Fig. 4 is a schematic flow chart of a service processing method according to an embodiment of the present application. The service processing method is applied to a service processing system consisting of the terminal, the gateway, the access network equipment and the core network equipment. The service processing method comprises the following steps: S401-S406.
S401, the gateway receives the initial service message.
Specifically, when service registration needs to be completed in the core network or service transmission needs to be performed to the core network, the terminal may send an initial service message for service registration or service transmission to the gateway. Accordingly, the gateway may receive an initial service message for service registration or service transmission from the terminal.
The initial service message is sent after the terminal encapsulates the original service message through a first protocol. The first protocol is a communication protocol for performing bluetooth communication between the terminal and the gateway.
Optionally, the gateway comprises a bluetooth gateway for communicating based on bluetooth wireless technology. The bluetooth gateway may be a bluetooth gateway that integrates both bluetooth wireless technology and 5G wireless communication technology.
Optionally, the terminal includes a bluetooth terminal for performing communication based on a bluetooth wireless technology.
As shown in fig. 5, protocols in a Bluetooth protocol stack (Bluetooth stack) corresponding to a Bluetooth terminal may be classified into a core protocol, a cable replacement protocol, a telephony transmission control protocol, and an optional protocol.
The core protocol is composed of Bluetooth special protocols established by Bluetooth special interest group (Bluetooth SIG), and includes a Baseband (Baseband) protocol, a Link Manager Protocol (LMP), a logical link control and adaptation protocol (L2 CAP), a Service Discovery Protocol (SDP), and a digital sound format (Audio).
The cable replacement protocol includes the serial line emulation protocol (RFCOMM), which provides services for upper layer protocols that use a serial line transport mechanism.
The telephony transport control protocol includes a Binary telephony control protocol (TCS-Binary, TCS Bin) and an AT command set (AT-commands).
The selected protocols include a point-to-point protocol (PPP), a User Datagram Protocol (UDP), a Transmission Control Protocol (TCP), an Internet Protocol (IP), an object exchange protocol (OBEX), an electronic business card exchange format (vCard), an electronic calendar and a schedule exchange format (vCal).
In this embodiment, when the terminal is a bluetooth terminal that performs communication based on a bluetooth wireless technology, a non-access stratum (NAS) protocol corresponding to NAS application and a protocol data unit (PDU Layer) protocol corresponding to PDU Session application are also configured in the selected protocol. The bluetooth terminal can select corresponding protocols according to the requirements of different applications.
For example, when the initial service message is a message for service registration, the initial service message is an initial NAS message obtained by encapsulating, by the first protocol, an original NAS message constructed by the NAS application. When the initial service message is a message for service transmission, the initial service message is an initial PDU Session message obtained by encapsulating an original PDU Session message constructed by the PDU Session application by the first protocol.
In addition to the above protocols, the bluetooth protocol stack also includes a Host Controller Interface (HCI) that provides a command interface for the baseband controller, the connection manager, the hardware status and control registers. In FIG. 5, HCI is located at the lower level of L2CAP, but HCI may also be located at the upper level of L2 CAP.
Alternatively, as shown in fig. 5, the first protocol may be one or more protocols on the bluetooth protocol stack, and is used to encapsulate the initial service message, so as to implement transmission of the initial service message between the terminal and the gateway.
Optionally, the terminal may encapsulate, through the first protocol, information such as device parameters of the terminal, and the original NAS message or the original PDU Session message to obtain the initial service message.
Optionally, the NAS message may be used to complete service registration of the terminal in the core network, so that the terminal obtains the IP address allocated by the core network. The PDU Session message may be used to complete service transmission between the terminal and the core network, and may include an IP address allocated by the core network for the terminal and service data to be transmitted.
Optionally, the communication mode between the gateway and the terminal may be transparent transmission.
In this way, the bluetooth terminal may construct an NAS message for service registration through the preconfigured NAS application, or may construct a PDU Session message for service transmission through the preconfigured PDU Session application, thereby implementing access to the 5GC based on the bluetooth radio technology, or performing bidirectional data exchange with the 5 GC.
S402, the gateway analyzes the initial service message through the first protocol, and encapsulates the analyzed initial service message through the second protocol to obtain the target service message.
Specifically, after receiving an initial service message for service registration or service transmission, the gateway may parse the initial service message through the first protocol, and encapsulate the parsed initial service message through the second protocol to obtain a target service message.
The second protocol is a communication protocol for communication between the gateway and the access network device.
Optionally, the second protocol may include UDP and IP, and may further include a plurality of underlying protocols supported by the physical layer, and the like.
Alternatively, the access network device may be an N3IWF for supporting NON-3GPP access 5 GC.
It should be noted that, after the terminal encapsulates information such as device parameters of the terminal and the original NAS message or the original PDU Session message to obtain the initial service message through the first protocol, the terminal may send the initial service message to the gateway. When the gateway analyzes the initial service message through the first protocol, the original NAS message or the original PDU Session message can be completely extracted, and information such as device parameters of the terminal can be acquired, and then the target service message can be obtained through encapsulation of the second protocol.
If the initial service message is a message for service registration (i.e. an initial NAS message), the gateway analyzes the initial NAS message through a first protocol, completely takes out the original NAS message constructed by NAS application, acquires information such as equipment parameters of a terminal and the like, and then obtains a target NAS message for service registration through second protocol encapsulation, thereby sending the target NAS message to the access network equipment.
If the initial service message is a message for service transmission (i.e. an initial PDU Session message), the gateway analyzes the initial service message through the first protocol, completely extracts the original PDU Session message constructed by the PDU Session application, acquires the information such as the equipment parameters of the terminal, and then obtains a target PDU Session message for service transmission through the second protocol encapsulation, thereby sending the target PDU Session message to the access network equipment.
Optionally, the data type of the target service message may be a UDP packet.
Thus, in the embodiment of the present application, the initial service message may be converted into the target service message that can be received by the N3IWF in the 5GC through the gateway, so as to implement transmission of the NAS message or the PDU Session message to the 5 GC.
S403, the gateway acquires the terminal identification of the terminal.
Specifically, after the communication connection is established between the terminal and the gateway, the gateway may assign a unique terminal identifier to the terminal and store the unique terminal identifier in the storage module in advance. When the analyzed initial service message is encapsulated through the second protocol, the gateway may obtain the terminal identifier of the terminal from the storage module.
Optionally, the terminal identifier may be generated by the gateway based on the device parameter of the terminal, and may also be a Universal Unique Identifier (UUID), or another identifier for uniquely representing the terminal identity.
S404, the gateway adds the terminal identification to the target service message and sends the target service message to the access network equipment.
Specifically, after acquiring the terminal identifier of the terminal, the gateway may add the terminal identifier to the target service message, and send the target service message for service registration or service transmission to the access network device. Correspondingly, the access network equipment receives a target service message which is sent by the gateway and used for service registration or service transmission.
Alternatively, as shown in fig. 6, when the data type of the target service message is a UDP packet, the gateway may add the terminal identifier of the terminal to the private header of the target service message.
Optionally, the communication mode between the gateway and the access network device may be transparent transmission.
S405, the access network equipment determines a target communication interface corresponding to the target service message based on the target service message.
Specifically, after receiving the target service message sent by the gateway, the access network device may determine, based on the target service message, a target communication interface corresponding to the target service message.
Optionally, the access network device may determine, according to the target service message, a terminal identifier corresponding to the target service message, and map the terminal identifier corresponding to the target service message to an identifier of an idle communication interface, so that the communication interface corresponding to the identifier is used as the target communication interface corresponding to the target service message.
Optionally, when the target service message is a target NAS message for registration, the target NAS message may be a control plane message.
When the target service message is a target PDU Session message for service transmission, the target PDU Session message may be a user plane message.
Optionally, a category identifier for indicating that the target service message is a control plane message or a user plane message may be added to the message header of the target service message. After receiving the target service message from the gateway, the access network device may determine whether the target service message is a target NAS message for registration or a target PDU Session message for service transmission, according to the category identifier in the message header of the target service message.
S406, the access network device sends the target service message to the core network device through the target communication interface.
Specifically, after determining a target communication interface corresponding to the target service message, the access network device may send the target service message to the core network device through the target communication interface.
It should be noted that, when the access network device sends the target NAS message through the N2 interface, the core network device may be an AMF network element, so as to complete service registration of the terminal in the core network.
When the access network device sends the target PDU Session message through the N3 interface, the core network device may be a UPF network element, so as to implement service transmission between the terminal and the core network.
For example, as shown in fig. 7, after the Bluetooth terminal constructs an original NAS message based on the NAS protocol through the NAS application, the original NAS message may be obtained by encapsulating the original NAS message with a first protocol (i.e., one or more protocols on the Bluetooth stack), and then the original NAS message is sent to the Bluetooth gateway.
After receiving the initial NAS message from the terminal, the Bluetooth gateway may parse the initial NAS message through a first protocol (i.e., one protocol or multiple protocols on the Bluetooth stack), determine information such as the initial NAS message and device parameters of the terminal, encapsulate the parsed initial NAS message through a second protocol (i.e., UDP and IP, and multiple underlying protocols represented by L1 and L2) to obtain a target NAS message, add the terminal identifier to the target service message, and then send the target NAS message to an access network device (N3IWF) through a NWu interface, so as to complete forwarding (Relay) of the initial NAS message.
After receiving the target NAS message from the bluetooth gateway, the N3IWF may parse the target NAS message through the second protocol (i.e., UDP and IP, and a plurality of underlying protocols denoted by L1 and L2) to obtain an original NAS message, and after determining a target N2 interface corresponding to the target NAS message, may encapsulate the original NAS message through an N2 protocol stack (N2 stack), and send the N2stack encapsulated NAS message to the AMF network element through a target N2 interface, so as to complete forwarding (Relay) of the original NAS message.
Then, the AMF network element may parse the N2stack encapsulated NAS message received from the N3IWF through the N2stack to obtain an original NAS message, and parse the original NAS message according to the NAS protocol to complete the service registration of the terminal in the core network.
For example, as shown in fig. 8, after the Bluetooth terminal applies the original PDU Session message constructed based on the PDU Layer protocol through the PDU Session, the original PDU Session message may be obtained by encapsulating the original PDU Session message through the first protocol (i.e., one or more protocols on the Bluetooth stack), and then the original PDU Session message is sent to the Bluetooth gateway.
After receiving the initial PDU Session message from the terminal, the Bluetooth gateway may parse the initial PDU Session message through a first protocol (i.e., one protocol or multiple protocols on the Bluetooth stack), determine information such as the initial PDU Session message and device parameters of the terminal, encapsulate the parsed initial PDU Session message through a second protocol (i.e., UDP and IP, and multiple underlying protocols represented by L1 and L2) to obtain a target PDU Session message, add a terminal identifier to the target service message, and then send the target PDU Session message to an access network device (N3IWF) through an NWu interface, so as to complete forwarding (Relay) of the initial NAS message.
After receiving the target PDU Session message from the bluetooth gateway, the N3IWF may parse the target PDU Session message through the second protocol (i.e., UDP and IP, and a plurality of underlying protocols represented by L1 and L2) to obtain an original PDU Session message, and after determining a target N3 interface corresponding to the target PDU Session message, may encapsulate the original PDU Session message through an N3 protocol stack (N3 stack), so as to send the N3stack encapsulated PDU Session message to the UPF network element through the target N3 interface, so as to complete forwarding (Relay) of the original NAS message.
Then, the UPF network element may analyze the received PDU Session message encapsulated by the N3stack from the N3IWF through the N3stack to obtain an original PDU Session message, and analyze the original PDU Session message according to the PDU Layer protocol to complete service transmission between the terminal and the core network.
In this way, in this embodiment of the present application, the terminal may send the target service message to the core network device through the access network device by the gateway, so that the core network device executes a service action in response to the target service message, to complete service registration of the terminal in the core network, or service transmission between the terminal and the core network.
In an implementation manner, with reference to fig. 4 and as shown in fig. 9, in S405, the method for determining, by an access network device, a target communication interface corresponding to a target service message based on the target service message specifically includes: S901-S902.
S901, the access network equipment analyzes the target service message to obtain a terminal identifier.
Specifically, after receiving a target service message for service registration or service transmission sent by the gateway, the access network device may parse the target service message to obtain the terminal identifier.
Optionally, the access network device may parse the private message header of the target service message to obtain the terminal identifier.
S902, the access network equipment determines the communication interface corresponding to the terminal identification as a target communication interface.
Specifically, after the terminal identifier is obtained, the access network device may determine the communication interface corresponding to the terminal identifier as the target communication interface.
For example, when the access network device determines that the target service message is a target NAS message for registration, it may determine a terminal identifier corresponding to the target NAS message according to the target NAS message, and map the terminal identifier corresponding to the target NAS message to a communication interface identifier of an idle N2 interface, so that the N2 interface corresponding to the communication interface identifier is used as a target communication interface corresponding to the target NAS message.
When the access network device determines that the target service message is a target PDU Session message for registration, it may determine a terminal identifier corresponding to the target PDU Session message according to the target PDU Session message, and map the terminal identifier corresponding to the target PDU Session message to a communication interface identifier of an idle N3 interface, so that the N3 interface corresponding to the communication interface identifier is used as a target communication interface corresponding to the target PDU Session message.
In this way, the gateway may allocate a terminal identifier to each of the plurality of terminals, and add the terminal identifier of each terminal to the target service message, so that the access network device determines a target communication interface corresponding to the terminal identifier of each terminal. When the core network is in communication connection with a plurality of terminals, the core network can realize the perception of the terminals through the corresponding relation between the target communication interface and the terminal identification.
In the embodiment of the application, after receiving an initial service message for service registration or service transmission, because the initial service message is sent after a terminal is encapsulated by a first protocol for communicating with a gateway, and a second protocol is a communication protocol for communicating between the gateway and an access network device, the gateway can analyze the initial service message by the first protocol, and can send a target service message to the access network device after the analyzed initial service message is encapsulated by the second protocol to obtain the target service message. Correspondingly, the access network device may receive the target service message sent by the gateway, and determine a target communication interface corresponding to the target service message based on the target service message, so as to send the target service message to the core network device through the target communication interface. In this way, in the embodiment of the present application, the terminal may send the initial service message to the core network device through the access network device by the gateway, so as to complete service registration or service transmission, thereby implementing that the terminal accesses the 5GC based on the bluetooth wireless technology.
