  • Publication number: 20200196211
    Abstract: When using Dual Connectivity in a Non-Standalone Architecture cellular communication system, a data bearer may be steered through a Long-Term Evolution (LTE) base station or a New Radio (NR) base station. Each bearer is assigned a combination of Quality of Service (QoS) values corresponding to the service type that the bearer is supporting. For example, each different service type may be assigned a combination of a QoS Class Identifier and an Allocation and Retention Priority parameter value. Each combination is also associated with a radio access technology such as LTE radio access technology or NR radio access technology. When NR communications are available between a network core and a communication device, and if the bearer's combination of QoS values has been associated with NR, bearer data is routed through an NR base station. Otherwise, the bearer data is routed through the LTE base station.

  • Patent number: 10687287
    Abstract: A cellular communication device is configured to use Non-Standalone Architecture (NSA) dual connectivity for communicating with a cellular communication network, using simultaneous 4th-Generation (4G) Long-Term Evolution (LTE) and 5th-Generation (5G) New Radio (NR) radio access technologies. When implementing NSA dual connectivity, the device may receive separate transmit power control commands for LTE uplink transmissions and NR uplink transmissions, respectively. In order to keep total transmitted power of the device below a regulatory maximum transmit power, LTE transmit power is limited to a value that is less than regulatory maximum transmit power, thereby reserving at least a reserved transmit power for NR transmissions. This allows NR acknowledgements to be sent from the device to avoid NR downlink failure.

  • Publication number: 20200068638
    Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. During idle mode, a communication device may scan 5G RF frequencies to determine whether a 5G signal is available and whether to display a 5G network symbol in the status bar of the device. The communication device is configured to detect conditions indicating whether a user of the device is likely viewing the device and/or the display of the device. If it is unlikely that the user is viewing the device or its screen, RF frequency scanning is paused to reduce power consumption and the currently displayed network symbol is maintained until RF frequency scanning is resumed.

  • Publication number: 20200068468
    Abstract: A first access node of a first wireless access network receives, via a first entry node of the first network, a service-request message from a terminal registered with the first network. The first access node requests first network-capacity information associated with the first wireless access network from the first entry node, and second network-capacity information associated with a second wireless access network from a second access node of the second network. The first access node selects a target access network based on the service-request message and the first and second network-capacity information. The first access node, in response to a selection of the first wireless access network, sends a service-reply message to the first entry node. The first access node, in response to a selection of the second wireless access network, triggers a handover of the terminal to the second wireless access network.

  • Publication number: 20200068456
    Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network, configured to in a 5G Non-Standalone Architecture (NSA). When using NSA, a primary communication link is established through the 4G network and a secondary communication link is established through the 5G network. When a 5G secondary link is present, a communication device displays a 5G symbol to indicate 5G network availability. When a secondary link failure occurs, the device is configured to display a 4G network for a time period, regardless of whether other measures indicate that 5G services may be available. When a connection goes from connected mode to idle mode, the communication device displays the 5G symbol for a time period if a 5G secondary link was present at the time when entering idle mode, and otherwise displays a 4G symbol during the time period.

  • Publication number: 20200022200
    Abstract: A cellular communication network may be configured to use a primary Long-Term Evolution (LTE) base station and a secondary New Radio (NR) base station to implement a Non-Standalone Architecture (NSA) configuration. The primary LTE base station broadcasts system information, for reception by the communication device, using System Information Blocks (SIBs). The secondary NR base station, however, may be configured to not broadcast certain system information. Rather, system information of the NR base station is specified to the communication device in communications from the LTE base station during setup of an NR data connection. When there is a change in the system information of the NR base station, the network is configured to forgo updating the communication device with the new system information at least until the existing NR data connection is terminated.

  • Publication number: 20190379469
    Abstract: A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. The 4G network is accessed through Long-Term Evolution (LTE) base stations. The 5G network is accessed through New Radio (NR) base stations. LTE base stations are configured to broadcast information regarding 5G availability. For example, an LTE base station may indicate whether it is configured to support Non-Standalone Architecture (NSA) Dual Connectivity in conjunction with an associated NR base station. When a communication device receives an indication that NSA Dual Connectivity is available, the communication device scans and measures signal strengths on each of multiple frequencies that are potentially being used by the NR base station. This can be done without decoding of the signals. If a signal having a sufficient signal strength is found, the communication device displays a 5G symbol in its status bar.

  • Publication number: 20190320474
    Abstract: A core network element, such as a PCRF and/or an MME, can determine that a Quality of Service (QoS) Class Indicator (QCI) of particular bearer set up between the core network and user equipment (UE) should be changed to a new QCI. When a control node, such as the MME, determines that no teardown delay conditions are met, the control node can send a bearer release message to a base station that instructs the base station to tear down all bearers for the UE, even if they are in use. In a dual connectivity arrangement, such as a E-UTRAN New Radio-Dual Connectivity (EN-DC) configuration, the base station can instruct a secondary base station to also release all bearers for the UE. The control node can instruct the base station to reestablish the particular bearer with the new QCI when the base station reestablishes the bearers for the UE.

  • Publication number: 20190223070
    Abstract: An access network can allocate a bearer for a network service associated with a quality-of-service (QoS) value (QV) and a retention-priority value (RPV), and determine a bearer ID for the service based on the QV, the RPV, and a supplemental priority value (SPV) different from the QV and from the RPV. Upon handover of a terminal, session(s) carried by a bearer allocated by the terminal can be terminated. That bearer can be selected using IDs of the bearers and a comparison function that, given two bearer IDs, determines which respective bearer should be terminated before the other. Upon handover of a terminal to an access network supporting fewer bearers per terminal than the terminal has allocated, a network node can select a bearer based on respective QVs and RPVs of a set of allocated bearers. The network node can deallocate the selected bearer.
