Thus, in order to avoid inconsistent network performance, the network operator may set a high, static access threshold to the user devices (particularly the mobile devices that have high mobility) to prevent excessive and frequent network switching.

[0023] As described above, in a non- standalone (NSA) architecture, a 5G network may be deployed on the existing LTE infrastructure. Accordingly, there are situations where both the 5G network and the LTE network are available at a certain telecommunication network grid.
Nevertheless, the adoption rate of the 5G network remains low, regardless of the fact that the number of 5G roll-outs has increased significantly. [0024] FIG. 1 illustrates a graph of comparison between the trend of LTE traffic, 5G traffic, and 5G traffic share in the related art. As illustrated in FIG. 1, the rate of traffic growth of the 5G is abysmally low (indicating the low adoption rate of the 5G network). Specifically, despite the network operator have spent significant operating expenses (OPEX) and capital expenditures (CAPEX) on rolling out the 5G infrastructure and the number of available 5G infrastructure has increased, the majority of the network traffic is still constituted by the LTE traffic.
[0025] The low adaption rate of the 5G network may be caused by several reasons. Referring to FIG. 2, which illustrates a table that presents possible configurations of a network and a user device in the related art. In this example, it is assumed that the user device has an active 5G subscription and the user device is capable of connecting to the 5G network.
[0026] As illustrated in the first row of the table in FIG. 2, under normal circumstances, the network that supports E-UTRAN New Radio Dual Connectivity (ENDC), which is the feature that enables the user device to utilize the connections to both LTE and 5G networks, has enabled the ENDC. Similarly, the user device has been configured to enable or turn on the 5G functionalities. Accordingly, the user device may be able to access to the 5G network.
[0027] Nevertheless, as illustrated in the second row of the table in FIG. 2, under some situations, even if both the network and user device are appropriately configured (i.e., ENDC is enabled at the network and 5G connection is enabled at the user device), the user device may still unable to access the 5G network. This may be caused by the aggressive network configurations, which set a high access threshold to the user device. Specifically, since the 5G network is operating at a higher frequency band, it is more prone to radio link failure, high signal path loss, and session discontinuities, as compared to the LTE network. Thus, in order to avoid inconsistent network performance, the network operator may set a high, static access threshold to the user devices (particularly the mobile devices that have high mobility) to prevent excessive and frequent network switching.
[0028] The aggressive network configurations, although may reduce the inconsistent network performance, may result in several negative impacts. On the consumer side, the users that have an active 5G network subscription may find it difficult to fully utilize the 5G network due to the high, static access threshold, which may lead to poor user experiences and eventually increase the user churn rate. On the operator side, the aggressive network configurations may lead to underutilization of the available 5G network, which may cause the wastage of network resources and costs for rolling out and operating the 5G network.
[0029] Referring still to FIG. 2, in the third and fourth rows of the table, the inactivation of the 5G network is due to the network configurations, wherein in the former case the ENDC is disabled (e.g., for network maintenance, energy-saving purposes, etc.) and in the latter case only the LTE network is available (e.g., the 5G roll-out is in process, 5G infrastructure malfunctioning, etc.) The inactivation of the 5G network due to these reasons can be resolved by the network operator via appropriate solutions (e.g., restarting the 5G infrastructure, completing the 5G rollout, etc.)
[0030] Further, in the fifth row of the table in FIG. 2, the inactivation of the 5G network is due to the configuration at the user device, where the user has disabled the 5G connection. For example, the user may have manually turned off the 5G connection on the device when he/she found out that the 5G network is not yet available in his/her area. As another example, the user may have unintentionally turned off the 5G connection without being aware of the same. In this regard, the user would not be able to utilize the 5G network whenever the 5G network is available. [0031] In the last row of the table in FIG. 2, the inactivation of the 5G network is caused by both the configurations at the network and the user device, in which both the scenarios described above with reference to the third row and the fifth row of the table are applicable.
[0032] In view of the above, there are various factors that hinder the usage of the 5G network and there is a need to enhance the usage of the 5G network, thereby optimizing the utilization of the 5G network when available and improving the user experiences, as well as optimizing the network resources and preventing wastage of 5G network roll-out cost and operational cost.
[0033] Example embodiments of the present disclosure provide a system, a method, a device, and the like, that efficiently and effectively enhance the 5G network usage. Specifically, example embodiments of the present disclosure dynamically configure and refine the SPID profile and/or at least one access parameter for accessing the 5G network, according to the status of the user device and the network, thereby maximizing the opportunities for the user device to access and utilize the 5G network under different scenarios. In addition, example embodiments of the present disclosure provide continuous (or periodic) monitoring of the performance of the user device and adjust the SPID profile and/or the access parameter(s) based thereon. Further, example embodiments of the present disclosure detect the available configuration and capability of the user device, and provide a suggestion to the user to configure the user device to connect to the 5G network when applicable. Ultimately, example embodiments of the present disclosure effectively and efficiently optimize the opportunities for the user device to access and utilize the 5G network, thereby enhancing the 5G network usage.
[0034] It is contemplated that features, advantages, and significances of example embodiments described hereinabove are merely a portion of the present disclosure, and are not intended to be exhaustive or to limit the scope of the present disclosure. Further descriptions of the features, components, configuration, operations, and implementations of the example embodiments of the present disclosure are provided in the following.
Example System Architecture
[0035] FIG. 3 illustrates an example system architecture of a distributed non- standalone (NSA) network, according to one or more example embodiments. As illustrated in FIG. 3, the system architecture may include a core network 310, a first user device 320, and a second user device 330.
[0036] It is contemplated that the system architecture in FIG. 3 is simplified for descriptive purposes, and the actual system architecture may be different from FIG. 3 in actual implementations. For instance, in some example implementations, the system may include more components, such as one or more radio components (e.g., LTE eNodeB, 5G gNodeB, etc.) that communicatively couple the user devices to the core network, multiple MME/HSS/PGW/PCRF/OCS, and the like, without departing from the scope of the present disclosure.
[0037] As illustrated in FIG. 3, the core network 310 may be communicatively coupled to the first user device 320 and the second user device 330 via, for example, one or more radio components like an LTE eNodeB and/or a 5G gNodeB. The first user device 320 and the second user device 330 may include at least one of: a mobile device (e.g., a smartphone, a laptop, a table, a wearable device like smartwatches and smartglasses, a portable hotspot, etc.), a static device (e.g., a fixed wireless access (FWA) router, an internet modem, an Internet of Things (loT) device like a security camera, sensors, and smart home devices, etc.), and a mobile device that has been in a static state for a predetermined period of time (e g., a mobile device that has been left on a desk or a charging station for a predetermined period of time, etc.) Merely for descriptive purposes, it may be assumed in the following that the first used device 320 is a mobile device and the second user device 330 is a static device.
[0038] Generally, in the NSA architecture, the user devices may first attach to the LTE network and then establish connectivity with the 5G network when applicable. In this regard, the core network 310 may refer to an LTE core network and may include a mobility management entity (MME) 312, a home subscriber server (HSS) 314, a packet data network gateway (PGW) 316, and a policy and charging rules function (PCRF)/online charging system (OCS) 318.
[0039] According to example embodiments, one or more of the MME 312, HSS 314, PGW 316, and PCRF/OCS 318 (as well as the operations associated therewith) may be implemented in one or more devices (e.g., one or more servers, etc.) For instance, one or more of the MME 312, HSS 314, PGW 316, and PCRF/OCS 318 (as well as the operations associated therewith) may be implemented as a software application(s) or virtualized/containerized network function(s) operating on the one or more devices, in a virtualized environment and the like.
[0040] The MME 312 may be responsible for providing mobility and session management for the users (i.e., the network subscribers). For example, the MME 312 may handle operations such as authentication, handovers between cells (e.g., between LTE cells and/or 5G cells), location updates, establishment and release of bearers, and the like.
[0041] The HSS 314 may be a central server or database that stores and manages user- related and subscription-related information. For example, the HSS 314 may manage and provide information associated with the users/subscribers in the form of a subscriber profile identifier
(SPID). The HSS 314 may provide the information and credentials of the users/subscribers to the MME 312 for user authentication and mobility management. In some example embodiments, the HSS 314 may determine the services the users/sub scribers are allowed to access.
[0042] According to example embodiments, the HSS 314 may be configured to map the SPID of the users/subscribers to the associated International Mobile Subscriber Identity (IMSI) as part of the subscription information. According to example embodiments, when the user devices attach to the network (e.g., initially as IMSI, subsequently as Global Unique Temporary Identifier (GUTI) attach, etc.), the MME 312 carries the subscription keys and derives the SPID as part of the authentication procedure over the S6a interface. The rule sets for this subscription profile is mapped in the RAN nodes (e.g., eNB, gNB, etc.), the PCRF 318, and implemented to the user devices as part of Authorization and Authentication Request (AAR), Re-Authentication Request (RAR), Re- Authentication Answer (RAA) and/or as part of RAN procedures like radio resource control (RRC) reconfiguration where mobility profiles, ENDC profiles (mapped to configurations) are mapped towards the associated user devices on the Air Interface. According to example embodiments, in addition to the SPID profiles, the HSS 314 may be configured to manage one or more profiles defined in one or more 3GPP technical specifications. For example, the HSS 314 may manage a restrictendc profile, which is a 3GPP profile mapped to the subscription of the user and defines the usage restriction of the user towards ENDC.
[0043] The PGW 316 may be responsible for managing the connection of the network to external packet data networks. For example, the PGW 316 may assign Internet Protocol (IP) addresses to the user devices, apply quality of service (QoS) rules to user traffic, and collect data for billing or charging purposes.
[0044] The PCRF/OCS 318 may be responsible for providing policy control and charging functionalities. For example, the PCRF/OCS 318 may determine which service and how the service should be provided to the user devices, apply charging mechanisms for the services used, provide credit control, and the like.
[0045] According to example embodiments, the MME 312 may be configured to coordinate with the HHS 314 to authenticate the user devices and with the PGW 316 for session continuity, before, during, and after the transition of the user devices from the LTE network to the 5G network.
[0046] The MME 312, HSS 314, PGW 316, and PCRF/OCS 318 may interoperate with one another to provide the user devices a seamless transition between the LTE network and the 5G network, when applicable. As described above, in the NSA architecture, the user devices may initially connect to the LTE network, and then switch to the 5G network when applicable. In this case, when the user devices first attach to the LTE network, the MME 312 may be configured to authenticate the user devices by interacting with the HSS 314. If the network supports dual connectivity (e.g., ENDC, etc.), the MME 312 may determine whether or not the current configuration of the user devices is capable of connecting to the 5G network (e.g., whether or not the user devices are 5G capable, whether or not the associated users have active 5G subscriptions, etc.) The MME 312 and the HSS 314 may communicate to each other via an S6a interface (i.e., a diameter interface).
[0047] For example, the MME 312 may communicate with the HSS 314 to authenticate the user devices and retrieve the subscription profile (e.g., SPID profile, etc.), which may include parameters like Dual Connectivity with New Radio (DCNR) parameter, device Type Allocation Code (TAC), and the like, that specify the current configuration and capability of the user devices
(e.g., 5G capable, LTE capable only, 5G capable but 5G connection is disabled, etc.) In addition, the subscription profile may also include information about the services the user devices subscribed to. Accordingly, the MME 312 may utilize the information provided by the HSS 314 to determine whether or not the current configuration of the user devices is capable of connecting to the 5G network.
[0048] In some example embodiments, based on determining that the current configuration of the user devices is not capable of connecting to the 5G network, the MME 312 may further determine whether or not the user devices can be configured to connect to the 5G network. For instance, the MME 312 may utilize the device TAC, and/or may utilize the DCNR bit to determine whether or not the user device is a 5G capable device. For example, based on determining that the device TAC indicates that the user device is 5G capable (e.g., Device TAC = 5G Capable, etc.), and/or based on determining that the DCNR bit indicates that the user device is 5G capable (e g., DCNR Bit mapping= 1, etc.), the MME 312 may determine that the user device is 5G capable but the 5G connection is turned off by the user. In this regard, the MME 321 may provide a notification (e g., by triggering an Application-to-Person (APS) message, etc.) to suggest the user to turn on the 5G connection, such that the user device can connect to the 5G network thereafter. According to example embodiments, before providing the notification to the user, the MME 312 may further take other conditions or predefined metrics (e.g., the network coverage, network quality, network capacity, etc.) into consideration, to determine whether or not the suggestion should be provided to the user. Accordingly, the MME 312 may again determine whether or not the current configuration of the user device (if reconfigured) is capable of connecting to the 5G network, as described above.
[0049] On the other hand, based on determining that the current configuration of the user device is capable of connecting to the 5G (e.g., the user device is appropriately configured and the 5G connection is enabled, etc.), the MME 312 may determine the mobility state of the user device, wherein the mobility state may define the user device as one of: a mobile device, a static device, and a mobile device that has been in a static state for a predetermined period of time.
[0050] For instance, the MME 321 may monitor the location, mobility, and connectivity status of the user device, as well as the associated historical data, to determine whether the user device has been staying within an area for a predetermined period of time. In this case, if the user device has moved from one area to another area within a first period of time (or has a history of frequently moving from one area to another area in the past), the MME 321 may determine that the user device is a mobile device. On the other hand, if the user device has been staying within the area for more than the first period of time but is moving to another area (or has a history of moving to another area in the past) within a second period of time, the MME 321 may determine that the user device is a mobile device that has been in the static state for a predetermined period of time. Further, if the user device has been staying within the area for more than the second period of time (or has not been moving out from the area in the past), the MME 321 may determine that the user device is a static device. In some example embodiments, the mobility state of the user device may be represented in an associated term, i.e., the mobility state of a mobile device is "dynamic", the mobility state of a static device is "static", the mobility state of a mobile device that has been in a static state for a predetermined period of time is “idle”, and the like.
[0051] It is contemplated that the mobility state of the user device may also be determined and provided to the MME 312 in any suitable method, without departing from the scope of the present disclosure. For example, the mobility state of the user device may be determined by the system and method described in US Patent No. 10, 499, 294.
[0052] Upon determining the mobility state of the user device, the MME 312 may provide the information to the HSS 314, and the HSS 314 may be configured to manage the associated setings for accessing the 5G network. For instance, the HSS 314 may configure an SPID profile (e.g., create a new SPID profile, update an existing SPID profile, etc.) for each of the associated user devices based on the mobility state of the user device, and then adjust or set at least one access parameter associated with the user device(s) based on the configured SPID profile. Further, according to example embodiments, the HSS 314 may be configured to manage the SPID profile based on the associated IMSI range.
[0053] According to example embodiments, the at least one access parameter may include at least one of an access threshold for accessing the 5G network, a secondary cell group (SCG) type, a split type, a priority, and an operational frequency band. In some example implementations, the HSS 314 may create/manage an SPID profile for each of the user devices. Alternatively, the HSS 314 may create/manage an SPID profile for a plurality of user devices.
[0054] FIG. 4 illustrates an example of an SPID profile, according to one or more example embodiments. In this example, the SPID profile is presented in the table-form and contains the configuration of a plurality of access parameters associated with a plurality of user devices. As illustrated in FIG. 4, the access parameters may include: a Secondary Cell Group (SCG) type which specifies the frequency range (e.g., FR1 which includes sub-6 GHz frequency bands, FR2 which includes millimeter wave bands, etc.) of the associated SCG, Bl threshold (i.e., a type of access threshold defined in one or more 3GPP technical specifications), a split type which specifies the bearer types (e.g., SCG bearer, master cell group (MCG) bearer, split bearer, etc.), a priority, an E-UTRA Absolute Radio Frequency Channel Number (EARFCN) which specifies the operational frequency band (e.g., N77 and N78 are in the FR1 range, N256 is in the FR2 range), and the like. [0055] Referring back to FIG. 3, as described above, the HSS 314 may be configured to set at least one access parameter (e.g., at least one of the parameters illustrated in FIG. 4). By way of example, assuming that the first user device 320 is a mobile device and the second user device 330 is a static device, the HSS 314 may assign a higher access threshold (e.g., -105 dbm) to the first user device 320 and a lower access threshold (e.g., -111 dbm) to the second user device 330. This is because, the network coverage and performance for the second user device 330 is easier to predict due to the low mobility (or no mobility), and the second user device 330 is expected to be less prone to variation of network environment (e.g., distance between the second user device 330 to the radio component, etc.) as compared to the first user device 320. Conversely, since the first user device 320 is a mobile device and the associated mobility, network coverage, and the like are more unpredictable, the first used device 320 is expected to be more prone to variation of network environment as compared to the second user device 330. Thus, the HSS 314 may assign the first user device 320 with a higher access threshold (e.g., -105 dbm) and assign the second user device 330 with a lower access threshold (e.g., -I l l dbm).
[0056] It is contemplated that, in case there is a third user device that is determined as a mobile device that has been staying in the static state for a predetermined period of time, the HSS 314 may assign the third user device an access threshold higher than the second user device 330 and lower than the first user device 320 (e.g., -108 dbm), due to the similar reasons. Further, it is contemplated that the HSS 314 may appropriately configure other access parameters (e g., SCG type, split type, priority, operational frequency band, etc.) for the user devices in a similar manner. Furthermore, it is contemplated that the HSS 314 may appropriately configure the access parameters based on other factors or parameters, such as a type of ongoing activity in the user device (e.g., web browsing, video streaming, etc.), without departing from the scope of the present disclosure. [0057] Upon configuring the access param eter(s), the HSS 314 may include the configured access parameter(s) into the SPID profile and then provide the SPID profile to the MME 312. Accordingly, the MME 312 may provide the SPID profile to the radio components such that the radio components may enforce or activate the SPID profile to determine whether or not a handover process to the 5G network should be triggered for the user device.
[0058] According to example embodiments, after providing the SPID profile to the radio components, the MME 312 and HSS 314 may be configured to continuously (or periodically) measure or determine the performance of the user device under the configured access parameter (e.g., configured access threshold, etc.), and then reconfigure the SPID profile and/or the access param eter(s) to further improve the performance, if required. For example, based on determining that the performance of a user device is suboptimal (e.g., the signal quality degrades or has not improved, etc.), the HSS 314 may adjust the SPID profile and/or the access parameter(s) to optimize the performance of the user device. In this regard, the MME 312 and HSS 314 may receive information associated with the performance of the user device under the configured SPID profile and/or access parameter(s), and then reconfigure the SPID profile/access parameter(s) thereafter. Accordingly, a closed-loop performance determination and reconfiguration of the SPID profile and/or access parameter(s) can be achieved for at least a predetermined period of time.
[0059] It is contemplated that one or more additional operations may be performed throughout the processes described above. For instance, according to example embodiments, before determining the mobility state of the user device, the MME 312 may take into consideration other conditions or factors to determine whether or not the determination of the mobility state of the user device is required. [0060] In some example embodiments, prior to the determining the mobility state of the user device, the MME 312 may determine whether or not the current network to which the user device is attached is required to be improved. For instance, the MME 312 may determine whether or not a traffic share of the user device is lower than at least one predefined metric, such as at least one of: a parameter associated with a network coverage, a parameter associated with a network quality, a parameter associated with an average revue per unit (ARPU), a parameter associated with a churn rate, a parameter associated with a network traffic distribution, and the like, indicating that the network performances is required to be improved. For example, when the user device has a low traffic share but contributes to a high ARPU, it may indicate that the associated user subscribes to a high-cost plan but does not (or cannot) utilize a lot of data. As another example, when the user device has a low traffic share lower than a predefined chum rate, it may indicate that the associated user may be planning to switch to a different network operator/provider, thus reducing the usage on the current network. In these cases, the network performance is required to be improved so as to improve the user experience.
[0061] Accordingly, based on determining that the traffic share of the user device is lower than the at least one predefined metric, the MME 312 may determine (e.g., based on the DCNR of the user device, etc.) whether or not the current configuration of the user device is capable of connecting to the 5G network (i.e., whether or not the user device can be switched to the 5G network to improve the user’s experiences), and then determine the mobility state of the user device based on determining that the current configuration of the user device is capable of connecting to the 5G network, in a similar manner described above. On the other hand, based on determining that the current configuration of the user device is not capable of connecting to the 5G network, the MME 312 may determine (e.g., based on the TAC ofthe user device, etc.) whether or not the user device can be configured to connect to the 5G network, and then provide a suggestion to the user to configure the user device to connect to the 5G network based on determining that the user device can be configured to connect to the 5G network, in a similar manner described above.
[0062] In view of the above, example embodiments of the present disclosure dynamically assess the conditions of the network and the user devices and then appropriately configure the SPID profile and/or the access parameter(s), thereby optimizing the opportunities for the user devices to access and adopt the 5G network according to the latest conditions of the network and the user devices. Further, based on determining that the user devices can be configured to access the 5G network but the current configuration of the user devices is not capable of accessing the 5G network (e.g., the 5G connection is turned off or disabled by the user, etc.), example embodiments of the present disclosure may provide a notification to suggest the user to configure the associated user device(s), such that the opportunities for leveraging the 5G network would not be wasted. Furthermore, example embodiments continuously (or periodically) refine the configuration of the SPID profile/access parameter(s) based on the performance of the user devices, thereby optimizing the performance of the user devices. Ultimately, example embodiments of the present disclosure may effectively and efficiently enhance the usage of the 5G network, thereby improving the user experiences, reducing subscriber’s churn rate, and reducing wastage of network resources and operational costs.
Example Operations
[0063] In the following, descriptions of the example operations according to one or more example embodiments are described. In this regard, it can be understood that one or more operations described herein may be performed by a device (or a system comprising the device). For example, the system/device may include a processor and a storage medium storing computer- readable instructions for implementing the components of the core network 310 (e.g., MME 312, HSS 314, etc.) or the associated operations. In this case, the processor may be configured to execute the computer-readable instructions to perform one or more operations described herein. Descriptions of an example device that may be configured to implement the example embodiments are described below with reference to FIG. 6.
[0064] FIG. 5 illustrates a block diagram of a method 500 for enhancing the usage of the 5G network, according to one or more embodiments. As illustrated in FIG. 5, at operation S510, the system/device may be configured to determine a mobility state of a user device. In some example embodiments, the device may be configured to simultaneously (or sequentially) determine the mobility states of a plurality of user devices. The mobility state may be presented in terms of “dynamic”, “static”, and “idle”, and may define the user device as one of: a mobile device, a static device, and a mobile device that has been in a static state for a predetermined period of time.
[0065] Upon determining the mobility state of the user device, the method 500 may proceed to operation S520, at which the system/device may be configured to configure, based on the mobility state of the user device, a subscriber identifier (SPID) profile associated with the user device. For instance, the device may create a new SPID profile and include the information of the determined mobility state therein. Alternatively, the device may update an existing SPID profile associated with the user device to include the information of the determined mobility state therein. [0066] Upon configuring the SPID profile, the method 500 may proceed to operation S53O, at which the system/device may be configured to set or adjust at least one access parameter based on the configured SPID profile. The access parameter may include at least one of an access threshold for accessing a 5G network (e.g., Bl threshold), an SCG type, a split type, a priority, an operational frequency band (e.g., EARFCN), and the like. The system/device may set or assign the access parameter (or adjust an assigned access parameter) according to the mobility state of the user device defined in the SPID profile.
[0067] Further descriptions of the example operations for determining the mobility state of the user device, configuring the SPID profile, and configuring the access parameter(s), have been described above with reference to FIG. 3, thus redundant descriptions associated therewith may be omitted below for conciseness.
[0068] Upon configuring the access parameter, the method 500 may be terminated. Alternatively, the method 500 may proceed to operation S540 and then return to operation S520/S530, at which the system/device may be configured to provide a closed-loop performance determination and reconfiguration of the SPID profile and/or the access parameter(s). Specifically, at operation S540, the system/device may be configured to receive information associated with the performance of the user device under the configured SPID profile and/or the configured access parameter. Accordingly, the method 500 may return to operation S520 such that the system/device may adjust or reconfigure the SPID profile based on the received information. Alternatively or additionally, the method 500 may return to operation S530 such that the system/device may adjust or reconfigure the access parameter(s) based on the received information.
[0069] According to example embodiments, prior to the determining of the mobility state of the user device (at operation S510), the system/device may be configured to determine whether or not an improvement of the network performance is required. For instance, the system/device may determine whether or not a traffic share of the user device is lower than at least one predefined metric, and then determine whether or not a current configuration of the user device is capable of connecting to the 5G network, based on determining that the traffic share of the user device is lower than the at least one predefined metric. Accordingly, based on determining that the current configuration of the user device is capable of connecting to the 5G network, the system/device may then determine the mobility state of the user device.
[0070] According to example embodiments, the at least one predefined metric may include at least one of: a metric associated with a network coverage (e.g., a threshold associated with signal strength, geographical coverage, etc.), a metric associated with a network quality (e.g., a threshold associated with latency, jitter, packet loss, throughput, etc ), a metric associated with an average revenue per unit (e.g., a threshold associated with the ARPU, etc.), a metric associated with a chum rate (e.g., a threshold associated with a number of lost subscribers, etc.), and a metric associated with a network traffic distribution (e.g., a threshold associated with traffic volume, peak traffic duration, etc.)
[0071] According to example embodiments, the system/device may be configured to determine whether or not the current configuration of the user device is capable of connecting to the 5G network based at least on a DCNR indicator associated with the user device.
[0072] According to example embodiments, based on determining that the current configuration of the user device is not capable of connecting to the 5G network, the system/device may be configured to determine whether or not the user device can be configured to connect to the 5G network.
