3 Definitions and Abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
User-to-User Information (UUI): The information transferred by using the UUS supplementary service.
UUS service: The UUS services (Service 1, 2 and 3) are components of the UUS supplementary service. If the UUS
supplementary service is provided to a subscriber, she can handle the UUS services independently within a call.
Served subscriber: The subscriber who has a provision of the UUS supplementary service and who activates the UUS
supplementary service. For service 1 and 2 the served subscriber is always the calling subscriber, for service 3 either the
calling or the called subscriber can be the served subscriber.
Remote party: For service 1 and 2 the remote party is the called party of a call to which the UUS supplementary service
is activated by the served subscriber. For service 3 the remote party can be either the called or the calling party of an
established call to whom the use of the UUS supplementary service is requested by the served subscriber.

4 Description
4.1 Description
The UUS supplementary service allows the served subscriber to send/receive a limited amount of subscriber generated
information to/from another user in association with a call to the user. This information shall be passed transparently
(i.e. without modification of contents) through the network. Normally, the network shall not interpret or act upon this
information.
The served subscriber can send and receive UUI in different phases of the call depending on the service(s) to which the
subscriber subscribes. These services are:
Service 1: UUI can be sent and received during the origination and termination of a call, with UUI embedded
within call control messages. The service 1 can be activated implicit by inserting UUI when set-up
a call or explicit with an appropriate procedure.
Service 2: UUI can be sent and received after the served subscriber has received an indication that the remote
party is being informed of the call and prior to the establishment of the connection. UUI sent by the
served subscriber prior to receiving the acceptance of the call by the remote party, may as a
network option be delivered to the remote party after the call has been established. The service 2
shall be activated explicitly.
Service 3: User-to-user-information can be sent and received only while the connection is established. The
service 3 shall be activated explicitly.
Service 1, service 2 and service 3 shall allow the transmission of UUI with the maximum length of 128 octets per
message.
4.2 Applicability to telecommunication services
The applicability of this supplementary service is defined in GSM 02.04 [2].
5 Normal procedures with successful outcome
5.1 Provision
The UUS supplementary service shall be provided to the served subscriber after pre-arrangement with the service
provider. The remote party needs no subscription of the UUS supplementary service.
NOTE: The remote party is able to send UUI without provision of the UUS supplementary service when the
service is activated against her by the served subscriber.
As a service provider option, one or any combinati
