In a communication system, in general, the terminal device completes the handover from the current serving base station to another base station through the measurement reporting mechanism. The measurement reporting mechanism of the terminal device is the prerequisite for the source base station to select the appropriate target base station for the terminal device. The measurement configuration on the network side measures the signal quality of neighboring base stations when the measurement trigger conditions are met, and reports it to the source base station in the form of a measurement report.

For example, the network device involved in the embodiments of the present application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile Communications (GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA). ), it can also be a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or it can be an evolved network device in a long term evolution (LTE) system (evolutional Node B, eNB or e-NodeB), 5G base station (gNB) in 5G network architecture (next generation system), or Home evolved Node B (HeNB), relay node (relay node) , a home base station (femto), a pico base station (pico), etc., which are not limited in the embodiments of the present application.

FIG. 2 is a schematic structural diagram of a satellite communication system according to an embodiment of the present application. 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 can be performed between the terminal device 23 and the

satellites

21 and 22 . The number of satellites, terminal devices, and gateway stations is not limited in this embodiment of the present application.

As shown in FIG. 2 , the link between the terminal device 23 and the

satellites

21 and 22 is called a service link. The terminal device 23 accesses the satellite network through the service link and initiates services such as calling and surfing the Internet. The link between the

satellites

21 and 22 and the gateway station 24 is called a feeder link, and the gateway station 24 controls the switching between the satellites through the feeder link. As shown in FIG. 2 , both

satellites

21 and 22 use multiple beams to cover the ground. In addition, there is a wireless link between satellites to complete signaling interaction and user data transmission between base stations.

The satellite shown in FIG. 2 may be a transparent relay satellite or a regeneration satellite, wherein the transparent relay satellite only performs signal amplification and radio frequency conversion, and the regeneration satellite has all or part of the base station functions. The satellites can be low earth orbit (low earth orbit, LEO) satellites, medium earth orbit (medium earth orbit, MEO) satellites, geostationary earth orbit (GEO) satellites, high elliptical orbit (High Elliptical Orbit, HEO) satellites Wait. For example, the orbital altitude of LEO satellites is usually in the range of 500km to 1500km, and the orbital period (the period of rotation around the earth) is about 1.5 hours to 2 hours. The maximum visible time of the satellite is about 20 minutes. The maximum visible time refers to the longest time that the beam of the satellite covers a certain area of the ground. The LEO satellite moves relative to the ground. As the satellite moves, the ground area it covers is also the same. changing. The signal propagation distance of the LEO satellite is short, the link loss is small, and the transmission power requirements of the terminal equipment are not high. The orbital altitude of GEO satellites is usually 35786km, and the orbital period is 24 hours. In order to ensure the coverage of satellites and improve the system capacity of the communication network, satellites can use multiple beams to cover the ground. For example, a satellite can form tens or hundreds of beams to cover the ground, and a beam can cover tens to hundreds of kilometers in diameter ground area.

In the terrestrial communication system shown in Fig. 1, after the service performance and communication quality of the terminal equipment are degraded, the terminal equipment usually needs to be handed over from one cell to another cell or reselected from one cell to another cell, for example, from Fig. Cell 1 in 1 is handed over to cell 2, or reselection from cell 1 to cell 2. In general, the terminal equipment needs to complete the handover from the current serving base station to another base station through the measurement reporting mechanism. The measurement reporting mechanism of the terminal equipment is the premise that the source base station selects the appropriate target base station for the terminal equipment. Configure to measure the signal quality of neighboring base stations when the measurement trigger conditions are met, and report it to the source base station in the form of a measurement report. 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 Switch request process.

In the satellite communication system shown in Figure 2, satellite handover includes a variety of scenarios: (1) handover between cells within the same gateway within the same gateway; (2) handover between cells between different satellites within the same gateway; (3) Handover between cells in different gateways and between different satellites; (4) In different gateways, handover between cells in the same satellite. Taking scenario 2 as an example, when the terminal device is about to be separated from the satellite 21 signal, the network side device will trigger the terminal device to switch from the satellite 21 to the satellite 22. If the satellite is a transparent relay satellite or only a distributed unit (DU) For the regeneration satellite on the satellite, the switching process is triggered by the gateway station. If the satellite is a regeneration satellite of a centralized unit (CU) on the satellite, the switching process is triggered by the satellite itself. It can be seen that the terminal equipment receives different The angle of the satellite signal is different.

In the satellite communication system, the process of cell reselection by the terminal equipment is similar to the process of cell handover, which also includes the above four scenarios, and the process of cell reselection is not repeated here.

However, in communication systems, high frequency bands are sometimes used. Especially in satellite communication systems, the spectrum used is wider, ranging from several GHz to tens of GHz. If high-frequency frequency bands such as Ka-band are used, compared with low-frequency waves, due to the shorter wavelength of high-frequency electromagnetic waves, the volatility will be worse. , therefore, 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 the target satellite or target cell, if the terminal device follows the above measurement or handover process, it may take a lot of time to search in several candidate cells. target cell, or search for the target satellite. However, usually a LEO satellite can swipe the ground at a speed of several kilometers per second, and the time it can provide signal services for terminal equipment is only a few seconds. If the terminal equipment spends a lot of time searching for the target cell or target satellite, it will cause handover. The process or the cell reselection process has a relatively long delay. If the terminal device cannot find the target cell in time or the target satellite initiates the access process, the terminal device may be at risk of being disconnected from the network, thereby reducing the service continuity performance experience of the terminal device. Therefore, how to determine the direction of the target satellite or the target cell in time is very important for the terminal device using the directional antenna.

In consideration of the above problems, the embodiment of the present application proposes a communication method. The network side device generates a first message and sends the first message to the terminal device. The first message includes target auxiliary information, and the target The auxiliary information is used to represent the identification information of the network node, wherein the network node includes the target satellite or the target cell, and the terminal device adjusts the antenna angle and measures the signal of the network node according to the received target auxiliary information or switches to the network after adjusting the antenna angle. node. Since the network-side device can send the identification information of the network node to the terminal device, the process of blindly trying the terminal device using the directional antenna can be avoided, and the terminal device can directly adjust the antenna angle according to the identification information sent by the network-side device. The network node corresponding to the identification information measures the signal, or switches to the network node after adjusting the antenna angle, so as to reduce the delay in the terminal device handover process or the cell reselection process, reduce the risk of the terminal device being disconnected from the network, and improve the It improves the continuous performance experience of terminal device services.

Below, the technical solution of the communication method provided by the present application will be described in detail through detailed embodiments. It can be understood that the following specific embodiments may be combined with each other, and 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 by an embodiment of the present application. It should be noted that although the steps of the method are presented in a specific order in the embodiments of the present application, they may be implemented in different embodiments. The order of the steps is varied, and in some embodiments, one or more of the steps shown in the sequence shown in this specification may be performed concurrently. As shown in Figure 3, the method includes:

Step 301: The network side device generates a first message, where the first message includes target assistance information, where the target assistance information is used to represent identification information of a network node, and the network node includes a target satellite or a target cell.

Among them, in the terrestrial communication system, the network side device can be understood as a base station. In a satellite communication system, if the satellite only performs signal amplification and radio frequency conversion, the network-side device can be understood as a base station. After the base station generates the first message, it sends the generated first message to the satellite, and the signal is processed by the satellite. After amplification processing and radio frequency conversion processing, it is forwarded to the terminal equipment. If the satellite is a regenerative satellite, the network side device can be understood as the above-mentioned regenerative satellite.

Exemplarily, the above-mentioned first message may be included in a cell broadcast message or high-level dedicated signaling. In a possible implementation manner, for a terminal device in a connected state, the first message may be a high-level dedicated signaling, and for a terminal device in an idle state, the first message may be a cell broadcast message, such as a system information block (System Information Block). , SIB).

The high-level dedicated signaling may refer to signaling sent by a high-level protocol layer, and the high-level protocol layer is at least one protocol layer above the physical layer. The high-level 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 (packet data convergence) protocol, PDCP) layer, radio resource control (radio resource control, RRC) layer, and non-access stratum (non-access stratum, NAS), etc., the high-level signaling may include RRC signaling, MAC control element (control element, CE) )Wait.

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 that the terminal device needs to measure or hand over, and the target cell is a cell that the terminal device needs to measure or hand over.

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

Specifically, the above-mentioned satellite operation data can be understood as an ephemeris in the satellite field. Through the ephemeris map, you can know the initial position state vector information of the satellite at a defined time starting point. Usually, the time starting point information is public and does not need to be bound to a satellite separately, and 6 parameters are required to characterize a satellite. Operation data, in which 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 obtaining the satellite operation data of a certain satellite, the spatial position information of the satellite at any point in the future can be accurately calculated.

Among them, the satellite operation data can be provided through the non-access layer or through the access layer.

Exemplarily, the satellite operation data can be associated with the satellite identification information through the explicit indexing method in Table 1, or it can also be understood as establishing a corresponding relationship between the satellite operation data and the satellite identification information, wherein, the satellites in Table 1 There is a one-to-one correspondence between the operation data and the satellite identification information.

Table 1

The target assistance information includes satellite identification information associated with the satellite operation data of the target satellite. Through the index relationship in Table 1, the satellite operation data corresponding to the satellite identification information can be obtained according to the satellite identification information. For example, if the satellite identification information 2 is included in the target assistance information, according to Table 1, the satellite operation data 2 corresponding to the satellite identification information 2 can be determined.

Exemplarily, the satellite operation data can be associated with the orbit identification information of the satellite through the explicit index method in Table 2, or it can also be understood as establishing a correspondence between the satellite operation data and the orbit identification information of the satellite. Wherein, 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, through the index relationship in Table 2, the satellite operation data corresponding to the orbit identification information can be obtained according to the orbit identification information. For example, if the target assistance information includes orbit identification information M-1, then according to Table 2, the satellite operation data M-1 corresponding to the satellite identification information M-1 can be determined.

Exemplarily, all satellite operation data can also be formed into a list, and each satellite operation data can be associated with the index information of the satellite operation data in the list in the manner shown in Table 3, Or it can also be understood as establishing a correspondence between the satellite operation data and the index information. Among them, the satellite operation data in Table 3 has a one-to-one correspondence with the index information.

table 3

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 assistance information includes index information corresponding to the satellite operation data of the target satellite, through the correspondence in Table 3, the satellite operation data corresponding to the index information can be obtained according to the index information. For example, if the target assistance information includes index information 1, according to Table 3, the satellite operation data 1 corresponding to the index information 1 can be determined.

Wherein, M in Table 1-Table 3 is a positive integer greater than or equal to 1.

It can be understood that the target assistance information may only contain satellite identification information, orbit identification information or index information, or two or more of the above-mentioned information at the same time. For example, the target assistance information may contain both satellite identification information and orbit information. identification information.

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

In this embodiment, since the data volume of the satellite operation data is relatively large, the satellite identification information associated with the satellite operation data of the target satellite and the orbit identification information associated with the satellite operation data of the target satellite may be set in the target assistance information Or one or more of the index information corresponding to the satellite operation data of the target satellite, and the target satellite is represented by the above information, so as to avoid the phenomenon that the satellite operation data is directly embedded in the measurement configuration or the switching configuration and sent to the terminal device, so as to reduce the The transmission volume of small data saves communication resources.

In another possible implementation manner, when the network node includes the target cell, the target assistance information includes geographic location information and/or orientation information of the 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 a terrestrial communication system, the target assistance information may only include the geographic location information of the signal source of the target cell that needs to be measured or handed over, or may only include the position information of the signal source of the target cell that needs to be measured or handed over. Geographic location information and orientation information of the signal source of the target cell for measurement or handover. In this way, after the network side device sends the target assistance information to the terminal device, the terminal device can determine the location or direction of the target cell according to the geographic location information and/or the orientation information.

In this embodiment, the geographic location information and/or orientation information of the signal source of the target cell is set in the target assistance information to notify the terminal equipment of the location or direction of the target cell, which can prevent the terminal equipment from first searching for the target cell and then searching for the target cell. The phenomenon that the cell performs measurement or is handed over to the target cell, so that the delay of the target cell measurement or handover to the target cell can be reduced.

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

In this step, after generating the first message, the network side device sends the first message to the terminal device.

Step 303: According to the target auxiliary information, the terminal device adjusts the antenna angle and then measures the signal of the network node or switches to the network node after adjusting the antenna angle.

In this step, when the network node includes the target satellite, the terminal device can determine the spatial position information of the target satellite according to the target assistance information, and adjust its own receiving antenna angle, so that the receiving antenna of the terminal device is aligned with the target satellite. signal to measure the signal of the target satellite, or switch to the target satellite.

For the method of adjusting the antenna angle according to the target assistance 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 assistance information, the first correlation relationship and the second correlation relationship , the first correlation is used to represent the correlation between the measurement frequency and the target auxiliary information, the second correlation is used to represent the correlation between the auxiliary information and the satellite operation data, and then according to the satellite operation data of the target satellite And the geographic location information of the terminal device, adjust the antenna angle.

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

The first association relationship may be included in the first message, and the first association relationship is used to represent the association relationship between the measurement frequency point and the target auxiliary information, and the target auxiliary information is any of the plurality of auxiliary information in the second association relationship. One. Among them, the first association relationship can be as shown in Table 4:

Table 4

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

Exemplarily, a measurement object (measurement object, MO) includes a measurement frequency point, and a measurement frequency point information is associated with a target auxiliary information. That is, there is a one-to-one correspondence between measurement objects, measurement frequency points and target auxiliary information.

The above-mentioned measurement frequency points can be satellite frequency points or synchronization signals and physical broadcast channel (physical broadcast channel, PBCH) block (synchronization signal and PBCH block, SSB) or channel state information reference signal (channel state information-reference signal, CSI-RS) or cell frequency.

After receiving the target assistance information, the satellite operation data corresponding to the target assistance information can be determined according to the second association relationship, and then according to the first association relationship shown in Table 4, the measurement frequency can be determined. The satellite operation data of the associated target satellite, so that the terminal device can adjust its own receiving antenna angle 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, Then, according to the measurement frequency point, the signal of the target satellite is measured.

Exemplarily, according to the target assistance 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 target assistance information 1, the terminal device can determine the satellite operation data 1 corresponding to the target assistance information 1 according to the second association relationship, and then determine the measurement frequency according to the first association relationship. Satellite operation data 1 of the target satellite associated with point 1. 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 geographic location information of the terminal device, and then measure 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, the terminal device can adjust the antenna angle according to the satellite operation data and the geographical position information of the terminal device, and then measure the signal of the target satellite according to the measurement frequency. , which can improve the efficiency of directional antenna signal measurement.

In another possible implementation manner, according to the target assistance information, the third association relationship and the second association relationship, determine the target satellite associated with the target physical cell identifier (physical cell identifier, PCI) configured on the measurement frequency point. Satellite operation data, the target PCI is any one of multiple PCIs configured on the measurement frequency point, and 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 Data and geographic location information of terminal equipment, adjust the antenna angle and measure the signal of the target satellite.

Specifically, the third association relationship may be included in the first message, and the third association relationship is used to indicate the association relationship between the PCI configured on the measurement frequency point and the target auxiliary information. Among them, the third association relationship can be as shown in Table 6:

Table 6

Wherein, P, Q, N, X and Y in Table 6 are all positive integers greater than or equal to 1.

Exemplarily, a measurement object (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 a PCI is associated with a piece of target auxiliary information.

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

After receiving the target assistance information, the satellite operation data corresponding to the target assistance information can be determined according to the second association relationship, and then according to the third association relationship shown in Table 6, it can be determined that the measurement frequency The satellite operation data of the target satellite associated with the configured target PCI, so that the terminal device can adjust its receiving antenna angle 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 aimed at the target satellite. The transmitted signal is then measured for the signal of the target satellite according to the target PCI configured on the measurement frequency point.

Exemplarily, according to the target assistance 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 all positive integers greater than or equal to 1.

For example, if the first message includes the target assistance information 11, the terminal device can determine the satellite operation data 1 corresponding to the target assistance information 11 according to the second association relationship, and then determine the measurement frequency according to the third association relationship. Satellite operation data 1 of the target satellite associated with the target PCI 11 configured on point 1. 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 geographic location 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 on it.

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 correlation shown in Table 5, when the target satellite is measured, for each measurement frequency point, the target PCI can be determined only after blindly trying up to 1008 kinds of PCI information. 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 points through the blind trial process. The spatial scanning process of the directional antenna is independent of the measurement frequency point and the PCI determination process. Regardless of whether the target auxiliary information configured on the network side is only associated with the measurement frequency point or is associated with the configured measurement frequency point and PCI information at the same time, the target auxiliary information can improve the terminal orientation.

The satellite operation data of the target satellite, the fifth association relationship is used to indicate the association relationship between the handover configuration information and the target assistance information, the second association relationship is used to indicate the association relationship between the assistance information and the satellite operation data, and then according to The satellite operation data of the target satellite and the geographic location information of the terminal equipment are used to adjust the antenna angle.

Specifically, the second association relationship may be pre-stored in the terminal device, and the association relationship is used to represent the corresponding relationship between the plurality of auxiliary information and the plurality of satellite operation data, and there is a relationship between the auxiliary information and the satellite operation data. a corresponding relationship. For example, auxiliary information 1 corresponds to satellite operation data 1, auxiliary information 2 corresponds to satellite operation data 2... Auxiliary information P corresponds to satellite operation data P.
