Problems solved by technology
However, using the STUN protocol to complete the process of obtaining the network address requires the application program to support the STUN Client function, and to process through the STUN Server, that is, to be supported by the STUN Server at the same time, so for some low-end products, the product cost is increased.

Embodiment Construction
[0017] The embodiment of the present invention provides a method and a terminal for obtaining a network address, which can obtain the network address simply and conveniently, avoid the high cost problem caused by obtaining the network address through the STUN technology, and meet people's demand for low cost.
[0018] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] see figure 1 A flow chart of a method for obtaining a network address according to an embodiment of the present invention is shown, the method includes:
[0020] Step S101: Sending an IKE configuration payload request, the IKE configuration payload request carrying preset network address acquisition instruction information;
[0021] Step S102: receiving an IKE configuration payload request response, the IKE configuration payload request response carrying network address information;
[0022] Step S103: Analyzing the IKE config...

The embodiment of the invention discloses a method for acquiring network address comprising: sending Internet key exchanging protocol configuration load request, the IKE configuration load request carrying preset indication information for acquiring network address; receiving response to IKE configuration load request, the IKE configuration load request response carrying network address information; resolving the IKE configuration load request response, acquiring network address information. Accordingly, the embodiment of the invention also discloses a terminal. IKE configuration request carrying indication information for acquiring network address is transmitted to target terminal through simply extending IKEv2 protocol. Network address can be conveniently acquired by interacting with target terminal about IKE configuration load, thereby avoiding high cost of acquiring network address through STUN technology and satisfying demand of people for low cost.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and a terminal for acquiring a network address. Background technique [0002] In the field of communication technology, Internet Protocol (IP, Internet Protocol) addresses, commonly referred to as network addresses, are limited. Network Address Translation (NAT, Network Address Translation) technology is one of the methods to solve the shortage of IP addresses. NAT The technology converts IP addresses so that multiple hosts in the same LAN use fewer public network addresses to access external resources. However, NAT technology converts IP addresses on the NAT server. This transparent address conversion The processing prevents each host in the NAT LAN from directly knowing the actual public network address used when the local end sends to the destination end. However, in current NAT network applications, upper-layer applications often need to use the actual IP address for busin...
