Description

Method, device and medium for determining RRM measurement mode of non-connected terminal in NTN

technical field

The embodiment of the present application relates to satellite communication technology, and in particular to a method, device and medium for determining an RRM measurement mode of a terminal in a non-connected state in NTN.

Background technique

Currently, the 3rd Generation Partnership Project (3GPP) is researching the Non Terrestrial Network (NTN) technology, which generally uses satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's region. For example, general land communication cannot cover areas such as oceans, mountains, deserts, etc. that cannot be equipped with communication equipment or are not covered by communication due to sparse population. For satellite communication, due to a Satellites can cover a large area of the ground, and satellites can orbit the earth, so theoretically every corner of the earth can be covered by satellite communications.

For non-Geostationary Earth Orbit (Geostationary Earth Orbit, GEO) scenarios in NTN (such as Low-Earth Orbit (Low-Earth Orbit, abbreviated: LEO), Medium-Earth Orbit (Medium-Earth Orbit, abbreviated: MEO), etc.), Including earth moving cell and quasi-earth fixed cell two scenarios. earth moving cell means that the direction of the satellite beam remains unchanged, and the ground cell under satellite coverage moves with the movement of the satellite; The ground cell of the plot remains constant for a period of time.

Based on the conclusions of the current Radio Access Network (RAN) 2 meeting, for the quasi-earth fixed cell scenario, the network can broadcast a t-Service, which is used to indicate the time when the NTN cell stops serving the current coverage area. This parameter will affect the UE's measurement behavior for neighboring cells. Specifically, if the network broadcasts t-Service, the UE must start the wireless measurement for neighboring cells before t-Service, regardless of whether the UE meets the conditions for starting neighboring cell measurement. Radio Resource Management (RRM) measurement.

However, in the above scenario, if the network configures the RRM measurement relaxation criterion for RRC unconnected state, then for a UE that meets the RRM measurement relaxation criterion, how does the UE perform the measurement of the neighbor cell before t-Service? There is no related technical solution yet.

Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Among the common application scenarios of 5G, Enhanced Mobile Broadband (eMBB for short) is still aimed at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of Ultra Reliable Low Latency Communications (URLLC for short) include: industrial automation, power automation, telemedicine operations (surgery), traffic safety assurance, etc. Typical features of massive Machine Type Communications (mMTC for short) include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new Radio Resource Control (RRC) state is defined, namely the RRC_INACTIVE state. This state is different from the RRC_IDLE and RRC_CONNECTED states. The following takes User Equipment (UE) as the user-side device and the base station as the network device as examples to introduce these states:

Idle state (RRC_IDLE): mobility is UE-based cell selection and reselection, paging is initiated by CN, and paging area is configured by CN. There is no UE AS context on the base station side. There is no RRC connection.

Connected state (RRC_CONNECTED): There is an RRC connection, and the UE AS context exists between the base station and the UE. The network side knows the location of the UE at the specific cell level. Mobility is mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

Inactive state (RRC_INACTIVE): Mobility is UE-based cell selection and reselection, there is a connection between CN-NG-RAN, UE AS context exists on a certain base station, and paging is performed by the radio access network (Radio Access Network, Abbreviation: RAN) triggering, the RAN-based paging area is managed by the RAN, and the network side knows the location of the UE based on the RAN paging area level.

Radio Resource Management (RRM for short) measurement of UE in unconnected state in R15NR:

A UE in a non-connected state needs to perform RRM measurements on the serving cell and other neighboring cells based on network configuration to support mobility operations, such as cell reselection.

The UE in the unconnected state continuously performs measurement on the serving cell.

In NR Rel-15, for the consideration of UE energy saving, when the quality channel of the UE in the serving cell is good, the UE may not start the different frequency/different technology frequency point for the same frequency point and the same priority or low priority The RRM measurement of RRM can perform relaxed RRM measurement for priority inter-frequency/inter-technology frequency points. in particular:

For the same-frequency frequency point, if the Srxlev measured by the serving cell is higher than SIntraSearchP and Squal SIntraSearchQ, the UE can turn off the measurement of all same-frequency neighboring cells.

For low-priority or equal-priority NR inter-frequency or different-technology frequency points, if the Srxlev measured by the serving cell is higher than SnonIntraSearchP and Squal is higher than SnonIntraSearchQ, the UE can turn off all low-priority or equal-priority NR inter-frequency Measurement of point or frequency points of different technologies.

For high-priority NR inter-frequency or inter-technology frequency points, if the Srxlev measured by the serving cell is higher than SnonIntraSearchP and Squal is higher than SnonIntraSearchQ, the UE can perform relaxed for high-priority NR inter-frequency or inter-technology frequency points For measurement, at this time, for each high-priority frequency point, the measurement interval is relaxed as Thigher_priority_search=(60*Nlayers)s, where Nlayers is the number of high-priority frequency points broadcast by the network.

Among them, the parameters SIntraSearchP, SIntraSearchQ, SnonIntraSearchP and SnonIntraSearchQ are configured by the network through SIB2.

In New Radio (NR for short), cell measurement requirements include Tdetect, Tmeasure, and Tevaluate, which are respectively aimed at the time used for cell detection, cell measurement, and cell evaluation. Usually, these requirements and terminal discontinuous reception (Discontinuous Reception, Abbreviation: DRX) cycle correlation.

In R16NR, the content of the RRM measurement relaxation of the UE in the unconnected state:

R16 introduces a relaxation mechanism for neighbor cell measurement for non-connected UEs to further meet the needs of terminals for power saving.

In order to support relaxed neighbor cell measurement, the low mobility (English: low mobility) criterion and the not-at-cell-edge (English: not-at-cell-edge) criterion are introduced. These two sets of criteria are measured by the measurement results of the UE on the serving cell. The definition of the low mobility criterion and the not-at-cell-edge criterion in the standard is as follows:

"low mobility" guidelines

According to this criterion, the network will configure the reference signal received power (English: Reference Signal Received Power, abbreviated: RSRP) change evaluation duration TSearchDeltaP and RSRP change value threshold SSearchDeltaP. When the RSRP variation of the UE on the serving cell within TSearchDeltaP is less than SSearchDeltaP for a period of time, the UE is considered to meet the "low mobility" criterion. That is: within a period of TSearchDeltaP, satisfy:

(SrxlevRef–Srxlev)<SSearchDeltaP formula<1>

Where: Srxlev is the current Srxlev measurement value of the serving cell, and SrxlevRef is the reference Srxlev value of the serving cell.

When the UE selects or reselects to a new cell; or,

if (Srxlev-SrxlevRef)>0; or,

If the UE does not satisfy the formula <1> within the continuous TSearchDeltaP time: the UE sets SrxlevRef as the current Srxlev measurement value of the serving cell;

After completing cell selection/reselection, the UE needs to perform normal RRM measurement for at least a period of TSearchDeltaP.

"not-at-cell-edge" guidelines

According to this criterion, the network will configure an RSRP threshold SSearchThresholdP, and an RSRQ threshold SSearchThresholdQ can also be configured. When the RSRP of the UE on the serving cell is greater than the RSRP threshold, and the network is configured with Reference Signal Received Quality : RSRQ) threshold, when the RSRQ of the UE on the serving cell is greater than the RSRQ threshold, the UE is considered to meet the "not-at-cell-edge" criterion.

The network notifies the UE whether the RRM measurement relaxation function can be enabled through a system broadcast. When the RRM measurement relaxation function is enabled, the network needs to configure at least one RRM measurement relaxation judgment criterion. For different configurations, the following four situations may exist:

case1: The network only configures the low mobility criterion. At this time, when the UE meets the low mobility criterion, the UE starts relaxed RRM measurement for the neighboring cell.

case2: The network only configures the not-at-cell-edge criterion, and when the UE satisfies the not-at-cell-edge criterion, the UE performs relaxed RRM measurement for neighboring cells.

case3: The network configures the low mobility criterion and the not-at-cell-edge criterion at the same time, and the network does not configure the parameter combineRelaxedMeasCondition. At this time, when the UE meets at least one of the two criteria, the UE starts relaxed RRM for the neighboring cell Measurement.

case4: The network configures the low mobility criterion and the not-at-cell-edge criterion at the same time, and the network configures the parameter combineRelaxedMeasCondition. At this time, when the UE meets these two criteria at the same time, the UE starts relaxed RRM measurement for the neighboring cell.

In addition, TS38.133 defines the following two RRM measurement relaxation methods for unconnected UEs:

Method 1: When the UE only meets the low mobility criterion or the not-at-cell-edge criterion, for intra-frequency measurement, NR inter-frequency measurement and inter-technology inter-frequency measurement, relax the measurement interval to 3 times the normal measurement interval.

Method 2: When the UE meets both the low mobility criterion and the not-at-cell-edge criterion, the measurement interval can be relaxed to 1 hour for intra-frequency measurement, NR inter-frequency measurement and inter-technology inter-frequency measurement.

In addition, highPriorityMeasRelax is introduced for high-priority frequency points, which is used to indicate whether the network allows the UE to relax the measurement interval of high-priority frequency points to exceed the Thigher_priority_search value (UE meets both the low mobility criterion and the not-at-cell -edge criterion except in the case). In other words, highPriorityMeasRelax is only used when the control network is only configured with the low mobility criterion and the UE meets the low mobility criterion, and the measurement result of the UE in the serving cell satisfies that Srxlev is greater than SnonIntraSearchP and Squal is greater than SnonIntraSearchQ. In this case, if the network configures highPriorityMeasRelax, the UE's measurement interval for high priority frequency points can be relaxed to K2*Thigher_priority_search, where K2 is 60; otherwise (if the network does not have highPriorityMeasRelax), UE measures for high priority frequency points Points are measured at Thigher_priority_search interval.

On the basis of the R16 low mobility and not cell edge criteria, R17 further studies the RRM measurement relaxation for stationary terminals. The current standard discussion has reached the following clear conclusions:

1. In R17, the static (English: stationary) criterion reuses the R16 low mobility criterion, and the network configures different thresholds (English: threshold) for these two criteria.

2. If the network needs to configure the RRM relaxation criterion for R17 unconnected UEs, the R17 stationary criterion is a mandatory configuration, and the R17 not cell edge criterion is an optional configuration.

In summary, in the current NR standard, the RRM measurement relaxation criteria mainly include the following three criteria:

Low mobility criterion, that is, Low mobility criterion;

Static criterion, that is, Stationary criterion;

Not in the cell center criterion, that is, the Not-at-cell-edge criterion.

The RRM measurement relaxation criterion referred to in the embodiment of the present application is also at least one of the above three criteria.

With the increasing demand for wireless network technology, 3GPP is researching Non Terrestrial Network (NTN) technology. NTN generally uses satellite communication to provide communication services to ground users. Satellites can be divided into Geostationary Earth Orbiting (GEO)/Medium Earth Orbiting (MEO)/Low Earth Orbiting (LEO). GEO covers thousands of kilometers in diameter ( Usually 3 satellites cover the whole world), relatively stationary to the ground, while MEO/LEO covers diameters ranging from tens of kilometers to thousands of kilometers depending on the orbital height, while ground cells usually cover hundreds of meters to thousands of kilometers in diameter meters, the coverage of satellite cells is much larger than that of ground cells.

In the current technical solution, the non-GEO scenarios (such as LEO, MEO, etc.) in NTN include two scenarios: earth moving cell and quasi-earth fixed cell. earth moving cell means that the direction of the satellite beam remains unchanged, and the ground cell under satellite coverage moves with the movement of the satellite; The ground cell of the plot remains constant for a period of time.

Based on the conclusions of the current RAN2 meeting, for the quasi-earth fixed cell scenario, the network can broadcast a t-Service, which is used to indicate the time when the NTN cell stops serving the current coverage area. Specifically, the definition of t-Service in the protocol is "Indicates the time information on when a cell provided via NTN quasi-Earth fixed system is going to stop serving the area it is currently covering.". This parameter will affect the UE's measurement behavior for neighboring cells. Specifically, if the network broadcasts t-Service, the UE must start RRM for neighboring cells before t-Service, regardless of whether the UE meets the conditions for starting neighboring cell measurement. Measurement. However, if the network configures RRM measurement relaxation criteria for RRC disconnected state, then for UEs that meet RRM measurement relaxation, the UE can always perform relaxed RRM measurement for neighboring cells before t-Service or it needs to follow normal The measurement requires the execution of neighbor cell measurement, which has not been discussed in the current solution, and no specific processing solution has been given.

In view of the above problems, this solution provides a solution of how to perform RRM measurement after receiving t-Service in RRC unconnected state and satisfying the RRM measurement relaxation criterion. This solution can be applied to various types of satellite network architectures.

Figure 1 is a schematic diagram of the transparent forwarding satellite network architecture provided by the embodiment of the present application. As shown in Figure 1, in the transparent forwarding satellite network architecture, a base station needs to be set up separately, and the network is carried out through the interaction between the base station, the satellite and the UE Data forwarding interaction. Satellites and ground stations form a remote wireless unit (English: Remote Radio Unit).

Figure 2 is a schematic diagram of the regenerative and forwarding satellite network architecture provided by the embodiment of the present application. As shown in Figure 2, in the regenerative and forwarding satellite network architecture, there is no need to set up a separate base station, and the network communicates with the UE through the base station function set inside the satellite. Interaction between data forwarding interaction.

In the above two architectures, the wireless link between the satellite and the ground station (NTN gateway, usually located on the ground) can be called a feeder link.

On the basis of the above-mentioned satellite network architecture, it should be understood that the technical solution of the present application is mainly applied to two execution entities of network equipment and terminal equipment. The network device performs configuration related to measurement, and the terminal device determines how to perform measurement according to the configuration of the network device. The network device can provide communication coverage for a specific geographical area, and can communicate with terminal devices located in the coverage area. In the scenario of the present application, the network device is a base station providing satellite services, which may be a base station installed separately or installed in a satellite, and this solution does not limit this.

Terminal equipment includes, but is not limited to, devices that communicate via data connections/networks and/or via wireless interfaces, e.g. for cellular networks, Wireless Local Area Networks (WLAN), digital television networks such as DVB-H networks, satellite A network, an AM-FM broadcast transmitter; and/or another device configured to receive/transmit communication signals; and/or an Internet of Things (IoT) device. A terminal device arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; Personal Communications System (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data communication capabilities; may include radiotelephones, pagers, Internet/Internet PDAs with network access, web browsers, organizers, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic device. Can refer to an access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a wireless communication Functional handheld devices, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks, terminal devices in satellite networks, or terminal devices in future evolved PLMNs, etc., for this This program is not limited.

The following describes in detail the method for determining the RRM measurement mode of the terminal in the NTN in the non-connected state provided by the present application through several specific embodiments.

Fig. 3 is the flow chart of Embodiment 1 of the method for determining the RRM measurement mode of a non-connected state terminal in the NTN of the embodiment of the present application. As shown in Fig. 3, the method specifically includes the following steps:

S101: Configure measurement configuration information, where the measurement configuration information includes the time when the NTN cell stops serving the current coverage area.

In this step, for the network equipment, as the satellite moves, the NTN cell currently serving some terminal equipment may leave the current coverage area after a period of time, that is, it cannot continue to provide signal coverage for the equipment in the current coverage area At this time, the network device can determine the time when the NTN cell stops serving the current coverage area according to the movement of the satellite. The time when the NTN cell stops serving the current coverage area refers to the time when the NTN cell leaves the current coverage area. That is t-Service (the meaning is: Indicates the time information on when a cell provided via NTN quasi-Earth fixed system is going to stop serving the area it is currently covering).

S102: Broadcast measurement configuration information.

After the network device determines the time when the NTN cell stops serving the current coverage area, it broadcasts the time when the NTN cell stops serving the current coverage area through the system broadcast, that is, all terminal devices within the coverage area of the NTN cell can receive the network The measurement configuration information broadcast by the device.

S103: Receive measurement configuration information broadcast by the network device, where the measurement configuration information includes the time when the NTN cell stops serving the current coverage area.

In this step, taking any terminal device as an example, the terminal device receives the system broadcast message and receives the NTN cell broadcast by the network device to stop serving the current coverage area time (t-Service). Based on the t-Service, the terminal device can determine that the currently serving NTN cell will stop serving after t-Service, so for the terminal device, it is necessary to measure the neighboring cells before the current NTN cell stops serving the current coverage area, so that After the current NTN cell stops serving, it can access other cells to avoid wireless network interruption.

S104: If the terminal device satisfies the RRM measurement relaxation criterion, determine the RRM measurement mode for the neighboring cell before the time when the NTN cell stops serving the current coverage area according to the measurement configuration information.

In the technical solution of the present application, the RRM measurement manner at least includes RRM normal measurement or RRM relaxation measurement.

In this step, when the terminal device in the radio resource control (Radio Resource Control, referred to as: RRC) unconnected state is pre-configured with the RRM measurement relaxation criterion, after receiving the measurement configuration information broadcast by the network device, determine whether the RRM is satisfied Measure relaxation criteria.

If the terminal device does not satisfy the RRM measurement relaxation criterion, it only needs to perform normal measurement on the neighboring cells directly. However, if the terminal device meets the RRM measurement relaxation criterion, it needs to determine whether to perform normal measurement or RRM relaxation measurement on the neighbor cell before the time when the NTN cell stops serving the current coverage area according to the measurement configuration information configured by the network device.

In the specific implementation of this step, this application provides the following implementation methods:

The first implementation mode, for a terminal device in the RRC disconnected state, as long as the network device broadcasts and the terminal device receives the t-Service, no matter whether the terminal meets the RRM measurement relaxation criteria, the neighbor cell will be measured before the t-Service according to the Normal measurement requires RRM measurement, that is, normal RRM measurement is performed before t-Service.

In the second implementation mode, the network device also configures another RRM measurement relaxation indication information (that is, the Allowed-RRM-relax indication information), which is used to indicate whether to allow a terminal device that meets the RRM measurement relaxation criterion to stop serving the current coverage in the NTN cell RRM relaxation measurements are performed for neighboring cells before the time of the region.

For a terminal device that is in the RRC disconnected state and meets the RRM measurement relaxation criterion, it needs to determine whether to use RRM normal measurement or RRM measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area according to the RRM measurement relaxation indication information. RRM relaxation measure.

In specific implementation, if the RRM measurement relaxation indication information indicates that a terminal device that meets the RRM measurement relaxation criteria is allowed to perform RRM relaxation measurement for neighboring cells before the time when the NTN cell stops serving the current coverage area, then the terminal device stops serving the current coverage area in the NTN cell. Before the time of the area, you can continue to perform RRM relaxation measurement on the neighboring cell; otherwise, if the RRM measurement relaxation indication information indicates that the terminal device that meets the RRM measurement relaxation criterion is not allowed to perform RRM relaxation on the neighboring cell before the time when the NTN cell stops serving the current coverage area measurement, then the terminal equipment needs to restore the adjacent cell to perform RRM normal measurement before the time when the NTN cell stops serving the current coverage area, that is, perform RRM measurement according to the normal measurement requirements.

Further, after determining the measurement manner, the terminal device may perform RRM measurement on neighboring cells according to the determined manner.

It should be understood that, in all the embodiments of the present application, the RRM measurement relaxation criterion may include at least one criterion among the low mobility criterion, the static criterion and the not-in-cell-center criterion, and this solution is not limited thereto.

The method for determining the RRM measurement method of a non-connected terminal in NTN provided in this embodiment provides an RRC non-connected terminal device, how to perform RRM measurement on a neighboring cell after receiving the time when the NTN cell stops serving the current coverage area solution, the terminal device can measure neighboring cells according to the above-mentioned solution, determine a suitable candidate neighboring cell as soon as possible, and can access a suitable candidate neighboring cell after the currently serving NTN cell stops serving.

Based on the above-mentioned embodiments, in a specific implementation of the method for determining the RRM measurement method of a terminal in an unconnected state in NTN provided by this application, for an NTN cell, if the network device broadcasts the time when the NTN cell stops serving the current coverage area, Then no matter whether the terminal device meets the RRM measurement relaxation criterion, it must perform RRM measurement for the neighboring cell according to the normal measurement requirements before the time when the NTN cell stops serving the current coverage area (that is, the terminal device does not perform relaxed RRM measurement for the neighboring cell ).

The execution process of the terminal device is as follows:

1. The terminal device in the NTN cell receives the time (t-Service) at which the NTN cell stops serving the current coverage area broadcast by the network device.

2. For a terminal device in the RRC non-connected state, if the network device broadcasts a t-Service, no matter whether the terminal device meets the RRM measurement relaxation criteria, it must perform normal measurement requirements for neighboring cells before the t-Service RRM measurement. That is, for a terminal device that does not meet the RRM measurement relaxation criteria, it is enough to continue to perform RRM measurement for the neighboring cell according to the normal measurement requirements before the t-Service. For a terminal device that satisfies the RRM measurement relaxation criterion, the terminal device shall return to perform RRM measurement for the neighboring cell according to the normal measurement requirement before the t-Service.

FIG. 4 is a schematic diagram of RRM measurement of a terminal device that satisfies the RRM measurement relaxation criterion provided in an embodiment of the present application. As shown in FIG. 4 , the terminal device that satisfies the RRM measurement relaxation criterion has been performing relaxed RRM measurement before T0, And when T0 receives the time t-Service when the NTN cell stops serving the current coverage area, the terminal device needs to resume performing RRM measurement on neighboring cells according to the normal measurement requirements during the period between T0 and t-Service.

In a specific implementation, the specific time point at which the terminal device recovers to perform RRM measurement according to the normal measurement requirements for the neighboring cells may depend on the implementation of the terminal device.

In the solution provided by this embodiment, if the network device broadcasts the t-Service, no matter whether the terminal device satisfies the RRM measurement relaxation criterion, RRM measurement must be performed on the neighboring cells according to the normal measurement requirements before the t-Service. Using this method, the terminal device can find a suitable candidate neighbor cell as soon as possible through neighbor cell measurement before the current NTN cell stops providing services, thereby shortening the time for the terminal device to reselect to another cell after the current cell leaves, and can better To meet the requirements of terminal mobility management.

Fig. 5 is a flow chart of an example of a method for determining the RRM measurement method of a terminal in a non-connected state in the NTN of the embodiment of the present application. As shown in Fig. 5, on the basis of the first embodiment above, this embodiment provides another implementation solution, For an NTN cell, if the network device broadcasts the time when the cell stops serving the current coverage area, then for a terminal device that meets the RRM measurement relaxation criteria, it is determined based on other configurations of the network device whether to For the neighbor cell, restore to perform RRM measurement according to the normal measurement requirement (that is, do not perform relaxed RRM measurement for the neighbor cell). Specifically, the program includes the following steps:

S201: The network device configures the time for the NTN cell to stop serving the current coverage area.

S202: The network device configures RRM measurement relaxation indication information.

In the above two steps, the network device not only configures the time when the NTN cell stops serving the current coverage area, but also configures whether to allow the terminal device that meets the RRM measurement relaxation criteria to target neighboring cells before the time when the NTN cell stops serving the current coverage area. RRM measurement relaxation indication information for performing RRM relaxation measurement.

That is to say, the measurement configuration information configured by the network device includes the time when the NTN cell stops serving the current coverage area and RRM measurement relaxation indication information. The network device broadcasts the measurement configuration information to the terminal device through system broadcast.

In a specific implementation of this solution, the network device can simultaneously configure the time when the NTN cell stops serving the current coverage area and the RRM measurement relaxation indication information, and broadcast the measurement configuration information to the terminal device at the same time. The network device can also configure the RRM measurement relaxation instruction information after configuring the time when the NTN cell stops serving the current coverage area, and then broadcast the time when the NTN cell stops serving the current coverage area and the RRM measurement relaxation instruction information to the terminal through a system broadcast The device can also broadcast the time when the NTN cell stops serving the current coverage area and the RRM measurement relaxation instruction information to the terminal device through different system broadcasts, which is not limited in this solution.

In the specific implementation of this solution, it should be understood that the network device can configure the RRM measurement relaxation indication information only under the premise of configuring the time for the NTN cell to stop serving the current coverage area.

S203: The RRM measurement relaxation indication information indicates whether to allow the terminal equipment satisfying the RRM measurement relaxation criterion to perform RRM relaxation measurement for the neighbor cell before the time when the NTN cell stops serving the current coverage area.

In this step, for the terminal equipment, after receiving the time when the NTN cell stops serving the current coverage area broadcast by the network equipment and the RRM measurement relaxation indication information, for the terminal equipment in the RRC disconnected state, if the network equipment broadcasts If the time t-Service during which the NTN cell stops serving the current coverage area is exceeded, and the terminal device meets the RRM measurement relaxation criterion, the terminal device determines whether to use the RRM measurement relaxation indication information (Allowed-RRM-relax indication information) configured in the network. t-Service has restored to perform RRM measurement according to the normal measurement requirements for neighboring cells.

S204: If the RRM measurement relaxation indication information indicates that the terminal device that meets the RRM measurement relaxation criterion is allowed to perform RRM relaxation measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area, then perform RRM measurement relaxation for the neighboring cell before the time when the NTN cell stops serving the current coverage area. Neighboring cells use RRM relaxation measurement.

S205: If the RRM measurement relaxation indication information indicates that the terminal equipment satisfying the RRM measurement relaxation criterion is not allowed to perform RRM relaxation measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area, then before the time when the NTN cell stops serving the current coverage area Normal RRM measurement is used for neighboring cells.

In the above two steps, it can be seen that if the Allowed-RRM-relax indication information indicates that the terminal device that is not allowed to meet the RRM measurement relaxation criterion can perform relaxed RRM measurement for the neighboring cell before t-Service, then: for satisfying the RRM measurement For the terminal equipment whose criterion is relaxed, the terminal equipment needs to return to performing RRM measurement according to the normal measurement requirements for the neighboring cells before t-Service, that is, adopt the normal RRM measurement.

If the Allowed-RRM-relax indication indicates that UEs that meet the RRM measurement relaxation criteria are allowed to perform relaxed RRM measurements on neighboring cells before t-Service, then: for a terminal device that meets the RRM measurement relaxation criteria, the terminal device can perform Neighboring cells perform relaxed RRM measurement (that is, the behavior of RRM measurement relaxation only depends on whether the terminal device meets the RRM measurement relaxation criterion, and will not be affected by t-Service).

Similar to the foregoing embodiments, the time point at which the terminal device recovers to perform RRM measurement according to the normal measurement requirements for neighboring cells may depend on the specific implementation of the terminal device, which is not specifically limited in this solution.

In a specific implementation of this embodiment, the configuration of the Allowed-RRM-relax indication information by the network device may be implemented in the following situations:

Case 1: The network device configures the Allowed-RRM-relax indication information with different indication values. For example: the Allowed-RRM-relax indication information is configured as the first indication value indicating that a terminal device that meets the RRM measurement relaxation criterion is allowed to perform RRM relaxation measurement on neighboring cells before the time when the NTN cell stops serving the current coverage area, and the Allowed-RRM-relax indication The information is configured as the second indication value indicating that the terminal device satisfying the RRM measurement relaxation criterion is not allowed to perform RRM relaxation measurement on the neighbor cell before the time when the NTN cell stops serving the current coverage area. Specifically, it may be configured that when the RRM measurement relaxation indication information is 1, it indicates that a terminal device that meets the RRM measurement relaxation criterion is allowed to perform RRM relaxation measurement on a neighboring cell before the NTN cell stops serving the current coverage area. When the RRM measurement relaxation indication information is 0, it indicates that the terminal device satisfying the RRM measurement relaxation criterion is not allowed to perform RRM relaxation measurement on the neighboring cell before the time when the NTN cell stops serving the current coverage area.

Optionally, the RRM measurement relaxation indication information is 0 to indicate permission, and the RRM measurement relaxation indication information is 1 to indicate disallowance, which is not limited in this solution.

In the second case, the network device can realize whether to allow the terminal device that meets the RRM measurement relaxation criterion to perform RRM relaxation measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area by configuring the Allowed-RRM-relax indication information specifically. instruct. Specifically, if the network configures the RRM measurement relaxation indication information, it indicates that the terminal device that meets the RRM measurement relaxation criterion is allowed to perform RRM relaxation measurement for the neighboring cell before the time when the NTN cell stops serving the current coverage area; if the network does not configure RRM The measurement relaxation instruction information indicates that the terminal device satisfying the RRM measurement relaxation criterion is not allowed to perform RRM relaxation measurement on the neighbor cell before the time when the NTN cell stops serving the current coverage area.

It means that if the network device does not configure the specific content of the RRM measurement relaxation indication information, it means that the terminal device that meets the RRM measurement relaxation criterion is not allowed to continue to perform RRM relaxation measurement on the neighboring cell before the time when the NTN cell stops serving the current coverage area , need to resume normal RRM measurement.

In the method for determining the RRM measurement mode of a non-connected terminal in NTN provided by the embodiment of this application, the RRM measurement relaxation criterion for the RRC non-connected state is configured on the network device, then for the terminal device that meets the RRM measurement relaxation, before t-Service For the measurement of neighboring cells, whether the relaxed RRM measurement can be performed all the time or the neighboring cell measurement needs to be performed according to the normal measurement requirements, several specific implementation schemes are provided. Through these schemes, the RRM measurement of the neighboring cells is performed, and the service is stopped in the current NTN cell Then find a suitable candidate neighboring cell as soon as possible, and continue to provide network services for the terminal equipment.
