In a communication system, in general, a terminal device completes handover from a current serving base station to another base station through a measurement reporting mechanism, where the measurement reporting mechanism of the terminal device is a precondition that a source base station selects an appropriate target base station for the terminal device, the terminal device measures signal quality of a neighboring base station when a measurement trigger condition is satisfied according to measurement configuration of a network side, and reports the signal quality to the source base station in a measurement report form, and the source base station selects one or several appropriate target base stations for the terminal device according to the measurement report reported by the terminal device, and initiates a handover request procedure.

For the cell reselection process, the terminal determines a measurement target according to the system information broadcasted by the serving cell and the effective special frequency point priority information, measures the signal quality of the neighbor cell base station when the measurement trigger condition is met, and initiates a cell reselection process once the reselection condition is met.

For example, LEO satellites typically have an orbital altitude ranging from 500km to 1500km, and an orbital period (period of rotation around the earth) ranging from about 1.5 hours to 2 hours. The maximum satellite visibility time, which is the maximum time that the satellite beam covers a certain area of the ground, is about 20 minutes, and the LEO satellite is moving relative to the ground, and the area of the ground that it covers varies as the satellite moves. The LEO satellite has short signal propagation distance, less link loss and low requirement on the transmitting power of terminal equipment. The orbit height of GEO satellites is typically 35786km with an orbit period of 24 hours. To ensure coverage of the satellites and to increase the system capacity of the communication network, the satellites may cover the ground with multiple beams, for example, one satellite may form tens or hundreds of beams to cover the ground, and one beam may cover a ground area with a diameter of tens to hundreds of kilometers.

In the terrestrial communication system shown in fig. 1, after the service performance and communication quality of the terminal device are degraded, it is generally necessary to switch the terminal device from one cell to another cell or reselect from one cell to another, for example, from 1 to 2 in fig. 1 or from 1 to 2. In general, a terminal device needs to complete handover from a current serving base station to another base station through a measurement reporting mechanism, where the measurement reporting mechanism of the terminal device is a precondition that a source base station selects a suitable target base station for the terminal device, the terminal device measures signal quality of a neighboring base station when a measurement trigger condition is met according to measurement configuration of a network side, and reports the signal quality to the source base station in a measurement report form, and the source base station selects one or several suitable target base stations for the terminal device according to the measurement report reported by the terminal device, and initiates a handover request process.

In the satellite communication system shown in fig. 2, satellite handoff includes a variety of scenarios: (1) Switching among cells in the same satellite in the same gateway station; (2) Switching among cells among different satellites in the same gateway station; (3) Switching among cells among different satellites in different gateway stations; (4) Handoff between cells within the same satellite occurs within different gateway stations. Taking scenario 2 as an example, when the terminal device is about to be separated from the satellite 21 signal, the network side device triggers the terminal device to switch from the satellite 21 to the satellite 22, wherein if the satellite is a transparent forwarding satellite or a regenerated satellite with only a Distributed Unit (DU) on the satellite, the switching process is triggered by the gateway station, and if the satellite is a regenerated satellite with a Centralized Unit (CU) on the satellite, the switching process is triggered by the satellite itself, so it can be seen that the angle at which the terminal device receives different satellite signals is different.

In the satellite communication system, the process of cell reselection by the terminal device is similar to the process of cell handover, and the process of cell reselection is not described herein.

However, in a communication system, a high frequency band is sometimes used. Particularly, in satellite communication systems, the frequency spectrum used is wider, from several GHz to several tens GHz, and if a high frequency band such as Ka band is used, the volatility is poor compared with a low frequency band due to the shorter wavelength of the high frequency electromagnetic wave, so that the terminal device generally chooses to use a directional antenna to obtain additional antenna gain. For a terminal device using a directional antenna, since the directional antenna has strong directivity, in order to find a target satellite or a target cell, the terminal device may need to spend a lot of time searching for a target cell in several candidate cells or searching for a target satellite if it follows the above measurement or handover procedure. However, typically, the speed of a LEO satellite sweeping across the ground may reach several kilometers/second, which is a few seconds that can provide signal service to the terminal device, and if the terminal device consumes a lot of time to search for the target cell or the target satellite, this may cause a larger delay in the handoff procedure or the cell reselection procedure. If the terminal equipment cannot find the target cell or the target satellite in time to initiate the access process, the terminal equipment may have a risk of off-line, thereby reducing the continuous performance experience of the terminal equipment service. It is therefore important for terminal devices using directional antennas how the target satellite or target cell direction can be determined in time.

In view of the foregoing problems, a communication method is provided in this embodiment, where a network side device generates a first message, and sends the first message to a terminal device, where the first message includes target auxiliary information, where the target auxiliary information is used to indicate identification information of a network node, where the network node includes a target satellite or a target cell, and the terminal device adjusts an antenna angle according to the received target auxiliary information, and then measures a signal of the network node or adjusts an antenna angle and then switches to the network node. Because the network side equipment can send the identification information of the network node to the terminal equipment, the process that the terminal equipment uses the directional antenna to carry out blind trial can be avoided, the terminal equipment can directly carry out signal measurement on the network node corresponding to the identification information according to the identification information sent by the network side equipment after adjusting the angle of the antenna, or switch to the network node after adjusting the angle of the antenna, thereby reducing the time delay of the terminal equipment in the switching process or the cell reselection process, reducing the risk of the terminal equipment off-line, and further improving the continuous performance experience of the terminal equipment service.

The technical scheme of the communication method provided by the application is described in detail below through detailed embodiments. It is to be understood that the following embodiments may be combined with each other and that some embodiments may not be repeated for the same or similar concepts or processes.

Fig. 3 is a signaling diagram of a communication method provided in an embodiment of the present application, and it should be noted that, although in an embodiment of the present application, the steps of the method are presented in a specific order, the order of the steps may be changed in different embodiments, and in some embodiments, one or more steps shown in the order in the present specification may be performed simultaneously. As shown in fig. 3, the method includes:

step 301: the network side equipment generates a first message, wherein the first message comprises target auxiliary information, the target auxiliary information is used for representing identification information of a network node, and the network node comprises a target satellite or a target cell.

In the ground communication system, the network-side device may be understood as a base station. In a satellite communication system, if a satellite only performs signal amplification and radio frequency conversion, the network side device can be understood as a base station, and after generating a first message, the base station sends the generated first message to the satellite, and forwards the generated first message to a terminal device after performing signal amplification and radio frequency conversion processing through the satellite. If the satellite is a regenerated satellite, the network-side device may be understood as the regenerated satellite.

The first message may be included in a cell broadcast message or higher layer dedicated signaling, for example. In one possible implementation, the first message may be a higher layer dedicated signaling for a terminal device in a connected state and a cell broadcast message, such as a system information block (System Information Block, SIB), for a terminal device in an idle state.

The higher layer dedicated signaling may refer to signaling sent by a higher layer protocol layer, where the higher layer protocol layer is at least one protocol layer above a physical layer. The higher protocol layer may specifically include at least one of the following protocol layers: the medium access control (medium access control, MAC) layer, radio link control (radio link control, RLC) layer, packet data convergence protocol (packet data convergence protocol, PDCP) layer, radio resource control (radio resource control, RRC) layer, non-access stratum (NAS) layer, etc., then the higher layer signaling may include RRC signaling, MAC Control Element (CE), etc.

In addition, the target assistance information may be used to represent identification information of a network node, including a target satellite or a target cell. The target satellite is a satellite which needs to be measured or switched by the terminal equipment, and the target cell is a cell which needs to be measured or switched by the terminal equipment.

In one possible implementation, when the network node includes a target satellite, the target assistance information may include at least one of the following information: satellite identification information associated with satellite operation data of the target satellite, orbit identification information associated with satellite operation data of the target satellite, or index information corresponding to satellite operation data of the target satellite.

In particular, the above satellite operation data can be understood as an Ephemeris map (ephemerides) in the satellite domain. The initial position state vector information of the satellite at a certain defined time starting point can be obtained through the ephemeris, the time starting point information is common in general, the satellite is not independently bound with a certain satellite, and 6 parameters are needed to represent one satellite operation data, wherein the absolute space position of the satellite needs to be represented by three parameters, and the space velocity vector of the satellite needs to be represented by three parameters. Therefore, according to the meaning of the ephemeris, after the satellite operation data of a certain satellite is obtained, the spatial position information of the satellite at any time point in the future can be accurately calculated.

The satellite operation data may be provided by a non-access layer or by an access layer.

For example, the satellite operation data may be associated with the satellite identification information by using the explicit indexing method in table 1, or may be understood as establishing a correspondence between the satellite operation data and the satellite identification information, where the satellite operation data in table 1 has a one-to-one correspondence with the satellite identification information.

TABLE 1

The target auxiliary information includes satellite identification information associated with satellite operation data of the target satellite, and the satellite operation data corresponding to the satellite identification information can be obtained from the satellite identification information by the index relationship in table 1. For example: if the target auxiliary information includes satellite identification information 2, satellite operation data 2 corresponding to the satellite identification information 2 can be determined according to table 1.

For example, the satellite operation data may be associated with the orbit identification information of the satellite by the explicit indexing method in table 2, or it may be understood that a correspondence relationship is established between the satellite operation data and the orbit identification information of the satellite. The satellite operation data in table 2 has a one-to-one correspondence with the orbit identification information of the satellite.

TABLE 2

When the target auxiliary information includes orbit identification information associated with the satellite operation data of the target satellite, the satellite operation data corresponding to the orbit identification information can be obtained from the orbit identification information by the index relationship in table 2. For example: if the orbit identification information M-1 is included in the target auxiliary information, the satellite operation data M-1 corresponding to the satellite identification information M-1 can be determined according to table 2.

By way of example, it is also possible to form a list of all the satellite operation data, and associate each satellite operation data with index (index) information of the satellite operation data in the list in the manner shown in table 3, or understand that a correspondence is established between the satellite operation data and the index information. The satellite operation data in table 3 has a one-to-one correspondence with the index information.

TABLE 3 Table 3

It should be understood that index information 1 indicates that the index value of satellite operation data 1 in the list formed by all the satellite operation data is 1.

When the target auxiliary information includes index information corresponding to the satellite operation data of the target satellite, the satellite operation data corresponding to the index information can be obtained according to the index information by the corresponding relation in table 3. For example: if the target auxiliary information includes index information 1, satellite operation data 1 corresponding to the index information 1 can be determined according to table 3.

Wherein M in tables 1 to 3 is a positive integer of 1 or more.

It is understood that the target auxiliary information may include only satellite identification information, orbit identification information, or index information, or may include two or more of the above information at the same time, for example, the target auxiliary information may include both satellite identification information and orbit identification information at the same time.

Through the correspondence relationships shown in the above tables 1 to 3, the terminal device can determine the satellite operation data of the target satellite after receiving the target auxiliary information, so as to calculate the spatial position information of the target satellite at any future time point.

In this embodiment, since the data size of the satellite operation data is large, one or more of satellite identification information associated with the satellite operation data of the target satellite, orbit identification information associated with the satellite operation data of the target satellite, and index information corresponding to the satellite operation data of the target satellite may be set in the target auxiliary information, and the target satellite may be represented by the above information, so as to avoid a phenomenon in which the satellite operation data is directly embedded into the measurement configuration or the handover configuration and transmitted to the terminal device, so that the transmission size of the data may be reduced, and communication resources may be saved.

In another possible implementation, when the network node comprises a target cell, the target assistance information comprises geographical location information and/or position information of the target cell signal source.

Specifically, the geographic location information may be latitude and longitude information, and the azimuth information may be direction information. In the ground communication system, the target auxiliary information may include only the geographical position information of the signal source of the target cell to be measured or switched, may include only the azimuth information of the signal source of the target cell to be measured or switched, and may include the geographical position information and the azimuth information of the signal source of the target cell to be measured or switched. In this way, after the network side device sends the target auxiliary information to the terminal device, the terminal device can determine the position or direction of the target cell according to the geographic position information and/or the azimuth information.

In this embodiment, the geographical location information and/or the azimuth information of the signal source of the target cell are set in the target auxiliary information to inform the terminal device of the location or the direction of the target cell, so that the phenomenon that the terminal device searches the target cell first and then measures the target cell or switches to the target cell can be avoided, and the time delay of measuring or switching to the target cell can be reduced.

Step 302: the network side equipment sends a first message to the terminal equipment.

In this step, after the network side device generates the first message, the first message is sent to the terminal device.

Step 303: and the terminal equipment measures signals of the network node after adjusting the antenna angle or switches to the network node after adjusting the antenna angle according to the target auxiliary information.

In this step, when the network node includes the target satellite, the terminal device may determine the spatial location information of the target satellite according to the target auxiliary information, and adjust the receiving antenna angle of the terminal device, so that the receiving antenna of the terminal device is aligned with the signal sent by the target satellite, thereby measuring the signal of the target satellite, or switch to the target satellite.

For the manner of adjusting the antenna angle according to the target auxiliary information, in one possible implementation manner, the satellite operation data of the target satellite associated with the measurement frequency point may be determined according to the target auxiliary information, a first association relationship and a second association relationship, where the first association relationship is used to represent the association relationship between the measurement frequency point and the target auxiliary information, and the second association relationship is used to represent the association relationship between the auxiliary information and the satellite operation data, and then the antenna angle is adjusted according to the satellite operation data of the target satellite and the geographic position information of the terminal device.

Specifically, the second association relationship may be pre-stored in the terminal device or acquired through network side system information or dedicated signaling, where the association relationship is used to represent a correspondence relationship between the plurality of auxiliary information and the plurality of satellite operation data, and the auxiliary information and the satellite operation data have a one-to-one correspondence relationship. For example: the assistance information 1 corresponds to the satellite operation data 1, the assistance information 2 corresponds to the satellite operation data 2, … … and the assistance information P corresponds to the satellite operation data P.

The first association relationship may be included in the first message, where the first association relationship is used to represent an association relationship between the measurement frequency point and target auxiliary information, and the target auxiliary information is any one of a plurality of auxiliary information in the second association relationship. The first association relationship may be as shown in table 4:

TABLE 4 Table 4

Wherein N in table 4 is a positive integer greater than or equal to 1.

Illustratively, a measurement object (measurement object, MO) contains a measurement frequency bin, and a measurement frequency bin information is in turn associated with a target auxiliary information. Namely, there is a one-to-one correspondence between the measurement object, the measurement frequency point, and the target auxiliary information.

The measurement frequency points may be satellite frequency points or synchronization signals and physical broadcast channel (physical broadcast channel, PBCH) blocks (synchronization signaland PBCHblock, SSB) or channel state information reference signals (channel state information-reference signals, CSI-RS) or cell frequency points.

Since after receiving the target auxiliary information, the satellite operation data corresponding to the target auxiliary information can be determined according to the second association relationship, and then the satellite operation data of the target satellite associated with the measurement frequency point can be determined according to the first association relationship as shown in table 4, the terminal device can adjust its own receiving antenna angle according to the satellite operation data of the target satellite and the geographic position information of the terminal device, so that the receiving antenna of the terminal device aims at the signal sent by the target satellite, and then the signal of the target satellite is measured according to the measurement frequency point.

For example, according to the target auxiliary information, the first association relationship and the second association relationship, the determined satellite operation data of the target satellite associated with the measurement frequency point may be as shown in table 5:

TABLE 5

Wherein N in table 5 is a positive integer greater than or equal to 1.

For example, if the first message includes the target auxiliary information 1, the terminal device may determine the satellite operation data 1 corresponding to the target auxiliary information 1 according to the second association relationship, and then determine the satellite operation data 1 of the target satellite associated with the measurement frequency point 1 according to the first association relationship. In this way, the terminal device adjusts its own receiving antenna according to the satellite operation data 1 of the target satellite and the geographic position information of the terminal device, and then measures the signal of the target satellite according to the measurement frequency point 1.

In this embodiment, after determining the satellite operation data of the target satellite associated with the measurement frequency point, the terminal device may adjust the antenna angle according to the satellite operation data and the geographic location information of the terminal device, and then measure the signal of the target satellite according to the measurement frequency point, so that the efficiency of directional antenna signal measurement may be improved.

In another possible implementation manner, according to the target auxiliary information, the third association relationship and the second association relationship, determining satellite operation data of a target satellite associated with a target physical cell identifier (physical cell identifier, PCI) configured on the measurement frequency point, where the target PCI is any one of a plurality of PCIs configured on the measurement frequency point, the third association relationship is used to represent the association relationship between the PCI configured on the measurement frequency point and the target auxiliary information, and then according to the satellite operation data and geographic position information of the terminal device, adjusting an antenna angle, and measuring a signal of the target satellite.

Specifically, a third association relationship may be included in the first message, where the third association relationship is used to represent an association relationship between the PCI configured on the measurement frequency point and the target auxiliary information. The third association relationship may be as shown in table 6:

TABLE 6

Wherein, P, Q, N, X and Y in table 6 are positive integers of 1 or more.

Illustratively, a measurement object (measurement object, MO) contains a measurement frequency point, and a measurement frequency point information is in turn associated with one or more PCI information, and a PCI is in turn associated with a target auxiliary information.

The measurement frequency points may be satellite frequency points, SSBs, CSI-RS or cell frequency points.

After receiving the target auxiliary information, the satellite operation data corresponding to the target auxiliary information can be determined according to the second association relation, then the satellite operation data of the target satellite associated with the target PCI configured on the measurement frequency point can be determined according to the third association relation shown in table 6, so that the terminal equipment can adjust the angle of the receiving antenna of the terminal equipment according to the satellite operation data of the target satellite and the geographic position information of the terminal equipment, the receiving antenna of the terminal equipment aims at the signal sent by the target satellite, and then the signal of the target satellite is measured according to the target PCI configured on the measurement frequency point.

For example, according to the target auxiliary information, the third association relationship and the second association relationship, the satellite operation data of the target satellite associated with the target PCI configured on the determined measurement frequency point may be as shown in table 7:

TABLE 7

Wherein, P, Q, N, X and Y in table 7 are positive integers of 1 or more.

For example, if the first message includes the target auxiliary information 11, the terminal device may determine the satellite operation data 1 corresponding to the target auxiliary information 11 according to the second association relationship, and then determine the satellite operation data 1 of the target satellite associated with the target PCI 11 configured on the measurement frequency point 1 according to the third association relationship. In this way, the terminal device will adjust its own receiving antenna according to the satellite operation data 1 of the target satellite and the geographical position information of the terminal device, and then measure the signal of the target satellite according to the measurement frequency point 1 and the target PCI 11 configured thereon.

It can be appreciated that, since the measurement is performed on the target satellite, the measurement frequency point and the PCI need to be determined at the same time. For the association relationship shown in table 5, when the target satellite is measured, a maximum of 1008 kinds of PCI information need to be blindly tried for each measurement frequency point, and then the target PCI can be determined. For the association relationship shown in table 7, the network side device configures the target PCI in the target auxiliary information, and the terminal device does not need to determine the PCI information associated with the measurement frequency point through a blind try process. The space scanning process of the directional antenna is independent of the measurement frequency point and the PCI determining process, and the target auxiliary information configured on the network side is only associated with the measurement frequency point or is simultaneously associated with the measurement frequency point and the PCI information, so that the efficiency of measuring the directional antenna signal of the terminal can be improved.

In this embodiment, after determining the satellite operation data of the target satellite associated with the target PCI configured on the measurement frequency point, the terminal device may adjust the antenna angle according to the satellite operation data and the geographic location information of the terminal device, and then measure the signal of the target satellite according to the measurement frequency point and the target PCI, so that the efficiency of directional antenna signal measurement may be improved.

In addition, when switching to the target satellite, the antenna angle of the terminal device needs to be adjusted first, in one possible implementation manner, the satellite operation data of the target satellite associated with the switching configuration information may be determined according to the target auxiliary information, a fifth association relationship and a second association relationship, where the fifth association relationship is used to represent the association relationship between the switching configuration information and the target auxiliary information, and the second association relationship is used to represent the association relationship between the auxiliary information and the satellite operation data, and then the antenna angle is adjusted according to the satellite operation data of the target satellite and the geographic position information of the terminal device.

Specifically, the second association relationship may be pre-stored in the terminal device, the association relationship being used to represent a correspondence relationship between the plurality of auxiliary information and the plurality of satellite operation data, and the auxiliary information and the satellite operation data having a one-to-one correspondence relationship therebetween. For example: the assistance information 1 corresponds to the satellite operation data 1, the assistance information 2 corresponds to the satellite operation data 2, … … and the assistance information P corresponds to the satellite operation data P.

The fifth association may be included in the first message, where the fifth association is used to represent an association between handover configuration information and target auxiliary information, where the handover configuration information may be understood as handover candidate cell configuration information and may also be understood as synchronous reconfiguration configuration information, and the target auxiliary information is any one of the plurality of auxiliary information in the second association. The fifth association relationship may be as shown in table 8:

TABLE 8

First message
	Handover configuration information
Target assistance information

The first message includes a set of handover configuration information, and the set of handover configuration information is associated with a target auxiliary information.

After receiving the target auxiliary information, the satellite operation data corresponding to the target auxiliary information can be determined according to the second association relation, and then the satellite operation data of the target satellite associated with the switching configuration information can be determined according to the fifth association relation shown in table 8, so that the terminal equipment can adjust the angles of the transmitting and receiving antennas of the terminal equipment according to the satellite operation data of the target satellite and the geographic position information of the terminal equipment, and the transmitting and receiving antennas of the terminal equipment are aligned to the target satellite, so that the terminal equipment can be switched to the target satellite according to the switching configuration information.

For example, if the first message includes the target auxiliary information 1, the terminal device may determine the satellite operation data 1 corresponding to the target auxiliary information 1 according to the second association relationship, and may determine the satellite operation data 1 of the target satellite associated with the handover configuration information according to the fifth association relationship. In this way, the terminal device adjusts its own transmitting and receiving antenna according to the satellite operation data 1 of the target satellite and the geographic position information of the terminal device, and then switches to the target satellite according to the switching configuration information.

In this embodiment, after determining the satellite operation data of the target satellite associated with the switching configuration information, the terminal device may adjust the antenna angle according to the satellite operation data and the geographic location information of the terminal device, and then switch to the target satellite according to the switching configuration information, so that the efficiency of the switching process may be improved.

In another possible implementation manner, satellite operation data of a target satellite associated with configuration information of a candidate cell in the handover configuration information is determined according to the target auxiliary information, a sixth association relationship and a second association relationship, where the sixth association relationship is used to represent an association relationship between the configuration information of the candidate cell in the handover configuration information and the target auxiliary information, and an antenna angle is adjusted according to the satellite operation data of the target satellite and geographic position information of the terminal device.

Specifically, the sixth association relationship may be included in the first message, where the sixth association relationship is used to represent an association relationship between configuration information of the candidate cell and the target auxiliary information in the handover configuration information, and the handover configuration information may be understood as handover candidate cell configuration information and may also be understood as synchronous reconfiguration configuration information. The sixth association relationship may be as shown in table 9:

TABLE 9

The first message includes one or more sets of switching configuration information, and each set of switching configuration information is associated with one target auxiliary information.

Since after receiving the target auxiliary information, satellite operation data corresponding to the target auxiliary information may be determined according to the second association relationship, and then satellite operation data of the target satellite associated with the configuration information of the candidate cell in the handover configuration information may be determined according to the sixth association relationship as shown in table 9. In this way, the terminal device can adjust the angles of the transmitting and receiving antennas of the terminal device according to the satellite operation data of the target satellite and the geographic position information of the terminal device, so that the transmitting and receiving antennas of the terminal device aim at the target satellite, and the terminal device can switch to the target satellite according to the configuration information of the candidate cell in the switching configuration information.

For example, if the first message includes the target auxiliary information 1, the terminal device may determine the satellite operation data 1 corresponding to the target auxiliary information 1 according to the second association relationship, and may determine the satellite operation data 1 of the target satellite associated with the handover configuration information 1 according to the sixth association relationship. In this way, the terminal device adjusts its own transmitting and receiving antenna according to the satellite operation data 1 of the target satellite and the geographic position information of the terminal device, and then switches to the target satellite according to the switching configuration information 1.

In this embodiment, after determining the satellite operation data associated with the configuration information of the candidate cell in the handover configuration information, the terminal device may adjust the antenna angle according to the satellite operation data and the geographic location information of the terminal device, and then switch to the target satellite according to the configuration information of the candidate cell in the handover configuration information, so that the efficiency of the handover procedure may be improved.

For example, when the network node includes the target cell, the terminal device may determine the location information or the direction information of the target cell according to the target auxiliary information, and adjust the antenna angle of the terminal device to align the antenna of the terminal device with the signal sent by the target cell, thereby measuring the signal of the target cell, or switch to the target cell.

For the manner of adjusting the antenna angle according to the target auxiliary information, in one possible implementation manner, the geographic position information and/or the azimuth information of the target cell associated with the measurement frequency point may be determined according to the target auxiliary information, a first association relationship and a fourth association relationship, where the first association relationship is used to represent the association relationship between the measurement frequency point and the target auxiliary information, and the fourth association relationship is used to represent the association relationship between the auxiliary information and the geographic position information and/or the azimuth information, and then the antenna angle is adjusted according to the geographic position information and/or the azimuth information of the target cell and the geographic position information of the terminal device.

Specifically, the fourth association relationship may be pre-stored in the terminal device or obtained through network side system information or dedicated signaling, where the association relationship is used to represent a correspondence relationship between the plurality of auxiliary information and the plurality of geographic location information and/or azimuth information, and the auxiliary information has a one-to-one correspondence relationship with the geographic location information and/or the azimuth information. For example: the assistance information 1 corresponds to the geographical position information 1 and/or the azimuth information 1, the assistance information 2 corresponds to the geographical position information 2 and/or the azimuth information 2, and the assistance information P corresponds to the geographical position information P and/or the azimuth information P … ….

The first association relationship may be included in the first message, where the first association relationship is used to represent an association relationship between the measurement frequency point and target auxiliary information, and the target auxiliary information is any one of a plurality of auxiliary information in the fourth association relationship. The first association relationship may be as shown in table 4.

After receiving the target auxiliary information, the geographic position information and/or azimuth information corresponding to the target auxiliary information can be determined according to the fourth association relation, then the geographic position information and/or azimuth information of the target cell signal source associated with the measurement frequency point can be determined according to the first association relation shown in table 4, so that the terminal equipment can adjust the angle of the receiving antenna of the terminal equipment according to the geographic position information and/or azimuth information of the target cell signal source and the geographic position information of the terminal equipment, the receiving antenna of the terminal equipment aims at the signal sent by the target cell, and then the signal of the target cell is measured according to the measurement frequency point.

For example, if the first message includes the target auxiliary information 1, the terminal device may determine the geographic location information 1 and/or the azimuth information 1 corresponding to the target auxiliary information 1 according to the fourth association relationship, and may determine the geographic location information 1 and/or the azimuth information 1 associated with the measurement frequency point 1 of the measurement object 1 according to the first association relationship. In this way, the terminal device adjusts its own receiving antenna according to the geographical position information 1 and/or the azimuth information 1 and the geographical position information of the terminal device, and then measures the signal of the target cell according to the measurement frequency point 1.

In this embodiment, after determining the geographical location information and/or the azimuth information of the target cell signal source associated with the measurement frequency point, the terminal device may adjust the antenna angle according to the geographical location information and/or the azimuth information of the target cell signal source and the geographical location information of the terminal device, and then measure the signal of the target cell according to the measurement frequency point, so as to improve the efficiency of directional antenna signal measurement.

In another possible implementation manner, geographic location information and/or azimuth information of a target cell associated with a target PCI configured on a measurement frequency point may be determined according to the target auxiliary information, a third association relationship and the fourth association relationship, where the target PCI is any one of a plurality of PCIs configured on the measurement frequency point, and the third association relationship is used to represent an association relationship between the PCI configured on the measurement frequency point and the target auxiliary information, and adjust an antenna angle according to the geographic location information and/or azimuth information of the target cell and the geographic location information of the terminal device.

Specifically, a third association relationship may be included in the first message, where the third association relationship is used to represent an association relationship between the PCI configured on the measurement frequency point and the target auxiliary information.

Since after the target auxiliary information is received, the geographic position information and/or the azimuth information corresponding to the target auxiliary information can be determined according to the fourth association relationship, and then the geographic position information and/or the azimuth information of the target cell signal source associated with the target PCI configured on the measurement frequency point can be determined according to the third association relationship as shown in table 6. In this way, the terminal device can adjust its own receiving antenna angle according to the geographical position information and/or azimuth information of the signal source of the target cell and the geographical position information of the terminal device, so that the receiving antenna of the terminal device is aligned to the signal sent by the target cell, and then the signal of the target cell is measured according to the measurement frequency point and the target PCI configured on the measurement frequency point.

For example, if the first message includes the target auxiliary information 11, the terminal device may determine the geographic location information 1 and/or the azimuth information 1 corresponding to the target auxiliary information 1 according to the fourth association relationship, and may determine the geographic location information 1 and/or the azimuth information 1 associated with the target PCI11 configured on the measurement frequency point 1 of the measurement object 1 according to the third association relationship. In this way, the terminal device can adjust its own receiving antenna according to the geographical location information 1 and/or the azimuth information 1 and the geographical location information of the terminal device, and then measure the signal of the target cell according to the measurement frequency point 1 and the PCI11 information.

In this embodiment, after determining the geographical location information and/or the azimuth information of the target cell signal source associated with the target PCI configured on the measurement frequency point, the terminal device may adjust the antenna angle according to the geographical location information and/or the azimuth information of the target cell signal source and the geographical location information of the terminal device, and then measure the signal of the target cell according to the measurement frequency point and the target PCI configured thereon, so as to improve the efficiency of directional antenna signal measurement.

In addition, when switching to the target cell, it is also necessary to first adjust the antenna angle of the terminal device. In one possible implementation manner, the geographic position information and/or the azimuth information of the target cell associated with the handover configuration information may be determined according to the target auxiliary information, a fifth association relationship and a fourth association relationship, where the fifth association relationship is used to represent the association relationship between the handover configuration information and the target auxiliary information, and the fourth association relationship is used to represent the association relationship between the auxiliary information and the geographic position information and/or the azimuth information, and then the antenna angle is adjusted according to the geographic position information and/or the azimuth information of the target cell and the geographic position information of the terminal device.

The fifth association relationship may be included in the first message, where the fifth association relationship is used to represent an association relationship between handover configuration information and target auxiliary information, where the handover configuration information may be understood as handover candidate cell configuration information and may also be understood as synchronous reconfiguration configuration information. The target auxiliary information is any one of a plurality of auxiliary information in the second association relation.

Since after receiving the target auxiliary information, the geographic position information and/or the azimuth information of the target cell signal source corresponding to the target auxiliary information can be determined according to the fourth association relationship, and then the geographic position information and/or the azimuth information of the target cell signal source associated with the handover configuration information can be determined according to the fifth association relationship as shown in table 8. In this way, the terminal device can adjust the angles of the transmitting and receiving antennas of the terminal device according to the geographic position information and/or azimuth information of the signal source of the target cell and the geographic position information of the terminal device, so that the transmitting and receiving antennas of the terminal device aim at the signal transmitted by the target cell, and the terminal device is switched to the target cell according to the switching configuration information.

For example, if the first message includes the target auxiliary information 1, the terminal device may determine the geographic location information 1 and/or the azimuth information 1 of the target cell signal source corresponding to the target auxiliary information 1 according to the fourth association relationship, and may determine the geographic location information and/or the azimuth information of the target cell signal source associated with the handover configuration information according to the fifth association relationship. In this way, the terminal device adjusts its own transmitting and receiving antenna according to the geographical position information and/or azimuth information of the signal source of the target cell and the geographical position information of the terminal device, and then switches to the target cell according to the switching configuration information.

In this embodiment, after determining the geographical location information and/or the azimuth information of the target cell signal source associated with the handover configuration information, the terminal device may adjust the antenna angle according to the geographical location information and/or the azimuth information and the geographical location information of the terminal device, and then switch to the target cell according to the handover configuration information, so that the efficiency of the handover procedure may be improved.

In another possible implementation manner, the geographic position information and/or the azimuth information of the target cell associated with the configuration information of the candidate cell in the handover configuration information may be determined according to the target auxiliary information, a sixth association relationship, and the fourth association relationship, where the sixth association relationship is used to represent an association relationship between the configuration information of the candidate cell in the handover configuration information and the target auxiliary information, and the antenna angle is adjusted according to the geographic position information and/or the azimuth information of the target cell and the geographic position information of the terminal device.

Specifically, the sixth association relationship may be included in the first message, where the sixth association relationship is used to represent an association relationship between configuration information of the candidate cell and the target auxiliary information in the handover configuration information, and the handover configuration information may be understood as handover candidate cell configuration information and may also be understood as synchronous reconfiguration configuration information.

Since after receiving the target auxiliary information, the geographic location information and/or the azimuth information of the target cell signal source corresponding to the target auxiliary information can be determined according to the fourth association relationship, and then the geographic location information and/or the azimuth information of the target cell signal source associated with the configuration information of the candidate cell in the handover configuration information can be determined according to the sixth association relationship as shown in table 9. In this way, the terminal device can adjust the angles of the transmitting and receiving antennas of the terminal device according to the geographic position information and/or azimuth information of the signal source of the target cell and the geographic position information of the terminal device, so that the transmitting and receiving antennas of the terminal device aim at the signal transmitted by the target cell, and the terminal device is switched to the target cell according to the configuration information of the candidate cell in the switching configuration information.

For example, if the first message includes the target auxiliary information 1, the terminal device may determine the geographic location information 1 and/or the azimuth information 1 of the target cell signal source corresponding to the target auxiliary information 1 according to the fourth association relationship, and may determine the geographic location information 1 and/or the azimuth information 1 of the target cell signal source associated with the handover configuration information 1 according to the sixth association relationship. In this way, the terminal device will adjust its own transmitting and receiving antennas according to the geographic position information 1 and/or azimuth information 1 and the geographic position information of the terminal device, and switch to the target cell.

In this embodiment, after determining the geographical location information and/or the azimuth information of the target cell signal source associated with the configuration information of the candidate cell in the handover configuration information, the terminal device may adjust the antenna angle according to the geographical location information and/or the azimuth information and the geographical location information of the terminal device, and then switch to the target cell according to the configuration information of the candidate cell in the handover configuration information, so that the efficiency of the handover procedure may be improved.

Further, the first message further includes indication information, where the indication information is used to indicate content that needs to be reported to the network side device by the terminal device.

Specifically, if the terminal device adjusts the antenna angle according to the target auxiliary information and then measures the signal of the network node, the terminal device also needs to report the measurement result to the network side device. In order to reduce the transmission amount of data, the network side device may include indication information in the generated first message to notify the terminal device of the content that needs to be reported to the network side device.

In addition, the instruction information may be included in the measurement report configuration (measurement report, MR), and configured as shown in table 10:

table 10

Wherein N is a positive integer greater than or equal to 1.

For example, one measurement report configuration is associated with one indication information, that is, there is a one-to-one correspondence between the measurement report configuration and the indication information.

Illustratively, the indication information includes at least one of: measurement Identification (ID) information, PCI information, or Identification information of a target satellite, the measurement Identification ID information being information associated with a target cell and/or a serving cell, the PCI information being PCI information associated with the target cell and/or the serving cell.

The serving cell may be a cell in which the current terminal device is located.

Specifically, the network side device may instruct the terminal device to report one or more of measurement ID information, PCI information, or identification information of the target satellite. For example: the indication information may include only measurement ID information, that is, only measurement ID information associated with the target cell and/or the serving cell; alternatively, the indication information may include measurement ID information and PCI information; alternatively, the indication information may include only preset identification information corresponding to the satellite operation data, that is, identification information of the target satellite, or the indication information may include measurement identification ID information and identification information of the target satellite, or the indication information may include measurement identification ID information, PCI information, identification information of the target satellite, and the like.

Wherein the identification information of the target satellite may include one or more of satellite identification information associated with satellite operation data of the target satellite, orbit identification information associated with satellite operation data of the target satellite, or index information corresponding to satellite operation data of the target satellite.

In this embodiment, since the indication information may include one or more of measurement ID information, PCI information, or identification information of the target satellite, the terminal device may report the measurement result to the network device according to the content in the indication information, so that the transmission amount of data may be reduced, and communication resources may be saved.

In addition, in order to further reduce the transmission amount of data, the indication information is also used for indicating the terminal equipment not to report the signal quality measurement result of the target cell and/or the serving cell; or, the indication information is further used for indicating that the terminal equipment does not need to report the signal quality measurement result of the target cell and/or the service cell and PCI information associated with the target cell and/or the service cell.

Wherein the signal quality measurements comprise cell level measurements and/or beam level measurements.

Specifically, the signal quality may include at least one of the following information: reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ), or signal to interference plus noise ratio (signal to interference plus noise ratio, SINR).

In practical application, the indication information may only include the content that needs to be reported to the network side device, or only include the content that does not need to be reported to the network side device, or both include the content that needs to be reported to the network side device and the content that does not need to be reported to the network side device.

In this embodiment, the indication information is further used to indicate that the terminal device does not need to report content to the network side device, so that the terminal device can be prevented from reporting some irrelevant information, and thus the transmission amount of data can be further reduced.

Further, after adjusting the antenna angle according to the target auxiliary information and measuring the signal of the network node, the terminal device may send a second message to the network side device according to the indication information, where the second message includes measurement information corresponding to the indication information.

The second message may multiplex the dedicated uplink message reporting the measurement result at present, or may be a newly defined dedicated uplink message reporting the measurement result. The dedicated uplink message may be a measurement report message (Measurement Report).

For example, if the indication information includes measurement ID information associated with the target cell and/or the serving cell, and the indication terminal device needs to report the measurement ID information associated with the target cell and/or the serving cell to the network side device, the terminal device may report the measurement ID information associated with the target satellite or the target cell to the network side device after measuring the network node. For example, the measurement information may be reported to the network side device in the manner shown in table 11:

TABLE 11

Measurement ID 1

Measurement of ID 2

……

Measurement ID (N-1)

Measurement of ID N

Wherein N is a positive integer greater than or equal to 1.

If the indication information includes measurement identifier ID information and PCI information associated with the target cell and/or the serving cell, and the indication terminal device needs to report the measurement ID information and PCI information associated with the target cell and/or the serving cell to the network side device, the terminal device reports the measurement ID information and PCI information associated with the target satellite or the target cell to the network side device after measuring the network node. For example, the measurement information may be reported to the network side device in the manner shown in table 12:

Table 12

Wherein N, Q, X and Y are positive integers greater than or equal to 1.

If the indication information includes identification information of the target satellite and the indication terminal equipment needs to report the identification information of the target satellite to the network side equipment, the terminal equipment reports one or more of satellite identification information associated with satellite operation data of the target satellite, orbit identification information associated with satellite operation data of the target satellite or index information corresponding to satellite operation data of the target satellite to the network side equipment after measuring the target satellite. For example, the measurement information may be reported to the network side device in the manner shown in table 13:

TABLE 13

Wherein N is a positive integer greater than or equal to 1.

If the indication information includes measurement ID information associated with the target cell and/or the serving cell and identification information of the target satellite, and the indication terminal device needs to report the measurement ID information and the identification information of the target satellite to the network side device, the terminal device reports the measurement ID information associated with the target satellite or the target cell and the identification information of the target satellite to the network side device after measuring the target satellite. For example, the measurement information may be reported to the network side device in the manner shown in table 14:

TABLE 14

Wherein N, Q, X and Y are positive integers greater than or equal to 1.

If the indication information includes PCI information associated with the target cell and/or the serving cell and the indication terminal device needs to report the measurement ID information associated with the target cell and/or the serving cell to the network side device, the terminal device reports the PCI information associated with the target satellite or the target cell to the network side device after measuring the network node.

If the indication information includes measurement ID information, PCI information and identification information of the target satellite associated with the target cell and/or the serving cell, and the indication terminal device needs to report the measurement ID information, PCI information and identification information of the target satellite to the network side device, the terminal device will report the measurement ID information, PCI information and identification information of the target satellite associated with the target satellite or the target cell to the network side device after measuring the target satellite. For example, the measurement information may be reported to the network side device in the manner shown in table 15:

TABLE 15

Wherein N, Q, X and Y are positive integers greater than or equal to 1.

In this embodiment, after the terminal device measures the signal of the network node after adjusting the antenna angle, a second message may be sent to the network side device according to the indication information, where the second message includes content corresponding to the indication information, so that the network side device may learn the measurement result in time, and reduce the delay of the measurement or switching procedure of the terminal device.

According to the communication method provided by the embodiment of the application, the network side equipment generates the first message and sends the first message to the terminal equipment, the first message comprises target auxiliary information, the target auxiliary information is used for representing the identification information of the network node, the network node comprises a target satellite or a target cell, and the terminal equipment measures the signal of the network node after adjusting the antenna angle or switches to the network node after adjusting the antenna angle according to the received target auxiliary information. Because the network side equipment can send the identification information of the network node to the terminal equipment, the process that the terminal equipment uses the directional antenna to carry out blind trial can be avoided, the terminal equipment can directly carry out signal measurement on the network node corresponding to the identification information according to the identification information sent by the network side equipment after adjusting the angle of the antenna, or switch to the network node after adjusting the angle of the antenna, thereby reducing the time delay of the terminal equipment in the switching process or the cell reselection process, reducing the risk of the terminal equipment off-line, and further improving the continuous performance experience of the terminal equipment service.
