Reason for 
change:
	Multiple connections for a single mobile could be realised through several calls. To support several calls, several parallel UMTS bearer services shall be possible to set up to circuit-switched networks (e.g. ISDN or PSTN) and to packet-switched networks (e.g.  IP).

comments:		

6)	Point to multipoint communication configurations as defined in TS 22.05 shall be supported by the phase 1 UMTS core network.
7)	The phase 1 UMTS core network shall support Multicall -feature. One or more of the following can achieve multicall: 
1. Several Circuit Switched calls share the same Circuit Switched bearer
2. Several Circuit Switched calls where each of the calls is mapped  to a separate Circuit Switched bearer
3. Several Packet Switched sessions are multiplexed on the same Packet Switched bearer
4. Several Packet Switched sessions where each of the sessions is mapped  to a separate Packet Switched bearer
Packet switched and circuit switched bearers are treated separately in multicall feature and may they take place simultaneously.
Note; In Release 99, bullet 2 does not apply for speech teleservice. However, Release 99 Call control should not prohibit a complete set of multiple speech bearer services in future releases. In Release 99, GSM SS Call Wait, Multiparty and Call Hold are used to offer simultaneous speech calls to user. 
 It is expected that the terminal and network capabilities will put some limitations on the number of bearer services that can be handled simultaneously. It shall be possible for each bearer to have independent traffic and performance characteristics.
8)	In order to facilitate the development of new applications, it shall be possible to address applications to/from a phase 1 UMTS mobile termination in connection oriented and connectionless traffic modes (e.g. the notion of Internet port).
9)	Operator specific services based on the VHE concept shall be provided by the phase 1 UMTS core network. This functionality could be provided through available toolkits (such as CAMEL, MExE, WAP and SIM Toolkit).
10)	 If UMTS authentication is invoked while a user has services active, the authentication shall not degrade the user services.
11)	 The phase 1 UMTS core network shall support the generation of standardised charging records based upon parameters such as the dialled number, call duration, traffic (volume, bit rate) and perceived Quality of Service provided to the user.
12)	 The phase 1 UMTS core network shall support on-line billing. Billing of 3rd party value added services with the concept of one-stop-billing shall be supported by the phase 1 UMTS core network through standardised procedures.
13)	 The phase 1 UMTS core network shall support both bilateral and (possibly via 3rd party) automatic roaming procedures to UMTS networks with improved security as defined by SMG10.
14)	 The phase 1 UMTS core network shall support interworking with PSTN, N-ISDN, GSM, X.25 and IP networks with their respective numbering schemes.
15)	 It shall be possible for the standardised classes of phase 1 UMTS mobile terminals supporting the GSM BSS and UTRAN radio interfaces to roam in GSM networks and receive GSM services.
16)	 Standardised protocols shall be defined for the operation, administration and maintenance of the UMTS phase 1 core network in cooperation with ETSI TMN.
17)	 The USIM requirements defined for later releases of UMTS should be taken into account in the design of the phase 1 UMTS core network.
9	USIM
In the first phase of UMTS, the USIM shall be developed on the basis of the phase 2+ release 99 GSM SIM. The additional requirements for the phase 1 UMTS USIM are as follows :
1)	USIM shall provide new and enhanced security features (e.g. mutual authentication...) as defined by SMG10.
2)	The UMTS mobile terminal shall support phase 2 and phase 2+ GSM SIMs as access modules to UMTS networks. The services that can be provided in this case may be limited to GSM like services provided by that UMTS network. UMTS mobile terminals shall not support 5V SIMs. It shall be up to the UMTS network operator to accept or reject the use of GSM SIM as access modules in its network.
3)	It shall be possible to have multiple applications on the UMTS IC Card (UICC). There shall be a secured and easy mechanism for application selection. An authorised access for each application is mandatory, however it shall be possible to have shared directories between applications where appropriate. The UICC shall be capable of supporting SIM and USIM applications.
4)	Simultaneous activation of several USIMs on one mobile terminal need not be supported in UMTS phase 1.
