Checking method for IP address

Abstract

This invention discloses a method for checking IP address including: A. setting the check position parameter, storing the check position of last turn address of the system and setting the largest checked number of this turn B. determining the IP address position in the present check APN C. judging if the said IP address is idle, if so, the check position parameter is corrected to carry out step B or step D, D judging if the said IP address exists the context to carry out step E if so, or, setting the IP address idle E. adding I to the IP address number of this turn to judge if this turn number is smaller than the largest address number to carry out B if so, or to finish the check of this turn, increasing check efficiency and solving the problem of IP address resource hung-up effectively.

Description

technical field [0001] The invention relates to an address check technology of a wireless network system, in particular to a method for checking an IP address in a wireless data communication mobile gateway node. Background technique [0002] In a wireless data communication system, a mobile user terminal has one or more IP addresses, and these IP addresses may be static addresses, Remote Authentication Dial-In User Service (RADIUS, Remote Authentication Dial-In User Service) addresses or dynamic addresses. The static address refers to the fixed IP address assigned by the operator to each user, which is a one-time assigned address; the RADIUS address refers to the IP address assigned to the user by the authentication, authorization and accounting (AAA, Authentication, Authorization and Accounting) server ; The dynamic address refers to the IP address assigned to the user by the gateway GPRS support node (GGSN) when the user is activated. [0003] As shown in Figure 1, the G...

Problems solved by technology

Generally speaking, a full piece is 32 bits, so the last piece may be a fragment with less than 32 bits

[0017] Although this method can check the IP address, because the GGSN may configure multiple APNs, and the number of addresses configured by each APN is different, when performing address checking, the processing mechanism with the APN as the unit checks that the number of IP addresses is uneven ; Moreover, if there are many addresses configured under an APN, the number of IP addresses to be checked at one time will be relatively large, which will greatly affect system performance and have a great impact on normal business

At the same time, because a task takes up too much CPU processing time, it usually leads to system exceptions.
