19、he requirements in the present document are based upon the recommendations described in TR 101 750 2. TIPHON covers both the provision of voice related services on IP and the interworking and interconnection with circuit switched technologies. The TIPHON architecture has been developed as an abstrac
20、t model in TS 101 3 14 (see bibliography). TIPHON separates the provision of service from the provision of transport and so offers the capability for a user to register from any geographical location and to use any access network which may be located in any geographical location. The identities used
21、 by those entities providing transport may not have a deducible relationship to the identities used by those entities providing service. Lawful Interception of the media stream in a TIPHON environment is provided by the transport plane and may take place in the access network used by the target or i
22、n any other network that carries the traffic of the target using an identity provided by the TIPHON application plane. TIPHON has identified an application environment model shown in figure 1. In the example shown, there are three Service Capabilities, A, B and C. These are distributed across the TI
23、PHON network and service environment model and instantiated as Co, CT2 and CT etc. Lawful interception is one of these distributed service capabilities. Figure 1 : Service Capabilities interworking across domains Table 1 gives a list of the access technologies for which lawful interception requireme
24、nts have been defined. Table 1 also lists the identifiers for targets that are used in the documents listed.

25、 IAS for GSM for release 99 Within each technology there may be more than one concurrent identity being intercepted (for example an equipment may be intercepted rather than an individual (target as IMEI rather than IMSI. or one of a set of teleDhone numbers (taraet as MSISDN rather than IMSI. Requir
26、ements have not yet been specified for xDSL access and access on dedicated circuits such as leased lines, which will be used widely for access to TIPHON networks. Where the access technologies are circuit switched but are used to carry IP packets, for example IP over ISDN, then the circuit switched
27、technology shall provide lawful interception.
