Abstract: This application relates to communication methods and communication apparatuses. In an example method, a terminal device or a chip in the terminal device obtains first information. The first information is used to determine an access range corresponding to a first signal. In response to determining that the terminal device is located in the access range after a first moment, the terminal device or the chip in the terminal device sends a first random access preamble. The first random access preamble is associated with the first signal.

Abstract: Before a network jitter occurs, a server receives operation instructions from an electronic device, generates a plurality of first rendering instruction streams based on the operation instructions, sends the plurality of first rendering instruction streams to the electronic device, and generates and stores one or more first rendering contexts for one or more first rendering instruction streams in the plurality of first rendering instruction streams. When the network jitter occurs, the server generates a second rendering instruction stream based on received operation instructions, and generates and stores a second rendering context based on the second rendering instruction stream. After the recovery from the network jitter, the server sends a set of rendering context differences to the electronic device. In this way, network transmission traffic after the recovery from the network jitter is reduced, transmission and processing delays are also reduced, and user experience is improved.

Abstract: A handover method and apparatus are disclosed. In some implementations, the method includes: determining a part of terminal devices to be handed over in a plurality of terminal devices in a staring area of a first beam; sending a first handover request message to a target satellite, where the first handover request message includes contexts of the part of terminal devices; and receiving a handover instruction sent by the target satellite based on the first handover request message, and sending the handover instruction to the part of terminal devices by using the first beam. The handover instruction includes handover parameters used for handing over the part of terminal devices. According to some implementations, the part of terminal devices in the plurality of terminal devices in the staring area may be handed over, so that a signaling storm can be avoided and communication performance can be improved.

Abstract: The present disclosure relates to communication methods and communication apparatuses. In one example method, a first communication apparatus receives first configuration information, where the first configuration information includes first identification update information and information about a first update moment of a first cell of a second communication apparatus, and the first identification update information is used to determine first identification information used by the first cell at the first update moment or after the first update moment. The first communication apparatus communicates based on the first configuration information by using the first identification information at the first update moment or after the first update moment, where the first communication apparatus is in a coverage range of the first cell.

Abstract: This application provides a handover method and apparatus in satellite communications. The handover method in satellite communications in this application includes: obtaining, by a terminal device, ephemeris information of first satellite base stations, where the first satellite base stations are satellite base stations that cover the terminal device; determining, by the terminal device based on the ephemeris information, a destination satellite base station to which the terminal device needs to hand over; determining, by the terminal device based on the determined destination satellite base station, a first time at which the terminal device is to hand over to the destination satellite base station; and handing over, by the terminal device based on the determined first time, to a destination cell served by the destination satellite base station. This application reduces power consumption of the terminal device, saves air interface resources, and further avoids a signaling storm caused because a large quantity of terminal devices report measurement information at the same moment, thereby increasing a handover success rate.

Abstract: This application provides a data packet processing method and apparatus, applied to a satellite communications system. An earth surface, space, and network space are divided based on a satellite constellation and an ephemeris of a satellite, and an identifier is allocated to each ground area, each space area, and each network that are sub-divisions of the earth surface, space and network space, to establish a fixed mapping relationship between the EID, the SID, and the NID. In addition, each satellite maintains mapping relationship information recording the mapping relationship. Unless a satellite joins the constellation or one satellite leave service, the mapping relationship recorded in the mapping relationship information does not need to be updated. Based on the mapping relationship information, a satellite may route a data packet, thereby reducing a large amount of signaling interaction caused by establishing and maintaining a routing table in the conventional manner.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and a communication apparatus, to resolve a problem of a poor interference suppression effect caused by closing an edge beam of a satellite. The method includes: A first satellite sends a first message to a second satellite. The first message includes information about a frequency reuse scheme. The information about the frequency reuse scheme includes basic unit information. The basic unit information includes central point locations and frequency information of at least N−1 beams. Herein, N is a frequency reuse factor of the first satellite. At least N−1 different pieces of frequency information exist in the frequency information that is of the at least N−1 beams and that is included in the basic unit information. In addition, N is a positive integer greater than or equal to 3.

Abstract: 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.
