A user communications device having active and idle states operates in a cellular communications network in which user communications devices communicate via network communications devices of cells of the network. History data identifying the cells in which the user communications device has been present whilst in the idle state is maintained. This history data is used by the user communications device or by a network communications device to enable adjustment of cell selection/reselection parameters for the user communications device in the active state.

A radio unit (RU) in a directional communication network establishes a connection with a first antenna among two antennas of a first TE in a first moving object that first enters a serving duration of the RU according to a network access request from the first antenna, and when receiving the network access request from a second antenna among two antennas of a second TE in a second moving object that next enters the serving duration, the RU processes the network access request from the second antenna based on network access priority of the second antenna and network access priority of the first antenna to which the connection is established.

A method including a first network element receiving first information reported by a first terminal device. The first information is used to indicate parameter information of an exception when the first terminal device accesses a first cell. The first network element determines configuration information based on the first information. The configuration information includes configuration information for accessing the first cell. The first network element sends the configuration information.

A wireless device sends, to a base station, at least one first radio resource control (RRC) parameter comprising at least one first identifier indicating at least one first closed access group (CAG) of a first cell. The at least one first RRC parameter is associated with a connection with the base station via the first cell. The wireless device receives at least one second RRC parameter comprising at least one second identifier indicating at least one second CAG that the wireless device is allowed to access. The wireless device selects a second cell associated with the at least one second CAG. The wireless device transmits a random access preamble via the second cell.

The present invention belongs to the field of communications, and discloses a cell handover method and a device. The method includes: determining, by a first base station to which a primary carrier cell belongs and according to a measurement report sent by user equipment UE, whether soft handover needs to be performed for the UE; if soft handover needs to be performed for the UE, transferring, by the first base station, a radio bearer RB between the first base station and the UE to a second base station to which a secondary carrier cell belongs; and selecting, by the first base station, a target cell according to the measurement report, and handing over the UE to a target base station to which the target cell belongs. The present invention can avoid service interruption caused when cell handover is performed for UE.

Embodiments of the present disclosure disclose a mobility management procedure initiation method and a device, where the method may include: when a quantity N of failures of a mobility management procedure initiated by a device to a core network entity is greater than or equal to a first threshold, determining, by the device, whether N pieces of failure information include first information used to indicate a failure in establishing a radio resource control protocol connection; when the device determines that the N pieces of failure information include the first information, setting, by the device, an initiation condition parameter for initiating the mobility management procedure; and initiating, by the device, the mobility management procedure based on the initiation condition parameter. The present disclosure can improve a network access speed of the device.

In a cellular communication system, a coverage area configuration transition is performed where a compensation service area is expanded to cover at least a portion of an energy saving service area of an energy saving cell employing the same frequency channel as the compensation service area. An energy saving communication station providing the energy saving cell is configured to deactivate the energy saving service area. Handovers to the compensation service area are prepared for the UE devices in the energy saving service area. The energy saving communication station sends a expansion notification to a compensation communication station where the notification at teas!indicates that the compensation service area can be expanded. The energy saving communication station transmits handover commands to the UE devices prior to expansion of the compensation service area and reduction of the energy saving service area.

A method of a network node for changing a first frequency of a first original cell, wherein one or more wireless communication devices are served by the original cell, and wherein the network node controls a plurality of other cells. The method comprises selecting one or more second frequency of an unlicensed spectrum that the network node should switch the original cell to, determining a second cell on the selected one or more second frequency as target cell and causing the target cell to maintain the same neighbor cell relations as the original cell. The method also comprises moving the one or more wireless communication devices from the original cell to the target cell, turning off the original cell when the one or more wireless communication devices have been moved from the original cell to the target cell and informing one or more neighboring network nodes of the frequency change to the one or more second frequency. Also disclosed is a computer program product, an arrangement and a network node.
