The first situation, as shown in Fig. 2, there are associated access points for the first website, and the second website, there is no when associated access point, the first website carries out the home site during end-to-end bidirectional data transfers as the first website and second station point.
Since home site is responsible for obtaining to associated access point for transmitting number between website in data transmission procedure According to resource, therefore home site there must be associated access point.
Second situation, as shown in Figure 3, there is associated access point in the first website and the second website, and when the first website and the identical associated access point of the second website, and the first website carries out the home site during end-to-end bidirectional data transfers as the first website and second station point.
Optionally, the second website can also be used as the first website and second station point carries out home site during end-to-end bidirectional data transfers.
The third situation, as shown in Figure 4, there is associated access point in the first website and the second website, and first website and when the not identical associated access point of the second website, first website carries out the home site during end-to-end bidirectional data transfers as the first website and second station point, and the cancellation of the second website is associated with access point.
During end-to-end bidirectional data transfers, since priority of the associated access point of the second website to the instruction of the second website is higher than home site to the priority of the instruction of the second website, the associated access point of the second website can generate interference to the data transmission procedure website to the instruction of the second website.To prevent this interference, so that the data preferentially executed between home site and the second website are transmitted, then needs the second website to cancel and be associated with access point.
Optionally, the second website can also be used as the first website and second station point carries out home site during end-to-end bidirectional data transfers, needs the first website to cancel at this time and is associated with access point.
Optionally, the first website sends the request message of the data transmission link for requesting the second website to be established between the first website to the second website, includes information of first website as home site in request message；First website receives the response message for confirmation request message of the second station replies.
Second of implementation, the first website inform the first website as home site by the second website.
Specifically, reception the second website transmission of the first website is used to notify the first website as the notification message of home site, the first website determines itself as home site according to the notification message.
