Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] figure 1 is a schematic flow chart of a network address translation port resource management method according to an embodiment of the present invention, as shown in figure 1 As shown, the NAT port resource management method of the present invention specifically includes the following steps:

[0029] Step 1. The user needs to send TCP data or UDP data.

[0030] Step 2. Search the NAT entry corresponding to the data packet in the existing NAT entry table. If the corresponding NAT entry is found, execute step 3; otherwise, execute step 4.

[0031] Step 3, use the network address and network port number in the NAT entry information to replace the private address and private port number i...

Abstract

The invention discloses a method, and particularly relates to a method for managing network address translation port resources. The method comprises the steps that every time a data package is sent, the aging time of a network address translation port NAT entry corresponding to the data package is updated to be an initial ageing time T0, the initial ageing time T0 of a control link ranges from 30 minutes to 2 hours, and the initial ageing time T0 of a data link ranges from 3 minutes to 30 minutes; according to the data link, when the current usage rate of the NAT entry is not less than a preset threshold value, the remaining ageing time of the NAT entry is shortened; when the ageing time of the NAT entry is up, the NAT entry is released. Through the technical scheme, the NAT entry which is occupied and is not used can be fast released to solve the problem that a user cannot surf the Internet due to the fact that the NAT entry is used up.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a NAT (Network Address Translation, network address translation) entry (port) resource management method and system. Background technique [0002] With the development of wifi (wireless local area network) technology, HOTSPOT (wireless hot spot) has appeared in more and more places, which provides convenience for people to surf the Internet. However, due to the limitation of HOTSPOT's internal resources when converting network addresses and private addresses, when multiple end users use one HOTSPOT for large-traffic services at the same time, sometimes there will be insufficient NAT entry resources, resulting in users being unable to access the Internet. Therefore, it is necessary to develop a method for quickly releasing occupied but unused NAT entries, so as to solve the problem that users cannot access the Internet due to exhaustion of NAT entries. [0003] Current...
