Patent number: 11368895Abstract: A cellular communication network may be configured to use a Long-Term Evolution (LTE) base station and a New Radio (NR) base station to implement a Non-Standalone Architecture (NSA) configuration, in an environment in which the NR base station uses multiple frequency bands that provide respective bandwidths. During an NSA connection with a mobile device, LTE signal strength is used as an indicator of whether the device is within the coverage area of a given NR frequency band. When the LTE signal strength indicates that the device has moved into the coverage area of a frequency band having a higher bandwidth than the currently active NR connection, the device is instructed to release and reestablish its NR connection in order to reconnect using the best available NR frequency band. LTE A1 and/or A5 event measurements may be used to evaluate signal strengths and as triggers for NR release/reestablish operations.Type: GrantFiled: April 10, 2020Date of Patent: June 21, 2022Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Egil Gronstad, Alan Denis MacDonald, Benjamin Sellers

Publication number: 20220046505Abstract: 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.Type: ApplicationFiled: August 9, 2021Publication date: February 10, 2022Inventors: Kun Lu, Boris Antsev, Terri L.

Publication number: 20210377817Abstract: When initiating a Voice-over-IP (VoIP) communication session between an originating device (MO) and a terminating device (MT) on a packet-switched network, network components associated with the MO may encounter a failure when preparing resources for the session, such as a failure to establish a dedicated bearer with the MO. This might typically cause the system to abort the session. Instead, the network components are configured to detect the failure and to initiate a handover to a circuit-switched communication network so that the session may be conducted through the circuit-switched communication network. The failure may be detected by a component of a Long-Term Evolution (LTE) Radio Access Network (RAN) of the network, by a Mobility Management Entity (MME) of the network, or by some other network component. Single Radio Voice Call Continuity (SRVCC) procedures may be used to implement the handover.Type: ApplicationFiled: May 29, 2020Publication date: December 2, 2021Inventors: Kun Lu, Alan Denis MacDonald, Egil Gronstad, Hsin-Fu Henry Chiang, A.

Publication number: 20210337550Abstract: 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. An LTE base station can be configured to broadcast information regarding whether it supports 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 selects a decision value based on the frequency bands that would be used during an NSA session anchored by the LTE base station. The communication device then uses the decision value in combination with the current 4G signal strength to determine whether 5G communications are currently available and whether to display a 5G symbol on the status bar of the communication device.Type: ApplicationFiled: April 22, 2020Publication date: October 28, 2021Inventors: Dinesh Kumar, Ming Shan Kwok, Kun Lu

Patent number: 11076436Abstract: 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.Type: GrantFiled: December 12, 2018Date of Patent: July 27, 2021Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Jun Liu, Christopher H.

Patent number: 11057904Abstract: A connection between mobile terminating (MT) user equipment (UE) and a base station can be established by receiving a paging message at the MT UE from the base station that includes a page reason indicator indicating that the MT UE is being paged for a voice call, and, at least partially in response to receipt of the paging message, sending a Radio Resource Control (RRC) Connection Request message from the MT UE to the base station that includes an establishment cause indicating that the MT UE is requesting a connection with the base station for the voice call. The establishment cause indicating that the MT UE is requesting a connection for a voice call can allow the base station to prioritize the MT UE's RRC Connection Request message over RRC Connection Request messages from other UEs in congested conditions.Type: GrantFiled: December 6, 2017Date of Patent: July 6, 2021Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Neng-Tsann Ueng

Patent number: 11057811Abstract: 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.Type: GrantFiled: December 14, 2018Date of Patent: July 6, 2021Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Ming Shan Kwok, Salvador Mendoza, Alan Denis MacDonald, Jun Liu, Egil Gronstad, Karunakalage Viraj Rakitha Silva, Suresh Thanneeru

Patent number: 11032334Abstract: A method of signaling a reason for a downgrade of an enhanced call to an audio-only call. User equipment (UE) can engage, via a telecommunication network, in an enhanced call including audio content and additional content. The UE can generate a downgrade message that requests a downgrade of the enhanced call to an audio-only call that includes the audio content without the additional content. The downgrade message can include a downgrade reason indicator identifying whether the UE is automatically downgrading the enhanced call or whether the UE is instead downgrading the enhanced call due to user instructions. The UE can send the downgrade message to the telecommunication network.Type: GrantFiled: March 7, 2019Date of Patent: June 8, 2021Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Hsin-Fu Henry Chiang, Satish K.
