Basic knowledge of Telecom Domain for Testers: Learn Telecom Testing (Protocol Testing) with the best Telecom Testing Tools <\/strong><\/p>\n\n\n\n

Before moving deeply into the Telecommunication<\/a> (Telecom) domain, let us first understand what a Domain is <\/strong>and why Domain Knowledge is important<\/a> in the Software Industry.<\/p>\n\n\n\n

In those days, testing was only specific to an application and there was not much involvement of domain in it. But nowadays, with the advancement in technology, demand, client expectations, etc., it is highly important to have the specific domain knowledge to test a specific application. <\/em><\/p>\n\n\n\n

<\/p>\n\n\n\n

Introduction<\/h3>\n\n\n\n

Domain knowledge is essential for a tester because testers having domain knowledge can test their respective software applications better than others who have little or no knowledge of the domain.<\/p>\n\n\n\n

Domain means a specific industry like Banking, Insurance, Telecom, etc. Usually while developing any project or software, domain knowledge is critical as the entire software is dependent on the business logic for that specific industry.<\/p>\n\n\n\n

Business logic is different for each industry, hence we require a domain expert who is a master of the subject and knows the in-and-out of the project.<\/p>\n\n\n\n

Advantages of Having Domain Knowledge<\/h3>\n\n\n\n

Domain knowledge is relatively important for testing any project.<\/p>\n\n\n\n

The list given below shows the various advantages involved in having domain knowledge:<\/strong><\/p>\n\n\n\n

#1) Reduces Training Time<\/span><\/h4>\n\n\n\n

If a tester has domain knowledge then only minimal training is required for them and this, in turn, will save the cost and time of the project.<\/p>\n\n\n\n

#2) Productivity<\/span><\/h4>\n\n\n\n

Any organization having testers with domain knowledge will be productive as testers can understand any problem specific to their domain expertise very easily and provide the exact solution to the problem by reducing the analysis time.<\/p>\n\n\n\n

This will increase the productivity of the project as well as the organization.<\/p>\n\n\n\n

#3) Good understanding of User Interface & back-end processing<\/span><\/h4>\n\n\n\n

A tester with an intense knowledge of the domain can suggest the user interface (UI) of an application from the end-user’s point of view. Also, they can identify the defects at the early stage of testing with the help of their knowledge of the back-end system.<\/p>\n\n\n\n

If a tester has domain knowledge then they can think out of the box and can write unique test cases which may raise valid questions on the current workflow of an application.<\/p>\n\n\n\n

#4) Knowledge of Technical Terms of the domain<\/span><\/h4>\n\n\n\n

Usually, a developer uses technical terms during a discussion, hence domain knowledge will be helpful for a tester during such discussions. This will be an added advantage to the testing team as well.<\/p>\n\n\n\n

If a tester has domain knowledge then they can review the test cases technically and suggest technical changes in the test case flow as per the business requirement.<\/p>\n\n\n\n

#5) Understanding of Business Processes and Rules<\/span><\/h4>\n\n\n\n

Testers with domain knowledge can participate in discussions with the business team and development team. Their knowledge will play a vital role while representing an organization in front of the client. Such testers having a detailed knowledge of the domain processes and rules can easily spot issues in the requirement document.<\/p>\n\n\n\n

#6) An Asset to the Organization<\/span><\/h4>\n\n\n\n

Testers with domain knowledge can play the role of a trainer to the new joiners in the organization. This again saves costs for projects and organizations that otherwise may require a special trainer for coaching.<\/p>\n\n\n\n

Overview of Telecom Domain<\/h3>\n\n\n\n

Telecom industry has become a top-performing industry in the last few years.<\/p>\n\n\n\n

This industry has a unique set of challenges from the technology front and the customer demands due to its wide range of sectors. The Telecom industry consists of a set of sectors like wireless communication, satellite communication, Internet Service Providers, etc.<\/p>\n\n\n\n

The telecom industry builds, maintains, and operates telecommunication networks thereby making communication possible globally through the internet or phone for a human being and this service plays a vital role in anyone\u2019s life.<\/p>\n\n\n\n

Business Processes in the Telecom Industry<\/h3>\n\n\n\n

A good understanding of the business processes is a must for testing a telecom project. This will help to test an end-to-end telecom application.<\/p>\n\n\n\n

Telecom services are based on the below two systems:<\/strong><\/p>\n\n\n\n

#1) Operations Support Systems (OSS):<\/span><\/h4>\n\n\n\n

OSS supports back-office activities like telecom network, provisioning, maintaining customer service, Inventory, etc. Sometimes it is also called Operational Support Systems.<\/p>\n\n\n\n

#2) Business Support Systems (BSS):<\/span><\/h4>\n\n\n\n

BSS deals with Customer Relationship Manager (CRM) and processes such as generating invoices, IVR\u2019s Call Centers, taking orders, processing bills, collecting payments, etc. Customer-facing activities are involved in Business Support Systems.<\/p>\n\n\n\n

OSS and BSS are related to each other and that is explained clearly in the below diagram:<\/strong><\/p>\n\n\n\n

\"OSS<\/a><\/figure>\n\n\n\n

<\/p>\n\n\n\n

BSS and OSS are separated as shown in the above diagram in which passing the customer data or request from the BSS to OSS and provides the required set-up, later activation is done by the OSS and again details are passed on to the customer-facing application from the BSS.<\/p>\n\n\n\n

Understanding the following business processes in the Telecom industry is essential while testing any telecom application:<\/strong><\/span><\/p>\n\n\n\n

#1)<\/strong> In the Telecom Industry, it\u2019s the provider who wants to increase his customers and for that purpose, the Telecom Service Provider (TSP) approaches the customers to provide a new service and checks if the customer is interested in his service.<\/p>\n\n\n\n

#2)<\/strong> If a customer feels that the service is good and wants to go with a specific service then the customer generates an inquiry. Here, the customer is more interested in the quotation of the service or plan.<\/p>\n\n\n\n

#3)<\/strong> Once the customer is satisfied with the initial details and quotes provided by the service provider then the customer orders a service to the TSP.<\/p>\n\n\n\n

#4)<\/strong> Now it’s the service provider\u2019s responsibility for technical evaluation as if the service can be provided in that area or not, whether all requirements of a customer can be fulfilled or not, etc. After the successful evolution, TSP starts working on the execution of the service request to the customer.<\/p>\n\n\n\n

#5)<\/strong> TSP always tracks the order status, for any reason if the order implementation stops then the TSP takes priority to resolve the issue and continues to give service to the customer. After all, in today\u2019s world, customer satisfaction holds the key to success.<\/p>\n\n\n\n

#6)<\/strong> After successful implementation, the client or customer starts using the services and of course, billing also starts from the service provider\u2019s end. The billing will be generated as per the quotation provided earlier to the customer.<\/p>\n\n\n\n

#7)<\/strong> For any technical problems, the service assurance team will always be available to support customer service.<\/p>\n\n\n\n

The telecom business process stated above is explained in detail using the below diagram:<\/strong><\/span><\/p>\n\n\n\n

Protocol Testing<\/h3>\n\n\n\n

In telecommunication, protocol means a set of rules that need to be followed when two connections communicate with each other and these protocols exist at different levels.<\/p>\n\n\n\n

In the Telecom industry, Protocols are classified into two categories as shown below:<\/strong><\/p>\n\n\n\n

#1) Routed Protocols:<\/span><\/h4>\n\n\n\n

In the Telecom industry, the user sends data from one network to another and this data contains files, e-mails, etc. Using these Routed protocols, the user can send such data to a different network at a different location.<\/p>\n\n\n\n

#2) Routing Protocols:<\/span><\/h4>\n\n\n\n

Different types of data can be transferred using Routers. Routing protocols are used to decide the route of the routers and are used between the routers only.<\/p>\n\n\n\n

Types of Protocols<\/h3>\n\n\n\n

Given below are the various types of Protocols:<\/strong><\/p>\n\n\n\n

#1) Transmission Control Protocol\/ Internet Protocol (TCP\/IP)<\/strong>:<\/p>\n\n\n\n

This protocol is used to send information through the internet using packets.<\/p>\n\n\n\n

#2) File Transfer Protocol (FTP):<\/strong><\/p>\n\n\n\n

It is used to transfer a file from one network to another network.<\/p>\n\n\n\n

#3) Simple Mail Transfer Protocol (SMTP):<\/strong><\/p>\n\n\n\n

During e-mail communication, this type of protocol is used to send & receive emails.<\/p>\n\n\n\n

#4) Hypertext Transfer Protocol (HTTP):<\/strong><\/p>\n\n\n\n

It is used to transfer HTML pages in an encrypted form.<\/p>\n\n\n\n

#5) Layer 2 Protocol:<\/strong><\/p>\n\n\n\n

It is a Data Link Layer protocol. E.g.<\/strong> <\/span>Ethernet, Token Ring.<\/p>\n\n\n\n

#6) Layer 3 Protocol:<\/strong><\/p>\n\n\n\n

It is a Network Layer Protocol. E.g.<\/strong><\/span> Internet Protocol.<\/p>\n\n\n\n
