Provided are methods of controlling charging for a user equipment (UE), and a communication device. One of the methods includes: in response to a measurement report of a UE, a source base station determining a target base station for the UE; and sending wireless charging information of the UE to the target base station.

The present invention provides user equipment and a method for ensuring continuous service reception in a wireless network. User equipment (UE) obtains configuration information of a neighboring cell; the UE determines that at least two cells of all cells including the serving cell and the neighboring cell belong to a same area to which a same multimedia broadcast multicast service belongs; and during measurement of a reference signal, the UE combines reference signal measurement values of at least two cells that belong to the area of the same multimedia broadcast multicast service to obtain a combined measurement value, and compares the combined measurement value with a measurement value of another cell, so as to determine whether to perform reselection. Therefore, in a handover determining process, radio signal quality of a single cell is prevented from being underestimated, so that an unnecessary handover procedure is avoided, thereby ensuring quality of a radio signal obtained by UE.

Methods and apparatus are provided for aggressive beam selection during a handover procedure. A User Equipment (UE) measures a plurality of candidate downlink beams of a target base station (BS), wherein measurement opportunities for each of the candidate downlink beams are scheduled periodically. The UE reports measurements relating to one or more of the measured candidate downlink beams to a source BS. The UE receives a command to handover to the target BS, and in response to receiving the command, attempts to find a new downlink beam of the target BS having a corresponding measurement opportunity that is earlier than a next measurement opportunity of one of the one or more candidate downlink beam.

A communication control method in a relay station that holds a donor base station list, is connected to a donor base station existing on the donor base station list, and performs relay transmission between the donor base station and a user terminal, comprises a step A of designating a neighboring base station, a step B of inquiring the neighboring base station designated in the step A of whether to accept or refuse the relay station, and a step C of updating the donor base station list in response to an inquiry result in the step B.

An electronic device may include: a communication circuit configured to support cellular communication through a terrestrial network and a non-terrestrial network, a memory configured to store mapping data obtained by mapping identification information of the non-terrestrial network and a service supported by the non-terrestrial network, and at least one communication processor. One or more of the at least one communication processor may be configured to: search for a cell corresponding to another network within a specified distance with reference to a location of the electronic device, based on the non-terrestrial network having a highest priority with respect to communication connection, determine, based on another network having a lower priority than the non-terrestrial network being found, whether an emergency call is supported on another network having the lower priority, and perform, based on the emergency call being supported on another network having the lower priority, camp-on on another network having the lower priority, wherein the camp-on includes monitoring, by the electronic device, system information and paging information in a newly selected cell based on cell reselection.

Mobility management methods, apparatuses, and base stations are provided. The method includes that, in response to setting up an inter-base station interface with a neighboring base station, a new radio unlicensed (NR-U) base station independently deployed in an unlicensed spectrum in a 5G new radio (NR) system sends a request message to the neighboring base station, where the request message requests to obtain unlicensed spectrum support capability information of the neighboring base station. Further, the NR-U base station determines response information of the neighboring base station to the request message and performs mobility management on user equipment in a serving cell according to the response information.

A method of operating a terminal includes receiving, from a source cell, a radio resource control (RRC) reconfiguration message including a list of a plurality of first objects in a measurement order, reordering the list of the plurality of first objects based on handover information to obtain a reordered list, the handover information corresponding to a connection history of the terminal, sequentially measuring the plurality of first objects based on the reordered list to obtain a measurement result; and transmitting a measurement report to the source cell based on the measurement result.

Techniques for dynamic optimization of radio access network sites are provided. A wireless communications infrastructure identifies that a piece of user equipment (UE) is connected to a base station associated with a current Radio Access Network (RAN) site that does not have sufficient backhaul resources to support the piece of UE. A target RAN site that has sufficient backhaul resources to support the piece of UE is identified. The target RAN site associated with at least one base station. A Radio Frequency (RF) signal transmitted from at least one of the base station associated with the current RAN site and the at least one base station associated with the target RAN site is modified. The modification causes the piece of UE to handover from the base station associated with the current RAN site to the at least one base station associated with the target RAN site.

A base station can perform various methods for supporting a secondary node (SN) procedure. In one example, a first base station, operating as (i) a source SN. (ii) a target SN, or (iii) a candidate SN for the SN procedure, performs a method including: communicating a message with a second base station, operating as a master node (MN), to perform the SN procedure; and determining, based on whether the SN procedure is a conditional procedure or a non-conditional procedure, whether to start a timer in response to the communicating.

A method and apparatus for a slice-aware cell barring in a wireless communication system is provided. The wireless device performs a first cell reselection procedure with slice-aware cell barring, by considering a specific cell as barred, based on the network slice information, until at least one barring release condition is met. Based on the at least one barring release condition is met, the wireless device release the specific cell from being barred.
