[0002] Although 5G has already been commercially used, it cannot guarantee network coverage in remote ocean and land areas due to geographical conditions and business models. To break through the topographical limitations, satellite communication and terrestrial networks are integrated to form a global seamless coverage of air, space, and land integrated stereoscopic network, which has become a research hotspot in the current academic and industrial circles. International organizations such as 3GPP and ITU have also established corresponding working groups to conduct standardization research on satellite-terrestrial integration. The Non-Terrestrial Network (NTN) of 3GPP is committed to integrating satellite communication with 5G, solving the key problems of New Radio (NR) supporting NTN, and laying a technical foundation for 6G satellite-terrestrial integration research. The future air-space-ground integrated network mainly focuses on deep integration, combining multiple communication platforms to provide more extensive and diversified communication services.

[0003] However, in existing technical research, the access network equipment in the non-terrestrial network, such as the Non-GeoStationary Orbit (NGSO) satellite and the Low Earth Orbit (LEO) satellite in the satellite, has a very large coverage range, which can reach hundreds of square kilometers. However, different areas within the coverage range may require different services. Since the user equipment (UE) does not know the service area corresponding to the MBS service, the UE may not be interested in the MBS service, consider the MBS service to be unimportant or have a low priority, or be unable to enter a suitable cell to receive the MBS service, etc., resulting in MBS service packet loss, interruption, or reception failure, affecting the reliability of the MBS service.

[0033] The present application will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0034] Before any examples of example embodiments are described in detail, it is to be understood that the example embodiments are not limited in their application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. Examples of example embodiments are described and explained as contemplated by the inventor(s).

[0035] Furthermore, embodiments and features of embodiments in this application can be combined with each other as much as is possible, without mutual conflicts.

[0036] The MBS service includes broadcast service, groupcast service and multicast service. Taking the multicast service as an example, the multicast service can be transmitted in a point-to-multipoint (PTM) manner, which has the characteristic of transmitting data at a lower data code rate. The network node can transmit the MBS service to multiple UEs, which is more beneficial to save network resources in the case of a large number of receiving UEs.

[0037] In the prior art, the coverage of the access network device in the non-terrestrial network is very large, but different areas within the coverage may need to transmit different services. Since the UE does not know the service area corresponding to a certain or certain MBS service, it may not be interested in, consider unimportant or have a lower priority, or be unable to enter a suitable cell to receive the MBS service, etc. MBS service packet loss, interruption or failure to receive, affecting the reliability of the MBS service.

[0038] An example application scenario is: for two MBS services MBS1 and MBS2 in the communication system, the UE only knows the service area of MBS1 and does not know the service area of MBS2, and may only be interested in MBS1 and not interested in MBS2, and will not receive MBS2. But if MBS2 is actually expected to be received, this scenario will result in MBS service reception failure.

[0039] Another example application scenario is: for two MBS services MBS1 and MBS2 in the communication system, the UE only knows the service area of MBS1 and does not know the service area of MBS2, and may prefer to receive MBS1, consider MBS2 unimportant or have a lower priority, and will not prefer to receive or will not receive MBS2 as soon as possible. But if MBS2 is actually more important or has a higher priority, this scenario will result in MBS service packet loss, interruption or reception failure.

[0040] Another example application scenario is that for an MBS service in a communication system, the UE does not know the service area of the MBS service, if the UE is interested in the MBS service, or the MBS service is expected to be received, or the MBS service is important or has a high priority, but the UE cannot enter the correct cell and service area to receive the MBS service, and cannot determine the target cell that can receive the MBS service in the cell reselection process, which will also cause the MBS service to be lost, interrupted, or failed to be received.

[0041] Another example application scenario is that in a communication system, there are three cells Cell1, Cell2 and Cell3, for an MBS service, Cell1 does not support receiving the MBS service, Cell2 and Cell3 support receiving the MBS service, and the UE can immediately or quickly reach the service area of the MBS service after entering Cell2, and will not immediately or will take a long time to reach the service area of the MBS service after entering Cell3. Since the UE does not know the service area of the MBS service, the UE cannot determine the priority of the frequency corresponding to each cell, and cannot guarantee to select the target cell that can receive or quickly receive the MBS service in cell reselection, which will also cause the MBS service to be lost, interrupted, or failed to be received.

[0042] Another example application scenario is that for two MBS services MBS1 and MBS2 in a communication system, the current location or location to be in of the UE is the service area of MBS1, not the service area of MBS2, but since the UE does not know which MBS service the current location or location to be in corresponds to the service area, it cannot determine which MBS service can be received or will be received, makes a wrong decision (such as receiving MBS2), wastes unnecessary resources, and also causes the MBS service to be lost, interrupted, or failed to be received.

[0043] The present application provides a kind of indication information and its transceiving method, for MBS service, network equipment indicates the service area corresponding to MBS service to UE.On this basis, user equipment can be clear the service area of MBS service according to indication information, can provide basis for determining whether to receive MBS service, receive MBS service in which cell, receive which MBS service, determine the priority of the frequency of cell and / or how to determine the target cell of cell reselection, etc., improve the reliability of MBS service.

[0044] The user equipment (UE) in the embodiments of the present application can be referred to as a terminal, which can be a mobile terminal, a vehicle-mounted terminal, etc. The UE includes all devices that provide voice and / or data connectivity to users, such as wireless terminal devices, mobile terminal devices, device-to-device communication (D2D) terminal devices, vehicle-to-everything (V2X) terminal devices, machine-to-machine / Machine-type Communications (M2M / MTC) terminal devices, Internet of Things (IoT) terminal devices, light terminal devices (Light UE), reduced capability user equipment (REDCAP UE), subscriber units, subscriber stations, mobile stations, remote stations, access points (APs), remote terminals, access terminals, user terminals, user agents, or user devices, etc., and can also be a user equipment in future communication systems. The present patent does not limit this.

[0045] The network device in the embodiments of the present application can be an access network device, a core network device, or a server, etc. The access network device can be a base station in a terrestrial communication network, and can also be a base station in an NTN network. For example, an evolved NodeB (eNB), a next-generation Node (gNB) in an NR system, a road side unit (RSU), and can also be a centralized unit (CU) and a distributed unit (DU) in a cloud access network system, and can also be an access network device in a future communication system. The core network device can be a mobility management device (MME), a serving gateway (SGW), a packet data node gateway (PGW), a home subscriber server (HSS) storing user subscription information, a policy control unit (PCRF), etc., and can also be a core network device in a future communication system. The present application does not limit this.

[0046] FIG. 1 is a flowchart of a service area indication method provided by an embodiment of the present application. The embodiment can be applied to the case of sending indication information. Specifically, the service area indication method can be executed by a service area indication apparatus, which can be implemented in software and / or hardware and integrated in a network device.

[0047] As shown in FIG. 1, the sending method provided by an embodiment of the present application can include the following steps:

[0048] S110, generating indication information, the indication information being used to indicate a service area of an MBS service;

[0049] S120, sending the indication information to a terminal.

[0050] In the embodiment, the service area can include an area covered by the sending apparatus under NTN network connection, or an area in an NTN cell covered by the sending apparatus under NTN network connection. The service area in the NTN cell can be one or multiple.

[0051] By introducing the indication information, the correspondence between the MBS service and the service area is indicated, and in multiple services and multiple areas, the UE can be explicitly informed of which MBS service(s) can be received in which service area through the content indicated by the indication information. For example, at least one MBS service and the service area corresponding to each MBS service are indicated; for another example, at least one service area and the MBS service corresponding to each service area are indicated. Thus, the UE can be explicitly informed of the service area of the MBS service under the NTN communication scenario.

[0052] In an exemplary application scenario, for a communication system: there is a cell Cell1, the cell Cell1 supports two MBS services: MBS1 and MBS2, if the UE is interested in MBS1, the UE can obtain the service area Area1 corresponding to MBS1 according to the indication information, and then receive MBS1 in the corresponding service area Area1, thereby avoiding the failure of receiving the interested MBS service.

[0053] In another exemplary application scenario, for two MBS services: MBS1 and MBS2 in a communication system, the UE can know the service area corresponding to each of MBS1 and MBS2 according to the indication information, and can comprehensively consider to decide which MBS service to receive preferentially, determine which MBS service is important or has a higher priority, and avoid the important or higher-priority MBS service from being dropped, interrupted, or failed to be received.

[0054] In another exemplary application scenario: for an MBS service in a communication system, a UE can know the service area of the MBS service according to the indication information, and if the UE is interested in the MBS service, or the MBS service is expected to be received, or the MBS service is important or has high priority, etc., the UE can enter a correct cell and service area to receive the MBS service, or can determine a target cell that can receive the MBS service in the cell reselection process, so as to avoid MBS service packet loss, interruption or reception failure.

[0055] In another exemplary application scenario: there are three cells Cell1, Cell2 and Cell3 in a communication system, for an MBS service, Cell1 does not support receiving the MBS service, Cell2 and Cell3 support receiving the MBS service, and a UE can immediately or quickly reach the service area of the MBS service after entering Cell2, and will not immediately or will take a long time to reach the service area of the MBS service after entering Cell3. The UE can know the service area of the MBS service according to the indication information, and accordingly can determine the priority of the frequency corresponding to each cell, for example, the frequencies corresponding to each cell in descending order of priority are: the frequency corresponding to Cell2, the frequency corresponding to Cell3, and the frequency corresponding to Cell1; in cell reselection, a target cell (such as Cell2 or Cell3) that can receive or quickly receive the MBS service can be selected, so as to avoid MBS service packet loss, interruption or reception failure.

[0056] In another exemplary application scenario: for two MBS services MBS1 and MBS2 in a communication system, if a UE knows according to the indication information that the current or future location is the service area of MBS1, the UE can correctly receive MBS1 in the service area and will not receive MBS2, so as to avoid wasting unnecessary resources, and also to avoid MBS service packet loss, interruption or reception failure.

[0057] The service area indication method of the embodiment can effectively indicate the service area of an MBS service to a user equipment, so that the user equipment can know the service area of the MBS service according to the indication information, and can provide a basis for determining whether to receive the MBS service, in which cell to receive the MBS service, determining the priority of the frequency of the cell or how to determine the target cell of cell reselection, etc., and improve the reliability of the MBS service.

[0058] It should be noted that there can be one or more MBS services in the communication system, and the indication information can be information concept for one MBS service. For example, one indication information indicates the service area information corresponding to one MBS service, and the communication system can include multiple indication information. Alternatively, the indication information can also be a collection of information for all MBS services and their service areas.

[0059] In an embodiment, the sending device that sends the indication information can be a base station in the NTN network, including a transmittal type base station, a regenerate type base station, and other types of base stations. The base station can be loaded on a non-ground or air device, for example, can be located on a satellite, space station or other aircraft.

[0060] In an embodiment, the indication information includes service information of the MBS service and service area information of the MBS service; the service area information includes area identifier and / or area geographical position information.

[0061] Specifically, the service information of the MBS service is used to indicate a specific MBS service, mainly including service identifier. Optionally, the service information can also include service type and service priority, etc. The service area information is used to indicate a specific service area, for example, including area identifier of the service area. The area identifier can include area ID (Cell ID) and area index (Cell Index). The service area information can also include area geographical position information, which can be used to describe the shape, size and / or geographical position of the service area. On this basis, the UE can determine the specific location of the service area of the MBS service.

[0062] Taking the example of service information including service identifier and service area information including area identifier, the current communication system includes two areas: Area1 and Area2, and two different MBS services: MBS1 and MBS2. The service area corresponding to MBS1 is Area1 and Area2, and the service area corresponding to MBS2 is Area1. For MBS1, the area identifiers of Area1 and Area2 can be used to represent that the service area corresponding to MBS1 includes Area1 and Area2. For MBS2, the area identifier of Area1 can be used to represent that the service area corresponding to MBS2 includes Area1. For Area1, the service identifiers of MBS1 and MBS2 can be used to represent that the service areas corresponding to MBS1 and MBS2 both include Area1. For Area2, the service identifier of MBS1 can be used to represent that the service area corresponding to MBS1 includes Area2.

[0063] In an embodiment, the area geographical position information includes at least one of the following:

[0064] Circular region information, including: reference location information and / or radius:

[0065] Polygonal region information, including: shape and / or latitude and longitude of vertex and / or boundary line position information.

[0066] In this embodiment, the region geographical position information can be used to indicate the actual coverage of the service area. The region geographical position information can include circular region information, and / or polygonal region information, and / or other types of region information.

[0067] As an example, the service area can be a circular region, and the corresponding region geographical position information can include reference location information and / or radius of the circular region. The reference location information can be the position or latitude and longitude coordinates of the center of the circle, etc.

[0068] As an example, the service area can be a polygonal region, and the corresponding region geographical position information can include shape (such as the number of sides and / or side length of the polygon, etc.) of the polygonal region, latitude and longitude of the vertex of the polygonal region, and / or boundary line position information (such as the direction of the side, the position or latitude and longitude coordinates of the end point or midpoint of each side, etc.).

[0069] In an embodiment, the service information includes at least one of the following:

[0070] Session identifier, group radio network temporary identity (G-RNTI), temporary mobile group identity (TMGI).

[0071] In an embodiment, the indication information is used to indicate at least one MBS service, and the service area corresponding to each MBS service. Wherein, a single MBS service can correspond to one or more service areas. The service areas corresponding to different MBS services can be the same or different, or partially the same.

[0072] As an example, there are three MBS services in the communication system: MBS1, MBS2 and MBS3. The indication information can indicate the following: the service area corresponding to MBS1 is Area1, the service area corresponding to MBS2 is Area2 and Area3, and the service area corresponding to MBS3 is Area3.

[0073] Specifically, the indication information can include an MBS service list, which is used to indicate at least one MBS service, and the service area corresponding to each MBS service. For example, the MBS service list is in the following form:

[0074] • MBS1

[0075] Area1

[0076] • MBS2

[0077] Area2, Area3

[0078] • MBS3

[0079] Area3

[0080] In an embodiment, the indication information is used to indicate at least one service area, and the MBS service corresponding to each service area. Wherein, a single service area can correspond to one or more MBS services. The MBS services corresponding to different service areas can be the same or different, or partially the same.

[0081] As an example, there are three service areas in the communication system: Area1, Area2 and Area3, the indication information can indicate the following contents: the MBS service corresponding to Area1 is MBS1, the MBS service corresponding to Area2 is MBS2, and the MBS service corresponding to Area3 is MBS2 and MBS3.

[0082] Specifically, the indication information can include a service area list, which is used to indicate at least one service area, and the MBS service corresponding to each service area. For example, the service area list is in the following form:

[0083] • Area1

[0084] MBS1

[0085] • Area2

[0086] MBS2

[0087] • Area3

[0088] MBS2, MBS3

[0089] In an embodiment, the MBS service includes: the MBS service supported by the current cell and / or not supported by the current cell; and / or, the MBS service supported by the current frequency and / or not supported by the current frequency.

[0090] Wherein, the current frequency can be the frequency corresponding to the current cell where the UE is located. Generally, the frequency of the current cell and the frequency of the neighboring cell are different, and the frequency of the current cell and the non-adjacent cell can be the same or different. The MBS services supported by the current cell and the neighboring cell can be the same or different or partially the same, and the MBS services supported by the current cell and the non-adjacent cell with the same frequency can be the same or different or partially the same.

[0091] The neighbor cell can refer to a cell that has an overlap, a tangent or a common border with the current cell, can refer to a cell that is within a set range from the current cell, can refer to a candidate cell for cell reselection, or can refer to a cell indicated in a neighbor cell list (NeighbourCellList), and the cell indicated in the neighbor cell list can be a neighbor cell that can support the MBS service provided by the current cell.

[0092] As shown in FIG. 2, a cell where the UE is currently located is Cell0, and the corresponding frequency is f0. Cell1 is a neighbor cell of Cell0, and the corresponding frequency is f1. Cell2 and Cell3 are cells that are not adjacent to Cell0, and the corresponding frequencies are f2 and f3, respectively. f0≠f1, f2=f0, and f3≠f0. There are 10 MBS services MBS1-MBS10 in the current communication system. Cell0 supports MBS1-MBS5, Cell1 supports MBS3-MBS6, Cell2 supports MBS5-MBS8, and Cell3 supports MBS6, MBS9 and MBS10. 10 10 In this case, the MBS service can include at least one of the following:

[0093] MBS services supported by the current cell, i.e., MBS1-MBS5;

[0094] MBS services not supported by the current cell, i.e., MBS6-MBS 10 ;

[0095] MBS services supported by the current frequency, i.e., MBS1-MBS8;

[0096] MBS services not supported by the current frequency, i.e., MBS9, MBS 10 .

[0097] It is worth noting that the MBS services supported by the current frequency can include the MBS services supported by the current cell (MBS1-MBS5) and can also include the MBS services supported by the non-adjacent cell of the same frequency (MBS6-MBS8 supported by Cell2).

[0098] In an embodiment, the MBS service includes at least one of the following MBS services:

[0099] MBS services not supported by the current cell;

[0100] MBS services supported by a neighbor cell of the current cell;

[0101] MBS services supported by a neighbor cell of the current cell and not supported by the current cell.

[0102] ​Normally, a UE can only obtain information about MBS services supported by the current cell, and cannot obtain information about MBS services not supported by the current cell. However, in this embodiment, MBS services may include MBS services not supported by the current cell. MBS services not supported by the current cell may be supported by neighboring cells, or they may not be supported by neighboring cells.

[0103] For example, there are currently 10 MBS services in the communication system: MBS1 to MBS2. 10 If the current cell is Cell0, frequency f0, and supports MBS1 to MBS5; and the neighboring cell is Cell1, frequency f1, and supports MBS3 to MBS6; and f0 ≠ f1, then the MBS service indicated by the indication information may include all or part of at least one of the following MBS services:

[0104] The current cell does not support MBS6 to MBS. 10 ;

[0105] The neighboring cells support MBS3 to MBS6;

[0106] Neighboring cells support features that the current cell does not, namely MBS6.

[0107] Based on this, the UE can clearly identify the service area of ​​MBS services that are not supported by the current cell according to the indication information. Even if the MBS service is not supported by the current cell, it can still be a service that the UE is interested in or can be received. Therefore, when determining whether to receive a certain MBS service, in which cell to receive the MBS service, which MBS service to receive, the frequency priority of the cell, and / or the target cell for cell reselection, there is sufficient basis and more comprehensive choices, thereby improving the reliability of MBS services.

[0108] The MBS service includes at least one of the following MBS services:

[0109] MBS services not supported by the current frequency;

[0110] MBS services supported by different frequencies;

[0111] MBS services that are supported at different frequencies but not currently supported at the current frequency.

[0112] Normally, a UE can only obtain information about MBS services supported by the current frequency, and cannot obtain information about MBS services not supported by the current frequency. However, in this embodiment, MBS services may include MBS services not supported by the current frequency. MBS services not supported by the current frequency may be supported by other frequencies, or they may be not supported by other frequencies.

[0113] Here, "different frequency" can refer to a frequency that is different from the current frequency.

[0114] The inter-frequency can also be determined by the network device or indicated by a system message.

[0115] The inter-frequency can include a frequency of a neighbor cell, etc.

[0116] For example, there are 10 MBS services MBS1-MBS10 in the current communication system. 10 The current cell is Cell0, the frequency is f0, and MBS1-MBS5 are supported; the neighbor cell is Cell1, the frequency is f1, and MBS3-MBS6 are supported; the inter-frequency cell is Cell2, the frequency is f2, and MBS5-MBS8 are supported; f0≠f1, f0≠f2, and the MBS services indicated by the indication information can include all or part of at least one of the following MBS services:

[0117] MBS services not supported by the current frequency, i.e., MBS6-MBS8. 10 ;

[0118] MBS services supported by the inter-frequency, i.e., MBS3-MBS8.

[0119] MBS services supported by the inter-frequency and not supported by the current frequency, i.e., MBS6-MBS8.

[0120] On this basis, the UE can determine the service area of the MBS service not supported by the current frequency according to the indication information, and even if the MBS service not supported by the current frequency, it can also be a service of interest to the UE or can be received, so that there is sufficient basis and more comprehensive selection in the case of determining whether to receive a certain MBS service, receiving an MBS service in which cell, receiving which MBS service, determining the priority of the frequency of the cell, and / or determining the target cell of cell reselection, etc., thereby improving the reliability of the MBS service.

[0121] In an embodiment, all or part of the indication information is carried by an MBS control channel (MCCH).

[0122] Specifically, the indication information can include multiple information, and accordingly, all information in the indication information can be carried by the MCCH, and part of the information in the indication information can be carried by the MCCH.

On this basis, according to the indication information, the service area of the MBS service can be determined, so that the target cell is entered through the cell reselection process to receive the MBS service.

[0203] According to the indication information, the priority of the frequency of the cell can also be determined, for example, the priority of the frequency of the cell containing the service area (which can contain all or part of the service area) is higher, and the priority of the frequency of the cell not containing the service area is lower; or the priority of the frequency of the cell covered by the service area (which can be all or part of the covered cell) is higher, and the priority of the frequency of the cell not covered is lower; or for example, the larger the area or proportion of the service area in a cell, the higher the priority of the frequency of the cell; or for example, the closer the distance between the service area in a cell and the current location of the UE or the current cell, the higher the priority of the frequency of the cell. The specific way of determining the priority of the frequency of the cell is not limited in this embodiment.
