Number automatic routing method, updating method, withdrawing method, router and device

摘要

A number automatic routing method, an updating method, a withdrawing method, a router and a device is provided wherein the number automatic routing method includes: converting to-be-distributed number into number routing information to add to dynamic routing protocol; generating a dynamic routing protocol message according to the number routing information; transmitting the dynamic routing protocol message through an Internet Protocol (IP) network and distributing the number through the dynamic routing protocol message and the IP network. The method supports automatic routing of numbers such as E.164 and E.214 and SP through expanding current Multi-Protocol Border Gateway Protocol (MP-BGP) that optimizes network structure and improves efficiency.
