Eastwind QSA Quality Service Availability

The Quality Service Availability system tests services of the telecom operator, imitating actions of the normal subscriber. In other words, the robot of the platform calls, sends messages, orders services and goes on-line.

The EW QSA system checks availability and quality of services of the operator in the fighting mode. The platform works for standards of communication of GSM, UMTS, LTE, CDMA and fixed connection. For two last standards subscribers act as receivers of calls i.e. as users of other telecom operator.

For integration into third-party applications of QSA has open API. For example, it allows to obtain data from billing and to manage defined settings of discounts and services of the operator.

A system checks 5 types of services:

• ringing traffic;
• acceptance and transfer SMS/USSD;
• quality of Internet connection;
• services in readdressing;
• correctness of change of balance of the personal account at payment acceptance and after tariffing of the call/SMS/transfer of data/readdressing.

The robot tests all types of communication: the entering / outgoing calls and messages in the and in foreign network. Also a system checks quality of voice traffic at commission of calls both from mobile, and from stationary phones.

An important role for the operator is played by tests which control availability of subscriber services. For this purpose a system sends requests for connection/shutdown of services – for example, through USSD or IVR, and fixes response or its absence. So QSA will allow to reveal in time if service works incorrectly. It will reduce finance costs from the recession of connections caused by technical issues.

The tester transfers data retrieveds about checks in Eastwind Monitoring Console where graphic reports form. The technical service of the telecom operator can monitor round the clock results of tests via the automated workplace, and in case of failures – immediately to start troubleshooting. Via the user interface of a system the operator can independently edit and create scenarios of tests – for example, at emergence of new services.
