Embodiment Construction

[0164] A method for processing dynamic IP addresses in the wireless access technology of the present invention, the core of which is: when the client needs to renew the lease or release the allocated dynamic IP address, the client communicates with the wireless access The inter-network air interface management message reports the result of the Dynamic Host Control Protocol DHCP process to the wireless access network; the wireless access network performs corresponding processing on the assigned dynamic IP address according to the result of the DHCP process .

[0165] Combine below figure 2 and image 3 The first embodiment provided by the present invention is described.

[0166] Such as figure 2 As shown, it is the process of assigning an IP address to the MSS by transparently transmitting the broadcast message between the MSS and the DHCP server through the network elements of the wireless access network, which includes:

[0167] Step 11, the MSS (client) sends the DHCP ...

Abstract

The key ideal of the invention comprises: when the client machine need to be rehired or to release its allocated dynamical IP address, through the air interface management message between the client machine and the wireless access network, the result of DHCP procedure is reported to the wireless access network; according to the result of DHCP procedure the wireless access network makes relevant process for the dynamical IP address. By the invention, even though the DHCP server is an entity in the external network, the relevant resources in the access network can be released.

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...
