[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, the first object can be one or more. Furthermore, "or" in this application indicates at least one of the connected objects. For example, the scope of protection for "A or B" covers at least three scenarios: Scenario 1: including A but not B; Scenario 2: including B but not A; Scenario 3: including both A and B. In addition, the terms "A and / or B," "at least one of A and B," and "at least one of A or B" also cover at least the above three scenarios. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0040] The term "instruction" in this application can be either a direct instruction (or explicit instruction) or an indirect instruction (or implicit instruction). A direct instruction can be understood as one in which the sender explicitly informs the receiver of specific information, the operation to be performed, or the requested result, etc., in the instruction sent. An indirect instruction can be understood as one in which the receiver determines the corresponding information based on the instruction sent by the sender, or makes a judgment and determines the operation to be performed or the requested result, etc., based on the judgment result.

[0041] It is worth noting that the technology described in this application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems, such as Non-Terrestrial Network (NTN) systems, Vehicle-to-Everything (V2X), Internet of Vehicles (IoV), Machine-Type Communications (MTC), Internet of Things (IoT), Machine-to-Machine (M2M), or future mobile communication systems. As a possible application scenario, NTN systems may include satellite systems. Based on their altitude, i.e., their orbital altitude, satellites can be classified into highly elliptical orbit (HEO) satellites, geosynchronous earth orbit (GEO) satellites, medium earth orbit (MEO) satellites, and low earth orbit (LEO) satellites. Furthermore, NTN systems may also include non-terrestrial network equipment (or aerial network equipment) such as high-altitude platform station (HAPS) communication systems. The non-terrestrial network equipment discussed in this application is not limited to the examples mentioned above.

[0042] The terms "system" and "network" used in the embodiments of this application are often used interchangeably, and the described technologies can be used with respect to the systems and radio technologies mentioned above, as well as other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th generation (6G) systems.th Generation 6G communication system.

[0043] To facilitate understanding of the embodiments of this application, the following technical points are introduced first:

[0044] 1. Regarding satellite access in store-and-forward (S&F) mode.

[0045] In NTN communication systems, to achieve data or signaling interaction between terminals and the terrestrial network, it is necessary to ensure that both the service link and the feeder link remain connected simultaneously. However, in some situations, such as the initial deployment of satellite networks where gateway stations are only deployed in certain areas, the simultaneous connection of the service link and feeder link cannot be guaranteed. To support data transmission (e.g., latency-tolerant service data), a store-and-forward communication mode is proposed, such as... Figure 1 As shown. Taking uplink data transmission as an example, when a terminal has uplink data to send, it first sends it to the satellite via the service link (step A), and the satellite stores the relevant data. When the satellite reaches a point where the feeder link is available, it forwards the stored data to the ground network (step B). Similarly, when downlink data needs to be sent to the terminal, the ground network first sends the data to the satellite, and the satellite stores the relevant downlink data. When the satellite reaches a point where the service link is available, it forwards the stored data to the terminal.

[0046] In related technologies, when a terminal receives a rejection message from the network, it may start a wait timer. During the wait timer's operation, the terminal will not initiate a service request to the network. If the wait timer is not set appropriately, it may prevent the terminal from obtaining network services quickly. Alternatively, during the period when the terminal does not initiate a service request, it may still perform unnecessary actions such as signal measurement or network search, wasting the terminal's power consumption.

[0047] Question 1: If the terminal receives the first time value and starts the waiting timer, it does not perform the Non-Access Stratum (NAS) procedure in the current network during the running of the waiting timer. The existing technology only specifies that the terminal does not initiate signaling. How the terminal performs signal measurement in order to perform cell selection or reselection needs to be specified.

[0048] Question 2: If the terminal does not receive the initial time value, its behavior is unregulated. For example, the terminal might frequently retry. In this case, it's necessary to regulate how to help the terminal conserve energy. Furthermore, the terminal might start an inappropriate timer. In this situation, it's necessary to regulate how to help the terminal obtain network services as quickly as possible.

[0049] As an example, Figure 2 This diagram illustrates an architecture of an NTN network to which embodiments of this application can be applied. The NTN network includes terminals and network-side equipment.

The term "base station" is not limited to any specific technical terminology. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

If the name of the core network equipment mentioned in this application embodiment changes in subsequent protocol versions (e.g., 6G), it will still be within the scope of protection of this application.

[0053] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this.

[0060] In one embodiment, before the terminal performs a first operation based on the first information, the method further includes: the terminal acquiring the first information.

[0061] For example, the terminal receives first information sent by a first network device or other network devices.

[0062] Optionally, in one implementation, if the terminal supports store-and-forward mode or store-and-forward satellite service and the first network device is in store-and-forward mode, then the first network device sends first information to the terminal. In one embodiment of this application, the first message includes at least one of the following:

[0063] 1) First information;

[0064] Specifically, if the terminal locally stores the first information, the first information may be included in the first message sent by the terminal in the first process for synchronizing the first information with the first network device. Furthermore, the first network device considers the first information provided by the terminal when determining the first information to be provided to the terminal in the response message of the first message.

[0065] 2) Second information, which is used to indicate whether the terminal supports store-and-forward mode (S&F mode) or store-and-forward satellite service (S&F satellite service);

[0066] For example, the second information can be a 1-bit indication. If the terminal supports store-and-forward mode and requests to use store-and-forward mode, this 1-bit indication can be set to "1", indicating that the terminal supports store-and-forward mode or store-and-forward satellite service. Optionally, the second information can also be called the UE networkcapability information element (UE networkcapability IE).

[0067] 2) Third information, which indicates that the first process is the process by which the terminal performs store-and-forward satellite services.

[0068] For example, when a terminal initiates an attach procedure for store-and-forward satellite service, the terminal can indicate through third information that the first procedure is a process in which the terminal performs store-and-forward satellite service. Optionally, the third information can also be indication information in the EPS attach type information element (IE), such as bit "111" in the EPS attach type value used to indicate S&F mode.

[0069] In one embodiment of this application, the first information includes at least one of the following:

[0070] 1) First rejection reason value, which indicates the reason why the first message was rejected by the first network device;

[0071] Optionally, the reasons indicated by the first rejection reason value include at least one of the following: a) the first network device does not provide continuous coverage for the first process; b) the terminal is not within the coverage area of ​​the first network device; c) the first network device lacks information about the terminal, such as the missing terminal information may include, but is not limited to, the terminal's authentication vector or the terminal's subscription information and other necessary terminal information; d) the first network device lacks store-and-forward mode; e) the first network device provides store-and-forward satellite service.

[0072] Optionally, the reason indicated by the first rejection reason value may also include at least one of the following: the terminal is not allowed to use the PLMN, the requested service option is not authorized in this PLMN, the terminal is not allowed to use EPS services in this PLMN, the service network has failed, or the PLMN is not allowed to operate at the present UE location. The first communication device belongs to the PLMN.

[0073] 2) A first time value, wherein the first time value is used to indicate at least one of the following: the waiting time for the terminal to retry the first process, and the start time of the terminal retrying the first process;

[0074] Optionally, the first time value is used to indicate the minimum time or duration that the terminal needs to wait before retrying the first process within the current PLMN. Optionally, the first time value is determined based on the time when the terminal will next be able to be served by network devices (e.g., satellites).

[0075] Optionally, the first time value is encoded as a first information element, the first information element including an information element identifier, the length of the first time value, and a content field of the first time value, such as... Figure 6 As shown.

[0076] Optionally, the content field of the first time value can be a subset of at least one of the following: a time duration information element (IE), a first General Packet Radio Service (GPRS) timer information element, a second GPRS timer information element, and a third GPRS timer information element. Specifically, the content field can be 3 to 5 bytes of the time duration information element.

[0077] Optionally, the first time value may also be a component of an existing information element, such as the unavailability period duration or the start of the unavailability period duration.

[0078] Optionally, the first network device considers a first time value when determining the mobile reachability timer and the implicit detach timer.

[0079] Optionally, the first network device determines the first time value based on at least one of the following: ephemeris information, first information received from the terminal, information configured on the first network device, and operator policy information.

[0080] 3) A first identifier, which is used to indicate a target network device, and the terminal retryes the first process with the target network device under the current network.

[0081] Optionally, the first identifier can be a first list including the identifiers of one or more target devices, such as a store-and-forward monitoring list (S&F monitoring list), under the current network, the terminal can retry the first process to one or more target devices.

[0082] Optionally, the first identifier is encoded as a second information element, the second information element comprising at least one of the following: an information element identifier, the length of the first identifier, and a content field of the first identifier, the content field including identifiers of one or more target network devices, such as... Figure 7 As shown. Optionally, the identifier of the target network device can be a binary or hexadecimal encoded integer.

[0083] 4) First location information, the first location information being used to instruct the terminal to retry the first process.

[0084] Optionally, the first location information can be at least one of the following: one or more geographic location information, one or more tracking area information, or one or more cell identification information.

[0085] In one embodiment of this application, when the first information satisfies a first condition, the terminal performs a second operation, including:

[0086] If the first information contains a first rejection reason value, the terminal performs a cell or network selection operation based on the first rejection reason value.

[0087] Specifically, if the terminal does not contain the second or third information in the first message, the first network device includes a first rejection reason value in the response message of the first message, indicating that the PLMN to which the first communication device belongs is not allowed to operate at the current location of the terminal, and does not include a first time value and a first identifier. The terminal not containing the second information in the first message includes: the terminal not including the second information or the terminal setting the second information to indicate that the terminal does not support store-and-forward mode or store-and-forward satellite service.

[0088] The terminal does not contain third information in the first message, including: the terminal does not include third information or the terminal sets the attachment type to at least one of the following: EPS attach, combined EPS / IMSI attach, EPS RLOS attach, EPS emergency attach.

[0089] When the terminal receives the first rejection reason value, in addition to performing cell or network selection, it may also perform at least one of the following: set the EPS update status to EU3 ROAMING NOT ALLOWED, delete any Globally Unique Temporary UE Identity (GUTI), the last visited Tracking Area Identity (TAI), TAI list or Evolved Key Set Identifier (eKSI), reset the registration attempt counter, store the current PLMN identifier and current geographic location in the "PLMNs not allowed to run at the current terminal location" list, and start the corresponding timer instance.

[0090] In one embodiment of this application, when the first information satisfies a first condition, the terminal performs a first operation based on the first information, including one of the following:

[0091] 1) When the first information satisfies the first condition and the terminal satisfies the second condition, the terminal performs the first operation based on the first information;

[0092] Wherein, the first information satisfies the first condition including: the first information contains a first time value, and the terminal satisfies the second condition including: the terminal is configured with a third time value, the third time value being used to indicate the waiting time for the terminal to retry the first process.

[0093] 2) If the first information satisfies the first condition and the terminal does not satisfy the second condition, the terminal performs a power-saving operation based on the first information;

[0094] In one embodiment of this application, when the first information satisfies a first condition and the terminal satisfies a second condition, the terminal performs a first operation based on the first information, including one of the following:

[0095] 1) If the first information contains a first time value and the first time value is greater than the third time value, the terminal performs a cell or network selection operation based on the first information;

[0096] In this embodiment, if the terminal receives a first time value and the received first time value is greater than the third time value, it indicates that the time value provided by the network to the terminal is unreliable or unreasonable (considering that the network deployed on the first communication device (e.g., satellite) may lack UE information or the information may not be updated in time). At this time, the terminal starts a timer with a reasonable time value (the third time value). After the timer expires, the terminal can obtain network services as soon as possible.

[0097] 2) If the first information contains a first time value and the first time value is less than or equal to the third time value, the terminal performs a power-saving operation based on the first information.

[0098] In this embodiment, if the terminal receives a first time value that is less than or equal to the third time value, it indicates that the time value provided by the network to the terminal is reliable or reasonable. At this time, the terminal starts a first timer with the third time value, and during the operation of the first timer, the terminal does not initiate any service requests to the network. Furthermore, by performing power-saving operations, the terminal can avoid performing unnecessary operations, such as signal measurement or network searching, thereby further reducing terminal power consumption.

[0099] In one embodiment of this application, if the first information does not meet the first condition, the terminal performs a second operation, including one of the following:

[0100] 1) If the first information does not contain a first time value and the terminal meets the third condition, the terminal performs a power-saving operation;

[0101] The third condition for the terminal to meet includes: the terminal is configured with a fourth time value, which is used to indicate the waiting time for the terminal to retry the first process.

[0102] In this embodiment, the terminal does not receive the first time value. The terminal performs a power-saving operation based on the configured fourth time value. It can start the first timer at a reasonable time value. During the operation of the first timer, the terminal will not resend the first process to the network, which can save the terminal's energy consumption.

[0103] 2) If the first information does not contain a first time value and the terminal does not meet the third condition, the terminal performs a cell or network selection operation;

[0104] In this embodiment, the terminal does not receive the first time value, nor does it configure the fourth time value. The terminal performs cell or network selection based on the information stored in its memory or the information configured. It can start the first timer with a random and short time value. When the first timer expires, the terminal can select a satellite or terrestrial network that can provide services as soon as possible in order to obtain network services as quickly as possible.

[0105] In one embodiment of this application, performing a power-saving operation includes at least one of the following:

[0106] 1) Deactivate the access layer;

[0107] 2) Activate the first mode, which is used to save power;

[0108] Optionally, the first mode includes at least one of the following: store-and-forward mode, unavailability period mode, Mobile Initiated Connection Only (MICO) mode, and Power Save Mode (PSM).

[0109] 3) Control time for PLMN periodic attempts without stopping;

[0110] In one implementation, when the network is unavailable due to store-and-forward satellite services, the terminal can deactivate the access layer to save power. However, the terminal can still perform periodic network selection to obtain network services as quickly as possible. Optionally, the terminal can implement periodic network selection by not stopping the control time of the PLMN periodic attempts. When the control time of the PLMN periodic attempts expires, the access layer is reactivated (either by the NAS layer providing an indication or request to the access layer, or by an implementation-dependent method). Here, the control time of the PLMN periodic attempts can be timerT.

[0157] Optionally, the UE replaces the stored first time value and first identifier with the received seventh time value and third identifier.

[0158] In one embodiment of this application, after the terminal receives the third message sent by the second network device, when the terminal is in an idle state and there is uplink data transmission required, the method further includes:

[0159] The terminal sends a fourth message to the third network device and starts a second timer associated with the fourth message, which is used to carry uplink data.

[0166] In one embodiment of this application, the method further includes at least one of the following:

[0167] 1) If the fifth message is received before the second timer expires, the terminal determines that the data transmission was successful.

[0168] 2) If the terminal is in store-and-forward mode when the second timer expires, and the terminal does not receive the rejection message of the fourth message, then the terminal determines that the data transmission was successful.

[0169] Optionally, the fifth message includes at least one of the following:

[0170] 1) The eighth time value, which is used to indicate the waiting time for the terminal to retry the first process.

[0171] 2) Fourth identifier;

[0173] 3) The ninth time value is used to indicate the data uplink transmission time.

[0174] Optionally, the ninth time value can be the estimated UL delivery time.

[0175] In this embodiment, without changing the behavior on the network side, the terminal can determine whether the data transmission is successful by adding a second timer.

[0176] In this embodiment of the application, when the terminal determines that its first message has been rejected based on the first information, the terminal can flexibly choose the corresponding operation according to whether the first information meets the first condition. Specifically, if the first information meets the first condition, the terminal performs the first operation based on the first information; or if the first information does not meet the first condition, the terminal performs the second operation. The first operation and the second operation both include at least one of the following: power saving operation, cell or network selection operation. This information processing method can reduce unnecessary operations of the terminal, thereby reducing terminal energy consumption or enabling the terminal to take network selection in a timely manner to obtain network services as soon as possible.

[0177] See Figure 4 This application provides an information processing method applied to a first network device, such as a first satellite or a first non-terrestrial network device, the specific steps of which include:

[0178] Step 41: The first network device receives a first message sent by the terminal, the first message being used to request the first process;

[0179] Step 42: The first network device sends first information to the terminal, the first information being used to indicate that the first message sent by the terminal is rejected by the first network device.

[0180] In one embodiment of this application, the first information includes at least one of the following:

[0181] The first rejection reason value is used to indicate the reason why the first message was rejected by the first network device.

[0182] A first time value, the first time value being used to indicate at least one of the following: the waiting time for the terminal to retry the first process, the start time of the terminal retrying the first process;

[0183] A first identifier is used to indicate a target network device, and the terminal retryes the first process with the target network device under the current network.

[0184] First location information, which is used to indicate the location information of the terminal to retry the first process.

[0185] In one embodiment of this application, the reason indicated by the first rejection reason value includes at least one of the following:

[0186] 1) The first network device provides discontinuous coverage;

[0187] 2) The terminal is not within the coverage area of ​​the first network device;

[0188] 3) The first network device lacks information about the terminal;

[0189] 4) The first network device is in store-and-forward mode;

[0190] 5) The first network device provides store-and-forward satellite services;

[0191] 6) The PLMN to which the first network device belongs is not allowed to operate at the current location of the terminal.

[0192] In one embodiment of this application, the first time value is determined based on the time when the terminal will be able to receive services from the network device next time.

[0193] In this embodiment, a first network device sends first information to a terminal. The first information indicates that a first message sent by the terminal is rejected by the first network device. When the terminal determines that its first message has been rejected based on the first information, the terminal can flexibly choose the corresponding operation based on whether the first information meets a first condition. Specifically, if the first information meets the first condition, the terminal performs a first operation based on the first information; or if the first information does not meet the first condition, the terminal performs a second operation. Both the first and second operations include at least one of the following: a power-saving operation, or a cell or network selection operation. This information processing method can reduce unnecessary operations of the terminal, thereby reducing terminal power consumption or enabling the terminal to take timely network selection to obtain network services as soon as possible.

[0194] Example 1:

[0195] See Figure 5 The specific steps are as follows:

[0196] Step 1: The UE sends a first message to a first network device (e.g., a first satellite). The first message is used to initiate a first procedure, which is used for at least one of the following: obtaining network services, indicating unavailable time or a change in unavailable time to the first network device, and performing EPS service or store-and-forward satellite service procedures.

[0197] Optionally, the first process includes, but is not limited to, at least one of the following: initial registration process, mobility registration update process, deregistration process, UE configuration update process, PDU session establishment process, attach process, TAU process, CP service request process, and service request process.

[0198] Optionally, the first message contains at least one of the following:

[0199] 1) First information;

[0200] If the UE locally stores the first information, the first message sent by the UE in the first process may contain the first information for synchronizing the first information with the first network device.

[0201] 2) The second piece of information is used to indicate whether the UE supports S&F mode or S&F satellite service;

[0202] 3) The third piece of information is used to indicate the process by which the first process is used by the terminal to perform store-and-forward satellite services;

[0203] Step 2: The first network device sends first information to the UE. The first information is used to indicate that the first message sent by the terminal is rejected by the first network device. For example, the first information is used to indicate that the first process is rejected due to discontinuous coverage, lack of coverage, lack of necessary UE information, or forwarding satellite mode.

[0204] Optionally, the first information includes at least one of the following:

[0205] 1) First rejection reason value, which indicates the reason why the first message was rejected by the first network device (i.e., the reason why the first process was rejected);

[0206] For example, the reasons include, but are not limited to, at least one of the following: the first process is rejected because the first communication device does not provide discontinuous coverage for the first process; the first process is rejected because the terminal lacks coverage from the first network device; the first process is rejected because the first network device lacks necessary UE information; the first process is rejected because the first network device lacks store-and-forward satellite mode. It should be noted that the reasons why the first message is rejected by the first network device can be divided into first reasons and second reasons.

[0207] For example, the first reason includes, but is not limited to, at least one of the following: the first network device does not provide continuous coverage for the first process; the terminal is not within the coverage area of ​​the first network device; the first network device lacks necessary terminal information; the first network device lacks store-and-forward mode; the first network device may set the EMM cause value to #xx"first rejection cause value", such as store-and-forward satellite service or store-and-forward satellite operation (S&F Satellite operation), and may assign a first time value, which may be an existing unavailability period duration or a new time value, such as store-and-forward satellite service retry wait time.

[0208] For example, the second cause includes, but is not limited to, the provision of store-and-forward satellite services by the first network device. The first network device may set the EMM cause value to #22 "congestion" and may assign a first time value (e.g., a back-off timer T3346). Optionally, the first time value may be determined based on the time when the UE may be served by the satellite next time. For example, the first time value may be configured as the remaining time of a running access attempt timer or access timer (e.g., T3447).

[0209] It is worth noting that the second reason may also include at least one of the following: the terminal is not allowed to use the PLMN, the service option requested by the terminal in the PLMN is not authorized, the terminal is not allowed to use the EPS service in the PLMN, the service network has failed, or the PLMN is not allowed to run at the terminal's current location.

[0210] 2) First time value, used to indicate the waiting time before retrying the first process. For example, the first time value can be the minimum time value to wait before retrying the first process.

[0211] See Figure 6 The first time value is encoded as a first information element, and the information element containing the first time value includes at least one of the following: an information element identifier, the length of the first time value, and a content field of the first identifier.

[0212] Optionally, the content field of the first time value can be a subset of at least one of the following: a time duration information element (IE), a first General Packet Radio Service (GPRS) timer information element, a second GPRS timer information element, and a third GPRS timer information element. Specifically, the content field can be 3 to 5 bytes of the time duration information element.

[0213] For example, when the EMM cause value is set to #xx "first rejection cause value", the first network device may include this IE to provide a minimum wait timer value for any entry which is in the list of "S&F Monitoring List".

[0214] Optionally, the first time value mentioned above can also be an existing time value, such as backoff timer T3346, or unavailability period duration.

[0215] 3) First identifier, used to indicate the target network device on which the terminal can retry the first process under the current network.

[0216] Optionally, the first identifier can be a first list including the identifiers of one or more target devices, such as a store-and-forward monitoring list, and the terminal can retry the first process with one or more target devices under the current network.

[0217] See Figure 7 The first identifier is encoded as a second information element, which includes at least one of the following: an information element identifier, the length of the first identifier, and a content field of the first identifier, wherein the content field includes the identifiers of one or more target network devices.

[0218] Optionally, the identifier of the target network device can be a binary or hexadecimal encoded integer, which can be 2 bytes (with values ​​of 0, ..., 255) or 3 bytes (0, ..., 65535).

[0219] In one implementation, if the UE supports store-and-forward mode or store-and-forward satellite service and the first network device is in store-and-forward mode, the first network device sends first information to the UE.

[0220] Step 3: The UE receives first information. If the first information satisfies the first condition, the terminal performs a first operation based on the first information. The first operation includes at least one of the following: a power saving operation, a cell or network selection operation; or, if the first information does not satisfy the first condition, the terminal performs a second operation. The second operation includes at least one of the following: a power saving operation, a cell or network selection operation.

[0221] Optionally, performing power-saving operations includes at least one of the following:

[0222] a) Deactivate the access layer;

[0223] b) Activate the first mode, which is used to save power;

[0224] Optionally, the first mode includes at least one of the following: store-and-forward mode, unavailability period mode, MICO-only mode, and PSM.

[0225] Furthermore, after the first mode is activated, all Non-Access Stratum (NAS) timers are stopped and associated processes are terminated, with the exception of a few NAS timers and processes.

[0226] c) Control time T without stopping the PLMN's periodic attempts;

[0227] d) Delay one or more periodic attempts to perform a web search;

[0228] e) Store the parameters carried by the first message that was previously rejected;

[0229] g) Entering a first state, where the terminal is performing a power-saving operation.

[0230] Optionally, the first state includes at least one of the following:

[0231] a) EMM-DEREGISTERED.ATTEMPTING-TO-ATTACH;

[0232] b)EMM-DEREGISTERED.NO-CELL-AVAILABLE;

[0233] c)EMM-REGISTERED.ATTEMPTING-TO-ATTACH;

[0234] d)EMM-REGISTERED.NO-CELL-AVAILABLE.

[0235] 7) Start the first timer. During the execution of the first timer, the terminal cannot retry the first process on the current network;

[0236] In one implementation, the first information includes a first time value. The UE starts a first timer based on the first time value or a default time range. During the execution of the first timer, the UE cannot retry a previously rejected first procedure on the current network.

[0237] Optionally, the first process is integrity protected, in which the UE starts a first timer using a first time value.

[0238] Optionally, the first process is not integrity protected. The UE randomly selects a time value within a default time range (as agreed upon in the protocol, for example, a default time range of 2 to 3 hours) as the fifth time value, and starts the first timer based on the fifth time value.

[0239] f) Abandon the first process;

[0240] g) Associate the current first network device identifier with the current PLMN to re-initiate the previously rejected first process to the network;

[0241] Optionally, the second identifier can be a second list including the identifiers of one or more target devices, such as a store-and-forward monitoring list, which allows the terminal to retry the first process with one or more target devices under the current network.

[0242] If the first network device lacks UE information, the first information sent to the UE may be unreliable or unreasonable. In this embodiment, the UE retry behavior when the first process is rejected by the first network device can be controlled by configuring a third or fourth time value for the UE. Optionally, the third or fourth time value represents the UE retry waiting time or maximum waiting time configured under the Store & Forward Satellite Service (S&Fsatellite service). Optionally, the waiting time or maximum waiting time can be 2 hours.

[0243] Furthermore, if the first message is rejected by the first network device, the reason value can be the reason value #22, #xx (first reason value) specified in the related technologies.

[0244] In one implementation, if the first information includes a first time value, and the first time value is less than or equal to the third time value, the terminal performs a power-saving operation based on the first information. Specifically, if the first time value received by the UE is not greater than the configured third time value, it indicates that the first information provided by the first network device is reasonable, and therefore the UE performs a power-saving operation.

[0245] In one implementation, if the first information includes a first time value and the first time value is greater than the third time value, the terminal performs a cell or network selection operation based on the first information. Specifically, if the first time value received by the UE is greater than the configured third time value, the UE performs a cell or network selection operation.

[0246] Optionally, the operation of performing cell or network selection includes at least one of the following:

[0247] a) Perform cell or network (i.e., PLMN) selection;

[0248] b) When performing cell or network selection, do not select the first network device or the current network;

[0249] Optionally, the current network can be added to the Store & Forward Satellite Service (S&F) prohibited PLMN list, or the identifier of the current first network device can be added to the Store & Forward Satellite Service prohibited network device list.

[0250] c) Abandon the first process;

[0251] d) Entering the second state;

[0252] e) Retry the first process in the selected cell or network.

[0253] In one implementation, if the first information does not contain a first time value and the terminal meets a third condition, the terminal performs a power-saving operation; or, if the first information does not contain a first time value and the terminal does not meet the third condition, the terminal performs a cell or network selection operation.

[0254] The third condition for the terminal to meet includes: the terminal is configured with a fourth time value, which is used to indicate the waiting time for the terminal to retry the first process.

[0255] In one implementation, if the UE is configured with a fourth time value when the first information does not include a first time value, the UE starts a first timer using the configured fourth time value. During the operation of the first timer, the UE cannot retry the previously rejected first process on the current network, and the UE performs a power-saving operation.

[0256] In one implementation, if the first information does not include a first time value, and the UE has not configured a fourth time value, then the UE performs at least one of the following:

[0257] a) The UE starts a first timer using an existing time value (e.g., T3441, T3346) or a random time value. During the operation of the first timer, the UE cannot retry the previously rejected first procedure on the current network, and the UE performs a first operation to assist the UE in saving energy.

[0258] b) The UE performs a cell or network selection operation.

[0259] Step 4: The first network device synchronizes the acquired UE information and the first message with the terrestrial network. The terrestrial network then provides the necessary UE information (e.g., authentication vector or subscription information) to the next satellite network device that can provide services to the UE.

[0260] Step 5: When the first timer times out and the UE receives the identifier of the second network device from the broadcast information, the identifier of the second network device is in the stored first identifier, the UE sends a second message to the second network device. The second message is used to re-initiate the previously incomplete first process, and the content of the second message is the same as the content of the first message.

[0261] Step 6: The second network device sends a third message to the UE, the third message being used to indicate acceptance of the second message.

[0262] Optionally, the third message includes at least one of the following:

[0263] a) A seventh time value, which is used to indicate the waiting time for the terminal to retry the first process;

[0264] b) Third identifier;

[0265] Optionally, the third identifier can be a third list that includes the identifiers of one or more target devices, such as a store-and-forward monitoring list, which allows the terminal to retry the first process with one or more target devices under the current network.

[0266] c) The eighth time value is used to indicate the data uplink transmission time;

[0267] Optionally, the data uplink transmission time can be the time it takes for data to be transmitted from the terminal to the terrestrial network, or it can be the time it takes for data to be transmitted from a non-terrestrial network device to the terrestrial network.

[0268] Optionally, the eighth time value can be the estimated UL delivery time.

[0269] Optionally, the UE replaces the stored first time value and first identifier with the received seventh time value and third identifier.

[0270] The purpose of providing the seventh time value and the third identifier again in the third message is to update the UE-related information in a timely manner. After communicating with the terrestrial network, the second network device may obtain the changed UE-related information, so it synchronizes with the UE.

[0271] Step 7: When the UE is in an idle state and has uplink data to transmit, the UE sends a fourth message to the third network and starts the second timer associated with the fourth message. The fourth message is used to carry uplink data.

[0272] Optionally, the fourth message can be a Control Plane Service Request (CP service request) message, and the second timer can be T3417. For example, the default value of T3417 is 5 seconds. In narrowband mode, the value of T3417 is 5 + 240 = 245 seconds.

[0273] Optionally, if the UE is in store-and-forward mode and receives a sixth time value (e.g., estimated UL delivery time or estimated DL delivery time), the UE uses the received sixth time value to set a second timer, the value of which is not less than the sixth time value.

[0274] Step 8: If the third network device lacks the necessary information for the UE, it will directly reject the UE's fourth message, as in Step 2. However, if the third network device stores the necessary information for the UE, it will accept the fourth message, including the following two options:

[0275] Step 8a: If the signaling interface (e.g., S11-U) connection between the user plane and control plane in the core network architecture is not established and the third network device is in store-and-forward mode, the third network device directly sends the fourth message acceptance message to the UE.

[0276] According to existing technology, if the signaling interface (S11-U) between the user plane and control plane in the core network architecture is not established, the MME will trigger an establishment procedure. After establishment, the MME forwards the data to the SGW, and then the MME sends a fourth message acceptance message to the UE. To ensure successful data transmission without modifying UE behavior, network behavior needs to be enhanced.

[0277] Step 8b: The third network device will send the fourth message acceptance message to the UE after forwarding the data to the SGW. This means that the third network device sends the fourth message acceptance message to the UE after interacting with the terrestrial network.

[0278] If the UE starts the second timer with the existing value in step 7, the UE may not receive the acceptance message for the fourth message after the second timer expires. The UE will then consider the transmission of the fourth message to have failed, i.e., the data transmission has failed.

[0279] Step 9: Optionally, the third network device sends a fifth message to the UE, which is used to indicate acceptance of the fourth message.

[0280] Optionally, the fifth message includes at least one of the following:

[0281] 1) The eighth time value, which is used to indicate the waiting time for the terminal to retry the first process.

[0282] 2) Fourth identifier;

[0283] Optionally, the fourth identifier can be a fourth list that includes the identifiers of one or more target devices, such as a store-and-forward monitoring list (S&F monitoring list), which allows the terminal to retry the first process with one or more target devices under the current network.

[0284] 3) The ninth time value is used to indicate the data uplink transmission time.

[0285] Optionally, the ninth time value can be the estimated UL delivery time.

[0286] Step 10: The UE determines that the data transmission was successful if at least one of the following conditions is met:

[0287] 1) The UE receives the fifth message before the second timer expires.
