In the related art, when a plurality of personal internet of things devices access to a 5GS (5G system) through the same personal internet of things gateway, it is difficult for a 5G core network to identify and distinguish different personal internet of things devices. For example, in the internet of things, the watch can access the 5G network through the mobile phone, but the 5G network cannot identify the watch, and only the mobile phone which establishes connection for the internet of things device can be known.
In addition, as the 5G core network is difficult to identify and distinguish different personal Internet of things devices, the flow of the different personal Internet of things devices is difficult to charge respectively. For example, the traffic used by the mobile phone and the watch is counted in the usage amount of the mobile phone user.
The communication method can realize the distinction of the core network to different Internet of things devices accessed through the same personal networking gateway.
Fig. 1 illustrates a flow chart of a communication method according to some embodiments of the present disclosure.
As shown in fig. 1, the communication method is applied to the personal networking gateway, and includes steps S11-S13.
In step S11, after establishing connection with the personal internet of things device, the personal internet of things gateway allocates an IP address to the personal internet of things device.
For example, the personal internet of things gateway uniformly distributes an IP address for the personal internet of things device accessed to the gateway, and generates IP information including the IP address.
After the personal Internet of things equipment and the personal Internet of things gateway are connected, that is, before the personal Internet of things equipment needs to communicate, the IP address is allocated to the personal Internet of things equipment, occupation of the IP address by the free personal Internet of things equipment is avoided, and allocation of the IP address is more dynamic and flexible.
In some embodiments, assigning an IP address to a personal internet of things device includes: when the type of the protocol data unit session is IPv4, distributing a port range of a transmission control protocol or a port range of a user datagram protocol for the personal Internet of things equipment; or when the type of the protocol data unit session is IPv6, distributing the prefix of IPv6 for the personal Internet of things equipment.
For example, the personal internet of things gateway serves as an IP route, when the PDU session type is IPv4, an IPv4 address is allocated to the personal internet of things device, for example, a port range of TCP/UDP (Transmission Control Protocol/User Datagram Protocol ), and when the PDU session type is IPv6, an IPv6 prefix is allocated to the personal internet of things device. DN (Data Network) provides services to personal internet of things devices through IPv4 or IPv 6.
In step S12, the personal internet of things gateway initiates an establishment procedure of a protocol data unit session used by the personal internet of things device.
For example, the personal internet of things gateway initiates a procedure of establishing a PDU (Protocol Data Unit ) session between the personal internet of things device and the core network, that is, establishing a data path between the personal internet of things device and the DN, so as to realize communication of the personal internet of things device.
In some embodiments, initiating the establishment procedure of a protocol data unit session for use by a personal internet of things device comprises: in a process of establishing a protocol data unit session used by the personal internet of things device, a message forwarding service is provided between the personal internet of things device and a core network.
For example, after the personal internet of things device initiates a procedure of establishing a PDU session, the personal internet of things gateway forwards a message between the personal internet of things device and the core network to assist the personal internet of things device in successfully establishing the PDU session with the core network.
In some embodiments, the communication method further comprises: a set-up procedure for a protocol data unit session used by a personal internet of things gateway is initiated.
For example, the personal internet of things gateway initiates a PDU session establishment procedure, establishing a PDU session for use by itself.
In some embodiments, initiating the establishment procedure of a protocol data unit session for use by a personal internet of things device comprises: a procedure is initiated to modify a protocol data unit session used by the personal internet of things gateway to a protocol data unit session used by the personal internet of things device.
For example, the personal internet of things gateway initiates a modification procedure to modify a PDU session that would otherwise only be established and used by the personal internet of things gateway into a PDU session that may also be used by the personal internet of things device.
In some embodiments, initiating the establishment procedure of a protocol data unit session for use by a personal internet of things device comprises: a process is initiated to establish a new protocol data unit session for use by the personal internet of things device.
For example, instead of having the personal internet of things device use the original personal internet of things gateway to establish and use the PDU session, the personal internet of things gateway can initiate an establishment procedure to newly establish the PDU session for the personal internet of things device.
In step S13, the personal internet of things gateway sends a report of the personal internet of things device and an identifier of a protocol data unit session used by the personal internet of things device to the core network, wherein the report of the personal internet of things device includes an IP address of the personal internet of things device, so as to provide a communication service for the personal internet of things device according to the report of the personal internet of things device and the identifier of the protocol data unit session used by the personal internet of things device.
For example, the personal internet of things gateway sends a report (pin report) of the personal internet of things device and an identification of a PDU session used by the personal internet of things device corresponding to the report to the core network, and can identify to which personal internet of things device the traffic packet is for when communicating. The core network can correctly identify different personal Internet of things devices accessed to the same personal Internet of things gateway and PDU session used by the personal Internet of things devices, and provides communication service for the different personal Internet of things devices.
According to the method and the device, the IP address is allocated to the personal Internet of things equipment, the PDU session used by the personal Internet of things equipment is established, the IP address of the personal Internet of things equipment and the identification of the PDU session used by the personal Internet of things equipment are sent to the core network, so that the core network can identify and distinguish different personal Internet of things equipment accessed to the unified personal Internet of things gateway according to the IP address of the personal Internet of things equipment and the identification of the PDU session used by the personal Internet of things equipment, and the operator can manage and control the personal Internet of things equipment.
In some embodiments, sending a report of the personal networking device and an identification of a protocol data unit session used by the personal networking device to the core network includes: and sending the report of the personal Internet of things equipment and the identification of the protocol data unit session used by the personal Internet of things equipment to the session management functional entity through the access and mobile management functional entity by the non-access layer message.
For example, the personal internet of things gateway sends the report of the personal internet of things device to the SMF (SessionManagement function ) entity of the core network through the AMF (Access and Mobility Management Function ) entity of the core network by means of an N1 SM NAS (non-access-stratum) message.
In some embodiments, the report of the personal internet of things device further includes an identification of the personal internet of things device.
For example, an identifier is allocated to the personal internet of things device by the personal internet of things gateway or the application server, and the personal internet of things gateway binds the pin ID (identifier of the personal internet of things device) with the IP address allocated to the personal internet of things device, and sends the report to the core network as a report of the personal internet of things device.
In some embodiments, the communication method further comprises: an identification of a personal networking device is received from the personal networking device.
For example, in the case where the application server allocates an identifier to the personal internet of things device, the personal internet of things device sends the acquired identifier to the personal internet of things gateway.
In some embodiments, the communication method further comprises: performing access authentication of the personal Internet of things; acquiring parameters related to a gateway of the personal Internet of things; and sending parameters related to the personal Internet of things gateway to the personal Internet of things device.
For example, the personal internet of things gateway performs access authentication of the personal internet of things, and the personal internet of things authorizes and configures the personal internet of things gateway. And the personal internet of things gateway acquires personal internet of things parameters (PEGC info) related to the personal internet of things gateway during authentication and sends the personal internet of things parameters (PEGC info) to personal internet of things equipment, and the personal internet of things equipment is used for judging whether the personal internet of things gateway is connectable.
In some embodiments, the communication method further comprises: receiving quality of service information and quality of service rules related to the personal internet of things device from the personal internet of things device; and initiating a flow of binding the flow of the personal Internet of things equipment to the service quality flow of the personal Internet of things gateway according to the service quality information and the service quality rule related to the personal Internet of things equipment.
For example, if the personal internet of things supports QoS (Quality of Service ) control of the connection between the personal internet of things gateway and the personal internet of things device, the personal internet of things gateway may acquire QoS info (quality of service information), priority value, etc. and QoS Rules (quality of service Rules) for quality of service guarantee from the personal internet of things device.
If the personal internet of things gateway initiates a procedure of modifying the protocol data unit session used by the personal internet of things gateway to the protocol data unit session used by the personal internet of things device, the personal internet of things gateway initiates a procedure of binding the traffic of the personal internet of things device to the service quality flow of the original personal internet of things gateway according to the service quality information and the service quality rule in the modified procedure.
In some embodiments, the communication method further comprises: receiving quality of service information and quality of service rules related to the personal internet of things device from the personal internet of things device; and initiating a process of establishing a new service quality flow for the personal Internet of things equipment according to the service quality information and the service quality rule related to the personal Internet of things equipment.
For example, if the personal internet of things gateway initiates a process of establishing a new protocol data unit session for use by the personal internet of things device, then, correspondingly, in the process of newly establishing the PDU session, the personal internet of things gateway initiates a process of establishing a new quality of service flow for the personal internet of things device according to the quality of service information and the quality of service rules.
Fig. 2 shows a flow chart of a communication method according to further embodiments of the present disclosure.
As shown in fig. 2, the communication method is applied to the personal networking device, and includes steps S21 to S23.
In step S21, a connection is established with the personal internet of things gateway, so that the personal internet of things gateway allocates an IP address to the personal internet of things device.
For example, after accessing to the personal internet of things, the personal internet of things device is connected to the personal internet of things gateway through WiFi, bluetooth, and the like when communication is required. The personal networking gateway allocates an IP address for the personal Internet of things device accessed to the personal networking gateway.
In some embodiments, the communication method further comprises: performing access authentication of the personal Internet of things; an identification of the personal networking device is obtained.
For example, the personal internet of things device performs access authentication of the personal internet of things, and the personal internet of things device authorizes and configures the personal internet of things device. And the personal internet of things equipment acquires personal internet of things parameters related to the personal internet of things equipment, such as identification of the personal internet of things equipment, during authentication. The identification of the personal internet of things device is assigned to the personal internet of things device by the personal internet of things gateway or the application server.
In some embodiments, the communication method further comprises: receiving parameters related to the personal Internet of things gateway from the personal Internet of things gateway; and according to the parameters related to the personal Internet of things gateway, discovering the personal Internet of things gateway which is allowed to be connected nearby.
For example, the personal internet of things device determines whether the personal internet of things gateway is connectable according to parameters related to the personal internet of things gateway, and selects one of the connectable personal internet of things gateways to establish connection.
In step S22, in response to the personal internet of things gateway initiating a procedure for establishing a protocol data unit session for use by the personal internet of things device, a protocol data unit session for use by the personal internet of things device is established with the core network.
For example, in response to the personal internet of things gateway initiating a procedure to establish a PDU session between the personal internet of things device and the core network, the personal internet of things device and the core network together establish the PDU session used by the personal internet of things device to enable communication of the personal internet of things device.
In some embodiments, in response to the personal internet of things gateway initiating a flow to establish a protocol data unit session for use by the personal internet of things device, establishing the protocol data unit session for use by the personal internet of things device with the core network, comprising: and responding to the process that the personal Internet of things gateway initiates the modification of the protocol data unit session used by the personal Internet of things gateway into the protocol data unit session used by the personal Internet of things device, and modifying the protocol data unit session used by the personal Internet of things gateway into the protocol data unit session used by the personal Internet of things device with the core network.
For example, if the personal internet of things gateway initiates a procedure of modifying a protocol data unit session used by the personal internet of things gateway to a protocol data unit session used by the personal internet of things device, the personal internet of things device and the core network cooperate to modify the protocol data unit session used by the personal internet of things gateway to a protocol data unit session used by the personal internet of things device accordingly.
In some embodiments, in response to the personal internet of things gateway initiating a flow to establish a protocol data unit session for use by the personal internet of things device, establishing the protocol data unit session for use by the personal internet of things device with the core network, comprising: and in response to the personal internet of things gateway initiating a process of establishing a new protocol data unit session used by the personal internet of things device, establishing the new protocol data unit session used by the personal internet of things device with the core network.
For example, if the personal internet of things gateway initiates a procedure for establishing a new protocol data unit session for use by the personal internet of things device, the personal internet of things device and the core network together correspondingly establish the new protocol data unit session for use by the personal internet of things device.
In step S23, the IP address of the personal internet of things device and the identification of the protocol data unit session used by the personal internet of things device are used to access to the core network for communication via the personal internet of things gateway.
For example, the personal internet of things equipment communicates by utilizing the PINE IP address through the PDU session, so that the core network can correctly identify different personal internet of things equipment accessed to the same personal internet of things gateway and the PDU session used by the personal internet of things equipment, and communication services are provided for different personal internet of things equipment.
According to the method and the device, the personal internet of things gateway is used for distributing the IP address to the personal internet of things equipment and establishing the PDU session used by the personal internet of things equipment, so that the core network can identify different personal internet of things equipment accessed through the same personal internet of things gateway according to the IP address of the personal internet of things equipment and the identification of the PDU session used by the personal internet of things equipment.
In some embodiments, the communication method further comprises: and sending the service quality information and the service quality rule related to the personal Internet of things equipment to the personal Internet of things gateway.
For example, if the personal internet of things supports QoS (Quality of Service ) control of the connection between the personal internet of things gateway and the personal internet of things device, the personal internet of things device transmits QoS info (quality of service information) and QoS Rules (quality of service Rules) related to the personal internet of things device to the personal internet of things gateway for quality of service guarantee.
Fig. 3 illustrates a flow chart of a communication method according to some embodiments of the present disclosure.
As shown in fig. 3, the communication method is applied to the core network, and includes steps S31 to S23.
In step S31, the core network establishes a protocol data unit session used by the personal internet of things device in response to the personal internet of things gateway initiating a procedure for establishing the protocol data unit session used by the personal internet of things device.
