While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and so that the scope of the present disclosure is completely conveyed to those skilled in the art.

[0028] The embodiment of the present disclosure provides a method for allocating an identity of a communication device, and the method for allocating an identity of a communication device is applied to a network device. FIG. 1 is a flowchart of a method for allocating an identity of a communication device according to an embodiment of the present disclosure. As shown in FIG. 1, the method for allocating an identity of a communication device can include the following steps.

[0029] S101, receiving an identity allocation request sent by a target communication device, the target communication device being a base station or a relay terminal; the relay terminal being a terminal configured for the base station to communicate with a tag device.

[0030] The method for allocating an identity of a communication device provided by the embodiment of the present disclosure is suitable for a scenario where a network device allocates an identity for a base station and a relay terminal.

[0031] In the embodiment of the present disclosure, the network device can be implemented in various forms. For example, the network device described in the present disclosure can include a core network, a network element, and the like, and can also be other devices. The specific embodiments of the present disclosure do not limit this.

[0032] In the embodiment of the present disclosure, the number of target communication devices can be one, and the number of target communication devices can also be multiple. The number of target communication devices can be determined according to actual conditions, and the specific embodiments of the present disclosure do not limit this.

[0033] In the embodiment of the present disclosure, the target communication device corresponds to the identity allocation request one-to-one, and specifically, one target communication device corresponds to one identity allocation request.

[0034] It should be noted that the identity allocation request is a request for applying for allocating an identity number (Identity document, ID) for the target communication device.

[0035] In the embodiment of the present disclosure, the target communication device can be a base station, and the target communication device can also be a terminal. The specific embodiments of the present disclosure do not limit this.

[0036] In the embodiments of the present disclosure, one relay terminal can be configured for the base station, or multiple relay terminals can be configured for the base station, and the number of relay terminals configured for the base station can be determined according to actual conditions, and the present disclosure does not limit this.

[0037] It should be noted that the relay terminal is deployed in an area far away from the base station, so as to inventory the tag devices in these areas.

[0038] S102, in the case that the first information of the target communication device supporting the passive IoT communication capability is carried in the identity identification allocation request, generating a target identity identification of the target communication device.

[0039] In the embodiments of the present disclosure, after the network device receives the identity identification allocation request sent by the target communication device, in the case that the first information of the target communication device supporting the passive IoT communication capability is carried in the identity identification allocation request, the network device generates a target identity identification of the target communication device.

[0040] In the embodiments of the present disclosure, the passive IoT communication capability can be the capability of supporting Ambient IoT inventory. The passive IoT can be Ambient IoT or Ambient power enabled IoT, and the specific type can be determined according to actual conditions, and the present disclosure does not limit this.

[0041] In the embodiments of the present disclosure, the process of generating the target identity identification of the target communication device by the network device includes: in the case that the target communication device is a relay terminal, obtaining the subscription information of the relay terminal; in the case that the subscription information identifies that the relay terminal has subscribed to the passive IoT communication service, determining that the verification of the first information is successful; and generating the target identity identification of the target communication device.

[0042] In the embodiments of the present disclosure, the network device generates the target identity identification of the target communication device in the case that it is determined that the verification of the first information is successful.

[0043] In the embodiments of the present disclosure, if the subscription information identifies that the relay terminal has subscribed to the passive IoT communication service, it is determined that the target communication device supports the passive IoT communication capability.

[0044] In the embodiments of the present disclosure, the subscription information means that the terminal and the operator network side sign a service supporting Ambient IoT inventory, and authorize the network side to inventory the tag devices by using the terminal.

[0045] In the embodiments of the present disclosure, the network device generates the target identity identification including one of the following:

[0046] The random number, the communication device identifier of the target communication device, and the network element information of the network device.

[0047] In the embodiments of the present disclosure, the network device can generate a random number and take the random number as the target identity identifier. The network device can also obtain the communication device identifier of the target communication device and take the communication device identifier as the target identity identifier. The network device can also obtain the network element information of the network device and take the network element information as the target identity identifier. The network device can also generate the target identity identifier in other manners, and the specific implementation manner can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0048] It should be noted that the network element information of the network device can be an authentication management function (AMF) ID. The communication device identifier of the target communication device includes a base station ID, a cell ID, and a relay terminal ID.

[0049] S103, sending the target identity identifier to the target communication device.

[0050] In the embodiments of the present disclosure, after the network device generates the target identity identifier of the target communication device, the network device sends the target identity identifier to the target communication device.

[0051] In the embodiments of the present disclosure, the process in which the network device receives the identity identifier allocation request sent by the target communication device includes: receiving a network connection request sent by the base station in the case that the target communication device is a base station; correspondingly, the target identity identifier includes a first identity identifier; the process in which the network device sends the target identity identifier to the target communication device includes: sending a network connection response corresponding to the network connection request to the base station, wherein the network connection response includes the first identity identifier allocated by the network device for the base station.

[0052] It should be noted that the identity identifier allocation request includes a network connection request.

[0053] In the embodiments of the present disclosure, the network connection request can be a request for the base station to establish an NG interface with the core network (network device), such as an NG SETUP REQUEST. Correspondingly, the network connection response can be an NG SETUP RESPONSE.

[0054] It should be noted that the network connection request carries the first information about the support of the passive Internet of Things communication capability of the base station.

[0055] In the embodiment of the present disclosure, a base station (gNodeB, gNB) sends "support Ambient IoT inventory" information to a core network (network device), which is used for the gNB to inform the core network that the gNB supports the Ambient IoT inventory function. This information can be carried in the "NG SETUP REQUEST". The gNB receives the communication device ID information (i.e., the first identity) sent by the core network to indicate the communication device ID (i.e., the first identity) used by the gNB. This information can be carried in the NG SETUP RESPONSE.

[0056] In the embodiment of the present disclosure, the process of receiving the identity allocation request sent by the target communication device by the network device includes: in the case that the target communication device is a relay terminal, receiving the registration request sent by the relay terminal from the base station, and correspondingly, the target identity includes a second identity; the process of sending the target identity to the target communication device includes: sending the second identity to the base station; and forwarding the second identity allocated by the network device to the relay terminal by the base station.

[0057] It should be noted that the identity allocation request includes the registration request.

[0058] In the embodiment of the present disclosure, since the relay terminal is a terminal configured by the base station and deployed in an area far away from the base station, which is used to inventory the tag devices in these areas, the relay terminal needs to interact with the network device through the base station.

[0059] In the embodiment of the present disclosure, the relay terminal first sends a registration request to the network device through the base station, and the registration request carries the first information of the relay terminal supporting the passive Internet of Things communication capability. After the network device receives the registration request, the first information is verified. In the case that the verification of the first information is successful, the second identity of the relay terminal is generated, and the second identity is forwarded to the relay terminal through the base station.

[0060] In the embodiment of the present disclosure, the relay terminal initiates a registration process (sends a registration request to the network device through the base station), and reports the relay terminal capability, which indicates the capability of the relay terminal supporting the Ambient IoT inventory. The network side (such as the core network, i.e., the network device) queries the registration information of the relay terminal to confirm whether the relay terminal subscribes to the Ambient IoT inventory service. For example, the base station receives the capability information of the relay terminal (i.e., the base station receives the first information), sends the capability information to the core network AMF (i.e., the network device), and queries the registration information (i.e., the subscription information) of the relay terminal in the UDM to confirm whether the relay terminal subscribes to the Ambient IoT inventory service. If the relay terminal has subscribed, the core network AMF allocates the second identity to the relay terminal.

[0061] It can be understood that the network device uniformly allocates the target identity (i.e., allocates the first identity and the second identity) for the relay terminal and the gNB, which can avoid the conflict between the second identity corresponding to the relay terminal and the first identity corresponding to the base station. The problem caused by the identity conflict between the relay terminal and the base station is that after the inventory tag device is inventoried, the network side needs to save the correspondence table of the base station or the relay terminal and the tag device, so that the next time only the specific tag device is inventoried, the network side only needs to send the inventory message to the specific base station or relay terminal, and there is no need to inventory again. If the identity of the relay terminal and the base station conflicts, the communication device corresponding to the tag device cannot be found.

[0062] In the embodiment of the present disclosure, after the network device sends the target identity to the target communication device, in the case that the target communication device is a base station, the network device sends an instruction for inventorying the tag device to the base station, so that the base station sends a first inventory instruction to the tag device; in the case that the base station receives a first response information of the tag device inventorying successfully, the network device acquires the first identity of the base station and the tag identity of the tag device from the first response information; according to the first identity and the tag identity, the network device establishes a first communication relationship between the base station and the tag device; and according to the first communication relationship, the network device instructs the base station to inventory the tag device next time.

[0063] In the embodiment of the present disclosure, the first inventory information is also the first inventory instruction, which can be query (Q). Wherein, the meaning of inventory is equivalent to paging, inventory, and inventory.

[0064] It should be noted that the number of the first inventory instruction is one.

[0065] In the embodiment of the present disclosure, the first response information can be the ID information of the RN16 and / or the tag device, or the first response information can be other information. The specific first response information can be determined according to the actual situation, and the embodiment of the present disclosure does not limit this.

[0066] It should be noted that the first response information can be the information configured in the tag device, or the information transmitted to the tag device by other devices, or the information obtained by the tag device through other ways. The specific way for the tag device to obtain the first response information can be determined according to the actual situation, and the embodiment of the present disclosure does not limit this.

[0067] In the embodiment of the present disclosure, the first response information further includes the first identity of the base station.

[0068] In the embodiment of the present disclosure, after the network device establishes the first communication relationship between the base station and the tag device according to the first identity and the tag identity, the base station can be instructed to inventory the tag device next time according to the first communication relationship.

[0069] For example, if the base station does not inventory the tag device according to the first communication relationship next time, the range of the gNB base station sending the inventory instruction can be expanded.

[0070] In the embodiment of the present disclosure, the manner in which the base station sends the first inventory instruction to the tag device can be determined according to actual conditions, and the embodiment of the present disclosure does not limit this.

[0071] In the embodiment of the present disclosure, after the network device sends the target identity to the target communication device, if the target communication device is a relay terminal, the base station sends an instruction to inventory the tag device to the relay terminal, so that the relay terminal sends a second inventory instruction to the tag device; if the relay terminal successfully inventories the tag device and the base station receives the second response information of the relay terminal, the second identity of the relay terminal, the first identity of the base station, and the tag identity of the tag device are obtained from the second response information; a second communication relationship between the base station, the relay terminal, and the tag device is established according to the second identity, the first identity, and the tag identity; and the relay terminal is instructed to inventory the tag device next time according to the second communication relationship.

[0072] In the embodiment of the present disclosure, the second response information can be the ID information of the RN16 and / or the tag device, or other information. The specific second response information can be determined according to actual conditions, and the embodiment of the present disclosure does not limit this.

[0073] It should be noted that the second response information can be information configured in the tag device, information transmitted to the tag device by other devices, or information obtained by the tag device through other manners. The specific manner in which the tag device obtains the second response information can be determined according to actual conditions, and the embodiment of the present disclosure does not limit this.

[0074] In the embodiment of the present disclosure, the second response information further includes the first identity of the base station and the second identity of the relay terminal.

[0075] In the embodiment of the present disclosure, after the network device establishes the second communication relationship between the base station, the relay terminal, and the tag device according to the second identity, the first identity, and the tag identity, the relay terminal can be instructed to inventory the tag device next time according to the second communication relationship.

[0076] For example, if the relay terminal does not inventory the tag device according to the second communication relationship at the next inventory, the range of the relay terminal sending the inventory instruction is expanded again.

[0077] In the embodiments of the present disclosure, the manner in which the relay terminal sends the second inventory instruction to the tag device can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0078] In the embodiments of the present disclosure, in the case where the network device receives the second response information transmitted by the base station in the case where the relay terminal successfully inventories the tag device, before the network device acquires the second identity of the relay terminal, the first identity of the base station and the tag identity of the tag device from the second response information, in the case where the tag device receives the first inventory instruction of the base station, and adjusts the inventory flag bit of the tag device to the inventory flag, and the adjustment duration of the inventory flag state is greater than or equal to the preset duration, and receives the second inventory instruction, the network device receives the second response information transmitted by the base station.

[0079] In the embodiments of the present disclosure, the inventory flag of the tag device can be a character flag, an image flag, or other forms of flags, and the specific inventory flag can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0080] In the embodiments of the present disclosure, in the case where the tag device receives the first inventory instruction transmitted by the base station, the tag device adjusts the inventory flag bit of the tag device to the inventory flag; the tag device sends the first response information of the successful inventory to the base station; in the case where the tag device receives the second inventory instruction transmitted by the relay terminal again, and the inventory flag bit is the inventory flag, the tag device prohibits responding to the second inventory instruction. Or after the tag device sends the first response information of the successful inventory to the base station, in the case where the tag device receives the third inventory instruction transmitted by the base station or other communication devices again, and the inventory flag bit is the inventory flag, the tag device prohibits responding to the third inventory instruction.

[0081] The second inventory instruction and the third inventory instruction are inventory instructions received after the first inventory instruction; and the other communication device is a communication device other than the base station or the relay terminal.

[0082] It should be noted that the number of second inventory instructions can be one, and the number of second inventory instructions can also be multiple, and the specific number of second inventory instructions can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0083] It should be noted that the number of third inventory instructions can be one, and the number of third inventory instructions can also be multiple, and the specific number of third inventory instructions can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0084] In the embodiments of the present disclosure, the tag device is prohibited from responding to the second inventory instruction if the tag device receives the second inventory instruction transmitted by the relay terminal again within a first time period after receiving the first inventory instruction, and the inventory flag bit is the inventoried flag.

[0085] In the embodiments of the present disclosure, the tag device adjusts the inventory flag bit of the tag device from the inventoried flag to the un-inventoried flag bit after a first time period after receiving the first inventory instruction.

[0086] In the embodiments of the present disclosure, the process of adjusting the inventory flag bit of the tag device to the inventoried flag includes: flipping the inventory flag bit of the tag device to obtain the inventoried flag; or setting the inventory flag bit of the tag device to obtain the inventoried flag.

[0087] In the embodiments of the present disclosure, the tag device can flip the flag information on the inventory flag bit to obtain the inventoried flag. For example, the flag information on the inventory flag bit of the tag device can be F when the tag device has not been inventoried, and the flag information on the inventory flag bit of the tag device is flipped to obtain -F, i.e., the inventoried flag, after the tag device is successfully inventoried.

[0088] In the embodiments of the present disclosure, the tag device can set the flag information on the inventory flag bit to obtain the inventoried flag. For example, the flag information on the inventory flag bit of the tag device can be 0 when the tag device has not been inventoried, and the flag information on the inventory flag bit of the tag device is set to obtain 1, i.e., the inventoried flag, after the tag device is successfully inventoried.

[0089] It can be understood that the inventory flag bit of the tag device is adjusted by flipping or setting, so that the tag device is prohibited from responding to the inventory instruction of the other communication device according to the inventoried flag, the tag device is prevented from being inventoried repeatedly by the target communication device and the other communication device, and the consumption of communication resources is reduced.

[0090] In the embodiments of the present disclosure, after the tag device adjusts the inventory flag bit of the tag device to the inventoried flag after receiving the first inventory information transmitted by the target communication device, the tag device adjusts the inventory flag bit of the tag device from the inventoried flag to the un-inventoried flag bit after a first time period after receiving the first inventory information.

[0091] The duration of the first time period is the preset duration.

[0092] In the embodiments of the present disclosure, the first time period can be determined by hardware of the tag device, can be a time period configured in the tag device, can be a time period sent to the tag device by a network side, or can be a time period obtained by the tag device in other manners. The manner in which the tag device obtains the first time period can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0093] For example, the duration of the first time period can be 2 minutes, the first time period can also be 1 minute, and the first time period can also be other time periods. The duration of the first time period can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0094] For example, in the case of flipping the inventory flag of the tag device to obtain the inventory flag, the manner of adjusting the inventory flag of the tag device from the inventory flag to the non-inventory flag can be flipping the inventory flag of the tag device to obtain the non-inventory flag. For example, if the flag information of the inventory flag is -F, the inventory flag of the tag device is flipped to obtain the non-inventory flag F on the non-inventory flag.

[0095] For example, in the case of setting the inventory flag of the tag device to obtain the inventory flag, the manner of adjusting the inventory flag of the tag device from the inventory flag to the non-inventory flag can be de-setting the inventory flag of the tag device to obtain the non-inventory flag. For example, if the flag information of the inventory flag is 1, the inventory flag of the tag device is de-set to obtain the non-inventory flag 0 on the non-inventory flag.

[0096] It can be understood that the tag device adjusts the inventory flag of the tag device from the inventory flag to the non-inventory flag after a period of time, that is, the tag device can respond to the inventory instruction transmitted by the target communication device or other communication devices after the period of time, so that the tag device can also communicate with other communication devices or the target communication device in the case that the target communication device does not communicate with the tag device, thereby reducing the consumption of communication resources.

[0097] In the embodiments of the present disclosure, the tag device inventoried by the base station will not respond to the inventory from the relay terminal again within a period of time (the first time period), and the tag device inventoried by the relay terminal will not respond to the inventory from the base station again within a period of time, so that the same tag device is avoided from being inventoried repeatedly by the base station and the relay terminal.

[0098] In the embodiments of the present disclosure, the gNB base station or the relay terminal sends the inventory information (first inventory instruction) to the tag device, and the inventory information instructs the tag device to flip or set the flag bit after completing the inventory. After receiving the inventory information, the tag device sends the RN16 and / or the tag device ID information to the base station or the relay terminal. After the tag device reports the tag device ID to the network device, the tag device flips or sets the flag bit. For example, the flag bit F is flipped to -F. Or 0 is set to 1. The above-mentioned flipping or setting can have a time limit (first time period), and after exceeding a certain time limit, the tag device will restore the original flag bit. The tag device that is flipped or set will not respond to the inventory message again after receiving the inventory message.

[0099] For example, the time length of the first time period is 1 minute, the un-inventory flag is F, and the first response information is the ID information of the tag device. When the tag device receives the first inventory information sent by the target communication device, the tag device adjusts the flag information F on the inventory flag bit of the tag device to the inventory flag (i.e., flips the inventory flag bit of the tag device to obtain the flag bit -F on the inventory flag bit), and sends the ID information of the tag device to the target communication device. Within 1 minute from receiving the first inventory information, the tag device is prohibited from responding to the inventory instruction again if the tag device receives the inventory instruction transmitted by the target communication device or other communication devices and the inventory flag bit is the inventory flag. After 1 minute from receiving the first inventory information, the inventory flag bit of the tag device is adjusted from the inventory flag to the un-inventory flag bit (i.e., -F is flipped to F).

[0100] For example, the time length of the first time period is 2 minutes, the un-inventory flag is 0, and the first response information is RN16. When the tag device receives the first inventory information sent by the target communication device, the tag device adjusts the flag information 0 on the inventory flag bit of the tag device to the inventory flag (i.e., sets the inventory flag bit of the tag device to obtain the flag bit 1 on the inventory flag bit), and sends the RN16 to the target communication device. Within 2 minutes from receiving the first inventory information, the tag device is prohibited from responding to the inventory instruction again if the tag device receives the inventory instruction transmitted by the target communication device or other communication devices and the inventory flag bit is the inventory flag. After 2 minutes from receiving the first inventory information, the inventory flag bit of the tag device is adjusted from the inventory flag to the un-inventory flag bit (i.e., 1 is reset to 0).

[0101] In the embodiments of the present disclosure, for the tag device to be inventoried, the core network (network device) finds the identity of the tag device (or gNB base station ID (i.e., the first identity), or relay terminal ID (i.e., the second identity)), determines the identity (gNB base station ID or relay terminal ID) that needs to be executed for inventory. The core network sends an inventory message (i.e., an instruction to inventory the tag device) to the target communication device (or gNB base station or relay terminal) according to the identity (gNB base station ID or relay terminal ID), and the message carries the tag identity of the tag device. The tag identity can be the ID of the tag device, or the mask, identification number, etc. of the tag device. The specific terminal tag ID can be determined according to actual conditions, and the embodiments of the present disclosure do not limit this.

[0102] For example, the relay terminal inventories the tag device, and the relay terminal reports its own communication device ID (second identity) and the identity of the tag device (i.e., the tag identity) to the network side device (base station or core network). The first network side device (such as a base station) inventories the tag device, and the first network side device (base station) reports its own communication device ID (first identity) and the identity of the tag device (i.e., the tag identity) to the second network side device (such as a core network mobility management node). Then, the network side device (such as the core network) saves the correspondence between the tag device and the terminal and the gNB base station. Next time the core network wants to inventory the tag device, it only needs to send an inventory message to the corresponding gNB base station or relay terminal according to the correspondence, so that the tag device can be inventoried with high probability. If the tag device cannot be inventoried, the range of gNB base stations or relay terminals sending the inventory message is expanded.

[0103] As shown in FIG. 2, the network device (core network) receives a network connection request sent by the base station, the network connection request carrying first information that the base station supports passive Internet of Things communication capability, generates a first identity of the base station, and sends a network connection response corresponding to the network connection request to the base station, the network connection response including the first identity. The network device (core network) receives a registration request sent by the relay terminal from the base station, the registration request carrying first information that the relay terminal supports passive Internet of Things communication capability, obtains subscription information of the relay terminal, and determines that the first information is verified successfully in a case where the subscription information indicates that the relay terminal has subscribed to a passive Internet of Things communication service. Then, a second identity of the relay terminal is generated, and the second identity is sent to the relay terminal through the base station. The network device (core network) sends an instruction for inventorying a tag device to the base station, so that the base station sends a first inventory instruction to the tag device. In a case where a first response information indicating that the base station successfully inventories the tag device is received, a first identity of the base station and a tag identity of the tag device are obtained from the first response information. A first communication relationship between the base station and the tag device is established according to the first identity and the tag identity. The base station is instructed to inventory the tag device next time according to the first communication relationship. The network device (core network) sends an instruction for inventorying a tag device to the relay terminal through the base station, so that the relay terminal sends a second inventory instruction to the tag device. In a case where a second response information indicating that the relay terminal successfully inventories the tag device is received, a second identity of the relay terminal, a first identity of the base station, and a tag identity of the tag device are obtained from the second response information. A second communication relationship among the base station, the relay terminal, and the tag device is established according to the second identity, the first identity, and the tag identity. The relay terminal is instructed to inventory the tag device next time according to the second communication relationship.

[0104] It can be understood that the network device generates a target identity of a target communication device in a case where the network device receives an identity allocation request sent by the target communication device and determines that the identity allocation request carries first information that the target communication device supports passive Internet of Things communication capability. The target communication device includes a base station and a relay terminal, and the relay terminal is a terminal configured for the base station to communicate with a tag device. That is, the network device allocates identities to the base station and the relay terminal respectively, so that the identities of the relay terminal and the base station are not the same, and the network device does not instruct the relay terminal and the base station to inventory the same tag device because the relay terminal and the base station have the same identity. This avoids the process of repeatedly inventorying a tag device by a target communication device and other communication devices, thereby reducing the consumption of communication resources.
