The informationpertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be foundin SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in respectof ETSI standards", which is available free of charge from the ETSI Secretariat. Latest updates are available on theETSI Web server (http://www.etsi.fr/ipr or http://www.etsi.org/ipr).Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guaranteecan be given as to the existence of other IPRs not referenced in SR 000 314 (or the updates on the ETSI Web server)which are, or may be, or may become, essential to the present document.ForewordThis European Standard (Telecommunications series) has been produced by ETSI Technical Committee NetworkAspects (NA).In analogy with CCITT Recommendations I.130 [6], the first stage of the following three level structure is used todescribe the telecommunications services as provided by European public telecommunications operators:-Stage 1: is an overall service description, from the service subscriber’s and user’s standpoint;-Stage 2: identifies the functional capabilities and information flows needed to support the service described instage 1; and-Stage 3: defines the signalling system protocols and switching functions needed to implement the servicedescribed in stage 1.The present document details the stage 1 aspects (overall service description) for the Cordless Terminal Mobility (CTM)service, taking into account the various network architectures, e.g., Intelligent Network (IN).The application of stage 2 and stage 3 may be different when the service is supported on an IN environment.National transposition datesDate of adoption of this EN:7 August 1998Date of latest announcement of this EN (doa):30 November 1998Date of latest publication of new National Standardor endorsement of this EN (dop/e):31 May 1999Date of withdrawal of any conflicting National Standard (dow):31 May 1999SIST EN 301 175 V1.1.1:2003



ETSIEN 301 175 V1.1.1 (1998-08)71ScopeThe present document defines the stage 1 service description for phase 1 of the Cordless Terminal Mobility (CTM)service. Stage 1 is an overall service description, primarily from the service subscriber’s and user’s point of view, butdoes not deal with the details of the human interface itself. The present document includes information applicable tonetwork operators and terminal, switch and database manufacturers.The present document specifies the requirements where the service is provided to the CTM user via atelecommunications network that is either the pan-European Integrated Services Digital Network (ISDN) or a PublicSwitched Telephone Network (PSTN) as provided by European public telecommunications operators.The present document includes interworking requirements for cases where users in a call are located on differentnetworks.The provision of the CTM service on mobile networks is outside the scope of the present document.The present document contains the core requirements for phase 1 of the Cordless Terminal Mobility (CTM) service. Aservice may be provided on the basis of these core requirements alone.The present document also documents some optional service features which may be used to enhance the service.Furthermore, additional functionalities not documented in the present document may be implemented. The requirementsof which are considered outside of the scope of the present document and consequently outside the scope of thecorresponding stage 2 and stage 3 standards. Such additional functionality may be on a network-wide basis, or particularto one CTM user or a group of CTM users. Such additional functionality does not compromise conformance to the corerequirements of the service.Charging principles are outside the scope of the present document, unless specific service requirements are stated. Theserequirements deal with the allocation of certain call charges to particular CTM users.Interactions with services/supplementary services not listed in clauses 8 and 9 are outside the scope of the presentdocument.The Cordless Terminal Mobility (CTM) service allows users of cordless terminals to be mobile within and betweennetworks. Where radio coverage is provided and the cordless terminal has appropriate access rights the CTM user isable to make calls from, and to receive calls at, any location within the fixed public and/or private networks, and maymove without interruption of a call in progress.Phase 1 of the Cordless Terminal Mobility (CTM) service is applicable to the telephony 3,1 kHz teleservice (see ETS300 111 [2]). Phase 1 of the CTM service is also applicable to the speech bearer service (see ETS 300 109 [3]) and the3,1 kHz audio bearer service (see ETS 300 110 [4]).If the present document is applicable to the stage 2 and stage 3 standards for the phase 1 of the CTM service, where thetext indicates the status of a requirement (i.e. as strict command or prohibition, as authorization leaving freedom, as acapability or a possibility), this shall be reflected in the relevant stage 2 and stage 3 standards. Otherwise, the status of arequirement shall be reflected in the relevant standards for the underlying protocols. Furthermore, conformance to thepresent document is either met by:-conforming to the stage 3 standards; or-implicitly covered by conforming to the standards for the underlying protocols,with the field of application appropriate to the equipment being implemented. Therefore no method of testing isprovided for the present document.SIST EN 301 175 V1.1.1:2003

ETSIEN 301 175 V1.1.1 (1998-08)9core service feature: Particular service feature fundamental to the telecommunication service, i.e., in the absence of thisservice feature, the telecommunication service does not make sense as a commercial offering to the service subscriber.coverage area: The area within the radio coverage area in which the user has subscribed to use the CTM service.CTM identity: The identity by which a user is known to the CTM service providers and networks supporting CTM, andit is used for flexibility and security purposes. The CTM identity identifies a CTM user unambiguously. The CTMidentity does not need to be known by users.CTM number: A number that uniquely and unambiguously identifies each user.
