Cellular Communication

Coverage Concept

.

he cellular systems is made up of numerous transmitting and
receiving sites, whose individual coverage areas partially overlap. The
concept of frequency re-use, sam e frequency i s us ed by sever al sites ,

allows a high traffic density in a wide area. Due to the limited
transmission range of the terminals, cellular systems are based on a large
number of base stations on the infrastructure side, scattered over the area to
cover, wit h each c over i ng a fair ly sm al l geogr aphi cal zone c al l ed cel l . C ell s are
often represented by hexagons (s ee figure 1.1.) .

GSM Network Architecture.

GSM network can be br oadl y di v ided i nto thr ee br oad par ts, nam el y:

1. Mobile Stati on( MS) carried by the subsc r i ber,

2. Base Station Sub-system(BSS) whi ch contr ols the r adio l ink w it h the mobi l e station.

3. Mobile Switching Center(MSC) which performs the switching of calls between the mobile
users, and between mobi l e and fixed networ k user s .

FIGURE 1.2 GSM ARCHITECTURE

Each mobile station is given a unique identity. As soon as the mobile phone is turned on, it
registers with the network and is authenticated, as such the network could always find the
mobile phone.
Larger amount of data is being exchanged to and from the following functional blocks in the
MSC:

Visitor Locati on Regi s ter , VLR

Stores information about mobile subscribers that enter it coverage area which is associated with
the geographical area where the mobile is currently roaming. When there is an incoming call for
the mobile, the HLR i s i nter r ogated about the pr esent addr es s of the VLR.

Home Location Regi st er, H LR

A database that contains all data concerning the subscription of the mobile subscriber, i.e. their
access capabilities, subscribed services, and supplementary services. It also contains
information about the VLR that is handling the mobile station currently. When the mobile
changes location, the HLR is updated accordingly. It also provides the MSC with information
about the MSC area where the mobile is actually located to allow incoming calls to be routed
immediatel y to the c all ed par ty.

Authentication Center, AU C

Stored information that is necessary to protect communication through the air interface against
any intrusions. The legitimacy of the subscriber is established through authentication and
ciphering, whi ch pr otec ts the us er i nform ation agai ns t unwanted di sc l osur e.

Equipment Identity R egis ter , EIR

An option the network operator can use to enforce security. With this feature the network can
identify defective or stolen m obi le that m ay not be used i n the netw ork .

Subscriber Identi ty Module(SIM)

SIM is a smart card which has a computer and memory chip that is permanently installed in the
mobile equipment. It comes in either the size of a credit card or smaller version known as the

plug-in SIM.

The subscriber information, which includes a unique number called the International Mobile
Subscriber Identity (IMSI) is stored in the SIM card. SIM card identifies the subscriber to the
network.

FIGURE 1.3 INS ERT SIM CA RD

Figure 1.3 illustrates the steps for inserting the SIM card into the C35 series.

General Information

Due to different requirements of the markets, the C35 series has different variants, which
broadly classified under International version and Asian version. Marketing name for
international ver si on i s C 35 or C 35i, w her eas As i an ver si on i s nam ed 3508 or 3508i .

The 3508 series is equipped with a graphic display which enable the telephone to display
CHINESE c har acter s, ei ther i n Tr adi ti onal font or Si m pli fied font, beside the standar d Engl i sh.

Difference between C35(08) and C35(08)i

C35(08)i mobile software has WAP Browser 1.1 incorporated thus enabling user to surf the
Internet and it have bui l t- i n soft modem for GSM Data Service.

The differences between the C35 and C35i are the hardware and software. The memory size of
C35 is 16M B and that of C35I is 32MB.

There are also two variants for 3508, one without the WAP browser is 3508 and that with WAP
browser ver si on 1.1 i s 3508i . T he different for ASIAN ver si on i s onl y mobi l e softwar e.

Wireless Applic ation Protocol, WAP.

Wireless Application Protocol takes a client-server approach that uses the in-built micro-browser
to make a request, in wireless markup language (W ML), for information or service. The request
is passed to a WAP Gateway which then retrieves the information from a Internet server, in
HTML format, and translate it into WML. The requested information is then sent to from the
WAP Gateway to W AP client (mobile) using the available and most appropriate mobile network
bearer serv ic es.

Wireless Protocol Stack.

Wireless Application Envi r onm ent (WAE)
Wireless Session Protocol ( WSP)

2. Wirelss Session Protocol

Link the WAE to two session services – one connection oriented operating above the WTP
and a connectionless s er vi c e oper ating abov e WDP.

3. Wireless Transaction Pr otocol

Runs on top of the datagram service and part of the standard suite of TCP/IP protocols, to
provide a sim pli fied pr otocol sui tabl e for low bandw idth m obi l e stati on.

4. Wireless Transport Layer Sec uri ty

WTLS incorporates security features that are based upon the established Transport layer
Security (TLS) protocol standard, that include data integrity checks, privacy on the WAP
Gateway to client leg and authenti c ation.

5. Wireless Datagram Protoc ol

Allows WAP to be bearer independent by adapting the transport layer of the under-laying
bearer. WDP presents a consistent data form at to the hi gher l ay er on the WAP stack.

The mechanical c oncept of the C35 di ffers in var i ous poi nts from the one of the other Siem ens
mobile telephones.

The first thing you will experience is how the housing is locked. In C35 no sc r ews ar e used to
keep the housing closed. Al so i nsi de the tel ephone no sc rew s ar e used anym or e. T o open the
housing, which is kept c l osed by c atches onl y, a s peci al openi ng tool has been defined.

Power Supply Concept

The C35 has two mai n power i nputs :

1. Battery voltage(3.6V) c onnected at the batter y contac t

2. Charging voltage(6.5V) delivered by the different charger type(see Accessory List) via the
Lumberg connector at the bottom of the telephone.

Since the battery voltage is supplying the power supply ASIC, it is always needed to operate the
phone.

You cannot switch on the handset if the battery voltage is not present.

From the battery voltage, all other supply voltages are derived and controlled by the power
supply ASIC .

The RF power amplifier is directly connect to the battery, a bad battery with high internal
resistance c an caus e m al function of the C35 phone.

The Logic module us es 1.92V, 2.65V & 2.9V gener ated by v olt age r egulator s ins ide the ASIC.
Furthermore, the ASIC generates the supply voltage for the SIM card and the RESET signal for

the logic devic es.
The ASIC also checks the presence of the watchdog signal from the microprocessor and

provides the swi tc hing on functional i ty (O N_OF F button or Ignition signal).

Wrong polarity or batter y voltage setting that exceed the + 6.5V

could damage the phone.

Over-voltage Conditi on

• Battery voltage
If the supply voltage rises above 6.2V, the phone will switch off and it cannot be switched on

again before the voltage is low er than 6.2V.
If the supply volt age ri s es abov e 7V, the phone can be dam aged

• Charging Current

The charging current must not rise above 1A or a track fuse in the
phone will blow. As a result charging the battery will no longer by
possible.

Be careful with NON-original S I E MEN S accessor ies or char ger s. Make sure that

the charging current is limited to value below 1A.

Battery

C35 series uses a Nickel Metal Hyride (NiMH) 500mAH battery pack as standard battery. It also
support the Lithium Ion 600mAH battery pack (For S35i phone) as optional battery for customer
want longer talk ti me.

PHOTO 2.32 C35 SERIES INSERTING BATTERY.

For C35, BATT+ has a voltage level from +3.0V to 5.5V, and a BATT_TEMP contact is used for
detecting abnormal i ncr eas e in tem per atur e of the battery.

If the temperature is too high or too low, there is a high probability

that the battery is not charged. To enable the charging pr ocess

again, battery and phone needs to cools down or w ar m up. Ba ttery

replacement is not requir ed.

Avoid shorting the battery terminals.

Short Circui t Protection

For the Nickel Metal Hydride battery, a polyswitch in the battery pack protecting the battery from
short circui t and i t shoul d r eset by i tsel f after some tim e rem ovi ng the s hort c ir c uit.

For the Lith ium Ion battery, it is short-circuit protec ted by an ele ctronics fuse. The fuse will be
activated in case a too high current is drawn. This fuse will

not reset

automatically .

The resetting of the L-ion batter y fuse can be done wi th ei ther of the following pr oc edur es:

1. Insert the battery into the C35 and then connect the rapid charger to the phone. Wait for
approximately 10 sec ond, then the m obil e can be tur ned on agai n.

2. Plug the battery separatel y i nto the desk top c harger . T he fuse is r es et im m edi ately .

3. Insert the battery into the C35 and put the phone into the desktop charger. Wait for
approximately 10 sec ond, then the m obil e can be s w itc hed on.

a)

Trickle charge for C35 Phone

Trickl e char ge m ode is autom ati cal ly st arted i f the battery v olt age is bel ow 3.0V w hen the
charger is c onnected to the m obi le. T he char gi ng cur r ent i n Tr i ck l e mode i s appr . 10mA.

Trickl e char ge m ode has to l ast mi ni m um until the batter y v olt age has ex ceeded 3.2V,
then the phone will switch on and the charging icon appear. During tr i ck le c har ge the
charging symbol will not be visible and the telephone can not be turned on. This is
because the battery voltage i s too low to oper ate the tel ephone.

Action:

Insert battery i nto handset and c onnect tr av el c har ger to the telephone. If within 4 hours
the battery voltage is high enough agai n, the c hargi ng s ym bol will come up.

If the battery is dis char ged v ery deepl y, the s ym bol m ay not c ome up and the tr i ck l e

Mobile Software P rogramming

Model before C25 and C35, software used for the mobile are similar except for their differences
in the language group. Customer specific values (e.g. ringing tones etc) are seldom, but there
were some, wer e i ncl uded in the c om m on mobi l e softwar e.

C25 and C35 has changed. Ther e is still a common mobile software available which is divided
into language groups. How ever , thi s s oftware does not contai n the spec i fic setti ngs, s uch as
ringing tones, greeti ng tex t, shor t di al l i st etc ., r equir ed by the operator ( s ) or s er vi ce pr ov ider ( s ) .
Therefore, it is not uncom m on to hav e som e m enu i tem (s ) di ffer in different variants or ar e not
visible at all . T hese s etti ngs ar e st ored i n di fferent memor y ar ea of the mobi le and will be
activated depending on the custom er spec ific model or var i ant of the phone by a separ ate test
step during the produc tion pr oc ess .

Due to this separation of common mobile software and customer specific initialization, it is
possible to fulfill the demands of the market requiring customi zati on and flexi bility.

As a consequence the software programming process in the LSO is divided into two diff erent
steps as followed:

1. Software update to actual versi on and appr opr iate l anguage gr oup

2. Programmi ng of CUST OMER SPECIFIC INIT I ALIZATION

Mobile Software Updati ng

The software of the mobile, C35 series, is loaded from a PC directly. Hardware interconnection

Siemens Mobile Service Equipment

Using this system vastl y sim pl ifies the repai r of the phones and will make sure that:

1. All possible faults are detec ted

2. Set which pass the test will be good enough to return to customer.

Starting from the P35 Series, Siemens will introduce a simpler and faster tes ti ng platform for
testing a repair ed Siem ens mobi l e phone. The tes ti ng platform ar e ei ther base on R &S CMD
53/55 or CTS55 GSM test s et.

There is als o test s oftware under devel opm ent for testi ng w it h the Wavetek 4201S and the 4107
GSM test set.

A Level 2.5 servic e softwar e is al so under devel opm ent for m ore el abor ate test ing for the r epai r
for the P35 series mobil e phone.
