[0043] It is worth noting that the technology described in the embodiments of the present application is not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, and 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, for example, Non Terrestrial Network (NTN) systems, vehicle to everything (V2X), Internet of Vehicles, machine type communications (MTC), Internet of Things (IoT), machine to machine (M2M), or future mobile communication systems. As a possible application scenario, the NTN system can include a satellite system. According to the satellite altitude, i.e. the satellite orbit altitude, the satellite can be divided into highly elliptical orbit (HEO) satellite, geosynchronous earth orbit (GEO) satellite, medium earth orbit (MEO) satellite and low earth orbit (LEO) satellite. In addition, the NTN system can also include non-ground network equipment (or referred to as aerial network equipment) such as high altitude platform station (HAPS) communication system, and the non-ground network equipment involved in the present application is not limited to the above examples.

[0044] The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used in the above-mentioned systems and radio technologies, and also in other systems and radio technologies. The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to systems other than NR systems, such as 6th Generation, 6G) communication system.

[0045] In order to facilitate the understanding of the embodiments of the present application, the following technical points are introduced first:

[0046] 1. About satellite access in store and forward (S&F) mode.

[0047] In the NTN communication system, in order to realize the data or signaling interaction between the terminal and the ground network, it is necessary to ensure that the service link and the feeder link can be connected at the same time. However, in some cases, such as the initial deployment of the satellite network, the gateway station is only deployed in some areas, and it cannot be ensured that the service link and the feeder link can be connected at the same time. In order to support data transmission (such as delay-tolerant service data), a store and forward communication mode is proposed, as shown in FIG. 1. Taking uplink data transmission as an example, when the terminal has uplink data to send, it can first send the data to the satellite through the service link (step A), and the satellite stores the relevant data. When the satellite runs to the feeder link available, the stored data is forwarded to the ground network (step B). Similarly, when there is downlink data 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 runs to the service link available, the stored data is forwarded to the terminal.

[0048] In the related art, when the terminal receives the rejection message sent by the network, the terminal can start a wait timer. During the running of the wait timer, the terminal does not initiate a service request to the network. If the wait timer is not set reasonably, the terminal cannot obtain network services as soon as possible. Or during the period when the terminal does not initiate a service request, the terminal still performs unnecessary behaviors such as signal measurement or network search, which wastes the terminal energy consumption.

[0049] Problem 1: If the terminal receives the first time value and starts the wait timer, the terminal does not perform the non-access stratum (NAS) procedure in the current network during the running of the wait timer. The related art only specifies that the terminal does not initiate signaling, and how the terminal performs signal measurement for cell selection or reselection needs to be specified.

[0050] Problem 2: If the terminal does not receive the first time value, the behavior of the terminal is not specified. For example, the terminal can frequently retry. In this case, how to assist the terminal to save energy needs to be specified. In addition, the terminal can start an inappropriate timer. In this case, how to assist the terminal to obtain network services as soon as possible needs to be specified.

The first operation and the second operation both include at least one of the following: an operation for saving power, an operation for cell or network selection. This information processing manner can reduce unnecessary operations of the terminal, thereby reducing the power consumption of the terminal or enabling the terminal to take network selection in time to obtain network service as soon as possible.

[0197] Embodiment One:

[0198] Referring to FIG. 5, the specific steps are as follows:

[0199] Step 1: The UE sends a first message to the first network device (for example, a first satellite), the first message being used to initiate a first process, the first process being used for at least one of the following: obtaining network service, indicating an unavailable time or a change in the unavailable time to the first network device, and being used for the terminal to perform an EPS service or a store-and-forward satellite service process.

[0200] Optionally, the first process includes but is not limited to at least one of the following: an initial registration process, a mobility registration update process, a deregistration process, a UE configuration update process, a PDU session establishment process, an attach process, a TAU process, a CP service request process, and a service request process.

[0201] Optionally, the first message contains at least one of the following:

[0202] 1) first information;

[0203] If the UE has the first information locally stored, the UE can include the first information in the first message sent in the first procedure for synchronizing the first information with the first network device.

[0204] 2) second information for indicating that the UE supports S&F mode or S&F satellite service;

[0205] 3) third information for indicating that the first procedure is for the terminal to perform a procedure of storing and forwarding satellite service;

[0206] 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 procedure is rejected due to discontinuous coverage, lack of coverage, lack of necessary UE information or forwarding satellite mode.

[0207] Optionally, the first information includes at least one of the following:

[0208] 1) first rejection reason value for indicating the reason for which the first message is rejected by the first network device (i.e. the reason for which the first procedure is rejected);

[0209] For example, the reason includes but is not limited to at least one of the following: the first procedure is rejected due to the fact that the first communication device does not provide discontinuous coverage for the first procedure, the first procedure is rejected due to the fact that the terminal lacks coverage of the first network device, the first procedure is rejected due to the fact that the first network device lacks necessary UE information, the first procedure is rejected due to the fact that the first network device lacks storing and forwarding satellite mode. It should be noted that the reason for which the first message is rejected by the first network device can be divided into a first reason and a second reason.

[0210] 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 procedure, the terminal is not within the coverage of the first network device, the first network device lacks necessary terminal information, the first network device lacks storing and forwarding mode, the first network device can set an EMM cause value (cause value) as "#xx first rejection reason value", for example, storing and forwarding satellite service or storing and forwarding satellite operation (S&F Satellite operation), and can assign a first time value, the first time value can be an existing unavailability period duration or a new time value, for example, storing and forwarding satellite service retry wait time (S&F satellite service Retry wait time).

[0211] For example, the second cause includes, but is not limited to, the first network device providing store-and-forward satellite service, the first network device can set the EMM cause value to #22 "congestion", and can assign a first time value (e.g., back-off timer T3346). Optionally, the first time value can be determined according to the next time when the UE can be served by a satellite, for example, the first time value can be configured as the remaining time of an ongoing access attempt timer or access timer (e.g., T3447).

[0212] It is worth mentioning that the second cause can further include at least one of the following: the terminal is not allowed to use the PLMN, the service option requested by the terminal is not authorized in the PLMN, the terminal is not allowed to use the EPS service in the PLMN, the service network fails, and the PLMN is not allowed to operate in the current location of the terminal.

[0213] 2) The first time value, used to indicate the waiting time for reattempting the first procedure, for example, the first time value can be the minimum time value to wait before reattempting the first procedure.

[0214] Referring to FIG. 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: information element identification, length of the first time value, and content field of the first identification.

[0215] Optionally, the content field of the first time value can be part of at least one of the following: time duration information element (Time duration IE), first general packet radio service (GPRS) timer information element, second GPRS timer information element, and third GPRS timer information element. Specifically, the content field can be 3 to 5 bytes of the time duration information element.

[0216] For example, when the EMM cause value is set to #xx "first rejection cause value", the first network device can include a first information element of the first time value, so as to provide a minimum wait timer value for any entry in the list of the S&F Monitoring List.

[0217] Optionally, the first time value can also be an existing time value, such as the back-off timer T3346 or the unavailability period duration.

[0218] 3) The first identifier, used to indicate the target network device to which the terminal can re-attempt the first procedure under the current network.

[0219] Optionally, the first identifier can be a first list including the identifier of one or more target devices, such as the S&F Monitoring List, to which the terminal can re-attempt the first procedure under the current network.

[0220] Referring to FIG. 7, the first identifier is encoded into a second information element, and the second information element 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 identifier of one or more target network devices.

[0221] Optionally, the identifier of the target network device can be a binary or hexadecimal coded integer, which can be 2 bytes (value 0,..., 255) or 3 bytes (0,..., 65535).

[0222] In an embodiment, if the UE supports the store-and-forward mode or the store-and-forward satellite service and the first network device is in the store-and-forward mode, the first network device sends the first information to the UE.

[0223] Step 3: The UE receives the first information, and in the case that the first information satisfies the first condition, the terminal performs a first operation according to the first information, and the first operation includes at least one of the following: power saving operation, cell or network selection operation; or in the case that the first information does not satisfy the first condition, the terminal performs a second operation, and the second operation includes at least one of the following: power saving operation, cell or network selection operation.

[0224] Optionally, the power saving operation comprises at least one of:

[0225] a) deactivating the access stratum;

[0226] b) activating a first mode, the first mode being for saving power;

[0227] Optionally, the first mode comprises at least one of: store-and-forward mode, unavailability period mode, MICO only mode, PSM.

[0228] Further, after the first mode is activated, all Non-Access Stratum (NAS) timers are stopped and associated procedures are terminated, except for some exceptional NAS timers and procedures.

[0229] c) not stopping a control time T of PLMN periodic attempts;

[0230] d) postponing one or more periodic attempts of performing network search;

[0231] e) storing parameters carried by the first message previously rejected;

[0232] g) entering a first state, the first state being a state in which the terminal performs the power saving operation.

[0233] Optionally, the first state comprises at least one of:

[0234] a) EMM-DEREGISTERED.ATTEMPTING-TO-ATTACH;

[0235] b) EMM-DEREGISTERED.NO-CELL-AVAILABLE;

[0236] c) EMM-REGISTERED.ATTEMPTING-TO-ATTACH;

[0237] d) EMM-REGISTERED.NO-CELL-AVAILABLE.

[0238] 7) starting a first timer, during which the terminal cannot reattempt the first procedure in the current network;

[0239] In an embodiment, the first information comprises a first time value. The UE starts a first timer according to the first time value or according to a default time range, during which the UE cannot reattempt the first procedure previously rejected in the current network.

[0240] Optionally, the first procedure is integrity protected, and the UE starts the first timer using the first time value.

[0241] Optionally, the first procedure is not integrity protected, and the UE randomly selects a time value within a default time range (agreed by protocol, for example, the default time range is 2-3 hours) as a fifth time value, and starts the first timer according to the fifth time value.

[0242] f) abandoning the first procedure;

[0243] g) associating the current first network device identity with the current PLMN, for reinitiating the previously rejected first procedure to the network;

[0244] Optionally, the second identity can be a second list including one or more target device identities, for example, a store-and-forward monitoring list, and the terminal can attempt the first procedure to the one or more target devices under the current network.

[0245] If the first network device lacks UE information, the first information sent to the UE can be untrusted or unreasonable, and in this embodiment, the UE retry behavior when the first procedure is rejected by the first network device can be controlled by configuring a third time value or a fourth time value for the UE. Optionally, the third time value or the fourth time value represents a UE retry waiting time or a maximum waiting time configured under a store-and-forward satellite service (S&F satellite service), and optionally, the waiting time or the maximum waiting time can be 2 hours.

[0246] Further, the first message is rejected by the first network device, and the cause value can be the above-mentioned cause value #22, #xx (first cause value) specified in the related art.

[0247] In an embodiment, in a case where 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 according to the first information. Specifically, if the first time value received by the UE is not greater than the configured third time value, it is indicated that the first information provided by the first network device is reasonable, and therefore the UE performs the power saving operation.

[0248] In an embodiment, in a case where 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 according to the first information. Specifically, if the first time value received by the UE is greater than the configured third time value, the UE performs the cell or network selection operation.

[0249] Optionally, the operation of performing cell or network selection includes at least one of the following:

[0250] a) Perform cell or network (i.e., PLMN) selection;

[0251] b) When performing cell or network selection, do not select the first network device or the current network;

[0252] 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.

[0253] c) Abandon the first process;

[0254] d) Entering the second state;

[0255] e) Retry the first process in the selected cell or network.

[0256] 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.

[0257] 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.

[0258] 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.

[0259] 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:

[0260] 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.

[0261] b) The UE performs a cell or network selection operation.

[0262] Step 4: The first network device synchronizes the acquired UE information and the first message with the ground network, and the ground network provides the necessary UE information (e.g., authentication vector or subscription information, etc.) to the next satellite network device that can serve the UE.

[0263] Step 5: When the first timer expires and the UE receives the identity of the second network device from the broadcast information, the identity of the second network device is in the stored first identity, the UE sends a second message to the second network device, the second message is used to re-initiate the first process that has not been completed before, and the second message contains the same content as the first message.

[0264] Step 6: The second network device sends a third message to the UE, the third message is used to indicate acceptance of the second message.

[0265] Optionally, the third message includes at least one of the following:

[0266] a) a seventh time value, the seventh time value is used to indicate the waiting time for the terminal to re-attempt the first process;

[0267] b) a third identity;

[0268] Optionally, the third identity can be a third list including the identity of one or more target devices, such as a store-and-forward monitoring list (S&F monitoring list), and the terminal can re-attempt the first process to one or more target devices under the current network.

[0269] c) an eighth time value, used to indicate data uplink transmission time;

[0270] Optionally, the data uplink transmission time can be the time for data to be transmitted from the terminal to the ground network, or can also be the time for data to be transmitted from the non-ground network device to the ground network.

[0271] Optionally, the eighth time value can be an estimated UL delivery time.

[0272] Optionally, the UE replaces the stored first time value and first identity with the received seventh time value and third identity.

[0273] The purpose of providing the seventh time value and the third identity again in the third message is to update the UE related information in time. After the second network device communicates with the ground network, it can obtain the changed UE related information, and thus synchronize with the UE.

[0274] Step 7: When the UE is in idle state and has uplink data to transmit, the UE sends a fourth message to the third network and starts a second timer associated with the fourth message. The fourth message is used to carry the uplink data.

[0275] 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, and in narrowband mode, the value of T3417 is 5+240=245 seconds.

[0276] Optionally, if the UE is in store-and-forward mode and receives a sixth time value (for example, estimated UL delivery time or estimated DL delivery time), the UE sets the second timer using the received sixth time value, and the value of the second timer is not less than the sixth time value.

[0277] Step 8: If the third network device directly rejects the fourth message of the UE due to the lack of necessary information of the UE, the third network device directly rejects the fourth message of the UE, as in step 2. However, if the third network device stores the necessary information of the UE, the third network device accepts the fourth message, including the following two schemes:

[0278] Step 8a: In the case that the signaling interface (for example, S11-U) between the user plane and the 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 an acceptance message of the fourth message to the UE.

[0279] According to the related art, if the signaling interface (S11-U) between the user plane and the control plane in the core network architecture is not established, the MME triggers a setup process, and after the setup is completed, the MME forwards the data to the SGW, and then the MME sends an acceptance message of the fourth message to the UE. In order to ensure the successful transmission of data without modifying the behavior of the UE, the behavior of the network needs to be enhanced.

[0280] Step 8b: The third network device sends an acceptance message of the fourth message to the UE after the data is forwarded to the SGW, which means that the third network device sends an acceptance message of the fourth message to the UE after interacting with the ground network.

[0281] If the UE starts the second timer with an existing value in step 7, after the second timer expires, the UE may not have received the acceptance message of the fourth message, and the UE considers that the transmission of the fourth message fails, that is, the data transmission fails.

[0282] Step 9: Optionally, the third network device sends a fifth message to the UE, and the fifth message is used to indicate that the fourth message is accepted.

[0283] Optionally, the fifth message comprises at least one of:

[0284] 1) an eighth time value, the eighth time value is used to indicate a waiting time for the terminal to re-try the first procedure;

[0285] 2) a fourth identity;

[0286] Optionally, the fourth identity can be a fourth list comprising one or more target identities, for example, a store-and-forward monitoring list (S&F monitoring list), the terminal can re-try the first procedure to one or more target devices under the current network.

[0287] 3) a ninth time value, used to indicate a data uplink transmission time.

[0288] Optionally, the ninth time value can be an estimated UL delivery time.

[0289] Step 10: the UE determines that the data transmission is successful when at least one of the following conditions is met:

[0290] 1) the UE receives the fifth message before the second timer expires.

[0291] a) the UE sets the second timer using the seventh time value, the third network device sends the fifth message to the UE after interacting with the ground network, and since the second timer is relatively large, the UE will receive the fifth message before the second timer expires;

[0292] b) the UE uses the existing second timer, and the third network device immediately sends the fifth message to the UE, so that the UE will receive the fifth message before the second timer expires;

[0293] 2) the second timer expires and the UE is in a store-and-forward mode, and the UE does not receive a rejection message of the fourth message.

[0294] Optionally, the UE can re-send the fourth message to the network device in the first identity.
