Problems solved by technology

To sum up, accurate information transmission cannot be performed without the correct IP address. A reasonable IP address confirmation mechanism for H(e)NB is aimed at the extensive use of H(e)NB and its wide application and versatility. Need to be implemented to satisfy the connection establishment and multimedia transmission of H(e)NB using NAT

Embodiment 1

[0097] Step 501: CN sends a command to obtain the public IP address of the private network and port mapping information of network devices (including H(e)NB, etc.) in the private network to the HN (Helpr Node) of the private network.

[0098] The HN can be located in the private network or in the SeGW.

[0099] Step 502: After receiving the command, the HN fails to successfully obtain the public IP address of the private network or the port mapping information of the network devices in the private network from the SeGW of the private network to which it belongs. The port mapping information includes the unique NAT port number of each network device and the binding information of the corresponding local port number.

[0100] Step 503: The HN sends the reason why it failed to obtain the public IP address of the private network or the port mapping information of the network equipment located in the private network from the SeGW of the private network to which it belongs, and the ...

Embodiment 2

[0102] Step 601: CN sends a command to obtain the public IP address of the private network and port mapping information of network devices (including H(e)NB, etc.) in the private network to the HN (Helpr Node) of the private network.

[0103] The HN can be located in the private network or in the SeGW.

[0104] Step 602: After receiving the command, the HN successfully obtains the public IP address of the private network and the port mapping information of the network devices in the private network from the SeGW of the private network to which it belongs. The port mapping information includes the unique NAT port number of each network device and the binding information of the corresponding local port number.

[0105] Step 603: the HN sends the public IP address of the private network and the port mapping information of each network device to the CN.

[0106] Step 604: After the CN successfully receives the public IP address and port mapping information of the private network ...

[0111] Step 701: CN sends a command to obtain the public IP address of the private network and port mapping information of network devices (including H(e)NB, etc.) in the private network to the HN (Helpr Node) of the private network.

[0112] The HN can be located in the private network or in the SeGW.

[0113] Step 702: After the HN receives this command, it successfully obtains the public IP address of the private network and the port mapping information of each network device in the private network from the SeGW of the private network to which it belongs. The port mapping information includes the unique NAT port number of each network device and the binding information of the corresponding local port number.

[0114] Step 703: the HN sends the public IP address of the private network and the port mapping information of each network device to the CN.

[0115] Step 704: After the CN successfully receives the public IP address and port mapping information of the private netwo...

Abstract

The invention provides a system and a method for determining an IP address of network equipment using network address translation, which are applied to a system comprising a core network and a private network, wherein when the core network is to determine the IP address of the network equipment in the private network, the method comprises the following steps that: the core network sends an order for acquiring a public IP address of the private network and port mapping information of the network equipment to the private network, and the private network sends the public IP address of the private network and the port mapping information of each network equipment to the core network after receiving the order; the core network sends a message for acquiring a private IP address of one of the network equipment to the private network according to the acquired port mapping information of the network equipment, and the private network sends the to-be-acquired private IP address of the network equipment to the core network after receiving the message for acquiring the private IP address of the network equipment; and the core network sends a notification message containing the public IP address of the private network and the acquired private IP address of the network equipment to the private network.

Description

technical field [0001] The invention relates to a wireless cellular communication system, in particular to a system and method for confirming an IP address of a network device using NAT (Network Address Translation, Network Address Translation). Background technique [0002] HNB (Home Node-B, home base station) is used to provide 3G wireless coverage for 3G (third generation mobile communication system) mobile phones in the home, and is connected to existing residential broadband services. It includes the function of a standard Node B (an element of the 3G macro radio access network) and the radio resource management function of a standard RNC (Radio Network Controller, radio network controller). [0003] figure 1 The system structure of HNB is described. The interface between the 3GPP (3rd Generation Partnership Project, third-generation cooperative enterprise project) user equipment and the HNB is a backhaul and compatible air interface in the UTRAN (Universal Terrestria...
