US 2014/0064217 A1 · METHOD FOR PROVIDING IMS SUPPORT FOR ENTERPRISE PBX USERS

Abstract

An architecture and procedures by which an NGN can provide the following capabilities to an NGCN user: basic terminating service in the peering model; enhanced terminating services in the peering model; enhanced originating services in the peering model; and roaming service in the subscription and peering models. All capabilities are provided in an easily scalable manner via provisioned subscriber data and small modifications to existing IMS procedures. In one embodiment, an NGN is configured among the external networks to receive all SIP requests intended for the NGCN users of an NGCN interconnected to the NGN via the peering model (this NGN is the trunking home NGN), and the NGN forwards these requests to the NGCN for handling using request retargeting.

Claims9

Dependent claims

A method of providing roaming service for a user in a Next Generation Network (NGN), the method comprising:

assigning to one or more users in a Next Generation Corporate Network (NGCN) a Session Internet Protocol (SIP) registrar name whose domain is assigned within a public Domain Name System (DNS) to a roaming home NGN;
and
within a subscriber database, provisioning a public user identity (PUID) assigned to an NGCN user having roaming capability with an alternate registrar, wherein the alternate registrar contains an address at which the NGCN server can be reached with a registration request message.

Dependencies are inferred from the claim text.
