Furthermore, multiple systems may be combined (for example, LTE or LTE-A combined with 5G) for application.

[0187] First, the related technologies of the present disclosure are described:

[0188] When a UE selects or reselects a cell, it must follow the corresponding rules. For example, when a UE reselects a cell, it must follow the S criterion. Specifically, the S criterion is:

[0189] Srxlev>0 and Squal>0,

[0190] Among them, Srxlev is the cell selection level, and Squal is the cell selection quality.

[0191] The cell selected or reselected by the UE needs to meet the S criterion.

[0192] Where Srxlev = Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp ,

[0193] Squal=Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset temp .

[0194] When the S criterion is met, the UE can perform cell selection and reselection, and cell reselection and selection require measurement of the serving cell or neighboring cells. The UE can determine when to measure neighboring cells based on the above S criterion.

[0195] The UE uses the following rules to limit the required measurements:

[0196] For intra-frequency measurements, if the serving cell satisfies Srxlev>SIntraSearchP and Squal>SIntraSearchQ, the UE may not perform intra-frequency measurements; otherwise, the UE shall perform intra-frequency measurements. SIntraSearchP is the Srxlev threshold (in dB) for the specified intra-frequency measurement, and SnonIntraSearchQ is the Squal threshold (in dB) for the specified intra-frequency measurement.

[0197] The UE shall apply the following rules to the NR inter-frequencies and inter-RAT frequencies indicated in the system messages, with the UE having the priority defined in the existing protocols:

[0198] - For NR inter-frequencies or inter-RAT frequencies with a reselection priority higher than the reselection priority of the current NR frequencies, the UE shall perform measurements on the higher priority NR inter-frequencies or inter-RAT frequencies according to existing schemes.

[0199] - For NR inter-frequencies with a reselection priority equal to or lower than the reselection priority of the current NR frequency, and for inter-RAT frequencies with a reselection priority lower than the reselection priority of the current NR frequency:

[0200] - If the serving cell satisfies Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, the UE may not perform measurement on NR inter-frequency cells of the same priority or lower priority, or NR inter-frequency cells of lower priority; otherwise, the UE shall perform measurement on NR inter-frequency cells of the same priority or lower priority, or NR inter-frequency cells of lower priority according to the protocol;

[0201] The protocol stipulates that TN cells can also broadcast SIB19, so that UEs in TN cells can also use SIB19 information to assist UEs in measuring neighboring cells of NTN.

[0202] The TN cell may broadcast SIB19, which carries NTN neighbor cell configuration, such as NTN configuration, frequency, cell ID and other information.

[0203] Then, when the UE's serving cell is a TN cell, considering the movement of the satellite, there is no NTN neighboring cell at certain times, but according to the existing protocol, the UE will also measure the frequency of the NTN network and read the content of SIB19.

[0204] Therefore, when the UE's serving cell is a TN cell, if the neighboring cells configured for the TN cell include NTN cells or NTN cell frequencies, even if no NTN neighboring cells exist at certain times, the UE will measure the NTN cell frequencies according to the aforementioned measurement criteria, or the UE will also need to obtain SIB19, resulting in unnecessary NTN neighboring cell measurements and unnecessary SIB19 readings. When the UE's serving cell is an NTN cell, considering the non-continuous satellite coverage, at certain times, there may be no NTN neighboring cells on a certain frequency, resulting in unnecessary measurements on that frequency. In view of the above situation, how to avoid unnecessary measurements to reduce terminal power consumption is an urgent problem that needs to be solved.

[0205] The solution provided by the embodiment of the present disclosure provides a measurement determination method, which enables the terminal to determine whether to measure the frequency associated with the time information based on the specified time information. If the UE's serving cell is a TN cell, the UE can also determine whether to obtain the system message SIB19 based on the specified time information, thereby avoiding unnecessary measurements and effectively reducing the power consumption of the terminal.

[0206] In some embodiments, time may include at least one of a moment, a combination of a moment and a duration, and a time period.
