Method for processing dymatic IP address in radio access technology

Abstract

This invention relates to a method for processing dynamic IP addresses in a radio access technology including: when a client machine puts forward a request for distributing dynamic IP address by a broadcast, the NE of the radio access network captures, analyzes and transfers said DHCP message between said client machine and said DHCP server to distribute the dynamic address for the client machine, which can support the distribution / relet / release of the dynamic IP address against the property of the access network only, even the DHCP server is a foreign entity, it can release the related resource in the access network device to avoid the waste of access network resource and timely interrupts user services of access network devices, besides, MSS can communicate with DHCP server directly without adding network signaling.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for processing dynamic IP addresses in wireless access technology. Background technique [0002] With the vigorous development of Internet services and the wide application of wireless networks, more IP mobile user services need to be supported. For example, how does the access network device support the IP address application process of the mobile user, how does the access network device know the IP address assigned to the mobile user, how does the access network device know whether the IP address application / renewal is successful or not, so as to decide whether to apply / renew the IP address? Actions that the access network can take after lease renewal fails. [0003] Combined below as figure 1 The shown WiMAX DHCP (Dynamic Host Control Protocol; Dynamic Host Control Protocol) framework system is taken as an example to illustrate the technical solution of the prior art 1 rel...

AI Technical Summary

Problems solved by technology

[0034] In view of the problems existing in the above-mentioned prior art, the object of the present invention is to provide a method for processing dynamic IP addresses in the wireless access technology. Through the present invention, the need to address the characteristics of the access network in the prior art is solved. Make full use of existing Internet protocols to support the process of dynamic IP address allocation / renewal / release; solve the problem in the prior art that when the DHCP server is an external network entity, the corresponding resources in the access network equipment cannot be released in time, The problem of waste of access network resources, and the inability to stop the user service of access network equipment in time, resulting in the problem of wrong statistics of users using access network resources; through the present invention, it solves the problem that MSS and DHCP cannot be used in the prior art. The server communicates directly, which leads to the need to increase the network signaling problem
