It should be understood that a device having a communication function in a network/system according to an embodiment of the present application may be referred to as a communication device. Taking the communication system shown in fig. 1 as an example, the communication device may include a network device and a terminal device with a communication function, where the network device and the terminal device may be specific devices in the embodiments of the present application, and are not described herein again; the communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

In order to facilitate understanding of the embodiments of the present application, the following description will simply explain the basic flow and basic concept involved in the embodiments of the present application. It should be understood that the following description of the basic flow and the basic concepts are not intended to limit the embodiments of the application.

The main application scenario of 5G is: mobile ultra-wideband (eMBB, enhanced Mobile Broadband), low latency high reliability Communications (URLLC, ultra Reliable Low Latency Communications), large scale machine class Communications (mMTC, massive Machine Type Communications). Wherein eMBB aims at obtaining multimedia content, service and data by users, and the demand of eMBB is very rapid to increase; since eMBB may be deployed in different scenarios, such as indoors, urban, rural, etc., the capability and requirements are also quite different, detailed analysis must be performed in connection with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical features of mMTC include: high connection density, small data volume, delay insensitive traffic, low cost, long service life, etc.

In a 5G network environment, for the purposes of reducing air interface signaling and fast recovery of radio connections, fast recovery of data traffic, a new RRC (radio resource control ) state, namely an rrc_inactive state, is defined. This state is different from the rrc_idle state, rrc_active state, or rrc_connected state, respectively:

rrc_idle state: mobility is UE-based cell selection reselection, paging is initiated by the Core Network (CN) and the paging area is configured by the CN. Accordingly, the base station side does not have a UE Access Stratum (AS) context and does not have an RRC connection.

Rrc_connected state: the UE and the base station side are connected by RRC, and the base station and the UE have UE AS context. The position of the UE acquired by the network side is at the cell level; mobility is network-side controlled. And unicast data may be transmitted between the UE and the base station.

Rrc_inactive state: mobility is cell selection reselection based on UE, there is a connection between CN-NR (New Radio); the UE AS context exists at a base station, paging is triggered by the radio access network (RAN, radio Access Network), the RAN-based paging area is managed by the RAN, and the network side knows that the UE location is based on the RAN paging area level.

Slice (Slicing), i.e. network slice, is intended to provide different network services and quality of service for different traffic and for unused subscribers. Just like our expressway divides passenger lanes, cargo lanes, emergency lanes, and is arranged to travel on different roads according to the requirements of different vehicles. The strong demands of the vertical market for wireless communications are witnessed, and the RAN needs to enhance support for vertical services in order to meet the demands of the vertical industry for latency, mobility, reliability, location accuracy, etc. One way is to provide services with lower latency, more targeting, greater flexibility and higher scalability for multiple services with different requirements based on network slicing. More specifically, the RAN slice (Slicing) may enable the application provider to participate in the design, deployment, and operation of the custom RAN, better supporting the services of the application provider.

The terminal device idle state records and reports logged measurement reports: in order to better understand the performance of a mobile network, a mobile network builder or network operator needs to drive a car along a fixed line to collect a series of measurements reflecting the current network performance, such as the quality/interference of the downlink signal. Based on the collected measurement quantity about the network performance, the network optimization team can then adjust the deployment of the mobile network device, the strength of the signal, and the setting of the antenna angle, so as to improve the performance of the mobile network and the satisfaction of the user. However, the method has the disadvantage that as the scale of the mobile network is enlarged, the drive test becomes more time-consuming and labor-consuming, which is unfavorable for the mobile operator to adjust the network deployment in time and consume great cost.

Based on this, mobile networks introduce a signal acquisition method called Minimization of Drive Tests (MDT), whose core idea is to enable numerous terminal devices to report their signal acquisition in case of acquisition of terminal grants. On the premise that the number of terminal devices is sufficient, the network can quickly and economically acquire the network performance related information in the area, and the mode of collecting the network performance of the terminal devices in some target areas is called management-based MDT (management-based MDT). MDT is also used to assist the network in collecting network performance related data for a particular end device (e.g., the end device user often complains about poor network performance), and this mode of MDT collection is known as signal-based MDT (signed-based MDT). The MDT configuration file is sent to the terminal through a 5G core network control plane network element or a network management (OAM), and after the terminal completes the acquisition and reports to the base station, the base station sends it to an independent MDT data analysis network element (TCE, trace collection entity).

The configuration signaling of the MDT must be transmitted to the terminal by the network while the terminal is in RRC Connected state. When the network is configured with logged (recorded) MDT, the terminal reports the measurement quantity recorded when the network is back to rrc_idle (RRC idle state) to the network when the connected state is restored. The specific flow is shown in fig. 2, and may include: the network device, such as the gNB, sends logged measurement configuration (logged measurement configuration) to the terminal device; the measurement is completed under the condition that the terminal equipment is in an idle state; entering RRC connected mode and sending an indication such that the network knows that the terminal device has a measurement report to upload, e.g. may indicate "logMeasAvailable"; then the network device such as gNB sends request information to the terminal device; the terminal equipment feeds back response information; and the network equipment gNB acquires the MDT record report from the response information and reports the MDT record report to the TCE.

Wherein Logged MDT supports two measurement logging triggering modes, namely periodicity and event triggering. When the trigger pattern is periodic, the terminal records measured radio measurement results (radio measurement result) at intervals. When the trigger mode is event type, the terminal records radio measurement results (radio measurement result) and reports Logged measurement report (recorded measurement report) when the configuration event condition is satisfied

It should be understood that the "indication" mentioned in the embodiments of the present application may be a direct indication, an indirect indication, or an indication having an association relationship. For example, a indicates B, which may mean that a indicates B directly, e.g., B may be obtained by a; it may also indicate that a indicates B indirectly, e.g. a indicates C, B may be obtained by C; it may also be indicated that there is an association between a and B.

In the description of the embodiments of the present application, the term "corresponding" may indicate that there is a direct correspondence or an indirect correspondence between the two, or may indicate that there is an association between the two, or may indicate a relationship between the two and the indicated, configured, etc.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description describes related technologies of the embodiments of the present application, and the following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as alternatives, which all belong to the protection scope of the embodiments of the present application.

Fig. 3 is a schematic flow chart of an information reporting method according to an embodiment of the present application. The method may alternatively be applied to the system shown in fig. 1, but is not limited thereto. The method includes at least some of the following.

S310, under the condition that the terminal equipment enters a connection state, information is sent to a network;

Before executing S310, the solution provided in this embodiment may further include: the terminal equipment receives the record measurement configuration information; the recorded measurement configuration information comprises a trigger condition.

Wherein the recorded measurement configuration information may be denoted logged measurement configuration (recorded measurement configuration). The recording measurement configuration information may be sent by a network device to the terminal device, specifically, the network device carries the recording measurement configuration information in RRC signaling and sends the recording measurement configuration information to the terminal device in a connected state; wherein, the connection state may refer to an RRC connection state. At least the above-mentioned trigger condition may be included in the recorded measurement configuration information. It should also be noted that other content may be included in the record measurement configuration information, such as configuration of the following pilot strength measurement record, configuration record duration, etc., which is not intended to be exhaustive.

The embodiment may further include, before executing the step S310: and generating the cell reselection related information under the condition that the triggering condition is met.

The triggering condition may include: and a proper cell is not found at the frequency point corresponding to the slice with high priority.

Wherein the high priority slices may refer to one or more slices having a higher priority than the slices for which the suitable cell is searched.

The generating the cell reselection related information under the condition that the triggering condition is satisfied may specifically include the following two processing methods, respectively:

The first processing mode is as follows:

The triggering conditions may specifically include: finding a proper cell at a frequency point corresponding to a slice with a target priority, and not finding a proper cell at a frequency point corresponding to other slices with high priorities with priorities higher than the target priority.

This way of processing can be understood as:

The terminal equipment performs cell reselection processing based on the priority of the slice, and searches a proper cell at a frequency point corresponding to the slice with the target priority;

And if the target priority is other priorities except the highest priority, determining that the triggering condition is met, and generating the cell reselection related information.

Specifically, the generating the cell reselection related information may include, in a case where the trigger condition is satisfied:

The terminal equipment searches the cell from the frequency points corresponding to the slices with the highest priority in all the slices;

If no suitable cell is searched in the frequency point corresponding to the slice with the highest priority, selecting the slice with the highest priority from the current rest slices;

Cell searching is carried out on the frequency point corresponding to the slice with the highest priority level until a proper cell is searched on any slice with the highest priority level, and at the moment, the priority level corresponding to the slice searched for the proper cell can be called as target priority level; and determining that the triggering condition is met, and generating the cell reselection related information.

In addition, it may further include: and the terminal equipment performs cell reselection processing based on the priority of the slice, searches a proper cell at a frequency point corresponding to the slice with the highest priority, and does not generate the cell reselection related information.

The generating the cell reselection related information may refer to: the cell reselection related information is generated based at least on related information of a slice in which a suitable cell is searched and related information of a high priority slice in which a suitable cell is not searched.

Further, the cell reselection related information may include at least one of the following:

Slice priority configured by the network device;

the corresponding relation between the frequency points configured by the network equipment and the slices;

the terminal equipment executes the position before cell reselection;

The position of the terminal equipment when the cell reselection is executed;

the terminal equipment performs cell reselection on the high-priority slices and does not find the number of slices of a proper cell;

The terminal equipment performs cell reselection on the high-priority slice and does not find a suitable slice number set of the cell;

The terminal equipment performs cell reselection on the high-priority slice and does not find a slice number of a proper cell;

The terminal equipment performs cell reselection and finds out a proper cell slice number;

And the related information of the cell where the terminal equipment currently resides.

It should be noted that, at least the above cell reselection related information may include: the terminal equipment performs cell reselection on the high-priority slice and does not find a suitable slice number set of the cell; or the terminal device performs cell reselection on the high priority slices and does not find the number of slices of the suitable cell.

On this basis, the cell reselection related information may further include at least one of the following: slice priority configured by the network device; the corresponding relation between the frequency points configured by the network equipment and the slices; the terminal equipment executes the position before cell reselection; the terminal device performs a location at the time of cell reselection.

Wherein the terminal device performs cell reselection on a high priority slice and does not find a suitable cell's slice number set may refer to: and a set of slice numbers of all slices having a higher priority than the slice currently searching for a suitable cell. That is, the terminal device performs cell reselection on the frequency point corresponding to the high priority slice, and does not find a set composed of slice numbers of suitable cells.

For example, slice priority is configured to: { slice#1:5, slice#2:4, slice#3:3}, slice#3 is a slice in which a suitable cell is finally searched, the priority of slice#3 may be the target priority, and other high-priority slices higher than the target priority of slice#3 include slice#1 and slice#2, so the terminal device performs cell reselection on the high-priority slice and does not find a slice number set of the suitable cell (for example, the slice number may be expressed as a slice ID) may include: (slice#1, slice#2).

The terminal device performing cell reselection on the high priority slice and not finding a suitable cell's slice number may refer to: the slice number of all slices having a higher priority than the slice currently searching for a suitable cell. That is, the terminal device performs cell reselection on the frequency point corresponding to the high priority slice, and does not find a suitable slice number of the cell.

In a preferred embodiment of the present processing manner, the cell reselection related information may include: the terminal equipment performs cell reselection on the high-priority slice and does not find a suitable slice number set of the cell; and the cell reselection related information may not be included in the cell reselection related information: the terminal equipment performs cell reselection on the high-priority slice and does not find a slice number of a proper cell; or vice versa. That is, the above-described terminal device performs two kinds of information, namely, a set of slice numbers of a cell that is reselected and that is not found suitable on a high priority slice, and a slice number of a cell that is reselected and that is not found suitable on a high priority slice, only one of the cell reselection-related information being included.

The number of slices in which the terminal device performs cell reselection on the high-priority slice and does not find a suitable cell may specifically be: and before the terminal equipment searches the proper cell, performing cell reselection on the frequency point corresponding to the high-priority slice, and not finding the number of the high-priority slices of the proper cell.

For example, slice priority is configured to: { slice#1:5, slice#2:4, slice#3:3}, slice #3 is a slice in which a suitable cell is finally searched, and since the cell search is performed based on the priority of the slice, a search cycle of 2 cell reselections has been performed before the cell corresponding to slice #3 is searched, and accordingly, the terminal device performs cell reselection on a high priority slice and does not find a suitable cell, the number of slices is 2.

The terminal device performs cell reselection to find a suitable cell slice number, and the specific determination method may be: in the process of cell reselection executed by the terminal equipment, a proper cell is searched on a frequency point corresponding to a slice with a target priority; and taking the slice number of the slice corresponding to the target priority as the slice number for finding the proper cell. The slice number of the slice may specifically be a slice ID.

For example, slice priority is configured to: { slice#1:5, slice#2:4, slice#3:3}, slice#3 is a slice of the finally searched suitable cell, and the terminal device performs cell reselection, and the found slice ID of the suitable cell is "slice#3".

The information about the cell in which the terminal device currently resides may refer to: the terminal device resides in a cell before entering a connected state. The connected state may be referred to as an RRC connected state.

The relevant information of the cell where the cell currently resides may specifically be: the ID (Identity) of the currently camping cell, for example, may be the number of the cell or the index number of the cell, etc., which is not exhaustive here.

The slice priority configured by the network device may specifically be: the network device configures the slice priority configuration of the terminal device in advance, wherein the slice ID and the corresponding priority are contained in the slice priority configuration.

The slice priority configuration may specifically include: an ID of at least one slice and a priority corresponding to each slice of the at least one slice.

The slice priority configuration stored by the terminal device may be configured for a network device. For example, the system information sent by the terminal device through the network device may be obtained, or the terminal device may be obtained through RRC signaling sent by the network device (for example, the terminal device may be obtained through RRC signaling when the terminal device is in an RRC connected state last time).

In the slice priority configuration stored by the terminal equipment, the slice priorities may be the IDs of all slices in the current system and the priorities corresponding to all slices; or just the IDs of one or more of all the slices in the current system and their respective priorities.

For example, there may be a total of 10 slices in the current system, and the slice priority configuration may be that of only the slices supported or corresponding by the terminal device. For example, the slice priority configuration stored by one terminal device includes the priority of slice 1, the priority of slice 2, and the priority of slice 5 in all 10 slices. The network device configures 3 slices for the terminal device in advance, and the slice IDs corresponding to the 3 slices are: slice 01, slice 02 and slice 03, and the priorities corresponding to the 3 slices are configured for the terminal device, for example, the priority of slice 01 is 10, the priority of slice 02 is 8, and the priority of slice 03 is 5. Correspondingly, the cell reselection related information may include IDs of all slices configured by the network device and priorities corresponding to the IDs.

The correspondence between the frequency points and the slices configured by the network device may specifically be: the network device is configured for the terminal device in advance, and the ID of the slice and the corresponding frequency point are contained in the configuration of the corresponding slice of the frequency point.

The configuration of the frequency point corresponding slice may include: the method comprises the steps of at least one slice ID and a frequency point corresponding to each slice in the at least one slice.

The configuration of the corresponding slice of the frequency point stored by the terminal equipment can be configured for network equipment, for example, the configuration can be obtained by the terminal equipment through system information sent by the network equipment; or may be acquired by the terminal device through RRC signaling sent by the network device (for example, may be acquired by RRC signaling when the terminal device is in a connected state last time).

In the configuration of the corresponding slices of the frequency points stored by the terminal equipment, the configuration may be the slice numbers of all slices in the current system and the frequency points corresponding to all slices; or may simply be the slice number of one or more of the total slices in the current system and its respective corresponding frequency bin.

For example, there may be 10 slices in the current system, and the configuration of the slice corresponding to the frequency point may be only the frequency point of the slice supported or corresponding by the terminal device, for example, the configuration of the slice corresponding to the frequency point stored by one terminal device includes the frequency point a of the slice 01, the frequency point B of the slice 02, and the frequency point C of the slice 03 in all 10 slices.

It should be understood that the slice priority configuration and the configuration of the slice corresponding to the frequency point may be the same, for example, the priority corresponding to the slice 01 and the priority corresponding to the slice 02 are included in the slice priority configuration, and the frequency point corresponding to the slice 01 and the frequency point corresponding to the slice 02 may also be included in the configuration of the slice corresponding to the frequency point.

The location before the terminal device performs the cell reselection may specifically refer to a geographic location where the terminal device performs the cell reselection, for example, may be represented by longitude and latitude.

The location of the terminal device when performing cell reselection may specifically refer to a geographic location where the terminal device performs processing of cell reselection, for example, may be represented by longitude and latitude.

The obtaining manner of the geographic location may be that the terminal device itself is measured by a sensor, or may be obtained by another manner, which is not limited in this embodiment.

An exemplary description is made of the above first processing method:

Assume that the slice priority configured by the network device for the terminal is configured to: { slice#1:5, slice#2:4, slice#3:3}, that is, there are 3 slices, and slice IDs are slice#1 (slice#1), slice#2 (slice#2), and slice#3 (slice#3), respectively, where the priority of slice#1 is 5, i.e., the highest priority, the priority of slice#2 is 4, i.e., the medium priority, and the priority of slice#3 is 3, i.e., the lowest priority.

The configuration of the frequency point corresponding slice may include: the frequency point corresponding to each slice ID, for example, the frequency point 1 corresponding to slice#1, the frequency point 2 corresponding to slice#2, and the frequency point 3 corresponding to slice#3.

Correspondingly, the terminal equipment sequentially searches on the frequency points 1 and 2 corresponding to the slice#1 and the slice#2 according to the slice priority configuration, and does not search for a proper cell on the slice#1 and the slice#2; and searching a proper cell on the frequency point 3 corresponding to the slice#3, wherein the priority of the slice#3 is the target priority. Since the terminal does not search for the suitable cell in the other high priority 2 slices (slice #1 and slice # 2) having the higher priority than the target priority before searching for the slice #3 of the suitable cell, it is determined that the trigger condition is satisfied, and the cell reselection related information is generated.

In the above example, the cell reselection related information may include: the terminal device performs cell reselection on the high priority slice and does not find the slice ID set of the appropriate cell, i.e., (slice#1, slice#2).

Further, the cell reselection related information may include: and the terminal equipment executes the slice ID corresponding to the proper cell found by cell reselection.

On this basis, the cell reselection related information may further include at least one of: slice priority { slice#1) configured by network device: 5, slice#2:4, slice#3:3}; correspondence between frequency points configured by the network device and slices (corresponding to frequency point 1 of slice#1, corresponding to frequency point 2 of slice#2, corresponding to frequency point 3 of slice#3); the terminal device performs a location (longitude, latitude) before cell reselection; and the cell ID-1 where the terminal equipment currently resides.

The second processing mode is as follows:

The triggering conditions may specifically include: and starting searching from the frequency point corresponding to the slice with the highest priority in the slices which are not searched currently according to the order of the priorities from high to low, and not finding a proper cell.

The terminal equipment searches the cell from the frequency points corresponding to the current highest priority slice in all slices;

If no suitable cell is searched in the frequency point corresponding to the slice with the highest priority, determining that the triggering condition is met, and generating the cell reselection related information corresponding to the slice with the highest priority;

And continuing to select the slice with the highest current priority from the current rest slices, and searching the cell at the frequency point corresponding to the slice with the highest current priority until a proper cell is searched on the slice with any priority.

That is, in the second processing manner, the cell reselection related information is generated once when no suitable cell is searched for in the frequency point corresponding to the highest priority slice among the slices which are not currently searched, so that the number of the finally obtained cell reselection related information can be one or more.

In addition, the terminal equipment performs cell reselection processing based on the priority of the slice, and does not generate the cell reselection related information under the condition that a frequency point corresponding to the slice with the highest priority searches a proper cell.

The generating the cell reselection related information may refer to: the cell reselection related information is generated based at least on related information of high priority slices for which no suitable cell is searched.

Slice priority configured by the network device;

the terminal equipment executes the position before cell reselection;

The position of the terminal equipment when the cell reselection is executed;

It should be noted that, at least the above cell reselection related information may include:

Or the terminal device performs cell reselection on the high priority slices and does not find the number of slices of the suitable cell.

Further, the cell reselection related information may include: and the terminal equipment performs cell reselection and finds a slice number corresponding to a proper cell.

On this basis, the cell reselection related information may include at least one of the following: slice priority configured by the network device; the corresponding relation between the frequency points configured by the network equipment and the slices; the terminal equipment executes the position before cell reselection; and the related information of the cell where the terminal equipment currently resides.

Wherein, the terminal device performs cell reselection on the high priority slice and does not find a slice number of the suitable cell may refer to: and the terminal equipment performs cell reselection on the frequency point corresponding to the high-priority slice, and does not find the slice number of the proper cell.

In this processing manner, since the terminal device generates the cell reselection related information once every time a suitable cell is not searched, the cell reselection related information may include a slice number of the cell that the terminal device currently performs cell reselection on a high priority slice and does not find a suitable cell, and the slice number may be represented as a slice ID.

For example, slice priority is configured to: { slice#1:5, slice#2:4, slice#3:3}, no suitable cell slice is searched for in slice #1, and cell reselection related information is generated at this time; the cell reselection related information includes: the terminal equipment performs cell reselection on the high-priority slice, and the slice ID of the cell where no suitable cell is found is slice#1;

The slice #2 does not search for a suitable cell, and at this time, the cell reselection related information is generated and includes: the terminal device performs cell reselection on the high priority slice and does not find the slice ID of the appropriate cell as slice #2.

The information about the cell in which the terminal device currently resides may refer to: the terminal device resides in a cell before entering a connected state. The information about the currently camping cell may specifically be an ID (Identity) of the currently camping cell. The connected state may be referred to as an RRC connected state.

The slice priority configured by the network device may specifically be: the ID of the slice and its corresponding priority contained in the slice priority configuration preconfigured by the network device.

The correspondence between the frequency points and the slices configured by the network device may specifically be: the preset frequency point of the network equipment corresponds to the ID of the slice contained in the configuration of the slice and the corresponding frequency point.

The detailed description of the configuration of the slice priority and the configuration of the corresponding slice of the frequency point is the same as the first processing manner, and is not repeated here.

The location before the terminal device performs cell reselection may specifically be: the geographical location where the terminal device is located before performing a cell reselection may be represented by longitude and latitude, for example.

The location of the terminal device when performing cell reselection may specifically be: the geographical location where the terminal device performs the cell reselection process may be represented by, for example, longitude and latitude.

An exemplary description will be made of the above second processing mode:

The configuration of the corresponding slice of the frequency point configured by the network device for the terminal may include the frequency point corresponding to each slice ID, for example, the configuration of the corresponding slice of the frequency point is that the corresponding slice of slice#1 corresponds to frequency point 1, the corresponding slice#2 corresponds to frequency point 2, and the corresponding slice#3 corresponds to frequency point 3.

Correspondingly, the terminal equipment firstly searches on the frequency point 1 corresponding to the slice #1 according to the configuration of the slice priority, does not search for a proper cell on the slice #1, determines that the triggering condition is met, and generates corresponding cell reselection related information-1.

Searching is carried out on the frequency point 2 corresponding to the slice #2, a proper cell is not searched on the slice #2, the triggering condition is confirmed to be met, and corresponding cell reselection related information-2 is generated.

An appropriate cell is searched for at the frequency point 3 corresponding to the slice#3, and at this time, the cell reselection related information may not be generated.

The cell reselection related information-1 may include: the terminal device performs cell reselection on the high priority slice and does not find the slice ID of the appropriate cell (slice # 1); the cell reselection related information-2 may include: the terminal device performs cell reselection on the high priority slice and does not find the slice ID of the appropriate cell, i.e. (slice # 2).

On this basis, the cell reselection related information-1 and the cell reselection related information-2 may each include at least one of the following: slice priority { slice#1) configured by network device: 5, slice#2:4, slice#3:3}; correspondence between frequency points configured by the network device and slices (corresponding to frequency point 1 of slice#1, corresponding to frequency point 2 of slice#2, corresponding to frequency point 3 of slice#3); the terminal device performs a location (longitude, latitude) before cell reselection; and the cell ID-1 where the terminal equipment currently resides.

It should be understood that, in either of the above processing manners, the terminal device may perform the processing of cell reselection based on the priority of the slice while in the RRC idle state (e.g., RRC idle state).

The cell reselection (cell reselection) refers to a process that the UE monitors signal quality of a neighboring cell and a current cell in an idle state to select a best cell to provide a service signal. When the signal quality and level of the neighbor cell meet the cell reselection criteria, accessing the cell to reside. The cell reselection criteria may be the following two ways, respectively:

Mode 1, inter-frequency cell reselection.

If threshServingLowQ (serving cell minimum threshold Q) is broadcasted in the system information and more than 1 second has passed since the terminal device camped on the current serving cell, the cell reselects to a cell on a higher priority NR (New Radio) frequency or Radio access technology (Radio Access Technology, RAT) frequency than the serving frequency, with a higher priority NR or EUTRAN (Evolved Universal Terrestrial Radio Access Network ) if the following conditions are met: the cells of the RAT/frequency meet the square > Thresh _X,HighQ during the time interval Treselection _RAT.

Otherwise, cell reselection will be performed on an NR frequency or inter-RAT frequency of higher priority than the serving frequency if at least one of the following conditions is met: cells with higher priority RATs/frequencies meet Srxlev > Thresh _X,HighP during time interval Treselection _RAT; the terminal device has been camping on the current serving cell for more than 1 second.

Cell reselection for cells on the same priority NR frequency should be based on the same frequency cell reselection ranking.

If threshServingLowQ is broadcast in the system information and more than 1 second has passed since the UE camps on the current serving cell, the cell reselects to a cell on an NR frequency or RAT frequency with priority lower than the serving frequency if the following conditions are met: the serving cell satisfies the square < Thresh _Serving, _LowQ and the cell with the lower priority NR or E-UTRAN RAT/frequency satisfies the square > Thresh _X,LowQ during the time interval Treselection _RAT.

Otherwise, cell reselection will be performed on a lower priority NR frequency or inter-RAT frequency than the serving frequency if the following condition is met: the serving cell satisfies Srxlev < Thresh _Serving,LowP and the lower priority RAT/frequency cell satisfies Srxlev > Thresh _X,LowP during time interval Treselection _RAT; the terminal device has been camping on the current serving cell for more than 1 second.

If multiple cells of different priorities meet the cell reselection criteria, then the cell reselection to a higher priority RAT/frequency should take precedence over a lower priority RAT/frequency.

If more than one cell meets the above criteria, the terminal device will reselect one cell as follows:

If the highest priority frequency is NR frequency, selecting the cell with the highest ranking from the cells on the highest priority frequency; if the highest priority frequency is from another RAT, the strongest cell of the cells on the highest priority frequency that meets the RAT criteria.

Mode 2, same frequency and equal priority different frequency cell reselection criteria.

The cell ranking criteria Rs of the serving cell and Rn of the neighboring cell are defined as:

Rs＝Q _meas,s+Q _hyst–Qoffset _temp

R _n＝Q _meas,n-Qoffset-Qoffset _temp

Wherein Q _meas is the RSRP measurement used in cell reselection. Q _offset, for intra-frequency: equal to Qoffset _s,n, if Qoffset _s,n is valid, otherwise equal to 0; for inter-frequency: equal to Qoffset _s,n plus Qoffset _frequency, if Qoffset _s,n is valid, otherwise equal to Qoffset _frequency.Qoffset _temp indicates the offset temporarily applied to the cell.

The terminal device will order all cells that meet the cell selection criteria S defined in the S criterion.

By deriving Qmeas, n and Qmeas, s and calculating the R value using the average RSRP result, the cells should be ordered according to the R criteria specified above.

If rangeToBestCell is not configured, the UE will perform cell reselection to the highest ranked cell. If the cell is found to be unsuitable, the terminal device should operate according to other specifications. If rangeToBestCell is configured, the UE will perform cell reselection to the cell with the highest number of beams above the threshold (i.e., absThreshSS-BlocksConsolidation), with an R value within rangeToBestCell of the highest ranked cell. If there are a plurality of such cells, the UE will perform a cell reselection to the highest ranked cell. If the cell is found to be unsuitable, the UE should operate in other prescribed ways.

In all cases, the terminal device will reselect to the new cell only if the following conditions are met: during time interval TreselectionRAT, the new cell is preferred over the serving cell according to the cell reselection criteria specified above; more than 1 second since the terminal device camps on the current serving cell.

After the above processing is completed, S310 may be performed in which the terminal device transmits information to the network in case of entering a connected state. Wherein, the sending information to the network may specifically refer to sending information to the network device. The network device may be an access network device corresponding to the terminal device, such as a base station, an eNB, a gNB, and so on. Wherein the information is carried by radio resource control, RRC, signaling.

Here, there may be two cases regarding the carrying manner of the cell reselection related information, respectively:

In the first case, the cell reselection related information is newly created information.

For example, a new report related to terminal reselection under the priority of recording slice, namely the above-mentioned cell reselection related information, can be created. And taking the new report related to the reselection of the terminal under the recording slice priority as the content of the information.

Correspondingly, when the terminal equipment is in a connection state, the information is carried in an RRC signaling and reported to the network equipment.

In the second case, the cell reselection related information is stored in a recorded measurement report.

Wherein the recorded measurement report may be specifically denoted logged measurement report. The logged measurement report logged measurement report may be information set during the logged MDT (or logged MDT).

Wherein Logged measurement report (recorded measurement report) may further include: absoluteTimeStamp (absolute timestamp), TRACEREFERENCE (trace reference), traceRecordingSessionRef (trace recording session reference), logMeasInfoList (record measurement list), logMeasAvailable (active measurement record), logMeasAvailableBT (bluetooth active measurement record), logMeasAvailableWLAN (WLAN active measurement record), and so on. Illustratively, the format of Logged measurement report (recorded measurement report) is as follows:

It should be appreciated that the above description of Logged measurement report (recorded measurement report) is merely exemplary, and does not represent Logged measurement report (recorded measurement report) that only the above may be included, but the present embodiment is not intended to be exhaustive.

In the second case of the present embodiment, the cell reselection related information may be added to Logged measurement report (the recorded measurement report). And then uses Logged measurement report (the recorded measurement report) as the content of the information.

It should be further noted that, when the network device receives the information reported by the terminal device, the network device may extract the cell reselection related information from the information, and adjust the priority of the slice based on the cell reselection related information.

The adjusting the priority of the slice based on the cell reselection related information may specifically include:

determining that a slice of a suitable cell is not found based on the cell reselection related information, and finding a slice of a suitable cell;

And adjusting the priority of the slice for finding the proper cell to be higher than the priority of the slice for not finding the proper cell.

For example, based on the cell reselection related information, determining that the slice IDs of the cells where no suitable cells are found are (slice#1 and slice#2); and determining that the slice ID of the cell which is found to be suitable is 'slice#3' based on the cell reselection related information.

The network device may adjust the priority of slice #3 to be higher than the priorities of slice #1 and slice # 2. For example, the slice priority before adjustment is configured to: { slice#1:5, slice#2:4, slice#3:3}, the adjusted slice priority is configured to: { slice#3:5, slice#1:4, slice#2:3,}.

In addition, other processing strategies may be set in the network device, for example, the network device may adjust the priority of the slice according to the received cell reselection related information reported by all the terminal devices, which may specifically be:

Determining that a slice of a proper cell is not found and finding the slice of the proper cell based on the cell reselection related information reported by all terminal equipment;

adjusting the priority of the slice for finding the suitable cell to be higher than the priority of the slice for not finding the suitable cell;

Sequencing the slices for finding the proper cells according to the reporting times; adjusting the priority of the slice for finding the proper cell based on the order of the order from high to low;

the slices which do not find the proper cells are sequenced according to the reporting times; the priority of the slices for which no suitable cell is found is adjusted based on the order of the rank from low to high.

For example, slice IDs of cells for which no suitable cell is found are determined to be slice#1, slice#2, slice#4, and slice#5 based on cell reselection related information reported by all terminal devices; . And determining slice IDs of the cells which are found to be suitable as slice #3 and slice #6 based on the cell reselection related information reported by all the terminal devices.

The network device may adjust the priorities of slice #3 and slice #6 to be higher than the priorities of slice #1, slice #2, slice #4, and slice # 5.

Further, the network device determines priorities of slice#3 and slice#6 based on an order of high to low reporting times of slice#3 and slice#6. For example, if the number of times of reporting the slice#3 is 10 and the number of times of reporting the slice#6 is 7, the adjusted priority is that the slice#3 is higher than the slice#6.

In addition, the network device may also adjust priorities of slice#1, slice#2, slice#4, and slice#5 based on the order of the reporting times from low to high. For example, if slice#1, slice#2, slice#4, and slice#5 are reported 10 times, 5 times, 1 time, and 3 times, respectively, the adjusted priority may be slice#4> slice#5> slice#2> slice#1.

Based on the above example, the adjusted slice priority configuration obtained by the network device may be: { slice#3:6, slice#6:5, slice#4:4, slice#5:3, slice#2:2, slice#1:1}.

Further, the network device may retransmit the adjusted slice priority configuration for the terminal device. For example, the network device may send the adjusted slice priority configuration to the terminal device through RRC signaling when the terminal device is in an RRC connected state.

By adopting the scheme, the terminal equipment can generate the cell reselection related information when the cell reselection is performed based on the priority of the slice, and then the terminal equipment sends the information containing the cell reselection related information to the network under the condition of entering the connection state. Therefore, the network side can adjust the priority of the slice based on the cell reselection related information, and then the slice priority configuration can be updated, so that the network device can be assisted to reasonably configure the slice priority, the time required for searching is reduced when the terminal device performs cell reselection based on the priority of the slice, and the efficiency of the terminal device for finding a proper cell is improved.
