With the rapid growth of the scale of mobile users and the continuous innovation of mobile applications, the traffic carried by a 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 ratio in a mobile network is larger and larger, and network points of indoor base stations are distributed densely and densely.
With the advent of the 5G age, 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 that of 4G base stations, and as the 5G signals have the characteristics of large attenuation, short coverage distance, poor penetrating power, the specific gravity of 5G indoor branch stations in the 5G stations is also larger and larger technically, the indoor branch stations are distributed more densely, the distribution quantity is large, and the like.
The indoor subsystem in the existing mobile network comprises three nodes, namely a baseband Unit (BBU), a radio convergence Unit (rHUB, radio HUB) and a remote radio Unit (pRRU, pico Radio RF Unit).
Referring to fig. 1, fig. 1 is a schematic diagram of an existing wireless network system, a remote radio unit pRRU is used for receiving and transmitting wireless signals, receiving signals of a Mobile Terminal (MT) and transmitting the signals to a radio convergence unit rHUB, and simultaneously receiving signals of a radio convergence unit rHUB and transmitting the signals to a corresponding mobile terminal, and a remote radio unit pRRU is connected to the radio convergence unit rHUB in a star cascade manner.
The radio frequency aggregation unit rHUB is configured to receive and aggregate signals of the plurality of radio frequency devices pRRU, and send the aggregated signals to the baseband unit BBU, and meanwhile, distribute signals of the baseband unit BBU to each radio frequency device pRRU, where the radio frequency aggregation unit rHUB is connected to the baseband unit BBU in a manner of star link hybrid cascade.
The baseband unit BBU is responsible for processing baseband signals, is connected with the mobile network core network, and is accessed to the Internet through the mobile network core network, so that a netlike distributed wireless network system is formed. The existing indoor subsystem in the wireless mobile network can only provide wireless access service.
Under densely distributed indoor branch sites, a large number of fixed internet surfing devices exist at the same time, and the fixed internet surfing devices have clear network surfing requirements.
The application provides a method for accessing fixed internet equipment to a wireless network and a room division system, which aim to solve the technical problems in the prior art.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
The embodiment of the application provides a method for accessing a fixed internet device into a wireless network system, which is suitable for a wireless network environment of 4G (the 4th generation mobile communication technology, fourth generation mobile communication technology) or 5G (5 th generation wireless systems, fifth generation mobile communication technology), and is also suitable for a wireless network environment of 6G (6 th generation mobile networks). It should be noted that, because the remote radio unit serving as the mobile signal access point in the 5G indoor subsystem is far more than the remote radio unit in the 4G indoor subsystem, the embodiment of the application has higher practicability in the 5G wireless network environment. It is understood that the context of the indoor subsystem and the mobile network Core network in the subsequent embodiments of the present application are all 5G wireless network environments, namely, a 5G indoor subsystem and a mobile network Core network 5GC (5G Core).
Referring to fig. 2, a method for accessing a fixed internet device to a wireless network system according to an embodiment of the present application includes:
S101, a physical network interface is additionally arranged in the indoor subsystem, so that the fixed internet equipment is connected into the indoor subsystem through the additionally arranged physical network interface, and a data packet transparent transmission mechanism between the indoor subsystem and a mobile network core network is established.
The embodiment of the application provides a new access function in the indoor subsystem, namely, provides the access function for the fixed internet equipment by adding a physical network interface (Physical Network Interface) in a node of the indoor subsystem, so that the indoor subsystem can be connected with the mobile terminal in the mobile network through the existing wireless network interface and can also be connected with the fixed internet equipment through the physical network interface.
The physical network interfaces of embodiments of the present application include, but are not limited to, ethernet cable interfaces, fiber optic interfaces, and the like.
The fixed internet surfing 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 can be seen from fig. 1, a communication link exists between the indoor subsystem and the mobile network core network, so that the mobile terminal accessing the indoor subsystem accesses the internet. In order to realize that the fixed internet equipment accesses the wireless network system and is communicated with the Internet, the application further establishes a data packet transmission mechanism between the indoor subsystem and the mobile network core network, namely, a forwarding node is only responsible for transmitting the data packet to a destination node without a mechanism for processing the data packet. In addition, the data packet transparent transmission mechanism of the embodiment of the application is independent of the existing mobile network system, and specifically, the embodiment of the application directly creates a new communication link between the indoor subsystem and the mobile network core network, and the communication link is special for transmitting the data packet of the fixed internet access equipment, so that the data packet uploaded by the mobile terminal is not influenced by the indoor subsystem in the existing mobile network system (through the original communication link) to be transmitted to the mobile network core network and the data packet transmitted by the mobile network core network is transmitted to the mobile terminal in the transmission process.
S102, the room subsystem receives the DHCP request sent by the fixed Internet equipment, forwards the DHCP request to the mobile network core network through a data packet transmission mechanism, and the mobile network core network provides DHCP service for the fixed Internet equipment according to the DHCP request.
It should be appreciated that the fixed network device will send a DHCP request to the DHCP server to request access to network data, such as IP addresses, subnet masks, gateway addresses, DNS addresses, etc., when accessing the network.
DHCP (Dynamic Host Configuration Protocol) dynamic host configuration protocol is a network protocol of a local area network, DHCP protocol adopts a client/server model, and the dynamic allocation task of host addresses is driven by a network host. When the DHCP server receives the address information from the network host, the DHCP server sends relevant address configuration information and the like to the network host so as to realize dynamic configuration of the address information of the network host.
According to the 3GPP (3 rd Generation Partnership Project, third generation partnership project) protocol, the session management function (SMF, session Management Function) of the mobile network core network 5GC already has DHCPv4 (server and client) and DHCPv6 (server and client) functions, so that the embodiment of the present application uses the SMF as a DHCP server to provide DHCP services for a fixed internet device, and the fixed internet device can connect to the internet according to the DHCP services.
The embodiment of the application fully utilizes the characteristic that nodes in the indoor subsystem are widely and densely distributed, adds a physical network interface in the nodes, so that the fixed internet access equipment can be conveniently accessed into the indoor subsystem through the physical network interface, and can be transmitted to the mobile network core network through establishing a data packet transmission mechanism between the indoor subsystem and the mobile network core network, meanwhile, the data transmission of the original wireless network system is not influenced, and because the 3GPP protocol prescribes that the mobile network core network has a DHCP function, the mobile network core network is used as a DHCP server to provide DHCP service for the fixed internet access equipment, so that the wireless network system can provide wired broadband network service, and meanwhile, because the indoor subsystem and the mobile network core network not only transmit data of a wireless terminal, but also transmit data of the fixed internet access equipment, the method improves the utilization rate of equipment and lines of the indoor subsystem and the mobile network core network.
Based on the above embodiments, as an optional embodiment, adding a physical network interface in the indoor subsystem includes: and a physical network interface is additionally arranged on the remote radio unit and/or the radio convergence unit.
It should be noted that, physical network interfaces are provided on the existing remote radio units and the radio frequency convergence units, but the purpose of the interfaces is to connect the remote radio units and the radio frequency convergence units.
Fig. 3 is a schematic diagram of a wireless network system provided by the embodiment of the present application, as shown in fig. 3, compared with the existing wireless network system, in the embodiment of the present application, physical network interfaces are added on a remote radio unit and a radio convergence unit, so that a fixed internet device can access a room subsystem through the added physical network interfaces, a communication link (shown by a solid line in the figure) dedicated for data transmission of the fixed internet device is newly created between the room subsystem and a mobile network core network besides an original communication link (shown by a solid line in the figure) for data transmission of the mobile terminal, after the fixed internet device accesses the room subsystem, the fixed internet device sends a DHCP request, and a remote radio unit or a radio convergence unit connected with the fixed internet device receives the DHCP and gradually transmits the DHCP to the mobile network core network along the communication link through a packet transmission mechanism, so that the mobile network core network provides DHCP service for the fixed internet device.
On the basis of the above embodiments, as an alternative embodiment, the DHCP request carries the MAC address of the fixed internet device. The MAC Address (MEDIA ACCESS Control Address), referred to as a medium access Control Address, also referred to as a local area network Address (LAN ADDRESS), is an Address used to identify the location of the network device. The embodiment of the application forwards the DHCP request to the mobile network core network through a data packet transparent transmission mechanism, and then comprises the following steps:
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 equipment so that the fixed internet equipment can know whether the DHCP service is provided according to the response message.
It should be noted that, after receiving the DHCP request forwarded by the indoor subsystem, the mobile network core network of the embodiment of the present application further needs to determine whether to provide the DHCP service for the fixed internet device according to the MAC address carried in the DHCP request, and send the result of the determination to the indoor subsystem in a manner of a reply message, where the indoor subsystem transmits the reply message to the fixed internet device, so that the fixed internet device obtains whether to provide the DHCP service according to the reply message.
Specifically, the indoor subsystem receives a response message sent by a mobile network core network according to the MAC address, and sends the response message to the fixed internet surfing device, including:
The indoor subsystem receives an agreement message sent by a mobile network core network through a data packet transmission mechanism, wherein the agreement message carries DHCP service configuration information;
And the indoor subsystem forwards the agreement message to the fixed internet equipment so that the fixed internet equipment accesses 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 a MAC address, the core network in the embodiment of the present application performs identity authentication on the fixed internet device according to the MAC address, and if the authentication passes, sends an approval message, which is one of response messages, and is also called a DHCP ACK message. And the agreement message carries the DHCP service configuration information so that the fixed Internet surfing 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 device, an address of a DNS server, a gateway, a broadcast address, a default lease time, and so on.
It should be understood that, in the embodiment of the present application, the mobile network core network transmits the grant message to the indoor subsystem through a packet transparent transmission mechanism. Meanwhile, when the indoor subsystem sends the agreement message, the agreement message is transmitted through a data packet transmission mechanism, referring to fig. 4, the indoor subsystem in fig. 4 includes remote radio units 101-104 and radio convergence units 201-202, where the remote radio units 101 and 102 are connected with the radio convergence unit 201, and the remote radio units 103 and 104 are connected with the radio convergence unit 202. The communication links for data transmission of the mobile terminal are shown by solid lines among the remote radio units 101 to 104, the radio aggregation units 201 to 202, the baseband unit 30 and the mobile network core network 40, and the communication links for data transmission of the dedicated and fixed internet equipment are shown by dashed lines.
After receiving the grant message, the baseband unit 30 sends the grant message to the radio frequency convergence unit 201 through a communication link dedicated for transmitting data transmission of the fixed internet access device, the radio frequency convergence unit 201 sends the grant message to the remote radio unit 101 through a communication link dedicated for transmitting data packets of the fixed internet access device, the remote radio unit 101 sends the grant message to the fixed internet access device 50, the fixed internet access device 50 accesses the internet according to the received grant message, and after accessing the internet, the fixed internet access device can realize data interaction with other devices and websites in the internet through dedicated communication links among the remote radio unit 101, the radio frequency convergence unit 201, the baseband unit 30 and the mobile network core network 40.
Based on the above embodiments, as an alternative embodiment, if the mobile network core network fails to authenticate according to the MAC address, a reject message is sent through the packet transparent transmission mechanism, where the reject message is another response message, which is also called as DHCP NACK message. The indoor subsystem receives a refusing message sent by the mobile network core network through the data packet transparent transmission mechanism, and forwards the refusing message to the fixed internet equipment, so that the fixed internet equipment knows that the network access is refused according to the refusing message.
It should be noted that, in the embodiment of the present application, the DHCP request, the grant message, and the reject message 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, when the OP field is 1, it indicates that the message is a client (i.e., a fixed internet device, the same applies hereinafter) request message, and when the OP field is 2, it indicates that the message is a server (i.e., SMF, the same applies hereinafter) response message.

For MESSAGE TYPE fields, when the value of the field is 3, the message is a DHCP request, when the value is 5, the message is a DHCP ACK response packet, namely an agreeing message, and when the value is 6, the message is a DHCP NACK reject packet, namely a reject message.
The internet protocol multimedia subsystem (IMS, IP Multimedia Subsystem) is a new network architecture for providing voice and data services. IMS is an architecture designed by the wireless standards body 3GPP to transport 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 and an IMS identity. Furthermore, currently, IMS services are only accessible to user equipment having an IMS identity. non-IMS user devices cannot access IMS services.
The embodiment of the application further provides a method for enabling the fixed internet equipment to access the IMS service. Currently, communication operators (such as china mobile, china corporation, etc.) can provide relatively perfect IMS services, and the operators provide IMS services for devices connected to a mobile network core network by setting an IMS server for the mobile network core network to connect to, and it can be understood that the IMS server is used to provide IMS service content and registration functions.
