1 Cellular Communication

1.1 Coverage Concept

The cellular system 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

A70 Level 2 Service Manual

1.2 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

Contain relevant data of all mobiles located in the serving MSC, but not belong to the area.

Home Location Register, HLR Stores identity and user data of all the mobile users belonging to the area.

Authentication Center, AUC

Provides the HLR with different sets of parameters to complete the authentication of the mobile station.

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.

A70 Level 2 Service Manual

1.3 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.

SIM card using 5V technology is not supported.

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 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.

6 Disassembly of A70

Note: ESD concept; the internal circuits will be more susceptible to ESD because of

the use of exchangeable housing. The construction of the internal block must be/is designed, in the best possible way, to protect the circuit against sparks.

The keypad must be completely closed to prevent any occurrence of an ESD disruptive discharge.

The SIM contacts may be open, thus reachable for ESD contact discharge. This could lead to damage or destruction of the E-Goldlite pins.

It is a requirement for the service personnel to observe ESD protection rules while performing servicing the A70.

7 Reassembly of A70

For the reassembly of the A70, reverse the disassembly procedures from Step 13 to Step1. However there are some areas to be taken note of during reassembling of the phone.

During the installation of the SIM card, make sure that the SIM card is inserted properly and that the golden contact area is facing downwards. Insert the SIM card and push the latch downwards to lock the SIM card into position.

Installation of the SIM card

During the installation of the battery, make sure that the hinges are properly in place (See picture below). Otherwise the battery will not be able to fit into the phone properly.

When placing the screws, set Torque with 17cNm.

8 Mobile Software Programming

The common mobile software available is divided into language groups. However, this software does not contain the specific settings, such as ringing tones, greeting text, and short dial list etc., required by the operator or service provider. Therefore, it is common to have some menu item(s) differ in different variants or are not visible at all. These settings are stored in different memory area of the mobile and will be activated depending on the customer specific model or variant of the phone by a separate test step during the production process.

Due to this separation of common mobile software and customer specific initialization, it is possible to fulfil the demands of the market requiring customization and flexibility. As a consequence the software programming process in the LSO is divided into two different steps as followed:

- Software update to actual version and appropriate language group

- Programming of CUSTOMER SPECIFIC INITIALIZATION

Usage of GRT is mandatory!! For more detail check GRT User manual

A70 Level 2 Service Manual

8.1 Mobile Software Updating

The software of the mobile, 65 series is loaded from a PC directly. Hardware interconnection between the mobile and the PC is shown in Figure 1. Because of the new type of external connector used since 55 series (Slim-Lumberg type) an additional adaptor cable between mobile and boot adaptor is required. Table 1 listed all the hardware requirements

If you use the battery dummy, make sure that the power supply voltage is correctly adjusted.

Generate Codes

In the module “Generate Codes“you can choose to generate:

- Master – Phonecodes

- Simlock Unlock – Codes

Master - Phonecodes The Master – Phonecode is used to unlock blocked mobiles. Master – Phonecodes can only be supplied for mobiles which have been delivered

in a regular manner.

A70 Level 2 Service Manual

Simlock Unlock - Code

The Simlock-Unlock-Codes can only be generated if the following conditions are given:

- Mobile must have an active Simlock inside.

A70 Level 2 Service Manual

Printing IMEI label

The module “Print IMEI label” offers the possibility to re-print IMEI labels for mobiles again.

You are able to print 1 label in just one step. To prevent that misaligned labels are being printed, the setting "Print test labels = " is activated as default. After having printed a well-aligned test label you can uncheck the setting and print the correct label.

Hint:

For correct printing of IMEI labels you must have a Zebra – label printer with special material that fits for label printing. This printer has to be connected to local LPT1 printer port (also see Installation of IMPRINT) and MUST feature a printing resolution of 300dpi.

A70 Level 2 Service Manual

11 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 A70 is L36880-N2770-Axx-x where the last 4 letters specify the housing and software variant.

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.

For example: M3
