Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

The UE history information includes information of a cell where a User Equipment (UE) resides, and the network device may determine a history trajectory of the UE based on the cell where the UE resides, thereby performing mobility optimization. The user equipment history information may be recorded at the UE side, or may be recorded at the network equipment side.

Since the conventional ground network cannot provide seamless coverage for the UE, especially in the sea, desert, air, and other places where the base station cannot be deployed, a Non-terrestrial network (NTN) is introduced into the 5G system, which provides seamless coverage for the UE by deploying the base station or part of the base station functions on an upper air platform or a satellite, and the upper air platform or the satellite is less affected by natural disasters, so that the reliability of the 5G system can be improved.

However, the coverage area of a satellite cell is large, much higher than the cell diameter of a conventional terrestrial cell. Therefore, if the UE resides in the satellite cell, the residence time is generally long, and the network device, especially the terrestrial network device, cannot determine the motion trajectory of the UE based on the history information of the user equipment, so that mobility optimization cannot be performed. For example, for a geostationary-earth orbit (GEO) satellite, the cell diameter of a GEO satellite cell is typically 500km, which is much higher than the cell diameter of a conventional terrestrial cell. If the UE resides in the GEO cell, the residence time is generally long, and therefore the network device, especially the terrestrial network device, cannot determine the motion trajectory of the UE based on the history information of the user equipment.

Furthermore, the network device may be other means for providing wireless communication functionality for the terminal device, where possible. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices. For convenience of description, in the embodiments of the present application, an apparatus for providing a wireless communication function for a terminal device is referred to as a network device.

The terminal device may be a wireless terminal device capable of receiving network device scheduling and indication information, and the wireless terminal device may be a device providing voice and/or data connectivity to a user, or a handheld device having a wireless connection function, or other processing device connected to a wireless modem. Wireless terminal devices, which may be mobile terminal devices such as mobile telephones (or "cellular" telephones), computers, and data cards, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks or the internet via a radio access network (e.g., a RAN). For example, devices such as Personal Communication Services (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), tablet computers (pads), and computers with wireless transceiving functions.

In addition, the embodiment of the application can also be applied to other communication technologies facing the future. The network architecture and the service scenario described in this application are for more clearly illustrating the technical solution of this application, and do not constitute a limitation to the technical solution provided in this application, and it can be known by those skilled in the art that the technical solution provided in this application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of new service scenarios.

The embodiments of the present application may be applied to the fourth generation mobile communication system (4G) system, 5G system, NTN system, or future mobile communication system.

As one possible application scenario, the NTN system may include a satellite system. Satellite systems can be classified into High Elliptic Orbit (HEO) satellites, high orbit (GEO) satellites, medium orbit (MEO) satellites, and low-orbit (LEO) satellites according to satellite altitude, i.e., satellite orbital altitude. In addition, the NTN system may also include a High Altitude Platform (HAPS) communication system.

As an example, a mechanism for providing coverage cells by GEO satellites and LEO satellites is briefly described as follows.

1. GEO satellite: also called stationary satellites, the speed of movement of the satellite is the same as that of the autorotation system of the earth, so that the satellite remains stationary with respect to the ground, and correspondingly, the cell of the GEO satellite is stationary. The coverage area of the GEO satellite cell is large, and the diameter of the cell is 500km generally.

As shown in fig. 1, the mapping method of the terrestrial stationary cells means that the locations of the cells are stationary on the ground, and the moving satellite forms the cells by adjusting its own beam. For example, time T1: cell 1 and cell 2 are covered by beams of gNB1, cell 3 and cell 4 are covered by beams of gNB 2; time T2: although both the gNB1 and the gNB2 move to the left, their beams can be adjusted to ensure the coverage of the cell 1, the cell 2, the cell 3, and the cell 4; time T3: compared to time T1, when gNB1 and gNB2 have moved far enough, gNB1 cannot provide coverage for cell 2 again by adjusting the beam, and gNB2 cannot provide coverage for cell 4 by adjusting the beam, at which time, gNB2 may provide coverage for cell 2, and gNB3 may provide coverage for cell 4.

2. LEO satellite: the satellite moves relatively fast, about 7Km/s, relative to the ground, and so the coverage area serviced by the LEO satellite moves.

As shown in fig. 2, the mapping method of the terrestrial mobile cell means that the moving satellite does not dynamically adjust its beam direction, and the beam generated by the moving satellite moves terrestrially as the satellite moves. For example, the following steps are carried out: time T1: the area shown in fig. 2 is covered by cell 1, cell 2, cell 3, and cell 4 of gNB1 and gNB2, and at time T3, the area is covered by cell 2, cell 3, cell 4, and cell 5 of gNB1, gNB2, and gNB 3.

In the NTN system, the architecture of satellite communication is divided into two major categories, one is a transparent forwarding (transparent) architecture, and at this time, the satellite only performs relay (relay) or amplifier, and may perform radio frequency filtering, amplification, etc., to regenerate the signal, as shown in fig. 3; the second is a regenerative architecture, where the satellite may be configured as a gNB (as shown in fig. 4 and 5), a Distributed Unit (DU) (as shown in fig. 6), and a relay, where the relay is different from the relay in the first class, and is no longer a simple relay, and has a signal processing function, similar to an Integrated Access and Backhaul (IAB) node or other relay nodes. When the satellite is used as a gNB, DU, IAB or other relay node, the function of the satellite is similar to that of a common gNB, DU, IAB or other relay node.

The NTN communication system provides seamless coverage for the terminal equipment by deploying the functions of the access network equipment or part of the access network equipment on non-ground equipment (such as a high-altitude platform or a satellite), and the reliability of the communication system can be improved because the non-ground equipment is less affected by natural disasters. For convenience of explanation and understanding of the solution of the embodiment of the present application, the NTN communication system in which the network device is deployed on a satellite will be described as an example in the following. Moreover, for convenience of description, the following description will use "satellite" instead of "network device on satellite". That is, the communication between the terminal device and the satellite referred to in the following of the present application actually refers to the communication between the terminal device and the network device on the satellite. The description is unified here and will not be repeated later.

In the 5G system, Radio Resource Control (RRC) states of the UE include a CONNECTED state (RRC _ CONNECTED), a deactivated state (RRC _ INACTIVE), and an IDLE state (RRC _ IDLE), and the transition between the three states is shown in fig. 7. Illustratively, when the UE is in the RRC _ CONNECTED state, the UE establishes links with both the network device and the core network device, and when data arrives at the network, the data can be directly transmitted to the UE. When the UE is in the RRC _ INACTIVE state, it indicates that the UE has previously established a link with the network device and the core network device, but the link from the UE to the network device is released, and although the link is released, the UE and the network device store the context of the UE, and when there is data to be transmitted, the network device can quickly recover the link; in general, the source network device (or anchor network device) may be understood as a network device that stores a context of the UE and/or the source network device may be a network device that generates a configuration for the UE to enter an RRC _ INACTIVE state. When the UE is in the RRC _ IDLE state, there is no link between the UE and the network device and the core network device, and when there is data to be transmitted, a link between the UE and the network device and the core network device needs to be established.

In the prior art, the UE history information recorded on the UE side may include information of all cells accessed by the UE and information of residence time of each cell. Here, the cell may include at least one of a cell where the UE is camped in an idle state, a cell where the UE is camped in a deactivated state, or a cell where the UE is connected in a connected state. Since the network device side can only perceive the UE in the connected state, the UE history information recorded by the network device side may include cell information and corresponding residence time information when the UE is in the connected state. In addition, the user equipment history information recorded on the network equipment side may further include a cell type, a handover reason, and the like. Wherein, the cell information may include: at least one of a Cell Global Identifier (CGI), a Physical Cell Identifier (PCI), and a cell frequency. Based on this, when the coverage area of the satellite cell is large, the network device cannot determine the motion trajectory of the UE based on the history information of the user equipment, so that mobility optimization cannot be performed.

Example 1:

the embodiment of the application provides a method for determining the area of a terminal device in a serving cell, which is used for determining the area of the terminal device in the serving cell. As shown in fig. 8, the method includes:

s801: the first network device determines at least two areas comprised by the first cell.

In one possible implementation, the at least two areas constitute a coverage area of the first cell, that is, the coverage area of the first cell may include at least two areas. As shown in fig. 9(a), the solid line indicates the coverage area of the first cell, the dotted line indicates the boundary of the area included in the first cell, and the first cell includes 4 areas, i.e., area 1, area 2, area 3, and area 4.

In another possible implementation, the at least two areas may include a coverage area of the first cell, that is, the area coverage of the at least two areas may be larger than the coverage area of the first cell. As shown in fig. 9(b), the area formed by the solid line indicates the coverage area of the first cell, and the 4 areas formed by the broken line indicate 4 areas including area 1, area 2, area 3, and area 4, and the area range of the 4 areas is larger than the coverage area of the first cell.

It should be noted that fig. 9(a) and 9(b) are only schematic diagrams of a plurality of areas included in the first cell, and in practical applications, the plurality of areas included in the first cell may also have other forms, for example, the first cell includes a plurality of circular areas, as shown in fig. 9(c), which is not specifically limited in this embodiment of the present application.

The first cell is any one of one or more cells under the first network device. The first cell may be an NTN cell or a TN cell. The at least two areas are logically virtual areas, and the sizes of the at least two areas may be the same or different. The area coverage of each of the at least two areas may be non-overlapping with other areas or there may be overlapping areas, but the area coverage of one area may not completely cover the area coverage of another area.

S802: the first network device sends configuration information to the terminal device. Accordingly, the terminal device receives configuration information from the first network device.

Wherein the configuration information indicates configuration information of the at least two areas.

Wherein the terminal device resides in the first cell, and therefore the first cell can be understood as the current serving cell of the terminal device.

Optionally, the first network device may send the configuration information to all terminal devices residing in the first cell through a broadcast message; or, the configuration information may be sent separately to the terminal device residing in the first cell through a unicast message; alternatively, the configuration information may be sent to a group of terminal devices residing in the first cell through a multicast message, which is not specifically limited in this embodiment of the present application.

Optionally, the first network device may carry the configuration information in a system message to send, or may carry the configuration information in a dedicated RRC message to send, which is not specifically limited in this embodiment of the present application.

Optionally, in different implementation manners of the embodiment of the present application, the content of the configuration information may also be different:

in one possible implementation, the configuration information may include: a center position coordinate of each of the at least two regions, a region radius of each region; alternatively, the configuration information may include: the center position coordinates of each of the at least two regions, the region radius of each region, and the region identification of each region.

For example, assuming that the first cell under the first network device includes 2 areas, and the configuration information includes a center position coordinate 1 and an area radius of each of the at least two areas, the configuration information may be { center position coordinate 1, area radius 1}, { center position coordinate 2, area radius 2 }; or, when the configuration information includes the center position coordinate, the area radius, and the area identifier of each of the at least two areas, the configuration information may be { area 1, center position coordinate 1, area radius 1}, { area 2, center position coordinate 2, area radius 2 }. Optionally, the configuration information may directly indicate an area identifier of each area, for example, the configuration information is { area 1, center position coordinate 1, area radius 1 }; or, the area identifier of each area may also be indirectly indicated, for example, the order of the areas in the configuration information is the area identifiers of the areas, for example, { center position coordinate 1, area radius 1} is the 1 st area information in the configuration information, and may correspond to area 1, and { center position coordinate 2, area radius 2} is the 2 nd area information in the configuration information, and may correspond to area 2.

In one possible implementation, the configuration information may include: a center position coordinate for each of the at least two zones, a zone radius for each zone, a user-readable name for each zone; or the configuration information may include: a user-readable name for each of the at least two regions. Wherein the user-readable name of each region may reflect the region extent of the region.

For example, if the first cell under the first network device includes 2 areas, the area range with the center position coordinate of the 1 st area as the center of the circle and the area radius of the 1 st area as the radius is shanghai huangpu area, the user-readable name of the 1 st area may be shanghai huangpu area; the 2 nd area may be a shanghai xu-hui area if the area range with the area radius of the 2 nd area as the radius is the shanghai xu-hui area, and the user-readable name of the 2 nd area may be the shanghai xu-hui area. Alternatively, the user-readable name of each region may reflect a location in the region. For example, if the 1 st region is Shanghai Huangpu district, the user-readable name of the 1 st region can be a landmark building name of the Shanghai Huangpu district. It should be noted that, when the first network device determines the at least two areas, it needs to specify the area range of each area (for example, the center position coordinate and the area radius of each area), but in the configuration information, only the user-readable name of each area in the at least two areas may be carried.

The center position coordinates of each region are different, and the region radius of each region may be the same or different.

In another possible implementation, the configuration information may include a length and a width of each of the at least two regions, a total number of regions in a longitude line direction, and a total number of regions in a latitude line direction.

The first area is an area where the terminal device is currently located in the at least two areas.

In a possible implementation manner, if the terminal device has a positioning function, the determining, by the terminal device, the first area according to the configuration information may be: the terminal equipment acquires the position information of the terminal equipment and determines a first area according to the position information and the configuration information of the terminal equipment.

Optionally, in this possible implementation manner, according to the difference in the configuration information, the terminal device determines the first area in a different manner according to the location information and the configuration information of the terminal device. Illustratively, there may be two ways:

the first method is as follows: the configuration information includes a center position coordinate of each of the at least two regions and a region radius of each region. In addition, the configuration information may also include a zone identification for each zone or a user-readable name for each zone.

In this manner, the location information of the terminal device acquired by the terminal device may be a location coordinate of a current geographic location of the terminal device. The terminal equipment determines the first area according to the position information and the configuration information of the terminal equipment. Illustratively, the terminal device respectively calculates a linear distance corresponding to the terminal device and each area, and then compares each linear distance with the area radius of the corresponding area; and if the certain straight-line distance is smaller than the area radius of the corresponding area, determining the area as a first area.

For example, assuming that a first cell under a first network device includes 2 areas, the configuration information includes { center position coordinate 1, area radius 1}, { center position coordinate 2, area radius 2}, the position coordinate of the current geographic position of the terminal device is position coordinate 0, the straight-line distance between the center position coordinate 1 and the position coordinate 0 calculated by the terminal device is distance 1, the straight-line distance between the center position coordinate 2 and the position coordinate 0 is distance 2, and if the distance 1 is greater than the area radius 1 and the distance 2 is less than the area radius 2, the terminal device determines an area corresponding to the { center position coordinate 2, area radius 2} as the first area; or, if the distance 1 is smaller than the area radius 1 and the distance 2 is larger than the area radius 2, the terminal device determines the area corresponding to the { center position coordinate 1, area radius 1} as the first area. If the distance 1 is smaller than the area radius 1 and the distance 2 is also smaller than the area radius 2, the terminal device calculates a difference between the distance 1 and the area radius 1 and a difference between the distance 2 and the area radius 2, and if the difference between the distance 1 and the area radius 1 is smaller than the difference between the distance 2 and the area radius 2, the terminal device determines an area corresponding to the { center position coordinate 1, the area radius 1} as the first area.

And the configuration information comprises the length of each of the at least two regions, the width of each region, the total number of regions in the longitude line direction and the total number of regions in the latitude line direction.

In the embodiment of the present application, the length and the width of different regions in at least two regions are the same as an example.

Optionally, the configuration information may further include a region identifier of each sub-region.

In the second mode, the location information of the terminal device acquired by the terminal device may be a location coordinate (x, y) of a current geographic location of the terminal device. Wherein, x is the distance of the terminal device from the longitude direction of the relative reference point of the position system adopted by the terminal device, and y is the distance of the terminal device from the latitude direction of the relative reference point of the position system.

Optionally, the location system adopted by the terminal device may be, for example, a Global Positioning System (GPS), or may be a beidou satellite system, or may be another positioning system; the relative reference point of the position system may be different according to the position system, and may be (0, 0) or the like, which is not specifically limited in this embodiment of the present application.

In the second mode: the terminal device determines the first area according to the location information and the configuration information of the terminal device, and the determining may be: the terminal equipment determines the position of the terminal equipment in the longitude direction according to the distance in the longitude direction, the length of each area and the total number of the areas in the longitude direction; determining the position of the terminal equipment in the latitude direction according to the distance in the latitude direction, the width of each region and the total number of the regions in the latitude line direction; and then determining an area identifier according to the position in the longitude direction and the position in the latitude direction, wherein the area identified by the area identifier is the first area.

Alternatively, the position of the terminal device in the longitudinal direction may satisfy the following formula (1):

the position of the terminal device in the latitudinal direction may satisfy the following formula (2):

the region identification may satisfy the following formula (3):

zone_id＝y ₁*Nx+x ₁ (3)；

wherein, x is the distance of the terminal device from the longitude direction of the relative reference point of the position system adopted by the terminal device, y is the distance of the terminal device from the latitude direction of the relative reference point of the position system, and L is eachThe length of each region, W is the width of each region, Nx is the total number of regions in the longitudinal direction, Ny is the total number of regions in the latitudinal direction, x₁For the position, y, of the terminal device in the longitudinal direction₁Zone _ id is the area identifier and symbol determined by the terminal equipment for the position of the terminal equipment in the latitude direction

Indicating rounding down and the sign% indicates a remainder.

Illustratively, taking the current geographic location coordinate of the terminal device as (500 ), the total number of areas in the longitude line direction and the latitude line direction as 4 (i.e. the first cell includes 16 areas), and the length and width of each area are 200, the terminal device may determine x according to the above formula (1)₁Y is determined according to the above formula (2) ═ 2₁When the area identifier is determined to be 10 according to the above formula (3), the terminal device determines an area having an area identifier of 10 among the 16 areas as the first area.

It should be understood that, based on the same idea, when the first network device obtains the location information of the terminal device, the first network device may determine, based on the location information and the configuration information of the terminal device, an area where the terminal device is located in the serving cell, and specifically refer to the methods provided in the foregoing manner one and manner two, and repeated details are not repeated.

In another possible implementation manner, if the terminal device does not have a positioning function and the configuration information includes a user-readable name of each of the at least two areas, the terminal device determines the first area according to the configuration information, which may be: and the terminal equipment determines the area corresponding to the first user readable name in the configuration information as a first area. The first user readable name is a user readable name corresponding to the current geographic position of the terminal device.

Optionally, for a terminal device without a positioning function, the user may manually determine the current geographic location of the terminal device, for example, the user may carry the terminal device with him and determine the current geographic location of the user as the current geographic location of the terminal device. In addition, the terminal equipment can request a user readable name corresponding to the current geographic position of the terminal equipment from a user through the man-machine interaction interface. For example, the terminal device may display a user-readable name for each of the at least two areas on the human-computer interface, and the user (manually) selects the user-readable name corresponding to the current geographical location of the terminal device among the plurality of user-readable names.

If the user readable name of the area reflects the area range of the area, the user selects the user readable name of the area corresponding to the current geographic position of the terminal equipment; if the user-readable name of the area reflects a certain position of the area, the user selects the user-readable name corresponding to the position closest to the current geographic position of the terminal device. After the user selects the user readable name corresponding to the current geographic position, the terminal device determines the area corresponding to the user readable name as the first area.

For example, the user-readable name of the area reflects an area range of the area, the first cell under the first network device includes 3 areas, and the user-readable name of each area is { shanghai huangpu area }, { shanghai xu fu di en }, and { shanghai pu dong di en }, respectively, then the terminal device may display the user-readable names of the 3 areas on the human-computer interface, if the user determines that the terminal device is currently located in the xu fu di, the user selects the shanghai xu fu di through the human-computer interface, and then the terminal device determines the area corresponding to { shanghai xu fu di } as the first area.

For example, the user-readable name of the area reflects a certain position of the area, the first cell under the first network device includes 3 areas, the user-readable name of each area is { landmark building 1}, { landmark building 2}, and { landmark building 3}, and the landmark building 1, landmark building 2, and landmark building 3 belong to 3 areas, respectively, the terminal device may display the user-readable names of the 3 areas on the human-computer interaction interface, if the user determines that the terminal device is currently closest to the landmark building 1, the user selects the landmark building 1 through the human-computer interaction interface, and further, the terminal device determines the area corresponding to the { landmark building 1} as the first area.
