Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to establish a connection with a core network through a base station configured with mixed core network deployment, wherein the base station is communicatively coupled to each of a LTE core network (CN) such as an evolved packet core (EPC) and a 5G CN. The UE determines a preference for establishing a connection with one of the EPC or the 5G CN based on one or more of a device type of the UE, an active data flow running on the UE, an availability of network slices or packet data unit (PDU) sessions through each core network, or historical network performance of a particular CN. The UE transmits a message to the base station indicating the determined preference. The UE subsequently receives a response from the base station establishing a connection with the indicated preferred core network.

Abstract: A device wirelessly communicating over a wireless network may adjust a threshold from a network-configured value to a new value in response to a performance characteristic of an application executing on the device not meeting a specified metric, for example in response to the application experiencing a latency greater than a specified latency value. The threshold may be associated with a measurement event configured by the wireless network, and the device may use the new value for the threshold when performing measurements on wireless channel conditions of the wireless network. When adjusting the threshold, the device may adjust the threshold once per application session of the application, and/or once per current radio resource control (RRC) connection before the wireless network releases the current RRC connection. Furthermore, the device may adjust the threshold only if the network-configured value associated with the measurement event is greater than a specified threshold value.

Abstract: Apparatuses, systems, and methods for improving efficiency in IMS registration and management in a wireless communication device, such as a UE. In some scenarios, the UE may, while implementing IMS services (e.g. for VoLTE) over a wireless communication link with a cellular network, determine that the wireless communication link is not performing at an acceptable level. In response, the UE may start a timer and buffer IMS SIP signaling messages while the timer is running. If the wireless communication link performance is restored to an acceptable level before expiration of the timer, the UE may transmit the buffered IMS SIP signaling messages. If the timer expires prior to restoration of the wireless communication link, the buffered messages may be cleared, and the UE may locally deregister from IMS registration and IMS PDN. In some scenarios, select IMS SIP signaling messages may be omitted or removed from the buffer.
