Abstract:
Generating and using a device-type specific preferred public land mobile network (PLMN) list for roaming PLMN selection. Wireless devices sharing one or more common characteristics may be tasked with collecting roaming PLMN selection data. That data may be collected and used to generate a preferred PLMN list specific to wireless devices sharing those common characteristics. The preferred PLMN list may be distributed to wireless devices sharing those common characteristics, which may then use it in conjunction with roaming PLMN selection.
Abstract:
Avoiding conflicts between radio access technologies (RATs) in a device configured to operate according to multiple RATs. The device may be operated in a discontinuous reception (DRX) mode according to each of a first RAT and a second RAT using a shared radio. It may be determined that a conflicting wakeup time is scheduled according to DRX cycles of the first and second RATs. A subscriber identity of the device may be changed in response to determining that a conflicting wakeup time is scheduled according to DRX cycles of the first and second RATs.
Abstract:
A method for delaying network reselection by a wireless communication device following a call failure is provided. The method can include determining an initiation of a voice call while connected to a first network. The method can further include participating in a circuit switched fallback (CSFB) procedure to transition from the first network to a second network in response to initiation of the voice call. The method can additionally include determining an occurrence of a call failure of the voice call. The method can also include, responsive to the call failure, barring reselection to the first network for a threshold barring period.
Abstract:
Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE transmits a connection request message to a base station over a first network using the first SIM, where the connection request message includes one or more capability indications of the UE. The UE receives a connection accept message from the base station, where the connection accept message includes one or more network capability indications corresponding to respective UE capability indications of the one or more UE capability indications. The UE performs communications with the base station according to the one or more network capability indications.
Abstract:
Devices and associated methods for operating a dual-subscriber identity module (SIM) dual-standby (DSDS) user equipment device (UE) configured with a first SIM and a second SIM. The UE performs communications with a first cellular network using the first SIM and a first radio resource control (RRC) connection, and receives a request to perform a higher priority communication using the second SIM. In response to the request to perform the higher priority communication, the UE transmits a request to the first network to suspend the first RRC connection. After transmission of the request to suspend the first RRC connection, the UE receives a message from the first network to place the first RRC connection in an inactive state, and initiates a timer, wherein the timer is used to determine whether the first RRC connection remains in the inactive state or transitions to an idle state.
Abstract:
Techniques discussed herein can facilitate inactive state transmissions for a Base Station (BS) via a 4-step or 2-step inactive state RACH process. One example aspect is a BS including communication circuitry and one or more processors communicatively coupled to the communication circuitry and configured to cause the BS to transmit a radio link quality threshold and an uplink data size for a Radio Resource Control (RRC) inactive data transmission. Receive a Random Access Channel (RACH) preamble in response to the radio link quality threshold and the uplink data size being satisfied. Receive the RRC inactive data transmission, and transmit a RACH message in response to receiving the RRC inactive data transmission.
Abstract:
Methods and devices for selecting an edge application server (EAS) to service a user equipment (UE). One exemplary method incudes determining that a current protocol data unit (PDU) session of an application being executed by a UE is being serviced by a first EAS, determining that the first EAS is no longer suitable to service the application, selecting a second EAS to service the application and instructing the UE to use the second EAS for future PDU sessions for the application.
Abstract:
Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.
Abstract:
This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.
