Choice manner of the access gateway in Mobile packet domain, the data accumulation node which accumulates

摘要

SolutionsThis invention Mobile packet domeingetouei selective method, releases the system and the gateway execution node. As for the above-mentioned method, as for the gateway selective execution node after receiving bearasetsutoatsupurikuesuto which the user device transmitted, the occasion where DNS analysis request is formed, encapsulating the enterprise domain name which corresponds to aforementioned bearasetsutoatsupurikuesuto during DNS analysis requesting, the step which it transmits to the DNS server, as for the DNS server the step which analyzes the address of the access gateway, as for the DNS server step and the aforementioned gateway selective execution node which send back the DNS analytical result where address information of the access gateway which corresponds to the aforementioned enterprise domain name in the gateway selective execution node is included selecting the access gateway which corresponds to the aforementioned enterprise domain name with the aforementioned address informationDoing, it includes with the step which it makes the access gateway which corresponds to aforementioned bearasetsutoatsupurikuesuto. As for this invention because it is possible, to decrease the restriction for the gateway selection of the DNS analytical server ahead roaming the DNS server of the enterprise ahead roaming does not accumulate the address information of the access gateway of the enterprise ahead foam/home location and the te, it is possible to select the access gateway of foam/home location because of the server terminal which roaming has been done.
