`(57) Abstract
`
`The invention relates to a radio device for operation in at least two different radio systems having unequal bands of operat-
`ing frequencies represented by channels numbers. The device comprises a radio trasmitter (i); a radio receiver (2}; a frequency
`synthesizer (3) for generating local oscillator frequencies for the radio transmitter and radio receiver; respectively and a control
`means (4, 5} for controlling the frequency synthesizer {3) so as to look it to transmitting and receiving frequencies corresponding
`to a selected channel number. In the invention, the control means comprises a memory (5) for storing frequency synthesizer con-
`trol data of a single channel number for each different radio system, on the basis of which control data the control means is cap»
`able of deriving control data of any other channel number for the radio system in which the radio deVEce is currently operating.

`Radio device
`
`Field of the Invention
`
`The
`
`invention relates to a
`
`radio device for
`
`5
`
`operation in at
`
`least
`
`two different
`
`radio systems
`
`having unequal bands of operating frequencies
`
`re—
`
`presented
`
`by
`
`channel
`
`numbers,
`
`the
`
`radio device
`
`comprising a radio transmitter;
`
`a radio receiver; a
`
`frequency
`
`synthesizer means
`
`for generating
`
`local
`
`10
`
`oscillator frequencies for the radio transmitter and
`
`the radio receiver,
`
`respectively; and a control means
`
`for controlling the frequency synthesizer means so as
`
`to lock the synthesizer means
`
`to transmitting and
`
`receiving frequencies

`
`selected
`
`Background of the Invention
`
`In private automatic mobile radio networks or
`
`trunked networks, several user groups or even several
`
`20
`
`user organizations share the same radio channels and
`
`other resources in a common network. Typical private
`
`radio network applications include energy production
`
`and distribution,
`
`communal
`
`and municipal
`
`services,
`
`transportation, construction, maintenance,
`
`and emer—
`
`25
`
`gency
`
`services,
`
`such
`
`as police,
`
`fire alarm and
`
`ambulance. A private mobile radio network may offer
`
`fast
`
`access within
`
`the user‘s
`
`own organization,
`
`individual or group communication, data communica-
`
`tion, etc. The system checks the Subscriber author-
`
`30
`
`ization and allocates resources. An
`
`individual
`
`sub-
`
`scriber is unaware that he uses the same frequencies
`
`as other subscribers as the system automatically se—
`
`lects a free radio channel for a call during the call
`
`set-up. This kind of radio telephone systems usually
`have a rather limited geographical coverage,
`and so
`
`35
`
`@
`
`45».

`
`the user may easily get outside the service area of
`
`his own system,
`
`and thus cannot use his radio tele—
`
`phone. Therefore there has arisen a need to be able
`
`to use the same radio telephone in several different
`
`5
`
`systems.
`
`The specifications MPT 1327 and MPT 1343 issued
`
`by the British Ministry of Trade and Industry have
`
`become kind of de
`
`facto standards
`
`in Europe
`
`for
`
`private mobile
`
`radio networks. MPT
`
`1327
`
`specifies
`
`10
`
`signalling over
`
`the
`
`radio path, while MPT
`
`1343
`
`Specifies the operation and structure of
`
`the radio
`
`telephone. Systems
`
`complying with these specifica—
`
`tions have been and will be introduced in different
`
`European countries. All radio telephones used in the
`
`15
`
`different systems actually comply with the same MPT
`
`1343 specification, wherefore they can,
`
`in principle,
`
`be transferred from one radio telephone network to
`
`another by varying the network—specific radio tele—
`
`phone parameters complying with the MPT 1343.
`
`20
`
`The
`
`radio telephone
`
`systems usually employ
`
`special
`
`radio channel numbers
`
`in all
`
`internal
`
`sig—
`
`nalling for
`
`representing transmitting and receiving
`
`frequencies,
`
`i.e.
`
`radio channels, each channel number
`
`representing a certain pair of
`
`transmitting and re—
`
`25
`
`ceiving frequencies. A radio telephone or a similar
`
`radio device used in this kind of
`
`system converts
`
`each channel
`
`number
`
`internally into corresponding
`
`frequency synthesizer control data which controls the
`
`frequency synthesizer so as to cause it to be locked
`
`30
`
`to the transmitting and receiving frequency pair cor—
`
`responding to the channel number in the current radio
`
`‘
`
`system. When using the same radio telephone in dif—
`
`ferent
`
`radio telephone networks,
`
`problems may
`
`be
`
`caused by the fact
`e.g.
`channel
`1, may

`that
`correspond to different

`
`3
`
`quencies
`
`in different
`
`radio telephone systems,
`
`as
`
`illustrated in Figure 1.
`
`In Figure l,
`
`the frequency
`
`of the channel CHO of the radio telephone system A is
`
`410 MHz, while higher
`
`frequencies at
`
`intervals of
`
`5
`
`12.5 kHz or 25 kHz correspond to the other channel
`
`numbers. The channel numbering of
`
`the system B in
`
`turn is such that
`
`the frequency corresponding to the
`
`channel CHO is 420 MHz. As a consequence,
`
`the radio
`
`telephone cannot operate in both systems A and B as
`the channel numberings
`and frequency bands of
`the
`
`10
`
`systems do not match.
`
`Disclosure of the Invention
`
`The object of
`
`the invention is to provide a
`
`15
`
`radio device which is capable of operating in dif—
`
`ferent
`
`radio networks where the channel numberings
`
`and frequency bands do not correspond to each other.
`
`This is achieved by means of a radio device of
`
`the type described in the introductory chapter, which
`
`20
`
`according to the invention is characterized in that
`
`the control means comprises a memory means for stor-
`
`ing frequency synthesizer control data of
`
`a single
`
`channel number
`
`for each different
`
`radio system,
`
`on
`
`the basis of which control data the control means is
`
`25
`
`any other
`of
`data
`deriving control
`of
`capable
`channel number
`for
`the radio system in which the
`
`radio device is currently operating.
`
`The basic idea of
`
`the invention is that
`
`fre—
`
`quency synthesizer control data corresponding to a
`
`30
`
`single channel number
`
`is stored in the radio device
`
`a
`
`for each different radio system. The stored control
`
`data determines the physical
`
`frequency corresponding
`
`to said one channel number, and corresponding control
`
`data for the other channel numbers in the system are
`
`35
`
`derived therefrom. An advantage of
`
`the invention is
`

`

`VV()93/l6530
`
`PITT/Fl93f00047
`

`
`that
`
`the channel data stored for one channel number
`
`enables the channel numbering of the radio device to
`
`be shifted and aligned to the frequency band used by
`
`the
`
`radio system in which
`
`the
`
`radio device
`
`is
`
`5
`
`currently operating.
`
`The
`
`invention also enables
`
`a
`
`radio device operative ii} a nearly unlimited number
`
`of different
`
`radio networks
`
`to be
`
`realized very
`
`simply, advantageously and with a
`
`small
`
`requirement
`
`of memory capacity.
`
`In the preferred embodiment of
`
`10
`
`the invention the control data is the divisor of at
`
`least one frequency divider means contained in the
`
`frequency synthesizer means.
`
`In the preferred embodi—
`
`ment of
`
`the invention,
`
`the divisor corresponding to
`
`the channel number 0 is stored in the memory.

`
`A Detailed Description of the Invention
`
`In the radio device shown in Figure 2,
`
`such as
`
`a radio telephone, a baseband signal processing unit
`
`8 derives a modulating baseband transmitting signal
`
`BA from an audio signal 10A generated by a microphone
`
`30
`
`10 or
`
`an external
`
`audio or data signal TUE“. The
`
`derived transmitting signal
`
`is applied to a
`
`radio
`
`transmitter section 1
`
`in which it modulates a trans—
`
`mitting—frequency
`
`local oscillator signal
`
`fTX from a
`
`'
`
`frequency synthesizer unit
`
`3.

`
`PCT/FI93/00047
`
`5
`
`is applied through a duplex
`transmitter section 1
`filter to an antenna ANT.
`
`A receiving—frequency RF signal
`
`7A received by
`
`the antenna ANT is applied through a duplex filter 7
`
`5
`
`to a radio receiver section 2, where it is mixed in
`
`one or more mixing stages into a
`
`received baseband
`
`signal
`
`2A.
`
`A
`
`baseband
`
`signal processing unit
`
`9
`
`processes
`
`the signal
`
`2A so as
`
`to control
`
`a
`
`loud—
`
`speaker 11 or derives from it an audio or data signal
`
`10
`
`RDEXT to be applied to an external device.
`
`In the radio
`
`receiver
`
`section
`
`2,
`
`a
`
`receiving-frequency
`
`local
`
`oscillator signal f“ generated by the frequency syn—
`
`thesizer 3 is utilized for the high—frequency mixing,
`
`i.e. the first mixing stage.
`
`15
`
`The
`
`frequency
`
`synthesizer
`
`3
`
`cemprises
`
`two
`
`phase-looked loops
`
`for deriving the frequencies f”
`
`and fax
`
`from a
`
`reference frequency generated by a
`
`common crystal oscillator 36. The reference frequency
`
`:EREF of the crystal oscillator 36 is divided in phase
`
`20
`
`comparators 31 and 37 by a divisor M which is pro-
`
`the phase comparators'by a
`grammed in a register of
`control unit
`4 over
`a control bus
`4A. The
`local
`
`oscillator frequency f.m is applied to one input
`
`in
`
`the phase
`
`comparator
`
`31
`
`through a
`
`fixed or pro-
`
`25
`
`grammable frequency divider 35. The phase comparator
`
`31 generates a voltage proportional
`
`to the phase dif—
`
`ference between the two signals, which voltage is
`
`applied through a
`
`lowpass filter 32 to a voltage—
`
`controlled oscillator 33 to cause it to change the
`
`30
`
`output frequency f“ so that the phase difference de-
`
`fi‘
`
`creases. Correspondingly,
`
`the phase
`
`comparator
`
`3'7
`
`compares a frequency fmm with the local oscillator
`
`frequency fRx applied through a fixed or programmable
`
`frequency divider 41 and generates a voltage propor—
`
`35
`
`tional to the phase difference. The output voltage of

`

`

`
`6
`
`the phase comparator 37 is applied through a lowpass
`
`filter 38
`
`to a
`
`‘voltage—controlled oscillator 39
`
`to
`
`cause
`
`it
`
`to change
`
`its frequency fRx
`
`so that
`
`the
`
`above—mentioned phase difference decreases.
`
`In addi—
`
`5
`
`tion,
`
`the phase-locked loops may contain amplifiers
`
`34
`
`and 40
`
`for
`
`increasing the level of
`
`the local
`
`oscillator signals f1x and f“, respectively.
`
`As
`
`is obvious to one skilled in the art,
`
`the
`
`synthesizer 3 may be realized in many ways different-
`
`10
`
`from that
`
`shown
`
`in Figure
`
`2. However,
`
`a
`
`common
`
`feature of all synthesizers is that
`
`they contain at
`
`least one programmable
`
`frequency divider
`
`such that
`
`the synthesized frequency can be changed by varying
`
`the divisor of the divider.
`
`In the preferred embodi—
`
`15
`
`ment of the invention shown in Figure 2,
`
`the divisor
`
`M is programmed by the control unit 4 in the internal
`
`frequency divider registers of
`
`the phase comparators
`
`31 and 37 over the control bus 4A.
`
`Each radio system in which the radio device
`
`20
`
`according to the invention is operative utilizes a
`
`certain number of
`
`radio channels,
`
`e.g. pairs of
`
`transmitting and
`
`receiving frequencies
`
`in a
`
`full
`
`duplex system. For the purpose of internal signalling
`
`in the system,
`
`a channel number is assigned to each
`
`25
`
`radio channel. On transition to a radio channel,
`
`the
`
`control unit 4 generates a divisor M corresponding to
`
`the channel number of
`
`the channel. The divisor M
`
`causes the output frequencies fTX and fRx of the fre—
`
`quency synthesizer 3 to be shifted and locked to the
`
`30
`
`transmitting and receiving frequencies correSpOnding
`
`to the channel number in the current system.
`
`According to the invention,
`
`a divisor' M cor—
`
`responding to a single channel number
`
`is separately
`
`'
`
`stored in a memory 5 for each different radio system
`
`35
`
`in which the radio device is to be used.

`
`I?
`
`ferred embodiment of
`
`the invention,
`
`the divisor M
`
`corresponding to the channel number 0 of
`
`the system
`
`is stored. 0n the basis of
`
`the stored divisor,
`
`the
`
`control unit 4 calculates divisors M corresponding to
`
`5
`
`the other channel numbers
`
`for
`
`the radio system in
`
`which the radio device is currently- operating. The
`
`control unit 4 may select the radio system to be used
`
`in response to a manual user command from a user'
`e.g.
`interface 6.
`
`10
`
`For
`
`instance,
`
`the radio device may operate in
`
`the systems A and B shown in Figure 1.
`
`In this case
`
`the divisor M of
`
`a channel
`
`CHO is stored in the
`
`memory
`
`5
`
`for
`
`the system A. The
`
`stored divisor
`
`M
`
`causes the synthesizer
`3
`to generate e.gn a trans-
`mitting frequency fTx of 410 MHz. Correspondingly,
`a
`
`15
`
`divisor M of the channel CHO is stored for the system
`
`B, as a result of which the synthesizer 3 synthesizes
`
`e.g. a transmitting frequency fTX of 420 MHz. As
`
`the
`
`channel spacing is constant within the radio system,
`e.g. 25 kHz or 12.5 kHz,
`the divisor correSponding to
`
`20
`
`another channel number N can be easily calculated
`
`e.g.
`
`by adding a difference value (N—NO)*AM to the
`
`stored divisor M, where N0 is a channel number car-
`
`responding to the divisor M stored in the memory and
`
`25
`
`AM is the difference value of the divisor correspond-
`
`ing to the channel Spacing in the radio system.
