With the rapid growth of the scale of mobile users and the continuous innovation of mobile applications, the traffic carried by the mobile network presents a situation of geometric progression growth, and the characteristic that more and more traffic is indoors appears, which puts higher demands on operators to enhance indoor coverage. Indoor network coverage in a mobile network is larger and larger, and the distribution of network points of indoor base stations is denser and denser.
With the arrival of the 5G era, the coverage of mobile signals is smaller and smaller, so that the number of 5G base stations is increased by ten times and hundred times compared with the number of 4G base stations, and because the 5G signals have the characteristics of large attenuation, short coverage distance and poor penetrating power, the proportion of 5G indoor substations in the 5G substations is also technically larger and larger, the indoor substations are more densely distributed, the distribution number is large, and the like.
A room distribution system in an existing mobile network includes three nodes, namely, a baseband Unit (BBU), a Radio HUB Unit (rHUB), and a Radio remote Unit (pRRU, Pico Radio RF Unit).
Referring to fig. 1, fig. 1 is an architecture diagram of a conventional wireless network system, in which a radio frequency remote unit pRRU is used for transceiving a wireless signal, receiving a signal of a Mobile Terminal (MT) and transmitting the signal to a radio frequency convergence unit rHUB, and meanwhile receiving a signal of the radio frequency convergence unit rHUB and transmitting the signal to a corresponding mobile terminal, and the radio frequency remote unit pRRU is connected to the radio frequency convergence unit rHUB in a star cascade manner.
The radio frequency convergence unit rHUB is used for receiving signals of the radio frequency devices pRRU, converging the signals and then sending the converged signals to the base band unit BBU, meanwhile distributing the signals of the base band unit BBU to the radio frequency devices pRRU, and the radio frequency convergence unit rHUB is connected with the base band unit BBU in a star-chain hybrid cascade mode.
The base band unit BBU is responsible for processing base band signals, is connected with a mobile network core network, and accesses the Internet through the mobile network core network, thereby forming a mesh-distributed wireless network system. The indoor subsystem in the existing wireless mobile network can only provide wireless access service.
Under densely distributed indoor substations, there are also a large number of fixed internet access devices with clear internet access requirements.
The application provides a method for accessing a fixed internet device to a wireless network and an indoor distribution system, which aim to solve the technical problems in the prior art.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The embodiment of the present application provides a method for accessing a fixed internet device to a wireless network system, which is applicable to a 4G (the 4th generation mobile communication technology, fourth generation mobile communication technology) or 5G (5th generation wireless systems, fifth generation mobile communication technology) wireless network environment, and is also applicable to a 6G (6th generation mobile networks) wireless network environment in anticipation. It should be noted that, since the number of remote units serving as mobile signal access points in the 5G indoor subsystem is much larger than that of remote units in the 4G indoor subsystem, the embodiment of the present invention has higher applicability in a 5G wireless network environment. It is understood that the context of the indoor subsystem and the mobile network Core network referred to in the following embodiments of the present application are 5G wireless network environments, i.e., 5G indoor subsystem and mobile network Core network 5GC (5G Core).
Referring to fig. 2, a method for accessing a fixed internet access device to a wireless network system according to an embodiment of the present application includes:
s101, adding a physical network interface in the indoor distribution system to enable the fixed internet access equipment to access the indoor distribution system through the added physical network interface and establish a data packet transparent transmission mechanism between the indoor distribution system and a mobile network core network.

The fixed internet device in the embodiment of the application refers to a device which can be connected with the internet only after being connected with a physical network interface through a network cable, such as a desktop computer, a server, a television and the like.
As shown in fig. 1, a communication link exists between the indoor distribution system and the mobile network core network, so that the mobile terminal accessing the indoor distribution system accesses the internet. In order to realize that the fixed internet access equipment is accessed into the wireless network system and is communicated with the internet, a data packet transparent transmission mechanism between the indoor distribution system and the mobile network core network is further established, the data packet transparent transmission mechanism is a mechanism that a forwarding node is only responsible for transmitting a data packet to a destination node and does not need to process the data packet. In addition, the transparent data packet transmission mechanism of the embodiment of the present application is independent of the existing mobile network system, and specifically, a new communication link is directly created between the indoor distribution system and the mobile network core network in the embodiment of the present application, and the communication link is dedicated for transmitting the data packet of the fixed internet access device, so that in the transmission process, the indoor distribution system is not affected to transmit the data packet uploaded by the mobile terminal to the mobile network core network in the existing mobile network system (through the original communication link) and to send the data packet transmitted by the mobile network core network to the mobile terminal.

The DHCP (dynamic Host Configuration protocol) dynamic Host Configuration protocol is a network protocol of a local area network, the DHCP protocol adopts a client/server model, and a dynamic allocation task of a Host address is driven by a network Host. When the DHCP server receives the information of applying address from the network host, it will send the information of address configuration to the network host to realize the dynamic configuration of the address information of the network host.
According to the 3GPP (3rd Generation Partnership Project) protocol, the Session Management Function (SMF) of the mobile network core network 5GC already has the DHCPv4 (server and client) and DHCPv6 (server and client) functions, so in the embodiment of the present application, the SMF is used as a DHCP server to provide a DHCP service for the fixed internet access device, and the fixed internet access device can connect to the internet according to the DHCP service.
The embodiment of the application makes full use of the characteristic that the nodes in the indoor distribution system are widely and densely distributed, and the physical network interface is additionally arranged in the nodes, so that the fixed internet access equipment can be conveniently accessed to the indoor distribution system through the physical network interface, and the data packet of the fixed internet equipment can be transmitted to the mobile network core network through establishing a data packet transmission mechanism between the indoor distribution system and the mobile network core network without influencing the data transmission of the original wireless network system, since the 3GPP protocol specifies that the core network of the mobile network needs to have the DHCP function, the core network of the mobile network is used as a DHCP server to provide the DHCP service for the fixed internet access device, so that the wireless network system can provide the wired broadband network service, meanwhile, the indoor subsystem and the mobile network core network not only transmit the data of the wireless terminal, but also transmit the data of the fixed internet access equipment, so that the utilization rate of the equipment and the circuit of the indoor subsystem and the mobile network core network is improved.
On the basis of the above embodiments, as an alternative embodiment, adding a physical network interface in the room distribution system includes: and a physical network interface is additionally arranged on the radio remote unit and/or the radio convergence unit.
It should be noted that, the existing remote radio unit and radio convergence unit are provided with physical network interfaces, but the interfaces are used for connecting the remote radio unit and the radio convergence unit, and in the embodiment of the present application, it is considered that, because the remote radio unit and the radio convergence unit are densely distributed, the number of the physical network interfaces is added to the remote radio unit and/or the radio convergence unit, and the broadband wired access requirement of the fixed internet access device in an indoor environment can be met.
Fig. 3 is an architecture diagram of a wireless network system according to an embodiment of the present invention, as shown in fig. 3, in the embodiment of the present invention, compared with an existing wireless network system, physical network interfaces are added to a radio frequency remote unit and a radio frequency convergence unit, so that a fixed internet access device can access an indoor distribution system through the added physical network interfaces, and a communication link (shown by a solid line in the figure) dedicated for data transmission of the fixed internet access device is newly created between the indoor distribution system and a mobile network core network in addition to an original communication link (shown by a solid line in the figure) for data transmission of a mobile terminal, after the fixed internet access device is accessed to the indoor distribution system, the fixed internet access device sends a DHCP request, and the radio frequency remote unit or the radio frequency convergence unit connected to the fixed internet access device receives DHCP and gradually transmits the DHCP to the mobile network core network along the communication link through a packet transparent transmission mechanism, and the mobile network core network provides DHCP service for the fixed internet access equipment.
On the basis of the above embodiments, as an optional embodiment, the DHCP request carries the MAC address of the fixed internet access device. The MAC Address (Media Access Control Address), also called a Media Access Control Address (MAC Control Address), is an Address for confirming the location of a network device. The embodiment of the application forwards the DHCP request to the core network of the mobile network through a packet transparent transmission mechanism, and then further includes:
and receiving a response message sent by the mobile network core network according to the MAC address, and sending the response message to the fixed internet access equipment, so that the fixed internet access equipment can know whether the DHCP service is provided or not according to the response message.
It should be noted that, after receiving the DHCP request forwarded by the indoor distribution system, the mobile network core network according to the embodiment of the present application further needs to determine whether to provide a DHCP service for the fixed internet access device according to an MAC address carried in the DHCP request, and send a determination result to the indoor distribution system in a response message manner, where the indoor distribution system transmits the response message to the fixed internet access device, so that the fixed internet access device knows whether to provide the DHCP service according to the response message.
Specifically, the indoor subsystem receives a response message sent by a mobile network core network according to an MAC address, and sends the response message to the fixed internet access device, including:
the indoor distribution system receives an agreement message sent by a mobile network core network through a data packet transparent transmission mechanism, and the agreement message carries DHCP service configuration information;
and the indoor distribution system forwards the agreement message to the fixed internet equipment so that the fixed internet equipment can access the internet according to the DHCP service configuration information.
It will be appreciated that verifying the identity of a device before it enters the network is an effective way to ensure network security. After receiving a DHCP request carrying an MAC address, the core network of the embodiment of the application performs identity authentication on the fixed internet access device according to the MAC address, and sends an agreement message, which is one of response messages and is also referred to as a DHCP ACK message, if the authentication passes. And the agreement message carries DHCP service configuration information, so that the fixed internet equipment can successfully access the internet service provided by the wireless network system according to the DHCP service configuration information.
Optionally, the DHCP service configuration information in the embodiment of the present application includes an IP address allocated to a port of the fixed internet access device, an address of a DNS server, a gateway, a broadcast address, default lease time, and the like.
It should be understood that, in the embodiment of the present application, when sending the agreement message to the indoor subsystem, the mobile network core network is transmitted through a packet transparent transmission mechanism. Meanwhile, when sending the agreement message, the indoor subsystem is also transmitted through a data packet transparent transmission mechanism, see fig. 4, and in fig. 4, the indoor subsystem includes remote radio units 101 to 104 and radio convergence units 201 to 202, where the remote radio units 101 and 102 are connected to the radio convergence unit 201, and the remote radio units 103 and 104 are connected to the radio convergence unit 202. Communication links for data transmission of the mobile terminal are represented by solid lines among the radio remote units 101 to 104, the radio convergence units 201 to 202, the baseband unit 30 and the mobile network core network 40, and communication links for data transmission of the dedicated and fixed internet access devices are represented by dotted lines.

On the basis of the above embodiments, as an optional embodiment, if the mobile network core network fails to authenticate according to the MAC address, a reject message is sent through a packet transparent transmission mechanism, where the reject message is another response message, which is also referred to as a DHCP NACK message. The indoor distribution system receives a rejection message sent by the mobile network core network through a data packet transparent transmission mechanism, and forwards the rejection message to the fixed internet access equipment, so that the fixed internet access equipment can know that the mobile network core network is rejected to access the network according to the rejection message.
It should be noted that the DHCP request, the agreement message, and the rejection message in the embodiment of the present application all conform to the preset format of the DHCP message. In general, a DHCP message includes the following fields:
the OP field indicates the type of the message, and when the OP field is 1, it indicates that the message is a client (i.e., fixed internet access device, the following same reference), and when the OP field is 2, it indicates that the message is a server (i.e., SMF, the following same reference) response message.

The internet protocol Multimedia Subsystem (IMS) is a new network architecture for providing voice and data services. IMS is an architecture designed by the wireless standards community 3GPP to deliver Internet Protocol (IP) multimedia services to end users. Some examples of IMS services include voice over IP (VoIP), video teleconferencing, gaming, and the like. When users are at home or at work, they typically receive non-IMS data services, such as internet access, voice over IP (VoIP), and other services, through a gateway and a modem connected to or integrated with the gateway. If a user wishes to access an IMS service, the user needs to have an IMS subscription to the service along with an IMS identity. Also, currently, IMS services can only be accessed by user equipment with IMS identity. non-IMS user devices cannot access IMS services.
The embodiment of the application further provides a method for enabling the fixed internet access device to access the IMS service. At present, communication operators (for example, china mobile, china unicom, etc.) can provide more complete IMS services, and the operators provide IMS services for devices connected to a mobile network core network by setting an IMS server, and it can be understood that the IMS server is used for providing IMS service content and registration functions.
Specifically, after the fixed internet access device accesses the internet according to the DHCP service configuration information, the embodiment of the present application further includes:
the indoor subsystem receives an IMS network access request sent by the fixed internet equipment, and forwards the IMS network access request to the mobile network core network through a data packet transparent transmission mechanism, so that the mobile network core network forwards the IMS network access request to the IMS server, and the IMS server provides IMS service for the fixed internet equipment.
After receiving an IMS network access request sent by the fixed network access equipment, the IMS server completes IMS registration and authentication on the fixed network access equipment, if the authentication passes, the fixed network access equipment becomes a registered IMS client in the wireless network system, namely the fixed network access equipment can resume IMS services such as IMS voice and video call with other IMS clients (which can be mobile terminals or other fixed network access equipment) in the wireless network system, namely the IMS server can directly carry out VoLTE/VoNR voice and video call services with the existing IMS clients in the wireless network system.
On the basis of the above embodiments, as an optional embodiment, the indoor distribution system can also control the on and off of the limited network interface, so as to control whether the fixed internet access device can be connected to the wireless network system, and meanwhile, the indoor distribution system can also monitor the network services of the limited network interface, including internet services and IMS services, and ensure the stability and safety of network communication.
