[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410403822.8 filed in China on April 3, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The embodiments of the present application relate to the field of wireless communication technologies, and in particular to an operating method, apparatus, communication equipment, storage medium, and program product. Background Art

[0004] In the existing network, in order to meet the intelligent needs of the Internet of Things, the Ambient Internet of Things (AIoT) has been introduced, also known as the Ambient power-enabled Internet of Things (Ambient power-enabled IoT), which is an Internet of Things (IoT) service. A terminal such as an AIoT device is a low-power IoT device. The overall power consumption of this type of device is low, including low-power signal reception and low-power signal transmission. Due to the low overall power consumption, the energy for communication can come from the environment, such as wind energy, kinetic energy, thermal energy, radio frequency (RF) signals, etc. AIoT devices can also be described as passive IoT devices or answering devices. AIoT devices are usually in a non-Radio Resource Control (RRC) state and do not perform mobility management.

[0005] For operations on passive terminal devices, such as inventory, a communication device (such as a reader) needs to operate one or more AIoT devices. AIoT devices are often passive and numerous, requiring the communication device to sequentially send operation commands for the AIoT devices to respond. For a single operation, the communication device may only be able to interact with N terminals simultaneously, so it cannot process the N+1 terminal until the operation on one terminal is completed.

[0006] Therefore, how to determine whether the operation on the terminal is completed and the interaction with the terminal is completed is a problem that needs to be solved at present. Summary of the Invention

[0458] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0459] The term "comprise" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to the process, method, product, or apparatus. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and both A and B are included.

[0460] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0461] The technology described in this article is not limited to the fifth-generation mobile communication (5th-generation, 5G) system and subsequent evolution communication systems, and is not limited to the long-term evolution (Long Term Evolution, LTE) / LTE's evolution (LTE-Advanced, LTE-A) system, and can also be used in various wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA) and other systems.

[0462] The terms "system" and "network" are often used interchangeably. A CDMA system can implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). UTRA includes Wideband Code Division Multiple Access (WCDMA) and other CDMA variants. A TDMA system can implement radio technologies such as Global System for Mobile Communication (GSM). An OFDMA system can implement radio technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (Evolution-UTRA, E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and Flash-OFDM. UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). LTE and more advanced LTE (such as LTE-A) are new versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies.

[0463] Problem 1: In some interactions with terminals (such as AIoT devices), such as information transmission between AIoT devices and core network (CN) devices (such as AIoT functions), the reader is only responsible for forwarding information and has no idea whether the currently forwarded information is the last one. The reader is unaware that the interaction with an AIoT device has ended or there are further interactions required. Therefore, the reader does not know when to move on to the next AIoT device.

[0464] When a user equipment (UE) connects to a base station, a per-UE association is established between the base station and the CN device. Each UE association is independent. Furthermore, releasing or suspending this association causes the UE to transition from a connected state to a disconnected state. However, AIoT devices do not have RRC states, and therefore do not distinguish between connected and disconnected states.

[0465] Question 2: The first AIoT device may also need to know that the first AIoT device has ended. There is also an upper limit on the number of operation sessions (or processes) that an AIoT device can respond to simultaneously. For example, if there are multiple operation sessions that require the first AIoT device to operate. If the first AIoT device can only respond to four operation sessions simultaneously and all four operation sessions are in progress, the first AIoT device can only switch to responding to the fifth operation session after at least one of the sessions has ended.

[0466] Question 3: The number of target objects represents the number of first terminals that can interact simultaneously. For example, M target identifiers are assigned to the first object to establish M target associations. When a new first terminal is discovered or interaction with the first terminal is required, the first communication device can bind the first terminal to an idle target association or target identifier. Through the bound target association or target identifier, the interaction of information related to the first terminal can be associated, guaranteed and / or supported. Once the interaction with the first terminal is completed, the binding with the target association or target identifier can be released.

[0467] Through the above method, at least one of the first, second, and third communication devices can exchange information about up to M AIoT devices. For example, M = 20, which corresponds to 20 pipelines. For example, 1,000 AIoT devices can complete information exchange between the reader and the core network through these 20 pipelines.

[0468] The communication device also needs to know that the first terminal has ended its call to release the resources occupied by the first terminal.

[0469] The following describes solutions to the above problems.

[0470] Solution 1: The CN device (such as AIoT function) determines the termination process of the first AIoT device.

[0471] Option 1: When it is determined that the first AIoT device has terminated (e.g., the information received from the first AIoT device is the last information, or the AF indicates the termination of interaction with the first AIoT device), a message indicating the termination of interaction with the first AIoT device is sent to the reader. (The termination of interaction with the first AIoT device includes at least one of the following: termination of operation on the first AIoT device, termination of interaction with the first AIoT device)

[0472] Option 1.1: When a first AIoT device is bound to a first object (first association or first identifier), a message is sent to the reader requesting the release of the association and / or context of the first AIoT device. The first association or first identifier is an object used to associate the AIoT device between the reader and the CN device.

[0473] Option 1.2 sends an end indication + the identifier of the first AIoT device.

[0474] Furthermore, a first session identifier or an identifier of a first operation is also sent.

[0475] Option 2: When it is determined that the information of the AIoT device to be sent is the last piece of information, the first AIoT device sends the information to the reader and indicates that the information is the last piece of information.

[0476] After the reader / writer completes sending the information to the CN device based on the information, it can also indicate to the CN device that this is the last piece of information.

[0477] CN is used to determine whether the first AIoT device has ended.

[0478] Solution 2: The reader triggers the termination process of the first AIoT device.

[0479] Option 1: When it is determined that the information sent to the AIoT device is the last downlink information, the CN sends the information to the reader and indicates that the information is the last information sent to the first AIoT device.

[0480] After the reader / writer completes sending the information to the first AIoT device based on the information, it can send information to the CN device to indicate the end of the first AIoT device.

[0481] Option 1.1: When a first AIoT device is bound to a first object (first association or first identifier), the reader unbinds the first AIoT device from the first object. The first association or first identifier is used to associate the AIoT device between the reader and the CN device.

[0482] Option 1.2: Sending end indication + identification of the first AIoT device.

[0483] Furthermore, a first session identifier or an identifier of a first operation is also sent.

[0484] Option 2: If the reader no longer receives information from the CN that needs to be sent to the first AIoT device, or no longer receives information from the first AIoT device, the reader can also determine that the first AIoT device has ended, and can send information to the CN device to indicate the end of the first AIoT device.

[0485] Solution three: The first AIoT device triggers the termination process of the first AIoT device.

[0486] Option: When the first AIoT device is determined to have terminated (e.g., the last message received from the reader or the CN), a message indicating the termination of the first AIoT device is sent to the reader or the CN. (The termination of the first AIoT device includes at least one of the following: termination of operation on the first AIoT device, termination of interaction with the first AIoT device)

[0487] The reader / writer is used to indicate the end of the first AIoT device based on the information.

[0640] In one embodiment, backscatter or communication without active signal generation capability means backscattering on an externally provided carrier.

[0641] In one implementation, the active signal generation refers to the terminal itself generating a signal.

[0642] Optionally, the first interface can be implemented in the following ways: Method 1, reusing the NG interface, for example, the base station supports both terminal (new uu interface) communication and UE (traditional uu interface) communication, and adding a new IE to the mandatory information of the NG interface; Method 2, reusing the NG interface, but for example, the base station only supports the terminal (new uu interface), at this time, a new instruction can be added to ignore the mandatory IE that already exists but is not applicable to the terminal, such as Default Paging DRX; Method 3, introducing a new interface, such as a second NG interface.

[0643] 2.5 Second Interface

[0644] In an optional embodiment of the present invention, the second interface is a wireless interface between the "first communication device or reader / writer" and the terminal. In one embodiment, the second interface may be another air interface different from the Uu interface or the PC5 interface. In another embodiment, the second interface may be an enhancement of the Uu interface or the PC5 interface.

[0645] 2.6 Information used to indicate and / or filter terminals

[0646] In one embodiment of the present application, information used to indicate and / or filter terminals (such as information used to indicate and / or filter AIoT devices) can be used to indicate and / or filter one or more terminals (such as AIoT devices).

[0647] The information used to indicate and / or screen terminals includes at least one of the following: a terminal identifier, an identifier for identifying a group of terminals (referred to as a group identifier), matching information, and information for indicating characteristics of the terminal.

[0648] In one embodiment of the present application, the information used to indicate and / or filter terminals includes a terminal identifier. In this case, a terminal identifier can be used to specifically refer to a single terminal. Multiple terminal identifiers can be used to specifically refer to multiple terminals. It is understood that a terminal identifier can uniquely identify the terminal and is not shared by other terminals.

[0649] In one embodiment of the present application, the information used to indicate and / or filter terminals includes an identifier for identifying a group of terminals (referred to as a group identifier). In this case, a group identifier can specifically refer to a group of terminals. It is understood that a terminal group identifier can uniquely identify the terminal group and is not shared by other terminal groups.

[0650] In one embodiment of the present application, the information used to indicate and / or filter terminals may not include terminal identifiers. The information used to indicate and / or filter terminals may include matching information (which may not include terminal identifiers). The matching information may not be unique to each terminal, but may apply to a group of terminals (i.e., one or more terminals). Furthermore, the number of terminals in this group may be uncertain. For example, the identification of the terminal can only be determined after the terminal has feedback. When a terminal has the matching information or information corresponding to the matching information, the terminal can be considered the target terminal (i.e., the terminal that successfully matches the information used to indicate and / or filter terminals, the terminal of the first operation).

[0651] For example, in step 1, the terminal stores matching information, such as "AAA", and the terminal also stores "AAA", which indicates a successful match. It is easy to understand that there may be multiple terminals that store "AAA".

[0652] For example, in case 2, the terminal stores information corresponding to the matching information (which may be different from the matching information, but corresponds to the matching information). For example, if the matching information is "AAA" and the terminal stores "BBB", since AAA and BBB have a corresponding relationship, this is also a successful match. It is not difficult to understand that there may be multiple terminals storing "BBB".

[0653] In another embodiment, the information used to indicate and / or filter terminals includes a terminal identifier. In this case, a terminal identifier can be used to specifically refer to a single terminal. Multiple terminal identifiers can be used to specifically refer to multiple terminals. It is understood that a terminal identifier uniquely identifies the terminal and is not shared by other terminals.

[0654] 4: In one embodiment of the present application, the information used to indicate and / or screen terminals includes information used to indicate characteristics of the terminals. Since different terminals have different characteristics, the information used to indicate the characteristics of the terminals can play a role in indicating and / or screening terminals.

[0655] 2.7 Object requesting the first operation

[0656] Optionally, the object requesting the first operation refers to: a requester requesting the first operation (also referred to as a client. The requester may be a certificate holder (such as a certificate holder of an AIoT device)). The object requesting the first operation may be one or more.

[0657] In one implementation, the object may be referred to as one of the following: client, owner, owner, certificate holder (such as a certificate holder of a terminal).

[0658] 2.8 Service Area

[0659] In one embodiment of the present application, the service area or supported service area is at least one of the following: an area providing AIoT services, an area communicating with a terminal (such as an area for direct communication), and an area supporting AIoT operations.

[0660] In one embodiment, the AIoT service can realize the operation requirements of the client, network or reader on the terminal (such as the first operation).

[0661] In one embodiment, the supported service area is different from the TA list supported by the existing RAN device. Therefore, the supported service area can be represented by additional area information (i.e., area information different from the TA). Alternatively, the currently supported TA list (such as the supported TAList in the existing NG interface request message) is understood as the first TA, and the supported service area is understood as the second TA. When the RAN device supports communication with the UE and the terminal at the same time, the first TA list and the second TA list can be provided at the same time. The second TA list is different from the first TA list. When the RAN device supports communication with the terminal, a second TA list can be provided. That is, the information used to indicate the supported service area can be the second list.

[0662] 2.9 Information about the Xth communication device

[0663] Optionally, the information of the Xth communication device includes at least one of the following: an identifier of the Xth communication device, an address of the Xth communication device, and information used to index the Xth communication device (such as FQDN, which can be used to index the address of the communication device).

[0664] Optionally, the Xth communication device includes at least one of the following: a first communication device, a second communication device, a third communication device, and a fourth communication device.

[0665] 2.10 Intermediary Devices

[0666] A first communication device (such as a reader / writer) can communicate directly with a terminal or through an intermediate device. Sometimes, the first communication device is far from the terminal, and the first communication device can extend the reader / writer's coverage area through an intermediate device. In this case, the intermediate device is also called a reader / writer or a component of the reader / writer.

[0667] In one embodiment, the intermediate device may be an intermediate node located between the terminal 11 and other devices (such as access network devices or reader / writers), but is not limited thereto. The intermediate device may expand the coverage of the other devices or facilitate communication between the terminal 11 and other network devices (such as access network devices or reader / writers), but is not limited thereto.

[0878] Requesting to terminate the operation on the first terminal;

[0879] Request to end interaction with the first terminal.

[0880] The number of target objects mentioned above represents the number of first terminals that can interact simultaneously. For example, M target identifiers are allocated to the first object to establish M target associations. When a new first terminal is discovered or interaction with the first terminal is required, the first communication device can bind the first terminal to an idle target association or target identifier. Through the bound target association or target identifier, the interaction of information related to the first terminal can be associated, guaranteed and / or supported. Once the interaction with the first terminal is completed, the binding with the target association or target identifier can be released.

[0881] Through the above method, at least one of the first, second, and third communication devices can exchange information about up to M AIoT devices. For example, M = 20, which corresponds to 20 pipelines. For example, 1,000 AIoT devices can complete information exchange between the reader and the core network through these 20 pipelines.

For example, when the destination of the last information related to the first terminal is the first communication device, the first terminal can be determined to have ended when the last information related to the first terminal has been obtained.

[1017] The interval time between sending two consecutive downlink information to the first terminal.

[1018] In one implementation, the two consecutive pieces of information related to the first terminal mean that no other information related to the first terminal exists between the two pieces of information related to the first terminal.

[1019] It is not difficult to understand that two consecutive “information related to the first terminal” need to be determined from two directions, that is, the two consecutive “information related to the first terminal” may come from different directions.

[1020] In some embodiments, the first target device includes one of the following: a second communication device, a second communication device.

[1021] In some embodiments, the first timer may be locally configured or received from the second communication device or the third communication device.

[1022] In some embodiments, optionally, the first behavior further includes: sending fifth information to at least one of the second communication device and the third communication device together with sending the third information to at least one of the second communication device and the third communication device.

[1023] Alternatively, when the second information is sent to the fourth communication device, information indicating the end of the first terminal is also sent to the fourth communication device.

[1024] In one embodiment, when sending third information to at least one of the second communication device and the third communication device, five information are sent to the second communication device together through the same signaling, message, cell or data, such as at least one of the following: information for indicating the end of the first terminal, information for indicating a request to end the first terminal, information for requesting to release the binding of the first terminal from the target object, information for indicating that the binding of the first terminal from the target object has been released, and information for indicating a request to release at least one of the association, context and resources of the first terminal.

[1025] In one embodiment, when the second sub-operation is performed, information indicating the end of the first terminal is sent to the fourth communication device through the same signaling, message, cell or data.

[1026] In some embodiments, the first terminal is a terminal associated with the first object or the first terminal associated with the first object;

[1027] Alternatively, the operation on the first terminal ends, including: the operation on the first terminal of the first object ends;

[1028] Alternatively, the termination of the interaction with the first terminal includes: termination of the interaction with the first terminal of the first object;

[1029] Alternatively, requesting to end the operation on the first terminal includes: requesting to end the operation on the first terminal related to the first object;

[1030] Alternatively, requesting to end the interaction with the first terminal includes: requesting to end the interaction of the first terminal related to the first object;

[1031] The first object includes at least one of the following: a first service, a first operation, and a first session.

[1032] In one implementation, the terminal related to the first object (eg, the first terminal) is, for example, the first terminal determined by the information of the first object used to indicate and / or filter terminals.

[1033] In one embodiment, when information related to a first terminal (such as information from the first terminal or information to the first terminal) carries a first identifier (such as an identifier of a first object), it can be determined that the first terminal is a terminal related to the first object (referred to as a first object-related terminal for short).

[1034] The terminal related to the first object may be simply referred to as the terminal of the first object.

[1035] The first terminal related to the first object may be simply referred to as the first terminal of the first object.

[1036] The first object includes one of the following: a first service, a first operation, a first session;

[1037] In one scenario, there may be multiple first terminals associated with the first object, and operations on different first terminals associated with the first object, or interactions with different first terminals associated with the first object, are terminated separately.

[1038] In another scenario, a terminal can be a terminal associated with at least one first object. Operations on the same terminal by different first objects, or interactions with the same terminal by different first objects, are terminated separately. Therefore, the termination of an operation associated with first object A on a terminal does not affect operations associated with first object B on the terminal.

[1039] Therefore, the operation related to the first object A with one terminal is completed, and the operation of the first object B with the terminal is not affected.

[1040] It is easy to understand that the termination of the first terminal refers to the termination of an operation on a terminal related to a first object, or the termination of an interaction between a first object and a terminal.

[1041] The first object includes one of the following: a first service, a first operation, a first session;

[1042] The first terminal associated with the first object may be referred to as the first terminal of the first object. In one embodiment, the information sent by the first terminal of the first object includes a first identifier (e.g., an identifier of the first object). For example, if the response from the first terminal includes the first identifier, it indicates that the first terminal is the first terminal of the first object.

[1043] The first terminal may be the first terminal of one or more first objects. Different first objects are terminated separately.

[1044] For example, the first identifier of the first object A is A, and the first identifier of the first object B is B. If the response of the first terminal contains the first identifier A but does not contain the first identifier B, then the first communication device can determine that the first terminal of the first object A is found, or determine that the first terminal of the first object B is not found.

[1045] The first terminal is a first terminal related to the first object. For example, the first terminal is a first terminal determined according to information in the first object for indicating or filtering the first terminal.

[1046] In one embodiment, the information used to indicate or filter the first terminal includes at least one of the following:

[1047] One or more identifiers for identifying a single first terminal;

[1048] One or more identifiers for identifying the first terminal group;

[1049] Used to filter the information of the first terminal.

[1050] In one embodiment, the information used to screen the first terminals is different from or does not include at least one of the following: an identifier of the first terminal (e.g., an identifier of a single first terminal, i.e., an identifier used to identify a single first terminal) and an identifier of the first terminal group.

Information from the first terminal can be carried in a container. The container can be transparent to the first communication device, which sends the information to the second communication device.

[1328] The first uplink information is obtained, or the first uplink information has been sent;

[1329] The first downlink information is obtained or the first downlink information has been sent;

[1330] Downlink information is obtained, or downlink information has been sent, where the downlink information satisfies at least one of the following: it is the last information sent to the first terminal, the downlink information does not require a response, and it is the last information related to the first terminal;

[1331] Acquiring uplink information, or having sent uplink information, where the uplink information satisfies at least one of the following: being the last information from the first terminal, the uplink information does not require a response, and is the last information related to the first terminal;

[1332] Downlink information is obtained or has been sent; the downlink information satisfies one of the following: downlink information subsequent to uplink information or a response to uplink information; the uplink information satisfies at least one of the following: the last information from the first terminal, the uplink information requires a response, and is the last information related to the first terminal;

[1334] completing an operation on the first terminal, or completing an interaction with the first terminal;

[1335] The second timer times out.

[1336] In one embodiment, the last information related to the first terminal is obtained, or the last information related to the first terminal has been sent; for example, when the destination of the last information related to the first terminal is the first communication device, then when the last information related to the first terminal is obtained, it can be determined that the first terminal has ended. For example, when the destination of the last information related to the first terminal is not the first communication device, it can be determined that the first terminal has ended only when the last information related to the first terminal has been sent. The same applies to other first uplink information and first downlink information, which will not be repeated here.

[1337] In one embodiment, the last piece of information related to the first terminal is one of the following:

[1338] The last message to the first terminal, the downlink message does not require a response;

[1340] In one embodiment, acquiring information indicating the termination of the first terminal includes: receiving information indicating the termination of the first terminal from the first communication device, from at least one of the fourth communication device and the third communication device.

[1342] In one implementation, obtaining the fifth information includes receiving the fifth information from at least one of the first communication device and the third communication device.

[1343] In one scenario, a second communication device exchanges information (at least one of uplink and downlink information) about the first terminal with a fourth communication device (e.g., the first terminal). The first communication device is responsible for relaying the information, so it's unclear whether the relayed information is the final information or whether the relayed information requires a response or further interaction. Therefore, it's understandable that it's inaccurate for the first communication device to determine that the first terminal has terminated the communication. However, it's more accurate for the second communication device and the fourth communication device (e.g., the first terminal) to determine that the first terminal has terminated the communication.

[1344] In one scenario, a third communication device and a fourth communication device (e.g., a first terminal) exchange information about a first terminal. The first communication device and / or the second communication device are responsible for relaying the information. It is inaccurate for the first communication device and / or the second communication device to determine that the first terminal has terminated the call. However, it is more accurate for the second communication device and the fourth communication device (e.g., the first terminal) to determine that the first terminal has terminated the call.

[1345] In one scenario, a first communication device exchanges information about a first terminal with a third communication device, with the second communication device acting as the intermediary. It would be inaccurate for the second communication device to determine that the first terminal has terminated. However, it would be more accurate for the first communication device and the third communication device to determine that the first terminal has terminated.

[1383] In one embodiment, the termination of the interaction with the first terminal indicates that the interaction between at least one of the first communication device, the second communication device, and the third communication device and the first terminal is terminated.

[1421] The interval between the reception times of two consecutive pieces of information related to the first terminal is shown in FIG6D . The interval between the reception times of two consecutive pieces of information related to the first terminal includes at least one of the following:

[1422] The interval between the time when downlink information is sent to the first terminal and the time when uplink information sent by the first terminal is received; the downlink information and the downlink information are two consecutive pieces of information related to the first terminal;

[1425] The interval time between sending two consecutive downlink information to the first terminal.

[1426] In one implementation, sending a downlink message to start timing includes sending downlink information to the first communication device to start timing.

[1427] Sending an uplink message to start timing includes, for example, sending a downlink message to the first target device to start timing.

[1428] The starting of timing upon receiving uplink information includes starting of timing upon receiving uplink information from the first communication device.

[1429] In one implementation, the two consecutive pieces of information related to the first terminal mean that no other information related to the first terminal exists between the two pieces of information related to the first terminal.

[1430] It is not difficult to understand that two consecutive “information related to the first terminal” need to be determined from two directions, that is, the two consecutive “information related to the first terminal” may come from different directions.

[1431] In one embodiment, the first target device includes one of the following: a second communication device; a second communication device.

[1432] In one implementation, the second timer may be locally configured or received from a third communication device.

[1433] In one embodiment, optionally, the second behavior further includes:

[1434] When the third information is sent to at least one of the third communication devices, the fifth information is sent to the third communication device together;

[1435] or

[1436] When sending the second information to the first communication device, the first information is also sent to the first communication device;

[1437] or

[1438] When the second information is sent to the fourth communication device, information indicating the end of the first terminal is also sent to the fourth communication device.

[1439] In one embodiment, the first terminal is a terminal related to the first object or the first terminal is the first terminal related to the first object;

[1440] or

[1441] The operation on the first terminal ends, including: the operation on the first terminal of the first object ends;

[1442] or

[1443] Ending the interaction with the first terminal includes: ending the interaction with the first terminal of the first object;

[1444] or

[1445] Requesting to end the operation on the first terminal includes: requesting to end the operation on the first terminal related to the first object;

[1446] or

[1447] Requesting to end the interaction with the first terminal includes: requesting to end the interaction of the first terminal related to the first object;

[1448] The first object includes at least one of the following: a first service, a first operation, and a first session.

[1449] In one implementation, the terminal related to the first object (eg, the first terminal) is, for example, the first terminal determined by the information of the first object used to indicate and / or filter terminals.

[1450] In one embodiment, when information related to a first terminal (such as information from the first terminal or information to the first terminal) carries a first identifier (such as an identifier of a first object), it can be determined that the first terminal is a terminal related to the first object (referred to as a first object-related terminal for short).

[1451] The terminal related to the first object may be simply referred to as the terminal of the first object.

[1452] The first terminal related to the first object may be simply referred to as the first terminal of the first object.

[1453] The first object includes one of the following: a first service, a first operation, a first session;

[1454] In one scenario, there may be multiple first terminals associated with the first object, and operations on different first terminals associated with the first object, or interactions with different first terminals associated with the first object, are terminated separately.

[1455] In another scenario, a terminal can be a terminal associated with at least one first object. Operations on the same terminal by different first objects, or interactions with the same terminal by different first objects, are terminated independently. Therefore, the termination of an operation associated with first object A on a terminal does not affect operations associated with first object B on the terminal.

[1456] Therefore, the operation related to the first object A with one terminal is completed, and the operation of the first object B with the terminal is not affected.

[1457] It is easy to understand that the termination of the first terminal refers to the termination of an operation on a terminal related to a first object, or the termination of an interaction between a first object and a terminal.

[1458] The first object includes one of the following: a first service, a first operation, a first session;

[1459] The first terminal associated with the first object may be referred to as the first terminal of the first object. In one embodiment, the information sent by the first terminal of the first object includes a first identifier (e.g., an identifier of the first object). For example, if the response from the first terminal includes the first identifier, it indicates that the first terminal is the first terminal of the first object.

[1460] The first terminal may be the first terminal of one or more first objects. Different first objects are terminated separately.

[1461] For example, the first identifier of the first object A is A, and the first identifier of the first object B is B. If the response of the first terminal contains the first identifier A but does not contain the first identifier B, then the first communication device can determine that the first terminal of the first object A is found, or determine that the first terminal of the first object B is not found.

[1462] The first terminal is a first terminal related to the first object. For example, the first terminal is a first terminal determined according to information in the first object for indicating or filtering the first terminal.

[1463] In one embodiment, the information used to indicate or filter the first terminal includes at least one of the following:

[1464] One or more identifiers for identifying a single first terminal;

[1465] One or more identifiers for identifying the first terminal group;

[1466] Used to filter the information of the first terminal.

[1467] In one embodiment, the information used to screen the first terminals is different from or does not include at least one of the following: an identifier of the first terminal (e.g., an identifier of a single first terminal, i.e., an identifier used to identify a single first terminal) and an identifier of the first terminal group. For example, if the information used to screen the first terminals includes AAA, a match is considered only if the first terminal also includes AAA.

[1468] In one implementation, only first terminals that match the information used to indicate or filter the first terminals need to respond.

[1469] In one implementation, when the number of first terminals is small, an identifier of a single first terminal is used as information for indicating and / or screening the first terminals.

[1470] In another embodiment, when there are a large number of first terminals (such as 1,000), using the identifier of a single first terminal as information for indicating or filtering the first terminals is a relatively inefficient method. In this case, an identifier for identifying the first terminal group or the information for filtering the first terminals can be used.

[1471] In one implementation, optionally, the information sent by the second communication device to indicate the end of the first terminal includes at least one of the following:

[1472] The operation of the second communication device on the first terminal ends;

[1473] The interaction between the second communication device and the first terminal ends.

[1474] or

[1475] The information obtained from the first communication device and used to indicate the end of the first terminal includes at least one of the following:

[1476] The operation of the first communication device on the first terminal ends;

[1477] The interaction between the first communication device and the first terminal ends;

[1478] or,

[1479] The information obtained from the third communication device and used to indicate the end of the first terminal includes at least one of the following:

[1480] The operation of the third communication device on the first terminal ends;

[1481] The interaction between the third communication device and the first terminal ends;

[1482] or,

[1483] The information obtained from the fourth communication device and used to indicate the end of the first terminal includes at least one of the following:

[1484] The operation of the first terminal by the fourth communication device ends;

[1485] The interaction between the fourth communication device and the first terminal ends.

[1486] In one embodiment, optionally, the target association satisfies at least one of the following:

[1487] Terminal granularity association, terminal granularity context;

[1488] A target association is bound to at most one first terminal;

[1489] First object related target association;

[1490] a target association between the first communication device and the second communication device;

[1491] a target association between the first communication device and the third communication device;

[1492] A target association between the first communication device, the second communication device, and the third communication device.

[1493] In one embodiment, the association of the terminal granularity satisfies at least one of the following:

[1494] A target association can only correspond to zero or one first terminal;

[1495] A target association is bound to at most one first terminal.

[1496] The context of the terminal granularity satisfies at least one of the following:

[1497] A target context can only correspond to zero or one terminal;

[1498] A target context is bound to at most one terminal.

[1499] In one implementation, the first session is a session, association, or process corresponding to the first operation.

[1500] The target association related to the first object is shown in FIG6B below. The first object corresponds to at least one target association, and different target associations can be bound to different first terminals. After the first terminal ends, the binding with the target association can be released.

[1501] In one embodiment, optionally, the target identifier satisfies at least one of the following:
