9、nications and Internet Protocol Harmonization Over Network (TIPHON). Introduction The objective of ETSI Project TIPHON is the specification of interoperability mechanisms and related parameters to enable multimedia communications to take place, to a defined quality of service, between circuit switch

10、ed networks and Internet Protocol (IP) based networks and their associated terminal equipment. The TIPHON environment has been divided into 4 interrelated scenarios as described in TR 101 300 13. The present document defines the initial requirements for scenario 1, which is limited to real time voic

11、e communication between IP based terminais and terminals attached to circuit switced networks such as, Public Switched Telephone Network (PSTN), Integrated Services Digital Network (ISDN) and Global System for Mobile communications (GSM) terminals, in which the call set-up is originated by the IP te

12、rminal user. Other types of real time multimedia communication such as video, facsimile and data, conferencing and messaging services are not included. These are for further study. It is recognized that the present document will require further amendment and extension to take account of further work

13、 and experience of scenario 1. It is intended that there will be further revisions of the present document. STD-ETSI TR 101 30h-ENGL 1998 D 3900855 02b7570 3b5 5 TR 101 306 Vl.2.3 (1998-02) 1 Scope The present document defines the mandatory and optional TIPHON requirements to ensure service interope

14、rability for TIPHON scenario 1 systems (see clauses 6 to 10). This version of the present document specifies real time voice communications between users on Internet Protocol (IP) based networks and users on circuit switched networks where the call is originated on an IP based network. This is illus

15、trated in figure 1. IP network to PSTNKSDNIGSM voice, data and video conferencing; and messaging services are not included in the current version of the present document. It should be noted that where a requirement is optional or marked for further study in the first release of the present document,

16、 this does not preclude the possibility that such a requirement may become mandatory in a future version of the present document. 2 References References may be niade to: a) specific versions of publications (identified by date of publication, edition number, version number, etc.), in which case, su

25、ess of collecting the call information data for purposes of attributing costs between service providers or network operators. authentication: The process of proving identity within its context. This normally entails proving the possession of a secret (uniquely associated with the identification) to

26、the authenticator. authorization: The process of granting permission on the basis of identity, to access or use a service, or to access information. Authorization is performed by the entity that controls the resource, and, if payment is required, that same entity is responsible for accounting to the

27、 customer or other party. backward call clearing: An ability for the called party to release a call during the call. - STD-ETSI TR 101 3Ob-ENGL 1778 3LI00855 02b7572 138 7 TR 1 O1 306 Vi .2.3 (1 998-02) basic call: See the definition for call. billing: The process of presenting the user with a reque

28、st for payment e.g. based on network usage; possibly including supporting information such as call records. call: Point-to-point communication between two endpoints. The call begins with the call Set-up procedure and ends with the call termination procedure. A call may be directly between two endpoi

29、nts, or may include other H.323 entities such as a gatekeeper or Multipoint Control Unit (MCU). Typically, a call is between two users for the purpose of communication, but may include signalling-only calls. An endpoint may be capable of supporting multiple simultaneous calls. charging: The process

30、of determining the amount of money a user shall pay for usage of a certain service. collect call: Call paid for by the called party. Caller indicates a request for a collect call and the service provider asks the called party to accept. credit card call: Calls charged to a credit card user. director

31、y service provider: A provider of directory information e.g. providing an E. 164 number from an emdl address. E.164 number: The international telephone number (as defined in ITU Recommendation E.164 i) composed of a variable length of decimal digits arranged in specific code fields as following: Cou

32、ntry Code i- National Destination Number + Subscriber Number eavesdropper: An unauthorized listening only participant in a communications channel. firewall: A device (computer or software or both), used to restrict and monitor usage of computer(s) or the network. forward call clearing: An ability fo

The Gatekeeper may also provide other services to the terminals, Gateways, and MCUs such as bandwidth management and Gateway location. gatekeeper service provider: An IP service provider who offers services available from gatekeepers to the user. g

35、ateway (GW): For the purposes of the present document, a gateway is understood to mean an H.323 gateway, as defined below. H.323 gateway: An H.323 GW is an endpoint on a network which provides for real-time, two-way communications between H.323 Terminals on an IP based network and other terminals on

36、 a switched circuit network. identification: An entity has identification within a specific context, and may therefore possess multiple identities; one for each context in which it must be known. Ail identities within a particular context must be unique. An Identification may consist of a simple str

37、ing, or a name within a directory mechanism. identity: Information which uniquely identifies the user. Network operators require proof of identity for billing. Users require proof of identity before discussing sensitive information. Applications (e.g. audio response units) require proof of identity

38、before allowing information to be accessed. interconnectivity provider: A service provider who offers services for access between iP and ISDN/PSTN/GSM networks. Internet Protocol (IP) access provider: A company or organization which provides their customers with access to an IP network. IP address:

39、Each network unit connected to an IP network must have a unique internet or IP address. Todays IP addresses is based on IPv4 and are 32-bit numbers with its predefined structure. The IP address (IPv4) is written as four decimal numbers separated by a point. IP broker: Provider of a business service

IP endpoint: A device that originates or terminates the IP based part of a call. Endpoints include H.323 c

41、lients, and IP telephony gateways. IP network provider: A company or organization which provides access to an IP network. IP service provider: A company or organization which provides access to IP services which could be either access to a private IP network (Intranet) or to the Internet. IP telepho

42、ny service provider: A service provider who offers telephony services over IP networks IPv4: The existing standard for IP, which uses a 32-bit address field. IPv6 (or IPng): The next generation of IP, which uses a 128-bit address field. Malicious Call IDentication (MCID): MCD is a supplementary serv

43、ice offered to the called party which enables the called party to request that the calling party be identified to the network and be registered in the network. network operator: An organization which operates a telecommunications network. non-repudiation: A security function that provides proof of t

44、he origination of information and serves as a deterrent to the originating party falsely denying the information. premium rate call: Calls made to access particular information, or services, for which an additional charge is made. The service provider charges the caller for the used services accordi

45、ng to predefined rate. privacy: The characteristic that only authorized entities are capable of access; e.g. eavesdropping is prevented. PSTN/ISDN/GSM end user: A user who accesses the PSTN/ISDN/GSM services provided by Telecom companies. PSTN/ISDN/GSM network provider: A company providing either PS

46、TN, ISDN, or GSM network services. value added service provider: Service provider which provides services beyond normal or traditional services. The extra services are normally informational services and are not part of the services which are offered traditionally by service providers. 3.2 Abbreviat
