Mobile Testing Theory-ravinder

…by Ravinder Sharma

Description:  A mobile phone (also known as a wireless phone, cell phone, or cellular telephone) is a short-range, electronic device used for mobile voice or data communication over a network of specialised base stations known as cell sites. In addition to the standard voice function of a mobile phone, telephone, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, Bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video. Most current mobile phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones). Cellular Systems:  Mobile phones send and receive radio signals with any number of cell site base stations fitted with microwave antennas. These sites are usually mounted on a tower, pole or building, located throughout populated areas, then connected to a cabled communication. Key technologies:  The key technologies used in cellular mobile radio include cellular frequency reuse, analog cellular (1st generation), digital mobile radio (2nd generation), packet based digital radio (2 ½ generation), and wideband radio (3rd generation).  Even before 3G networks are fully launched and utilized, various study groups are considering the shape of the next generation of cellular technology, so called 4G. There is no single global vision for 4G as yet but the next generation of network is likely to be all IP-based, offer data rates up to 100 Mbps and support true global mobility. One route towards this vision is the convergence of technologies such as 3G cellular and Wireless LANs (WLANs). Frequency reuse:  To conserve the limited amount of radio spectrum (maximum number of available radio channels), the cellular system concept was developed. Cellular systems allow reuse of the same channel frequencies many times within a geographic coverage area.

 1G: First Generation cellular - analog.  2G: Second Generation cellular - digital cellular including TDMA, CDMA, and GSM

systems. Most 2G digital phones are voice only phones, but some offer limited data capability.

 2.5G: Enhanced data rate Second Generation - digital cellular systems with data rates of

28kbps - 384kbps.

 3G: The term 3G refers to third generation wireless networks. These networks offer voice,

data transfer, and multimedia content at rates as high as 2 Mbps.

 GSM: Global System for Mobile communications. GSM is used all over Europe, plus many

countries in the Middle East, Asia, Africa, South America, Australia, and North America. GSM's air interface is based on narrowband TDMA technology, where available frequency bands are divided into time slots, with each user having access to one time slot at regular intervals.

 CDMA: Code Division Multiple Access; also known as IS-95. This is one of the newer

digital technologies in use in the US, Canada, Australia, and some southeastern Asian countries (e.g. Hong Kong and South Korea). CDMA differs from GSM and TDMA by its use of spread spectrum techniques for transmitting voice or data over the air. Rather than dividing the radio frequency spectrum into separate user channels by frequency slices or time slots, spread spectrum technology separates users by assigning them digital codes within the same broad spectrum. Advantages of CDMA include higher user capacity and immunity from interference by other signals. Used in either 800 MHz or 1900 MHz frequency bands.

GSM was designed as a future proof standard, able to provide users with a range of capabilities. The evolution began from 1982 when members of 11 telephone companies of the European Telecommunications body - CEPT, formed a new standard group. In 1988, after the signing of the GSM MoU by 17 countries the GSM work was transferred to ETSI, a standards organization. Since then the membership of the GSM MoU has grown to 169 countries (401 Networks) across the World. GSM is capable of operating at 3 frequency bands: 900MHz, 1800 MHz & 1900 MHz The last 2 are usually known as DCS1800 & PCS1900. Bandwidth: 200kHz, time multiplexing over 8 slots with frequency hopping. Voice Codec: 13 kbit/sec Data bit rates: 9.6 kbits/sec Short Message Service: 160 Characters maximum message length. Requires a SIM Card.

The term refers to the physical equipment of the user. Comprises of 2 parts •

Hardware and software components relating to the radio interface.

•

SIM Card

Each Mobile equipment has a 15 digit International Mobile Equipment Identity number (IMEI)

The SIM Card forms the second part of the MS. The subscriber related information is stored in a non volatile memory of the SIM Card. The permanent data includes the• Mobile Station ISDN Number (MSISDN) • SIM Type • IC Card Identification - SIM Serial Number • SIM Service table • International Mobile Subscriber Identity Number (IMSI) • Personal Identification Number (PIN) • Pin Unlocking Key (PUK) Authentication Key (Ki) •

Once the SIM Card is switched on the following dynamic data is updated • • • • •

Location Information Ciphering Key for encoding List of Carrier frequencies for cell selection during handover and call setup List of blocked networks Home network search

Base Station Subsystem The BSS comprises of all radio related functions of the GSM network. Because of the limited transmitter power of the Base Transceiver Station (BTS), coverage is provided only within a specific geographical area within the network. Thus radio cells are created & the entire network id distributed into cells. Hence the name Cellular Communications was derived.

Base Station Subsystem Comprises of the - Base Transceiver Station (BTS) - Base Station Controller (BSC) The BTS comprises of the transmitting and receiving facilities, including antennas and all the signaling related to the radio interface. Depending on the type of antenna, the BTS supplies one or several cells. The antenna are separated from each other by an angle of 120 degrees. The BSC is responsible for the management of the radio interface through the BTS, namely for reservation and release of radio channels as well as handover management. It also performs the tasks of Paging and signaling functions. One BSC generally manages several BTS’s and is linked via the MSC.

Network and Switching Subsystem Acts as a gateway between the radio network and other networks like the PSTN etc. Comprises of the - Mobile Switching Center (MSC) - Home Location Register (HLR) - Visitor Location Register (VLR)

Mobile Switching Center The MSC is a high performance digital switching center that carries out the normal switching tasks and manages the network. Each MSC is usually allocated several BSCs, and in the area assigned to it, carries out the switching between mobile users and other PLMN. It also forms a link between the mobile radio network and the wire line networks. The MSC is responsible for all the signaling required for setting up, terminating and maintaining connections as per the CCSS7 standard (Roaming).

Home Location Register The HLR is the store for all important information of each mobile subscriber. It stores all information including       

Telephone Number IMEI Number Authentication Key Location area Identifier Equipment type Subscription basis Supplementary services

Each mobile subscriber & his related data are registered only once in the HLR, in which all billing and administrative tasks are carried out. There is usually only one HLR in a network.

Visitor Location Register

The VLR manages the subscribers who are currently roaming in the area under control of the MSC. It stores the information transmitted by the responsible HLR for users under its area thus allowing the MSC to establish a connection. The VLR is also responsible for the allocation of the MSRN & TIMSI. Location area update and call setup functions are performed by the HLR & VLR. A special process keeps the VLR updated of the mobile users movement within the MSC area or change of MSC. The VLR avoids frequent interrogation of the HLR.

Operation Subsystem The functions of the OSS are allocated into 3 areas of responsibilities. - Subscription Management - Network Operation and maintenance - Mobile Equipment Management OSS Comprises of - Operations and Maintenance Center (OMC - S & R) - Authentication Center (AuC) - Equipment Identity Register (EIR)

OSS - Subscription Management Subscription management is able to authenticate a GSM user from the personal data stored in the HLR and provide him the agreed services. This data provides the call charging basis. Subscriber Data is stored & managed in the HLR; information relating to data security in the AuC. Call Charging: The mobile radio user is charged for services on the basis of call-tickets. These are used for billing irrespective of where the call is made in the network. Billing location can be the MSC where the user is located or the Gateway MSC, where the communication is connected to the external network. HLR stores only call related data. Call billing is handled by the OSS Subscriber management. Tariff data is transmitted between the MSC and the HLR over the signaling link.

OSS - OMCS &R The OMC centrally monitors & controls the network elements and ensures the best possible service quality for a network. The management functions of the OMC include administration of subscribers and equipment, billing, generation of statistical data on state and capacity utilization of network elements. OMCS - Looks after the switch related operation & maintenance OMCR - Looks after the radio network related operation & maintenance.

AuC The AuC contains all the information required to protect the subscriber’s identity, his mobile communication against eavesdropping and his right to use the radio services. Authentication algorithms and encryption codes are stored in the AuC, and strict rules apply for the access to this information.

Equipment Management - EIR Management of mobile equipment concerns information about owner and equipment identity. It also coordinates the movement of the equipment including roaming, handover and paging. EIR is a central database in which subscriber and equipment numbers are stored. The database contains a white, grey and black list. The White list contains all the valid IMEI numbers, the Black list contains the list of stolen or suspended IMEI numbers and the Grey list contains the list of IMEI’s of malfunctioning equipment that is not receiving any services.

Call Connect Procedure Network to Mobile Paging Request Channel Request Immediate Assignment Paging Response Network

Mobile Authentication Authentication Response Setup Confirmation Connect Connection Acknowledgment

Mobility Management Network to Mobile • Allocation of new TIMSI - ensures that identity of mobile user is kept confidential. • Authentication - to check whether the identity of the mobile user is valid. • Identification - The mobile gets a request from the network to send an identification parameter - IMSI or IMEI • IMSI Detach - Removal of IMSI, when SIM is removed from the mobile or mobile is switched off

Mobile to Network • Location Update - Updates registration of the location of a mobile by transmitting LAI •Periodic Update •IMSI Attach - Opposite of Detach, indicating the availability of the mobile to the network.

 Till now, Information on a Mobile, Mobile Connectivity, Call connection Procedure &

Setup and General features of a Mobile are explained.

 There are others Places in Mobile Testing where a Tester is needed apart from the

above areas.

 Supported Applications, Browsers, Games, etc are developed and installed on Mobiles

which needs to be tested before they are released/deployed to the clients.

 Hence the need of a tester is as important as a Developer or any other person in

getting the Mobile Industry at its best.

Test Case - Execution

Manual Test Case Execution phase, involves Normal and Exploratory Testing which covers feature & feature interaction testing (Functionality Testing). We are using GSM/GPRS network for testing these features. Due to current Network limitations, 3G related features will be tested in places where 3G network is available. We test features like Browser, MMS, Email, UPA, Games, Connectivity, IM, Security, Themes, SyncML along few other basic features like Messaging, Multimedia, and Telephony. Test Cases will be allocated to the Test Engineers, and Executed Results will be updated in the Test Central by the Test Engineers. The defects found out during testing are logged in DDTS, centralized database as CR, with the relevant severity & priority. The logged defects are tracked until it gets fixed appropriately. Products will be tested under different cycle plans like Pre STRR, ST-1, ST-2, Macro regression, Micro regression, Soak Regression and bug fix cycle till Shipment Acceptance(SA). Proprietary tools like RSD Lite, MiniFlexTool, RTA are used for flashing, flexing, and data logging.

 Bug tracking and reporting in Dynamic Defect Tracking System (DDTS).  Testing features like Browser, MMS, Email, UPA, Connectivity, IM, Security, Themes,

SyncML and few other basic features like Messaging, Multimedia, Telephony and Games.  Interacting with the Client for reporting and issue discussion frequently through IM and Tele Conference.  Preparing the performance metrics of the team on a Monthly basis (on a rotation basis).  Update the team on New Tools and Upcoming Features in your feature areas.

 Test case Development activity includes Test Case Development and Validation.

During the starting phase, the developer will be assigned with a new feature for which Test Cases needs to be developed. New Work CR will be raised for the Assigned Feature. Number of Test Cases will be Estimated by the Developer after analyzing the SUIS/TRS and will be updated in the New Work Development CR after getting the approval from FA Lead. Test Case Design Document, which covers the all the States and Events, will be prepared by the Test case developer using FI Matrix Tool including all the Requirements mentioned in TRS. Prepared Document will be sent to the FA Lead for Approval. FA Lead will Sign-off the Document, if no changes are required.

 During the Next Phase, Test Cases will be developed based on the Test Case Design

Document. Developed Test Cases will be reviewed internally within the Team. The Test Cases, if required, will be modified based on the Internal Review, and will be sent to the FA Lead for Review and Approval. Based on the final review comments, if required, the test cases will be modified, and moved to the Production Branch from the Development Branch. Finally, the New Work CR will be moved to closed state.

 The next phase of Development will be validating the developed Test Cases. A

Validation CR will be raised for validating the Test Cases Developed. Test Cases developed based on the SUIS/TRS will be validated in the Testing Phones. Validator will raise a Test ware CR after getting the approval from the Test Case Developer, in case, if modification is required in the Test Case. A product CR will be raised by the Validator if a defect is found in the Software during the Validation Phase. Finally, the Validation CR will be moved to closed state.

 Analysis of SUIS/TRS for the new feature and estimation of test case to be developed.  Preparation of Test case Design document for the new feature.  Developing test cases for the identified new feature.  Involved in Reviews and Inspections for test cases developed for the new feature.  Validating the new feature, once it gets implemented on the product.

 System test automation phase involves Analysis, Scripts Development & Maintenance.  During initial phase, the TRS / Test Plan / Test Case is analyzed for the feasibility of

automation on the grounds of complexity, time required for execution, repeatability and maintainability of scripts. Once the Analysis Report is approved by our Project Lead, then the Test Cases will be picked up for Automation.

 Next Phase starts with script development which includes Coding, Validation,

Inspection, Inspection rework and Final Release. The released scripts are to be run using automation tool like PTF & STAT.  Types of testing conducted during automation execution process are Regression Testing, Stress Testing, Stability Testing and Performance Testing. Using STAT, Test cases will be picked up from Test Central and Results will be entered accordingly. From the logs provided by STAT, the Test Engineer will analyze, and report the bugs found out, if any, in DDTS with relevant severity & priority. The logged bugs are tracked until it gets closed appropriately.

 Validating and executing the test scripts using PTF and STAT automation tool.  Analyzing the failure of the scripts from the logs provided by STAT Tool.  Involved in executing the test scripts by conducting Stress testing, Stability testing

and Performance testing on the product.  Interacting with client for issue discussion and reporting bugs on weekly basis by either Tele Conference or Net meeting.

 Escape Defect Analysis  Phase Screening Efficiency
