ETSI ETSI TS 142 056 V14.0.0 (2017-04)63GPP TS 42.056 version 14.0.0 Release 14Introduction Today, there exists a clear distinction between the public mobil
27、e telephone systems for wide area coverage on the one hand, and private cordless telephone systems for local area coverage on the other hand. Recently, attempts have been made to integrate the wide area cellular and the local area cordless function into one and the same Mobile Equipment (ME). Howeve
28、r, because of the incompatibility between the existing cellular and cordless standards, this results in ME implementations with rather low cost-efficiency. The intention of the GSM Cordless Telephony System (CTS) is therefore to provide cordless functionality to a standard GSM Mobile Station (MS) wi
29、th minimum impact on the MS. The impact would ideally be limited to an upgrade of the ME and SIM software. This can only be accomplished if the radio interface of the cordless system is identical, or very similar, to the standard GSM radio interface. ETSI ETSI TS 142 056 V14.0.0 (2017-04)73GPP TS 42
30、.056 version 14.0.0 Release 141 Scope The scope of the present document is to describe the Service aspects of a GSM Cordless Telephony System (CTS), which provides the possibility for users of GSM terminals to have cordless access to a fixed network, such as PSTN/ISDN or a radio network such as GSM.
31、 Due to the time constraints to have a first specification ready for market needs, a phased approach is necessary. The first phase aims primarily at an application supporting the speech teleservice (including DTMF support) in a residential single cell environment. The focus is on the requirements ne
32、cessary to elaborate the radio interface and the security aspects for such an application. To not prevent or impede the evolution of CTS to additional services and functions, later phases may have to be considered when now defining the means to fulfil the above mentioned requirements for the first p
33、hase of CTS. Therefore, additional support on the CTS radio interface for later phase services (e.g. SMS, subscriber authentication and GSM supplementary services), is included already in CTS Phase 1, provided that such services are clearly defined. Other expected services and functions in later pha
34、ses are included in annex A. The standardisation of the physical layers of the GSM-CTS fixed network interface is not in the scope of the present document. However, consideration may need to be given to communication of application data between CTS and PLMN via the fixed network. 2 References The fo

41、of the present document, the following terms and definitions apply: FP Enrolment: procedure where a CTS-FP is loaded with data necessary to obtain CTS operation. After this procedure CTS operation may commence. MS Enrolment: procedure where a CTS-MS is associated for the first time with a CTS-FP. Af
42、ter this procedure CTS-MS has access to this CTS-FP. Attachment: procedure where an MS attaches to a certain CTS-FP. When attached, it is possible to make and receive calls via the CTS-FP. The CTS-MS must have been initialised correctly to the CTS-FP before attachment can take part. Generic Frequenc
43、y List (GFL): Generic Frequency List (GFL) contains all absolute radio frequency channel numbers (ARFCN), as defined in GSM 05.05, on which the CTS-FP is allowed to operate. The CTS-FP will never use frequencies which are not listed in the GFL. CTS Mobile Station: GSM MS with CTS capability. CTS Fix
44、ed Part: CTS-FP is a device which offers a personnal cordless coverage and acts as a link between the CTS-MS and the fixed network or the GSM network. GSM Operator: GSM operator is the operator who provides GSM cellular service to the MS. CTS licence exempt frequencies: frequency band that may be al
45、located by national regulator to CTS usage outside of a GSM licence allocated to a GSM operator. CTS operator: CTS operator is the operator who provides the GFL to the CTS-FP. The CTS operator may be the same than the GSM operator. FP-SIM: FP-SIM is the SIM card inserted in the CTS-FP, which materia
46、lised the CTS subscription. The FP- SIM belongs to the CTS operator. CTS subscription: when a GSM licensed band is used, the right to use a CTS operators frequency spectrum for communication between a CTS-FP and CTS-MS(s). CTS-FP owner: person who has the CTS-FP control and may authorise MS Enrolmen
47、t. CTS user: person who has a CTS-MS which is allowed to do CTS operations. CTS-MS local number: number in the range of 0-99 optionally assigned to the CTS-MS at enrolment. This number is used for CTS internal calls. CTS-Roaming: right for an additional CTS-MS to be enrolled to a CTS-FP which is ini
48、tialised to an operator other than the HPLMN operator of the additional CTS-MS. 3.2 Abbreviations In addition to those below, abbreviations used in the present document are listed in GSM 01.04.
