46、erprise Services (HES) refers to a solution where an NGN hosts all business communication capabilities to a set of endpoints connected to a plurality of access points to this network. This type of network solution is also known as IP Centrex. In the simplest configuration all endpoints are connected
47、 to a TISPAN NGN IP-CAN. Endpoints may be SIP phones or legacy phones (Analogue or ISDN) connected to a gateway. All services by HES are provided by application servers using standard IMS procedures. User may access services that are specific to the enterprise they belong to as well as services avai
48、lable to any other IMS users. In more complex configurations some of the endpoints may be connected to a 3GPP IPCAN and/or a circuit-switched network, which is itself connected to the IMS via an MGCF. Endpoints connected to heterogeneous access networks may be served by the same HES. Endpoints serve
49、d by a HES shall have the ability to setup a session, identifying the communication target by: - a SIP URI of the form user domain; - an E.164 telephone number; - a number within a private numbering plan; - local service numbers. With regard to supplementary services, HES have strong similarities with the provision of PSTN/ISDN simulation services, although the actual set of services may be different. Examples of services that are enabled by the architecture described in the present document are: - All commonly used PSTN/
