[0002] To achieve global wireless access coverage, the industry has proposed a non-terrestrial network (NTN) architecture, which is mainly implemented by using satellites as communication base stations, or by satellites relaying wireless communication signals of terrestrial base stations to provide wireless access services for a large area below the satellites.

[0003] In the current NTN architecture, satellites can provide different types of broadcast services.

[0058] To facilitate a clear description of the technical solutions of the embodiments of this application, the following briefly introduces some terms and technologies involved in the embodiments of this application:

[0059] In the embodiments of the present application, terms such as "first" and "second" are used to distinguish identical or similar items with basically the same functions and roles. For example, the first chip and the second chip are only used to distinguish different chips, and do not limit their sequence. Those skilled in the art can understand that terms such as "first" and "second" do not limit the quantity and execution order, and terms such as "first" and "second" do not necessarily limit them to be different.

[0060] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to give examples, illustrations or explanations.

[0061] In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. The character " / " generally represents that the associated objects before and after are in an "or" relationship. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, c can be single or multiple.

As Figure 1 shown, the communication system 100 may include at least one access network device (such as Figure 1 110a, 110b, 110c in Figure 1 ), and may also include at least one terminal (such as Figure 1 120a - 120g in

[0063] Figure 2 It is a schematic diagram of the architecture of a non-terrestrial network (NTN) provided by the embodiments of the present application. As Figure 2As shown in the figure, the satellite has some or all of the functions of an access network device and can be called a satellite base station, which can provide wireless access services and schedule radio resources for terminal devices accessing the network through this satellite base station. The satellite base station communicates with the UE through the user-universal terrestrial radio access network (Uu) interface. Among them, the satellite base station and the core network (CN) can communicate through the next generation (NG) interface. The satellite base station and the core network can interact with the non-access stratum (NAS) signaling of the core network and the service data of users through the NG interface. The satellite radio interface (SRI) is the feeder link between the NTN gateway and the satellite. In Figure 2 the satellite radio interface (Satellite Radio Interface, SRI) can be implemented as part of the NG interface to enable communication and interaction between the satellite and the core network. In the embodiments of this application, the access network device is taken as an example of a satellite base station for introduction.

[0064] The network device provided in the embodiments of this application can be a base station, Node B, evolved Node B (eNodeB or eNB), transmission reception point (TRP), next generation Node B (gNB) in the 5th generation (5G) mobile communication system, an access network device in the open radio access network (O-RAN or open RAN), a base station in a future mobile communication system, and the network device can be a satellite base station in non-terrestrial networks (NTN) (such as Figure 2 the satellite base station in), or a base station in a future mobile communication system, or an access node in a wireless fidelity (WiFi) system, etc. Alternatively, the network device can be a module or unit that completes some functions of the base station. For example, it can be a central unit (CU), a distributed unit (DU), a central unit control plane (CU control plane, CU-CP) module, or a central unit user plane (CU user plane, CU-UP) module, etc. The access network device can be a satellite base station (such asFigure 1 110a) in Figure 1 110b) in Figure 1 110c) in It can also be a relay node, a donor node, etc. In this application, the specific technologies and specific device forms adopted by the access network device are not limited. Among them, the 5G system can also be referred to as a new radio (NR) system. The access network node in this application can be an access network device, or can be a module or unit configured in the access network device.

[0065] The terminal device provided in the embodiments of this application can also be referred to as a terminal, a user equipment (UE), a mobile station, or a mobile terminal, etc. The terminal can be widely used in various scenarios for communication. Such scenarios include, for example, but are not limited to at least one of the following scenarios: enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), massive machine-type communications (mMTC), device-to-device (D2D), vehicle to everything (V2X), machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, remote medical treatment, smart grid, smart furniture, smart office, smart wearables, smart transportation, or smart city, etc. The terminal can be a mobile phone (such as Figure 1 mobile phones 120a, 120d, 120f in Figure 1 a tablet computer, a computer with wireless transceiver function (such as Figure 1 computer 120g in Figure 1 120b shown), a drone, a helicopter, an airplane (such as Figure 1 120c in ), a ship, a robot, a robotic arm, or a smart home device (such as printer 120e in

[0066] ). In this application, the specific technologies and specific device forms adopted by the terminal are not limited.

[0066] In this application, the terminal can be, for example, the total control terminal of the target area, and can subscribe to a specific type of broadcast service for the target area through communication with the satellite base station. The target area can be, for example, a service area or a geographical area. The terminal can be located within the target area or outside the target area. Among them, the terminal can be an electronic device dedicated to subscribing to a specific type of broadcast service for the target area, or it can be a software system, application program, program code, etc. that can subscribe to a specific type of broadcast service to the satellite base station by deploying on any of the above-mentioned terminal devices, and communicate with the satellite base station through the software system, application program, program code, etc. to subscribe to a specific type of broadcast service for the target area. Among them, when subscribing to a specific type of broadcast service to the satellite base station through a software system or application program, the terminal can log in to the software system or application program. For example, it can be logged in through a preset account. Optionally, if the number of login failures reaches a preset number (for example, 3 times), the account can be blocked and an exception prompt can be output.

[0067] Figure 3 It is a schematic diagram of an initial access process provided by an embodiment of the present application. The following will be combined with Figure 3 to introduce the initial access process involved in the embodiments of the present application.

[0068] The terminal connects to the network through the initial access process. As Figure 3As shown, the initial access process mainly includes the initial synchronization and random access processes. The terminal searches for the synchronization signal (SS) and the physical broadcast channel (PBCH) block (SSB) sent by the network device to obtain frequency synchronization and downlink symbol synchronization. The PBCH carries the master information block (MIB). Based on the MIB, the terminal obtains the relative position relationship between the control resource set 0 (CORESET 0) and the SSB, and thus determines the position of CORESET 0 based on the position of the SSB. The CORESET 0 includes the physical downlink control channel (PDCCH). The PDCCH in the CORESET 0 carries the downlink control information (DCI) for scheduling the system information block 1 (SIB 1). The terminal detects the DCI within the CORESET 0 and receives the SIB1 according to the DCI. The SIB1 is also known as the remaining minimum system information (RMSI). The SIB1 includes cell selection information and cell access related configuration information, etc. The terminal can perform the random access process according to the cell access related configuration information.

[0069] For example, the terminal can perform, according to the cell access related configuration information in the SIB1, such as Figure 3In the 4-step random access procedure shown, the terminal can obtain the configuration of the physical random access channel (PRACH) of the cell according to the cell access-related configuration information in SIB1, and send a random access preamble, i.e., random access message 1 (message 1, Msg1), on the PRACH to the network device, so as to request access to the cell through the random access preamble. If the network device receives Msg1 from the terminal, it can send a random access response (RAR) message to the terminal. The Msg2 may include time advance (TA) information for adjusting time synchronization, temporary cell-RNTI (TC-RNTI), power adjustment information, and uplink grant information for scheduling random access message 3 (Msg3). After receiving Msg2, the terminal can send Msg3 to the network device based on the uplink scheduling information in Msg2. The Msg3 includes the identity information of the terminal and radio resource control (RRC) connection establishment information, etc. After receiving Msg3 from the terminal, the network device can send Msg4 to the terminal. The Msg4 is used for contention resolution, and the network device can notify the terminal of the completion of the random access process through Msg4.

[0070] Figure 3 Taking the example of the terminal performing the 4-step random access process after obtaining initial synchronization, the terminal can also perform the 2-step random access process according to the cell access-related configuration information in SIB1. The 2-step random access process completes the terminal's random access process through two steps: the terminal sends a random access message A (MsgA) to the network device, and the network device sends a random access message B (MsgB) to the terminal. The network device configures the PRACH for carrying Msg1 in MsgA and the physical uplink shared channel (PUSCH) for carrying Msg3 in MsgA in the 2-step random access process through SIB1. The terminal sends MsgA to the network device according to SIB1. After successfully receiving MsgA, the network device can send MsgB to the terminal to notify the terminal of the completion of the random access process. Alternatively, if the network device detects the random access preamble in MsgA but fails to successfully obtain the information in Msg3, the network device can send MsgB to instruct the terminal to fallback to the 4-step random access process.

[0071] Currently, in the NTN architecture, the satellite base station can provide broadcast services for user terminals, and the user terminals can receive the broadcast services broadcast by the satellite base station by subscribing to the broadcast services they need. However, wireless communication resources are limited, and there are significant differences in the requirements for wireless communication resources such as bandwidth and transmission power for different types of broadcast services. For example, for high-definition video broadcasts, a large amount of bandwidth is required to ensure smooth video playback and clear picture quality, and at the same time, a relatively high transmission power is required to ensure stable signal transmission; while for simple text message broadcasts, the requirements for bandwidth and transmission power are relatively low. However, it is currently difficult to reasonably allocate the wireless communication resources used for broadcasts for different types of broadcast services, resulting in problems such as poor quality of broadcast services and resource waste.

[0072] In view of this, the present application provides a communication method. The terminal sends first information to the access network device to request subscribing to a target type of broadcast service for a target area, so that the access network device can accurately learn the demand for broadcast services in the target area. Furthermore, the access network device can determine the expected service area of the target type of broadcast service, and allocate broadcast resources according to the expected service area, thereby improving the rationality of the allocation of wireless communication resources used for broadcasts.

[0073] Figure 4 It is a schematic flowchart of a communication method provided by an embodiment of the present application. As Figure 4 shown, the access network device and the terminal are used for illustration. The access network device and / or the terminal can also be replaced by chips, modules, etc. for executing this method, which is not limited in the present application.

[0074] S401. The terminal sends the first information to the access network device.

[0075] Correspondingly, the access network device receives the first information sent by the terminal.

[0076] Among them, the first information is used to request subscribing to a target type of broadcast service for a target area.

[0077] The target area can be, for example, a geographical area, such as a certain area divided according to geographical administrative regions (such as a certain province / state, a certain city / county urban area, etc.), or it can be a certain area divided according to actual needs (such as the area where the conference venue is located, the logistics hub area, the event coverage area, etc.), etc., which is not limited in the present application.

[0078] The target type can be a non - wide - area broadcast type or a wide - area broadcast type. When the target type is a non - wide - area broadcast type, it can be, for example, a conference broadcast type (such as conference broadcast type I, conference broadcast type II, etc.), a business - secret broadcast type, an emergency - command broadcast type, etc. When the target type is a wide - area broadcast type, it can be, for example, a public - service broadcast type, an entertainment broadcast type, etc.

[0079] Optionally, a broadcast service of a target type may include one or more broadcast services. For example, taking the target type of conference broadcast type I as an example, this target type may include, for example, one or more of a conference - broadcast service, a firmware - upgrade broadcast service, etc.

[0080] Currently, for different broadcast services, the user terminal receiving the broadcast service can subscribe to the Temporary Mobile Group Identity (TMGI) uniquely corresponding to the broadcast service to obtain the permission to receive the broadcast service. When the user terminal subscribes to the TMGI, the network side will create a user session for each user terminal to receive the broadcast service corresponding to the TMGI, and each user session has a unique identifier (for example, Session ID).

[0081] Therefore, the first information request for subscribing to the broadcast service of the target type in the target area can correspond to the broadcast services corresponding to one or more TMGIs.

[0082] After the terminal completes the random - access process, it can send the first information to the access network device to request subscribing to the broadcast service of the target type in the target area. For example, the terminal can send the first information to the access network device by sending a specific signaling carrying the first information. Exemplarily, for example, the terminal can send a registration - request signaling for carrying the first information, or send a NAS signaling carrying the first information, or a custom signaling dedicated to sending the first information, etc., to implement the function of sending the first information to the access network device. Optionally, the registration - request signaling may also include a NAS signaling, and the first information is carried in the NAS signaling.

[0083] Optionally, when the terminal realizes the function of sending the first information to the access network device by sending a NAS signaling carrying the first information, the first information can be carried at any position in the NAS signaling. For example, it can be carried in the NAS container in the NAS signaling, or it can be carried outside the NAS container.

[0084] In a possible implementation, a terminal is in one-to-one correspondence with a target area, that is, one terminal corresponds to one target area. The access network device can determine the target area corresponding to the behavior of subscribing to the first information based on the terminal that sends the first information. In this implementation, the first information can be, for example, request information related to the target type, or information that implicitly represents the request information. For example, the first information may include an identifier corresponding to the target type, such as a code, ID, etc. corresponding to the target type. The access network device can determine that the first information is used to request subscribing to the broadcast service of the target type for the target area according to the identifier of the target type included in the first information.

[0085] In another possible implementation, a terminal can correspond to multiple target areas. In this implementation, the first information can be, for example, request information related to the target area and the target type, or information that implicitly represents the request information. For example, the first information may include an identifier corresponding to the target area and an identifier corresponding to the target type. The identifier corresponding to the target area can be, for example, a code, ID, etc. of the target area; the identifier corresponding to the target type can be, for example, a code, ID, etc. corresponding to the target type. The access network device can determine that the first information is used to request subscribing to the broadcast service of the target type for the target area according to the identifier of the target area and the identifier of the target type included in the first information.

[0086] Exemplarily, the first information may include a first field for requesting subscribing to the broadcast service of the target type for the target area, and this first field is used to indicate the identifier of the target type. The identifier of the target type can be, for example, a broadcast code, and this broadcast code can be set according to actual needs, and different types of broadcast services correspond to different broadcast codes. Exemplarily, Table 1 is a schematic diagram of a broadcast code provided by an embodiment of the present application:

[0087] Table 1

[0088]

[0089] Among them, for different types of broadcast services, the corresponding unique broadcast code can be obtained through a pre-application method. The network side can pre-register or record different types of broadcast services and the corresponding broadcast codes thereof, so as to be able to determine the corresponding type of broadcast service through the broadcast code.

[0090] S402. The access network device sends second information to the terminal.

[0091] Correspondingly, the terminal receives the second information sent by the access network device.

[0092] Among them, the second information is used to indicate whether to agree to subscribe to the broadcast service of the target type for the target area.

[0093] After receiving the first information, the access network device may determine whether to agree to the target area to subscribe to the broadcast service of the target type according to actual requirements. For example, the access network device may determine whether to agree to the target area to subscribe to the broadcast service of the target type based on decision-making factors such as the resource availability of the communication resources used for broadcasting (such as the remaining bandwidth, power redundancy, etc.), service priority, network stability, etc. This application does not limit how the access network device specifically determines whether to agree to the target area to subscribe to the broadcast service of the target type.

[0094] After determining whether to agree to the target area to subscribe to the broadcast service of the target type, the access network device sends the second information to the terminal to indicate whether to agree to the target area to subscribe to the broadcast service of the target type. If the second information indicates agreement for the target area to subscribe to the broadcast service of the target type, the user terminals within the target area can then receive the broadcast service of the target type; if the second information indicates disagreement for the target area to subscribe to the broadcast service of the target type, the user terminals within the target area cannot receive the broadcast service of the target type.

[0095] Specifically, the second information may include a third field indicating whether to agree to the target area to subscribe to the broadcast service of the target type. For example, the third field may include 0 or 1, which is a field indicating whether to agree to the target area to subscribe to the broadcast service of the target type (for example, 0 means disagreement, and 1 means agreement).

[0096] Alternatively, the third field may include the broadcast code corresponding to the target type or a preset value, which is a field indicating whether to agree to the target area to subscribe to the broadcast service of the target type (for example, when the third field includes the broadcast code corresponding to the target type, it represents agreement, and when it includes the preset value, it represents disagreement), etc. Taking the third field including the broadcast code corresponding to the target type or the preset value as an example, the preset value may be any value predefined by the protocol. For example, taking the broadcast code as 000000001 and 000000010, the preset value may be 000000000.

[0097] Optionally, if the terminal sends multiple first information to subscribe to multiple target types of broadcast services for the target area, in order to distinguish whether to agree or disagree to subscribe to which target type of broadcast service, the third field may further include a broadcast code, which is used to indicate whether the second information agrees or disagrees to subscribe to which target type of broadcast service.

[0098] The access network device can send the second information to the terminal by sending a specific signaling carrying the second information. Exemplarily, for example, the access network device can send an SIB signaling carrying the second information to the terminal, or a custom signaling dedicated to sending the second information, etc., to implement the function of sending the second information to the terminal.

[0099] In the method provided by the embodiment of the present application, the terminal sends the first information for requesting to subscribe to the broadcast service of the target type for the target area to the access network device, and the access network device determines whether to agree to the target area to subscribe to the broadcast service of the target type according to the first information, and sends the second information for indicating whether to agree to the target area to subscribe to the broadcast service of the target type to the terminal. When agreeing that the target area subscribes to the broadcast service of the target type, the user terminals in the target area are allowed to receive the broadcast service of the target type, so that the access network device determines the expected service area of the broadcast service of the target type, which is convenient for allocating broadcast resources according to the expected service area, thereby improving the rationality of the allocation of the wireless communication resources used for broadcasting. Moreover, this method can provide the network operator with the expected service area of the broadcast service, so that the network operator can more efficiently and accurately perform network planning behaviors such as satellite beam pointing adjustment and transmit power adjustment according to the expected service areas corresponding to different types of broadcast services, and effectively manage the user distribution and broadcast service requirements in different regions.

[0100] Figure 5 It is a schematic flowchart of another communication method provided by the embodiment of the present application. As Figure 5 shown, this method may include:

[0101] S501. The terminal sends the first information to the access network device.

[0102] Correspondingly, the access network device receives the first information sent by the terminal.

[0103] Among them, the first information is also used to indicate the identity information of the terminal to ensure network security and prevent malicious terminals from maliciously subscribing to broadcast services. Among them, the identity information of the terminal can be indicated, for example, by one or more of the identifier of the terminal, a predefined key, etc. Among them, the identifier of the terminal can include, for example, a hardware identifier (such as an International Mobile Equipment Identity (IMEI), a Media Access Control Address (MAC), a device code of the terminal, etc.), a network identifier (such as an Internet Protocol (IP) address, a network port number, etc.), a software identifier (such as a software ID, an application signature, etc.).

[0104] In one embodiment, the first information may further include a second field, and this second field is used to indicate the identity information of the terminal. For example, the second field includes the identifier of the terminal, a key, etc. to indicate the identity information of the terminal.

[0105] Optionally, the content included in the second field may be uniquely corresponding to the identity information of the terminal, that is, the identity information of one terminal corresponds to one piece of content. The access network device can determine the identity information of the unique terminal according to the content of the second field. Alternatively, the second field has an association relationship with the first field, that is, the identity information of the terminal is in one-to-one correspondence with the first field. For example, when terminal 1 requests to subscribe to the broadcast service of target type 1 for the target area, it needs to send identity information 1 (such as key 1); when terminal 1 requests to subscribe to the broadcast service of target type 2 for the target area, it needs to send identity information 2 (such as key 2). Or, when terminal 1 requests to subscribe to the broadcast service of target type 1 for target area 1, it needs to send identity information 3 (such as key 3); when terminal 1 requests to subscribe to the broadcast service of target type 1 for target area 2, it needs to send identity information 4 (such as key 4), etc.

[0106] S502. The access network device verifies the identity information of the terminal.

[0107] If the identity information verification is passed, it indicates that the identity of the terminal is legal or the first information sent is legal information. The access network device can agree to the subscription of the broadcast service of the target type for the target area and execute step S503; if the identity information verification fails, it indicates that the identity of the terminal is illegal or the first information sent is illegal information. The access network device rejects the subscription of the broadcast service of the target type for the target area and executes step S504.

[0108] Among them, the access network device prestores the identity information of multiple terminals, so that after receiving the first information, it can verify the terminal based on the prestored identity information. For example, it can be verified by determining whether the identity information of the terminal included in the first information is the identity information in the identity information of the terminals prestored by the access network device. If so, the identity information verification is passed; if not, the identity information verification fails. Alternatively, it can also be verified by combining whether the format of the identity information of the terminal included in the first information meets the preset format requirements. Or, it can also calculate the identity information of the terminal included in the first information according to the preset rules, and determine whether the verification is passed according to the calculation result, etc.

[0109] Exemplarily, taking the identity information of the terminal as the terminal ID as an example, the access network device pre-stores a list of legitimate terminal IDs. After the terminal sends the first information containing the terminal ID to the access network device, the access network device can extract the terminal ID from the first information. Assume that the list of legitimate terminal IDs pre-stored by the access network device is [1001, 1002, 1003]. If the terminal ID contained in the first information is 1002, the extracted terminal ID (1002) can be compared with the pre-stored list of legitimate terminal IDs. Since 1002 is included in the list of legitimate terminal IDs, the identity information of the terminal is considered legitimate and the verification passes; if the terminal ID contained in the first information is 1004, since 1004 is not included in the pre-stored list of legitimate terminal IDs, the identity information of the terminal is considered illegitimate and the verification fails.

[0110] Exemplarily, taking the identity information of the terminal as the key as an example, the key can be related to one or more of the identity information of the terminal, the target area, and the target type. For example, when terminal 1 subscribes to the subscription service of target type 1 for target area 1, it needs to carry key 1 in the first information; when terminal 1 subscribes to the subscription service of target type 2 for target area 1, it needs to carry key 2 in the first information; when terminal 1 subscribes to the subscription service of target type 1 for target area 2, it needs to carry key 3 in the first information; when terminal 1 subscribes to the subscription service of target type 2 for target area 2, it needs to carry key 4, etc.

[0111] The access network device can pre-store all legitimate keys. Assume that the legitimate key pre-stored by the access network device for terminal A to subscribe to the broadcast service of target type 1 is abcdef123456. When terminal A sends the first information to the access network device, the access network device extracts the key abcdef123456 from it and compares it with the pre-stored key corresponding to this terminal. If the two are the same, the identity information of the terminal is legitimate and the verification passes; otherwise, the verification fails.

[0112] Exemplarily, taking the identity information of the terminal as the terminal ID and the key as an example, the verification can be performed by combining the implementation method where the identity information of the terminal includes the terminal ID and the implementation method where the identity information of the terminal includes the key, which will not be elaborated here.

[0113] S503. The access network device sends the second information consenting to the terminal to subscribe to the broadcast service of the target type in the target area to the terminal.

[0114] Correspondingly, the terminal receives the second information consenting to the terminal to subscribe to the broadcast service of the target type in the target area sent by the access network device.

[0115] In this step, the content included in the second information and the manner of sending the second information may refer to the second information in the foregoing step S402 for agreeing to subscribe to the broadcast service of the target type in the target area, which will not be elaborated here.

[0116] S504. The access network device sends the second information indicating disagreement to subscribe to the broadcast service of the target type in the target area to the terminal.

[0117] Correspondingly, the terminal receives the second information sent by the access network device indicating disagreement to subscribe to the broadcast service of the target type in the target area.

[0118] In this step, the content included in the second information and the manner of sending the second information may refer to the second information in the foregoing step S402 for disagreeing to subscribe to the broadcast service of the target type in the target area, which will not be elaborated here.

[0119] Optionally, when the access network device disagrees to subscribe to the broadcast service of the target type in the target area, the terminal may resend the first information to the access network device to re-request to subscribe to the broadcast service of the target type in the target area, and re-execute the methods of the foregoing steps S401 - S402 or S501 - S504.

[0120] Optionally, the access network device may also limit the number of times the terminal requests to subscribe to the broadcast service of the target type in the target area according to a preset request times threshold. For example, taking the request times threshold as 3, if the terminal continuously requests to subscribe to the broadcast service of the target type in the target area 3 times and the access network device disagrees to subscribe to the broadcast service of the target type in the target area each time, the access network device may prohibit the terminal from requesting to subscribe to the broadcast service of the target type in the target area again, and / or block the terminal (or block the account of the terminal), and / or output an alarm prompt (for prompting that the terminal has failed in multiple requests and there is a risk), etc.

[0121] It should be understood that the implementation manners of the foregoing steps S501 - S504 can be applied to non - wide - area broadcast types and can also be applied to wide - area broadcast types.

[0122] In the method provided in the embodiment of the present application, the terminal sends the first information capable of indicating the identity information of the terminal to the access network device, and the access network device verifies the identity information of the terminal. If the verification is passed, it agrees to subscribe to the broadcast service of the target type in the target area; if the verification fails, it refuses to subscribe to the broadcast service of the target type in the target area. Moreover, the access network device informs the terminal whether it has successfully subscribed to the broadcast service of the target type in the target area by sending the second information indicating agreement or disagreement to subscribe to the broadcast service of the target type in the target area. This method verifies the identity information of the terminal, reduces the probability of illegal terminals maliciously subscribing to broadcast services, and thus improves the security of the terminal's request to subscribe to the broadcast service of the target type in the target area.

[0123] In a possible implementation, after the access network device sends the second information to the terminal, the terminal may further send third information to the access network device. The third information is used to indicate that the terminal has successfully received the second information, so as to inform the access network device that the terminal has successfully received the second information.

[0124] In this implementation, the terminal may send the third information to the access network device only when the second information indicates consent to subscribe to the broadcast service of the target type in the target area, so as to inform the access network device that the terminal has successfully received the consent to subscribe to the broadcast service of the target type in the target area. Alternatively, regardless of whether the second information indicates consent to subscribe to the broadcast service of the target type in the target area, the terminal may send the third information to the access network device, so as to inform the access network device that the terminal has successfully received the second information.

[0125] Optionally, when the second information indicates consent to subscribe to the broadcast service of the target type in the target area, the terminal may carry the content of the foregoing first field, such as the foregoing broadcast code, in the third information, and then send the third information to the access network device, so as to inform the access network device that the terminal has received the consent to subscribe to the broadcast service of the target type in the target area. The access network device may then determine the target type in the content indicated by the third information based on the broadcast code.

[0126] Among them, the foregoing third information may be sent through any signaling, signal, or message carried on the uplink channel between the terminal and the access network device. The uplink channel may be, for example, a Physical Uplink Control Channel (PUCCH).

[0127] In a possible implementation, the access network device may also perform secondary verification on the identity information of the terminal during the process of providing the broadcast service of the target type. If the secondary verification is passed, the broadcast service of the target type for the target area is continued; if the secondary verification fails, the subscription to the broadcast service of the target type for the target area is cancelled.

[0128] Optionally, if the secondary verification fails, on the basis of cancelling the subscription to the broadcast service of the target type for the target area, the access network device may further feedback the situation that the secondary verification fails. For example, the access network device may also send information indicating that the secondary verification fails to the terminal, so that the terminal may resend the identity information of the terminal for secondary verification, or indicate that the subscription to the broadcast service of the target type for the target area by the terminal has been cancelled, etc.

[0129] Optionally, the access network device may perform one or more secondary validations on the identity information of the terminal during the process of providing the target type of broadcast service, and the moment of the secondary validation may be set according to actual requirements. For example, the access network device may perform one or more secondary validations on the identity information of the terminal periodically during the process of providing the target type of broadcast service, and the period of the secondary validation may be set according to actual requirements. For example, a secondary validation may be performed at intervals of a preset duration. Among them, the period of the secondary validation, or the preset duration, or the moment of the secondary validation, etc. may be predefined by the protocol; or, it may be determined by the access network device and sent to the terminal in advance; or, it may also be carried by the terminal when sending the first information, etc.

[0130] Specifically, the terminal may actively send a fourth message to the access network device at the moment when secondary validation is required, and the access network device receives the fourth message sent by the terminal. Among them, the fourth message is used to indicate the identity information of the terminal for secondary validation. The identity information of the terminal for secondary validation is the same as the identity information of the terminal indicated by the foregoing first message. For example, the fourth message may include a fourth field, and the fourth field is used to indicate the identity information of the terminal for secondary validation. How the fourth field indicates the identity information of the terminal for secondary validation may reuse the implementation manner of how the first message indicates the identity information of the terminal in the second field, which will not be elaborated here. For example, the fourth field includes the identity information of the terminal.

[0131] Optionally, the fourth message may also be used to indicate the broadcast code corresponding to the target type of broadcast service, so as to inform the access network device which type of broadcast service the secondary validation is for this time, so as to facilitate the access network device to perform secondary validation on providing the target type of broadcast service for the target area. For example, the fourth message may include a fifth field, and the fifth field is used to indicate the broadcast code corresponding to the target type of broadcast service, that is, the content in the fifth field includes the broadcast code corresponding to the target type of broadcast service.

[0132] Or, the access network device may first send a fifth message to the terminal at the moment when secondary validation is required. After receiving the fifth message, the terminal sends a fourth message to the access network device in response to the fifth message. Among them, the fifth message is used to request the identity information of the terminal for secondary validation, that is, to request the terminal to send the identity information of the terminal for secondary validation to the access network device. Specifically, the fifth message may include a sixth field, and the sixth field is used to request the identity information of the terminal for secondary validation.

[0133] Optionally, the fifth piece of information may also be used to indicate the broadcast code corresponding to the broadcast service of the target type, so that the terminal can know which type of broadcast service the fifth piece of information requests the identity information of the terminal required for secondary verification. Based on the broadcast code indicated by the fifth piece of information, the terminal determines which type of broadcast service's secondary verification required identity information of the terminal needs to be carried in the fourth piece of information sent to the access network device subsequently. For example, the fifth piece of information may further include a seventh field, and the seventh field is used to indicate the broadcast code corresponding to the broadcast service of the target type (such as the broadcast code is included in the content of the seventh field).

[0134] In the method provided by the embodiments of the present application, during the process of providing the broadcast service of the target type, the access network device performs secondary verification on the identity information of the terminal. If the secondary verification is passed, the access network device continues to provide the broadcast service of the target type for the target area. If the secondary verification fails, the subscription of the broadcast service of the target type in the target area is cancelled. Thereby, the security of the broadcast service is enhanced, illegal terminal access is effectively prevented, and problems such as malicious attacks or information leakage are avoided. Moreover, the expected service area of the broadcast service of the target type can be further screened through secondary verification, and the subscription of the target area where the secondary verification fails is cancelled, ensuring that the broadcast content is only received by the user terminals in the authorized target area, so as to ensure that the broadcast resources are not wasted on illegal devices, enabling legal terminals to obtain a more stable and efficient service experience, and improving the rationality of the allocation of broadcast resources.

[0135] In a possible implementation manner, a broadcast service of a target type may include multiple broadcast services. Currently, for different broadcast services, the user terminal receiving the broadcast service can subscribe to the TMGI uniquely corresponding to the broadcast service to obtain the permission to receive the broadcast service. When the user terminal subscribes to the TMGI, the network side creates a user session for each user terminal to receive the broadcast service corresponding to the TMGI, and each user session has a unique identifier (such as Session ID).

[0136] After the target area successfully subscribes to the broadcast service of the target type, the user terminals corresponding to the target area (such as the user terminals located in the target area, or the user terminals not located in the target area but associated with the target area, etc.) have the permission to receive the broadcast service of the target type. Therefore, during the process of the access network device providing the broadcast service of the target type for the target area, the user terminals corresponding to the target area can receive each broadcast service included in the broadcast service of the target type without subscribing to the TMGI of each broadcast service included in the broadcast service of the target type. Specifically, the user terminals corresponding to the target area can have the permission to receive each broadcast service included in the broadcast service of the target type, and can select the broadcast services belonging to the broadcast service of the target type that need to be received according to actual needs.

[0137] The method provided by the embodiment of the present application enables the user terminal corresponding to the target area to receive each broadcast service belonging to the target type of broadcast service without subscribing to each broadcast service belonging to the target type of broadcast service, that is, without subscribing to the TMGI corresponding to the broadcast service, by subscribing to the broadcast service of the target type for the target area, thereby reducing the operation process of the user terminal subscribing to the broadcast service and improving the service efficiency of the broadcast service.
