Description
METHODS AND APPARATUS OF USER EQUIPMENT CAPABILITY UPDATE IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 714,946, filed 1 November 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 user equipment (UE) capability update in mobile communications.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] In mobile communication, the user equipment (UE) capability transfer procedure is a process that allows the network to obtain information about the capabilities of a UE. This information is crucial for the network to provide services efficiently and to configure a radio connection that the UE can support. When the capability of UE changes, the UE shall perform a registration procedure with the registration type set to mobility registration update and indicate UE radio capability update. However, if the capability change occurs in the connected state, the UE must first release its connection, enter the idle state, and then perform the mobility registration update. Upon receiving this update, the access and mobility management function (AMF) is supposed to delete any stored capability information. If the AMF then sends an N2 request without the UE capability information, and there is no UE capability information available in the radio access network (RAN) , the RAN should request the capability from the UE and upload it to the AMF.
[0005] This approach creates significant problems. The requirement for the UE to release its connection while in the connected state leads to an unnecessary interruption of any ongoing service, such as a data transfer or a voice call. This is problematic even if the changed capability has no effect on the current service or configuration. Furthermore, there is a risk that the network might not re-enquire about the capability of the UE, even when the UE explicitly indicates a needed update in its registration request. In such a scenario, the UE is left with no way of knowing why its capability update was not processed. This can lead to a state of uncertainty and potential operational issues. Accordingly, there is a need for a more reliable method to update UE capability.SUMMARY
[0006] 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.
[0007] An objective of the present disclosure is to propose solutions or schemes that address the aforementioned issues pertaining to user equipment (UE) capability update in mobile communications.
[0008] In one aspect, a method may involve an apparatus entering a connected state with a network node. The method may also involve the apparatus transmitting a request message regarding a capability change to the network node while in the connected state. The method may further involve the apparatus receiving a feedback message regarding the capability change from the network node.
[0009] In another aspect, an apparatus may comprise a transceiver which, during operation, wirelessly communicates with a network node of a wireless network. The apparatus may also comprise a processor communicatively coupled to the transceiver. The processor, during operation, may perform operations comprising entering a connected state with a network node. The processor, during operation, may also perform operations comprising transmitting, via the transceiver, a request message regarding a capability change to the network node while in the connected state. The processor, during operation, may further perform operations comprising receiving, via the transceiver, a feedback message regarding the capability change from the network node.
[0010] In yet another aspect, a method may involve a network node establishing a connection with a UE. The method may also involve the network node receiving a request message regarding a capability change from the UE while the connection is maintained. The method may also involve the network node determining whether the capability change is allowed. The method may further involve the network node transmitting a feedback message based on the determination to the UE.

[0021] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. 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
[0022] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to user equipment (UE) capability update 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.
[0023] FIG. 1A illustrates an example scenario 100a of a communication environment in which various solutions and schemes in accordance with the present disclosure may be implemented. Scenario 100a involves a UE 110 in wireless communication with a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network) consisting of an access network 120 and a core network 130. The UE 110 may be a smart phone, a wearable device, an IoT device, and a tablet, etc. Alternatively, the UE 110 may be a notebook (NB) or personal computer (PC) inserted or installed with a data card which includes a modem and radio frequency (RF) transceiver (s) to provide the functionality of wireless communication. In one embodiment, the access network 120 is connected to the core network 130 by means of the NG interface, more specifically to a user plane function (UPF) by means of the NG user-plane part (NG-u) , and to an access and mobility management function (AMF) by means of the NG control-plane part (NG-c) . The access network 120 may include a base station (BS) 121, which may be connected to multiple UPFs / AMFs for the purpose of load sharing and redundancy. In addition, the core network may include other entities, such as a session management function (SMF) and a unified data management (UDM) , etc. In some embodiments, the access network 120 may include multiple BSs, each of which may provide communication coverage for a geographic coverage area where communications with the UE 110 are supported.
[0024] To optimize configurations, perform correct resource allocation, and ensure efficient and reliable communication, the BS 121 may send a UE capability enquiry message to the UE 110. In response, the UE 110 reports its capabilities, including detailed information about the features it supports or is compatible with in the wireless network. FIG. 1B illustrates an example scenario 100b showing UE capability parameters in a 5G new radio (NR) system. The capabilities of a UE may change for several reasons. For example, the UE might switch its supported radio access technology (RAT) mode, enable or disable certain frequency bands, or toggle services like IP multimedia subsystem (IMS) , non-terrestrial networks (NTN) , and multicast and broadcast service (MBS) . These changes can affect how the UE communicates with the wireless network. Scenario 100a illustrates a procedure for the UE 110 to negotiate a capability update with the wireless network while in the connected state. Specifically, the UE 110 may perform a connection establishment procedure (e.g., radio resource control (RRC) connection establishment procedure) to transition from the idle state to the connected state, or may perform an RRC resume procedure to transition from the inactive state to the connected state. When a capability change occurs while the UE 110 is in the connected state, it may transmit a request message regarding the capability change to the BS 121. The request message may be an RRC message and is transmitted without releasing the connection with the BS 121. In one embodiment, the UE 110 may indicate which part of the capability is changed, such as one or more IMS parameters, one or more radio frequency (RF) parameters, or any parameter shown in scenario 100b; however, the present disclosure is not limited thereto. The BS 121 may then determine if the capability update is allowed based on the current configuration as well as the ongoing procedure (s) , and transmit a feedback message reflecting the determination to the UE 110. The feedback message is an accept message (e.g., UECapabilityUpdateAccept) for an allowed capability change. If the capability change is not allowed, the feedback is a reject message (e.g., UECapabilityUpdateReject) that may include a reject cause and / or a backoff time.
[0025] FIG. 2 to FIG. 4 are diagrams depicting example scenarios of UE capability update procedure in accordance with implementations of the present disclosure. In scenarios 200, 300, and 400, a capability change occurs while the UE is in the RRC connected state. There are several ways for the UE to transfer its updated capabilities to the network without releasing the connection. Scenario 200 in FIG. 2 shows a procedure where the UE transfers its updated capability by piggybacking the relevant information onto a request message sent to the BS. This request message, such as a UE capability update request message (e.g., UECapabilityUpdateRequest) , may contain the new capability data (e.g., UECapabilityInformation) . After receiving the request message, the BS assesses the request for allowance and, if approved, transmits a UE capability update accept message (e.g., UECapabilityUpdateAccept) to the UE. In scenario 300 of FIG. 3, the UE may transmit a request message to the BS regarding the capability change. The BS may trigger a UE capability transfer procedure following the transmission of the accept message (e.g., UECapabilityUpdateAccept) when the change is allowed. Specifically, the BS may transmit a UE capability enquiry message (e.g., UECapabilityEnquiry) to the UE. The UE subsequently transmits a capability information message (e.g., UECapabilityInformation) containing its updated capabilities back to the BS. On the other hand, scenario 400 of FIG. 4 illustrates a more efficient method where the BS piggybacks the UE capability enquiry message directly within the accept message.
[0026] In scenarios 200, 300, and 400, if the BS determines that the change is not allowed, the BS may transmit a UE capability update reject message (e.g., UECapabilityUpdateReject) to the UE. The reject message may include a reject cause and / or a backoff time. Based on the information provided in the reject message, the UE may decide the follow-up action. In one embodiment, the UE may retransmit the request message based on the backoff time. Alternatively, the UE may revert to a previous capability based on the reject cause. In another embodiment, the UE may perform a connection release procedure to transition to the idle state and then trigger a mobility registration update (MRU) procedure. That is, the UE may perform the registration procedure with the registration type set to mobility registration update and include the capability update in the registration procedure.
[0027] In the foregoing embodiments, when the BS permits a UE capability update and has stored the new capability information, the change may become effective for subsequent connections. Furthermore, the updated UE capability is also forwarded / transmitted to another network node (e.g., AMF) and stored therein for mobility. More specifically, if the UE locally releases its current connection and later establishes a new one with the BS, the updated capability information previously reported remains valid and available during the new connection.
[0028] The transmission of a capability change request without a connection release ensures that all ongoing services (e.g., data sessions, calls) remain uninterrupted. Additionally, the UE can expect a feedback message from the network to confirm whether the capability change was allowed. This allows the UE to perform the necessary follow-up actions. Furthermore, the allowed capability change is available for the subsequent connection, ensuring that the UE can immediately leverage its new capabilities upon reconnecting to the network.

[0032] In one aspect, each of processor 512 and processor 522 may be implemented in the form of one or more single-core processors, one or more multi-core processors, or one or more CISC processors.

[0058] 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.
[0059] 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.
[0060] 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., “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. ”
[0061] 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.
