Baseband Module, Functional Description

Modes of Operation

The phone has the following main operating modes – Analog mode, on 800 MHz band

– Analog Control Channel ACCH – Analog Voice Channel AVCH

– Digital mode, on 800 MHz band

– Digital Control Channel DCCH – Digital Traffic Channel DTCH

NSW-4

– Digital mode, on 1900 MHz band

– Digital Control Channel DCCH

– Digital Traffic Channel DTCH – Out Of Range –mode OOR – Locals mode

Analog Control Channel mode (ACCH

On analog control channel the phone receives continuous signalling messages on Forward Control Channel (FOCC) from base station, being most of the time in IDLE mode. Only the receiver part is on. Occasionally the phone re–scans control channels in order to find the stronger or otherwise preferred control channel.

Also registration (TX on) happens occasionally, whereby the phone sends its information on Reverse Control Channel (RECC) to base station and the phone’s location is updated in the switching office.

If a call is initiated, either by the user or base station, the phone moves to analog voice channel or digital traffic channel mode depending on the orders by the base station.

)

Analog Voice Channel Mode (AVCH)

The phone receives and transmits analog audio signal. All circuitry is powered up except digital rx–parts. In this mode the DSP does all the audio processing and in the Hands Free (HF) mode it also performs echo– cancellation and the HF algorithm. COBBA performs the AD–conversion for the MIC signal, and the DA–conversion for the EAR signal.

Issue 1 08/00

NSW-4 System Module SE2L

With audio signal also SAT (Supervisory Audio Tone) is being received from the base station. The SAT signal can be 5970 Hz, 6000Hz or 6030 Hz, the frequency being defined by the base station. DSP’s DPLL phase lock loops to SAT, detects if the SAT frequency is the expected one and examines the signal quality. DSP reports SAT quality figures to MCU regularly. The received SAT signal is transponded (transmitted back) to base station.

The base station can send signalling messages on Forward Voice Channel (FVC) to the phone, by replacing the audio with a burst of Wide Band Data (WBD). Typically these are handoff or power level messages. System Logic RX–modem is used for receiving the signalling message burst, after which it gives interrupt to MCU for reading the data. During the burst audio path must be muted; MCU gives message to DSP about this. MCU can acknowledge the messages on Reverse Voice Channel (RVC), where DSP sends the WBD to transmitter RF.

Also Signalling Tone (ST) can be transmitted to acknowledge messages from base station. DSP sends ST after MCU’s command.

PAMS Technical Documentation

On Analog Voice Channel MCU uses sleep mode (HW DEEP SLEEP) most of the time, but other circuits are fully operational.

Digital Control Channel Mode (DCCH)

On digital control channel (DCCH) DSP receives the paging information from the Paging channels. DSP sends messages to MCU for processing them.

Each Hyperframe (HFC) comprises two Superframes (SF), the first as the Primary (p) and the second as the Secondary (s) paging frame. The assigned Page Frame Class (PFC) defines the frames which must be received, and thus it also defines when the receiver must be on; i.e. the basic power consumption is defined at the same time.

The phone employs sleep mode between received time slots. Then DSP sets the sleep clock timer and MCU, DSP and RF including VCXO are powered down. Only sleep clock and necessary timers are running.

From DCCH phone may be ordered to analog control channel or to analog or digital traffic channel.

Digital Traffic Channel Mode (DTCH)

Page 12

Digital Voice Channel

On digital voice channel DSP processes speech signal in 20 ms time slots. DSP performs the speech and channel functions in time shared fashion and sleeps whenever possible. Rx and tx are powered on and off according to the slot timing. MCU is waken up mainly by DSP, when there is signalling information for the Cellular Software.

PAMS Technical Documentation

Digital Data Channel

Digital Data Channel is supported in the product.

Out of Range mode (OOR)

If the phone cannot find signal from the base station on any control channel (analog or digital) it can go into OOR mode for power saving.

All RF circuits are powered off and baseband circuits are put into low power mode, VCXO is stopped and only sleep clock is running in MAD and CCONT. After the programmable timer in MAD has elapsed the phone turns receiver on and tries to receive signalling data from base station. If it succeeds, the phone goes to standby mode on analog or digital control channel. If the connection can not be established the phone will return to out of range mode, until the timer elapses again.

Locals Mode

NSW-4

System Module SE2L

Locals mode is used by product development, production and after sales, for testing purposes. MCU’s Cellular Software is stopped (no signalling to base station), and the phone is controlled by MBUS messages from test PC.

These blocks are only functional blocks and therefore have no type nor material codes. For block diagram, see baseband schematics.

The battery voltage range in DCT3 family is 3.0V to 4.5V depending on the battery charge and used cell type (Li–Ion or NiMH). Because of the battery voltage the baseband supply voltage is a nominal of 2.8V.

The baseband is running from a 2.8V power rail which is supplied by a power controlling asic (CCONT). In the CCONT there are seven individually controlled regulator outputs for the RF section, one 2.8V output for the baseband plus a core voltage for MAD1. In addition there is one +5V power supply output(V5V). A real time clock function is integrated into the CCONT which utilizes the same 32KHz clock supply as the sleep clock. A backup power supply is provided for the RTC which keeps the real time

clock running when the main battery is removed. The backup power supply is a rechargeable polyacene battery with a backup time of ten minutes.

The interface between the baseband and the RF section is handled by a specific asic. The COBBA_D asic provides A/D and D/A conversion of the in–phase and quadrature receive and transmit signal paths and also A/D and D/A conversions of received and transmitted audio signals to and from the UI parts. Data transmission between the COBBA_D and the MAD is implemented using serial connections. Digital speech processing is handled by the MAD asic. The COBBA_D asic is a dual supply voltage circuit, the digital parts are running from the baseband supply VBB and the analog parts are running from the analog supply VCOBBA (VR6).

RF monitoring

RF temperature monitoring by VCXOTEMP, ADC in CCONT. Received signal strength monitoring by RSSI, ADC in CCONT. False transmission detection by TXF signal, digital IO–pin.

Power up/down and Watchdog control

When power key is pressed, initial reset (PURX) has happened and default regulators have powered up in CCONT, MCU and DSP take care of the rest of power up procedures (LCD, COBBA, RF). The MCU must regularly reset the Watchdog counter in CCONT, otherwise the power will be switched off.

Accessory monitoring

Accessory detection by EAD (HEADSETINT), AD–converter in CCONT.

Battery and charging monitoring

MCU reads the battery type (BTYPE), temperature (BTEMP) and voltage (VBAT) values by AD–converter in CCONT, and phone’s operation is allowed only if the values are reasonable. Charging current is controlled by writing suitable values to PWM control in CCONT.

Production/after sales tests and tuning
