SIST EN 301 113 V6.3.1:2003

• Abstract:

  SUBJECT Allowing re-negotiation of the QoS parameters for throughput during a session improves the flexibility of network operation and increases the quality of service perceived by the user. Requirement for the MS to inform the network of its GPRS class is not appropriate for the stage 1 and should be left for the stage 2 to determine. The three MS classes A, B, C remain unchanged. Clarification of the GPRS Attach characteristics. A GPRS-Attach shall be succesfully performed only if the subscriber has a valid GPRS subscription.

SIST EN 301 113 V6.3.1:2003 is the ETSI stage 1 service description for General Packet Radio Service (GPRS) on GSM Phase 2+. It specifies the user-facing GPRS service model, point-to-point packet services, QoS, security, roaming, charging-related information and interworking for network operators, service providers and equipment manufacturers.

What does SIST EN 301 113 V6.3.1:2003 specify?

SIST EN 301 113 V6.3.1:2003 defines the overall GPRS service from the subscriber’s and user’s point of view. It gives the service description for GSM networks, while leaving detailed human interface behavior, external applications, and general charging policy outside the document’s service rules.

The document is organized into clauses 1 to 11 and one informative annex.

Annex	What it covers
A	Change request history

What are the key requirements of SIST EN 301 113 V6.3.1:2003?

• Clause 4 positions GPRS as a set of GSM bearer services for packet-mode transmission within the PLMN and for interworking with external networks. In practice, this means GPRS is defined to coexist with other GSM services rather than replace them.

• Clause 5.2 defines two point-to-point services: PTP-CLNS and PTP-CONS. PTP-CLNS is datagram-like and supports independent packets, while PTP-CONS supports a logical connection that can last from seconds to hours and can be used for X.25-style traffic.

• Clause 5.3 and 5.4.2 make the service adaptable to network conditions. The document allows dynamic allocation of radio resources and re-negotiation of throughput during a session, so the network can adjust capacity for bursty traffic and file transfers.

• Clause 5.4.1, 6.1, 6.4 to 6.6 link service use to the subscriber profile. A subscriber profile holds the subscribed services and QoS profile, and registration, erasure, interrogation, activation and de-activation let the user tune those parameters within the subscription limits.

• Clause 5.4.2.1 defines QoS in terms of service precedence, reliability, delay and throughput. This matters because the network uses those categories to treat traffic differently under congestion and to control how much delay, loss or rate variation an application can expect.

• Clause 5.4.3 and 5.4.11 cover security and message screening. The document provides for MS authentication, access control, user identity confidentiality and user information confidentiality, and it also allows screening to filter unauthorized or unwanted messages.

• Clause 5.4.5, 5.4.6, 5.4.7 and 5.4.8 cover MS class behavior, roaming, subscriber numbering and battery-saving operation. The three MS classes A, B and C remain part of the model, roaming across networks is supported, subscriber numbering stays under PLMN control, and power-saving methods such as DRX can be used as long as QoS is maintained.

• Clause 6.3, 6.9 and 11 set the attach and interworking rules. GPRS-Attach succeeds only with a valid GPRS subscription, multiple GPRS sessions can run in parallel, and interworking with external data networks relies on assigned addresses and QoS that fit the external network within radio constraints.

What terms does SIST EN 301 113 V6.3.1:2003 define?

• General Packet Radio Service (GPRS) - the GSM packet-mode service for end-to-end data transfer.
• Mobile Station (MS) - the equipment that accesses GSM PLMN services and can operate as class A, B or C.
• Quality of Service (QoS) - the observed service performance at the access point, especially speed, accuracy and dependability.
• PTP-CLNS - point-to-point connectionless service for independent packets and bursty traffic.
• PTP-CONS - point-to-point connection-oriented service for a logical packet session.
• Service Data Unit (SDU) - the preserved unit of user data passed between peer layers.
• Temporary Link Level Identity (TLLI) - the temporary identity used by the MS on the radio path.

Who uses SIST EN 301 113 V6.3.1:2003?

GSM/GPRS network operators and service providers use this standard to define the services they offer, the subscriber profile they manage, and the interworking they support. Terminal, switch and database manufacturers use it to align equipment behavior with the stage 1 service model. Buyers and quality managers use it to check whether a solution supports the expected GPRS service classes, QoS handling, roaming and external network access.

What changed in SIST EN 301 113 V6.3.1:2003 from the previous edition?

SIST EN 301 113 V6.3.1:2003 updates version 6.3.0 for publication. The change history states these main changes:

• throughput QoS parameters can be re-negotiated during a session;
• the MS class reporting requirement is left to stage 2;
• GPRS-Attach is clarified so it succeeds only with a valid GPRS subscription;
• Class B mode of operation is clarified;
• an example is removed from the Stage 1 text.

Which standards are used with SIST EN 301 113 V6.3.1:2003?

• GSM02.01 and GSM04.02 - GSM service principles and access reference configuration.
• ITU-T X.25, ISO 8208, ISO 8348 and ISO 8878 - packet-level, connectionless and connection-oriented networking foundations.
• Internet STD5 - the IP suite used for Internet packet services.
• ITU-T X.3, X.28 and X.29 - PAD and asynchronous access procedures.
• ITU-T X.75 and Bellcore GR-000301 - packet-switched interworking between public networks.
• ITU-T X.121, X.136 and X.137 - numbering and public network performance values.
• GSM02.06, GSM02.04, GSM02.30, GSM02.17, GSM02.68, GSM03.68 and GSM04.68 - MS types, supplementary services, MMI, SIM characteristics and VGCS references used in the service model.

What does the SIST EN 301 113 V6.3.1:2003 document contain?

The document contains the GPRS reference model, the description of bearer services and teleservices, and the access points used for GSM and external network interworking. It also includes the QoS model, reliability and delay classes, transfer characteristics and the MS operating classes.

Later clauses cover provisioning, withdrawal, GPRS-Attach and GPRS-Detach, registration, erasure, activation, de-activation, invocation, PIN and password handling, addressing, service interworking and network interworking. The tables support those topics with transfer characteristics, reliability classes, delay classes, registration parameters and identity mapping.
