1 Scope
This TS defines the stage one description of the General Packet Radio Service (GPRS). Stage one is an overall service
description, primarily from the service subscriber's and user's points of view, but does not deal with the details of the
human interface itself. This TS includes information applicable to network operators, service providers and terminal,
switch and data base manufacturers.
This TS contains the core requirements for the packet switched networks specified by 3GPP which are sufficient to
provide a complete service. It defines a set of bearer services that provide packet mode transmission within the PLMN
and interwork with external networks.
The term GPRS shall be used in this document to refer the GPRS service offered via GERAN and UTRAN and the PS
Domain of the 3G PLMN.
The GPRS shall not prevent the user's operation of other 3GPP services.

4 Main Concepts
The GPRS allows the service subscriber to send and receive data in an end-to-end packet transfer mode, without
utilizing network resources in circuit switched mode.
GPRS enables the cost effective and efficient use of network resources for packet mode data applications e.g. for
applications that exhibit one or more of the following characteristics:
- intermittent, non-periodic (i.e., bursty) data transmissions, where the time between successive transmissions
greatly exceeds the average transfer delay;
- frequent transmissions of small volumes of data, for example transactions consisting of less than 500 octets of
data occurring at a rate of up to several transactions per minute;
- infrequent transmission of larger volumes of data, for example transactions consisting of several kilobytes of
data occurring at a rate of up to several transactions per hour.
Within the GPRS, two different bearer service types are defined. These are:
- Point-To-Point (PTP);
- Point-To-Multipoint (PTM).
Based on standardized network protocols supported by the GPRS bearer services, a GPRS network administration may
offer (or support) a set of additional services. This is outside the scope of this specification, however, a number of
possible PTP interactive teleservices include:
- retrieval services which provide the capability of accessing information stored in data base centres. The
information is sent to the user on demand only. An example of one such service in the Internet's World Wide
Web (WWW);
- messaging services which offer user-to-user communication between individual users via storage units with
store-and-forward mailbox, and/or message handling (e.g., information editing, processing and conversion)
functions;
- conversational services which provide bi-directional communication by means of real-time (no store-and-
forward) end-to-end information transfer from user to user. An example of such a service is the Internet's Telnet
application;
- tele-action services which are characterized by low data-volume (short) transactions, for example credit card
validations, lottery transactions, utility meter readings and electronic monitoring and surveillance systems.
Some examples of teleservices which may be supported by a PTM bearer service include:
- distribution services which are characterized by the unidirectional flow of information from a given point in the
network to other (multiple) locations. Examples may include news, weather and traffic reports, as well as
product or service advertisements;
- dispatching services which are characterized by the bi-directional flow of information from a given point in the
network (dispatcher) and other (multiple) users. Examples include taxi and public utility fleet services;
- conferencing services which provide multi-directional communication by means of real-time (no store-and-
forward) information transfer between multiple users.
Some examples of teleservices which may be supported by either PTP or PTM bearers include:
- user subscribed services where a priori agreement is made for delivery of data to a user, such as stock quotes,
sports results, specific product or service advertisements, and email.
EGPRS is an enhancement of GPRS for GERAN allowing higher data rates on the radio interface. The same set of
services provided by GPRS is available in EGPRS.
HSDPA is an enhancement to Packet data services for UTRAN allowing higher data rates on the radio interface
downlink. The same set of services provided by GPRS is available with GPRS using HSDPA.

5 Service Requirements
5.1 GPRS reference model
The GPRS can be described using the simplified reference model in figure 1.
GPRS provides data transfer capabilities between a sending entity and one or more receiving entities. These entities
may be an UE or a Terminal Equipment, the latter being attached either to a GPRS network or to an external data
network. The base station provides radio channel access for UEs to the GPRS network. User data may be transferred
between four types of UEs as described in 3GPP TS22.001 [1] and TS 24.002 [2].
Each PLMN has two access points, the radio interface (labelled Um for GERAN and Uu for UTRAN) used for mobile
access and the R reference point used for origination or reception of messages. The R reference point for the UEs is
defined in 27.060 [9].

5.1.3 (Void)
5.2 Network Interworking
Network interworking is required whenever a PLMN and a non-PLMN are involved in the execution of a GPRS Service
request.
ETSI
3GPP TS 22.060 version 10.0.0 Release 10 12 ETSI TS 122 060 V10.0.0 (2011-05)
In general the mobile user of a GPRS network will receive and experience all the services provided by an external data
network. In this case the external data network refers to the network that the GPRS PLMN interworks with as
determined by the network operator. With this in mind it can be said that a user :-
1) will require a universal identity(ies) of the form compatible with the interworked with network(s);
2) and experience access to and provision of all services as offered by the interworked with networks (some
reduction of capability may result from unavoidable restrictions due to the complexity of implementation).
5.2.1 Interworking with other data networks and other PLMNs
GPRS shall provide means to interwork with external data networks. The GPRS operator may provide an appropriate
address to the external data network for the subscriber as part of the GPRS subscription. That address can be either
dynamic (e.g. the user's IP address is allocated from a pool of unused IP addresses every time the subscriber activates
the access to an IP network) or static (e.g. a certain IP address is permanently allocated to a particular subscriber). In
addition, the GPRS network shall be able to notify the server IP address (e.g. the gateway IP address) to the subscriber,
when the subscriber activates. When connected with some external data networks, the routeing protocols of these
networks may limit the data network addresses that can be allocated. For example, when interworking with IP networks,
the IP address for the GPRS subscriber shall belong to that GPRS operator's IP subnetwork that allocates the address. In
the case of a simple point to point connection, a GPRS subscriber need not have an associated network address.
The type of interworking between a PLMN and data networks is determined by the network operator.
Interworking with the following types of data networks shall be defined:
- IP networks;
- other PLMNs, directly or via a transit network.
5.2.1.1 QoS when Interworking
GPRS shall satisfy, within the constraints introduced by the mobile radio environment, the QoS requirements of the
interworked-with network.
5.2.2 GPRS Numbering Plan
It is required that GPRS UE addresses conform to the numbering plan already defined for 3GPP system.
5.2.3 Addressing and routeing requirements
5.2.3.1 PTP network layer services
A GPRS subscriber identified by an IMSI, may have a network layer address(es) temporarily and/or permanently
associated with it that conforms to the standard addressing scheme of the respective network layer service used, e.g.:
- IP Version 4 and 6 addresses for Internet CLNS.
In the case of a simple point to point connection, a GPRS subscriber need not have an associated network layer
address.
5.2.4 Interworking for subscriber roaming
Interworking between different GPRS PLMNs is required in order to support subscriber roaming.
It shall be possible for the VPLMN to provide access to the external data network when the external non-3GPP data
network address is dynamically assigned by the VPLMN.
5.3 GPRS service description
There are two categories of GPRS services:
ETSI
3GPP TS 22.060 version 10.0.0 Release 10 13 ETSI TS 122 060 V10.0.0 (2011-05)
- Point to Point (PTP) services,
- Point to Multipoint (PTM) services.
The PTP service provides a transmission of one or more packets between two users, initiated by a service requester and
received by a receiver.
There is one PTP service: - PTP Connectionless Network Service (PTP-CLNS). The PTM service provides a
transmission of packets between a service requester and a receiver group.
There is one PTM service:
- IP Multicast (IP-M).
An invocation of the service request by a service requester is possible from the fixed and mobile access points.
Table 1 presents the relationship between service requests and the Service Requester/Receiver.

NOTE 1: It shall be possible to transfer data between two mobiles of the same operator without the use of
external data networks.
5.3.1 Point-To-Point Connectionless Network Service (PTP-CLNS)
Point-To-Point Connectionless Network Service (PTP-CLNS) is a service in which one (or more) single packet(s) is
(are) sent from a single service subscriber "A" to a single destination user "B". Each packet is independent of the
preceding and succeeding packet. This service is of the datagram type and is intended to support bursty applications. On
the radio interface PTP-CLNS supports the acknowledged transfer mode for reliable delivery.
GPRS provides data communications services consistent with the connectionless network layer service definition ISO
8348 [3]. Specifically, GPRS shall be able to support applications based on the following network layer protocol:
- Internet Protocol (IP);
- IP is the network layer protocol of the Internet TCP/IP protocol suite defined by Internet STD 5 [4].

5.3.3 Point-To-Multipoint (PTM) service overview
A PTM service is the transmission of a single message to multiple subscribers. The GPRS PTM services provide the
capability for a subscriber to send data to multiple destinations.
There is one PTM service:
- IP Multicast (IP-M), which is a service defined as a part of the IP protocol suite. In IP-M messages are sent
between participants of an IP-M group. An IP-M group can be internal to the PLMN or distributed across the
Internet. Participation and data transfer in the IP-M service shall be compliant with the Internet protocols. See
RFC 1920 [4], RFC 1458 [4], RFC 1301 [4] and RFC 1112 [4]. The Service Receiver of a point-to-multipoint

service request shall be able to filter out packets at a network level, through use of the Packet Identities, which
are of no interest either because they are for a service for which no subscription is held, or the packet belongs to
a sub-group within the offered application service which is of no interest. It is required that the UE-Application
resources shall not be utilized for this function.

5.4 Service interworking
It shall be possible for the GPRS PTP services to be utilized as a bearer service for the SMS-MO and SMS-MT
services.
5.5 Transfer Characteristics
The packet multiplexing mechanisms developed for GPRS shall be independent of a given channel type. It shall be
possible to operate GPRS over low and high capacity channels. Table 3 is only applicable to the GPRS part of the
connection.

c) Flexible channels with a maximum bit rate that depends on the type of channel and the number of time slots in
GERAN that are used. This capability defines the maximum capability associated with the channel(s). The actual
bit rate for a particular user may be any value up to this maximum value.
d) Establishment of communication: may be on demand, reserved or permanent.
5.6 Service characteristics
5.6.1 Subscriber profile
The subscriber profile holds subscription information about services and other parameters that have been assigned for
an agreed contractual period. It includes the following information:
- subscribed services (PTP-CLNS);
- subscribed QoS profile (service precedence(priority), reliability, delay, throughput).
An invocation of a service by any user with the appropriate subscription profile shall be possible.

It shall be possible to validate a service request against a service subscriber's subscription profile.
5.6.2 Quality of Service (QoS)
The mapping of user application QoS parameters to GPRS QoS parameters is an implementation issue and is not part of
GPRS specifications.
It shall be possible to respond to local data traffic conditions adaptively. GPRS shall include the functionality to
increase or decrease the amount of radio resources allocated to GPRS on a dynamic basis. The criteria used to decide on
dynamic changes of the GPRS part of the radio resource should not be specified. Thus, only the necessary procedure,
including radio protocol and timers, needed to perform the change of radio resources shall be specified within the ETSI
specifications.
Within GPRS the dynamic allocation of th
