Fig. 7 is a flowchart in an optional another application scenario of the address obtaining method provided by the embodiment of the present disclosure, and fig. 7 illustrates a flow of obtaining an IPv6 address. The address acquisition method shown in fig. 7 includes the steps of:
indoor communication equipment sends DHCPv6Solicit message to outdoor communication equipment; requesting a DHCPv6 server to distribute an IPv6 address and network configuration parameters through a DHCPv6Solicit message;
after receiving the DHCPv6Solicit message, the outdoor communication equipment is connected through an air interface, and sends the received DHCPv6Solicit message to a network server;
the network server replies a DHCPv6 advertisement message to the outdoor communication equipment according to the received DHCPv6Solicit so as to inform the CPE that the address and the network configuration parameters can be distributed to the CPE through the DHCPv6 advertisement message;
the outdoor communication equipment receives the DHCPv6 advertisement message and forwards the received DHCPv6 advertisement message to the indoor communication equipment;
the indoor communication equipment acquires server parameters in the DHCPv6 advertisement message, sends a DHCPv6 Request multicast message to the outdoor communication equipment, and sends the DHCPv6 Request multicast message to the server through the outdoor communication equipment, wherein the message carries the DUID of the DHCPv6 server.
After receiving the DHCPv6 Request multicast message, the outdoor communication equipment sends the received DHCPv6 Request multicast message to a network server;
the network server replies a DHCPv6 Reply message to the outdoor communication equipment according to the received DHCPv6 Request multicast message; to confirm the assignment of addresses and network configuration parameters to the client for use;
after receiving the DHCPv6 Reply message, the outdoor communication equipment sends the DHCPv6 Reply message to the indoor communication equipment;
the indoor communication equipment acquires the IPv6 address information according to the received DHCPv6 Reply message.
Thus, the indoor communication device can transmit and receive data using the acquired address information. In the disclosed embodiment, the outdoor communication device provides air interface data transmission capability, and only transmits and receives data packets without performing unpacking and packaging processing.
The common home gateway can provide network service for the access device, and the connection mode is that the access device is directly connected with the home gateway. The home gateway acquires the IP address from the network server through the air interface signaling, and provides data transmission service for the access equipment.
Compared with the common home gateway mode for acquiring the IP address, according to the technical scheme provided by the implementation of the disclosure, the outdoor communication equipment (outdoor CPE) can acquire the IP address through air interface signaling and provide the acquired IP address for the indoor communication equipment to use, and meanwhile, the method can be configured to dynamically acquire the address from the network, namely: the outdoor communication equipment can acquire the IPv4 address from the network server in a DHCP mode, and the outdoor communication equipment can acquire the IPv6 address from the network server in a DHCPv6 mode.
Meanwhile, the outdoor communication device 102 serves as an outdoor CPE, an Indoor Device (IDU)101 of a user may be connected to the outdoor communication device 102, and the outdoor communication device 102 may operate in two modes, that is, the outdoor communication device 102 acquires an IPv4 address or/IPv 6 address from the network server 103 through air interface signaling, and then transmits data for the indoor communication device 101 using the acquired address (IPv4 address or/IPv 6 address). The outdoor communication device 102 supports the transparent transmission mode, when the indoor communication device 101 sends a DHCP request (i.e., a DHCP Discover packet) in a DHCP manner or sends a DHCPv6 request (i.e., a DHCPv6Solicit message) in a DHCPv6 manner, and acquires an address from the outdoor communication device 102, the outdoor communication device 102 also sends the DHCP request or the DHCPv6 request to the network server 103, and when the network server 103 responds to the DHCP request or the DHCPv6 request and sends back a DHCP response (i.e., a DHCP Ack message) or a DHCPv6 response (i.e., a DHCPv6 Reply message), the outdoor communication device 102 transmits a response message to the indoor communication device 101, and the outdoor communication device 102 only provides a data transmission path.
The technical scheme of the address acquisition method provided by the embodiment of the disclosure is a new method for accessing an indoor unit (IDU) to a network under the condition of expanding the capacity and improving the performance of a wireless network. Outdoor communication equipment (ODU) provides air interface data transmission capability, and only transmits and receives data packets without unpacking and packaging processing.

The technical scheme provided by the embodiment of the disclosure can better adapt to the application scenes of continuous development of the technology and network capacity expansion.
In the technical solution provided in the embodiment of the present disclosure, the address can be obtained in two ways: the first method is that outdoor communication equipment (outdoor CPE) acquires an IP address through air interface signaling; the second method is to dynamically acquire the address from the network server, namely, the IPv4 address is acquired from the IPv4 server by a DHCP mode or the IPv6 address is acquired from the IPv6 server by a DHCPv6 mode.
In order to increase coverage and increase capacity, a network base station adopts a bridge link backhaul capacity expansion mode, and base station equipment is newly added in an original coverage area. In this scenario, under the network architecture of the tandem bridging, the network base station may allocate an IP address to the wireless terminal in a dynamic address allocation manner, so that the address may be dynamically acquired through an air interface according to the technical solution provided by the embodiment of the present disclosure.
In addition, outdoor communication equipment (outdoor CPE) is connected with indoor communication equipment, the indoor communication equipment has a plurality of connecting links, the outdoor communication equipment works in a transparent transmission mode, and address allocation requests of the indoor communication equipment are transmitted to a network server through good wireless communication performance, so that various application services of the indoor communication equipment can be supported.
