Patent ID: 8787206

Claim:
A multi-address space mobile network system, comprising: a core network (CN) and edge networks (ENs), wherein the CN and the ENs are configured to adopt independent address spaces, and each EN is connected to the CN through a core edge router (CER); wherein a Domain Name Server (DNS) is configured to be set in the CN and is configured to store a first mapping relationship between a host name and a host identifier (HI); wherein the CN comprises a tangible non-transient computer-readable medium, including a distributed hash table (DHT) set in the computer-readable medium, and the DHT includes computer-executable instructions for: receiving registration information sent by a host through the CER, storing or updating a second mapping relationship between the HI and a CER identifier (ID), storing or updating a third mapping relationship between the HI and host location information, and storing or updating a fourth mapping relationship between the CER ID and CER location information in the CN; wherein the CER comprises a tangible non-transient computer-readable medium, the computer readable medium including computer-executable instructions for: advertising the EN connected to the CER of a default route reaching the CN; forwarding the registration information from the host to the DHT; and receiving a query message from the host, querying in the DHT according to the query message, and returning a query result to the corresponding host; wherein the first mapping relationship is absent from the DHT; and wherein the second mapping relationship, the third mapping relationship, and the fourth mapping relationship are absent from the DNS.
