Title:	Supplementary Service Survey Report

Document for:	Information

___________________________________________________________________________

As the result of T2 #4 meeting, Panasonic is assigned to survey the supplementary service situation in 3GPP, so that it is proceeded to attended S1(Service) meeting held in Quebec, Canada on 5-9 July 99, T1 Signalling SWG meeting held in Edinburg, UK on 29-30 July 99 and TSG-C SS Adhoc meeting held in Bonn, Germany on 3-5 August 99.
Followings are the summary of these meetings which show the latest status in 3GPP.

1. S1 meeting

1	Description in 22.100(UMTS phase 1 release) on SS

6.1	Teleservices and supplementary services

Supplementary Services : The standard shall support GSM Release '99 supplementary services. The control of such supplementary services shall be the same as for GSM, from the user's perspective.

� Description in 22.105(Service and service capabilities) on SS

4.3	Supplementary services
A supplementary service modifies or supplements a basic telecommunication service. Consequently, it cannot be offered to a user as a stand alone service. It must be offered together or in association with a basic telecommunication service. The same supplementary service may be applicable to a number of basic telecommunication services.
Two methods are used for the characterisation of supplementary services;
-	The first method is used for the description of existing standardised supplementary services. These services are specified through the detailing of each of the operations involved in service provision and service usage (the provision/withdrawal, registration/erasure, activation/deactivation, invocation and interrogation operations). Clause 7 lists these services.
-	The second method enables the provision of HE/SN specific supplementary services. To make this possible, standardised building blocks referred to as service features are specified in clause 8. The combination and parametrisation of these service features allow the creation of supplementary services.
UMTS shall be able to handle multiple supplementary services within a call. Interactions shall be handled when several supplementary services are activated in the same call.. When multiple supplementary services can be activated concurrently, some prioritisation of the services will be necessary. Certain services may override or deactivate other services.
Interactions between operator specific supplementary services are not defined.
The following issues need consideration when interactions between services occur;
-	Different phases of a call.
-	A service spanning on more than one network.
-	Service interactions that may occur between services offered to a single user, as well as between services offered to different interacting users.
NOTE:	The methods defined for characterisation of services are description methods. They do not imply or restrict different implementations

7	Supplementary Services
Supplementary services are used to complement and personalise the usage of basic telecommunication services (bearer services and teleservices). The capabilities standardised in UMTS shall enable all the supplementary services specified in GSM 02.04 and the 02.8x set to be provided.

2. T1 Signalling SWG

Following table is prepared in T1 WG as for supplementary services.

Editor’s note: Rows 1 to 20 as in GSM. These are the supplementary services from 11.10-2. In GSM 02.04 R’99 there are some others services; do we have to include them also

3. TSG-C SS Adhoc meeting

According to the basic policy that supplementary services follow the GSM specifications, the followings are informed by SS Adhoc group.
