Description

Information sending and receiving method and device Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] In traditional terrestrial networks (TN) systems, broadcast or multicast services are typically available to all registered and service-capable user equipment (UE) within the cell providing the service. NR non-terrestrial networks (NTN) also support broadcast or multicast services. NTN systems have a wider coverage area than TN systems, and leveraging this feature, broadcast or multicast services can provide significant added value for NR NTN systems.

[0003] Depending on the satellite's altitude, the ground coverage of NR NTN cells can be as large as to encompass two or more countries. Figure 1 is a schematic diagram of NR NTN system cell coverage. As shown in Figure 1, the NR NTN system covers two countries, Country A and Country B.

[0004] Due to legal regulations, billing, and information content, certain services, such as broadcast or multicast services, may have limited terrestrial service coverage. For example, the service may only be available in certain countries or regions covered by NTN cells, or some countries or regions may prohibit the service from being provided to devices in their own country or region. In other words, the service's intended service area (ISA) encompasses only a portion of the NTN cell coverage area.

[0005] In the work of 3GPP Release 19, SIB will be enhanced to indicate the expected service area of ​​the service.

[0006] It should be noted that the above description of the technical background is merely for the purpose of providing a clear and complete description of the technical solutions of this application and facilitating understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0007] Summary of the Invention

[0008] According to the current 3GPP NR NTN WID (Work Item Description), SIB will be used to indicate the intended service area (ISA). However, how to perform subsequent processing based on the indication of the intended service area is currently unclear.

[0009] The inventors have discovered that depending on the reasons why the service area of ​​a service is limited (ie, the expected service area of ​​the service only includes a portion of the cell coverage), after determining that the service area of ​​the service is limited, the subsequent processing also needs to be adjusted accordingly.

[0010] For example, in the case where the service area of ​​a service is limited because the content is only applicable to certain countries and regions (such as weather forecasts, promotions, local news, etc.), it may not be necessary or desirable for terminal devices outside the expected service area to further parse the service, thereby avoiding the overhead caused by monitoring, detection and decoding processes; and due to laws and regulations, etc., there are cases where the service area of ​​the service is limited because the service is banned in certain countries or regions. Terminal devices outside the expected service area are prohibited from parsing the service.

[0011] In addition, for services that are not applicable but not prohibited outside the expected service area, after indicating the expected service area of ​​the service in the signaling, the terminal device can decide whether to continue to process the service based on its capabilities, needs, etc.

[0012] For example, for terminal devices that support services within the coverage area of ​​part of the cell and are interested in the service, it can determine whether it is within the expected service area of ​​the service based on the expected service area indicated by the network and the area where the terminal device is located: if so, it can further read and monitor, detect and analyze the service; if not, it can stop any related processing of the service to avoid unnecessary overhead, or it can continue to monitor the service and other behaviors as needed.

[0013] For terminal devices that do not support services that serve part of the cell coverage area, for example, terminal devices that do not support reading indications of expected service areas, they will still continue to receive the services outside the expected service area.

[0014] However, for services prohibited outside the intended service area, terminal devices outside the intended service area are not allowed to access the content of the service. In order to comply with legal and regulatory requirements, the network even hopes that the service will not be visible to terminal devices outside the intended service area. However, simply indicating the intended service area of ​​a service may not guarantee that the service will not be monitored, detected, or analyzed by terminal devices outside the intended service area, such as malicious monitoring or terminal devices being unable to determine whether the service is allowed to be received in the current location.

[0015] In order to solve one or more of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving information.

[0016] According to a first aspect of an embodiment of the present application, an information transceiver is provided, which is arranged in a terminal device, and the device includes: a first receiving unit, which receives first information from a network device, wherein the first information is at least used to indicate information related to a service area of ​​a business, and the business is a business with a specified service area; and a first processing unit, which determines how to process the business based on the first information; or, a first sending unit, which sends second information to the network device, wherein the second information is at least used by the network device to determine whether the terminal device is located in the service area of ​​the business.

[0017] According to a second aspect of an embodiment of the present application, an information sending and receiving device is provided, which is arranged in a network device, and the device includes: a second sending unit, which sends first information to a terminal device, and the first information is at least used to indicate information related to a service area of ​​a service, and the service is a service with a specified service area; and / or, a second receiving unit, which receives second information from the terminal device, and the second information is at least used by the network device to determine whether the terminal device is located in the service area of ​​the service.

[0018] According to the third aspect of the embodiment of the present application, a communication system is provided, which includes a terminal device and / or a network device, the terminal device includes the apparatus according to the first aspect of the embodiment of the present application, and the network device includes the apparatus according to the second aspect of the embodiment of the present application.

[0019] According to a fourth aspect of an embodiment of the present application, a method for sending and receiving information is provided, the method comprising: a terminal device receiving first information from a network device, the first information being at least used to indicate information related to a service area of ​​a service, the service being a service with a specified service area; and the terminal device determining how to handle the service based on the first information; or, the terminal device sending second information to the network device, the second information being at least used by the network device to determine whether the terminal device is located within the service area of ​​the service.

[0020] According to a fifth aspect of an embodiment of the present application, a method for sending and receiving information is provided, the method comprising: a network device sending first information to a terminal device, the first information being used at least to indicate information related to a service area of ​​a service, the service being a service with a specified service area; and / or the network device receiving second information from the terminal device, the second information being used at least for the network device to determine whether the terminal device is located within the service area of ​​the service.

[0021] According to the sixth aspect of the embodiment of the present application, a computer-readable program is provided, wherein when the program is executed in an information transceiving apparatus or a terminal device, the program enables the information transceiving apparatus or the terminal device to execute the information transceiving method described in the fourth aspect of the embodiment of the present application.

[0022] According to the seventh aspect of the embodiment of the present application, a computer-readable program is provided, wherein when the program is executed in an information transceiver device or a network device, the program enables the information transceiver device or the network device to execute the information transceiver method described in the fifth aspect of the embodiment of the present application.

[0023] According to the eighth aspect of the embodiment of the present application, a storage medium storing a computer-readable program is provided, wherein the computer-readable program enables an information sending and receiving apparatus or a terminal device to execute the information sending and receiving method described in the fourth aspect of the embodiment of the present application.

[0024] According to the ninth aspect of the embodiment of the present application, a storage medium storing a computer-readable program is provided, wherein the computer-readable program enables an information sending and receiving apparatus or a network device to execute the information sending and receiving method described in the fifth aspect of the embodiment of the present application.

[0025] One of the beneficial effects of the embodiments of the present application is that it can adjust the handling method of the service based on the restricted attributes of the service with restricted service area. For example, for services that are not applicable outside the expected service area, the terminal device decides whether it is within the expected service area and how to handle it. For example, when the terminal device approaches the expected service area, it monitors the service in advance, etc., which increases flexibility. For services that are prohibited from being used outside the expected service area, the network determines whether the terminal device is within the expected service area and assigns a specific identifier to the terminal device accordingly, thereby supplementing stricter restrictions according to the degree of restriction of the service, and by using a specific identifier to scramble the channel, it prevents terminal devices outside the expected service area from using related services.

[0060] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0061] Embodiments of the first aspect

[0062] An embodiment of the present application provides a method for sending and receiving information, which is applied to a terminal device, such as the terminal device 102 in Figure 2.

[0063] FIG3 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0064] 301: The terminal device receives first information from the network device, where the first information is used to indicate at least information related to a service area of ​​a service, where the service is a service with a designated service area; and

[0065] 302: The terminal device determines how to process the service according to the first information; or

[0066] 303: The terminal device sends second information to the network device, where the second information is at least used by the network device to determine whether the terminal device is located in the service area of ​​the service.

[0067] Operation 302 and operation 303 are alternative relationships, that is, the method includes operation 301 and operation 302, or the method includes operation 301 and operation 303.

[0068] In operation 301, a terminal device receives first information from a network device; the first information is used to indicate at least information related to a service area of ​​a service, where the service has a designated service area.

[0069] Alternatively, operation 301 may also be described as: the terminal device receives service area related information of a service from the network device, where the service is a service with a designated service area.

[0070] In some embodiments, the service is a broadcast or multicast service;

[0071] In some embodiments, a service with a designated service area means that a broadcast or multicast service may be a customized service within a specific range (service area) and is only allowed or valid within that specific range. In a cell with a very large coverage area, the service may only be applicable to a portion of the cell rather than the entire cell coverage area. Therefore, the network needs to notify the terminal device of information related to the service area of ​​the service.

[0072] In some embodiments, the service area of ​​a service refers to a designated service area of ​​the service, which may also be referred to as an expected service area of ​​the service, a predetermined service area of ​​the service, or an intended service area of ​​the service.

[0073] In some embodiments, the area not served by the service refers to the area outside the designated service area of ​​the service, which can also be called the non-service area of ​​the service, the non-expected service area of ​​the service, the non-scheduled service area of ​​the service, or the area not expected to be served by the service.

[0074] In some embodiments, the broadcast or multicast service is not limited to MBS (Multicast and Broadcast Services) whose expected service area does not include the entire cell coverage area, but may also be a broadcast service or multicast service that other networks expect to provide to terminal users in a predetermined area.

[0075] In some embodiments, the first information includes: an indication that the service is a service with a designated service area and / or information about the service area of ​​the service.

[0076] For example, the service area related information indicated by the first information may include the expected service area of ​​the service, that is, the designated service area information in which the network allows or expects the terminal device to use the service, and may also include the non-expected service area of ​​the service, that is, the area information in which the network prohibits or does not expect the terminal device to use the service, that is, the first information includes the service area information of the service;

[0077] For another example, the service area related information indicated by the first information may also include or only include indication information for indicating that the service is a service with a specific area rather than the entire cell as its service range, that is, the first information includes an indication that the service is a service with a specified service area, that is, the service is not a cell-specific service.

[0078] In some embodiments, the indication that the service is a service with a designated service area includes: introducing a new parameter or enhancing the definition of an existing parameter in the SIB or configuration information related to the service, that is, explicitly indicating that the service is a service with a designated service area (restricted service area);

[0079] For example, the service being a service with a designated service area is indicated by at least one of the following parameters:

[0080] intendedArea / intendedCountry / intendedPLMN / intendedTAI ENUMERATED{true};

[0081] areaScope / cuntryScope / PLMNSope / TAIScope / partialScope ENUMERATED{true};

[0082] The parameter areaScope of the extended SIB type information, for example, areaScope-19, is used to indicate that the SIB and the services associated with the SIB are services with a specified service area (limited service area).

[0083] In some embodiments, the indication that the service is a service with a specified service area includes: indicating that the terminal device reports location-related information in the SIB or configuration information related to the service, that is, implicitly indicating that the service is a service with a specified service area (restricted service area).

[0084] In some embodiments, the information of the service area (expected service area) of the service includes at least one of the following:

[0085] A specific beam identifier or a list of beam identifiers;

[0086] A specific PLMN ID or a list of PLMN IDs;

[0087] A specific country code (MCC) or a list of country codes;

[0088] A specific network code (MNC) or a list of network codes;

[0089] A specific Tracking Area Identity (TAI) or a list of Tracking Area Identity;

[0090] A specific area ID (Area ID) or a list of area IDs, which are assigned by the network to the planned ground area.

[0091] In some embodiments, services having a designated service area include services that are not applicable outside of the intended service area.

[0092] For example, for some services with a specific range, their service area is limited. For example, under the NTN system, the MBS service provided to certain specific countries or regions is only applicable to a specific range or only valid within that specific range. The expected service range of the service may only include part of the cell coverage. In the same cell, terminal devices within the expected service area can obtain the services provided by the service by reading relevant signaling configurations, etc.; while terminal devices outside the expected service area may not want to parse or receive the service to avoid unnecessary detection, processing, storage and other related expenses. The above-mentioned services are services that are not applicable outside the expected service area (rather than services that are prohibited from being used outside the expected service area).

[0093] In some embodiments, for a service that is not applicable outside the expected service area (rather than a service that is prohibited from being used outside the expected service area), operation 302 may be performed, that is, the terminal device determines how to handle the service based on the first information. This implementation is referred to as the "first implementation."

[0094] Accordingly, in the first embodiment, operation 302 includes: the terminal device determines whether the terminal device is located within the service area (expected service area) of the service based on the information of the service area (expected service area) and the relevant information of the current location of the terminal device; the terminal device determines the processing of the service based on whether the terminal device is located within the service area (expected service area) of the service.

[0095] FIG4 is a schematic diagram of a first embodiment of the information sending and receiving method of the embodiment of the present application. As shown in FIG4, the method includes:

[0096] 401: The terminal device receives information about the service area (expected service area) of the service from the network device;

[0097] 402: The terminal device determines whether the terminal device is located within the service area (expected service area) of the service based on the service area (expected service area) of the service and the relevant information of the current location of the terminal device; and

[0098] 403: The terminal device determines how to process the service according to whether the terminal device is located in the service area (expected service area) of the service.

[0099] FIG5 is an interaction diagram of a first embodiment of the information sending and receiving method of an embodiment of the present application. As shown in FIG5 , the method includes:

[0100] 501: The network device sends information about the service area (expected service area) of the service to the terminal device;

[0101] 502: The terminal device determines whether the terminal device is located within the service area (expected service area) of the service based on the service area (expected service area) of the service and the relevant information of the current location of the terminal device.

[0102] 503: The terminal device determines how to process the service according to whether the terminal device is located in the service area (expected service area) of the service.

[0103] In operations 402 and 502 , the terminal device determines whether the terminal device is located in the service area (expected service area) of the service based on the service area (expected service area) information and relevant information of the current location of the terminal device.

[0104] For example, the relevant information about the current location of the terminal device includes at least one of the following:

[0105] Beam ID;

[0106] PLMN ID;

[0107] Country code MCC;

[0108] Network code MNC;

[0109] Tracking Area Identity (TAI);

[0110] Area ID assigned by the network;

[0111] User Location Information (ULI);

[0112] RAN Area ID;

[0113] zone ID;

[0114] The terminal device location based on GNSS, wireless network, WLAN, Bluetooth, sensor or TBS positioning.

[0115] In operations 403 and 503, the terminal device determines how to process the service based on whether the terminal device is located in the service area (expected service area) of the service. For example, the specific implementation of operation 403 includes at least one of the following:

[0116] When the terminal device is within the service area (expected service area), the terminal device reads the relevant configuration of the service and obtains the content of the service;

[0117] When the terminal device is outside the service area (expected service area), the terminal device stops or reduces at least one of monitoring, detecting, parsing and obtaining information related to the service;

[0118] When the terminal device is outside the service area (expected service area) and satisfies the first condition, the terminal device initiates or adds at least one of monitoring, detecting, parsing, and obtaining information related to the service;

[0119] For example, the service-related information includes at least one of the following: system information related to the service; scheduling information related to the service; configuration information related to the service; specific content of the service;

[0120] For example, the first condition includes at least one of the following: the distance between the terminal device and the boundary of the service area (expected service area) is less than a first threshold; the terminal device is moving toward the boundary of the service area (expected service area).

[0121] That is, for example:

[0122] When the terminal device is within the expected service area, read the relevant configuration of the service and further obtain the content of the service; and / or,

[0123] If the terminal device is outside the expected service area, stop monitoring, detecting, parsing, obtaining, etc. of system information / scheduling configuration / specific content related to the service; and / or,

[0124] When a terminal device is outside the expected service area but the distance from the boundary of the expected service area is less than a specified threshold, start or increase monitoring, detection, analysis, acquisition, etc. of system information, scheduling configuration, specific content, etc. related to the service; and / or,

[0125] When a terminal device is outside the expected service area but is moving toward the boundary of the expected service area, start or increase monitoring, detection, analysis, acquisition, etc. of system information, scheduling configuration, specific content, etc. related to the service; and / or,

[0126] For the situation where the terminal device is outside the expected service area but the distance to the boundary of the expected service area is less than the specified threshold and is moving towards the boundary of the expected service area, start or increase the monitoring, detection, parsing, acquisition, etc. of system information, scheduling configuration, specific content, etc. related to the service.

[0127] In some embodiments, for services that are not applicable outside the expected service area (rather than services that are prohibited from being used outside the expected service area), operation 303 may also be performed, that is, the terminal device sends second information to the network device, and the second information is at least used by the network device to determine whether the terminal device is located in the service area (expected service area) of the service. That is, the network device determines whether the terminal device is located in the service area (expected service area) of the service based on the second information. This embodiment is referred to as the "second embodiment."

[0128] For example, the second information includes relevant information about the current location of the terminal device sent by the terminal device to the network device.

[0129] For example, the second information may also include a location reporting request indication sent by the terminal device to the network device, requesting the network device to allocate resources for the terminal device to report relevant information about the current location, so that the terminal device can send relevant information about the current location on the allocated resources.

[0130] In addition, the specific content of the relevant information of the current location of the terminal device is similar to that of the first embodiment described above and will not be repeated here.

[0131] In a second embodiment, the method further includes: the terminal device receiving third information from the network device, the third information being at least used to indicate whether the terminal device is located in a service area (expected service area) of the service;

[0132] For example, the third information includes at least one of the following:

[0133] A dedicated identifier; for example, a group ID or area ID related to the intended service area;

[0134] A bit indicating whether the terminal device is within the service area (expected service area); for example, a bit indicating whether the terminal device is within the expected service area by True or False;

[0135] A bit indicating that the terminal device is within the service area (expected service area); for example, True indicates that the terminal device is within the expected service area.

[0136] In some embodiments, after receiving the second information reported by the terminal device, the network device determines whether the terminal device is located in the expected service area, and indicates to the terminal device whether the terminal device is located in the expected service area of ​​the service; however, for example, in the case where the network device stores the valid current location information of the terminal device, it can directly indicate to the terminal device whether the terminal device is located in the expected service area of ​​the service without instructing or waiting for the terminal device to report the second information.

[0137] In addition, the network device does not receive the second information reported by the terminal device within the specified time, and the network device does not store the valid current location information of the terminal device. The network device determines that the terminal device is located outside the expected service area.

[0138] In addition, the network device may send an indication of whether the terminal device is located in the expected service area of ​​the service to the terminal device, or may send an indication of whether the terminal device is located in the expected service area only to the terminal device located in the expected service area.

[0139] In a second embodiment, the method further includes: the terminal device determining, based on whether the terminal device indicated in the third information is located within the service area (expected service area) of the service, how to process the service. For specific implementation, reference may be made to the specific implementation of operations 403 and 503 above, which will not be repeated here.

[0140] FIG6 is a schematic diagram of a second embodiment of the information sending and receiving method of the embodiment of the present application. As shown in FIG6, the method includes:

[0141] 601: The terminal device receives an indication from the network device that the service is a service with a designated service area;

[0142] 602: The terminal device sends information related to the current location of the terminal device to the network device;

[0143] 603: The terminal device receives an indication from the network device indicating whether the terminal device is located within the service area (expected service area) of the service.

[0144] 604: The terminal device determines how to process the service according to the indication of whether the terminal device is located in the service area (expected service area) of the service.

[0145] FIG7 is an interaction diagram of a second embodiment of the information sending and receiving method of an embodiment of the present application. As shown in FIG7 , the method includes:

[0146] 701: The network device sends an indication to the terminal device that the service is a service with a designated service area;

[0147] 702: The terminal device sends information related to the current location of the terminal device to the network device;

[0148] 703: The network device determines whether the terminal device is located in the service area (expected service area) of the service based on the relevant information of the current location of the terminal device.

[0149] 704: The network device indicates to the terminal device whether the terminal device is located in the service area (expected service area) of the service;

[0150] 705: The terminal device determines how to process the service according to the indication of whether the terminal device is located in the service area (expected service area) of the service.

[0151] In some embodiments, if the network device stores valid current location information of the terminal device, operations 602 and 702 may be omitted and operations 603 and 703 may be performed directly.

[0152] As mentioned above, for services that are not applicable outside the expected service area (rather than services that are prohibited from use outside the expected service area), whether the terminal device monitors, detects, and analyzes the service is determined by the terminal device. For terminal devices outside the expected service area, how to handle related services can be flexibly determined based on different scenarios.

[0153] For example, in the first implementation, whether a terminal is located in the expected service area is determined by the terminal device. Based on the expected service area indicated by the network and its own location, the terminal device can directly determine whether it is within the expected service area of ​​the service. This requires less signaling interaction, but requires the terminal device to ensure accurate mapping between the current location and the area information.

[0154] For example, for the second embodiment, whether the terminal device is located within the expected service area is determined by the network device. The network device determines whether the terminal device is within the expected service area of ​​the service based on the relevant information of the terminal device's current location. The relevant information of the terminal device's current location is the latest and valid relevant information of the terminal device's current location that is available in the network. The relevant information of the terminal device's current location can be the relevant information of the current location contained in the second information reported by the terminal device, or the relevant information of the terminal device's current location that is already stored in the network device and is still valid. Thus, the signaling content is simpler and fewer requirements are placed on the terminal device.

[0155] In some embodiments, services having designated service areas also include services that are prohibited from being used outside of the intended service area.

[0156] For example, for certain services with specific scopes, their service areas are restricted. For example, under the NTN system, MBS services provided to certain specific countries or regions are only allowed to be provided within a specific scope, or in other words, outside of this specific scope, the service is prohibited. Providing or using this service may violate local policies or laws and regulations, or cause adverse consequences. When the expected service area of ​​the service may only include part of the cell coverage area, it is necessary to ensure that terminal devices within the expected service area in the same cell can use the services provided by the service; while for terminal devices outside the expected service area, the terminal devices may not be allowed to receive the content of the service, and may even be prohibited from monitoring, detecting, and other behaviors related to the service.

[0157] In some embodiments, for a service that is prohibited from being used outside the expected service area, operations 301 and 303 are performed. That is, the network device sends first information to the terminal device, and the terminal device sends second information to the network device based on the first information. The second information is at least used by the network device to determine whether the terminal device is located within the service area (expected service area) of the service. That is, the network device determines whether the terminal device is located within the service area (expected service area) of the service based on the second information. This embodiment is referred to as the "third embodiment."

[0158] In a third embodiment, the first information includes an indication that the service is a service with a designated service area. For example, the network device sends the indication via an SIB message or an RRC message.

[0159] Similar to the above embodiment, the indication that the service is a service with a designated service area includes: introducing a new parameter in the SIB or configuration information related to the service or enhancing the definition of an existing parameter, that is, explicitly indicating that the service is a service with a designated service area (restricted service area);

[0160] For example, the service being a service with a designated service area is indicated by at least one of the following parameters:

[0161] intendedArea / intendedCountry / intendedPLMN / intendedTAI ENUMERATED{true};

[0162] areaScope / cuntryScope / PLMNSope / TAIScope / partialScope ENUMERATED{true};

[0163] The parameter areaScope of the extended SIB type information, for example, areaScope-19, is used to indicate that the SIB and the services associated with the SIB are services with a specified service area (limited service area).

[0164] In some embodiments, the indication that the service is a service with a specified service area includes: indicating that the terminal device reports location-related information in the SIB or configuration information related to the service, that is, implicitly indicating that the service is a service with a specified service area (restricted service area).

[0165] In some embodiments, the method further includes: the terminal device receiving a location information report request from the network device. For example, if the network device is currently providing or preparing to provide the service, the location information report request is further transmitted to the terminal device via broadcast or terminal device-specific means. Furthermore, if the network device already has the location information of the terminal device stored and the information is still valid, that is, if the network device has stored valid current location information of the terminal device, the network device may not transmit the location information report request to the terminal device.

[0166] For example, the report type includes at least one of the following:

[0167] Non-periodic reporting, such as instructing the terminal device to report immediately;

[0168] Semi-persistent reporting, for example, the reporting interval is configured according to the relative speed between the terminal device and the satellite, and the reporting interval can be at the ms / s / min / hour level;

[0169] Periodic reporting, for example, a reporting interval that is the same as or similar to a reporting interval of semi-persistent reporting.

[0170] For example, the relevant information about the current location of the terminal device includes at least one of the following:

[0171] Beam ID;

[0172] PLMN ID;

[0173] Country code MCC;

[0174] Network code MNC;

[0175] Tracking Area Identity (TAI);

[0176] Area ID assigned by the network;

[0177] User Location Information (ULI);

[0178] RAN Area ID;

[0179] zone ID;

[0180] The terminal device location based on GNSS, wireless network, WLAN, Bluetooth, sensor or TBS positioning.

[0181] For example, the broadcasting method includes at least one of the following:

[0182] Broadcast in the entire cell, which includes the service area (expected service area) of the service and the non-service area (non-expected service area) of the service;

[0183] Broadcast in the entire cell that the cell is providing or is about to provide the service;

[0184] It is only broadcast on a specific beam, and only part of the coverage area of ​​the beam belongs to the service area (expected service area) of the service.

[0185] For example, a location information report request is sent in a dedicated manner to at least one of the following terminal devices:

[0186] All terminal devices in the community;

[0187] The coverage area mapped by the reported location information only partially belongs to the service area (expected service area) of the terminal device;

[0188] A specific beam is reported, and only part of the coverage area of ​​the beam belongs to the terminal equipment in the service area (expected service area) of the service;

[0189] Terminal devices that report multiple locations of the same type, such as multiple PLMN IDs;

[0190] Terminal equipment whose reported location is near the boundary of the service area (expected service area) of the service;

[0191] Terminal devices whose newly reported locations are closer to the boundary of the service area (expected service area) of the service than the previously reported locations;

[0192] A terminal device whose reported location is near the boundary of the service area (expected service area) of the service and whose newly reported location is closer to the boundary than the previously reported location.

[0193] In operation 303, the terminal device sends second information to the network device, and the second information is at least used by the network device to determine whether the terminal device is located in the service area (expected service area) of the service. For example, the terminal device sends relevant information about the current location of the terminal device to the network device based on the location information report request received from the network device.

[0194] In some embodiments, the terminal device sends the second information (e.g., information related to the current location of the terminal device) to the network device in at least one of the following ways:

[0195] Sending the second information to the network device in a conventional manner; for example, reporting information such as TAI, PLMN, Beam ID, and ULI;

[0196] Periodically sending the second information according to the configuration of the network device;

[0197] When the terminal device is interested in the service, the second information is sent to the network device; for example, including at least one of the following:

[0198] The terminal device requests the network to report a location related to the service, and reports the second information according to the resources allocated by the network;

[0199] The terminal device reports the second information on resources pre-allocated by the network;

[0200] Including the second information in the service-related signaling message. For example, for the MBS service, the second information is included in the MBSInterestIndication-r17 message, notifying the network that the terminal device is interested in the MBS service and reporting the second information to the network.

[0201] reporting second information when receiving a location information report request from the network;

[0202] When it is detected that a certain service area only (maybe) includes a partial cell coverage area, the second information is reported.

[0203] In some embodiments, the network device determines whether the terminal device is located within the expected service area of ​​the service based on the relevant information about the terminal device's current location. The relevant information about the terminal device's current location is the latest, valid, and available information about the terminal device's current location in the network. It can be the relevant information about the current location contained in the second information reported by the terminal device, or the relevant information about the current location of the terminal device that is already stored in the network device and is still valid. Furthermore, if the network device does not receive the second information reported by the terminal device within a specified time, and the network device does not store valid current location information about the terminal device, the network device determines that the terminal device is outside the expected service area.

[0204] In some embodiments, the method further includes: the terminal device that meets the second condition receives a first identifier from the network device, where the first identifier is at least used to scramble transmission related to the service on the physical channel, that is, the network device assigns a specific identifier (first identifier) ​​or a related identifier list to the terminal device that meets the second condition;

[0205] For example, the manner in which the network device allocates the first identifier includes at least one of the following:

[0206] Adding the first identifier to the terminal device that meets the second condition;

[0207] modifying the identifier assigned to the terminal device that meets the second condition so that the identifier assigned to the terminal device that meets the second condition includes the first identifier;

[0208] For example, the second condition includes at least one of the following:

[0209] within the service area (expected service area) of the business;

[0210] The user is within the service area of ​​the service and the distance from the boundary of the service area (expected service area) is less than a second threshold, but the user is not moving toward the boundary of the service area (expected service area);

[0211] The service area of ​​the service is within the service area and the distance from the boundary of the service area (expected service area) is greater than or equal to the second threshold.

[0212] In addition, for example, the specific content of the second condition is determined according to the strictness of the service restriction attribute.

[0213] In some embodiments, for MBS services, the first identifier includes at least one of a G-RNTI, a G-CS-RNTI, and a MCCH-RNTI. That is, the network device uses a specific G-RNTI, G-CS-RNTI, or MCCH-RNTI to scramble the physical channel for scheduling and transmitting MBS services.

[0214] In some embodiments, for a terminal device within a service area (expected service area) of the service, the method further includes: the terminal device further receiving fourth information from the network device, the fourth information including at least one of the following: scheduling information related to the service; configuration information related to the service; and specific content of the service. Furthermore, the fourth information is scrambled using the first identifier.

[0215] That is, the network device determines whether the terminal device is located within the service area of ​​the service based on the relevant information of the current location of the terminal device; and the network device uses the first identifier to scramble the physical channel of the transmission related to the service, wherein the relevant information of the current location of the terminal device is the relevant information of the current location of the terminal device that is available, latest and valid in the network.

[0216] FIG8 is a schematic diagram of a third embodiment of the information sending and receiving method according to an embodiment of the present application. As shown in FIG8 , the method includes:

[0217] 801: The terminal device receives an indication from the network device that the service is a service with a designated service area;

[0218] 802: The terminal device receives a location information report request from the network device;

[0219] 803: The terminal device sends information related to the current location to the network device;

[0220] 804: The terminal device located in the service area (expected service area) of the service receives the first identifier from the network device;

[0221] 805: The terminal device receives, from the network device, the transmission on the physical channel related to the service encrypted with the first identifier.

[0222] FIG9 is an interaction diagram of a third embodiment of the information sending and receiving method of an embodiment of the present application. As shown in FIG9 , the method includes:

[0223] 901: The network device sends an indication to the terminal device that the service is a service with a designated service area;

[0224] 902: The network device sends a location information report request to the terminal device when providing or preparing to provide the service;

[0225] 903: The terminal device sends information related to the current location to the network device;

[0226] 904: The network device determines whether the terminal device is located in the service area (expected service area) of the service based on the relevant information of the current location of the terminal device.

[0227] 905: The network device allocates a first identifier to a terminal device located in a service area (expected service area) of the service;

[0228] 906: The network device uses the first identifier to scramble transmission related to the service on the physical channel;

[0229] 907: The terminal device located in the service area (expected service area) of the service uses the first identifier to receive, from the network device, transmission on the physical channel related to the service that is scrambled using the first identifier.

[0230] In some embodiments, if the network device stores valid current location information of the terminal device, operations 802 - 803 and 902 - 903 may be omitted.

[0231] In some embodiments, as shown in FIG9 , the method further includes the following optional operations:

[0232] 908: The network device adjusts the configuration of the terminal device reporting location information based on the relevant information of the current location reported by the terminal device; for example, performing operation 903 based on the adjusted configuration;

[0233] For example, the adjusted configuration includes at least one of the following:

[0234] Type of report; type of location information required to be reported; method of notification; terminal device to be notified; reporting period; frequency of reporting.

[0235] For example, when the position reported by the terminal device is closer to the boundary of the service area (expected service area) than the previously reported position, the terminal device is instructed to increase the reporting frequency.

[0236] In some embodiments, as shown in FIG9 , the method further includes the following optional operations:

[0237] 909: The network device further adjusts the first identifier assigned to the terminal device according to the relevant information of the current location reported by the terminal device; for example, performing operation 905 according to the adjusted first identifier;

[0238] For example, the manner of adjusting the first identifier assigned to the terminal device includes at least one of the following:

[0239] Adding the first identifier;

[0240] Modify the identifier assigned to the terminal device to include the first identifier;

[0241] Releasing the first identifier that has been allocated to the terminal device;

[0242] The first identifier that has been assigned to the terminal device is deleted.

[0243] For example, for a terminal device that has been assigned a specific identifier for resolving a service, if the network device does not receive the expected report of information related to the current location of the terminal device or the reported current location of the terminal device is outside the expected service area of ​​the service, the network device will release the specific identifier of the terminal device.

[0244] Thus, in the third embodiment, whether the terminal device is located within the expected service area of ​​the service, and whether it can monitor, detect, and resolve services with restricted service areas, is determined by the network. For example, based on the location of the terminal device, a specific identifier is used to distinguish terminal devices inside and outside the expected service area of ​​the service, and the specific identifier is used to schedule related services, so that terminal devices outside the expected service area cannot resolve transmissions related to the service, that is, prohibited related services are not provided to these terminal devices. In addition, for example, based on the relevant information of the current location reported by the terminal device and stored in the network, the network can not only determine whether the terminal device is within the expected service area, but also determine the movement trend of the terminal device, and then adjust the configuration of the terminal device reporting the relevant information of the current location, such as increasing the reporting frequency to obtain changes in the terminal device location more timely, or reducing the reporting frequency to save reporting overhead, etc.

[0245] As can be seen from the above embodiments, the handling method of the service with restricted service area can be adjusted according to the restricted attributes of the service. For example, for services that are not applicable outside the expected service area, the terminal device decides how to handle them, such as monitoring the service in advance when the terminal device is outside the expected service area and close to the expected service area, which increases flexibility; for services that are prohibited outside the expected service area, the network determines whether the terminal device is within the expected service area and assigns a specific identifier to the terminal device within the expected service area according to the degree of restriction of the service, thereby adding stricter restrictions to the area where the service is provided; by using a specific identifier to scramble the channel, terminal devices outside the expected service area or about to move outside the expected service area are prevented from using related services.
