The term "and/or" herein is an association relationship describing an associated object, and means that there may be three relationships, for example, a display panel and/or a backlight, which may mean: there are three cases of a display panel alone, a display panel and a backlight at the same time, and a backlight alone. The symbol "/" herein denotes a relationship in which the associated object is or, for example, input/output denotes input or output.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

The following explains some concepts and/or terms involved in the cell measurement method, device and system provided by the embodiments of the present invention.

Conditional switching (CHO): in order to avoid the situation that the UE cannot receive the switching command related message of the source node after the channel condition of the source cell is deteriorated, thereby causing the switching failure, a conditional switching process is introduced.

The steps of the conditional switching process are as follows: a source node sends switching request information to one or more target nodes; the target node feeds back switching confirmation information to the source node; a source node sends configuration information of condition switching to UE; the UE evaluates whether other cells except the resident cell of the UE meet the conditions or not so as to select one cell for switching; UE initiates a random access process in the selected cell; UE sends switching completion information to a target node; the source node sends a cancel condition switching command to other target nodes; and other target nodes send a conditional switch cancellation confirmation command to the source node.

The embodiment of the invention provides a cell measurement method, a device and a system, wherein UE (user equipment) can measure at least one candidate cell according to configuration information (used for indicating at least one candidate cell) sent by network equipment. Because the UE can directly measure at least one candidate cell according to the configuration information, namely the UE can timely and accurately measure the switchable cell indicated by the network equipment, the time delay of the switchable cell measurement can be avoided, the time delay of the UE for cell switching can be reduced, and the success rate of the UE for cell switching can be improved.

The cell measurement method, the cell measurement equipment and the cell measurement system provided by the embodiment of the invention can be applied to a communication system. The method can be particularly applied to the process of conditional switching of the UE based on the communication system.

Fig. 1 is a schematic diagram illustrating an architecture of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system may include a UE 01 and a network device 02. Wherein, the UE 01 and the network device 02 can establish connection and communicate.

A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connectivity, or other processing device connected to a wireless modem. A UE may communicate with one or more core network devices via a Radio Access Network (RAN). The UE may be a mobile terminal such as a mobile phone (or "cellular" phone) and a computer having a mobile terminal, or a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device that exchanges speech and/or data with the RAN, such as a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and so on. The UE may also be referred to as a user agent (user agent) or a terminal device, etc.

The network device may be a base station (e.g., a primary base station or a secondary base station). A base station is a device deployed in a RAN for providing wireless communication functions for UEs. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example, in third generation mobile communication (3G) networks, referred to as base stations (NodeB); in an LTE system, referred to as an evolved NodeB (eNB or eNodeB); in fifth generation mobile communication (5G) networks, referred to as a gNB, and so on. As communication technology evolves, the name "base station" may change. It is to be noted that the embodiment of the present invention is only illustrated by using a 5G network as an example, and should not be taken as a scenario limitation of the embodiment of the present invention.

A cell measurement method provided in an embodiment of the present invention is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a cell measurement method, which is applied to a UE. As shown in fig. 2, the cell measurement method may include steps 201 to 203 described below.

Step 201, the network device sends configuration information to the UE.

In this embodiment of the present invention, the configuration information is used to indicate at least one candidate cell, and the configuration information is used for the UE to measure the at least one candidate cell.

In this embodiment of the present invention, the network device may send a handover command to the UE, where the handover command includes configuration information, and the configuration information is used to indicate candidate cells (i.e. at least one candidate cell) for conditional handover.

In the embodiment of the present invention, in the CHO process, the network device may send a handover command to the UE to instruct the UE to perform cell reselection or cell handover.

Optionally, in this embodiment of the present invention, the configuration information may include at least one of the following: reconfiguration information, a cell switching command, mobile control information, a switching trigger condition, measurement configuration, measurement reporting configuration, an identifier of at least one candidate cell and access channel configuration corresponding to the at least one candidate cell.

Optionally, in this embodiment of the present invention, the reconfiguration message may be a Radio Resource Control (RRC) reconfiguration message (RRC connection reconfiguration), for example, the RRC reconfiguration message may include a cell synchronization parameter (reconfiguration with sync); the cell handover command (HO command) may include handover parameters (e.g., cell random access configuration, etc.) for cell handover; the mobility control info may include parameters to be measured (e.g., measurement frequency points); the handover trigger conditions include threshold values of handover triggers (e.g., A3, a5 measurement configuration, etc.); the measurement configuration may include a measurement object (measurement object), a measurement identifier, a measurement quantity configuration (e.g., Reference Signal Receiving Power (RSRP)), and the like; the measurement report configuration may include a measurement report (measurement report); the access channel may be a Random Access Channel (RACH).

Step 202, the UE receives configuration information sent by the network device.

Step 203, the UE measures at least one candidate cell according to the configuration information.

In the embodiment of the present invention, after receiving the configuration information, the UE may perform measurement on at least one candidate cell to evaluate whether the cells are switchable cells, and switch to the cell after determining the switchable cells.

Optionally, in the embodiment of the present invention, as shown in fig. 3 in combination with fig. 2, the step 203 may be specifically implemented by a step 203a described below.

Step 203a, the UE preferentially measures at least one candidate cell according to the configuration information.

In the embodiment of the present invention, after receiving the configuration information, the UE may preferentially perform measurement on the at least one candidate cell, that is, schedule measurement on the at least one candidate cell before performing measurement on other unconditional handover cells (i.e., cells other than the at least one candidate cell and the cell where the UE camps).

Optionally, in the embodiment of the present invention, after the UE performs measurement on at least one candidate cell, the UE may continue to perform measurement on other unconditional handover cells within the handover duration.

In the embodiment of the invention, when the UE receives the configuration information, the UE can preferentially measure at least one candidate cell, namely the switchable candidate cell can be measured in time, so that the time delay of the UE for measuring the switchable cell can be avoided.

Optionally, in the embodiment of the present invention, as shown in fig. 4 in combination with fig. 3, the step 203a may be specifically implemented by the following step 203b and step 203 c.

Step 203b, the UE determines the measurement priority according to the configuration information.

In this embodiment of the present invention, the measurement priority is used to indicate that the priority of the at least one candidate cell is higher than the priorities of other cells, where the other cells are cells other than the at least one candidate cell and the cell where the UE resides.

Step 203c, the UE preferentially measures at least one candidate cell according to the measurement priority.

In the embodiment of the invention, after receiving the configuration information, the UE can be in a conditional switch measurement mode (namely the UE cell to be measured contains a measurement scheduling mode of a conditional switch candidate cell); in the conditional handover measurement mode, at least one candidate cell has a higher measurement priority than a non-candidate cell (i.e., other cell/other non-conditional handover cell) in measurement scheduling, and the UE may preferentially measure the at least one candidate cell.

Optionally, in the embodiment of the present invention, after the UE preferentially measures the at least one candidate cell, the UE may continue to measure other cells within the handover duration.

In the embodiment of the invention, the UE can preferentially measure at least one candidate cell, namely preferentially measure the switchable candidate cell, so that the time delay of the UE for measuring the switchable cell can be avoided.

Optionally, in the embodiment of the present invention, as shown in fig. 5 in combination with fig. 2, the step 203 may be specifically implemented by a step 203d described below.

Step 203d, the UE sequentially measures at least one candidate cell according to the configuration information and the signal strength of the at least one candidate cell.

In the embodiment of the present invention, the UE may rank the at least one candidate cell according to the signal strength of the at least one candidate cell, and sequentially measure the ranked at least one candidate cell.

Optionally, in the embodiment of the present invention, the UE may rank the at least one candidate cell from high to low according to the signal strength of the at least one candidate cell, and sequentially perform measurement from the candidate cell with high signal strength to the candidate cell with low signal strength.

It is to be understood that the UE may sequentially perform measurement on at least one candidate cell according to the measured signal strength of the at least one candidate cell. The UE may preferentially (e.g., at a target time) measure the candidate cell with the stronger signal strength according to the signal strength of at least one candidate cell.

Optionally, in an embodiment of the present invention, the step 203d may be specifically implemented by the following steps 203d1 to 203d 3.

Step 203d1, the UE obtains the measured candidate cell of the at least one candidate cell according to the configuration information.

In the embodiment of the present invention, in a case that there are candidate cells (e.g., a part of candidate cells or all candidate cells in the at least one candidate cell) that have been previously measured by the UE in the at least one candidate cell, the UE may determine the measured candidate cells from the at least one candidate cell.

Step 203d2, the UE ranks the measured candidate cells and the unmeasured candidate cells of the at least one candidate cell according to the measured signal strengths of the candidate cells.

In the embodiment of the present invention, the UE may rank the measured candidate cells according to the measured signal strengths of the candidate cells, and then rank the unmeasured candidate cells and the ranked measured candidate cells to rank at least one candidate cell.

Optionally, in this embodiment of the present invention, the UE may rank the measured candidate cells from high to low according to the measured signal strengths of the candidate cells.

Optionally, in this embodiment of the present invention, the order of the unmeasured candidate cells is located after the measured candidate cells; alternatively, the order of the unmeasured candidate cells is prior to the measured candidate cells. The specific method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Step 203d3, the UE sequentially measures the ranked measured candidate cells and unmeasured candidate cells.

Optionally, in the embodiment of the present invention, the UE may sequentially measure the ranked measured candidate cells and the candidate cells that are not measured at the target time, so as to measure at least one candidate cell.

Optionally, in the embodiment of the present invention, the UE may preferentially measure the measured candidate cell, and then measure the unmeasured candidate cell; alternatively, the UE may preferentially measure the candidate cells that are not measured and then measure the measured candidate cells.

Optionally, in the embodiment of the present invention, when the UE measures the measured candidate cells, the UE may sequentially measure from a candidate cell with high signal strength to a candidate cell with low signal strength in the measured candidate cells.

Optionally, in the embodiment of the present invention, after measuring the ranked measured candidate cells and the candidate cells that are not measured, the UE may continue to measure other unconditional handover cells within the handover duration.

Optionally, in this embodiment of the present invention, after measuring the ranked measured candidate cells and the non-measured candidate cells, the UE may rank the at least one measured candidate cell again according to the measured signal strength of the at least one candidate cell (including the measured candidate cell and the non-measured candidate cell), and then sequentially measure the ranked at least one candidate cell.

Optionally, in the embodiment of the present invention, when there is no candidate cell that has been measured by the UE before in the at least one candidate cell, the UE may first measure the at least one candidate cell, then rank the at least one candidate cell according to the measured signal strength of the at least one candidate cell, and then sequentially measure the ranked at least one candidate cell.

In the embodiment of the invention, the UE can measure at least one candidate cell according to the signal strength of at least one candidate cell, namely preferentially measure the candidate cell with stronger signal strength in the switchable candidate cells, so that the delay of the UE in measuring the switchable cells can be avoided, and the success rate of cell switching is improved.

Optionally, in the embodiment of the present invention, as shown in fig. 6 in combination with fig. 2, the step 203 may be specifically implemented by a step 203e described below.

Step 203e, the UE performs multiple measurements on at least one candidate cell within the handover duration according to the configuration information.

It should be noted that the above-mentioned handover duration may be understood as a time range/handover time period/handover time window within which the UE may trigger handover.

Optionally, in this embodiment of the present invention, the switching duration may be predefined or configured by a network device.

Optionally, in the embodiment of the present invention, the UE may adjust the handover duration according to the handover performance.

In the embodiment of the invention, the UE can measure at least one candidate cell for multiple times within the switching duration to obtain multiple measurement results so as to meet the sample requirement of smoothing the multiple measurement results and the trigger time requirement of event measurement.

In the embodiment of the invention, in order to meet the multi-sample measurement requirement of the candidate cell in a limited time length range, the UE can reduce the measurement frequency of the non-candidate cell.

In the embodiment of the invention, the UE can measure at least one candidate cell for multiple times in time within the switching duration, can avoid the time delay of the UE for measuring the switchable cells, and can switch the cells according to the measurement results of the multiple measurements, thereby improving the success rate of cell switching, ensuring that the UE stably resides in a better cell and further improving the success rate of a wireless link.

Optionally, in the embodiment of the present invention, when the network device is configured with the trigger event and the relevant configuration of the candidate cell, the UE may perform cell measurement according to the relevant configuration.

The embodiment of the invention provides a cell measurement method, and UE (user equipment) can measure at least one candidate cell according to configuration information (used for indicating at least one candidate cell) sent by network equipment. Because the UE can directly measure at least one candidate cell according to the configuration information, namely the UE can timely and accurately measure the switchable cell indicated by the network equipment, the time delay of the switchable cell measurement can be avoided, the time delay of the UE for cell switching can be reduced, and the success rate of the UE for cell switching can be improved.

Optionally, in this embodiment of the present invention, the configuration information includes a handover trigger condition. Referring to fig. 2, as shown in fig. 7, after step 203, the cell measurement method provided in the embodiment of the present invention further includes steps 301 and 302 described below.

Step 301, the UE determines a target cell according to at least one measurement result.

In this embodiment of the present invention, each of the at least one measurement result is obtained by measuring a candidate cell, and the target cell is a cell in the at least one candidate cell whose measurement result meets the handover trigger condition.

It can be understood that the UE may determine which candidate cells are cells that satisfy the handover trigger condition, i.e., target cells, according to the measurement result corresponding to each candidate cell.

Step 302, the UE switches from the cell where the UE resides to the target cell.

In the embodiment of the invention, the UE can initiate a random access process in the target cell to carry out cell switching.

Optionally, in the embodiment of the present invention, if the target cell includes multiple cells, the UE may select one cell from the target cell to perform cell handover.

In the embodiment of the invention, the UE can determine the cell meeting the switching triggering condition from at least one candidate cell according to at least one measuring result after at least one candidate cell is measured so as to switch to the cell, so that the UE can be ensured to stably reside in a better cell while the time delay of the measurement of the switchable cell is avoided, and the success rate of cell switching and the success rate of a wireless link of the UE can be improved.
