Description

HANDLING ATTEMPT COUNTERS IN ECALL INACTIVITY PROCEDURE IN MOBILE COMMUNICATIONS
CROSS REFERENCE TO RELATED PATENT APPLICATION (S)
The present disclosure claims the priority benefit of Indian Patent Application No. 202421037888, filed 14 May 2024, the content of which herein being incorporated by reference in its entirety.
TECHNICAL FIELD
The present disclosure is generally related to mobile communications and, more particularly, to handling attempt counters in an eCall inactivity procedure in mobile communications.
BACKGROUND
In wireless communications such as mobile communications under the current 3rd Generation Partnership Project (3GPP) specification, there are rules on domain priority and selection for a user equipment (UE) that attempts to make an eCall over Internet Protocol (IP) Multimedia Subsystem (IMS) sessions using an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) or next-generation radio access network (NG-RAN) based on the availability of the circuit switching (CS) or packet switching (PS) domains and the network support for IMS emergency, eCall over IMS, and IMS voice over PS. These rules are defined in the 3GPP specification based on the UE for different initial conditions when an eCall over an IMS session is initiated by the UE. If the E-UTRAN and/or NG-RAN cells available to the UE have different settings, the UE assumes “PS Available” and “ECL” apply to whichever cell that is indicated as providing eCall over IMS support. When support by more than one cell is indicated, the UE may select any cell to attempt eCall over IMS according to the UE implementation.
However, there are abnormal cases that may occur, such as timer T3510 timeout, the UE receiving a REGISTRATION REJECT message with a predefined 5th Generation Mobility Management (5GMM) cause value, or a lower layer failure or release of a non-access-stratum (NAS) signaling connection received from lower layers before a REGISTRATION ACCEPT message or REGISTRATION REJECT message is received. For instance, when an eCall inactivity procedure is performed, the UE stops an abnormal timer T3511 or T3522, but an attempt counter is not reset. As a result, the UE would exit the eCall mode and would not be able to perform a registration procedure.
Therefore, there is a need for a solution of handling attempt counters in an eCall inactivity procedure in mobile communications.
SUMMARY
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. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
An objective of the present disclosure is to propose solutions or schemes that address the issue (s) described herein. More specifically, various schemes proposed in the present disclosure are believed to provide solutions pertaining to handling attempt counters in an eCall inactivity procedure 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.
In one aspect, a method may involve a UE performing an eCall inactivity procedure. In response to performing the eCall inactivity procedure, the method may involve the UE resetting an attempt counter. The attempt counter may include one or more of the following: (1) a registration attempt counter; (2) an attach attempt counter; (3) a tracking area updating attempt counter; and (4) a service attempt counter.
In another aspect, an apparatus implementable in a UE may include a transceiver configured to communicate wirelessly and a processor coupled to the transceiver. The processor may perform an eCall inactivity procedure. In response to performing the eCall inactivity procedure, the processor may reset an attempt counter. The attempt counter may include one or more of the following: (1) a registration attempt counter; (2) an attach attempt counter; (3) a tracking area updating attempt counter; and (4) a service attempt counter.
It is noteworthy that, although the description provided herein may be in the context of certain radio access technologies, networks, and network topologies such as 5G NR/Beyond Fifth-Generation (B5G) mobile communications, the proposed concepts, schemes and any variation (s) /derivative (s) thereof may be implemented in, for and by other types of radio access technologies, networks and network topologies such as, for example and without limitation, 4G/Long-Term Evolution (LTE) , LTE-Advanced, LTE-Advanced Pro, Internet-of-Things (IoT) , Narrow Band Internet of Things (NB-IoT) , Industrial Internet of Things (IIoT) , vehicle-to-everything (V2X) , and non-terrestrial network (NTN) communications. Thus, the scope of the present disclosure is not limited to the examples described herein.

Referring to FIG. 1, network environment 100 may involve a UE 110, such as a mobile device or smartphone, in wireless communication with a wireless network 120 as part of a communication network. The wireless network 120 may be one or more public land mobile networks (PLMNs) including 5G/NR domain, 4G/LTE domain, and 2nd Generation/3rd Generation (2G/3G) domain. UE 110 may initially be in wireless communication with wireless network 120 via a base station or network node 125 (e.g., an eNB, gNB or transmit-receive point (TRP) ) . In network environment 100, UE 110 and the wireless network 120 may implement various schemes pertaining to handling attempt counters in an eCall inactivity procedure in mobile communications in accordance with the present disclosure, as described herein.
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.
Under a proposed scheme in accordance with the present disclosure, when an eCall inactivity procedure is performed by UE 110 (e.g., according to 3GPP Technical Specification (TS) 24.501 subclause 5.5.3 or 3GPP TS 24.301 subclause 5.5.4) , UE 110 may perform one or more operations. Such one or more operations may include, for example: (a) resetting a registration attempt counter; (b) resetting an attach attempt counter; (c) resetting a tracking area updating attempt counter; and (d) resetting a service attempt counter.
As an implementation example, an eCall inactivity procedure may be performed only in 3GPP access and applicable only to a UE (e.g., UE 110) configured for eCall only mode as specified in 3GPP TS 31.102 [22] . The procedure may be started when: (a) the UE is in any 5GMM-REGISTERED substate except substates 5GMM-REGISTERED. PLMN-SEARCH or 5GMM-REGISTERED. NO-CELL-AVAILABLE; (b) the UE is in a 5GMM-IDLE mode or 5GMM-CONNECTED mode with RRC inactive indication; and (c) one of the following conditions applies: (1) timer T3444 expires or is found to have already expired and timer T3445 is not running; (2) timer T3445 expires or is found to have already expired and timer T3444 is not running; or (3) timers T3444 and T3445 expire or are found to have already expired. Moreover, the UE may then perform one or more of the following actions: (a) stopping other running timers (e.g. T3511, T3512) ; (b) if the UE is currently registered to a network for 5th Generation System (5GS) services, performing a deregistration procedure; (c) deleting any 5th Generation Globally Unique Temporary Identifier (5G-GUTI) , tracking area identifier (TAI) list, last visited registered TAI, list of equivalent public land mobile networks (PLMNs) , and ngKSI; (d) entering a 5GMM-DEREGISTERED. eCALL-INACTIVE state; and (e) resetting a registration attempt counter and a service attempt counter.

Additional Notes
The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. 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.
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.
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., “a system 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., “asystem 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. ”
From the foregoing, it will be appreciated that various implementations of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various implementations disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
