  • Patent number: 11985536
    Abstract: In some aspects, the present disclosure relates to a method for performing packet flow description (PFD) management, the method including establishing a Quality-of-Service (QoS) flow between a user equipment (UE) and a core network (CN) for a data flow of an application, creating, by the UE, a UE-requested packet flow description (PFD) upon a change in the data flow, sending, from the UE to the CN, a request to the CN for updating a CN PFD to an updated PFD using the UE-requested PFD, receiving, at the UE from the CN, a downlink (DL) packet mapped to the QoS flow using the updated PFD.

  • Patent number: 11765574
    Abstract: A method, device, computer readable storage medium and integrated circuit for providing user equipment (UE) capability information to a network. The method includes receiving a request from a network for radio access capabilities of the UE, determining a first plurality of band combinations that the UE is capable of utilizing for communications with the network, determining a number of band combinations that are to be included with a message generated in response to the request, ordering the plurality of band combinations into a prioritized order of band combinations based on at least one priority factor, generating the message that includes the radio access capabilities, wherein the message includes a second plurality of band combinations that are based on the prioritized order and the number of band combinations that are to be included with a message and transmitting the message to the network.

  • Publication number: 20230098218
    Abstract: Systems, methods, and devices are described to facilitate soft signaling between a user equipment (UE) and a network element. A UE and a network element can exchange HTTP or Websocket messages to identify and request network resources needed for the UE to access and use application services. The network element can use requested network resources to cause the configuration of a connection between the UE and a radio access network.

  • Patent number: 11540185
    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to prioritize cells that support EN-DC over similar cells not supporting EN-DC. The UE may be configured to perform one or more measurement scans associated with cell selection and/or cell re-selection and may determine whether at least two LTE cells meet a selection criteria based on RSRP and/or SNR measurements. The UE may be configured to, in response to determining that at least two LTE cells meet the selection criteria, prioritize a first LTE cell of the at least two LTE cells over a second LTE cell of the at least two LTE cells based, at least in part, on support EN-DC. The first LTE cell may indicate support of EN-DC, e.g., via a ULI IE included in a SIB2 broadcast by the first LTE cell. The UE may be configured to select the first LTE cell for camping.

  • Publication number: 20200304984
    Abstract: Apparatuses, systems, and methods for a dual subscriber identity module (SIM) dual standby (DSDS) capable user equipment (UE) devices to perform data operations with a first SIM that is not capable of or preferred for packet switched (PS) services and a second SIM that is capable of or preferred for PS services. A timer may be initiated upon radio frequency (RF) chain handover from the first SIM to the second SIM, whereupon a first connection associated with the first SIM is maintained in an idle state while the timer is running. Upon expiration of the timer, the UE may determine whether to send a scheduling request to maintain or release the first connection. The timer may be utilized when a call is dropped over the first connection, to increase the likelihood of successfully receiving a callback. The timer may be shortened in duration to reduce reception of spam messaging.
