Description

Electronic device for receiving a message using non-terrestrial network communication, method of operation thereof, and storage medium

[0001] One embodiment of the present disclosure relates to an electronic device supporting non-terrestrial network (NTN) communication, a method of operation thereof, and a storage medium.

[0002] The electronic device can support non-terrestrial network (NTN) communication (e.g., satellite communication). As an example, the electronic device can communicate with a satellite of an existing satellite communication provider by utilizing that provider's frequencies and communication methods. The electronic device supports the Long-Term Evolution (LTE) standard (or, 5th generation (5 th Based on the generation: 5G standard, communication with a satellite can be performed using cellular frequencies according to the LTE standard. The electronic device can also perform communication with a satellite based on the 5G NTN standard.

[0003] When an electronic device communicates with an NTN based on LTE standards, some of the frequencies defined in LTE standards may be allocated for non-terrestrial communication. The electronic device may perform satellite communication using the protocol stack used for terrestrial communication, and an additional protocol stack for non-terrestrial communication may not be required. The electronic device may perform communication without distinguishing between non-terrestrial and terrestrial communication. For example, the electronic device may perform operations to perform a cell scan, camp on to a cell satisfying cell selection criteria, and access a network (e.g., may include camp on, random access (RA) procedures, connection establishment procedures, and / or attach (or registration)). The electronic device may perform operations to camp on to a cell satisfying cell selection criteria and access a network without distinguishing between non-terrestrial and terrestrial communication. Accordingly, the electronic device may prepare to perform non-terrestrial communication in substantially the same manner as terrestrial communication.

[0004] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

[0005] According to one aspect of the present disclosure, an electronic device may include at least one processor comprising a communication circuit, a processing circuitry, and a memory for storing instructions, wherein the instructions, when executed individually or collectively by the at least one processor, cause the electronic device to automatically transmit a signal through the communication circuit to the satellite, which causes the transmission of one or more messages that failed to be transmitted to the electronic device during a time interval between a first time point when the NTN service was lost and a second time point when the NTN service was recovered, and to receive the one or more messages from the satellite through the communication circuit.

[0006] The above one or more messages may include at least one short message service (SMS) message. The signal may include a dummy SMS message, and the recipient of the dummy SMS message may include a telephone number corresponding to the electronic device. When the instructions are executed individually or collectively by the at least one processor, the electronic device may be caused to receive, through the communication circuit, the one or more messages that failed to be transmitted to the electronic device during a time interval between a first point in time when the dummy SMS message and the NTN service were lost and a second point in time when the NTN service was recovered.

[0007] When the above instructions are executed individually or collectively by the at least one processor, the electronic device may be caused to transmit the signal through the communication circuit, which causes the transmission of the one or more messages that failed to be transmitted to the electronic device during the time interval between the first time point when the NTN service was lost and the second time point when the NTN service was recovered, based on the fact that the time interval between the first time point when the NTN service was lost and the second time point when the NTN service was recovered is shorter than a critical time interval. The critical time interval may correspond to a value for storing information associated with the failure of message transmission by the satellite.

[0008] The above critical time interval may be defined by the operator of the above NTN service.

[0009] One or more messages that failed to be transmitted to the electronic device during the above critical time interval may be received from the satellite.

[0010] The above signal may include at least one of an internet protocol (IP) data delivery (NIDD) service request, a tracking area update (TAU) request, or a dummy SMS (short message service) message.

[0011] The above one or more messages may include at least one of a short message service (SMS) message, a multimedia messaging service (MMS) message, or a rich communication service (RCS) message.

[0012] According to one aspect of the present disclosure, a method for operating an electronic device may include, after connecting to a satellite for a non-terrestrial network (NTN) service, an operation of confirming that the NTN service is lost; after confirming that the NTN service is lost, an operation of confirming that the NTN service is recovered; based on confirming that the NTN service is recovered, an operation of automatically transmitting a signal that causes one or more messages to be transmitted to the electronic device during a time interval between a first time point when the NTN service is lost and a second time point when the NTN service is recovered, and an operation of receiving the one or more messages from the satellite.

[0013] The above one or more messages may include at least one short message service (SMS) message. The signal may include a dummy SMS message, and the recipient of the dummy SMS message may include a telephone number corresponding to the electronic device. The operation of receiving the one or more messages from the satellite may include receiving the one or more messages that failed to be transmitted to the electronic device during a time interval between a first point in time when the dummy SMS message and the NTN service were lost and a second point in time when the NTN service was recovered.

[0014] The operation of automatically transmitting the above signal to the satellite may further include the operation of transmitting the signal that causes the transmission of one or more messages that failed to be transmitted to the electronic device during the time interval between the first time point when the NTN service was lost and the second time point when the NTN service was recovered, based on the fact that the time interval between the first time point when the NTN service was lost and the second time point when the NTN service was recovered is shorter than a threshold time interval. The threshold time interval may correspond to a value for storing information associated with the failure of message transmission by the satellite.

[0015] The above critical time interval may be defined by the operator of the above NTN service.

[0016] The above signal may include at least one of an internet protocol (IP) data delivery (NIDD) service request, a tracking area update (TAU) request, or a dummy SMS (short message service) message.

[0017] The above one or more messages may include at least one of a short message service (SMS) message, a multimedia messaging service (MMS) message, or a rich communication service (RCS) message.

[0018] According to one aspect of the present disclosure, in a non-transient storage medium storing computer-readable instructions, the instructions, when executed individually or collectively by at least one processor of an electronic device, cause the electronic device to automatically transmit a signal causing the transmission of one or more messages that failed to be transmitted to the electronic device during a time interval between a first time point when the NTN service was lost and a second time point when the NTN service was recovered, based on the confirmation that the NTN service was recovered, after the satellite for non-terrestrial network (NTN) service was connected, and cause the electronic device to receive at least one of the one or more messages from the satellite.

[0019] The above one or more messages may include at least one short message service (SMS) message. The signal may include a dummy SMS message, and the recipient of the dummy SMS message may include a telephone number corresponding to the electronic device. Instructions for causing the electronic device to receive at least one of the one or more messages from the satellite may include instructions that further cause the electronic device to receive the one or more messages that failed to be transmitted to the electronic device during the time interval between a first point in time when the dummy SMS message and the NTN service were lost and a second point in time when the NTN service was recovered.

[0020] The instructions that cause the electronic device to automatically transmit the signal to the satellite may include instructions that cause the electronic device to transmit the signal, which causes the transmission of one or more messages that failed to be transmitted to the electronic device during the time interval between the first time point when the NTN service was lost and the second time point when the NTN service was recovered, based on the fact that the time interval between the first time point when the NTN service was lost and the second time point when the NTN service was recovered is shorter than a threshold time interval. The threshold time interval may correspond to a value for storing information associated with the failure of message transmission by the satellite.

[0021] The above critical time interval may be defined by the operator of the above NTN service.

[0022] One or more messages that failed to be transmitted to the electronic device during the above critical time interval may be received from the satellite.

[0023] The above signal may include at least one of an internet protocol (IP) data delivery (NIDD) service request, a tracking area update (TAU) request, or a dummy SMS (short message service) message.

[0107] In one embodiment of the present disclosure, an electronic device (101) may perform non-terrestrial wireless communication with at least one of a plurality of non-terrestrial wireless communication devices (510) (e.g., a satellite eNB). The electronic device (101) may support NB IoT NTN services, and non-terrestrial wireless communication is not limited thereto. For example, the electronic device (101) may perform a peer-to-peer connection with a satellite eNB based on performing a positioning operation (e.g., position pointing). A plurality of non-terrestrial wireless communication devices (510) may be connected to an NTN core network (520) (or a satellite core entity). The NTN core network (520) may provide satellite services to the electronic device (101) through a plurality of non-terrestrial wireless communication devices (510). The NTN core network (520) may be connected to network entities of a terrestrial communication (TN) operator. Network entities of a terrestrial telecommunications operator may include an interworking function (IWF) (530), a mobile switching center (MSC) (540), and / or an SMS server (550) (or an SMS center).

An SMS instance may include message content and additional information (e.g., context). The context may include information associated with sender information, timestamps, and / or message type (e.g., marketing or notification), and there are no specific limitations on examples of the context. The MSC (540) or SMS server (550) may store a delivery failed SMS as a pending SMS during a critical time interval. The electronic device (101) may lose the SMS message if the SMS instance is not retransmitted from the network.

[0108] FIG. 6 is a diagram illustrating a method of operation of an electronic device according to one embodiment.

[0109] According to one embodiment of the present disclosure, an electronic device (101) can detect the loss of a non-terrestrial network (NTN) service in a 601 operation. In one embodiment, the electronic device (101) may be an electronic device that supports NTN 3GPP and non-3GPP satellite communication. The electronic device (101) may use NB-IoT NTN services when wireless communication through a terrestrial network is not possible. The electronic device (101) may connect (or access) to a satellite for NTN services (e.g., communication networks using satellites or airborne vehicles to provide wireless connectivity). After connecting to a satellite for NTN services, the electronic device (101) may detect that the NTN service is lost. The electronic device (101) may detect the loss of the NTN service, for example, based on detecting a decoding failure of a non-terrestrial wireless communication channel, and there are no limitations on specific examples. The electronic device (101) may include an application processor and a communication processor. The communication processor may detect the loss of NTN service through the application processor or detect the loss of NTN service based on a received signal. The loss of NTN service may be caused by a grip event of the electronic device (101), the location (or height, orientation) of the electronic device (101), and / or an obstacle between the electronic device (101) and the satellite (or satellite eNB). In various examples, the loss of service may indicate "no service," "OOS (out-of-service)" interruption, termination of connectivity, and the service becoming unavailable.

[0110] In one embodiment of the present disclosure, the electronic device (101) may, in a 603 operation, in response to the recovery of the NTN service after the loss of the NTN service, transmit a signal through a communication circuit (e.g., the wireless communication module (192) of FIG. 1 or 2) to the satellite, causing the transmission of one or more messages that failed to be transmitted to the electronic device (101) during the time interval between the loss of the NTN service and the recovery of the NTN service. The electronic device (101) may confirm the recovery of the NTN service after the loss of the NTN service. The electronic device (101) may confirm the recovery of the NTN service, for example, based on the normal decoding of a non-terrestrial wireless communication channel. In various examples, the recovery of the service may indicate the restoration of connectivity and the re-establishment of communication. The operator network providing the NTN service after the recovery of the NTN service may correspond to the operator network providing the NTN service before the loss of the NTN service. The electronic device (101) may automatically transmit the signal to the satellite without user input.

[0111] In one embodiment of the present disclosure, the electronic device (101) may transmit a signal to the satellite that causes one or more messages to be transmitted to the electronic device during the time interval between the loss of the NTN service and the recovery of the NTN service, based on the fact that the time interval between the loss of the NTN service and the recovery of the NTN service is smaller than a critical time interval. The critical time interval may correspond to a value for storing information associated with the failure of message transmission by the satellite. The critical time interval may be defined by the operator of the NTN service. A value corresponding to the critical time interval may be stored in the electronic device (101) (e.g., the processor (120) and / or memory (130) of FIG. 1). The critical time interval stored in the electronic device (101) may include a time interval value set in correspondence with the operator of the NTN service. The critical time interval value may be set in a range of, for example, minutes, and there is no limitation on the specific numerical value. The critical time interval value may be changed by binary updates and / or parameter updates of the electronic device (101). The electronic device (101) can transmit a signal to a satellite (e.g., a non-terrestrial wireless communication device (220)) to notify the NTN core network (520) of the recovery of the electronic device (101) through a communication circuit configured to transmit or receive a signal associated with NTN communication. One or more messages that failed to be transmitted to the electronic device during the time interval between the loss of NTN service and the recovery of NTN service may include, for example, at least one SMS (short message service) message. The signal transmitted by the electronic device (101) to the satellite may include a dummy SMS message. The recipient of the dummy SMS may be a phone number corresponding to the electronic device (101). The dummy SMS message may be a blank message that is returned to the electronic device (101) after being delivered to, for example, an SMS server (550).The content of the SMS text (e.g., DU / #MMYSMS2BIG / #NORED / !) may be changed in accordance with the region or NTN operator of the electronic device (101). The electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101) by transmitting a dummy message (or user data). In one embodiment, the electronic device (101) may transmit a message containing parameters notifying the network of the recovery of the electronic device (101).

[0112] In one embodiment of the present disclosure, a signal transmitted by an electronic device (101) to a satellite in response to the recovery of an NTN service may include at least one of a non-IP data delivery (NIDD) service request, a tracking area update (TAU) request, or a dummy SMS message. For example, a signal transmitted by an electronic device (101) to a satellite in response to the recovery of an NTN service may include a NIDD service request. By transmitting a NIDD service request, the electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101). A signal transmitted by an electronic device (101) to a satellite in response to the recovery of an NTN service may include a TAU request. By transmitting a TAU request, the electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101). The electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101) by transmitting both a NIDD service request and a TAU request. The electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101) by transmitting both a NIDD service request and a dummy SMS. The electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101) by transmitting both a TAU request and a dummy SMS. The electronic device (101) may notify the NTN core network (520) of the recovery of the electronic device (101) by transmitting all of the NIDD service request, the TAU request, and the dummy SMS.

[0113] In one embodiment of the present disclosure, the messaging service is not limited to an SMS messaging service. For example, the message may include at least one of an SMS message, a multimedia messaging service (MMS) message, or a rich communication service (RCS) message.

[0114] In one embodiment of the present disclosure, the electronic device (101) may automatically transmit a signal to a satellite that causes the transmission of one or more messages that failed to be transmitted to the electronic device during the time interval between the loss of the NTN service and the recovery of the NTN service, in response to the recovery of the NTN service without comparison with a threshold time.

[0115] In one embodiment of the present disclosure, an electronic device (101) may receive a message from a satellite in operation 605. The electronic device (101) may receive, through a communication circuit (192), a dummy SMS message and one or more messages that failed to be transmitted to the electronic device during the time interval between the loss of the NTN service and the recovery of the NTN service. The electronic device (101) may receive, through a communication circuit, at least one of the one or more messages that failed to be transmitted to the electronic device during the time interval between the loss of the NTN service and the recovery of the NTN service in response to a signal from the satellite that causes the transmission of one or more messages. At least one of the one or more messages that failed to be received by the electronic device during the critical time interval may be received sequentially from the satellite. The message received from the satellite may include at least one SMS message stored in an SMS server during the time interval between the loss of the NTN service and the recovery of the NTN service. The electronic device (101) can induce the retransmission of missing SMS messages by notifying the NTN core network of the recovery of the electronic device (101). The electronic device (101) can increase the possibility of receiving missing SMS messages during the loss period of the NTN service by transmitting a signal to the satellite that automatically causes the retransmission of missing SMS messages without user input in response to the recovery of the NTN service.

[0116] FIG. 7 is a diagram illustrating a method for an electronic device according to one embodiment of the present disclosure to receive a pending message from an SMS server.

[0117] According to one embodiment of the present disclosure, the electronic device (101) can detect the loss of NTN service in 701 operation.

[0118] In one embodiment of the present disclosure, the SMS server (550) can transmit an SMS message to the electronic device (101) in operation 703. In FIG. 7, the SMS server (550) is shown transmitting the SMS message directly to the electronic device (101), but is not limited thereto. For example, the SMS server (550) can transmit the SMS message to the NTN core network (520). The NTN core network (520) can transmit the SMS message to the non-terrestrial wireless communication device (220). The non-terrestrial wireless communication device (220) can transmit the SMS message to the electronic device (101). Referring to reference numeral 705, the electronic device (101) may miss the SMS message because it is in a state of NTN service loss. The SMS server (550) can determine that SMS reception to the electronic device (101) has failed based on the fact that the signaling interaction established with the electronic device (101) has not been completed.

[0119] In one embodiment of the present disclosure, the non-terrestrial wireless communication device (220) may record the service recovery of the electronic device (101) from the service loss of the electronic device (101) in operation 707 until the expiration of a timer (e.g., T_ntn). The non-terrestrial wireless communication device (220) may request the retransmission of pending SMS instances until the expiration of the timer.

For example, a processor (e.g., processor (120)) of the machine (e.g., electronic device (101)) may call at least one of the one or more instructions stored in the storage medium and execute it. This enables the machine to be operated to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code that can be executed by an interpreter. The storage medium readable by the machine may be provided in the form of a non-transitory storage medium. Here, 'non-temporary' simply means that the storage medium is a tangible device and does not contain a signal (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently and cases where it is stored temporarily.

[0206] According to one embodiment, the method according to the embodiments disclosed herein may be provided by being included in a computer program product. The computer program product may be traded between a seller and a buyer as a product. The computer program product may be distributed in the form of a device-readable storage medium (e.g., compact disc read-only memory (CD-ROM)), or distributed online (e.g., download or upload) through an application store (e.g., Play Store™) or directly between two user devices (e.g., smartphones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily created on a device-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or a relay server.

[0207] According to one embodiment, each component (e.g., module or program) of the components described above may include a singular or multiple entities, and some of the multiple entities may be separated and placed in other components. According to one embodiment, one or more of the components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Generally or additionally, multiple components (e.g., module or program) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each of the components of the multiple components in the same or similar manner as those performed by the corresponding components among the multiple components prior to the integration. According to one embodiment, operations performed by the module, program, or other components may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
