[0046] An embodiment of the present disclosure provides a method for transmitting measurement gap configuration information. Referring to Fig. 2, Fig. 2 is a flowchart of a method for transmitting measurement gap configuration information shown in an exemplary embodiment. As shown in Fig. 2, the method includes the following steps S21 to S25.

[0047] Step S21: the user equipment 101 sends auxiliary information to the network device 102 of the serving network, the auxiliary information instructing the user equipment 101 at least one parameter for switching from the serving network to the target network.

[0048] Step S22, the network device 102 receives auxiliary information sent from the user equipment 101 for determining at least one parameter for the UE to switch from the serving network to the target network.

[0049] Step S23: the network device 102 determines first measurement gap configuration information based on the auxiliary information.

[0050] In step S24, the network device 102 transmits the first measurement gap configuration information to the user equipment 101.

[0051] In step S25, the user equipment 101 receives the first measurement gap configuration information sent from the network device 102, which is determined by the network device based on the auxiliary information.

[0052] In an embodiment of the present disclosure, the user equipment 101 reports related parameters for switching from a service network to a target network, and the network device 102 determines first measurement gap configuration information based on the related parameters for service network switching. The network device can instruct the user equipment 101 on the timing for switching from the service network to the target network and measuring the related parameters based on the first measurement gap configuration information, so that the user equipment 101 can measure the related parameters and transmit services on the service network at different times, thereby mitigating service interruption issues during the service network switching process.

[0053] In this method, the network device 102 can determine corresponding first measurement gap setting information based on the relevant parameters for switching from the service network to the target network reported by the user equipment 101, thereby accurately instructing the user equipment 101 on the timing of parameter measurement during the service network switching process, so that the user equipment 101 can properly and effectively perform service transmission of the service network during the non-parameter measurement time during the service network switching process, and improve the service interruption problem during the network switching process.

[0054] In one possible implementation, the parameter may be first measurement interval configuration information proposed by the user equipment 101. In another possible implementation, the parameter may be one or more parameters that determine the first measurement gap configuration information in cooperation with the network device 102. In this manner, the network device 102 can determine the first measurement interval configuration information based on a communication protocol and one or more parameters reported by the user equipment 101. Alternatively, the network device 102 may determine the first measurement interval configuration information based on one or more parameters reported by the user equipment 101.

[0055] Note that the above embodiment includes user equipment 101 and network device 102, and the steps performed by each of the user equipment 101 and network device 102 are described in detail in any one of the following embodiments, and will not be described in detail here.

[0056] An embodiment of the present disclosure provides a method for receiving measurement gap configuration information, which is performed by the user equipment 101. The method includes the following steps:

[0057] In step S1-1, the user equipment 101 transmits auxiliary information to the network device 102, the auxiliary information instructing the user equipment 101 on at least one parameter for switching from the serving network to the target network.

[0058] In step S1-2, the user equipment 101 receives the first measurement gap configuration information sent from the network device 102 and determined by the network device 102 based on the auxiliary information.

[0059] In some possible embodiments, the service data transmission of the user equipment 101 in the serving network is not affected by the same-frequency target cell measurement of the serving cell. If the target cell and the serving cell are not on the same frequency, the user equipment 101 needs to suspend service communication with the serving network during the process of switching from the serving network to the target network. The time during which the service communication with the serving network is suspended to perform measurement operations related to the target cell in the target network is the measurement gap.

[0060] The first measurement gap configuration information may instruct the user equipment 101 to correspond to information related to the measurement gap (Meas Gap). For example, the first measurement gap configuration information may include at least one of a start time, an end time, and a duration. Here, the start time or the end time may be an offset relative to the current time or a predetermined time. For example, the first measurement gap configuration information may include a start time and a duration, or may include a start time and an end time, or may include an end time and a duration, or may include only a start time, or may include an end time, or may include a duration. During the duration of the indicated measurement gap (Meas Gap), the user equipment 101 can measure a target cell in the target network. The network device 102 of the serving network does not schedule service data to the user equipment 101 during the duration of the measurement gap, thereby effectively alleviating the problem of service interruption during network switching.

[0061] In some possible embodiments, the process of the user equipment 101 switching from the serving network to the target network may involve one of the following measurement operations: inter-frequency measurement, inter-system measurement, receiving system information (SI) or paging information, etc.

[0062] In one example, the auxiliary information may be used to indicate the use of the measurement gap (Meas Gap), i.e., to indicate which specific measurement operation is to be performed.

[0063] In one example, the auxiliary information indicates at least one of the following parameters: A measurement gap (Meas Gap) identifier (ID) for identifying the corresponding auxiliary information. For example, each auxiliary information may correspond to one Meas Gap ID. Measurement Gap Type indicates whether the Gap in the corresponding auxiliary information is periodic or aperiodic. A periodic measurement gap may be used periodically according to a fixed cycle, while an aperiodic measurement gap may be released after one use. Timing difference of the measurement gap. Measurement Gap Purpose: Each auxiliary information can indicate one measurement purpose or purpose corresponding to the measurement gap, such as cell measurement (inter-frequency measurement or inter-system measurement), receiving system information (SI) or paging information, or receiving or transmitting service data of the target network. Validity information of the measurement gap (Meas Gap), for example, indicating the valid time length or valid usage count of the gap in the corresponding auxiliary information.

[0064] In one example, the auxiliary information may include multiple groups of information, each group of information containing the same parameters, and each group of information corresponding to a unique group identifier.

[0065] In the embodiment of the present disclosure, the user equipment 101 reports auxiliary information, so that the network device 102 determines more accurate first measurement gap configuration information based on the auxiliary information, and the user equipment 101 performs measurement operations related to the target network in the appropriate measurement gap based on the first measurement gap configuration information, and performs service transmission of the service network at another appropriate time, thereby effectively alleviating the service interruption problem during the network switching process.

[0066] The method of the above embodiment further includes transmitting radio resource control signaling including the assistance information to the network device 102 of the serving network.

[0067] In an embodiment of the present disclosure, the user equipment 101 reports the assistance information to the network device 102 via Radio Resource Control (RRC) signaling.

[0068] An embodiment of the present disclosure provides a method for receiving measurement gap configuration information, which is performed by the user equipment 101. The method further includes the following steps:

[0069] In step S1-1', the user equipment 101 sends auxiliary information instructing the user equipment 101 on at least one parameter for switching from the serving network to the target network, and second measurement gap configuration information to the network device 102 of the serving network.

[0070] In step S1-2', the user equipment 101 receives the first measurement gap configuration information sent from the network device 102 and determined by the network device 102 of the serving network based on the auxiliary information and the second measurement gap configuration information.

[0071] The second measurement gap configuration information indicates the measurement gap configuration information requested by the network device 102 to the user equipment 101. Here, the second measurement gap configuration information may include at least one of a start time (gapoffset), an end time, and a time length (gapduration). Alternatively, the second measurement gap configuration information may include at least one of a start time (gapoffset), a time length (gapduration), and a measurement gap period (gapperiod).

[0072] Each of the start time or end time may be an offset relative to the current point in time or a predetermined point in time.

[0073] In one possible embodiment, the measurement gap duration indicates the duration of the measurement gap requested by the user equipment 101. For example, in response to the target network being a new wireless network, the measurement gap duration is the maximum value of the synchronization signal measurement time setting SMTC or the maximum value of the reference signal measurement time setting CMTC. Alternatively, in response to the target network being a long-term evolution network, the measurement gap duration is the duration of the cell reference signal.

[0074] In one possible example, the target network is a 5G New Radio Network (NR), and the gap duration required for the user equipment 101 to perform 5G NR signal measurements may be the maximum value of SMTC (SMTC_max), which is the maximum value of SMTC configured on all target carriers corresponding to the target cell in 5G NR.

[0075] In one possible example, the target network is a 5G New Radio Network (NR), and the gap duration required for the user equipment 101 to perform 5G NR signal measurements may be a maximum value of CMTC (CMTC_max), which may be the maximum value of CMTC configured for all target carriers corresponding to the target cell in 5G NR.

[0076] In one possible example, the target network is a Long Term Evolution network (LTE), and the gap duration required for the user equipment 101 to make LTE signal measurements may be the duration of the reference signal of the target cell.

[0077] In one possible embodiment, the network device 102 determines first measurement gap configuration information based on the auxiliary information and second measurement gap configuration information requested by the user equipment 101, and the gap duration in the first measurement gap configuration information is less than or equal to the gap duration in the second measurement gap configuration information.

[0078] In an embodiment of the present disclosure, the network device 102 determines the first measurement gap configuration information based on the auxiliary information and the second measurement gap configuration information requested by the user equipment 101, thereby more accurately determining the first measurement gap configuration information, which is advantageous for the user equipment 101 to obtain a more appropriate measurement gap.

[0079] An embodiment of the present disclosure provides a method for receiving measurement gap configuration information, which is performed by the user equipment 101. The method includes steps S1-1 and S1-2, or steps S1-1' and S1-2'.

[0080] In the method, the auxiliary information includes first information indicative of a timing difference between a serving cell in the serving network and a target cell in the target network.

[0081] In some possible embodiments, the network device 102 needs to know a timing difference when determining the first measurement gap configuration information. The timing difference may characterize the maximum timing difference (deltaT_max) between a reference timing serving cell in the serving network and a target cell in the target network, and may be a System Frame Number (SFN) and frame timing deviation (SFN and Frame boundary Timing Difference (SFTD)).

[0082] In one example, after the network device 102 obtains the first information, it sets a measurement gap based on the first information, and can ensure that the user equipment 101 performs target cell measurement of the target network in the set gap, thereby effectively measuring the target cell and avoiding the problem of the target cell not being measured.

[0083] In one possible example, the auxiliary information is first information, and the first information corresponds to a timing difference of t1-n, where n=1 or 2.

[0084] An embodiment of the present disclosure provides a method for receiving measurement gap configuration information, which is performed by a user equipment 101. The method includes steps S1-1 and S1-2, or steps S1-1' and S1-2'.

[0085] In this method, the auxiliary information includes first information indicating a timing difference between a serving cell in the serving network and a target cell in the target network, and second information indicating whether the type of measurement gap is periodic or aperiodic.

[0086] In one possible embodiment, in response to the type indicated by the second information being periodic, the measurement gap period in the first measurement gap setting information is an integer multiple of the maximum value of the SMTC period or an integer multiple of the maximum value of the CMTC period of the target carrier in the target network.

[0087] In some possible embodiments, if the measurement gap type is periodic, the second measurement gap configuration information further includes a measurement gap period (gapperiod). The first measurement gap configuration information determined by the network device 102 based on the second measurement gap configuration information and the auxiliary information also includes the measurement gap period (gapperiod).

[0088] In one example, the measurement gap period is T_gap, the maximum value of the SMTC period is T_SMTC_max, the maximum value of the CMTC period is T_CMTC_max, and T_gap satisfies T_gap=N*T_SMTC_max or T_gap=N*T_CMTC_max, where N is an integer.

[0089] In one example, the auxiliary information is B1, which includes first information and second information, where the first information corresponds to the timing difference being t2 and the second information corresponds to the type of the measurement gap being periodic.

[0090] In one example, the auxiliary information is B2, which includes first information and second information, where the first information corresponds to the timing difference being t2 and the second information corresponds to the type of the measurement gap being aperiodic.

[0091] An embodiment of the present disclosure provides a method for receiving measurement gap configuration information, which is performed by a user equipment 101. The method includes steps S1-1 and S1-2, or steps S1-1' and S1-2'.

[0092] In this method, the auxiliary information includes first information, second information, and third information, where the third information indicates a use of the measurement gap, and the use includes any one of receiving system information or paging information of the target network, measuring cells in the target network, and transmitting data with the target network.

[0093] In one possible example, the third information occupies two bits.

[0094] When the value of the third information is 0, it corresponds to the first use, i.e., receiving system information or paging information of the target network; when the value of the third information is 1, it corresponds to the second use, i.e., measuring cells in the target network; when the value of the third information is 2, data transmission with the target network is performed.

[0095] In this method, if the third information in the auxiliary information corresponds to a different purpose, the measurement gap time length in the first measurement gap configuration information is different.

[0096] In one example, the auxiliary information is C1, which includes first information, second information, and third information, where the first information corresponds to the timing difference being t3-1, the second information corresponds to the measurement gap type being aperiodic, the third information corresponds to the purpose of the measurement gap being cell measurement, and the measurement gap time length is d1.
