step 301, the terminal device sends a service message to the base station.
Correspondingly, the base station receives the service message sent by the terminal equipment.
In the implementation process, the terminal device in the embodiment of the application may be various intelligent home devices with information processing capability, for example, the terminal device may be a television, a refrigerator, a washing machine, etc. The terminal device can access the base station based on the relevant protocol and communicate data with the base station, in which case the terminal device can send the service message to the base station directly based on the relevant protocol after generating the service message.
Further, the smart home control device may be a control device such as a voice assistant and a mobile phone, which can control functions of the smart home device, and the terminal device generates a service message and then sends the service message to the base station.
In some embodiments, as described above, the terminal device is an intelligent home terminal device, and the service message sent by the intelligent home terminal device is carried in an unlicensed spectrum.
In other embodiments, the terminal device may be another device different from the smart home terminal device, where the service packet sent by the device is carried in the licensed spectrum or the unlicensed spectrum.
Step 302, the base station determines the spectrum type of the bearer service packet, if the spectrum type is unlicensed spectrum, step 303 is executed, otherwise step 304 is executed.
In some embodiments, the spectrum types include licensed spectrum and unlicensed spectrum.
The licensed spectrum refers to a frequency band licensed to a wireless communication service operator or a user through a related organization, for example, a frequency band used in a communication system such as a global system for mobile communications (Global System for Mobile Communications, GSM), code division multiple access (Code Division Multiple Access, CDMA), long term evolution (Long Term Evolution, LTE), or New Radio (NR) is the licensed spectrum.
The unlicensed spectrum refers to a spectrum which is recognized by a national radio administration in a designated area and does not require application of authorization to a radio spectrum management unit, a radio transmitting device transmits on the unlicensed spectrum, the transmission power required to meet the requirements of the radio management unit, and the device work under a specified interference avoidance coordination mechanism, such as a 3GPP 5G NR-U access mechanism and a Wi-Fi access mechanism.
In some embodiments, if the terminal device is an intelligent home device, the terminal device uses an unlicensed spectrum to send a service packet to the base station, and the base station determines that the spectrum type carrying the service packet is the unlicensed spectrum.
In other embodiments, if the terminal device is another device different from the smart home device, the terminal device uses the licensed spectrum to send the service message to the base station, and the base station determines that the spectrum type carrying the service message is the licensed spectrum.
In step 303, the base station sends the service packet to the edge UPF under the condition that the service packet is carried in the unlicensed spectrum.
The edge UPF is used for forwarding the service message to the private cloud server through a private cloud gateway interface connected with the edge UPF under the condition that the service message carries the LADN identifier.
The LADN represents a local area network, which is a function of the 5G network, and allows a local operator or an enterprise to provide data services in a limited geographical area, if the service packet carries the LADN identifier, the local operator is characterized as establishing a dedicated smart home network (i.e. a private cloud network) for the smart home device, so as to provide a specific service suitable for the requirements of the smart home device, and the service packet needs to be routed to a private cloud server in the smart home network, so as to provide high-speed data transmission service for the smart home device.
In step 304, the base station sends the service packet to the center UPF under the condition that the service packet is carried in the licensed spectrum.
In some embodiments, the central UPF further determines whether the service packet carries the LADN identifier, and if so, forwards the service packet to an edge UPF, so that the edge UPF forwards the service packet to a private cloud server through a private cloud gateway interface.
In some embodiments, other terminal devices different from the smart home device use the licensed spectrum to communicate with the base station, and the generated service message may also need to be processed by the private cloud server, if the service message sent by the other terminal device carries the LADN identifier, the local operator is characterized to also establish a private cloud network for the terminal device, so as to provide a specific service suitable for the requirement of the terminal device, and the service message needs to be routed to the private cloud server corresponding to the terminal device, so as to provide a high-speed data transmission service for the terminal device.
It can be understood that in the embodiment of the present application, the service packet may be split based on the type of the spectrum carried by the service packet, where the type of the spectrum can be identified at the physical layer of the base station, and the service packet does not need to be sent to the central UPF far away from the base station side, and the service packet is split by the central UPF. If the service message is carried in the unlicensed spectrum, the service message can be directly sent to the private cloud interface gateway interface through the edge UPE, and the private cloud gateway interface forwards the service message to the private cloud server, so that the routing path of the service message of the intelligent home equipment is as follows: compared with the prior art, the number of nodes on the routing path is reduced, the routing mode is simple, the transmission rate of service messages is improved, and the communication delay is reduced.
The embodiment of the application provides another communication method, which specifically describes the interaction flow among the modules when the service message is routed.
Fig. 4 is a schematic implementation flow chart of the present embodiment, and as shown in fig. 4, the communication method of the present embodiment includes the following steps 401 to 406:
in step 401, the terminal device sends a service packet to the base station.
The terminal equipment can be intelligent home equipment or other terminal equipment different from the intelligent home equipment, and the terminal equipment generates a service message based on service requirements.
If the terminal equipment is intelligent home equipment, the frequency spectrum borne by the service message is unlicensed frequency spectrum, and if the terminal equipment is other equipment different from the intelligent home equipment, the frequency spectrum borne by the service message is licensed frequency spectrum or unlicensed frequency spectrum.
If the terminal equipment is the intelligent home equipment, the intelligent home equipment sends the service message to the base station as described above.
Correspondingly, the base station receives the service message sent by the terminal equipment.
Step 402, the base station determines whether the spectrum type of the bearer service packet is unlicensed spectrum, if so, step 403 is executed, otherwise, step 407 is executed.
Step 403, forwarding the service message to the edge UPF.
Accordingly, the edge UPF receives the service message.
In step 404, the edge UPF determines whether the service packet carries a LADN identifier, if yes, step 405 is executed, otherwise step 406 is executed.
And step 405, the edge UPF sends the service message to a private cloud server through a private cloud gateway interface.
In step 406, the edge UPF sends the service packet to the public cloud server through the public cloud gateway interface.
Specifically, the edge UPF sends the service message to the center UPF, and the center UPF sends the service message to the public cloud server through the public cloud gateway interface.
In step 407, the base station sends the service packet to the center UPF.
In step 408, the central UPF determines whether the service packet carries a LADN identifier, if so, step 409 is executed, otherwise, step 410 is executed.
Step 409, the central UPF sends the service packet to the private cloud server through the private cloud gateway interface.
Specifically, the center UPF sends the service message to the edge UPF, and the edge UPF sends the service message to the private cloud server through the private cloud gateway interface.
In step 410, the central UPF sends the service message to the public cloud server through the public cloud gateway interface.
In this embodiment, after receiving a service packet, a base station may first split the service packet at the base station side based on the spectrum type carried by the service packet, and in the case that the service packet carrying type is an unlicensed spectrum, route the service packet carrying the LADN identifier to the private cloud server through the edge UPF, so that for the service packet that needs to be routed to the private cloud server, the number of nodes on the routing path is reduced, which is beneficial to improving the data transmission rate of the service packet and reducing the communication delay.
It can be understood that before sending the service message to the base station, if the terminal device is an intelligent home terminal device, the terminal device needs to send an intelligent home network configuration request to the base station first to request the base station to configure local network configuration information required by the terminal device to access the private cloud, including unlicensed spectrum information, and then the terminal device sends the service message to the base station based on the unlicensed spectrum information configured by the base station.

The intelligent home network configuration information comprises frequency point information of unlicensed spectrum configured by a base station for terminal equipment, an intelligent home network identifier (LADN) and/or an encryption key of the terminal equipment; the intelligent home network configuration information comprises frequency point information of an unlicensed spectrum configured by the base station for the terminal equipment and an intelligent home network identifier (LADN), and/or the intelligent home network configuration information comprises frequency point information of the unlicensed spectrum configured by the base station for the terminal equipment and an encryption key.
The intelligent home network identifier LADN is used for identifying that a server to which the terminal equipment is routed is a private cloud server corresponding to the terminal equipment, and the encryption key is used for encrypting a service message sent by the terminal equipment.
It can be understood that, for different smart home devices, the private cloud platform to which the smart home devices are connected may be different, and accordingly, unlicensed spectrum configured by the base station, and the LADN value may also be different, that is, unlicensed spectrum configuration information corresponding to different terminal devices is different. Therefore, for different intelligent home devices, unlicensed spectrum configuration information required by the intelligent home device to access the private cloud platform can be determined according to the address of each intelligent home device.
Step 505, the service management platform of the public cloud server sends the intelligent home network configuration information containing the unlicensed spectrum to the base station through the central UPF.
Correspondingly, the base station receives the intelligent home network configuration information.
And step 506, the base station sends the intelligent home network configuration information to the intelligent home control equipment.
In step 507, the smart home control device forwards the smart home network configuration information to the terminal device.
Further, the terminal device sends the service message based on the intelligent home network configuration information, specifically, see the following steps 508 to 511.
Step 508, the terminal performs sweep operation of the NR unlicensed spectrum based on the frequency point information of the NR access network in the configuration information of the smart home network, and reads the system broadcast message of the cell (i.e., the base station) serving the smart home network.
The system broadcast message includes the configuration information of the cell, the cell configuration information includes the timing, and based on the timing, an access request is initiated to the base station, so that the base station can be ensured to be successfully accessed into the cell.
Step 509, the base station determines, based on the system broadcast message, a timing of initiating an access request to the base station.
Step 510, the terminal initiates an access request to a cell serving the smart home network on an unlicensed spectrum indicated by the smart home network configuration information based on the timing.
In step 511, after the terminal device is successfully connected, i.e. the connection carried by the unlicensed spectrum is established with the base station serving the cell of the smart home network, the service message is sent to the base station on the unlicensed spectrum based on the timing, so that the base station routes the service message to the edge UPF.
In this embodiment, before sending a service packet to a base station, a terminal device sends intelligent home network configuration information to an intelligent home control device through a D2D interface based on an unlicensed spectrum, so as to request the intelligent home network configuration information to a public cloud server management platform, and after obtaining the intelligent home network configuration information, the terminal device may send the service packet directly to the base station based on the unlicensed spectrum indicated by the intelligent home network configuration information, so that the terminal device may implement the request of the intelligent home network configuration information and the sending of the service packet under the condition that only the unlicensed spectrum is supported, thereby reducing the requirements on the spectrum supported by the terminal wireless transmission module and reducing the cost of the terminal.
