Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a service area indication method, device, network equipment, user equipment and storage medium. Background Art

[0002] Although 5G has begun commercial use, it is limited by geographical conditions and business models and cannot guarantee network coverage in remote areas of the ocean and land. In order to break through the terrain restrictions, integrating satellite communications with ground networks to form a global seamless three-dimensional network of land, sea, air, and space 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-ground integration. Among them, the non-terrestrial networks (NTN) project established by 3GPP is committed to integrating satellite communications with 5G and solving the key problem of New Radio (NR) supporting NTN. Its standardization work will lay a technical foundation for 6G satellite-ground integration research. The future integrated network of air, space, and ground will focus on deep integration, combining multiple communication platforms to provide more extensive and diversified communication services.

[0003] However, in existing technical research, since the access network equipment in non-terrestrial networks, such as non-geostationary orbit (NGSO) satellites and low earth orbit (LEO) satellites in satellites, has a very large coverage area, which can reach hundreds of square kilometers, but different areas within the coverage area may need to transmit 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 such MBS services, think that the MBS services are not important or have a low priority, or cannot enter a suitable cell to receive the MBS services, etc., resulting in MBS service packet loss, interruption or reception failure, affecting the reliability of the MBS services. Summary of the invention

[0033] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0034] It should be mentioned before discussing the exemplary embodiments in more detail that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe the steps as sequential processes, many of the steps therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0035] In addition, the embodiments in the present application and the features in the embodiments may be combined with each other if there is no conflict.

[0036] MBS services include broadcast services, groupcast services and multicast services. Taking multicast services as an example, multicast services can be transmitted in a point-to-multipoint (PTM) manner, which is characterized by data transmission at a lower data rate. Network nodes can transmit MBS services to multiple UEs, which is more conducive to saving network resources when there are a large number of receiving UEs.

[0037] In the prior art, since the coverage of access network equipment in non-terrestrial networks is very large, different areas within the coverage may require different services to be transmitted. Since the UE does not know the service area corresponding to one or some MBS services, it may not be interested in such MBS services, think that such MBS services are unimportant or have a low priority, or cannot enter a suitable cell to receive the MBS services, etc., resulting in MBS service packet loss, interruption or reception failure, affecting the reliability of the MBS services.

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

[0039] Another exemplary application scenario is: for two MBS services in a communication system: MBS1 and MBS2, the UE only knows the service area of ​​MBS1, but not the service area of ​​MBS2, and may give priority to receiving MBS1, and consider MBS2 to be unimportant or of lower priority, and will not give priority to receiving or will not receive MBS2 as soon as possible. However, if MBS2 is actually more important or has a higher priority, this scenario will cause MBS service packet loss, interruption, or reception failure.

[0040] Another exemplary application scenario is: 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 relatively important or has a higher 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 during the cell reselection process, this scenario will also cause MBS service packet loss, interruption or reception failure.

[0041] Another exemplary application scenario is: there are three cells Cell1, Cell2 and Cell3 in the communication system. For an MBS service, Cell1 does not support receiving the MBS service, Cell2 and Cell3 support receiving the MBS service, and the UE can reach the service area of ​​the MBS service immediately or quickly after entering Cell2, but will not reach the service area of ​​the MBS service immediately or after a long period of time after entering Cell3. Since the UE does not know the service area of ​​the MBS service, the UE cannot determine the priority of the frequencies corresponding to each cell, and cannot guarantee the selection of the target cell that can receive or quickly receive the MBS service during cell reselection. This scenario will also cause packet loss, interruption or reception failure of the MBS service.

[0042] Another exemplary application scenario is: for two MBS services in a communication system: MBS1 and MBS2, the UE is currently located or is about to be located in the service area of ​​MBS1, not the service area of ​​MBS2. However, since the UE does not know which MBS service corresponds to its current location or is about to be located, it cannot be determined which MBS service it can receive or is about to receive, and makes wrong decisions (such as receiving MBS2), which wastes unnecessary resources and may also cause MBS service packet loss, interruption or reception failure.

[0043] The present application provides an indication information and a method for sending and receiving the same. For MBS services, a network device indicates to a UE the service area corresponding to the MBS service. On this basis, the user equipment can clarify 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, which MBS service to receive, determining the frequency priority of the cell and / or how to determine the target cell for cell reselection, etc., thereby improving the reliability of the MBS service.

[0044] The user equipment (UE) in the embodiments of the present application may be referred to as a terminal, which may be a mobile terminal, a vehicle-mounted terminal, etc. Among them, 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 UE (REDCAP UE), subscriber unit (Subscriber Unit), subscriber station (Subscriber Station), mobile station (Mobile Station), remote station (Remote Station), access point (Access Point, AP), remote terminal (Remote Terminal), access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent), or user equipment (User Device), etc. It can also be a user device in a future communication system, which is not limited by this patent.

[0045] The network equipment in the embodiments of the present application may be an access network device, a core network device or a server, etc. The access network device may be a base station in a terrestrial communication network, or a base station in an NTN network. For example, an evolved base station eNB, a next-generation node gNB in ​​an NR system, a road side unit (RSU), or a centralized unit CU and a distributed unit DU in a cloud access network system, or an access network device in a future communication system. The core network device may be a mobility management entity (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 may also be a core network device in a future communication system, which is not limited by the present application.

[0046] Figure 1 A flowchart of a service area indication method provided in an embodiment of the present application. This embodiment is applicable to the case where indication information is sent. Specifically, the service area indication method can be executed by a service area indication device, which can be implemented by software and / or hardware and integrated in a network device.

[0047] like Figure 1 As shown, the sending method provided in the embodiment of the present application may include the following steps:

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

[0049] S120: Send the instruction information to the terminal.

[0050] In this embodiment, the service area may include an area that can be covered by the sending device under the NTN network connection, or an area in an NTN cell that can be covered by the sending device under the NTN network connection. There may be one or more service areas in the NTN cell.

[0051] By introducing indication information for indicating the correspondence between MBS services and service areas, among multiple services and multiple areas, the content indicated by the indication information can enable the UE to clearly know which service area can receive which MBS services or services. 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. In this way, the UE can clearly know the service area of ​​the MBS service in the NTN communication scenario.

[0052] In an exemplary application scenario: for a communication system: there is a cell Cell1, and 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 failure to receive the MBS service of interest.

[0053] In another exemplary application scenario: for two MBS services in a communication system: MBS1 and MBS2, the UE can know the service areas corresponding to MBS1 and MBS2 respectively according to the indication information, and can comprehensively consider and decide which MBS service to receive first, and determine which MBS service is important or has a higher priority, so as to avoid packet loss, interruption or reception failure of important or higher priority MBS services.

[0054] In another exemplary application scenario: for an MBS service in a communication system, the UE can know the service area of ​​the MBS service based on the indication information. If the UE is interested in the MBS service, or the MBS service is expected to be received, or the MBS service is more important or has a higher priority, etc., the UE can enter the correct cell and service area to receive the MBS service, or can determine the target cell that can receive the MBS service during the cell reselection process, thereby avoiding packet loss, interruption or reception failure of the MBS service.

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

[0056] In another exemplary application scenario: for two MBS services in a communication system: MBS1 and MBS2, the UE determines according to the indication information that its current location or the location to be located is the service area of ​​MBS1. Then, the UE can correctly receive MBS1 in the service area but not MBS2, thereby avoiding wasting unnecessary resources and avoiding packet loss, interruption or reception failure of MBS services.

[0057] The service area indication method of this embodiment effectively indicates the service area of ​​the MBS service to the user equipment, so that the user equipment can clarify 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, determine the frequency priority of the cell or how to determine the target cell for cell reselection, thereby improving the reliability of the MBS service.

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

[0059] In one embodiment, the sending device for sending the indication information may be a base station in the NTN network, including a transparent transmission type base station, a regenerate type base station, and other types of base stations. The base station may be mounted on a non-ground or airborne device, for example, may be located on a satellite, a space station, or other aircraft.

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

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

[0062] Taking the example that the service information includes the service identifier and the service area information includes the area identifier, the current communication system includes two areas: Area1 and Area2, and there are two different MBS services: MBS1 and MBS2. The service areas corresponding to MBS1 are Area1 and Area2, and the service area corresponding to MBS2 is Area1. For MBS1, the area identifiers of Area1 and Area2 may be used to indicate that the service areas corresponding to MBS1 are Area1 and Area2, and for MBS2, the area identifier of Area1 may be used to indicate that the service area corresponding to MBS2 is Area1; or for Area1, the service identifiers of MBS1 and MBS2 may be used to indicate that the service areas corresponding to MBS1 and MBS2 both include Area1, and for Area2, the service identifier of MBS1 may be used to indicate that the service area corresponding to MBS1 includes Area2.

[0063] In one embodiment, the regional geographic location information includes at least one of the following:

[0064] Circular area information, including: reference position information and / or radius:

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

[0066] In this embodiment, the regional geographic location information may be used to indicate the range actually covered by the service area. The regional geographic location information may include circular area information, and / or polygonal area information and / or other types of area information.

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

[0068] As an example, the business area may be a polygonal area, and the corresponding regional geographic location information may include the shape of the polygonal area (such as the number of sides and / or side lengths of the polygon, etc.), the longitude and latitude of the vertices of the polygonal area, and / or boundary line location information (such as the direction of the edge, the position or longitude and latitude coordinates of the endpoint or midpoint of each edge, etc.).

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

[0070] Session ID, Group-Radio Network Temporary Identity (G-RNTI), Temporary Mobile Group Identity (TMGI).

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

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

[0073] Specifically, the indication information may include an MBS service list, where the MBS service list is used to indicate at least one MBS service and a 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 one embodiment, the indication information is used to indicate at least one service area and the MBS service corresponding to each service area. A single service area may correspond to one or more MBS services. The MBS services corresponding to different service areas may 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, and the indication information may indicate the following: the MBS service corresponding to Area1 is MBS1, the MBS service corresponding to Area2 is MBS2, and the MBS services corresponding to Area3 are MBS2 and MBS3.

[0082] Specifically, the indication information may include a service area list, where the service area list 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] Area 1

[0084] MBS1

[0085] Area 2

[0086] MBS2

[0087] Area 3

[0088] MBS2, MBS3

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

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

[0091] Among them, the neighboring cell may refer to a cell that overlaps, is tangent to, or has a common boundary with the current cell, or may refer to a cell that is within a set range of distance from the current cell, or may refer to a candidate cell that can be used for cell reselection, or may refer to a cell indicated in a neighboring cell list (NeighbourCellList), etc. Among them, the cell indicated in the neighboring cell list may be a neighboring cell that can support the MBS service provided by the current cell.

[0092] like Figure 2 As shown in the figure, the cell where the UE is currently located is Cell0, and the corresponding frequency is f0. Cell1 is a neighboring 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 to MBS3 in the current communication system. 10 , Cell0 supports MBS1~MBS5, Cell1 supports MBS3~MBS6, Cell2 supports MBS5~MBS8, Cell3 supports MBS6, MBS9 and MBS 10 In this case, the MBS service may include at least one of the following:

[0093] MBS services supported by the current cell, namely MBS1 to MBS5;

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

[0095] MBS services supported by the current frequency, namely MBS1 to 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 may include the MBS services supported by the current cell (MBS1-MBS5), and may also include MBS services supported by non-adjacent cells with the same frequency (MBS6-MBS8 supported by Cell2).

[0098] In one 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 neighboring cells of the current cell;

[0101] MBS services supported by neighboring cells of the current cell but not supported by the current cell.

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

[0103] For example, there are 10 MBS services MBS1 to MBS 10 , the current cell is Cell0, the frequency is f0, and it supports MBS1 to MBS5; the neighboring cell is Cell1, the frequency is f1, and it supports MBS3 to MBS6; 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~MBS 10 ;

[0105] Supported by neighboring cells, i.e., MBS3 to MBS6;

[0106] The neighboring cell supports what the current cell does not support, namely MBS6.

[0107] On this basis, the UE can clarify the service area of ​​the MBS service that is 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 be regarded as a service of interest to the UE or can be received. In this way, when determining whether to receive a certain MBS service, in which cell to receive the MBS service, which MBS service to receive, determining the frequency priority of the cell and / or determining the target cell for cell reselection, etc., there are sufficient basis and more comprehensive choices, thereby improving the reliability of the MBS service.

[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 by different frequencies but not supported by the current frequency.

[0112] Normally, the UE can only obtain information about MBS services supported by the current frequency, but cannot obtain information about MBS services not supported by the current frequency. In this embodiment, the MBS services may include MBS services not supported by the current frequency, and the MBS services not supported by the current frequency may be supported by different frequencies or may not be supported by different frequencies.

[0113] Herein, the different frequency may refer to a frequency different from the current frequency.

[0114] The heterodyne frequency may also be a heterodyne frequency determined by a network device or indicated by a system message.

[0115] The heterofrequency may include the frequency of a neighboring cell, etc.

[0116] For example, there are 10 MBS services MBS1 to MBS 10 , the current cell is Cell0, the frequency is f0, and it supports MBS1 to MBS5; the neighboring cell is Cell1, the frequency is f1, and it supports MBS3 to MBS6; the inter-frequency cell is Cell2, the frequency is f2, and it supports MBS5 to MBS8; f0≠f1, f0≠f2, then the MBS service indicated by the indication information may 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 to MBS 10 ;

[0118] MBS services supported by different frequencies, namely MBS3 to MBS8;

[0119] MBS services that are supported by different frequencies but not supported by the current frequency, namely MBS6 to MBS8.

[0120] On this basis, the UE can clarify the service area of ​​the MBS service that is not supported by the current frequency according to the indication information. Even the MBS service that is not supported by the current frequency can be regarded as a service of interest to the UE or can be received. In this way, when determining whether to receive a certain MBS service, in which cell to receive the MBS service, which MBS service to receive, determining the frequency priority of the cell and / or determining the target cell for cell reselection, etc., there are sufficient basis and more comprehensive choices, thereby improving the reliability of the MBS service.

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

[0122] Specifically, the indication information may include multiple pieces of information. Accordingly, all the information in the indication information may be carried by the multicast control channel, and part of the information in the indication information may be carried by the multicast control channel.

[0123] As an example, the indication information may include business information, wherein:

[0124] Service information can be carried by the multicast control channel.

[0125] As an example, the indication information may include service area information, wherein:

[0126] The service area information may be carried by the multicast control channel.

[0127] Furthermore, as an example, the business area information may include business area and / or regional geographic location information, wherein:

[0128] The service area can be carried by the multicast control channel;

[0129] The regional geographic location information may be carried by a multicast control channel; or

[0130] Both the service area and the regional geographic location information may be carried by the multicast control channel; or

[0131] Other situations are not listed here one by one.

[0132] As an example, the indication information may include service information and service area information, wherein:

[0133] Both the service information and the service area information may be carried by the multicast control channel; or

[0134] The service information may be carried by the multicast control channel, and the service area information may be carried by other information, such as a system message; or

The heterofrequencies may be all heterofrequencies in the system that are different from the current frequency, or heterofrequencies determined or indicated by the base station, or frequencies of neighboring cells, and the like.

[0149] Specifically, the indication information may be composed of multiple pieces of information. Accordingly, all the information in the indication information may be carried by the system message, and part of the information in the indication information may be carried by the system message.

[0164] Other situations are not listed here one by one.

[0165] In one embodiment, multiple information in the indication information may be carried by different information at the same time.

[0166] Specifically, when multiple information is included in the indication information, each information may be carried by only one type of information, or may be carried by different types of information at the same time.

[0167] Exemplarily, when the indication information includes the service identifier, the area identifier and the area geographic location information at the same time:

[0168] In the first case, the service identifier and the area identifier are carried by the multicast control channel, and the regional geographic location information can be included in other information, such as system messages;

[0169] In the second case, the service identifier and the area identifier are carried by the multicast control channel, and the area identifier and the area geographic location information can be included in other information, such as system messages;

[0170] In the third case, the service identifier, the area identifier and the area geographic location information may all include other information, such as each system message block in the system message, and the service identifier is also included in the MBS configuration information;

[0172] There are other situations, which are not listed here one by one.

[0173] For example, the current communication system includes two areas: Area 1 and Area 2, and two different MBS services: MBS1 and MBS2. The service areas corresponding to MBS1 are Area 1 and Area 2, and the service area corresponding to MBS2 is Area 1.

[0174] Based on the first case above, the MBS configuration information includes, for MBS1, the MBS1 service identifier and its corresponding area identifiers of Area1 and Area2; for MBS2, the MBS2 service identifier and its corresponding area identifier of Area1; the system message includes the geographical location information of Area1 and the geographical location information of Area2;

[0178] There are other situations, which are not listed here one by one.

[0179] In one embodiment, the regional geographic location information is carried by a system message.

[0180] Specifically, the UE can clarify, according to the indication information, which MBS service area the UE is currently located at or will be located at, so as to correctly receive the corresponding MBS service through the service area, thereby improving the reliability of the MBS service.

[0181] In an exemplary application scenario, the UE can clarify its current or upcoming geographical location through various means such as self-positioning or information transmission, and then determine, based on the indication information, which service area's geographical location information corresponds to the current or upcoming geographical location. Thus, the UE can determine its service area, and thus, based on the indication information, can clarify the MBS services that can be received by the service area, thereby achieving reception of the MBS services.

[0182] In one embodiment, all or part of the indication information may also be carried by dedicated signaling.

[0183] Specifically, all or part of the indication information may be included in other information carried by dedicated signaling. For example, all or part of the indication information may be included in MBS configuration information carried by dedicated signaling, or may be included in other information carried by dedicated signaling.

[0184] In one embodiment, the MBS service includes: a multicast service and / or a broadcast service that can be received by a terminal in an RRC connected state and / or an RRC inactive state and / or an RRC idle state.

[0185] As an example, for a multicast service that can be received by a UE in an RRC connected state (RRC_CONNECTED), the UE may, based on the indication information, receive the multicast service based on the multicast configuration information (or based on the multicast service configuration information corresponding to the multicast service) in the service area corresponding to the multicast service (or in the service area corresponding to the multicast service configuration information corresponding to the multicast service) when in the RRC_CONNECTED state.

[0186] As an example, for a multicast service that can be received by a UE in an RRC inactive state (RRC_INACTIVE), the UE may, based on the indication information, receive the multicast service based on the multicast configuration information (or based on the multicast service configuration information corresponding to the multicast service) in the service area corresponding to the multicast service (or in the service area corresponding to the multicast service configuration information corresponding to the multicast service) when in the RRC_INACTIVE state.

[0187] As an example, for a broadcast service that can be received by a UE in the RRC_CONNECTED, RRC_INACTIVE or RRC_IDLE state, the UE may, based on the indication information, receive the broadcast service in the service area corresponding to the broadcast service (or in the service area corresponding to the MBS service configuration information corresponding to the broadcast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the broadcast service) when in the RRC_CONNECTED, RRC_INACTIVE or RRC_IDLE state.

[0188] In one embodiment, the service area is an area supporting MBS services.

[0189] Among them, supporting MBS services can be understood as supporting receiving MBS services, and can also be understood as supporting sending MBS services.

[0190] In this embodiment, Figure 3As shown, the area supporting reception of a certain MBS service is the circular area Area1 shown in the shaded area, and the service area of ​​the MBS service may refer to Area1.

[0191] In one embodiment, the service area is a cell that intersects with an area supporting the MBS service.

[0192] Among them, supporting MBS services can be understood as supporting receiving MBS services, and can also be understood as supporting sending MBS services.

[0193] In this embodiment, Figure 3 As shown, the area supporting reception of a certain MBS service is the circular area Area1 shown by the shaded area, and Cell1, Cell2, and Cell3 all have intersections with Area1, so the service area of ​​the MBS service may refer to Cell1, Cell2, and Cell3.

[0194] In one embodiment, the service area of ​​the MBS service includes one of the following:

[0195] The entire area of ​​an NTN cell;

[0196] Part of an NTN cell;

[0197] The entire area of ​​multiple NTN cells;

[0198] a portion of each of the plurality of NTN cells;

[0199] The entire area of ​​at least one NTN cell and a partial area of ​​at least one NTN cell.

[0200] In this embodiment, the service area of ​​the MBS service can be flexibly set according to actual conditions. Figure 4 As shown, the service area of ​​the MBS service may be the entire area of ​​an NTN cell (as shown in the shaded area of ​​case 1); may be a partial area of ​​an NTN cell (as shown in the shaded area of ​​case 2); may be the entire area of ​​multiple NTN cells (as shown in the shaded area of ​​case 3); may be a partial area of ​​each of the multiple NTN cells (as shown in the shaded area of ​​case 4); may be the entire area of ​​at least one NTN cell and a partial area of ​​at least one NTN cell (as shown in the shaded area of ​​case 5). Figure 4 The shaded area of ​​case 5 in FIG.

[0201] In one embodiment, the indication information is used for cell reselection and / or for determining the frequency priority of a cell.

[0202] In this embodiment, the service area of ​​the MBS service can be determined according to the indication information, and the cell reselection can be performed accordingly. For example, a cell including the service area (which may include all or part of the service area) is used as the target cell, or a cell covered by the service area (which may cover all or part of the cell) is used as the target cell. Figure 4 The cell containing the shaded area in any case can be used as the target cell. On this basis, according to the indication information, the service area of ​​the MBS service can be clarified, so that the target cell can be entered through the cell reselection process to receive the MBS service.

[0203] The frequency priority of the cell can also be determined according to the indication information. For example, the frequency priority of the cell containing the service area (which may be the whole or part of the service area) is higher, and the frequency priority of the cell not containing the service area is lower; or the frequency priority of the cell covered by the service area (which may be the whole or part of the covered cell) is higher, and the frequency priority of the uncovered cell is lower; for example, the larger the area or proportion of the service area in a cell, the higher the frequency priority of the cell can be; for example, the closer the distance between the service area in a cell and the current position of the UE or the current cell, the higher the frequency priority of the cell. This embodiment does not limit the specific method of determining the frequency priority of the cell. According to the indication information, the service area of ​​the MBS service can be clarified, so as to judge whether the UE has a greater probability, a longer duration and / or a faster speed in the service area after entering the cell, and accordingly the frequency priority of the cell can be reasonably determined to improve the reliability of the MBS service.

Specifically, the service area indication method can be executed by a service area indication device, and the service area indication device can be implemented by software and / or hardware and integrated in the user equipment.

Thus, in the NTN communication scenario, the UE can clearly know the service area of ​​the MBS service.

[0208] In the service area indication method of this embodiment, the user equipment specifies the service area of ​​the MBS service according to the received indication information, which can provide a basis for determining whether to receive the MBS service, in which cell to receive the MBS service, determining the frequency priority of the cell or how to determine the target cell for cell reselection, thereby improving the reliability of the MBS service.
