1 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 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 document 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 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.
The 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 assignment, 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 requirements 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 band 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. 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 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.

---------------------- Page: 6 ----------------------
3GPP TR 43.026 version 9.0.0 Release 9 6 ETSI TR 143 026 V9.0.0 (2010-02)
Backwards compatibility by the multiband MSs shall also be ensured. The MSs shall therefore be able to, functionally,
work as single band mobiles in a single band network.
2.4 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 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 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
specifications 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 MS 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 MS's frequency bands of
operation. The MS shall therefore, at PLMN selection, present all available 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 possible 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 bands 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 issues 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).
