3.1 Terms and Definitions

The following terms and definitions apply to this document.

3.1.1

Location Server the device has an IP connection, it knows what to PSTN gateway can be used to terminate a call. It is involved in the function TRIP the main functional entities responsible for completing calls between end users and the telephone network, and the dissemination of information to the gateway server elsewhere.

3.1.2

Telephony Routing Information Base Established and maintained by the LS for saving routing information database TRIP protocol interaction.

3.1.3

IP telephone management domain IPtelephonyadministrativedomain Set under a single administrative authority control domain resources, such as the gateways, servers, etc. The end user is ITAD customers.

3.1.4

Polymerization aggregation Polymerization is to merge multiple routes into one route to the same destination address contains the set to reduce the size of the telephone routing information database and send Get TRIP routing information number.

3.1.5

Coarse and precise routing X and Y are the two routes, each destination is reachable through routing if Y can also reach the route X, and X and Y are not the same, then it indicates that the route Y routing more precise than X.
