    • A method and system for selecting a gateway and a gateway selection execution node in the mobile packet domain are disclosed. The method includes: encapsulating, by a gateway selection execution node upon reception of a bearer setup request transmitted from a User Equipment, an operator domain name corresponding to the bearer setup request into a DNS parse request when creating the DNS parse request, and transmitting the DNS parse request to a DNS server; parsing by the DNS server for obtaining the address of an access gateway; returning by the DNS server, to the gateway selection execution node, a DNS parse result containing the address information of the access gateway corresponding to the operator domain name; selecting by the gateway selection execution node according to the address information the access gateway corresponding to the operator domain name as the access gateway corresponding to the bearer setup request.
    • 公开了一种用于在移动分组域中选择网关和网关选择执行节点的方法和系统。 该方法包括:在创建DNS解析请求时,由网关选择执行节点在接收到从用户设备发送的承载建立请求时,将与承载建立请求对应的运营商域名封装成DNS解析请求,并且发送 DNS解析请求到DNS服务器; 由DNS服务器解析获取接入网关的地址; 由DNS服务器返回到网关选择执行节点,包含对应于运营商域名的接入网关的地址信息的DNS解析结果; 由网关选择执行节点根据地址信息选择与运营商域名对应的接入网关作为对应于承载建立请求的接入网关。
