Fig. 1 shows a schematic diagram of a mobile communication system according to an embodiment of the present application. The mobile communication system may include: a network device 10 and a terminal device 20.

The network device 10 is a device for providing wireless communication services to the terminal device 20. A connection may be established between the network device 10 and the terminal device 20 over an air interface, such that communication, including interaction of signaling and data, is performed over the connection. The number of network devices 10 may be plural, and two adjacent network devices 10 may communicate with each other by wired or wireless means. The terminal device 20 can switch between different network devices 10, i.e. establish a connection with different network devices 10.

In one example, as shown in fig. 2, for example, a non-terrestrial communication network (Non Terrestrial Network, NTN), the network device 10 in the NTN may be a satellite 11. One satellite 11 may cover a range of ground areas and provide wireless communication services to terminal devices 20 on the ground areas. In addition, the satellites 11 can orbit the earth, and communication coverage of different areas of the earth surface can be achieved by arranging a plurality of satellites 11.

Satellite communications have many unique advantages over terrestrial cellular communication networks. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous Orbit) satellites, HEO (High Elliptical Orbit ) satellites, and the like according to the difference in Orbit heights. LEO and GEO are the main studies at the present stage.

LEO; the low orbit satellite has a height ranging from 500km to 1500km and a corresponding orbit period of about 1.5 hours to 2 hours. The signal propagation delay for single hop communications between users is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the user terminal is not high. GEO; geosynchronous orbit satellites have an orbit height of 35786km and a period of 24 hours around the earth. The signal propagation delay for single hop communications between users is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

In another example, as shown in fig. 3, a cellular communication network is illustrated in which network device 10 may be a base station 12. Base station 12 is a device deployed in an access network to provide wireless communication functionality for terminal equipment 20. The base stations 12 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. The names of network device-capable devices may vary in systems employing different Radio access technologies, for example in 5G NR (New Radio) systems, called gnob or gNB. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the terminal device 20 with the wireless communication function are collectively referred to as a network device. In addition, the terminal device 20 according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), mobile Station (MS), terminal devices (terminal devices), and so on. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal device. In addition, in the embodiments of the present application, the terms "network" and "system" are commonly used in combination, but those skilled in the art will understand the meaning.

In the related art, the satellites in fig. 2 are largely classified into a transparent repeating (Transparent Payload) satellite and a regenerative repeating (Regenerative Payload) satellite. Fig. 4 shows a schematic diagram of a transparent forwarded satellite network architecture, with a terminal (UE) connected to a 5G base station (Next Generation Node B, gndeb or gNB) via an NR universal User network interface (User to Network interface Universal, uu). The transparent forwarded satellite and NTN Gateway (GW) form a remote radio unit (Remote Radio Unit, RRU), the gNB and RRU form a radio access Network (Radio Access Network, RAN), the gNB is connected to a 5G Core Network (CN) through an NG interface, and the 5G CN is connected to a Data Network (DN) through an N6 interface.

Fig. 5 shows a schematic diagram of a satellite network architecture for regenerative forwarding, where a terminal (UE) is connected to the gNB through an NR Uu. The regenerated and forwarded satellite takes on the function of gNB, gNB is connected with a 5G Core Network (CN) through an NG interface on a satellite broadcast interface (Satellite Radio Interface, SRI), and 5G CN is connected with a Data Network (DN) through an N6 interface.

When the LEO satellite moves at high speed, the connection between the satellite and the GW needs to be switched, and fig. 6 shows a schematic diagram of the feed link switching performed by the satellite. GW1 and GW2 may be connected to two corresponding gnbs, or may be connected to two cells (cells) under one gNB. The gNB may be a complete gNB or a Centralized Unit (CU). All UEs in the satellite covered area need to be handed over from the original cell to the new cell after feeder link handover (Feeder Link Switch). If GW1 and GW2 are connected to two cells under one gNB, the UE is theoretically not required to perform a handover operation.

The mode of feeder link switching includes: soft handoff (Soft Switch) and Hard handoff (Hard Switch).

For soft handoff, fig. 7 shows a schematic diagram of soft handoff performed by a satellite, where the time when a new feeder link connection is established is earlier than the time when an old feeder link connection is disconnected, i.e., the satellite establishes the new feeder link connection first and then disconnects the old feeder link connection.

At time T1, a feeder link exists only between the satellite and GW 1. As the satellite moves, the satellite approaches the transition threshold, a feeder link handoff is imminent, and at time T2, the satellite begins to establish a feeder link connection with GW 2. At time T3, the satellite only has a feeder link with GW1, and the satellite disconnects the feeder link with GW 1. I.e. during the period from time T2 to time T3, the satellite simultaneously maintains the feeder link connection with GW1 and GW 2.

For hard handoff, fig. 8 shows a schematic diagram of a satellite performing hard handoff, where the time of establishing a new feeder link connection is later than the time of disconnecting an old feeder link connection, i.e., the satellite disconnects the old feeder link first and then establishes a new feeder link connection.

Before time T1, a feeder link exists only between the satellite and GW 1. As the satellite moves, the satellite approaches the switching threshold, the satellite switches the feeder link at time T1, disconnects the feeder link with GW1 at time T1, and establishes the feeder link with GW2 at time T2. I.e. the satellite has no feeder link connection in the period from time T1 to time T2.

Taking the fifth generation mobile communication technology (5th Generation,5G) as an example, when deployed early in NR, complete NR coverage is difficult to obtain, typical network coverage is wide area long term evolution (Long Term Evolution, LTE) coverage and island coverage mode of NR. A large amount of LTE is deployed below 6GHz, and there is little spectrum below 6GHz available for 5G. In order to protect mobile operators from early investment in LTE, a mode of tight interworking (Tight Interworking) between LTE and NR is proposed. Taking long term evolution-new air interface dual link (LTE-NR Dual Connectivity, EN-DC) as an example, fig. 9 shows a schematic diagram of an EN-DC network architecture. With LTE as MN and NR as SN. The MN is primarily used to implement RRC control functions and control plane to the CN, and the SN is used to configure secondary signaling, e.g., third radio signaling bearers (Signaling Radio Bearer, srb 3), primarily to provide data transfer functions.

The Primary Cell of the MN is called Primary Cell (PCell), the Secondary Cell of the MN is called Secondary Cell (SCell), and all cells associated with the MN belong to a Primary Cell group (Master Cell Group, MCG). The primary Cell of the SN is called primary Secondary Cell (Primary Secondary Cell, PSCell), the Secondary Cell of the SN is called Secondary Cell (SCell), and all cells associated with the SN belong to a Secondary Cell group (Secondary Cell Group, SCG). Fig. 10 shows schematic diagrams of MCG and SCG structures.

Next, a description will be given of a condition-based PSCell change (Conditional PSCell Change, CPC) and a condition-based PSCell addition (Conditional PSCell Addition, CPA):

aiming at the problem that frequent PScell change exists in a high-speed moving scene and a high-frequency deployment scene, the basic principle of CPC is that target cell information is distributed to UE in advance, the UE evaluates according to the configuration conditions of a network side, and when the configuration conditions are met, the UE initiates the PScell change.

For CPC, a plurality of candidate target cells may be configured for the UE, and a configuration condition of CPC may be configured for each candidate target cell, respectively, and the configuration condition of CPC for each candidate target cell may include 1 or more trigger events. Exemplary configuration conditions for the CPC include at least one of the following:

the signal quality of the neighbor Cell is higher than the signal quality of a Special Cell (SpCell) than the first threshold; the signal quality of the SpCell is below a first threshold and the signal quality of the neighbor cell is above a second threshold. Among them, spCell includes PSCell and PCell.

For the CPA, a plurality of candidate target cells may be configured for the UE, and the configuration conditions of the CPA may be configured for each candidate target cell, respectively. Exemplary configuration conditions for the CPC include at least one of the following:

The signal quality of the adjacent cell is higher than a first threshold; the signal quality of the inter-technology neighbor cell is above a first threshold.

Taking NR as an example, the measurement events supported by NR include:

a1 event: the signal quality of the serving cell is higher than a first threshold; a2 event: the signal quality of the serving cell is below a first threshold; a3 event: the signal quality of the neighbor cell is higher than that of the SpCell by a first threshold; a4 event: the signal quality of the adjacent cell is higher than a first threshold; a5 event: the signal quality of the SpCell is lower than a first threshold, and the signal quality of the neighbor cell is higher than a second threshold; a6 event: the signal quality of the neighbor cell is higher than the signal quality of the SCell by a first threshold; b1 event: the signal quality of the different technology neighbor cell is higher than a first threshold; b2 event: the signal quality of the PCell is below a first threshold and the signal quality of the neighbor cells of the different technology is above a second threshold.

For activation and/or deactivation of SCG, the following conclusions exist in the related art:

the supporting MN indicates activation and/or deactivation of SCG through RRC signaling, and the non-supporting SN indicates deactivation of SCG. When the SCG is in a deactivated state, the UE does not listen to the physical downlink control channel (Physical Downlink Control Channel, PDCCH) on the PSCell, does not transmit the physical uplink control channel (Physical Uplink Control Channel, PUCCH) on the PSCell, and does not transmit the channel sounding reference signal (Sounding Reference Signal, SRS) on the PSCell. When the SCG is in the deactivated state, the UE still performs measurements on the SCG based on the MN or SN configuration. The MN or SN or UE may request SCG activation. The MN or SN may request SCG deactivation. The UE may indicate to the MN that it is desired to deactivate SCG. The network may control whether the UE is allowed to transmit the indication information through the configuration related information.

The following describes the technical solution of the present application through several embodiments.
