WCDMA | GSM Interoperability Tuning Training

Introduction:

WCDMA | GSM Interoperability Tuning Training Course

This WCDMA | GSM Interoperability Tuning Training course will begin with a review of the basic cell selection and reselection behavior of mobile handsets in the network, idle mode behavior from the WCDMA and GSM | GPRS | EDGE point of view, and the parameters that control the cell reselection principles for inter- technology networks. Next, you will study the measurements that the MS performs in GSM | GPRS and WCDMA networks in busy mode as well as signal strength definitions and QoS evaluations. This will be followed by a discussion of the handover evaluation algorithm, including specific features that could change the order of the basic ranking list, and the parameters that could drive selected handovers from GSM -> WCDMA network. We will also study the WCDMA triggering events that could lead to WCDMA -> GSM handovers according to specific formula requirements. The WCDMA | GSM Interoperability Tuning Training course will conclude with a discussion of the appropriate GPRS WCDMA cell change principles.

Operators of heterogeneous GSM | GPRS-WCDMA | HSPA networks face the challenge of setting up WCDMA network parameters for well tuned network interoperability. This is crucial since wrong tuning of the parameters can lead to network overloading in idle (cell selection/reselection) or busy mode (handovers or cell change) of operation and dropped calls or session delays due to excessive outage periods. Appropriate parameter setting depends not only on certain general principles but also on the operator’s network architecture and design strategy. So simple rules of thumb are not often available.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
