Problems solved by technology

[0014] For the H(e)NB using NAT, for the massive use of H(e)NB and the extensiveness and versatility of its application, currently, there is no solution for the confirmation of the IP address of the H(e)NB using NAT , if there is no correct IP address, accurate information transmission cannot be performed, and the connection establishment and multimedia transmission of H(e)NB using NAT cannot be satisfied.

Embodiment Construction

[0071] Figure 4 It is a flow chart of the method for confirming the IP address of the network equipment of the present invention, such as Figure 4 shown, including:

[0072] Step 400: The core network obtains the public IP address of the private network and the NAT port information of each network device in the private network.

[0073] The private network includes one or more network devices, such as H(e)NB, helper node (HN, Helper Node), SeGW and so on.

[0074] In this step, the core network can obtain the public IP address of the private network and the NAT port information of each network device in the private network by requesting the HN of the private network. The HN can be located in the private network or in the SeGW.

[0075] The CN may, but is not limited to, send a command to obtain the public IP address of the private network and the NAT port information of the network device through an initial session protocol (SIP, Session Initiation Protocol), HTTP, or the...

Abstract

The invention provides an IP address confirmation method and a system of a network device, and the method comprises the steps of utilizing a core network for obtaining a public Internet protocol (IP) address of a private network and network address translation (NAT) port information of all network devices in the private network, obtaining a private IP address of the required network device according to the obtained NAT port information of the network devices and notifying the public IP address of the private network and the private IP address of the network device to the network device. The method ensures that the network device adopts the accurate IP address for carrying out accurate information transformation, thereby meeting the requirement of using the NAT network device for carrying out connection establishment and multimedia transformation.

Description

technical field [0001] The invention relates to a wireless cellular communication system, in particular to a method and system for confirming an IP address of a network device. Background technique [0002] A home base station (HNB, Home Node-B) is used to provide 3G wireless coverage for third-generation mobile communication system (3G) mobile terminals in the home, and the HNB is connected to existing residential broadband services. The HNB has the function of a standard Node B (that is, an element of the 3G macro radio access network) and the radio resource management function of a standard Radio Network Controller (RNC, Radio Network Controller). [0003] figure 1 It is a schematic diagram of the existing system structure including HNB, such as figure 1 As shown, wherein, the interface between the user equipment of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) and the HNB is backhauled and compatible in the Universal Terrestrial Radi...
