Detailed ways

In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

The network architecture and business scenarios described in the embodiments of this application are to more clearly explain the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. Those of ordinary skill in the art will know that with the network architecture evolution and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

Please refer to Figure 1, which shows a schematic diagram of a network architecture provided by an embodiment of the present application. The network architecture may include: network device 10 and terminal device 20.

The network device 10 is a device used to provide wireless communication services to the terminal device 20 . A connection can be established between the network device 10 and the terminal device 20 through an air interface, so that communication, including signaling and data interaction, can be performed through the connection. The number of network devices 10 may be multiple, and communication between two adjacent network devices 10 may also be carried out in a wired or wireless manner. The terminal device 20 can switch between different network devices 10 , that is, establish connections with different network devices 10 .

In one example, as shown in Figure 2, taking NTN as an example, the network device 10 in the NTN may be a satellite 11. A satellite 11 can cover a certain range of ground area and provide wireless communication services to terminal devices 20 on the ground area. In addition, the satellite 11 can orbit the earth, and by deploying multiple satellites 11, communication coverage of different areas on the earth's surface can be achieved.

Compared with terrestrial cellular communication networks, satellite communications have many unique advantages. First of all, satellite communication is not restricted by the user's geographical area. For example, general land communication cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be installed or where communication coverage is not available due to sparse population. However, for satellite communication, due to a satellite 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. Secondly, satellite communications have great social value. Satellite communications can cover remote mountainous areas and poor and backward countries or regions at a lower cost, allowing people in these areas to enjoy advanced voice communications and mobile Internet technologies, which is conducive to narrowing the digital divide with developed regions and promoting development in these areas. Thirdly, satellite communication has a long distance, and the cost of communication does not increase significantly as the communication distance increases; finally, satellite communication has high stability and is not restricted by natural disasters.

Communication satellites are divided into LEO (Low-Earth Orbit, low Earth orbit) satellites, MEO (Medium-Earth Orbit, medium Earth orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous orbit) satellites, HEO (High Earth Orbit) satellites according to different orbital altitudes. Elliptical Orbit, highly elliptical orbit) satellite, etc. At the current stage, the main research is on LEO and GEO. The altitude range of LEO is 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the transmission power requirements of the user terminal are not high. GEO's orbital altitude is 35,786km and its rotation period around the Earth is 24 hours. The signal propagation delay for single-hop communication between users is generally 250ms.

In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. One satellite can form dozens or even hundreds of beams to cover the ground; one satellite beam can cover dozens to hundreds of kilometers in diameter. Ground area.

In another example, as shown in FIG. 3 , taking a cellular communication network as an example, the network device 10 in the cellular communication network may be a base station 12 (or called an access network device). The base station 12 is a device deployed in the access network to provide wireless communication functions for the terminal device 20 . The base station 12 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in 5G NR (New Radio, New Radio) systems, they are called gNodeB or gNB. As communications technology evolves, the name "base station" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 20 are collectively referred to as network devices.

In addition, the terminal device 20 involved in the embodiment of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of users. Equipment (User Equipment, UE), mobile station (Mobile Station, MS), terminal device (terminal device), etc. For convenience of description, in the embodiments of this application, the above-mentioned devices are collectively referred to as terminal devices.

In addition, in the embodiments of this application, the nouns "network" and "system" are often used interchangeably, and the nouns "terminal equipment" and "UE" are often used interchangeably, but those skilled in the art can understand their meanings.

Before introducing the technical solutions of this application, some background technical knowledge involved in this application will be introduced and explained. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following contents.

1. RRC (Radio Resource Control, Radio Resource Control) status in the NR system

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP (3rd Generation Partner Project) international standards organization began to develop 5G. The main application scenarios of 5G are: eMBB (Enhanced Mobile Broadband, enhanced mobile ultra-broadband), URLLC (Ultra-reliable and Low Latency Communications, low-latency and high-reliability communications), mMTC (Massive Machine Type of Communication, large-scale machine type communications) ).

In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC state is defined, namely the RRC_INACTIVE (RRC inactive state) state. This state is different from the RRC_IDLE (RRC idle state) and RRC_CONNECTED (RRC connected state) states.

RRC_IDLE (abbreviated as "IDLE state" or "idle state"): Mobility is UE-based cell selection and reselection. Paging is initiated by CN (Core Network), and the paging area is configured by CN. There is no UE AS (Access Stratum, access layer) context on the base station side. There is no RRC connection.

RRC_CONNECTED (referred to as "CONNECTED state" or "connected state"): There is an RRC connection, and the base station and the UE have a UE AS context. The network side knows the location of the UE at the specific cell level. Mobility is network-side controlled mobility. Unicast data can be transmitted between the UE and the base station.

RRC_INACTIVE (abbreviated as "INACTIVE state" or "inactive state"): Mobility is UE-based cell selection and reselection. There is a connection between the core network and the RAN. The UE AS context exists on the anchor base station, and paging is performed by the RAN. Triggered, the RAN-based paging area is managed by the RAN, and the network side knows that the location of the UE is based on the RAN paging area level.

2. Measurement start of IDLE state and INACTIVE state

The neighbor cell measurement behavior of the UE in the IDLE state and INACTIVE state is subject to the relevant parameters in the system broadcast message. For example:

For the startup of co-frequency measurement, when the serving cell Srxlev>SIntraSearchP and the serving cell Squal>SIntraSearchQ, the co-frequency neighbor cell measurement is not started, otherwise the co-frequency neighbor cell measurement is started;

For inter-frequency measurement of the same priority or low priority, when the serving cell Srxlev>SnonIntraSearchP and the serving cell Squal>SnonIntraSearchQ, the inter-frequency measurement of the same priority or low priority will not be started, otherwise it will be started;

For high-priority inter-frequency measurements, the measurement is always started;

Among them, Srxlev is the measured value of RSRP (Reference Signal Receiving Power, reference signal receiving power), Squal is the measured value of RSRQ (Reference Signal Receiving Quality, reference signal receiving quality), and SIntraSearchP is the RSRP threshold used to start the same frequency measurement. value, SIntraSearchQ is the RSRQ threshold used to start intra-frequency measurement, SnonIntraSearchP is the RSRP threshold used to start inter-frequency measurement, and SnonIntraSearchQ is the RSRQ threshold used to start inter-frequency measurement.

For terminal equipment, TN (Terrestrial Network, terrestrial network) cells have stronger advantages than NTN cells, such as short propagation delay, good business continuity guarantee, etc., so terminal equipment is more inclined to be served by TN cells. For terminal equipment in the IDLE/INACTIVE state, priority should be given to reselecting/camping on the TN cell. However, it is discovered in time that there is a contradiction between the TN cell and terminal energy saving. For example, if the terminal device always turns on measurement, the TN cell can be discovered in time. However, usually because the coverage area of the NTN cell is much larger than that of the TN cell, it may be possible in most of the time/mobile range because the terminal device is not within the coverage of the TN cell. The TN cell signal cannot be detected.

This application provides a method for starting and stopping neighbor cell measurement in an NTN scenario. By introducing conditions such as distance range, angle range, and beam range, the terminal device can only start measurement of the corresponding frequency point/cell when it is close to the coverage of the target cell to be measured. This can achieve the purpose of saving terminal power.

Below, the technical solution of the present application will be introduced and explained through several embodiments.

Please refer to Figure 4, which shows a flow chart of a cell measurement method provided by an embodiment of the present application. This method can be applied to any communication system shown in FIGS. 1 to 3 , for example, the method can be executed by a terminal device. The method may include the following steps:

In some embodiments, the first object is a frequency point. For example, the first object is the first frequency point, and the first frequency point can be any frequency point. If the terminal device meets the coverage condition corresponding to the first frequency point, the terminal device starts or performs measurement on the first frequency point. Optionally, when the terminal device starts or performs measurement on the first frequency point, it means that the terminal device starts or performs measurement on the cell corresponding to the first frequency point. For example, the terminal device starts or performs measurement on all cells corresponding to the first frequency point. For example, the first frequency point corresponds to a cell, a is a positive integer, and the terminal device starts or performs measurement on the first frequency point, which means that the terminal device starts or performs measurement on a cells corresponding to the first frequency point.

In some embodiments, the first object includes multiple frequency points. For example, the first object is a frequency point list, frequency point set, or frequency point group, and the frequency point list, frequency point set, or frequency point group includes at least two frequency points. If the terminal device meets the coverage conditions corresponding to multiple frequency points, the terminal device starts or performs measurements on the multiple frequency points. Optionally, the terminal device initiating or performing measurements on the multiple frequency points means that the terminal device initiates or performs measurements on the cells corresponding to the multiple frequency points.

For example, the first object is a cell group, a cell list, or a cell set, and the cell group, cell list, or cell set includes at least two cells. If the terminal device meets the coverage conditions corresponding to multiple cells, the terminal device starts or performs measurements on the multiple cells. Optionally, the terminal device initiating or performing measurements on the multiple cells means that the terminal device initiates or performs measurements on all cells in the multiple cells. For example, the first object is a cell group, which includes cell 1 and cell 2. If the terminal device meets the coverage conditions corresponding to the cell group, the terminal device starts or performs measurements on cell 1 and cell 2.

In some embodiments, the first object includes one or more frequency points and one or more cells. At this time, if the terminal device meets the coverage conditions corresponding to the first object, the terminal device starts or performs measurements on the cells corresponding to each frequency point included in the first object and each cell included in the first object. For example, the first object includes a first frequency point and a second frequency point. The first frequency point corresponds to a cell, and the second frequency point corresponds to b cells. Both a and b are positive integers, and the first object also includes cell 1. and cell 2, then if the terminal device meets the coverage conditions corresponding to the first object, the terminal device starts or performs measurements on the a cells corresponding to the first frequency point and the b cells corresponding to the second frequency point, and performs measurements on cell 1 and cell 2. Cell 2 starts or performs measurements.

In some embodiments, when the terminal device starts measuring the first object, it means that the terminal device enters the unstarted state from the measurement of the first object to the started state, for example, the terminal device starts to perform the measurement of the first object. In some embodiments, the terminal device performing measurement on the first object means that the terminal device enters the executing state from the non-execution state for the measurement of the first object, for example, the terminal device executes a measurement process or behavior on the first object.

In some embodiments, the coverage condition corresponding to the first object is related to the serving cell of the terminal device, and the serving cell of the terminal device refers to the cell where the terminal device currently/is camping. In some embodiments, the coverage area of the serving cell of the terminal device is larger than the coverage area corresponding to the first object. For example, the coverage area corresponding to the first object is a partial area in the coverage area of the serving cell. In the case where the first object includes one or more frequency points, the coverage range corresponding to the first object includes the coverage range of all cells corresponding to the one or more frequency points. For example, it may include the coverage range corresponding to the one or more frequency points. The union area of coverage of all cells. In the case where the first object includes one or more cells, the coverage area corresponding to the first object includes the coverage area corresponding to the one or more cells. For example, it may include the union area of the coverage areas corresponding to the one or more cells. . In the case where the first object includes one or more frequency points and one or more cells, the coverage range corresponding to the first object includes the coverage range of all cells corresponding to the one or more frequency points and the one or more cells.

Wherein, the first object includes: one or more frequency points, and/or, one or more cells. The above coverage conditions are related to the serving cell of the terminal device. For details not explained in detail in this embodiment, such as explanations about the first object, coverage conditions, and whether the terminal device meets the coverage conditions, please refer to the introduction in the above embodiments, which will not be described again here.

In some embodiments, the measurement start condition is related to at least one of the following: a channel quality measurement result of the terminal device for the serving cell, a distance between the terminal device and a reference point of the serving cell, and time information of the terminal device. The channel quality measurement result of the terminal device for the serving cell may be one or a combination of one or more of the RSRP, RSRQ, SINR and other measurement results of the terminal device for the serving cell. The distance between the terminal device and the reference point of the serving cell may be the distance between the terminal device and the center point of the serving cell. The time information of the terminal device can be the departure time of the serving cell. The terminal device needs to start neighboring cell measurements on the same frequency, different frequencies, and different access technology frequencies before the departure time arrives, regardless of channel quality conditions and location (distance) conditions. Are you satisfied?

In some embodiments, if only the measurement start condition corresponding to the first object is set and the coverage condition corresponding to the first object is not set, then: if the serving cell of the first object and the terminal device correspond to the same frequency point, and/or , the reselection priority corresponding to the first object is lower than or equal to the reselection priority of the frequency point corresponding to the serving cell of the terminal device, then when the measurement start conditions are met, the terminal device starts or performs measurement on the first object; otherwise , if the measurement start condition is not met, the terminal device does not start or perform measurement on the first object. In addition, if the reselection priority corresponding to the first object is higher than the reselection priority of the frequency point corresponding to the serving cell of the terminal device, the terminal device starts or performs measurement on the first object, regardless of whether the measurement start condition is met.

For example, the measurement start conditions include: the channel quality measurement result (such as RSRP/RSRQ measurement value) of the terminal device for the serving cell is less than or equal to a certain measurement value threshold, or the distance between the terminal device and the reference point of the serving cell is greater than or equal to equal to a certain distance threshold. If the terminal device supports location-based neighbor cell measurement control and has valid location information, then when the terminal device meets the above measurement startup conditions, the terminal device starts or performs measurements on different frequency points such as the same frequency, the same priority, and low priority. Neighbor cell measurement; On the contrary, if the terminal equipment does not meet the above measurement start conditions (that is, when the channel quality measurement result of the serving cell (such as RSRP/RSRQ measurement value) is greater than the above measurement value threshold, and the reference point between the terminal equipment and the serving cell When the distance is less than the above distance threshold), the terminal device may not start or perform (such as stopping) neighbor cell measurements on the same frequency, same priority, low priority and other different frequency points. Furthermore, you can consider introducing time information. Network equipment can broadcast a serving cell departure time. The terminal equipment needs to start neighbor cell measurements on the same frequency, different frequencies, and different access technology frequencies before the departure time arrives, regardless of RSRSP/RSRQ. Whether the condition and location (distance) conditions are met. For high-priority frequencies, the terminal device always measures, regardless of the remaining service time of the serving cell.

In some embodiments, in addition to setting the measurement start condition corresponding to the first object, the coverage condition corresponding to the first object is also set, then: if the first object and the serving cell of the terminal device correspond to the same frequency point, and/ Or, the reselection priority corresponding to the first object is lower than or equal to the reselection priority of the frequency point corresponding to the serving cell of the terminal device, then when the measurement startup conditions are met and the coverage conditions are met, the terminal device starts the first object Or perform measurement; otherwise, if the measurement start condition and/or the coverage condition is not met, the terminal device does not start or perform measurement on the first object. In addition, if the reselection priority corresponding to the first object is higher than the reselection priority of the frequency point corresponding to the serving cell of the terminal device, then if the coverage conditions are met, the terminal device starts or performs measurement on the first object; otherwise, If the coverage condition is not met, the terminal device does not start or perform measurement on the first object.

Through the above method, the two aspects of measurement start condition and coverage condition are combined to control the start and stop of neighbor cell measurement, thereby achieving better terminal power saving.

In addition, the above-mentioned reselection priority can be expressed by a priority value. If the larger the priority value, the higher the reselection priority. Then the reselection priority corresponding to the first object is lower than or equal to the reselection priority of the frequency point corresponding to the serving cell of the terminal device. It refers to the reselection priority corresponding to the first object. The reselection priority value is less than or equal to the reselection priority value of the frequency point corresponding to the serving cell of the terminal device; the reselection priority corresponding to the first object is higher than the reselection priority value of the frequency point corresponding to the serving cell of the terminal device, which refers to the reselection priority value of the frequency point corresponding to the serving cell of the terminal device. The reselection priority value corresponding to an object is greater than the reselection priority value corresponding to the frequency point of the serving cell of the terminal device. If the smaller the priority value is, the higher the reselection priority is. Then the reselection priority corresponding to the first object is lower than or equal to the reselection priority corresponding to the frequency point of the serving cell of the terminal device. It refers to the reselection priority corresponding to the first object. The reselection priority value is greater than or equal to the reselection priority value of the frequency point corresponding to the serving cell of the terminal device; the reselection priority value corresponding to the first object is higher than the reselection priority value of the frequency point corresponding to the serving cell of the terminal device, which refers to the reselection priority value of the corresponding frequency point of the serving cell of the terminal device. The reselection priority value corresponding to an object is smaller than the reselection priority value corresponding to the frequency point of the serving cell of the terminal device. The embodiment of the present application does not limit the expression method of the reselection priority.

In some embodiments, the serving cell of the terminal device is an NTN cell, and the cell corresponding to the first object is a TN cell.

In some embodiments, the frequency point corresponding to the first object is a TN dedicated frequency point, and the TN dedicated frequency point refers to a frequency point where NTN cells are not deployed. That is to say, the cell measurement method provided in the above embodiment is only used for measurement startup or execution on TN dedicated frequency points, but not for mixed deployment scenarios (that is, TN cells and NTN are deployed simultaneously on the frequency point corresponding to the first object). community).

In some embodiments, the TN dedicated frequency point is indicated using an explicit indication method. When the TN dedicated frequency point adopts the explicit indication method, the terminal device determines whether the target frequency point is a TN dedicated frequency point based on the explicit indication information corresponding to the target frequency point contained in the system message. For example, the explicit indication information corresponding to the target frequency point is used to directly or explicitly indicate that the target frequency point is a TN dedicated frequency point or not a TN dedicated frequency point. The explicit indication information can be represented by 1 bit, for example, 1 indicates that it is a TN dedicated frequency point and 0 indicates that it is not a TN dedicated frequency point, or 0 indicates that it is a TN dedicated frequency point and 1 indicates that it is not a TN dedicated frequency point. Or, if the system message contains explicit indication information corresponding to the target frequency point, the terminal device determines that the target frequency point is a TN dedicated frequency point; conversely, if the system message does not contain explicit indication information corresponding to the target frequency point, then The terminal equipment determines that the target frequency point is not a TN dedicated frequency point.

In some embodiments, the TN dedicated frequency point is indicated using an implicit indication method. If the implicit indication method is used, the terminal device can determine whether the target frequency point is a TN dedicated frequency point based on whether the ephemeris information related to neighboring cells is configured for the target frequency point in the system message. For example, when the TN dedicated frequency point adopts the implicit indication method, if the ephemeris information related to the neighboring cell is not configured for the target frequency point in the system message, the terminal device determines that the target frequency point is the TN dedicated frequency point; conversely, if If the ephemeris information related to neighboring cells is configured for the target frequency point in the system message, the terminal device determines that the target frequency point is not a TN dedicated frequency point.

Through the above method, this method is only used for measurement startup or execution for TN dedicated frequency points, but not for mixed deployment scenarios. This is because the coverage area of TN cells is much smaller than the coverage area of NTN cells. Therefore, this application The technical solution is particularly suitable for this scenario, in which a more obvious terminal energy saving effect can be achieved.
