Above-mentioned optimal path can be terminal pass through synchronous NAP can be directly connected to the path of its HNSP.Certainly, this optimal path also can be according to other as price factor, or other factors are determined, optimal path determining cause element really can set in advance in terminal, then terminal can according to the optimal path that wherein is provided with determine factor determine to pass through synchronous NAP whether exist optimal path to be connected to its HNSP.Here the optimal path that is connected to the HNSP of terminal may have more than one, as determined optimal path in the terminal is that terminal inserts the path that the back price is lower than certain predefined value, may there be many in such path, as long as then terminal has been found a path of satisfying this optimal path condition, be the optimal path of having found to be connected to HNSP.
After finding to be connected to the optimal path of HNSP, terminal can be connected to HNSP by this optimal path.
The present invention can be applied in the system of WiMAX and 3GPP interconnection, and then above-mentioned terminal can be a multimode terminal, both can set up synchronously and was connected by WiMAX mode and NAP, also can by 3GPP mode and NAP foundation synchronous be connected.
Below be applied in the system of WiMAX and 3GPP interconnection by the present invention and describe the present invention in detail as specific embodiment.
In specific embodiments of the invention, comprise WiMAX subscriber card and 3GPP subscriber card in the terminal, then terminal both can be passed through WiMAX mode access network, also can pass through 3GPP mode access network.
In addition, in advance at the pairing network equipment of NAP, in the base station, storage and this NAP are with the information of other NAP that cover in the present embodiment.For the network of WiMAX and 3GPP interconnection, the information of other NAP that comprised among the NAP comprises the information that belongs to the NAP of same system with this NAP, also comprises the information that belongs to the NAP of different system with this NAP.The information of the NAP here comprises the precedence information of NAPID or frequency point information and NAP.
Present embodiment based on system as shown in Figure 4, comprise terminal, have, and a plurality of NSP with a plurality of NAP that cover.Wherein the pairing network of NAP can be WiMAX ASN or 3GPP AN, and the pairing network of NSP can be WiMAX CSN or 3GPP network, comprises the HNSP of terminal among a plurality of NSP.The quantity of WiMAX ASN, 3GPP AN, WiMAX CSN and 3GPP network all can be N among the figure, and wherein N is more than or equal to 1.If between the WiMAX CSN, signed roaming agreement between the 3GPP network and between WiMAX CSN and the 3GPP network, then can interconnect communicates.
In the present embodiment, the corresponding NAP of each WiMAX ASN, and have network insertion supplier sign (NAP ID); The corresponding NAP of each 3GPP AN, receive the frequency point information of this 3GPP AN in terminal after, terminal be that this 3GPP AN constructs a NAP ID.
Passing through synchronous NAP with the optimal path by terminal in the present embodiment, to be directly connected to its HNSP be example, then terminal carry out that network is found and the flow process of carrying out network selecting as shown in Figure 5, may further comprise the steps:
Terminal selects wireless system to carry out according to the priority of the wireless system that is provided with in self, and the wireless system that is connected in the time of also can selecting last time wireless connections connects employed wireless system as this.Here, if terminal synchronous NAP belong to the WiMAX system, terminal can directly be obtained NAP ID from broadcast; If terminal synchronous NAP belong to the 3GPP system, then terminal is NAP ID of this NAP structure according to this NAP frequency points corresponding information.
In this step, if here terminal synchronous NAP belong to the WiMAX system, the same covering NAP information request message that terminal sends can be terminal basic capacity request message (SBC_REQ), then need add access information inquiry message (AIQ) in SBC_REQ, the form of AIQ can be as shown in table 1.
| Title (Name) | Type (Type) | Length (Length) | Value (Value) | Category (Scope) |
| AIQ | 20 | 1 | Empty (NULL) | SBC_REQ |
Table 1
After step 503, base station receive this information request message with covering NAP, be handed down to terminal with this place, base station NAP information of other NAP of covering together by response message with what store in self.
At SBC_REQ, response message mentioned in this step can be terminal basic capacity response message (SBC_RSP), then need in SBC_RSP, add and insert identification information (Access IdentityInformation, AII), AII is a compound type lengths values (tlv), comprise NAP ID or the frequency point information of one or more NAP with other NAP that cover, its form is as shown in table 2.
| Name | Type | Length | Value | Scope |
| AII TLV | 21 | 3*n | Comprise n, 24 the NAP that is inserted is with the NAPID or the 3GPP frequency point information that cover other NAP, and n is greater than or equal to 1 | SBC_RSP |
Table 2
In the present embodiment, if NAP has initiatively issued the wherein information of other NAP of the same covering of storage by the base station to terminal, then terminal need not execution in step 502 and 503, but after the information of other NAP that receive the same covering that NAP initiatively issues direct execution in step 504.In the WiMAX system, terminal can initiatively will be handed down to the information of other NAP that cover by above-mentioned SBC_RSP message in the base station among the NAP.
Step 504, terminal receive with terminal after the NAP of preamble information with other NAP that cover, generate access network sign priority list according to the information of these NAP.
In this step, for the frequency point information in the information of NAP, terminal at first is the NAP structure NAP ID of this frequency correspondence, and according to the precedence information in the information of NAP, NAP ID is according to priority just generated the network identity priority list in proper order.The precedence information here can directly be the precedence information of NAP, also can be the terminal pricing information that inserts NAP etc., and for the latter, terminal determines to insert the priority height of the low NAP of price.
In this step, terminal can be obtained the information of the associated NSP of NAP by sending a request message to NAP, also can be passive the information of the NSP that issues of the broadcast of reception NAP by the base station.
In addition, if in the implementation of this step or before this step, terminal by broadcast received this NAP of initiatively issuing of synchronous NAP with the information of other NAP that cover, then this terminal can be upgraded access network sign priority list, directly returns execution in step 505 then.
Whether step 510, terminal judges can be directly connected to the HNSP of this terminal by the NAP when preamble, if execution in step 511; Otherwise return execution in step 508.
In the implementation of above-mentioned steps 512 and step 513, terminal may occur and select a non-optimal path, but be connected to the situation of authentification failure behind the HNSP, under this situation, if there are many paths that are connected to HNSP, terminal can be selected next paths again, and carries out identifying procedure again, until authentication success; If authentification failure always after all possible path is all chosen then finishes this flow process.
Here, terminal is searched the method for the non-optimal path that can be connected to this terminal HNSP, can be according to the precedence information of NSP, or determine according to the precedence information of NAP or in conjunction with the precedence information of NAP and NSP.Wherein, the precedence information of NSP can be that terminal sets in advance in self, also can be included in above-mentioned flow process in the NSP information, be handed down to terminal by network side, terminal preferentially determines to be connected to the non-optimal path of this terminal HNSP according to the NSP precedence information that is provided with in self.The NSP precedence information that network side is handed down to terminal can directly be the precedence information of NSP, can be the relation of the HNSP of NSP and this terminal also, and for the latter, terminal can be determined the priority of NSP according to the roaming relationships of NSP and HNSP.
Suppose certain multimode terminal present located network condition as shown in Figure 6, wherein the HNSP of terminal is the 3GPP home network, the network equipment of the current NAP1 correspondence that connects of terminal is WiMAXASN#1, stored among this NAP with NAP2 that covers and the information of NAP3, wherein the pairing network equipment of NAP2 is 3GPP AN#1, and the pairing network equipment of NAP3 is 3GPP AN#n.Then after terminal has been obtained the information of NAP2 and NAP3 by NAP1, generate corresponding NAP ID.Suppose that terminal is according in the definite NAP priority list of price here, that priority is the highest is NAP1, is NAP2 secondly, is NAP3 at last.Here owing to being connected NAP1, terminal suffered, therefore need not to carry out synchronously and scanning with NAP1 again, the NSP information of then directly obtaining NAP1 and being connected comprises that specifically this NAP is direct-connected to NSP1, NSP2, and both sign the information that roaming agreement is arranged with the HNSP of terminal respectively; Terminal judges there is not optimal path according to these information; Then terminal is carried out synchronously and scanning with NAP2 again, and obtains the NSP information that NAP2 connects, and specifically comprises the direct-connected HNSP to terminal of NAP2, after terminal finds optimal path, is connected to its HNSP by this optimal path and authenticates.Here, if authentication success, terminal directly is connected to the HNSP of self by NAP2; Otherwise continuation is synchronous with NAP3, and flow process is after this carried out and can no longer be described here according to Fig. 5.
As can be seen, by the present invention, exist under the situation of optimal path from above-mentioned example, terminal has been found optimal path, and is connected to its HNSP by this optimal path; Rather than, promptly be connected to HNSP by this path as long as find to be connected to the path of HNSP.
More than be explanation, in concrete implementation process, can carry out suitable improvement, to adapt to the concrete needs of concrete condition method of the present invention to the specific embodiment of the invention.Therefore be appreciated that according to the specific embodiment of the present invention just to play an exemplary role, not in order to restriction protection scope of the present invention.
