Embodiment 1

[0094] Embodiment 1, the decision point is MS. see Figure 4 shown, including the following steps:

[0095] Step 1. During the network access process, the MS performs EAP authentication. When the EAP authentication succeeds, the H-CSN sends an Access-Accept message, which contains the H-CSN's policies and capabilities.

[0096] Step 2: The Access-Accept message passes through the V-CSN, and the AAA agent of the V-CSN adds the policies and capabilities of the V-CSN to the message and sends it to the ASN.

[0097] Step 3: If the MS initiates the DHCP process first, the ASN sends the H-CSN, V-CSN, and the policies and capabilities of the ASN to the MS in a DHCP-REPLY message; it can also be sent in an EAP message notifying the MS of successful authentication to MS.

[0098] Step 4, after the MS obtains the above strategies and capabilities, it makes a decision according to its own strategies and capabilities, and finally selects a mobile IP mode.

[0099] Step 5, after the D...

Embodiment 2

[0102] Embodiment 2, the decision point is the ASN. see Figure 5 shown, including the following steps:

[0103] Step 1. During the network access process, the MS performs EAP authentication. When the EAP authentication succeeds, the H-CSN sends an Access-Accept message, which contains the H-CSN's policies and capabilities.

[0104] Step 2: The Access-Accept message passes through the V-CSN, and the AAA agent of the V-CSN adds the policies and capabilities of the V-CSN to the message and sends it to the ASN.

[0105] In step 3, the MS notifies the network side of the MS' policies and capabilities through a router request message RS.

[0106] Step 4: After the ASN obtains the above-mentioned strategies and capabilities, it makes a decision according to its own strategies and capabilities, and finally selects a mobile IP mode.

[0107] Step 5, if it is PMIP6 and the ASN has not obtained the home network prefix before, you need to initiate the PBU / PBA process to obtain it. T...

Embodiment 3

[0109] Embodiment 3, the decision point is the ASN. see Image 6 shown, including the following steps:

[0110] Step 1. During the network access process, the MS performs EAP authentication. When the EAP authentication succeeds, the H-CSN sends an Access-Accept message, which contains the H-CSN's policies and capabilities.

[0111] Step 2: The Access-Accept message passes through the V-CSN, and the AAA agent of the V-CSN adds the policies and capabilities of the V-CSN to the message and sends it to the ASN.

[0112] In step 3, the MS notifies the network side of the MS' policies and capabilities through a DHCP message (DHCP-Information-Request / DHCP-Request / DHCP-Solicit).

[0113] Step 4: After the ASN obtains the above-mentioned strategies and capabilities, it makes a decision according to its own strategies and capabilities, and finally selects a mobile IP mode.

[0114] Step 5, ASN sends DHCP-REPLY to MS, if it is PMIP or simple IP mode, the HA address is not included in...

Abstract

The invention discloses a method for choosing a mobile IP mode in a wireless network, a wireless network and a decision-making entity, which uses strategy and ability of a comprehensive network side and an MS side to choose the mobile IP mode. The method of the invention comprises that: a decision node obtains the strategies and abilities of the network side and a mobile station MS and chooses one strategy and ability from the intersection of the strategies and abilities of the network side and the mobile station MS; the decision node correspondingly chooses the mobile IP mode according to the chosen strategy and ability and notifies the network sides and / or the MS. The wireless network of the invention comprises the network side, the mobile station MS and a decision-making unit used for obtaining the strategy and ability of the network side and the MS, choosing one strategy and ability from the intersection of the strategy and ability of the network side and the MS, correspondingly choosing a mobile IP mode according to the chosen strategy and ability and notifying the chosen mobile IP mode to the network sides and / or the MS.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for selecting a mobile IP mode in a wireless network, a wireless network and a decision-making entity. Background technique [0002] At present, on the WiMax wireless network (not limited to the Wimax network), there may be different MSs and different user requirements for the MS side. Some terminals do not support MIP6 mode, and some users choose CMIP6 / PMIP6 / Simple IP6 mode for specific reasons. For the network side, there may be specific requirements for PMIP6 and CMIP6 modes. For example, operators can specify a certain MS or all MSs to use only PMIP6 or simple IP6 mode according to their own characteristics or user characteristics; another example: Since CMIP6 also requires the cooperation of terminal capabilities, the network side cannot restrict MSs that do not support CMIP6 to use CMIP6 mode; another example: operators can formulate policies according to their own chara...
