25、15.0.0 (2018-07)63GPP TR 43.026 version 15.0.0 Release 151 Scope The purpose of the present document is to describe the functionality of a Multiband GSM/DCS Network operated by a single operator and the Multiband GSM/DCS Mobile Station (MS). It also describes the necessary amendments to the GSM/DCS
26、phase 2 specifications for the technical realization of the function. The resulting Amendment Requests (AR) and Change Requests (CR) necessary for Multiband Operation are listed in annex A. 1.1 References Not relevant to the present document. 1.2 Abbreviations Abbreviations used in the present docum
27、ent are listed in GSM 01.04. 2 General Multiband operation of GSM/DCS by a single operator enables an operator, with licenses in more than one of the frequency bands specified in the GSM specifications, to support the use of multiband MSs in all bands of the licenses. In addition it also enables the
28、 operator to support the use of single band MSs in, at least, one band of the licenses. Multiband GSM/DCS MSs, are MSs which are capable of using more than one of the frequency bands specified in the GSM specifications. The multiband MS is specified in GSM 02.06. (AR02.06-A001) and in section 2.1. T
29、he use of multiband operation and development of multiband MSs are optional for operators and manufactures. 2.1 Multiband MSs A MS which supports more than one band and the functionality below is defined as a Multiband MS. The multiband MS has the functionality to perform handover, channel assignmen
30、t, cell selection and cell re-selection between all its bands of operation within one PLMN, i.e. when one PLMN code is used in all bands. In addition it has the functionality to make PLMN selection, in manual or automatic mode, in all its bands of operation. The multiband MS shall meet all requireme
31、nts specified for each individual band supported. In addition it shall meet the extra functional requirements for the multiband MSs. 2.2 Frequency bands of operation Multiband operation shall be possible with any combination of the frequency bands specified in the GSM specifications. No frequency ba
32、nd is treated as a primary band in the specification. The operators may however use control mechanisms to make the MSs treat one of the bands with priority. As a first implementation of Multiband operation only operation with GSM 900 (Standard or Extended) and DCS 1 800 is included in the standard.
33、The proposed procedures shall however make it possible for operation between other bands if such are included in the core specifications in the future. 2.3 Backwards compatibility Backwards compatibility with phase 1 and phase 2 single band mobiles shall be ensured by the specification of multiband
34、operation. A multiband PLMN shall therefore, in addition to support of multiband MSs, be able to support the use of single band mobiles for, at least one of the bands of operation. Backwards compatibility by the multiband MSs shall also be ensured. The MSs shall therefore be able to, functionally, w
35、ork as single band mobiles in a single band network. ETSI ETSI TR 143 026 V15.0.0 (2018-07)73GPP TR 43.026 version 15.0.0 Release 152.4 PLMN codes Multiband operation of GSM/DCS by a single operator, with handover and assignment between the bands, implies that only one PLMN code is used in all bands
36、 of operation. Handover or assignment between PLMNs is not covered by this document or the work item. An operator, with license in more than one band, may however support multiband mobiles without handover and assignment between the bands. If so, more than one PLMN code may be used. This is already
37、covered with the phase 1 and phase 2 specifications. 2.5 Other systems Multiband operation by a single operator does not include multi mode operation, i.e. handover, assignment or roaming between GSM/DCS and systems covered by other specifications or standards. The amendments of the GSM/DCS specific
38、ations for multiband operation may however be done in a flexible way so that multi mode operation can make use of the same procedures. 3 Requirements 3.1 User requirements No special actions by the user shall be necessary to use a multiband MS. The possibility for the user to decide to operate the M
39、S in a single band mode may however be supported. Indications may also be given to the user of which band is being used. The user of a multiband MS shall be able to roam between PLMNs operating in any of the MSs frequency bands of operation. The MS shall therefore, at PLMN selection, present all ava
40、ilable PLMNs within its frequency bands of operation. 3.2 Operator requirements The use of multiband operation shall be optional for the operator. Multiband MSs must therefore be able to, functionally, work as single band MSs in a single band network. When multiband operation is used, it shall be po
41、ssible to provide coverage in one frequency band independently of the coverage in another band Two options can be implemented by an operator when operating a multiband network : i) a BCCH in each band of operation; ii) a common BCCH in only one of the band of operation when resources across all band
42、s are co-located and synchronized. NOTE: For case ii), in order to ensure proper operation of the network, the operator should take into account issues related to the difference of propagation between the different bands, e.g GSM and DCS when performing cell planning. As far as synchronization issue
43、s are concerned, the requirements for TA for multiband BTSs may only be fulfilled when the TA is the same in the two bands, i.e. within the tolerance as defined in GSM 05.10. This imposes some restrictions on the cells where the two bands are supported (e.g. small cells). 3.3 Radio requirements The
44、radio requirements for GSM and DCS in the present GSM/DCS specification differs in some cases. A multiband MS and the multiband network shall meet all requirements for each band of operation respectively. Type approval of multiband MSs will be covered by the respective test specifications and some a
45、dditional tests for the multiband functionality. ETSI ETSI TR 143 026 V15.0.0 (2018-07)83GPP TR 43.026 version 15.0.0 Release 153.4 Relation to frequency hopping The multiband MS and the multiband network shall support frequency hopping within each band of operation. Frequency hopping between the ba
46、nds of operation is not required. 4 Functional description To understand the necessary amendments of the phase 2 specifications functional descriptions of different procedures and solutions are described below. The technical realization are described in clause 5 and the actual amendments are listed
47、in annex 1 with a brief description. 4.1 Idle mode procedures The idle mode procedures will not be different for multiband MSs or networks. Only the fact that more than one band is available has to be taken into account. 4.1.1 PLMN selection A multiband MS shall use the normal PLMN selection procedu
48、res, as specified in GSM 02.11 and 03.22, with the additional requirement to select from all available PLMNs in all bands of operation. When presenting available PLMNs it shall show all available PLMNs within the MSs bands of operation. A multiband PLMN may have BCCHs available on more than one band
49、 but shall still be treated as one PLMN and must therefore only be presented once. PLMN search time, at switch on, will be the sum of the search times presently specified for each band of operation if no prior knowledge is stored in the MS. 4.1.2 Cell re-selection The multiband network will send out neighbour cell lists which may contain a mixture of channels from different frequency bands. The multiband MSs shall follow the normal cell-re-selection procedures with the addition to monitor all channels within the neighbour cell list which are within the MSs bands of operatio
