Description

Technical Field

[0001] Embodiments described herein relate to methods and apparatus for providing capability limitation information from a multi-Universal Subscriber Identity Module User Equipment to a network. Background Art

[0002] Multi-USIM - The 3rd Generation Partnership Project (3GPP) is currently studying in Release 18 (Rel-18) how to best support User Equipment (UE) that can manage two or more simultaneous subscriptions (also known as Multi-Universal Subscriber Identity Module (M-USIM)). A single UE is able to have two or more subscription credentials and essentially "act as" two UEs within one device / hardware entity. Although there are mobile terminals (UE) with this property, most operations are not really optimized because there is no specific standardized support for Multi-USIM, e.g. to make it easier for a UE to manage two or more subscriptions simultaneously.

[0003] Several aspects may be addressed. For example, support may need to be provided for the UE to more easily transition between states associated with utilization of subscription 1 (USIM1, connected to a first public land mobile network (PLMN1)) and states associated with utilization or communication using subscription 2 (USIM2, connected to a second PLMN (PLMN2)), as such states may depend on, for example, RRC_CONNECTED in PLMN1 and PLMN2. If the UE has the ability to communicate to both networks using USIM1 and USIM2 simultaneously, such transitions may be straightforward, or may not even be necessary. To enable this to work, there may be a need for at least dual receiver and transmitter chains, designed so that the frequencies used for the two networks do not cause interference to each other, and the radio separation is good enough so as not to cause, for example, intermodulation effects in the device. Still other aspects that the standard may address are the introduction of signaling that allows a UE that is not able to communicate with, for example, two or more networks simultaneously to at least signal to the network that it is leaving the network or is becoming unreachable for the network.

[0004] As described in RP-210316 WID: "Support for Multi-SIM devices for LTE / NR" (herein referred to as "Reference 1"), the work of Release 17 (Rel-17) for multi-USIM focuses on devices with single receiver (Rx) / single transmitter (Tx) or dual-Rx / single-Tx. That is, dual-Rx / dual-Tx UEs are not in scope.

[0005] In Rel.18, 3GPP started studying enhancements to existing procedures to allow a dual-Rx / dual-Tx M-USIM UE to operate in RRC_CONNECTED state simultaneously in both network A and network B. Specifically, a mechanism will be specified to indicate a preference for temporary UE capability restrictions and the removal of such restrictions, as described in RP-220955 WID: "Dual Transmission / Reception (Tx / Rx) Multi-SIM for NR" (referred to herein as "Reference 2").

[0006] There are specific challenge(s) currently.

[0007] In the current framework of the multi-USIM study in Rel-17, it can be assumed that the UE cannot stay in the RRC_CONNECTED state in two networks at the same time, for example, it may not be possible for the UE to receive / send data using one subscription while having an ongoing service using another subscription. For UEs with at least dual-Tx and dual-Rx, the available resources may not be fully utilized when reporting the UE capabilities.

[0008] Specifically, when establishing a connection to a second network (while maintaining a connection to the first network), the UE may be incorrectly configured by the second network (e.g., network B) because the second network configured the UE based on capabilities received during the registration phase, which may no longer be valid (e.g., DC cannot be established because the UE can now only use one transceiver in the network).

[0009] In addition, solutions to this problem have been explored, such as by limiting the capabilities of dual-Tx / dual-Rx UEs in radio resource control (RRC) messages (e.g., UEAssistanceInformation message or UECapababilityInformation message). However, in these solutions, the reported UE capability limitations are not confirmed. In other words, there is no confirmation from the network to indicate whether the UE request is received or accepted. Summary of the invention

[0010] Certain aspects of the present disclosure and embodiments thereof may provide solutions to these or other challenges.

[0011] The MUSIM UE informs the second network (e.g., network B) that its capabilities are limited when establishing or resuming a connection. This notification may be accomplished, for example, by adding an indication in the RRCSetupRequest / RRCResumeRequest message. The UE may then indicate the actual capability limitations in a following RRCSetupComplete / RRCResumeComplete message, or in a UEInformationResponse (if requested by the network), or in a UEAssistanceInformation (if configured by the network), or in a UECapabilityInformation message (if the network sent a UECapabilityEnquiry).

[0012] When establishing or resuming a connection with a second network (Network B) while maintaining a connection with a first network (Network A), the MUSIM UE indicates that its capabilities are limited (e.g., Carrier Aggregation (CA) or Dual Connectivity (DC) is not possible). Four alternative solutions are described: A. One-bit notification 1. The UE includes a 1-bit notification in the RRCSetupRequest or RRCResumeRequest to indicate to the network that its capabilities are limited. 2. The network can implement a temporary "basic" configuration for the UE, waiting for the current capabilities from the UE 3. The UE informs the network of the actual capability limitation in RRCSetupComplete or RRCResumeComplete. 4. The network reconfigures the UE appropriately based on the indicated current UE capabilities. B. Using UEInformationRequest / Response framework 1. The UE indicates that its capabilities are limited by using a new information element in RRCSetupComplete, RRCResumeComplete or RRCReconfigurationComplete. 2. The network uses a temporary "basic" configuration for the UE and retrieves the restricted capabilities (or the capabilities currently supported by the UE) by sending a UEInformationRequest message 3. The UE replies with a UEInformationResponse message, which includes the restricted capabilities (or currently supported capabilities). 4. The network reconfigures the UE appropriately based on the current UE capabilities C. Using the UEAssistanceInformation framework 1. The UE indicates that its capabilities are limited by using a 1-bit notification in RRCSetupComplete or RRCResumeComplete. 2. The network uses a temporary "basic" configuration for the UE and configures the UE to report these restrictions via the UEAssistanceInformation message 3. The UE sends a UEAssistanceInformation message containing restricted capabilities. 4. The network reconfigures the UE appropriately based on the current UE capabilities D. Use UECapabilityEnquiry / UECapabilityInformation framework 1. The UE also includes restricted capabilities, for example, in a separate container and indicates in the UECapabilityInformation message that certain capabilities are restricted 2. The network uses a temporary "basic" configuration for the UE and waits for the UE to provide current capabilities 3. The network reconfigures the UE appropriately based on the current UE capabilities.

[0013] Certain aspects of the present disclosure and its embodiments may provide solutions to these or other challenges. The present disclosure provides methods for how a network can confirm that a dual-Tx / dual-Rx (2Tx / 2Rx) UE has temporarily restricted or unrestricted (unrestricted) its capabilities for M-USIM purposes. This may be: An indication in an RRC message (e.g. RRCReconfiguration) to indicate that the reconfiguration is due to a downgrade of the UE configuration to restricted UE capabilities; • An indication in an RRC message (e.g. RRCReconfiguration) to indicate that the reconfiguration is due to upgrading the UE configuration to full UE capabilities / unrestricted UE capabilities.

[0014] When establishing or resuming connection with network B (while maintaining connection with network A), the M-USIM UE may indicate that its capabilities are limited (e.g., carrier aggregation (CA) or dual connectivity (DC) is not possible), and the network confirms the UE request to limit the UE capabilities.

[0015] Furthermore, the network may provide configuration for both limited and full capabilities in the RRCReconfiguration message, and the UE may confirm to the network which configuration is applied in the RRCReconfigurationComplete message.

[0049] Some embodiments contemplated herein will now be described more fully with reference to the accompanying drawings. The embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art.

[0050] In the present disclosure, "network A" and "network B" are considered to be two networks with which the multi-USIM UE is or can be in RRC_CONNECTED at the same time. However, the solutions described herein are also applicable to the case where the UE is connected to more than two networks, and those skilled in the art will appreciate how these methods will be performed in a scenario with more than two networks.

[0051] A UE may have multiple USIMs (i.e. two or more USIMs), and the use case of multiple USIMs is that different USIMs are associated with different networks, where each network may be a PLMN or a non-public network (NPN). However, it is also possible for a UE to have multiple USIMs associated with the same network, for example, the UE has two USIMs from the same operator (e.g., a user may have one USIM for a personal subscription and another USIM for a work or business subscription), or, for example, the UE has two USIMs from different operators using the same radio access network (RAN) - i.e., different operators share the same RAN. Therefore, although many examples of the methods described herein are based on multiple SIMs being associated with different networks, it can be appreciated that these methods can also be applied to scenarios where multiple USIMs are associated with the same network, in which case "network A" and "network B" as used herein refer to a connection to the network using a first USIM (USIM1) and a connection to the network using a second USIM (USIM2), respectively.

[0052] Furthermore, in the described examples, the network is a PLMN, but without loss of generality, the network may be any type of network, such as a non-public network (NPN). Furthermore, the two (or more) networks to which the UE is connected may be of different types, for example, network A may be a PLMN and network B may be an NPN, or vice versa.

[0053] In addition, although these techniques are described with reference to operations, steps and / or actions performed by a network (e.g., network A or network B), it will be appreciated that such operations, steps and / or actions may be performed by a radio access network (RAN) node in the network (i.e., a node in the network that provides a radio interface for a UE). In a long term evolution (LTE) network, the RAN node may be an eNB or eNodeB, while in a new radio (NR) network, the RAN node may be a gNB or gNodeB.

[0054] The UE's USIM may be in the form of a removable hardware USIM (eg, a SIM card), or it may be an embedded USIM (eUSIM). A particular UE may be able to receive multiple removable hardware USIMs, or have multiple eUSIMs, or may have one or more of both types of USIMs.

[0055] Reference is made herein to "UE capabilities" and this refers to different capabilities or functions of a UE that may be activated / enabled / unrestricted and deactivated / disabled / restricted. Examples of UE capabilities related to the use or non-use of multiple subscriptions / USIMs include the use of dual connectivity (DC), the use of carrier aggregation (CA), the use of multiple input multiple output (MIMO), the use of aggregated uplink (UL) and downlink (DL) bandwidth of frequency range 1 (FR1) and / or frequency range 2 (FR2) carriers, the number of DL and UL secondary cells (SCells) in a primary cell group (MCG) for the first frequency range FR1 and / or the second frequency range FR2 and the number of primary secondary cells (PSCells) / secondary cells (SCells) in a secondary cell group (SCG), a list of carrier frequencies and / or carrier frequency combinations, and UE power classes.

[0056] "UE capabilities" may be defined as UE radio access capabilities, which may also be defined as: A list of containers, each of which indicates the UE capabilities for a certain radio access technology (RAT) or multi-radio dual connectivity (MR-DC) UE capability information message oIt can be segmented o It may contain filters related to: what the network requests from the UE capabilities UE's response to the UECapabilityEnquiry message Containers stored in the core network (CN) and / or RAT nodes, which can be transferred between CN and RAT nodes An ID that can refer to one of the above origin symbols A structure (e.g., message, IE, container) containing features at multiple granularities, e.g., per UE, per band, per band combination (BC), per feature set combination, per feature set, per feature set per contiguous carrier (CC)

[0057] "Restricted UE capabilities" may be defined as a version of UE capabilities, i.e., a UE capability that contains at least one different feature compared to the UE capabilities previously received by the RAT node, wherein the RAT node is informed of the difference in such UE capabilities. This may also be defined as: Only include features not supported by the UE o In this way, a certain version of UE capabilities may contain, for example, NR-DC support to indicate that the UE does not support NR-DC for that version of UE capabilities. There is no need to indicate what the UE supports, as this can be retrieved from the UE capabilities previously received by the RAT node. A list of versions of UE capabilities, for example: o The UE may include one version of the UE capabilities in which it indicates support for NR-DC but not NR CA for at least one band combination; and in another version in which it indicates support for NR CA but not NR-DC for at least one band combination. o A UE may include a version of UE capabilities where it does not include support for features that require 2Tx / 2Tx (eg, 2 or more MIMO layers) from the UE. Registration update procedure, after which the UE may provide the version of the UE capabilities to the RAT node upon request of the RAT node (eg via a UECapabilityEnquiry message).

[0058] Previous disclosures have proposed an advanced procedure to allow a dual-Rx / dual-Tx M-USIM UE to indicate a preference for temporary UE capability restriction so that it can connect to two networks simultaneously. Figure 1 is shown in the figure, and the numbered paragraphs below refer to Figure 1 The signal with the corresponding number in . Figure 1 The process in involves a UE with two USIMs, USIM1 for network A (NW-A) and USIM2 for network B (NW-B). Figure 1 The following signaling is shown in . 1. UE registers to network A. a. The UE uploads the UE capabilities related to network A (labeled as “UEcapA”) to network A. b. Network A configures the UE according to the provided UE capabilities. 2. UE registers to network B. a. The UE uploads the UE capabilities related to network B (labeled as “UEcapB”) to network B. b. Network B configures the UE according to the provided UE capabilities.

[0059] Thus, having registered the UE in both networks and having provisioned the relevant UE capabilities, the UE may have provisioned full capabilities to both networks. 3. The UE starts (one or more) services in network A. a. The UE is in RRC_CONNECTED mode only in network A. b. The UE is in RRC_IDLE / RRC_INACTIVE state in network B. Possible UE behaviors are: for network B, perform camp cell evaluation, perform neighbor cell measurements, perform paging monitoring and / or perform system information block (SIB) reading. 4. After a certain amount of time, the UE needs to connect to Network B. 5. The UE sends UE assistance information (labeled as "UEAssistanceInformation") to network A, requesting to (temporarily) disable certain capabilities. The UE assistance information may indicate specific UE capabilities that the UE wants or needs to disable. 6. Network A accepts the request and disables (possibly temporarily, i.e. for a defined period of time or until a timer expires) certain capabilities of the UE. That is, Network A disables / restricts / deactivates one or more of the UE capabilities that were active or unrestricted before sending the UE assistance information. a. Network A may use the RRC reconfiguration procedure or lower layer means (e.g., medium access control (MAC) Control Element (CE) / Downlink Control Information (DCI) indication) configures the UE with reduced capabilities. b. Network A or UE may trigger adaptation (downgrade) of ongoing services in Network A. 7. The UE connects to network B using certain capabilities. a. The UE is now in RRC_CONNECTED mode in both networks (Network A and Network B). b. Network B may use the RRC reconfiguration procedure or lower layer means (eg MAC CE / DCI indication) to configure the UE with reduced capabilities. c. Network B or UE may trigger adaptation (downgrade) of ongoing services in Network B. 8. The service(s) between the UE and Network A continue at a reduced capacity. 9. After a certain amount of time, the service between the UE and network B ends and the UE disconnects from network B. a. The UE is now in RRC_CONNECTED mode in network A and in RRC_IDLE / RRC_INACTIVE mode in network B. 10. The UE may send UE assistance information to network A, requesting to re-enable certain capabilities. That is, the UE may request to re-enable one or more of the currently restricted or disabled UE capabilities (e.g., one or more of the restricted or disabled UE capabilities in step 6). In some embodiments, the UE may request to re-enable complete (i.e., all) UE capabilities for the UE. 11. Network A may accept the UE request and re-enable all previously disabled capabilities, or may re-enable only a subset of those capabilities (ie one or more, but not all). a. Network A may reconfigure the UE with the re-enabled capabilities using the RRC reconfiguration procedure or lower layer means (eg MAC CE / DCI indication). b. Network A or UE can trigger adaptation (upgrade) of ongoing services in Network A. The UE and Network A continue to use the full (re-enabled) capabilities.

[0060] like Figure 1 As indicated in the process of , the UE is registered to the two networks and can provide full capabilities. However, when the UE connects to network B (while maintaining connection with network A), it may only be able to operate with limited capabilities.

[0061] Embodiments described herein provide methods to allow a MUSIM UE to indicate that its capabilities are limited when establishing or resuming a connection with network B (eg, a second network). Some embodiments also provide methods for providing limited capability indication. Both the UE side and the network side are considered.

[0062] Figure 2 The method according to some embodiments is shown

[0063] Figure 2 Methods according to certain embodiments are shown. Figure 2 The method may be performed by a UE or a wireless device (eg, as described later with reference to Fig.10 and 11The method may be performed by a UE 1012 or UE 1100 as described. The UE may perform the method in response to executing a suitably formulated computer-readable code. The computer-readable code may be implemented or stored on a computer-readable medium (such as a memory chip, an optical disk, or other storage medium). The computer-readable medium may be part of a computer program product. The UE may be configured to communicate with one or more networks using two or more subscriptions simultaneously, wherein the UE has an ongoing first service for the first network according to the first subscription. The method begins at step 202, wherein a second service for the second network is established or resumed according to the second subscription. The first network may be the same as the second network. In step 204, the method includes indicating to the second network that the user equipment has limited capabilities for the second service. The first network may be referred to as network A, and the second network may be referred to as network B.

[0064] In some embodiments, Figure 2 The method also includes transmitting an indication of a first capability that is supported in the second service or an indication of a second capability that is limited in the second service.

The network node may perform the method in response to executing a suitably formulated computer-readable code. The computer-readable code may be implemented or stored on a computer-readable medium (such as a memory chip, an optical disk, or other storage medium). The computer-readable medium may be part of a computer program product. The network node may be part of a second network and may be configured to communicate with a UE that is configured to communicate with one or more networks using two or more subscriptions simultaneously, wherein the UE has an ongoing first service for the first network according to a first subscription. The method begins at step 302, wherein a second service for the UE is established or resumed according to a second subscription. In step 304, the method includes receiving an indication from the UE that the UE has a restricted capability for the second service. The first network may be referred to as network A, and the second network may be referred to as network B. The first network and the second network may be the same network.

[0067] In some examples, step 204 or step 304 occurs when a connection with a second network (eg, network B) is established or restored.

[0068] In some examples, step 204 or step 304 includes the UE transmitting a 1-bit notification to the second network, the 1-bit notification indicating that the user equipment has limited capabilities for the second service.

[0069] In some examples, the 1-bit notification is transmitted in one of: an RRCSetupRequest message (e.g., if in RRC_IDLE state), an RRCResumeRequest message (e.g., if in RRC_INACTIVE state), an RRCSetupComplete message, an RRCResumeComplete message, or an RRCReconfigurationComplete message.

[0070] In some examples, if the UE includes the 1-bit notification in the RRCSetupRequest or RRCResumeRequest, the UE may transmit a list of restricted capabilities in a subsequent RRCSetupComplete or RRCResumeComplete message. In another alternative, the UE sends a list of currently supported features in the RRCSetupComplete or RRCResumeComplete message. In other words, in response to transmitting the 1-bit notification in the RRCSetupRequest message or the RRCResumeRequest message, an indication of a first capability supported in the second service or an indication of a second capability not supported in the second service is transmitted in the message. The message may include an RRCSetupComplete or RRCResumeComplete message.

[0071] In some examples, step 204 or step 304 includes the UE transmitting an information element to the second network, the information element indicating that the user equipment has restricted capabilities for the second service. The information element may be transmitted in one of the following: an RRCSetupComplete message, an RRCResumeComplete message, or an RRCReconfigurationComplete message. The information element may indicate that one or more types of capabilities are restricted. In other words, the information element may notify that certain types of capabilities are restricted (e.g., component carrier (CC) restrictions, bandwidth (BW) restrictions, etc.), but not the actual value of the restriction.

[0072] In some embodiments, the first capability supported in the second service is transmitted in a UECapabilityInformation message. In some examples, the UE transmits an indication of the first capability in response to receiving a UECapabilityEnquiry message from the second network. For example, if the network has received UECapabilityEnquiry, the UE may transmit a list of currently supported first capabilities, such as limited UE capabilities, in the UECapabilityInformation message. A new information element may be used in UECapabilityInformation to carry such first capabilities. Among them, the indication of the first capability includes an indication in the UECapabilityInformation message that the first capability is a subset of the normal UE capability set.

[0073] In another example, the UE may include the normal UE capabilities and the first capabilities in separate entities in the UECapabilityInformation message.In another example, the UE may include the normal UE capabilities and the first capabilities in the same list, for example, the UE may include an indication for each normal UE capability including one of the first capabilities.

[0074] In some embodiments, the UE may transmit the first capability or the second capability in a UEAssistanceInformation message (eg, if configured to do so by the second network).

[0075] In some embodiments, the UE may transmit an indication of the first capability or an indication of the second capability in response to receiving a request to report the first capability or the second capability.For example, the UE may receive a UEInformationRequest message from a second network (eg, a serving cell in network B).

[0076] For example, the UEInformationRequest message may include an indication that the second capability should be reported. Based on the request, the UE may transmit a UEInformationResponse message providing the second capability indication. In some examples, the UEInformationRequest message may include a request to report the first capability. Based on the request, the UE may transmit a UEInformationResponse message providing the first capability.

[0077] In some examples, the indication of the first capability or the second capability transmitted by the UE to the second network may include one or more of the following: the maximum aggregate bandwidth of all downlink and uplink carriers across the first frequency range FR1 and / or the second frequency range FR2 (FR1 defines frequency bands in the sub-6 GHz spectrum (although 7125 MHz may be the maximum), while FR2 defines frequency bands in the millimeter wave spectrum); for the first frequency range FR1 and / or the second frequency range FR2, the maximum number of downlink and uplink secondary cells in the primary cell group and / or the maximum number of downlink and uplink primary and secondary cells in the secondary cell group; The maximum number of receiving Rx chains or panels for the second frequency range FR2; A list of carrier frequencies and / or carrier frequency combinations that need to be released; · Requires updates on the target New Radio (NR) / Evolved UMTS Terrestrial Radio Access (E-UTRA) A list of frequency band combinations that indicates whether the frequency band requires measurement gaps / network controlled small gaps (NCSG); · One or more restricted UE power classes for operation in the second network. The UE may indicate the restricted power class(es) per UE (e.g., applied to all frequency bands), per frequency band (e.g., applied to a specific frequency band), or per frequency band combination (e.g., applied to a specific frequency band combination, such as certain UL CA configurations). The UE power class may define the maximum output power supported by the UE for transmitting signals when operating on a certain frequency band or frequency band combination. Examples of UE power classes are power class 1 (e.g., 31 dBm), power class 1.5 (e.g., 29 dBm), power class 2 (e.g., 26 dBm), power class 3 (e.g., 23 dBm), power class 5 (e.g., 20 dBm), etc. For example, the UE may support and be able to achieve a maximum UE power class 1.5 (29 dBm), and may indicate that its restricted UE power class is power class 3 and / or power class 2 when operating in network B. In another example, the UE may support and be capable of a maximum UE power class 2 (26 dBm) and may indicate that its limited UE power class is power class 3 when operating in network B. Since network A and network B do not collaborate and / or independently schedule the UE, the limitation in the UE power class may enable the UE to meet regulatory requirements related to radiation exposure to humans, such as electromagnetic power density exposure requirements provided by regulatory agencies, such as specific absorption rate (SAR). · Limited maximum uplink duty cycle MUDC. In other words, the UE may indicate a limited maximum uplink duty cycle MUDC. The duty cycle (MUDC) is part of the reduced UE configuration / capability to enable the UE to perform operations in Network B. The MUDC indicates the maximum percentage of time resources (e.g., symbols, time slots, sub - frames) that can be scheduled for uplink transmission during a certain evaluation period (e.g., T1 seconds, such as 1 second) to ensure that the UE meets the exposure requirements specified by the regulatory body (e.g., electromagnetic energy absorption requirements, such as SAR). For example, the UE may support a certain maximum value of MUDC (e.g., X1 percentage). However, for operations in Network B, the UE may indicate to the network node in the assistance information to use a lower (restricted) value of MUDC (e.g., X2 percentage). In one example, X2 < X1. In another example, X1 = 80% and X2 = 50%. In one example, due to the reduced ability / configuration of MUDC when operating in Network B, the UE may be able to use its maximum UE power level (e.g., PC 1.5). In another example, even when using the restricted MUDC for operations in Network B, the UE may indicate to use a restricted UE power level (e.g., PC2 or PC3). · For the restricted MIMO configuration of UE operations in the second network. For example, the UE may indicate that the UE can be configured with a maximum of N MIMO layers for operating signals in Network B. Where N < Nmax; Nmax is the maximum (unrestricted) number of MIMO layers supported by the UE. The parameter N can be the same for uplink and downlink MIMO operations in Network B, or N can be different for uplink MIMO operations and downlink MIMO operations in Network B. For example, N1 is used for the restricted number of UL downlink MIMO layers, and N2 is used for the restricted number of downlink MIMO layers. In one example, N = 2 and Nmax = 4. In another example, N1 = 1 and N2 = 2. The UE may have to restrict the MIMO configuration due to insufficient baseband resources, such as when operating on two networks A and B. · For the restricted receive Rx chain and / or panel of UE operations in the second network. For example, the UE may indicate that the UE can be configured with a maximum of N Rx chains for operating signals in Network B. Where N < Nmax; Nmax is the maximum (unrestricted) number of Rx chains / panels supported by the UE. In one example, N = 2 and Nmax = 4. In another example, N1 = 1 and N2 = 2. The UE may have to restrict the Rx chain configuration due to insufficient beam resources, such as when operating on two networks A and B. ​​· Restricted UE receiver configurations for UE operation in a second network. The UE receiver configuration can be characterized by one or more of the following: the number of receivers or receive antenna ports (Rx), the ability to mitigate or eliminate or minimize in-cell interference and / or inter-cell interference or interfering signals (e.g., interference mitigation receivers such as interference rejection and combining (IRC), interference cancellation receivers, etc.). Examples of interfering signals are reference signals (e.g., CRS) in the serving or interfering cell, signals transmitted by a network node (e.g., a base station (BS)) to other UEs in the serving or interfering cell, MIMO inter-layer or inter-stream interference caused by signals transmitted by the network node to the same UE but on different MIMO / inter-layer signals. o For example, the UE can indicate that the UE can use at most a number M of receivers for receiving signals in Network B. Where M < Mmax; Mmax is the maximum (unrestricted) number of receivers (e.g., receive antenna ports) supported by the UE. In one example, M = 2 and Mmax = 4. In another example, M = 1 and Mmax = 2. The UE may have to restrict the UE receiver configuration due to insufficient baseband resources, e.g., when operating on two networks A and B. o In another example, the UE can indicate that the UE cannot perform interference mitigation for receiving signals in Network B. The indication regarding the restricted UE receiver configuration can also indicate that the UE cannot perform a certain type of interference mitigation, e.g., the UE cannot perform inter-cell interference mitigation but can perform in-cell interference mitigation, the UE cannot perform CRS interference cancellation / mitigation, etc. o In another example, the UE can indicate that the UE can receive signals without restricting the number of receive antennas, but cannot perform interference mitigation for receiving signals in Network B. o In another example, the UE can indicate that the UE can receive signals through a restricted number of receiver antennas, but is able to perform interference mitigation for receiving signals in Network B. · Restricted duplex mode DM for UE operation in a second network. The UE can indicate the restricted DM per UE (e.g., should apply to all frequency bands), per frequency band (e.g., apply to a specific frequency band), or per frequency band combination (e.g., apply to a specific frequency band combination such as a certain UL CA configuration). Examples of duplex modes are: Frequency division duplex (FDD), time division duplex (FDD), half-duplex FDD (HD-FDD), full-duplex (FD), etc. In the FDD operation mode, the transmission of a signal by a device and the reception of a signal by the same device occur on different carrier frequency channels. In the TDD operation mode, the transmission of a signal by a device and the reception of a signal by the same device occur on different time resources on the same carrier frequency channel but do not overlap in time. In the HD-FDD operation mode, the transmission of a signal by a device and the reception of a signal by the same device occur on different carrier frequencies and on different time resources that do not overlap in time. In the FD operation mode, the transmission of a signal by a device and the reception of a signal by the same device occur on the same carrier frequency and on the same time resources. Source period. Some examples of restricted DM indicated by the UE are: o For example, a UE supporting FDD may indicate that it can only operate using HD-FDD in Network B. o In another example, a UE supporting FD may indicate that it can operate using any one or more of HD-FDD, FDD, and TDD in network B. · Restricted processing capability for UE operation in the second network. Examples of restricted processing capability are: Longer processing delay requirements for RRC procedures compared to unrestricted processing capacity; Longer HARQ feedback delay for reception of DL channels (e.g., PDSCH) compared to unrestricted processing capacity; Longer Channel State Indicator (CSI) for reporting CSI results (e.g., Channel Quality Indicator (CQI), Rank Indicator, L1 Reference Signal Received Power (RSRP), Precoding Matrix Indicator (PMI), etc.) compared to unrestricted processing capacity Feedback delay, etc. Limited sidelink (SL) operation in the second network when the UE is operating in the second network. SL operation may Includes the operation (transmission to and / or reception) of signals between at least two UEs on a side link, which is a direct communication link between UEs. Examples of SL operations / communications are V2X, device-to-device (D2D), etc. Limited SL operations may include any one or more of the following: o does not perform any type of SL when operating in Network B, o Do not perform a certain type of SL when operating in Network B, such as not performing SL on shared carriers (between cellular / WAN and SL operations), not performing SL on dedicated carriers (carriers used only in SL operations), not performing SL relay operations (e.g., UE cannot be configured as a SL relay to serve other SL UEs), etc. o Perform SL only on a single carrier when operating in Network B, e.g., do not perform SL CA. o SL is performed only on carriers in the same band when operating in Network B, e.g. no inter-band SLCA. oExecute SL using only a subset of SL operation modes, e.g. • Only broadcast or multicast operation mode is used, ie, broadcast or multicast signals are transmitted and / or received on the SL. ·Use only unicast operation mode, i.e. transmit to and / or receive from another UE in peer-to-peer communication. ·Limited Ultra-Reliable and Low-Latency Communication (URLLC) in the second network when the UE is operating in the second network This enables the UE to use its limited resources to perform and operate enhanced mobile broadband (MBB) operations in Network B. Restricted URLLC operations may include limiting one or more associated URLLC Restricted features may include any one or more of the following: o The UE cannot support PUCCH cell switching. For example, the UE indicates that it cannot switch PUCCH transmission between PCell, PSCell, PUCCH SCell or PUCCH sSCell, etc. o The UE cannot support PUSCH transmissions on a duration below a threshold (e.g. 7 symbols). Restricted measurement capabilities for UE operation in the second network (for NeedForGaps and / or NCSG (network The UE may also use a network controlled small gap (NCSG) capability. A spare radio frequency (RF) chain used for measurements on network A may be made available for network B processing, and the UE may update the band combination status regarding which bands may require measurement gaps or NCSGs for measurements. o When the UE reports support of NeedForGaps in network A and also indicates operation in network B, the information element (IE) NeedForGapsInfoNR indicates whether measurement gaps are required for the UE to perform SSB-based measurements on the NR target band and should be updated. o When the UE reports support for NCSG in network A and also indicates operation in network B, the IENeedForGapNCSG-InfoNR and NeedForGapNCSG-InfoEUTRA indicate whether measurement gaps or NCSG are required for the UE to perform SSB-based measurements on the target band and should be updated. · Restricted enhanced measurement capabilities such as NeedForGaps and / or NCSG capabilities for UE operation in the second network. In other words, enhanced measurement capabilities such as NeedForGaps and / or NCSG capabilities may be restricted when the UE operates in network B. Measurement gaps for network A may be required by default regardless of whether the UE reports the band combination status of NCSG and / or gaps.

[0078] In some examples, the UE may indicate timing information related to or associated with a second capability that is limited in the second service. In other words, when reporting information about any limited capability (e.g., in any of the above examples), the UE may also indicate timing information related to or associated with the limited capability. In one example, the same indicated timing information applies to all limited capabilities. In one example, the indicated timing information applies to one or more groups of limited capabilities. In this (latter) case, separate timing information may be indicated for each group of limited capabilities. For example, the timing information may indicate a time period (Tp) to which the limited capability applies when the UE operates in network B. The UE may also indicate, or it may be predefined (e.g., in the specification), that during times outside the indicated time period (Tp), the UE may operate in network B without any capability restrictions, or the UE may not operate in network B even with capability restrictions, or the UE behavior is undefined with or without capability restrictions (e.g., the UE's operation in network B is undefined or cannot be guaranteed, or it may operate in a best-effort manner, or it may not meet the requirements). The timing information may include one or more of the following timing parameters: o A starting reference time (Ts), e.g., a starting time instance at which the restricted capabilities may apply to UE operation in network B. This may also be a future time, e.g., to allow the UE to complete one or more ongoing tasks, such as post-processing of data received by the UE from a cell in another network (e.g., network B). oThe time period (Tp) during which the restricted capability is applicable. Tp starts at Ts. o End reference time (Te), e.g., the time instance at which the restricted capabilities are no longer applicable to UE operation in network B. In one example, Te = Tr + Ts. oParameters Tr and Te may be expressed in terms of absolute time (such as Coordinated Universal Time (UTC) time), network time, or frame count (e.g., a frame number such as a system frame number (SFN), a superframe number such as H-SFN, a subframe number, a time slot number, a combination of SFN or H-SFN and a time resource number such as a subframe number, etc.) and / or a time resource number (e.g., a subframe number, a time slot number, a symbol number, etc.).

[0079] In some examples, when the second network (e.g., a network node executing method 3) receives an indication that the UE capabilities are limited (via one of the above alternatives), the second network configures the UE using a "basic" configuration, i.e., the UE can be configured only with basic, mandatory supported capabilities.

[0080] In one embodiment, the network node (eg, a serving cell in Network B) waits to receive the first capability or the second capability in a RRCSetupComplete or RRCResumeComplete message from the UE.

[0081] In some examples, the network node in the second network may configure the UE to report the first capability or the second capability via a UEAssistanceInformation message.

[0082] In some examples, the network node retrieves the first capability or the second capability by sending a UEInformationRequest message. The UEInformationRequest message may include an indication of whether the UE should report the first capability or the second capability.

[0083] In some examples, the network node retrieves currently supported capabilities by sending a UEInformationRequest message. The message includes an indication to report currently supported capabilities.

[0084] In some examples, the network node may retrieve the capabilities currently supported by the UE by sending a UECapabilityEnquiry message. The UECapabilityEnquiry message may include an indication reporting the currently supported capabilities.

[0085] In another embodiment, when the network node (e.g., a serving cell in network B) receives the first capability or the second capability (in RRCSetupComplete / RRCResumeComplete, or in UEInformationResponse, or in UEAssistanceInformation), the network node appropriately reconfigures the UE by understanding the current (e.g., limited) UE capabilities.

[0086] The network node (eg, a serving cell in network B) may reconfigure the UE based on the first capability and / or the second capability (eg, the limited UE capability) starting from a reference time (Ts) indicated by the UE. The first capability and / or the second capability may be applicable starting from Ts.

[0087] The network (eg, a serving cell in Network B) may also operate the UE with the first capability and / or the second capability for a duration / time period (Tp). Tp is indicated by the UE over which restrictions apply.

[0088] The network node (eg, a serving cell in network B) may also stop UE operation in network B at or before an end reference time (Te). Te may be indicated by the UE after which one or more restrictions no longer apply.

[0089] In some embodiments, a network node in network B (e.g., network node 1) may exchange first capabilities and / or second capabilities (e.g., restricted UE capabilities) with a second (target) node (network node 2) in network B over an Xn interface, for example, via a HANDOVER REQUEST, an S-NODE ADDITION REQUEST, or a UE Context Information–Retrieve UE Context Response message.

[0090] A non-limiting implementation example is given below: This IE contains the UE capability ID as defined in TS 23.003

[22] .

[0091] In some examples, a network node in network B (e.g., network node 1) notifies a second (target) node in network B (network node 2) that the UE capabilities are limited by sending a flag on the Xn interface, for example, via a HANDOVER REQUEST, S-NODE ADDITION REQUEST, or UE Context Information-Retrieve UE Context Response message. As a result, network node 2 acquires the required UE capabilities.

[0092] The following are non-limiting implementation examples: This IE contains the UE capability ID as defined in TS 23.003

[22] .

[0093] Some embodiments described in this disclosure enable a network (e.g., Figure 1 The network A in the CONNECTED state can confirm the UE capability restriction request from the UE (e.g., the request sent / received in step 6). In addition, the network (e.g., network A) can reconfigure the UE in the CONNECTED state according to the restricted UE capabilities. This restriction of UE capabilities can be temporary (e.g., until a timer expires or a predetermined time period has passed), or the restriction can be until the UE requests to re-enable the capabilities. In other words, the technology described herein includes methods on how to confirm to the UE that the UE configuration will be downgraded (i.e., the UE capabilities are restricted) through network reconfiguration.

[0094] A serving node (e.g., an eNB or gNB) in network A may indicate to the UE that the configuration is based on restricted UE capabilities to enable the UE to perform a connection in / to another network (e.g., network B). In some embodiments, the serving node in network A includes an indication in an RRC message (e.g., an RRCReconfiguration message) that is initiated after the UE requests to restrict its capabilities, and thereby restricts the UE configuration for the M-USIM process. Accordingly, the network confirms to the UE that the restricted capabilities have been accepted / confirmed. In addition, the UE is reconfigured with restricted UE capabilities (i.e., one or more of the UE capabilities that were previously enabled and are now restricted / disabled). For example, in the above Figure 1 In step 6 of , network A may store the received UE assistance information related to the reduced capability for the M-USIM. The restricted configuration is verified and activated by receiving an RRC message (eg, RRCReconfiguration) by the UE.

[0095] In other or further embodiments, when the UE requests to enable full (or more) UE capabilities due to the release of operations in another network (e.g., network B), the serving node in network A may confirm the UE request via an RRC message (e.g., an RRCReconfiguration message). The network may indicate to the UE that the reconfiguration is based on unrestricted (unrestricted) UE capabilities. By doing so, the network confirms to the UE that the request for unrestricted / unrestricted capabilities has been accepted. In addition, the UE is reconfigured with full UE capabilities (or at least previously restricted / disabled UE capabilities). For example, in Figure 1 In step 11 of , following receipt of the request to upgrade UE capabilities and applying network reconfiguration, the UE and network A continue to use full capabilities.

[0096] The following shows a non-limiting implementation of the above embodiment. Specifically, the data structure of the RRCReconfiguration message is shown, wherein the underlined part indicates new fields and elements that can be used to implement the technology. RRCReconfiguration message

[0097] In some embodiments, when the UE connects to network B (while in a connected state in network A), the UE may indicate its limited capabilities to network B. Network B will also confirm the UE limited capabilities by using the mechanism described in the above embodiments to indicate whether to accept the UE request.

[0098] In an alternative embodiment, the network may configure the UE with a separate RestrictedRRCReconfiguration container in an RRC message (e.g., RRCReconfiguration), which contains a downgraded UE configuration affected by the restricted UE capabilities. This container can be a supplement to the configuration based on the full capabilities. In other words, network A may include configurations associated with the full UE capabilities and the restricted UE capabilities, respectively (in separate containers). In this case, the UE should send a confirmation to the network via an RRC message (e.g., an RRCReconfigurationComplete message) indicating which configuration has been selected for use. That is, the confirmation may indicate to the network whether to apply the downgraded configuration associated with the restricted capabilities.

[0099] The following shows a non-limiting implementation of the above alternative embodiments. Specifically, the data structure of the RRCReconfiguration message is shown, wherein the underlined part indicates new fields and elements that can be used to implement the technology. RRCReconfiguration message RRCReconfigurationComplete message

[0146] Fig.10 An example of a communication system 1000 is shown in accordance with some embodiments.

[0147] In this example, the communication system 1000 includes a telecommunications network 1002, which includes an access network 1004 such as a radio access network (RAN) and a core network 1006, which includes one or more core network nodes 1008. The access network 1004 includes one or more access network nodes, such as network nodes 1010a and 1010b (one or more of which may be collectively referred to as network nodes 1010), or any other similar third generation partnership project (3GPP) access node or non-3GPP access point. The network node 1010 facilitates direct or indirect connection of user equipment (UE), such as by connecting UE 1012a, 1012b, 1012c, and 1012d (one or more of which may be collectively referred to as UE 1012) to the core network 1006 over one or more wireless connections.

[0148] Example wireless communications over a wireless connection include transmitting and / or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and / or other types of signals suitable for conveying information without the use of wires, cables, or other material conductors. In addition, in different embodiments, the communication system 1000 may include any number of wired or wireless networks, network nodes, UEs, and / or any other components or systems that can facilitate or participate in the communication of data and / or signals (whether via a wired connection or a wireless connection). The communication system 1000 may include any type of communication network, telecommunication network, data network, cellular network, radio network, and / or other similar types of systems, and / or be connected to them through an interface.

[0149] UE 1012 may be any of a variety of communication devices, including wireless devices that are arranged, configured and / or operable to wirelessly communicate with network node 1010 and other communication devices. Similarly, network node 1010 is arranged, capable, configured and / or operable to communicate directly or indirectly with UE 1012 and / or with other network nodes or devices in telecommunication network 1002 to enable and / or provide network access (such as wireless network access) and / or perform other functions (such as management in telecommunication network 1002).

[0150] In the depicted example, the core network 1006 connects the network node 1010 to one or more hosts, such as the host 1016. These connections may be direct or indirect (via one or more intermediate networks or devices). In other examples, the network node may be directly coupled to the host. The core network 1006 includes one or more core network nodes (e.g., core network node 1008), which are composed of hardware and software components. The features of these components may be substantially similar to those described for the UE, network node and / or host, so that their description is generally applicable to the corresponding components of the core network node 1008. The example core network node includes the functions of one or more of the following items: a mobile switching center (MSC), a mobility management entity (MME), a home subscriber server (HSS), an access and mobility management function (AMF), a session management function (SMF), an authentication server function (AUSF), a subscription identifier cancellation function (SIDF), a unified data management (UDM), a security edge protection agent (SEPP), a network open function (NEF) and / or a user plane function (UPF).

[0151] The host 1016 may be under the ownership or control of, and may be operated by or on behalf of, a service provider other than the operator or provider of the access network 1004 and / or the telecommunications network 1002. The host 1016 may host various applications to provide one or more services, examples of which include providing live and / or pre-recorded audio / video content, data collection services (e.g., retrieving and compiling data about various environmental conditions detected by multiple UEs), analytical functionality, social media, functions for controlling or otherwise interacting with remote devices, functions for an alarm and monitoring center, or any other such functions performed by a server.

[0152] As a whole, Fig.10The communication system 1000 can enable connectivity between UEs, network nodes, and hosts. In that sense, the communication system can be configured to operate according to predefined rules or procedures, such as specific standards, including but not limited to: Global System for Mobile Communications (GSM); Universal Mobile Telecommunications System (UMTS); Long Term Evolution (LTE), and / or other suitable 2G, 3G, 4G, 5G standards or any applicable future generation standards (e.g., 6G); Wireless Local Area Network (WLAN) standards, such as the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard (WiFi); and / or any other suitable wireless communication standards, such as Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave, Near Field Communication (NFC) ZigBee, LiFi and / or any Low Power Wide Area Network (LPWAN) standards, such as LoRa and Sigfox.

[0153] In some examples, the telecommunication network 1002 is a cellular network implementing 3GPP standardized features. Therefore, the telecommunication network 1002 can support network slicing to provide different logical networks to different devices connected to the telecommunication network 1002. For example, the telecommunication network 1002 can provide ultra-reliable low-latency communication (URLLC) services to some UEs, while providing enhanced mobile broadband (eMBB) services to other UEs, and / or provide massive machine type communication (mMTC) / massive IoT services to yet other UEs.

[0154] In some examples, UE 1012 is configured to transmit and / or receive information without direct human interaction. For example, the UE may be designed to transmit information to access network 1004 according to a predetermined schedule when triggered by an internal or external event, or in response to a request from access network 1004. In addition, the UE may be configured to operate in a single RAT or multi-RAT or multi-standard mode. For example, the UE may operate using any one or a combination of Wi-Fi, NR (new air interface), and LTE, i.e., configured for multi-radio dual connectivity (MR-DC), such as E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) new air interface-dual connectivity (EN-DC).

[0155] exist Fig.10In the example shown in , hub 1014 communicates with access network 1004 to facilitate indirect communication between one or more UEs (e.g., UE 1012c and / or 1012d) and a network node (e.g., network node 1010b). In some examples, hub 1014 may be, for example, a controller, a router, a content source, and an analytics node, or any other communication device described herein with respect to a UE. For example, hub 1014 may be a broadband router that enables UE access to core network 1006. As another example, hub 1014 may be a controller that sends commands or instructions to one or more actuators in a UE. The command or instruction may be received from a UE, from a network node 1010, or through an executable code, script, process, or other instruction in hub 1014. As another example, hub 1014 may be a data collector that acts as a temporary storage device for UE data, and in some embodiments, may perform analysis or other processing of the data. As another example, hub 1014 may be a content source. For example, for a UE that is a VR headset, display, speaker, or other media delivery device, the hub 1014 can retrieve VR assets, video, audio, or other media or data related to sensory information via a network node, and then the hub 1014 provides these contents directly to the UE after performing local processing, and / or after adding additional local content. In yet another example, the hub 1014 acts as a proxy server or orchestrator for the UE, especially when one or more of the UEs are low-energy IoT devices.

[0156] The hub 1014 may have a constant / persistent or intermittent connection to the network node 1010b. The hub 1014 may also allow different communication schemes and / or scheduling between the hub 1014 and the UE (e.g., UE 1012c and / or 1012d) and between the hub 1014 and the core network 1006. In other examples, the hub 1014 is connected to the core network 1006 and / or one or more UEs via a wired connection. In addition, the hub 1014 may be configured to connect to an M2M service provider through the access network 1004 and / or to another UE via a direct connection. In some cases, the UE may establish a wireless connection with the network node 1010 while still being connected via the hub 1014 via a wired or wireless connection. In some embodiments, the hub 1014 may be a dedicated hub - that is, a hub whose primary function is to route communications to / from the UE from / to the network node 1010b. In other embodiments, hub 1014 may be a non-dedicated hub - ie, a device operable to route communications between UEs and network node 1010b, but otherwise capable of operating as a communications start and / or end point for certain data channels.

[0157] Fig.11 UE 1100 according to some embodiments is shown. As used herein, UE refers to a device capable of, configured, arranged and / or operable to wirelessly communicate with a network node and / or other UE. Examples of UE include, but are not limited to, smart phones, mobile phones, cellular phones, voice over IP (VoIP) phones, wireless local loop phones, desktop computers, personal digital assistants (PDAs), wireless cameras, game consoles or devices, music storage devices, playback devices, wearable terminal devices, wireless endpoints, mobile stations, tablet computers, laptop computers, laptop embedded devices (LEEs), laptop mounted devices (LMEs), smart devices, wireless customer premises equipment (CPEs), vehicle mounted or vehicle embedded / integrated wireless devices, etc. Other examples include any UE identified by the 3rd Generation Partnership Project (3GPP), including narrowband Internet of Things (NB-IoT) UEs, machine type communications (MTC) UEs, and / or enhanced MTC (eMTC) UEs.

[0158] The UE may support device-to-device (D2D) communications, such as by implementing 3GPP standards for sidelink communications, dedicated short-range communications (DSRC), vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), or vehicle-to-everything (V2X). In other examples, a UE may not necessarily have a user in the sense of a human user who owns and / or operates an associated device. Rather, a UE may represent a device that is intended to be sold to or operated by a human user, but may not be, or may not initially be, associated with a particular human user (e.g., a smart sprinkler controller). Alternatively, a UE may represent a device that is not intended to be sold to or operated by an end user, but may be associated with or operated for the benefit of a user (e.g., a smart power meter).

[0159] UE 1100 includes processing circuitry 1102, which is operatively coupled to input / output interface 1106, power source 1108, memory 1110, communication interface 1112, and / or any other components or any combination thereof via bus 1104. A particular UE may utilize Fig.11 All or a subset of the components shown in . The level of integration between components may vary from one UE to another UE. In addition, a particular UE may include multiple instances of a component, such as multiple processors, memories, transceivers, transmitters, receivers, etc.

[0160] The processing circuit 1102 is configured to process instructions and data, and may be configured to implement any sequential state machine operable to execute instructions stored in the memory 1110 as a machine-readable computer program. The processing circuit 1102 may be implemented as one or more hardware-implemented state machines (e.g., in discrete logic, a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), etc.); programmable logic together with appropriate firmware; one or more stored computer programs, general-purpose processors (such as a microprocessor or a digital signal processor (DSP)), together with appropriate software; or any combination of the foregoing. For example, the processing circuit 1102 may include multiple central processing units (CPUs). The processing circuit 1102 may be operable to provide UE 1100 functionality alone or in combination with other UE 1100 components (such as the memory 1110). For example, the processing circuit 1102 may be configured to cause the UE 1102 to perform as described in reference Figure 2 , Figure 4 , Figure 5 or Figure 6 The method described.

[0161] In this example, the input / output interface 1106 can be configured to provide one or more interfaces to an input device, an output device, or one or more input and / or output devices. Examples of output devices include speakers, sound cards, video cards, displays, monitors, printers, actuators, transmitters, smart cards, another output device, or any combination thereof. An input device can allow a user to capture information into the UE 1100. Examples of input devices include touch-sensitive or presence-sensitive displays, cameras (e.g., digital cameras, digital video cameras, web cameras, etc.), microphones, sensors, mice, trackballs, direction pads, trackpads, rollers, smart cards, and the like. A presence-sensitive display can include a capacitive or resistive touch sensor to sense input from a user. The sensor can be, for example, an accelerometer, a gyroscope, a tilt sensor, a force sensor, a magnetometer, an optical sensor, a proximity sensor, a biometric sensor, or the like, or any combination thereof. An output device can use the same type of interface port as an input device. For example, a universal serial bus (USB) port can be used to provide an input device and an output device.

[0162] In some embodiments, the power source 1108 may be configured as a battery or a battery pack. Other types of power sources may be used, such as an external power source (e.g., a power socket), a photovoltaic device, or a power unit. The power source 1108 may also include a power supply circuit for delivering power from the power source 1108 itself and / or an external power source to various parts of the UE 1100 via an input circuit or an interface such as a power cable. For example, the delivered power may be used to charge the power source 1108. The power supply circuit may perform any formatting, conversion, or other modification to the power from the power source 1108 so that the power is suitable for the corresponding components of the UE 1100 to which the power is supplied.

[0163] The memory 1110 may be configured to include a memory such as a random access memory (RAM), a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a magnetic disk, an optical disk, a hard disk, a removable cassette, a flash drive, etc. In one example, the memory 1110 includes one or more application programs 1114 (such as an operating system, a web browser application, a widget, a gadget engine, or other application) and corresponding data 1116. The memory 1110 may store any of a variety of operating systems or a combination of operating systems for use by the UE 1100.

[0164] The memory 1110 may be configured to include a plurality of physical drive units, such as a redundant array of independent disks (RAID), a flash memory, a USB flash drive, an external hard drive, a thumb drive, a pen drive, a key drive, a high-density digital versatile disk (HD-DVD) optical drive, an internal hard drive, a Blu-ray optical drive, a holographic digital data storage (HDDS) optical drive, an external micro dual in-line memory module (DIMM), a synchronous dynamic random access memory (SDRAM), an external micro DIMM SDRAM, a smart card memory (such as a tamper-proof module in the form of a universal integrated circuit card (UICC), including one or more subscriber identity modules (SIMs), such as USIM and / or ISIM), other memories, or any combination thereof. The UICC may be, for example, an embedded UICC (eUICC), an integrated UICC (iUICC), or a removable UICC commonly referred to as a “SIM card”. The memory 1110 may allow the UE 1100 to access instructions, applications, and the like stored on a transient or non-transitory storage medium to offload data or upload data. An article of manufacture, such as an article of manufacture utilizing a communication system, may be tangibly embodied as or in memory 1110 , which may be or may include a device-readable storage medium.

[0165] The processing circuit 1102 may be configured to communicate with an access network or other network using a communication interface 1112. The communication interface 1112 may include one or more communication subsystems and may include or be communicatively coupled to an antenna 1122. The communication interface 1112 may include one or more transceivers for communication, such as by communicating with one or more remote transceivers of another device capable of wireless communication (e.g., another UE or a network node in an access network). Each transceiver may include a transmitter 1118 and / or a receiver 1120 suitable for providing network communications (e.g., optical, electrical, frequency allocation, etc.). In addition, the transmitter 1118 and the receiver 1120 may be coupled to one or more antennas (e.g., antenna 1122) and may share circuit components, software, or firmware, or alternatively be implemented separately.

[0166] In some embodiments, the communication functionality of the communication interface 1112 may include cellular communication, Wi-Fi communication, LPWAN communication, data communication, voice communication, multimedia communication, short-range communication such as Bluetooth, near field communication, location-based communication such as using a global positioning system (GPS) to determine location, another similar communication functionality, or any combination thereof. Communication may be implemented according to one or more communication protocols and / or standards, such as IEEE 802.11, code division multiple access (CDMA), wideband code division multiple access (WCDMA), GSM, LTE, new radio (NR), UMTS, WiMax, Ethernet, transmission control protocol / Internet protocol (TCP / IP), synchronous optical networking (SONET), asynchronous transfer mode (ATM), QUIC, hypertext transfer protocol (HTTP), etc.

[0167] Regardless of the type of sensor, the UE may provide an output of the data captured by its sensor via a wireless connection to a network node through its communication interface 1112. The data captured by the UE's sensor may be delivered to the network node via another UE via a wireless connection. The output may be periodic (e.g., every 15 minutes if it reports the sensed temperature), random (e.g., to even out the load of reports from several sensors), in response to a trigger event (e.g., when moisture is detected, an alarm is sent), in response to a request (e.g., a user initiated request), or a continuous stream (e.g., a live video feed of a patient).

[0168] As another example, the UE includes an actuator, motor, or switch associated with a communication interface configured to receive wireless input from a network node via a wireless connection. In response to the received wireless input, the state of the actuator, motor, or switch can change. For example, the UE can include a motor that adjusts a control surface or rotor of a drone in flight based on the received input, or controls a robotic arm that performs a medical procedure based on the received input.

[0169] A UE, when in the form of an Internet of Things (IoT) device, may be a device for use in one or more application areas, including but not limited to urban wearable technology, extended industrial applications, and healthcare. Non-limiting examples of such IoT devices are devices that are or are embedded in the following devices: a connected refrigerator or freezer, a TV, a connected lighting device, an electric meter, a robotic vacuum cleaner, a voice-controlled smart speaker, a home security camera, a motion detector, a thermostat, a smoke detector, a door / window sensor, a flood / humidity sensor, an electric door lock, a connected doorbell, an air conditioning system such as a heat pump, an autonomous vehicle, a monitoring system, a weather monitoring device, a vehicle parking monitoring device, an electric vehicle charging station, a smart watch, a fitness tracker, a head-mounted display for augmented reality (AR) or virtual reality (VR), a wearable device for tactile enhancement or sensory enhancement, a sprinkler, an animal or item tracking device, a sensor for monitoring plants or animals, an industrial robot, an unmanned aerial vehicle (UAV), and any type of medical device, such as a heart rate monitor or a teleoperated surgical robot. In addition to the above, Fig.11 In addition to the other components described for UE 1100 shown in FIG. 1 , a UE in the form of an IoT device may include circuits and / or software depending on the intended application of the IoT device.

[0170] As yet another specific example, in an IoT scenario, a UE may represent a machine or other device that performs monitoring and / or measurement and transmits the results of such monitoring and / or measurement to another UE and / or a network node. In this case, the UE may be an M2M device, which may be referred to as an MTC device in the 3GPP context. As a specific example, a UE may implement the 3GPP NB-IoT standard. In other scenarios, a UE may represent a vehicle (such as a car, bus, truck, ship, and airplane) or other device that is capable of monitoring and / or reporting its operating status or other functions associated with its operation.

[0171] In fact, any number of UEs may be used together for a single use case. For example, a first UE may be or be integrated into a drone and provide the drone's speed information (obtained via a speed sensor) to a second UE that is a remote controller operating the drone. When the user makes changes from the remote controller, the first UE may adjust the throttle on the drone (e.g., by controlling an actuator) to increase or decrease the drone's speed. The first and / or second UE may also include more than one of the above functionalities. For example, a UE may include a sensor and an actuator and handle data communications for both the speed sensor and the actuator.

[0172] Fig.12 A network node 1200 according to some embodiments is shown. As used herein, a network node refers to a device capable, configured, arranged and / or operable to communicate directly or indirectly with a UE and / or with other network nodes or devices in a telecommunications network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs), and NR Node Bs (gNBs)).

[0173] Base stations may be classified based on the amount of coverage they provide (or, in other words, their transmit power level), and therefore, depending on the amount of coverage provided, may be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node that controls a relay. A network node may also include one or more (or all) parts of a distributed radio base station, such as a centralized digital unit and / or a remote radio unit (RRU), sometimes referred to as a remote radio head (RRH). Such a remote radio unit may be integrated with an antenna or may be an antenna-integrated radio device without being integrated with an antenna. Portions of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS).

[0174] Other examples of network nodes include a multi-transmission point (multi-TRP) 5G access node, a multi-standard radio (MSR) device such as an MSR BS, a network controller such as a radio network controller (RNC) or a base station controller (BSC), a base transceiver station (BTS), a transmission point, a transmission node, a multi-cell / multicast coordination entity (MCE), an operation and maintenance (O&M) node, an operation support system (OSS) node, a self-organizing network (SON) node, a positioning node (e.g., an evolved serving mobile location center (E-SMLC)) and / or a minimization of drive tests (MDT).

[0175] The network node 1200 includes a processing circuit 1202, a memory 1204, a communication interface 1206 and a power source 1208, and / or any other components, or any combination thereof. The network node 1200 may be composed of multiple physically separate components (e.g., a Node B component and an RNC component, or a BTS component and a BSC component, etc.), each of which may have its own corresponding components. In the specific case where the network node 1200 includes multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared between several network nodes. For example, a single RNC may control multiple Node Bs. In such scenarios, in some instances, each unique Node B and RNC pair may be considered to be a single separate network node. In some embodiments, the network node 1200 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be replicated (e.g., separate memories 1204 for different RATs), and some components may be reused (e.g., the same antenna 1210 may be shared by different RATs). The network node 1200 may also include multiple sets of the various illustrated components for different wireless technologies, such as GSM, WCDMA, LTE, NR, WiFi, Zigbee, Z-Wave, LoRaWAN, Radio Frequency Identification (RFID), or Bluetooth wireless technologies, integrated into the network node 1200. These wireless technologies may be integrated into the same or different chips or chipsets and other components within the network node 1200.

[0176] The processing circuit 1202 may include a combination of one or more of the following: a microprocessor, a controller, a microcontroller, a central processing unit, a digital signal processor, an application specific integrated circuit, a field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software, and / or encoded logic operable to provide network node 1200 functionality alone or in combination with other network node 1200 components such as the memory 1204. For example, the processing circuit 1202 may be configured to cause the network node to perform as described in reference Figure 3 , Figure 7 , Figure 8 or Fig. 9 The method described.

[0177] In some embodiments, processing circuitry 1202 includes a system on a chip (SOC). In some embodiments, processing circuitry 1202 includes one or more of radio frequency (RF) transceiver circuitry 1212 and baseband processing circuitry 1214. In some embodiments, radio frequency (RF) transceiver circuitry 1212 and baseband processing circuitry 1214 may be on separate chips (or chipsets), boards, or units, such as a radio unit and a digital unit. In alternative embodiments, part or all of RF transceiver circuitry 1212 and baseband processing circuitry 1214 may be on the same chip or chipset, board, or unit.

[0178] The memory 1204 may include any form of volatile or non-volatile computer-readable memory, including but not limited to permanent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (e.g., hard disk), removable storage media (e.g., flash drive, compact disk (CD) or digital video disk (DVD)), and / or any other volatile or non-volatile, non-transitory device readable and / or computer executable memory device that stores information, data and / or instructions that can be used by the processing circuit 1202. The memory 1204 may store any suitable instructions, data or information, including computer programs, software, applications (including one or more of logic, rules, codes, tables, etc.) and / or other instructions (capable of being executed by the processing circuit 1202 and utilized by the network node 1200). The memory 1204 may be used to store any calculations performed by the processing circuit 1202 and / or any data received via the communication interface 1206. In some embodiments, the processing circuit 1202 and the memory 1204 are integrated.

[0179] The communication interface 1206 is used for wired or wireless communication of signaling and / or data between network nodes, access networks and / or UEs. As shown, the communication interface 1206 includes (one or more) ports / (one or more) terminals 1216, for example, to send data to the network and receive data from it via a wired connection. The communication interface 1206 also includes a radio front-end circuit 1218, which can be coupled to the antenna 1210 or is a part of the antenna 1210 in some embodiments. The radio front-end circuit 1218 includes a filter 1220 and an amplifier 1222. The radio front-end circuit 1218 can be connected to the antenna 1210 and the processing circuit 1202. The radio front-end circuit can be configured to adjust the signal transmitted between the antenna 1210 and the processing circuit 1202. The radio front-end circuit 1218 can receive digital data to be sent to other network nodes or UEs via a wireless connection. The radio front-end circuit 1218 can use a combination of a filter 1220 and / or an amplifier 1222 to convert the digital data into a radio signal with appropriate channel and bandwidth parameters. The radio signals may then be transmitted via antenna 1210. Similarly, when receiving data, antenna 1210 may collect the radio signals, which are then converted into digital data by radio front end circuit 1218. The digital data may be passed to processing circuit 1202. In other embodiments, the communication interface may include different components and / or different combinations of components.

[0180] In certain alternative embodiments, the network node 1200 does not include a separate radio front end circuit 1218, instead the processing circuit 1202 includes the radio front end circuit and is connected to the antenna 1210. Similarly, in some embodiments, all or part of the RF transceiver circuit 1212 is part of the communication interface 1206. In still other embodiments, the communication interface 1206 includes one or more ports or terminals 1216, the radio front end circuit 1218, and the RF transceiver circuit 1212 as part of a radio unit (not shown), and the communication interface 1206 communicates with the baseband processing circuit 1214 as part of a digital unit (not shown).

[0181] Antenna 1210 may include one or more antennas or antenna arrays configured to send and / or receive wireless signals. Antenna 1210 may be coupled to radio front end circuit 1218 and may be any type of antenna capable of wirelessly transmitting and receiving data and / or signals. In some embodiments, antenna 1210 may be separate from network node 1200 and may be connected to network node 1200 via an interface or port.

[0182] Antenna 1210, communication interface 1206 and / or processing circuit 1202 can be configured to perform any receiving operation and / or certain obtaining operation described herein as being performed by a network node. Any information, data and / or signal can be received from a UE, another network node and / or any other network device. Similarly, antenna 1210, communication interface 1206 and / or processing circuit 1202 can be configured to perform any transmitting operation described herein as being performed by a network node. Any information, data and / or signal can be transmitted to a UE, another network node and / or any other network device.

[0183] The power source 1208 provides power to the various components of the network node 1200 in a form suitable for the respective components (e.g., at the voltage and current levels required by each respective component). The power source 1208 may also include or be coupled to a power management circuit to provide power to the components of the network node 1200 for performing the functionality described herein. For example, the network node 1200 may be connectable to an external power source (e.g., a power grid, a power outlet) via an input circuit or interface such as a cable, whereby the external power source supplies power to the power supply circuit of the power source 1208. As another example, the power source 1208 may include a power source in the form of a battery or battery pack that is connected to or integrated in the power supply circuit. The battery may provide backup power in the event of a failure of the external power source.

[0184] An embodiment of the network node 1200 may include Fig.12 , which are used to provide certain aspects of the functionality of the network node, including any functionality described herein and / or any functionality necessary to support the subject matter described herein. For example, the network node 1200 may include a user interface device to allow information to be input into the network node 1200 and to allow information to be output from the network node 1200. This may allow a user to perform diagnostic, maintenance, repair, and other management functions for the network node 1200.

[0185] Fig.13 is a block diagram of a host 1300 according to various aspects described herein, and the host 1300 may be Fig.10 1016 of the embodiment of the host. As used herein, the host 1300 can be or include various combinations of hardware and / or software, including processing resources in a stand-alone server, a blade server, a cloud-enabled server, a distributed server, a virtual machine, a container, or a server farm. The host 1300 can provide one or more services to one or more UEs.

[0186] Host 1300 includes processing circuitry 1302, which is operably coupled to input / output interface 1306, network interface 1308, power source 1310, and memory 1312 via bus 1304. Other components may be included in other embodiments. The features of these components may be substantially similar to those described with respect to previous figures (such as Fig.11 and Fig.12 ) so that its description is generally applicable to the corresponding components of the host 1300.

[0187] The memory 1312 may include one or more computer programs, including one or more host applications 1314 and data 1316, which may include user data, such as data generated by the UE for the host 1300 or data generated by the host 1300 for the UE. Embodiments of the host 1300 may utilize only a subset or all of the components shown. The host application 1314 may be implemented in a container-based architecture and may provide support for video codecs (e.g., Versatile Video Coding (VVC), High Efficiency Video Coding (HEVC), Advanced Video Coding (AVC), MPEG, VP9) and audio codecs (e.g., FLAC, Advanced Audio Coding (AAC), MPEG, and g.711), including transcoding for multiple different categories, types, or implementations of UEs (e.g., mobile phones, desktop computers, wearable display systems, heads-up display systems). The host application 1314 may also provide user authentication and permission checks, and may periodically report health, routing, and content availability to a central node (such as a device in or on the edge of a core network). Thus, the host 1300 can select and / or indicate a different host for an over-the-top service for the UE. The host application 1314 can support various protocols, such as HTTP Live Streaming (HLS) protocol, Real-time Messaging Protocol (RTMP), Real-time Streaming Protocol (RTSP), Dynamic Adaptive Streaming over HTTP (MPEG-DASH), etc.

[0188] Fig.141400 is a block diagram showing a virtualized environment 1400 in which the functions implemented by some embodiments can be virtualized. In this context, virtualization means creating a virtual version of a device or apparatus, which may include a virtualized hardware platform, storage device, and networking resources. As used herein, virtualization may be applied to any apparatus described herein or its components, and relates to an implementation in which at least a portion of functionality is implemented as one or more virtual components. Some or all of the functions described herein may be implemented as virtual components executed by one or more virtual machines (VMs), which are implemented in one or more virtual environments 1400 hosted by one or more hardware nodes, which are hardware computing devices such as those operated as network nodes, UEs, core network nodes, or hosts. In addition, in embodiments where a virtual node does not require radio connectivity (e.g., a core network node or host), the node may be fully virtualized.

[0189] Application 1402 (which may alternatively be referred to as a software instance, a virtual appliance, a network function, a virtual node, a virtual network function, etc.) runs in a virtualized environment Q400 to implement some features, functions and / or benefits of some embodiments disclosed herein.

[0190] The hardware 1404 includes processing circuitry, memory storing software and / or instructions executable by the hardware processing circuitry, and / or other hardware devices as described herein, such as network interfaces, input / output interfaces, and the like. The software may be executed by the processing circuitry to instantiate one or more virtualization layers 1406 (also referred to as hypervisors or virtual machine monitors (VMMs)), provide VMs 1408a and 1408b (one or more of which may be collectively referred to as VMs 1408), and / or perform any of the functions, features, and / or benefits described with respect to some embodiments described herein. The virtualization layer 1406 may present a virtual operating platform that appears to be networked hardware to the VMs 1408.

[0191] The VM 1408 includes virtual processing, virtual memory, virtual networking or interfaces, and virtual storage, and may be run by a corresponding virtualization layer 1406. Different embodiments of instances of virtual devices 1402 may be implemented on one or more of the VMs 1408, and the implementation may be performed in different ways. Virtualization of hardware is referred to as network function virtualization (NFV) in some contexts. NFV may be used to integrate many network device types onto industry-standard high-capacity server hardware, physical switches, and physical storage (which may be located in data centers as well as customer premises equipment).

[0192] In the context of NFV, VMs 1408 can be software implementations of physical machines that run programs as if they were executing on physical, non-virtualized machines. Each of VMs 1408 and the portion of hardware 1404 on which the VM executes (whether hardware dedicated to the VM and / or hardware shared by the VM with other VMs) forms a separate virtual network element. Still in the context of NFV, a virtual network function is responsible for handling a specific network function running in one or more VMs 1408 on top of hardware 1404 and corresponds to an application 1402.

[0193] Hardware 1404 may be implemented in a standalone network node with general or specialized components. Hardware 1404 may implement some functions via virtualization. Alternatively, hardware 1404 may be part of a larger hardware cluster (e.g., such as in a data center or CPE), where many hardware nodes work together and are managed via management and orchestration 1410, which oversees the lifecycle management of application 1402 in addition to other operations. In some embodiments, hardware 1404 is coupled to one or more radio units, each of which includes one or more transmitters and one or more receivers that may be coupled to one or more antennas. The radio unit may communicate directly with other hardware nodes via one or more appropriate network interfaces, and may be used in conjunction with virtual components to provide a virtual node with radio capabilities, such as a radio access node or base station. In some embodiments, some signaling may be provided by using a control system 1412, which may alternatively be used for communication between hardware nodes and radio units.

[0194] Fig.15 A communication diagram showing a host 1502 communicating with a UE 1506 via a network node 1504 over a partially wireless connection according to some embodiments. Fig.15 Describe the UE discussed in the previous paragraphs (such as Fig.10 UE 1012a and / or Fig.11 UE 1100), network nodes (such as Fig.10 The network node 1010a and / or Fig.12 network nodes 1200) and hosts (such as Fig.10 Host 1016 and / or Fig.13 Host 1500) according to various embodiments of the example implementation.

[0195] Similar to the host 1300, an embodiment of the host 1502 includes hardware, such as a communication interface, a processing circuit, and a memory. The host 1502 also includes software that is stored in or accessible by the host 1502 and can be executed by the processing circuit. The software includes a host application that is operable to provide services to a remote user, such as a UE 1506 connected via an over-the-top (OTT) connection 1550 extending between the UE 1506 and the host 1502. When providing services to the remote user, the host application can provide user data transmitted using the OTT connection 1550.

[0196] The network node 1504 includes hardware that enables it to communicate with the host 1502 and the UE 1506. The connection 1560 can be direct or through a core network (such as Fig.10 The core network 1006 of the present invention) and / or one or more other intermediate networks, such as one or more public, private or managed networks. For example, the intermediate network can be a backbone network or the Internet.

[0197] UE 1506 includes hardware and software, which is stored in or accessible by UE 1506 and can be executed by UE processing circuitry. The software includes a client application, such as a web browser or an operator-specific "app", which is operable to provide services to human or non-human users via UE 1506 with the support of host 1502. In host 1502, the executed host application can communicate with the executed client application via an OTT connection 1550 terminated at UE 1506 and host 1502. When providing services to the user, the client application of the UE can receive request data from the host application of the host and provide user data in response to the request data. The OTT connection 1550 can transmit the request data and the user data. The client application of the UE can interact with the user to generate user data, which it provides to the host application via the OTT connection 1550.

[0198] The OTT connection 1550 may extend via a connection 1560 between the host 1502 and the network node 1504 and via a wireless connection 1570 between the network node 1504 and the UE 1506 to provide connectivity between the host 1502 and the UE 1506. The connection 1560 and the wireless connection 1570 over which the OTT connection 1550 may be provided have been drawn abstractly to illustrate communications between the host 1502 and the UE 1506 via the network node 1504 without explicit reference to any intermediate devices and the precise routing of messages via those devices.

[0199] As an example of transmitting data via the OTT connection 1550, in step 1508, the host 1502 provides user data, which can be performed by executing a host application. In some embodiments, the user data is associated with a specific human user interacting with the UE 1506. In other embodiments, the user data is associated with the UE 1506, which shares data with the host 1502 without explicit human interaction. In step 1510, the host 1502 initiates a transmission carrying the user data to the UE 1506. The host 1502 may initiate the transmission in response to a request transmitted by the UE 1506. The request may be caused by human interaction with the UE 1506, or by the operation of a client application executed on the UE 1506. According to the teachings of the embodiments described throughout the present disclosure, the transmission may be delivered via the network node 1504. Therefore, in step 1512, according to the teachings of the embodiments described throughout the present disclosure, the network node 1504 transmits the user data carried in the transmission initiated by the host 1502 to the UE 1506. In step 1514 , UE 1506 receives the user data carried in the transmission, which may be performed by a client application executing on UE 1506 associated with a host application executed by host 1502 .

[0200] In some examples, UE 1506 executes a client application that provides user data to host 1502. The user data may be provided as a reaction or response to data received from host 1502. Therefore, in step 1516, UE 1506 may provide the user data, which may be performed by executing the client application. In providing the user data, the client application may also take into account user input received from the user via the input / output interface of UE 1506. Regardless of the specific manner in which the user data is provided, in step 1518, UE 1506 initiates transmission of the user data to host 1502 via network node 1504. In step 1520, in accordance with the teachings of the embodiments described throughout the present disclosure, network node 1504 receives the user data from UE 1506 and initiates transmission of the received user data to host 1502. In step 1522, host 1502 receives the user data carried in the transmission initiated by UE 1506.

[0201] One or more of the various embodiments use OTT connection 1550 to improve the performance of OTT services provided to UE 1506, with wireless connection 1570 forming the final segment. More specifically, the teachings of these embodiments can improve the configuration of UEs and thereby provide benefits such as improved UE performance.

[0202] In an example scenario, plant status information can be collected and analyzed by host 1502. As another example, host 1502 can process audio and video data that has been obtained from UE for creating a map. As another example, host 1502 can collect and analyze real-time data to help control traffic congestion (e.g., control traffic lights). As another example, host 1502 can store surveillance videos uploaded by UE. As another example, host 1502 can store or control access to media content, such as video, audio, VR or AR that it can broadcast, multicast or unicast to UE. As other examples, host 1502 can be used for energy pricing, remote control of non-time-critical electrical loads to balance power generation needs, location services, presentation services (such as compiled maps based on data collected from remote devices, etc.), or any other function of collecting, retrieving, storing, analyzing and / or transmitting data.

[0203] In some examples, a measurement process may be provided for the purpose of monitoring data rates, latency, and other factors improved by one or more embodiments. There may also be optional network functionality for reconfiguring the OTT connection 1550 between the host 1502 and the UE 1506 in response to changes in the measurement results. The measurement process and / or network functionality for reconfiguring the OTT connection may be implemented in the software and hardware of the host 1502 and / or in the software and hardware of the UE 1506. In an embodiment, a sensor (not shown) may be deployed in or associated with other devices through which the OTT connection 1550 passes; the sensor may participate in the measurement process by providing the values ​​of the monitored quantities exemplified above or providing the values ​​of other physical quantities from which the software can calculate or estimate the monitored quantities. The reconfiguration of the OTT connection 1550 may include message formats, retransmission settings, preferred routes, etc.; the reconfiguration does not require direct changes to the operation of the network node 1504. Such processes and functionality may be known and practiced in the art. In certain embodiments, the measurements may involve dedicated UE signaling that facilitates measurements of throughput, propagation time, latency, and the like by the host 1502. Such measurements are possible because software causes messages (particularly empty or "dummy" messages) to be transmitted using the OTT connection 1550 while monitoring propagation time, errors, etc.

[0204] Although the computing devices (e.g., UE, network node, host) described herein may include a combination of the hardware components shown, other examples may include computing devices with different combinations of components. It should be understood that these computing devices may include any appropriate combination of hardware and / or software required to perform the tasks, features, functions, and methods disclosed herein. The determination, calculation, acquisition, or similar operations described herein may be performed by a processing circuit, which may process information by, for example, the following operations: converting the obtained information into other information, comparing the obtained information or the converted information with the information stored in the network node, and / or performing one or more operations based on the obtained information or the converted information, and making a determination as a result of the processing. In addition, although the components are depicted as being located within a larger box or nested within multiple boxes, in reality, the computing device may include multiple different physical components constituting a single illustrated component, and functionality may be divided between separate components. For example, a communication interface may be configured to include any component described herein, and / or the functionality of the component may be divided between a processing circuit and a communication interface. In another example, the non-computationally intensive functions of any such component may be implemented in software or firmware, and the computationally intensive functions may be implemented in hardware.

[0205] In certain embodiments, some or all of the functions described herein may be provided by a processing circuit that executes instructions stored in a memory, which in certain embodiments may be a computer program product in the form of a non-transitory computer-readable storage medium. In alternative embodiments, some or all of the functionality may be provided by a processing circuit without executing instructions stored on a separate or discrete device-readable storage medium, such as in a hardwired manner. In any of those specific embodiments, the processing circuit may be configured to perform the described functionality, regardless of whether instructions stored on a non-transitory computer-readable storage medium are executed. The benefits provided by such functionality are not limited to separate processing circuits or other components of a computing device, but are enjoyed by the computing device as a whole and / or generally by end users and wireless networks.
