4 User services
4.1 General service assumptions
The User Equipment (UE) will typically be realized as a separate satellite mobile terminal, which may be connected to
other user devices such as an external telephone and/or computer, as shown in Figure 4.1. To make use of the network
services, users insert their GSM/GPRS/UMTS subscriber identity module (SIM/USIM) into the UE and connect an
external telephone handset and/or computer/PDA to the UE via a wireless or cabled connection.

Figure 4.1: Typical Satellite Network Set-up and Services
The satellite network will offer users the ability to make and receive telephony and ISDN calls via the directory
telephone number(s) associated with their subscriber identity module (SIM) issued by their home network. Users may
also be offered an "always-on" Internet/Intranet connection with fixed or dynamically assigned IP addresses (depending
on their subscription).
Data rates and connection options provided to users are dependent on the design and class (i.e.
pocket/notebook/briefcase size) of user equipment.
The satellite network operator (or Service Providers/Distribution Partners) will provision the suite of communication
services offered to users via the satellite network.
4.2 Circuit switched services
4.2.0 General
The Core Network provides speech telephony, 3,1 kHz audio or UDI/RDI circuit switched (CS) data services to mobile
users (UDI/RDI are the ISDN Unrestricted and Restricted Digital Information services, respectively).
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TS 102 744-1-1 V1.1.1 (2015-10)
Due to constraints within the core network, the satellite network can support the operation of a maximum of one circuit
switched call per subscriber (IMSI) at any time. The operation of one or more Internet/GPRS sessions operating
concurrently with a single circuit switched call (such as telephony or CS data) to a single subscriber is supported.
The directory telephone number(s) of the user will be those associated with their SIM/USIM subscription in their home
network.
4.2.1 Circuit Switched Speech - Basic Telephony Service
The satellite network shall offer speech telephony services. A user may make outgoing and receive incoming speech
telephone calls and may make use of a wide range of supplementary services (e.g. calling line ID, call waiting, etc.).
To make use of the service, a user connects an external telephone handset to the UE. The means of connecting the
handset (e.g. 2/4 wire socket, Bluetooth, ISDN socket, etc.) is dependent on the features of the UE.
Telephone keypad and display capability depends on the features of the chosen UE type and connected equipment.
Initial user equipment does not use the voice coding technique specified by 3GPP (the Advanced Multi Rate codec,
AMR). User equipment instead transmits and receives speech via a satellite optimized low data-rate codec that makes
efficient use of satellite capacity whilst maintaining toll level speech quality. Conversion is carried out in the Core
Network to ensure interoperability with other networks.
The satellite network incorporates the capability of supporting other codecs (including AMR) to ensure compatibility
for future UE types.
4.2.2 Circuit Switched Voice - Emergency Calls
The satellite network shall support mobile originated emergency voice calls to designated Public Service Access Points
(PSAPs). The Core Network may be configured by the operator/service provider to enable emergency calls to be made
without a USIM/SIM card in the user equipment as described in ETSI TS 124 008 [i.25], clause 4.5.1.5. In addition the
RNS may be configured by the operator to transmit a control flag broadcast in the system information which affects the
UE behaviour (i.e. whether or not it may register without USIM). This feature is further described in ETSI
TS 102 744-3-6 [i.24].
The user equipment (or the Core Network) shall recognize the dialled number as a designated "emergency number" and
indicate to the network that an emergency call is required. The network shall route the Emergency Call to the PSAP
appropriate to the geographical position reported by the user equipment. The core network incorporates the capability to
report the GPS coordinates of the calling user to the called PSAP.
4.2.3 Circuit Switched Data - ISDN UDI/RDI (Unrestricted/Restricted
Digital Information)
Selected UE types may offer the capability to initiate and receive ISDN UDI/RDI circuit switched data calls using a
single 64 kbit/s channel per subscriber for user plane traffic.
In order to make use of this service some UE designs may feature an integrated or peripheral "basic-rate" ISDN socket
with an S/T bus (allowing the UE to act as the network terminating device, NT-1). The socket allows users to connect
standard ISDN end-user equipment conformant to the Euro-ISDN Basic Rate standard and make outgoing and incoming
ISDN UDI/RDI data calls through the satellite network.
The satellite network may support the ISDN UDI/RDI service by providing one 64 kbit/s "B Channel" per user and may
prohibit a user operating other circuit switched services at the same time as ISDN.
RDI user plane transmission is handled in the satellite network as per UDI, i.e. with a guaranteed bit rate of 64 kbit/s.
A potential additional application for the UDI/RDI service is for transporting circuit-switched video conferencing traffic
encoded using the 3G-H324M suite of encoding standards (the standards proposed for real-time mixed media circuit-
switched calls over 3G mobile networks), as described in ETSI TS 126 110 [i.6]. In cases where the User Equipment
does not have built in audio/video capability, the software/hardware for encoding, decoding and presenting these
transmissions is assumed to be provided in the equipment attached to the UE.

11 ETSI TS 102 744-1-1 V1.1.1 (2015-10)
4.2.4 Circuit Switched Data - 3,1 kHz Audio
The preferred data service for users is the GPRS Packet Switched service. It is anticipated that the majority of users will
use the GPRS Packet Switched service for data and facsimile transmission.
To provide a capability to support legacy modem and facsimile users, the satellite network may offer a service to carry
PCM cod
