COSMO

1. GENERAL DESCRIPTION

Cosmo is designed for use with E-GSM/DCS network. This phone operates and complies with the ETSI GSM
Phase 2 specifications.

Standard kit includes following items :

• Tranceiver (retractable antenna type)

• Battery pack (3.8 V 540 mA Li-Ion)

Reference : FZA-0052A

• AC/DC adapter for battery rapid charging (6.5 V 400 mA)

Reference : 2PS304/00

Speech codec :

COSMO uses a speech codec which is able to switch from half rate (HR) to full rate (FR) or to
enhanced full rate (EFR) according to network and the software & settings version.

Enhanced full rate (EFR) allows better voice quality at same rate as full rate.

Half rate (HR) is coding on 5.6 kbits/s (1/2 full rate) the network may put two customers on one time
slot. each customer will use this timeslot every two frames.

2.b IMEI label

IMEI label stands for International Mobile Equipment Identity. The IMEI label is stuck on the rear case of the
terminal. It is held in the logic circuit of the main board itself. If the main board is changed then IMEI will
change.

Date Code is made of 3 digits and indicates the date of shipment from factory.
For example, in J07, J stands for 2000 and 07 for July (12 for december).

Bar code indicates 15 digits 123456 45 456789 4 (for example) of the IMEI written in plain letters above the

bar code:

- 123456 : The 6 first digits indicate the Type Approval Code (different according to type of mobile).

- 45 : These 2 digits are allocated to production site.

- 456789 : The 6 last digits are a sequential number (different for each mobile).

- 4 : Check digit.

2.d SIM Latching

SIM Lock consists in restricting the use of the terminal to a family of SIM cards. For the SIM Lock, three sets
of information are used. This information is read from data fields in the SIM card.

1°) IMSI (International Mobile Subscriber Identity), 15 Digits :

Example of IMSI : 208 01 55 12312312
208 = MCC = Mobile Country Code (ex : 208 for France)
01 = MNC = Network Country Code (ex : 01 for FT)
55 = NS = Network Subset
12312312 = serial number

2°) Group IDentifier 1 (GID1):

This data field can contain digits or letters which identify a family of SIM
Ex : XX for a type for of prepaid SIM card of Service provider Y

3°) Group IDentifier 2 (GID2) :

Same as GID1 to identify a sub family of SIM.

Then, from this information, we have 5 types of latch :

1°) Network Level :

Latch on MCC MNC of IMSI of the SIM only
(ex : only the cards 208 01 are able to operate the mobile.
Mitsubishi calls this latch NCK (NCK stands for “ Network Control Keys” and is the password to lock
the mobile at the network level)

2°) Network Subset Level :

Latch on MCC, MNC and digit 6 and 7 of the IMSI
Ex : latch on 208 01 55, only the SIM cards with an IMSI starting with 208 01 55 will operate the
mobile.
Mitsubishi calls this latch NSCK (“Network Subset Control Key”)

3°) Service provider level :

Latch on Network (value of MCC MNC) and value of GID1 data field.
Ex : latch on the value “XX” in GID1 and MCC MNC=208 01, only the SIM cards of service provider
Y with XX stored in data field GID1 will operate the mobile.
Mitsubishi calls this latch SPCK (Service Provider Control Key)

4°) Corporate Provider Level :

Latch on network (value of MCC and MNC) and a value stored in GID2
Mitsubishi calls this latch CPCK (Corporate Provider Control Key)

5°) IMSI level:

Latch on the complete IMSI of one SIM card.
Only one SIM card corresponding to the correct IMSI operates the mobile. Usually, this latch is done
automatic (the first SIM card inserted in the mobile is the only SIM which can be used by this
mobile).

General information :

To lock /unlock a mobile, you need an 8 digit password for each level concerned, and each mobile (one
set of passwords for one IMEI). These passwords are calculated with a special algorithm. You have
only 10 attempts to unlock a mobile. After 10 unsuccessful attempt, the mobile is permanently blocked.
To enter the unlock procedure, you need to access special menus with specific access codes.

4. TEST AND MEASUREMENTS

4.a E-GSM / DCS measurements

4.a.1 Transmitter Power and Ramp profile

These two are interrelated, since the power ramp shape and its final peak value stored in Serial FLASH as
adjustment values.

The peak power output must lie within 3 dB of specification and be flat to within 0.5 dB over the active period.
The ramp profile is designed to give minimum harmonics, and hence it is important to ensure its adherence.

Power ramp profile must be checked on all frequencies (in practice channels 975, 37 and 124 for the 900 MHz
band and channels 512, 698 and 885 for the 1800 MHz band). In conclusion, the ramp must fit with the mask
at all frequencies and all power levels. The mask is usually stored in the radiocommunication tester. The test
will also be available to cover the frequency and power range automatically.

4.a.2 Phase / Frequency / Time relationship

This is a test for the quality of the modulation including the IQ balance and the Gaussian filters. The phase of
the carrier changes according to the arrival of 1s and 0s. Phase error mustbe less than 20° peak and 5° RMS.

4.a.3 Receiver Bit Error Rate (RX sensitivity)

The specification is a Bit Error Rate (BER) of better than 2.44% for an input signal : -102 dBm for the E-GSM
900 band, and –100 dBm for the DCS 1800 band. There should be no error for -90 dBm to -20 dBm input
signal. The maximum workable error rate is 13%.
It is important that BER and RX sensitivity are good since measures of RXLEV (from -103 to -41 dBm) and
RXQUAL (from 0 to 7) are reported back to the base station on the SACCH to assist in handovers and power
level control. Errors in reporting will lead to sub optimum use of channel space, or interference to others.

4.a.4 Handover between E-GSM 900 & DCS 1800 standards

The M4 dual band may handover from the E-GSM 900 band to the DCS 1800 band automatically. If the
subscribed network (defined in setting) has frequencies in both bands, the M4 dual band will work either in
900 MHz or 1800 MHz band depending on the availability of frequencies.
