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, same frequency is used by several 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, with each covering a fairly small geographical zone called cell. Cells are often represented by hexagons

(see figure 1.1.).

FIGURE 1.1

CELLULAR COVERAGE REPRESENTATION.

GSM Network Architecture.

GSM network can be broadly divided into three broad parts, namely:

1. Mobile Station(MS) carried by the subscriber,

2. Base Station Sub-system(BSS) which controls the radio link with the mobile station.

3. Mobile Switching Center(MSC) which performs the switching of calls between the mobile users, and between mobile and fixed network users.

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 Location Register, 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 is interrogated about the present address of the VLR.

Home Location Register, HLR

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 immediately to the called party.

Authentication Center, AUC

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, which protects the user information against unwanted disclosure.

Equipment Identity Register, EIR

An option the network operator can use to enforce security. With this feature the network can identify defective or stolen mobile that may not be used in the network.

3

Subscriber Identity 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.

To protect the SIM card from improper use, a security feature, a four digits personal identification number (PIN), is built in. The PIN is stored in the SIM card and can be changed by the subscriber. PIN2 is required for additional functions available with a special SIM card (Consult the operator for more information about the PIN 2).

A code (PUK) is provided for unlocking the SIM card if the SIM card is blocked

.

SIM Application Toolkit

This is a new GSM feature that has been integrated into the GSM standards in Release 96, with further enhancements added as part of the Release 97 feature set. This feature came about because of a desire by Network Operators to offer differentiated services, without the need for the

Mobile Manufacturers having to build different variant for different customers. The unique service offered by the Operator is placed as an application on the SIM and that could work on any mobile that supports the Toolkit feature.

There is a distinct set of commands between the mobile and the SIM specifically for the Toolkit that allows the SIM Toolkit and the mobile to communicate independently of the GSM communication between the SIM and the mobile. Henceforth, the SIM Application Toolkit and

GSM functionality on the SIM are separated logically. The Toolkit can interact directly with the mobile itself and adding itself to the mobile menu.

Currently, Toolkit application on the SIM and its “other half” communicate by using the Short

Message Service(SMS). “Proactive SIM” is a mechanism whereby the SIM can initiate actions to be taken by the mobile. These actions include:

· Display text from the SIM on the Mobile display

· Send short message

· Set up a voice call to a number held by the SIM

· Set up a data call to a number and bearer capabilities held by the SIM

· Send a Supplementary Service (SS) control or Unstructured Supplementary Services Data

(USSD) string

· Play a tone in the mobile’s ear piece or ringer

· Initiate a dialogue with the user

· Provide local information from the mobile to the SIM.

· Data download to the SIM from network

· Call control by the SIM.

SIM Applications Toolkit (SAT) allows the flexibility to update the SIM, to change the services and download new services over the air. In the SAT specification, the short message service is a key mechanism for personalizing the SIM in each user’s GSM phone. It is designed as a client-server application. A50 series supports SAT Class 3 specification.

When active, the name of the service may appear in the menu, and there will be sub-menu if more than one application is active. Figure 1.4 is the SAT icon.

FIGURE 1.4 SAT ICON

Extended GSM 900, E-GSM

This is a new standard that allows Network Operators to increase their capacity through an extended frequency. The frequency range of E-GSM is as follows:

· Mobile Transmit: 880,2 - 914,8 MHz

· Mobile Receive: 925,2 - 959,8 MHz

A50/1168 series is a GSM Phase 2 / Phase 2+ Dualband E-GSM / GSM 1800 mobile phone.

Wireless Application 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 (WML), 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 WAP client (mobile) using the available and most appropriate mobile network bearer services.

Wireless Protocol Stack.

Wireless Application Environment (WAE)

Wireless Session Protocol (WSP)

Wireless Transaction Protocol (WTP)

Wireless Transport Layer Security (WTLS)

Wireless Datagram Protocol (WDP)

Bearers e.g. Data, SMS, USSD

TABLE 1..1 WAP PROTOCOL STACK

1. Wireless Application Environment

Defines the user interface on the phone. WAE contains the WML,WML script and the wireless telephony application (WTA).

2. Wireless Session Protocol

Link the WAE to two session services – one connection oriented operating above the WTP and a connectionless service operating above WDP.

3. Wireless Transaction Protocol

Runs on top of the datagram service and part of the standard suite of TCP/IP protocols, to provide a simplified protocol suitable for low bandwidth mobile station.

4. Wireless Transport Layer Security

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 authentication.

5. Wireless Datagram Protocol

Allows WAP to be bearer independent by adapting the transport layer of the under-laying bearer. WDP presents a consistent data format to the higher layer on the WAP stack.

WAP Internet access via the A50 is possible with the inclusion of Wireless Application Protocol

(WAP) browser 1.2.1.

Note: The Asian variant phone (1168) does not support WAP.

Mechanical Concept

Please take note that the number(s) used here IS NOT the part number, DO NOT used it in your spare parts purchase order.

A l w a y s r e f e r t o t h e S E R V I C E P A R T P R I C E L I S T f o r y o u r s p a r e p a r t o r d e r .

Note: All numbers refer to mechanical drawing in Figure 2.1.

The mechanical concept of the A50/1168 is similar in various points from other Siemens mobile telephones.

The first thing you will experience is how the housing is locked. In A50/1168 no screws are used to keep the housing closed. Also inside the telephone no screws are used anymore. To open the housing, which is kept closed by catches only, a special opening tool has been defined. Once the phone is open the catches will be damage and a new housing need to be used. For details on

disassembly tool please refer to Photo 2.5 in the Disassembly Section of this chapter.

Inside, the A50/1168 consists of just one board (1010), which carries control part and RF section of the mobile.

The display module (1170) and the keypad module (1010) are connected to the board by the flexible cable which is inserted into a plug-in connector. In case the display or keypad is defective electrically or mechanically it can be exchanged very easily.

A50/1168 does have an external connector of a new type. Since S6 a so-called “Molex”connector was used, which also offered the possibility to connect an external antenna to it. The new “Lumberg”-connector, which is used in A50/1168, does not feature such a connection, because the connector for external antenna is located at the back side of the upper end of the mobile, close to the internal antenna. As a consequence of this there is no need anymore for a

RF cable mounted to the board or for a RF plug on it to connect this cable. This improves RFproperties of the mobile and lowers production costs.

To be able to do measurements on and software update of the telephone, an adapter cable between Molex and Lumberg connector will be available. See photos in Additional Tools of

Chapter 3.

A50/1168 antenna is an integral part of the lower case shell (1030).

The A50/1168 is a dual-band mobile operating on GSM900 and

GSM1800, the antenna is an integral part of the lower housing.

The keypad, the microphone and the loudspeaker are mounted into the upper case shell (1020).

Make sure that the microphone and the earphone contact springs are not dirty or damaged during repair process.

International Mobile Equipment Identity, IMEI

The mobile equipment is uniquely identified by the International Mobile Equipment Identity, IMEI, which consists of 15 digits. Type approval granted to a type of mobile is allocated 6 digits. The final assembly code is used to identify the final assembly plant and is assigned with 2 digits. 6 digits have been allocated for the equipment serial number for manufacturer and the last digit is spare.

The part number for the A50 is S30880-S5110-Axxx where the last 4 letters specify the housing and software variant.

A50 series IMEI label is accessible by removing the battery.

Re-use of IMEI label is possible by using a hair-dryer to remove the IMEI label.

On this IMEI label, Siemens has also includes the date code for production or service, which conforms to the industrial standard DIN EN 60062. The date code comprises of 2 characters: first character denotes the Year and the second character denotes the Month. Fr example, the IMEI above show date code M3.

Introduction

Every LSO repairing Siemens handset must ensure that the quality standards are observed.

Siemens has developed an automatic testing system that will perform all necessary measurements. This testing system is known as

S i e m e n s M o b i l e S e r v i c e E q u i p m e n t

Using this system vastly simplifies the repair of the phones and will make sure that:

1. All possible faults are detected

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 testing platform for testing a repaired Siemens mobile phone. The testing platform are either base on R&S CMD

53/55, CMU200; CTS55 GSM test set.

There is also test software available for testing with the Wavetek 4201S, 4400 and the 4107 GSM test set.

THE LSO WILL HAVE TO PURCHASE THE SYSTEM, CHOOSING BETWEEN

THE COMPLETE PACKAGE OR SUB-SET OF IT
