SIST EN 301 489-7 V1.3.1:2006(Main)
Electromagnetic compatibility and Radio spectrum Matters (ERM); ElectroMagnetic Compatibility (EMC) standard for radio equipment and services; Part 7: Specific conditions for mobile and portable radio and ancillary equipment of digital cellular radio telecommunications systems (GSM and DCS)
ETSI EN 301 489-7 V1.3.1 (2005-06)

The present document, together with EN 301 489-1 [1], covers the assessment of radio equipment meeting Phase 1, Phase 2, and Phase 2+ GSM and DCS digital cellular mobile and portable radio equipment transmitting and receiving speech and/or data, and operating in digital cellular radio telecommunications systems, and associated ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port and emissions from the enclosure port of radio equipment are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for Phase 1, Phase 2, and Phase 2+ GSM and DCS digital cellular mobile and portable radio equipment, transmitting and receiving speech and/or data, and associated ancillary equipment. Examples of digital cellular mobile and portable radio equipment covered by the present document are given in annex A. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and EN 301 489-1 [1], the provisions of the present document take precedence. Base station equipment (BTS and BSS) operating within network infrastructure is outside the scope of the present document. However, the present document does cover mobile and portable equipment that is intended to be operated in a fixed location while connected to the AC mains (see clause 5.5). The environment classification and the emission and immunity requirements used in the present document are as stated in EN 301 489-1 [1], except for any special conditions included in the present document.

TThe purpose of this third edition European Telecommunication Standard (ETS) is to present the possible architectures of the mobile system. Clause 3 of this ETS contains a definition of the different functional entities needed to support the mobile service. In clause 4, the confi guration of a PLMN is described as well as the organization of the fun ctional entities; the configuration presented is the most general in o rder to cope with all the possible implementations which can be imagin ed in the different countries. To illustrate that purpose, some exampl es of possible configurations are presented. Clause 5 of this ETS cont ains a brief description of the interfaces involved which shows the pr inciple of the organization considered.

Digital cellular telecommunications system (Phase 2+) (GSM); Specification of the Cordless Telephony System Subscriber Identity Module for both Fixed Part and Mobile Station (GSM 11.19 version 7.0.3 Release 1998)
ETSI EN 302 409 V7.0.3 (2000-08)

The present document defines the aspects of the internal organization of the FP-SIM which are related to the CTS initialization and CTS enrolment operation phase of CTS as well as the files contained in the SIM for dedicated CTS operation . This is to ensure interoperability between a FP-SIM and a CTS-FPE independently of the respective manufacturers and operators. The present document defines: -the contents of the files required for the CTS application; -the application protocol. All information regarding the interface between the Fixed Part Subscriber Identity Module (FP-SIM) and the Cordless Telephony System Fixed Part Equipment (CTS-FPE) mentioned below are fully compliant with the TS-GSM11.11 [12] unless otherwise stated in this present document.  -the requirements for the physical characteristics of the FP-SIM, the electrical signals and the transmission protocols; -the model which shall be used as a basis for the design of the logical structure of the FP-SIM; -the security features; -the interface functions; -the commands.  For more details regarding CTS, refer to specifications GSM 02.56 [3]and GSM 03.56 [6].  The present document does not specify any aspects related to the administrative management phase. Any internal technical reallocation of either the FP-SIM or the CTS-FPE are only specified where these reflect over the interface. It does not specify any of the security algorithms which may be used.

SIST ETS 300 500/A1 E1:2003(Amendment)
European digital cellular telecommunications system (Phase 2); Principles of telecommunication services supported by a GSM Public Land Mobile Network (PLMN) (GSM 02.01)
ETSI ETS 300 500/A1 ed.1 (1995-03)

REASON: Amendment 1 to ETS 300 500 due to a potential contradiction between GSM 02.01 and GSM 02.03 related to the negotiation from TS61 to TS62. Currnetly, if a TS61 call setup cannot be supported then it shall be negotiated to TS62. However, before this can be done a subscription check must be completed which, according to GSM 02.01, will fail. CONSEQUNCES OF NON-ACCEPTANCE: If this change is not accepted, then a subscription check for TS61 will cause the call to fail despite the fact that the call has a good chance of being sucessfully completed.

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.
