METHODS AND APPARATUS FOR INDICATING STORE AND FORWARD PARAMETERS TO TERMINAL IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure claims the priority benefit of Indian Patent Application No. 202421075244, filed 04 October 2024, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to indicating store and forward parameters to a mobile terminal in mobile communications.BACKGROUND
[0003] In wireless communications such as mobile communications under the current 3rd Generation Partnership Project (3GPP) specification, a “Store and Forward Satellite operation” mode refers to an operation mode providing communication service to a user equipment (UE) in periods of time and / or geographical areas in which a serving satellite is not simultaneously connected to a ground network. Additionally, a “S&F mode” refers to a mode in which the UE, a radio access network (RAN) and a core network perform the Store and Forward Satellite operation. The Store and Forward Satellite operation in an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) system with satellite access provides communication service for UEs in periods of time and / or geographical areas in which the satellite serving a UE does not have a simultaneous service link connection and feeder link connection. The Store and Forward Satellite operation is suitable for delay-tolerant communication services (e.g., Cellular Internet-of-Things (CIoT) / Machine Type Communication (MTC) , Short Message Service (SMS) , and so on) .
[0004] In Store and Forward Satellite Operation, the end-to-end exchange of signaling / data traffic is handled as a combination of two or more steps that are not concurrent in time. In the first step, signaling / data exchange between the UE and the satellite occurs without the satellite being simultaneously connected to the UE via the service link and ground network via the feeder link. The satellite moves from being connected to the UE in the first step to being connected to the ground network in the second step. In the second step, the connectivity between the satellite and the ground network is established so that communication between the satellite and the ground network can take place and the end-to-end exchange can be completed.
[0005] In the S&F mode, the Mobility Management Entity (MME) is to reject the non-access stratum (NAS) procedure defined in the 3GPP Technical Specification (TS) 24.301
[0046] , if this cannot be completed with the information currently available in the satellite (e.g., the MME does not have UE security context or, if integrity check fails, and / or if the MME fails to retrieve UE-specific authentication vectors or subscription information) . In the related NAS procedure as defined in TS 24.301
[0046] , MME supporting S&F is to include a S&F reject cause code. The MME may also include a S&F wait timer and a list of satellites (i.e., S&F Monitoring list) from the same (UE selected) public land mobile network (PLMN) with which the UE can attempt to retry the related NAS procedure as defined in TS 24.301
[0046] , in the future.
[0006] Upon or after expiry of the S&F wait timer, the UE may reattempt the related NAS procedure as defined in TS 24.301
[0046] , towards any of the satellites among the list of satellites in the S&F Monitoring List provided during rejection. If during the reattempt of related NAS procedure as defined in TS 24.301
[0046] , the MME has the UE context, authentication vectors and subscription data, the MME accepts the request and may indicate the estimated UL delivery time to UE. Additionally, the MME may include a S&F wait timer to indicate to the UE the time. The UE is to wait before triggering any subsequent NAS procedure with one of the satellites of the same PLMN within S&F Monitoring list from the same (UE selected) PLMN, to indicate to the UE which are the satellites for triggering subsequent NAS procedures.
[0007] However, the upper layer, application layer or terminal may not be aware of uplink (UL) delivery time, S&F timer, monitoring list for further UL data or signaling with network. Undesirably, this would result in failure of signaling and data if it is not being transmitted considering the above-listed parameters. Therefore, there is a need for a solution of indicating store and forward parameters to a mobile terminal in mobile communications.SUMMARY
[0008] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits, and advantages of the novel and non-obvious techniques described herein.

More specifically, various schemes proposed in the present disclosure are believed to provide solutions pertaining to indicating store and forward parameters to a mobile terminal in mobile communications. It is believed that implementations of one or more of the schemes proposed herein may address or otherwise alleviate the issues described above.
[0010] In one aspect, a method may involve a UE receiving, from a network, information of one or more parameters associated with a store and forward (S&F) satellite operation. The method may also involve a modem of the UE providing the information of the one or more parameters to a terminal equipment (TE) or application layer or user interface of the UE using an attention (AT) command.
[0011] In another aspect, a method may involve a network node of the network determining that the network is in a S&F satellite operation. The method may also involve the network node transmitting, responsive to the determining, to a UE information of one or more parameters associated with the S&F satellite operation such that a modem of the UE provides the information of the one or more parameters to a TE or application layer or user interface of the UE using an AT command.
[0012] In still another aspect, an apparatus implementable in a UE may include a transceiver configured to communicate wirelessly and a processor coupled to the transceiver.

However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0020] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to indicating store and forward parameters to a mobile terminal in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0021] FIG. 1 illustrates an example network environment 100 in which various solutions and schemes in accordance with the present disclosure may be implemented. FIG. 2 ~ FIG. 4 illustrate examples of implementation of various proposed schemes in network environment 100 in accordance with the present disclosure. The following description of various proposed schemes is provided with reference to FIG. 1 ~ FIG. 4.
[0022] Referring to FIG. 1, network environment 100 involves a UE 110 in wireless communication with a wireless network 120 (e.g., a mobile network including a non-terrestrial network (NTN) and a terrestrial network (TN) ) via a terrestrial network node 125 (e.g., an evolved Node-B (eNB) , a Next Generation Node-B (gNB) , or a transmission / reception point (TRP) ) and / or a non-terrestrial network node 128 (e.g., a satellite) . For example, the terrestrial network node 125 and / or the non-terrestrial network node 128 may form an NTN serving cell for wireless communication with the UE 110. In some implementations, the UE 110 may be an IoT device such as an NB-IoT UE or an enhanced machine-type communication (eMTC) UE (e.g., a bandwidth reduced low complexity (BL) UE or a coverage enhancement (CE) UE) . In such communication environment, the UE 110, the network 120, the terrestrial network node 125, and the non-terrestrial network node 128 may implement various schemes pertaining to indicating store and forward parameters to a mobile terminal in mobile communications in accordance with the present disclosure, as described below.
[0023] It is noteworthy that, while the various proposed schemes may be individually or separately described below, in actual implementations some or all of the proposed schemes may be utilized or otherwise implemented jointly. Of course, each of the proposed schemes may be utilized or otherwise implemented individually or separately. Moreover, as used herein, a lower layer may refer to a layer in the 5GMM protocol stack that is lower than the radio resource control (RRC) layer, such as a packet data convergence protocol (PDCP) layer, a radio control link (RLC) layer, a medium access control (MAC) layer, a physical (PHY) layer, or so forth.
[0024] Under various proposed schemes in accordance with the present disclosure, to solve the aforementioned issue, a new or existing interface (e.g., message, indicator, method) from a 3GPP modem to a terminal equipment (TE) or an application layer or a user interface, from lower layers to upper layers (e.g., using Attention (AT) Command) , maybe utilized to report store and forward operation-related parameters and / or information such as, for example, a S&F wait timer duration to indicate to a UE (e.g., UE 110) the time or duration of the S&F satellite operation, a S&F monitoring list of one or more satellites, an estimated UL delivery time, S&F information received / broadcasted in a NAS message from a network, S&F information determined or derived from a system information block (SIB) which may be broadcasted from a camped cell or other way to the UE over an access stratum (AS) signaling or over NAS protocol signaling, a list of satellites, and information on S&F feature support, and so on, to the application layer or terminal equipment or user interface (e.g., from the lower layers to the upper layers) . Under the proposed schemes, the interface may include UE implementation-specific AT-command (s) , and / or other UE-internal signaling from the AS and / or NAS to applications, and / or predefined standardized AT-command (s) .
[0025] As an implementation example, a new AT command may be utilized as Store and forward information +CSTFOR (coordinated short message (SM) transfer over radio) which may include one or more of the following parameters: (i) a S&F wait timer duration, (ii) an estimated UL delivery time, (iii) a S&F monitoring list of one or more satellites, and (iv) an indication of S&F feature support. For illustrative purposes only and without limiting the scope of the present disclosure, an example table to be defined in the 3GPP specification is provided below. Table X. ab-z: +CSTFOR parameter command syntax
[0026] The Set command may control the presentation of unsolicited result code + CSTFOR: <S&F wait timer>, <estimated UL delivery time>, <S&F monitoring list> when <n>=1 indicator is indicating the store and forward satellite operation. The Read command may return the current settings of <n> and the indicator for discontinuous coverage situation. The Test command may return supported <n>s values as a compound value.
[0027] The following is a listing of defined values under the proposed schemes. <n>: integer type.0 Disable presentation of the unsolicited result code +CSTFOR: <S&F wait timer>, <estimated UL delivery time>, <S&F monitoring list> 1 Enable presentation of the unsolicited result code +CSTFOR: <S&F wait timer>, <estimated UL delivery time>, <S&F monitoring list>. <S&F feature support>: integer type. Indicates the store and forward satellite feature support by the network.0 indicates that the store and forward satellite feature is not supported by the network. 1 indicates that the store and forward satellite feature is supported by the network. <S&F wait timer>: string type; one byte in an 8 bit format. The <S&F wait timer> value is coded as one byte (octet 3) of the GPRS Timer 3 information element coded as bit format (e.g. "01000111" equals 70 hours) . For the coding and the value range, see the GPRS Timer 3 IE in 3GPP TS 24.008 Table 10.5.163a / 3GPP TS 24.008. See also 3GPP TS 24.501 clause 5.3.26. The default value, if available, is manufacturer specific. < estimated UL delivery time >: string type; one byte in an 8 bit format.

It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0054] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0055] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “asystem having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
