Description

[0001] This application is a divisional application of an invention patent application with an application date of April 27, 2020, application number 202080030891.9, and invention name “Method and system for managing new radio (NR) communications in electronic devices”. Technical Field

[0002] The present disclosure relates generally to wireless communication systems, and more particularly, to methods and systems for managing New Radio (NR) communications in electronic devices in wireless communication systems. Background Art

[0003] The introduction of NR technology (also known as fifth generation (5G) technology or 5G NR technology) may result in changes in mobile network architecture. These changes may result in mobile network architectures supporting multiple radio access technologies (RATs), such as NR, Evolved Packet Core (EPC), Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN), Global System for Mobile Communications - Evolved RAN (G-ERAN), and Universal Mobile Telecommunications System - Terrestrial RAN (U-TRAN). Managing electronic device (or user equipment (UE)) connections within these mobile network architectures supporting multiple RATs may introduce situations that do not need to be addressed in traditional mobile network architectures.

[0004] If the electronic device supports the E-UTRAN NR Dual Connectivity (EN-DC) feature, the Long Term Evolution (LTE) RAT bearer network will become the primary cell group (MCG) bearer, and the NR RAT bearer network will become the secondary cell group (SCG) bearer. The MCG can be used as an anchor cell group band, and the electronic device performs initial registration with the anchor cell group. The anchor cell group can add one or more secondary cells of the SCG. When EN-DC is configured, user data carried by a dedicated radio bearer (DRB) can be delivered via the MCG, via the NR SCG, or via both the MCG and the NR SCG. In addition, the radio resource control (RRC) signaling carried by the signaling radio bearer (SRB) can be delivered via the MCG or via both the MCG and the NR SCG.

[0005] In addition, the base station (or evolved Node B (eNB)) can configure the RRC-connected electronic device to perform measurements, and the electronic device can report the measurement report according to the measurement configuration. The base station can configure different types of measurements, such as NR measurements of E-UTRAN frequencies and inter-RAT measurements. Based on receiving the NR measurement report from the electronic device, the base station can add an NRSCG for dual connectivity. SCG is a radio bearer for additional resources (such as 5G services) served only by the next generation base station (gNB). However, performing frequent NR measurements and adding NR SCGs will unnecessarily consume power in the electronic device.

[0006] As an example, Figure 1 A schematic diagram shows a conventional method of performing NR measurements while there is no or minimal data activity in an electronic device or when mobile data is turned off or when a Wireless Fidelity (Wi-Fi) connection occurs.

[0007] In step 1, the electronic device sends an attach request including dual connectivity supporting NR to the eNB, and the eNB may accept the attach request. Figure 1 As shown, an Internet Protocol (IP) Multimedia Subsystem (IMS) Packet Data Network (PDN) may be established between an eNB and an electronic device.

[0008] In step 2, the electronic device may initiate a Voice over LTE (VoLTE) call using the IMS PDN based on a user request. At the same time, the eNB may send configuration information corresponding to event B1-NR to the electronic device for performing NR measurements during the VoLTE call and no / minimal data activity. Event B1 is used for inter-RAT measurements.

[0009] In step 3, the electronic device sends a B1-NR measurement report to the eNB, and in response, the eNB may add an SCG based on event B1-NR even if no data activity / minimal data activity is observed in the electronic device. Event B1-NR is used for NR RAT measurements. Adding SCGs that may not be needed during no data activity / minimal data activity often results in excessive power consumption in the electronic device.

[0010] Similarly, if Figure 1 If the mobile data is turned off in the electronic device in the mobile data off state, then when there is mobile data activity / no minimum data activity, steps 1 and 2 are similar to the above. In step 3, the electronic device sends a B1-NR measurement report to the eNB, and in response, the eNB can add an SCG based on event B1-NR even if the mobile data is turned off in the electronic device. Adding a SCG that may not be needed during the mobile data off state of the electronic device often leads to excessive power consumption in the electronic device.

[0011] if Figure 1 In the embodiment of the present invention, if the electronic device in the state of connecting to a Wi-Fi network is connected to a Wi-Fi network, then in the case of mobile data activity / no minimum data activity, steps 1 and 2 are similar to those described above. The electronic device is connected to a Wi-Fi network, during which the IMS PDN may not be required. In step 3, the electronic device may send a B1-NR measurement report to the eNB, and in response, the eNB may add an SCG based on event B1-NR even if the electronic device is connected to a Wi-Fi network. Adding a SCG that may not be required during the connected to Wi-Fi network state of the electronic device often results in excessive power consumption in the electronic device.

[0012] If a state of mobile data off, no data activity / minimal data activity is observed after adding the SCG, and a Wi-Fi network connection of the electronic device is detected, the conventional method may not release the added SCG even if there is no need to retain the SCG. Since there is no data activity / minimal data activity / Wi-Fi network / mobile data is off, unnecessary power consumption often occurs in the electronic device to retain the SCG.

[0013] Figure 2A A conventional method is shown with no / minimal data activity or mobile data turned off or connection to Wi-Fi turned on in an electronic device.

[0014] In step 202a, the electronic device sends an attach request including dual connectivity supporting NR to the MME. The attach request is sent with a default access point name (APN), such as the Internet, only when the mobile data is turned off or the electronic device is connected to Wi-Fi. In step 202b, the MME accepts the attach request without restricting the use of the dual connectivity. In step 202c, an Internet PDN may be established between the MME and the electronic device. In step 202d, an IP Multimedia Subsystem (IMS)-PDN may be established between the MME and the electronic device even if no data activity / minimal data activity is observed in the electronic device. The IMS PDN may not be established when the mobile data is turned off or the electronic device is connected to Wi-Fi. In step 202e, configuration information for event B1-NR measurement is received from the base station. In step 202f, a state of no data activity / minimal data activity or turning off mobile data or connecting to Wi-Fi is observed in the electronic device. In step 202g, the electronic device performs B1-NR measurement of the next generation base station, even if the SCG does not need to be added when the electronic device is in a state of no data activity / minimal data activity or turning off mobile data or connecting to Wi-Fi. In step 202h, the base station adds NR as an SCG based on the B1-NR measurement report, which often results in unnecessary power consumption in the electronic device.

[0015] Figure 2B A conventional method is shown in which the base station does not add an SCG even after the electronic device sends multiple B1-NR measurement reports. In step 208a, the RRC is in a connected state with a base station (such as an LTE network). In step 208b, the base station sends an RRC reconfiguration with an NR measurement object to the electronic device. In steps 208c-208g, the electronic device sends a B1-NR measurement report with an NR cell to the base station multiple times. Even if there are consecutive measurement reports containing NR cells, the base station does not add an SCG.

[0016] Figure 2C A conventional method is shown in which there is frequent NR-radio link failure (NR-RLF) due to a transmission power limitation problem in an electronic device. In step 210a, the RRC is in a connected state with an LTE network. In step 210b, the base station sends an RRC reconfiguration with an NR measurement object to the electronic device. In step 210c, the electronic device sends a B1-NR measurement report with an NR cell to the base station. In step 210d, the base station sends an RRC reconfiguration with an SCG addition to the electronic device. Accordingly, in step 210e, data transfer between the electronic device and the next generation base station is performed.

[0017] In step 210f, the electronic device moves to the LTE cell edge area, and the electronic device increases the LTE transmission power. In step 210g, high transmission power in LTE may be provided for VoLTE continuity. In step 210h, RLF may occur in NR due to low transmission power. As a result, in step 210i, LTE is in RRC connection mode. In step 210j, the base station sends an RRC reconfiguration with an NR measurement object to the electronic device. In step 210k, the electronic device sends a B1-NR measurement report with an NR cell to the base station. In step 210l, the base station sends an RRC reconfiguration with SCG addition to the electronic device. Accordingly, in step 210m, data transfer between the electronic device and the next generation base station is performed. In step 210n, the electronic device moves to the LTE cell edge area, and the electronic device increases the LTE transmission power. In step 210o, high transmission power in LTE may be provided for VoLTE continuity. In step 210p, RLF may occur in NR due to low transmission power in NR. Therefore, as SCG addition occurs, there are frequent NRs, and there are frequent NR RLFs in short durations, which tend to cause excessive power consumption in electronic devices.

[0018] Figure 2D A conventional method is shown in which there is frequent NR radio link failure (NR-RLF) due to an NR cell edge area of ​​an electronic device. In step 212a, the RRC is in a connected state with an LTE network. In step 212b, the base station sends an RRC reconfiguration with an NR measurement object to the electronic device. In step 212c, the electronic device sends a B1-NR measurement report with an NR cell to the base station. In step 212d, the base station sends an RRC reconfiguration with an SCG addition to the electronic device. Accordingly, in step 212e, data transfer between the electronic device and the next generation base station is performed.

[0019] In step 212f, the electronic device moves to the NR cell edge area. In step 212g, NR RLF may occur due to poor NR RLF signal. As a result, in step 212h, the base station sends an RRC reconfiguration with an NR measurement object to the electronic device. In step 212i, the electronic device sends a B1-NR measurement report with an NR cell to the base station. In step 212j, the base station sends an RRC reconfiguration with SCG addition to the electronic device. Accordingly, in step 212k, data transfer between the electronic device and the next generation base station is performed. In step 212l, the electronic device moves to the NR cell edge area. In step 212m, NR RLF may occur due to poor NR RLF signal. Therefore, as SCG addition occurs, there is frequent NR, and there is frequent NR RLF in a short duration, which tends to cause excessive power consumption in the electronic device.

[0020] Figure 2E A conventional method in which frequent NR synchronization failure or NR random access channel (RACH) failure exists is shown. In step 214a, the RRC is in a connected state with the LTE network. In step 214b, the base station sends an RRC reconfiguration with an NR measurement object to the electronic device. In step 214c, the electronic device sends a B1-NR measurement report with an NR cell to the base station. In step 214d, the base station sends an RRC reconfiguration with SCG addition to the electronic device. In step 214e, an NR cell search failure or an NR RACH failure may occur. As a result, in step 214f, the electronic device sends a B1-NR measurement report with an NR cell to the base station. In step 214g, the base station sends an RRC reconfiguration with SCG addition to the electronic device. In step 214h, an NR cell search failure or an NR RACH failure may occur again. As a result, in step 214i, the electronic device resends the B1-NR measurement report with the NR cell to the base station. In step 214j, the base station sends an RRC reconfiguration with SCG addition to the electronic device. In step 214k, NR cell search failure or NR RACH failure may occur. Summary of the invention

[0059] Although the embodiments of this document are described using NR communications, they are merely examples. Therefore, the embodiments of this document are applicable to any other communication system, such as an advanced LTE (LTE-A) network, a 5G network, a 5G core (5GC) network, etc. The communication system may include a RAN and a core network (CN).

For example, the CN may be an EPC network or a 5GC network.

[0060] Disclosed herein are methods and systems for managing NR communications in electronic devices. A network management system associated with an electronic device may receive configuration information for event B1-NR measurements from a base station. When an NR cell for dual connectivity between multiple RATs is to be added, the base station configures event B1-NR for measurement or sends configuration information to the electronic device. When the event B1-NR criterion is met, it means that the measurement value of the NR neighboring cell is greater than the configured threshold. When the B1-NR criterion is met, the electronic device may trigger a B1-NR measurement report for event B1-NR measurement. Based on the B1-NR measurement report, the base station adds an NR cell for dual connectivity via a next-generation base station. The configuration information may indicate a trigger threshold for triggering the electronic device to send a B1-NR measurement report. Event B1-NR may be randomly configured by the base station, or may be configured based on LTE / NR signal strength.

[0061] The B1-NR measurement report is sent to the base station to add the SCG associated with the NR by the base station. Based on the received configuration information, the network management system can monitor at least one state of the electronic device. At least one state of the electronic device may include, but is not limited to, no mobile data activity, minimal mobile data activity, mobile data disabled, connected to a Wi-Fi network, and frequent NR connection failures during the addition of the SCG. The SCG can be an NR RAT. The network management system can periodically monitor at least one state of the electronic device to obtain any changes in at least one state. Based on the monitoring of at least one state, when at least one state of the monitored electronic device is met, the network management system can limit at least one of the NR capabilities and NR measurements of the electronic device.

[0062] The description of an embodiment with several components in communication with each other does not imply that all such components are required. Rather, various optional components are described to illustrate possible embodiments.

[0063] In the following detailed description, reference is made to the accompanying drawings, which show, by way of illustration, embodiments in which the present disclosure may be implemented. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present disclosure, and it will be understood that other embodiments may be utilized and changes may be made without departing from the scope of the present disclosure.

[0064] Figure 3 An architecture 300 for managing NR communications in an electronic device is shown according to an embodiment.

[0065] The architecture 300 includes an electronic device 302, a network management system 304 associated with the electronic device 302, a base station 306 (eNB), a gNB 308, and an EPC 310. The network management system 304 may be configured in the electronic device 302. The electronic device 302 may include, but is not limited to, a mobile phone, a cellular phone, a smart phone, a tablet, a phablet, a smart watch, a laptop, a notebook, an e-reader, etc. The network management system 304 may be associated with the electronic device 302 via a communication network. The communication network may be at least one of a wired communication network and a wireless communication network. The EPC 310 also includes a mobility management entity (MME) 312, a PDN gateway (PGW) 314, and an SGW 316. The base station 306 may communicate with the MME 312 and / or the SGW 316 via a signaling interface. The base station 306 may communicate with the next generation base station 308 via a network interface. The EPC 310 determines whether the electronic device 302 is authorized for DC access during the attachment process. The EPC 310 may be responsible for providing aggregated voice and data on the 4G LTE network. The EPC 310 may also support the handover of bearers between the base station 306 and the next generation base station 308. The MME 312 may be responsible for managing session states and authenticating and tracking the electronic device 302 across the network coverage of the base station 306. The PGW 314 may serve as an interface between the base station 306 and the next generation base station 308 and may manage quality of service (QoS). The SGW 316 may be responsible for routing data packets to the electronic device 302 via the base station 306.

[0066] The network management system 304 may include a processor 318, an input / output (I / O) interface 320, and a memory 322. The I / O interface 320 may be configured to receive input from a user of the electronic device 302, such as turning off mobile data, turning on mobile data, connecting to / disconnecting from a Wi-Fi network, and performing a VoLTE call. The network management system 304 may determine minimum mobile data activity and no mobile data activity in the electronic device 302 based on information from at least one of a packet data convergence protocol (PDCP) entity in the electronic device 302, a media access control layer-buffer status report (MAC-BSR) of the electronic device 302, and the like.

[0067] A network management system 304 associated with the electronic device 302 is configured to receive configuration information for event B1-NR measurement from the base station 306. The configuration information may indicate a triggering threshold for triggering the electronic device 302 to send a B1-NR measurement report. The configuration information (such as an RRC connection reconfiguration message) may include information about the type of event that the electronic device 302 must report and information about the type of measurement to perform the B1-NR measurement.

[0068] If the electronic device 302 is attached to the base station 306 as an electronic device 302 with EUTRA NR-DC (EN-DC) capability, the base station 306 requests a B1-NR measurement report from the electronic device 302 for adding NR to the electronic device 302 as an SCG. Based on the configuration information for event B1-NR measurement received from the base station 306, the network management system 304 is configured to periodically monitor at least one state of the electronic device 302. The at least one state of the electronic device 302 includes, but is not limited to, at least one of no mobile data activity, minimal mobile data activity, mobile data disabled, connected to a Wi-Fi network, and frequent NR connection failure during the addition of the SCG. Frequent NR connection failures include, but are not limited to, at least one of NR RLF, NR synchronization failure, NR RACH failure, and sending an NR measurement report without NR measurement to the base station 306. Based on the monitoring, when at least one state of the electronic device 302 is satisfied, the network management system 304 limits at least one of the NR capability and NR measurement of the electronic device 302. When at least one state of the electronic device 302 is not satisfied, the network management system 304 enables at least one of the NR capability and NR measurement of the electronic device 302. Once the NR capability and NR measurement of the electronic device 302 are enabled, the network management system 304 is configured to send a B1-NR measurement report to the base station 302 for adding an SCG.

[0069] After the NR connection failure is first determined during the addition of the SCG, the network management system 304 is configured to disable the NR capability of the electronic device for a first predetermined time. After each subsequent NR connection failure, the first predetermined time is iteratively increased. For example, the first predetermined time may be a duration of 'X' minutes, and after the expiration of X minutes, the network management system 304 may enable the NR capability of the electronic device 302. If the NR connection failure occurs again (such as 5 NR connection failures within 1 minute on the same NR cell), the network management system 304 may be more aggressive in disabling the NR capability of the electronic device 302 for a 2X duration because it determines that the NR connection failure still exists in the same NR cell. Similarly, if the NR connection failure continues, the NR capability of the electronic device 302 is disabled for a 3X duration, then a 4X duration, and so on. The network management system 304 is configured to restrict NR measurements, whereby a B1-NR measurement report is not sent to the base station 306, and in response, the base station 306 does not add NR as an SCG.

[0070] The network management system 304 is configured to disable the NR capability of the electronic device 302 for a first predetermined time after first determining to disable at least one of mobile data, no mobile data activity, minimum mobile data activity, and connection to a Wi-Fi network. After each determination to disable at least one of mobile data, no mobile data activity, minimum mobile data activity, and connection to a Wi-Fi network, the first predetermined time is iteratively increased. The network management system 304 is configured to determine whether the base station 306 has added an SCG associated with NR via the next generation base station 308. In order for the base station 306 to release the SCG that has been added, the network management system 304 determines whether configuration information for event A2-NR measurement is received from the next generation base station 308. Event A2 is triggered to perform NR cell measurement, and the configuration information is configured or sent to the electronic device by the next generation base station 308. Event A2-NR measurement is configured to monitor the status of the NR service cell. When the A2-NR event criteria are met, this means that the measurement value of the NR service cell has become less than the configured threshold. Based on the A2-NR measurement report from the electronic device 302, the next generation base station 308 may decide to release the serving cell or configure other NR events, such as A3 (the measurement value of the neighboring cell becomes better than the measurement value of the serving cell) or A5 (the serving cell becomes worse than the threshold 1 and the neighboring cell becomes better than the threshold 2). If the configuration information for the event A2-NR measurement is received from the next generation base station 308, the network management system 304 is configured to send the poor NR cell measurement to the next generation base station 308 in the A2-NR measurement report. If the configuration information for the event A2-NR measurement is not received from the next generation base station 308, and if the next generation base station 308 does not release the SCG, the network management system 304 is configured to notify the next generation base station 308 about the disabled NR capability of the electronic device 302 and the indication of the SCG failure, so that the next generation base station 308 releases the SCG that has been added. In addition, the network management system 304 is configured to restrict NR measurement. Therefore, the B1-NR measurement report is not sent to the base station 306, and in response, the base station 306 does not add NR as an SCG.

[0071] The network management system 304 may also be configured to configure a plurality of NR frequencies for event B1-NR measurement. The network management system 304 is configured to limit NR measurement for at least one of at least one NR frequency among the plurality of frequencies and at least one NR cell with frequent NR connection failures. The network management system 304 is configured to perform NR measurement for at least one of the remaining NR frequencies and the remaining NR cells among the plurality of NR frequencies (except for the limited at least one NR frequency and the limited at least one NR cell).

[0072] The network management system 304 is configured to determine whether the electronic device 302 is located in at least one of the LTE cell edge area and the NR cell edge area. If the electronic device is located in the LTE cell edge area or the NR cell edge area, the network management system 304 is configured to allocate a greater transmission power to the LTE communication of the electronic device 302 than the NR communication of the electronic device 302. The network management system 304 is configured to monitor the NR RLF. When the occurrence of the NR RLF is detected while the NR RLF is monitored for the first time, the NR capability of the electronic device 302 is disabled within a first predetermined time. When at least one of the NR RLF failure count of the monitored NR RLF is greater than the predetermined count and the NR RLF failure time is greater than the second predetermined time, the NR capability of the electronic device 302 is disabled. After each subsequent NR RLF, the first predetermined time is iteratively increased.

[0073] The network management system 304 is configured to continuously reconfigure the RRC connection with the addition of the SCG. If the RRC connection is reconfigured for at least one of an RRC reconfiguration count greater than a predetermined count and an NR synchronization time or a RACH failure time greater than a second predetermined time, the network management system 304 is configured to disable the NR capability of the electronic device 302 for a first predetermined time. The network management system 304 is configured to continuously transmit NR measurement reports to add SCGs. When an NR measurement report is transmitted for a report transmission count greater than a predetermined count or an SCG addition time greater than a second predetermined time, the network management system 304 is configured to disable the NR capability of the electronic device 302 for a first predetermined time.

[0074] Scenario 1

[0075] Figure 4 A schematic diagram is shown when an event B1-NR configuration is received according to an embodiment, when no data activity / minimal data activity is observed in an electronic device or mobile data is turned off or connected to Wi-Fi.

[0076] In step 1, the electronic device 302 sends an attach request including dual connectivity supporting NR to the base station 306, and the base station 306 may accept the attach request. An IMS PDN may be established between the base station 306 and the electronic device 302. Subsequently, a VoLTE call may be initiated. At the same time, even if the VoLTE call does not require the addition of an SCG, the base station 306 may send configuration information for event B1-NR measurement to the electronic device 302.

[0077] In step 2, the network management system 304 configured in the electronic device 302 may determine that there is no data activity / minimum data activity state or mobile data is turned off in the electronic device 302, and in response, the network management system 304 may disable NR capabilities and limit NR measurements. In step 3, the B1-NR measurement report is not sent to the base station 306, and in response, the base station 306 does not add the SCG.

[0078] When Figure 4 When the electronic device 302 is connected to a Wi-Fi network, steps 1 and 3 are the same as described when there is no data activity / minimal data activity or mobile data is turned off in the electronic device 302. In step 2, the network management system 304 configured in the electronic device 302 may determine that the electronic device 302 is connected to a Wi-Fi network, and in response, the network management system 304 may disable NR capabilities and limit NR measurements. If the electronic device 302 is connected to a Wi-Fi network, it may not be necessary to add an SCG.

[0079] Figure 5A A timing diagram of a method of having no data activity / minimal data activity or turning off mobile data or connecting to Wi-Fi in an electronic device when an event B1-NR configuration is received according to an embodiment is shown.

[0080] The attach request, attach accept, PDN establishment, and IMS PDN establishment steps may be performed between the electronic device 302 and the MME 312 according to a predetermined procedure. Subsequently, the base station 306 may send configuration information to the electronic device 302 to perform NR measurement and send a B1-NR measurement report. In step 502a, the network management system 304 configured in the electronic device 302 may monitor and determine that there is no data activity / minimum data activity or the mobile data is turned off or connected to Wi-Fi in the electronic device 302. In step 502b, the network management system 304 configured in the electronic device 302 may not perform NR measurement of the next generation base station 308. In step 502c, the network management system 304 configured in the electronic device 302 may detect that the data activity is resumed or the mobile data is turned on or disconnected from the Wi-Fi, and use the mobile data to perform data activity in the electronic device 302. In step 502d, the network management system 304 configured in the electronic device 302 may enable NR measurement and start NR measurement of the next generation base station 308.

[0081] Figure 5B A timing diagram of a method according to an embodiment is shown when, after adding an SCG at a base station, mobile data is turned off, there is no data activity / minimal data activity, and a Wi-Fi network is connected to an electronic device.

[0082] The attach request, attach acceptance, and IMS PSN establishment steps may be performed between the electronic device 302 and the MME 312 according to a predetermined procedure. Subsequently, the base station 306 may send configuration information to the electronic device 302 to perform NR measurements and send B1-NR measurement reports. The electronic device 302 may perform NR measurements of the next generation base station 308, and the base station 306 adds the SCG normally. Subsequently, the electronic device 302 receives configuration information for event A2-NR measurement from the gNB 308. The next generation base station 308 requests the A2-NR measurement report from the electronic device 302 via the configuration information to understand the serving cell status / signal strength of the next generation base station 308. In step 508a, the network management system 304 configured in the electronic device 302 may determine at least one state of the electronic device 302 after adding the SCG, such as mobile data being turned off, no data activity / minimal data activity, and connected to a Wi-Fi network in the electronic device 302. If at least one state of the monitored electronic device 302 (such as mobile data is turned off, no data activity / minimal data activity, or connected to a Wi-Fi network in the electronic device 302) is satisfied, the network management system 304 configured in the electronic device 302 attempts to release the added SCG. In step 508b, the network management system 304 configured in the electronic device 302 may send a poor A2-NR measurement report to cause the next generation base station 308 to release the SCG. In step 508c, the next generation base station 308 may release the SCG based on the poor A2-NR measurement report. Subsequently, in step 508d, after causing the next generation base station 308 to release the SCG, the network management system 304 configured in the electronic device 302 limits NR measurements. In step 508e, the network management system 304 configured in the electronic device 302 may detect at least one state of the electronic device 302, such as mobile data is turned on, data activity occurs, or the connection with the Wi-Fi network is disconnected in the electronic device. In step 508f, the network management system 304 configured in the electronic device 302 can enable NR measurement and start NR measurement of the next generation base station 308.

[0083] Figure 5C A timing diagram of a method according to an embodiment is shown when, after SCG addition, mobile data is turned off, no data activity / minimal data activity and a Wi-Fi network are observed to be connected to the electronic device, and no configuration information for event A2-NR measurement is received from a next generation base station.

[0084] The attach request, attach acceptance, and IMS PSN establishment steps may be performed between the electronic device 302 and the MME 312 according to a predetermined procedure. Subsequently, the base station 306 may send configuration information to the electronic device 302 to perform NR measurement and send a B1-NR measurement report. The electronic device 302 may perform NR measurement of the next generation base station 308, and the base station 306 may add the SCG normally. Configuration information about event A2-NR measurement may not be received from the next generation base station 308.

[0085] In step 510a, the network management system 304 configured in the electronic device 302 may determine at least one state of the electronic device 302 after adding the SCG, such as mobile data being turned off, no data activity / minimal data activity, and being connected to a Wi-Fi network in the electronic device. The network management system 304 configured in the electronic device 302 attempts to release the added SCG. In step 510b, the network management system 304 configured in the electronic device 302 may send an SCG fault to cause the next generation base station 308 to release the SCG. In step 510c, the next generation base station 308 may release the NR connection. Subsequently, in step 510d, after releasing the NR connection, the network management system 304 configured in the electronic device 302 limits NR measurements. In step 510e, the network management system 304 configured in the electronic device 302 may detect at least one state of the electronic device 302, such as mobile data being turned on, data activity occurring, or being disconnected from a Wi-Fi network in the electronic device. In step 510f, the network management system 304 configured in the electronic device 302 can enable NR measurement and start NR measurement of the next generation base station 308.

[0086] Figure 6 A method for managing NR communications in an electronic device 302 according to an embodiment is shown.

[0087] like Figure 6 As shown in , method 600 includes one or more blocks illustrating a method for managing NR communications in electronic device 302. Method 600 may be described in the general context of computer-executable instructions, where the computer-executable instructions include routines, programs, objects, components, data structures, procedures, modules, and functions that perform functions or implement abstract data types.

[0088] The order in which method 600 is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement method 600. Furthermore, individual blocks may be deleted from the method without departing from the spirit and scope of the subject matter described herein. Furthermore, method 600 may be implemented in any suitable hardware, software, firmware, or a combination thereof.

[0089] In step 602, method 600 may include receiving configuration information for event B1-NR measurement from a base station. The configuration information may indicate a triggering threshold for triggering the electronic device to send a B1-NR measurement report. The B1-NR measurement report is sent to add an SCG associated with the NR by the base station 306.

[0090] In step 604, the method 600 may include periodically monitoring at least one state of the electronic device after receiving the configuration information. The at least one state of the electronic device includes no mobile data activity, minimal mobile data activity, mobile data disabled, connected to a Wi-Fi network, and frequent NR connection failures during adding the SCG.

[0091] In step 606 , when at least one state of the monitored electronic device 302 is satisfied, the method 600 may include limiting at least one of NR capability and NR measurement of the electronic device 302 .

[0092] Fig. 7A A method for disabling NR if frequent measurement reports are sent to the base station 306 without SCG addition according to an embodiment is shown.

[0093] In step 702, the electronic device 302 is in RRC connection mode with the base station 306. In step 704, the base station 306 sends configuration information for event B1-NR measurement to the electronic device 302. A counter for reporting transmission counts, a waiting timer for waiting a first predetermined time, a timer for timing (watching) a second predetermined time ('Y' minutes), and an iteration factor 'X' are allocated and reset to zero by the network management system 304. In step 706, the electronic device 302 performs B1-NR measurement. In step 708, the electronic device 302 determines whether the NR cell meets the B1 standard. The base station 306 indicates a triggering threshold for triggering the electronic device to send a B1-NR measurement report. Based on the triggering threshold, the electronic device 302 determines whether the NR cell meets the B1 standard. In step 710, if the NR cell meets the B1 standard, the B1-NR measurement report is sent to the base station 306, and if the NR cell does not meet the standard, step 706 is repeated. If the B1-NR measurement report is sent to the base station 306, the counter for the report transmission count is incremented by '1'.

[0094] In step 712, the electronic device 302 determines via the network management system 304 whether the base station 306 has configured the NRSCG. If the base station 306 has configured the NR SCG in step 712, the NR SCG is added in step 716. If the NR SCG is not configured, in step 714, the counter for reporting the transmission count is compared with a predetermined count (such as 5 counts), and the timer is compared with a second predetermined time (such as Y minutes). If the predetermined count and the second predetermined time are less than 5 counts and Y minutes, respectively, step 706 is repeated. If the predetermined count and the second predetermined time are greater than 5 counts and Y minutes, respectively, in step 718, the NR capability of the electronic device 302 is disabled during the waiting timer of the first predetermined time. If, after receiving the event B1-NR configuration, the B1-NR measurement report is sent more than two times or more than 5 counts (i.e., 10 or more reports) or the timer expires more than once (greater than Y minutes), the waiting timer can be iteratively increased.

[0095] In step 720, the electronic device 302 determines via the network management system 304 whether the waiting timer has expired. If the waiting timer has expired, step 706 is repeated, and if not, in step 722, the network management system 304 determines whether the base station 306 configures a new NR cell. In step 724, if a new NR cell is configured, the counter for reporting the transmission count, the waiting timer for waiting the first predetermined time, the timer for timing the second predetermined time ('Y' minutes), and the iteration factor 'X' are reset to zero by the network management system 304, and step 706 is repeated to perform B1-NR measurements and add SCGs. In step 726, if a new NR cell is not configured, the network management system 304 waits for the waiting timer to expire.

[0096] Figure 7B A method for monitoring frequent NR RLF due to transmission power limitation in NR cell edge area according to an embodiment is shown.

[0097] In step 732, the electronic device 302 is in RRC connection mode with the base station 306. In step 734, the base station 306 sends configuration information for event B1-NR measurement to the electronic device 302. In step 736, the electronic device 302 performs B1-NR measurement. In step 738, the electronic device 302 determines whether the NR cell meets the B1 standard. The base station 306 indicates a triggering threshold for triggering the electronic device 302 to send a B1-NR measurement report. Based on the triggering threshold, the electronic device 302 determines whether the NR cell meets the B1 standard. In step 740, if the NR cell meets the B1 standard, a B1-NR measurement report is sent to the base station 306, and if the B1 standard is not met, step 736 is repeated to perform B1-NR measurement.

[0098] In step 742, the base station 306 adds an NR SCG to the electronic device 302. In step 744, the electronic device 302 determines via the network management system 304 whether the electronic device 302 is located in the LTE cell edge area or the NR cell edge area. In step 746, if the electronic device 302 is not in the LTE cell edge area or the NR cell edge area, the electronic device 302 continues LTE as the MCG and NR as the SCG. In step 748, if the electronic device 302 is located in the LTE cell edge area or the NR cell edge area, the network management system 304 can increase the transmission power of the LTE communication relative to the transmission power of the NR communication for VoLTE continuity. For example, the transmission power of the LTE communication is increased to A% or greater, and the transmission power of the LTE communication is B or less. In step 750, since a transmission power greater than the NR transmission power is provided to the LTE communication, the NR RLF is monitored. If NR RLF is encountered in step 750, the counter for the NR RLF count and the timer for the NR RLF time are assigned and incremented by '1' by the network management system 304, and the timer for the NR RLF is assigned and incremented by 1 minute by the network management system 304. In step 752, it is determined whether the NR RLF failure count is less than a predetermined count (such as 5 counts), and it is determined whether the NR RLF failure time is less than a second predetermined time (such as Y minutes). However, the predetermined count of 5 is an example and can be any number of counts required. If it is determined that the NR RLF failure time and the NR RLF failure time are less than the predetermined count and the second predetermined time, respectively, step 736 is repeated to perform B1-NR measurement. In step 754, the NR capability of the electronic device 302 is disabled during the waiting timer of the first predetermined time. If, after receiving the event B1-NR configuration, the B1-NR measurement report is sent more than twice the 5 count (i.e., 10 or more reports) or the timer expires more than once (greater than Y minutes), the waiting timer can be iteratively increased. In step 756, the electronic device 302 determines via the network management system 304 whether the waiting timer has expired. If the waiting timer has expired, step 736 is repeated, and if it has not expired, in step 758, the network management system 304 determines whether the base station 306 configures a new NR cell. In step 760, if a new NR cell is not configured, the network management system 304 waits for the waiting timer to expire. In step 762, if a new NR cell is configured, the counter for reporting the transmission count, the waiting timer for waiting the first predetermined time, the timer for counting the second predetermined time ('Y' minutes), and the iteration factor 'X' are reset to zero by the network management system 304, and step 706 is repeated to add the SCG.

[0099] Figure 7C A method for monitoring frequent NR synchronization failure or NR RACH failure according to an embodiment is shown.

[0100] In step 772, the electronic device 302 is in RRC connection mode with the base station 306. In step 774, the base station 306 sends configuration information for event B1-NR measurement to the electronic device 302. A counter for reporting transmission counts, a waiting timer for waiting a first predetermined time, a timer for timing a second predetermined time ('Y' minutes), and an iteration factor 'X' are allocated and reset to zero by the network management system 304. In step 776, the electronic device 302 performs B1-NR measurement. In step 778, the electronic device 302 determines whether the NR cell meets the B1 standard. The base station 306 indicates a triggering threshold for triggering the electronic device to send a B1-NR measurement report. Based on the triggering threshold, the electronic device 302 determines whether the NR cell meets the B1 standard. In step 780, if the NR cell meets the B1 standard, a B1-NR measurement report is sent to the base station 306, and if not, step 776 is repeated to perform B1-NR measurement. In step 782, the base station 306 adds an RRC reconfiguration with SCG to the electronic device 302, and the predetermined count for reporting the transmission count is incremented by '1'. In step 784, the electronic device 302 monitors via the network management system 304 to determine whether there is an NR synchronization failure or an NR RACH failure. In step 786, if there is no NR synchronization failure or NR RACH failure, the base station 306 adds the SCG. In step 788, the counter for reporting the transmission count is compared with a predetermined count (such as 5 counts), and the timer is compared with a second predetermined time (such as Y minutes). However, the predetermined count of 5 is for exemplary purposes, and the predetermined count can be any number of counts required. If the predetermined count and the second predetermined time are less than 5 counts and Y minutes, respectively, step 776 is repeated. In step 790, if the predetermined count and the second predetermined time are greater than 5 counts and Y minutes, respectively, the NR capability of the electronic device 302 is disabled during the waiting timer of the first predetermined time. If, after receiving the event B1-NR configuration, the B1-NR measurement report is sent more than 5 counts twice or more times (i.e., 10 or more reports) or the timer expires more than once (greater than Y minutes), the waiting timer can be iteratively increased. In step 792, the electronic device 302 determines via the network management system 304 whether the waiting timer has expired. If the waiting timer has expired, step 776 is repeated. In step 794, the network management system 304 determines whether the base station 306 configures a new NR cell. In step 796, if a new NR cell is not configured, the method waits for the waiting timer to expire.In step 798, if a new NR cell is configured, the counter for reporting the transmission count, the waiting timer for waiting the first predetermined time, the timer for timing the second predetermined time ('Y' minutes), and the iteration factor 'X' are reset to zero by the network management system 304, and step 776 is repeated to perform NR measurements and then add SCG.

[0101] Fig. 8A and Figure 8B FIG. 2 shows a comparison of power consumption when performing NR measurement using an electronic device with and without network management according to an embodiment. Fig. 8A In the present invention, when performing NR measurements, the power of the electronic device may consume more (about 320 mA) without using the network management system. By using the network management system of the present disclosure, the power of the electronic device may consume less when performing NR measurements, for example, Figure 8B . The embodiments herein reduce power consumption of electronic devices without performing unnecessary NR measurements that require opening NR-radio frequency (NR-RF) and a protocol stack of the electronic device. The embodiments herein provide optimization of NR (such as 5G) connectivity in non-standalone (NSA) mode to minimize power consumption and frequent data stalls in electronic devices.
