Methods and apparatus, including computer program products, are provided for handovers including fallbacks. In some example embodiments, there is provided an apparatus comprising at least one processor and at least one memory including program code which when executed causes the apparatus to at least: receive, during creation or modification of a bearer, a message including a handover threshold based at least in part on a type of codec for the bearer; receive, from a user equipment, a measurement report providing an indication of a condition of the bearer and/or perform a measurement, by the base station, providing the indication of the condition of the bearer; determine, based at least on the handover threshold, whether to initiate a handover. Related apparatus, systems, methods, and articles are also described.

A method includes receiving cell reselection information from a radio access network device. The cell reselection information includes an identifier of at least one carrier frequency, an identifier of a network slice supported by each of the at least one carrier frequency, and priority information corresponding to the identifier of the network slice that is information of a specific service type of the network slice or a network slice set identifier corresponding to the network slice. The method further includes in response to the terminal device performing cell reselection, selecting a cell on a carrier frequency of the network slice supported by the terminal device as a reselected to-be-camped cell based on the identifier of the at least one carrier frequency, the identifier of the network slice supported by each of the at least one carrier frequency, and priority information corresponding to the identifier of the network slice.

The present disclosure provides a network slice reselection method, including: receiving a message sent from a network side for a currently selected network slice, and reselecting a network slice; and a reason carried by the message is insufficient resource. The present disclosure further provides a network slice reselection device, an electronic device and a computer-readable storage medium.

An apparatus for wireless communication of a UE is disclosed. The apparatus may initiate, at a new radio (NR) serving cell, a voice session with an IMS. The apparatus may perform, in response to determining that voice over NR (VoNR) is not supported by the first NR cell, an EPS fallback procedure to establish the voice session with the IMS. The apparatus may update a whitelist of NR cells that support VoNR to include the first NR cell when it is determined that the first NR cell supports VoNR.

Embodiments include methods for a UE to perform mobility operations in a wireless network based on conditions related to data traffic. Such methods include receiving, from a network node, one or more conditional reconfigurations. Each includes a reconfiguration message associated with a candidate target cell and one or more execution conditions that need to be fulfilled to apply the reconfiguration message when performing a mobility operation, including at least one first execution condition related to UE data traffic and/or to one or more UE applications. Such methods include monitoring for the execution conditions in the conditional reconfigurations and based on detecting fulfillment of one or more execution conditions in a particular conditional measurement configuration, performing a mobility operation towards the candidate target cell associated with the reconfiguration message in the particular conditional measurement configuration. Other embodiments include complementary methods by a network node, as well as UEs and network nodes

The present disclosure provides an information transmission method, an information reception method and apparatuses. The information transmission method includes: recording, by a UE, information related to CHO and/or CPC; and transmitting, by the UE, the information related to the CHO and/or CPC to a network.
