The terminal device according to the embodiments of the present application may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application.
The network device according to the embodiment of the present application may be a base station, and the base station may include a plurality of cells for providing services to a terminal. A base station may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network device may be configured to exchange received air frames with Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network.

In some network architectures, a network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.
Fig. 2 is a schematic structural diagram of a satellite communication system according to an embodiment of the present disclosure. As shown in fig. 2, the communication system may include satellites 21 and 22, a terminal device 23, and a gateway station 24, and wireless communication may be performed between the terminal device 23 and the satellites 21 and 22. In the embodiment of the present application, the number of satellites, terminal devices, and gateway stations is not limited.
As shown in fig. 2, a link between the terminal device 23 and the satellite 21 and the satellite 22 is referred to as a service link, and the terminal device 23 accesses the satellite network through the service link and initiates services such as calling and surfing. The links between the satellites 21 and 22 and the gateway station 24 are called feeder links, by which the gateway station 24 controls the switching between the satellites. As shown in fig. 2, both satellite 21 and satellite 22 cover the ground with multiple beams. In addition, a wireless link exists between the satellites, and signaling interaction and user data transmission between the base stations are completed.
The satellite shown in fig. 2 may be a transparent forwarding satellite, which only performs signal amplification and radio frequency conversion, or a regenerated satellite, which has all or part of the functions of a base station. The satellite may be a Low Earth Orbit (LEO) satellite, a Medium Earth Orbit (MEO) satellite, a geostationary Orbit (GEO) satellite, a High Elliptic Orbit (HEO) satellite, or the like. For example, LEO satellites typically have orbital altitudes ranging from 500km to 1500km, and orbital periods (periods of rotation around the earth) of about 1.5 hours to 2 hours. The maximum satellite visibility time is about 20 minutes, which is the longest time that the beam of the satellite covers a certain area of the ground, and the LEO satellite moves relative to the ground, and the ground area covered by the LEO satellite changes 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 GEO satellite typically has an orbital altitude of 35786km and an orbital period of 24 hours. In order to ensure the coverage of the satellite and increase the system capacity of the communication network, the satellite may cover the ground by 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 having 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, the terminal device generally needs to be handed over from one cell to another cell or reselected from one cell to another cell, for example, handed over from 1 to 2 in fig. 1 or reselected from 1 to 2. Generally, 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 premise 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 the form of a measurement report, and the source base station selects one or more suitable target base stations for the terminal device according to the measurement report reported by the terminal device and initiates a handover request process.
For the cell reselection process, the terminal can determine a measurement target according to the system information broadcasted by the service cell and the effective special frequency point priority information, measure the signal quality of the base station in the adjacent cell when the measurement triggering condition is met, and once the reselection condition is met, the terminal can initiate a cell reselection process.
In the satellite communication system shown in fig. 2, the satellite switching 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) handover between cells in the same satellite in different gateway stations. Taking scene 2 as an example, when the terminal device is about to be disconnected from the satellite 21, the network-side device may trigger the terminal device to switch from the satellite 21 to the satellite 22, where if the satellite is a transparent forwarding satellite or a regenerated satellite with only Distributed Units (DUs) on the satellite, the switching process is triggered by the gateway station, and if the satellite is a regenerated satellite with Centralized Units (CUs) on the satellite, the switching process is triggered by the satellite itself, so that it can be seen that angles at which the terminal device receives different satellite signals are different.
For the satellite communication system, the process of cell reselection performed by the terminal device is similar to the process of cell handover, which also includes the above four scenarios, and for the process of cell reselection, details are not repeated here.
However, in a communication system, a high frequency band is sometimes used. Particularly, in a satellite communication system, a used frequency spectrum range is wider, from several GHz to several tens of GHz, and if a high-frequency band such as Ka band is adopted, the high-frequency electromagnetic wave has a shorter wavelength and the volatility is deteriorated compared with a low frequency band, so that a terminal device generally selects a directional antenna to obtain an additional antenna gain. For a terminal device using a directional antenna, since the directional antenna has a 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 the target cell in several candidate cells or searching for the target satellite if following the above-mentioned measurement or handover procedure. However, the speed of one LEO satellite sweeping the ground can reach several kilometers per second, and the time for providing signal service for the terminal device is several seconds, which may cause a delay in a handover procedure or a cell reselection procedure to be large if the terminal device consumes a large amount of time to search for a target cell or a target satellite. If the terminal device cannot find the target cell in time or the target satellite initiates an access process, the terminal device may have a risk of network disconnection, thereby reducing the continuous performance experience of the terminal device service. Therefore, how to determine the direction of the target satellite or the target cell in time is very important for the terminal equipment using the directional antenna.
In view of the foregoing problems, an embodiment of the present application provides a communication method, 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, and 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, measures a signal of the network node, or adjusts the 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 a directional antenna to perform blind trial can be avoided, the terminal equipment can directly measure signals of the network node corresponding to the identification information after adjusting the antenna angle according to the identification information sent by the network side equipment, or switch to the network node after adjusting the antenna angle, so that the time delay of the terminal equipment during a switching process or a cell reselection process can be reduced, the risk of the terminal equipment going off the network is reduced, and the continuity performance experience of the terminal equipment service is improved.
The following describes the technical solution of the communication method provided in the present application in detail through a detailed embodiment. It is to be understood that the following detailed description may be combined with other embodiments, and that the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a signaling diagram of a communication method provided in this embodiment of the present application, and it should be noted that, although in this 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 this 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 terrestrial 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 may be understood as a base station, and the base station sends a first message generated after generating the first message to the satellite, and forwards the signal to a terminal device after performing amplification processing and radio frequency conversion processing on the signal by the satellite. If the satellite is a regenerative satellite, the network-side device can be understood as the regenerative satellite.
Illustratively, the first message may be included in a cell broadcast message or higher layer dedicated signaling. In a possible implementation manner, for a connected terminal device, the first message may be a higher layer dedicated signaling, and for an idle terminal device, the first message may be a cell broadcast message, such as a System Information Block (SIB).
The high-layer dedicated signaling may refer to signaling sent by a high-layer protocol layer, and the high-layer protocol layer is at least one protocol layer above a physical layer. The higher layer protocol layer may specifically include at least one of the following protocol layers: a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, a non-access stratum (NAS) layer, and the like, the higher layer signaling may include RRC signaling, a MAC Control Element (CE), and the like.
In addition, the target assistance information may be used to represent identification information of a network node that includes 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 comprises a target satellite, the target assistance information may comprise at least one 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, or index information corresponding to the satellite operation data of the target satellite.
In particular, the satellite operation data can be understood as an Ephemeris (Ephemeris) in the satellite domain. Through an ephemeris, initial position state vector information of a satellite at a certain defined time starting point can be obtained, generally, the time starting point information is public and is not bound with a certain satellite independently, and 6 parameters are needed to represent operation data of the satellite, 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 acquired, the spatial position information of the satellite at any future time point can be accurately calculated.
The satellite operation data can be provided through a non-access stratum or an access stratum.
For example, the satellite operation data and the satellite identification information may be associated by an explicit index method in table 1, or may be understood as establishing a corresponding relationship between the satellite operation data and the satellite identification information, where the satellite operation data and the satellite identification information in table 1 have a one-to-one corresponding relationship.
TABLE 1
Figure BDA0002623705440000171
The target auxiliary information includes satellite identification information associated with the satellite operation data of the target satellite, and the satellite operation data corresponding to the satellite identification information can be obtained according to the satellite identification information through the index relationship in table 1. For example: if the target auxiliary information includes the satellite identification information 2, the satellite operation data 2 corresponding to the satellite identification information 2 may be determined according to table 1.
For example, the satellite operation data may be associated with the orbit identification information of the satellite by an explicit index method in table 2, or it may be understood that a corresponding 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 relationship with the orbit identification information of the satellite.
TABLE 2
Figure BDA0002623705440000181
When the target auxiliary information includes the 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 according to the orbit identification information through the index relationship in table 2. For example: if the target auxiliary information includes the orbit identification information M-1, the satellite operation data M-1 corresponding to the satellite identification information M-1 can be determined according to table 2.
For example, all the satellite operation data may form a list, and each satellite operation data is associated with index (index) information of the satellite operation data in the list in a manner shown in table 3, or it may be understood that a corresponding relationship is established between the satellite operation data and the index information. The satellite operation data in table 3 has a one-to-one correspondence relationship with the index information.
TABLE 3
Figure BDA0002623705440000182
It should be understood that the index information 1 indicates that the index value of the 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 may be obtained according to the index information through the correspondence relationship in table 3. For example: if the target auxiliary information includes index information 1, the satellite operation data 1 corresponding to the index information 1 may be determined according to table 3.
Wherein M in tables 1 to 3 is a positive integer greater than or equal to 1.
It is to be understood that the target assistance information may include only the satellite identification information, the orbit identification information, or the index information, or may include two or more of the above information at the same time, for example, the target assistance information may include the satellite identification information and the orbit identification information at the same time.
Through the correspondence shown in tables 1 to 3, after receiving the target auxiliary information, the terminal device can determine the satellite operation data of the target satellite, so that the spatial position information of the target satellite at any future time point can be calculated.
In this embodiment, since the data volume of the satellite operation data is large, one or more of the satellite identification information associated with the satellite operation data of the target satellite, the orbit identification information associated with the satellite operation data of the target satellite, or the 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 that the satellite operation data is directly embedded in the measurement configuration or the switching configuration and transmitted to the terminal device, thereby reducing the transmission volume of the data and saving the communication resources.
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 a signal source of the target cell.
Specifically, the geographic location information may be longitude and latitude information, and the orientation information may be direction information. In the terrestrial communication system, the target auxiliary information may only include the geographical location information of the signal source of the target cell to be measured or handed over, may only include the direction information of the signal source of the target cell to be measured or handed over, and may also include the geographical location information and the direction information of the signal source of the target cell to be measured or handed over. Therefore, after the network side device sends the target auxiliary information to the terminal device, the terminal device can determine the position or the direction of the target cell according to the geographical position information and/or the azimuth information.
In this embodiment, the geographical location information and/or the azimuth information of the target cell signal source is set in the target auxiliary information to notify the terminal device of the location or the direction of the target cell, so that a phenomenon that the terminal device searches the target cell first and then measures or switches the target cell to the target cell can be avoided, and thus the time delay of measuring or switching the target cell 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 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 target auxiliary information.
In this step, when the network node includes the target satellite, the terminal device may determine spatial position information of the target satellite according to the target auxiliary information, and adjust a receiving antenna angle of the terminal device, so that the receiving antenna of the terminal device is aligned to a signal transmitted by the target satellite, thereby measuring a signal of the target satellite, or switching to the target satellite.
As for the method for adjusting the antenna angle according to the target auxiliary information, in a 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 relation and a second association relation, where the first association relation is used to represent the association relation between the measurement frequency point and the target auxiliary information, the second association relation is used to represent the association relation 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 geographical location information of the terminal device.
Specifically, the second 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 a plurality of pieces of auxiliary information and a plurality of pieces of satellite operation data, and the auxiliary information and the satellite operation data have a one-to-one correspondence relationship. For example: the assist information 1 corresponds to the satellite operation data 1, and the assist information 2 corresponds to the satellite operation data 2 and … … corresponds to the assist 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 the plurality of auxiliary information in the second association relationship. The first association relationship may be as shown in table 4:
TABLE 4
Figure BDA0002623705440000191
Wherein N in table 4 is a positive integer greater than or equal to 1.
Illustratively, a Measurement Object (MO) includes a measurement frequency point, and one measurement frequency point information is associated with one target auxiliary information. That is, there is a one-to-one correspondence between the measurement object, the measurement frequency point, and the target auxiliary information.
The measurement frequency point may be a satellite frequency point, or a synchronization signal and Physical Broadcast Channel (PBCH) block (SSB), or a channel state information-reference signal (CSI-RS), or a cell frequency point.
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 shown in table 4, so that the terminal device can adjust the angle of the receiving antenna thereof according to the satellite operation data of the target satellite and the geographical position information of the terminal device, so that the receiving antenna of the terminal device is aligned with 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
Figure BDA0002623705440000201
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, according to the second association relationship, the satellite operation data 1 corresponding to the target auxiliary information 1, and then may determine, according to the first association relationship, the satellite operation data 1 of the target satellite associated with the measurement frequency point 1. Therefore, the terminal equipment adjusts the receiving antenna of the terminal equipment according to the satellite operation data 1 of the target satellite and the geographical position information of the terminal equipment, and then measures the signal of the target satellite according to the measuring 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 geographical 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 measuring the directional antenna signal may be improved.
In another possible implementation manner, according to the target auxiliary information, a third association relationship and the second association relationship, satellite operation data of a target satellite associated with a target Physical Cell Identifier (PCI) configured on the measurement frequency point is determined, the target PCI is any one of a plurality of PCIs configured on the measurement frequency point, the third association relationship is used for representing 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 the geographical location information of the terminal device, the signal of the target satellite is measured after the antenna angle is adjusted.
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. Wherein the third correlation may be as shown in table 6:
TABLE 6
Figure BDA0002623705440000202
Figure BDA0002623705440000211
Wherein P, Q, N, X and Y in Table 6 are both positive integers greater than or equal to 1.
Illustratively, a Measurement Object (MO) includes a measurement frequency point, and one measurement frequency point information is associated with one or more pieces of PCI information, and one piece of PCI is associated with one piece of target auxiliary information.
The measurement frequency point can be a satellite frequency point, an SSB, a CSI-RS or a cell frequency point.
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 target PCI configured on the measurement frequency point can be determined according to the third association relationship shown in table 6.
For example, according to the target auxiliary information, the third association relationship and the second association relationship, the determined satellite operation data of the target satellite associated with the target PCI configured at the measurement frequency point may be as shown in table 7:
TABLE 7
Figure BDA0002623705440000212
Wherein P, Q, N, X and Y in Table 7 are both positive integers greater than or equal to 1.
For example, if the first message includes the target auxiliary information 11, the terminal device may determine, according to the second association relationship, the satellite operation data 1 corresponding to the target auxiliary information 11, and then may determine, according to the third association relationship, the satellite operation data 1 of the target satellite associated with the target PCI11 configured on the measurement frequency point 1. In this way, the terminal device adjusts its own receiving antenna according to the satellite operation data 1 of the target satellite and the geographical location information of the terminal device, and then measures the signal of the target satellite according to the measurement frequency point 1 and the target PCI11 configured thereon.
It can be understood that, when the target satellite is measured, 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, for each measurement frequency point, it is required to blindly try a maximum of 1008 kinds of PCI information to determine the target PCI. 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 the blind trial process. The space scanning process of the directional antenna is independent of the measuring frequency point and the PCI determining process, and the target auxiliary information can improve the signal measuring efficiency of the directional antenna of the terminal no matter whether the target auxiliary information configured on the network side is only associated with the measuring frequency point or is simultaneously associated with the configured measuring frequency point and the PCI information.
In this embodiment, after the terminal device determines the satellite operation data of the target satellite associated with the target PCI configured on the measurement frequency point, the antenna angle may be adjusted according to the satellite operation data and the geographic position information of the terminal device, and then the signal of the target satellite is measured according to the measurement frequency point and the target PCI, so that the efficiency of measuring the directional antenna signal may be improved.
In addition, when the terminal device is switched to the target satellite, the antenna angle of the terminal device also needs to be adjusted first, in a 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 relation and a second association relation, the fifth association relation is used for representing the association relation between the switching configuration information and the target auxiliary information, the second association relation is used for representing the association relation 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, and the association relationship is used to represent a correspondence relationship between a plurality of pieces of assistance information and a plurality of pieces of satellite operation data, and the assistance information and the satellite operation data have a one-to-one correspondence relationship. For example: the assist information 1 corresponds to the satellite operation data 1, and the assist information 2 corresponds to the satellite operation data 2 and … … corresponds to the assist information P.
A fifth association relationship may be included in the first message, where the fifth association relationship is used to indicate an association relationship between the handover configuration information and the target auxiliary information, where the handover configuration information may be understood as handover candidate cell configuration information or 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 relationship. Wherein, the fifth association relationship may be as shown in table 8:
TABLE 8
First message
Handover configuration information
Target assistance information
Wherein the first message includes a set of handover configuration information, and the set of handover configuration information is associated with a target assistance information.
After receiving the target auxiliary information, the satellite operation data corresponding to the target auxiliary information may be determined according to the second association relationship, and then the satellite operation data of the target satellite associated with the handover configuration information may be determined according to the fifth association relationship as shown in table 8, so that the terminal device may adjust its transmitting and receiving antenna angle according to the satellite operation data of the target satellite and the geographical location information of the terminal device, and align the transmitting and receiving antenna of the terminal device with the target satellite, thereby switching to the target satellite according to the handover configuration information.
For example, if the first message includes the target assistance information 1, the terminal device may determine, according to the second association relationship, the satellite operation data 1 corresponding to the target assistance information 1, and then may determine, according to the fifth association relationship, the satellite operation data 1 of the target satellite associated with the handover configuration information. In this way, the terminal device will adjust its transmitting and receiving antennas according to the satellite operation data 1 of the target satellite and the geographical location information of the terminal device, and then switch 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 position 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, the satellite operation data of the target satellite associated with the configuration information of the candidate cell in the handover configuration information is determined according to the target assistance information, a sixth association relation and the second association relation, where the sixth association relation is used to represent the association relation between the configuration information of the candidate cell in the handover configuration information and the target assistance information, and the antenna angle is adjusted according to the satellite operation data of the target satellite and the geographical location information of the terminal device.
Specifically, a sixth association relationship may be included in the first message, where the sixth association relationship is used to indicate an association relationship between configuration information of candidate cells in the handover configuration information and the target auxiliary information, where the handover configuration information may be understood as handover candidate cell configuration information or may also be understood as synchronous reconfiguration configuration information. Wherein, the sixth association relationship may be as shown in table 9:
TABLE 9
Figure BDA0002623705440000231
The first message includes one or more groups of handover configuration information, and each group of handover configuration information is associated with one target auxiliary information.
Since the satellite operation data corresponding to the target assistance information can be determined according to the second association after the target assistance information is received, the satellite operation data of the target satellite associated with the configuration information of the candidate cell in the handover configuration information can be determined according to the sixth association as shown in table 9. Therefore, the terminal equipment can adjust the angle of the transmitting and receiving antenna of the terminal equipment according to the satellite operation data of the target satellite and the geographical position information of the terminal equipment, so that the transmitting and receiving antenna of the terminal equipment is aligned to the target satellite, and the target satellite is switched according to the configuration information of the candidate cell in the switching configuration information.
For example, if the first message includes the target assistance information 1, the terminal device may determine, according to the second association relationship, the satellite operation data 1 corresponding to the target assistance information 1, and then may determine, according to the sixth association relationship, the satellite operation data 1 of the target satellite associated with the handover configuration information 1. In this way, the terminal device will adjust its transmitting and receiving antennas according to the satellite operation data 1 of the target satellite and the geographical location information of the terminal device, and then switch 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 position 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 process may be improved.
For example, when the network node includes a target cell, the terminal device may determine the position information or the direction information of the target cell according to the target auxiliary information, and adjust its antenna angle, so that the antenna of the terminal device is aligned to a signal sent by the target cell, thereby measuring the signal of the target cell, or switching to the target cell.
As for the method of adjusting the antenna angle according to the target auxiliary information, in a possible implementation manner, the geographical location information and/or the orientation information of the target cell associated with the measurement frequency point may be determined according to the target auxiliary information, the first association relationship and the 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, the fourth association relationship is used to represent the association relationship between the auxiliary information and the geographical location information and/or the orientation information, and then the antenna angle is adjusted according to the geographical location information and/or the orientation information of the target cell and the geographical location 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 a plurality of pieces of auxiliary information and a plurality of pieces of geographical location information and/or orientation information, and the auxiliary information has a one-to-one correspondence relationship with the geographical location information and/or the orientation information. For example: the assistance information 1 corresponds to the geographical position information 1 and/or the direction information 1, and the assistance information 2 corresponds to the geographical position information 2 and/or the direction information 2, … … and the assistance information P corresponds to the geographical position information P and/or the direction information P.
The first association relationship may be included in the first message, where the first association relationship is used to indicate an association relationship between the measurement frequency point and the target auxiliary information, and the target auxiliary information is any one of the plurality of auxiliary information in the fourth association relationship. Wherein the first association relationship may be as shown in table 4.
After receiving the target auxiliary information, the geographical 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 geographical position information and/or the azimuth information of the target cell signal source associated with the measurement frequency point can be determined according to the first association relationship shown in table 4.
For example, if the first message includes the target auxiliary information 1, the terminal device may determine, according to the fourth association relationship, the geographic location information 1 and/or the azimuth information 1 corresponding to the target auxiliary information 1, and then may determine, according to the first association relationship, the geographic location information 1 and/or the azimuth information 1 associated with the measurement frequency point 1 of the measurement object 1. Therefore, the terminal equipment adjusts the receiving antenna of the terminal equipment according to the geographic position information 1 and/or the azimuth information 1 and the geographic position information of the terminal equipment, and then measures the signal of the target cell according to the measuring 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, thereby improving the efficiency of measuring the directional antenna signal.

After receiving the target auxiliary information, the geographical location information and/or the azimuth information corresponding to the target auxiliary information may be determined according to the fourth association relationship, and then 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 may be determined according to the third association relationship as shown in table 6. Therefore, the terminal equipment can adjust the angle of the receiving antenna of the terminal equipment according to the geographical position information and/or the azimuth information of the signal source of the target cell and the geographical position information of the terminal equipment, so that the receiving antenna of the terminal equipment is aligned to the signal sent by the target cell, and then the signal of the target cell is measured according to the measuring frequency point and the target PCI configured on the measuring frequency point.
For example, if the first message includes the target auxiliary information 11, the terminal device may determine, according to the fourth association relationship, the geographic location information 1 and/or the direction information 1 corresponding to the target auxiliary information 1, and then may determine, according to the third association relationship, the geographic location information 1 and/or the direction information 1 associated with the target PCI11 configured on the measurement frequency point 1 of the measurement object 1. In this way, the terminal device may adjust its own receiving antenna according to the geographic location information 1 and/or the azimuth information 1 and the geographic 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.

A fifth association relationship may be included in the first message, where the fifth association relationship is used to indicate an association relationship between the handover configuration information and the target auxiliary information, where the handover configuration information may be understood as handover candidate cell configuration information or may also be understood as synchronization reconfiguration information. The target auxiliary information is any one of a plurality of auxiliary information in the second association relationship.
After receiving the target auxiliary information, the geographical location information and/or the bearing information of the target cell signal source corresponding to the target auxiliary information may be determined according to the fourth association relationship, and then the geographical location information and/or the bearing information of the target cell signal source associated with the handover configuration information may be determined according to the fifth association relationship as shown in table 8. Therefore, the terminal equipment can adjust the angles of the sending and receiving antennas thereof according to the geographical position information and/or the azimuth information of the signal source of the target cell and the geographical position information of the terminal equipment, so that the sending and receiving antennas of the terminal equipment are aligned to the signal sent by the target cell, and the signal is switched to the target cell according to the switching configuration information.
For example, if the first message includes target auxiliary information 1, the terminal device may determine, according to the fourth association relationship, geographic position information 1 and/or direction information 1 of the target cell signal source corresponding to the target auxiliary information 1, and then may determine, according to the fifth association relationship, geographic position information and/or direction information of the target cell signal source associated with the handover configuration information. Therefore, the terminal equipment adjusts the sending and receiving antennas thereof according to the geographical position information and/or the azimuth information of the signal source of the target cell and the geographical position information of the terminal equipment, and then switches to the target cell according to the switching configuration information.

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

The second message may be a dedicated uplink message for reporting the measurement result at present, or may be a newly defined dedicated uplink message for reporting the measurement result. The dedicated uplink message may be a Measurement Report message (Measurement Report).
For example, if the indication information includes measurement identifier ID information associated with the target cell and/or the serving cell and indicates that the 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 measurement ID information associated with the target satellite or the target cell to the network side device after measuring the network node.
