摘要: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

摘要: Systems and methods for extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to an Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.

摘要: A device, system and method for a user equipment (UE) to opportunistically utilize the wireless capabilities of a paired device. The UE is configured to establish a first cellular network connection based on a first subscription, a second cellular network connection based on a second subscription and a connection to a further UE based on a short-range communication protocol. The UE identifies a predetermined condition and transmits an indication to the further UE based on the predetermined condition. The further UE establishes a further cellular network connection in response to the indication and the further cellular network connection is based on one of the first subscription or the second subscription. The UE then declares no service for one of the first cellular network connection or the second cellular network connection based on the further cellular network connection.

摘要: The present disclosure relates to opportunistically selecting an antenna in an electronic device having multiple antennas. A baseband processor of the electronic device may connect to a first cellular tower providing cellular service at a first frequency using a first antenna of the electronic device. The baseband processor may then receive an indication of a handover event to a second cellular tower operating at a second frequency. The baseband processor may determine signal measurements of the second cellular tower for each antenna of the electronic device that is capable of operating at the second frequency. The baseband processor may execute a handover to the second cellular tower using the antenna associated with the best performing signal measurements. In this manner, an antenna may be opportunistically selected based on performance of the antenna, improving operation of the electronic device and quality of cellular service.

摘要: A method to control measurement messaging is performed at a mobile wireless device. The mobile wireless device transmits a first measurement message to a radio access network in a wireless network and stores the first measurement message pending receipt of an acknowledgement from the radio access network. Before receiving the acknowledgement to the first measurement message, the mobile wireless device determines at least one parameter included in the first measurement message requires updating. The mobile wireless device deletes the stored pending first measurement message and transmits a second measurement message to the radio access network including an updated value for the at least one parameter in the first measurement message.

摘要: Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.

摘要: Apparatuses, systems, and methods for enhancement of Wi-Fi calling for DSDS user equipment devices (UEs). The UE may register a first connection supported by a first SIM with IMS for VoWiFi based on a determination to prefer VoWiFi for the first SIM. The first SIM may be associated with a first subscription to a first RAN. The UE may include a second SIM that may be associated with a second subscription to a second RAN. The UE may register a second connection associated with the second SIM with the IMS for VoWiFi and/or VoLTE and initiate/receive, via the first connection supported by the first SIM, a VoWiFi call. A recommendation to handover the VoWiFi call from Wi-Fi to cellular data may be received and, based, at least in part, on the recommendation, the UE may register a second connection associated with the second SIM for IWLAN over cellular data.

摘要: Apparatuses, systems, and methods for a wireless device to perform detection and mitigation of data stalls. The mitigation may occur during and/or at initiation of a data connection. The wireless device may establish a data connection(s) with a network over a Wi-Fi or cellular interface and monitor the data connection(s) for a data stall condition(s)/hint(s). The wireless device may perform a remedial action(s) responsive to detection of a data stall condition(s)/hint(s), including initiating a service recovery of the cellular interface, initiating a radio access technology (RAT) upgrade procedure, and/or initiating a handover procedure to a neighbor cell.
