Method, apparatus, device and storage medium for validating radio resource control message

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for validating a radio resource control message, a terminal device, and a computer-readable storage medium.

Background

In a Long Term Evolution (LTE) protocol, if a User Equipment (UE) receives a Radio Resource Control connection release message (RRCConnectionRelease message) from a base station in a connected state, referring to fig. 1, where a is the UE and B is the base station, after an appointed time arrives, the UE starts to execute a series of actions for releasing Radio Resource Control (RRC) configuration; the appointed time is the effective time of the RRC connection release message. In the LTE protocol, the validation time of the RRC connection release message is typically taken to be the earlier time of arrival of both:

60ms of effective time, namely 60ms after receiving an RRC connection release message;

and secondly, the retransmission feedback response of the bottom layer is received successfully.

Currently, in a New Radio Access Technology (NR) of The fifth Generation mobile communication (5G) system, because The NR system is different from The LTE system in design, there is no relevant research or theory on a mechanism for determining The effective time of The RRC connection release message, and if The effective time of The original RRC connection release message is still adopted, The requirements of The NR system on data transmission speed, delay characteristics, and The like cannot be met.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Considering that there may be various configuration parameters for the UE in the 5G NR system, such as frequency-related configuration, access service-related configuration, and operation mode of the UE, these factors are collectively referred to as UE characteristic information in the present invention. Fig. 2 is a flowchart illustrating a method for validating a radio resource control message according to an embodiment of the present invention, where an execution subject in fig. 2 may be a UE.

S101, receiving a Radio Resource Control (RRC) message;

s102, determining the effective time of the RRC message according to the characteristic information of the user equipment UE;

s103, according to the effective time of the RRC message, executing the behavior indicated by the RRC message.

According to the technical scheme of the embodiment of the invention, after the UE receives the RRC message from the base station side, the effective time of the RRC message can be determined according to the characteristic information of the UE, and the RRC message is executed. In the embodiment of the invention, in the process of determining the effective time of the RRC message, the influence of the characteristic information of the UE is considered, the effective time of the RRC message can be flexibly determined according to the specific working condition of the UE, and the effective time of the RRC message can be determined according to the characteristics of an NR system.

In an optional embodiment of the present invention, the determining the effective time of the RRC message according to the characteristic information of the UE in step S102 includes: and acquiring the effective time corresponding to the characteristic information of the UE based on a preset mapping relation, wherein the mapping relation is the mapping relation between the characteristic information of the UE and the effective time of the RRC message.

The mapping relationship described in the embodiment of the present invention is a mapping relationship from the feature information of the UE to the effective time of the RRC message, and the mapping relationship may be a one-to-one correspondence relationship, a one-to-many or many-to-one correspondence relationship, or a many-to-many correspondence relationship.

Since the embodiment of the present invention presets the mapping relationship related to the feature information of the UE and the effective time of the RRC message, when the feature information of the UE is known, the effective time of the RRC message of the UE can be determined according to the preset mapping relationship.

Besides the determination of the effective time of the RRC message based on the mapping relationship, in other embodiments of the present invention, other alternatives may be adopted, for example, the effective time of the RRC message is obtained through necessary calculation, and the same purpose can be achieved.

The embodiments of the present invention are applicable to all RRC procedures that are triggered by the network side and do not require the UE to respond to the uplink RRC layer, for example, the RRC message may be an RRC connection release message, or may be other RRC messages.

Regarding the UE feature information, the UE feature information according to the embodiment of the present invention may include at least one of the following factors: the method comprises the steps of working frequency points of UE, working frequency bands of the UE, active part bandwidth BWP currently configured by the UE, subcarrier spacing SCS currently configured by the UE, minimum subcarrier spacing SCS configurable by the UE, maximum subcarrier spacing SCS configurable by the UE, service types of the UE, access types of the UE, the UE in an energy-saving mode and the UE in a non-energy-saving mode. The factors of the characteristic information of these UEs are described in detail below, respectively.

The working frequency point of the UE is the central frequency point of the frequency range where the UE is located or the number of the central frequency point aiming at the frequency range. For example, in some embodiments of the present invention, a frequency range may be divided into a frequency range smaller than 6GHz and a frequency range larger than 6GHz, and then a center frequency point of the frequency range smaller than 6GHz and a center frequency point of the frequency range larger than 6GHz are respectively used as two working frequency points; in another embodiment, the central frequency point in the frequency range smaller than 6GHz and the central frequency point in the frequency range larger than 6GHz may be respectively numbered, for example, the central frequency point in the frequency range smaller than 6GHz is numbered as 1, the central frequency point in the frequency range larger than 6GHz is numbered as 2, and two working frequency points numbered as 1 and 2 are obtained.

In an optional embodiment of the present invention, the frequency range may be further divided, for example, the frequency range smaller than 6GHz may be further divided into a frequency range smaller than 1GHz and a frequency range from 1GHz to 6GHz, and then the central frequency points in the frequency range smaller than 1GHz and the frequency range from 1GHz to 6GHz may be taken as working frequency points, or the central frequency points in the frequency range smaller than 1GHz and the frequency range from 1GHz to 6GHz are respectively numbered as 3 and 4; by analogy, the frequency range larger than 6GHz can be further subdivided, and the central frequency point is taken as the working frequency point, and the central frequency point can also be numbered and taken as the working frequency point. The invention has no special requirement on the numbering, and can represent different working frequency points, for example, Roman numbers can be adopted for numbering, and Arabic numbers are preferably adopted for numbering.

Table 1 schematically shows a mapping relationship between operating frequency points of a plurality of UEs and effective time of an RRC message in the embodiment of the present invention, and table 1 uses the number of a center frequency point of a frequency range where the UE is located as the operating frequency point. For convenience of viewing, the frequency ranges corresponding to the working frequency points are also listed in table 1. Referring to table 1, wherein N1 through N4 in the third column represent the values of the effective time of the RRC message. Each of N1 to N4 may represent one numerical value or a plurality of numerical values; two or more of N1 to N4 may be the same as each other, and two or more of N1 to N4 may also be different from each other. In the embodiment of the present invention, generally, the relationship between the effective time of the RRC message and the working frequency point is negative, that is, the larger the central frequency point represented by the working frequency point is, the shorter the effective time is.

TABLE 1

Frequency range	Working frequency point	Time of validity of RRC message
			Less than 1GHz	1	N1
1GHz to 6GHz	2	N2
			6GHz	3	N3
Greater than 6GHz	4	N4

It should be noted that all the parameters or parameter ranges in table 1 are only exemplary, and in practical applications, different parameters or parameter ranges may be set according to specific situations and requirements of the system, and an appropriate value may be set for each of N1 to N4 as the effective time of the RRC message; and other working frequency points can be added, and a specific value of the effective time of the RRC message can be set according to the requirement.

Here, since the present invention aims to provide a mechanism for determining the effective time of the RRC message in the NR system, but does not aim to determine the specific value of the effective time of the RRC message, the working frequency points and the values of the effective time of the RRC message represented by N1 to N4 are given in table 1 by way of example, and the solution of the embodiment of the present invention is not unclear or cannot be implemented.

It can be seen that, when the working frequency point of the target UE is known, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the working frequency point of the target UE is 2, the effective time of the RRC message of the target UE should be N2.

TABLE 2

In an embodiment of the present invention, the mapping relationship between the operating frequency point of the target UE and the effective time of the RRC message is shown in table 2. According to table 2, when the working frequency point of the target UE is 3.5GHz, the effective time of the RRC message of the target UE should be 60 ms.

Regarding the operating frequency Band, in the art, for a certain frequency range, for example, for a frequency range smaller than 1GHz, the frequency range smaller than 1GHz can be distinguished by means of a Band number (Band number), so that the frequency range is divided into several operating frequency bands.

TABLE 3

Frequency Band number (Band number)	UL	DL
			n5	824 to 849MHz	869 to 894MHz
n8	880 to 915MHz	925 to 960MHz
			n20	832 to 862MHz	791 to 821MHz
n28	703 to 48MHz	758 to 803MHz
			n71	663 to 698MHz	617 to 652MHz

Table 3 schematically shows the correspondence between the number of the frequency bands and the operating frequency band of the UE in the embodiment of the present invention. The frequency band numbers include n5, n8, n20, n28 and n71, and each frequency band number corresponds to an Uplink (UL) frequency band and a Downlink (DL) frequency band. Taking the frequency band number n5 as an example, it corresponds to that the uplink operating frequency band for the UE to send signals to the base station is 824 to 849MHz, and the downlink operating frequency band for the base station to send signals to the UE is 869 to 894 MHz.

TABLE 4

Frequency Band number (Band number)	Time of validity of RRC message
		n5	M1
n8	M2
		n20	M3
n28	M4
		n71	M5

Table 4 schematically shows the correspondence between the multiple operating bands (indicated by the band numbers) and the time of validity of the RRC message. Wherein M1 through M5 in the second column represent the values of the effective time of the RRC message. Each of M1 to M5 may represent one numerical value or a plurality of numerical values; two or more of M1-M5 may be the same as each other, and two or more of M1-M5 may also be different from each other. In the embodiment of the present invention, generally, the relationship between the effective time of the RRC message and the working frequency band is negative, that is, the larger the central frequency point represented by the working frequency band is, the shorter the effective time is.

It should be noted that all the parameters or parameter ranges in table 4 are only exemplary, and in practical applications, different parameters or parameter ranges may be set according to specific situations and requirements of the system, and an appropriate value may be set for each of M1 to M5 as the effective time of the RRC message; other working frequency bands can be added, and a specific value of the effective time of the RRC message can be set according to requirements.

It can be seen that, when the working frequency band of the target UE is obtained, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the operating frequency band of the target UE is n5, the effective time of the RRC message of the target UE should be M1.

In an optional embodiment, the influence of multiple factors on the system may be considered, and the working frequency point and the working frequency band of the UE are combined to determine the effective time of the RRC message. For example, when knowing that the working frequency point of the target UE is 1, it can be known from table 1 that the corresponding frequency range is less than 1GHz, and further knowing that the working frequency band of the UE is n8, it can be determined from table 4 that the effective time of the RRC message of the target UE is M2.

Regarding the BWP, in the NR technique of the 5G system, the UE may use a Bandwidth adaptive change (Bandwidth Adaptation) technique to dynamically change the Bandwidth, so as to achieve the purpose of saving power consumption. The bandwidth adaptive change technology means that the NR system can dynamically change the currently configured partial Bandwidth (BWP) of the UE according to actual needs (e.g., the traffic size of the UE). For example, fig. 3 schematically shows a schematic diagram of band z (band z) divided into BWP1, BWP2 and BWP3 in the NR system. When the current traffic of the UE is small, the UE operates in a low bandwidth (e.g., BWP1), when the current traffic of the UE is large, the UE may switch to a high bandwidth (e.g., BWP2) to operate, and so on, that is, only the basic communication requirement is satisfied, so that the power consumption may be saved, and the UE may flexibly adapt to various traffic requirements.

Specifically, the currently configured BWP of the UE is active BWP, and the rest is inactive BWP. Different BWPs have different frequency points and different bandwidths, and the corresponding other configurations may also be different, for example: one or more of Sub Carrier Spacing (SCS), Cyclic Prefix (CP) type, and Synchronization Signal Block (SSB) period are different to accommodate different services.

In some embodiments of the invention, different active BWPs may be configured for different UEs; in other embodiments of the present invention, different active BWPs may also be configured for different conditions of the same UE. The different working conditions described herein mean that the active BWP allocated to the UE by the system is different due to different traffic of the UE in different time periods.

TABLE 5

Activating BWP	Time of validity of RRC message
		BWP1	K1
BWP2	K2
		BWP3	K3

Table 5 schematically shows the correspondence between the effective times of different active BWPs and RRC messages in the embodiment of the present invention. Wherein K1 through K3 in the second column represent the values of the effective time of the RRC message. Each of K1 to K3 may represent one numerical value or a plurality of numerical values; two or more of K1 to K3 may be the same as each other, and two or more of K1 to K3 may also be different from each other. In the embodiment of the present invention, generally, the relationship between the effective time of the RRC message and the BWP activation is negative correlation, that is, the larger the central frequency point corresponding to the BWP activation is, the shorter the effective time is.

It should be noted that all the parameters or parameter ranges in table 5 are only exemplary, and in practical applications, different parameters or parameter ranges may be set according to specific situations and requirements of the system, and an appropriate value may be set for each of K1 to K3 as the effective time of the RRC message; other active BWPs may also be added and the appropriate specific value of the validation time of the RRC message set as required.

It can be seen that, when learning the BWP activation of the target UE, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the active BWP of the target UE is BWP3, the effective time of the RRC message of the target UE should be K3.

In an optional embodiment, the effect of multiple factors on the system may be further considered, and one or more of the operating frequency point and the operating frequency band of the UE are combined with BWP activation to determine the effective time of the RRC message. For example, after the working frequency point and the working frequency band of the UE are known, when the active BWP of the target UE is known to be BWP1, the effective time of the RRC message of the target UE may be determined to be K1 through table 5.

With respect to the subcarrier spacing SCS, in the LTE technique, the subcarrier spacing SCS is a fixed value (15 kHz), and in the NR technique, the subcarrier spacing SCS is flexibly expandable. Specifically, the subcarrier spacing SCS in the NR technique may be taken to be 15kHz, 30kHz, 60kHz, 120kHz, and so on. Since the sub-carrier spacing SCS is inversely proportional to the length of an Orthogonal Frequency Division Multiplexing (OFDM) symbol, that is, the larger the sub-carrier spacing SCS is, the shorter the OFDM symbol is, in the embodiment of the present invention, the effective time of the RRC message of the UE may be set according to the sub-carrier spacing SCS, and the effective time of the RRC message may be shortened to some extent under a suitable condition.

Table 6 schematically shows the correspondence between the SCS intervals of several subcarriers and the time of validity of RRC message in the embodiment of the present invention. Wherein S1 through S4 in the second column represent the values of the effective time of the RRC message. Each of S1 to S4 may represent one numerical value or a plurality of numerical values; two or more of S1 to S4 may be the same as each other, and two or more of S1 to S4 may be the same as each other. In the embodiment of the present invention, generally, the effective time of the RRC message is inversely related to the subcarrier spacing SCS, i.e. the larger the subcarrier spacing SCS, the shorter the effective time.

TABLE 6

Subcarrier spacing SCS	Time of validity of RRC message
		15kHz	S1
30kHz	S2
		60kHz	S3
120kHz	S4

It should be noted that all the parameters or parameter ranges in table 6 are only exemplary, and in practical applications, different parameters or parameter ranges may be set according to the specific situation and requirement of the system, and an appropriate value is set for each of S1 to S4 as the effective time of the RRC message; other subcarrier intervals SCS can be added, and the effective time of the RRC message can be set to be a specific value according to requirements.

It can be seen that, when the subcarrier spacing SCS of the target UE is known, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the subcarrier spacing SCS of the target UE is 30kHz, the effective time of the RRC message of the target UE should be taken as S2.

In an optional embodiment, the system may be further influenced by a plurality of factors, and one or more of the operating frequency point, the operating frequency band, and the activation BWP of the UE are combined with the subcarrier spacing SCS to determine the effective time of the RRC message. In one embodiment of the present invention, considering the combination of the active BWP and the subcarrier spacing SCS of the target UE and the mapping of the effective time of the RRC message, as shown in table 7, when the active BWP of the target UE is BWP1 and the subcarrier spacing SCS is 15kHz, the effective time of the RRC message of the target UE is 1 s; when the active BWP of the target UE is BWP3 and the subcarrier spacing SCS is 30kHz, the effective time of the RRC message of the target UE is 60 ms; when the active BWP of the target UE is BWP1 and BWP2 and the subcarrier spacing SCS is 15kHz and 60kHz, the effective time of the RRC message of the target UE is 300 ms. Then, according to table 7, when the UE operates at BWP1 for downlink reception and the subcarrier spacing SCS is 15kHz, the effective time of the corresponding RRC message should be taken to be 1 s.

TABLE 7

Activating BWP and subcarrier spacing SCS	Time of validity of RRC message
		BWP1、15kHz	1s
BWP3、30kHz	60ms
		BWP1、BWP2、15kHz、60kHz	300ms

In addition, the embodiment of the present invention may also determine the effective time of the RRC message according to the UE configurable minimum subcarrier spacing SCS, which may be, for example, the minimum value of all SCS values in the first column of table 6. In practical application scenarios, the minimum subcarrier spacing SCS may be any one of, for example, 15kHz, 30kHz, 60kHz, and 120kHz, and may be a larger value or a smaller value under different configuration conditions. When the UE-configurable minimum subcarrier spacing SCS is known, the effective time of the RRC message corresponding thereto may be determined according to a preset mapping relationship, for example, table 6.

Similarly, the embodiment of the invention can also determine the effective time of the RRC message according to the maximum subcarrier spacing SCS configurable by the UE. Where the UE-configurable maximum subcarrier spacing, SCS, may be, for example, the maximum of all SCS values in the first column of table 6. In practical application scenarios, the maximum subcarrier spacing SCS may be any one of, for example, 15kHz, 30kHz, 60kHz, and 120kHz, and may be larger or smaller, under different configuration conditions. When the maximum subcarrier spacing SCS configurable by the UE is known, the effective time of the RRC message corresponding thereto may be determined according to a preset mapping relationship, for example, table 6.

Regarding the traffic type of the UE, in the NR technique, standardized traffic types (Service types) include the following three types: enhanced Mobile Broadband (eMBB), high-reliability Low latency Communication (URLLC), and enhanced Machine Type Communication (mtc). The eMBB service is generally broadband transmission and needs to provide higher throughput, the URLLC service has higher requirements on reliability and time delay, and the mtc service requires large connection, wide coverage, and low power consumption.

The service type of the UE in the embodiment of the invention refers to one of eMBB service, URLL service and eMTC service. Table 8 schematically shows the correspondence between three service types and the effective time of the RRC message in the embodiment of the present invention. Wherein W1 through W3 in the second column represent the values of the effective time of the RRC message. Each of W1 to W3 may represent one numerical value or a plurality of numerical values; two or more of W1 to W3 may be the same as each other, and two or more of W1 to W3 may also be different from each other.

TABLE 8

Service type of UE	Time of validity of RRC message
		eMBB	W1
URLLC	W2
		eMTC	W3

It should be noted that all the parameters or parameter ranges in table 8 are only exemplary, and in practical applications, different parameters or parameter ranges may be set according to specific situations and requirements of the system, and an appropriate value may be set for each of W1 to W3 as the effective time of the RRC message; other service types can be added, and the effective time of the RRC message can be set to be a specific value according to requirements.

It can be seen that, when the service type of the target UE is known, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the service type of the target UE is eMTC, the effective time of the RRC message of the target UE should be W3.

In an optional embodiment, the system may be further influenced by a plurality of factors, and one or more of the operating frequency point, the operating frequency band, the activation BWP, the subcarrier spacing SCS of the UE may be combined with the service type of the UE to determine the effective time of the RRC message. In a specific embodiment of the present invention, referring to table 9, the effective time of the RRC message corresponding to the eMBB service is 60ms, the effective time of the RRC message corresponding to the URLLC service is 3ms, and the effective time of the RRC message corresponding to the eMTC service is 1s or 10 s; when the service type of the UE is eMTC, the effective time of the corresponding selectable RRC message is 1s or 10s, and for the two candidate values, the UE may select (for example, randomly select) the effective time of the RRC message with 1s or 10s as the final effective time of the RRC message, or may also select the effective time by combining other factors in the embodiment of the present invention (which will be specifically described below).

TABLE 9

Service type of UE	Time of validity of RRC message
		eMBB	60ms
URLLC	3ms
		eMTC	1s、10s

Regarding the Access type of the UE, in the NR technology, a standardized Access Category (AC) value range is 0 to 63. The access AC of the UE according to the embodiment of the present invention refers to a value or a range of values from 0 to 63.

In the 5G NR system, since AC 1 generally corresponds to a class of terminal delay tolerant services, it should correspond to a relatively large effective value, and for other ACs (AC 0,2, 3.., 63, i.e., AC 0 and AC equal to any one of values 2 to 63), it should correspond to a relatively small effective value. Table 10 schematically shows the correspondence between the access AC of the UE and the effective time of the RRC message in the embodiment of the present invention. The access AC of the UE in the first column is divided into two parts, i.e., AC 1 and AC 0,2, 3.., 63, and Q1 and Q2 in the second column represent the effective time value of the RRC message. Each of Q1 and Q2 may represent one numerical value or a plurality of numerical values; q1 and Q2 may be the same as or different from each other.

It should be noted that all the parameters or parameter ranges in table 10 are only illustrative, and in practical applications, different parameters or parameter ranges may be set according to the specific situation and requirement of the system, and an appropriate value is set for each of Q1 and Q2 as the effective time of the RRC message; the AC may also be repartitioned and the appropriate specific value of the validation time of the RRC message set as required.

Watch 10

Access type AC for UE	Time of validity of RRC message
		AC＝1	Q1
AC＝0，2，3，...，63	Q2

It can be seen that, when the access AC of the target UE is known, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the access AC of the target UE is 1, the effective time of the RRC message of the target UE should be taken as Q1.

In an optional embodiment, the system may be further influenced by a plurality of factors, and one or more of the operating frequency point of the UE, the operating frequency band, the BWP activation, the subcarrier spacing SCS, the service type of the UE may be combined with the access AC of the UE to determine the effective time of the RRC message.

TABLE 11

Access type AC for UE	Time of validity of RRC message
		AC＝1	10s
AC＝0，2，3，...，63	3ms、60ms、1s

In an embodiment of the present invention, referring to table 11, when AC is 1, the corresponding RRC message has an effective time of 10s, and when AC is 0,2, 3. When the AC of the UE is 0,2, 3.., 63, the validation time corresponding to the optional RRC message is 3ms, 60ms, or 1 s; further, for the three candidate values, the UE may select (e.g., randomly select) the effective time of the final RRC message with 3ms, 60ms, or 1s, or may select the three candidate values in combination with other factors in the embodiment of the present invention, for example, when the AC is 2 and the RRC is eMTC service, the corresponding effective time of the RRC takes 1 s.

Regarding whether the UE operates in the energy Saving Mode, according to the embodiment of the present invention, whether the UE operates in the energy Saving Mode (UE Power Saving Mode) may also be considered in relation to the mapping relationship between the effective time of the RRC message, that is, the effective time of the RRC message is determined according to whether the UE operates in the energy Saving Mode. Table 12 schematically shows the correspondence between the operation mode of the UE and the effective time of the RRC message in the embodiment of the present invention. Wherein the operation modes of the UEs in the first column are divided into two types, i.e., power saving mode and non-power saving mode, and R1 and R2 in the second column represent the values of the effective time of the RRC message. Each of R1 and R2 may represent one numerical value or a plurality of numerical values; r1 and R2 may be the same as or different from each other. In the embodiment of the invention, the effective time of the RRC message corresponding to the UE working in the energy-saving mode is shorter than the effective time of the RRC message corresponding to the UE working in the non-energy-saving mode.

It should be noted that all the parameters or parameter ranges in table 12 are only illustrative, and in practical applications, different parameters or parameter ranges may be set according to the specific situation and requirement of the system, and an appropriate value is set for each of R1 and R2 as the effective time of the RRC message; other working modes can be added, and the specific value of the effective time of the RRC message can be set according to the requirement.

TABLE 12

Operating mode of UE	Time of validity of RRC message
		Energy saving mode	R1
Non power saving mode	R2

It can be seen that, when the working mode of the target UE is known, the effective time of the RRC message corresponding to the target UE can be obtained according to the mapping relationship, that is, the effective time of the RRC message of the target UE is determined. For example, when the target UE operates in the energy saving mode, the effective time of the RRC message of the target UE should be taken as R1.

Watch 13

Operating mode of UE	Time of validity of RRC message
		Energy saving mode	60s
Non power saving mode	1s

In an embodiment of the present invention, referring to table 13, when the UE operates in the energy saving mode, the effective time of the corresponding RRC message is 60ms, and when the UE operates in the non-energy saving mode, the effective time of the corresponding RRC message is 1 s.

In an optional embodiment, the system may be further influenced by a plurality of factors, and one or more of the operating frequency point of the UE, the operating frequency band, the BWP activation, the subcarrier spacing SCS, the service type of the UE, and the access AC of the UE may be combined with the operating mode of the UE to determine the effective time of the RRC message. For example, two factors, i.e., the service type of the UE and the operating mode of the UE, are combined, and for the third row of eMTC services in table 9, when the service type of the UE is eMTC, the effective time of the corresponding optional RRC message is 1s or 10s, at this time, it may be determined whether the UE operates in the energy saving mode, if the UE operates in the power saving mode, 1s is selected, and if the UE does not operate in the power saving mode, 10s is selected.

The characteristic information of the UE and the mapping relationship between the characteristic information and the effective time of the RRC message according to the present invention are described in detail in the above through a plurality of embodiments. The method of the embodiment of the invention can flexibly determine the effective time of the RRC message according to different influences of BWP, sub-carrier interval SCS, UE service and the like. For example, for the RRC connection release procedure, when the active BWP of the UE uses a larger SCS, the time for RRC connection release of the UE may be shortened, since different sub-carrier spacing SCS are introduced, the effective time of the RRC message may vary according to the variation of the SCS, the OFDM symbol is short when the sub-carrier spacing SCS is larger, and the time for RRC connection release of the UE may be shortened, thereby saving the power consumption of the UE. In practical application, the above operation can be realized by protocol convention, and can also be realized through network pre-configuration or network configuration.

In an optional embodiment of the present invention, after the validation time of the RRC message is determined, the action indicated by the RRC message is performed according to the validation time of the RRC message, and if the RRC message does not require the underlying retransmission feedback, the action indicated by the RRC message is performed when the validation time of the RRC message arrives. Here, the bottom layer is a physical layer and/or a Radio Link Control (RLC) layer.

In some embodiments of the present invention, after the validation time of the RRC message is determined, it may be determined whether the RRC message from the base station requires retransmission feedback of the bottom layer, and a time point for starting to perform an action indicated by the RRC message is determined according to whether the RRC message requires retransmission feedback of the bottom layer. Specifically, it may be determined whether a subcarrier interval currently configured by the UE is a preset subcarrier interval, and if so, it is determined that retransmission feedback of the bottom layer is not needed, where the preset subcarrier interval is a subcarrier interval greater than a preset frequency; whether the UE works in the energy-saving mode can also be judged, and if so, the retransmission feedback of the bottom layer is determined not to be needed.

In some embodiments of the present invention, the RRC message has a bottom layer retransmission feedback, and the UE starts to perform the action indicated by the RRC message when the UE receives the RRC message until the effective time of the RRC message is reached or the bottom layer retransmission feedback response is successfully received. In other embodiments of the present invention, the RRC message has no bottom layer retransmission feedback, for example, if the UE operates at a larger subcarrier interval (120kHz), the UE does not perform the bottom layer retransmission feedback, and if the UE operates in the energy saving mode, the UE does not perform the bottom layer retransmission feedback, and after receiving the RRC message, the UE starts to perform the action indicated by the RRC message until the effective time of the RRC message arrives. And if the RRC message is the RRC connection release message, the behavior indicated by the execution RRC message is the behavior indicated by the execution RRC connection release message.

The method provided by the invention can be used for determining the effective time of the RRC message based on the characteristics of the NR system.

The effective time determining module 200 is further configured to obtain an effective time corresponding to the feature information of the UE based on a preset mapping relationship, where the mapping relationship is a mapping relationship between the feature information of the UE and the effective time of the RRC message.

When the UE operates in the energy saving mode, the effective time determining module 200 takes a first preset time as an effective time of the RRC message; when the UE operates in the non-energy-saving mode, the effective time determination module 200 takes a second preset time as the effective time of the RRC message. Wherein the first preset time is less than the second preset time.

if the first retransmission feedback processing module 400 or the second retransmission feedback processing module 500 determines that the RRC message does not require bottom layer retransmission feedback, the message execution module 300 executes the behavior indicated by the RRC message when the effective time of the RRC message is reached.
