to the terminal device, so that the terminal device performs a first operation based on the first information;

[0426] S2: The terminal device performs a first operation based on the first information sent by the first network node;

[0427] S10: In response to the first condition being met, the first network node sends third information to the core network device; and

[0428] S3: The core network device receives third information, where the third information is sent by the first network node to the core network device in response to the first condition being met;

[0429] S30: The core network device sends fourth information to the second network node based on the third information;

[0430] S4: The second network node receives fourth information, which is sent by the core network device to the second network node after receiving the third information sent by the first network node. The third information is sent by the first network node to the core network device in response to the first condition being met.

[0431] The solution of this embodiment is mainly applied to scenarios of satellite store-and-forward mode.

[0432] In the satellite store-and-forward mode, network equipment (such as base stations) is deployed on the satellite. When the network equipment (such as base stations) operates in the store-and-forward mode, there is no feeder link connection between the satellite and the ground station.

[0433] Due to satellite movement, the connection between the terminal device and the satellite, and between the satellite and the core network equipment may not exist at the same time. Therefore, the satellite needs to first store the NAS signaling or data from the terminal device or core network equipment, and then send the stored NAS signaling or data to the corresponding network element when the connection is restored.

[0434] Traditional signaling / business processes require network equipment (such as base stations) to send signaling or data to the corresponding network element in a timely manner after receiving it, and the corresponding network element must promptly confirm or respond. Subsequent processes cannot be carried out before receiving confirmation or response from the corresponding network element.

[0435] In the satellite store-and-forward mode, if traditional signaling / service processes are used, it is impossible to ensure normal interaction between terminal devices, network devices and / or core network devices, resulting in the inability to carry out normal services.

[0436] Therefore, this embodiment proposes a signaling / service process to ensure normal interaction between terminal devices, network devices and / or core network devices, so that services can proceed normally. In this embodiment, the network devices include a first network node and / or a second network node.

[0437] Optionally, the first network node operates in a store-and-forward mode, that is, there is no feeder link / S1 connection between the first network node and the ground station.

[0453] When the first information is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information is reached, and the terminal device starts monitoring paging or initiates an access request after the time indicated by the time information is reached;

[0454] When the second network node information is a base station identifier and / or a cell identifier, before the terminal device reselects the base station or cell, the terminal device does not monitor paging or initiate an access request. After the terminal device reselects the base station or cell, the terminal device starts monitoring paging or initiating an access request.

[0455] When the second network node information is ephemeris information, the terminal device confirms or predicts the time when the second network node starts providing services based on the ephemeris information and / or the terminal device location information. Before the time for starting to provide services arrives, the terminal device does not monitor paging or initiate an access request. After the time for starting to provide services arrives, the terminal device starts monitoring paging or initiates an access request.

[0456] When the second network node information is the time when the second network node starts to provide services, the terminal device does not monitor paging or initiate an access request before the time when the service starts to be provided arrives, and the terminal device starts to monitor paging or initiate an access request after the time when the service starts to be provided arrives.

[0457] Optionally, in response to the first condition being met, the first network node sends third information to the core network device, so that the core network device sends fourth information to the second network node.

[0463] Optionally, the next second network node providing service stores the received downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information, and triggers paging or receives an access request from the terminal device after moving to the terminal device location area or the time arrives.

[0464] The following describes the process of this embodiment in detail by taking the scenario shown in FIG5 as an example:

[0465] As shown in Figure 5, the first network node is the current serving satellite (eNB1), and the second network node is the next serving satellite (eNB2, eNB3, etc.). The interaction process between the first network node and the terminal device, the core network device, and the second network node is as follows:

[0466] Step 1: The current serving satellite (eNB1) (ie, the first network node) operates in store-and-forward mode (ie, there is no feeder link / S1 connection between eNB1 and the ground station).

[0467] Step 2: The current serving satellite (eNB1) receives and stores the uplink NAS signaling and / or data sent by the terminal device.

[0468] Step 3: The current serving satellite (eNB1) sends an RRC release (radio resource control release) message to the terminal device. The RRC release message carries satellite (base station, such as eNB2) information or time information.

[0469] Optionally, the information carried by the RRC release message indicates the satellite (base station) information that the terminal device (expects) to (attempt) receive / delay receiving downlink NAS signaling and / or data or monitor paging or initiate an access request next time, and / or, the information carried by the RRC release message indicates the satellite (base station) information that carries downlink NAS signaling and / or data, or the terminal device starts monitoring paging or the terminal device initiates an access request, that is, the second network node information.

[0470] Optionally, the information carried in the RRC release message may include at least one satellite information.

[0471] Optionally, the information carried in the RRC release message indicates the time information of the terminal device (expected) next (attempt) to receive downlink NAS signaling and / or data, or monitor paging or initiate an access request.

[0472] Optionally, the information carried in the RRC release message indicates the time information of carrying downlink NAS signaling and / or data, or when the terminal device starts monitoring paging or initiates an access request.

[0473] Optionally, the satellite information may be at least one of the following: eNB ID, cell ID, satellite ephemeris information, and satellite service start time.

[0474] Optionally, the current serving satellite knows when to restore the feeder link connection with the ground station and send the stored uplink NAS signaling and / or data to the core network device, when there will be downlink feedback signaling and / or data from the core network device, and which satellites will provide services to the terminal device next, so it can be confirmed which satellites can carry the downlink NAS signaling and / or data of the core network device.

[0475] Step 4: The terminal device receives the RRC release message and saves the context information.

[0476] When the information carried by the RRC release message is time information, the terminal device does not monitor paging or initiate an access request before the time indicated by the time information arrives; after the time indicated by the time information arrives, the terminal device starts monitoring paging or initiates an access request.

[0477] Optionally, when the satellite information is an eNB ID or a cell ID, before the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device does not monitor paging or initiate an access request; after the terminal device reselects the eNB (such as eNB2) or the cell, the terminal device starts to monitor paging or initiate an access request.

[0478] Optionally, when the satellite information is ephemeris information, the terminal device confirms or predicts the time when the satellite (such as eNB2) starts to provide services based on the ephemeris information and the terminal device location information. Before the time when the satellite starts to provide services, the terminal device does not monitor paging or the terminal device does not initiate an access request. After the time when the satellite starts providing services arrives, the terminal device starts monitoring paging or initiates an access request.

[0479] Optionally, when the satellite information is the satellite service start time, the terminal device does not monitor paging or initiate an access request before the satellite service start time arrives, and the terminal device starts monitoring paging or initiates an access request after the satellite service start time arrives.

[0480] Step 5: After the current serving satellite (eNB1) and the ground station restore the feeder link / S1 connection, the stored uplink NAS signaling and / or data, satellite information (such as eNB2) / time information, terminal device location information, and terminal device context information are sent to the core network device.

[0481] Step 6: The core network device sends downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information to the next serving satellite (e.g., eNB2), i.e., the second network node, based on the satellite information / time information provided by the current serving satellite (eNB1).

[0482] Step 7: The next satellite providing service (such as eNB2) stores the received downlink NAS signaling and / or data, terminal device location information, time information, and terminal device context information, and triggers paging or receives the terminal device's access request after moving to the terminal device location area or the time arrives.

[0483] Through the technical solution of this embodiment, a first network node sends first information to a terminal device, and the terminal device performs a first operation based on the first information sent by the first network node. In response to satisfying a first condition, the first network node sends third information to a core network device, which receives the third information and, based on the third information, sends fourth information to a second network node, which receives the fourth information. In the satellite store-and-forward mode, normal interaction between the terminal device, network devices, and / or core network devices can be ensured, allowing services to proceed normally.
