Reason for 
change:
	The destination of emergency call is different for police station or fire brigade, using two different numbers in Japan (i.e. *110* for police and *119* for fire brigade). It is required to support the capability to identify of emergency call for police or fire brigade in call/connection control.

5.2. Bearer services
UMTS phase 1 shall support GSM phase 2+ Release '99 data bearer services :
Circuit switched data: Circuit switched data services and "real time" data services shall be provided for interworking with the PSTN/ISDN so that the user is unaware of the access network used (UMTS and GSM access network or handover between access networks). Both transparent (constant delay) and non-transparent (zero error with flow control) services shall be supported. These data services shall operate with minimum loss of data on handover between the GSM access network and the UTRAN.
Packet switched data: Packet switched data services shall be provided for interworking with packet networks such as IP-networks and LANs. The standard shall provide mechanisms which ensure the continuity of packet based services upon handover e.g. between GSM and UMTS.
5.3	Emergency call
UMTS shall support an emergency call teleservice and support the following service requirements:
-	It shall be possible to identify a particular speech call as an emergency call to the serving network.
-	It shall be possible to initiate an emergency call whether or not the USIM is present (although in this case a default emergency number may be required).
-	It shall be possible for the serving network to obtain the number the user has input and route the call appropriately (in particular a serving network that supports one emergency call centre may ignore the user's selection of  destination).
When the USIM is present:
-	It shall be possible to select from at least two optional numbers for the emergency call (i.e. police station, fire brigade etc. in the countries/regions where more than one emergency destination is provided).
When no USIM is present at least the GSM default emergency number(s) will be supported, the possiblity to support other numbers is for further study.
