Fig. 2 is a schematic flow chart of an Xn interface based switching flow, and as shown in fig. 2, the entire switching flow can be divided into three phases:

the handover preparation phase (201-205) may include:

in 201, the source base station triggers the terminal device to perform neighbor cell measurement, so that the terminal device can measure the neighbor cell and report the measurement result to the source base station.

Specifically, the source base station may send measurement configuration information to the terminal device through RRC connection reconfiguration, which may specifically include the following:

1. measuring object (Measurement Object)

With the frequency point as a basic unit, each configured measurement object is an independent frequency point and has an independent measurement object Identification (ID), and for the same-frequency and different-frequency measurement, the measurement object can be a single carrier frequency. Cells associated with the carrier frequency, or a cell Offset (Offset) list and a blacklisted cell list may also be configured. No operations are performed on the blacklisted cells in the measurement evaluation and measurement report.

2. Reporting configuration (measurement report config)

Each reporting configuration has an independent Identification (ID), and the event triggering reporting configuration includes an event type and a threshold value, and a duration (Time to Trigger) satisfying a triggering condition. The reporting configuration of the periodic trigger type comprises a reporting period and a periodic trigger purpose.

In an LTE system, the same frequency/different frequency measurement events include the following:

event A1: the channel quality of the serving cell is above an absolute threshold (absolute threshold);

event A2: the channel quality of the serving cell is below an absolute threshold;

event A3: the channel quality of the serving cell is higher than the channel quality of the primary cell/primary secondary cell (PCell/PSCell) by a specific offset (offset);

event A4: the channel quality of the neighbor cell (neighbor) is higher than an absolute threshold;

event A5: the channel quality of the PCell/PSCell is below an absolute threshold 1 and the channel quality of the neighbor cell/secondary cell (SCell) is above an absolute threshold 2;

event A6: the channel quality of the neighbor cell is higher than that of the SCell by offset;

event B1: the channel quality of the neighbor cell (neighbor) is higher than an absolute threshold;

event B2: the channel quality of the PCell is below the absolute threshold 1 and the channel quality of the neighbor cell is above the absolute threshold 2.

In 202, the source base station evaluates the measurement result reported by the terminal device and decides whether to trigger handover.

If the source base station decides to trigger a handover in 203, a handover request may be sent to the target base station.

In 204, after receiving the handover request sent by the source base station, the target base station may start admitting according to the service information carried by the source base station, and perform radio resource allocation.

In 205, the target base station sends a handover request confirm message to the source base station, and returns the admission result and radio resource configuration information in the target base station to the source base station. The handover preparation phase is thus completed.

The handover execution phase (206-208) may include:

in 206, after receiving the handover request acknowledgement message of the target base station, the source base station may trigger the terminal device to perform handover.

In 207, the source base station may forward the buffered data, the incoming data packet, the system sequence number of the data, etc., to the target base station. And, the target base station may buffer data received from the source base station

Furthermore, the terminal device may disconnect from the source base station and establish synchronization with the target base station.

In 208, the terminal device synchronizes to the target base station. The handover execution phase is completed.

The handover complete phase (209-212) may include:

in 209, the target base station sends a path switch request to the mobility management function (Access and Mobility Management Function, AMF).

In 210, after the AMF receives the path switching request from the target base station, the AMF performs path switching with the user plane function (User Plane Function, UPF) to clear the path flag of the user plane of the source base station.

After the path switching is completed, the AMF may send a path switching acknowledgement message to the target base station in 211.

In 212, the target base station sends a terminal device context release message to the source base station, informs the source base station that the handover is successful, and triggers the source base station terminal device context. So far, the handover is completed.

Non-terrestrial communication network (Non Terrestrial Network, NTN) technology based on 5G NR is currently being studied, where the NTN technology generally provides communication services to terrestrial users by means of satellite communication, and with respect to terrestrial cellular network communication, satellite communication is not limited by the region of the user, and for general terrestrial communication, areas where communication devices cannot be set up or are not covered due to rarity of population, can be covered by satellites, and satellites can orbit around the earth, so that basically every corner on the earth can be covered by satellite communication. In a satellite communication scenario, where the satellite is typically far from the UE, the signal propagation delay between the satellite and the UE is large.

The existing cell switching mechanism is that the network equipment determines a target cell according to a measurement event reported by the UE, however, for a scenario of switching from an NTN cell to a terrestrial communication network (Terrestrial Network, TN) cell, i.e. a conventional LTE cell or NR cell, or switching from a TN cell to an NTN cell, the UE should preferably access the TN cell, based on the existing switching mechanism, the UE may try to access the NTN cell in the coverage area of the TN, resulting in ping-pong switching, and bringing about a larger transmission delay, and affecting user experience.

Fig. 3 is a schematic flow chart of a method 200 for wireless communication according to an embodiment of the present application. The method 200 may be performed by a terminal device in the communication system shown in fig. 1, and as shown in fig. 3, the method 200 may include at least part of the following:

s210, the terminal equipment receives measurement configuration information of the network equipment, wherein the measurement configuration information comprises measurement reporting conditions, and the measurement reporting conditions are used for switching between a first type cell and a second type cell;

and S220, the terminal equipment determines a cell for reporting the measurement according to the measurement reporting condition.

Alternatively, in some embodiments, the first type of cell and the second type of cell are different types of cells, and as an example, the first type of cell may be a TN cell, for example, an LTE cell or an NR cell, and the second type of cell may be an NTN cell, for example, a satellite cell. Hereinafter, a first type cell is taken as a TN cell, and a second type cell is taken as an NTN cell, but the present application is not limited thereto.

In the embodiment of the application, the network equipment can configure the measurement reporting condition of switching between the TN cell and the NTN cell for the terminal equipment, that is, when switching between the TN cell and the NTN cell, the measurement reporting condition is met to report the measurement of the cell.

In the embodiment of the application, the measurement report condition can control the terminal equipment to report the NT cell preferentially, and the NTN cell is selected to report under the condition that no resident NT cell exists, so that the network equipment can select the NT cell preferentially as the target cell accessed by the terminal equipment when carrying out cell selection based on measurement report of the terminal equipment.

Hereinafter, the details of the measurement report condition will be described with reference to the embodiment.

Example 1:

the measurement report condition may include a first measurement event, where the first measurement event may be a newly added measurement event, and the newly added measurement event may be used for measurement report when handover is performed between a TN cell and an NTN cell.

In some embodiments, the first measurement event is used to indicate that the channel quality of a neighbor cell of the terminal device is better than the channel quality of a serving cell of the terminal device.

The service cell of the terminal equipment is a TN cell, and the neighbor cell of the terminal equipment is an NTN cell, and is marked as a scene 1, namely a scene of switching from the TN cell to the NTN cell; or the service cell of the terminal equipment is an NTN cell, the neighbor cell of the terminal equipment is a TN cell, and the neighbor cell is marked as a scene 2, namely a scene of switching from the NTN cell to the TN cell; alternatively, the embodiment may be applied to other scenarios where at least one of the serving cell and the neighbor cell is an NTN cell.

In some embodiments, the first measurement event comprises:

the channel quality of the neighbor cell of the terminal device is higher than the channel quality of the serving cell of the terminal device by a specific offset,

if the serving cell is a first type cell, the neighboring cell is a second type cell, and the specific offset is a first offset and corresponds to scenario 1; or alternatively

If the serving cell is a second type cell, the neighboring cell is a first type cell, and the specific offset is configured as a second offset, corresponding to scenario 2.

In the embodiment of the application, the first offset is configured to be larger than the second offset, that is, a higher offset can be configured for measurement reporting of the scene 1, a lower offset can be configured for measurement reporting of the scene 2, and compared with the scene of switching from a TN cell to a NTN cell, the requirement on the channel quality of the NTN cell is higher, in other words, the requirement on the channel quality of the TN cell is lower in the scene of switching from the NTN cell to the TN cell, in other words, the terminal equipment is easier to switch from the NTN cell to the TN cell and is harder to switch from the NT cell to the NTN cell, thereby increasing the probability that the terminal equipment resides in the TN cell, reducing the probability that the terminal equipment resides in the NTN cell, avoiding the ping-pong effect caused by switching into the NTN cell, and the transmission delay and the transmission interruption caused by switching into the NTN cell.

Optionally, in some embodiments, the first offset is preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

Alternatively, in some embodiments, the second offset may be preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

In some embodiments of the present application, the first offset may be greater than the offset in measurement event A3, and the second offset may be less than the offset in measurement event A3.

In other embodiments, the first measurement event comprises:

the channel quality of the neighbor cell of the terminal equipment is higher than a first threshold value, and the channel quality of the service cell of the terminal equipment is lower than a second threshold value, wherein the service cell is a first type cell, namely the terminal equipment currently resides in a TN cell;

the channel quality of the neighbor cell of the terminal device is higher than a third threshold value, and the channel quality of the serving cell of the terminal device is lower than a fourth threshold value, wherein the serving cell is a second type cell, that is, the terminal device currently resides in an NTN cell.

In the embodiment of the present application, the first threshold may be configured to be greater than the third threshold, and the second threshold may be smaller than the fourth threshold, that is, when the terminal device resides in the TN cell, the requirement on the channel quality of the neighboring cell is higher, and when the terminal device resides in the NTN cell, in other words, the requirement on the channel quality of the neighboring cell is lower, and the terminal device more easily resides in the TN cell and is more easily migrated from the NTN cell, so that the probability that the terminal device resides in the TN cell can be increased, the probability that the terminal device resides in the NTN cell can be reduced, and the ping-pong effect caused by accessing the NTN cell and the transmission delay and the transmission interruption caused by accessing the NTN cell can be avoided.

In some embodiments of the present application, the first threshold may be greater than the absolute threshold 1 in the measurement event A5 and the second threshold may be less than the absolute threshold 2 in the measurement event A5; the third threshold value is less than the absolute threshold value 3 in the measurement event A5, and the fourth threshold value may be greater than the absolute threshold value 2 in the measurement event A5.

Alternatively, in some embodiments, the first threshold may be preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

Alternatively, in some embodiments, the second threshold may be preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

Alternatively, in some embodiments, the third threshold may be preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

Alternatively, in some embodiments, the fourth threshold may be preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

Example 2:

the measurement report condition includes a second measurement event and a trigger condition, wherein the second measurement event indicates that the channel quality of a neighboring cell of the terminal device is better than the channel quality of a serving cell of the terminal device, and the trigger condition is used for indicating whether a first type cell around the serving cell of the terminal device is camping.

Alternatively, the second measurement event may be an existing measurement event, for example, measurement event A3 or measurement event A5, etc. Alternatively, the first measurement event in embodiment 1 may be the first measurement event, which is not limited in this embodiment of the present application.

In this embodiment 2, the terminal device may further determine whether a trigger condition is satisfied if the second measurement event is satisfied, and perform measurement reporting of the cell again if the trigger condition is satisfied.

In the embodiment of the present application, the triggering condition may be used to indicate whether the first type of cells surrounding the serving cell of the terminal device are camping, that is, when the cell handover between the TN cell and the NTN cell is performed, in the case that the second measurement event is satisfied, the terminal device may further combine whether the first type of cells surrounding the serving cell of the terminal device are camping, so as to determine whether to perform measurement reporting of the cells.

Case 1: if the serving cell of the terminal device is a TN cell, the neighbor cell of the terminal device is an NTN cell, and the channel quality of the serving cell and the neighbor cell satisfies the second measurement event, in this case, the terminal device may further determine whether the TN cells around the serving cell of the terminal device may reside, and determine whether to report the measurement of the cell.

For example, if none of the TN cells surrounding the serving cell of the terminal device can reside, it is determined to perform measurement reporting of the cell, and further information of the NTN cell, for example, measurement results and/or identification information of the NTN cell, may be reported to the network device.

For another example, if a cell that can reside in a TN cell surrounding a serving cell of the terminal device exists, the terminal device may determine not to report measurement of the cell, or may also determine to report measurement of the cell, and further may report information of the cell that can reside, for example, measurement results and/or identification information of the cell that can reside, to a network device.

Case 2: if the serving cell of the terminal device is an NTN cell, the neighbor cell of the terminal device is an NTN cell, and the channel quality of the serving cell and the neighbor cell satisfies the second measurement event, in this case, the terminal device may further determine whether the TN cells around the serving cell of the terminal device may reside, so as to determine whether to report measurement of the cell.

For example, if none of the TN cells surrounding the serving cell of the terminal device can reside, it is determined to perform measurement reporting of the cell, and further information of the neighboring cell, for example, measurement results and/or identification information of the neighboring cell, may be reported to the network device.

For another example, if a cell that can reside in a TN cell surrounding a serving cell of the terminal device exists, the terminal device may determine to report measurement of the cell, and may further report information of the cell that can reside, for example, measurement result and/or identification information of the cell that can reside, to a network device.

Case 3: if the serving cell of the terminal device is an NTN cell, the neighbor cell of the terminal device is a TN cell, and the channel quality of the serving cell and the neighbor cell satisfies the second measurement event, in this case, as an example, the terminal device determines to perform measurement reporting of the cell, and may further report information of the neighbor cell, for example, measurement results and/or identification information of the neighbor cell, to the network device; as another example, the terminal device may further determine whether a TN cell surrounding the serving cell of the terminal device is camping or not to determine whether to perform measurement reporting of the cell.

For another example, if a cell that can reside in a TN cell surrounding a serving cell of the terminal device exists, the terminal device may determine to report measurement, further determine a candidate cell to report in the neighboring cell and the cell that can reside, and further report information of the candidate cell, for example, measurement result and/or identification information of the candidate cell, to a network device.

By way of example and not limitation, the TN-cells surrounding the serving cell of the terminal device may not reside including the channel quality of the TN-cells surrounding the serving cell of the terminal device being below a certain threshold;

the TN cells around the serving cell of the terminal device may reside in a cell that may include a channel quality existing in the TN cells around the serving cell of the terminal device that is greater than or equal to a specific threshold.

It will be appreciated that the specific threshold may be preconfigured or configured by the network device, e.g. may be configured to the terminal device by measuring configuration information.

Example 3:

the measurement report condition includes a third measurement event, which may include the second measurement event in embodiment 2 and the trigger condition in embodiment 2, unlike the foregoing embodiment, that is, the second measurement event and the trigger condition in embodiment 2 may be combined into one measurement event, and further implementation will not be described in detail herein with reference to the related description in embodiment 2.

Therefore, in the embodiment of the application, the network device can configure the triggering condition of the second measurement event in addition to the second measurement event, so that the terminal device can further judge whether the triggering condition is met or not under the condition that the second measurement event is met, and trigger the measurement report of the cell under the condition that the triggering condition is met, thereby being beneficial to ensuring that the terminal device preferentially reports the TN cell under the condition that the TN cell is covered, and further avoiding the ping-pong effect caused by accessing the NTN cell, and the transmission delay and the transmission interruption caused by accessing the NTN cell.

Fig. 4 is a method of wireless communication according to another embodiment of the present application, as shown in fig. 4, the method 300 may include the following:
