Methods, systems, and devices for wireless communications are described. A user equipment (UE) associated with a first subscription and a second subscription may establish a connection with a base station, the first subscription in a connected state. The UE may use the first subscription to perform a communication activity with the base station while the first subscription is in the connected state. Upon completion of the communication activity, the UE may transmit UE assistance information (UAI) to the base station indicating a preference of the UE to switch the first subscription to an inactive state in response to a release message from the base station.

The present application relates to supporting eDRX by a RedCap UE. In an example, a UE indicates to a network that the UE is operating as a RedCap UE and requests an eDRX configuration. In response, the network selects one or more values for the eDRX and sends such value(s) to the UE.

The present invention provides a communication means that enables use of a function for providing connectivity to a local area data network (LADN) in a 5G system (5GS). Furthermore, the present invention provides a communication means that enables use of a function for providing connectivity to an LADN between a user equipment and a network when the use of the function for providing connectivity to an LADN is enabled.

The present invention discloses a mobility management method, a serving GPRS support node or mobility management entity (SGSN/MME), and a terminal to solve the problem of setting or dynamically modifying the mobility management frequency of a particular terminal among numerous terminals. The technical solution of the present invention includes: obtaining subscription data of a terminal, where the subscription data carries periodic update (RAU/TAU) setting information; obtaining a periodic update timer of the terminal according to the periodic update setting information; sending the periodic update timer of the terminal to the terminal; and setting a value that is a little longer than the periodic update timer of the terminal as a mobile reachable timer for monitoring the periodic update of the terminal. The embodiments of the present invention may be applied in low-mobility machine-type communication.

A base station (BS) circuitry, configured to adapt operation of a user equipment (UE) between a stand-alone operation mode and a mobile network operator (MNO) assisted operation mode, includes: a first interface connectable to an MNO network; a second interface connectable to the UE; and a BS controller, configured to: transmit a first register message via the first interface to the MNO network, wherein the first register message indicates a request to operate the UE in at least one licensed frequency band of the MNO network, and signal a hand-over via the second interface to the UE, wherein the hand-over indicates a transition from operating the UE in at least one frequency band of the stand-alone operation mode to operating the UE in the at least one licensed frequency band of the MNO assisted operation mode.

Embodiments of a User Equipment (UE) to support dual-connectivity with a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) are disclosed herein. The UE may receive downlink traffic packets from the MeNB and from the SeNB as part of a split data radio bearer (DRB). At least a portion of control functionality for the split DRB may be performed at each of the MeNB and the SeNB. The UE may receive an uplink eNB indicator for an uplink eNB to which the UE is to transmit uplink traffic packets as part of the split DRB. Based at least partly on the uplink eNB indicator, the UE may transmit uplink traffic packets to the uplink eNB as part of the split DRB. The uplink eNB may be selected from a group that includes the MeNB and the SeNB.
