Description

BROADCAST OF SATELLITE CONNECTIVITY TIMES FOR STORE AND FORWARD OPERATION
TECHNOLOGICAL FIELD
[0001] An example embodiment relates generally to broadcast of satellite connectivity times and, more particularly, to broadcast of satellite connectivity times for a store and forward operation.
BACKGROUND
[0002] In traditional systems, a user equipment may transmit uplink data to a satellite. The satellite may then immediately relay the uplink data to a network node (e.g., through a gateway to a core network) and an application. The network node and/or application then immediately transmits a response including downlink data to the user equipment, including an acknowledgment of the uplink data. There are many issues with traditional systems, including having to have a large number of satellites active to be available to immediately relay data between a user equipment and a network node.
[0003] In non-terrestrial networks, a store and forward operation may be used to reduce the number of satellites that are in operation. The store and forward operation involves a discontinuous coverage scenario where satellites are not always connected with user equipment or network nodes. Using store and forward operations, a user equipment may transmit uplink data to a satellite which is not currently connected to a network node. The satellite stores this data and relays the data to a network node once it is connected to a non-terrestrial network gateway or ground station. Downlink data is transmitted from the network node to a satellite or another satellite, which may not be connected at that time to the user equipment. The receiving satellite stores the downlink data until it is connected with the user equipment and relays it to the user equipment at that time. Using this method, low-cost deployment of fewer satellites and ground stations is possible. Connectivity cost per device is further reduced if only delay tolerant data is supported. However, a number of challenges are presented by the store and forward scenario. Unnecessary retransmissions may occur from the user equipment while it is waiting to receive an answer from a network node or application. In addition, a user equipment may waste power monitoring paging from satellites that are not storing a response from the network node or application.

[0035] As used herein, the term “computer-readable medium” refers to non-transitory storage hardware, non-transitory storage device or non-transitory computer system memory that may be accessed by a controller, a microcontroller, a computational system or a module of a computational system to encored thereon computer-executable instructions or software programs. A non-transitory “computer readable medium” may be accessed by a computational system or a module of a computational system to retrieve and/or execute the computerexecutable instructions or software programs encoded on the medium. Examples of non- transitory computer-readable media may include, but are not limited to, one or more types of hardware memory, non-transitory tangible media (for example, one or more magnetic storage disks, one or more optical disks, one or more universal synchronous bus (USB) flash drives), computer system memory or random-access memory (such as dynamic random access memory (DRAM), static random access memory (SRAM), extended data out random access memory (EDO RAM), and the like.
[0036] As illustrated in FIG. 1, a system 100 is provided in accordance with an example embodiment in order to broadcast connectivity times for a store and forward operation. Although the system may be configured in various manners, the system of one embodiment is depicted in FIG. 1 and includes user equipment 110, at least one network node 112, and satellites 114-118 configured to communicate via uplink and downlink transmission and reception beams. Although one user equipment, one network node, and three satellites are depicted, the system may include and the user equipment 110, at least one network node 112, and satellites 114-118 may communicate with additional user equipment, network nodes, and satellites in other embodiments. In one or more embodiments, the user equipment 110, at least one network node 112, and satellites 114-118 may be configured to support, for example, 5G, 5G advanced, or 6G. In one or more embodiments, the system 100 may support carrier aggregation and/or dual connectivity. As described below, the system may support non-terrestrial networks and mobile originated traffic.
[0037] The data that is transmitted via the uplink and downlink beams between the user equipment 110, at least one network node 112, and satellites 114-118 may be any of a wide variety of data including, but not limited to digital imagery data including video data, audio data as well as data provided by sensors, radars, telescopes and radio receivers. In at least some instances, the data is encoded prior to communication of the data via the uplink and downlink beams and decoded upon reception. The resulting data received may be utilized for a variety of purposes including presentation to a user, storage of the data for subsequent use and/or provision of the data to one or more applications, such as applications that perform statistical inference on the data for various purposes including object recognition, image classification, spectrum sensing, speech transcription and/or prediction or detection of events.
[0038] The user equipment 110 of FIG. 1 (also called UE, user device, user terminal, terminal device, etc.) illustrates a type of an apparatus which resources on an air interface are allocated and assigned. The user equipment 110 typically refers to a portable computing device that includes wireless mobile communication devices operating with or without a subscriber identification module (SIM), including, but not limited to, the following types of devices: a mobile station (mobile phone), smartphone, personal digital assistance (PDA), handset, device using a wireless modem (alarm or measurement device, etc.), laptop and/or touch screen computer, tablet, game console, notebook, and multimedia device. User equipment 110 may also be a device having capability to operate in Internet of Things (loT) network which is a scenario in which objects are provided with the ability to transfer data over a network without requiring human- to-human or human- to-computer interaction. The user equipment 110 may also be called a subscriber unit, mobile station, remote terminal, access terminal, user terminal, or user equipment (UE) just to mention but a few names or apparatuses. The user equipment 110 may be connected via radio resource control. The user equipment may be in a radio resource control inactive mode or a radio resource control idle mode.
[0039] The network node 112 of FIG. 1 may include, for example, a gateway, core network, application, or other network node on the ground. In some examples, at least one network node 112 is configured to communicate with user equipment 110 through a store and forward operation.
[0040] The satellites 114-118 may be configured to relay signals from, for example, at least one network nodes 112 to user equipment 110. The satellites 114-118 may be configured to store signals from user equipment 110 and/or at least one network node 112 and later forward them to a user equipment 110 and/or at least one network node 112. [0041] FIG. 2 depicts an example apparatus 200 that may be configured to function as user equipment 110, at least one network node 112, and/or satellites 114-118. As shown in FIG. 2, the apparatus includes, is associated with, or is in communications with processing circuitry 220, a memory 240, and a communication interface 260. The processing circuitry 220 may be in communication with the memory device 240 via a bus for passing information among components of the apparatus. The memory device may be non-transitory and may include, for example, one or more volatile and/or non-volatile memories. In other words, for example, the memory device may be an electronic storage device (e.g., a computer readable storage medium) including gates configured to store data (e.g., bits) that may be retrievable by a machine (e.g., a computing device like the processing circuitry). The memory device may be configured to store information, data, content, applications, instructions, or the like for enabling the apparatus to carry out various functions in accordance with an example embodiment of the present disclosure. For example, the memory device could be configured to buffer input data for processing by the processing circuitry. Additionally or alternatively, the memory device could be configured to store instructions for execution by the processing circuitry.
[0042] The apparatus 200 may, in some embodiments, be embodied in various computing devices described as above. However, in some embodiments, the apparatus may be embodied as a chip or chip set. In other words, the apparatus may include one or more physical packages (e.g., chips) including materials, components and/or wires on a structural assembly (e.g., a baseboard). The structural assembly may provide physical strength, conservation of size, and/or limitation of electrical interaction for component circuitry included thereon. The apparatus may therefore, in some cases, be configured to implement an embodiment on a single chip or as a single “system on a chip.” As such, in some cases, a chip or chipset may constitute means for performing one or more operations for providing the functionalities described herein.
[0043] The processing circuitry 220, also referenced as a processor, may be embodied in a number of different ways. For example, the processing circuitry may be embodied as one or more of various hardware processing means such as a coprocessor, a microprocessor, a controller, a digital signal processor (DSP), a processing element with or without an accompanying DSP, or various other circuitry including integrated circuits such as, for example, an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), a microcontroller unit (MCU), a hardware accelerator, a special-purpose computer chip, or the like. As such, in some embodiments, the processing circuitry may include one or more processing cores configured to perform independently. A multi-core processing circuitry may enable multiprocessing within a single physical package. Additionally or alternatively, the processing circuitry may include one or more processors configured in tandem via the bus to enable independent execution of instructions, pipelining, and/or multithreading.
[0044] In an example embodiment, the processing circuitry 220 may be configured to execute instructions stored in the memory device 240 or otherwise accessible to the processing circuitry. Alternatively or additionally, the processing circuitry may be configured to execute hardcoded functionality. As such, whether configured by hardware or software methods, or by a combination thereof, the processing circuitry may represent an entity (e.g., physically embodied in circuitry) capable of performing operations according to an embodiment of the present disclosure while configured accordingly. Thus, for example, when the processing circuitry is embodied as an ASIC, FPGA or the like, the processing circuitry may be specifically configured hardware for conducting the operations described herein. Alternatively, as another example, when the processing circuitry is embodied as an executor of instructions, the instructions may specifically configure the processor to perform the algorithms and/or operations described herein when the instructions are executed. However, in some cases, the processing circuitry may be a processor of a specific device (e.g., an image or video processing system) configured to employ an embodiment by further configuration of the processing circuitry by instructions for performing the algorithms and/or operations described herein. The processing circuitry may include, among other things, a clock, an arithmetic logic unit (ALU) and logic gates configured to support operation of the processing circuitry.
[0045] The communication interface 260 may be any means such as a device or circuitry embodied in either hardware or a combination of hardware and software that is configured to receive and/or transmit data including media content in the form of video or image files, one or more audio tracks or the like. In this regard, the communication interface may include, for example, an antenna (or multiple antennas) and supporting hardware and/or software for enabling communications with a wireless communication network. Additionally or alternatively, the communication interface may include the circuitry for interacting with the antenna(s) to cause transmission of signals via the antenna(s) or to handle receipt of signals received via the antenna(s). In some environments, the communications interface may alternatively or also support wired communication. As such, for example, the communication interface may include a communication modem and/or other hardware/software for supporting communication via cable, digital subscriber line (DSL), universal serial bus (USB) or other mechanisms.
[0046] Turning now to FIG. 3, an illustration of problems with the store and forward operation is provided in accordance with previous embodiments. In this scenario, a user equipment 110 connects to satellites 114-118 as they are passing between a first gateway 302 and a second gateway 304. The satellites 114-118 are configured to receive and store uplink data from a user equipment until they can connect again to a core network via second gateway 304. The satellites 114-118 are also configured to receive and store downlink data from a core network via first gateway 302 and transmit it to user equipment 110.
[0047] At step 306, a user equipment 110 connects to satellite 114. The user equipment 110 uploads uplink data to satellite 114 and expects a response from the application at the other end. The user equipment 110 may expect an acknowledgment or some other response, so it begins monitoring the paging channel.
[0048] At step 308, satellite 116 arrives and the user equipment 110 monitors the paging channel for it. However, satellite 116 cannot carry an acknowledgment as it had connectivity with the core network through gateway 302 before satellite 114 was able to connect to the core network through gateway 304. Therefore, the application had not yet received the uplink data from satellite 114 and could not provide feedback. The user equipment 110 is wasting energy monitoring paging for satellite 116 as it could otherwise be in a power saving mode.
[0049] At step 310, the user equipment is able to receive the acknowledgment via satellite 118. Satellite 118 was last connected with the core network via gateway 302 after satellite 114 connected via gateway 304. Therefore, satellite 118 carries application data from the core network in response to the uplink data and is able to transmit it to user equipment 110.
[0050] Turning now to FIG. 4, a user equipment entering a power savings mode between transmitting and receiving data is provided in accordance with example embodiments of the present disclosure. In this example embodiment, each of satellites 114-118 broadcasts a system information block (SIB) indicating the time in which the satellite last connected to the core network and the time it expects to be connected to the core network in the future.
[0051] In one or more embodiments, at step 306, the user equipment 110 connects to satellite 114. In one or more embodiments, user equipment 110 reads SIB 406 indicating times when the satellite was last connected to core network (e.g., through gateway 302) and when it expects to connect again (e.g., through gateway 304). In one or more embodiments, the user equipment 110 uploads the uplink data. In some examples, the user equipment records the time that satellite 114 expects to be connected to the core network.
[0052] In one or more embodiments, at step 308, the user equipment 110 reads SIB 404 broadcast from satellite 116 indicating that the satellite 116 was last connected to the core network before satellite 114 expects to connect to the core network again. In some examples, the user equipment 110 remains in a power saving mode and does not monitor paging. In some examples, the user equipment will not monitor paging (i.e., check any paging message) until it reads a SIB from a satellite indicating that it previously connected to the core network after the time that satellite 114 expects to be connected to the core network. In further examples, the user equipment 110 may factor in a safety margin after the time that satellite 114 expects to connect to the core network to cover for transport to the application and application processing.
[0053] In one or more embodiments, at step 310, the user equipment 110 reads SIB 406 from satellite 118. In some examples, the user equipment 110 determines that satellite 118 was last connected to the core network via gateway 302 after satellite 114 expected to connect with the core network via gateway 304. In this example, the user equipment 110 monitors paging and receives the acknowledgment from the core network.
[0054] Turning now to FIG. 5, a flow diagram of a user equipment 110 minimizing power consumption by skipping paging monitoring of a satellite 116 is provided in accordance with example embodiments of the present disclosure.
[0055] In one or more embodiments, at operation 502, first satellite 114 is connected to at least one network node 112 (core network). In some examples, at a first time 502a, the first satellite 114 releases connection from the at least one network node 112. In some examples, this may result from first satellite 114 flying out of reach from a gateway.
[0056] In one or more embodiments, at operation 504, the first satellite 114 broadcasts a SIB 504a. In some examples, the SIB 504a indicates the first time 502a in which the first satellite 114 was previously connected to the at least one network node 112 and a second time 514a in which the first satellite 114 expects to next connect to the at least one network node 112. In some examples, the user equipment 110 reads the SIB 504a and stores the second time 514a. In some examples, SIB 504a includes a safety margin applied to second time 514a to allow time for data Y1 to be transmitted to and from a core network. In some examples, the SIB 504a may be used to determine whether and when user equipment 110a should retransmit certain application data, because the user equipment 110a will have a better understanding of whether data has reached the at least one network node 112.
[0057] In one or more embodiments, at operation 506, the user equipment 110 uploads uplink data 506a to the first satellite 114.
[0058] In one or more embodiments, at operation 508, second satellite 116 is connected to network node 112 (core network). In some examples, at a third time 508a, the second satellite 116 releases connection from the at least one network node 112. In some examples, this may result from second satellite 116 flying out of reach from a gateway.
[0059] In one or more embodiments, at operation 510, the second satellite 116 broadcasts a SIB 510a. In some examples, the SIB 510a indicates the third time 508a in which the second satellite 116 was previously connected to the at least one network node 112 and a fourth time in which the second satellite 116 expects to next connect to the at least one network node 112.

In some examples, the satellites 114-118 may indicate a next number of times in which they may connect to the at least one network node 112, such that if user equipment 110 deducts that a satellite 114-118 did not connect at the first expected opportunity (e.g., by missing a gateway), the user equipment 110 determines a next possible opportunity and enters a power saving mode until then.
