A communication device is a communication device that communicates with at least one of a plurality of ground stations via a non-geostationary satellite, and includes: an acquisition unit that acquires predetermined information necessary for switching a connection destination ground station in advance before switching processing; and a communication control unit that switches the connection destination ground station based on the predetermined information.

In a network operating system, a consumed resource manager of a slicing control device manages a resource consumed by a base station. A terminal information manager manages a type of terminal and a service in use. A cell manager manages cell information and creates a neighbor cell list. A movement information acquirer acquires movement information suggesting motion of a terminal. A motion predictor predicts, on the basis of the movement information, a future position or motion of the terminal. A resource controller and sets aside the resource in advance.

A method includes determining, by a source base station, based on at least one of a measurement report received from a terminal device and a mobility trajectory of the terminal device, a prepared cell list that includes a set of cells where the terminal device is capable of handover. The method includes sending at least one required context for the handover to the set of cells in the prepared cell list. The method also includes receiving acknowledgement from the set of cells. The method further includes sending a handover complete message, which contains the prepared cell list, to the terminal device, wherein the prepared cell list provides a capability for the terminal device to make a number of handovers when the terminal device is within a coverage area of the set of cells.

A reporting method includes: a user equipment (UE) providing computation capability resource assistance information of the UE to a network device. The computation capability resource assistance information may be carried in a MAC control element (MAC CE) or radio resource control (RRC) signaling, and the computation capability resource assistance information of the UE may be provided to the network device through a control channel carrying the MAC CE or the RRC signaling.

This disclosure relates to techniques for performing conditional handovers and cell re-selections along known routes. A cellular base station may select a conditional handover set for a wireless device. The conditional handover set may include information for multiple conditional handovers. The wireless device may receive the conditional handover set. The wireless device may perform conditional handover to at least a first cell indicated in the conditional handover set based at least in part on the conditional handover set.

A communication method includes a terminal device having a dual-card function that obtains, passing through a target section and from a network device, network status information of the target section through which the terminal device is about to pass, and determines, in advance based on the network status information, a target subscriber identity module (SIM) card used when the terminal device passes through the target section. Subsequently, before or when the terminal device passes through the target section, the terminal device can switch to the target SIM card in advance for communication.

Embodiments of this application provide a cell handover method and apparatus. A first network device of a first cell obtains user information of a terminal device, and then the first network device may determine handover information based on the user information and running information of the first network device, so that after the first network device sends an RRC message including the handover information to the terminal device, the terminal device may perform N consecutive cell handovers based on the handover information. In the N cell handovers, the first network device only needs to obtain the user information once, to configure handover conditions for the N subsequent handovers in advance at a time. This simplifies a network signaling procedure, reduces network overheads, and reduces handover response time. The embodiments of this application are applicable to a network handover in a satellite scenario.

An embodiment of a user equipment supports conditional handovers to one or more cells of a cellular network.

The user equipment is configured to receive configuration data from the cellular network. The configuration data indicates for a plurality of target cells of the cellular network, conditions to trigger a conditional handover to any of the target cells.

The user equipment is further configured to check the conditions with respect to appliance, and, in case of appliance, trigger the conditional handover.

Among other things there is disclosed a method for determining corrected load values. The method includes obtaining a set of input features, each input feature being one of: i) a reported load value that was reported by a target base station to a source base station and ii) a derived load value derived using the reported load value; obtaining a set of output features, each output feature being a determined load value determined by the source base station, wherein each output feature is associated with a single one of the input features; and determining, using the set of input features and the set of output features, a set of one or more parameters for a mathematical model for determining a corrected load value based on one or more load values provided by the target base station.
