Call Validation as a requirement in getting a MSC go LIVE! November 29, 2010

Posted by admin in : ALU, AT&T , add a comment

Performing call validation is an important task in getting a Mobile Switching Center (MSC) go live.

Each calls being done should pass certain requirement and must be 100% completion rate.

There are different call scenarios being done and the following are examples of the kind of calls:

  1. International
  2. National
  3. Local
  4. Operator
  5. CALEA
  6. E911
  7. Special Services

The basic requirement and tools in performing these task are as follows:

  1. Test Phone (i.e. Samsung Rugby a837)
  2. SIM Cards
    • Local SIM
    • Roaming SIM
    • International SIM
  3. Test Plan

Steve Jobs said:

“They’re doing pretty good in some ways and in others they could do better. We meet with them once a quarter. Remember, they deal with way more data traffic than anyone else. And they’re having trouble. But they have the fastest 3G network, and they’re improving. I wish they were improving faster. I’m convinced that any other network, had you put the iPhone on it, would have had the same problems.”

LTE Overview May 21, 2010

LTE (Long Term Evolution) standardization within the 3GPP (3rd Generation Partnership Project) has reached a mature state. Changes in the specification are limited to corrections and bug fixes. Since end 2009 LTE mobile communication systems have been deployed as a natural evolution of GSM (Global system for mobile communications) and UMTS (Universal Mobile Telecommunications System).

The ITU (International Telecommunication Union) has coined the term IMT-Advanced to identify mobile systems whose capabilities go beyond those of IMT 2000 (International Mobile Telecommunications). Specifically data rate requirements have been increased. In order to support advanced services and applications 100Mbps for high and 1Gbps for low mobility scenarios must be realized. Throughout 2009 3GPP has worked on a study with the purpose of identifying the LTE improvements required to meet IMT-Advanced requirements. In September 2009 the 3GPP Partners made a formal submission to the ITU proposing that LTE Release 10 & beyond (LTE Advanced) should be evaluated as a candidate for IMT-Advanced. Beyond achieving technical requirements, a major reason for aligning LTE with the call for IMT-Advanced is that IMT conformant systems will be candidates for future new spectrum bands that are still to be identified. This ensures that today’s deployed LTE mobile networks provide an evolutionary path towards many years of commercial operation.
