The present disclosure relates to the field of communication application technology, in particular to a non-connection state measurement method, user equipment (UE), and a base station.
In carrier aggregation (CA), UE uses spectrum resources of a plurality of serving cells simultaneously to perform data transmission, thereby improving a throughput of data reception and transmission of the UE.
A serving cell of UE is configured by a network. The network usually selects, based on measurement results of neighboring cells reported by the UE, a cell with signal quality satisfying a specific condition, and configures the cell as the serving cell of the UE. Measurement parameters (for example, a measurement frequency, and a measurement quantity (a reference signal received power (RSRP) and/or a reference signal received quality (RSRQ)) for measurement of a neighboring cell and a reporting configuration (a report triggering condition, a measurement quantity to be reported or the like) of the UE are configured by the network. Activation of security mode is required before a measurement can be configured and reported. Referring to
In a first aspect, the present disclosure provides in some embodiments a non-connection state measurement method, applied to UE, including:
acquiring measurement configuration information from a message broadcasted by a network or a radio resource control (RRC) dedicated message, wherein the measurement configuration information from the RRC dedicated message comprises one or more frequencies and a valid time of the measurement configuration information; the measurement configuration information from the message broadcasted by the network comprises one or more frequencies;
when the measurement configuration information is acquired from the RRC dedicated message,
if the measurement configuration information from the RRC dedicated message is invalid, stopping measurement or when it is detected that the message broadcasted by the network carries the measurement configuration information, performing the measurement according to the measurement configuration information carried in the message broadcasted by the network;
if the measurement configuration information from the RRC dedicated message is valid, starting to perform the measurement according to the measurement configuration information from the RRC dedicated message; and
reporting, by the UE after the UE enters a connected state from a non-connection state, a measurement result obtained from the measurement.
In a second aspect, the present disclosure further provides in some embodiments UE, including: a storage, a processor, and a computer program stored in the storage and configured to be executed by the processor, where the processor is configured to execute the computer program to implement the steps in the foregoing non-connection state measurement method applied to the UE.

To describe the technical solutions in the embodiments of the present disclosure more clearly, the accompanying drawings required for describing the embodiments of the present disclosure are briefly described hereinafter. Apparently, the drawings accompanying the following descriptions show only some embodiments of the present disclosure, and a person of ordinary skill in the art may still derive other drawings from these accompanying drawings without creative efforts.
The technical solutions in the embodiments of the present disclosure are clearly and thoroughly described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are merely some embodiments of the present disclosure, but are not all the embodiments. Based on the embodiments of the present disclosure, all other embodiments derived by a person of ordinary skill in the art without creative efforts shall fall within the scope of the present disclosure. The expression “and/or” used in the claims and the specification represents at least one of the connected objects.
Step 201: Acquiring, by the UE, measurement configuration information, where the measurement configuration information includes one or more frequencies.
The measurement configuration information may further include a measurement quantity to be measured, where the measurement quantity to be measured includes at least one of an RSRP or an RSRQ.
The measurement configuration information may further include report configuration information.
The report configuration information includes target measurement information to be reported and a reporting condition. The reporting condition includes a signal quality threshold for reporting and a time to trigger (TTT). The target measurement information may specifically include at least one of an RSRP or an RSRQ.
The signal quality threshold for reporting refers to that reporting is triggered only when the signal quality is greater than the threshold. The TTT refers to that reporting is triggered only when the signal quality has been greater than the threshold for a particular duration.
Step 202: Starting, by the UE in a non-connection state, to perform measurements in the one or more frequencies according to the measurement configuration information.
Specifically, one or more frequencies are selected from N frequencies for signal quality measurement. The UE in the non-connection state includes the UE in an idle state or the UE in an inactive state. N is a positive integer.
Step 202 may specifically include: selecting a first preset quantity of frequencies from frequencies included in the measurement configuration information to perform measurement; or randomly selecting a preset quantity of frequencies from frequencies included in the measurement configuration information to perform measurement.
For example, first X frequencies are selected from N frequencies to perform measurement or X frequencies are randomly selected from the N frequencies to perform measurement, where N is a positive integer, and X is a positive integer less than or equal to N.
Preferably, when it is detected that a measurement trigger condition is satisfied, the UE in the non-connection state starts to perform the measurements according to the measurement configuration information.
The measurement trigger condition includes:
a paging message for the UE is received; or
a predetermined moment before a paging occasion when a paging message is received is reached, a time interval between the predetermined moment and the paging occasion is determined in a protocol or configured by a base station; or
a start signal for non-connection state measurement is received; or
the UE has uplink data to transmit; or
the measurement configuration information is received.
In addition, the UE stops the measurements when a radio resource control (RRC) connection complete message or an RRC connection resume complete message is transmitted, or a measurement result is reported; or
the UE stops the measurements after an RRC connection complete message or an RRC connection resume complete message has been transmitted or a measurement result has been reported; or
the UE stops the measurements if the measurements are started at a predetermined moment before a paging occasion when a paging message is received, and the UE does not detect that the UE is paged at the paging occasion, where a time interval between the predetermined moment and the paging occasion is determined in a protocol or configured by a base station; or
the UE stops the measurements after an RRC connection setup fails; or
the UE stops the measurements after the UE receives a connected-state measurement configuration; or
the UE stops the measurements if a preset time duration has elapsed since the UE started the measurement, where the preset time duration is specified in a protocol or configured by a base station or is equal to a valid time of the measurement configuration information.
Step 203: Reporting, by the UE after the UE enters a connected state from the non-connection state, a measurement result obtained from the measurements.
In the non-connection state measurement method in embodiments of the present disclosure, UE in a non-connection state starts to perform measurements in frequencies according to measurement configuration information indicated by a base station, and after entering a connected state from the non-connection state, the UE reports a measurement result obtained from the measurements. According to some embodiments of the present disclosure, UE starts to perform measurements in frequencies while the UE is in a non-connection state, and therefore after entering a connected state, the UE can rapidly report a measurement result, so that a base station can configure a secondary cell in advance according to the measurement result, thereby reducing the latency from when the UE enters the connected state to when high-speed data transmission may start.
As an optional implementation, the step 201 of acquiring measurement configuration information may include: acquiring the measurement configuration information from a message broadcasted by a network.
As another optional implementation, the step 201 of acquiring measurement configuration information includes: acquiring the measurement configuration information from an RRC dedicated message.
The RRC dedicated message may be specifically an RRC connection release message used by a network to release an RRC connection of the UE so that the UE may enter the non-connection state.
If the measurement configuration information is acquired from the RRC dedicated message, the step 202 of starting, by the UE in a non-connection state, to perform measurements in the one or more frequencies according to the measurement configuration information includes:
detecting whether the measurement configuration information from the RRC dedicated message is valid;
if the measurement configuration information from the RRC dedicated message is invalid, when it is detected that the message broadcasted by the network carries the measurement configuration information, starting to perform the measurements according to the measurement configuration information carried in the message broadcasted by the network; and
if the measurement configuration information from the RRC dedicated message is valid, starting to perform the measurements according to the measurement configuration information from the RRC dedicated message.
The measurement configuration information further includes a valid time of the measurement configuration information; and the step of starting to perform the measurements according to the measurement configuration information carried in the message broadcasted by the network includes: when the measurement configuration information from the RRC dedicated message is invalid, if the measurement configuration information carried in the message broadcasted by the network includes a first target frequency the same as a current measurement frequency, preferentially selecting the first target frequency from frequencies included in the measurement configuration information carried in the message broadcasted by the network to perform measurement.
Specifically, a timer is initiated when the UE receives the measurement configuration information indicated by the RRC dedicated message. When a timer expires, it is determined that the measurement configuration information from the RRC dedicated message is invalid.
Herein, when the measurement configuration information from the RRC dedicated message is invalid, the first target frequency is preferentially selected from the N frequencies to perform measurement, thereby ensuring the continuity of measurement.
The step of detecting whether the measurement configuration information from the RRC dedicated message is valid includes: when it is detected that a preset condition is satisfied, determining that the measurement configuration information from the RRC dedicated message is invalid, otherwise, determining that the measurement configuration information from the RRC dedicated message is valid.
The preset condition includes one or more of following conditions:
a timer of the UE expires, where the timer starts timing when the UE receives the RRC dedicated message; or
the UE changes an attached cell; or
the UE enters the connected state; or
the UE performs a public land mobile network (PLMN) reselection.
Further, step 202 of starting, by the UE in a non-connection state, to perform measurements in the one or more frequencies according to the measurement configuration information includes: when the UE moves from a first cell to a second cell, if frequencies acquired from the second cell include a second target frequency the same as a current measurement frequency, preferentially selecting the second target frequency from the frequencies acquired from the second cell to perform measurement.
Herein, when the UE moves from the first cell to the second cell, the second target frequency is preferentially selected from the N measurement frequencies acquired from the second cell to perform measurement, thereby ensuring the continuity of measurement.
Further, the step 203 of reporting, by the UE after the UE enters the connected state from the non-connection state, a measurement result obtained from the measurements includes: notifying, by the UE after the UE enters the connected state from the non-connection state, a base station that the UE has a measurement result to report; and reporting the measurement result after a measurement result reporting indication is received, wherein the measurement result reporting indication is transmitted by the base station according to the notification.
Further, the step of notifying a base station that the UE has a measurement result to report includes: if the measurement result satisfies the reporting condition in the measurement configuration information, notifying the base station that the UE has a measurement result to report.
Further, the step 203 of reporting, by the UE after the UE enters the connected state from the non-connection state, a measurement result obtained from the measurements includes:
notifying, by the UE after the UE enters the connected state from the non-connection state, a base station that the UE has a measurement result to report;
acquiring a measurement result reporting indication transmitted by the base station according to the notification, where the measurement result reporting indication carries report configuration information, and the report configuration information includes target measurement information to be reported and a reporting condition; and
reporting the measurement result if the measurement result satisfies the reporting condition in the measurement result reporting indication.
An RRC connection setup complete message or an RRC connection resume complete message is used to notify the base station that the UE has a measurement result to report.
In the non-connection state measurement method according to some embodiments of the present disclosure, UE in a non-connection state starts to perform measurements in frequencies according to measurement configuration information indicated by a base station, and after entering a connected state from the non-connection state, the UE reports a measurement result obtained from the measurements. According to some embodiments of the present disclosure, UE starts to perform measurements in frequencies while the UE is in a non-connection state, and therefore after entering a connected state, the UE can rapidly report a measurement result, so that a base station can configure a secondary cell in advance according to the measurement result, thereby reducing the latency from when the UE enters the connected state to when high-speed data transmission may start.
A specific application process of embodiments of the present disclosure is described below.
First Application Process
Step 301: Acquiring measurement configuration information by receiving a message broadcasted by a network, where the measurement configuration information includes N measurement frequencies, a parameter to be measured, and report configuration information.
N is a positive integer.
Step 302: Starting, by UE in a non-connection state, to perform measurements in the frequencies according to the measurement configuration information.
Step 303: In an RRC connection process, notifying, by using an RRC connection setup complete message, a base station that the UE has a measurement result to report.
Specifically, if the UE has performed measurement and there is a measurement result, the UE indicates that the UE has a measurement result to report.
Preferably, if the UE has not performed measurement or there is no measurement result, the UE indicates that the UE has no measurement result to report.
Preferably, if the UE has performed measurement and a measurement result satisfies a reporting condition, the UE indicates that the UE has a measurement result to report.

Step 403: In an RRC connection process, notifying, by using an RRC connection setup complete message, a base station that the UE has a measurement result to report.
Specifically, if the UE has performed measurement and there is a measurement result, the UE indicates that the UE has a measurement result to report.

Third Application Process
Step 501: Acquiring measurement configuration information from an RRC dedicated message, where the measurement configuration information includes N measurement frequencies, a parameter to be measured, report configuration information, and a valid time of the measurement configuration information.
N is a positive integer. The RRC dedicated message may be an RRC connection release message used by a network to release an RRC connection of UE so that the UE may enter a non-connection state.
After receiving the measurement configuration information, UE starts a timer with a duration equal to the valid time, and when the timer expires, the measurement configuration information is invalid; or when it is detected that the UE changes an attached cell, the measurement configuration information is invalid; or when the UE enters a connected state and performs a PLMN reselection, the measurement configuration information is invalid.
Step 502: If the measurement configuration information from the RRC dedicated message is invalid, when it is detected that a message broadcasted by a network carries the measurement configuration information, starting to perform the measurements according to the measurement configuration information carried in the message broadcasted by the network.
